+# Claude Code MCP Configuration Guide
+
+This document explains how to configure MCP (Model Context Protocol) servers for Claude Code, covering both the CLI and VS Code extension.
+
+## The Two Config Files
+
+Claude Code uses **two separate configuration files** for MCP servers. They must be kept in sync manually.
+
+| File                      | Used By                       | Notes                                       |
+| ------------------------- | ----------------------------- | ------------------------------------------- |
+| `~/.claude.json`          | Claude CLI (`claude` command) | Requires `"type": "stdio"` in each server   |
+| `~/.claude/settings.json` | VS Code Extension             | Simpler format, supports `"disabled": true` |
+
+**Important:** Changes to one file do NOT automatically sync to the other!
+
+## File Locations (Windows)
+
+```text
+C:\Users\<username>\.claude.json           # CLI config
+C:\Users\<username>\.claude\settings.json  # VS Code extension config
+```
+
+## Config Format Differences
+
+### VS Code Extension Format (`~/.claude/settings.json`)
+
+```json
+{
+  "mcpServers": {
+    "server-name": {
+      "command": "path/to/executable",
+      "args": ["arg1", "arg2"],
+      "env": {
+        "ENV_VAR": "value"
+      },
+      "disabled": true // Optional - disable without removing
+    }
+  }
+}
+```
+
+### CLI Format (`~/.claude.json`)
+
+The CLI config is a larger file with many settings. The `mcpServers` section is nested within it:
+
+```json
+{
+  "numStartups": 14,
+  "installMethod": "global",
+  // ... other settings ...
+  "mcpServers": {
+    "server-name": {
+      "type": "stdio", // REQUIRED for CLI
+      "command": "path/to/executable",
+      "args": ["arg1", "arg2"],
+      "env": {
+        "ENV_VAR": "value"
+      }
+    }
+  }
+  // ... more settings ...
+}
+```
+
+**Key difference:** CLI format requires `"type": "stdio"` in each server definition.
+
+## Common MCP Server Examples
+
+### Memory (Knowledge Graph)
+
+```json
+// VS Code format
+"memory": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@modelcontextprotocol/server-memory"]
+}
+
+// CLI format
+"memory": {
+  "type": "stdio",
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@modelcontextprotocol/server-memory"],
+  "env": {}
+}
+```
+
+### Filesystem
+
+```json
+// VS Code format
+"filesystem": {
+  "command": "d:\\nodejs\\node.exe",
+  "args": [
+    "c:\\Users\\<user>\\AppData\\Roaming\\npm\\node_modules\\@modelcontextprotocol\\server-filesystem\\dist\\index.js",
+    "d:\\path\\to\\project"
+  ]
+}
+
+// CLI format
+"filesystem": {
+  "type": "stdio",
+  "command": "d:\\nodejs\\node.exe",
+  "args": [
+    "c:\\Users\\<user>\\AppData\\Roaming\\npm\\node_modules\\@modelcontextprotocol\\server-filesystem\\dist\\index.js",
+    "d:\\path\\to\\project"
+  ],
+  "env": {}
+}
+```
+
+### Podman/Docker
+
+```json
+// VS Code format
+"podman": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "podman-mcp-server@latest"],
+  "env": {
+    "DOCKER_HOST": "npipe:////./pipe/podman-machine-default"
+  }
+}
+```
+
+### Gitea
+
+```json
+// VS Code format
+"gitea-myserver": {
+  "command": "d:\\gitea-mcp\\gitea-mcp.exe",
+  "args": ["run", "-t", "stdio"],
+  "env": {
+    "GITEA_HOST": "https://gitea.example.com",
+    "GITEA_ACCESS_TOKEN": "your-token-here"
+  }
+}
+```
+
+### Redis
+
+```json
+// VS Code format
+"redis": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@modelcontextprotocol/server-redis", "redis://localhost:6379"]
+}
+```
+
+### Bugsink (Error Tracking)
+
+**Important:** Bugsink has a different API than Sentry. Use `bugsink-mcp`, NOT `sentry-selfhosted-mcp`.
+
+**Note:** The `bugsink-mcp` npm package is NOT published. You must clone and build from source:
+
+```bash
+# Clone and build bugsink-mcp
+git clone https://github.com/j-shelfwood/bugsink-mcp.git d:\gitea\bugsink-mcp
+cd d:\gitea\bugsink-mcp
+npm install
+npm run build
+```
+
+```json
+// VS Code format (using locally built version)
+"bugsink": {
+  "command": "d:\\nodejs\\node.exe",
+  "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+  "env": {
+    "BUGSINK_URL": "https://bugsink.example.com",
+    "BUGSINK_TOKEN": "your-api-token"
+  }
+}
+
+// CLI format
+"bugsink": {
+  "type": "stdio",
+  "command": "d:\\nodejs\\node.exe",
+  "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+  "env": {
+    "BUGSINK_URL": "https://bugsink.example.com",
+    "BUGSINK_TOKEN": "your-api-token"
+  }
+}
+```
+
+- GitHub: <https://github.com/j-shelfwood/bugsink-mcp>
+- Get token from Bugsink UI: Settings > API Tokens
+- **Do NOT use npx** - the package is not on npm
+
+### Sentry (Cloud or Self-hosted)
+
+For actual Sentry instances (not Bugsink), use:
+
+```json
+"sentry": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@sentry/mcp-server"],
+  "env": {
+    "SENTRY_AUTH_TOKEN": "your-sentry-token"
+  }
+}
+```
+
+## Troubleshooting
+
+### Server Not Loading
+
+1. **Check both config files** - Make sure the server is defined in both `~/.claude.json` AND `~/.claude/settings.json`
+
+2. **Verify server order** - Servers load sequentially. Broken/slow servers can block others. Put important servers first.
+
+3. **Check for timeout** - Each server has 30 seconds to connect. Slow npx downloads can cause timeouts.
+
+4. **Fully restart VS Code** - Window reload is not enough. Close all VS Code windows and reopen.
+
+### Verifying Configuration
+
+**For CLI:**
+
+```bash
+claude mcp list
+```
+
+**For VS Code:**
+
+1. Open VS Code
+2. View → Output
+3. Select "Claude" from the dropdown
+4. Look for MCP server connection logs
+
+### Common Errors
+
+| Error                                | Cause                         | Solution                                                                    |
+| ------------------------------------ | ----------------------------- | --------------------------------------------------------------------------- |
+| `Connection timed out after 30000ms` | Server took too long to start | Move server earlier in config, or use pre-installed packages instead of npx |
+| `npm error 404 Not Found`            | Package doesn't exist         | Check package name spelling                                                 |
+| `The system cannot find the path`    | Wrong executable path         | Verify the command path exists                                              |
+| `Connection closed`                  | Server crashed on startup     | Check server logs, verify environment variables                             |
+
+### Disabling Problem Servers
+
+In `~/.claude/settings.json`, add `"disabled": true`:
+
+```json
+"problem-server": {
+  "command": "...",
+  "args": ["..."],
+  "disabled": true
+}
+```
+
+**Note:** The CLI config (`~/.claude.json`) does not support the `disabled` flag. You must remove the server entirely from that file.
+
+## Adding a New MCP Server
+
+1. **Install/clone the MCP server** (if not using npx)
+
+2. **Add to VS Code config** (`~/.claude/settings.json`):
+
+   ```json
+   "new-server": {
+     "command": "path/to/command",
+     "args": ["arg1", "arg2"],
+     "env": { "VAR": "value" }
+   }
+   ```
+
+3. **Add to CLI config** (`~/.claude.json`) - find the `mcpServers` section:
+
+   ```json
+   "new-server": {
+     "type": "stdio",
+     "command": "path/to/command",
+     "args": ["arg1", "arg2"],
+     "env": { "VAR": "value" }
+   }
+   ```
+
+4. **Fully restart VS Code**
+
+5. **Verify with `claude mcp list`**
+

+
+## Best Practices
+
+1. **Keep configs in sync** - When you change one file, update the other
+
+2. **Order servers by importance** - Put essential servers (memory, filesystem) first
+
+3. **Disable instead of delete** - Use `"disabled": true` in settings.json to troubleshoot
+
+4. **Use node.exe directly** - For faster startup, install packages globally and use `node.exe` instead of `npx`
+
+5. **Store sensitive data in memory** - Use the memory MCP to store API tokens and config for future sessions
+
+---
+
+## Future: MCP Launchpad
+
+**Project:** <https://github.com/kenneth-liao/mcp-launchpad>
+
+MCP Launchpad is a CLI tool that wraps multiple MCP servers into a single interface. Worth revisiting when:
+
+- [ ] Windows support is stable (currently experimental)
+- [ ] Available as an MCP server itself (currently Bash-based)
+
+**Why it's interesting:**
+
+| Benefit                | Description                                                    |
+| ---------------------- | -------------------------------------------------------------- |
+| Single config file     | No more syncing `~/.claude.json` and `~/.claude/settings.json` |
+| Project-level configs  | Drop `mcp.json` in any project for instant MCP setup           |
+| Context window savings | One MCP server in context instead of 10+, reducing token usage |
+| Persistent daemon      | Keeps server connections alive for faster repeated calls       |
+| Tool search            | Find tools across all servers with `mcpl search`               |
+
+**Current limitations:**
+
+- Experimental Windows support
+- Requires Python 3.13+ and uv
+- Claude calls tools via Bash instead of native MCP integration
+- Different mental model (runtime discovery vs startup loading)
+
+---
+
+## Future: Graphiti (Advanced Knowledge Graph)
+
+**Project:** <https://github.com/getzep/graphiti>
+
+Graphiti provides temporal-aware knowledge graphs - it tracks not just facts, but _when_ they became true/outdated. Much more powerful than simple memory MCP, but requires significant infrastructure.
+
+**Ideal setup:** Run on a Linux server, connect via HTTP from Windows:
+
+```json
+// Windows client config (settings.json)
+"graphiti": {
+  "type": "sse",
+  "url": "http://linux-server:8000/mcp/"
+}
+```
+
+**Linux server setup:**
+
+```bash
+git clone https://github.com/getzep/graphiti.git
+cd graphiti/mcp_server
+docker compose up -d  # Starts FalkorDB + MCP server on port 8000
+```
+
+**Requirements:**
+
+- Docker on Linux server
+- OpenAI API key (for embeddings)
+- Port 8000 open on LAN
+
+**Benefits of remote deployment:**
+
+- Heavy lifting (Neo4j/FalkorDB + embeddings) offloaded to Linux
+- Always-on server, Windows connects/disconnects freely
+- Multiple machines can share the same knowledge graph
+- Avoids Windows Docker/WSL2 complexity

+## CRITICAL RULES (READ FIRST)
+
+### Platform: Linux Only (ADR-014)
+
+**ALL tests MUST run in dev container** - Windows results are unreliable.
+
+| Test Result | Container | Windows | Status                   |
+| ----------- | --------- | ------- | ------------------------ |
+| Pass        | Fail      | =       | **BROKEN** (must fix)    |
+| Fail        | Pass      | =       | **PASSING** (acceptable) |
+
+```bash
+# Always test in container
+podman exec -it flyer-crawler-dev npm test
+podman exec -it flyer-crawler-dev npm run type-check
+```
+
+### Database Schema Sync
+
+**CRITICAL**: Keep these files synchronized:
+
+- `sql/master_schema_rollup.sql` (test DB, complete reference)
+- `sql/initial_schema.sql` (fresh install, identical to rollup)
+- `sql/migrations/*.sql` (production ALTER TABLE statements)
+
+Out-of-sync = test failures.
+
+### Communication Style
+
+Ask before assuming. Never assume:
+
+- Steps completed / User knowledge / External services configured / Secrets created
+
+---
+
+## Session Startup Checklist
+
+1. **Memory**: `mcp__memory__read_graph` - Recall project context, credentials, known issues
+2. **Git**: `git log --oneline -10` - Recent changes
+3. **Containers**: `mcp__podman__container_list` - Running state
+4. **PM2 Status**: `podman exec flyer-crawler-dev pm2 status` - Process health (API, Worker, Vite)
+
+---
+

+## Application Overview
+
+**Flyer Crawler** - AI-powered grocery deal extraction and analysis platform.
+
+**Data Flow**: Upload → AI extraction (Gemini) → PostgreSQL → Cache (Redis) → API → React display
+
+**Architecture** (ADR-035):
+
+```text
+Routes → Services → Repositories → Database
+         ↓
+    External APIs (*.server.ts)
+```
+
+**Key Entities**: Flyers, FlyerItems, Stores, StoreLocations, Users, Watchlists, ShoppingLists, Recipes, Achievements
+
+**Full Architecture**: See [docs/architecture/OVERVIEW.md](docs/architecture/OVERVIEW.md)
+
+---
+
+## Dev Container Architecture (ADR-014)
+
+The dev container now matches production by using PM2 for process management.
+
+### Process Management
+
+| Component  | Production             | Dev Container             |
+| ---------- | ---------------------- | ------------------------- |
+| API Server | PM2 cluster mode       | PM2 fork mode + tsx watch |
+| Worker     | PM2 process            | PM2 process + tsx watch   |
+| Frontend   | Static files via NGINX | PM2 + Vite dev server     |
+| Logs       | PM2 logs -> Logstash   | PM2 logs -> Logstash      |
+
+**PM2 Processes in Dev Container**:
+
+- `flyer-crawler-api-dev` - API server (port 3001)
+- `flyer-crawler-worker-dev` - Background job worker
+- `flyer-crawler-vite-dev` - Vite frontend dev server (port 5173)
+
+### Log Aggregation (ADR-050)
+
+All logs flow to Bugsink via Logstash:
+
+| Source            | Log Location                      | Status |
+| ----------------- | --------------------------------- | ------ |
+| Backend (Pino)    | `/var/log/pm2/api-*.log`          | Active |
+| Worker (Pino)     | `/var/log/pm2/worker-*.log`       | Active |
+| Vite              | `/var/log/pm2/vite-*.log`         | Active |
+| PostgreSQL        | `/var/log/postgresql/*.log`       | Active |
+| Redis             | `/var/log/redis/redis-server.log` | Active |
+| NGINX             | `/var/log/nginx/*.log`            | Active |
+| Frontend (Sentry) | Browser -> Bugsink SDK            | Active |
+
+**Key Files**:
+
+- `ecosystem.dev.config.cjs` - PM2 development configuration
+- `scripts/dev-entrypoint.sh` - Container startup script
+- `docker/logstash/bugsink.conf` - Logstash pipeline configuration
+
+**Full Dev Container Guide**: See [docs/development/DEV-CONTAINER.md](docs/development/DEV-CONTAINER.md)
+
+---
+
+## Common Workflows
+
+### Adding a New API Endpoint
+
+1. Add route in `src/routes/{domain}.routes.ts`
+2. Use `validateRequest(schema)` middleware for input validation
+3. Call service layer (never access DB directly from routes)
+4. Return via `sendSuccess()` or `sendPaginated()`
+5. Add tests in `*.routes.test.ts`
+
+**Example Pattern**: See [docs/development/CODE-PATTERNS.md](docs/development/CODE-PATTERNS.md)
+
+### Adding a New Database Operation
+
+1. Add method to `src/services/db/{domain}.db.ts`
+2. Follow naming: `get*` (throws), `find*` (returns null), `list*` (array)
+3. Use `handleDbError()` for error handling
+4. Accept optional `PoolClient` for transaction support
+5. Add unit test
+
+### Adding a Background Job
+
+1. Define queue in `src/services/queues.server.ts`
+2. Add worker in `src/services/workers.server.ts`
+3. Call `queue.add()` from service layer
+

+
+## Known Issues & Gotchas
+
+### Integration Test Issues (Summary)
+
+Common issues with solutions:
+
+1. **Vitest globalSetup context isolation** - Mocks/spies don't share instances → Mark `.todo()` or use Redis-based flags
+2. **Cleanup queue interference** - Worker processes jobs during tests → `cleanupQueue.drain()` and `.pause()`
+3. **Cache staleness** - Direct SQL bypasses cache → `cacheService.invalidateFlyers()` after inserts
+4. **Filename collisions** - Multer predictable names → Use `${Date.now()}-${Math.round(Math.random() * 1e9)}`
+5. **Response format mismatches** - API format changes → Log response bodies, update assertions
+6. **External service failures** - PM2/Redis unavailable → try/catch with graceful degradation
+
+**Full Details**: See test issues section at end of this document or [docs/development/TESTING.md](docs/development/TESTING.md)
+
+### Git Bash Path Conversion (Windows)
+
+Git Bash auto-converts Unix paths, breaking container commands.
+
+**Solutions**:
+
+```bash
+# Use sh -c with single quotes
+podman exec container sh -c '/usr/local/bin/script.sh'
+
+# Use MSYS_NO_PATHCONV=1
+MSYS_NO_PATHCONV=1 podman exec container /path/to/script
+
+# Use Windows paths for host files
+podman cp "d:/path/file" container:/tmp/file
+```
+
+---
+

+## Appendix: Integration Test Issues (Full Details)
+
+### 1. Vitest globalSetup Context Isolation
+
+Vitest's `globalSetup` runs in separate Node.js context. Singletons, spies, mocks do NOT share instances with test files.
+
+**Affected**: BullMQ worker service mocks (AI/DB failure tests)
+
+**Solutions**: Mark `.todo()`, create test-only API endpoints, use Redis-based mock flags
+
+```typescript
+// DOES NOT WORK - different instances
+const { flyerProcessingService } = await import('../../services/workers.server');
+flyerProcessingService._getAiProcessor()._setExtractAndValidateData(mockFn);
+```
+
+### 2. Cleanup Queue Deletes Before Verification
+
+Cleanup worker processes jobs in globalSetup context, ignoring test spies.
+
+**Solution**: Drain and pause queue:
+
+```typescript
+const { cleanupQueue } = await import('../../services/queues.server');
+await cleanupQueue.drain();
+await cleanupQueue.pause();
+// ... test ...
+await cleanupQueue.resume();
+```
+
+### 3. Cache Stale After Direct SQL
+
+Direct `pool.query()` inserts bypass cache invalidation.
+
+**Solution**: `await cacheService.invalidateFlyers();` after inserts
+
+### 4. Test Filename Collisions
+
+Multer predictable filenames cause race conditions.
+
+**Solution**: Use unique suffix: `${Date.now()}-${Math.round(Math.random() * 1e9)}`
+
+### 5. Response Format Mismatches
+
+API formats change: `data.jobId` vs `data.job.id`, nested vs flat, string vs number IDs.
+
+**Solution**: Log response bodies, update assertions
+
+### 6. External Service Availability
+
+PM2/Redis health checks fail when unavailable.
+
+**Solution**: try/catch with graceful degradation or mock

+## Session Startup Checklist
+
+**IMPORTANT**: At the start of every session, perform these steps:
+
+1. **Check Memory First** - Use `mcp__memory__read_graph` or `mcp__memory__search_nodes` to recall:
+   - Project-specific configurations and credentials
+   - Previous work context and decisions
+   - Infrastructure details (URLs, ports, access patterns)
+   - Known issues and their solutions
+
+2. **Review Recent Git History** - Check `git log --oneline -10` to understand recent changes
+
+3. **Check Container Status** - Use `mcp__podman__container_list` to see what's running

+1. State how you will verify this change works (test, bash command, browser check, etc.)
+
+2. Write the test or verification step first
+
+3. Then implement the code
+
+4. Run verification and iterate until it passes
+
+## Git Bash / MSYS Path Conversion Issue (Windows Host)
+
+**CRITICAL ISSUE**: Git Bash on Windows automatically converts Unix-style paths to Windows paths, which breaks Podman/Docker commands.
+
+### Problem Examples:
+
+```bash
+# This FAILS in Git Bash:
+podman exec container /usr/local/bin/script.sh
+# Git Bash converts to: C:/Program Files/Git/usr/local/bin/script.sh
+
+# This FAILS in Git Bash:
+podman exec container bash -c "cat /tmp/file.sql"
+# Git Bash converts /tmp to C:/Users/user/AppData/Local/Temp
+```
+
+### Solutions:
+
+1. **Use `sh -c` instead of `bash -c`** for single-quoted commands:
+
+   ```bash
+   podman exec container sh -c '/usr/local/bin/script.sh'
+   ```
+
+2. **Use double slashes** to escape path conversion:
+
+   ```bash
+   podman exec container //usr//local//bin//script.sh
+   ```
+
+3. **Set MSYS_NO_PATHCONV** environment variable:
+
+   ```bash
+   MSYS_NO_PATHCONV=1 podman exec container /usr/local/bin/script.sh
+   ```
+
+4. **Use Windows paths with forward slashes** when referencing host files:
+   ```bash
+   podman cp "d:/path/to/file" container:/tmp/file
+   ```
+
+**ALWAYS use one of these workarounds when running Bash commands on Windows that involve Unix paths inside containers.**
+
+## Communication Style: Ask Before Assuming
+
+**IMPORTANT**: When helping with tasks, **ask clarifying questions before making assumptions**. Do not assume:
+
+- What steps the user has or hasn't completed
+- What the user already knows or has configured
+- What external services (OAuth providers, APIs, etc.) are already set up
+- What secrets or credentials have already been created
+
+Instead, ask the user to confirm the current state before providing instructions or making recommendations. This prevents wasted effort and respects the user's existing work.
+
+## Platform Requirement: Linux Only
+
+**CRITICAL**: This application is designed to run **exclusively on Linux**. See [ADR-014](docs/adr/0014-containerization-and-deployment-strategy.md) for full details.
+
+### Environment Terminology
+
+- **Dev Container** (or just "dev"): The containerized Linux development environment (`flyer-crawler-dev`). This is where all development and testing should occur.
+- **Host**: The Windows machine running Podman/Docker and VS Code.
+
+When instructions say "run in dev" or "run in the dev container", they mean executing commands inside the `flyer-crawler-dev` container.
+
+### Test Execution Rules
+
+1. **ALL tests MUST be executed in the dev container** - the Linux container environment
+2. **NEVER run tests directly on Windows host** - test results from Windows are unreliable
+3. **Always use the dev container for testing** when developing on Windows
+4. **TypeScript type-check MUST run in dev container** - `npm run type-check` on Windows does not reliably detect errors
+
+See [docs/TESTING.md](docs/TESTING.md) for comprehensive testing documentation.
+
+### How to Run Tests Correctly
+
+```bash
+# If on Windows, first open VS Code and "Reopen in Container"
+# Then run tests inside the dev container:
+npm test           # Run all unit tests
+npm run test:unit  # Run unit tests only
+npm run test:integration  # Run integration tests (requires DB/Redis)
+```
+
+### Running Tests via Podman (from Windows host)
+
+**Note:** This project has 2900+ unit tests. For AI-assisted development, pipe output to a file for easier processing.
+
+The command to run unit tests in the dev container via podman:
+
+```bash
+# Basic (output to terminal)
+podman exec -it flyer-crawler-dev npm run test:unit
+
+# Recommended for AI processing: pipe to file
+podman exec -it flyer-crawler-dev npm run test:unit 2>&1 | tee test-results.txt
+```
+
+The command to run integration tests in the dev container via podman:
+
+```bash
+podman exec -it flyer-crawler-dev npm run test:integration
+```
+
+For running specific test files:
+
+```bash
+podman exec -it flyer-crawler-dev npm test -- --run src/hooks/useAuth.test.tsx
+```
+
+### Why Linux Only?
+
+- Path separators: Code uses POSIX-style paths (`/`) which may break on Windows
+- Shell scripts in `scripts/` directory are Linux-only
+- External dependencies like `pdftocairo` assume Linux installation paths
+- Unix-style file permissions are assumed throughout
+
+### Test Result Interpretation
+
+- Tests that **pass on Windows but fail on Linux** = **BROKEN tests** (must be fixed)
+- Tests that **fail on Windows but pass on Linux** = **PASSING tests** (acceptable)
+
+## Development Workflow
+
+1. Open project in VS Code
+2. Use "Reopen in Container" (Dev Containers extension required) to enter the dev environment
+3. Wait for dev container initialization to complete
+4. Run `npm test` to verify the dev environment is working
+5. Make changes and run tests inside the dev container
+
+## Code Change Verification
+
+After making any code changes, **always run a type-check** to catch TypeScript errors before committing:
+
+```bash
+npm run type-check
+```
+
+This prevents linting/type errors from being introduced into the codebase.
+
+## Quick Reference
+
+| Command                    | Description                  |
+| -------------------------- | ---------------------------- |
+| `npm test`                 | Run all unit tests           |
+| `npm run test:unit`        | Run unit tests only          |
+| `npm run test:integration` | Run integration tests        |
+| `npm run dev:container`    | Start dev server (container) |
+| `npm run build`            | Build for production         |
+| `npm run type-check`       | Run TypeScript type checking |
+
+## Database Schema Files
+
+**CRITICAL**: The database schema files must be kept in sync with each other. When making schema changes:
+
+| File                           | Purpose                                                     |
+| ------------------------------ | ----------------------------------------------------------- |
+| `sql/master_schema_rollup.sql` | Complete schema used by test database setup and reference   |
+| `sql/initial_schema.sql`       | Base schema without seed data, used as standalone reference |
+| `sql/migrations/*.sql`         | Incremental migrations for production database updates      |
+
+**Maintenance Rules:**
+
+1. **Keep `master_schema_rollup.sql` and `initial_schema.sql` in sync** - These files should contain the same table definitions
+2. **When adding columns via migration**, also add them to both `master_schema_rollup.sql` and `initial_schema.sql`
+3. **Migrations are for production deployments** - They use `ALTER TABLE` to add columns incrementally
+4. **Schema files are for fresh installs** - They define the complete table structure
+5. **Test database uses `master_schema_rollup.sql`** - If schema files are out of sync with migrations, tests will fail
+
+**Example:** When `002_expiry_tracking.sql` adds `purchase_date` to `pantry_items`, that column must also exist in the `CREATE TABLE` statements in both `master_schema_rollup.sql` and `initial_schema.sql`.
+
+## Known Integration Test Issues and Solutions
+
+This section documents common test issues encountered in integration tests, their root causes, and solutions. These patterns recur frequently.
+
+### 1. Vitest globalSetup Runs in Separate Node.js Context
+
+**Problem:** Vitest's `globalSetup` runs in a completely separate Node.js context from test files. This means:
+
+- Singletons created in globalSetup are NOT the same instances as those in test files
+- `global`, `globalThis`, and `process` are all isolated between contexts
+- `vi.spyOn()` on module exports doesn't work cross-context
+- Dependency injection via setter methods fails across contexts
+
+**Affected Tests:** Any test trying to inject mocks into BullMQ worker services (e.g., AI failure tests, DB failure tests)
+
+**Solution Options:**
+
+1. Mark tests as `.todo()` until an API-based mock injection mechanism is implemented
+2. Create test-only API endpoints that allow setting mock behaviors via HTTP
+3. Use file-based or Redis-based mock flags that services check at runtime
+
+**Example of affected code pattern:**
+
+```typescript
+// This DOES NOT work - different module instances
+const { flyerProcessingService } = await import('../../services/workers.server');
+flyerProcessingService._getAiProcessor()._setExtractAndValidateData(mockFn);
+// The worker uses a different flyerProcessingService instance!
+```
+
+### 2. BullMQ Cleanup Queue Deleting Files Before Test Verification
+
+**Problem:** The cleanup worker runs in the globalSetup context and processes cleanup jobs even when tests spy on `cleanupQueue.add()`. The spy intercepts calls in the test context, but jobs already queued run in the worker's context.
+
+**Affected Tests:** EXIF/PNG metadata stripping tests that need to verify file contents before deletion
+
+**Solution:** Drain and pause the cleanup queue before the test:
+
+```typescript
+const { cleanupQueue } = await import('../../services/queues.server');
+await cleanupQueue.drain(); // Remove existing jobs
+await cleanupQueue.pause(); // Prevent new jobs from processing
+// ... run test ...
+await cleanupQueue.resume(); // Restore normal operation
+```
+
+### 3. Cache Invalidation After Direct Database Inserts
+
+**Problem:** Tests that insert data directly via SQL (bypassing the service layer) don't trigger cache invalidation. Subsequent API calls return stale cached data.
+
+**Affected Tests:** Any test using `pool.query()` to insert flyers, stores, or other cached entities
+
+**Solution:** Manually invalidate the cache after direct inserts:
+
+```typescript
+await pool.query('INSERT INTO flyers ...');
+await cacheService.invalidateFlyers(); // Clear stale cache
+```
+
+### 4. Unique Filenames Required for Test Isolation
+
+**Problem:** Multer generates predictable filenames in test environments, causing race conditions when multiple tests upload files concurrently or in sequence.
+
+**Affected Tests:** Flyer processing tests, file upload tests
+
+**Solution:** Always use unique filenames with timestamps:
+
+```typescript
+// In multer.middleware.ts
+const uniqueSuffix = `${Date.now()}-${Math.round(Math.random() * 1e9)}`;
+cb(null, `${file.fieldname}-${uniqueSuffix}-${sanitizedOriginalName}`);
+```
+
+### 5. Response Format Mismatches
+
+**Problem:** API response formats may change, causing tests to fail when expecting old formats.
+
+**Common Issues:**
+
+- `response.body.data.jobId` vs `response.body.data.job.id`
+- Nested objects vs flat response structures
+- Type coercion (string vs number for IDs)
+
+**Solution:** Always log response bodies during debugging and update test assertions to match actual API contracts.
+
+### 6. External Service Availability
+
+**Problem:** Tests depending on external services (PM2, Redis health checks) fail when those services aren't available in the test environment.
+
+**Solution:** Use try/catch with graceful degradation or mock the external service checks.
+
+## Secrets and Environment Variables
+
+**CRITICAL**: This project uses **Gitea CI/CD secrets** for all sensitive configuration. There is NO `/etc/flyer-crawler/environment` file or similar local config file on the server.
+
+### Server Directory Structure
+
+| Path                                          | Environment | Notes                                            |
+| --------------------------------------------- | ----------- | ------------------------------------------------ |
+| `/var/www/flyer-crawler.projectium.com/`      | Production  | NO `.env` file - secrets injected via CI/CD only |
+| `/var/www/flyer-crawler-test.projectium.com/` | Test        | Has `.env.test` file for test-specific config    |
+
+### How Secrets Work
+
+1. **Gitea Secrets**: All secrets are stored in Gitea repository settings (Settings → Secrets)
+2. **CI/CD Injection**: Secrets are injected during deployment via `.gitea/workflows/deploy-to-prod.yml` and `deploy-to-test.yml`
+3. **PM2 Environment**: The CI/CD workflow passes secrets to PM2 via environment variables, which are then available to the application
+
+### Key Files for Configuration
+
+| File                                  | Purpose                                              |
+| ------------------------------------- | ---------------------------------------------------- |
+| `src/config/env.ts`                   | Centralized config with Zod schema validation        |
+| `ecosystem.config.cjs`                | PM2 process config - reads from `process.env`        |
+| `.gitea/workflows/deploy-to-prod.yml` | Production deployment with secret injection          |
+| `.gitea/workflows/deploy-to-test.yml` | Test deployment with secret injection                |
+| `.env.example`                        | Template showing all available environment variables |
+| `.env.test`                           | Test environment overrides (only on test server)     |
+
+### Adding New Secrets
+
+To add a new secret (e.g., `SENTRY_DSN`):
+
+1. Add the secret to Gitea repository settings
+2. Update the relevant workflow file (e.g., `deploy-to-prod.yml`) to inject it:
+
+   ```yaml
+   SENTRY_DSN: ${{ secrets.SENTRY_DSN }}
+   ```
+
+3. Update `ecosystem.config.cjs` to read it from `process.env`
+4. Update `src/config/env.ts` schema if validation is needed
+5. Update `.env.example` to document the new variable
+
+### Current Gitea Secrets
+
+**Shared (used by both environments):**
+
+- `DB_HOST` - Database host (shared PostgreSQL server)
+- `JWT_SECRET` - Authentication
+- `GOOGLE_MAPS_API_KEY` - Google Maps
+- `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET` - Google OAuth
+- `GH_CLIENT_ID`, `GH_CLIENT_SECRET` - GitHub OAuth
+- `SENTRY_AUTH_TOKEN` - Bugsink API token for source map uploads (create at Settings > API Keys in Bugsink)
+
+**Production-specific:**
+
+- `DB_USER_PROD`, `DB_PASSWORD_PROD` - Production database credentials (`flyer_crawler_prod`)
+- `DB_DATABASE_PROD` - Production database name (`flyer-crawler`)
+- `REDIS_PASSWORD_PROD` - Redis password (uses database 0)
+- `VITE_GOOGLE_GENAI_API_KEY` - Gemini API key for production
+- `SENTRY_DSN`, `VITE_SENTRY_DSN` - Bugsink error tracking DSNs (production projects)
+
+**Test-specific:**
+
+- `DB_USER_TEST`, `DB_PASSWORD_TEST` - Test database credentials (`flyer_crawler_test`)
+- `DB_DATABASE_TEST` - Test database name (`flyer-crawler-test`)
+- `REDIS_PASSWORD_TEST` - Redis password (uses database 1 for isolation)
+- `VITE_GOOGLE_GENAI_API_KEY_TEST` - Gemini API key for test
+- `SENTRY_DSN_TEST`, `VITE_SENTRY_DSN_TEST` - Bugsink error tracking DSNs (test projects)
+
+### Test Environment
+
+The test environment (`flyer-crawler-test.projectium.com`) uses **both** Gitea CI/CD secrets and a local `.env.test` file:
+
+- **Gitea secrets**: Injected during deployment via `.gitea/workflows/deploy-to-test.yml`
+- **`.env.test` file**: Located at `/var/www/flyer-crawler-test.projectium.com/.env.test` for local overrides
+- **Redis database 1**: Isolates test job queues from production (which uses database 0)
+- **PM2 process names**: Suffixed with `-test` (e.g., `flyer-crawler-api-test`)
+
+### Database User Setup (Test Environment)
+
+**CRITICAL**: The test database requires specific PostgreSQL permissions to be configured manually. Schema ownership alone is NOT sufficient - explicit privileges must be granted.
+
+**Database Users:**
+
+| User                 | Database             | Purpose    |
+| -------------------- | -------------------- | ---------- |
+| `flyer_crawler_prod` | `flyer-crawler-prod` | Production |
+| `flyer_crawler_test` | `flyer-crawler-test` | Testing    |
+
+**Required Setup Commands** (run as `postgres` superuser):
+
+```bash
+# Connect as postgres superuser
+sudo -u postgres psql
+
+# Create the test database and user (if not exists)
+CREATE DATABASE "flyer-crawler-test";
+CREATE USER flyer_crawler_test WITH PASSWORD 'your-password-here';
+
+# Grant ownership and privileges
+ALTER DATABASE "flyer-crawler-test" OWNER TO flyer_crawler_test;
+\c "flyer-crawler-test"
+ALTER SCHEMA public OWNER TO flyer_crawler_test;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_test;
+
+# Create required extension (must be done by superuser)
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+```
+
+**Why These Steps Are Necessary:**
+
+1. **Schema ownership alone is insufficient** - PostgreSQL requires explicit `GRANT CREATE, USAGE` privileges even when the user owns the schema
+2. **uuid-ossp extension** - Required by the application for UUID generation; must be created by a superuser before the app can use it
+3. **Separate users for prod/test** - Prevents accidental cross-environment data access; each environment has its own credentials in Gitea secrets
+
+**Verification:**
+
+```bash
+# Check schema privileges (should show 'UC' for flyer_crawler_test)
+psql -d "flyer-crawler-test" -c "\dn+ public"
+
+# Expected output:
+#  Name  |       Owner        |            Access privileges
+# -------+--------------------+------------------------------------------
+# public | flyer_crawler_test | flyer_crawler_test=UC/flyer_crawler_test
+```
+
+### Dev Container Environment
+
+The dev container runs its own **local Bugsink instance** - it does NOT connect to the production Bugsink server:
+
+- **Local Bugsink UI**: Accessible at `https://localhost:8443` (proxied from `http://localhost:8000` by nginx)
+- **Admin credentials**: `admin@localhost` / `admin`
+- **Bugsink Projects**: Backend (Dev) - Project ID 1, Frontend (Dev) - Project ID 2
+- **Configuration Files**:
+  - `compose.dev.yml` - Sets default DSNs using `127.0.0.1:8000` protocol (for initial container setup)
+  - `.env.local` - **OVERRIDES** compose.dev.yml with `localhost:8000` protocol (this is what the app actually uses)
+  - **CRITICAL**: `.env.local` takes precedence over `compose.dev.yml` environment variables
+- **DSN Configuration**:
+  - **Backend DSN** (Node.js/Express): Configured in `.env.local` as `SENTRY_DSN=http://<key>@localhost:8000/1`
+  - **Frontend DSN** (React/Browser): Configured in `.env.local` as `VITE_SENTRY_DSN=http://<key>@localhost:8000/2`
+  - **Why localhost instead of 127.0.0.1?** The `.env.local` file was created separately and uses `localhost` which works fine in practice
+- **HTTPS Setup**: Self-signed certificates auto-generated with mkcert on container startup (for UI access only, not for Sentry SDK)
+- **CSRF Protection**: Django configured with `SECURE_PROXY_SSL_HEADER` to trust `X-Forwarded-Proto` from nginx
+- **Isolated**: Dev errors stay local, don't pollute production/test dashboards
+- **No Gitea secrets needed**: Everything is self-contained in the container
+- **Accessing Errors**:
+  - **Via Browser**: Open `https://localhost:8443` and login to view issues
+  - **Via MCP**: Configure a second Bugsink MCP server pointing to `http://localhost:8000` (see MCP Servers section below)
+
+---
+
+## MCP Servers
+
+The following MCP servers are configured for this project:
+
+| Server              | Purpose                                                                      |

+| gitea-torbonium     | Gitea API for gitea.torbonium.com                                            |
+| podman              | Container management                                                         |
+| filesystem          | File system access                                                           |
+| fetch               | Web fetching                                                                 |
+| markitdown          | Convert documents to markdown                                                |
+| sequential-thinking | Step-by-step reasoning                                                       |
+| memory              | Knowledge graph persistence                                                  |
+| postgres            | Direct database queries (localhost:5432)                                     |
+| playwright          | Browser automation and testing                                               |
+| redis               | Redis cache inspection (localhost:6379)                                      |
+| bugsink             | Error tracking - production Bugsink (bugsink.projectium.com) - **PROD/TEST** |
+| bugsink-dev         | Error tracking - dev container Bugsink (localhost:8000) - **DEV CONTAINER**  |
+
+**Note:** MCP servers work in both **Claude CLI** and **Claude Code VS Code extension** (as of January 2026).
+
+**CRITICAL**: There are **TWO separate Bugsink MCP servers**:
+
+- **bugsink**: Connects to production Bugsink at `https://bugsink.projectium.com` for production and test server errors
+- **bugsink-dev**: Connects to local dev container Bugsink at `http://localhost:8000` for local development errors
+
+### Bugsink MCP Server Setup (ADR-015)
+
+**IMPORTANT**: You need to configure **TWO separate MCP servers** - one for production/test, one for local dev.
+
+#### Installation (shared for both servers)
+
+```bash
+# Clone the bugsink-mcp repository (NOT sentry-selfhosted-mcp)
+git clone https://github.com/j-shelfwood/bugsink-mcp.git
+cd bugsink-mcp
+npm install
+npm run build
+```
+
+#### Production/Test Bugsink MCP (bugsink)
+
+Add to `.claude/mcp.json`:
+
+```json
+{
+  "bugsink": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "https://bugsink.projectium.com",
+      "BUGSINK_API_TOKEN": "<get-from-production-bugsink>",
+      "BUGSINK_ORG_SLUG": "sentry"
+    }
+  }
+}
+```
+
+**Get the auth token**:
+
+- Navigate to https://bugsink.projectium.com
+- Log in with production credentials
+- Go to Settings > API Keys
+- Create a new API key with read access
+
+#### Dev Container Bugsink MCP (bugsink-dev)
+
+Add to `.claude/mcp.json`:
+
+```json
+{
+  "bugsink-dev": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "http://localhost:8000",
+      "BUGSINK_API_TOKEN": "<get-from-local-bugsink>",
+      "BUGSINK_ORG_SLUG": "sentry"
+    }
+  }
+}
+```
+
+**Get the auth token**:
+
+- Navigate to http://localhost:8000 (or https://localhost:8443)
+- Log in with `admin@localhost` / `admin`
+- Go to Settings > API Keys
+- Create a new API key with read access
+
+#### MCP Tool Usage
+
+When using Bugsink MCP tools, remember:
+
+- `mcp__bugsink__*` tools connect to **production/test** Bugsink
+- `mcp__bugsink-dev__*` tools connect to **dev container** Bugsink
+- Available capabilities for both:
+  - List projects and issues
+  - View detailed error events and stacktraces
+  - Search by error message or stack trace
+  - Update issue status (resolve, ignore)
+  - Create releases
+
+### SSH Server Access
+
+Claude Code can execute commands on the production server via SSH:
+
+```bash
+# Basic command execution
+ssh root@projectium.com "command here"
+
+# Examples:
+ssh root@projectium.com "systemctl status logstash"
+ssh root@projectium.com "pm2 list"
+ssh root@projectium.com "tail -50 /var/www/flyer-crawler.projectium.com/logs/app.log"
+```
+
+**Use cases:**

+
+## Logstash Configuration (ADR-050)
+
+The production server uses **Logstash** to aggregate logs from multiple sources and forward errors to Bugsink for centralized error tracking.
+
+**Log Sources:**
+
+- **PostgreSQL function logs** - Structured JSON logs from `fn_log()` helper function
+- **PM2 worker logs** - Service logs from BullMQ job workers (stdout)
+- **Redis logs** - Operational logs (INFO level) and errors
+- **NGINX logs** - Access logs (all requests) and error logs
+
+### Configuration Location
+
+**Primary configuration file:**
+
+- `/etc/logstash/conf.d/bugsink.conf` - Complete Logstash pipeline configuration
+
+**Related files:**
+
+- `/etc/postgresql/14/main/conf.d/observability.conf` - PostgreSQL logging configuration
+- `/var/log/postgresql/*.log` - PostgreSQL log files
+- `/home/gitea-runner/.pm2/logs/*.log` - PM2 worker logs
+- `/var/log/redis/redis-server.log` - Redis logs
+- `/var/log/nginx/access.log` - NGINX access logs
+- `/var/log/nginx/error.log` - NGINX error logs
+- `/var/log/logstash/*.log` - Logstash file outputs (operational logs)
+- `/var/lib/logstash/sincedb_*` - Logstash position tracking files
+
+### Key Features
+
+1. **Multi-source aggregation**: Collects logs from PostgreSQL, PM2 workers, Redis, and NGINX
+2. **Environment-based routing**: Automatically detects production vs test environments and routes errors to the correct Bugsink project
+3. **Structured JSON parsing**: Extracts `fn_log()` function output from PostgreSQL logs and Pino JSON from PM2 workers
+4. **Sentry-compatible format**: Transforms events to Sentry format with `event_id`, `timestamp`, `level`, `message`, and `extra` context
+5. **Error filtering**: Only forwards WARNING and ERROR level messages to Bugsink
+6. **Operational log storage**: Stores non-error logs (Redis INFO, NGINX access, PM2 operational) to `/var/log/logstash/` for analysis
+7. **Request monitoring**: Categorizes NGINX requests by status code (2xx, 3xx, 4xx, 5xx) and identifies slow requests
+
+### Common Maintenance Commands
+
+```bash
+# Check Logstash status
+systemctl status logstash
+
+# Restart Logstash after configuration changes
+systemctl restart logstash
+
+# Test configuration syntax
+/usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/bugsink.conf
+
+# View Logstash logs
+journalctl -u logstash -f
+
+# Check Logstash stats (events processed, failures)
+curl -XGET 'localhost:9600/_node/stats/pipelines?pretty' | jq '.pipelines.main.plugins.filters'
+
+# Monitor PostgreSQL logs being processed
+tail -f /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log
+
+# View operational log outputs
+tail -f /var/log/logstash/pm2-workers-$(date +%Y-%m-%d).log
+tail -f /var/log/logstash/redis-operational-$(date +%Y-%m-%d).log
+tail -f /var/log/logstash/nginx-access-$(date +%Y-%m-%d).log
+
+# Check disk usage of log files
+du -sh /var/log/logstash/
+```

+
+## Getting Started
+
+### Prerequisites
+
+1. **Windows with Podman Desktop**: See [docs/getting-started/INSTALL.md](docs/getting-started/INSTALL.md)
+2. **Node.js 20+**: For running the application
+3. **Git**: For version control
+
+### Initial Setup
+
+```bash
+# Clone the repository
+git clone <repository-url>
+cd flyer-crawler.projectium.com
+
+# Install dependencies
+npm install
+
+# Start development containers
+podman start flyer-crawler-postgres flyer-crawler-redis
+
+# Start development server
+npm run dev
+```
+
+## Development Workflow
+
+### Before Making Changes
+
+1. **Read [CLAUDE.md](CLAUDE.md)** - Project guidelines and patterns
+2. **Review relevant ADRs** in [docs/adr/](docs/adr/) - Understand architectural decisions
+3. **Check existing issues** - Avoid duplicate work
+4. **Create a feature branch** - Use descriptive names
+
+```bash
+git checkout -b feature/descriptive-name
+# or
+git checkout -b fix/issue-description
+```
+
+### Making Changes
+
+#### Code Changes
+
+Follow the established patterns from [docs/development/CODE-PATTERNS.md](docs/development/CODE-PATTERNS.md):
+
+1. **Routes** → **Services** → **Repositories** → **Database**
+2. Never access the database directly from routes
+3. Use Zod schemas for input validation
+4. Follow ADR-034 repository naming conventions:
+   - `get*` - Throws NotFoundError if not found
+   - `find*` - Returns null if not found
+   - `list*` - Returns empty array if none found
+
+#### Database Changes
+
+When modifying the database schema:
+
+1. Create migration: `sql/migrations/NNNN-description.sql`
+2. Update `sql/master_schema_rollup.sql` (complete schema)
+3. Update `sql/initial_schema.sql` (identical to rollup)
+4. Test with integration tests
+
+**CRITICAL**: Schema files must stay synchronized. See [CLAUDE.md#database-schema-sync](CLAUDE.md#database-schema-sync).
+
+#### NGINX Configuration Changes
+
+When modifying NGINX configurations on the production or test servers:
+
+1. Make changes on the server at `/etc/nginx/sites-available/`
+2. Test with `sudo nginx -t` and reload with `sudo systemctl reload nginx`
+3. Update the reference copies in the repository root:
+   - `etc-nginx-sites-available-flyer-crawler.projectium.com` - Production
+   - `etc-nginx-sites-available-flyer-crawler-test-projectium-com.txt` - Test
+4. Commit the updated reference files
+
+These reference files serve as version-controlled documentation of the deployed configurations.
+
+### Testing
+
+**IMPORTANT**: All tests must run in the dev container.
+
+```bash
+# Run all tests
+podman exec -it flyer-crawler-dev npm test
+
+# Run specific test file
+podman exec -it flyer-crawler-dev npm test -- --run src/path/to/file.test.ts
+
+# Type check
+podman exec -it flyer-crawler-dev npm run type-check
+```
+
+#### Before Committing
+
+1. Write tests for new features
+2. Update existing tests if behavior changes
+3. Run full test suite
+4. Run type check
+5. Verify documentation is updated
+
+See [docs/development/TESTING.md](docs/development/TESTING.md) for detailed testing guidelines.
+
+## Code Standards
+
+### TypeScript
+
+- Use strict TypeScript mode
+- Define types in `src/types/*.ts` files
+- Avoid `any` - use `unknown` if type is truly unknown
+- Follow ADR-027 for naming conventions
+
+### Error Handling
+
+```typescript
+// Repository layer (ADR-001)
+import { handleDbError, NotFoundError } from '../services/db/errors.db';
+
+try {
+  const result = await client.query(query, values);
+  if (result.rows.length === 0) {
+    throw new NotFoundError('Flyer', id);
+  }
+  return result.rows[0];
+} catch (error) {
+  throw handleDbError(error);
+}
+```
+
+### API Responses
+
+```typescript
+// Route handlers (ADR-028)
+import { sendSuccess, sendError } from '../utils/apiResponse';
+
+// Success response
+return sendSuccess(res, flyer, 'Flyer retrieved successfully');
+
+// Paginated response
+return sendPaginated(res, {
+  items: flyers,
+  total: count,
+  page: 1,
+  pageSize: 20,
+});
+```
+
+### Transactions
+
+```typescript
+// Multi-operation changes (ADR-002)
+import { withTransaction } from '../services/db/transaction.db';
+
+await withTransaction(async (client) => {
+  await flyerDb.createFlyer(flyerData, client);
+  await flyerItemDb.createItems(items, client);
+  // Automatically commits on success, rolls back on error
+});
+```
+
+## Testing Requirements
+
+### Test Coverage
+
+- **Unit tests**: All service functions, utilities, and helpers
+- **Integration tests**: API endpoints, database operations
+- **E2E tests**: Critical user flows
+
+### Test Patterns
+
+See [docs/subagents/TESTER-GUIDE.md](docs/subagents/TESTER-GUIDE.md) for:
+
+- Test helper functions
+- Mocking patterns
+- Known testing issues and solutions
+
+### Test Naming
+
+```typescript
+// Good test names
+describe('FlyerService.createFlyer', () => {
+  it('should create flyer with valid data', async () => { ... });
+  it('should throw ValidationError when store_id is missing', async () => { ... });
+  it('should rollback transaction on item creation failure', async () => { ... });
+});
+```

 # Flyer Crawler - Grocery AI Analyzer
 
-Flyer Crawler is a web application that uses the Google Gemini AI to extract, analyze, and manage data from grocery store flyers. Users can upload flyer images or PDFs, and the application will automatically identify items, prices, and sale dates, storing the structured data in a PostgreSQL database for historical analysis, price tracking, and personalized deal alerts.
+Flyer Crawler is a web application that uses Google Gemini AI to extract, analyze, and manage data from grocery store flyers. Users can upload flyer images or PDFs, and the application automatically identifies items, prices, and sale dates, storing structured data in a PostgreSQL database for historical analysis, price tracking, and personalized deal alerts.
 
-We are working on an app to help people save money, by finding good deals that are only advertized in store flyers/ads. So, the primary purpose of the site is to make uploading flyers as easy as possible and as accurate as possible, and to store peoples needs, so sales can be matched to needs.
+**Our mission**: Help people save money by finding good deals that are only advertised in store flyers. The app makes uploading flyers as easy and accurate as possible, and matches sales to users' needs.
+
+---
 
 ## Features
 
-- **AI-Powered Data Extraction**: Upload PNG, JPG, or PDF flyers to automatically extract store names, sale dates, and a detailed list of items with prices and quantities.

-## Required Secrets & Configuration
+## Quick Start
 
-This project is configured to run in a CI/CD environment and does not use `.env` files. All configuration and secrets must be provided as environment variables. For deployments using the included Gitea workflows, these must be configured as **repository secrets** in your Gitea instance.
-
-- **`DB_HOST`, `DB_USER`, `DB_PASSWORD`**: Credentials for your PostgreSQL server. The port is assumed to be `5432`.
-- **`DB_DATABASE_PROD`**: The name of your production database.
-- **`REDIS_PASSWORD_PROD`**: The password for your production Redis instance.
-- **`REDIS_PASSWORD_TEST`**: The password for your test Redis instance.
-- **`JWT_SECRET`**: A long, random, and secret string for signing authentication tokens.
-- **`VITE_GOOGLE_GENAI_API_KEY`**: Your Google Gemini API key.
-- **`GOOGLE_MAPS_API_KEY`**: Your Google Maps Geocoding API key.
-
-## Setup and Installation
-
-### Step 1: Set Up PostgreSQL Database
-
-1. **Set up a PostgreSQL database instance.**
-2. **Run the Database Schema**:
-   - Connect to your database using a tool like `psql` or DBeaver.
-   - Open `sql/schema.sql.txt`, copy its entire contents, and execute it against your database.
-   - This will create all necessary tables, functions, and relationships.
-
-### Step 2: Install Dependencies and Run the Application
-
-1. **Install Dependencies**:
-
-   ```bash
-   npm install
-   ```
-
-2. **Run the Application**:
-
-   ```bash
-   npm run start:prod
-   ```
-
-### Step 3: Seed Development Users (Optional)
-
-To create the initial `admin@example.com` and `user@example.com` accounts, you can run the seed script:
+### Development with Podman Containers
 
 ```bash
-npm run seed
+# 1. Start PostgreSQL and Redis containers
+podman start flyer-crawler-postgres flyer-crawler-redis
+
+# 2. Install dependencies (first time only)
+npm install
+
+# 3. Run in development mode
+npm run dev
 ```
 
-After running, you may need to restart your IDE's TypeScript server to pick up the changes.
+The application will be available at:
 
-## NGINX mime types issue
+- **Frontend**: http://localhost:5173
+- **Backend API**: http://localhost:3001
 
-sudo nano /etc/nginx/mime.types
+See [docs/getting-started/INSTALL.md](docs/getting-started/INSTALL.md) for detailed setup instructions including:
 
-change
+- Podman Desktop installation
+- Container configuration
+- Database initialization
+- Environment variables
 
-application/javascript js;
+### Testing
 
-TO
+**IMPORTANT**: All tests must run inside the dev container for reliable results.
 
-application/javascript js mjs;
+```bash
+# Run all tests in container
+podman exec -it flyer-crawler-dev npm test
 
-RESTART NGINX
+# Run only unit tests
+podman exec -it flyer-crawler-dev npm run test:unit
 
-sudo nginx -t
-sudo systemctl reload nginx
+# Run only integration tests
+podman exec -it flyer-crawler-dev npm run test:integration
+```
 
-actually the proper change was to do this in the /etc/nginx/sites-available/flyer-crawler.projectium.com file
-
-## for OAuth
-
-1. Get Google OAuth Credentials
-   This is a crucial step that you must do outside the codebase:
-
-Go to the Google Cloud Console.
-
-Create a new project (or select an existing one).
-
-In the navigation menu, go to APIs & Services > Credentials.
-
-Click Create Credentials > OAuth client ID.
-
-Select Web application as the application type.
-
-Under Authorized redirect URIs, click ADD URI and enter the URL where Google will redirect users back to your server. For local development, this will be: http://localhost:3001/api/auth/google/callback.
-
-Click Create. You will be given a Client ID and a Client Secret.
-
-2. Get GitHub OAuth Credentials
-   You'll need to obtain a Client ID and Client Secret from GitHub:
-
-Go to your GitHub profile settings.
-
-Navigate to Developer settings > OAuth Apps.
-
-Click New OAuth App.
-
-Fill in the required fields:
-
-Application name: A descriptive name for your app (e.g., "Flyer Crawler").
-Homepage URL: The base URL of your application (e.g., http://localhost:5173 for local development).
-Authorization callback URL: This is where GitHub will redirect users after they authorize your app. For local development, this will be: <http://localhost:3001/api/auth/github/callback>.
-Click Register application.
-
-You will be given a Client ID and a Client Secret.

-Switch to the postgres system user to get superuser access to the database.
+See [INSTALL.md](INSTALL.md) for the complete list.
 
-bash
-sudo -u postgres psql
-Inside the psql shell, run the following SQL commands. Remember to replace 'a_very_strong_password' with a secure password that you will manage with a secrets tool or in your .env file.
+---
 
-sql
--- Create a new role (user) for your application
-CREATE ROLE flyer_crawler_user WITH LOGIN PASSWORD 'a_very_strong_password';
+## Scripts
 
--- Create the production database and assign ownership to the new user
-CREATE DATABASE "flyer-crawler-prod" WITH OWNER = flyer_crawler_user;

-CREATE EXTENSION IF NOT EXISTS postgis;
-CREATE EXTENSION IF NOT EXISTS pg_trgm;
-CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+## License
 
--- Exit the psql shell
-
-Step 3: Apply the Master Schema
-Now, you'll populate your new database with all the tables, functions, and initial data. Your master_schema_rollup.sql file is perfect for this.
-
-Navigate to your project's root directory on the server.
-
-Run the following command to execute the master schema script against your new production database. You will be prompted for the password you created in the previous step.
-
-bash
-psql -U flyer_crawler_user -d "flyer-crawler-prod" -f sql/master_schema_rollup.sql
-This single command creates all tables, extensions (pg_trgm, postgis), functions, and triggers, and seeds essential data like categories and master items.
-
-Step 4: Seed the Admin Account (If Needed)
-Your application has a separate script to create the initial admin user. To run it, you must first set the required environment variables in your shell session.
-
-bash
-
-# Set variables for the current session
-
-export DB_USER=flyer_crawler_user DB_PASSWORD=your_password DB_NAME="flyer-crawler-prod" ...
-
-# Run the seeding script
-
-npx tsx src/db/seed_admin_account.ts
-Your production database is now ready!
-
-Part 2: Test Database Setup (for CI/CD)
-Your Gitea workflow (deploy.yml) already automates the creation and teardown of the test database during the pipeline run. The steps below are for understanding what the workflow does and for manual setup if you ever need to run tests outside the CI pipeline.
-
-The process your CI pipeline follows is:
-
-Setup (sql/test_setup.sql):
-
-As the postgres superuser, it runs sql/test_setup.sql.
-This creates a temporary role named test_runner.
-It creates a separate database named "flyer-crawler-test" owned by test_runner.
-Schema Application (src/tests/setup/global-setup.ts):
-
-The test runner (vitest) executes the global-setup.ts file.
-This script connects to the "flyer-crawler-test" database using the temporary credentials.
-It then runs the same sql/master_schema_rollup.sql file, ensuring your test database has the exact same structure as production.
-Test Execution:
-
-Your tests run against this clean, isolated "flyer-crawler-test" database.
-Teardown (sql/test_teardown.sql):
-
-After tests complete (whether they pass or fail), the if: always() step in your workflow ensures that sql/test_teardown.sql is executed.
-This script terminates any lingering connections to the test database, drops the "flyer-crawler-test" database completely, and drops the test_runner role.
-
-Part 3: Test Database Setup (for CI/CD and Local Testing)
-Your Gitea workflow and local test runner rely on a permanent test database. This database needs to be created once on your server. The test runner will automatically reset the schema inside it before every test run.
-
-Step 1: Create the Test Database
-On your server, switch to the postgres system user to get superuser access.
-
-bash
-sudo -u postgres psql
-Inside the psql shell, create a new database. We will assign ownership to the same flyer_crawler_user that your application uses. This user needs to be the owner to have permission to drop and recreate the schema during testing.
-
-sql
--- Create the test database and assign ownership to your existing application user
-CREATE DATABASE "flyer-crawler-test" WITH OWNER = flyer_crawler_user;
-
--- Connect to the newly created test database
-\c "flyer-crawler-test"
-
--- Install the required extensions as a superuser. This only needs to be done once.
-CREATE EXTENSION IF NOT EXISTS postgis;
-CREATE EXTENSION IF NOT EXISTS pg_trgm;
-CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
-
--- Connect to the newly created test database
-\c "flyer-crawler-test"
-
--- Grant ownership of the public schema within this database to your application user.
--- This is CRITICAL for allowing the test runner to drop and recreate the schema.
-ALTER SCHEMA public OWNER TO flyer_crawler_user;
-
--- Exit the psql shell
-\q
-
-Step 2: Configure Gitea Secrets for Testing
-Your CI pipeline needs to know how to connect to this test database. Ensure the following secrets are set in your Gitea repository settings:
-
-DB_HOST: The hostname of your database server (e.g., localhost).
-DB_PORT: The port for your database (e.g., 5432).
-DB_USER: The user for the database (e.g., flyer_crawler_user).
-DB_PASSWORD: The password for the database user.
-The workflow file (.gitea/workflows/deploy.yml) is configured to use these secrets and will automatically connect to the "flyer-crawler-test" database when it runs the npm test command.
-
-How the Test Workflow Works
-The CI pipeline no longer uses sudo or creates/destroys the database on each run. Instead, the process is now:
-
-Setup: The vitest global setup script (src/tests/setup/global-setup.ts) connects to the permanent "flyer-crawler-test" database.
-
-Schema Reset: It executes sql/drop_tables.sql (which runs DROP SCHEMA public CASCADE) to completely wipe all tables, functions, and triggers.
-
-Schema Application: It then immediately executes sql/master_schema_rollup.sql to build a fresh, clean schema and seed initial data.
-
-Test Execution: Your tests run against this clean, isolated schema.
-
-This approach is faster, more reliable, and removes the need for sudo access within the CI pipeline.

-## dev server setup:
-
-Here are the steps to set up the development environment on Windows using Podman with an Ubuntu container:
-
-1. Install Prerequisites on Windows
-   Install WSL 2: Podman on Windows relies on the Windows Subsystem for Linux. Install it by running wsl --install in an administrator PowerShell.
-   Install Podman Desktop: Download and install Podman Desktop for Windows.
-
-2. Set Up Podman
-   Initialize Podman: Launch Podman Desktop. It will automatically set up its WSL 2 machine.
-   Start Podman: Ensure the Podman machine is running from the Podman Desktop interface.
-
-3. Set Up the Ubuntu Container
-
-- Pull Ubuntu Image: Open a PowerShell or command prompt and pull the latest Ubuntu image:
-  podman pull ubuntu:latest
-- Create a Podman Volume: Create a volume to persist node_modules and avoid installing them every time the container starts.
-  podman volume create node_modules_cache
-- Run the Ubuntu Container: Start a new container with the project directory mounted and the necessary ports forwarded.
-  - Open a terminal in your project's root directory on Windows.
-  - Run the following command, replacing D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com with the full path to your project:
-
-podman run -it -p 3001:3001 -p 5173:5173 --name flyer-dev -v "D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com:/app" -v "node_modules_cache:/app/node_modules" ubuntu:latest
-
--p 3001:3001: Forwards the backend server port.
--p 5173:5173: Forwards the Vite frontend server port.
---name flyer-dev: Names the container for easy reference.
--v "...:/app": Mounts your project directory into the container at /app.
--v "node_modules_cache:/app/node_modules": Mounts the named volume for node_modules.
-
-4. Configure the Ubuntu Environment
-   You are now inside the Ubuntu container's shell.
-
-- Update Package Lists:
-  apt-get update
-- Install Dependencies: Install curl, git, and nodejs (which includes npm).
-  apt-get install -y curl git
-  curl -sL https://deb.nodesource.com/setup_20.x | bash -
-  apt-get install -y nodejs
-- Navigate to Project Directory:
-  cd /app
-
-- Install Project Dependencies:
-  npm install
-
-5. Run the Development Server
-   - Start the Application:
-     npm run dev
-
-6. Accessing the Application
-
-- Frontend: Open your browser and go to http://localhost:5173.
-- Backend: The frontend will make API calls to http://localhost:3001.
-
-Managing the Environment
-
-- Stopping the Container: Press Ctrl+C in the container terminal, then type exit.
-- Restarting the Container:
-  podman start -a -i flyer-dev
-
-## for me:
-
-cd /mnt/d/gitea/flyer-crawler.projectium.com/flyer-crawler.projectium.com
-podman run -it -p 3001:3001 -p 5173:5173 --name flyer-dev -v "$(pwd):/app" -v "node_modules_cache:/app/node_modules" ubuntu:latest
-
-      rate limiting
-
-      respect the AI service's rate limits, making it more stable and robust. You can adjust the GEMINI_RPM environment variable in your production environment as needed without changing the code.

-# Flyer Crawler - Development Environment Setup
-
-Quick start guide for getting the development environment running with Podman containers.
-
-## Prerequisites
-
-- **Windows with WSL 2**: Install WSL 2 by running `wsl --install` in an administrator PowerShell
-- **Podman Desktop**: Download and install [Podman Desktop for Windows](https://podman-desktop.io/)
-- **Node.js 20+**: Required for running the application
-
-## Quick Start - Container Environment
-
-### 1. Initialize Podman
-
-```powershell
-# Start Podman machine (do this once after installing Podman Desktop)
-podman machine init
-podman machine start
-```
-
-### 2. Start Required Services
-
-Start PostgreSQL (with PostGIS) and Redis containers:
-
-```powershell
-# Navigate to project directory
-cd D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com
-
-# Start PostgreSQL with PostGIS
-podman run -d \
-  --name flyer-crawler-postgres \
-  -e POSTGRES_USER=postgres \
-  -e POSTGRES_PASSWORD=postgres \
-  -e POSTGRES_DB=flyer_crawler_dev \
-  -p 5432:5432 \
-  docker.io/postgis/postgis:15-3.3
-
-# Start Redis
-podman run -d \
-  --name flyer-crawler-redis \
-  -e REDIS_PASSWORD="" \
-  -p 6379:6379 \
-  docker.io/library/redis:alpine
-```
-
-### 3. Wait for PostgreSQL to Initialize
-
-```powershell
-# Wait a few seconds, then check if PostgreSQL is ready
-podman exec flyer-crawler-postgres pg_isready -U postgres
-# Should output: /var/run/postgresql:5432 - accepting connections
-```
-
-### 4. Install Required PostgreSQL Extensions
-
-```powershell
-podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "CREATE EXTENSION IF NOT EXISTS postgis; CREATE EXTENSION IF NOT EXISTS pg_trgm; CREATE EXTENSION IF NOT EXISTS \"uuid-ossp\";"
-```
-
-### 5. Apply Database Schema
-
-```powershell
-# Apply the complete schema with URL constraints enabled
-podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/master_schema_rollup.sql
-```
-
-### 6. Verify URL Constraints Are Enabled
-
-```powershell
-podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "\d public.flyers" | grep -E "(image_url|icon_url|Check)"
-```
-
-You should see:
-```
- image_url     | text                     |           | not null |
- icon_url      | text                     |           | not null |
-Check constraints:
-    "flyers_icon_url_check" CHECK (icon_url ~* '^https?://.*'::text)
-    "flyers_image_url_check" CHECK (image_url ~* '^https?://.*'::text)
-```
-
-### 7. Set Environment Variables and Start Application
-
-```powershell
-# Set required environment variables
-$env:NODE_ENV="development"
-$env:DB_HOST="localhost"
-$env:DB_USER="postgres"
-$env:DB_PASSWORD="postgres"
-$env:DB_NAME="flyer_crawler_dev"
-$env:REDIS_URL="redis://localhost:6379"
-$env:PORT="3001"
-$env:FRONTEND_URL="http://localhost:5173"
-
-# Install dependencies (first time only)
-npm install
-
-# Start the development server (runs both backend and frontend)
-npm run dev
-```
-
-The application will be available at:
-- **Frontend**: http://localhost:5173
-- **Backend API**: http://localhost:3001
-
-## Managing Containers
-
-### View Running Containers
-```powershell
-podman ps
-```
-
-### Stop Containers
-```powershell
-podman stop flyer-crawler-postgres flyer-crawler-redis
-```
-
-### Start Containers (After They've Been Created)
-```powershell
-podman start flyer-crawler-postgres flyer-crawler-redis
-```
-
-### Remove Containers (Clean Slate)
-```powershell
-podman stop flyer-crawler-postgres flyer-crawler-redis
-podman rm flyer-crawler-postgres flyer-crawler-redis
-```
-
-### View Container Logs
-```powershell
-podman logs flyer-crawler-postgres
-podman logs flyer-crawler-redis
-```
-
-## Database Management
-
-### Connect to PostgreSQL
-```powershell
-podman exec -it flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev
-```
-
-### Reset Database Schema
-```powershell
-# Drop all tables
-podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/drop_tables.sql
-
-# Reapply schema
-podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/master_schema_rollup.sql
-```
-
-### Seed Development Data
-```powershell
-npm run db:reset:dev
-```
-
-## Running Tests
-
-### Unit Tests
-```powershell
-npm run test:unit
-```
-
-### Integration Tests
-
-**IMPORTANT**: Integration tests require the PostgreSQL and Redis containers to be running.
-
-```powershell
-# Make sure containers are running
-podman ps
-
-# Run integration tests
-npm run test:integration
-```
-
-## Troubleshooting
-
-### Podman Machine Issues
-If you get "unable to connect to Podman socket" errors:
-```powershell
-podman machine start
-```
-
-### PostgreSQL Connection Refused
-Make sure PostgreSQL is ready:
-```powershell
-podman exec flyer-crawler-postgres pg_isready -U postgres
-```
-
-### Port Already in Use
-If ports 5432 or 6379 are already in use, you can either:
-1. Stop the conflicting service
-2. Change the port mapping when creating containers (e.g., `-p 5433:5432`)
-
-### URL Validation Errors
-The database now enforces URL constraints. All `image_url` and `icon_url` fields must:
-- Start with `http://` or `https://`
-- Match the regex pattern: `^https?://.*`
-
-Make sure the `FRONTEND_URL` environment variable is set correctly to avoid URL validation errors.
-
-## ADR Implementation Status
-
-This development environment implements:
-
-- **ADR-0002**: Transaction Management ✅
-  - All database operations use the `withTransaction` pattern
-  - Automatic rollback on errors
-  - No connection pool leaks
-
-- **ADR-0003**: Input Validation ✅
-  - Zod schemas for URL validation
-  - Database constraints enabled
-  - Validation at API boundaries
-
-## Development Workflow
-
-1. **Start Containers** (once per development session)
-   ```powershell
-   podman start flyer-crawler-postgres flyer-crawler-redis
-   ```
-
-2. **Start Application**
-   ```powershell
-   npm run dev
-   ```
-
-3. **Make Changes** to code (auto-reloads via `tsx watch`)
-
-4. **Run Tests** before committing
-   ```powershell
-   npm run test:unit
-   npm run test:integration
-   ```
-
-5. **Stop Application** (Ctrl+C)
-
-6. **Stop Containers** (optional, or leave running)
-   ```powershell
-   podman stop flyer-crawler-postgres flyer-crawler-redis
-   ```
-
-## PM2 Worker Setup (Production-like)
-
-To test with PM2 workers locally:
-
-```powershell
-# Install PM2 globally (once)
-npm install -g pm2
-
-# Start the worker
-pm2 start npm --name "flyer-crawler-worker" -- run worker:prod
-
-# View logs
-pm2 logs flyer-crawler-worker
-
-# Stop worker
-pm2 stop flyer-crawler-worker
-pm2 delete flyer-crawler-worker
-```
-
-## Next Steps
-
-After getting the environment running:
-
-1. Review [docs/adr/](docs/adr/) for architectural decisions
-2. Check [sql/master_schema_rollup.sql](sql/master_schema_rollup.sql) for database schema
-3. Explore [src/routes/](src/routes/) for API endpoints
-4. Review [src/types.ts](src/types.ts) for TypeScript type definitions
-
-## Common Environment Variables
-
-Create these environment variables for development:
-
-```powershell
-# Database
-$env:DB_HOST="localhost"
-$env:DB_USER="postgres"
-$env:DB_PASSWORD="postgres"
-$env:DB_NAME="flyer_crawler_dev"
-$env:DB_PORT="5432"
-
-# Redis
-$env:REDIS_URL="redis://localhost:6379"
-
-# Application
-$env:NODE_ENV="development"
-$env:PORT="3001"
-$env:FRONTEND_URL="http://localhost:5173"
-
-# Authentication (generate your own secrets)
-$env:JWT_SECRET="your-dev-jwt-secret-change-this"
-$env:SESSION_SECRET="your-dev-session-secret-change-this"
-
-# AI Services (get your own API keys)
-$env:VITE_GOOGLE_GENAI_API_KEY="your-google-genai-api-key"
-$env:GOOGLE_MAPS_API_KEY="your-google-maps-api-key"
-```

+# Development SSL Certificates
+
+This directory contains SSL certificates for the development container HTTPS setup.
+
+## Files
+
+| File            | Purpose                                              | Generated By               |
+| --------------- | ---------------------------------------------------- | -------------------------- |
+| `localhost.crt` | SSL certificate for localhost and 127.0.0.1          | mkcert (in Dockerfile.dev) |
+| `localhost.key` | Private key for localhost.crt                        | mkcert (in Dockerfile.dev) |
+| `mkcert-ca.crt` | Root CA certificate for trusting mkcert certificates | mkcert                     |
+
+## Certificate Details
+
+The `localhost.crt` certificate includes the following Subject Alternative Names (SANs):
+
+- `DNS:localhost`
+- `IP Address:127.0.0.1`
+- `IP Address:::1` (IPv6 localhost)
+
+This allows the development server to be accessed via both `https://localhost/` and `https://127.0.0.1/` without SSL errors.
+
+## Installing the CA Certificate (Recommended)
+
+To avoid SSL certificate warnings in your browser, install the mkcert CA certificate on your system.
+
+### Windows
+
+1. Double-click `mkcert-ca.crt`
+2. Click **"Install Certificate..."**
+3. Select **"Local Machine"** > Next
+4. Select **"Place all certificates in the following store"**
+5. Click **Browse** > Select **"Trusted Root Certification Authorities"** > OK
+6. Click **Next** > **Finish**
+7. Restart your browser
+
+### macOS
+
+```bash
+sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain certs/mkcert-ca.crt
+```
+
+### Linux
+
+```bash
+# Ubuntu/Debian
+sudo cp certs/mkcert-ca.crt /usr/local/share/ca-certificates/mkcert-ca.crt
+sudo update-ca-certificates
+
+# Fedora/RHEL
+sudo cp certs/mkcert-ca.crt /etc/pki/ca-trust/source/anchors/
+sudo update-ca-trust
+```
+
+### Firefox (All Platforms)
+
+Firefox uses its own certificate store:
+
+1. Open Firefox Settings
+2. Search for "Certificates"
+3. Click **"View Certificates"**
+4. Go to **"Authorities"** tab
+5. Click **"Import..."**
+6. Select `certs/mkcert-ca.crt`
+7. Check **"Trust this CA to identify websites"**
+8. Click **OK**
+
+## After Installation
+
+Once the CA certificate is installed:
+
+- Your browser will trust all mkcert certificates without warnings
+- Access `https://localhost/` with no security warnings
+- Images from `https://127.0.0.1/flyer-images/` will load without SSL errors
+
+## Regenerating Certificates
+
+If you need to regenerate the certificates (e.g., after rebuilding the container):
+
+```bash
+# Inside the container
+cd /app/certs
+mkcert localhost 127.0.0.1 ::1
+mv localhost+2.pem localhost.crt
+mv localhost+2-key.pem localhost.key
+nginx -s reload
+
+# Copy the new CA to the host
+podman cp flyer-crawler-dev:/app/certs/mkcert-ca.crt ./certs/mkcert-ca.crt
+```
+
+Then reinstall the CA certificate as described above.
+
+## Security Note
+
+**DO NOT** commit the private key (`localhost.key`) to version control in production projects. For this development-only project, the certificates are checked in for convenience since they're only used locally with self-signed certificates.
+
+The certificates in this directory are automatically generated by the Dockerfile.dev and should not be used in production.

+# ============================================================================
+# Development Nginx Configuration (HTTPS)
+# ============================================================================
+# This configuration matches production by using HTTPS on port 443 with
+# self-signed certificates generated by mkcert. Port 80 redirects to HTTPS.
+#
+# This allows the dev container to work the same way as production:
+#   - Frontend accessible on https://localhost (port 443)
+#   - Backend API on http://localhost:3001
+#   - Port 80 redirects to HTTPS
+#
+# IMPORTANT: Dual Hostname Configuration (localhost AND 127.0.0.1)
+# ============================================================================
+# The server_name directive includes BOTH 'localhost' and '127.0.0.1' to
+# prevent SSL certificate errors when resources use different hostnames.
+#
+# Problem Scenario:
+#   1. User accesses site via https://localhost/
+#   2. Database stores image URLs as https://127.0.0.1/flyer-images/...
+#   3. Browser treats these as different origins, showing ERR_CERT_AUTHORITY_INVALID
+#
+# Solution:
+#   - mkcert generates certificates valid for: localhost, 127.0.0.1, ::1
+#   - NGINX accepts requests to BOTH hostnames using the same certificate
+#   - Users can access via either hostname without SSL warnings
+#
+# The self-signed certificate is generated in Dockerfile.dev with:
+#   mkcert localhost 127.0.0.1 ::1
+#
+# This creates a certificate with Subject Alternative Names (SANs) for all
+# three hostnames, allowing NGINX to serve valid HTTPS for each.

+# Bugsink MCP Troubleshooting Guide
+
+This document tracks known issues and solutions for the Bugsink MCP server integration with Claude Code.
+
+## Issue History
+
+### 2026-01-22: Server Name Prefix Collision (LATEST)
+
+**Problem:**
+
+- `bugsink-dev` MCP server never starts (tools not available)
+- Production `bugsink` MCP works fine
+- Manual test works: `BUGSINK_URL=http://localhost:8000 BUGSINK_TOKEN=<token> node d:/gitea/bugsink-mcp/dist/index.js`
+- Configuration correct, environment variables correct, but server silently skipped
+
+**Root Cause:**
+Claude Code silently skips MCP servers when server names share prefixes (e.g., `bugsink` and `bugsink-dev`).
+Debug logs showed `bugsink-dev` was NEVER started - no "Starting connection" message ever appeared.
+
+**Discovery Method:**
+
+- Analyzed Claude Code debug logs at `C:\Users\games3\.claude\debug\*.txt`
+- Found that MCP startup messages only showed: `memory`, `bugsink`, `redis`, `gitea-projectium`, etc.
+- `bugsink-dev` was completely absent from startup sequence
+- No error was logged - server was silently filtered out
+
+**Solution Attempts:**
+
+**Attempt 1:** Renamed `bugsink-dev` to `devbugsink`
+
+- New MCP tool prefix: `mcp__devbugsink__*`
+- Changed URL from `http://localhost:8000` to `http://127.0.0.1:8000`
+- **Result:** Still failed after full VS Code restart - server never loaded
+
+**Attempt 2:** Renamed `devbugsink` to `localerrors` (completely different name)
+
+- New MCP tool prefix: `mcp__localerrors__*`
+- Uses completely unrelated name with no shared prefix
+- Based on infra-architect research showing name collision issues
+- **Result:** Still failed after full VS Code restart - server never loaded
+
+**Attempt 3:** Created project-level `.mcp.json` file ✅ **SUCCESS**
+
+- Location: `d:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com\.mcp.json`
+- Contains `localerrors` server configuration
+- Project-level config bypassed the global config loader issue
+- **Result:** ✅ Working! Server loads successfully, 2 projects found
+- Tool prefix: `mcp__localerrors__*`
+
+**Alternative Solutions Researched:**
+
+- Sentry MCP: Not compatible (different API endpoints `/api/canonical/0/` vs `/api/0/`)
+- MCP-Proxy: Could work but requires separate process
+- Project-level `.mcp.json`: Alternative if global config continues to fail
+
+**Status:** ✅ RESOLVED - Project-level `.mcp.json` works successfully
+
+**Root Cause Analysis:**
+Claude Code's global settings.json has an issue loading localhost stdio MCP servers, even with completely distinct names. The exact cause is unknown, but may be related to:
+
+- Multiple servers using the same package (bugsink-mcp)
+- Localhost URL filtering in global config
+- Internal MCP loader bug specific to Windows/localhost combinations
+
+**Working Solution:**
+Use **project-level `.mcp.json`** file instead of global `settings.json` for localhost MCP servers. This bypasses the global config loader issue entirely.
+
+**Key Insights:**
+
+1. Global config fails for localhost servers even with distinct names (`localerrors`)
+2. Project-level `.mcp.json` successfully loads the same configuration
+3. Production HTTPS servers work fine in global config
+4. Both configs can coexist: global for production, project-level for dev
+
+---
+
+### 2026-01-21: Environment Variable Typo (RESOLVED)
+
+**Problem:**
+
+- `bugsink-dev` MCP server fails to start (tools not available)
+- Production `bugsink` MCP works fine
+- User experienced repeated troubleshooting loops without resolution
+
+**Root Cause:**
+Environment variable name mismatch:
+
+- **Package expects:** `BUGSINK_TOKEN`
+- **Configuration had:** `BUGSINK_API_TOKEN`
+
+**Discovery Method:**
+
+- infra-architect subagent examined `d:\gitea\bugsink-mcp\README.md` line 47
+- Found correct variable name in package documentation
+- Production MCP continued working because it was started before config change
+
+**Solution Applied:**
+
+1. Updated `C:\Users\games3\.claude\settings.json`:
+   - Changed `BUGSINK_API_TOKEN` to `BUGSINK_TOKEN` for both `bugsink` and `bugsink-dev`
+   - Removed unused `BUGSINK_ORG_SLUG` environment variable
+
+2. Updated documentation:
+   - `CLAUDE.md` MCP Servers section (lines 307-327)
+   - `docs/BUGSINK-SYNC.md` environment variables (line 66, 108)
+
+3. Required action:
+   - Restart Claude Code to reload MCP servers
+
+**Status:** Fixed - but superseded by server name collision issue above
+
+---
+
+## Correct Configuration
+
+### Required Environment Variables
+
+The bugsink-mcp package requires exactly **TWO** environment variables:
+
+```json
+{
+  "bugsink": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "https://bugsink.projectium.com",
+      "BUGSINK_TOKEN": "<40-char-hex-token>"
+    }
+  },
+  "localerrors": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "http://127.0.0.1:8000",
+      "BUGSINK_TOKEN": "<40-char-hex-token>"
+    }
+  }
+}
+```
+
+**Important:**
+
+- Variable is `BUGSINK_TOKEN`, NOT `BUGSINK_API_TOKEN`
+- `BUGSINK_ORG_SLUG` is NOT used by the package
+- Works with both HTTPS (production) and HTTP (localhost)
+- Use completely distinct name like `localerrors` (not `bugsink-dev` or `devbugsink`) to avoid any name collision
+
+---
+
+## Common Issues
+
+### MCP Server Tools Not Available
+
+**Symptoms:**
+
+- `mcp__localerrors__*` tools return "No such tool available"
+- Production `bugsink` MCP may work while `localerrors` fails
+
+**Possible Causes:**
+
+1. **Wrong environment variable name** (most common)
+   - Check: Variable must be `BUGSINK_TOKEN`, not `BUGSINK_API_TOKEN`
+
+2. **Invalid API token**
+   - Check: Token must be 40-character lowercase hex
+   - Verify: Token created via Django management command
+
+3. **Bugsink instance not accessible**
+   - Test: `curl -s -o /dev/null -w "%{http_code}" http://localhost:8000`
+   - Expected: `302` (redirect) or `200`
+
+4. **MCP server crashed on startup**
+   - Check: Claude Code logs (if available)
+   - Test manually: `BUGSINK_URL=http://localhost:8000 BUGSINK_TOKEN=<token> node d:/gitea/bugsink-mcp/dist/index.js`
+
+**Solution:**
+
+1. Verify correct variable names in settings.json
+2. Restart Claude Code
+3. Test connection: Use `mcp__bugsink__test_connection` tool
+
+---
+
+## Testing MCP Server
+
+### Manual Test
+
+Run the MCP server directly to see error output:
+
+```bash
+# For localhost Bugsink
+cd d:\gitea\bugsink-mcp
+set BUGSINK_URL=http://localhost:8000
+set BUGSINK_TOKEN=a609c2886daa4e1e05f1517074d7779a5fb49056
+node dist/index.js
+```
+
+Expected output:
+
+```
+Bugsink MCP server started
+Connected to: http://localhost:8000
+```
+
+### Test in Claude Code
+
+After restart, verify both MCP servers work:
+
+```typescript
+// Production Bugsink
+mcp__bugsink__test_connection();
+// Expected: "Connection successful: Connected successfully. Found N project(s)."
+
+// Dev Container Bugsink
+mcp__localerrors__test_connection();
+// Expected: "Connection successful: Connected successfully. Found N project(s)."
+```
+
+---
+
+## Creating Bugsink API Tokens
+
+Bugsink 2.0.11 does NOT have a "Settings > API Keys" menu in the UI. Tokens must be created via Django management command.
+
+### For Dev Container (localhost:8000)
+
+```bash
+MSYS_NO_PATHCONV=1 podman exec -e DATABASE_URL=postgresql://bugsink:bugsink_dev_password@postgres:5432/bugsink -e SECRET_KEY=dev-bugsink-secret-key-minimum-50-characters-for-security flyer-crawler-dev sh -c 'cd /opt/bugsink/conf && DJANGO_SETTINGS_MODULE=bugsink_conf PYTHONPATH=/opt/bugsink/conf:/opt/bugsink/lib/python3.10/site-packages /opt/bugsink/bin/python -m django create_auth_token'
+```
+
+### For Production (bugsink.projectium.com via SSH)
+
+```bash
+ssh root@projectium.com "cd /opt/bugsink && bugsink-manage create_auth_token"
+```
+
+Both commands output a 40-character hex token.

+# Bugsink to Gitea Issue Synchronization
+
+This document describes the automated workflow for syncing Bugsink error tracking issues to Gitea tickets.
+
+## Overview
+
+The sync system automatically creates Gitea issues from unresolved Bugsink errors, ensuring all application errors are tracked and assignable.
+
+**Key Points:**
+
+- Runs **only on test/staging server** (not production)
+- Syncs **all 6 Bugsink projects** (including production errors)
+- Creates Gitea issues with full error context
+- Marks synced issues as resolved in Bugsink
+- Uses Redis db 15 for sync state tracking
+
+## Architecture

+
+## Gitea Labels
+
+| Label              | Color              | ID  |
+| ------------------ | ------------------ | --- |
+| bug:frontend       | #e11d48 (Red)      | 8   |
+| bug:backend        | #ea580c (Orange)   | 9   |

+| source:bugsink     | #10b981 (Green)    | 14  |
+
+## Environment Variables
+
+Add these to **test environment only** (`deploy-to-test.yml`):
+
+```bash
+# Bugsink API
+BUGSINK_URL=https://bugsink.projectium.com
+BUGSINK_TOKEN=<create via Django management command - see below>
+
+# Gitea API
+GITEA_URL=https://gitea.projectium.com
+GITEA_API_TOKEN=<personal access token with repo scope>
+GITEA_OWNER=torbo
+GITEA_REPO=flyer-crawler.projectium.com
+
+# Sync Control
+BUGSINK_SYNC_ENABLED=true   # Only set true in test env
+BUGSINK_SYNC_INTERVAL=15    # Minutes between sync runs
+```
+
+## Creating Bugsink API Token
+
+Bugsink 2.0.11 does not have a "Settings > API Keys" UI. Create API tokens via Django management command:
+
+**On Production Server:**
+
+```bash
+sudo su - bugsink
+source venv/bin/activate
+cd ~
+bugsink-manage shell -c "
+from django.contrib.auth import get_user_model
+from rest_framework.authtoken.models import Token
+User = get_user_model()
+user = User.objects.get(email='admin@yourdomain.com')  # Use your admin email
+token, created = Token.objects.get_or_create(user=user)
+print(f'Token: {token.key}')
+"
+exit
+```
+
+This will output a 40-character lowercase hex token.
+
+## Gitea Secrets to Add
+
+Add these secrets in Gitea repository settings (Settings > Secrets):
+
+| Secret Name            | Value                    | Environment |
+| ---------------------- | ------------------------ | ----------- |
+| `BUGSINK_TOKEN`        | Token from command above | Test only   |
+| `GITEA_SYNC_TOKEN`     | Personal access token    | Test only   |
+| `BUGSINK_SYNC_ENABLED` | `true`                   | Test only   |
+
+## Redis Configuration
+
+| Database | Purpose                  |
+| -------- | ------------------------ |
+| 0        | BullMQ production queues |
+| 1        | BullMQ test queues       |
+| 15       | Bugsink sync state       |
+
+**Key Pattern:**
+
+```
+bugsink:synced:{issue_uuid}

+  "project": "flyer-crawler-frontend-test",
+  "title": "[TypeError] t.map is not a function"
+}
+```
+
+## Sync Workflow
+
+1. **Trigger**: Every 15 minutes (or manual via admin API)
+2. **Fetch**: List unresolved issues from all 6 Bugsink projects
+3. **Check**: Skip issues already in Redis sync state

+- [ ] Add env vars to `env.ts` schema
+- [ ] Create BugsinkClient service
+- [ ] Create GiteaClient service
+- [ ] Add Redis db 15 connection
+
+### Phase 2: Sync Logic
+
+- [ ] Create BugsinkSyncService
+- [ ] Add bugsink-sync queue
+- [ ] Add sync worker
+- [ ] Create TypeScript types
+
+### Phase 3: Integration
+
+- [ ] Add admin endpoints

+- [ ] Add Gitea secrets
+- [ ] End-to-end testing
+
+## Troubleshooting
+
+### Sync not running
+
+1. Check `BUGSINK_SYNC_ENABLED` is `true`
+2. Verify worker is running: `GET /api/admin/workers/status`
+3. Check Bull Board: `/api/admin/jobs`
+
+### Duplicate issues created
+
+1. Check Redis db 15 connectivity
+2. Verify sync state keys exist: `redis-cli -n 15 KEYS "bugsink:*"`
+
+### Issues not resolving in Bugsink
+
+1. Verify `BUGSINK_API_TOKEN` has write permissions
+2. Check worker logs for API errors
+
+### Missing stacktrace in Gitea issue
+
+1. Source maps may not be uploaded
+2. Bugsink API may have returned partial data
+3. Check worker logs for fetch errors

+# Dev Container Bugsink Setup
+
+Local Bugsink instance for development - NOT connected to production.
+
+## Quick Reference
+
+| Item         | Value                                                       |
+| ------------ | ----------------------------------------------------------- |
+| UI           | `https://localhost:8443` (nginx proxy from 8000)            |
+| Credentials  | `admin@localhost` / `admin`                                 |
+| Projects     | Backend (Dev) = Project ID 1, Frontend (Dev) = Project ID 2 |
+| Backend DSN  | `SENTRY_DSN=http://<key>@localhost:8000/1`                  |
+| Frontend DSN | `VITE_SENTRY_DSN=http://<key>@localhost:8000/2`             |
+
+## Configuration Files
+
+| File              | Purpose                                                           |
+| ----------------- | ----------------------------------------------------------------- |
+| `compose.dev.yml` | Initial DSNs using `127.0.0.1:8000` (container startup)           |
+| `.env.local`      | **OVERRIDES** compose.dev.yml with `localhost:8000` (app runtime) |
+
+**CRITICAL**: `.env.local` takes precedence over `compose.dev.yml` environment variables.
+
+## Why localhost vs 127.0.0.1?
+
+The `.env.local` file uses `localhost` while `compose.dev.yml` uses `127.0.0.1`. Both work in practice - `localhost` was chosen when `.env.local` was created separately.
+
+## HTTPS Setup
+
+- Self-signed certificates auto-generated with mkcert on container startup
+- CSRF Protection: Django configured with `SECURE_PROXY_SSL_HEADER` to trust `X-Forwarded-Proto` from nginx
+- HTTPS is for UI access only - Sentry SDK uses HTTP directly
+
+## Isolation Benefits
+
+- Dev errors stay local, don't pollute production/test dashboards
+- No Gitea secrets needed - everything self-contained
+- Independent testing of error tracking without affecting metrics
+
+## Accessing Errors
+
+### Via Browser
+
+1. Open `https://localhost:8443`
+2. Login with credentials above
+3. Navigate to Issues to view captured errors
+
+### Via MCP (bugsink-dev)
+
+Configure in `.claude/mcp.json`:
+
+```json
+{
+  "bugsink-dev": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "http://localhost:8000",
+      "BUGSINK_API_TOKEN": "<token-from-local-bugsink>",
+      "BUGSINK_ORG_SLUG": "sentry"
+    }
+  }
+}
+```
+
+**Get auth token**:
+
+API tokens must be created via Django management command (Bugsink 2.0.11 does not have a "Settings > API Keys" UI):
+
+```bash
+podman exec flyer-crawler-dev sh -c 'cd /opt/bugsink/conf && \
+  DATABASE_URL=postgresql://bugsink:bugsink_dev_password@postgres:5432/bugsink \
+  SECRET_KEY=dev-bugsink-secret-key-minimum-50-characters-for-security \
+  DJANGO_SETTINGS_MODULE=bugsink_conf \
+  PYTHONPATH=/opt/bugsink/conf:/opt/bugsink/lib/python3.10/site-packages \
+  /opt/bugsink/bin/python -m django create_auth_token'
+```
+
+This will output a 40-character lowercase hex token. Copy it to your MCP configuration.
+
+**MCP Tools**: Use `mcp__bugsink-dev__*` tools (not `mcp__bugsink__*` which connects to production).

+# Flyer URL Configuration
+
+## Overview
+
+Flyer image and icon URLs are environment-specific to ensure they point to the correct server for each deployment. Images are served as static files by NGINX from the `/flyer-images/` path with 7-day browser caching enabled.
+
+## Environment-Specific URLs
+
+| Environment   | Base URL                                    | Example                                                                    |
+| ------------- | ------------------------------------------- | -------------------------------------------------------------------------- |
+| Dev Container | `https://127.0.0.1`                         | `https://127.0.0.1/flyer-images/safeway-flyer.jpg`                         |
+| Test          | `https://flyer-crawler-test.projectium.com` | `https://flyer-crawler-test.projectium.com/flyer-images/safeway-flyer.jpg` |
+| Production    | `https://flyer-crawler.projectium.com`      | `https://flyer-crawler.projectium.com/flyer-images/safeway-flyer.jpg`      |
+
+**Note:** The dev container accepts connections to **both** `https://localhost/` and `https://127.0.0.1/` thanks to the SSL certificate and NGINX configuration. See [SSL Certificate Configuration](#ssl-certificate-configuration-dev-container) below.
+
+## SSL Certificate Configuration (Dev Container)
+
+The dev container uses self-signed certificates generated by [mkcert](https://github.com/FiloSottile/mkcert) to enable HTTPS locally. This configuration solves a common mixed-origin SSL issue.
+
+### The Problem
+
+When users access the site via `https://localhost/` but image URLs in the database use `https://127.0.0.1/...`, browsers treat these as different origins. This causes `ERR_CERT_AUTHORITY_INVALID` errors when loading images, even though both hostnames point to the same server.
+
+### The Solution
+
+1. **Certificate Generation** (`Dockerfile.dev`):
+
+   ```bash
+   mkcert localhost 127.0.0.1 ::1
+   ```
+
+   This creates a certificate with Subject Alternative Names (SANs) for all three hostnames.
+
+2. **NGINX Configuration** (`docker/nginx/dev.conf`):
+
+   ```nginx
+   server_name localhost 127.0.0.1;
+   ```
+
+   NGINX accepts requests to both hostnames using the same SSL certificate.
+
+### How It Works
+
+| Component            | Configuration                                        |
+| -------------------- | ---------------------------------------------------- |
+| SSL Certificate SANs | `localhost`, `127.0.0.1`, `::1`                      |
+| NGINX `server_name`  | `localhost 127.0.0.1`                                |
+| Seed Script URLs     | Uses `https://127.0.0.1` (works with DB constraints) |
+| User Access          | Either `https://localhost/` or `https://127.0.0.1/`  |
+
+### Why This Matters
+
+- **Database Constraints**: The `flyers` table has CHECK constraints requiring URLs to start with `http://` or `https://`. Relative URLs are not allowed.
+- **Consistent Behavior**: Users can access the site using either hostname without SSL warnings.
+- **Same Certificate**: Both hostnames use the same self-signed certificate, eliminating mixed-content errors.
+
+### Verifying the Configuration
+
+```bash
+# Check certificate SANs
+podman exec flyer-crawler-dev openssl x509 -in /app/certs/localhost.crt -text -noout | grep -A1 "Subject Alternative Name"
+
+# Expected output:
+# X509v3 Subject Alternative Name:
+#     DNS:localhost, IP Address:127.0.0.1, IP Address:0:0:0:0:0:0:0:1
+
+# Test both hostnames respond
+curl -k https://localhost/health
+curl -k https://127.0.0.1/health
+```
+
+### Troubleshooting SSL Issues
+
+If you encounter `ERR_CERT_AUTHORITY_INVALID`:
+
+1. **Check NGINX is running**: `podman exec flyer-crawler-dev nginx -t`
+2. **Verify certificate exists**: `podman exec flyer-crawler-dev ls -la /app/certs/`
+3. **Ensure both hostnames are in server_name**: Check `/etc/nginx/sites-available/default`
+4. **Rebuild container if needed**: The certificate is generated at build time
+
+### Permanent Fix: Install CA Certificate (Recommended)
+
+To permanently eliminate SSL certificate warnings, install the mkcert CA certificate on your system. This is optional but provides a better development experience.
+
+The CA certificate is located at `certs/mkcert-ca.crt` in the project root. See [`certs/README.md`](../certs/README.md) for platform-specific installation instructions (Windows, macOS, Linux, Firefox).
+
+After installation:
+
+- Your browser will trust all mkcert certificates without warnings
+- Both `https://localhost/` and `https://127.0.0.1/` will work without SSL errors
+- Flyer images will load without `ERR_CERT_AUTHORITY_INVALID` errors
+
+See also: [Debugging Guide - SSL Issues](development/DEBUGGING.md#ssl-certificate-issues)
+
+## NGINX Static File Serving
+
+All environments serve flyer images as static files with browser caching:
+
+```nginx
+# Serve flyer images from static storage (7-day cache)
+location /flyer-images/ {
+    alias /path/to/flyer-images/;
+    expires 7d;
+    add_header Cache-Control "public, immutable";
+}

+
+### Directory Paths by Environment
+
+| Environment   | NGINX Alias Path                                           |
+| ------------- | ---------------------------------------------------------- |
+| Dev Container | `/app/public/flyer-images/`                                |
+| Test          | `/var/www/flyer-crawler-test.projectium.com/flyer-images/` |
+| Production    | `/var/www/flyer-crawler.projectium.com/flyer-images/`      |
+
+## Configuration
+
+### Environment Variable
+
+Set `FLYER_BASE_URL` in your environment configuration:
+
+```bash
+# Dev container (.env)
+FLYER_BASE_URL=https://localhost
+
+# Test environment
+FLYER_BASE_URL=https://flyer-crawler-test.projectium.com
+
+# Production
+FLYER_BASE_URL=https://flyer-crawler.projectium.com
+```
+
+### Seed Script
+
+The seed script ([src/db/seed.ts](../src/db/seed.ts)) automatically uses the correct base URL based on:
+
+1. `FLYER_BASE_URL` environment variable (if set)
+2. `NODE_ENV` value:
+   - `production` → `https://flyer-crawler.projectium.com`
+   - `test` → `https://flyer-crawler-test.projectium.com`
+   - Default → `https://localhost`
+
+The seed script also copies test images from `src/tests/assets/` to `public/flyer-images/`:
+
+- `test-flyer-image.jpg` - Sample flyer image
+- `test-flyer-icon.png` - Sample 64x64 icon
+
+## Updating Existing Data
+
+If you need to update existing flyer URLs in the database, use the provided SQL script:
+
+### Dev Container
+
+```bash
+# Connect to dev database
+podman exec -it flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev
+
+# Run the update (dev container uses HTTPS with self-signed certs)
+UPDATE flyers
+SET
+    image_url = REPLACE(image_url, 'example.com', 'localhost'),
+    icon_url = REPLACE(icon_url, 'example.com', 'localhost')
+WHERE
+    image_url LIKE '%example.com%'
+    OR icon_url LIKE '%example.com%';
+
+# Verify
+SELECT flyer_id, image_url, icon_url FROM flyers;
+```
+
+### Test Environment
+
+```bash
+# Via SSH
+ssh root@projectium.com "psql -U flyer_crawler_test -d flyer-crawler-test -c \"
+UPDATE flyers
+SET
+    image_url = REPLACE(image_url, 'example.com', 'flyer-crawler-test.projectium.com'),
+    icon_url = REPLACE(icon_url, 'example.com', 'flyer-crawler-test.projectium.com')
+WHERE
+    image_url LIKE '%example.com%'
+    OR icon_url LIKE '%example.com%';
+\""
+```
+
+### Production
+
+```bash
+# Via SSH
+ssh root@projectium.com "psql -U flyer_crawler_prod -d flyer-crawler-prod -c \"
+UPDATE flyers
+SET
+    image_url = REPLACE(image_url, 'example.com', 'flyer-crawler.projectium.com'),
+    icon_url = REPLACE(icon_url, 'example.com', 'flyer-crawler.projectium.com')
+WHERE
+    image_url LIKE '%example.com%'
+    OR icon_url LIKE '%example.com%';
+\""
+```
+
+## Test Data Updates
+
+### Test Helper Function
+
+A helper function `getFlyerBaseUrl()` is available in [src/tests/utils/testHelpers.ts](../src/tests/utils/testHelpers.ts) that automatically detects the correct base URL for tests:
+
+```typescript
+export const getFlyerBaseUrl = (): string => {
+  if (process.env.FLYER_BASE_URL) {
+    return process.env.FLYER_BASE_URL;
+  }
+
+  // Check if we're in dev container (DB_HOST=postgres is typical indicator)
+  // Use 'localhost' instead of '127.0.0.1' to match the hostname users access
+  // This avoids SSL certificate mixed-origin issues in browsers
+  if (process.env.DB_HOST === 'postgres' || process.env.DB_HOST === '127.0.0.1') {
+    return 'https://localhost';
+  }
+
+  if (process.env.NODE_ENV === 'production') {
+    return 'https://flyer-crawler.projectium.com';
+  }
+
+  if (process.env.NODE_ENV === 'test') {
+    return 'https://flyer-crawler-test.projectium.com';
+  }
+
+  // Default for unit tests
+  return 'https://example.com';
+};
+```
+
+### Updated Test Files
+
+The following test files now use `getFlyerBaseUrl()` for environment-aware URL generation:
+
+- [src/db/seed.ts](../src/db/seed.ts) - Main seed script (uses `FLYER_BASE_URL`)
+- [src/tests/utils/testHelpers.ts](../src/tests/utils/testHelpers.ts) - `getFlyerBaseUrl()` helper function
+- [src/hooks/useDataExtraction.test.ts](../src/hooks/useDataExtraction.test.ts) - Mock flyer factory
+- [src/schemas/flyer.schemas.test.ts](../src/schemas/flyer.schemas.test.ts) - Schema validation tests
+- [src/services/flyerProcessingService.server.test.ts](../src/services/flyerProcessingService.server.test.ts) - Processing service tests
+- [src/tests/integration/flyer-processing.integration.test.ts](../src/tests/integration/flyer-processing.integration.test.ts) - Integration tests
+
+This approach ensures tests work correctly in all environments (dev container, CI/CD, local development, test, production).
+

+# Production Deployment Checklist: Extended Logstash Configuration
+
+**Important**: This checklist follows a **inspect-first, then-modify** approach. Each step first checks the current state before making changes.
+
+---
+
+## Phase 1: Pre-Deployment Inspection
+
+### Step 1.1: Verify Logstash Status
+
+```bash
+ssh root@projectium.com
+systemctl status logstash
+curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.events'
+```
+
+**Record current state:**
+
+- Status: [active/inactive]
+- Events processed: [number]
+- Memory usage: [amount]
+
+**Expected**: Logstash should be active and processing PostgreSQL logs from ADR-050.
+
+---
+
+### Step 1.2: Inspect Existing Configuration Files
+
+```bash
+# List all configuration files
+ls -alF /etc/logstash/conf.d/
+
+# Check existing backups (if any)
+ls -lh /etc/logstash/conf.d/*.backup-* 2>/dev/null || echo "No backups found"
+
+# View current configuration
+cat /etc/logstash/conf.d/bugsink.conf
+```
+
+**Record current state:**
+
+- Configuration files present: [list]
+- Existing backups: [list or "none"]
+- Current config size: [bytes]
+
+**Questions to answer:**
+
+- ✅ Is there an existing `bugsink.conf`?
+- ✅ Are there any existing backups?
+- ✅ What inputs/filters/outputs are currently configured?
+
+---
+
+### Step 1.3: Inspect Log Output Directory
+
+```bash
+# Check if directory exists
+ls -ld /var/log/logstash 2>/dev/null || echo "Directory does not exist"
+
+# If exists, check contents
+ls -alF /var/log/logstash/
+
+# Check ownership and permissions
+ls -ld /var/log/logstash
+```
+
+**Record current state:**
+
+- Directory exists: [yes/no]
+- Current ownership: [user:group]
+- Current permissions: [drwx------]
+- Existing files: [list]
+
+**Questions to answer:**
+
+- ✅ Does `/var/log/logstash/` already exist?
+- ✅ What files are currently in it?
+- ✅ Are these Logstash's own logs or our operational logs?
+
+---
+
+### Step 1.4: Check Logrotate Configuration
+
+```bash
+# Check if logrotate config exists
+cat /etc/logrotate.d/logstash 2>/dev/null || echo "No logrotate config found"
+
+# List all logrotate configs
+ls -lh /etc/logrotate.d/ | grep logstash
+```
+
+**Record current state:**
+
+- Logrotate config exists: [yes/no]
+- Current rotation policy: [daily/weekly/none]
+
+---
+
+### Step 1.5: Check Logstash User Groups
+
+```bash
+# Check current group membership
+groups logstash
+
+# Verify which groups have access to required logs
+ls -l /home/gitea-runner/.pm2/logs/*.log | head -3
+ls -l /var/log/redis/redis-server.log
+ls -l /var/log/nginx/access.log
+ls -l /var/log/nginx/error.log
+```
+
+**Record current state:**
+
+- Logstash groups: [list]
+- PM2 log file group: [group]
+- Redis log file group: [group]
+- NGINX log file group: [group]
+
+**Questions to answer:**
+
+- ✅ Is logstash already in the `adm` group?
+- ✅ Is logstash already in the `postgres` group?
+- ✅ Can logstash currently read PM2 logs?
+
+---
+
+### Step 1.6: Test Log File Access (Current State)
+
+```bash
+# Test PM2 worker logs
+sudo -u logstash cat /home/gitea-runner/.pm2/logs/flyer-crawler-worker-*.log | head -5 2>&1
+
+# Test PM2 analytics worker logs
+sudo -u logstash cat /home/gitea-runner/.pm2/logs/flyer-crawler-analytics-worker-*.log | head -5 2>&1
+
+# Test Redis logs
+sudo -u logstash cat /var/log/redis/redis-server.log | head -5 2>&1
+
+# Test NGINX access logs
+sudo -u logstash cat /var/log/nginx/access.log | head -5 2>&1
+
+# Test NGINX error logs
+sudo -u logstash cat /var/log/nginx/error.log | head -5 2>&1
+```
+
+**Record current state:**
+
+- PM2 worker logs accessible: [yes/no/error]
+- PM2 analytics logs accessible: [yes/no/error]
+- Redis logs accessible: [yes/no/error]
+- NGINX access logs accessible: [yes/no/error]
+- NGINX error logs accessible: [yes/no/error]
+
+**If any fail**: Note the specific error message (permission denied, file not found, etc.)
+
+---
+
+### Step 1.7: Check PM2 Log File Locations
+
+```bash
+# List all PM2 log files
+ls -lh /home/gitea-runner/.pm2/logs/
+
+# Check for production and test worker logs
+ls -lh /home/gitea-runner/.pm2/logs/ | grep -E "(flyer-crawler-worker|flyer-crawler-analytics-worker)"
+```
+
+**Record current state:**
+
+- Production worker logs present: [yes/no]
+- Test worker logs present: [yes/no]
+- Analytics worker logs present: [yes/no]
+- File naming pattern: [describe pattern]
+
+**Questions to answer:**
+
+- ✅ Do the log file paths match what's in the new Logstash config?
+- ✅ Are there separate logs for production vs test environments?
+
+---
+
+### Step 1.8: Check Disk Space
+
+```bash
+# Check available disk space
+df -h /var/log/
+
+# Check current size of Logstash logs
+du -sh /var/log/logstash/
+
+# Check size of PM2 logs
+du -sh /home/gitea-runner/.pm2/logs/
+```
+
+**Record current state:**
+
+- Available space on `/var/log`: [amount]
+- Current Logstash log size: [amount]
+- Current PM2 log size: [amount]
+
+**Risk assessment:**
+
+- ✅ Is there sufficient space for 30 days of rotated logs?
+- ✅ Estimate: ~100MB/day for new operational logs = ~3GB for 30 days
+
+---
+
+### Step 1.9: Review Bugsink Projects
+
+```bash
+# Check if Bugsink projects 5 and 6 exist
+# (This requires accessing Bugsink UI or API)
+echo "Manual check: Navigate to https://bugsink.projectium.com"
+echo "Verify project IDs 5 and 6 exist and their names/DSNs"
+```
+
+**Record current state:**
+
+- Project 5 exists: [yes/no]
+- Project 5 name: [name]
+- Project 6 exists: [yes/no]
+- Project 6 name: [name]
+
+**Questions to answer:**
+
+- ✅ Do the project IDs in the new config match actual Bugsink projects?
+- ✅ Are DSNs correct?
+
+---
+
+## Phase 2: Make Deployment Decisions
+
+Based on Phase 1 inspection, answer these questions:
+
+1. **Backup needed?**
+   - Current config exists: [yes/no]
+   - Decision: [create backup / no backup needed]
+
+2. **Directory creation needed?**
+   - `/var/log/logstash/` exists with correct permissions: [yes/no]
+   - Decision: [create directory / fix permissions / no action needed]
+
+3. **Logrotate config needed?**
+   - Config exists: [yes/no]
+   - Decision: [create config / update config / no action needed]
+
+4. **Group membership needed?**
+   - Logstash already in `adm` group: [yes/no]
+   - Decision: [add to group / already member]
+
+5. **Log file access issues?**
+   - Any files inaccessible: [list files]
+   - Decision: [fix permissions / fix group membership / no action needed]
+
+---
+
+## Phase 3: Execute Deployment
+
+### Step 3.1: Create Configuration Backup
+
+**Only if**: Configuration file exists and no recent backup.
+
+```bash
+# Create timestamped backup
+sudo cp /etc/logstash/conf.d/bugsink.conf \
+  /etc/logstash/conf.d/bugsink.conf.backup-$(date +%Y%m%d-%H%M%S)
+
+# Verify backup
+ls -lh /etc/logstash/conf.d/*.backup-*
+```
+
+**Confirmation**: ✅ Backup file created with timestamp.
+
+---
+
+### Step 3.2: Handle Log Output Directory
+
+**If directory doesn't exist:**
+
+```bash
+sudo mkdir -p /var/log/logstash-operational
+sudo chown logstash:logstash /var/log/logstash-operational
+sudo chmod 755 /var/log/logstash-operational
+```
+
+**If directory exists but has wrong permissions:**
+
+```bash
+sudo chown logstash:logstash /var/log/logstash
+sudo chmod 755 /var/log/logstash
+```
+
+**Note**: The existing `/var/log/logstash/` contains Logstash's own operational logs (logstash-plain.log, etc.). You have two options:
+
+**Option A**: Use a separate directory for our operational logs (recommended):
+
+- Directory: `/var/log/logstash-operational/`
+- Update config to use this path instead
+
+**Option B**: Share the directory (requires careful logrotate config):
+
+- Keep using `/var/log/logstash/`
+- Ensure logrotate doesn't rotate our custom logs the same way as Logstash's own logs
+
+**Decision**: [Choose Option A or B]
+
+**Verification:**
+
+```bash
+ls -ld /var/log/logstash-operational  # or /var/log/logstash
+```
+
+**Confirmation**: ✅ Directory exists with `drwxr-xr-x logstash logstash`.
+
+---
+
+### Step 3.3: Configure Logrotate
+
+**Only if**: Logrotate config doesn't exist or needs updating.
+
+**For Option A (separate directory):**
+
+```bash
+sudo tee /etc/logrotate.d/logstash-operational <<'EOF'
+/var/log/logstash-operational/*.log {
+    daily
+    rotate 30
+    compress
+    delaycompress
+    missingok
+    notifempty
+    create 0644 logstash logstash
+    sharedscripts
+    postrotate
+        # No reload needed - Logstash handles rotation automatically
+    endscript
+}
+EOF
+```
+
+**For Option B (shared directory):**
+
+```bash
+sudo tee /etc/logrotate.d/logstash-operational <<'EOF'
+/var/log/logstash/pm2-workers-*.log
+/var/log/logstash/redis-operational-*.log
+/var/log/logstash/nginx-access-*.log {
+    daily
+    rotate 30
+    compress
+    delaycompress
+    missingok
+    notifempty
+    create 0644 logstash logstash
+    sharedscripts
+    postrotate
+        # No reload needed - Logstash handles rotation automatically
+    endscript
+}
+EOF
+```
+
+**Verify configuration:**
+
+```bash
+sudo logrotate -d /etc/logrotate.d/logstash-operational
+cat /etc/logrotate.d/logstash-operational
+```
+
+**Confirmation**: ✅ Logrotate config created, syntax check passes.
+
+---
+
+### Step 3.4: Grant Logstash Permissions
+
+**Only if**: Logstash not already in `adm` group.
+
+```bash
+# Add logstash to adm group (for NGINX and system logs)
+sudo usermod -a -G adm logstash
+
+# Verify group membership
+groups logstash
+```
+
+**Expected output**: `logstash : logstash adm postgres`
+
+**Confirmation**: ✅ Logstash user is in required groups.
+
+---
+
+### Step 3.5: Verify Log File Access (Post-Permission Changes)
+
+**Only if**: Previous access tests failed.
+
+```bash
+# Re-test log file access
+sudo -u logstash cat /home/gitea-runner/.pm2/logs/flyer-crawler-worker-*.log | head -5
+sudo -u logstash cat /home/gitea-runner/.pm2/logs/flyer-crawler-analytics-worker-*.log | head -5
+sudo -u logstash cat /var/log/redis/redis-server.log | head -5
+sudo -u logstash cat /var/log/nginx/access.log | head -5
+sudo -u logstash cat /var/log/nginx/error.log | head -5
+```
+
+**Confirmation**: ✅ All log files now readable without errors.
+
+---
+
+### Step 3.6: Update Logstash Configuration
+
+**Important**: Before pasting, adjust the file output paths based on your directory decision.
+
+```bash
+# Open configuration file
+sudo nano /etc/logstash/conf.d/bugsink.conf
+```
+
+**Paste the complete configuration from `docs/BARE-METAL-SETUP.md`.**
+
+**If using Option A (separate directory)**, update these lines in the config:
+
+```ruby
+# Change this:
+path => "/var/log/logstash/pm2-workers-%{+YYYY-MM-dd}.log"
+
+# To this:
+path => "/var/log/logstash-operational/pm2-workers-%{+YYYY-MM-dd}.log"
+
+# (Repeat for redis-operational and nginx-access file outputs)
+```
+
+**Save and exit**: Ctrl+X, Y, Enter
+
+---
+
+### Step 3.7: Test Configuration Syntax
+
+```bash
+# Test for syntax errors
+sudo /usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/bugsink.conf
+```
+
+**Expected output**: `Configuration OK`
+
+**If errors:**
+
+1. Review error message for line number
+2. Check for missing braces, quotes, commas
+3. Verify file paths match your directory decision
+4. Compare against documentation
+
+**Confirmation**: ✅ Configuration syntax is valid.
+
+---
+
+### Step 3.8: Restart Logstash Service
+
+```bash
+# Restart Logstash
+sudo systemctl restart logstash
+
+# Check service started successfully
+sudo systemctl status logstash
+
+# Wait for initialization
+sleep 30
+
+# Check for startup errors
+sudo journalctl -u logstash -n 100 --no-pager | grep -i error
+```
+
+**Expected**:
+
+- Status: `active (running)`
+- No critical errors (warnings about missing files are OK initially)
+
+**Confirmation**: ✅ Logstash restarted successfully.
+
+---
+
+## Phase 4: Post-Deployment Verification
+
+### Step 4.1: Verify Pipeline Processing
+
+```bash
+# Check pipeline stats - events should be increasing
+curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.events'
+
+# Check input plugins
+curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.plugins.inputs'
+
+# Check for grok failures
+curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.plugins.filters[] | select(.name == "grok") | {name, events_in: .events.in, events_out: .events.out, failures}'
+```
+
+**Expected**:
+
+- `events.in` and `events.out` are increasing
+- Input plugins show files being read
+- Grok failures < 1% of events
+
+**Confirmation**: ✅ Pipeline processing events from multiple sources.
+
+---
+
+### Step 4.2: Verify File Outputs Created
+
+```bash
+# Wait a few minutes for log generation
+sleep 120
+
+# Check files were created
+ls -lh /var/log/logstash-operational/  # or /var/log/logstash/
+
+# View sample logs
+tail -20 /var/log/logstash-operational/pm2-workers-$(date +%Y-%m-%d).log
+tail -20 /var/log/logstash-operational/redis-operational-$(date +%Y-%m-%d).log
+tail -20 /var/log/logstash-operational/nginx-access-$(date +%Y-%m-%d).log
+```
+
+**Expected**:
+
+- Files exist with today's date
+- Files contain JSON-formatted log entries
+- Timestamps are recent
+
+**Confirmation**: ✅ Operational logs being written successfully.
+
+---
+
+### Step 4.3: Test Error Forwarding to Bugsink
+
+```bash
+# Check HTTP output stats (Bugsink forwarding)
+curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.plugins.outputs[] | select(.name == "http") | {name, events_in: .events.in, events_out: .events.out}'
+```
+
+**Manual check**:
+
+1. Navigate to: https://bugsink.projectium.com
+2. Check Project 5 (production infrastructure) for recent events
+3. Check Project 6 (test infrastructure) for recent events
+
+**Confirmation**: ✅ Errors forwarded to correct Bugsink projects.
+
+---
+
+### Step 4.4: Monitor Logstash Performance
+
+```bash
+# Check memory usage
+ps aux | grep logstash | grep -v grep
+
+# Check disk usage
+du -sh /var/log/logstash-operational/
+
+# Monitor in real-time (Ctrl+C to exit)
+sudo journalctl -u logstash -f
+```
+
+**Expected**:
+
+- Memory usage < 1.5GB (with 1GB heap)
+- Disk usage reasonable (< 100MB for first day)
+- No repeated errors
+
+**Confirmation**: ✅ Performance is stable.
+
+---
+
+### Step 4.5: Verify Environment Detection
+
+```bash
+# Check recent logs for environment tags
+sudo journalctl -u logstash -n 500 | grep -E "(production|test)" | tail -20
+
+# Check file outputs for correct tagging
+grep -o '"environment":"[^"]*"' /var/log/logstash-operational/pm2-workers-$(date +%Y-%m-%d).log | sort | uniq -c
+```
+
+**Expected**:
+
+- Production worker logs tagged as "production"
+- Test worker logs tagged as "test"
+
+**Confirmation**: ✅ Environment detection working correctly.
+
+---
+
+### Step 4.6: Document Deployment
+
+```bash
+# Record deployment
+echo "Extended Logstash Configuration deployed on $(date)" | sudo tee -a /var/log/deployments.log
+
+# Record configuration version
+sudo ls -lh /etc/logstash/conf.d/bugsink.conf
+```
+
+**Confirmation**: ✅ Deployment documented.
+
+---
+
+## Phase 5: 24-Hour Monitoring Plan
+
+Monitor these metrics over the next 24 hours:
+
+**Every 4 hours:**
+
+1. **Service health**: `systemctl status logstash`
+2. **Disk usage**: `du -sh /var/log/logstash-operational/`
+3. **Memory usage**: `ps aux | grep logstash | grep -v grep`
+
+**Every 12 hours:**
+
+1. **Error rates**: Check Bugsink projects 5 and 6
+2. **Log file growth**: `ls -lh /var/log/logstash-operational/`
+3. **Pipeline stats**: `curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.events'`
+
+---
+
+## Rollback Procedure
+
+**If issues occur:**
+
+```bash
+# Stop Logstash
+sudo systemctl stop logstash
+
+# Find latest backup
+ls -lt /etc/logstash/conf.d/*.backup-* | head -1
+
+# Restore backup (replace TIMESTAMP with actual timestamp)
+sudo cp /etc/logstash/conf.d/bugsink.conf.backup-TIMESTAMP \
+  /etc/logstash/conf.d/bugsink.conf
+
+# Test restored config
+sudo /usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/bugsink.conf
+
+# Restart Logstash
+sudo systemctl start logstash
+
+# Verify status
+systemctl status logstash
+```
+
+---
+
+## Quick Health Check
+
+Run this anytime to verify deployment health:
+
+```bash
+# One-line health check
+systemctl is-active logstash && \
+  echo "Service: OK" && \
+  ls /var/log/logstash-operational/*.log &>/dev/null && \
+  echo "Logs: OK" && \
+  curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq -e '.pipelines.main.events.in > 0' &>/dev/null && \
+  echo "Processing: OK"
+```
+
+Expected output:
+
+```
+active
+Service: OK
+Logs: OK
+Processing: OK
+```

+# PostgreSQL MCP Server Setup
+
+This document describes the configuration and troubleshooting for the PostgreSQL MCP server integration with Claude Code.
+
+## Status
+
+✅ **WORKING** - Successfully configured and tested on 2026-01-22
+
+- **Server Name**: `devdb`
+- **Database**: `flyer_crawler_dev` (68 tables)
+- **Connection**: Verified working
+- **Tool Prefix**: `mcp__devdb__*`
+- **Configuration**: Project-level `.mcp.json`
+
+## Overview
+
+The PostgreSQL MCP server (`@modelcontextprotocol/server-postgres`) provides database query capabilities directly from Claude Code, enabling:
+
+- Running SQL queries against the development database
+- Exploring database schema and tables
+- Testing queries before implementation
+- Debugging data issues
+
+## Configuration
+
+### Project-Level Configuration (Recommended)
+
+The PostgreSQL MCP server is configured in the project-level `.mcp.json` file:
+
+```json
+{
+  "mcpServers": {
+    "devdb": {
+      "command": "D:\\nodejs\\npx.cmd",
+      "args": [
+        "-y",
+        "@modelcontextprotocol/server-postgres",
+        "postgresql://postgres:postgres@127.0.0.1:5432/flyer_crawler_dev"
+      ]
+    }
+  }
+}
+```
+
+**Key Configuration Details:**
+
+| Parameter   | Value                                   | Notes                                   |
+| ----------- | --------------------------------------- | --------------------------------------- |
+| Server Name | `devdb`                                 | Distinct name to avoid collision issues |
+| Package     | `@modelcontextprotocol/server-postgres` | Official MCP PostgreSQL server          |
+| Host        | `127.0.0.1`                             | Use IP address, not `localhost`         |
+| Port        | `5432`                                  | Default PostgreSQL port                 |
+| Database    | `flyer_crawler_dev`                     | Development database name               |
+| User        | `postgres`                              | Default superuser for dev               |
+| Password    | `postgres`                              | Default password for dev                |
+
+### Why Project-Level Configuration?
+
+Based on troubleshooting experience with other MCP servers (documented in `BUGSINK-MCP-TROUBLESHOOTING.md`), **localhost MCP servers work more reliably in project-level `.mcp.json`** than in global `settings.json`.
+
+Issues observed with global configuration:
+
+- MCP servers silently not loading
+- No error messages in logs
+- Tools not appearing in available tool list
+
+Project-level configuration bypasses these issues entirely.
+
+### Connection String Format
+
+```
+postgresql://[user]:[password]@[host]:[port]/[database]
+```
+
+Examples:
+
+```
+# Development (local container)
+postgresql://postgres:postgres@127.0.0.1:5432/flyer_crawler_dev
+
+# Test database (if needed)
+postgresql://flyer_crawler_test:password@127.0.0.1:5432/flyer_crawler_test
+```
+
+## Available Tools
+
+Once configured, the following tools become available (prefix `mcp__devdb__`):
+
+| Tool    | Description                            |
+| ------- | -------------------------------------- |
+| `query` | Execute SQL queries and return results |
+
+## Usage Examples
+
+### Basic Query
+
+```typescript
+// List all tables
+mcp__devdb__query("SELECT tablename FROM pg_tables WHERE schemaname = 'public'");
+
+// Count records in a table
+mcp__devdb__query('SELECT COUNT(*) FROM flyers');
+
+// Check table structure
+mcp__devdb__query(
+  "SELECT column_name, data_type FROM information_schema.columns WHERE table_name = 'flyers'",
+);
+```
+
+### Debugging Data Issues
+
+```typescript
+// Find recent flyers
+mcp__devdb__query('SELECT id, name, created_at FROM flyers ORDER BY created_at DESC LIMIT 10');
+
+// Check job queue status
+mcp__devdb__query('SELECT state, COUNT(*) FROM bullmq_jobs GROUP BY state');
+
+// Verify user data
+mcp__devdb__query("SELECT id, email, created_at FROM users WHERE email LIKE '%test%'");
+```
+
+## Prerequisites
+
+### 1. PostgreSQL Container Running
+
+The PostgreSQL container must be running and healthy:
+
+```bash
+# Check container status
+podman ps | grep flyer-crawler-postgres
+
+# Expected output shows "healthy" status
+# flyer-crawler-postgres ... Up N hours (healthy) ...
+```
+
+### 2. Port Accessible from Host
+
+PostgreSQL port 5432 must be mapped to the host:
+
+```bash
+# Verify port mapping
+podman port flyer-crawler-postgres
+# Expected: 5432/tcp -> 0.0.0.0:5432
+```
+
+### 3. Database Exists
+
+Verify the database exists:
+
+```bash
+podman exec flyer-crawler-postgres psql -U postgres -c "\l" | grep flyer_crawler_dev
+```
+
+## Troubleshooting
+
+### Tools Not Available
+
+**Symptoms:**
+
+- `mcp__devdb__*` tools not in available tool list
+- No error messages displayed
+
+**Solutions:**
+
+1. **Restart Claude Code** - MCP config changes require restart
+2. **Check container status** - Ensure PostgreSQL container is running
+3. **Verify port mapping** - Confirm port 5432 is accessible
+4. **Test connection manually**:
+   ```bash
+   podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "SELECT 1"
+   ```
+
+### Connection Refused
+
+**Symptoms:**
+
+- Connection error when using tools
+- "Connection refused" in error message
+
+**Solutions:**
+
+1. **Check container health**:
+
+   ```bash
+   podman ps | grep flyer-crawler-postgres
+   ```
+
+2. **Restart the container**:
+
+   ```bash
+   podman restart flyer-crawler-postgres
+   ```
+
+3. **Check for port conflicts**:
+   ```bash
+   netstat -an | findstr 5432
+   ```
+
+### Authentication Failed
+
+**Symptoms:**
+
+- "password authentication failed" error
+
+**Solutions:**
+
+1. **Verify credentials** in container environment:
+
+   ```bash
+   podman exec flyer-crawler-dev env | grep DB_
+   ```
+
+2. **Check PostgreSQL users**:
+
+   ```bash
+   podman exec flyer-crawler-postgres psql -U postgres -c "\du"
+   ```
+
+3. **Update connection string** in `.mcp.json` if credentials differ
+
+### Database Does Not Exist
+
+**Symptoms:**
+
+- "database does not exist" error
+
+**Solutions:**
+
+1. **List available databases**:
+
+   ```bash
+   podman exec flyer-crawler-postgres psql -U postgres -c "\l"
+   ```
+
+2. **Create database if missing**:
+   ```bash
+   podman exec flyer-crawler-postgres createdb -U postgres flyer_crawler_dev
+   ```
+
+## Security Considerations
+
+### Development Only
+
+The default credentials (`postgres:postgres`) are for **development only**. Never use these in production.
+
+### Connection String in Config
+
+The connection string includes the password in plain text. This is acceptable for:
+
+- Local development
+- Container environments
+
+For production MCP access (if ever needed):
+
+- Use environment variables
+- Consider connection pooling
+- Implement proper access controls
+
+### Query Permissions
+
+The MCP server executes queries as the configured user (`postgres` in dev). Be aware that:
+
+- `postgres` is a superuser with full access
+- For restricted access, create a dedicated MCP user with limited permissions:
+
+```sql
+-- Example: Create read-only MCP user
+CREATE USER mcp_reader WITH PASSWORD 'secure_password';
+GRANT CONNECT ON DATABASE flyer_crawler_dev TO mcp_reader;
+GRANT USAGE ON SCHEMA public TO mcp_reader;
+GRANT SELECT ON ALL TABLES IN SCHEMA public TO mcp_reader;
+```
+
+## Database Information
+
+### Development Environment
+
+| Property              | Value                     |
+| --------------------- | ------------------------- |
+| Container             | `flyer-crawler-postgres`  |
+| Image                 | `postgis/postgis:15-3.4`  |
+| Host (from Windows)   | `127.0.0.1` / `localhost` |
+| Host (from container) | `postgres`                |
+| Port                  | `5432`                    |
+| Database              | `flyer_crawler_dev`       |
+| User                  | `postgres`                |
+| Password              | `postgres`                |
+
+### Schema Reference
+
+The database uses PostGIS for geographic data. Key tables include:
+
+- `users` - User accounts
+- `stores` - Store definitions
+- `store_locations` - Store geographic locations
+- `flyers` - Uploaded flyer metadata
+- `flyer_items` - Extracted deal items

+# Database Schema Relationship Analysis
+
+## Executive Summary
+
+This document analyzes the database schema to identify missing table relationships and JOINs that aren't properly implemented in the codebase. This analysis was triggered by discovering that `WatchedItemDeal` was using a `store_name` string instead of a proper `store` object with nested locations.
+
+## Key Findings
+
+### ✅ CORRECTLY IMPLEMENTED
+
+#### 1. Store → Store Locations → Addresses (3-table normalization)
+
+**Schema:**
+
+```sql
+stores (store_id) → store_locations (store_location_id) → addresses (address_id)
+```
+
+**Implementation:**
+
+- [src/services/db/storeLocation.db.ts](src/services/db/storeLocation.db.ts) properly JOINs all three tables
+- [src/types.ts](src/types.ts) defines `StoreWithLocations` interface with nested address objects
+- Recent fixes corrected `WatchedItemDeal` to use `store` object instead of `store_name` string
+
+**Queries:**
+
+```typescript
+// From storeLocation.db.ts
+FROM public.stores s
+LEFT JOIN public.store_locations sl ON s.store_id = sl.store_id
+LEFT JOIN public.addresses a ON sl.address_id = a.address_id
+```
+
+#### 2. Shopping Trips → Shopping Trip Items
+
+**Schema:**
+
+```sql
+shopping_trips (shopping_trip_id) → shopping_trip_items (shopping_trip_item_id) → master_grocery_items
+```
+
+**Implementation:**
+
+- [src/services/db/shopping.db.ts:513-518](src/services/db/shopping.db.ts#L513-L518) properly JOINs shopping_trips → shopping_trip_items → master_grocery_items
+- Uses `json_agg` to nest items array within trip object
+- [src/types.ts:639-647](src/types.ts#L639-L647) `ShoppingTrip` interface includes nested `items: ShoppingTripItem[]`
+
+**Queries:**
+
+```typescript
+FROM public.shopping_trips st
+LEFT JOIN public.shopping_trip_items sti ON st.shopping_trip_id = sti.shopping_trip_id
+LEFT JOIN public.master_grocery_items mgi ON sti.master_item_id = mgi.master_grocery_item_id
+```
+
+#### 3. Receipts → Receipt Items
+
+**Schema:**
+
+```sql
+receipts (receipt_id) → receipt_items (receipt_item_id)
+```
+
+**Implementation:**
+
+- [src/types.ts:649-662](src/types.ts#L649-L662) `Receipt` interface includes optional `items?: ReceiptItem[]`
+- Receipt items are fetched separately via repository methods
+- Proper foreign key relationship maintained
+
+---
+
+### ❌ MISSING / INCORRECT IMPLEMENTATIONS
+
+#### 1. **CRITICAL: Flyers → Flyer Locations → Store Locations (Many-to-Many)**
+
+**Schema:**
+
+```sql
+CREATE TABLE IF NOT EXISTS public.flyer_locations (
+    flyer_id BIGINT NOT NULL REFERENCES public.flyers(flyer_id) ON DELETE CASCADE,
+    store_location_id BIGINT NOT NULL REFERENCES public.store_locations(store_location_id) ON DELETE CASCADE,
+    PRIMARY KEY (flyer_id, store_location_id),
+    ...
+);
+COMMENT: 'A linking table associating a single flyer with multiple store locations where its deals are valid.'
+```
+
+**Problem:**
+
+- The schema defines a **many-to-many relationship** - a flyer can be valid at multiple store locations
+- Current implementation in [src/services/db/flyer.db.ts](src/services/db/flyer.db.ts) **IGNORES** the `flyer_locations` table entirely
+- Queries JOIN `flyers` directly to `stores` via `store_id` foreign key
+- This means flyers can only be associated with ONE store, not multiple locations
+
+**Current (Incorrect) Queries:**
+
+```typescript
+// From flyer.db.ts:315-362
+FROM public.flyers f
+JOIN public.stores s ON f.store_id = s.store_id  // ❌ Wrong - ignores flyer_locations
+```
+
+**Expected (Correct) Queries:**
+
+```typescript
+// Should be:
+FROM public.flyers f
+JOIN public.flyer_locations fl ON f.flyer_id = fl.flyer_id
+JOIN public.store_locations sl ON fl.store_location_id = sl.store_location_id
+JOIN public.stores s ON sl.store_id = s.store_id
+JOIN public.addresses a ON sl.address_id = a.address_id
+```
+
+**TypeScript Type Issues:**
+
+- [src/types.ts](src/types.ts) `Flyer` interface has `store` object, but it should have `locations: StoreLocation[]` array
+- Current structure assumes one store per flyer, not multiple locations
+
+**Files Affected:**
+
+- [src/services/db/flyer.db.ts](src/services/db/flyer.db.ts) - All flyer queries
+- [src/types.ts](src/types.ts) - `Flyer` interface definition
+- Any component displaying flyer locations
+
+---
+
+#### 2. **User Submitted Prices → Store Locations (MIGRATED)**
+
+**Status**: ✅ **FIXED** - Migration created
+
+**Schema:**
+
+```sql
+CREATE TABLE IF NOT EXISTS public.user_submitted_prices (
+    ...
+    store_id BIGINT NOT NULL REFERENCES public.stores(store_id) ON DELETE CASCADE,
+    ...
+);
+```
+
+**Solution Implemented:**
+
+- Created migration [sql/migrations/005_add_store_location_to_user_submitted_prices.sql](sql/migrations/005_add_store_location_to_user_submitted_prices.sql)
+- Added `store_location_id` column to table (NOT NULL after migration)
+- Migrated existing data: linked each price to first location of its store
+- Updated TypeScript interface [src/types.ts:270-282](src/types.ts#L270-L282) to include both fields
+- Kept `store_id` for backward compatibility during transition
+
+**Benefits:**
+
+- Prices are now specific to individual store locations
+- "Walmart Toronto" and "Walmart Vancouver" prices are tracked separately
+- Improves geographic specificity for price comparisons
+- Enables proximity-based price recommendations
+
+**Next Steps:**
+
+- Application code needs to be updated to use `store_location_id` when creating new prices
+- Once all code is migrated, can drop the legacy `store_id` column
+- User-submitted prices feature is not yet implemented in the UI
+
+---
+
+#### 3. **Receipts → Store Locations (MIGRATED)**
+
+**Status**: ✅ **FIXED** - Migration created
+
+**Schema:**
+
+```sql
+CREATE TABLE IF NOT EXISTS public.receipts (
+    ...
+    store_id BIGINT REFERENCES public.stores(store_id) ON DELETE CASCADE,
+    store_location_id BIGINT REFERENCES public.store_locations(store_location_id) ON DELETE SET NULL,
+    ...
+);
+```
+
+**Solution Implemented:**
+
+- Created migration [sql/migrations/006_add_store_location_to_receipts.sql](sql/migrations/006_add_store_location_to_receipts.sql)
+- Added `store_location_id` column to table (nullable - receipts may not have matched store)
+- Migrated existing data: linked each receipt to first location of its store
+- Updated TypeScript interface [src/types.ts:661-675](src/types.ts#L661-L675) to include both fields
+- Kept `store_id` for backward compatibility during transition
+
+**Benefits:**
+
+- Receipts can now be tied to specific store locations
+- "Loblaws Queen St" and "Loblaws Bloor St" are tracked separately
+- Enables location-specific shopping pattern analysis
+- Improves receipt matching accuracy with address data
+
+**Next Steps:**
+
+- Receipt scanning code needs to determine specific store_location_id from OCR text
+- May require address parsing/matching logic in receipt processing
+- Once all code is migrated, can drop the legacy `store_id` column
+- OCR confidence and pattern matching should prefer location-specific data
+
+---
+
+#### 4. Item Price History → Store Locations (Already Correct!)
+
+**Schema:**
+
+```sql
+CREATE TABLE IF NOT EXISTS public.item_price_history (
+    ...
+    store_location_id BIGINT REFERENCES public.store_locations(store_location_id) ON DELETE CASCADE,
+    ...
+);
+```
+
+**Status:**
+
+- ✅ **CORRECTLY IMPLEMENTED** - This table already uses `store_location_id`
+- Properly tracks price history per location
+- Good example of how other tables should be structured
+
+---

+
+## Impact Assessment
+
+### Critical (Must Fix)
+
+1. **Flyer Locations Many-to-Many**
+   - **Impact:** Flyers can't be associated with multiple store locations
+   - **User Impact:** Users can't see which specific store locations have deals
+   - **Business Logic:** Breaks core assumption that one flyer can be valid at multiple stores
+   - **Fix Complexity:** High - requires schema migration, type changes, query rewrites
+
+### Medium (Should Consider)
+
+2. **User Submitted Prices & Receipts**
+   - **Impact:** Loss of location-specific data
+   - **User Impact:** Can't distinguish between different locations of same store chain
+   - **Business Logic:** Reduces accuracy of proximity-based recommendations
+   - **Fix Complexity:** Medium - requires migration and query updates
+
+---
+
+## Recommended Actions
+
+### Phase 1: Fix Flyer Locations (Critical)
+
+1. Create migration to properly use `flyer_locations` table
+2. Update `Flyer` TypeScript interface to support multiple locations
+3. Rewrite all flyer queries in [src/services/db/flyer.db.ts](src/services/db/flyer.db.ts)
+4. Update flyer creation/update endpoints to manage `flyer_locations` entries
+5. Update frontend components to display multiple locations per flyer
+6. Update tests to use new structure
+
+### Phase 2: Consider Store Location Specificity (Optional)
+
+1. Evaluate if location-specific receipts and prices provide value
+2. If yes, create migrations to change `store_id` → `store_location_id`
+3. Update repository queries
+4. Update TypeScript interfaces
+5. Update tests

+## Analysis Methodology
+
+This analysis was conducted by:
+
+1. Extracting all foreign key relationships from [sql/master_schema_rollup.sql](sql/master_schema_rollup.sql)
+2. Comparing schema relationships against TypeScript interfaces in [src/types.ts](src/types.ts)
+3. Auditing database queries in [src/services/db/](src/services/db/) for proper JOIN usage
+4. Identifying gaps where schema relationships exist but aren't used in queries
+
+Commands used:
+
+```bash
+# Extract all foreign keys
+podman exec -it flyer-crawler-dev bash -c "grep -n 'REFERENCES' sql/master_schema_rollup.sql"
+
+# Check specific table structures
+podman exec -it flyer-crawler-dev bash -c "grep -A 15 'CREATE TABLE.*table_name' sql/master_schema_rollup.sql"
+
+# Verify query patterns
+podman exec -it flyer-crawler-dev bash -c "grep -n 'JOIN.*table_name' src/services/db/*.ts"
+```

+## Architecture Patterns (ADR Summary)
+
+### Layer Flow
+
+```
+Route → validateRequest(schema) → Service → Repository → Database
+                                    ↓
+                              External APIs
+```
+
+### Repository Naming Convention (ADR-034)
+
+| Prefix    | Behavior                          | Return         |
+| --------- | --------------------------------- | -------------- |
+| `get*`    | Throws `NotFoundError` if missing | Entity         |
+| `find*`   | Returns `null` if missing         | Entity \| null |
+| `list*`   | Returns empty array if none       | Entity[]       |
+| `create*` | Creates new record                | Entity         |
+| `update*` | Updates existing                  | Entity         |
+| `delete*` | Removes record                    | void           |
+
+### Error Handling (ADR-001)
+
+```typescript
+import { handleDbError, NotFoundError } from '../services/db/errors.db';
+import { logger } from '../services/logger.server';
+
+// Repository pattern
+async function getById(id: string): Promise<Entity> {
+  try {
+    const result = await pool.query('SELECT * FROM table WHERE id = $1', [id]);
+    if (result.rows.length === 0) throw new NotFoundError('Entity not found');
+    return result.rows[0];
+  } catch (error) {
+    handleDbError(error, logger, 'Failed to get entity', { id });
+  }
+}
+```
+
+### API Response Helpers (ADR-028)
+
+```typescript
+import {
+  sendSuccess,
+  sendPaginated,
+  sendError,
+  sendNoContent,
+  sendMessage,
+  ErrorCode,
+} from '../utils/apiResponse';
+
+// Success with data
+sendSuccess(res, data); // 200
+sendSuccess(res, data, 201); // 201 Created
+
+// Paginated
+sendPaginated(res, items, { page, limit, total });
+
+// Error
+sendError(res, ErrorCode.NOT_FOUND, 'User not found', 404);
+sendError(res, ErrorCode.VALIDATION_ERROR, 'Invalid input', 400, validationErrors);
+
+// No content / Message
+sendNoContent(res); // 204
+sendMessage(res, 'Password updated');
+```
+
+### Transaction Pattern (ADR-002)
+
+```typescript
+import { withTransaction } from '../services/db/connection.db';
+
+const result = await withTransaction(async (client) => {
+  await client.query('INSERT INTO a ...');
+  await client.query('INSERT INTO b ...');
+  return { success: true };
+});
+```
+
+---
+
+## Adding New Features
+
+### New API Endpoint Checklist
+
+1. **Schema** (`src/schemas/{domain}.schemas.ts`)
+
+   ```typescript
+   import { z } from 'zod';
+   export const createEntitySchema = z.object({
+     body: z.object({ name: z.string().min(1) }),
+   });
+   ```
+
+2. **Route** (`src/routes/{domain}.routes.ts`)
+
+   ```typescript
+   import { validateRequest } from '../middleware/validation.middleware';
+   import { createEntitySchema } from '../schemas/{domain}.schemas';
+
+   router.post('/', validateRequest(createEntitySchema), async (req, res, next) => {
+     try {
+       const result = await entityService.create(req.body);
+       sendSuccess(res, result, 201);
+     } catch (error) {
+       next(error);
+     }
+   });
+   ```
+
+3. **Service** (`src/services/{domain}Service.server.ts`)
+
+   ```typescript
+   export async function create(data: CreateInput): Promise<Entity> {
+     // Business logic here
+     return repository.create(data);
+   }
+   ```
+
+4. **Repository** (`src/services/db/{domain}.db.ts`)
+   ```typescript
+   export async function create(data: CreateInput, client?: PoolClient): Promise<Entity> {
+     const pool = client || getPool();
+     try {
+       const result = await pool.query('INSERT INTO ...', [data.name]);
+       return result.rows[0];
+     } catch (error) {
+       handleDbError(error, logger, 'Failed to create entity', { data });
+     }
+   }
+   ```
+
+### New Background Job Checklist
+
+1. **Queue** (`src/services/queues.server.ts`)
+
+   ```typescript
+   export const myQueue = new Queue('my-queue', { connection: redisConnection });
+   ```
+
+2. **Worker** (`src/services/workers.server.ts`)
+
+   ```typescript
+   new Worker(
+     'my-queue',
+     async (job) => {
+       // Process job
+     },
+     { connection: redisConnection },
+   );
+   ```
+
+3. **Trigger** (in service)
+   ```typescript
+   await myQueue.add('job-name', { data });
+   ```

+
+| Table                 | Purpose              | Key Columns                                                     |
+| --------------------- | -------------------- | --------------------------------------------------------------- |
+| `users`               | Authentication       | `user_id` (UUID PK), `email`, `password_hash`                   |
+| `profiles`            | User data            | `user_id` (FK), `full_name`, `role`, `points`                   |
+| `addresses`           | Normalized addresses | `address_id`, `address_line_1`, `city`, `latitude`, `longitude` |
+| `stores`              | Store chains         | `store_id`, `name`, `logo_url`                                  |
+| `store_locations`     | Physical locations   | `store_location_id`, `store_id` (FK), `address_id` (FK)         |
+| `flyers`              | Uploaded flyers      | `flyer_id`, `store_id` (FK), `image_url`, `status`              |

+
+## Schema Sync Rule (CRITICAL)
+
+**Both files MUST stay synchronized:**
+
+- `sql/master_schema_rollup.sql` - Used by test DB setup
+- `sql/initial_schema.sql` - Used for fresh installs
+
+**When adding columns:**
+
+1. Add migration in `sql/migrations/NNN_description.sql`
+2. Add column to `master_schema_rollup.sql`
+3. Add column to `initial_schema.sql`
+4. Test DB uses `master_schema_rollup.sql` - out-of-sync = test failures
+
+---
+
+## Migration Pattern
+
+### Creating a Migration
+
+```sql
+-- sql/migrations/NNN_descriptive_name.sql
+
+-- Add column with default
+ALTER TABLE public.flyers
+ADD COLUMN IF NOT EXISTS new_column TEXT DEFAULT 'value';
+
+-- Add index
+CREATE INDEX IF NOT EXISTS idx_flyers_new_column
+ON public.flyers(new_column);
+
+-- Update schema_info
+UPDATE public.schema_info
+SET schema_hash = 'new_hash', updated_at = now()
+WHERE environment = 'production';
+```
+
+### Running Migrations
+
+```bash
+# Via psql
+PGPASSWORD=$DB_PASSWORD psql -h $DB_HOST -U $DB_USER -d $DB_NAME -f sql/migrations/NNN_description.sql
+
+# In CI/CD - migrations are checked via schema hash
+```
+
+---
+
+## Repository Pattern (ADR-034)
+
+### Method Naming Convention
+
+| Prefix    | Behavior                          | Return Type      |
+| --------- | --------------------------------- | ---------------- |
+| `get*`    | Throws `NotFoundError` if missing | `Entity`         |
+| `find*`   | Returns `null` if missing         | `Entity \| null` |
+| `list*`   | Returns empty array if none       | `Entity[]`       |
+| `create*` | Creates new record                | `Entity`         |
+| `update*` | Updates existing record           | `Entity`         |
+| `delete*` | Removes record                    | `void`           |
+| `count*`  | Returns count                     | `number`         |
+
+### Repository Template
+
+```typescript
+// src/services/db/entity.db.ts
+import { getPool } from './connection.db';
+import { handleDbError, NotFoundError } from './errors.db';
+import type { PoolClient } from 'pg';
+import type { Logger } from 'pino';
+
+export async function getEntityById(
+  id: string,
+  logger: Logger,
+  client?: PoolClient,
+): Promise<Entity> {
+  const pool = client || getPool();
+  try {
+    const result = await pool.query('SELECT * FROM public.entities WHERE entity_id = $1', [id]);
+    if (result.rows.length === 0) {
+      throw new NotFoundError('Entity not found');
+    }
+    return result.rows[0];
+  } catch (error) {
+    handleDbError(error, logger, 'Failed to get entity', { id });
+  }
+}
+
+export async function findEntityByName(
+  name: string,
+  logger: Logger,
+  client?: PoolClient,
+): Promise<Entity | null> {
+  const pool = client || getPool();
+  try {
+    const result = await pool.query('SELECT * FROM public.entities WHERE name = $1', [name]);
+    return result.rows[0] || null;
+  } catch (error) {
+    handleDbError(error, logger, 'Failed to find entity', { name });
+  }
+}
+
+export async function listEntities(logger: Logger, client?: PoolClient): Promise<Entity[]> {
+  const pool = client || getPool();
+  try {
+    const result = await pool.query('SELECT * FROM public.entities ORDER BY name');
+    return result.rows;
+  } catch (error) {
+    handleDbError(error, logger, 'Failed to list entities', {});
+  }
+}
+```
+
+---
+
+## Transaction Pattern (ADR-002)
+
+```typescript
+import { withTransaction } from './connection.db';
+
+const result = await withTransaction(async (client) => {
+  // All queries use same client
+  const user = await userRepo.createUser(data, logger, client);
+  const profile = await profileRepo.createProfile(user.user_id, profileData, logger, client);
+  await activityRepo.logActivity('user_created', user.user_id, logger, client);
+  return { user, profile };
+});
+// Commits on success, rolls back on any error
+```
+
+---
+
+## Error Handling (ADR-001)
+
+### Error Types
+
+| Error                            | PostgreSQL Code | HTTP Status | Use Case                  |
+| -------------------------------- | --------------- | ----------- | ------------------------- |
+| `UniqueConstraintError`          | `23505`         | 409         | Duplicate record          |
+| `ForeignKeyConstraintError`      | `23503`         | 400         | Referenced record missing |
+| `NotNullConstraintError`         | `23502`         | 400         | Required field null       |
+| `CheckConstraintError`           | `23514`         | 400         | Check constraint violated |
+| `InvalidTextRepresentationError` | `22P02`         | 400         | Invalid type format       |
+| `NumericValueOutOfRangeError`    | `22003`         | 400         | Number out of range       |
+| `NotFoundError`                  | -               | 404         | Record not found          |
+| `ForbiddenError`                 | -               | 403         | Access denied             |
+
+### Using handleDbError
+
+```typescript
+import { handleDbError, NotFoundError } from './errors.db';
+
+try {
+  const result = await pool.query('INSERT INTO ...', [data]);
+  if (result.rows.length === 0) throw new NotFoundError('Entity not found');
+  return result.rows[0];
+} catch (error) {
+  handleDbError(
+    error,
+    logger,
+    'Failed to create entity',
+    { data },
+    {
+      uniqueMessage: 'Entity with this name already exists',
+      fkMessage: 'Referenced category does not exist',
+      defaultMessage: 'Failed to create entity',
+    },
+  );
+}
+```
+
+---
+
+## Connection Pool
+
+```typescript
+import { getPool, getPoolStatus } from './connection.db';
+
+// Get pool (singleton)
+const pool = getPool();
+
+// Check pool status
+const status = getPoolStatus();
+// { totalCount: 20, idleCount: 15, waitingCount: 0 }
+```
+
+### Pool Configuration
+
+| Setting                   | Value | Purpose             |
+| ------------------------- | ----- | ------------------- |
+| `max`                     | 20    | Max clients in pool |
+| `idleTimeoutMillis`       | 30000 | Idle client timeout |
+| `connectionTimeoutMillis` | 2000  | Connection timeout  |
+
+---
+
+## Common Queries
+
+### Paginated List
+
+```typescript
+const result = await pool.query(
+  `SELECT * FROM public.flyers
+   ORDER BY created_at DESC
+   LIMIT $1 OFFSET $2`,
+  [limit, (page - 1) * limit],
+);
+
+const countResult = await pool.query('SELECT COUNT(*) FROM public.flyers');
+const total = parseInt(countResult.rows[0].count, 10);
+```
+
+### Spatial Query (Find Nearby)
+
+```typescript
+const result = await pool.query(
+  `SELECT sl.*, a.*,
+   ST_Distance(a.location, ST_SetSRID(ST_MakePoint($1, $2), 4326)::geography) as distance
+   FROM public.store_locations sl
+   JOIN public.addresses a ON sl.address_id = a.address_id
+   WHERE ST_DWithin(a.location, ST_SetSRID(ST_MakePoint($1, $2), 4326)::geography, $3)
+   ORDER BY distance`,
+  [longitude, latitude, radiusMeters],
+);
+```
+
+### Upsert Pattern
+
+```typescript
+const result = await pool.query(
+  `INSERT INTO public.stores (name, logo_url)
+   VALUES ($1, $2)
+   ON CONFLICT (name) DO UPDATE SET
+     logo_url = EXCLUDED.logo_url,
+     updated_at = now()
+   RETURNING *`,
+  [name, logoUrl],
+);
+```
+
+---
+
+## Database Reset Commands
+
+### Dev Container
+
+```bash
+# Reset dev database (runs seed script)
+podman exec -it flyer-crawler-dev npm run db:reset:dev
+
+# Reset test database
+podman exec -it flyer-crawler-dev npm run db:reset:test

+
+## MCP Server Configuration
+
+### Global Config: `~/.claude/settings.json`
+
+Used for production/remote servers (HTTPS works fine).
+
+```json
+{
+  "mcpServers": {
+    "bugsink": {
+      "command": "node",
+      "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+      "env": {
+        "BUGSINK_URL": "https://bugsink.projectium.com",
+        "BUGSINK_TOKEN": "<40-char-hex-token>"
+      }
+    }
+  }
+}
+```
+
+### Project Config: `.mcp.json`
+
+**CRITICAL:** Use project-level `.mcp.json` for localhost servers. Global config has issues loading localhost stdio MCP servers.
+
+```json
+{
+  "mcpServers": {
+    "localerrors": {
+      "command": "d:\\nodejs\\node.exe",
+      "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+      "env": {
+        "BUGSINK_URL": "http://127.0.0.1:8000",
+        "BUGSINK_TOKEN": "<40-char-hex-token>"
+      }
+    },
+    "devdb": {
+      "command": "D:\\nodejs\\npx.cmd",
+      "args": [
+        "-y",
+        "@modelcontextprotocol/server-postgres",
+        "postgresql://postgres:postgres@127.0.0.1:5432/flyer_crawler_dev"

+
+## Troubleshooting MCP Servers
+
+### Server Not Loading
+
+1. **Check server name** - Avoid shared prefixes (e.g., `bugsink` and `bugsink-dev`)
+2. **Use project-level `.mcp.json`** for localhost servers
+3. **Restart Claude Code** after config changes
+
+### Test Connection Manually
+
+```bash
+# Bugsink
+set BUGSINK_URL=http://localhost:8000
+set BUGSINK_TOKEN=<token>
+node d:\gitea\bugsink-mcp\dist\index.js
+
+# PostgreSQL
+npx -y @modelcontextprotocol/server-postgres "postgresql://postgres:postgres@127.0.0.1:5432/flyer_crawler_dev"
+```
+
+### Check Claude Debug Logs
+
+```
+C:\Users\<username>\.claude\debug\*.txt
+```
+
+Look for "Starting connection" messages - missing server = never started.

+
+## Known Integration Test Issues
+
+### 1. Vitest globalSetup Context Isolation
+
+**Problem**: globalSetup runs in separate Node.js context. Singletons/mocks don't share instances.
+
+**Affected**: BullMQ worker mocks
+
+**Solution**: Use `.todo()`, test-only API endpoints, or Redis-based flags.
+
+### 2. Cleanup Queue Race Condition
+
+**Problem**: Cleanup worker processes jobs before test verification.
+
+**Solution**:
+
+```typescript
+const { cleanupQueue } = await import('../../services/queues.server');
+await cleanupQueue.drain();
+await cleanupQueue.pause();
+// ... run test ...
+await cleanupQueue.resume();
+```
+
+### 3. Cache Stale After Direct SQL
+
+**Problem**: Direct `pool.query()` bypasses cache invalidation.
+
+**Solution**:
+
+```typescript
+await pool.query('INSERT INTO flyers ...');
+await cacheService.invalidateFlyers(); // Add this
+```
+
+### 4. File Upload Filename Collisions
+
+**Problem**: Multer predictable filenames cause race conditions.
+
+**Solution**:
+
+```typescript
+const filename = `test-${Date.now()}-${Math.round(Math.random() * 1e9)}.jpg`;
+```
+
+### 5. Response Format Mismatches
+
+**Problem**: API response structure changes (`data.jobId` vs `data.job.id`).
+
+**Solution**: Log response bodies, update assertions to match actual format.
+
+---
+
+## Test Patterns
+
+### Unit Test Pattern
+
+```typescript
+import { describe, it, expect, vi, beforeEach } from 'vitest';
+
+describe('MyService', () => {
+  beforeEach(() => {
+    vi.clearAllMocks();
+  });
+
+  it('should do something', () => {
+    // Arrange
+    const input = { data: 'test' };
+
+    // Act
+    const result = myService.process(input);
+
+    // Assert
+    expect(result).toBe('expected');
+  });
+});
+```
+
+### Integration Test Pattern
+
+```typescript
+import { describe, it, expect, beforeEach, afterEach } from 'vitest';
+import request from 'supertest';
+import { createAndLoginUser } from '../utils/testHelpers';
+import { cleanupDb } from '../utils/cleanup';
+
+describe('API Integration', () => {
+  let user, token;
+
+  beforeEach(async () => {
+    const result = await createAndLoginUser({ request: request(app) });
+    user = result.user;
+    token = result.token;
+  });
+
+  afterEach(async () => {
+    await cleanupDb({ userIds: [user.user.user_id] });
+  });
+
+  it('GET /api/resource returns data', async () => {
+    const res = await request(app).get('/api/resource').set('Authorization', `Bearer ${token}`);
+
+    expect(res.status).toBe(200);
+    expect(res.body.success).toBe(true);
+  });
+});
+```
+
+### Route Test Pattern
+
+```typescript
+import { describe, it, expect, vi, beforeEach } from 'vitest';
+import request from 'supertest';
+import { createTestApp } from '../tests/utils/createTestApp';
+
+vi.mock('../services/db/flyer.db', () => ({
+  getFlyerById: vi.fn(),
+}));
+
+describe('Flyer Routes', () => {
+  let app;
+
+  beforeEach(() => {
+    vi.clearAllMocks();
+    app = createTestApp();
+  });
+
+  it('GET /api/flyers/:id returns flyer', async () => {
+    const mockFlyer = { id: '123', name: 'Test' };
+    vi.mocked(flyerRepo.getFlyerById).mockResolvedValue(mockFlyer);
+
+    const res = await request(app).get('/api/flyers/123');
+
+    expect(res.status).toBe(200);
+    expect(res.body.data).toEqual(mockFlyer);
+  });
+});
+```
+
+---
+
+## Mocking Patterns
+
+### Mock Modules
+
+```typescript
+// At top of test file
+vi.mock('../services/db/flyer.db', () => ({
+  getFlyerById: vi.fn(),
+  listFlyers: vi.fn(),
+}));
+
+// In test
+import * as flyerDb from '../services/db/flyer.db';
+vi.mocked(flyerDb.getFlyerById).mockResolvedValue(mockFlyer);
+```
+
+### Mock React Query
+
+```typescript
+vi.mock('@tanstack/react-query', async () => {
+  const actual = await vi.importActual('@tanstack/react-query');
+  return {
+    ...actual,
+    useQuery: vi.fn().mockReturnValue({
+      data: mockData,
+      isLoading: false,
+      error: null,
+    }),
+  };
+});
+```
+
+### Mock Pino Logger
+
+```typescript
+import { createMockLogger } from '../tests/utils/mockLogger';
+const mockLogger = createMockLogger();
+```
+
+---
+
+## Testing React Components
+
+```typescript
+import { render, screen, fireEvent, waitFor } from '@testing-library/react';
+import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
+import { BrowserRouter } from 'react-router-dom';
+
+const createWrapper = () => {
+  const queryClient = new QueryClient({
+    defaultOptions: { queries: { retry: false } },
+  });
+  return ({ children }) => (
+    <QueryClientProvider client={queryClient}>
+      <BrowserRouter>{children}</BrowserRouter>
+    </QueryClientProvider>
+  );
+};
+
+it('renders component', () => {
+  render(<MyComponent />, { wrapper: createWrapper() });
+  expect(screen.getByText('Expected Text')).toBeInTheDocument();
+});
+```
+
+---
+
+## Test Coverage
+
+```bash
+# Generate coverage report
+podman exec -it flyer-crawler-dev npm run test:coverage
+
+# View HTML report
+# Coverage reports generated in coverage/ directory
+```
+
+---
+
+## Debugging Tests
+
+```bash
+# Verbose output
+npm test -- --reporter=verbose
+
+# Run single test with debugging
+DEBUG=* npm test -- --run src/path/to/test.test.ts
+

+- [src/pages/MyDealsPage.tsx](../../src/pages/MyDealsPage.tsx) - Now uses useBestSalePricesQuery
+- [src/hooks/useActiveDeals.tsx](../../src/hooks/useActiveDeals.tsx) - Refactored to use TanStack Query hooks
 
-**Note**: `useApi` and `useApiOnMount` are still actively used in 6 production files for authentication, profile management, and some admin features. Full migration of these critical features requires careful planning and is documented as future work.
+**Benefits Achieved:**
+
+- ✅ Removed useApi dependency from analytics features
+- ✅ Automatic caching of deal data (2-5 minute stale times)
+- ✅ Consistent error handling via TanStack Query
+- ✅ Batch fetching for flyer items (single query for multiple flyers)
+
+### Phase 7: Cleanup (✅ Complete - 2026-01-10)
+
+**Goal:** Remove legacy hooks once migration is complete.
+
+**Files Created:**
+
+- [src/hooks/queries/useUserAddressQuery.ts](../../src/hooks/queries/useUserAddressQuery.ts) - User address fetching
+- [src/hooks/queries/useAuthProfileQuery.ts](../../src/hooks/queries/useAuthProfileQuery.ts) - Auth profile fetching
+- [src/hooks/mutations/useGeocodeMutation.ts](../../src/hooks/mutations/useGeocodeMutation.ts) - Address geocoding
+
+**Files Modified:**
+
+- [src/hooks/useProfileAddress.ts](../../src/hooks/useProfileAddress.ts) - Refactored to use TanStack Query
+- [src/providers/AuthProvider.tsx](../../src/providers/AuthProvider.tsx) - Refactored to use TanStack Query
+
+**Files Removed:**
+
+- ~~src/hooks/useApi.ts~~ - Legacy hook removed
+- ~~src/hooks/useApi.test.ts~~ - Test file removed
+- ~~src/hooks/useApiOnMount.ts~~ - Legacy hook removed
+- ~~src/hooks/useApiOnMount.test.ts~~ - Test file removed
+
+**Benefits Achieved:**
+
+- ✅ Removed all legacy `useApi` and `useApiOnMount` hooks
+- ✅ Complete TanStack Query coverage for all data fetching
+- ✅ Consistent error handling across the entire application
+- ✅ Unified caching strategy for all server state
+
+### Phase 8: Additional Component Migration (✅ Complete - 2026-01-10)
+
+**Goal:** Migrate remaining components with manual data fetching to TanStack Query.
+
+**Files Created:**
+
+- [src/hooks/queries/useUserProfileDataQuery.ts](../../src/hooks/queries/useUserProfileDataQuery.ts) - Combined user profile + achievements query
+- [src/hooks/queries/useLeaderboardQuery.ts](../../src/hooks/queries/useLeaderboardQuery.ts) - Public leaderboard data
+- [src/hooks/queries/usePriceHistoryQuery.ts](../../src/hooks/queries/usePriceHistoryQuery.ts) - Historical price data for watched items
+
+**Files Modified:**
+
+- [src/hooks/useUserProfileData.ts](../../src/hooks/useUserProfileData.ts) - Refactored to use useUserProfileDataQuery
+- [src/components/Leaderboard.tsx](../../src/components/Leaderboard.tsx) - Refactored to use useLeaderboardQuery
+- [src/features/charts/PriceHistoryChart.tsx](../../src/features/charts/PriceHistoryChart.tsx) - Refactored to use usePriceHistoryQuery
+
+**Benefits Achieved:**
+
+- ✅ Parallel fetching for profile + achievements data
+- ✅ Public leaderboard cached with 2-minute stale time
+- ✅ Price history cached with 10-minute stale time (data changes infrequently)
+- ✅ Backward-compatible setProfile function via queryClient.setQueryData
+- ✅ Stable query keys with sorted IDs for price history

 3. **E2E tests**: Minimal mocking, use real services where possible
 
+### Testing Code Smells
+
+**When testing requires any of the following patterns, treat it as a code smell indicating the production code needs refactoring:**
+
+1. **Capturing callbacks through mocks**: If you need to capture a callback passed to a mock and manually invoke it to test behavior, the code under test likely has poor separation of concerns.
+
+2. **Complex module resets**: If tests require `vi.resetModules()`, `vi.doMock()`, or careful ordering of mock setup to work correctly, the module likely has problematic initialization or hidden global state.
+
+3. **Indirect verification**: If you can only verify behavior by checking that internal mocks were called with specific arguments (rather than asserting on direct outputs), the code likely lacks proper return values or has side effects that should be explicit.
+
+4. **Excessive mock setup**: If setting up mocks requires more lines than the actual test assertions, consider whether the code under test has too many dependencies or responsibilities.
+
+**The Fix**: Rather than writing complex test scaffolding, refactor the production code to be more testable:
+
+- Extract pure functions that can be tested with simple input/output assertions
+- Use dependency injection to make dependencies explicit and easily replaceable
+- Return values from functions instead of relying on side effects
+- Split modules with complex initialization into smaller, focused units
+- Make async flows explicit and controllable rather than callback-based
+
+**Example anti-pattern**:
+
+```typescript
+// BAD: Capturing callback to test behavior
+const capturedCallback = vi.fn();
+mockService.onEvent.mockImplementation((cb) => {
+  capturedCallback = cb;
+});
+await initializeModule();
+capturedCallback('test-data'); // Manually triggering to test
+expect(mockOtherService.process).toHaveBeenCalledWith('test-data');
+```
+
+**Example preferred pattern**:
+
+```typescript
+// GOOD: Direct input/output testing
+const result = await processEvent('test-data');
+expect(result).toEqual({ processed: true, data: 'test-data' });
+```

+## Platform Requirement: Linux Only
+
+**CRITICAL**: This application is designed and intended to run **exclusively on Linux**, either:
+
+- **In a container** (Docker/Podman) - the recommended and primary development environment
+- **On bare-metal Linux** - for production deployments
+
+### Windows Compatibility
+
+**Windows is NOT a supported platform.** Any apparent Windows compatibility is:
+
+- Coincidental and not guaranteed
+- Subject to break at any time without notice
+- Not a priority to fix or maintain
+
+Specific issues that arise on Windows include:
+
+- **Path separators**: The codebase uses POSIX-style paths (`/`) which work natively on Linux but may cause issues with `path.join()` on Windows producing backslash paths
+- **Shell scripts**: Bash scripts in `scripts/` directory are Linux-only
+- **External dependencies**: Tools like `pdftocairo` assume Linux installation paths
+- **File permissions**: Unix-style permissions are assumed throughout
+
+### Test Execution Requirement
+
+**ALL tests MUST be executed on Linux.** This includes:
+
+- Unit tests
+- Integration tests
+- End-to-end tests
+- Any CI/CD pipeline tests
+
+Tests that pass on Windows but fail on Linux are considered **broken tests**. Tests that fail on Windows but pass on Linux are considered **passing tests**.

+## Container Test Readiness Requirement
+
+**CRITICAL**: The development container MUST be fully test-ready on startup. This means:
+
+1. **Zero Manual Steps**: After running `podman-compose -f compose.dev.yml up -d` and entering the container, tests MUST run immediately with `npm test` without any additional setup steps.
+
+2. **Complete Environment**: All environment variables, database connections, Redis connections, and seed data MUST be automatically initialized during container startup.
+
+3. **Enforcement Checklist**:
+   - [ ] `npm test` runs successfully immediately after container start
+   - [ ] Database is seeded with test data (admin account, sample data)
+   - [ ] Redis is connected and healthy
+   - [ ] All environment variables are set via `compose.dev.yml` or `.env` files
+   - [ ] No "database not ready" or "connection refused" errors on first test run
+
+4. **Current Gaps (To Fix)**:
+   - Integration tests require database seeding (`npm run db:reset:test`)
+   - Environment variables from `.env.test` may not be loaded automatically
+   - Some npm scripts use `NODE_ENV=` syntax which fails on Windows (use `cross-env`)
+
+5. **Resolution Steps**:
+   - The `docker-init.sh` script should seed the test database after seeding dev database
+   - Add automatic `.env.test` loading or move all test env vars to `compose.dev.yml`
+   - Update all npm scripts to use `cross-env` for cross-platform compatibility
+
+**Rationale**: Developers and CI systems should never need to run manual setup commands to execute tests. If the container is running, tests should work. Any deviation from this principle indicates an incomplete container setup.

 ## Context
 
-While `ADR-004` established structured logging, the application lacks a high-level, aggregated view of its health, performance, and errors. It's difficult to spot trends, identify slow API endpoints, or be proactively notified of new types of errors.
+While `ADR-004` established structured logging with Pino, the application lacks a high-level, aggregated view of its health, performance, and errors. It's difficult to spot trends, identify slow API endpoints, or be proactively notified of new types of errors.
+
+Key requirements:
+
+1. **Self-hosted**: No external SaaS dependencies for error tracking
+2. **Sentry SDK compatible**: Leverage mature, well-documented SDKs
+3. **Lightweight**: Minimal resource overhead in the dev container
+4. **Production-ready**: Same architecture works on bare-metal production servers
+5. **AI-accessible**: MCP server integration for Claude Code and other AI tools
 
 ## Decision
 
-We will integrate a dedicated Application Performance Monitoring (APM) and error tracking service like **Sentry**, **Datadog**, or **New Relic**. This will define how the service is integrated to automatically capture and report unhandled exceptions, performance data (e.g., transaction traces, database query times), and release health.
+We will implement a self-hosted error tracking stack using **Bugsink** as the Sentry-compatible backend, with the following components:
+
+### 1. Error Tracking Backend: Bugsink
+
+**Bugsink** is a lightweight, self-hosted Sentry alternative that:
+
+- Runs as a single process (no Kafka, Redis, ClickHouse required)
+- Is fully compatible with Sentry SDKs
+- Supports ARM64 and AMD64 architectures
+- Can use SQLite (dev) or PostgreSQL (production)
+
+**Deployment**:
+
+- **Dev container**: Installed as a systemd service inside the container
+- **Production**: Runs as a systemd service on bare-metal, listening on localhost only
+- **Database**: Uses PostgreSQL with a dedicated `bugsink` user and `bugsink` database (same PostgreSQL instance as the main application)
+
+### 2. Backend Integration: @sentry/node
+
+The Express backend will integrate `@sentry/node` SDK to:
+
+- Capture unhandled exceptions before PM2/process manager restarts
+- Report errors with full stack traces and context
+- Integrate with Pino logger for breadcrumbs
+- Track transaction performance (optional)
+
+### 3. Frontend Integration: @sentry/react
+
+The React frontend will integrate `@sentry/react` SDK to:
+
+- Wrap the app in a Sentry Error Boundary
+- Capture unhandled JavaScript errors
+- Report errors with component stack traces
+- Track user session context
+- **Frontend Error Correlation**: The global API client (Axios/Fetch wrapper) MUST intercept 4xx/5xx responses. It MUST extract the `x-request-id` header (if present) and attach it to the Sentry scope as a tag `api_request_id` before re-throwing the error. This allows developers to copy the ID from Sentry and search for it in backend logs.
+
+### 4. Log Aggregation: Logstash
+
+**Logstash** parses application and infrastructure logs, forwarding error patterns to Bugsink:
+
+- **Installation**: Installed inside the dev container (and on bare-metal prod servers)
+- **Inputs**:
+  - Pino JSON logs from the Node.js application
+  - Redis logs (connection errors, memory warnings, slow commands)
+  - PostgreSQL function logs (future - see Implementation Steps)
+- **Filter**: Identifies error-level logs (5xx responses, unhandled exceptions, Redis errors)
+- **Output**: Sends to Bugsink via Sentry-compatible HTTP API
+
+This provides a secondary error capture path for:
+
+- Errors that occur before Sentry SDK initialization
+- Log-based errors that don't throw exceptions
+- Redis connection/performance issues
+- Database function errors and slow queries
+- Historical error analysis from log files
+
+### 5. MCP Server Integration: bugsink-mcp
+
+For AI tool integration (Claude Code, Cursor, etc.), we use the open-source [bugsink-mcp](https://github.com/j-shelfwood/bugsink-mcp) server:
+
+- **No code changes required**: Configurable via environment variables
+- **Capabilities**: List projects, get issues, view events, get stacktraces, manage releases
+- **Configuration**:
+  - `BUGSINK_URL`: Points to Bugsink instance (`http://localhost:8000` for dev, `https://bugsink.projectium.com` for prod)
+  - `BUGSINK_API_TOKEN`: API token from Bugsink (created via Django management command)
+  - `BUGSINK_ORG_SLUG`: Organization identifier (usually "sentry")
+
+**Note:** Despite the name `sentry-selfhosted-mcp` mentioned in earlier drafts of this ADR, the actual MCP server used is `bugsink-mcp` which is specifically designed for Bugsink's API structure.

+
+## Implementation Steps
+
+1. **Update Dockerfile.dev**:
+   - Install Bugsink (pip package or binary)
+   - Install Logstash (Elastic APT repository)
+   - Add systemd service files for both
+
+2. **PostgreSQL initialization**:
+   - Add Bugsink user/database creation to `sql/00-init-extensions.sql`
+
+3. **Backend SDK integration**:
+   - Install `@sentry/node`
+   - Initialize in `server.ts` before Express app
+   - Configure error handler middleware integration
+
+4. **Frontend SDK integration**:
+   - Install `@sentry/react`
+   - Wrap `App` component with `Sentry.ErrorBoundary`
+   - Configure in `src/index.tsx`
+
+5. **Environment configuration**:
+   - Add Bugsink variables to `src/config/env.ts`
+   - Update `.env.example` and `compose.dev.yml`
+
+6. **Logstash configuration**:
+   - Create pipeline config for Pino → Bugsink
+   - Configure Pino to write to log file in addition to stdout
+   - Configure Redis log monitoring (connection errors, slow commands)
+
+7. **MCP server documentation**:
+   - Document `bugsink-mcp` setup in CLAUDE.md
+
+8. **PostgreSQL function logging** (future):
+   - Configure PostgreSQL to log function execution errors
+   - Add Logstash input for PostgreSQL logs
+   - Define filter rules for function-level error detection
+   - _Note: Ask for implementation details when this step is reached_
 
 ## Consequences
 
-**Positive**: Provides critical observability into the application's real-world behavior. Enables proactive identification and resolution of performance bottlenecks and errors. Improves overall application reliability and user experience.
-**Negative**: Introduces a new third-party dependency and potential subscription costs. Requires initial setup and configuration of the APM/error tracking agent.
+### Positive
+
+- **Full observability**: Aggregated view of errors, trends, and performance
+- **Self-hosted**: No external SaaS dependencies or subscription costs
+- **SDK compatibility**: Leverages mature Sentry SDKs with excellent documentation
+- **AI integration**: MCP server enables Claude Code to query and analyze errors
+- **Unified architecture**: Same setup works in dev container and production
+- **Lightweight**: Bugsink runs in a single process, unlike full Sentry (16GB+ RAM)
+
+### Negative
+
+- **Additional services**: Bugsink and Logstash add complexity to the container
+- **PostgreSQL overhead**: Additional database for error tracking
+- **Initial setup**: Requires configuration of multiple components
+- **Logstash learning curve**: Pipeline configuration requires Logstash knowledge
+
+## Alternatives Considered
+
+1. **Full Sentry self-hosted**: Rejected due to complexity (Kafka, Redis, ClickHouse, 16GB+ RAM minimum)
+2. **GlitchTip**: Considered, but Bugsink is lighter weight and easier to deploy
+3. **Sentry SaaS**: Rejected due to self-hosted requirement
+4. **Custom error aggregation**: Rejected in favor of proven Sentry SDK ecosystem

 ## Context
 
 As the API grows, it becomes increasingly difficult for frontend developers and other consumers to understand its endpoints, request formats, and response structures. There is no single source of truth for API documentation.
 
+Key requirements:
+
+1. **Developer Experience**: Developers need interactive documentation to explore and test API endpoints.
+2. **Code-Documentation Sync**: Documentation should stay in sync with the actual code to prevent drift.
+3. **Low Maintenance Overhead**: The documentation approach should be "fast and lite" - minimal additional work for developers.
+4. **Security**: Documentation should not expose sensitive information in production environments.
+
 ## Decision
 
-We will adopt **OpenAPI (Swagger)** for API documentation. We will use tools (e.g., JSDoc annotations with `swagger-jsdoc`) to generate an `openapi.json` specification directly from the route handler source code. This specification will be served via a UI like Swagger UI for interactive exploration.
+We will adopt **OpenAPI 3.0 (Swagger)** for API documentation using the following approach:
+
+1. **JSDoc Annotations**: Use `swagger-jsdoc` to generate OpenAPI specs from JSDoc comments in route files.
+2. **Swagger UI**: Use `swagger-ui-express` to serve interactive documentation at `/docs/api-docs`.
+3. **Environment Restriction**: Only expose the Swagger UI in development and test environments, not production.
+4. **Incremental Adoption**: Start with key public routes and progressively add annotations to all endpoints.
+
+### Tooling Selection
+
+| Tool                 | Purpose                                        |
+| -------------------- | ---------------------------------------------- |
+| `swagger-jsdoc`      | Generates OpenAPI 3.0 spec from JSDoc comments |
+| `swagger-ui-express` | Serves interactive Swagger UI                  |
+
+**Why JSDoc over separate schema files?**
+
+- Documentation lives with the code, reducing drift
+- No separate files to maintain
+- Developers see documentation when editing routes
+- Lower learning curve for the team
+
+## Implementation Details
+
+### OpenAPI Configuration
+
+Located in `src/config/swagger.ts`:
+
+```typescript
+import swaggerJsdoc from 'swagger-jsdoc';
+
+const options: swaggerJsdoc.Options = {
+  definition: {
+    openapi: '3.0.0',
+    info: {
+      title: 'Flyer Crawler API',
+      version: '1.0.0',
+      description: 'API for the Flyer Crawler application',
+      contact: {
+        name: 'API Support',
+      },
+    },
+    servers: [
+      {
+        url: '/api',
+        description: 'API server',
+      },
+    ],
+    components: {
+      securitySchemes: {
+        bearerAuth: {
+          type: 'http',
+          scheme: 'bearer',
+          bearerFormat: 'JWT',
+        },
+      },
+    },
+  },
+  apis: ['./src/routes/*.ts'],
+};
+
+export const swaggerSpec = swaggerJsdoc(options);
+```
+
+### JSDoc Annotation Pattern
+
+Each route handler should include OpenAPI annotations using the `@openapi` tag:
+
+```typescript
+/**
+ * @openapi
+ * /health/ping:
+ *   get:
+ *     summary: Simple ping endpoint
+ *     description: Returns a pong response to verify server is responsive
+ *     tags:
+ *       - Health
+ *     responses:
+ *       200:
+ *         description: Server is responsive
+ *         content:
+ *           application/json:
+ *             schema:
+ *               type: object
+ *               properties:
+ *                 success:
+ *                   type: boolean
+ *                   example: true
+ *                 data:
+ *                   type: object
+ *                   properties:
+ *                     message:
+ *                       type: string
+ *                       example: pong
+ */
+router.get('/ping', validateRequest(emptySchema), (_req: Request, res: Response) => {
+  return sendSuccess(res, { message: 'pong' });
+});
+```
+
+### Route Documentation Priority
+
+Document routes in this order of priority:
+
+1. **Health Routes** - `/api/health/*` (public, critical for operations)
+2. **Auth Routes** - `/api/auth/*` (public, essential for integration)
+3. **Gamification Routes** - `/api/achievements/*` (simple, good example)
+4. **Flyer Routes** - `/api/flyers/*` (core functionality)
+5. **User Routes** - `/api/users/*` (common CRUD patterns)
+6. **Remaining Routes** - Budget, Recipe, Admin, etc.
+
+### Swagger UI Setup
+
+In `server.ts`, add the Swagger UI middleware (development/test only):
+
+```typescript
+import swaggerUi from 'swagger-ui-express';
+import { swaggerSpec } from './src/config/swagger';
+
+// Only serve Swagger UI in non-production environments
+if (process.env.NODE_ENV !== 'production') {
+  app.use('/docs/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerSpec));
+
+  // Optionally expose raw JSON spec for tooling
+  app.get('/docs/api-docs.json', (_req, res) => {
+    res.setHeader('Content-Type', 'application/json');
+    res.send(swaggerSpec);
+  });
+}
+```
+
+### Response Schema Standardization
+
+All API responses follow the standardized format from [ADR-028](./0028-api-response-standardization.md):
+
+```typescript
+// Success response
+{
+  "success": true,
+  "data": { ... }
+}
+
+// Error response
+{
+  "success": false,
+  "error": {
+    "code": "ERROR_CODE",
+    "message": "Human-readable message"
+  }
+}
+```
+
+Define reusable schema components for these patterns:
+
+```typescript
+/**
+ * @openapi
+ * components:
+ *   schemas:
+ *     SuccessResponse:
+ *       type: object
+ *       properties:
+ *         success:
+ *           type: boolean
+ *           example: true
+ *         data:
+ *           type: object
+ *     ErrorResponse:
+ *       type: object
+ *       properties:
+ *         success:
+ *           type: boolean
+ *           example: false
+ *         error:
+ *           type: object
+ *           properties:
+ *             code:
+ *               type: string
+ *             message:
+ *               type: string
+ */
+```
+
+### Security Considerations
+
+1. **Production Disabled**: Swagger UI is not available in production to prevent information disclosure.
+2. **No Sensitive Data**: Never include actual secrets, tokens, or PII in example values.
+3. **Authentication Documented**: Clearly document which endpoints require authentication.
+
+## API Route Tags
+
+Organize endpoints using consistent tags:
+
+| Tag          | Description                        | Routes                |
+| ------------ | ---------------------------------- | --------------------- |
+| Health       | Server health and readiness checks | `/api/health/*`       |
+| Auth         | Authentication and authorization   | `/api/auth/*`         |
+| Users        | User profile management            | `/api/users/*`        |
+| Flyers       | Flyer uploads and retrieval        | `/api/flyers/*`       |
+| Achievements | Gamification and leaderboards      | `/api/achievements/*` |
+| Budgets      | Budget tracking                    | `/api/budgets/*`      |
+| Recipes      | Recipe management                  | `/api/recipes/*`      |
+| Admin        | Administrative operations          | `/api/admin/*`        |
+| System       | System status and monitoring       | `/api/system/*`       |
+
+## Testing
+
+Verify API documentation is correct by:
+
+1. **Manual Review**: Navigate to `/docs/api-docs` and test each endpoint.
+2. **Spec Validation**: Use OpenAPI validators to check the generated spec.
+3. **Integration Tests**: Existing integration tests serve as implicit documentation verification.
 
 ## Consequences
 
-- **Positive**: Creates a single source of truth for API documentation that stays in sync with the code. Enables auto-generation of client SDKs and simplifies testing.
-- **Negative**: Requires developers to maintain JSDoc annotations on all routes. Adds a build step and new dependencies to the project.
+### Positive
+
+- **Single Source of Truth**: Documentation lives with the code and stays in sync.
+- **Interactive Exploration**: Developers can try endpoints directly from the UI.
+- **SDK Generation**: OpenAPI spec enables automatic client SDK generation.
+- **Onboarding**: New developers can quickly understand the API surface.
+- **Low Overhead**: JSDoc annotations are minimal additions to existing code.
+
+### Negative
+
+- **Maintenance Required**: Developers must update annotations when routes change.
+- **Build Dependency**: Adds `swagger-jsdoc` and `swagger-ui-express` packages.
+- **Initial Investment**: Existing routes need annotations added incrementally.

+### Mitigation
+
+- Include documentation checks in code review process.
+- Start with high-priority routes and expand coverage over time.

+
+**Rationale**:
+
+1. **Tests are not production code** - The primary goal of tests is verifying behavior, not type safety of the test code itself
+2. **Mocking complexity** - Mocking libraries often require type gymnastics; `any` simplifies creating partial mocks and test doubles
+3. **Testing edge cases** - Sometimes tests intentionally pass invalid types to verify error handling
+4. **Development velocity** - Strict typing in tests slows down test writing without proportional benefit during active development
+
+**Future Consideration**: This decision should be revisited when the product is nearing its final stages. At that point, stricter linting in tests may be warranted to ensure long-term maintainability.

-**Status**: Proposed
+**Status**: Accepted

 ## Context
 
 A core feature is providing "Active Deal Alerts" to users. The current HTTP-based architecture is not suitable for pushing real-time updates to clients efficiently. Relying on traditional polling would be inefficient and slow.
 
+Users need to be notified immediately when:
+
+1. **New deals are found** on their watched items
+2. **System announcements** need to be broadcast
+3. **Background jobs complete** that affect their data
+
+Traditional approaches:
+
+- **HTTP Polling**: Inefficient, creates unnecessary load, delays up to polling interval
+- **Server-Sent Events (SSE)**: One-way only, no client-to-server messaging
+- **WebSockets**: Bi-directional, real-time, efficient
+
 ## Decision
 
-We will implement a real-time communication system using **WebSockets** (e.g., with the `ws` library or Socket.IO). This will involve an architecture for a notification service that listens for backend events (like a new deal from a background job) and pushes live updates to connected clients.
+We will implement a real-time communication system using **WebSockets** with the `ws` library. This will involve:
+
+1. **WebSocket Server**: Manages connections, authentication, and message routing
+2. **React Hook**: Provides easy integration for React components
+3. **Event Bus Integration**: Bridges WebSocket messages to in-app events
+4. **Background Job Integration**: Emits WebSocket notifications when deals are found
+
+### Design Principles
+
+- **JWT Authentication**: WebSocket connections authenticated via JWT tokens
+- **Type-Safe Messages**: Strongly-typed message formats prevent errors
+- **Auto-Reconnect**: Client automatically reconnects with exponential backoff
+- **Graceful Degradation**: Email + DB notifications remain for offline users
+- **Heartbeat Ping/Pong**: Detect and cleanup dead connections
+- **Singleton Service**: Single WebSocket service instance shared across app
+
+## Implementation Details
+
+### WebSocket Message Types
+
+Located in `src/types/websocket.ts`:
+
+```typescript
+export interface WebSocketMessage<T = unknown> {
+  type: WebSocketMessageType;
+  data: T;
+  timestamp: string;
+}
+
+export type WebSocketMessageType =
+  | 'deal-notification'
+  | 'system-message'
+  | 'ping'
+  | 'pong'
+  | 'error'
+  | 'connection-established';
+
+// Deal notification payload
+export interface DealNotificationData {
+  notification_id?: string;
+  deals: DealInfo[];
+  user_id: string;
+  message: string;
+}
+
+// Type-safe message creators
+export const createWebSocketMessage = {
+  dealNotification: (data: DealNotificationData) => ({ ... }),
+  systemMessage: (data: SystemMessageData) => ({ ... }),
+  error: (data: ErrorMessageData) => ({ ... }),
+  // ...
+};
+```
+
+### WebSocket Server Service
+
+Located in `src/services/websocketService.server.ts`:
+
+```typescript
+export class WebSocketService {
+  private wss: WebSocketServer | null = null;
+  private clients: Map<string, Set<AuthenticatedWebSocket>> = new Map();
+  private pingInterval: NodeJS.Timeout | null = null;
+
+  initialize(server: HTTPServer): void {
+    this.wss = new WebSocketServer({
+      server,
+      path: '/ws',
+    });
+
+    this.wss.on('connection', (ws, request) => {
+      this.handleConnection(ws, request);
+    });
+
+    this.startHeartbeat(); // Ping every 30s
+  }
+
+  // Authentication via JWT from query string or cookie
+  private extractToken(request: IncomingMessage): string | null {
+    // Extract from ?token=xxx or Cookie: accessToken=xxx
+  }
+
+  // Broadcast to specific user
+  broadcastDealNotification(userId: string, data: DealNotificationData): void {
+    const message = createWebSocketMessage.dealNotification(data);
+    this.broadcastToUser(userId, message);
+  }
+
+  // Broadcast to all users
+  broadcastToAll(data: SystemMessageData): void {
+    // Send to all connected clients
+  }
+
+  shutdown(): void {
+    // Gracefully close all connections
+  }
+}
+
+export const websocketService = new WebSocketService(globalLogger);
+```
+
+### Server Integration
+
+Located in `server.ts`:
+
+```typescript
+import { websocketService } from './src/services/websocketService.server';
+
+if (process.env.NODE_ENV !== 'test') {
+  const server = app.listen(PORT, () => {
+    logger.info(`Authentication server started on port ${PORT}`);
+  });
+
+  // Initialize WebSocket server (ADR-022)
+  websocketService.initialize(server);
+  logger.info('WebSocket server initialized for real-time notifications');
+
+  // Graceful shutdown
+  const handleShutdown = (signal: string) => {
+    websocketService.shutdown();
+    gracefulShutdown(signal);
+  };
+
+  process.on('SIGINT', () => handleShutdown('SIGINT'));
+  process.on('SIGTERM', () => handleShutdown('SIGTERM'));
+}
+```
+
+### React Client Hook
+
+Located in `src/hooks/useWebSocket.ts`:
+
+```typescript
+export function useWebSocket(options: UseWebSocketOptions = {}) {
+  const [state, setState] = useState<WebSocketState>({
+    isConnected: false,
+    isConnecting: false,
+    error: null,
+  });
+
+  const connect = useCallback(() => {
+    const url = getWebSocketUrl(); // wss://host/ws?token=xxx
+    const ws = new WebSocket(url);
+
+    ws.onmessage = (event) => {
+      const message = JSON.parse(event.data) as WebSocketMessage;
+
+      // Emit to event bus for cross-component communication
+      switch (message.type) {
+        case 'deal-notification':
+          eventBus.dispatch('notification:deal', message.data);
+          break;
+        case 'system-message':
+          eventBus.dispatch('notification:system', message.data);
+          break;
+        // ...
+      }
+    };
+
+    ws.onclose = () => {
+      // Auto-reconnect with exponential backoff
+      if (reconnectAttempts < maxReconnectAttempts) {
+        setTimeout(connect, reconnectDelay * Math.pow(2, reconnectAttempts));
+        reconnectAttempts++;
+      }
+    };
+  }, []);
+
+  useEffect(() => {
+    if (autoConnect) connect();
+    return () => disconnect();
+  }, [autoConnect, connect, disconnect]);
+
+  return { ...state, connect, disconnect, send };
+}
+```
+
+### Background Job Integration
+
+Located in `src/services/backgroundJobService.ts`:
+
+```typescript
+private async _processDealsForUser({ userProfile, deals }: UserDealGroup) {
+  // ... existing email notification logic ...
+
+  // Send real-time WebSocket notification (ADR-022)
+  const { websocketService } = await import('./websocketService.server');
+  websocketService.broadcastDealNotification(userProfile.user_id, {
+    user_id: userProfile.user_id,
+    deals: deals.map((deal) => ({
+      item_name: deal.item_name,
+      best_price_in_cents: deal.best_price_in_cents,
+      store_name: deal.store.name,
+      store_id: deal.store.store_id,
+    })),
+    message: `You have ${deals.length} new deal(s) on your watched items!`,
+  });
+}
+```
+
+### Usage in React Components
+
+```typescript
+import { useWebSocket } from '../hooks/useWebSocket';
+import { useEventBus } from '../hooks/useEventBus';
+import { useCallback } from 'react';
+
+function NotificationComponent() {
+  // Connect to WebSocket
+  const { isConnected, error } = useWebSocket({ autoConnect: true });
+
+  // Listen for deal notifications via event bus
+  const handleDealNotification = useCallback((data: DealNotificationData) => {
+    toast.success(`${data.deals.length} new deals found!`);
+  }, []);
+
+  useEventBus('notification:deal', handleDealNotification);
+
+  return (
+    <div>
+      {isConnected ? '🟢 Live' : '🔴 Offline'}
+    </div>
+  );
+}
+```

+
+## Security Considerations
+
+1. **Authentication**: JWT tokens required for WebSocket connections
+2. **User Isolation**: Messages routed only to authenticated user's connections
+3. **Rate Limiting**: Heartbeat ping/pong prevents connection flooding
+4. **Graceful Shutdown**: Notifies clients before server shutdown
+5. **Error Handling**: Failed WebSocket sends don't crash the server
 
 ## Consequences
 
-**Positive**: Enables a core, user-facing feature in a scalable and efficient manner. Significantly improves user engagement and experience.
-**Negative**: Introduces a new dependency (e.g., WebSocket library) and adds complexity to the backend and frontend architecture. Requires careful handling of connection management and scaling.
+### Positive
+
+- **Real-time Updates**: Users see deals immediately when found
+- **Better UX**: No page refresh needed, instant notifications
+- **Efficient**: Single persistent connection vs polling every N seconds
+- **Scalable**: Connection pooling per user, heartbeat cleanup
+- **Type-Safe**: TypeScript types prevent message format errors
+- **Resilient**: Auto-reconnect with exponential backoff
+- **Observable**: Connection stats available via `getConnectionStats()`
+- **Testable**: Comprehensive unit tests for message types and service
+
+### Negative
+
+- **Complexity**: WebSocket server adds new infrastructure component
+- **Memory**: Each connection consumes server memory
+- **Scaling**: Single-server implementation (multi-server requires Redis pub/sub)
+- **Browser Support**: Requires WebSocket-capable browsers (all modern browsers)
+- **Network**: Persistent connections require stable network
+
+### Mitigation
+
+- **Graceful Degradation**: Email + DB notifications remain for offline users
+- **Connection Limits**: Can add max connections per user if needed
+- **Monitoring**: Connection stats exposed for observability
+- **Future Scaling**: Can add Redis pub/sub for multi-instance deployments
+- **Heartbeat**: 30s ping/pong detects and cleans up dead connections
+
+## Testing Strategy
+
+### Unit Tests

+
+```typescript
+describe('WebSocket Message Creators', () => {
+  it('should create valid deal notification messages', () => { ... });
+  it('should generate valid ISO timestamps', () => { ... });
+});
+```
+
+### Integration Tests
+
+Future work: Add integration tests that:
+
+- Connect WebSocket clients to test server

+# ADR-023: Database Normalization and Referential Integrity
+
+**Date:** 2026-01-19
+**Status:** Accepted
+**Context:** API design violates database normalization principles
+
+## Problem Statement
+
+The application's API layer currently accepts string-based references (category names) instead of numerical IDs when creating relationships between entities. This violates database normalization principles and creates a brittle, error-prone API contract.
+
+**Example of Current Problem:**
+
+```typescript
+// API accepts string:
+POST /api/users/watched-items
+{ "itemName": "Milk", "category": "Dairy & Eggs" }  // ❌ String reference
+
+// But database uses normalized foreign keys:
+CREATE TABLE master_grocery_items (
+  category_id BIGINT REFERENCES categories(category_id)  -- ✅ Proper FK
+)
+```
+
+This mismatch forces the service layer to perform string lookups on every request:
+
+```typescript
+// Service must do string matching:
+const categoryRes = await client.query(
+  'SELECT category_id FROM categories WHERE name = $1',
+  [categoryName], // ❌ Error-prone string matching
+);
+```
+
+## Database Normal Forms (In Order of Importance)
+
+### 1. First Normal Form (1NF) ✅ Currently Satisfied
+
+**Rule:** Each column contains atomic values; no repeating groups.
+
+**Status:** ✅ **Compliant**
+
+- All columns contain single values
+- No arrays or delimited strings in columns
+- Each row is uniquely identifiable
+
+**Example:**
+
+```sql
+-- ✅ Good: Atomic values
+CREATE TABLE master_grocery_items (
+  master_grocery_item_id BIGINT PRIMARY KEY,
+  name TEXT,
+  category_id BIGINT
+);
+
+-- ❌ Bad: Non-atomic values (violates 1NF)
+CREATE TABLE items (
+  id BIGINT,
+  categories TEXT  -- "Dairy,Frozen,Snacks" (comma-delimited)
+);
+```
+
+### 2. Second Normal Form (2NF) ✅ Currently Satisfied
+
+**Rule:** No partial dependencies; all non-key columns depend on the entire primary key.
+
+**Status:** ✅ **Compliant**
+
+- All tables use single-column primary keys (no composite keys)
+- All non-key columns depend on the entire primary key
+
+**Example:**
+
+```sql
+-- ✅ Good: All columns depend on full primary key
+CREATE TABLE flyer_items (
+  flyer_item_id BIGINT PRIMARY KEY,
+  flyer_id BIGINT,           -- Depends on flyer_item_id
+  master_item_id BIGINT,     -- Depends on flyer_item_id
+  price_in_cents INT         -- Depends on flyer_item_id
+);
+
+-- ❌ Bad: Partial dependency (violates 2NF)
+CREATE TABLE flyer_items (
+  flyer_id BIGINT,
+  item_id BIGINT,
+  store_name TEXT,    -- Depends only on flyer_id, not (flyer_id, item_id)
+  PRIMARY KEY (flyer_id, item_id)
+);
+```
+
+### 3. Third Normal Form (3NF) ⚠️ VIOLATED IN API LAYER
+
+**Rule:** No transitive dependencies; non-key columns depend only on the primary key, not on other non-key columns.
+
+**Status:** ⚠️ **Database is compliant, but API layer violates this principle**
+
+**Database Schema (Correct):**
+
+```sql
+-- ✅ Categories are normalized
+CREATE TABLE categories (
+  category_id BIGINT PRIMARY KEY,
+  name TEXT NOT NULL UNIQUE
+);
+
+CREATE TABLE master_grocery_items (
+  master_grocery_item_id BIGINT PRIMARY KEY,
+  name TEXT,
+  category_id BIGINT REFERENCES categories(category_id)  -- Direct reference
+);
+```
+
+**API Layer (Violates 3NF Principle):**
+
+```typescript
+// ❌ API accepts category name instead of ID
+POST /api/users/watched-items
+{
+  "itemName": "Milk",
+  "category": "Dairy & Eggs"  // String! Should be category_id
+}
+
+// Service layer must denormalize by doing lookup:
+SELECT category_id FROM categories WHERE name = $1
+```
+
+This creates a **transitive dependency** in the application layer:
+
+- `watched_item` → `category_name` → `category_id`
+- Instead of direct: `watched_item` → `category_id`
+
+### 4. Boyce-Codd Normal Form (BCNF) ✅ Currently Satisfied
+
+**Rule:** Every determinant is a candidate key (stricter version of 3NF).
+
+**Status:** ✅ **Compliant**
+
+- All foreign key references use primary keys
+- No non-trivial functional dependencies where determinant is not a superkey
+
+### 5. Fourth Normal Form (4NF) ✅ Currently Satisfied
+
+**Rule:** No multi-valued dependencies; a record should not contain independent multi-valued facts.
+
+**Status:** ✅ **Compliant**
+
+- Junction tables properly separate many-to-many relationships
+- Examples: `user_watched_items`, `shopping_list_items`, `recipe_ingredients`
+
+### 6. Fifth Normal Form (5NF) ✅ Currently Satisfied
+
+**Rule:** No join dependencies; tables cannot be decomposed further without loss of information.
+
+**Status:** ✅ **Compliant** (as far as schema design goes)
+
+## Impact of API Violation
+
+### 1. Brittleness
+
+```typescript
+// Test fails because of exact string matching:
+addWatchedItem('Milk', 'Dairy'); // ❌ Fails - not exact match
+addWatchedItem('Milk', 'Dairy & Eggs'); // ✅ Works - exact match
+addWatchedItem('Milk', 'dairy & eggs'); // ❌ Fails - case sensitive
+```
+
+### 2. No Discovery Mechanism
+
+- No API endpoint to list available categories
+- Frontend cannot dynamically populate dropdowns
+- Clients must hardcode category names
+
+### 3. Performance Penalty
+
+```sql
+-- Current: String lookup on every request
+SELECT category_id FROM categories WHERE name = $1;  -- Full table scan or index scan
+
+-- Should be: Direct ID reference (no lookup needed)
+INSERT INTO master_grocery_items (name, category_id) VALUES ($1, $2);
+```
+
+### 4. Impossible Localization
+
+- Cannot translate category names without breaking API
+- Category names are hardcoded in English
+
+### 5. Maintenance Burden
+
+- Renaming a category breaks all API clients
+- Must coordinate name changes across frontend, tests, and documentation
+
+## Decision
+
+**We adopt the following principles for all API design:**
+
+### 1. Use Numerical IDs for All Foreign Key References
+
+**Rule:** APIs MUST accept numerical IDs when creating relationships between entities.
+
+```typescript
+// ✅ CORRECT: Use IDs
+POST /api/users/watched-items
+{
+  "itemName": "Milk",
+  "category_id": 3  // Numerical ID
+}
+
+// ❌ INCORRECT: Use strings
+POST /api/users/watched-items
+{
+  "itemName": "Milk",
+  "category": "Dairy & Eggs"  // String name
+}
+```
+
+### 2. Provide Discovery Endpoints
+
+**Rule:** For any entity referenced by ID, provide a GET endpoint to list available options.
+
+```typescript
+// Required: Category discovery endpoint
+GET / api / categories;
+Response: [
+  { category_id: 1, name: 'Fruits & Vegetables' },
+  { category_id: 2, name: 'Meat & Seafood' },
+  { category_id: 3, name: 'Dairy & Eggs' },
+];
+```
+
+### 3. Support Lookup by Name (Optional)
+
+**Rule:** If convenient, provide query parameters for name-based lookup, but use IDs internally.
+
+```typescript
+// Optional: Convenience endpoint
+GET /api/categories?name=Dairy%20%26%20Eggs
+Response: { "category_id": 3, "name": "Dairy & Eggs" }
+```
+
+### 4. Return Full Objects in Responses
+
+**Rule:** API responses SHOULD include denormalized data for convenience, but inputs MUST use IDs.
+
+```typescript
+// ✅ Response includes category details
+GET / api / users / watched - items;
+Response: [
+  {
+    master_grocery_item_id: 42,
+    name: 'Milk',
+    category_id: 3,
+    category: {
+      // ✅ Include full object in response
+      category_id: 3,
+      name: 'Dairy & Eggs',
+    },
+  },
+];
+```

+1. **User Watched Items** ([src/routes/user.routes.ts:76](../../src/routes/user.routes.ts))
+   - Currently: `category: string`
+   - Should be: `category_id: number`
+
+2. **Service Layer** ([src/services/db/personalization.db.ts:175](../../src/services/db/personalization.db.ts))
+   - Currently: `categoryName: string`
+   - Should be: `categoryId: number`
+
+3. **API Client** ([src/services/apiClient.ts:436](../../src/services/apiClient.ts))
+   - Currently: `category: string`
+   - Should be: `category_id: number`
+
+4. **Frontend Hooks** ([src/hooks/mutations/useAddWatchedItemMutation.ts:9](../../src/hooks/mutations/useAddWatchedItemMutation.ts))
+   - Currently: `category?: string`
+   - Should be: `category_id: number`
+
+### Potential Violations (Review Required)
+
+1. **UPC/Barcode System** ([src/types/upc.ts:85](../../src/types/upc.ts))
+   - Uses `category: string | null`
+   - May be appropriate if category is free-form user input
+
+2. **AI Extraction** ([src/types/ai.ts:21](../../src/types/ai.ts))
+   - Uses `category_name: z.string()`
+   - AI extracts category names, needs mapping to IDs
+
+3. **Flyer Data Transformer** ([src/services/flyerDataTransformer.ts:40](../../src/services/flyerDataTransformer.ts))
+   - Uses `category_name: string`
+   - May need category matching/creation logic
+
+## Migration Strategy
+
+See [research-category-id-migration.md](../research-category-id-migration.md) for detailed migration plan.
+
+**High-level approach:**
+
+1. **Phase 1: Add category discovery endpoint** (non-breaking)
+   - `GET /api/categories`
+   - No API changes yet
+
+2. **Phase 2: Support both formats** (non-breaking)
+   - Accept both `category` (string) and `category_id` (number)
+   - Deprecate string format with warning logs
+
+3. **Phase 3: Remove string support** (breaking change, major version bump)
+   - Only accept `category_id`
+   - Update all clients and tests
+
+## Consequences
+
+### Positive
+
+- ✅ API matches database schema design
+- ✅ More robust (no typo-based failures)
+- ✅ Better performance (no string lookups)
+- ✅ Enables localization
+- ✅ Discoverable via REST API
+- ✅ Follows REST best practices
+
+### Negative
+
+- ⚠️ Breaking change for existing API consumers
+- ⚠️ Requires client updates
+- ⚠️ More complex migration path
+
+### Neutral
+
+- Frontend must fetch categories before displaying form
+- Slightly more initial API calls (one-time category fetch)

+# ADR-040: Testing Economics and Priorities
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+## Context
+
+ADR-010 established the testing strategy and standards. However, it does not address the economic trade-offs of testing: when the cost of writing and maintaining tests exceeds their value. This document provides practical guidance on where to invest testing effort for maximum return.
+
+## Decision
+
+We adopt a **value-based testing approach** that prioritizes tests based on:
+
+1. Risk of the code path (what breaks if this fails?)
+2. Stability of the code (how often does this change?)
+3. Complexity of the logic (can a human easily verify correctness?)
+4. Cost of the test (setup complexity, execution time, maintenance burden)
+
+## Testing Investment Matrix
+
+| Test Type       | Investment Level    | When to Write                   | When to Skip                      |
+| --------------- | ------------------- | ------------------------------- | --------------------------------- |
+| **E2E**         | Minimal (5 tests)   | Critical user flows only        | Everything else                   |
+| **Integration** | Moderate (17 tests) | API contracts, auth, DB queries | Internal service wiring           |
+| **Unit**        | High (185+ tests)   | Business logic, utilities       | Defensive fallbacks, trivial code |
+
+## High-Value Tests (Always Write)
+
+### E2E Tests (Budget: 5-10 tests total)
+
+Write E2E tests for flows where failure means:
+
+- Users cannot sign up or log in
+- Users cannot complete the core value proposition (upload flyer → see deals)
+- Money or data is at risk
+
+**Current E2E coverage is appropriate:**
+
+- `auth.e2e.test.ts` - Registration, login, password reset
+- `flyer-upload.e2e.test.ts` - Complete upload pipeline
+- `user-journey.e2e.test.ts` - Full user workflow
+- `admin-authorization.e2e.test.ts` - Admin access control
+- `admin-dashboard.e2e.test.ts` - Admin operations
+
+**Do NOT add E2E tests for:**
+
+- UI variations or styling
+- Edge cases (handle in unit tests)
+- Features that can be tested faster at a lower level
+
+### Integration Tests (Budget: 15-25 tests)
+
+Write integration tests for:
+
+- Every public API endpoint (contract testing)
+- Authentication and authorization flows
+- Database queries that involve joins or complex logic
+- Middleware behavior (rate limiting, validation)
+
+**Current integration coverage is appropriate:**
+
+- Auth, admin, user routes
+- Flyer processing pipeline
+- Shopping lists, budgets, recipes
+- Gamification and notifications
+
+**Do NOT add integration tests for:**
+
+- Internal service-to-service calls (mock at boundaries)
+- Simple CRUD operations (test the repository pattern once)
+- UI components (use unit tests)
+
+### Unit Tests (Budget: Proportional to complexity)
+
+Write unit tests for:
+
+- **Pure functions and utilities** - High value, easy to test
+- **Business logic in services** - Medium-high value
+- **React components** - Rendering, user interactions, state changes
+- **Custom hooks** - Data transformation, side effects
+- **Validators and parsers** - Edge cases matter here
+
+## Low-Value Tests (Skip or Defer)
+
+### Tests That Cost More Than They're Worth
+
+1. **Defensive fallback code protected by types**
+
+   ```typescript
+   // This fallback can never execute if types are correct
+   const name = store.name || 'Unknown'; // store.name is required
+   ```
+
+   - If you need `as any` to test it, the type system already prevents it
+   - Either remove the fallback or accept the coverage gap
+
+2. **Switch/case default branches for exhaustive enums**
+
+   ```typescript
+   switch (status) {
+     case 'pending':
+       return 'yellow';
+     case 'complete':
+       return 'green';
+     default:
+       return ''; // TypeScript prevents this
+   }
+   ```
+
+   - The default exists for safety, not for execution
+   - Don't test impossible states
+
+3. **Trivial component variations**
+   - Testing every tab in a tab panel when they share logic
+   - Testing loading states that just show a spinner
+   - Testing disabled button states (test the logic that disables, not the disabled state)
+
+4. **Tests requiring excessive mock setup**
+   - If test setup is longer than test assertions, reconsider
+   - Per ADR-010: "Excessive mock setup" is a code smell
+
+5. **Framework behavior verification**
+   - React rendering, React Query caching, Router navigation
+   - Trust the framework; test your code
+
+### Coverage Gaps to Accept
+
+The following coverage gaps are acceptable and should NOT be closed with tests:
+
+| Pattern                                    | Reason                    | Alternative                   |
+| ------------------------------------------ | ------------------------- | ----------------------------- |
+| `value \|\| 'default'` for required fields | Type system prevents      | Remove fallback or accept gap |
+| `catch (error) { ... }` for typed APIs     | Error types are known     | Test the expected error types |
+| `default:` in exhaustive switches          | TypeScript exhaustiveness | Accept gap                    |
+| Logging statements                         | Observability, not logic  | No test needed                |
+| Feature flags / environment checks         | Tested by deployment      | Config tests if complex       |
+
+## Time Budget Guidelines
+
+For a typical feature (new API endpoint + UI):
+
+| Activity                                | Time Budget | Notes                                 |
+| --------------------------------------- | ----------- | ------------------------------------- |
+| Unit tests (component + hook + utility) | 30-45 min   | Write alongside code                  |
+| Integration test (API contract)         | 15-20 min   | One test per endpoint                 |
+| E2E test                                | 0 min       | Only for critical paths               |
+| Total testing overhead                  | ~1 hour     | Should not exceed implementation time |
+
+**Rule of thumb**: If testing takes longer than implementation, you're either:
+
+1. Testing too much
+2. Writing tests that are too complex
+3. Testing code that should be refactored
+
+## Coverage Targets
+
+We explicitly reject arbitrary coverage percentage targets. Instead:
+
+| Metric                 | Target          | Rationale                              |
+| ---------------------- | --------------- | -------------------------------------- |
+| Statement coverage     | No target       | High coverage ≠ quality tests          |
+| Branch coverage        | No target       | Many branches are defensive/impossible |
+| E2E test count         | 5-10            | Critical paths only                    |
+| Integration test count | 15-25           | API contracts                          |
+| Unit test files        | 1:1 with source | Colocated, proportional                |
+
+## When to Add Tests to Existing Code
+
+Add tests when:
+
+1. **Fixing a bug** - Add a test that would have caught it
+2. **Refactoring** - Add tests before changing behavior
+3. **Code review feedback** - Reviewer identifies risk
+4. **Production incident** - Prevent recurrence
+
+Do NOT add tests:
+
+1. To increase coverage percentages
+2. For code that hasn't changed in 6+ months
+3. For code scheduled for deletion/replacement
+
+## Consequences
+
+**Positive:**
+
+- Testing effort focuses on high-risk, high-value code
+- Developers spend less time on low-value tests
+- Test suite runs faster (fewer unnecessary tests)
+- Maintenance burden decreases
+
+**Negative:**
+
+- Some defensive code paths remain untested
+- Coverage percentages may not satisfy external audits
+- Requires judgment calls that may be inconsistent

+- `vitest.config.ts` - Coverage configuration
+- `src/tests/` - Test utilities and setup
+
+## Review Checklist
+
+Before adding a new test, ask:
+
+1. [ ] What user-visible behavior does this test protect?
+2. [ ] Can this be tested at a lower level (unit vs integration)?
+3. [ ] Does this test require `as any` or mock gymnastics?
+4. [ ] Will this test break when implementation changes (brittle)?
+5. [ ] Is the test setup simpler than the code being tested?
+
+If any answer suggests low value, skip the test or simplify.

+# ADR-041: AI/Gemini Integration Architecture
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-09
+
+## Context
+
+The application relies heavily on Google Gemini AI for core functionality:
+
+1. **Flyer Processing**: Extracting store names, dates, addresses, and individual sale items from uploaded flyer images.
+2. **Receipt Analysis**: Parsing purchased items and prices from receipt images.
+3. **Recipe Suggestions**: Generating recipe ideas based on available ingredients.
+4. **Text Extraction**: OCR-style extraction from cropped image regions.
+
+These AI operations have unique challenges:
+
+- **Rate Limits**: Google AI API enforces requests-per-minute (RPM) limits.
+- **Quota Buckets**: Different model families (stable, preview, experimental) have separate quotas.
+- **Model Availability**: Models may be unavailable due to regional restrictions, updates, or high load.
+- **Cost Variability**: Different models have different pricing (Flash-Lite vs Pro).
+- **Output Limits**: Some models have 8k token limits, others 65k.
+- **Testability**: Tests must not make real API calls.
+
+## Decision
+
+We will implement a centralized `AIService` class with:
+
+1. **Dependency Injection**: AI client and filesystem are injectable for testability.
+2. **Model Fallback Chain**: Automatic failover through prioritized model lists.
+3. **Rate Limiting**: Per-instance rate limiter using `p-ratelimit`.
+4. **Tiered Model Selection**: Different model lists for different task types.
+5. **Environment-Aware Mocking**: Automatic mock client in test environments.
+
+### Design Principles
+
+- **Single Responsibility**: `AIService` handles all AI interactions.
+- **Fail-Safe Fallbacks**: If a model fails, try the next one in the chain.
+- **Cost Optimization**: Use cheaper "lite" models for simple text tasks.
+- **Structured Logging**: Log all AI interactions with timing and model info.
+
+## Implementation Details
+
+### AIService Class Structure
+
+Located in `src/services/aiService.server.ts`:
+
+```typescript
+interface IAiClient {
+  generateContent(request: {
+    contents: Content[];
+    tools?: Tool[];
+    useLiteModels?: boolean;
+  }): Promise<GenerateContentResponse>;
+}
+
+interface IFileSystem {
+  readFile(path: string): Promise<Buffer>;
+}
+
+export class AIService {
+  private aiClient: IAiClient;
+  private fs: IFileSystem;
+  private rateLimiter: <T>(fn: () => Promise<T>) => Promise<T>;
+  private logger: Logger;
+
+  constructor(logger: Logger, aiClient?: IAiClient, fs?: IFileSystem) {
+    // If aiClient provided: use it (unit test)
+    // Else if test environment: use internal mock (integration test)
+    // Else: create real GoogleGenAI client (production)
+  }
+}
+```
+
+### Tiered Model Lists
+
+Models are organized by task complexity and quota bucket:
+
+```typescript
+// For image processing (vision + long output)
+private readonly models = [
+  // Tier A: Fast & Stable
+  'gemini-2.5-flash',      // Primary, 65k output
+  'gemini-2.5-flash-lite', // Cost-saver, 65k output
+
+  // Tier B: Heavy Lifters
+  'gemini-2.5-pro',        // Complex layouts, 65k output
+
+  // Tier C: Preview Bucket (separate quota)
+  'gemini-3-flash-preview',
+  'gemini-3-pro-preview',
+
+  // Tier D: Experimental Bucket
+  'gemini-exp-1206',
+
+  // Tier E: Last Resort
+  'gemma-3-27b-it',
+  'gemini-2.0-flash-exp',  // WARNING: 8k limit
+];
+
+// For simple text tasks (recipes, categorization)
+private readonly models_lite = [
+  'gemini-2.5-flash-lite',
+  'gemini-2.0-flash-lite-001',
+  'gemini-2.0-flash-001',
+  'gemma-3-12b-it',
+  'gemma-3-4b-it',
+  'gemini-2.0-flash-exp',
+];
+```
+
+### Fallback with Retry Logic
+
+```typescript
+private async _generateWithFallback(
+  genAI: GoogleGenAI,
+  request: { contents: Content[]; tools?: Tool[] },
+  models: string[],
+): Promise<GenerateContentResponse> {
+  let lastError: Error | null = null;
+
+  for (const modelName of models) {
+    try {
+      return await genAI.models.generateContent({ model: modelName, ...request });
+    } catch (error: unknown) {
+      const errorMsg = extractErrorMessage(error);
+      const isRetriable = [
+        'quota', '429', '503', 'resource_exhausted',
+        'overloaded', 'unavailable', 'not found'
+      ].some(term => errorMsg.toLowerCase().includes(term));
+
+      if (isRetriable) {
+        this.logger.warn(`Model '${modelName}' failed, trying next...`);
+        lastError = new Error(errorMsg);
+        continue;
+      }
+      throw error; // Non-retriable error
+    }
+  }
+  throw lastError || new Error('All AI models failed.');
+}
+```
+
+### Rate Limiting
+
+```typescript
+const requestsPerMinute = parseInt(process.env.GEMINI_RPM || '5', 10);
+this.rateLimiter = pRateLimit({
+  interval: 60 * 1000,
+  rate: requestsPerMinute,
+  concurrency: requestsPerMinute,
+});
+
+// Usage:
+const result = await this.rateLimiter(() =>
+  this.aiClient.generateContent({ contents: [...] })
+);
+```
+
+### Test Environment Detection
+
+```typescript
+const isTestEnvironment = process.env.NODE_ENV === 'test' || !!process.env.VITEST_POOL_ID;
+
+if (aiClient) {
+  // Unit test: use provided mock
+  this.aiClient = aiClient;
+} else if (isTestEnvironment) {
+  // Integration test: use internal mock
+  this.aiClient = {
+    generateContent: async () => ({
+      text: JSON.stringify(this.getMockFlyerData()),
+    }),
+  };
+} else {
+  // Production: use real client
+  const genAI = new GoogleGenAI({ apiKey: process.env.GEMINI_API_KEY });
+  this.aiClient = { generateContent: /* adapter */ };
+}
+```
+
+### Prompt Engineering
+
+Prompts are constructed with:
+
+1. **Clear Task Definition**: What to extract and in what format.
+2. **Structured Output Requirements**: JSON schema with field descriptions.
+3. **Examples**: Concrete examples of expected output.
+4. **Context Hints**: User location for store address resolution.
+
+```typescript
+private _buildFlyerExtractionPrompt(
+  masterItems: MasterGroceryItem[],
+  submitterIp?: string,
+  userProfileAddress?: string,
+): string {
+  // Location hint for address resolution
+  let locationHint = '';
+  if (userProfileAddress) {
+    locationHint = `The user has profile address "${userProfileAddress}"...`;
+  }
+
+  // Simplified master item list (reduce token usage)
+  const simplifiedMasterList = masterItems.map(item => ({
+    id: item.master_grocery_item_id,
+    name: item.name,
+  }));
+
+  return `
+    # TASK
+    Analyze the flyer image(s) and extract...
+
+    # RULES
+    1. Extract store_name, valid_from, valid_to, store_address
+    2. Extract items array with item, price_display, price_in_cents...
+
+    # EXAMPLES
+    - { "item": "Red Grapes", "price_display": "$1.99 /lb", ... }
+
+    # MASTER LIST
+    ${JSON.stringify(simplifiedMasterList)}
+  `;
+}
+```
+
+### Response Parsing
+
+AI responses may contain markdown, trailing text, or formatting issues:
+
+````typescript
+private _parseJsonFromAiResponse<T>(responseText: string | undefined, logger: Logger): T | null {
+  if (!responseText) return null;
+
+  // Try to extract from markdown code block
+  const markdownMatch = responseText.match(/```(json)?\s*([\s\S]*?)\s*```/);
+  let jsonString = markdownMatch?.[2]?.trim() || responseText;
+
+  // Find JSON boundaries
+  const startIndex = Math.min(
+    jsonString.indexOf('{') >= 0 ? jsonString.indexOf('{') : Infinity,
+    jsonString.indexOf('[') >= 0 ? jsonString.indexOf('[') : Infinity
+  );
+  const endIndex = Math.max(jsonString.lastIndexOf('}'), jsonString.lastIndexOf(']'));
+
+  if (startIndex === Infinity || endIndex === -1) return null;
+
+  try {
+    return JSON.parse(jsonString.substring(startIndex, endIndex + 1));
+  } catch {
+    return null;
+  }
+}
+````
+
+## Consequences
+
+### Positive
+
+- **Resilience**: Automatic failover when models are unavailable or rate-limited.
+- **Cost Control**: Uses cheaper models for simple tasks.
+- **Testability**: Full mock support for unit and integration tests.
+- **Observability**: Detailed logging of all AI operations with timing.
+- **Maintainability**: Centralized AI logic in one service.
+
+### Negative
+
+- **Model List Maintenance**: Must update model lists when new models release.
+- **Complexity**: Fallback logic adds complexity.
+- **Delayed Failures**: May take longer to fail if all models are down.
+
+### Mitigation
+
+- Monitor model deprecation announcements from Google.
+- Add health checks that validate AI connectivity on startup.
+- Consider caching successful model selections per task type.

+# ADR-042: Email and Notification Architecture
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-09
+
+## Context
+
+The application sends emails for multiple purposes:
+
+1. **Transactional Emails**: Password reset, welcome emails, account verification.
+2. **Deal Notifications**: Alerting users when watched items go on sale.
+3. **Bulk Communications**: System announcements, marketing (future).
+
+Email delivery has unique challenges:
+
+- **Reliability**: Emails must be delivered even if the main request fails.
+- **Rate Limits**: SMTP servers enforce sending limits.
+- **Retry Logic**: Failed emails should be retried with backoff.
+- **Templating**: Emails need consistent branding and formatting.
+- **Testing**: Tests should not send real emails.
+
+## Decision
+
+We will implement a queue-based email system using:
+
+1. **Nodemailer**: For SMTP transport and email composition.
+2. **BullMQ**: For job queuing, retry logic, and rate limiting.
+3. **Dedicated Worker**: Background process for email delivery.
+4. **Structured Logging**: Job-scoped logging for debugging.
+
+### Design Principles
+
+- **Asynchronous Delivery**: Queue emails immediately, deliver asynchronously.
+- **Idempotent Jobs**: Jobs can be retried safely.
+- **Separation of Concerns**: Email composition separate from delivery.
+- **Environment-Aware**: Disable real sending in test environments.
+
+## Implementation Details
+
+### Email Service Structure
+
+Located in `src/services/emailService.server.ts`:
+
+```typescript
+import nodemailer from 'nodemailer';
+import type { Job } from 'bullmq';
+import type { Logger } from 'pino';
+
+// SMTP transporter configured from environment
+const transporter = nodemailer.createTransport({
+  host: process.env.SMTP_HOST,
+  port: parseInt(process.env.SMTP_PORT || '587', 10),
+  secure: process.env.SMTP_SECURE === 'true',
+  auth: {
+    user: process.env.SMTP_USER,
+    pass: process.env.SMTP_PASS,
+  },
+});
+```
+
+### Email Job Data Structure
+
+```typescript
+// src/types/job-data.ts
+export interface EmailJobData {
+  to: string;
+  subject: string;
+  text: string;
+  html: string;
+}
+```
+
+### Core Send Function
+
+```typescript
+export const sendEmail = async (options: EmailJobData, logger: Logger) => {

+
+### Job Processor
+
+```typescript

+    throw wrappedError; // BullMQ will retry
+  }
+};
+```
+
+### Specialized Email Functions
+
+#### Password Reset
+
+```typescript

+      </li>
+    `,
+    )
+    .join('');
+
+  const html = `
+    <h1>Hi ${name || 'there'},</h1>
+    <p>We found great deals on items you're watching:</p>
+    <ul>${dealsListHtml}</ul>
+    <p>Check them out on the deals page!</p>
+  `;
+
+  await sendEmail({ to, subject: 'New Deals Found!', text: '...', html }, logger);
+};
+```
+
+### Queue Configuration
+
+Located in `src/services/queueService.server.ts`:
+
+```typescript
+import { Queue, Worker, Job } from 'bullmq';
+import { processEmailJob } from './emailService.server';
+
+export const emailQueue = new Queue<EmailJobData>('email', {
+  connection: redisConnection,
+  defaultJobOptions: {
+    attempts: 3,
+    backoff: {
+      type: 'exponential',
+      delay: 1000,
+    },
+    removeOnComplete: 100,
+    removeOnFail: 500,
+  },
+});
+
+// Worker to process email jobs
+const emailWorker = new Worker('email', processEmailJob, {
+  connection: redisConnection,
+  concurrency: 5,
+});
+```
+
+### Enqueueing Emails
+
+```typescript
+// From backgroundJobService.ts
+await emailQueue.add('deal-notification', {
+  to: user.email,
+  subject: 'New Deals Found!',
+  text: textContent,
+  html: htmlContent,
+});
+```
+
+### Background Job Integration
+
+Located in `src/services/backgroundJobService.ts`:
+
+```typescript
+export class BackgroundJobService {
+  constructor(
+    private personalizationRepo: PersonalizationRepository,
+    private notificationRepo: NotificationRepository,
+    private emailQueue: Queue<EmailJobData>,
+    private logger: Logger,
+  ) {}
+
+  async runDailyDealCheck(): Promise<void> {
+    this.logger.info('Starting daily deal check...');
+
+    const deals = await this.personalizationRepo.getBestSalePricesForAllUsers(this.logger);
+
+    for (const userDeals of deals) {
+      await this.emailQueue.add('deal-notification', {
+        to: userDeals.email,
+        subject: 'New Deals Found!',
+        text: '...',
+        html: '...',
+      });
+    }
+  }
+}
+```
+
+## Environment Variables
+
+```bash
+# SMTP Configuration
+SMTP_HOST=smtp.example.com
+SMTP_PORT=587
+SMTP_SECURE=false
+SMTP_USER=user@example.com
+SMTP_PASS=secret
+SMTP_FROM_EMAIL=noreply@flyer-crawler.com
+
+# Frontend URL for email links
+FRONTEND_URL=https://flyer-crawler.com
+```
+
+## Consequences
+
+### Positive
+
+- **Reliability**: Failed emails are automatically retried with exponential backoff.
+- **Scalability**: Queue can handle burst traffic without overwhelming SMTP.
+- **Observability**: Job-scoped logging enables easy debugging.
+- **Separation**: Email composition is decoupled from delivery timing.
+- **Testability**: Can mock the queue or use Ethereal for testing.
+
+### Negative
+
+- **Complexity**: Adds queue infrastructure dependency (Redis).
+- **Delayed Delivery**: Emails are not instant (queued first).
+- **Monitoring Required**: Need to monitor queue depth and failure rates.
+
+### Mitigation
+
+- Use Bull Board UI for queue monitoring (already implemented).
+- Set up alerts for queue depth and failure rate thresholds.
+- Consider Ethereal or MailHog for development/testing.
+
+## Testing Strategy
+
+```typescript
+// Unit test with mocked queue
+const mockEmailQueue = {
+  add: vi.fn().mockResolvedValue({ id: 'job-1' }),
+};
+
+const service = new BackgroundJobService(
+  mockPersonalizationRepo,
+  mockNotificationRepo,
+  mockEmailQueue as any,
+  mockLogger,
+);
+
+await service.runDailyDealCheck();
+expect(mockEmailQueue.add).toHaveBeenCalledWith('deal-notification', expect.any(Object));
+```

+# ADR-043: Express Middleware Pipeline Architecture
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-09
+
+## Context
+
+The Express application uses a layered middleware pipeline to handle cross-cutting concerns:
+
+1. **Security**: Helmet headers, CORS, rate limiting.
+2. **Parsing**: JSON body, URL-encoded, cookies.
+3. **Authentication**: Session management, JWT verification.
+4. **Validation**: Request body/params validation.
+5. **File Handling**: Multipart form data, file uploads.
+6. **Error Handling**: Centralized error responses.
+
+Middleware ordering is critical - incorrect ordering can cause security vulnerabilities or broken functionality. This ADR documents the canonical middleware order and patterns.
+
+## Decision
+
+We will establish a strict middleware ordering convention:
+
+1. **Security First**: Security headers and protections apply to all requests.
+2. **Parsing Before Logic**: Body/cookie parsing before route handlers.
+3. **Auth Before Routes**: Authentication middleware before protected routes.
+4. **Validation At Route Level**: Per-route validation middleware.
+5. **Error Handler Last**: Centralized error handling catches all errors.
+
+### Design Principles
+
+- **Defense in Depth**: Multiple security layers.
+- **Fail-Fast**: Reject bad requests early in the pipeline.
+- **Explicit Ordering**: Document and enforce middleware order.
+- **Route-Level Flexibility**: Specific middleware per route as needed.
+
+## Implementation Details
+
+### Global Middleware Order
+
+Located in `src/server.ts`:
+
+```typescript
+import express from 'express';
+import helmet from 'helmet';
+import cors from 'cors';
+import cookieParser from 'cookie-parser';
+import { requestTimeoutMiddleware } from './middleware/timeout.middleware';
+import { rateLimiter } from './middleware/rateLimit.middleware';
+import { errorHandler } from './middleware/errorHandler.middleware';
+
+const app = express();
+
+// ============================================
+// LAYER 1: Security Headers & Protections
+// ============================================
+app.use(
+  helmet({
+    contentSecurityPolicy: {
+      directives: {
+        defaultSrc: ["'self'"],
+        scriptSrc: ["'self'", "'unsafe-inline'"],
+        styleSrc: ["'self'", "'unsafe-inline'"],
+        imgSrc: ["'self'", 'data:', 'blob:'],
+      },
+    },
+  }),
+);
+app.use(
+  cors({
+    origin: process.env.FRONTEND_URL,
+    credentials: true,
+  }),
+);
+
+// ============================================
+// LAYER 2: Request Limits & Timeouts
+// ============================================
+app.use(requestTimeoutMiddleware(30000)); // 30s default
+app.use(rateLimiter); // Rate limiting per IP
+
+// ============================================
+// LAYER 3: Body & Cookie Parsing
+// ============================================
+app.use(express.json({ limit: '10mb' }));
+app.use(express.urlencoded({ extended: true, limit: '10mb' }));
+app.use(cookieParser());
+
+// ============================================
+// LAYER 4: Static Assets (before auth)
+// ============================================
+app.use('/flyer-images', express.static('flyer-images'));
+
+// ============================================
+// LAYER 5: Authentication Setup
+// ============================================
+app.use(passport.initialize());
+app.use(passport.session());
+
+// ============================================
+// LAYER 6: Routes (with per-route middleware)
+// ============================================
+app.use('/api/auth', authRoutes);
+app.use('/api/flyers', flyerRoutes);
+app.use('/api/admin', adminRoutes);
+// ... more routes
+
+// ============================================
+// LAYER 7: Error Handling (must be last)
+// ============================================
+app.use(errorHandler);
+```
+
+### Validation Middleware
+
+Located in `src/middleware/validation.middleware.ts`:
+
+```typescript
+import { z } from 'zod';
+import { Request, Response, NextFunction } from 'express';
+import { ValidationError } from '../services/db/errors.db';
+
+export const validate = <T extends z.ZodType>(schema: T) => {
+  return (req: Request, res: Response, next: NextFunction) => {
+    const result = schema.safeParse({
+      body: req.body,
+      query: req.query,
+      params: req.params,
+    });
+
+    if (!result.success) {
+      const errors = result.error.errors.map((err) => ({
+        path: err.path.join('.'),
+        message: err.message,
+      }));
+      return next(new ValidationError(errors));
+    }
+
+    // Attach validated data to request
+    req.validated = result.data;
+    next();
+  };
+};
+
+// Usage in routes:
+router.post('/flyers', authenticate, validate(CreateFlyerSchema), flyerController.create);
+```
+
+### File Upload Middleware
+
+Located in `src/middleware/fileUpload.middleware.ts`:
+
+```typescript
+import multer from 'multer';
+import path from 'path';
+import { v4 as uuidv4 } from 'uuid';
+
+const storage = multer.diskStorage({
+  destination: (req, file, cb) => {
+    cb(null, 'flyer-images/');
+  },
+  filename: (req, file, cb) => {
+    const ext = path.extname(file.originalname);
+    cb(null, `${uuidv4()}${ext}`);
+  },
+});
+
+const fileFilter = (req: Request, file: Express.Multer.File, cb: multer.FileFilterCallback) => {
+  const allowedTypes = ['image/jpeg', 'image/png', 'image/webp', 'application/pdf'];
+  if (allowedTypes.includes(file.mimetype)) {
+    cb(null, true);
+  } else {
+    cb(new Error('Invalid file type'));
+  }
+};
+
+export const uploadFlyer = multer({
+  storage,
+  fileFilter,
+  limits: {
+    fileSize: 10 * 1024 * 1024, // 10MB
+    files: 10, // Max 10 files per request
+  },
+});
+
+// Usage:
+router.post('/flyers/upload', uploadFlyer.array('files', 10), flyerController.upload);
+```
+
+### Authentication Middleware
+
+Located in `src/middleware/auth.middleware.ts`:
+
+```typescript
+import passport from 'passport';
+import { Request, Response, NextFunction } from 'express';
+
+// Require authenticated user
+export const authenticate = (req: Request, res: Response, next: NextFunction) => {
+  passport.authenticate('jwt', { session: false }, (err, user) => {
+    if (err) return next(err);
+    if (!user) {
+      return res.status(401).json({ error: 'Unauthorized' });
+    }
+    req.user = user;
+    next();
+  })(req, res, next);
+};
+
+// Require admin role
+export const requireAdmin = (req: Request, res: Response, next: NextFunction) => {
+  if (!req.user?.role || req.user.role !== 'admin') {
+    return res.status(403).json({ error: 'Forbidden' });
+  }
+  next();
+};
+
+// Optional auth (attach user if present, continue if not)
+export const optionalAuth = (req: Request, res: Response, next: NextFunction) => {
+  passport.authenticate('jwt', { session: false }, (err, user) => {
+    if (user) req.user = user;
+    next();
+  })(req, res, next);
+};
+```
+
+### Error Handler Middleware
+
+Located in `src/middleware/errorHandler.middleware.ts`:
+
+```typescript
+import { Request, Response, NextFunction } from 'express';
+import { v4 as uuidv4 } from 'uuid';
+import { logger } from '../services/logger.server';
+import { ValidationError, NotFoundError, UniqueConstraintError } from '../services/db/errors.db';
+
+export const errorHandler = (err: Error, req: Request, res: Response, next: NextFunction) => {
+  const errorId = uuidv4();
+
+  // Log error with context
+  logger.error(
+    {
+      errorId,
+      err,
+      path: req.path,
+      method: req.method,
+      userId: req.user?.user_id,
+    },
+    'Request error',
+  );
+
+  // Map error types to HTTP responses
+  if (err instanceof ValidationError) {
+    return res.status(400).json({
+      success: false,
+      error: { code: 'VALIDATION_ERROR', message: err.message, details: err.errors },
+      meta: { errorId },
+    });
+  }
+
+  if (err instanceof NotFoundError) {
+    return res.status(404).json({
+      success: false,
+      error: { code: 'NOT_FOUND', message: err.message },
+      meta: { errorId },
+    });
+  }
+
+  if (err instanceof UniqueConstraintError) {
+    return res.status(409).json({
+      success: false,
+      error: { code: 'CONFLICT', message: err.message },
+      meta: { errorId },
+    });
+  }
+
+  // Default: Internal Server Error
+  return res.status(500).json({
+    success: false,
+    error: {
+      code: 'INTERNAL_ERROR',
+      message: process.env.NODE_ENV === 'production' ? 'An unexpected error occurred' : err.message,
+    },
+    meta: { errorId },
+  });
+};
+```
+
+### Request Timeout Middleware
+
+```typescript
+export const requestTimeoutMiddleware = (timeout: number) => {
+  return (req: Request, res: Response, next: NextFunction) => {
+    res.setTimeout(timeout, () => {
+      if (!res.headersSent) {
+        res.status(503).json({
+          success: false,
+          error: { code: 'TIMEOUT', message: 'Request timed out' },
+        });
+      }
+    });
+    next();
+  };
+};
+```
+
+## Route-Level Middleware Patterns
+
+### Protected Route with Validation
+
+```typescript
+router.put(
+  '/flyers/:flyerId',
+  authenticate, // 1. Auth check
+  validate(UpdateFlyerSchema), // 2. Input validation
+  flyerController.update, // 3. Handler
+);
+```
+
+### Admin-Only Route
+
+```typescript
+router.delete(
+  '/admin/users/:userId',
+  authenticate, // 1. Auth check
+  requireAdmin, // 2. Role check
+  validate(DeleteUserSchema), // 3. Input validation
+  adminController.deleteUser, // 4. Handler
+);
+```
+
+### File Upload Route
+
+```typescript
+router.post(
+  '/flyers/upload',
+  authenticate, // 1. Auth check
+  uploadFlyer.array('files', 10), // 2. File handling
+  validate(UploadFlyerSchema), // 3. Metadata validation
+  flyerController.upload, // 4. Handler
+);
+```
+
+### Public Route with Optional Auth
+
+```typescript
+router.get(
+  '/flyers/:flyerId',
+  optionalAuth, // 1. Attach user if present
+  flyerController.getById, // 2. Handler (can check req.user)
+);
+```
+
+## Consequences
+
+### Positive
+
+- **Security**: Defense-in-depth with multiple security layers.
+- **Consistency**: Predictable request processing order.
+- **Maintainability**: Clear separation of concerns.
+- **Debuggability**: Errors caught and logged centrally.
+- **Flexibility**: Per-route middleware composition.
+
+### Negative
+
+- **Order Sensitivity**: Middleware order bugs can be subtle.
+- **Performance**: Many middleware layers add latency.
+- **Complexity**: New developers must understand the pipeline.
+
+### Mitigation
+
+- Document middleware order in comments (as shown above).
+- Use integration tests that verify middleware chain behavior.
+- Profile middleware performance in production.

+# ADR-044: Frontend Feature Organization Pattern
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-09
+
+## Context
+
+The React frontend has grown to include multiple distinct features:
+
+- Flyer viewing and management
+- Shopping list creation
+- Budget tracking and charts
+- Voice assistant
+- User personalization
+- Admin dashboard
+
+Without clear organization, code becomes scattered across generic folders (`/components`, `/hooks`, `/utils`), making it hard to:
+
+1. Understand feature boundaries
+2. Find related code
+3. Refactor or remove features
+4. Onboard new developers
+
+## Decision
+
+We will adopt a **feature-based folder structure** where each major feature is self-contained in its own directory under `/features`. Shared code lives in dedicated top-level folders.
+
+### Design Principles
+
+- **Colocation**: Keep related code together (components, hooks, types, utils).
+- **Feature Independence**: Features should minimize cross-dependencies.
+- **Shared Extraction**: Only extract to shared folders when truly reused.
+- **Flat Within Features**: Avoid deep nesting within feature folders.

+└── index.ts                   # Public API of the feature
+```
+
+### Feature Index File
+
+Each feature has an `index.ts` that defines its public API:
+
+```typescript
+// features/flyer/index.ts
+export { FlyerCard, FlyerGrid, FlyerUploader } from './components';
+export { useFlyerDetails, useFlyerUpload } from './hooks';
+export type { FlyerViewProps, FlyerUploadState } from './types';
+```
+
+### Import Patterns
+
+```typescript
+// Importing from a feature (preferred)
+import { FlyerCard, useFlyerDetails } from '@/features/flyer';
+
+// Importing shared components
+import { Button, Card } from '@/components/ui';
+import { useDebounce } from '@/hooks/utils';
+
+// Avoid: reaching into feature internals
+// import { FlyerCard } from '@/features/flyer/components/FlyerCard';
+```
+
+### Provider Organization
+
+Located in `src/providers/`:
+
+```typescript
+// AppProviders.tsx - Composes all providers
+export function AppProviders({ children }: { children: React.ReactNode }) {
+  return (
+    <QueryClientProvider client={queryClient}>
+      <AuthProvider>
+        <UserDataProvider>
+          <FlyersProvider>
+            <ThemeProvider>
+              {children}
+            </ThemeProvider>
+          </FlyersProvider>
+        </UserDataProvider>
+      </AuthProvider>
+    </QueryClientProvider>
+  );
+}
+```
+
+### Query/Mutation Hook Organization
+
+Located in `src/hooks/`:
+
+```typescript
+// hooks/queries/useFlyersQuery.ts
+export function useFlyersQuery(options?: { storeId?: number }) {
+  return useQuery({
+    queryKey: ['flyers', options],
+    queryFn: () => flyerService.getFlyers(options),
+    staleTime: 5 * 60 * 1000,
+  });
+}
+
+// hooks/mutations/useFlyerUploadMutation.ts
+export function useFlyerUploadMutation() {
+  const queryClient = useQueryClient();
+
+  return useMutation({
+    mutationFn: flyerService.uploadFlyer,
+    onSuccess: () => {
+      queryClient.invalidateQueries({ queryKey: ['flyers'] });
+    },
+  });
+}
+```
+
+### Page Components
+
+Pages are thin wrappers that compose feature components:
+
+```typescript
+// pages/Flyers.tsx
+import { FlyerGrid, FlyerUploader } from '@/features/flyer';
+import { PageLayout } from '@/components/layout';
+
+export function FliversPage() {
+  return (
+    <PageLayout title="My Flyers">
+      <FlyerUploader />
+      <FlyerGrid />
+    </PageLayout>
+  );
+}
+```
+
+### Cross-Feature Communication
+
+When features need to communicate, use:
+
+1. **Shared State Providers**: For global state (user, theme).
+2. **Query Invalidation**: For data synchronization.
+3. **Event Bus**: For loose coupling (see ADR-036).
+
+```typescript
+// Feature A triggers update
+const uploadMutation = useFlyerUploadMutation();
+await uploadMutation.mutateAsync(file);
+// Query invalidation automatically updates Feature B's flyer list
+```
+
+## Naming Conventions
+
+| Item           | Convention           | Example              |
+| -------------- | -------------------- | -------------------- |
+| Feature folder | kebab-case           | `voice-assistant/`   |
+| Component file | PascalCase           | `FlyerCard.tsx`      |
+| Hook file      | camelCase with `use` | `useFlyerDetails.ts` |
+| Type file      | lowercase            | `types.ts`           |
+| Utility file   | lowercase            | `utils.ts`           |
+| Index file     | lowercase            | `index.ts`           |
+
+## When to Create a New Feature
+
+Create a new feature folder when:
+
+1. The functionality is distinct and self-contained.
+2. It has its own set of components, hooks, and potentially types.
+3. It could theoretically be extracted into a separate package.
+4. It has minimal dependencies on other features.
+
+Do NOT create a feature folder for:
+
+- A single reusable component (use `components/`).
+- A single utility function (use `utils/`).
+- A single hook (use `hooks/`).
+
+## Consequences
+
+### Positive
+
+- **Discoverability**: Easy to find all code related to a feature.
+- **Encapsulation**: Features have clear boundaries and public APIs.
+- **Refactoring**: Can modify or remove features with confidence.
+- **Scalability**: Supports team growth with feature ownership.
+- **Testing**: Can test features in isolation.
+
+### Negative
+
+- **Duplication Risk**: Similar utilities might be duplicated across features.
+- **Decision Overhead**: Must decide when to extract to shared folders.
+- **Import Verbosity**: Feature imports can be longer.
+
+### Mitigation
+
+- Regular refactoring sessions to extract shared code.
+- Lint rules to prevent importing from feature internals.
+- Code review focus on proper feature boundaries.
+
+## Key Directories
+
+- `src/features/flyer/` - Flyer viewing and management
+- `src/features/shopping/` - Shopping list functionality
+- `src/features/charts/` - Budget and analytics charts
+- `src/features/voice-assistant/` - Voice command interface
+- `src/features/admin/` - Admin dashboard
+- `src/components/ui/` - Shared primitive components
+- `src/hooks/queries/` - TanStack Query hooks
+- `src/providers/` - React context providers

+# ADR-045: Test Data Factories and Fixtures
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-09
+
+## Context
+
+The application has a complex domain model with many entity types:
+
+- Users, Profiles, Addresses
+- Flyers, FlyerItems, Stores
+- ShoppingLists, ShoppingListItems
+- Recipes, RecipeIngredients
+- Gamification (points, badges, leaderboards)
+- And more...
+
+Testing requires realistic mock data that:
+
+1. Satisfies TypeScript types.
+2. Has valid relationships between entities.
+3. Is customizable for specific test scenarios.
+4. Is consistent across test suites.
+5. Avoids boilerplate in test files.
+
+## Decision
+
+We will implement a **factory function pattern** for test data generation:
+
+1. **Centralized Mock Factories**: All factories in a single, organized file.
+2. **Sensible Defaults**: Each factory produces valid data with minimal input.
+3. **Override Support**: Factories accept partial overrides for customization.
+4. **Relationship Helpers**: Factories can generate related entities.
+5. **Type Safety**: Factories return properly typed objects.
+
+### Design Principles
+
+- **Convention over Configuration**: Factories work with zero arguments.
+- **Composability**: Factories can call other factories.
+- **Immutability**: Each call returns a new object (no shared references).
+- **Predictability**: Deterministic output when seeded.
+
+## Implementation Details
+
+### Factory File Structure
+
+Located in `src/test/mockFactories.ts`:
+
+```typescript
+import { v4 as uuidv4 } from 'uuid';
+import type {
+  User,
+  UserProfile,
+  Flyer,
+  FlyerItem,
+  ShoppingList,
+  // ... other types
+} from '../types';
+
+// ============================================
+// PRIMITIVE HELPERS
+// ============================================
+let idCounter = 1;
+export const nextId = () => idCounter++;
+export const resetIdCounter = () => {
+  idCounter = 1;
+};
+
+export const randomEmail = () => `user-${uuidv4().slice(0, 8)}@test.com`;
+export const randomDate = (daysAgo = 0) => {
+  const date = new Date();
+  date.setDate(date.getDate() - daysAgo);
+  return date.toISOString();
+};
+
+// ============================================
+// USER FACTORIES
+// ============================================
+export const createMockUser = (overrides: Partial<User> = {}): User => ({
+  user_id: nextId(),
+  email: randomEmail(),
+  name: 'Test User',
+  role: 'user',
+  created_at: randomDate(30),
+  updated_at: randomDate(),

+});
+
+export const createMockUserProfile = (overrides: Partial<UserProfile> = {}): UserProfile => {
+  const user = createMockUser(overrides.user);
+  return {
+    user,
+    profile: createMockProfile({ user_id: user.user_id, ...overrides.profile }),
+    address: overrides.address ?? null,
+    preferences: overrides.preferences ?? null,
+  };
+};
+
+// ============================================
+// FLYER FACTORIES
+// ============================================
+export const createMockFlyer = (overrides: Partial<Flyer> = {}): Flyer => ({
+  flyer_id: nextId(),
+  file_name: 'test-flyer.jpg',
+  image_url: 'https://example.com/flyer.jpg',
+  icon_url: 'https://example.com/flyer-icon.jpg',
+  checksum: uuidv4(),
+  store_name: 'Test Store',
+  store_address: '123 Test St',
+  valid_from: randomDate(7),
+  valid_to: randomDate(-7), // 7 days in future
+  item_count: 10,
+  status: 'approved',
+  uploaded_by: null,
+  created_at: randomDate(7),
+  updated_at: randomDate(),
+  ...overrides,
+});
+
+export const createMockFlyerItem = (overrides: Partial<FlyerItem> = {}): FlyerItem => ({
+  flyer_item_id: nextId(),
+  flyer_id: overrides.flyer_id ?? nextId(),
+  item: 'Test Product',
+  price_display: '$2.99',
+  price_in_cents: 299,
+  quantity: 'each',
+  category_name: 'Groceries',
+  master_item_id: null,
+  view_count: 0,
+  click_count: 0,
+  created_at: randomDate(7),
+  updated_at: randomDate(),
+  ...overrides,
+});
+
+// ============================================
+// FLYER WITH ITEMS (COMPOSITE)
+// ============================================
+export const createMockFlyerWithItems = (
+  flyerOverrides: Partial<Flyer> = {},
+  itemCount = 5,
+): { flyer: Flyer; items: FlyerItem[] } => {
+  const flyer = createMockFlyer(flyerOverrides);
+  const items = Array.from({ length: itemCount }, (_, i) =>
+    createMockFlyerItem({
+      flyer_id: flyer.flyer_id,
+      item: `Product ${i + 1}`,
+      price_in_cents: 100 + i * 50,
+    }),
+  );
+  flyer.item_count = items.length;
+  return { flyer, items };
+};
+
+// ============================================
+// SHOPPING LIST FACTORIES
+// ============================================
+export const createMockShoppingList = (overrides: Partial<ShoppingList> = {}): ShoppingList => ({
+  shopping_list_id: nextId(),
+  user_id: overrides.user_id ?? nextId(),
+  name: 'Weekly Groceries',
+  is_active: true,
+  created_at: randomDate(14),
+  updated_at: randomDate(),
+  ...overrides,
+});
+
+export const createMockShoppingListItem = (
+  overrides: Partial<ShoppingListItem> = {},
+): ShoppingListItem => ({
+  shopping_list_item_id: nextId(),
+  shopping_list_id: overrides.shopping_list_id ?? nextId(),
+  item_name: 'Milk',
+  quantity: 1,
+  is_purchased: false,
+  created_at: randomDate(7),
+  updated_at: randomDate(),
+  ...overrides,
+});
+```
+
+### Usage in Tests
+
+```typescript
+import {
+  createMockUser,
+  createMockFlyer,
+  createMockFlyerWithItems,
+  resetIdCounter,
+} from '../test/mockFactories';
+
+describe('FlyerService', () => {
+  beforeEach(() => {
+    resetIdCounter(); // Consistent IDs across tests
+  });
+
+  it('should get flyer by ID', async () => {
+    const mockFlyer = createMockFlyer({ store_name: 'Walmart' });
+
+    mockDb.query.mockResolvedValue({ rows: [mockFlyer] });
+
+    const result = await flyerService.getFlyerById(mockFlyer.flyer_id);
+
+    expect(result.store_name).toBe('Walmart');
+  });
+
+  it('should return flyer with items', async () => {
+    const { flyer, items } = createMockFlyerWithItems(
+      { store_name: 'Costco' },
+      10, // 10 items
+    );
+
+    mockDb.query.mockResolvedValueOnce({ rows: [flyer] }).mockResolvedValueOnce({ rows: items });
+
+    const result = await flyerService.getFlyerWithItems(flyer.flyer_id);
+
+    expect(result.flyer.store_name).toBe('Costco');
+    expect(result.items).toHaveLength(10);
+  });
+});
+```
+
+### Bulk Data Generation
+
+For integration tests or seeding:
+
+```typescript
+export const createMockDataset = () => {
+  const users = Array.from({ length: 10 }, () => createMockUser());
+  const flyers = Array.from({ length: 5 }, () => createMockFlyer());
+  const flyersWithItems = flyers.map((flyer) => ({
+    flyer,
+    items: Array.from({ length: Math.floor(Math.random() * 20) + 5 }, () =>
+      createMockFlyerItem({ flyer_id: flyer.flyer_id }),
+    ),
+  }));
+
+  return { users, flyers, flyersWithItems };
+};
+```
+
+### API Response Factories
+
+For testing API handlers:
+
+```typescript
+export const createMockApiResponse = <T>(
+  data: T,
+  overrides: Partial<ApiResponse<T>> = {},
+): ApiResponse<T> => ({
+  success: true,
+  data,
+  meta: {
+    timestamp: new Date().toISOString(),
+    requestId: uuidv4(),
+    ...overrides.meta,
+  },
+  ...overrides,
+});
+
+export const createMockPaginatedResponse = <T>(
+  items: T[],
+  page = 1,
+  pageSize = 20,
+): PaginatedApiResponse<T> => ({
+  success: true,
+  data: items,
+  meta: {
+    timestamp: new Date().toISOString(),
+    requestId: uuidv4(),
+  },
+  pagination: {
+    page,
+    pageSize,
+    totalItems: items.length,
+    totalPages: Math.ceil(items.length / pageSize),
+    hasMore: false,
+  },
+});
+```
+
+### Database Query Mock Helpers
+
+```typescript
+export const mockQueryResult = <T>(rows: T[]) => ({
+  rows,
+  rowCount: rows.length,
+});
+
+export const mockEmptyResult = () => ({
+  rows: [],
+  rowCount: 0,
+});
+
+export const mockInsertResult = <T>(inserted: T) => ({
+  rows: [inserted],
+  rowCount: 1,
+});
+```
+
+## Test Cleanup Utilities
+
+```typescript
+// For integration tests with real database
+export const cleanupTestData = async (pool: Pool) => {
+  await pool.query('DELETE FROM flyer_items WHERE flyer_id > 1000000');
+  await pool.query('DELETE FROM flyers WHERE flyer_id > 1000000');
+  await pool.query('DELETE FROM users WHERE user_id > 1000000');
+};
+
+// Mark test data with high IDs
+export const createTestFlyer = (overrides: Partial<Flyer> = {}) =>
+  createMockFlyer({ flyer_id: 1000000 + nextId(), ...overrides });
+```
+
+## Consequences
+
+### Positive
+
+- **Consistency**: All tests use the same factory patterns.
+- **Type Safety**: Factories return correctly typed objects.
+- **Reduced Boilerplate**: Tests focus on behavior, not data setup.
+- **Maintainability**: Update factory once, all tests benefit.
+- **Flexibility**: Easy to create edge case data.
+
+### Negative
+
+- **Single Large File**: Factory file can become large.
+- **Learning Curve**: New developers must learn factory patterns.
+- **Maintenance**: Factories must be updated when types change.
+
+### Mitigation
+
+- Split factories into multiple files if needed (by domain).
+- Add JSDoc comments explaining each factory.
+- Use TypeScript to catch type mismatches automatically.
+

+- `src/test/mockFactories.ts` - All mock factory functions
+- `src/test/testUtils.ts` - Test helper utilities
+- `src/test/setup.ts` - Global test setup with factory reset

+# ADR-046: Image Processing Pipeline
+
+**Date**: 2026-01-09
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-09
+
+## Context
+
+The application handles significant image processing for flyer uploads:
+
+1. **Privacy Protection**: Strip EXIF metadata (location, device info).
+2. **Optimization**: Resize, compress, and convert images for web delivery.
+3. **Icon Generation**: Create thumbnails for listing views.
+4. **Format Support**: Handle JPEG, PNG, WebP, and PDF inputs.
+5. **Storage Management**: Organize processed images on disk.
+
+These operations must be:
+
+- **Performant**: Large images should not block the request.
+- **Secure**: Prevent malicious file uploads.
+- **Consistent**: Produce predictable output quality.
+- **Testable**: Support unit testing without real files.
+
+## Decision
+
+We will implement a modular image processing pipeline using:
+
+1. **Sharp**: For image resizing, compression, and format conversion.
+2. **EXIF Parsing**: For metadata extraction and stripping.
+3. **UUID Naming**: For unique, non-guessable file names.
+4. **Directory Structure**: Organized storage for originals and derivatives.
+
+### Design Principles
+
+- **Pipeline Pattern**: Chain processing steps in a predictable order.
+- **Fail-Fast Validation**: Reject invalid files before processing.
+- **Idempotent Operations**: Same input produces same output.
+- **Resource Cleanup**: Delete temp files on error.
+
+## Implementation Details
+
+### Image Processor Module
+
+Located in `src/utils/imageProcessor.ts`:
+
+```typescript
+import sharp from 'sharp';
+import path from 'path';
+import { v4 as uuidv4 } from 'uuid';
+import fs from 'fs/promises';
+import type { Logger } from 'pino';
+
+// ============================================
+// CONFIGURATION
+// ============================================
+const IMAGE_CONFIG = {
+  maxWidth: 2048,
+  maxHeight: 2048,
+  quality: 85,
+  iconSize: 200,
+  allowedFormats: ['jpeg', 'png', 'webp', 'avif'],
+  outputFormat: 'webp' as const,
+};
+
+// ============================================
+// MAIN PROCESSING FUNCTION
+// ============================================
+export async function processAndSaveImage(
+  inputPath: string,
+  outputDir: string,
+  originalFileName: string,
+  logger: Logger,
+): Promise<string> {
+  const outputFileName = `${uuidv4()}.${IMAGE_CONFIG.outputFormat}`;
+  const outputPath = path.join(outputDir, outputFileName);
+
+  logger.info({ inputPath, outputPath }, 'Processing image');
+
+  try {
+    // Create sharp instance and strip metadata
+    await sharp(inputPath)
+      .rotate() // Auto-rotate based on EXIF orientation
+      .resize(IMAGE_CONFIG.maxWidth, IMAGE_CONFIG.maxHeight, {
+        fit: 'inside',
+        withoutEnlargement: true,
+      })
+      .webp({ quality: IMAGE_CONFIG.quality })
+      .toFile(outputPath);
+
+    logger.info({ outputPath }, 'Image processed successfully');
+    return outputFileName;
+  } catch (error) {
+    logger.error({ error, inputPath }, 'Image processing failed');
+    throw error;
+  }
+}
+```
+
+### Icon Generation
+
+```typescript
+export async function generateFlyerIcon(
+  inputPath: string,
+  iconsDir: string,
+  logger: Logger,
+): Promise<string> {
+  // Ensure icons directory exists
+  await fs.mkdir(iconsDir, { recursive: true });
+
+  const iconFileName = `${uuidv4()}-icon.webp`;
+  const iconPath = path.join(iconsDir, iconFileName);
+
+  logger.info({ inputPath, iconPath }, 'Generating icon');
+
+  await sharp(inputPath)
+    .resize(IMAGE_CONFIG.iconSize, IMAGE_CONFIG.iconSize, {
+      fit: 'cover',
+      position: 'top', // Flyers usually have store name at top
+    })
+    .webp({ quality: 80 })
+    .toFile(iconPath);
+
+  logger.info({ iconPath }, 'Icon generated successfully');
+  return iconFileName;
+}
+```
+
+### EXIF Metadata Extraction
+
+For audit/logging purposes before stripping:
+
+```typescript
+import ExifParser from 'exif-parser';
+
+export async function extractExifMetadata(
+  filePath: string,
+  logger: Logger,
+): Promise<ExifMetadata | null> {
+  try {
+    const buffer = await fs.readFile(filePath);
+    const parser = ExifParser.create(buffer);
+    const result = parser.parse();
+
+    const metadata: ExifMetadata = {
+      make: result.tags?.Make,
+      model: result.tags?.Model,
+      dateTime: result.tags?.DateTimeOriginal,
+      gpsLatitude: result.tags?.GPSLatitude,
+      gpsLongitude: result.tags?.GPSLongitude,
+      orientation: result.tags?.Orientation,
+    };
+
+    // Log if GPS data was present (privacy concern)
+    if (metadata.gpsLatitude || metadata.gpsLongitude) {
+      logger.info({ filePath }, 'GPS data found in image, will be stripped during processing');
+    }
+
+    return metadata;
+  } catch (error) {
+    logger.debug({ error, filePath }, 'No EXIF data found or parsing failed');
+    return null;
+  }
+}
+```
+
+### PDF to Image Conversion
+
+```typescript
+import * as pdfjs from 'pdfjs-dist';
+
+export async function convertPdfToImages(
+  pdfPath: string,
+  outputDir: string,
+  logger: Logger,
+): Promise<string[]> {
+  const pdfData = await fs.readFile(pdfPath);
+  const pdf = await pdfjs.getDocument({ data: pdfData }).promise;
+
+  const outputPaths: string[] = [];
+
+  for (let i = 1; i <= pdf.numPages; i++) {
+    const page = await pdf.getPage(i);
+    const viewport = page.getViewport({ scale: 2.0 }); // 2x for quality
+
+    // Create canvas and render
+    const canvas = createCanvas(viewport.width, viewport.height);
+    const context = canvas.getContext('2d');
+
+    await page.render({
+      canvasContext: context,
+      viewport: viewport,
+    }).promise;
+
+    // Save as image
+    const outputFileName = `${uuidv4()}-page-${i}.png`;
+    const outputPath = path.join(outputDir, outputFileName);
+    const buffer = canvas.toBuffer('image/png');
+    await fs.writeFile(outputPath, buffer);
+
+    outputPaths.push(outputPath);
+    logger.info({ page: i, outputPath }, 'PDF page converted to image');
+  }
+
+  return outputPaths;
+}
+```
+
+### File Validation
+
+```typescript
+import { fileTypeFromBuffer } from 'file-type';
+
+export async function validateImageFile(
+  filePath: string,
+  logger: Logger,
+): Promise<{ valid: boolean; mimeType: string | null; error?: string }> {
+  try {
+    const buffer = await fs.readFile(filePath, { length: 4100 }); // Read header only
+    const type = await fileTypeFromBuffer(buffer);
+
+    if (!type) {
+      return { valid: false, mimeType: null, error: 'Unknown file type' };
+    }
+
+    const allowedMimes = ['image/jpeg', 'image/png', 'image/webp', 'image/avif', 'application/pdf'];
+
+    if (!allowedMimes.includes(type.mime)) {
+      return {
+        valid: false,
+        mimeType: type.mime,
+        error: `File type ${type.mime} not allowed`,
+      };
+    }
+
+    return { valid: true, mimeType: type.mime };
+  } catch (error) {
+    logger.error({ error, filePath }, 'File validation failed');
+    return { valid: false, mimeType: null, error: 'Validation error' };
+  }
+}
+```
+
+### Storage Organization
+
+```
+flyer-images/
+├── originals/           # Uploaded files (if kept)
+│   └── {uuid}.{ext}
+├── processed/           # Optimized images (or root level)
+│   └── {uuid}.webp
+├── icons/               # Thumbnails
+│   └── {uuid}-icon.webp
+└── temp/                # Temporary processing files
+    └── {uuid}.tmp
+```
+
+### Cleanup Utilities
+
+```typescript
+export async function cleanupTempFiles(
+  tempDir: string,
+  maxAgeMs: number,
+  logger: Logger,
+): Promise<number> {
+  const files = await fs.readdir(tempDir);
+  const now = Date.now();
+  let deletedCount = 0;
+
+  for (const file of files) {
+    const filePath = path.join(tempDir, file);
+    const stats = await fs.stat(filePath);
+    const age = now - stats.mtimeMs;
+
+    if (age > maxAgeMs) {
+      await fs.unlink(filePath);
+      deletedCount++;
+    }
+  }
+
+  logger.info({ deletedCount, tempDir }, 'Cleaned up temp files');
+  return deletedCount;
+}
+```
+
+### Integration with Flyer Processing
+
+```typescript
+// In flyerProcessingService.ts
+export async function processUploadedFlyer(
+  file: Express.Multer.File,
+  logger: Logger,
+): Promise<{ imageUrl: string; iconUrl: string }> {
+  const flyerImageDir = 'flyer-images';
+  const iconsDir = path.join(flyerImageDir, 'icons');
+
+  // 1. Validate file
+  const validation = await validateImageFile(file.path, logger);
+  if (!validation.valid) {
+    throw new ValidationError([{ path: 'file', message: validation.error! }]);
+  }
+
+  // 2. Extract and log EXIF before stripping
+  await extractExifMetadata(file.path, logger);
+
+  // 3. Process and optimize image
+  const processedFileName = await processAndSaveImage(
+    file.path,
+    flyerImageDir,
+    file.originalname,
+    logger,
+  );
+
+  // 4. Generate icon
+  const processedImagePath = path.join(flyerImageDir, processedFileName);
+  const iconFileName = await generateFlyerIcon(processedImagePath, iconsDir, logger);
+
+  // 5. Construct URLs
+  const baseUrl = process.env.BACKEND_URL || 'http://localhost:3001';
+  const imageUrl = `${baseUrl}/flyer-images/${processedFileName}`;
+  const iconUrl = `${baseUrl}/flyer-images/icons/${iconFileName}`;
+
+  // 6. Delete original upload (privacy)
+  await fs.unlink(file.path);
+
+  return { imageUrl, iconUrl };
+}
+```
+
+## Consequences
+
+### Positive
+
+- **Privacy**: EXIF metadata (including GPS) is stripped automatically.
+- **Performance**: WebP output reduces file sizes by 25-35%.
+- **Consistency**: All images processed to standard format and dimensions.
+- **Security**: File type validation prevents malicious uploads.
+- **Organization**: Clear directory structure for storage management.
+
+### Negative
+
+- **CPU Intensive**: Image processing can be slow for large files.
+- **Storage**: Keeping originals doubles storage requirements.
+- **Dependency**: Sharp requires native binaries.
+
+### Mitigation
+
+- Process images in background jobs (BullMQ queue).
+- Configure whether to keep originals based on requirements.
+- Use pre-built Sharp binaries via npm.
+
+## Key Files
+
+- `src/utils/imageProcessor.ts` - Core image processing functions
+- `src/services/flyer/flyerProcessingService.ts` - Integration with flyer workflow

+# ADR-047: Project File and Folder Organization
+
+**Date**: 2026-01-09
+
+**Status**: Proposed
+
+**Effort**: XL (Major reorganization across entire codebase)
+
+## Context
+
+The project has grown organically with a mix of organizational patterns:
+
+- **By Type**: Components, hooks, middleware, utilities, types all in flat directories
+- **By Feature**: Routes, database modules, and partial feature directories
+- **Mixed Concerns**: Frontend and backend code intermingled in `src/`
+
+Current pain points:
+
+1. **Flat services directory**: 75+ files with no subdirectory grouping
+2. **Monolithic types.ts**: 750+ lines, unclear when to add new types
+3. **Flat components directory**: 43+ components at root level
+4. **Incomplete feature modules**: Features contain only UI, not domain logic
+5. **No clear frontend/backend separation**: Both share `src/` root
+
+As the project scales, these issues compound, making navigation, refactoring, and onboarding increasingly difficult.
+
+## Decision
+
+We will adopt a **domain-driven organization** with clear separation between:
+
+1. **Client code** (React, browser-only)
+2. **Server code** (Express, Node-only)
+3. **Shared code** (Types, utilities used by both)
+
+Within each layer, organize by **feature/domain** rather than by file type.
+
+### Design Principles
+
+- **Colocation**: Related code lives together (components, hooks, types, tests)
+- **Explicit Boundaries**: Clear separation between client, server, and shared
+- **Feature Ownership**: Each domain owns its entire vertical slice
+- **Discoverability**: New developers can find code by thinking about features, not file types
+- **Incremental Migration**: Structure supports gradual transition from current layout

+
+## Domain Module Structure
+
+Each server domain follows a consistent structure:
+
+```
+domains/flyer/
+├── flyer.service.ts        # Business logic
+├── flyer.routes.ts         # Express routes
+├── flyer.controller.ts     # Route handlers
+├── flyer.repository.ts     # Database access
+├── flyer.types.ts          # Domain-specific types
+├── flyer.service.test.ts   # Service tests
+├── flyer.routes.test.ts    # Route tests
+└── index.ts                # Public API
+```
+
+### Domain Index Pattern
+
+Each domain exports a clean public API:
+
+```typescript
+// server/domains/flyer/index.ts
+export { FlyerService } from './flyer.service';
+export { flyerRoutes } from './flyer.routes';
+export type { FlyerWithItems, FlyerCreateInput } from './flyer.types';
+```
+
+## Client Feature Module Structure
+
+Each client feature follows a consistent structure:
+
+```
+client/features/flyer/
+├── components/
+│   ├── FlyerCard.tsx
+│   ├── FlyerCard.test.tsx
+│   ├── FlyerGrid.tsx
+│   └── index.ts
+├── hooks/
+│   ├── useFlyersQuery.ts
+│   ├── useFlyerUploadMutation.ts
+│   └── index.ts
+├── types.ts                # Feature-specific client types
+└── index.ts                # Public API
+```
+
+## Import Path Aliases
+
+Configure TypeScript and bundler for clean imports:
+
+```typescript
+// tsconfig.json paths
+{
+  "paths": {
+    "@/client/*": ["src/client/*"],
+    "@/server/*": ["src/server/*"],
+    "@/shared/*": ["src/shared/*"],
+    "@/tests/*": ["src/tests/*"]
+  }
+}
+
+// Usage examples
+import { Button, Card } from '@/client/components/ui';
+import { useFlyersQuery } from '@/client/features/flyer';
+import { FlyerService } from '@/server/domains/flyer';
+import type { Flyer } from '@/shared/types/entities';
+```
+
+## Migration Strategy
+
+Given the scope of this reorganization, migrate incrementally:
+
+### Phase 1: Create Directory Structure
+
+1. Create `client/`, `server/`, `shared/` directories
+2. Set up path aliases in tsconfig.json
+3. Update build configuration (Vite)
+
+### Phase 2: Migrate Shared Code
+
+1. Move types to `shared/types/`
+2. Move schemas to `shared/schemas/`
+3. Move shared utils to `shared/utils/`
+4. Update imports across codebase
+
+### Phase 3: Migrate Server Code
+
+1. Create `server/domains/` structure
+2. Move one domain at a time (start with `auth` or `user`)
+3. Move each service + routes + repository together
+4. Update route registration in app.ts
+5. Run tests after each domain migration
+
+### Phase 4: Migrate Client Code
+
+1. Create `client/features/` structure
+2. Move components into features
+3. Move hooks into features or shared hooks
+4. Move pages to `client/pages/`
+5. Organize shared components into categories
+
+### Phase 5: Cleanup
+
+1. Remove empty old directories
+2. Update all remaining imports
+3. Update CI/CD paths if needed
+4. Update documentation
+

+## Consequences
+
+### Positive
+
+- **Clear Boundaries**: Frontend, backend, and shared code are explicitly separated
+- **Feature Discoverability**: Find all code for a feature in one place
+- **Parallel Development**: Teams can work on domains independently
+- **Easier Refactoring**: Domain boundaries make changes localized
+- **Better Onboarding**: New developers navigate by feature, not file type
+- **Scalability**: Structure supports growth without becoming unwieldy
+
+### Negative
+
+- **Large Migration Effort**: Significant one-time cost (XL effort)
+- **Import Updates**: All imports need updating
+- **Learning Curve**: Team must learn new structure
+- **Merge Conflicts**: In-flight PRs will need rebasing
+
+### Mitigation
+
+- Use automated tools (e.g., `ts-morph`) to update imports
+- Migrate one domain/feature at a time
+- Create a migration checklist and track progress
+- Coordinate with team to minimize in-flight work during migration phases
+- Consider using feature flags to ship incrementally

+| ---------------- | -------------------------- | ----------------------------------------- |
+| Frontend/Backend | Mixed in `src/`            | Separated in `client/` and `server/`      |
+| Services         | Flat directory (75+ files) | Grouped by domain                         |
+| Components       | Flat directory (43+ files) | Categorized (ui, layout, feedback, forms) |
+| Types            | Monolithic `types.ts`      | Split by entity in `shared/types/`        |
+| Features         | UI-only                    | Full vertical slice (UI + hooks + types)  |
+| Routes           | Separate from services     | Co-located in domain                      |

+# ADR-048: Authentication Strategy
+
+**Date**: 2026-01-09
+
+**Status**: Partially Implemented
+
+**Implemented**: 2026-01-09 (Local auth only)
+
+## Context
+
+The application requires a secure authentication system that supports both traditional email/password login and social OAuth providers (Google, GitHub). The system must handle user sessions, token refresh, account security (lockout after failed attempts), and integrate seamlessly with the existing Express middleware pipeline.
+
+Currently, **only local authentication is enabled**. OAuth strategies are fully implemented but commented out, pending configuration of OAuth provider credentials.
+
+## Decision
+
+We will implement a stateless JWT-based authentication system with the following components:
+
+1. **Local Authentication**: Email/password login with bcrypt hashing.
+2. **OAuth Authentication**: Google and GitHub OAuth 2.0 (currently disabled).
+3. **JWT Access Tokens**: Short-lived tokens (15 minutes) for API authentication.
+4. **Refresh Tokens**: Long-lived tokens (7 days) stored in HTTP-only cookies.
+5. **Account Security**: Lockout after 5 failed login attempts for 15 minutes.
+
+### Design Principles
+
+- **Stateless Sessions**: No server-side session storage; JWT contains all auth state.
+- **Defense in Depth**: Multiple security layers (rate limiting, lockout, secure cookies).
+- **Graceful OAuth Degradation**: OAuth is optional; system works with local auth only.
+- **OAuth User Flexibility**: OAuth users have `password_hash = NULL` in database.
+
+## Current Implementation Status
+
+| Component                | Status  | Notes                                                       |
+| ------------------------ | ------- | ----------------------------------------------------------- |
+| **Local Authentication** | Enabled | Email/password with bcrypt (salt rounds = 10)               |
+| **JWT Access Tokens**    | Enabled | 15-minute expiry, `Authorization: Bearer` header            |
+| **Refresh Tokens**       | Enabled | 7-day expiry, HTTP-only cookie                              |
+| **Account Lockout**      | Enabled | 5 failed attempts, 15-minute lockout                        |
+| **Password Reset**       | Enabled | Email-based token flow                                      |
+| **Google OAuth**         | Enabled | Requires GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET env vars |
+| **GitHub OAuth**         | Enabled | Requires GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET env vars |
+| **OAuth Routes**         | Enabled | `/api/auth/google`, `/api/auth/github` + callbacks          |
+| **OAuth Frontend UI**    | Enabled | Login buttons in AuthView.tsx                               |

+
+### OAuth Strategies (Disabled)
+
+#### Google OAuth
+
+Located in `src/routes/passport.routes.ts` (lines 167-217, commented):
+
+```typescript
+// passport.use(new GoogleStrategy({
+//     clientID: process.env.GOOGLE_CLIENT_ID!,
+//     clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
+//     callbackURL: '/api/auth/google/callback',
+//     scope: ['profile', 'email']
+//   },
+//   async (accessToken, refreshToken, profile, done) => {
+//     const email = profile.emails?.[0]?.value;
+//     const user = await db.findUserByEmail(email);
+//     if (user) {
+//       return done(null, user);
+//     }
+//     // Create new user with null password_hash
+//     const newUser = await db.createUser(email, null, {
+//       full_name: profile.displayName,
+//       avatar_url: profile.photos?.[0]?.value
+//     });
+//     return done(null, newUser);
+//   }
+// ));
+```
+
+#### GitHub OAuth
+
+Located in `src/routes/passport.routes.ts` (lines 219-269, commented):
+
+```typescript
+// passport.use(new GitHubStrategy({
+//     clientID: process.env.GITHUB_CLIENT_ID!,
+//     clientSecret: process.env.GITHUB_CLIENT_SECRET!,
+//     callbackURL: '/api/auth/github/callback',
+//     scope: ['user:email']
+//   },
+//   async (accessToken, refreshToken, profile, done) => {
+//     const email = profile.emails?.[0]?.value;
+//     // Similar flow to Google OAuth
+//   }
+// ));
+```
+
+#### OAuth Routes (Disabled)
+
+Located in `src/routes/auth.routes.ts` (lines 289-315, commented):
+
+```typescript
+// const handleOAuthCallback = (req, res) => {
+//     const user = req.user;
+//     const accessToken = jwt.sign(payload, JWT_SECRET, { expiresIn: '15m' });
+//     const refreshToken = crypto.randomBytes(64).toString('hex');
+//
+//     await db.saveRefreshToken(user.user_id, refreshToken);
+//     res.cookie('refreshToken', refreshToken, { httpOnly: true, secure: true });
+//     res.redirect(`${FRONTEND_URL}/auth/callback?token=${accessToken}`);
+// };
+
+// router.get('/google', passport.authenticate('google', { session: false }));
+// router.get('/google/callback', passport.authenticate('google', { ... }), handleOAuthCallback);
+// router.get('/github', passport.authenticate('github', { session: false }));
+// router.get('/github/callback', passport.authenticate('github', { ... }), handleOAuthCallback);
+```
+
+### Database Schema
+
+**Users Table** (`sql/initial_schema.sql`):
+
+```sql
+CREATE TABLE public.users (
+  user_id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
+  email TEXT NOT NULL UNIQUE,
+  password_hash TEXT,              -- NULL for OAuth-only users
+  refresh_token TEXT,              -- Current refresh token
+  failed_login_attempts INTEGER DEFAULT 0,
+  last_failed_login TIMESTAMPTZ,
+  created_at TIMESTAMPTZ DEFAULT now(),
+  updated_at TIMESTAMPTZ DEFAULT now()
+);
+```
+
+**Note**: There is no separate OAuth provider mapping table. OAuth users are identified by `password_hash = NULL`. If a user signs up via OAuth and later wants to add a password, this would require schema changes.
+
+### Authentication Middleware
+
+Located in `src/routes/passport.routes.ts`:
+
+```typescript
+// Require admin role
+export const isAdmin = (req, res, next) => {
+  if (req.user?.role === 'admin') {
+    next();
+  } else {
+    next(new ForbiddenError('Administrator access required.'));
+  }
+};
+
+// Optional auth - attach user if present, continue if not
+export const optionalAuth = (req, res, next) => {
+  passport.authenticate('jwt', { session: false }, (err, user) => {
+    if (user) req.user = user;
+    next();
+  })(req, res, next);
+};
+
+// Mock auth for testing (only in NODE_ENV=test)
+export const mockAuth = (req, res, next) => {
+  if (process.env.NODE_ENV === 'test') {
+    req.user = createMockUserProfile({ role: 'admin' });
+  }
+  next();
+};
+```
+
+## Enabling OAuth
+
+### Step 1: Set Environment Variables
+
+Add to `.env`:
+
+```bash
+# Google OAuth
+GOOGLE_CLIENT_ID=your-google-client-id
+GOOGLE_CLIENT_SECRET=your-google-client-secret
+
+# GitHub OAuth
+GITHUB_CLIENT_ID=your-github-client-id
+GITHUB_CLIENT_SECRET=your-github-client-secret
+```
+
+### Step 2: Configure OAuth Providers
+
+**Google Cloud Console**:
+
+1. Create project at <https://console.cloud.google.com/>
+2. Enable Google+ API
+3. Create OAuth 2.0 credentials (Web Application)
+4. Add authorized redirect URI:
+   - Development: `http://localhost:3001/api/auth/google/callback`
+   - Production: `https://your-domain.com/api/auth/google/callback`
+
+**GitHub Developer Settings**:
+
+1. Go to <https://github.com/settings/developers>
+2. Create new OAuth App
+3. Set Authorization callback URL:
+   - Development: `http://localhost:3001/api/auth/github/callback`
+   - Production: `https://your-domain.com/api/auth/github/callback`
+
+### Step 3: Uncomment Backend Code
+
+**In `src/routes/passport.routes.ts`**:
+
+1. Uncomment import statements (lines 5-6):
+
+   ```typescript
+   import { Strategy as GoogleStrategy } from 'passport-google-oauth20';
+   import { Strategy as GitHubStrategy } from 'passport-github2';
+   ```
+
+2. Uncomment Google strategy (lines 167-217)
+3. Uncomment GitHub strategy (lines 219-269)
+
+**In `src/routes/auth.routes.ts`**:
+
+1. Uncomment `handleOAuthCallback` function (lines 291-309)
+2. Uncomment OAuth routes (lines 311-315)
+
+### Step 4: Add Frontend OAuth Buttons
+
+Create login buttons that redirect to:
+
+- Google: `GET /api/auth/google`
+- GitHub: `GET /api/auth/github`
+
+Handle callback at `/auth/callback?token=<accessToken>`:
+
+1. Extract token from URL
+2. Store in client-side token storage
+3. Redirect to dashboard
+
+### Step 5: Handle OAuth Callback Page
+
+Create `src/pages/AuthCallback.tsx`:
+
+```typescript
+const AuthCallback = () => {
+  const token = new URLSearchParams(location.search).get('token');
+  if (token) {
+    setToken(token);
+    navigate('/dashboard');
+  } else {
+    navigate('/login?error=auth_failed');
+  }
+};
+```
+
+## Known Limitations
+
+1. **No OAuth Provider ID Mapping**: Users are identified by email only. If a user has accounts with different emails on Google and GitHub, they create separate accounts.
+
+2. **No Account Linking**: Users cannot link multiple OAuth providers to one account.
+
+3. **No Password Addition for OAuth Users**: OAuth-only users cannot add a password to enable local login.
+
+4. **No PKCE Flow**: OAuth implementation uses standard flow, not PKCE (Proof Key for Code Exchange).
+
+5. **No OAuth State Parameter Validation**: The commented code doesn't show explicit state parameter handling for CSRF protection (Passport may handle this internally).
+
+6. **No Refresh Token from OAuth Providers**: Only email/profile data is extracted; OAuth refresh tokens are not stored for API access.
+
+## Dependencies
+
+**Installed** (all available):
+
+- `passport` v0.7.0
+- `passport-local` v1.0.0
+- `passport-jwt` v4.0.1
+- `passport-google-oauth20` v2.0.0
+- `passport-github2` v0.1.12
+- `bcrypt` v5.x
+- `jsonwebtoken` v9.x
+
+**Type Definitions**:
+
+- `@types/passport`
+- `@types/passport-local`
+- `@types/passport-jwt`
+- `@types/passport-google-oauth20`
+- `@types/passport-github2`
+
+## Consequences
+
+### Positive
+
+- **Stateless Architecture**: No session storage required; scales horizontally.
+- **Secure by Default**: HTTP-only cookies, short token expiry, bcrypt hashing.
+- **Account Protection**: Lockout prevents brute-force attacks.
+- **Flexible OAuth**: Can enable/disable OAuth without code changes (just env vars + uncommenting).
+- **Graceful Degradation**: System works with local auth only.
+
+### Negative
+
+- **OAuth Disabled by Default**: Requires manual uncommenting to enable.
+- **No Account Linking**: Multiple OAuth providers create separate accounts.
+- **Frontend Work Required**: OAuth login buttons don't exist yet.
+- **Token in URL**: OAuth callback passes token in URL (visible in browser history).
+
+### Mitigation
+
+- Document OAuth enablement steps clearly (see [../architecture/AUTHENTICATION.md](../architecture/AUTHENTICATION.md)).
+- Consider adding OAuth provider ID columns for future account linking.
+- Use URL fragment (`#token=`) instead of query parameter for callback.

+# ADR-049: Gamification and Achievement System
+
+**Date**: 2026-01-11
+
+**Status**: Accepted
+
+**Implemented**: 2026-01-11
+
+## Context
+
+The application implements a gamification system to encourage user engagement through achievements and points. Users earn achievements for completing specific actions within the platform, and these achievements contribute to a points-based leaderboard.
+
+Key requirements:
+
+1. **User Engagement**: Reward users for meaningful actions (uploads, recipes, sharing).
+2. **Progress Tracking**: Show users their accomplishments and progress.
+3. **Social Competition**: Leaderboard to compare users by points.
+4. **Idempotent Awards**: Achievements should only be awarded once per user.
+5. **Transactional Safety**: Achievement awards must be atomic with the triggering action.
+
+## Decision
+
+We will implement a database-driven gamification system with:
+
+1. **Database Functions**: Core logic in PostgreSQL for atomicity and idempotency.
+2. **Database Triggers**: Automatic achievement awards on specific events.
+3. **Application-Level Awards**: Explicit calls from service layer when triggers aren't suitable.
+4. **Points Aggregation**: Stored in user profile for efficient leaderboard queries.
+
+### Design Principles
+
+- **Single Award**: Each achievement can only be earned once per user (enforced by unique constraint).
+- **Atomic Operations**: Achievement awards happen within the same transaction as the triggering action.
+- **Silent Failure**: If an achievement doesn't exist, the award function returns silently (no error).
+- **Points Sync**: Points are updated on the profile immediately when an achievement is awarded.
+
+## Implementation Details
+
+### Database Schema
+
+```sql
+-- Achievements master table
+CREATE TABLE public.achievements (
+  achievement_id BIGSERIAL PRIMARY KEY,
+  name TEXT UNIQUE NOT NULL,
+  description TEXT NOT NULL,
+  icon TEXT NOT NULL,
+  points_value INTEGER NOT NULL DEFAULT 0,
+  created_at TIMESTAMPTZ DEFAULT NOW()
+);
+
+-- User achievements (junction table)
+CREATE TABLE public.user_achievements (
+  user_id UUID REFERENCES public.users(user_id) ON DELETE CASCADE,
+  achievement_id BIGINT REFERENCES public.achievements(achievement_id) ON DELETE CASCADE,
+  achieved_at TIMESTAMPTZ DEFAULT NOW(),
+  PRIMARY KEY (user_id, achievement_id)
+);
+
+-- Points stored on profile for efficient leaderboard
+ALTER TABLE public.profiles ADD COLUMN points INTEGER DEFAULT 0;
+```
+
+### Award Achievement Function
+
+Located in `sql/Initial_triggers_and_functions.sql`:
+
+```sql
+CREATE OR REPLACE FUNCTION public.award_achievement(p_user_id UUID, p_achievement_name TEXT)
+RETURNS void
+LANGUAGE plpgsql
+SECURITY DEFINER
+AS $$
+DECLARE
+    v_achievement_id BIGINT;
+    v_points_value INTEGER;
+BEGIN
+    -- Find the achievement by name to get its ID and point value.
+    SELECT achievement_id, points_value INTO v_achievement_id, v_points_value
+    FROM public.achievements WHERE name = p_achievement_name;
+
+    -- If the achievement doesn't exist, do nothing.
+    IF v_achievement_id IS NULL THEN
+        RETURN;
+    END IF;
+
+    -- Insert the achievement for the user.
+    -- ON CONFLICT DO NOTHING ensures idempotency.
+    INSERT INTO public.user_achievements (user_id, achievement_id)
+    VALUES (p_user_id, v_achievement_id)
+    ON CONFLICT (user_id, achievement_id) DO NOTHING;
+
+    -- If the insert was successful (user didn't have it), update their points.
+    IF FOUND THEN
+        UPDATE public.profiles SET points = points + v_points_value WHERE user_id = p_user_id;
+    END IF;
+END;
+$$;
+```
+

+
+### Achievement Triggers
+
+#### User Registration (Database Trigger)
+
+Awards "Welcome Aboard" when a new user is created:
+
+```sql
+-- In handle_new_user() function
+PERFORM public.award_achievement(new.user_id, 'Welcome Aboard');
+```
+
+#### Flyer Upload (Database Trigger + Application Code)
+
+Awards "First-Upload" when a flyer is inserted with an `uploaded_by` value:
+
+```sql
+-- In log_new_flyer() trigger function
+IF NEW.uploaded_by IS NOT NULL THEN
+    PERFORM public.award_achievement(NEW.uploaded_by, 'First-Upload');
+END IF;
+```
+
+Additionally, the `FlyerPersistenceService.saveFlyer()` method explicitly awards the achievement within the transaction:
+
+```typescript
+// In src/services/flyerPersistenceService.server.ts
+if (userId) {
+  const gamificationRepo = new GamificationRepository(client);
+  await gamificationRepo.awardAchievement(userId, 'First-Upload', logger);
+}
+```
+
+### Repository Layer
+
+Located in `src/services/db/gamification.db.ts`:
+
+```typescript
+export class GamificationRepository {
+  private db: Pick<Pool | PoolClient, 'query'>;
+
+  constructor(db: Pick<Pool | PoolClient, 'query'> = getPool()) {
+    this.db = db;
+  }
+
+  async getUserAchievements(
+    userId: string,
+    logger: Logger,
+  ): Promise<(UserAchievement & Achievement)[]> {
+    const query = `
+      SELECT ua.user_id, ua.achievement_id, ua.achieved_at,
+             a.name, a.description, a.icon, a.points_value, a.created_at
+      FROM public.user_achievements ua
+      JOIN public.achievements a ON ua.achievement_id = a.achievement_id
+      WHERE ua.user_id = $1
+      ORDER BY ua.achieved_at DESC;
+    `;
+    const res = await this.db.query(query, [userId]);
+    return res.rows;
+  }
+
+  async awardAchievement(userId: string, achievementName: string, logger: Logger): Promise<void> {
+    await this.db.query('SELECT public.award_achievement($1, $2)', [userId, achievementName]);
+  }
+
+  async getLeaderboard(limit: number, logger: Logger): Promise<LeaderboardUser[]> {
+    const query = `
+      SELECT user_id, full_name, avatar_url, points,
+             RANK() OVER (ORDER BY points DESC) as rank
+      FROM public.profiles
+      ORDER BY points DESC, full_name ASC
+      LIMIT $1;
+    `;
+    const res = await this.db.query(query, [limit]);
+    return res.rows;
+  }
+}
+```
+
+### API Endpoints
+
+| Method | Endpoint                        | Description                     |
+| ------ | ------------------------------- | ------------------------------- |
+| GET    | `/api/achievements`             | List all available achievements |
+| GET    | `/api/achievements/me`          | Get current user's achievements |
+| GET    | `/api/achievements/leaderboard` | Get top users by points         |
+
+## Testing Considerations
+
+### Critical Testing Requirements
+
+When testing gamification features, be aware of the following:
+
+1. **Database Seed Data**: Achievement definitions must exist in the database before tests run. The `award_achievement()` function silently returns if the achievement name doesn't exist.
+
+2. **Transactional Context**: When awarding achievements from within a transaction:
+   - The achievement is visible within the transaction immediately
+   - External queries won't see the achievement until the transaction commits
+   - Tests should wait for job completion before asserting achievement state
+
+3. **Vitest Global Setup Context**: The integration test global setup runs in a separate Node.js context. Achievement verification must use direct database queries, not mocked services.
+
+4. **Achievement Idempotency**: Calling `award_achievement()` multiple times for the same user/achievement combination is safe and expected. Only the first call actually inserts.
+
+### Example Integration Test Pattern
+
+```typescript
+it('should award the "First Upload" achievement after flyer processing', async () => {
+  // 1. Create user (awards "Welcome Aboard" via database trigger)
+  const { user: testUser, token } = await createAndLoginUser({...});
+
+  // 2. Upload flyer (triggers async job)
+  const uploadResponse = await request
+    .post('/api/flyers/upload')
+    .set('Authorization', `Bearer ${token}`)
+    .attach('flyerFile', testImagePath);
+  expect(uploadResponse.status).toBe(202);
+
+  // 3. Wait for job to complete
+  await poll(async () => {
+    const status = await request.get(`/api/flyers/job/${jobId}/status`);
+    return status.body.data.status === 'completed';
+  }, { timeout: 15000 });
+
+  // 4. Wait for achievements to be visible (transaction committed)
+  await vi.waitUntil(async () => {
+    const achievements = await db.gamificationRepo.getUserAchievements(
+      testUser.user.user_id,
+      logger
+    );
+    return achievements.length >= 2; // Welcome Aboard + First-Upload
+  }, { timeout: 15000, interval: 500 });
+
+  // 5. Assert specific achievements
+  const userAchievements = await db.gamificationRepo.getUserAchievements(
+    testUser.user.user_id,
+    logger
+  );
+  expect(userAchievements.find(a => a.name === 'Welcome Aboard')).toBeDefined();
+  expect(userAchievements.find(a => a.name === 'First-Upload')).toBeDefined();
+});
+```
+
+### Common Test Pitfalls
+
+1. **Missing Seed Data**: If tests fail with "achievement not found", ensure the test database has the achievements table populated.
+
+2. **Race Conditions**: Achievement awards in async jobs may not be visible immediately. Always poll or use `vi.waitUntil()`.
+
+3. **Wrong User ID**: Verify the user ID passed to `awardAchievement()` matches the user created in the test.
+
+4. **Transaction Isolation**: When querying within a test, use the same database connection if checking mid-transaction state.
+
+## Consequences
+
+### Positive
+
+- **Engagement**: Users have clear goals and rewards for platform activity.
+- **Scalability**: Points stored on profile enable O(1) leaderboard sorting.
+- **Reliability**: Database-level idempotency prevents duplicate awards.
+- **Flexibility**: New achievements can be added via SQL without code changes.
+
+### Negative
+
+- **Complexity**: Multiple award paths (triggers + application code) require careful coordination.
+- **Testing**: Async nature of some awards complicates integration testing.
+- **Coupling**: Achievement names are strings; typos fail silently.
+
+### Mitigation
+
+- Use constants for achievement names in application code.
+- Document all award trigger points clearly.
+- Test each achievement path independently.

+# ADR-050: PostgreSQL Function Observability
+
+**Date**: 2026-01-11
+
+**Status**: Proposed
+
+**Related**: [ADR-015](0015-application-performance-monitoring-and-error-tracking.md), [ADR-004](0004-standardized-application-wide-structured-logging.md)
+
+## Context
+
+The application uses 30+ PostgreSQL functions and 11+ triggers for business logic, including:
+
+- Recipe recommendations and search
+- Shopping list generation from menu plans
+- Price history tracking
+- Achievement awards
+- Activity logging
+- User profile creation
+
+**Current Problem**: These database functions can fail silently in several ways:
+
+1. **`ON CONFLICT DO NOTHING`** - Swallows constraint violations without notification
+2. **`IF NOT FOUND THEN RETURN;`** - Silently exits when data is missing
+3. **Trigger functions returning `NULL`** - No indication of partial failures
+4. **No logging inside functions** - No visibility into function execution
+
+When these silent failures occur:
+
+- The application layer receives no error (function "succeeds" but does nothing)
+- No logs are generated for debugging
+- Issues are only discovered when users report missing data
+- Root cause analysis is extremely difficult
+
+**Example of Silent Failure**:
+
+```sql
+-- This function silently does nothing if achievement doesn't exist
+CREATE OR REPLACE FUNCTION public.award_achievement(p_user_id UUID, p_achievement_name TEXT)
+RETURNS void AS $$
+BEGIN
+    SELECT achievement_id INTO v_achievement_id FROM achievements WHERE name = p_achievement_name;
+    IF v_achievement_id IS NULL THEN
+        RETURN;  -- Silent failure - no log, no error
+    END IF;
+    -- ...
+END;
+$$;
+```
+
+ADR-015 established Logstash + Bugsink for error tracking, with PostgreSQL log integration marked as "future". This ADR defines the implementation.
+
+## Decision
+
+We will implement a standardized PostgreSQL function observability strategy with three tiers of logging severity:
+
+### 1. Function Logging Helper
+
+Create a reusable logging function that outputs structured JSON to PostgreSQL logs:
+
+```sql
+-- Function to emit structured log messages from PL/pgSQL
+CREATE OR REPLACE FUNCTION public.fn_log(
+    p_level TEXT,           -- 'DEBUG', 'INFO', 'NOTICE', 'WARNING', 'ERROR'
+    p_function_name TEXT,   -- The calling function name
+    p_message TEXT,         -- Human-readable message
+    p_context JSONB DEFAULT NULL  -- Additional context (user_id, params, etc.)
+)
+RETURNS void
+LANGUAGE plpgsql
+AS $$
+DECLARE
+    log_line TEXT;
+BEGIN
+    -- Build structured JSON log line
+    log_line := jsonb_build_object(
+        'timestamp', now(),
+        'level', p_level,
+        'source', 'postgresql',
+        'function', p_function_name,
+        'message', p_message,
+        'context', COALESCE(p_context, '{}'::jsonb)
+    )::text;
+
+    -- Use appropriate RAISE level
+    CASE p_level
+        WHEN 'DEBUG' THEN RAISE DEBUG '%', log_line;
+        WHEN 'INFO' THEN RAISE INFO '%', log_line;
+        WHEN 'NOTICE' THEN RAISE NOTICE '%', log_line;
+        WHEN 'WARNING' THEN RAISE WARNING '%', log_line;
+        WHEN 'ERROR' THEN RAISE LOG '%', log_line;  -- Use LOG for errors to ensure capture
+        ELSE RAISE NOTICE '%', log_line;
+    END CASE;
+END;
+$$;
+```
+
+### 2. Logging Tiers
+
+#### Tier 1: Critical Functions (Always Log)
+
+Functions where silent failure causes data corruption or user-facing issues:
+
+| Function                           | Log Events                              |
+| ---------------------------------- | --------------------------------------- |
+| `handle_new_user()`                | User creation, profile creation, errors |
+| `award_achievement()`              | Achievement not found, already awarded  |
+| `approve_correction()`             | Correction not found, permission denied |
+| `complete_shopping_list()`         | List not found, permission denied       |
+| `add_menu_plan_to_shopping_list()` | Permission denied, items added          |
+| `fork_recipe()`                    | Original not found, fork created        |
+
+**Pattern**:
+
+```sql
+CREATE OR REPLACE FUNCTION public.award_achievement(p_user_id UUID, p_achievement_name TEXT)
+RETURNS void AS $$
+DECLARE
+    v_achievement_id BIGINT;
+    v_points_value INTEGER;
+    v_context JSONB;
+BEGIN
+    v_context := jsonb_build_object('user_id', p_user_id, 'achievement_name', p_achievement_name);
+
+    SELECT achievement_id, points_value INTO v_achievement_id, v_points_value
+    FROM public.achievements WHERE name = p_achievement_name;
+
+    IF v_achievement_id IS NULL THEN
+        -- Log the issue instead of silent return
+        PERFORM fn_log('WARNING', 'award_achievement',
+            'Achievement not found: ' || p_achievement_name, v_context);
+        RETURN;
+    END IF;
+
+    INSERT INTO public.user_achievements (user_id, achievement_id)
+    VALUES (p_user_id, v_achievement_id)
+    ON CONFLICT (user_id, achievement_id) DO NOTHING;
+
+    IF FOUND THEN
+        UPDATE public.profiles SET points = points + v_points_value WHERE user_id = p_user_id;
+        PERFORM fn_log('INFO', 'award_achievement',
+            'Achievement awarded: ' || p_achievement_name, v_context);
+    END IF;
+END;
+$$;
+```
+
+#### Tier 2: Business Logic Functions (Log on Anomalies)
+
+Functions where unexpected conditions should be logged but aren't critical:
+
+| Function                               | Log Events                         |
+| -------------------------------------- | ---------------------------------- |
+| `suggest_master_item_for_flyer_item()` | No match found (below threshold)   |
+| `recommend_recipes_for_user()`         | No recommendations generated       |
+| `find_recipes_from_pantry()`           | Empty pantry, no recipes found     |
+| `get_best_sale_prices_for_user()`      | No watched items, no current sales |
+
+**Pattern**: Log when results are unexpectedly empty or inputs are invalid.
+
+#### Tier 3: Triggers (Log Errors Only)
+
+Triggers should be fast, so only log when something goes wrong:
+
+| Trigger Function                              | Log Events                |
+| --------------------------------------------- | ------------------------- |
+| `update_price_history_on_flyer_item_insert()` | Failed to update history  |
+| `update_recipe_rating_aggregates()`           | Rating calculation failed |
+| `log_new_recipe()`                            | Profile lookup failed     |
+| `log_new_flyer()`                             | Store lookup failed       |
+
+### 3. PostgreSQL Configuration
+
+Enable logging in `postgresql.conf`:
+
+```ini
+# Log all function notices and above
+log_min_messages = notice
+
+# Include function name in log prefix
+log_line_prefix = '%t [%p] %u@%d '
+
+# Log to file for Logstash pickup
+logging_collector = on
+log_directory = '/var/log/postgresql'
+log_filename = 'postgresql-%Y-%m-%d.log'
+log_rotation_age = 1d
+log_rotation_size = 100MB
+
+# Capture slow queries from functions
+log_min_duration_statement = 1000  # Log queries over 1 second
+```
+
+### 4. Logstash Integration
+
+Update the Logstash pipeline (extends ADR-015 configuration):
+
+```conf
+# PostgreSQL function log input
+input {
+  file {
+    path => "/var/log/postgresql/*.log"
+    type => "postgres"
+    tags => ["postgres"]
+    start_position => "beginning"
+    sincedb_path => "/var/lib/logstash/sincedb_postgres"
+  }
+}
+
+filter {
+  if [type] == "postgres" {
+    # Extract timestamp and process ID from PostgreSQL log prefix
+    grok {
+      match => { "message" => "%{TIMESTAMP_ISO8601:pg_timestamp} \[%{POSINT:pg_pid}\] %{USER:pg_user}@%{WORD:pg_database} %{GREEDYDATA:pg_message}" }
+    }
+
+    # Check if this is a structured JSON log from fn_log()
+    if [pg_message] =~ /^\{.*"source":"postgresql".*\}$/ {
+      json {
+        source => "pg_message"
+        target => "fn_log"
+      }
+
+      # Mark as error if level is WARNING or ERROR
+      if [fn_log][level] in ["WARNING", "ERROR"] {
+        mutate { add_tag => ["error", "db_function"] }
+      }
+    }
+
+    # Also catch native PostgreSQL errors
+    if [pg_message] =~ /^ERROR:/ or [pg_message] =~ /^FATAL:/ {
+      mutate { add_tag => ["error", "postgres_native"] }
+    }
+  }
+}
+
+output {
+  if "error" in [tags] and "postgres" in [tags] {
+    http {
+      url => "http://localhost:8000/api/store/"
+      http_method => "post"
+      format => "json"
+    }
+  }
+}
+```
+
+### 5. Dual-File Update Requirement
+
+**IMPORTANT**: All SQL function changes must be applied to BOTH files:
+
+1. `sql/Initial_triggers_and_functions.sql` - Used for incremental updates
+2. `sql/master_schema_rollup.sql` - Used for fresh database setup
+
+Both files must remain in sync for triggers and functions.
+
+## Implementation Steps
+
+1. **Create `fn_log()` helper function**:
+   - Add to both `Initial_triggers_and_functions.sql` and `master_schema_rollup.sql`
+   - Test with `SELECT fn_log('INFO', 'test', 'Test message', '{"key": "value"}'::jsonb);`
+
+2. **Update Tier 1 critical functions** (highest priority):
+   - `award_achievement()` - Log missing achievements, duplicate awards
+   - `handle_new_user()` - Log user creation success/failure
+   - `approve_correction()` - Log not found, permission denied
+   - `complete_shopping_list()` - Log permission checks
+   - `add_menu_plan_to_shopping_list()` - Log permission checks, items added
+   - `fork_recipe()` - Log original not found
+
+3. **Update Tier 2 business logic functions**:
+   - Add anomaly logging to suggestion/recommendation functions
+   - Log empty result sets with context
+
+4. **Update Tier 3 trigger functions**:
+   - Add error-only logging to critical triggers
+   - Wrap complex trigger logic in exception handlers
+
+5. **Configure PostgreSQL logging**:
+   - Update `postgresql.conf` in dev container
+   - Update production PostgreSQL configuration
+   - Verify logs appear in expected location
+
+6. **Update Logstash pipeline**:
+   - Add PostgreSQL input to `bugsink.conf`
+   - Add filter rules for structured JSON extraction
+   - Test end-to-end: function log → Logstash → Bugsink
+
+7. **Verify in Bugsink**:
+   - Confirm database function errors appear as issues
+   - Verify context (user_id, function name, params) is captured
+
+## Consequences
+
+### Positive
+
+- **Visibility**: Silent failures become visible in error tracking
+- **Debugging**: Function execution context captured for root cause analysis
+- **Proactive detection**: Anomalies logged before users report issues
+- **Unified monitoring**: Database errors appear alongside application errors in Bugsink
+- **Structured logs**: JSON format enables filtering and aggregation
+
+### Negative
+
+- **Performance overhead**: Logging adds latency to function execution
+- **Log volume**: Tier 1/2 functions may generate significant log volume
+- **Maintenance**: Two SQL files must be kept in sync
+- **PostgreSQL configuration**: Requires access to `postgresql.conf`
+
+### Mitigations
+
+- **Performance**: Only log meaningful events, not every function call
+- **Log volume**: Use appropriate log levels; Logstash filters reduce noise
+- **Sync**: Add CI check to verify SQL files match for function definitions
+- **Configuration**: Document PostgreSQL settings in deployment runbook
+
+## Examples
+
+### Before (Silent Failure)
+
+```sql
+-- User thinks achievement was awarded, but it silently failed
+SELECT award_achievement('user-uuid', 'Nonexistent Badge');
+-- Returns: void (no error, no log)
+-- Result: User never gets achievement, nobody knows why
+```
+
+### After (Observable Failure)
+
+```sql
+SELECT award_achievement('user-uuid', 'Nonexistent Badge');
+-- Returns: void
+-- PostgreSQL log: {"timestamp":"2026-01-11T10:30:00Z","level":"WARNING","source":"postgresql","function":"award_achievement","message":"Achievement not found: Nonexistent Badge","context":{"user_id":"user-uuid","achievement_name":"Nonexistent Badge"}}
+-- Bugsink: New issue created with full context
+```

+# ADR-051: Asynchronous Context Propagation
+
+**Date**: 2026-01-11
+
+**Status**: Accepted (Implemented)
+
+## Context
+
+Debugging asynchronous workflows is difficult because the `request_id` generated at the API layer is lost when a task is handed off to a background queue (BullMQ). Logs from the worker appear disconnected from the user action that triggered them.
+
+## Decision
+
+We will implement a context propagation pattern for all background jobs:
+
+1. **Job Data Payload**: All job data interfaces MUST include a `meta` object containing `requestId`, `userId`, and `origin`.
+2. **Worker Logger Initialization**: All BullMQ workers MUST initialize a child logger immediately upon processing a job, using the metadata passed in the payload.
+3. **Correlation**: The worker's logger must use the _same_ `request_id` as the initiating API request.
+
+## Implementation
+
+```typescript
+// 1. Enqueueing (API Layer)
+await queue.add('process-flyer', {
+  ...data,
+  meta: {
+    requestId: req.log.bindings().request_id, // Propagate ID
+    userId: req.user.id,
+  },
+});
+
+// 2. Processing (Worker Layer)
+const worker = new Worker('queue', async (job) => {
+  const { requestId, userId } = job.data.meta || {};
+
+  // Create context-aware logger for this specific job execution
+  const jobLogger = logger.child({
+    request_id: requestId || uuidv4(), // Use propagated ID or generate new
+    user_id: userId,
+    job_id: job.id,
+    service: 'worker',
+  });
+
+  try {
+    await processJob(job.data, jobLogger); // Pass logger down
+  } catch (err) {
+    jobLogger.error({ err }, 'Job failed');
+    throw err;
+  }
+});
+```
+
+## Consequences
+
+**Positive**: Complete traceability from API request -> Queue -> Worker execution. Drastically reduces time to find "what happened" to a specific user request.

+# ADR-052: Granular Debug Logging Strategy
+
+**Date**: 2026-01-11
+
+**Status**: Proposed
+
+## Context
+
+Global log levels (INFO vs DEBUG) are too coarse. Developers need to inspect detailed debug information for specific subsystems (e.g., `ai-service`, `db-pool`) without being flooded by logs from the entire application.
+
+## Decision
+
+We will adopt a namespace-based debug filter pattern, similar to the `debug` npm package, but integrated into our Pino logger.
+
+1. **Logger Namespaces**: Every service/module logger must be initialized with a `module` property (e.g., `logger.child({ module: 'ai-service' })`).
+2. **Environment Filter**: We will support a `DEBUG_MODULES` environment variable that overrides the log level for matching modules.
+
+## Implementation
+
+In `src/services/logger.server.ts`:
+
+```typescript
+const debugModules = (process.env.DEBUG_MODULES || '').split(',').map((s) => s.trim());
+
+export const createScopedLogger = (moduleName: string) => {
+  // If DEBUG_MODULES contains "ai-service" or "*", force level to 'debug'
+  const isDebugEnabled = debugModules.includes('*') || debugModules.includes(moduleName);
+
+  return logger.child({
+    module: moduleName,
+    level: isDebugEnabled ? 'debug' : logger.level,
+  });
+};
+```
+
+## Usage
+
+To debug only AI and Database interactions:
+
+```bash
+DEBUG_MODULES=ai-service,db-repo npm run dev
+```

+# ADR-053: Worker Health Checks and Stalled Job Monitoring
+
+**Date**: 2026-01-11
+
+**Status**: Proposed
+
+## Context
+
+Our application relies heavily on background workers (BullMQ) for flyer processing, analytics, and emails. If a worker process crashes (e.g., Out of Memory) or hangs, jobs may remain in the 'active' state indefinitely ("stalled") until BullMQ's fail-safe triggers.
+
+Currently, we lack:
+
+1. Visibility into queue depths and worker status via HTTP endpoints (for uptime monitors).
+2. A mechanism to detect if the worker process itself is alive, beyond just queue statistics.
+3. Explicit configuration to ensure stalled jobs are recovered quickly.
+
+## Decision
+
+We will implement a multi-layered health check strategy for background workers:
+
+1. **Queue Metrics Endpoint**: Expose a protected endpoint `GET /health/queues` that returns the counts (waiting, active, failed) for all critical queues.
+2. **Stalled Job Configuration**: Explicitly configure BullMQ workers with aggressive stall detection settings to recover quickly from crashes.
+3. **Worker Heartbeats**: Workers will periodically update a "heartbeat" key in Redis. The health endpoint will check if this timestamp is recent.
+
+## Implementation
+
+### 1. BullMQ Worker Settings
+
+Workers must be initialized with specific options to handle stalls:
+
+```typescript
+const workerOptions = {
+  // Check for stalled jobs every 30 seconds
+  stalledInterval: 30000,
+  // Fail job after 3 stalls (prevents infinite loops causing infinite retries)
+  maxStalledCount: 3,
+  // Duration of the lock for the job in milliseconds.
+  // If the worker doesn't renew this (e.g. crash), the job stalls.
+  lockDuration: 30000,
+};
+```
+
+### 2. Health Endpoint Logic
+
+The `/health/queues` endpoint will:
+
+1. Iterate through all defined queues (`flyerQueue`, `emailQueue`, etc.).
+2. Fetch job counts (`waiting`, `active`, `failed`, `delayed`).
+3. Return a 200 OK if queues are accessible, or 503 if Redis is unreachable.
+4. (Future) Return 500 if the `waiting` count exceeds a critical threshold for too long.
+
+## Consequences
+
+**Positive**:
+
+- Early detection of stuck processing pipelines.
+- Automatic recovery of stalled jobs via BullMQ configuration.
+- Metrics available for external monitoring tools (e.g., UptimeRobot, Datadog).
+
+**Negative**:
+
+- Requires configuring external monitoring to poll the new endpoint.

+# ADR-054: Bugsink to Gitea Issue Synchronization
+
+**Date**: 2026-01-17
+
+**Status**: Proposed
+
+## Context
+
+The application uses Bugsink (Sentry-compatible self-hosted error tracking) to capture runtime errors across 6 projects:
+
+| Project                           | Type           | Environment  |
+| --------------------------------- | -------------- | ------------ |
+| flyer-crawler-backend             | Backend        | Production   |
+| flyer-crawler-backend-test        | Backend        | Test/Staging |
+| flyer-crawler-frontend            | Frontend       | Production   |
+| flyer-crawler-frontend-test       | Frontend       | Test/Staging |
+| flyer-crawler-infrastructure      | Infrastructure | Production   |
+| flyer-crawler-test-infrastructure | Infrastructure | Test/Staging |
+
+Currently, errors remain in Bugsink until manually reviewed. There is no automated workflow to:
+
+1. Create trackable tickets for errors
+2. Assign errors to developers
+3. Track resolution progress
+4. Prevent errors from being forgotten
+
+## Decision
+
+Implement an automated background worker that synchronizes unresolved Bugsink issues to Gitea as trackable tickets. The sync worker will:
+
+1. **Run only on the test/staging server** (not production, not dev container)
+2. **Poll all 6 Bugsink projects** for unresolved issues
+3. **Create Gitea issues** with full error context
+4. **Mark synced issues as resolved** in Bugsink (to prevent re-polling)
+5. **Track sync state in Redis** to ensure idempotency
+
+### Why Test/Staging Only?
+
+- The sync worker is a background service that needs API tokens for both Bugsink and Gitea
+- Running on test/staging provides a single sync point without duplicating infrastructure
+- All 6 Bugsink projects (including production) are synced from this one worker
+- Production server stays focused on serving users, not running sync jobs

+**Trace ID**: {trace_id}
+```
+
+### Sync Workflow
+
+```
+1. Worker triggered (every 15 min or manual)
+2. For each of 6 Bugsink projects:
+   a. List issues with status='unresolved'
+   b. For each issue:
+      i.   Check Redis for existing sync record
+      ii.  If already synced → skip
+      iii. Fetch issue details + stacktrace
+      iv.  Create Gitea issue with labels
+      v.   Store sync record in Redis
+      vi.  Mark issue as 'resolved' in Bugsink
+3. Log summary (synced: N, skipped: N, failed: N)
+```
+
+### Idempotency Guarantees
+
+1. **Redis check before creation**: Prevents duplicate Gitea issues
+2. **Atomic Redis write after Gitea create**: Ensures state consistency
+3. **Query only unresolved issues**: Resolved issues won't appear in polls
+4. **No TTL on Redis keys**: Permanent sync history
+
+## Consequences
+
+### Positive
+
+1. **Visibility**: All application errors become trackable tickets
+2. **Accountability**: Errors can be assigned to developers
+3. **History**: Complete audit trail of when errors were discovered and resolved
+4. **Integration**: Errors appear alongside feature work in Gitea
+5. **Automation**: No manual error triage required
+
+### Negative
+
+1. **API Dependencies**: Requires both Bugsink and Gitea APIs to be available
+2. **Token Management**: Additional secrets to manage in CI/CD
+3. **Potential Noise**: High-frequency errors could create many tickets (mitigated by Bugsink's issue grouping)
+4. **Single Point**: Sync only runs on test server (if test server is down, no sync occurs)
+
+### Risks & Mitigations
+
+| Risk                    | Mitigation                                        |
+| ----------------------- | ------------------------------------------------- |
+| Bugsink API rate limits | 15-minute polling interval                        |
+| Gitea API rate limits   | Sequential processing with delays                 |
+| Redis connection issues | Reuse existing connection patterns                |
+| Duplicate issues        | Redis tracking + idempotent checks                |
+| Missing stacktrace      | Graceful degradation (create issue without trace) |

+
+## Implementation Phases
+
+### Phase 1: Core Infrastructure
+
+- Add environment variables to `env.ts` schema
+- Create `BugsinkClient` service (HTTP client)
+- Create `GiteaClient` service (HTTP client)
+- Add Redis db 15 connection for sync tracking
+
+### Phase 2: Sync Logic
+
+- Create `BugsinkSyncService` with sync logic
+- Add `bugsink-sync` queue to `queues.server.ts`
+- Add sync worker to `workers.server.ts`
+- Create TypeScript types for API responses
+
+### Phase 3: Integration
+
+- Add admin endpoints for manual sync trigger
+- Update `deploy-to-test.yml` with new secrets
+- Add secrets to Gitea repository settings
+- Test end-to-end in staging environment
+
+### Phase 4: Documentation
+
+- Update CLAUDE.md with sync information
+- Create operational runbook for sync issues
+
+## Future Enhancements
+
+1. **Bi-directional sync**: Update Bugsink when Gitea issue is closed
+2. **Smart deduplication**: Detect similar errors across projects
+3. **Priority mapping**: High occurrence count → high priority label
+4. **Slack/Discord notifications**: Alert on new critical errors
+5. **Metrics dashboard**: Track error trends over time

+# Authentication Setup
+
+Flyer Crawler supports OAuth authentication via Google and GitHub. This guide walks through configuring both providers.
+
+---
+
+## Google OAuth
+
+### Step 1: Create OAuth Credentials
+
+1. Go to the [Google Cloud Console](https://console.cloud.google.com/)
+2. Create a new project (or select an existing one)
+3. Navigate to **APIs & Services > Credentials**
+4. Click **Create Credentials > OAuth client ID**
+5. Select **Web application** as the application type
+
+### Step 2: Configure Authorized Redirect URIs
+
+Add the callback URL where Google will redirect users after authentication:
+
+| Environment | Redirect URI                                       |
+| ----------- | -------------------------------------------------- |
+| Development | `http://localhost:3001/api/auth/google/callback`   |
+| Production  | `https://your-domain.com/api/auth/google/callback` |
+
+### Step 3: Save Credentials
+
+After clicking **Create**, you'll receive:
+
+- **Client ID**
+- **Client Secret**
+
+Store these securely as environment variables:
+
+- `GOOGLE_CLIENT_ID`
+- `GOOGLE_CLIENT_SECRET`
+
+---
+
+## GitHub OAuth

+1. Go to your [GitHub Developer Settings](https://github.com/settings/developers)
+2. Navigate to **OAuth Apps**
+3. Click **New OAuth App**
+
+### Step 2: Fill in Application Details
+
+| Field                      | Value                                                |
+| -------------------------- | ---------------------------------------------------- |
+| Application name           | Flyer Crawler (or your preferred name)               |
+| Homepage URL               | `http://localhost:5173` (dev) or your production URL |
+| Authorization callback URL | `http://localhost:3001/api/auth/github/callback`     |
+
+### Step 3: Save GitHub Credentials
+
+After clicking **Register application**, you'll receive:
+
+- **Client ID**
+- **Client Secret**
+
+Store these securely as environment variables:
+
+- `GITHUB_CLIENT_ID`
+- `GITHUB_CLIENT_SECRET`
+
+---
+
+## Environment Variables Summary
+
+| Variable               | Description                              |
+| ---------------------- | ---------------------------------------- |
+| `GOOGLE_CLIENT_ID`     | Google OAuth client ID                   |
+| `GOOGLE_CLIENT_SECRET` | Google OAuth client secret               |
+| `GITHUB_CLIENT_ID`     | GitHub OAuth client ID                   |
+| `GITHUB_CLIENT_SECRET` | GitHub OAuth client secret               |
+| `JWT_SECRET`           | Secret for signing authentication tokens |
+
+---
+
+## Production Considerations
+
+When deploying to production:
+
+1. **Update redirect URIs** in both Google Cloud Console and GitHub OAuth settings to use your production domain
+2. **Use HTTPS** for all callback URLs in production
+3. **Store secrets securely** using your CI/CD platform's secrets management (e.g., Gitea repository secrets)
+
+---
+
+## Troubleshooting
+
+### "redirect_uri_mismatch" Error
+
+The callback URL in your OAuth provider settings doesn't match what the application is sending. Verify:
+
+- The URL is exactly correct (no trailing slashes, correct port)
+- You're using the right environment (dev vs production URLs)
+
+### "invalid_client" Error
+
+The Client ID or Client Secret is incorrect. Double-check your environment variables.

+# Database Setup
+
+Flyer Crawler uses PostgreSQL with several extensions for full-text search, geographic data, and UUID generation.
+
+---
+
+## Required Extensions
+
+| Extension   | Purpose                                     |
+| ----------- | ------------------------------------------- |
+| `postgis`   | Geographic/spatial data for store locations |
+| `pg_trgm`   | Trigram matching for fuzzy text search      |
+| `uuid-ossp` | UUID generation for primary keys            |
+
+---
+
+## Database Users
+
+This project uses **environment-specific database users** to isolate production and test environments:
+
+| User                 | Database             | Purpose    |
+| -------------------- | -------------------- | ---------- |
+| `flyer_crawler_prod` | `flyer-crawler-prod` | Production |
+| `flyer_crawler_test` | `flyer-crawler-test` | Testing    |
+
+---
+
+## Production Database Setup
+
+### Step 1: Install PostgreSQL
+
+```bash
+sudo apt update
+sudo apt install postgresql postgresql-contrib
+```
+
+### Step 2: Create Database and User
+
+Switch to the postgres system user:
+
+```bash
+sudo -u postgres psql
+```
+
+Run the following SQL commands (replace `'a_very_strong_password'` with a secure password):
+
+```sql
+-- Create the production role
+CREATE ROLE flyer_crawler_prod WITH LOGIN PASSWORD 'a_very_strong_password';
+
+-- Create the production database
+CREATE DATABASE "flyer-crawler-prod" WITH OWNER = flyer_crawler_prod;
+
+-- Connect to the new database
+\c "flyer-crawler-prod"
+
+-- Grant schema privileges
+ALTER SCHEMA public OWNER TO flyer_crawler_prod;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_prod;
+
+-- Install required extensions (must be done as superuser)
+CREATE EXTENSION IF NOT EXISTS postgis;
+CREATE EXTENSION IF NOT EXISTS pg_trgm;
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+
+-- Exit
+\q
+```
+
+### Step 3: Apply the Schema
+
+Navigate to your project directory and run:
+
+```bash
+psql -U flyer_crawler_prod -d "flyer-crawler-prod" -f sql/master_schema_rollup.sql
+```
+
+This creates all tables, functions, triggers, and seeds essential data (categories, master items).
+
+### Step 4: Seed the Admin Account
+
+Set the required environment variables and run the seed script:
+
+```bash
+export DB_USER=flyer_crawler_prod
+export DB_PASSWORD=your_password
+export DB_NAME="flyer-crawler-prod"
+export DB_HOST=localhost
+
+npx tsx src/db/seed_admin_account.ts
+```
+
+---
+
+## Test Database Setup
+
+The test database is used by CI/CD pipelines and local test runs.
+
+### Step 1: Create the Test Database
+
+```bash
+sudo -u postgres psql
+```
+
+```sql
+-- Create the test role
+CREATE ROLE flyer_crawler_test WITH LOGIN PASSWORD 'a_very_strong_password';
+
+-- Create the test database
+CREATE DATABASE "flyer-crawler-test" WITH OWNER = flyer_crawler_test;
+
+-- Connect to the test database
+\c "flyer-crawler-test"
+
+-- Grant schema privileges (required for test runner to reset schema)
+ALTER SCHEMA public OWNER TO flyer_crawler_test;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_test;
+
+-- Install required extensions
+CREATE EXTENSION IF NOT EXISTS postgis;
+CREATE EXTENSION IF NOT EXISTS pg_trgm;
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+
+-- Exit
+\q
+```
+
+### Step 2: Configure CI/CD Secrets
+
+Ensure these secrets are set in your Gitea repository settings:
+
+**Shared:**
+
+| Secret    | Description                           |
+| --------- | ------------------------------------- |
+| `DB_HOST` | Database hostname (e.g., `localhost`) |
+| `DB_PORT` | Database port (e.g., `5432`)          |
+
+**Production-specific:**
+
+| Secret             | Description                                     |
+| ------------------ | ----------------------------------------------- |
+| `DB_USER_PROD`     | Production database user (`flyer_crawler_prod`) |
+| `DB_PASSWORD_PROD` | Production database password                    |
+| `DB_DATABASE_PROD` | Production database name (`flyer-crawler-prod`) |
+
+**Test-specific:**
+
+| Secret             | Description                               |
+| ------------------ | ----------------------------------------- |
+| `DB_USER_TEST`     | Test database user (`flyer_crawler_test`) |
+| `DB_PASSWORD_TEST` | Test database password                    |
+| `DB_DATABASE_TEST` | Test database name (`flyer-crawler-test`) |
+
+---
+
+## How the Test Pipeline Works
+
+The CI pipeline uses a permanent test database that gets reset on each test run:
+
+1. **Setup**: The vitest global setup script connects to `flyer-crawler-test`
+2. **Schema Reset**: Executes `sql/drop_tables.sql` (`DROP SCHEMA public CASCADE`)
+3. **Schema Application**: Runs `sql/master_schema_rollup.sql` to build a fresh schema
+4. **Test Execution**: Tests run against the clean database
+
+This approach is faster than creating/destroying databases and doesn't require sudo access.
+
+---
+
+## Connecting to Production Database
+
+```bash
+psql -h localhost -U flyer_crawler_prod -d "flyer-crawler-prod" -W
+```
+
+---
+
+## Checking PostGIS Version
+
+```sql
+SELECT version();
+SELECT PostGIS_Full_Version();
+```
+
+Example output:
+
+```text
+PostgreSQL 14.19 (Ubuntu 14.19-0ubuntu0.22.04.1)
+POSTGIS="3.2.0 c3e3cc0" GEOS="3.10.2-CAPI-1.16.0" PROJ="8.2.1"
+```
+
+---
+
+## Schema Files
+
+| File                           | Purpose                                                   |
+| ------------------------------ | --------------------------------------------------------- |
+| `sql/master_schema_rollup.sql` | Complete schema with all tables, functions, and seed data |
+| `sql/drop_tables.sql`          | Drops entire schema (used by test runner)                 |
+| `sql/schema.sql.txt`           | Legacy schema file (reference only)                       |
+
+---
+
+## Backup and Restore
+
+### Create a Backup
+
+```bash
+pg_dump -U flyer_crawler_prod -d "flyer-crawler-prod" -F c -f backup.dump
+```
+
+### Restore from Backup
+
+```bash
+pg_restore -U flyer_crawler_prod -d "flyer-crawler-prod" -c backup.dump
+```

+```
+
+### Detailed Processing Steps
+
+1. **Upload**: User uploads flyer image via `/api/flyers/upload`
+2. **Validation**: Server validates file type, size, and generates checksum
+3. **Queueing**: Job added to `flyer-processing` queue with file path
+4. **Worker Pickup**: BullMQ worker picks up job for processing
+5. **AI Extraction**: Google Gemini analyzes image and extracts:
+   - Store name
+   - Valid date range
+   - Store address (if present)
+   - Deal items (name, price, quantity, category)
+6. **Data Transformation**: Raw AI output transformed to database schema
+7. **Persistence**: Transactional insert of flyer + items + store
+8. **Cache Invalidation**: Redis cache cleared for affected queries
+9. **Notification**: WebSocket message sent to user with results
+10. **Cleanup**: Temporary files scheduled for deletion

+
+### Job Lifecycle
+
+1. **Queued**: Job added to queue with data payload
+2. **Active**: Worker picks up job and begins processing
+3. **Completed**: Job finishes successfully
+4. **Failed**: Job encounters error, may retry
+5. **Delayed**: Job waiting for retry backoff
+
+### Retry Strategy
+
+Jobs use exponential backoff for retries:
+
+```
+Attempt 1: Immediate
+Attempt 2: Initial delay (e.g., 5 seconds)
+Attempt 3: 2x delay (e.g., 10 seconds)
+Attempt 4: 4x delay (e.g., 20 seconds)
+...

+# WebSocket Real-Time Notifications - Usage Guide
+
+This guide shows you how to use the WebSocket real-time notification system in your React components.
+
+## Quick Start
+
+### 1. Enable Global Notifications
+
+Add the `NotificationToastHandler` to your root `App.tsx`:
+
+```tsx
+// src/App.tsx
+import { Toaster } from 'react-hot-toast';
+import { NotificationToastHandler } from './components/NotificationToastHandler';
+
+function App() {
+  return (
+    <>
+      {/* React Hot Toast container */}
+      <Toaster position="top-right" />
+
+      {/* WebSocket notification handler (renders nothing, handles side effects) */}
+      <NotificationToastHandler
+        enabled={true}
+        playSound={false} // Set to true to play notification sounds
+      />
+
+      {/* Your app routes and components */}
+      <YourAppContent />
+    </>
+  );
+}
+```
+
+### 2. Add Notification Bell to Header
+
+```tsx
+// src/components/Header.tsx
+import { NotificationBell } from './components/NotificationBell';
+import { useNavigate } from 'react-router-dom';
+
+function Header() {
+  const navigate = useNavigate();
+
+  return (
+    <header className="flex items-center justify-between p-4">
+      <h1>Flyer Crawler</h1>
+
+      <div className="flex items-center gap-4">
+        {/* Notification bell with unread count */}
+        <NotificationBell onClick={() => navigate('/notifications')} showConnectionStatus={true} />
+
+        <UserMenu />
+      </div>
+    </header>
+  );
+}
+```
+
+### 3. Listen for Notifications in Components
+
+```tsx
+// src/pages/DealsPage.tsx
+import { useEventBus } from '../hooks/useEventBus';
+import { useCallback, useState } from 'react';
+import type { DealNotificationData } from '../types/websocket';
+
+function DealsPage() {
+  const [deals, setDeals] = useState([]);
+
+  // Listen for new deal notifications
+  const handleDealNotification = useCallback((data: DealNotificationData) => {
+    console.log('New deals received:', data.deals);
+
+    // Update your deals list
+    setDeals((prev) => [...data.deals, ...prev]);
+
+    // Or refetch from API
+    // refetchDeals();
+  }, []);
+
+  useEventBus('notification:deal', handleDealNotification);
+
+  return (
+    <div>
+      <h1>Deals</h1>
+      {/* Render deals */}
+    </div>
+  );
+}
+```
+
+## Available Components
+
+### `NotificationBell`
+
+A notification bell icon with unread count and connection status indicator.
+
+**Props:**
+
+- `onClick?: () => void` - Callback when bell is clicked
+- `showConnectionStatus?: boolean` - Show green/red/yellow connection dot (default: `true`)
+- `className?: string` - Custom CSS classes
+
+**Example:**
+
+```tsx
+<NotificationBell
+  onClick={() => navigate('/notifications')}
+  showConnectionStatus={true}
+  className="mr-4"
+/>
+```
+
+### `ConnectionStatus`
+
+A simple status indicator showing if WebSocket is connected (no bell icon).
+
+**Example:**
+
+```tsx
+<ConnectionStatus />
+```
+
+### `NotificationToastHandler`
+
+Global handler that listens for WebSocket events and displays toasts. Should be rendered once at app root.
+
+**Props:**
+
+- `enabled?: boolean` - Enable/disable toast notifications (default: `true`)
+- `playSound?: boolean` - Play sound on notifications (default: `false`)
+- `soundUrl?: string` - Custom notification sound URL
+
+**Example:**
+
+```tsx
+<NotificationToastHandler enabled={true} playSound={true} soundUrl="/custom-sound.mp3" />
+```
+
+## Available Hooks
+
+### `useWebSocket`
+
+Connect to the WebSocket server and manage connection state.
+
+**Options:**
+
+- `autoConnect?: boolean` - Auto-connect on mount (default: `true`)
+- `maxReconnectAttempts?: number` - Max reconnect attempts (default: `5`)
+- `reconnectDelay?: number` - Base reconnect delay in ms (default: `1000`)
+- `onConnect?: () => void` - Callback on connection
+- `onDisconnect?: () => void` - Callback on disconnect
+- `onError?: (error: Event) => void` - Callback on error
+
+**Returns:**
+
+- `isConnected: boolean` - Connection status
+- `isConnecting: boolean` - Connecting state
+- `error: string | null` - Error message if any
+- `connect: () => void` - Manual connect function
+- `disconnect: () => void` - Manual disconnect function
+- `send: (message: WebSocketMessage) => void` - Send message to server
+
+**Example:**
+
+```tsx
+const { isConnected, error, connect, disconnect } = useWebSocket({
+  autoConnect: true,
+  maxReconnectAttempts: 3,
+  onConnect: () => console.log('Connected!'),
+  onDisconnect: () => console.log('Disconnected!'),
+});
+
+return (
+  <div>
+    <p>Status: {isConnected ? 'Connected' : 'Disconnected'}</p>
+    {error && <p>Error: {error}</p>}
+    <button onClick={connect}>Reconnect</button>
+  </div>
+);
+```
+
+### `useEventBus`
+
+Subscribe to event bus events (used with WebSocket integration).
+
+**Parameters:**
+
+- `event: string` - Event name to listen for
+- `callback: (data?: T) => void` - Callback function
+
+**Available Events:**
+
+- `'notification:deal'` - Deal notifications (`DealNotificationData`)
+- `'notification:system'` - System messages (`SystemMessageData`)
+- `'notification:error'` - Error messages (`{ message: string; code?: string }`)
+
+**Example:**
+
+```tsx
+import { useEventBus } from '../hooks/useEventBus';
+import type { DealNotificationData } from '../types/websocket';
+
+function MyComponent() {
+  useEventBus<DealNotificationData>('notification:deal', (data) => {
+    console.log('Received deal:', data);
+  });
+
+  return <div>Listening for deals...</div>;
+}
+```
+
+## Message Types
+
+### Deal Notification
+
+```typescript
+interface DealNotificationData {
+  notification_id?: string;
+  deals: Array<{
+    item_name: string;
+    best_price_in_cents: number;
+    store_name: string;
+    store_id: string;
+  }>;
+  user_id: string;
+  message: string;
+}
+```
+
+### System Message
+
+```typescript
+interface SystemMessageData {
+  message: string;
+  severity: 'info' | 'warning' | 'error';
+}
+```
+
+## Advanced Usage
+
+### Custom Notification Handling
+
+If you don't want to use the default `NotificationToastHandler`, you can create your own:
+
+```tsx
+import { useWebSocket } from '../hooks/useWebSocket';
+import { useEventBus } from '../hooks/useEventBus';
+import type { DealNotificationData } from '../types/websocket';
+
+function CustomNotificationHandler() {
+  const { isConnected } = useWebSocket({ autoConnect: true });
+
+  useEventBus<DealNotificationData>('notification:deal', (data) => {
+    // Custom handling - e.g., update Redux store
+    dispatch(addDeals(data.deals));
+
+    // Show custom UI
+    showCustomNotification(data.message);
+  });
+
+  return null; // Or return your custom UI
+}
+```
+
+### Conditional WebSocket Connection
+
+```tsx
+import { useWebSocket } from '../hooks/useWebSocket';
+import { useAuth } from '../hooks/useAuth';
+
+function ConditionalWebSocket() {
+  const { user } = useAuth();
+
+  // Only connect if user is logged in
+  useWebSocket({
+    autoConnect: !!user,
+  });
+
+  return null;
+}
+```
+
+### Send Messages to Server
+
+```tsx
+import { useWebSocket } from '../hooks/useWebSocket';
+
+function PingComponent() {
+  const { send, isConnected } = useWebSocket();
+
+  const sendPing = () => {
+    send({
+      type: 'ping',
+      data: {},
+      timestamp: new Date().toISOString(),
+    });
+  };
+
+  return (
+    <button onClick={sendPing} disabled={!isConnected}>
+      Send Ping
+    </button>
+  );
+}
+```
+
+## Admin Monitoring
+
+### Get WebSocket Stats
+
+Admin users can check WebSocket connection statistics:
+
+```bash
+# Get connection stats
+curl -H "Authorization: Bearer <admin-token>" \
+  http://localhost:3001/api/admin/websocket/stats
+```
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "data": {
+    "totalUsers": 42,
+    "totalConnections": 67
+  }
+}
+```
+
+### Admin Dashboard Integration
+
+```tsx
+import { useEffect, useState } from 'react';
+
+function AdminWebSocketStats() {
+  const [stats, setStats] = useState({ totalUsers: 0, totalConnections: 0 });
+
+  useEffect(() => {
+    const fetchStats = async () => {
+      const response = await fetch('/api/admin/websocket/stats', {
+        headers: { Authorization: `Bearer ${token}` },
+      });
+      const data = await response.json();
+      setStats(data.data);
+    };
+
+    fetchStats();
+    const interval = setInterval(fetchStats, 5000); // Poll every 5s
+
+    return () => clearInterval(interval);
+  }, []);
+
+  return (
+    <div className="p-4 border rounded">
+      <h3>WebSocket Stats</h3>
+      <p>Connected Users: {stats.totalUsers}</p>
+      <p>Total Connections: {stats.totalConnections}</p>
+    </div>
+  );
+}
+```
+
+## Troubleshooting
+
+### Connection Issues
+
+1. **Check JWT Token**: WebSocket requires a valid JWT token in cookies or query string
+2. **Check Server Logs**: Look for WebSocket connection errors in server logs
+3. **Check Browser Console**: WebSocket errors are logged to console
+4. **Verify Path**: WebSocket server is at `ws://localhost:3001/ws` (or `wss://` for HTTPS)
+
+### Not Receiving Notifications
+
+1. **Check Connection Status**: Use `<ConnectionStatus />` to verify connection
+2. **Verify Event Name**: Ensure you're listening to the correct event (`notification:deal`, etc.)
+3. **Check User ID**: Notifications are sent to specific users - verify JWT user_id matches
+
+### High Memory Usage
+
+1. **Connection Leaks**: Ensure components using `useWebSocket` are properly unmounting
+2. **Event Listeners**: `useEventBus` automatically cleans up, but verify no manual listeners remain
+3. **Check Stats**: Use `/api/admin/websocket/stats` to monitor connection count
+
+## Testing
+
+### Unit Tests
+
+```typescript
+import { renderHook } from '@testing-library/react';
+import { useWebSocket } from '../hooks/useWebSocket';
+
+describe('useWebSocket', () => {
+  it('should connect automatically', () => {
+    const { result } = renderHook(() => useWebSocket({ autoConnect: true }));
+    expect(result.current.isConnecting).toBe(true);
+  });
+});
+```
+
+### Integration Tests

+## Key Achievement
+
+**ALL PHASES COMPLETE**. The normalized structure (stores → store_locations → addresses) is now fully integrated:
+
+- ✅ Database layer with full test coverage (59 tests)
+- ✅ TypeScript types and interfaces
+- ✅ REST API with 7 endpoints (17 route tests)
+- ✅ All E2E tests (3) using normalized structure
+- ✅ All integration tests (5) using normalized structure
+- ✅ Test helpers for easy store+address creation
+- ✅ All database queries returning store data now include addresses (5 queries updated)
+- ✅ Full admin UI for store management (CRUD operations)
+- ✅ Store display components for frontend use
+- ✅ Mock factories for all store-related types (3 new functions)
+- ✅ Cache invalidation for all store operations (5 endpoints)
+
+**What's Working:**
+
+- Stores can be created with or without addresses
+- Multiple locations per store are supported
+- Full CRUD operations via API with automatic cache invalidation
+- Admin can manage stores through web UI at `/admin/stores`
+- Type-safe throughout the stack
+- All flyers, deals, and admin queries include full store address information
+- StoreCard component available for displaying stores in flyer/deal listings
+- Mock factories available for testing components
+- Redis cache automatically invalidated on store mutations
+
+**No breaking changes** - existing code continues to work. Addresses are optional (stores can exist without locations).

+# Store Address Normalization Implementation Plan
+
+## Executive Summary
+
+**Problem**: The database schema has a properly normalized structure for stores and addresses (`stores` → `store_locations` → `addresses`), but the application code does NOT fully utilize this structure. Currently:
+
+- TypeScript types exist (`Store`, `Address`, `StoreLocation`) ✅
+- AddressRepository exists for basic CRUD ✅
+- E2E tests now create data using normalized structure ✅
+- **BUT**: No functionality to CREATE/MANAGE stores with addresses in the application
+- **BUT**: No API endpoints to handle store location data
+- **BUT**: No frontend forms to input address data when creating stores
+- **BUT**: Queries don't join stores with their addresses for display
+
+**Impact**: Users see stores without addresses, making features like "deals near me", "store finder", and location-based features impossible.
+
+---
+
+## Current State Analysis
+
+### ✅ What EXISTS and WORKS:
+
+1. **Database Schema**: Properly normalized (stores, addresses, store_locations)
+2. **TypeScript Types** ([src/types.ts](src/types.ts)):
+   - `Store` type (lines 2-9)
+   - `Address` type (lines 712-724)
+   - `StoreLocation` type (lines 704-710)
+3. **AddressRepository** ([src/services/db/address.db.ts](src/services/db/address.db.ts)):
+   - `getAddressById()`
+   - `upsertAddress()`
+4. **Test Helpers** ([src/tests/utils/storeHelpers.ts](src/tests/utils/storeHelpers.ts)):
+   - `createStoreWithLocation()` - for test data creation
+   - `cleanupStoreLocations()` - for test cleanup
+
+### ❌ What's MISSING:
+
+1. **No StoreRepository/StoreService** - No database layer for stores
+2. **No StoreLocationRepository** - No functions to link stores to addresses
+3. **No API endpoints** for:
+   - POST /api/stores - Create store with address
+   - GET /api/stores/:id - Get store with address(es)
+   - PUT /api/stores/:id - Update store details
+   - POST /api/stores/:id/locations - Add location to store
+   - etc.
+4. **No frontend components** for:
+   - Store creation form (with address fields)
+   - Store editing form
+   - Store location display
+5. **Queries don't join** - Existing queries (admin.db.ts, flyer.db.ts) join stores but don't include address data
+6. **No store management UI** - Admin dashboard doesn't have store management
+
+---
+
+## Detailed Investigation Findings
+
+### Places Where Stores Are Used (Need Address Data):
+
+1. **Flyer Display** ([src/features/flyer/FlyerDisplay.tsx](src/features/flyer/FlyerDisplay.tsx))
+   - Shows store name, but could show "Store @ 123 Main St, Toronto"
+
+2. **Deal Listings** (deals.db.ts queries)
+   - `deal_store_name` field exists (line 691 in types.ts)
+   - Should show "Milk $4.99 @ Store #123 (456 Oak Ave)"
+
+3. **Receipt Processing** (receipt.db.ts)
+   - Receipts link to store_id
+   - Could show "Receipt from Store @ 789 Budget St"
+
+4. **Admin Dashboard** (admin.db.ts)
+   - Joins stores for flyer review (line 720)
+   - Should show store address in admin views
+
+5. **Flyer Item Analysis** (admin.db.ts line 334)
+   - Joins stores for unmatched items
+   - Address context would help with store identification
+
+### Test Files That Need Updates:
+
+**Unit Tests** (may need store+address mocks):
+
+- src/services/db/flyer.db.test.ts
+- src/services/db/receipt.db.test.ts
+- src/services/aiService.server.test.ts
+- src/features/flyer/\*.test.tsx (various component tests)
+
+**Integration Tests** (create stores):
+
+- src/tests/integration/admin.integration.test.ts (line 164: INSERT INTO stores)
+- src/tests/integration/flyer.integration.test.ts (line 28: INSERT INTO stores)
+- src/tests/integration/price.integration.test.ts (line 48: INSERT INTO stores)
+- src/tests/integration/public.routes.integration.test.ts (line 66: INSERT INTO stores)
+- src/tests/integration/receipt.integration.test.ts (line 252: INSERT INTO stores)
+
+**E2E Tests** (already fixed):
+
+- ✅ src/tests/e2e/deals-journey.e2e.test.ts
+- ✅ src/tests/e2e/budget-journey.e2e.test.ts
+- ✅ src/tests/e2e/receipt-journey.e2e.test.ts

+
+## Implementation Plan (NO CODE YET - APPROVAL REQUIRED)
+
+### Phase 1: Database Layer (Foundation)
+
+#### 1.1 Create StoreRepository ([src/services/db/store.db.ts](src/services/db/store.db.ts))
+
+Functions needed:
+
+- `getStoreById(storeId)` - Returns Store (basic)
+- `getStoreWithLocations(storeId)` - Returns Store + Address[]
+- `getAllStores()` - Returns Store[] (basic)
+- `getAllStoresWithLocations()` - Returns Array<Store & {locations: Address[]}>
+- `createStore(name, logoUrl?, createdBy?)` - Returns storeId
+- `updateStore(storeId, updates)` - Updates name/logo
+- `deleteStore(storeId)` - Cascades to store_locations
+- `searchStoresByName(query)` - For autocomplete
+
+**Test file**: [src/services/db/store.db.test.ts](src/services/db/store.db.test.ts)
+
+#### 1.2 Create StoreLocationRepository ([src/services/db/storeLocation.db.ts](src/services/db/storeLocation.db.ts))
+
+Functions needed:
+
+- `createStoreLocation(storeId, addressId)` - Links store to address
+- `getLocationsByStoreId(storeId)` - Returns StoreLocation[] with Address data
+- `deleteStoreLocation(storeLocationId)` - Unlinks
+- `updateStoreLocation(storeLocationId, newAddressId)` - Changes address
+
+**Test file**: [src/services/db/storeLocation.db.test.ts](src/services/db/storeLocation.db.test.ts)
+
+#### 1.3 Enhance AddressRepository ([src/services/db/address.db.ts](src/services/db/address.db.ts))
+
+Add functions:
+
+- `searchAddressesByText(query)` - For autocomplete
+- `getAddressesByStoreId(storeId)` - Convenience method
+
+**Files to modify**:
+
+- [src/services/db/address.db.ts](src/services/db/address.db.ts)
+- [src/services/db/address.db.test.ts](src/services/db/address.db.test.ts)
+
+---
+
+### Phase 2: TypeScript Types & Validation
+
+#### 2.1 Add Extended Types ([src/types.ts](src/types.ts))
+
+```typescript
+// Store with address data for API responses
+export interface StoreWithLocation {
+  ...Store;
+  locations: Array<{
+    store_location_id: number;
+    address: Address;
+  }>;
+}
+
+// For API requests when creating store
+export interface CreateStoreRequest {
+  name: string;
+  logo_url?: string;
+  address?: {
+    address_line_1: string;
+    city: string;
+    province_state: string;
+    postal_code: string;
+    country?: string;
+  };
+}
+```
+
+#### 2.2 Add Zod Validation Schemas
+
+Create [src/schemas/store.schema.ts](src/schemas/store.schema.ts):
+
+- `createStoreSchema` - Validates POST /stores body
+- `updateStoreSchema` - Validates PUT /stores/:id body
+- `addLocationSchema` - Validates POST /stores/:id/locations body
+
+---
+
+### Phase 3: API Routes
+
+#### 3.1 Create Store Routes ([src/routes/store.routes.ts](src/routes/store.routes.ts))
+
+Endpoints:
+
+- `GET /api/stores` - List all stores (with pagination)
+  - Query params: `?includeLocations=true`, `?search=name`
+- `GET /api/stores/:id` - Get single store with locations
+- `POST /api/stores` - Create store (optionally with address)
+- `PUT /api/stores/:id` - Update store name/logo
+- `DELETE /api/stores/:id` - Delete store (admin only)
+- `POST /api/stores/:id/locations` - Add location to store
+- `DELETE /api/stores/:id/locations/:locationId` - Remove location
+
+**Test file**: [src/routes/store.routes.test.ts](src/routes/store.routes.test.ts)
+
+**Permissions**:
+
+- Create/Update/Delete: Admin only
+- Read: Public (for store listings in flyers/deals)
+
+#### 3.2 Update Existing Routes to Include Address Data
+
+**Files to modify**:
+
+- [src/routes/flyer.routes.ts](src/routes/flyer.routes.ts) - GET /flyers should include store address
+- [src/routes/deals.routes.ts](src/routes/deals.routes.ts) - GET /deals should include store address
+- [src/routes/receipt.routes.ts](src/routes/receipt.routes.ts) - GET /receipts/:id should include store address
+
+---
+
+### Phase 4: Update Database Queries
+
+#### 4.1 Modify Existing Queries to JOIN Addresses
+
+**Files to modify**:
+
+- [src/services/db/admin.db.ts](src/services/db/admin.db.ts)
+  - Line 334: JOIN store_locations and addresses for unmatched items
+  - Line 720: JOIN store_locations and addresses for flyers needing review
+
+- [src/services/db/flyer.db.ts](src/services/db/flyer.db.ts)
+  - Any query that returns flyers with store data
+
+- [src/services/db/deals.db.ts](src/services/db/deals.db.ts)
+  - Add address fields to deal queries
+
+**Pattern to use**:
+
+```sql
+SELECT
+  s.*,
+  json_agg(
+    json_build_object(
+      'store_location_id', sl.store_location_id,
+      'address', row_to_json(a.*)
+    )
+  ) FILTER (WHERE sl.store_location_id IS NOT NULL) as locations
+FROM stores s
+LEFT JOIN store_locations sl ON s.store_id = sl.store_id
+LEFT JOIN addresses a ON sl.address_id = a.address_id
+GROUP BY s.store_id
+```
+
+---
+
+### Phase 5: Frontend Components
+
+#### 5.1 Admin Store Management
+
+Create [src/pages/admin/components/AdminStoreManager.tsx](src/pages/admin/components/AdminStoreManager.tsx):
+
+- Table listing all stores with locations
+- Create store button → opens modal/form
+- Edit store button → opens modal with store+address data
+- Delete store button (with confirmation)
+
+#### 5.2 Store Form Component
+
+Create [src/features/store/StoreForm.tsx](src/features/store/StoreForm.tsx):
+
+- Store name input
+- Logo URL input
+- Address section:
+  - Address line 1 (required)
+  - City (required)
+  - Province/State (required)
+  - Postal code (required)
+  - Country (default: Canada)
+- Reusable for create & edit
+
+#### 5.3 Store Display Components
+
+Create [src/features/store/StoreCard.tsx](src/features/store/StoreCard.tsx):
+
+- Shows store name + logo
+- Shows primary address (if exists)
+- "View all locations" link (if multiple)
+
+Update existing components to use StoreCard:
+
+- Flyer listings
+- Deal listings
+- Receipt displays
+
+#### 5.4 Location Selector Component
+
+Create [src/features/store/LocationSelector.tsx](src/features/store/LocationSelector.tsx):
+
+- Dropdown or map view
+- Filter stores by proximity (future: use lat/long)
+- Used in "Find deals near me" feature
+
+---
+
+### Phase 6: Update Integration Tests
+
+All integration tests that create stores need to use `createStoreWithLocation()`:
+
+**Files to update** (5 files):
+
+1. [src/tests/integration/admin.integration.test.ts](src/tests/integration/admin.integration.test.ts) (line 164)
+2. [src/tests/integration/flyer.integration.test.ts](src/tests/integration/flyer.integration.test.ts) (line 28)
+3. [src/tests/integration/price.integration.test.ts](src/tests/integration/price.integration.test.ts) (line 48)
+4. [src/tests/integration/public.routes.integration.test.ts](src/tests/integration/public.routes.integration.test.ts) (line 66)
+5. [src/tests/integration/receipt.integration.test.ts](src/tests/integration/receipt.integration.test.ts) (line 252)
+
+**Change pattern**:
+
+```typescript
+// OLD:
+const storeResult = await pool.query('INSERT INTO stores (name) VALUES ($1) RETURNING store_id', [
+  'Test Store',
+]);
+
+// NEW:
+import { createStoreWithLocation } from '../utils/storeHelpers';
+const store = await createStoreWithLocation(pool, {
+  name: 'Test Store',
+  address: '123 Test St',
+  city: 'Test City',
+  province: 'ON',
+  postalCode: 'M5V 1A1',
+});
+const storeId = store.storeId;
+```
+
+---
+
+### Phase 7: Update Unit Tests & Mocks
+
+#### 7.1 Update Mock Factories
+
+[src/tests/utils/mockFactories.ts](src/tests/utils/mockFactories.ts) - Add:
+
+- `createMockStore(overrides?): Store`
+- `createMockAddress(overrides?): Address`
+- `createMockStoreLocation(overrides?): StoreLocation`
+- `createMockStoreWithLocation(overrides?): StoreWithLocation`
+
+#### 7.2 Update Component Tests
+
+Files that display stores need updated mocks:
+
+- [src/features/flyer/FlyerDisplay.test.tsx](src/features/flyer/FlyerDisplay.test.tsx)
+- [src/features/flyer/FlyerList.test.tsx](src/features/flyer/FlyerList.test.tsx)
+- Any other components that show store data
+
+---
+
+### Phase 8: Schema Migration (IF NEEDED)
+
+**Check**: Do we need to migrate existing data?
+
+- If production has stores without addresses, we need to handle this
+- Options:
+  1. Make addresses optional (store can exist without location)
+  2. Create "Unknown Location" placeholder addresses
+  3. Manual data entry for existing stores
+
+**Migration file**: [sql/migrations/XXX_add_store_locations_data.sql](sql/migrations/XXX_add_store_locations_data.sql) (if needed)
+

+- Any components displaying store data
+
+**Services (1)**:
+
+- `src/services/cacheService.server.ts` - Add store cache methods
+
+---
+
+## Estimated Complexity
+
+**Low Complexity** (Well-defined, straightforward):
+
+- Phase 1: Database repositories (patterns exist)
+- Phase 2: Type definitions (simple)
+- Phase 6: Update integration tests (mechanical)
+
+**Medium Complexity** (Requires design decisions):
+
+- Phase 3: API routes (standard REST)
+- Phase 4: Update queries (SQL JOINs)
+- Phase 7: Update mocks (depends on types)
+- Phase 9: Cache invalidation (pattern exists)
+
+**High Complexity** (Requires UX design, edge cases):
+
+- Phase 5: Frontend components (UI/UX decisions)
+- Phase 8: Data migration (if needed)
+- Multi-location handling (one store, many addresses)
+
+---
+
+## Dependencies & Risks
+
+**Critical Dependencies**:
+
+1. Address data quality - garbage in, garbage out
+2. Google Maps API integration (future) - for geocoding/validation
+3. Multi-location handling - some stores have 100+ locations
+
+**Risks**:
+
+1. **Breaking changes**: Existing queries might break if address data is required
+2. **Performance**: Joining 3 tables (stores+store_locations+addresses) could be slow
+3. **Data migration**: Existing production stores have no addresses
+4. **Scope creep**: "Find stores near me" leads to mapping features
+
+**Mitigation**:
+
+- Make addresses OPTIONAL initially
+- Add database indexes on foreign keys
+- Use caching aggressively
+- Implement in phases (can stop after Phase 3 and assess)
+
+---
+
+## Questions for Approval
+
+1. **Scope**: Implement all 9 phases, or start with Phase 1-3 (backend only)?
+2. **Addresses required**: Should stores REQUIRE an address, or is it optional?
+3. **Multi-location**: How to handle store chains with many locations?
+   - Option A: One "primary" location
+   - Option B: All locations equal
+   - Option C: User selects location when viewing deals
+4. **Existing data**: How to handle production stores without addresses?
+5. **Priority**: Is this blocking other features, or can it wait?
+6. **Frontend design**: Do we have mockups for store management UI?
+
+---
+
+## Approval Checklist
+
+Before starting implementation, confirm:
+
+- [ ] Plan reviewed and approved by project lead
+- [ ] Scope defined (which phases to implement)
+- [ ] Multi-location strategy decided
+- [ ] Data migration plan approved (if needed)
+- [ ] Frontend design approved (if doing Phase 5)
+- [ ] Testing strategy approved
+- [ ] Estimated timeline acceptable
+
+---
+
+## Next Steps After Approval
+
+1. Create feature branch: `feature/store-address-integration`
+2. Start with Phase 1.1 (StoreRepository)
+3. Write tests first (TDD approach)
+4. Implement phase by phase
+5. Request code review after each phase
+6. Merge only after ALL tests pass

+# Research: Separating E2E Tests from Integration Tests
+
+**Date:** 2026-01-19
+**Status:** In Progress
+**Context:** E2E tests exist with their own config but are not being run separately
+
+## Current State
+
+### Test Structure
+
+- **Unit tests**: `src/tests/unit/` (but most are co-located with source files)
+- **Integration tests**: `src/tests/integration/` (28 test files)
+- **E2E tests**: `src/tests/e2e/` (11 test files) **← NOT CURRENTLY RUNNING**
+
+### Configurations
+
+| Config File                    | Project Name  | Environment | Port | Include Pattern                            |
+| ------------------------------ | ------------- | ----------- | ---- | ------------------------------------------ |
+| `vite.config.ts`               | `unit`        | jsdom       | N/A  | Component/hook tests                       |
+| `vitest.config.integration.ts` | `integration` | node        | 3099 | `src/tests/integration/**/*.test.{ts,tsx}` |
+| `vitest.config.e2e.ts`         | `e2e`         | node        | 3098 | `src/tests/e2e/**/*.e2e.test.ts`           |
+
+### Workspace Configuration
+
+**`vitest.workspace.ts` currently includes:**
+
+```typescript
+export default [
+  'vite.config.ts', // Unit tests
+  'vitest.config.integration.ts', // Integration tests
+  // ❌ vitest.config.e2e.ts is NOT included!
+];
+```
+
+### NPM Scripts
+
+```json
+{
+  "test": "node scripts/check-linux.js && cross-env NODE_ENV=test tsx ./node_modules/vitest/vitest.mjs run",
+  "test:unit": "... --project unit ...",
+  "test:integration": "... --project integration ..."
+  // ❌ NO test:e2e script exists!
+}
+```
+
+### CI/CD Status
+
+**`.gitea/workflows/deploy-to-test.yml` runs:**
+
+- ✅ `npm run test:unit -- --coverage`
+- ✅ `npm run test:integration -- --coverage`
+- ❌ E2E tests are NOT run in CI
+
+## Key Findings
+
+### 1. E2E Tests Are Orphaned
+
+- 11 E2E test files exist but are never executed
+- E2E config file exists (`vitest.config.e2e.ts`) but is not referenced anywhere
+- No npm script to run E2E tests
+- Not included in vitest workspace
+- Not run in CI/CD pipeline
+
+### 2. When Were E2E Tests Created?
+
+Git history shows E2E config was added in commit `e66027d` ("fix e2e and deploy to prod"), but:
+
+- It was never added to the workspace
+- It was never added to CI
+- No test:e2e script was created
+
+This suggests the E2E separation was **started but never completed**.
+
+### 3. How Are Tests Currently Run?
+
+**Locally:**
+
+- `npm test` → runs workspace (unit + integration only)
+- `npm run test:unit` → runs only unit tests
+- `npm run test:integration` → runs only integration tests
+- E2E tests: **Not accessible via any command**
+
+**In CI:**
+
+- Only `test:unit` and `test:integration` are run
+- E2E tests are never executed
+
+### 4. Port Allocation
+
+- Integration tests: Port 3099
+- E2E tests: Port 3098 (configured but never used)
+- No conflicts if both run sequentially
+
+## E2E Test Files (11 total)
+
+1. `admin-authorization.e2e.test.ts`
+2. `admin-dashboard.e2e.test.ts`
+3. `auth.e2e.test.ts`
+4. `budget-journey.e2e.test.ts`
+5. `deals-journey.e2e.test.ts` ← Just fixed URL constraint issue
+6. `error-reporting.e2e.test.ts`
+7. `flyer-upload.e2e.test.ts`
+8. `inventory-journey.e2e.test.ts`
+9. `receipt-journey.e2e.test.ts`
+10. `upc-journey.e2e.test.ts`
+11. `user-journey.e2e.test.ts`
+
+## Problems to Solve
+
+### Immediate Issues
+
+1. **E2E tests are not running** - Code exists but is never executed
+2. **No way to run E2E tests** - No npm script or CI job
+3. **Coverage gaps** - E2E scenarios are untested in practice
+4. **False sense of security** - Team may think E2E tests are running
+
+### Implementation Challenges
+
+#### 1. Adding E2E to Workspace
+
+**Option A: Add to workspace**
+
+```typescript
+// vitest.workspace.ts
+export default [
+  'vite.config.ts',
+  'vitest.config.integration.ts',
+  'vitest.config.e2e.ts', // ← Add this
+];
+```
+
+**Impact:** E2E tests would run with `npm test`, increasing test time significantly
+
+**Option B: Keep separate**
+
+- E2E remains outside workspace
+- Requires explicit `npm run test:e2e` command
+- CI would need separate step for E2E tests
+
+#### 2. Adding NPM Script
+
+```json
+{
+  "test:e2e": "node scripts/check-linux.js && cross-env NODE_ENV=test tsx --max-old-space-size=8192 ./node_modules/vitest/vitest.mjs run --project e2e -c vitest.config.e2e.ts"
+}
+```
+
+**Dependencies:**
+
+- Uses same global setup pattern as integration tests
+- Requires server to be stopped first (like integration tests)
+- Port 3098 must be available
+
+#### 3. CI/CD Integration
+
+**Add to `.gitea/workflows/deploy-to-test.yml`:**
+
+```yaml
+- name: Run E2E Tests
+  run: |
+    npm run test:e2e -- --coverage \
+      --reporter=verbose \
+      --includeTaskLocation \
+      --testTimeout=120000 \
+      --silent=passed-only
+```
+
+**Questions:**
+
+- Should E2E run before or after integration tests?
+- Should E2E failures block deployment?
+- Should E2E have separate coverage reports?
+
+#### 4. Test Organization Questions
+
+- Are current "integration" tests actually E2E tests?
+- Should some E2E tests be moved to integration?
+- What's the distinction between integration and E2E in this project?
+
+#### 5. Coverage Implications
+
+- E2E tests have separate coverage directory: `.coverage/e2e`
+- Integration tests: `.coverage/integration`
+- How to merge coverage from all test types?
+- Do we need combined coverage reports?
+
+## Recommended Approach
+
+### Phase 1: Quick Fix (Enable E2E Tests)
+
+1. ✅ Fix any failing E2E tests (like URL constraints)
+2. Add `test:e2e` npm script
+3. Document how to run E2E tests manually
+4. Do NOT add to workspace yet (keep separate)
+
+### Phase 2: CI Integration
+
+1. Add E2E test step to `.gitea/workflows/deploy-to-test.yml`
+2. Run after integration tests pass
+3. Allow failures initially (monitor results)
+4. Make blocking once stable
+
+### Phase 3: Optimize
+
+1. Review test categorization (integration vs E2E)
+2. Consider adding to workspace if test time is acceptable
+3. Merge coverage reports if needed
+4. Document test strategy in testing docs
+
+## Next Steps
+
+1. **Create `test:e2e` script** in package.json
+2. **Run E2E tests manually** to verify they work
+3. **Fix any failing E2E tests**
+4. **Document E2E testing** in TESTING.md
+5. **Add to CI** once stable
+6. **Consider workspace integration** after CI is stable
+
+## Questions for Team
+
+1. Why were E2E tests never fully integrated?
+2. Should E2E tests run on every commit or separately?
+3. What's the acceptable test time for local development?
+4. Should we run E2E tests in parallel or sequentially with integration?

+**Status**: ✅ **ALL 4 CRITICAL TASKS COMPLETE**
+
+---
+
+## Executive Summary
+
+Successfully implemented all 4 critical UI/UX improvements identified in the design audit. The application now has:
+
+- ✅ Defined brand colors with comprehensive documentation
+- ✅ Reusable Button component with 27 passing tests
+- ✅ Interactive onboarding tour for first-time users
+- ✅ Mobile-first navigation with bottom tab bar
+
+**Total Implementation Time**: ~4 hours

+**Lines of Code Added**: ~1,200 lines
+**Tests Written**: 27 comprehensive unit tests
+
+---
+
+## Task 1: Brand Colors ✅
+
+### Problem
+
+Classes like `text-brand-primary`, `bg-brand-secondary` were used 30+ times but never defined in Tailwind config, causing broken styling.
+
+### Solution
+
+Defined a cohesive teal-based color palette in `tailwind.config.js`:
+
+| Token                 | Value                | Usage                   |
+| --------------------- | -------------------- | ----------------------- |
+| `brand-primary`       | `#0d9488` (teal-600) | Main brand color, icons |
+| `brand-secondary`     | `#14b8a6` (teal-500) | Primary action buttons  |
+| `brand-light`         | `#ccfbf1` (teal-100) | Light backgrounds       |
+| `brand-dark`          | `#115e59` (teal-800) | Hover states, dark mode |
+| `brand-primary-light` | `#99f6e4` (teal-200) | Subtle accents          |
+| `brand-primary-dark`  | `#134e4a` (teal-900) | Deep backgrounds        |
+
+### Deliverables
+
+- **Modified**: `tailwind.config.js`
+- **Created**: `docs/DESIGN_TOKENS.md` (300+ lines)
+  - Complete color palette documentation
+  - Usage guidelines with code examples
+  - WCAG 2.1 Level AA accessibility compliance table
+  - Dark mode mappings
+  - Color blindness considerations
+
+### Impact
+
+- Fixed 30+ broken class references instantly
+- Established consistent visual identity
+- All colors meet WCAG AA contrast ratios
+
+---
+
+## Task 2: Shared Button Component ✅
+
+### Problem
+
+Button styles duplicated across 20+ components with inconsistent patterns, no shared component.
+
+### Solution
+
+Created fully-featured Button component with TypeScript types:
+
+**Variants**:
+
+- `primary` - Brand-colored call-to-action buttons
+- `secondary` - Gray supporting action buttons
+- `danger` - Red destructive action buttons
+- `ghost` - Transparent minimal buttons
+
+**Features**:
+
+- 3 sizes: `sm`, `md`, `lg`
+- Loading state with built-in spinner
+- Left/right icon support
+- Full width option
+- Disabled state handling
+- Dark mode support for all variants
+- WCAG 2.5.5 compliant touch targets
+
+### Deliverables
+
+- **Created**: `src/components/Button.tsx` (80 lines)
+- **Created**: `src/components/Button.test.tsx` (27 tests, all passing)
+- **Modified**: Integrated into 3 major features:
+  - `src/features/flyer/FlyerUploader.tsx` (2 buttons)
+  - `src/features/shopping/WatchedItemsList.tsx` (1 button)
+  - `src/features/shopping/ShoppingList.tsx` (3 buttons)
+
+### Test Results
+
+```
+✓ Button component (27)
+  ✓ renders with primary variant
+  ✓ renders with secondary variant
+  ✓ renders with danger variant
+  ✓ renders with ghost variant
+  ✓ renders with small size
+  ✓ renders with medium size (default)
+  ✓ renders with large size
+  ✓ shows loading spinner when isLoading is true
+  ✓ disables button when isLoading is true
+  ✓ does not call onClick when disabled
+  ✓ renders with left icon
+  ✓ renders with right icon
+  ✓ renders with both icons
+  ✓ renders full width
+  ✓ merges custom className
+  ✓ passes through HTML attributes
+  ... (27 total)
+```
+
+### Impact
+
+- Reduced code duplication by ~150 lines
+- Consistent button styling across app
+- Easier to maintain and update button styles globally
+- Loading states handled automatically
+
+---
+
+## Task 3: Onboarding Tour ✅
+
+### Problem
+
+New users saw "Welcome to Flyer Crawler!" with no explanation of features or how to get started.
+
+### Solution
+
+Implemented interactive guided tour using `driver.js` (framework-agnostic, React 19 compatible):
+
+**Tour Steps** (6 total):
+
+1. **Flyer Uploader** - "Upload grocery flyers here..."
+2. **Extracted Data** - "View AI-extracted items..."
+3. **Watch Button** - "Click + Watch to track items..."
+4. **Watched Items** - "Your watchlist appears here..."
+5. **Price Chart** - "See active deals on watched items..."
+6. **Shopping List** - "Create shopping lists..."
+
+**Features**:
+
+- Auto-starts for first-time users (500ms delay for DOM readiness)
+- Persists completion in localStorage (`flyer_crawler_onboarding_completed`)
+- Skip button for experienced users
+- Progress indicator showing current step
+- Custom styled with pastel colors, sharp borders (design system)
+- Dark mode compatible
+- Zero React peer dependencies (compatible with React 19)
+
+### Deliverables
+
+- **Created**: `src/hooks/useOnboardingTour.ts` (custom hook with Driver.js)
+- **Modified**: Added `data-tour` attributes to 6 components:
+  - `src/features/flyer/FlyerUploader.tsx`
+  - `src/features/flyer/ExtractedDataTable.tsx`
+  - `src/features/shopping/WatchedItemsList.tsx`
+  - `src/features/charts/PriceChart.tsx`
+  - `src/features/shopping/ShoppingList.tsx`
+- **Modified**: `src/layouts/MainLayout.tsx` - Integrated tour via hook
+- **Installed**: `driver.js@^1.3.1`
+
+**Migration Note (2026-01-21)**: Originally implemented with `react-joyride@2.9.3`, but migrated to `driver.js` for React 19 compatibility.
+
+### User Flow
+
+1. New user visits app → Tour starts automatically
+2. User sees 6 contextual tooltips guiding through features
+3. User can skip tour or complete all steps
+4. Completion saved to localStorage
+5. Tour never shows again unless localStorage is cleared
+
+### Impact
+
+- Improved onboarding experience for new users
+- Reduced confusion about key features
+- Lower barrier to entry for first-time users
+
+---
+
+## Task 4: Mobile Navigation ✅
+
+### Problem
+
+Mobile users faced excessive scrolling with 7 stacked widgets in sidebar. Desktop layout forced onto mobile screens.
+
+### Solution
+
+Implemented mobile-first responsive navigation with bottom tab bar.
+
+### 4.1 MobileTabBar Component
+
+**Created**: `src/components/MobileTabBar.tsx`
+
+**Features**:
+
+- Fixed bottom navigation (z-40)
+- 4 tabs with icons and labels:
+  - **Home** (DocumentTextIcon) → `/`
+  - **Deals** (TagIcon) → `/deals`
+  - **Lists** (ListBulletIcon) → `/lists`
+  - **Profile** (UserIcon) → `/profile`
+- Active tab highlighting with brand-primary
+- 44x44px touch targets (WCAG 2.5.5 compliant)
+- Hidden on desktop (`lg:hidden`)
+- Hidden on admin routes
+- Dark mode support
+
+### 4.2 New Page Components
+
+**Created 3 new route pages**:
+
+1. **DealsPage** (`src/pages/DealsPage.tsx`):
+   - Renders: WatchedItemsList + PriceChart + PriceHistoryChart
+   - Integrated with `useWatchedItems`, `useShoppingLists` hooks
+   - Dedicated page for viewing active deals
+
+2. **ShoppingListsPage** (`src/pages/ShoppingListsPage.tsx`):
+   - Renders: ShoppingList component
+   - Full CRUD operations for shopping lists
+   - Integrated with `useShoppingLists` hook
+
+3. **FlyersPage** (`src/pages/FlyersPage.tsx`):
+   - Renders: FlyerList + FlyerUploader
+   - Standalone flyer management page
+   - Uses `useFlyerSelection` hook
+
+### 4.3 MainLayout Responsive Updates
+
+**Modified**: `src/layouts/MainLayout.tsx`
+
+**Changes**:
+
+- Left sidebar: Added `hidden lg:block` (hides on mobile)
+- Right sidebar: Added `hidden lg:block` (hides on mobile)
+- Main content: Added `pb-16 lg:pb-0` (bottom padding for tab bar)
+- Desktop layout unchanged (3-column grid ≥1024px)
+
+### 4.4 App Routing
+
+**Modified**: `src/App.tsx`
+
+**Added Routes**:
+
+```tsx
+<Route path="/deals" element={<DealsPage />} />
+<Route path="/lists" element={<ShoppingListsPage />} />
+<Route path="/flyers" element={<FlyersPage />} />
+<Route path="/profile" element={<UserProfilePage />} />
+```
+
+**Added Component**: `<MobileTabBar />` (conditionally rendered)
+
+### Responsive Breakpoints
+
+| Screen Size              | Layout Behavior                                 |
+| ------------------------ | ----------------------------------------------- |
+| < 1024px (mobile/tablet) | Tab bar visible, sidebars hidden, single-column |
+| ≥ 1024px (desktop)       | Tab bar hidden, sidebars visible, 3-column grid |
+
+### Impact
+
+- Eliminated excessive scrolling on mobile devices
+- Improved discoverability of key features (Deals, Lists)
+- Desktop experience completely unchanged
+- Better mobile user experience (bottom thumb zone)
+- Each feature accessible in 1 tap
+
+---
+
+## Accessibility Compliance
+
+### WCAG 2.1 Level AA Standards Met
+
+| Criterion                    | Status  | Implementation                    |
+| ---------------------------- | ------- | --------------------------------- |
+| **1.4.3 Contrast (Minimum)** | ✅ Pass | All brand colors meet 4.5:1 ratio |
+| **2.5.5 Target Size**        | ✅ Pass | Tab bar buttons are 44x44px       |
+| **2.4.7 Focus Visible**      | ✅ Pass | All buttons have focus rings      |
+| **1.4.13 Content on Hover**  | ✅ Pass | Tour tooltips dismissable         |
+| **4.1.2 Name, Role, Value**  | ✅ Pass | Semantic HTML, ARIA labels        |
+
+### Color Blindness Testing
+
+- Teal palette accessible for deuteranopia, protanopia, tritanopia
+- Never relying on color alone (always paired with text/icons)
+
+---
+
+## Testing Summary
+
+### Type-Check Results
+
+```bash
+npm run type-check
+```
+
+- ✅ All new files pass TypeScript compilation
+- ✅ No errors in new code
+- ℹ️ 156 pre-existing test file errors (unrelated to changes)

+```bash
+npm test -- --run src/components/Button.test.tsx
+```
+
+- ✅ 27/27 Button component tests passing
+- ✅ All existing integration tests still passing (48 tests)
+- ✅ No test regressions
+
+### Manual Testing Required
+
+**Onboarding Tour**:
+
+1. Open browser DevTools → Application → Local Storage
+2. Delete key: `flyer_crawler_onboarding_completed`

+   - **375px** (iPhone SE) - Tab bar visible, sidebar hidden
+   - **768px** (iPad) - Tab bar visible, sidebar hidden
+   - **1024px** (Desktop) - Tab bar hidden, sidebar visible
+4. Click each tab:
+   - Home → Shows flyer view
+   - Deals → Shows watchlist + price chart
+   - Lists → Shows shopping lists
+   - Profile → Shows user profile
+5. Verify active tab highlighted in brand-primary
+6. Test dark mode toggle

+## Error Handling
+
+**ADR**: [ADR-001](../adr/0001-standardized-error-handling-for-database-operations.md)
+
+### Repository Layer Error Handling
+
+```typescript
+import { handleDbError, NotFoundError } from '../services/db/errors.db';
+import { PoolClient } from 'pg';
+
+export async function getFlyerById(id: number, client?: PoolClient): Promise<Flyer> {
+  const db = client || pool;
+
+  try {
+    const result = await db.query('SELECT * FROM flyers WHERE id = $1', [id]);
+
+    if (result.rows.length === 0) {
+      throw new NotFoundError('Flyer', id);
+    }
+
+    return result.rows[0];
+  } catch (error) {
+    throw handleDbError(error);
+  }
+}
+```
+
+### Route Layer Error Handling
+
+```typescript
+import { sendError } from '../utils/apiResponse';
+
+app.get('/api/flyers/:id', async (req, res) => {
+  try {
+    const flyer = await flyerDb.getFlyerById(parseInt(req.params.id));
+    return sendSuccess(res, flyer);
+  } catch (error) {
+    return sendError(res, error);
+  }
+});
+```
+
+### Custom Error Types
+
+```typescript
+// NotFoundError - Entity not found
+throw new NotFoundError('Flyer', id);
+
+// ValidationError - Invalid input
+throw new ValidationError('Invalid email format');
+
+// DatabaseError - Database operation failed
+throw new DatabaseError('Failed to insert flyer', originalError);
+```
+

+
+## Repository Patterns
+
+**ADR**: [ADR-034](../adr/0034-repository-layer-method-naming-conventions.md)
+
+### Method Naming Conventions
+
+| Prefix  | Returns        | Not Found Behavior   | Use Case                  |
+| ------- | -------------- | -------------------- | ------------------------- |
+| `get*`  | Entity         | Throws NotFoundError | When entity must exist    |
+| `find*` | Entity \| null | Returns null         | When entity may not exist |
+| `list*` | Array          | Returns []           | When returning multiple   |
+
+### Get Method (Must Exist)
+
+```typescript
+/**
+ * Get a flyer by ID. Throws NotFoundError if not found.
+ */
+export async function getFlyerById(id: number, client?: PoolClient): Promise<Flyer> {
+  const db = client || pool;
+
+  try {
+    const result = await db.query('SELECT * FROM flyers WHERE id = $1', [id]);
+
+    if (result.rows.length === 0) {
+      throw new NotFoundError('Flyer', id);
+    }
+
+    return result.rows[0];
+  } catch (error) {
+    throw handleDbError(error);
+  }
+}
+```
+
+### Find Method (May Not Exist)
+
+```typescript
+/**
+ * Find a flyer by ID. Returns null if not found.
+ */
+export async function findFlyerById(id: number, client?: PoolClient): Promise<Flyer | null> {
+  const db = client || pool;
+
+  try {
+    const result = await db.query('SELECT * FROM flyers WHERE id = $1', [id]);
+
+    return result.rows[0] || null;
+  } catch (error) {
+    throw handleDbError(error);
+  }
+}
+```
+
+### List Method (Multiple Results)
+
+```typescript
+/**
+ * List all active flyers. Returns empty array if none found.
+ */
+export async function listActiveFlyers(client?: PoolClient): Promise<Flyer[]> {
+  const db = client || pool;
+
+  try {
+    const result = await db.query(
+      'SELECT * FROM flyers WHERE end_date >= CURRENT_DATE ORDER BY start_date DESC',
+    );
+
+    return result.rows;
+  } catch (error) {
+    throw handleDbError(error);
+  }
+}
+```
+

+
+## API Response Patterns
+
+**ADR**: [ADR-028](../adr/0028-consistent-api-response-format.md)
+
+### Success Response
+
+```typescript
+import { sendSuccess } from '../utils/apiResponse';
+
+app.post('/api/flyers', async (req, res) => {
+  const flyer = await flyerService.createFlyer(req.body);

+
+## Transaction Management
+
+**ADR**: [ADR-002](../adr/0002-transaction-management-pattern.md)
+
+### Basic Transaction
+
+```typescript
+import { withTransaction } from '../services/db/transaction.db';
+
+export async function createFlyerWithItems(
+  flyerData: FlyerInput,
+  items: FlyerItemInput[],
+): Promise<Flyer> {
+  return withTransaction(async (client) => {

+
+    // Automatically commits on success, rolls back on error
+    return { ...flyer, items: createdItems };
+  });
+}
+```
+
+### Nested Transactions
+
+```typescript

+
+## Quick Debugging Checklist
+
+When something breaks, check these first:
+
+1. **Are containers running?**
+
+   ```bash
+   podman ps
+   ```
+
+2. **Is the database accessible?**
+
+   ```bash
+   podman exec flyer-crawler-postgres pg_isready -U postgres
+   ```
+
+3. **Are environment variables set?**
+
+   ```bash
+   # Check .env.local exists
+   cat .env.local
+   ```
+
+4. **Are there recent errors in logs?**
+
+   ```bash
+   # PM2 logs (dev container)
+   podman exec -it flyer-crawler-dev pm2 logs
+
+   # Container logs
+   podman logs -f flyer-crawler-dev
+
+   # PM2 logs (production)
+   pm2 logs flyer-crawler-api
+   ```
+
+5. **Are PM2 processes running?**
+
+   ```bash
+   podman exec -it flyer-crawler-dev pm2 status
+   ```
+
+6. **Is Redis accessible?**
+
+   ```bash
+   podman exec flyer-crawler-redis redis-cli ping
+   ```
+
+---
+
+## Container Issues
+
+### Container Won't Start
+
+**Symptom**: `podman start` fails or container exits immediately
+
+**Debug**:
+
+```bash
+# Check container status
+podman ps -a
+
+# View container logs
+podman logs flyer-crawler-postgres
+podman logs flyer-crawler-redis
+podman logs flyer-crawler-dev
+
+# Inspect container
+podman inspect flyer-crawler-dev
+```
+
+**Common Causes**:
+
+- Port already in use
+- Insufficient resources
+- Configuration error
+
+**Solutions**:
+
+```bash
+# Check port usage
+netstat -an | findstr "5432"
+netstat -an | findstr "6379"
+
+# Remove and recreate container
+podman stop flyer-crawler-postgres
+podman rm flyer-crawler-postgres
+# ... recreate with podman run ...
+```
+
+### "Unable to connect to Podman socket"
+
+**Symptom**: `Error: unable to connect to Podman socket`
+
+**Solution**:
+
+```bash
+# Start Podman machine
+podman machine start
+
+# Verify it's running
+podman machine list
+```
+
+### Port Already in Use
+
+**Symptom**: `Error: port 5432 is already allocated`
+
+**Solutions**:
+
+**Option 1**: Stop conflicting service
+
+```bash
+# Find process using port
+netstat -ano | findstr "5432"
+
+# Stop the service or kill process
+```
+
+**Option 2**: Use different port
+
+```bash
+# Run container on different host port
+podman run -d --name flyer-crawler-postgres -p 5433:5432 ...
+
+# Update .env.local
+DB_PORT=5433
+```
+
+---
+
+## Database Issues
+
+### Connection Refused
+
+**Symptom**: `Error: connect ECONNREFUSED 127.0.0.1:5432`
+
+**Debug**:
+
+```bash
+# 1. Check if PostgreSQL container is running
+podman ps | grep postgres
+
+# 2. Check if PostgreSQL is ready
+podman exec flyer-crawler-postgres pg_isready -U postgres
+
+# 3. Test connection
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "SELECT 1;"
+```
+
+**Common Causes**:
+
+- Container not running
+- PostgreSQL still initializing
+- Wrong credentials in `.env.local`
+
+**Solutions**:
+
+```bash
+# Start container
+podman start flyer-crawler-postgres
+
+# Wait for initialization (check logs)
+podman logs -f flyer-crawler-postgres
+
+# Verify credentials match .env.local
+cat .env.local | grep DB_
+```
+
+### Schema Out of Sync
+
+**Symptom**: Tests fail with missing column or table errors
+
+**Cause**: `master_schema_rollup.sql` not in sync with migrations
+
+**Solution**:
+
+```bash
+# Reset database with current schema
+podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/drop_tables.sql
+podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/master_schema_rollup.sql
+
+# Verify schema
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "\dt"
+```
+
+### Query Performance Issues
+
+**Debug**:
+
+```sql
+-- Enable query logging
+ALTER DATABASE flyer_crawler_dev SET log_statement = 'all';
+
+-- Check slow queries
+SELECT query, mean_exec_time, calls
+FROM pg_stat_statements
+WHERE mean_exec_time > 100
+ORDER BY mean_exec_time DESC
+LIMIT 10;
+
+-- Analyze query plan
+EXPLAIN ANALYZE
+SELECT * FROM flyers WHERE store_id = 1;
+```
+
+**Solutions**:
+
+- Add missing indexes
+- Optimize WHERE clauses
+- Use connection pooling
+- See [ADR-034](../adr/0034-repository-layer-method-naming-conventions.md)
+
+---
+
+## Test Failures
+
+### Tests Pass on Windows, Fail in Container
+
+**Cause**: Platform-specific behavior (ADR-014)
+
+**Rule**: Container results are authoritative. Windows results are unreliable.
+
+**Solution**:
+
+```bash
+# Always run tests in container
+podman exec -it flyer-crawler-dev npm test
+
+# For specific test
+podman exec -it flyer-crawler-dev npm test -- --run src/path/to/test.test.ts
+```
+
+### Integration Tests Fail
+
+**Common Issues**:
+
+**1. Vitest globalSetup Context Isolation**
+
+**Symptom**: Mocks or spies don't work in integration tests
+
+**Cause**: `globalSetup` runs in separate Node.js context
+
+**Solutions**:
+
+- Mark test as `.todo()` and document limitation
+- Create test-only API endpoints
+- Use Redis-based mock flags
+
+See [CLAUDE.md#integration-test-issues](../../CLAUDE.md#integration-test-issues) for details.
+
+**2. Cache Stale After Direct SQL**
+
+**Symptom**: Test reads stale data after direct database insert
+
+**Cause**: Cache not invalidated
+
+**Solution**:
+
+```typescript
+// After direct SQL insert
+await cacheService.invalidateFlyers();
+```
+
+**3. Queue Interference**
+
+**Symptom**: Cleanup worker processes test data before assertions
+
+**Solution**:
+
+```typescript
+const { cleanupQueue } = await import('../../services/queues.server');
+await cleanupQueue.drain();
+await cleanupQueue.pause();
+// ... test ...
+await cleanupQueue.resume();
+```
+
+### Type Check Failures
+
+**Symptom**: `npm run type-check` fails
+
+**Debug**:
+
+```bash
+# Run type check in container
+podman exec -it flyer-crawler-dev npm run type-check
+
+# Check specific file
+podman exec -it flyer-crawler-dev npx tsc --noEmit src/path/to/file.ts
+```
+
+**Common Causes**:
+
+- Missing type definitions
+- Incorrect imports
+- Type mismatch in function calls
+
+---
+
+## API Errors
+
+### 404 Not Found
+
+**Debug**:
+
+```bash
+# Check route registration
+grep -r "router.get" src/routes/
+
+# Check route path matches request
+# Verify middleware order
+```
+
+**Common Causes**:
+
+- Route not registered in `server.ts`
+- Typo in route path
+- Middleware blocking request
+
+### 500 Internal Server Error
+
+**Debug**:
+
+```bash
+# Check application logs
+podman logs -f flyer-crawler-dev
+
+# Check Bugsink for errors
+# Visit: http://localhost:8443 (dev) or https://bugsink.projectium.com (prod)
+```
+
+**Common Causes**:
+
+- Unhandled exception
+- Database error
+- Missing environment variable
+
+**Solution Pattern**:
+
+```typescript
+// Always wrap route handlers
+app.get('/api/endpoint', async (req, res) => {
+  try {
+    const result = await service.doSomething();
+    return sendSuccess(res, result);
+  } catch (error) {
+    return sendError(res, error); // Handles error types automatically
+  }
+});
+```
+
+### 401 Unauthorized
+
+**Debug**:
+
+```bash
+# Check JWT token in request
+# Verify token is valid and not expired
+
+# Test token decoding
+node -e "console.log(require('jsonwebtoken').decode('YOUR_TOKEN_HERE'))"
+```
+
+**Common Causes**:
+
+- Token expired
+- Invalid token format
+- Missing Authorization header
+- Wrong JWT_SECRET
+
+---
+
+## Authentication Problems
+
+### OAuth Not Working
+
+**Debug**:
+
+```bash
+# 1. Verify OAuth credentials
+cat .env.local | grep GOOGLE_CLIENT
+
+# 2. Check OAuth routes are registered
+grep -r "passport.authenticate" src/routes/
+
+# 3. Verify redirect URI matches Google Console
+# Should be: http://localhost:3001/api/auth/google/callback
+```
+
+**Common Issues**:
+
+- Redirect URI mismatch in Google Console
+- OAuth not enabled (commented out in config)
+- Wrong client ID/secret
+
+See [AUTHENTICATION.md](../architecture/AUTHENTICATION.md) for setup.
+
+### JWT Token Invalid
+
+**Debug**:
+
+```typescript
+// Decode token to inspect
+import jwt from 'jsonwebtoken';
+
+const decoded = jwt.decode(token);
+console.log('Token payload:', decoded);
+console.log('Expired:', decoded.exp < Date.now() / 1000);
+```
+
+**Solutions**:
+
+- Regenerate token
+- Check JWT_SECRET matches between environments
+- Verify token hasn't expired
+
+---
+
+## PM2 Process Issues (Dev Container)
+
+### PM2 Process Not Starting
+
+**Symptom**: `pm2 status` shows process as "errored" or "stopped"
+
+**Debug**:
+
+```bash
+# Check process status
+podman exec -it flyer-crawler-dev pm2 status
+
+# View process logs
+podman exec -it flyer-crawler-dev pm2 logs flyer-crawler-api-dev --lines 50
+
+# Show detailed process info
+podman exec -it flyer-crawler-dev pm2 show flyer-crawler-api-dev
+
+# Check if port is in use
+podman exec -it flyer-crawler-dev netstat -tlnp | grep 3001
+```
+
+**Common Causes**:
+
+- Port already in use by another process
+- Missing environment variables
+- Syntax error in code
+- Database connection failure
+
+**Solutions**:
+
+```bash
+# Restart specific process
+podman exec -it flyer-crawler-dev pm2 restart flyer-crawler-api-dev
+
+# Restart all processes
+podman exec -it flyer-crawler-dev pm2 restart all
+
+# Delete and recreate processes
+podman exec -it flyer-crawler-dev pm2 delete all
+podman exec -it flyer-crawler-dev pm2 start /app/ecosystem.dev.config.cjs
+```
+
+### PM2 Log Access
+
+**View logs in real-time**:
+
+```bash
+# All processes
+podman exec -it flyer-crawler-dev pm2 logs
+
+# Specific process
+podman exec -it flyer-crawler-dev pm2 logs flyer-crawler-api-dev
+
+# Last 100 lines
+podman exec -it flyer-crawler-dev pm2 logs --lines 100
+```
+
+**View log files directly**:
+
+```bash
+# API logs
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-dev cat /var/log/pm2/api-out.log
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-dev cat /var/log/pm2/api-error.log
+
+# Worker logs
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-dev cat /var/log/pm2/worker-out.log
+
+# Vite logs
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-dev cat /var/log/pm2/vite-out.log
+```
+
+### Redis Log Access
+
+**View Redis logs**:
+
+```bash
+# View Redis log file
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-redis cat /var/log/redis/redis-server.log
+
+# View from dev container (shared volume)
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-dev cat /var/log/redis/redis-server.log
+```
+
+---
+
+## Background Job Issues
+
+### Jobs Not Processing
+
+**Debug**:
+
+```bash
+# Check if worker is running (dev container)
+podman exec -it flyer-crawler-dev pm2 status
+
+# Check worker logs (dev container)
+podman exec -it flyer-crawler-dev pm2 logs flyer-crawler-worker-dev
+
+# Check if worker is running (production)
+pm2 list
+
+# Check worker logs (production)
+pm2 logs flyer-crawler-worker
+
+# Check Redis connection
+podman exec flyer-crawler-redis redis-cli ping
+
+# Check queue status
+node -e "
+const { flyerProcessingQueue } = require('./dist/services/queues.server.js');
+flyerProcessingQueue.getJobCounts().then(console.log);
+"
+```
+
+**Common Causes**:
+
+- Worker not running
+- Redis connection lost
+- Queue paused
+- Job stuck in failed state
+
+**Solutions**:
+
+```bash
+# Restart worker
+pm2 restart flyer-crawler-worker
+
+# Clear failed jobs
+node -e "
+const { flyerProcessingQueue } = require('./dist/services/queues.server.js');
+flyerProcessingQueue.clean(0, 1000, 'failed');
+"
+```
+
+### Jobs Failing
+
+**Debug**:
+
+```bash
+# Check failed jobs
+node -e "
+const { flyerProcessingQueue } = require('./dist/services/queues.server.js');
+flyerProcessingQueue.getFailed().then(jobs => {
+  jobs.forEach(job => console.log(job.failedReason));
+});
+"
+
+# Check worker logs for stack traces
+pm2 logs flyer-crawler-worker --lines 100
+```
+
+**Common Causes**:
+
+- Gemini API errors
+- Database errors
+- Invalid job data
+
+---
+
+## SSL Certificate Issues
+
+### Images Not Loading (ERR_CERT_AUTHORITY_INVALID)
+
+**Symptom**: Flyer images fail to load with `ERR_CERT_AUTHORITY_INVALID` in browser console
+
+**Cause**: Mixed hostname origins - user accesses via `localhost` but images use `127.0.0.1` (or vice versa)
+
+**Debug**:
+
+```bash
+# Check which hostname images are using
+podman exec flyer-crawler-dev psql -U postgres -d flyer_crawler_dev \
+  -c "SELECT image_url FROM flyers LIMIT 1;"
+
+# Verify certificate includes both hostnames
+podman exec flyer-crawler-dev openssl x509 -in /app/certs/localhost.crt -text -noout | grep -A1 "Subject Alternative Name"
+
+# Check NGINX accepts both hostnames
+podman exec flyer-crawler-dev grep "server_name" /etc/nginx/sites-available/default
+```
+
+**Solution**: The dev container is configured to handle both hostnames:
+
+1. Certificate includes SANs for `localhost`, `127.0.0.1`, and `::1`
+2. NGINX `server_name` directive includes both `localhost` and `127.0.0.1`
+
+If you still see errors:
+
+```bash
+# Rebuild container to regenerate certificate
+podman-compose down
+podman-compose build --no-cache flyer-crawler-dev
+podman-compose up -d
+```
+
+See [FLYER-URL-CONFIGURATION.md](../FLYER-URL-CONFIGURATION.md#ssl-certificate-configuration-dev-container) for full details.
+
+### Self-Signed Certificate Not Trusted
+
+**Symptom**: Browser shows security warning for `https://localhost`
+
+**Temporary Workaround**: Accept the warning by clicking "Advanced" > "Proceed to localhost"
+
+**Permanent Fix (Recommended)**: Install the mkcert CA certificate to eliminate all SSL warnings.
+
+The CA certificate is located at `certs/mkcert-ca.crt` in the project root. See [`certs/README.md`](../../certs/README.md) for platform-specific installation instructions (Windows, macOS, Linux, Firefox).
+
+After installation:
+
+- Your browser will trust all mkcert certificates without warnings
+- Both `https://localhost/` and `https://127.0.0.1/` will work without SSL errors
+- Flyer images will load without `ERR_CERT_AUTHORITY_INVALID` errors
+
+### NGINX SSL Configuration Test
+
+**Debug**:
+
+```bash
+# Test NGINX configuration
+podman exec flyer-crawler-dev nginx -t
+
+# Check if NGINX is listening on 443
+podman exec flyer-crawler-dev netstat -tlnp | grep 443
+
+# Verify certificate files exist
+podman exec flyer-crawler-dev ls -la /app/certs/
+```
+
+---
+
+## Frontend Issues
+
+### Hot Reload Not Working
+
+**Debug**:
+
+```bash
+# Check Vite is running
+curl http://localhost:5173
+
+# Check for port conflicts
+netstat -an | findstr "5173"
+```
+
+**Solution**:
+
+```bash
+# Restart dev server
+npm run dev
+```
+
+### API Calls Failing (CORS)
+
+**Symptom**: `CORS policy: No 'Access-Control-Allow-Origin' header`
+
+**Debug**:
+
+```typescript
+// Check CORS configuration in server.ts
+import cors from 'cors';
+
+app.use(
+  cors({
+    origin: env.FRONTEND_URL, // Should match http://localhost:5173 in dev
+    credentials: true,
+  }),
+);
+```
+
+**Solution**: Verify `FRONTEND_URL` in `.env.local` matches the frontend URL
+
+---
+
+## Performance Problems
+
+### Slow API Responses
+
+**Debug**:
+
+```typescript
+// Add timing logs
+const start = Date.now();
+const result = await slowOperation();
+console.log(`Operation took ${Date.now() - start}ms`);
+```
+
+**Common Causes**:
+
+- N+1 query problem
+- Missing database indexes
+- Large payload size
+- No caching
+
+**Solutions**:
+
+- Use JOINs instead of multiple queries
+- Add indexes: `CREATE INDEX idx_name ON table(column);`
+- Implement pagination
+- Add Redis caching
+
+### High Memory Usage
+
+**Debug**:
+
+```bash
+# Check PM2 memory usage
+pm2 monit
+
+# Check container memory
+podman stats flyer-crawler-dev
+```
+
+**Common Causes**:
+
+- Memory leak
+- Large in-memory cache
+- Unbounded array growth
+
+---
+
+## Debugging Tools
+
+### VS Code Debugger
+
+**Launch Configuration** (`.vscode/launch.json`):
+
+```json
+{
+  "version": "0.2.0",
+  "configurations": [
+    {
+      "type": "node",
+      "request": "launch",
+      "name": "Debug Tests",
+      "program": "${workspaceFolder}/node_modules/vitest/vitest.mjs",
+      "args": ["--run", "${file}"],
+      "console": "integratedTerminal",
+      "internalConsoleOptions": "neverOpen"
+    }
+  ]
+}
+```
+
+### Logging
+
+```typescript
+import { logger } from './utils/logger';
+
+// Structured logging
+logger.info('Processing flyer', { flyerId, userId });
+logger.error('Failed to process', { error, context });
+logger.debug('Cache hit', { key, ttl });
+```
+
+### Database Query Logging
+
+```typescript
+// In development, log all queries
+if (env.NODE_ENV === 'development') {
+  pool.on('connect', () => {
+    console.log('Database connected');
+  });
+
+  // Log slow queries
+  const originalQuery = pool.query.bind(pool);
+  pool.query = async (...args) => {
+    const start = Date.now();
+    const result = await originalQuery(...args);
+    const duration = Date.now() - start;
+    if (duration > 100) {
+      console.log(`Slow query (${duration}ms):`, args[0]);
+    }
+    return result;
+  };
+}
+```
+
+### Redis Debugging
+
+```bash
+# Monitor Redis commands
+podman exec -it flyer-crawler-redis redis-cli monitor
+
+# Check keys
+podman exec flyer-crawler-redis redis-cli keys "*"
+
+# Get key value
+podman exec flyer-crawler-redis redis-cli get "flyer:123"
+
+# Check cache stats
+podman exec flyer-crawler-redis redis-cli info stats
+```

+# Design Tokens
+
+This document defines the design tokens used throughout the Flyer Crawler application, including color palettes, usage guidelines, and semantic mappings.
+
+## Color Palette
+
+### Brand Colors
+
+The Flyer Crawler brand uses a **teal** color palette that evokes freshness, value, and the grocery shopping experience.
+
+| Token                 | Value     | Tailwind | RGB           | Usage                                    |
+| --------------------- | --------- | -------- | ------------- | ---------------------------------------- |
+| `brand-primary`       | `#0d9488` | teal-600 | 13, 148, 136  | Main brand color, primary call-to-action |
+| `brand-secondary`     | `#14b8a6` | teal-500 | 20, 184, 166  | Supporting actions, primary buttons      |
+| `brand-light`         | `#ccfbf1` | teal-100 | 204, 251, 241 | Backgrounds, highlights (light mode)     |
+| `brand-dark`          | `#115e59` | teal-800 | 17, 94, 89    | Hover states, backgrounds (dark mode)    |
+| `brand-primary-light` | `#99f6e4` | teal-200 | 153, 246, 228 | Subtle backgrounds, light accents        |
+| `brand-primary-dark`  | `#134e4a` | teal-900 | 19, 78, 74    | Deep backgrounds, strong emphasis (dark) |
+
+### Color Usage Examples
+
+```jsx
+// Primary color for icons and emphasis
+<TagIcon className="text-brand-primary" />
+
+// Secondary color for primary action buttons
+<button className="bg-brand-secondary hover:bg-brand-dark">
+  Add to List
+</button>
+
+// Light backgrounds for selected/highlighted items
+<div className="bg-brand-light dark:bg-brand-dark/30">
+  Selected Flyer
+</div>
+
+// Focus rings on form inputs
+<input className="focus:ring-brand-primary focus:border-brand-primary" />
+```
+
+## Semantic Color Mappings
+
+### Primary (`brand-primary`)
+
+**Purpose**: Main brand color for visual identity and key interactive elements
+
+**Use Cases**:
+
+- Icons representing key features (shopping cart, tags, deals)
+- Hover states on links and interactive text
+- Focus indicators on form elements
+- Progress bars and loading indicators
+- Selected state indicators
+
+**Example Usage**:
+
+```jsx
+className = 'text-brand-primary hover:text-brand-dark';
+```
+
+### Secondary (`brand-secondary`)
+
+**Purpose**: Supporting actions and primary buttons that drive user engagement
+
+**Use Cases**:
+
+- Primary action buttons (Add, Submit, Save)
+- Call-to-action elements that require user attention
+- Active state for toggles and switches
+
+**Example Usage**:
+
+```jsx
+className = 'bg-brand-secondary hover:bg-brand-dark';
+```
+
+### Light (`brand-light`)
+
+**Purpose**: Subtle backgrounds and highlights in light mode
+
+**Use Cases**:
+
+- Selected item backgrounds
+- Highlighted sections
+- Drag-and-drop target areas
+- Subtle emphasis backgrounds
+
+**Example Usage**:
+
+```jsx
+className = 'bg-brand-light dark:bg-brand-dark/20';
+```
+
+### Dark (`brand-dark`)
+
+**Purpose**: Hover states and backgrounds in dark mode
+
+**Use Cases**:
+
+- Button hover states
+- Dark mode backgrounds for highlighted sections
+- Strong emphasis in dark theme
+
+**Example Usage**:
+
+```jsx
+className = 'hover:bg-brand-dark dark:bg-brand-dark/30';
+```
+
+## Dark Mode Variants
+
+All brand colors have dark mode variants defined using Tailwind's `dark:` prefix.
+
+### Dark Mode Mapping Table
+
+| Light Mode Class        | Dark Mode Class               | Purpose                              |
+| ----------------------- | ----------------------------- | ------------------------------------ |
+| `text-brand-primary`    | `dark:text-brand-light`       | Text readability on dark backgrounds |
+| `bg-brand-light`        | `dark:bg-brand-dark/20`       | Subtle backgrounds                   |
+| `bg-brand-primary`      | `dark:bg-brand-primary`       | Brand color maintained in both modes |
+| `hover:text-brand-dark` | `dark:hover:text-brand-light` | Interactive text hover               |
+| `border-brand-primary`  | `dark:border-brand-primary`   | Borders maintained in both modes     |
+
+### Dark Mode Best Practices
+
+1. **Contrast**: Ensure sufficient contrast (WCAG AA: 4.5:1 for text, 3:1 for UI)
+2. **Consistency**: Use `brand-primary` for icons in both modes (it works well on both backgrounds)
+3. **Backgrounds**: Use lighter opacity variants for dark mode backgrounds (e.g., `/20`, `/30`)
+4. **Text**: Swap `brand-dark` ↔ `brand-light` for text elements between modes
+
+## Accessibility
+
+### Color Contrast Ratios
+
+All color combinations meet WCAG 2.1 Level AA standards:
+
+| Foreground      | Background        | Contrast Ratio | Pass Level |
+| --------------- | ----------------- | -------------- | ---------- |
+| `brand-primary` | white             | 4.51:1         | AA         |
+| `brand-dark`    | white             | 7.82:1         | AAA        |
+| white           | `brand-primary`   | 4.51:1         | AA         |
+| white           | `brand-secondary` | 3.98:1         | AA Large   |
+| white           | `brand-dark`      | 7.82:1         | AAA        |
+| `brand-light`   | `brand-dark`      | 13.4:1         | AAA        |
+
+### Focus Indicators
+
+All interactive elements MUST have visible focus indicators using `focus:ring-2`:
+
+```jsx
+className = 'focus:ring-2 focus:ring-brand-primary focus:ring-offset-2';
+```
+
+### Color Blindness Considerations
+
+The teal color palette is accessible for most forms of color blindness:
+
+- **Deuteranopia** (green-weak): Teal appears as blue/cyan
+- **Protanopia** (red-weak): Teal appears as blue
+- **Tritanopia** (blue-weak): Teal appears as green
+
+The brand colors are always used alongside text labels and icons, never relying solely on color to convey information.
+
+## Implementation Notes
+
+### Tailwind Config
+
+Brand colors are defined in `tailwind.config.js`:
+
+```javascript
+theme: {
+  extend: {
+    colors: {
+      brand: {
+        primary: '#0d9488',
+        secondary: '#14b8a6',
+        light: '#ccfbf1',
+        dark: '#115e59',
+        'primary-light': '#99f6e4',
+        'primary-dark': '#134e4a',
+      },
+    },
+  },
+}
+```
+
+### Usage in Components
+
+Import and use brand colors with Tailwind utility classes:
+
+```jsx
+// Text colors
+<span className="text-brand-primary dark:text-brand-light">Price</span>
+
+// Background colors
+<div className="bg-brand-secondary hover:bg-brand-dark">Button</div>
+
+// Border colors
+<div className="border-2 border-brand-primary">Card</div>
+
+// Opacity variants
+<div className="bg-brand-light/50 dark:bg-brand-dark/20">Overlay</div>
+```
+
+## Future Considerations
+
+### Potential Extensions
+
+- **Success**: Consider adding semantic success color (green) for completed actions
+- **Warning**: Consider adding semantic warning color (amber) for alerts
+- **Error**: Consider adding semantic error color (red) for errors (already using red-\* palette)
+
+### Color Palette Expansion
+
+If the brand evolves, consider these complementary colors:
+
+- **Accent**: Warm coral/orange for limited-time deals
+- **Neutral**: Gray scale for backgrounds and borders (already using Tailwind's gray palette)

+
+---
+
+## Architecture
+
+### Production vs Development Parity
+
+The dev container was updated to match production architecture (ADR-014):
+
+| Component    | Production             | Dev Container (OLD)    | Dev Container (NEW)     |
+| ------------ | ---------------------- | ---------------------- | ----------------------- |
+| API Server   | PM2 cluster mode       | `npm run dev` (inline) | PM2 fork + tsx watch    |
+| Worker       | PM2 process            | Inline with API        | PM2 process + tsx watch |
+| Frontend     | Static files via NGINX | Vite standalone        | PM2 + Vite dev server   |
+| Logs         | PM2 logs -> Logstash   | Console only           | PM2 logs -> Logstash    |
+| Process Mgmt | PM2                    | None                   | PM2                     |
+
+### Container Startup Flow
+
+When the container starts (`scripts/dev-entrypoint.sh`):
+
+1. **NGINX** starts (HTTPS proxy for Vite and Bugsink)
+2. **Bugsink** starts (error tracking on port 8000)
+3. **Logstash** starts (log aggregation)
+4. **PM2** starts with `ecosystem.dev.config.cjs`:
+   - `flyer-crawler-api-dev` - API server
+   - `flyer-crawler-worker-dev` - Background worker
+   - `flyer-crawler-vite-dev` - Vite dev server
+5. Container tails PM2 logs to stay alive
+
+### Key Configuration Files
+
+| File                           | Purpose                            |
+| ------------------------------ | ---------------------------------- |
+| `ecosystem.dev.config.cjs`     | PM2 development configuration      |
+| `ecosystem.config.cjs`         | PM2 production configuration       |
+| `scripts/dev-entrypoint.sh`    | Container startup script           |

+
+## PM2 Process Management
+
+### Process Overview
+
+PM2 manages three processes in the dev container:
+
+```
++--------------------+     +------------------------+     +--------------------+
+|  flyer-crawler-    |     |  flyer-crawler-        |     |  flyer-crawler-    |
+|  api-dev           |     |  worker-dev            |     |  vite-dev          |
++--------------------+     +------------------------+     +--------------------+
+| tsx watch          |     | tsx watch              |     | vite --host        |
+| server.ts          |     | src/services/worker.ts |     |                    |
+| Port: 3001         |     | No port                |     | Port: 5173         |
++--------------------+     +------------------------+     +--------------------+
+         |                          |                              |
+         v                          v                              v
++------------------------------------------------------------------------+
+|                        /var/log/pm2/*.log                               |
+|                     (Logstash picks up for Bugsink)                     |
++------------------------------------------------------------------------+
+```
+
+### PM2 Commands
+
+All commands should be run inside the container:
+
+```bash
+# View process status
+podman exec -it flyer-crawler-dev pm2 status
+
+# View all logs (tail -f style)
+podman exec -it flyer-crawler-dev pm2 logs
+
+# View specific process logs
+podman exec -it flyer-crawler-dev pm2 logs flyer-crawler-api-dev
+
+# Restart all processes
+podman exec -it flyer-crawler-dev pm2 restart all
+
+# Restart specific process
+podman exec -it flyer-crawler-dev pm2 restart flyer-crawler-api-dev
+
+# Stop all processes
+podman exec -it flyer-crawler-dev pm2 delete all
+
+# Show detailed process info
+podman exec -it flyer-crawler-dev pm2 show flyer-crawler-api-dev
+
+# Monitor processes in real-time
+podman exec -it flyer-crawler-dev pm2 monit
+```
+
+### PM2 Log Locations
+
+| Process                    | stdout Log                    | stderr Log                      |

+| `flyer-crawler-vite-dev`   | `/var/log/pm2/vite-out.log`   | `/var/log/pm2/vite-error.log`   |
+
+### NPM Scripts for PM2
+
+The following npm scripts are available for PM2 management:
+
+```bash
+# Start PM2 with dev config (inside container)
+npm run dev:pm2
+
+# Restart all PM2 processes
+npm run dev:pm2:restart
+
+# Stop all PM2 processes
+npm run dev:pm2:stop
+
+# View PM2 status
+npm run dev:pm2:status
+
+# View PM2 logs
+npm run dev:pm2:logs
+```
+
+---
+
+## Log Aggregation
+
+### Log Flow Architecture (ADR-050)
+
+All application logs flow through Logstash to Bugsink:
+
+```
++------------------+     +------------------+     +------------------+
+|   PM2 Logs       |     |   PostgreSQL     |     |   Redis Logs     |

+## Troubleshooting
+
+### PM2 Process Not Starting
+
+**Symptom**: `pm2 status` shows process as "errored" or "stopped"
+
+**Debug**:
+
+```bash
+# Check process logs
+podman exec -it flyer-crawler-dev pm2 logs flyer-crawler-api-dev --lines 50
+
+# Check if port is in use
+podman exec -it flyer-crawler-dev netstat -tlnp | grep 3001
+
+# Try manual start to see errors
+podman exec -it flyer-crawler-dev tsx server.ts
+```
+
+**Common Causes**:
+
+- Port already in use
+- Missing environment variables
+- Syntax error in code
+
+### Logs Not Appearing in Bugsink
+
+**Symptom**: Errors in application but nothing in Bugsink UI
+
+**Debug**:
+
+```bash
+# Check Logstash is running
+podman exec flyer-crawler-dev curl -s localhost:9600/_node/stats/pipelines?pretty
+
+# Check Logstash logs for errors
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-dev cat /var/log/logstash/logstash.log
+
+# Verify PM2 logs exist
+podman exec flyer-crawler-dev ls -la /var/log/pm2/
+```
+
+**Common Causes**:
+
+- Logstash not started
+- Log file permissions
+- Bugsink not running
+
+### Redis Logs Not Captured
+
+**Symptom**: Redis warnings not appearing in Bugsink
+
+**Debug**:
+
+```bash
+# Verify Redis logs exist
+MSYS_NO_PATHCONV=1 podman exec flyer-crawler-redis cat /var/log/redis/redis-server.log
+
+# Verify shared volume is mounted
+podman exec flyer-crawler-dev ls -la /var/log/redis/
+```
+
+**Common Causes**:
+
+- `redis_logs` volume not mounted
+- Redis not configured to write to file
+
+### Hot Reload Not Working
+
+**Symptom**: Code changes not reflected in running application
+
+**Debug**:
+
+```bash
+# Check tsx watch is running
+podman exec -it flyer-crawler-dev pm2 logs flyer-crawler-api-dev
+
+# Manually restart process
+podman exec -it flyer-crawler-dev pm2 restart flyer-crawler-api-dev
+```
+
+**Common Causes**:
+
+- File watcher limit reached

+# Testing Guide
+
+## Overview
+
+This project has comprehensive test coverage including unit tests, integration tests, and E2E tests. All tests must be run in the **Linux dev container environment** for reliable results.
+
+## Test Execution Environment
+
+**CRITICAL**: All tests and type-checking MUST be executed inside the dev container (Linux environment).
+
+### Why Linux Only?
+
+- Path separators: Code uses POSIX-style paths (`/`) which may break on Windows
+- TypeScript compilation works differently on Windows vs Linux
+- Shell scripts and external dependencies assume Linux
+- Test results from Windows are **unreliable and should be ignored**
+
+### Running Tests Correctly
+
+#### Option 1: Inside Dev Container (Recommended)
+
+Open VS Code and use "Reopen in Container", then:
+
+```bash
+npm test                    # Run all tests
+npm run test:unit          # Run unit tests only
+npm run test:integration   # Run integration tests
+npm run type-check         # Run TypeScript type checking
+```
+
+#### Option 2: Via Podman from Windows Host
+
+From the Windows host, execute commands in the container:
+
+```bash
+# Run unit tests (2900+ tests - pipe to file for AI processing)
+podman exec -it flyer-crawler-dev npm run test:unit 2>&1 | tee test-results.txt
+
+# Run integration tests
+podman exec -it flyer-crawler-dev npm run test:integration
+
+# Run type checking
+podman exec -it flyer-crawler-dev npm run type-check
+
+# Run specific test file
+podman exec -it flyer-crawler-dev npm test -- --run src/hooks/useAuth.test.tsx
+```
+
+## Type Checking
+
+TypeScript type checking is performed using `tsc --noEmit`.
+
+### Type Check Command
+
+```bash
+npm run type-check
+```
+
+### Type Check Validation
+
+The type-check command will:
+
+- Exit with code 0 if no errors are found
+- Exit with non-zero code and print errors if type errors exist
+- Check all files in the `src/` directory as defined in `tsconfig.json`
+
+**IMPORTANT**: Type-check on Windows may not show errors reliably. Always verify type-check results by running in the dev container.
+
+### Verifying Type Check Works
+
+To verify type-check is working correctly:
+
+1. Run type-check in dev container: `podman exec -it flyer-crawler-dev npm run type-check`
+2. Check for output - errors will be displayed with file paths and line numbers
+3. No output + exit code 0 = no type errors
+
+Example error output:
+
+```
+src/pages/MyDealsPage.tsx:68:31 - error TS2339: Property 'store_name' does not exist on type 'WatchedItemDeal'.
+
+68                   <span>{deal.store_name}</span>
+                                  ~~~~~~~~~~
+```
+
+## Pre-Commit Hooks
+
+The project uses Husky and lint-staged for pre-commit validation:
+
+```bash
+# .husky/pre-commit
+npx lint-staged
+```
+
+Lint-staged configuration (`.lintstagedrc.json`):
+
+```json
+{
+  "*.{js,jsx,ts,tsx}": ["eslint --fix --no-color", "prettier --write"],
+  "*.{json,md,css,html,yml,yaml}": ["prettier --write"]
+}
+```
+
+**Note**: The `--no-color` flag prevents ANSI color codes from breaking file path links in git output.
+
+## Test Suite Structure
+
+### Unit Tests (~2900 tests)
+
+Located throughout `src/` directory alongside source files with `.test.ts` or `.test.tsx` extensions.
+
+```bash
+npm run test:unit
+```
+
+### Integration Tests (5 test files)
+
+Located in `src/tests/integration/`:
+
+- `admin.integration.test.ts`
+- `flyer.integration.test.ts`
+- `price.integration.test.ts`
+- `public.routes.integration.test.ts`
+- `receipt.integration.test.ts`
+
+Requires PostgreSQL and Redis services running.
+
+```bash
+npm run test:integration
+```
+
+### E2E Tests (3 test files)
+
+Located in `src/tests/e2e/`:
+
+- `deals-journey.e2e.test.ts`
+- `budget-journey.e2e.test.ts`
+- `receipt-journey.e2e.test.ts`
+
+Requires all services (PostgreSQL, Redis, BullMQ workers) running.
+
+```bash
+npm run test:e2e
+```
+
+## Test Result Interpretation
+
+- Tests that **pass on Windows but fail on Linux** = **BROKEN tests** (must be fixed)
+- Tests that **fail on Windows but pass on Linux** = **PASSING tests** (acceptable)
+- Always use **Linux (dev container) results** as the source of truth
+
+## Test Helpers
+
+### Store Test Helpers
+
+Located in `src/tests/utils/storeHelpers.ts`:
+
+```typescript
+// Create a store with a location in one call
+const store = await createStoreWithLocation({
+  storeName: 'Test Store',
+  address: {
+    address_line_1: '123 Main St',
+    city: 'Toronto',
+    province_state: 'ON',
+    postal_code: 'M1M 1M1',
+  },
+  pool,
+  log,
+});
+
+// Cleanup stores and their locations
+await cleanupStoreLocations([storeId1, storeId2], pool, log);
+```
+
+### Mock Factories
+
+Located in `src/tests/utils/mockFactories.ts`:
+
+```typescript
+// Create mock data for tests
+const mockStore = createMockStore({ name: 'Test Store' });
+const mockAddress = createMockAddress({ city: 'Toronto' });
+const mockStoreLocation = createMockStoreLocationWithAddress();
+const mockStoreWithLocations = createMockStoreWithLocations({
+  locations: [{ address: { city: 'Toronto' } }],
+});
+```
+
+### Test Assets
+
+Test images and other assets are located in `src/tests/assets/`:
+
+| File                   | Purpose                                        |
+| ---------------------- | ---------------------------------------------- |
+| `test-flyer-image.jpg` | Sample flyer image for upload/processing tests |
+| `test-flyer-icon.png`  | Sample flyer icon (64x64) for thumbnail tests  |
+
+These images are copied to `public/flyer-images/` by the seed script (`npm run seed`) and served via NGINX at `/flyer-images/`.
+
+## Known Integration Test Issues
+
+See `CLAUDE.md` for documentation of common integration test issues and their solutions, including:
+
+1. Vitest globalSetup context isolation
+2. BullMQ cleanup queue timing issues
+3. Cache invalidation after direct database inserts
+4. Unique filename requirements for file uploads
+5. Response format mismatches
+6. External service availability
+
+## Continuous Integration
+
+Tests run automatically on:
+
+- Pre-commit (via Husky hooks)
+- Pull request creation/update (via Gitea CI/CD)
+- Merge to main branch (via Gitea CI/CD)
+
+CI/CD configuration:
+
+- `.gitea/workflows/deploy-to-prod.yml`
+- `.gitea/workflows/deploy-to-test.yml`
+
+## Coverage Reports
+
+Test coverage is tracked using Vitest's built-in coverage tools.
+
+```bash
+npm run test:coverage
+```
+
+Coverage reports are generated in the `coverage/` directory.
+
+## Debugging Tests
+
+### Enable Verbose Logging
+
+```bash
+# Run tests with verbose output
+npm test -- --reporter=verbose
+
+# Run specific test with logging
+DEBUG=* npm test -- --run src/path/to/test.test.ts
+```
+
+### Using Vitest UI
+
+```bash
+npm run test:ui
+```
+
+Opens a browser-based test runner with filtering and debugging capabilities.
+
+## Best Practices
+
+1. **Always run tests in dev container** - never trust Windows test results
+2. **Run type-check before committing** - catches TypeScript errors early
+3. **Use test helpers** - `createStoreWithLocation()`, mock factories, etc.
+4. **Clean up test data** - use cleanup helpers in `afterEach`/`afterAll`
+5. **Verify cache invalidation** - tests that insert data directly must invalidate cache
+6. **Use unique filenames** - file upload tests need timestamp-based filenames
+7. **Check exit codes** - `npm run type-check` returns 0 on success, non-zero on error

+| `.env.test`                           | Test environment overrides (not in git)     |
+
+## Adding New Variables
+
+### 1. Update Zod Schema
+
+Edit `src/config/env.ts`:
+
+```typescript
+const envSchema = z.object({
+  // ... existing variables ...
+  NEW_VARIABLE: z.string().min(1),
+});
+```
+
+### 2. Add to Gitea Secrets
+
+For prod/test environments:
+
+1. Go to Gitea repository Settings > Secrets
+2. Add `NEW_VARIABLE` with value
+3. Add `NEW_VARIABLE_TEST` if test needs different value
+
+### 3. Update Deployment Workflows
+
+Edit `.gitea/workflows/deploy-to-prod.yml`:
+
+```yaml
+env:
+  NEW_VARIABLE: ${{ secrets.NEW_VARIABLE }}
+```
+
+Edit `.gitea/workflows/deploy-to-test.yml`:
+
+```yaml
+env:
+  NEW_VARIABLE: ${{ secrets.NEW_VARIABLE_TEST }}
+```
+
+### 4. Update PM2 Config
+
+Edit `ecosystem.config.cjs`:
+
+```javascript
+module.exports = {
+  apps: [
+    {
+      env: {
+        NEW_VARIABLE: process.env.NEW_VARIABLE,
+      },
+    },
+  ],
+};
+```
+
+### 5. Update Documentation
+
+- Add to `.env.example`
+- Update this document
+- Document in relevant feature docs
+
+## Security Best Practices
+
+### Secrets Management
+
+- **NEVER** commit secrets to git
+- Use Gitea Secrets for prod/test
+- Use `.env.local` for dev (gitignored)
+- Rotate secrets regularly
+
+### Secret Generation
+
+```bash
+# Generate secure random secrets
+node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
+```
+
+### Database Users
+
+Each environment has its own PostgreSQL user:
+
+| Environment | User                 | Database             |
+| ----------- | -------------------- | -------------------- |
+| Production  | `flyer_crawler_prod` | `flyer-crawler-prod` |
+| Test        | `flyer_crawler_test` | `flyer-crawler-test` |
+| Development | `postgres`           | `flyer_crawler_dev`  |
+
+**Setup Commands** (as postgres superuser):
+
+```sql
+-- Production
+CREATE DATABASE "flyer-crawler-prod";
+CREATE USER flyer_crawler_prod WITH PASSWORD 'secure-password';
+ALTER DATABASE "flyer-crawler-prod" OWNER TO flyer_crawler_prod;
+\c "flyer-crawler-prod"
+ALTER SCHEMA public OWNER TO flyer_crawler_prod;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_prod;
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+CREATE EXTENSION IF NOT EXISTS postgis;
+CREATE EXTENSION IF NOT EXISTS pg_trgm;
+
+-- Test (similar commands with _test suffix)
+```
+
+## Validation
+
+Environment variables are validated at startup via `src/config/env.ts`. If validation fails:
+
+1. Check the error message for missing/invalid variables
+2. Verify `.env.local` (dev) or Gitea Secrets (prod/test)
+3. Ensure values match schema requirements (min length, format, etc.)
+
+## Troubleshooting
+
+### Variable Not Found
+
+```
+Error: Missing required environment variable: JWT_SECRET
+```
+
+**Solution**: Add the variable to your environment configuration.
+
+### Invalid Value
+
+```
+Error: JWT_SECRET must be at least 32 characters
+```
+
+**Solution**: Generate a longer secret value.
+
+### Wrong Environment Selected
+
+Check `NODE_ENV` is set correctly:
+
+- `development` - Local dev container
+- `test` - CI/CD test server
+- `production` - Production server
+
+### Database Connection Issues
+
+Verify database credentials:
+
+```bash
+# Development
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "SELECT 1;"
+
+# Production (via SSH)
+ssh root@projectium.com "psql -U flyer_crawler_prod -d flyer-crawler-prod -c 'SELECT 1;'"
+```

+# Installation Guide
+
+This guide covers setting up a local development environment for Flyer Crawler.
+
+## Prerequisites
+
+- Node.js 20.x or later
+- Access to a PostgreSQL database (local or remote)
+- Redis instance (for session management)
+- Google Gemini API key
+- Google Maps API key (for geocoding)
+
+## Quick Start
+
+If you already have PostgreSQL and Redis configured:
+
+```bash
+# Install dependencies
+npm install
+
+# Run in development mode
+npm run dev
+```
+
+---
+
+## Development Environment with Podman (Recommended for Windows)
+
+This approach uses Podman with an Ubuntu container for a consistent development environment.
+
+### Step 1: Install Prerequisites on Windows
+
+1. **Install WSL 2**: Podman on Windows relies on the Windows Subsystem for Linux.
+
+   ```powershell
+   wsl --install
+   ```
+
+   Run this in an administrator PowerShell.
+
+2. **Install Podman Desktop**: Download and install [Podman Desktop for Windows](https://podman-desktop.io/).
+
+### Step 2: Set Up Podman
+
+1. **Initialize Podman**: Launch Podman Desktop. It will automatically set up its WSL 2 machine.
+2. **Start Podman**: Ensure the Podman machine is running from the Podman Desktop interface.
+
+### Step 3: Set Up the Ubuntu Container
+
+1. **Pull Ubuntu Image**:
+
+   ```bash
+   podman pull ubuntu:latest
+   ```
+
+2. **Create a Podman Volume** (persists node_modules between container restarts):
+
+   ```bash
+   podman volume create node_modules_cache
+   ```
+
+3. **Run the Ubuntu Container**:
+
+   Open a terminal in your project's root directory and run:
+
+   ```bash
+   podman run -it -p 3001:3001 -p 5173:5173 --name flyer-dev \
+     -v "$(pwd):/app" \
+     -v "node_modules_cache:/app/node_modules" \
+     ubuntu:latest
+   ```
+
+   | Flag                                        | Purpose                                          |
+   | ------------------------------------------- | ------------------------------------------------ |
+   | `-p 3001:3001`                              | Forwards the backend server port                 |
+   | `-p 5173:5173`                              | Forwards the Vite frontend server port           |
+   | `--name flyer-dev`                          | Names the container for easy reference           |
+   | `-v "...:/app"`                             | Mounts your project directory into the container |
+   | `-v "node_modules_cache:/app/node_modules"` | Mounts the named volume for node_modules         |
+
+### Step 4: Configure the Ubuntu Environment
+
+You are now inside the Ubuntu container's shell.
+
+1. **Update Package Lists**:
+
+   ```bash
+   apt-get update
+   ```
+
+2. **Install Dependencies**:
+
+   ```bash
+   apt-get install -y curl git
+   curl -sL https://deb.nodesource.com/setup_20.x | bash -
+   apt-get install -y nodejs
+   ```
+
+3. **Navigate to Project Directory**:
+
+   ```bash
+   cd /app
+   ```
+
+4. **Install Project Dependencies**:
+
+   ```bash
+   npm install
+   ```
+
+### Step 5: Run the Development Server
+
+```bash
+npm run dev
+```
+
+### Step 6: Access the Application
+
+- **Frontend**: http://localhost:5173
+- **Backend API**: http://localhost:3001
+
+### Dev Container with HTTPS (Full Stack)
+
+When using the full dev container stack with NGINX (via `compose.dev.yml`), access the application over HTTPS:
+
+- **Frontend**: https://localhost or https://127.0.0.1
+- **Backend API**: http://localhost:3001
+
+**SSL Certificate Notes:**
+
+- The dev container uses self-signed certificates generated by mkcert
+- Both `localhost` and `127.0.0.1` are valid hostnames (certificate includes both as SANs)
+- If images fail to load with SSL errors, see [FLYER-URL-CONFIGURATION.md](../FLYER-URL-CONFIGURATION.md#ssl-certificate-configuration-dev-container)
+
+**Eliminate SSL Warnings (Recommended):**
+
+To avoid browser security warnings for self-signed certificates, install the mkcert CA certificate on your system. The CA certificate is located at `certs/mkcert-ca.crt` in the project root.
+
+See [`certs/README.md`](../../certs/README.md) for platform-specific installation instructions (Windows, macOS, Linux, Firefox).
+
+After installation:
+
+- Your browser will trust all mkcert certificates without warnings
+- Both `https://localhost/` and `https://127.0.0.1/` will work without SSL errors
+- Flyer images will load without `ERR_CERT_AUTHORITY_INVALID` errors
+
+### Managing the Container
+
+| Action                | Command                          |
+| --------------------- | -------------------------------- |
+| Stop the container    | Press `Ctrl+C`, then type `exit` |
+| Restart the container | `podman start -a -i flyer-dev`   |
+| Remove the container  | `podman rm flyer-dev`            |
+
+---
+
+## Environment Variables
+
+This project is configured to run in a CI/CD environment and does not use `.env` files. All configuration must be provided as environment variables.
+
+For local development, you can export these in your shell or use your IDE's environment configuration:
+
+| Variable                    | Description                           |
+| --------------------------- | ------------------------------------- |
+| `DB_HOST`                   | PostgreSQL server hostname            |
+| `DB_USER`                   | PostgreSQL username                   |
+| `DB_PASSWORD`               | PostgreSQL password                   |
+| `DB_DATABASE_PROD`          | Production database name              |
+| `JWT_SECRET`                | Secret string for signing auth tokens |
+| `VITE_GOOGLE_GENAI_API_KEY` | Google Gemini API key                 |
+| `GOOGLE_MAPS_API_KEY`       | Google Maps Geocoding API key         |
+| `REDIS_PASSWORD_PROD`       | Production Redis password             |
+| `REDIS_PASSWORD_TEST`       | Test Redis password                   |
+
+---
+
+## Seeding Development Data
+
+To create initial test accounts (`admin@example.com` and `user@example.com`) and sample data:
+
+```bash
+npm run seed
+```
+
+The seed script performs the following actions:
+
+1. Rebuilds the database schema from `sql/master_schema_rollup.sql`
+2. Creates test user accounts (admin and regular user)
+3. Copies test flyer images from `src/tests/assets/` to `public/flyer-images/`
+4. Creates a sample flyer with items linked to the test images
+5. Seeds watched items and a shopping list for the test user
+
+**Test Images**: The seed script copies `test-flyer-image.jpg` and `test-flyer-icon.png` to the `public/flyer-images/` directory, which is served by NGINX at `/flyer-images/`.
+
+After running, you may need to restart your IDE's TypeScript server to pick up any generated types.

+# Quick Start Guide
+
+Get Flyer Crawler running in 5 minutes.
+
+## Prerequisites
+
+- **Windows 10/11** with WSL 2
+- **Podman Desktop** installed
+- **Node.js 20+** installed
+
+## 1. Start Containers (1 minute)
+
+```bash
+# Start PostgreSQL and Redis
+podman start flyer-crawler-postgres flyer-crawler-redis
+
+# If containers don't exist yet, create them:
+podman run -d --name flyer-crawler-postgres \
+  -e POSTGRES_USER=postgres \
+  -e POSTGRES_PASSWORD=postgres \
+  -e POSTGRES_DB=flyer_crawler_dev \
+  -p 5432:5432 \
+  docker.io/postgis/postgis:15-3.3
+
+podman run -d --name flyer-crawler-redis \
+  -p 6379:6379 \
+  docker.io/library/redis:alpine
+```
+
+## 2. Initialize Database (2 minutes)
+
+```bash
+# Wait for PostgreSQL to be ready
+podman exec flyer-crawler-postgres pg_isready -U postgres
+
+# Install extensions
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev \
+  -c "CREATE EXTENSION IF NOT EXISTS postgis; CREATE EXTENSION IF NOT EXISTS pg_trgm; CREATE EXTENSION IF NOT EXISTS \"uuid-ossp\";"
+
+# Apply schema
+podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/master_schema_rollup.sql
+```
+
+## 3. Configure Environment (1 minute)
+
+Create `.env.local` in the project root:
+
+```bash
+# Database
+DB_HOST=localhost
+DB_USER=postgres
+DB_PASSWORD=postgres
+DB_NAME=flyer_crawler_dev
+DB_PORT=5432
+
+# Redis
+REDIS_URL=redis://localhost:6379
+
+# Application
+NODE_ENV=development
+PORT=3001
+FRONTEND_URL=http://localhost:5173
+
+# Secrets (generate your own)
+JWT_SECRET=your-dev-jwt-secret-at-least-32-chars-long
+SESSION_SECRET=your-dev-session-secret-at-least-32-chars-long
+
+# AI Services (get your own keys)
+VITE_GOOGLE_GENAI_API_KEY=your-google-genai-api-key
+GOOGLE_MAPS_API_KEY=your-google-maps-api-key
+```
+
+## 4. Install & Run (1 minute)
+
+```bash
+# Install dependencies (first time only)
+npm install
+
+# Start development server
+npm run dev
+```
+
+## 5. Access Application
+
+- **Frontend**: http://localhost:5173
+- **Backend API**: http://localhost:3001
+- **Health Check**: http://localhost:3001/health
+
+### Dev Container (HTTPS)
+
+When using the full dev container with NGINX, access via HTTPS:
+
+- **Frontend**: https://localhost or https://127.0.0.1
+- **Backend API**: http://localhost:3001
+- **Bugsink**: `https://localhost:8443` (error tracking)
+
+**Note:** The dev container accepts both `localhost` and `127.0.0.1` for HTTPS connections. The self-signed certificate is valid for both hostnames.
+
+**SSL Certificate Warnings:** To eliminate browser security warnings for self-signed certificates, install the mkcert CA certificate. See [`certs/README.md`](../../certs/README.md) for platform-specific installation instructions. This is optional but recommended for a better development experience.
+
+### Dev Container Architecture
+
+The dev container uses PM2 for process management, matching production (ADR-014):
+
+| Process                    | Description              | Port |
+| -------------------------- | ------------------------ | ---- |
+| `flyer-crawler-api-dev`    | API server (tsx watch)   | 3001 |
+| `flyer-crawler-worker-dev` | Background job worker    | -    |
+| `flyer-crawler-vite-dev`   | Vite frontend dev server | 5173 |
+
+**PM2 Commands** (run inside container):
+
+```bash
+# View process status
+podman exec -it flyer-crawler-dev pm2 status
+
+# View logs (all processes)
+podman exec -it flyer-crawler-dev pm2 logs
+
+# Restart all processes
+podman exec -it flyer-crawler-dev pm2 restart all
+
+# Restart specific process
+podman exec -it flyer-crawler-dev pm2 restart flyer-crawler-api-dev
+```
+
+## Verify Installation
+
+```bash
+# Check containers are running
+podman ps
+
+# Test database connection
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "SELECT version();"
+
+# Run tests (in dev container)
+podman exec -it flyer-crawler-dev npm run test:unit
+```
+
+## Common Issues
+
+### "Unable to connect to Podman socket"
+
+```bash
+podman machine start
+```
+
+### "Connection refused" to PostgreSQL
+
+Wait a few seconds for PostgreSQL to initialize:
+
+```bash
+podman exec flyer-crawler-postgres pg_isready -U postgres
+```
+
+### Port 5432 or 6379 already in use
+
+Stop conflicting services or change port mappings:
+
+```bash
+# Use different host port
+podman run -d --name flyer-crawler-postgres -p 5433:5432 ...
+```
+
+Then update `DB_PORT=5433` in `.env.local`.
+

+# Deployment Guide
+
+This guide covers deploying Flyer Crawler to a production server.
+
+## Prerequisites
+
+- Ubuntu server (22.04 LTS recommended)
+- PostgreSQL 14+ with PostGIS extension
+- Redis
+- Node.js 20.x
+- NGINX (reverse proxy)
+- PM2 (process manager)
+
+## Dev Container Parity (ADR-014)
+
+The development container now matches production architecture:
+
+| Component    | Production       | Dev Container              |
+| ------------ | ---------------- | -------------------------- |
+| Process Mgmt | PM2              | PM2                        |
+| API Server   | PM2 cluster mode | PM2 fork + tsx watch       |
+| Worker       | PM2 process      | PM2 process + tsx watch    |
+| Logs         | PM2 -> Logstash  | PM2 -> Logstash -> Bugsink |
+| HTTPS        | Let's Encrypt    | Self-signed (mkcert)       |
+
+This ensures issues caught in dev will behave the same in production.
+
+**Dev Container Guide**: See [docs/development/DEV-CONTAINER.md](../development/DEV-CONTAINER.md)
+

+| `etc-nginx-sites-available-flyer-crawler.projectium.com`          | Production NGINX config   |
+| `etc-nginx-sites-available-flyer-crawler-test-projectium-com.txt` | Test/staging NGINX config |
+
+**Important Notes:**
+
+- These are **reference copies only** - they are not used directly by NGINX
+- The actual live configurations reside on the server at `/etc/nginx/sites-available/`
+- When modifying server NGINX configs, update these reference files to keep them in sync
+- Use the dev container config at `docker/nginx/dev.conf` for local development
+
+### Reverse Proxy Setup
+
+Create a site configuration at `/etc/nginx/sites-available/flyer-crawler.projectium.com`:
+
+```nginx
+server {
+    listen 80;
+    server_name flyer-crawler.projectium.com;
+
+    location / {
+        proxy_pass http://localhost:5173;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+
+    location /api {
+        proxy_pass http://localhost:3001;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+
+    # Serve flyer images from static storage (7-day cache)
+    location /flyer-images/ {
+        alias /var/www/flyer-crawler.projectium.com/flyer-images/;
+        expires 7d;
+        add_header Cache-Control "public, immutable";
+    }
+}
+```
+
+### Static Flyer Images
+
+Flyer images are served as static files from the `/flyer-images/` path with browser caching enabled:
+
+| Environment   | Directory                                                  | URL Pattern                                               |
+| ------------- | ---------------------------------------------------------- | --------------------------------------------------------- |
+| Production    | `/var/www/flyer-crawler.projectium.com/flyer-images/`      | `https://flyer-crawler.projectium.com/flyer-images/`      |
+| Test          | `/var/www/flyer-crawler-test.projectium.com/flyer-images/` | `https://flyer-crawler-test.projectium.com/flyer-images/` |
+| Dev Container | `/app/public/flyer-images/`                                | `https://localhost/flyer-images/`                         |
+
+**Cache Settings**: Files are served with `expires 7d` and `Cache-Control: public, immutable` headers for optimal browser caching.
+
+Create the flyer images directory if it does not exist:
+
+```bash
+sudo mkdir -p /var/www/flyer-crawler.projectium.com/flyer-images
+sudo chown www-data:www-data /var/www/flyer-crawler.projectium.com/flyer-images
+```
+
+Enable the site:
+
+```bash
+sudo ln -s /etc/nginx/sites-available/flyer-crawler.projectium.com /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+### MIME Types Fix for .mjs Files
+
+If JavaScript modules (`.mjs` files) aren't loading correctly, add the proper MIME type.
+
+**Option 1**: Edit the site configuration file directly:
+
+```nginx
+# Add inside the server block
+types {
+    application/javascript js mjs;
+}
+```
+
+**Option 2**: Edit `/etc/nginx/mime.types` globally:
+
+```
+# Change this line:
+application/javascript js;
+
+# To:
+application/javascript js mjs;
+```
+
+After changes:
+
+```bash
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+---
+
+## PM2 Log Management
+
+Install and configure pm2-logrotate to manage log files:
+
+```bash
+pm2 install pm2-logrotate
+pm2 set pm2-logrotate:max_size 10M
+pm2 set pm2-logrotate:retain 14
+pm2 set pm2-logrotate:compress false
+pm2 set pm2-logrotate:dateFormat YYYY-MM-DD_HH-mm-ss
+```
+
+---
+
+## Rate Limiting
+
+The application respects the Gemini AI service's rate limits. You can adjust the `GEMINI_RPM` (requests per minute) environment variable in production as needed without changing the code.
+
+---
+
+## CI/CD Pipeline
+
+The project includes Gitea workflows at `.gitea/workflows/deploy.yml` that:
+
+1. Run tests against a test database
+2. Build the application
+3. Deploy to production on successful builds
+
+The workflow automatically:
+
+- Sets up the test database schema before tests
+- Tears down test data after tests complete
+- Deploys to the production server
+
+---
+
+## Monitoring
+
+### Check PM2 Status
+
+```bash
+pm2 status
+pm2 logs
+pm2 logs flyer-crawler-api --lines 100
+```
+
+### Restart Services
+
+```bash
+pm2 restart all
+pm2 restart flyer-crawler-api
+```
+
+---
+
+## Error Tracking with Bugsink (ADR-015)
+
+Bugsink is a self-hosted Sentry-compatible error tracking system. See [docs/adr/0015-application-performance-monitoring-and-error-tracking.md](docs/adr/0015-application-performance-monitoring-and-error-tracking.md) for the full architecture decision.
+
+### Creating Bugsink Projects and DSNs
+
+After Bugsink is installed and running, you need to create projects and obtain DSNs:
+
+1. **Access Bugsink UI**: Navigate to `http://localhost:8000`
+
+2. **Log in** with your admin credentials
+
+3. **Create Backend Project**:
+   - Click "Create Project"
+   - Name: `flyer-crawler-backend`
+   - Platform: Node.js
+   - Copy the generated DSN (format: `http://<key>@localhost:8000/<project_id>`)
+
+4. **Create Frontend Project**:
+   - Click "Create Project"
+   - Name: `flyer-crawler-frontend`
+   - Platform: React
+   - Copy the generated DSN
+
+5. **Configure Environment Variables**:
+
+   ```bash
+   # Backend (server-side)
+   export SENTRY_DSN=http://<backend-key>@localhost:8000/<backend-project-id>
+
+   # Frontend (client-side, exposed to browser)
+   export VITE_SENTRY_DSN=http://<frontend-key>@localhost:8000/<frontend-project-id>
+
+   # Shared settings
+   export SENTRY_ENVIRONMENT=production
+   export VITE_SENTRY_ENVIRONMENT=production
+   export SENTRY_ENABLED=true
+   export VITE_SENTRY_ENABLED=true
+   ```
+
+### Testing Error Tracking
+
+Verify Bugsink is receiving events:
+
+```bash
+npx tsx scripts/test-bugsink.ts
+```
+
+This sends test error and info events. Check the Bugsink UI for:
+
+- `BugsinkTestError` in the backend project
+- Info message "Test info message from test-bugsink.ts"
+
+### Sentry SDK v10+ HTTP DSN Limitation
+
+The Sentry SDK v10+ enforces HTTPS-only DSNs by default. Since Bugsink runs locally over HTTP, our implementation uses the Sentry Store API directly instead of the SDK's built-in transport. This is handled transparently by the `sentry.server.ts` and `sentry.client.ts` modules.

+# Logstash Quick Reference (ADR-050)
+
+Aggregates logs from PostgreSQL, PM2, Redis, NGINX; forwards errors to Bugsink.
+
+## Configuration
+
+**Primary config**: `/etc/logstash/conf.d/bugsink.conf`

+
+| Path                                                | Purpose                   |
+| --------------------------------------------------- | ------------------------- |
+| `/etc/postgresql/14/main/conf.d/observability.conf` | PostgreSQL logging config |
+| `/var/log/postgresql/*.log`                         | PostgreSQL logs           |
+| `/home/gitea-runner/.pm2/logs/*.log`                | PM2 worker logs           |
+| `/var/log/redis/redis-server.log`                   | Redis logs                |

+| `/var/lib/logstash/sincedb_*`                       | Position tracking files   |
+
+## Features
+
+- **Multi-source aggregation**: PostgreSQL, PM2 workers, Redis, NGINX
+- **Environment routing**: Auto-detects prod/test, routes to correct Bugsink project
+- **JSON parsing**: Extracts `fn_log()` from PostgreSQL, Pino JSON from PM2
+- **Sentry format**: Transforms to `event_id`, `timestamp`, `level`, `message`, `extra`
+- **Error filtering**: Only forwards WARNING/ERROR to Bugsink
+- **Operational storage**: Non-error logs saved to `/var/log/logstash/`
+- **Request monitoring**: NGINX requests categorized by status, slow request detection

+# Logstash Troubleshooting Runbook
+
+This runbook provides step-by-step diagnostics and solutions for common Logstash issues in the PostgreSQL observability pipeline (ADR-050).
+
+## Quick Reference
+
+| Symptom                  | Most Likely Cause            | Quick Check                           |
+| ------------------------ | ---------------------------- | ------------------------------------- |
+| No errors in Bugsink     | Logstash not running         | `systemctl status logstash`           |
+| Events not processed     | Grok pattern mismatch        | Check filter failures in stats        |
+| Wrong Bugsink project    | Environment detection failed | Verify `pg_database` field extraction |
+| 403 authentication error | Missing/wrong DSN key        | Check `X-Sentry-Auth` header          |
+| 500 error from Bugsink   | Invalid event format         | Verify `event_id` and required fields |
+
+---
+
+## Diagnostic Steps
+
+### 1. Verify Logstash is Running
+
+```bash
+# Check service status
+systemctl status logstash
+
+# If stopped, start it
+systemctl start logstash
+
+# View recent logs
+journalctl -u logstash -n 50 --no-pager
+```
+
+**Expected output:**
+
+- Status: `active (running)`
+- No error messages in recent logs
+
+---
+
+### 2. Check Configuration Syntax
+
+```bash
+# Test configuration file
+/usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/bugsink.conf
+```
+
+**Expected output:**
+
+```
+Configuration OK
+```
+
+**If syntax errors:**
+
+1. Review error message for line number
+2. Check for missing braces, quotes, or commas
+3. Verify plugin names are correct (e.g., `json`, `grok`, `uuid`, `http`)
+
+---
+
+### 3. Verify PostgreSQL Logs Are Being Read
+
+```bash
+# Check if log file exists and has content
+ls -lh /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log
+
+# Check Logstash can read the file
+sudo -u logstash cat /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log | head -10
+```
+
+**Expected output:**
+
+- Log file exists and is not empty
+- Logstash user can read the file without permission errors
+
+**If permission denied:**
+
+```bash
+# Check Logstash is in postgres group
+groups logstash
+
+# Should show: logstash : logstash adm postgres
+
+# If not, add to group
+usermod -a -G postgres logstash
+systemctl restart logstash
+```
+
+---
+
+### 4. Check Logstash Pipeline Stats
+
+```bash
+# Get pipeline statistics
+curl -XGET 'localhost:9600/_node/stats/pipelines?pretty' | jq '.pipelines.main.plugins.filters'
+```
+
+**Key metrics to check:**
+
+1. **Grok filter events:**
+   - `"events.in"` - Total events received
+   - `"events.out"` - Events successfully parsed
+   - `"failures"` - Events that failed to parse
+
+   **If failures > 0:** Grok pattern doesn't match log format. Check PostgreSQL log format.
+
+2. **JSON filter events:**
+   - `"events.in"` - Events received by JSON parser
+   - `"events.out"` - Successfully parsed JSON
+
+   **If events.in = 0:** Regex check `pg_message =~ /^\{/` is not matching. Verify fn_log() output format.
+
+3. **UUID filter events:**
+   - Should match number of errors being forwarded
+
+---
+
+### 5. Test Grok Pattern Manually
+
+```bash
+# Get a sample log line
+tail -1 /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log
+
+# Example expected format:
+# 2026-01-20 10:30:00 +05 [12345] flyer_crawler_prod@flyer-crawler-prod WARNING:  {"level":"WARNING","source":"postgresql",...}
+```
+
+**Pattern breakdown:**
+
+```
+%{TIMESTAMP_ISO8601:pg_timestamp}   # 2026-01-20 10:30:00
+[+-]%{INT:pg_timezone}               # +05
+\[%{POSINT:pg_pid}\]                 # [12345]
+%{DATA:pg_user}@%{DATA:pg_database}  # flyer_crawler_prod@flyer-crawler-prod
+%{WORD:pg_level}:                    # WARNING:
+%{GREEDYDATA:pg_message}             # (rest of line)
+```
+
+**If pattern doesn't match:**
+
+1. Check PostgreSQL `log_line_prefix` setting in `/etc/postgresql/14/main/conf.d/observability.conf`
+2. Should be: `log_line_prefix = '%t [%p] %u@%d '`
+3. Restart PostgreSQL if changed: `systemctl restart postgresql`
+
+---
+
+### 6. Verify Environment Detection
+
+```bash
+# Check recent PostgreSQL logs for database field
+tail -20 /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log | grep -E "flyer-crawler-(prod|test)"
+```
+
+**Expected:**
+
+- Production database: `flyer_crawler_prod@flyer-crawler-prod`
+- Test database: `flyer_crawler_test@flyer-crawler-test`
+
+**If database name doesn't match:**
+
+- Check database connection string in application
+- Verify `DB_DATABASE_PROD` and `DB_DATABASE_TEST` Gitea secrets
+
+---
+
+### 7. Test Bugsink API Connection
+
+```bash
+# Test production endpoint
+curl -X POST https://bugsink.projectium.com/api/1/store/ \
+  -H "X-Sentry-Auth: Sentry sentry_version=7, sentry_client=test/1.0, sentry_key=911aef02b9a548fa8fabb8a3c81abfe5" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "event_id": "12345678901234567890123456789012",
+    "timestamp": "2026-01-20T10:30:00Z",
+    "platform": "other",
+    "level": "error",
+    "logger": "test",
+    "message": "Test error from troubleshooting"
+  }'
+```
+
+**Expected response:**
+
+- HTTP 200 OK
+- Response body: `{"id": "..."}`
+
+**If 403 Forbidden:**
+
+- DSN key is wrong in `/etc/logstash/conf.d/bugsink.conf`
+- Get correct key from Bugsink UI: Settings → Projects → DSN
+
+**If 500 Internal Server Error:**
+
+- Missing required fields (event_id, timestamp, level)
+- Check `mapping` section in Logstash config
+
+---
+
+### 8. Monitor Logstash Output in Real-Time
+
+```bash
+# Watch Logstash processing logs
+journalctl -u logstash -f
+```
+
+**What to look for:**
+
+- `"response code => 200"` - Successful forwarding to Bugsink
+- `"response code => 403"` - Authentication failure
+- `"response code => 500"` - Invalid event format
+- Grok parse failures
+
+---
+
+## Common Issues and Solutions
+
+### Issue 1: Grok Pattern Parse Failures
+
+**Symptoms:**
+
+- Logstash stats show increasing `"failures"` count
+- No events reaching Bugsink
+
+**Diagnosis:**
+
+```bash
+curl -XGET 'localhost:9600/_node/stats/pipelines?pretty' | jq '.pipelines.main.plugins.filters[] | select(.name == "grok") | .failures'
+```
+
+**Solution:**
+
+1. Check PostgreSQL log format matches expected pattern
+2. Verify `log_line_prefix` in PostgreSQL config
+3. Test with sample log line using Grok Debugger (Kibana Dev Tools)
+
+---
+
+### Issue 2: JSON Filter Not Parsing fn_log() Output
+
+**Symptoms:**
+
+- Grok parses successfully but JSON filter shows 0 events
+- `[fn_log]` fields missing in Logstash output
+
+**Diagnosis:**
+
+```bash
+# Check if pg_message field contains JSON
+tail -20 /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log | grep "WARNING:" | grep "{"
+```
+
+**Solution:**
+
+1. Verify `fn_log()` function exists in database:
+   ```sql
+   \df fn_log
+   ```
+2. Test `fn_log()` output format:
+   ```sql
+   SELECT fn_log('WARNING', 'test', 'Test message', '{"key":"value"}'::jsonb);
+   ```
+3. Check logs show JSON output starting with `{`
+
+---
+
+### Issue 3: Events Going to Wrong Bugsink Project
+
+**Symptoms:**
+
+- Production errors appear in test project (or vice versa)
+
+**Diagnosis:**
+
+```bash
+# Check database name detection in recent logs
+tail -50 /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log | grep -E "(flyer-crawler-prod|flyer-crawler-test)"
+```
+
+**Solution:**
+
+1. Verify database names in filter section match actual database names
+2. Check `pg_database` field is correctly extracted by grok pattern:
+   ```bash
+   # Enable debug output in Logstash config temporarily
+   stdout { codec => rubydebug { metadata => true } }
+   ```
+3. Verify environment tagging in filter:
+   - `pg_database == "flyer-crawler-prod"` → adds "production" tag → routes to project 1
+   - `pg_database == "flyer-crawler-test"` → adds "test" tag → routes to project 3

+
+### Issue 4: 403 Authentication Errors from Bugsink
+
+**Symptoms:**
+
+- Logstash logs show `response code => 403`
+- Events not appearing in Bugsink
+
+**Diagnosis:**
+
+```bash
+# Check Logstash output logs for authentication errors
+journalctl -u logstash -n 100 | grep "403"
+```
+
+**Solution:**
+
+1. Verify DSN key in `/etc/logstash/conf.d/bugsink.conf` matches Bugsink project
+2. Get correct DSN from Bugsink UI:
+   - Navigate to Settings → Projects → Click project
+   - Copy "DSN" value
+   - Extract key: `http://KEY@host/PROJECT_ID` → use KEY
+3. Update `X-Sentry-Auth` header in Logstash config:
+   ```conf
+   "X-Sentry-Auth" => "Sentry sentry_version=7, sentry_client=logstash/1.0, sentry_key=YOUR_KEY_HERE"
+   ```
+4. Restart Logstash: `systemctl restart logstash`
+
+---
+
+### Issue 5: 500 Errors from Bugsink
+
+**Symptoms:**
+
+- Logstash logs show `response code => 500`
+- Bugsink logs show validation errors
+
+**Diagnosis:**
+
+```bash
+# Check Bugsink logs for details
+docker logs bugsink-web 2>&1 | tail -50
+```
+
+**Common causes:**
+
+1. Missing `event_id` field
+2. Invalid timestamp format
+3. Missing required Sentry fields
+
+**Solution:**
+
+1. Verify `uuid` filter is generating `event_id`:
+   ```conf
+   uuid {
+     target => "[@metadata][event_id]"
+     overwrite => true
+   }
+   ```
+2. Check `mapping` section includes all required fields:
+   - `event_id` (UUID)
+   - `timestamp` (ISO 8601)
+   - `platform` (string)
+   - `level` (error/warning/info)
+   - `logger` (string)
+   - `message` (string)
+
+---
+
+### Issue 6: High Memory Usage by Logstash
+
+**Symptoms:**
+
+- Server running out of memory
+- Logstash OOM killed
+
+**Diagnosis:**
+
+```bash
+# Check Logstash memory usage
+ps aux | grep logstash
+systemctl status logstash
+```
+
+**Solution:**
+
+1. Limit Logstash heap size in `/etc/logstash/jvm.options`:
+   ```
+   -Xms1g
+   -Xmx1g
+   ```
+2. Restart Logstash: `systemctl restart logstash`
+3. Monitor with: `top -p $(pgrep -f logstash)`
+
+---
+
+### Issue 7: Log File Rotation Issues
+
+**Symptoms:**
+
+- Logstash stops processing after log file rotates
+- Sincedb file pointing to old inode
+
+**Diagnosis:**
+
+```bash
+# Check sincedb file
+cat /var/lib/logstash/sincedb_postgres
+
+# Check current log file inode
+ls -li /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log
+```
+
+**Solution:**
+
+1. Logstash should automatically detect rotation
+2. If stuck, delete sincedb file (will reprocess recent logs):
+   ```bash
+   systemctl stop logstash
+   rm /var/lib/logstash/sincedb_postgres
+   systemctl start logstash
+   ```
+
+---
+
+## Verification Checklist
+
+After making any changes, verify the pipeline is working:
+
+- [ ] Logstash is running: `systemctl status logstash`
+- [ ] Configuration is valid: `/usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/bugsink.conf`
+- [ ] No grok failures: `curl localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.plugins.filters[] | select(.name == "grok") | .failures'`
+- [ ] Events being processed: `curl localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.events'`
+- [ ] Test error appears in Bugsink: Trigger a database function error and check Bugsink UI
+
+---
+
+## Test Database Function Error
+
+To generate a test error for verification:
+
+```bash
+# Connect to production database
+sudo -u postgres psql -d flyer-crawler-prod
+
+# Trigger an error (achievement not found)
+SELECT award_achievement('00000000-0000-0000-0000-000000000001'::uuid, 'Nonexistent Badge');
+\q
+```
+
+**Expected flow:**
+
+1. PostgreSQL logs the error to `/var/log/postgresql/postgresql-YYYY-MM-DD.log`
+2. Logstash reads and parses the log (within ~30 seconds)
+3. Error appears in Bugsink project 1 (production)
+
+**If error doesn't appear:**
+
+- Check each diagnostic step above
+- Review Logstash logs: `journalctl -u logstash -f`
+
+---

+
+### Endpoint Reference
+
+| Endpoint                | Purpose                | Use Case                                |
+| ----------------------- | ---------------------- | --------------------------------------- |
+| `/api/health/ping`      | Simple connectivity    | Quick "is it running?" check            |
+| `/api/health/live`      | Liveness probe         | Container orchestration restart trigger |
+| `/api/health/ready`     | Readiness probe        | Load balancer traffic routing           |
+| `/api/health/startup`   | Startup probe          | Initial container readiness             |
+| `/api/health/db-schema` | Schema verification    | Deployment validation                   |
+| `/api/health/db-pool`   | Connection pool status | Performance diagnostics                 |

+| `/api/health/time`      | Server time sync       | Time-sensitive operations               |
+
+### Liveness Probe (`/api/health/live`)
+
+Returns 200 OK if the Node.js process is running. No external dependencies.
+
+```bash
+# Check liveness
+curl -s https://flyer-crawler.projectium.com/api/health/live | jq .
+
+# Expected response
+{
+  "success": true,
+  "data": {
+    "status": "ok",
+    "timestamp": "2026-01-22T10:00:00.000Z"
+  }
+}
+```
+
+**Usage**: If this endpoint fails, restart the application immediately.
+
+### Readiness Probe (`/api/health/ready`)
+
+Comprehensive check of all critical dependencies: database, Redis, and storage.
+
+```bash
+# Check readiness
+curl -s https://flyer-crawler.projectium.com/api/health/ready | jq .
+
+# Expected healthy response (200)
+{
+  "success": true,
+  "data": {
+    "status": "healthy",
+    "timestamp": "2026-01-22T10:00:00.000Z",

+        }
+      }
+    }
+  }
+}
+```
+
+**Status Values**:
+
+| Status      | Meaning                                          | Action                    |
+| ----------- | ------------------------------------------------ | ------------------------- |
+| `healthy`   | All critical services operational                | None required             |
+| `degraded`  | Non-critical issues (e.g., high connection wait) | Monitor closely           |
+| `unhealthy` | Critical service unavailable (returns 503)       | Remove from load balancer |
+

+- Release/version information
+
+### Accessing Errors via MCP
+
+Claude Code and other AI tools can access Bugsink via MCP servers.
+
+**Available MCP Tools**:
+
+```bash
+# List all projects
+mcp__bugsink__list_projects
+
+# List unresolved issues for a project
+mcp__bugsink__list_issues --project_id 1 --status unresolved
+
+# Get issue details
+mcp__bugsink__get_issue --issue_id <uuid>
+
+# Get stacktrace (pre-rendered Markdown)
+mcp__bugsink__get_stacktrace --event_id <uuid>
+
+# List events for an issue
+mcp__bugsink__list_events --issue_id <uuid>
+```
+
+**MCP Server Configuration**:
+
+Production (in `~/.claude/settings.json`):
+
+```json
+{
+  "bugsink": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "https://bugsink.projectium.com",
+      "BUGSINK_TOKEN": "<token>"
+    }
+  }
+}
+```
+
+Dev Container (in `.mcp.json`):
+
+```json
+{
+  "localerrors": {
+    "command": "node",
+    "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+    "env": {
+      "BUGSINK_URL": "http://127.0.0.1:8000",
+      "BUGSINK_TOKEN": "<token>"
+    }
+  }
+}
+```
+
+### Creating API Tokens
+
+Bugsink 2.0.11 does not have a UI for API tokens. Create via Django management command.
+
+**Production**:
+
+```bash
+ssh root@projectium.com "cd /opt/bugsink && bugsink-manage create_auth_token"
+```
+
+**Dev Container**:
+
+```bash
+MSYS_NO_PATHCONV=1 podman exec -e DATABASE_URL=postgresql://bugsink:bugsink_dev_password@postgres:5432/bugsink -e SECRET_KEY=dev-bugsink-secret-key-minimum-50-characters-for-security flyer-crawler-dev sh -c 'cd /opt/bugsink/conf && DJANGO_SETTINGS_MODULE=bugsink_conf PYTHONPATH=/opt/bugsink/conf:/opt/bugsink/lib/python3.10/site-packages /opt/bugsink/bin/python -m django create_auth_token'
+```
+
+The command outputs a 40-character hex token.
+
+### Interpreting Errors
+
+**Error Anatomy**:
+
+```
+TypeError: Cannot read properties of undefined (reading 'map')
+├── Exception Type: TypeError
+├── Message: Cannot read properties of undefined (reading 'map')
+├── Where: FlyerItemsList.tsx:45:23
+├── When: 2026-01-22T10:30:00.000Z
+├── Count: 12 occurrences
+└── Context:
+    ├── URL: GET /api/flyers/123/items
+    ├── User: user@example.com
+    └── Release: v0.12.5
+```
+
+**Common Error Patterns**:
+
+| Pattern                             | Likely Cause                                      | Investigation                                      |
+| ----------------------------------- | ------------------------------------------------- | -------------------------------------------------- |
+| `TypeError: ... undefined`          | Missing null check, API returned unexpected shape | Check API response, add defensive coding           |
+| `DatabaseError: Connection timeout` | Pool exhaustion, slow queries                     | Check `/api/health/db-pool`, review slow query log |
+| `RedisConnectionError`              | Redis unavailable                                 | Check Redis service, network connectivity          |
+| `ValidationError: ...`              | Invalid input, schema mismatch                    | Review request payload, update validation          |
+| `NotFoundError: ...`                | Missing resource                                  | Verify resource exists, check ID format            |
+
+### Error Triage Workflow
+
+1. **Review new issues daily** in Bugsink
+2. **Categorize by severity**:
+   - **Critical**: Data corruption, security, payment failures
+   - **High**: Core feature broken for many users
+   - **Medium**: Feature degraded, workaround available
+   - **Low**: Minor UX issues, cosmetic bugs
+3. **Check occurrence count** - frequent errors need urgent attention
+4. **Review stack trace** - identify root cause
+5. **Check recent deployments** - did a release introduce this?
+6. **Create Gitea issue** if not auto-synced
+
+### Bugsink-to-Gitea Sync
+
+The test environment automatically syncs Bugsink issues to Gitea (see `docs/BUGSINK-SYNC.md`).
+
+**Sync Workflow**:
+
+1. Runs every 15 minutes on test server
+2. Fetches unresolved issues from all Bugsink projects
+3. Creates Gitea issues with appropriate labels
+4. Marks synced issues as resolved in Bugsink
+
+**Manual Sync**:
+
+```bash
+# Trigger sync via API (test environment only)
+curl -X POST https://flyer-crawler-test.projectium.com/api/admin/bugsink/sync \
+  -H "Authorization: Bearer <admin_jwt>"
+```
+
+---
+
+## Logstash Log Aggregation
+
+Logstash aggregates logs from multiple sources and forwards errors to Bugsink (ADR-050).
+
+### Architecture
+
+```
+Log Sources                    Logstash                  Outputs
+┌──────────────┐              ┌─────────────┐           ┌─────────────┐
+│ PostgreSQL   │──────────────│             │───────────│ Bugsink     │

+### Pipeline Status
+
+**Check Logstash Service**:
+
+```bash
+ssh root@projectium.com
+
+# Service status
+systemctl status logstash
+
+# Recent logs
+journalctl -u logstash -n 50 --no-pager
+

+
+## PM2 Process Monitoring
+
+PM2 manages the Node.js application processes in production.
+
+### Process Overview
+
+**Production Processes** (`ecosystem.config.cjs`):
+
+| Process Name                     | Script      | Purpose              | Instances          |
+| -------------------------------- | ----------- | -------------------- | ------------------ |
+| `flyer-crawler-api`              | `server.ts` | Express API server   | Cluster (max CPUs) |
+| `flyer-crawler-worker`           | `worker.ts` | BullMQ job processor | 1                  |
+| `flyer-crawler-analytics-worker` | `worker.ts` | Analytics jobs       | 1                  |
+
+**Test Processes** (`ecosystem-test.config.cjs`):
+
+| Process Name                          | Script      | Port | Instances     |
+| ------------------------------------- | ----------- | ---- | ------------- |
+| `flyer-crawler-api-test`              | `server.ts` | 3002 | 1 (fork mode) |
+| `flyer-crawler-worker-test`           | `worker.ts` | N/A  | 1             |
+| `flyer-crawler-analytics-worker-test` | `worker.ts` | N/A  | 1             |
+
+### Basic Commands

+```
+
+### Health Indicators
+
+**Healthy Process**:
+
+```
+┌─────────────────────┬────┬─────────┬─────────┬───────┬────────┬─────────┬──────────┐
+│ Name                │ id │ mode    │ status  │ cpu   │ mem    │ uptime  │ restarts │
+├─────────────────────┼────┼─────────┼─────────┼───────┼────────┼─────────┼──────────┤
+│ flyer-crawler-api   │ 0  │ cluster │ online  │ 0.5%  │ 150MB  │ 5d      │ 0        │
+│ flyer-crawler-api   │ 1  │ cluster │ online  │ 0.3%  │ 145MB  │ 5d      │ 0        │
+│ flyer-crawler-worker│ 2  │ fork    │ online  │ 0.1%  │ 200MB  │ 5d      │ 0        │
+└─────────────────────┴────┴─────────┴─────────┴───────┴────────┴─────────┴──────────┘
+```
+
+**Warning Signs**:
+
+- `status: errored` - Process crashed
+- High `restarts` count - Instability
+- High `mem` (>500MB for API, >1GB for workers) - Memory leak
+- Low `uptime` with high restarts - Repeated crashes
+
+### Log File Locations
+
+| Process                | stdout                                                      | stderr          |
+| ---------------------- | ----------------------------------------------------------- | --------------- |
+| `flyer-crawler-api`    | `/home/gitea-runner/.pm2/logs/flyer-crawler-api-out.log`    | `...-error.log` |
+| `flyer-crawler-worker` | `/home/gitea-runner/.pm2/logs/flyer-crawler-worker-out.log` | `...-error.log` |
+
+### Memory Management
+
+PM2 is configured to restart processes when they exceed memory limits:
+
+| Process          | Memory Limit | Action       |
+| ---------------- | ------------ | ------------ |
+| API              | 500MB        | Auto-restart |
+| Worker           | 1GB          | Auto-restart |
+| Analytics Worker | 1GB          | Auto-restart |
+
+**Check Memory Usage**:
+
+```bash
+pm2 show flyer-crawler-api | grep memory
+pm2 show flyer-crawler-worker | grep memory
+```
+
+### Restart Strategies
+
+PM2 uses exponential backoff for restarts:
+
+```javascript
+{
+  max_restarts: 40,
+  exp_backoff_restart_delay: 100,  // Start at 100ms, exponentially increase
+  min_uptime: '10s',  // Must run 10s to be considered "started"
+}
+```
+
+**Force Restart After Repeated Failures**:
+
+```bash
+pm2 delete flyer-crawler-api
+pm2 start ecosystem.config.cjs --only flyer-crawler-api
+```
+
+---
+
+## Database Monitoring
+
+### Connection Pool Status
+
+The application uses a PostgreSQL connection pool with these defaults:
+
+| Setting                   | Value | Purpose                          |
+| ------------------------- | ----- | -------------------------------- |
+| `max`                     | 20    | Maximum concurrent connections   |
+| `idleTimeoutMillis`       | 30000 | Close idle connections after 30s |
+| `connectionTimeoutMillis` | 2000  | Fail if connection takes >2s     |
+
+**Check Pool Status via API**:
+
+```bash
+curl -s https://flyer-crawler.projectium.com/api/health/db-pool | jq .
+
+# Response
+{
+  "success": true,
+  "data": {
+    "message": "Pool Status: 10 total, 8 idle, 0 waiting.",
+    "totalCount": 10,
+    "idleCount": 8,
+    "waitingCount": 0
+  }
+}
+```
+
+**Pool Health Thresholds**:
+
+| Metric              | Healthy | Warning | Critical   |
+| ------------------- | ------- | ------- | ---------- |
+| Waiting Connections | 0-2     | 3-4     | 5+         |
+| Total Connections   | 1-15    | 16-19   | 20 (maxed) |
+
+### Slow Query Logging
+
+PostgreSQL is configured to log slow queries:
+
+```ini
+# /etc/postgresql/14/main/conf.d/observability.conf
+log_min_duration_statement = 1000  # Log queries over 1 second
+```
+
+**View Slow Queries**:
+
+```bash
+ssh root@projectium.com
+grep "duration:" /var/log/postgresql/postgresql-$(date +%Y-%m-%d).log | tail -20
+```
+
+### Database Size Monitoring
+
+```bash
+# Connect to production database
+psql -h localhost -U flyer_crawler_prod -d flyer-crawler-prod
+
+# Database size
+SELECT pg_size_pretty(pg_database_size('flyer-crawler-prod'));
+
+# Table sizes
+SELECT
+  relname AS table,
+  pg_size_pretty(pg_total_relation_size(relid)) AS total_size,
+  pg_size_pretty(pg_relation_size(relid)) AS data_size,
+  pg_size_pretty(pg_indexes_size(relid)) AS index_size
+FROM pg_catalog.pg_statio_user_tables
+ORDER BY pg_total_relation_size(relid) DESC
+LIMIT 10;
+
+# Check for bloat
+SELECT schemaname, relname, n_dead_tup, n_live_tup,
+       round(n_dead_tup * 100.0 / nullif(n_live_tup + n_dead_tup, 0), 2) as dead_pct
+FROM pg_stat_user_tables
+WHERE n_dead_tup > 1000
+ORDER BY n_dead_tup DESC;
+```
+
+### Disk Space Monitoring
+
+```bash
+# Check PostgreSQL data directory
+du -sh /var/lib/postgresql/14/main/
+
+# Check available disk space
+df -h /var/lib/postgresql/
+
+# Estimate growth rate
+psql -c "SELECT date_trunc('day', created_at) as day, count(*)
+         FROM flyer_items
+         WHERE created_at > now() - interval '7 days'
+         GROUP BY 1 ORDER BY 1;"
+```
+
+### Database Health via MCP
+
+```bash
+# Query database directly
+mcp__devdb__query --sql "SELECT count(*) FROM flyers WHERE created_at > now() - interval '1 day'"
+
+# Check connection count
+mcp__devdb__query --sql "SELECT count(*) FROM pg_stat_activity WHERE datname = 'flyer_crawler_dev'"
+```
+
+---
+
+## Redis Monitoring
+
+### Basic Health Check
+
+```bash
+# Via API endpoint
+curl -s https://flyer-crawler.projectium.com/api/health/redis | jq .
+
+# Direct Redis check (on server)
+redis-cli ping  # Should return PONG
+```
+
+### Memory Usage
+
+```bash
+redis-cli info memory | grep -E "used_memory_human|maxmemory_human|mem_fragmentation_ratio"
+
+# Expected output
+used_memory_human:50.00M
+maxmemory_human:256.00M
+mem_fragmentation_ratio:1.05
+```
+
+**Memory Thresholds**:
+
+| Metric              | Healthy     | Warning | Critical |
+| ------------------- | ----------- | ------- | -------- |
+| Used Memory         | <70% of max | 70-85%  | >85%     |
+| Fragmentation Ratio | 1.0-1.5     | 1.5-2.0 | >2.0     |
+
+### Cache Statistics
+
+```bash
+redis-cli info stats | grep -E "keyspace_hits|keyspace_misses|evicted_keys"
+
+# Calculate hit rate
+# Hit Rate = keyspace_hits / (keyspace_hits + keyspace_misses) * 100
+```
+
+**Cache Hit Rate Targets**:
+
+- Excellent: >95%
+- Good: 85-95%
+- Needs attention: <85%
+
+### Queue Monitoring
+
+BullMQ queues are stored in Redis:
+
+```bash
+# List all queues
+redis-cli keys "bull:*:id"
+
+# Check queue depths
+redis-cli llen "bull:flyer-processing:wait"
+redis-cli llen "bull:email-sending:wait"
+redis-cli llen "bull:analytics-reporting:wait"
+
+# Check failed jobs
+redis-cli llen "bull:flyer-processing:failed"
+```
+
+**Queue Depth Thresholds**:
+
+| Queue               | Normal | Warning | Critical |
+| ------------------- | ------ | ------- | -------- |
+| flyer-processing    | 0-10   | 11-50   | >50      |
+| email-sending       | 0-100  | 101-500 | >500     |
+| analytics-reporting | 0-5    | 6-20    | >20      |
+
+### Bull Board UI
+
+Access the job queue dashboard:
+
+- **Production**: `https://flyer-crawler.projectium.com/api/admin/jobs` (requires admin auth)
+- **Test**: `https://flyer-crawler-test.projectium.com/api/admin/jobs`
+- **Dev**: `http://localhost:3001/api/admin/jobs`
+
+Features:
+
+- View all queues and job counts
+- Inspect job data and errors
+- Retry failed jobs
+- Clean completed jobs
+
+### Redis Database Allocation
+
+| Database | Purpose                  |
+| -------- | ------------------------ |
+| 0        | BullMQ production queues |
+| 1        | BullMQ test queues       |
+| 15       | Bugsink sync state       |
+
+---
+
+## Production Alerts and On-Call
+
+### Critical Monitoring Targets
+
+| Service    | Check               | Interval | Alert Threshold        |
+| ---------- | ------------------- | -------- | ---------------------- |
+| API Server | `/api/health/ready` | 1 min    | 2 consecutive failures |
+| Database   | Pool waiting count  | 1 min    | >5 waiting             |
+| Redis      | Memory usage        | 5 min    | >85% of maxmemory      |
+| Disk Space | `/var/log`          | 15 min   | <10GB free             |
+| Worker     | Queue depth         | 5 min    | >50 jobs waiting       |
+| Error Rate | Bugsink issue count | 15 min   | >10 new issues/hour    |
+
+### Alert Channels
+
+Configure alerts in your monitoring tool (UptimeRobot, Datadog, etc.):
+
+1. **Slack channel**: `#flyer-crawler-alerts`
+2. **Email**: On-call rotation email
+3. **PagerDuty**: Critical issues only
+
+### On-Call Response Procedures
+
+**P1 - Critical (Site Down)**:
+
+1. Acknowledge alert within 5 minutes
+2. Check `/api/health/ready` - identify failing service
+3. Check PM2 status: `pm2 list`
+4. Check recent deploys: `git log -5 --oneline`
+5. If database: check pool, restart if needed
+6. If Redis: check memory, flush if critical
+7. If application: restart PM2 processes
+8. Document in incident channel
+
+**P2 - High (Degraded Service)**:
+
+1. Acknowledge within 15 minutes
+2. Review Bugsink for error patterns
+3. Check system resources (CPU, memory, disk)
+4. Identify root cause
+5. Plan remediation
+6. Create Gitea issue if not auto-created
+
+**P3 - Medium (Non-Critical)**:
+
+1. Acknowledge within 1 hour
+2. Review during business hours
+3. Create Gitea issue for tracking
+
+### Quick Diagnostic Commands

+# Frontend Test Automation Plan
+
+**Date**: 2026-01-18
+**Status**: Awaiting Approval
+**Related**: [2026-01-18-frontend-tests.md](../tests/2026-01-18-frontend-tests.md)
+
+## Executive Summary
+
+This plan formalizes the automated testing of 35+ API endpoints manually tested on 2026-01-18. The testing covered 7 major areas including end-to-end user flows, edge cases, queue behavior, authentication, performance, real-time features, and data integrity.
+
+**Recommendation**: Most tests should be added as **integration tests** (Supertest-based), with select critical flows as **E2E tests**. This aligns with ADR-010 and ADR-040's guidance on testing economics.
+
+---
+
+## Analysis of Manual Tests vs Existing Coverage
+
+### Current Test Coverage
+
+| Test Type   | Existing Files | Existing Tests |
+| ----------- | -------------- | -------------- |

+
+---
+
+## Implementation Plan
+
+### Phase 1: New Integration Test Files (Priority: High)
+
+#### 1.1 Create `deals.integration.test.ts`
+
+**Rationale**: Routes were unmounted until this testing session; no tests exist.
+
+```typescript
+// Tests to add:
+describe('Deals API', () => {
+  it('GET /api/deals/best-watched-prices requires auth');
+  it('GET /api/deals/best-watched-prices returns watched items for user');
+  it('Returns empty array when no watched items');
+});
+```
+
+**Estimated effort**: 30 minutes
+
+#### 1.2 Create `reactions.integration.test.ts`
+
+**Rationale**: Routes were unmounted until this testing session; no tests exist.
+
+```typescript
+// Tests to add:
+describe('Reactions API', () => {
+  it('GET /api/reactions/summary/:targetType/:targetId returns counts');
+  it('POST /api/reactions/toggle requires auth');
+  it('POST /api/reactions/toggle toggles reaction on/off');
+  it('Returns validation error for invalid target_type');
+  it('Returns validation error for non-string entity_id');
+});
+```
+
+**Estimated effort**: 45 minutes
+
+#### 1.3 Create `edge-cases.integration.test.ts`
+
+**Rationale**: Consolidate edge case tests discovered during manual testing.
+
+```typescript
+// Tests to add:
+describe('Edge Cases', () => {
+  describe('File Upload Validation', () => {
+    it('Accepts small files');
+    it('Processes corrupt file with IMAGE_CONVERSION_FAILED');
+    it('Rejects wrong checksum format');
+    it('Rejects short checksum');
+  });
+
+  describe('Input Sanitization', () => {
+    it('Handles XSS payloads in shopping list names (stores as-is)');
+    it('Handles unicode/emoji in text fields');
+    it('Rejects null bytes in JSON');
+    it('Handles very long input strings');
+  });
+
+  describe('Authorization Boundaries', () => {
+    it('Cross-user access returns 404 (not 403)');
+    it('SQL injection in query params is safely handled');
+  });
+});
+```
+
+**Estimated effort**: 1.5 hours
+
+#### 1.4 Create `data-integrity.integration.test.ts`
+
+**Rationale**: Consolidate FK/cascade/constraint tests.
+
+```typescript
+// Tests to add:
+describe('Data Integrity', () => {
+  describe('Cascade Deletes', () => {
+    it('User deletion cascades to shopping lists, budgets, notifications');
+    it('Shopping list deletion cascades to items');
+    it('Admin cannot delete own account');

+
+  describe('Unique Constraints', () => {
+    it('Duplicate email returns CONFLICT');
+    it('Duplicate flyer checksum is handled');
+  });
+
+  describe('CHECK Constraints', () => {
+    it('Budget period rejects invalid values');
+    it('Budget amount rejects negative values');
+  });
+});
+```
+
+**Estimated effort**: 2 hours
+
+---
+
+### Phase 2: Extend Existing Integration Tests (Priority: Medium)
+
+#### 2.1 Extend `budget.integration.test.ts`
+
+Add validation edge cases discovered during manual testing:
+
+```typescript
+// Tests to add:
+it('Rejects period="yearly" (only weekly/monthly allowed)');
+it('Rejects negative amount_cents');
+it('Rejects invalid date format');
+it('Returns 404 for update on non-existent budget');
+it('Returns 404 for delete on non-existent budget');
+```
+
+**Estimated effort**: 30 minutes
+
+#### 2.2 Extend `admin.integration.test.ts`
+
+Add queue and trigger endpoint tests:
+
+```typescript
+// Tests to add:
+describe('Queue Management', () => {
+  it('GET /api/admin/queues/status returns all queue counts');
+  it('POST /api/admin/trigger/analytics-report enqueues job');
+  it('POST /api/admin/trigger/weekly-analytics enqueues job');
+  it('POST /api/admin/trigger/daily-deal-check enqueues job');
+  it('POST /api/admin/jobs/:queue/:id/retry retries failed job');
+  it('POST /api/admin/system/clear-cache clears Redis cache');
+  it('Returns validation error for invalid queue name');
+  it('Returns 404 for retry on non-existent job');
+});
+```
+
+**Estimated effort**: 1 hour
+
+#### 2.3 Extend `auth.integration.test.ts`
+
+Add token malformation edge cases:
+
+```typescript
+// Tests to add:
+describe('Token Edge Cases', () => {
+  it('Empty Bearer token returns Unauthorized');
+  it('Token without dots returns Unauthorized');
+  it('Token with 2 parts returns Unauthorized');
+  it('Token with invalid signature returns Unauthorized');
+  it('Lowercase "bearer" scheme is accepted');
+  it('Basic auth scheme returns Unauthorized');
+  it('Tampered token payload returns Unauthorized');
+});
+
+describe('Login Security', () => {
+  it('Wrong password and non-existent user return same error');
+  it('Forgot password returns same response for existing/non-existing');
+});
+```
+
+**Estimated effort**: 45 minutes
+
+#### 2.4 Extend `recipe.integration.test.ts`
+
+Add fork error case and comment tests:
+
+```typescript
+// Tests to add:
+it('Fork fails for seed recipes (null user_id)');
+it('POST /api/recipes/:id/comments adds comment');
+it('GET /api/recipes/:id/comments returns comments');
+```
+
+**Estimated effort**: 30 minutes
+
+#### 2.5 Extend `notification.integration.test.ts`
+
+Add job status polling tests:
+
+```typescript
+// Tests to add:
+describe('Job Status Polling', () => {
+  it('GET /api/ai/jobs/:id/status returns completed job');
+  it('GET /api/ai/jobs/:id/status returns failed job with error');
+  it('GET /api/ai/jobs/:id/status returns 404 for non-existent');
+  it('Job status endpoint works without auth (public)');
+});
+```
+
+**Estimated effort**: 30 minutes
+
+---
+
+### Phase 3: E2E Tests (Priority: Low-Medium)
+
+Per ADR-040, E2E tests should be limited to critical user flows. The existing E2E tests cover the main flows well. However, we should consider:
+
+#### 3.1 Do NOT Add
+
+- Performance tests (handle via monitoring, not E2E)
+- Pagination tests (integration level is sufficient)
+- Cache behavior tests (integration level is sufficient)
+
+#### 3.2 Consider Adding (Optional)
+
+**Budget flow E2E** - If budget management becomes a critical feature:
+
+```typescript
+// budget-journey.e2e.test.ts
+describe('Budget Journey', () => {
+  it('User creates budget → tracks spending → sees analysis');
+});
+```
+
+**Recommendation**: Defer unless budget becomes a core value proposition.
+
+---
+
+### Phase 4: Documentation Updates
+
+#### 4.1 Update ADR-010
+
+Add the newly discovered API gotchas to the testing documentation:
+
+- `entity_id` must be STRING in reactions
+- `customItemName` (camelCase) in shopping list items
+- `scan_source` must be `manual_entry`, not `manual`
+
+#### 4.2 Update CLAUDE.md
+
+Add API reference section for correct endpoint calls (already captured in test doc).
+
+---
+
+## Tests NOT Recommended
+
+Per ADR-040 (Testing Economics), the following tests from the manual session should NOT be automated:
+
+| Test Area                   | Reason                                            |
+| --------------------------- | ------------------------------------------------- |
+| Performance benchmarks      | Use APM/monitoring tools instead (see ADR-015)    |
+| Concurrent request handling | Connection pool behavior is framework-level       |
+| Cache hit/miss timing       | Observable via Redis metrics, not test assertions |
+| Response time consistency   | Better suited for production monitoring           |
+| WebSocket/SSE               | Not implemented - polling is the architecture     |
+
+---
+
+## Implementation Timeline
+
+| Phase     | Description                    | Effort       | Priority |
+| --------- | ------------------------------ | ------------ | -------- |
+| 1.1       | deals.integration.test.ts      | 30 min       | High     |
+| 1.2       | reactions.integration.test.ts  | 45 min       | High     |
+| 1.3       | edge-cases.integration.test.ts | 1.5 hours    | High     |
+| 1.4       | data-integrity.integration.ts  | 2 hours      | High     |
+| 2.1       | Extend budget tests            | 30 min       | Medium   |
+| 2.2       | Extend admin tests             | 1 hour       | Medium   |
+| 2.3       | Extend auth tests              | 45 min       | Medium   |
+| 2.4       | Extend recipe tests            | 30 min       | Medium   |
+| 2.5       | Extend notification tests      | 30 min       | Medium   |
+| 4.x       | Documentation updates          | 30 min       | Low      |
+| **Total** |                                | **~8 hours** |          |
+
+---
+
+## Verification Strategy
+
+For each new test file, verify by running:
+
+```bash
+# In dev container
+npm run test:integration -- --run src/tests/integration/<file>.test.ts
+```
+
+All tests should:
+
+1. Pass consistently (no flaky tests)
+2. Run in isolation (no shared state)
+3. Clean up test data (use `cleanupDb()`)
+4. Follow existing patterns in the codebase
+
+---
+
+## Risks and Mitigations
+
+| Risk                                 | Mitigation                                          |
+| ------------------------------------ | --------------------------------------------------- |
+| Test flakiness from async operations | Use proper waitFor/polling utilities                |
+| Database state leakage between tests | Strict cleanup in afterEach/afterAll                |
+| Queue state affecting test isolation | Drain/pause queues in tests that interact with them |
+| Port conflicts                       | Use dedicated test port (3099)                      |
+
+---
+
+## Approval Request
+
+Please review and approve this plan. Upon approval, implementation will proceed in priority order (Phase 1 first).
+
+**Questions for clarification**:
+
+1. Should the deals/reactions routes remain mounted, or was that a temporary fix?
+2. Is the recipe fork failure for seed recipes expected behavior or a bug to fix?
+3. Any preference on splitting Phase 1 into multiple PRs vs one large PR?

+
+## Example Requests
+
+### Debugging Extraction Failures
+
+```
+"Use ai-usage to debug why flyer extractions are failing for
+multi-page PDFs. The error logs show 'Invalid JSON response'
+but only for certain stores."
+```
+
+### Optimizing Prompts
+
+```
+"Use ai-usage to improve the item extraction prompt. Currently
+it's missing unit prices when items show 'X for $Y' pricing
+(e.g., '3 for $5')."
+```
+
+### Handling Rate Limits
+
+```
+"Use ai-usage to implement exponential backoff for Gemini API
+rate limits. We're seeing 429 errors during high-volume uploads."
+```
+
+### Adding New AI Features
+
+```
+"Use ai-usage to add a feature that uses Gemini to categorize
+extracted items into grocery categories (produce, dairy, meat, etc.)."
+```
+
+## Extraction Pipeline
+
+### 1. Image Preprocessing
+
+```typescript
+// Convert PDF to images, resize large images
+const processedImages = await imageProcessor.prepareForAI(uploadedFile);
+```
+
+### 2. Prompt Construction
+
+The extraction prompt includes:
+
+- System instructions for the AI model
+- Expected output schema (JSON)
+- Examples of correct extraction
+- Handling instructions for edge cases
+
+### 3. API Call
+
+```typescript
+const response = await aiService.extractFlyerData(processedImages, storeContext, extractionOptions);
+```
+
+### 4. Response Validation
+
+```typescript
+// Validate against Zod schema
+const validatedItems = flyerItemsSchema.parse(response.items);
+```
+
+### 5. Normalization
+
+```typescript
+// Normalize prices, units, quantities
+const normalizedItems = normalizeExtractedItems(validatedItems);
+```
+
+## Common Issues and Solutions
+
+### Issue: Inconsistent Price Extraction
+
+**Symptoms**: Same item priced differently on different extractions.
+
+**Solution**: Improve prompt with explicit price format examples:
+
+```
+"Price formats to recognize:
+- $X.XX (regular price)
+- X for $Y.YY (multi-buy)
+- $X.XX/lb or $X.XX/kg (unit price)
+- $X.XX each (per item)
+- SAVE $X.XX (discount amount, not item price)"
+```
+
+### Issue: Missing Items from Dense Flyers
+
+**Symptoms**: Flyers with many items on one page have missing extractions.
+
+**Solution**:
+
+1. Split page into quadrants for separate extraction
+2. Increase token limit for response
+3. Use structured grid-based prompting
+
+### Issue: Rate Limit Errors (429)
+
+**Symptoms**: `429 Too Many Requests` errors during bulk uploads.
+
+**Solution**: Implement request queuing:
+
+```typescript
+// Add to job queue instead of direct call
+await flyerQueue.add(
+  'extract',
+  {
+    flyerId,
+    images,
+  },
+  {
+    attempts: 3,
+    backoff: {
+      type: 'exponential',
+      delay: 2000,
+    },
+  },
+);
+```
+
+### Issue: Hallucinated Items
+
+**Symptoms**: Items extracted that don't exist in the flyer.
+
+**Solution**:
+
+1. Add confidence scoring to extraction
+2. Request bounding box coordinates for verification
+3. Add post-extraction validation against image
+
+## Prompt Engineering Best Practices
+
+### 1. Be Specific About Output Format
+
+```
+Output MUST be valid JSON matching this schema:
+{
+  "items": [
+    {
+      "name": "string (product name as shown)",
+      "brand": "string or null",
+      "price": number (in dollars),
+      "unit": "string (each, lb, kg, etc.)",
+      "quantity": number (default 1)
+    }
+  ]
+}
+```
+
+### 2. Provide Examples
+
+```
+Example extractions:
+- "Chicken Breast $4.99/lb" -> {"name": "Chicken Breast", "price": 4.99, "unit": "lb"}
+- "Coca-Cola 12pk $5.99" -> {"name": "Coca-Cola", "quantity": 12, "price": 5.99, "unit": "each"}
+```
+
+### 3. Handle Edge Cases Explicitly
+
+```
+Special cases:
+- If "LIMIT X" shown, add to notes, don't affect price
+- If "SAVE $X" shown without base price, mark price as null
+- If item is "FREE with purchase", set price to 0
+```
+
+### 4. Request Structured Thinking
+
+```
+For each item:
+1. Identify the product name and brand
+2. Find the associated price
+3. Determine if price is per-unit or total
+4. Extract any quantity information
+```
+
+## Monitoring AI Performance
+
+### Metrics to Track
+
+| Metric                  | Description                             | Target          |
+| ----------------------- | --------------------------------------- | --------------- |
+| Extraction success rate | % of flyers processed without error     | >95%            |
+| Items per flyer         | Average items extracted                 | Varies by store |
+| Price accuracy          | Match rate vs manual verification       | >98%            |
+| Response time           | Time from upload to extraction complete | <30s            |
+
+### Logging
+
+```typescript
+log.info(
+  {
+    flyerId,
+    itemCount: extractedItems.length,
+    processingTime: duration,
+    modelVersion: response.model,
+    tokenUsage: response.usage,
+  },
+  'Flyer extraction completed',
+);
+```
+
+## Environment Configuration
+
+| Variable                         | Purpose                     |
+| -------------------------------- | --------------------------- |
+| `VITE_GOOGLE_GENAI_API_KEY`      | Gemini API key (production) |
+| `VITE_GOOGLE_GENAI_API_KEY_TEST` | Gemini API key (test)       |
+
+**Note**: Use separate API keys for production and test to avoid rate limit conflicts and enable separate billing tracking.
+
+## Testing AI Features
+
+### Unit Tests
+
+Mock the Gemini API response:
+
+```typescript
+vi.mock('@google/generative-ai', () => ({
+  GoogleGenerativeAI: vi.fn().mockImplementation(() => ({
+    getGenerativeModel: () => ({
+      generateContent: vi.fn().mockResolvedValue({
+        response: {
+          text: () => JSON.stringify({ items: mockItems }),
+        },
+      }),
+    }),
+  })),
+}));
+```
+
+### Integration Tests
+
+Use recorded responses for deterministic testing:
+
+```typescript
+// Save real API responses to fixtures
+const fixtureResponse = await fs.readFile('fixtures/gemini-response.json');
+```
