- Added tiered logging and error handling in various PostgreSQL functions to improve observability and error tracking.
- Updated E2E tests to reflect changes in API endpoints for fetching best watched prices.
- Introduced a comprehensive troubleshooting runbook for Logstash to assist in diagnosing common issues in the PostgreSQL observability pipeline.

+# 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": {

+### 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`**
+
+## Quick Reference: Available MCP Servers
+
+| Server              | Package/Repo                                       | Purpose                     |

+| bugsink             | `j-shelfwood/bugsink-mcp` (build from source)      | Error tracking for Bugsink  |
+| sentry              | `@sentry/mcp-server`                               | Error tracking for Sentry   |
+| playwright          | `@anthropics/mcp-server-playwright`                | Browser automation          |
+
+## 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

 # Claude Code Project Instructions
 
+## 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
+
+---
+
+## Project Instructions
+
+### Things to Remember
+
+Before writing any code:
+
+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.**
+

+### 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;

+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"

+
+## 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

+# Store Address Implementation - Progress Status
+
+## ✅ COMPLETED (Core Foundation)
+
+### Phase 1: Database Layer (100%)
+
+- ✅ **StoreRepository** ([src/services/db/store.db.ts](src/services/db/store.db.ts))
+  - `createStore()`, `getStoreById()`, `getAllStores()`, `updateStore()`, `deleteStore()`, `searchStoresByName()`
+  - Full test coverage: [src/services/db/store.db.test.ts](src/services/db/store.db.test.ts)
+
+- ✅ **StoreLocationRepository** ([src/services/db/storeLocation.db.ts](src/services/db/storeLocation.db.ts))
+  - `createStoreLocation()`, `getLocationsByStoreId()`, `getStoreWithLocations()`, `getAllStoresWithLocations()`, `deleteStoreLocation()`, `updateStoreLocation()`
+  - Full test coverage: [src/services/db/storeLocation.db.test.ts](src/services/db/storeLocation.db.test.ts)
+
+- ✅ **Enhanced AddressRepository** ([src/services/db/address.db.ts](src/services/db/address.db.ts))
+  - Added: `searchAddressesByText()`, `getAddressesByStoreId()`
+
+### Phase 2: TypeScript Types (100%)
+
+- ✅ Added to [src/types.ts](src/types.ts):
+  - `StoreLocationWithAddress` - Store location with full address data
+  - `StoreWithLocations` - Store with all its locations
+  - `CreateStoreRequest` - API request type for creating stores
+
+### Phase 3: API Routes (100%)
+
+- ✅ **store.routes.ts** ([src/routes/store.routes.ts](src/routes/store.routes.ts))
+  - GET /api/stores (list with optional ?includeLocations=true)
+  - GET /api/stores/:id (single store with locations)
+  - POST /api/stores (create with optional address)
+  - PUT /api/stores/:id (update store)
+  - DELETE /api/stores/:id (admin only)
+  - POST /api/stores/:id/locations (add location)
+  - DELETE /api/stores/:id/locations/:locationId
+- ✅ **store.routes.test.ts** ([src/routes/store.routes.test.ts](src/routes/store.routes.test.ts))
+  - Full test coverage for all endpoints
+- ✅ **server.ts** - Route registered at /api/stores
+
+### Phase 4: Database Query Updates (100% - COMPLETE)
+
+- ✅ **admin.db.ts** ([src/services/db/admin.db.ts](src/services/db/admin.db.ts))
+  - Updated `getUnmatchedFlyerItems()` to include store with locations array
+  - Updated `getFlyersForReview()` to include store with locations array
+- ✅ **flyer.db.ts** ([src/services/db/flyer.db.ts](src/services/db/flyer.db.ts))
+  - Updated `getFlyers()` to include store with locations array
+  - Updated `getFlyerById()` to include store with locations array
+- ✅ **deals.db.ts** ([src/services/db/deals.db.ts](src/services/db/deals.db.ts))
+  - Updated `findBestPricesForWatchedItems()` to include store with locations array
+- ✅ **types.ts** - Updated `WatchedItemDeal` interface to use store object instead of store_name
+
+### Phase 6: Integration Test Updates (100% - ALL COMPLETE)
+
+- ✅ **admin.integration.test.ts** - Updated to use `createStoreWithLocation()`
+- ✅ **flyer.integration.test.ts** - Updated to use `createStoreWithLocation()`
+- ✅ **price.integration.test.ts** - Updated to use `createStoreWithLocation()`
+- ✅ **public.routes.integration.test.ts** - Updated to use `createStoreWithLocation()`
+- ✅ **receipt.integration.test.ts** - Updated to use `createStoreWithLocation()`
+
+### Test Helpers
+
+- ✅ **storeHelpers.ts** ([src/tests/utils/storeHelpers.ts](src/tests/utils/storeHelpers.ts))
+  - `createStoreWithLocation()` - Creates normalized store+address+location
+  - `cleanupStoreLocations()` - Bulk cleanup

+### Phase 7: Mock Factories (100% - COMPLETE)
+
+- ✅ **mockFactories.ts** ([src/tests/utils/mockFactories.ts](src/tests/utils/mockFactories.ts))
+  - Added `createMockStoreLocation()` - Basic store location mock

+  - Added `createMockStoreWithLocations()` - Full store with array of locations
+
+### Phase 8: Schema Migration (100% - COMPLETE)
+
+- ✅ **Architectural Decision**: Made addresses **optional** by design
+  - Stores can exist without any locations
+  - No data migration required
+  - No breaking changes to existing code
+  - Addresses can be added incrementally
+- ✅ **Implementation Details**:
+  - API accepts `address` as optional field in POST /api/stores
+  - Database queries use `LEFT JOIN` for locations (not `INNER JOIN`)
+  - Frontend shows "No location data" when store has no addresses
+  - All existing stores continue to work without modification
+
+### Phase 9: Cache Invalidation (100% - COMPLETE)

+
+### Phase 5: Frontend Components (100% - COMPLETE)
+

+  - Added 7 API client functions: `getStores()`, `getStoreById()`, `createStore()`, `updateStore()`, `deleteStore()`, `addStoreLocation()`, `deleteStoreLocation()`
+- ✅ **AdminStoreManager** ([src/pages/admin/components/AdminStoreManager.tsx](src/pages/admin/components/AdminStoreManager.tsx))
+  - Table listing all stores with locations
+  - Create/Edit/Delete functionality with modal forms

+
+## 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)
+
+---
+
+### Phase 9: Documentation & Cache Invalidation
+
+#### 9.1 Update API Documentation
+
+- Add store endpoints to API docs
+- Document request/response formats
+- Add examples
+
+#### 9.2 Cache Invalidation
+
+[src/services/cacheService.server.ts](src/services/cacheService.server.ts):
+
+- Add `invalidateStores()` method
+- Add `invalidateStoreLocations(storeId)` method
+- Call after create/update/delete operations
+
+---
+

+11. `src/features/store/LocationSelector.tsx` - Location picker
+12. `STORE_ADDRESS_IMPLEMENTATION_PLAN.md` - This document
+
+### Files to Modify (20+ files):
+
+**Database Layer (3)**:
+
+- `src/services/db/address.db.ts` - Add search functions
+- `src/services/db/admin.db.ts` - Update JOINs
+- `src/services/db/flyer.db.ts` - Update JOINs
+- `src/services/db/deals.db.ts` - Update queries
+- `src/services/db/receipt.db.ts` - Update queries
+
+**API Routes (3)**:
+
+- `src/routes/flyer.routes.ts` - Include address in responses
+- `src/routes/deals.routes.ts` - Include address in responses
+- `src/routes/receipt.routes.ts` - Include address in responses
+
+**Types (1)**:
+
+- `src/types.ts` - Add StoreWithLocation and CreateStoreRequest types
+
+**Tests (10+)**:
+
+- `src/tests/integration/admin.integration.test.ts`
+- `src/tests/integration/flyer.integration.test.ts`
+- `src/tests/integration/price.integration.test.ts`
+- `src/tests/integration/public.routes.integration.test.ts`
+- `src/tests/integration/receipt.integration.test.ts`
+- `src/tests/utils/mockFactories.ts`
+- `src/features/flyer/FlyerDisplay.test.tsx`
+- `src/features/flyer/FlyerList.test.tsx`
+- Component tests for new store UI
+
+**Frontend (2+)**:
+
+- `src/pages/admin/Dashboard.tsx` - Add store management link
+- 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?
+
+---
+

+## PostgreSQL Function Observability (ADR-050)
+
+PostgreSQL function observability provides structured logging and error tracking for database functions, preventing silent failures. This setup forwards database errors to Bugsink for centralized monitoring.
+
+See [ADR-050](adr/0050-postgresql-function-observability.md) for the full architecture decision.
+
+### Prerequisites
+
+- PostgreSQL 14+ installed and running
+- Logstash installed and configured (see [Logstash section](#logstash-log-aggregation) above)
+- Bugsink running at `https://bugsink.projectium.com`
+
+### Step 1: Configure PostgreSQL Logging
+
+Create the observability configuration file:
+
+```bash
+sudo nano /etc/postgresql/14/main/conf.d/observability.conf
+```
+
+Add the following content:
+
+```ini
+# PostgreSQL Logging Configuration for Database Function Observability (ADR-050)
+
+# Enable logging to files for Logstash pickup
+logging_collector = on
+log_destination = 'stderr'
+log_directory = '/var/log/postgresql'
+log_filename = 'postgresql-%Y-%m-%d.log'
+log_rotation_age = 1d
+log_rotation_size = 100MB
+log_truncate_on_rotation = on
+
+# Log level - capture NOTICE and above (includes fn_log WARNING/ERROR)
+log_min_messages = notice
+client_min_messages = notice
+
+# Include useful context in log prefix
+log_line_prefix = '%t [%p] %u@%d '
+
+# Capture slow queries from functions (1 second threshold)
+log_min_duration_statement = 1000
+
+# Log statement types (off for production)
+log_statement = 'none'
+
+# Connection logging (off for production to reduce noise)
+log_connections = off
+log_disconnections = off
+```
+
+Set up the log directory:
+
+```bash
+# Create log directory
+sudo mkdir -p /var/log/postgresql
+
+# Set ownership to postgres user
+sudo chown postgres:postgres /var/log/postgresql
+sudo chmod 750 /var/log/postgresql
+```
+
+Restart PostgreSQL:
+
+```bash
+sudo systemctl restart postgresql
+```
+
+Verify logging is working:
+
+```bash
+# Check that log files are being created
+ls -la /var/log/postgresql/
+
+# Should see files like: postgresql-2026-01-20.log
+```
+
+### Step 2: Configure Logstash for PostgreSQL Logs
+
+The Logstash configuration is located at `/etc/logstash/conf.d/bugsink.conf`.
+
+**Key features:**
+
+- Parses PostgreSQL log format with grok patterns
+- Extracts JSON from `fn_log()` function calls
+- Tags WARNING/ERROR level logs
+- Routes production database errors to Bugsink project 1
+- Routes test database errors to Bugsink project 3
+- Transforms events to Sentry-compatible format
+
+**Configuration file:** `/etc/logstash/conf.d/bugsink.conf`
+
+See the [Logstash Configuration Reference](#logstash-configuration-reference) below for the complete configuration.
+
+**Grant Logstash access to PostgreSQL logs:**
+
+```bash
+# Add logstash user to postgres group
+sudo usermod -aG postgres logstash
+
+# Verify group membership
+groups logstash
+
+# Restart Logstash to apply changes
+sudo systemctl restart logstash
+```
+
+### Step 3: Test the Pipeline
+
+Test structured logging from PostgreSQL:
+
+```bash
+# Production database (routes to Bugsink project 1)
+sudo -u postgres psql -d flyer-crawler-prod -c "SELECT fn_log('WARNING', 'test_observability', 'Testing PostgreSQL observability pipeline', '{\"environment\": \"production\"}'::jsonb);"
+
+# Test database (routes to Bugsink project 3)
+sudo -u postgres psql -d flyer-crawler-test -c "SELECT fn_log('WARNING', 'test_observability', 'Testing PostgreSQL observability pipeline', '{\"environment\": \"test\"}'::jsonb);"
+```
+
+Check Bugsink UI:
+
+- Production errors: <https://bugsink.projectium.com> → Project 1 (flyer-crawler-backend)
+- Test errors: <https://bugsink.projectium.com> → Project 3 (flyer-crawler-backend-test)
+
+### Step 4: Verify Database Functions
+
+The following critical functions use `fn_log()` for observability:
+
+| Function                   | What it logs                             |
+| -------------------------- | ---------------------------------------- |
+| `award_achievement()`      | Missing achievements, duplicate awards   |
+| `fork_recipe()`            | Missing original recipes                 |
+| `handle_new_user()`        | User creation events                     |
+| `approve_correction()`     | Permission denied, corrections not found |
+| `complete_shopping_list()` | Permission checks, list not found        |
+
+Test error logging with a database function:
+
+```bash
+# Try to award a non-existent achievement (should fail and log to Bugsink)
+sudo -u postgres psql -d flyer-crawler-test -c "SELECT award_achievement('00000000-0000-0000-0000-000000000000'::uuid, 'NonexistentBadge');"
+
+# Check Bugsink project 3 - should see an ERROR with full context
+```

+    }
+  }
+}
+```
+
+**Setup Instructions:**
+
+1. Create log output directory:
+
+   ```bash
+   sudo mkdir -p /var/log/logstash
+   sudo chown logstash:logstash /var/log/logstash
+   ```
+
+2. Configure logrotate for Logstash file outputs:
+
+   ```bash
+   sudo tee /etc/logrotate.d/logstash <<EOF
+   /var/log/logstash/*.log {
+       daily
+       rotate 30
+       compress
+       delaycompress
+       missingok
+       notifempty
+       create 0644 logstash logstash
+   }
+   EOF
+   ```
+
+3. Verify Logstash can read PM2 logs:
+
+   ```bash
+   # Add logstash to required groups
+   sudo usermod -a -G postgres logstash
+   sudo usermod -a -G adm logstash
+
+   # Test permissions
+   sudo -u logstash cat /home/gitea-runner/.pm2/logs/flyer-crawler-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
+   ```
+
+4. Restart Logstash:
+
+   ```bash
+   sudo systemctl restart logstash
+   ```
+
+**Verification:**
+
+```bash
+# Check Logstash is processing new log sources
+curl -s http://localhost:9600/_node/stats/pipelines?pretty | jq '.pipelines.main.events'
+
+# Check file outputs
+ls -lh /var/log/logstash/
+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
+```

+# 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
+
+```

+## Environment Variables
+
+Add these to **test environment only** (`deploy-to-test.yml`):
+
+```bash
+# Bugsink API
+BUGSINK_URL=https://bugsink.projectium.com
+BUGSINK_API_TOKEN=<from Bugsink Settings > API Keys>
+
+# Gitea API
+GITEA_URL=https://gitea.projectium.com

+
+## Redis Configuration
+
+| Database | Purpose                  |
+| -------- | ------------------------ |
+| 0        | BullMQ production queues |
+| 1        | BullMQ test queues       |
+| 15       | Bugsink sync state       |
+
+**Key Pattern:**
+
+```
+bugsink:synced:{issue_uuid}
+```
+
+**Value (JSON):**
+
+```json
+{
+  "gitea_issue_number": 42,
+  "synced_at": "2026-01-17T10:30:00Z",

+  "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
+4. **Create**: Create Gitea issue with labels and full context
+5. **Record**: Store sync mapping in Redis db 15
+6. **Resolve**: Mark issue as resolved in Bugsink
+
+## Issue Template
+
+Created Gitea issues follow this format:
+
+```markdown
+## Error Details
+
+| Field        | Value                   |

+## Implementation Phases
+
+### Phase 1: Core Infrastructure
+
+- [ ] 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
+- [ ] Update deploy-to-test.yml
+- [ ] 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

+# 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)

+# 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`
+

+# 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
+```
+

+# 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
+
+---
+
+## Summary Table
+
+| Table                 | Foreign Key                 | Should Use                            | Status          | Priority |
+| --------------------- | --------------------------- | ------------------------------------- | --------------- | -------- |
+| **flyer_locations**   | flyer_id, store_location_id | Many-to-many link                     | ✅ **FIXED**    | ✅ Done  |
+| flyers                | store_id                    | ~~store_id~~ Now uses flyer_locations | ✅ **FIXED**    | ✅ Done  |
+| user_submitted_prices | store_id                    | store_location_id                     | ✅ **MIGRATED** | ✅ Done  |
+| receipts              | store_id                    | store_location_id                     | ✅ **MIGRATED** | ✅ Done  |
+| item_price_history    | store_location_id           | ✅ Already correct                    | ✅ Correct      | ✅ Good  |
+| shopping_trips        | (no store ref)              | N/A                                   | ✅ Correct      | ✅ Good  |
+| store_locations       | store_id, address_id        | ✅ Already correct                    | ✅ Correct      | ✅ Good  |

+
+## 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"
+```

+# 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' } }],
+});
+```
+
+## 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

+**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
+**Files Created**: 9 new files
+**Files Modified**: 11 existing files
+**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 `react-joyride`:
+
+**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
+- Persists completion in localStorage (`flyer_crawler_onboarding_completed`)
+- Skip button for experienced users
+- Progress indicator showing current step
+- Styled with brand colors (#14b8a6)
+- Dark mode compatible
+
+### Deliverables
+
+- **Created**: `src/hooks/useOnboardingTour.ts` (custom hook)
+- **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 Joyride component
+- **Installed**: `react-joyride@2.9.3`, `@types/react-joyride@2.0.2`
+
+### 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

+# 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`

+```
+
+## 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:**

+- `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
+
+See [src/tests/integration/websocket.integration.test.ts](../src/tests/integration/websocket.integration.test.ts) for comprehensive integration tests.

 **Date**: 2025-12-12
 
-**Status**: Proposed
+**Status**: Accepted
+
+**Implemented**: 2026-01-19
 
 ## 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

+
+## 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.
+### Positive
-**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.
+
+- **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
+
+Located in `src/services/websocketService.server.test.ts`:
+
+```typescript
+describe('WebSocketService', () => {
+  it('should initialize without errors', () => { ... });
+  it('should handle broadcasting with no active connections', () => { ... });
+  it('should shutdown gracefully', () => { ... });
+});
+```
+
+Located in `src/types/websocket.test.ts`:
+
+```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
+- Verify authentication and message routing
+- Test reconnection logic
+- Validate message delivery

+# 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',
+    },
+  },
+];
+```
+
+## Affected Areas
+
+### Immediate Violations (Must Fix)
+
+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-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

+
+---
+
+**Bugsink Issue**: {bugsink_url}
+**Project**: {project_slug}
+**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) |
+
+## Admin Interface
+
+### Manual Sync Endpoint
+
+```
+POST /api/admin/bugsink/sync
+Authorization: Bearer {admin_jwt}
+
+Response:
+{
+  "success": true,
+  "data": {
+    "synced": 3,
+    "skipped": 12,
+    "failed": 0,
+    "duration_ms": 2340
+  }
+}
+```
+
+### Sync Status Endpoint
+
+```
+GET /api/admin/bugsink/sync/status
+Authorization: Bearer {admin_jwt}
+
+Response:
+{
+  "success": true,
+  "data": {
+    "enabled": true,
+    "last_run": "2026-01-17T10:30:00Z",
+    "next_run": "2026-01-17T10:45:00Z",
+    "total_synced": 47,
+    "projects": [
+      { "slug": "flyer-crawler-backend", "synced_count": 12 },
+      ...
+    ]
+  }
+}
+```
+
+## 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

+# 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.

+
+---
+
+## 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('FK Constraints', () => {
+    it('Rejects invalid FK references via API');
+    it('Rejects invalid FK references via direct DB');
+  });
+
+  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     |
+
+---

+
+## 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?

+# 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?

+What is the correct named pipe address for Podman on Windows if it's not using the default docker_engine pipe?
+
+How do I configure the chrome-devtools-mcp server to connect to an existing Chrome instance using the browser_url input?
+
+
+Unused Input: The browser_url input is defined but not used in any server arguments. If you intend to connect chrome-devtools-mcp to an existing Chrome instance, you would typically pass that URL in the arguments instead of launching a new headless instance.
+
+
+
+
+
+Based on your current configuration and project setup (Gitea, Podman, PostgreSQL, Redis), here are several other valuable MCP servers available for VS Code.
+
+Recommended for Your Stack
+Since you are running a PostgreSQL and Redis stack via Podman, these servers would be immediately useful:
+
+PostgreSQL (@modelcontextprotocol/server-postgres)
+
+Purpose: Allows the AI to query your database directly (inspect schemas, run SELECT queries) without needing to shell into the container.
+Config:
+json
+"postgres": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://postgres:postgres@localhost:5432/flyer_crawler_dev"]
+}
+
+
+
+Redis (@modelcontextprotocol/server-redis)
+
+Purpose: Inspect and modify keys in your Redis instance.
+Config:
+json
+"redis": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-redis", "redis://localhost:6379"]
+}
+General Utility Servers
+These servers enhance the AI's core capabilities regardless of the specific project:
+
+
+Memory (@modelcontextprotocol/server-memory)
+
+Purpose: Gives the AI a persistent "knowledge graph" to remember context, user preferences, and project details across different chat sessions.
+Config:
+json
+"memory": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-memory"]
+}
+
+
+Brave Search (@modelcontextprotocol/server-brave-search)
+
+Purpose: Performs actual web searches (finding current docs, libraries, or solutions) rather than just fetching specific URLs like the fetch server does.
+Config:
+json
+ Show full code block 
+"brave-search": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-brave-search"],
+  "env": {
+    "BRAVE_API_KEY": "YOUR_API_KEY_HERE"
+  }
+}
+
+
+Sequential Thinking (@modelcontextprotocol/server-sequential-thinking)
+
+Purpose: A tool that helps the AI break down complex problems into step-by-step thought processes. It is particularly useful for debugging difficult logic or architectural planning.
+Config:
+json
+"sequential-thinking": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
+}
+
+
+Other Popular Servers
+
+GitHub: (@modelcontextprotocol/server-github) - If you ever need to interact with GitHub.com in addition to Gitea.
+
+Google Drive: (@modelcontextprotocol/server-google-drive) - Access files in Google Drive.
+
+Slack: (@modelcontextprotocol/server-slack) - Read and send Slack messages.
+
+Sentry: (@modelcontextprotocol/server-sentry) - Analyze error reports directly from Sentry.
+
+How to Find More
+The community maintains a comprehensive list of servers in the Awesome MCP Servers repository. You can find servers for almost any major tool (AWS, Azure, Linear, Jira, etc.).
+
+To add any of these, you simply add a new entry to the mcpServers object in your mcp.json file, similar to how you configured podman or fetch.
+
+
+
+
+
+
+Create a new ADR for "Worker Health Checks" to monitor stalled background jobs.

+-- Migration 007: Fix trigger log levels for expected edge cases
+-- Date: 2026-01-21
+-- Issues:
+--   - Bugsink issue 0e1d3dfd-c935-4b0c-aaea-60aa2364e0cd (flyer not found during CASCADE delete)
+--   - Bugsink issue 150e86fa-b197-465b-9cbe-63663c63788e (missing validity dates)
+-- Problem 1: When a flyer is deleted with ON DELETE CASCADE, the flyer_items trigger
+--            tries to update the already-deleted flyer, logging ERROR messages.
+-- Solution 1: Change log level from ERROR to INFO since this is expected behavior.
+-- Problem 2: When a flyer_item is inserted for a flyer with NULL validity dates,
+--            the price history trigger logs ERROR even though it handles it gracefully.
+-- Solution 2: Change log level from ERROR to WARNING since the trigger degrades gracefully.
+
+-- Drop and recreate the trigger function with updated log level
