ci: Bump version to 0.10.0 for production release [skip ci]

Allows test environment PM2 processes to load environment variables
from /var/www/flyer-crawler-test.projectium.com/.env file, enabling
manual restarts without requiring CI/CD to inject variables.

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

+| 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`**
+

+| 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
+
 ## Communication Style: Ask Before Assuming

+## Database Schema Files
+
+**CRITICAL**: The database schema files must be kept in sync with each other. When making schema changes:
+
+| File                           | Purpose                                                     |

+| `sql/initial_schema.sql`       | Base schema without seed data, used as standalone reference |
+| `sql/migrations/*.sql`         | Incremental migrations for production database updates      |
+
+**Maintenance Rules:**
+
+1. **Keep `master_schema_rollup.sql` and `initial_schema.sql` in sync** - These files should contain the same table definitions
+2. **When adding columns via migration**, also add them to both `master_schema_rollup.sql` and `initial_schema.sql`
+3. **Migrations are for production deployments** - They use `ALTER TABLE` to add columns incrementally
+4. **Schema files are for fresh installs** - They define the complete table structure
+5. **Test database uses `master_schema_rollup.sql`** - If schema files are out of sync with migrations, tests will fail
+
+**Example:** When `002_expiry_tracking.sql` adds `purchase_date` to `pantry_items`, that column must also exist in the `CREATE TABLE` statements in both `master_schema_rollup.sql` and `initial_schema.sql`.

+## Secrets and Environment Variables
+
+**CRITICAL**: This project uses **Gitea CI/CD secrets** for all sensitive configuration. There is NO `/etc/flyer-crawler/environment` file or similar local config file on the server.
+
+### Server Directory Structure
+
+| Path                                          | Environment | Notes                                            |
+| --------------------------------------------- | ----------- | ------------------------------------------------ |
+| `/var/www/flyer-crawler.projectium.com/`      | Production  | NO `.env` file - secrets injected via CI/CD only |
+| `/var/www/flyer-crawler-test.projectium.com/` | Test        | Has `.env.test` file for test-specific config    |
+
+### How Secrets Work
+
+1. **Gitea Secrets**: All secrets are stored in Gitea repository settings (Settings → Secrets)
+2. **CI/CD Injection**: Secrets are injected during deployment via `.gitea/workflows/deploy-to-prod.yml` and `deploy-to-test.yml`
+3. **PM2 Environment**: The CI/CD workflow passes secrets to PM2 via environment variables, which are then available to the application
+
+### Key Files for Configuration
+
+| File                                  | Purpose                                              |
+| ------------------------------------- | ---------------------------------------------------- |
+| `src/config/env.ts`                   | Centralized config with Zod schema validation        |
+| `ecosystem.config.cjs`                | PM2 process config - reads from `process.env`        |
+| `.gitea/workflows/deploy-to-prod.yml` | Production deployment with secret injection          |
+| `.gitea/workflows/deploy-to-test.yml` | Test deployment with secret injection                |
+| `.env.example`                        | Template showing all available environment variables |
+| `.env.test`                           | Test environment overrides (only on test server)     |
+
+### Adding New Secrets
+
+To add a new secret (e.g., `SENTRY_DSN`):
+
+1. Add the secret to Gitea repository settings
+2. Update the relevant workflow file (e.g., `deploy-to-prod.yml`) to inject it:
+
+   ```yaml
+   SENTRY_DSN: ${{ secrets.SENTRY_DSN }}
+   ```
+
+3. Update `ecosystem.config.cjs` to read it from `process.env`
+4. Update `src/config/env.ts` schema if validation is needed
+5. Update `.env.example` to document the new variable
+
+### Current Gitea Secrets
+
+**Shared (used by both environments):**
+
+- `DB_HOST` - Database host (shared PostgreSQL server)
+- `JWT_SECRET` - Authentication
+- `GOOGLE_MAPS_API_KEY` - Google Maps
+- `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET` - Google OAuth
+- `GH_CLIENT_ID`, `GH_CLIENT_SECRET` - GitHub OAuth
+
+**Production-specific:**
+
+- `DB_USER_PROD`, `DB_PASSWORD_PROD` - Production database credentials (`flyer_crawler_prod`)
+- `DB_DATABASE_PROD` - Production database name (`flyer-crawler`)
+- `REDIS_PASSWORD_PROD` - Redis password (uses database 0)
+- `VITE_GOOGLE_GENAI_API_KEY` - Gemini API key for production
+- `SENTRY_DSN`, `VITE_SENTRY_DSN` - Bugsink error tracking DSNs (production projects)
+
+**Test-specific:**
+
+- `DB_USER_TEST`, `DB_PASSWORD_TEST` - Test database credentials (`flyer_crawler_test`)
+- `DB_DATABASE_TEST` - Test database name (`flyer-crawler-test`)
+- `REDIS_PASSWORD_TEST` - Redis password (uses database 1 for isolation)
+- `VITE_GOOGLE_GENAI_API_KEY_TEST` - Gemini API key for test
+- `SENTRY_DSN_TEST`, `VITE_SENTRY_DSN_TEST` - Bugsink error tracking DSNs (test projects)
+
+### Test Environment
+
+The test environment (`flyer-crawler-test.projectium.com`) uses **both** Gitea CI/CD secrets and a local `.env.test` file:
+
+- **Gitea secrets**: Injected during deployment via `.gitea/workflows/deploy-to-test.yml`
+- **`.env.test` file**: Located at `/var/www/flyer-crawler-test.projectium.com/.env.test` for local overrides
+- **Redis database 1**: Isolates test job queues from production (which uses database 0)
+- **PM2 process names**: Suffixed with `-test` (e.g., `flyer-crawler-api-test`)
+
+### Database User Setup (Test Environment)
+
+**CRITICAL**: The test database requires specific PostgreSQL permissions to be configured manually. Schema ownership alone is NOT sufficient - explicit privileges must be granted.
+
+**Database Users:**
+
+| User                 | Database             | Purpose    |
+| -------------------- | -------------------- | ---------- |
+| `flyer_crawler_prod` | `flyer-crawler`      | Production |
+| `flyer_crawler_test` | `flyer-crawler-test` | Testing    |
+
+**Required Setup Commands** (run as `postgres` superuser):
+
+```bash
+# Connect as postgres superuser
+sudo -u postgres psql
+
+# Create the test database and user (if not exists)
+CREATE DATABASE "flyer-crawler-test";
+CREATE USER flyer_crawler_test WITH PASSWORD 'your-password-here';
+
+# Grant ownership and privileges
+ALTER DATABASE "flyer-crawler-test" OWNER TO flyer_crawler_test;
+\c "flyer-crawler-test"
+ALTER SCHEMA public OWNER TO flyer_crawler_test;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_test;
+
+# Create required extension (must be done by superuser)
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+```
+
+**Why These Steps Are Necessary:**
+
+1. **Schema ownership alone is insufficient** - PostgreSQL requires explicit `GRANT CREATE, USAGE` privileges even when the user owns the schema
+2. **uuid-ossp extension** - Required by the application for UUID generation; must be created by a superuser before the app can use it
+3. **Separate users for prod/test** - Prevents accidental cross-environment data access; each environment has its own credentials in Gitea secrets
+
+**Verification:**
+
+```bash
+# Check schema privileges (should show 'UC' for flyer_crawler_test)
+psql -d "flyer-crawler-test" -c "\dn+ public"
+
+# Expected output:
+#  Name  |       Owner        |            Access privileges
+# -------+--------------------+------------------------------------------
+# public | flyer_crawler_test | flyer_crawler_test=UC/flyer_crawler_test
+```
+
+### Dev Container Environment
+
+The dev container runs its own **local Bugsink instance** - it does NOT connect to the production Bugsink server:
+
+- **Local Bugsink**: Runs at `http://localhost:8000` inside the container
+- **Pre-configured DSNs**: Set in `compose.dev.yml`, pointing to local instance
+- **Admin credentials**: `admin@localhost` / `admin`
+- **Isolated**: Dev errors stay local, don't pollute production/test dashboards
+- **No Gitea secrets needed**: Everything is self-contained in the container

-**Note:** MCP servers are currently only available in **Claude CLI**. Due to a bug in Claude VS Code extension, MCP servers do not work there yet.
+**Note:** MCP servers work in both **Claude CLI** and **Claude Code VS Code extension** (as of January 2026).
+
+### Sentry/Bugsink MCP Server Setup (ADR-015)
+
+To enable Claude Code to query and analyze application errors from Bugsink:
+
+1. **Install the MCP server**:
+
+   ```bash
+   # Clone the sentry-selfhosted-mcp repository
+   git clone https://github.com/ddfourtwo/sentry-selfhosted-mcp.git
+   cd sentry-selfhosted-mcp
+   npm install
+   ```
+
+2. **Configure Claude Code** (add to `.claude/mcp.json`):
+
+   ```json
+   {
+     "sentry-selfhosted-mcp": {
+       "command": "node",
+       "args": ["/path/to/sentry-selfhosted-mcp/dist/index.js"],
+       "env": {
+         "SENTRY_URL": "http://localhost:8000",
+         "SENTRY_AUTH_TOKEN": "<get-from-bugsink-ui>",
+         "SENTRY_ORG_SLUG": "flyer-crawler"
+       }
+     }
+   }
+   ```
+
+3. **Get the auth token**:
+   - Navigate to Bugsink UI at `http://localhost:8000`
+   - Log in with admin credentials
+   - Go to Settings > API Keys
+   - Create a new API key with read access
+
+4. **Available capabilities**:
+   - List projects and issues
+   - View detailed error events
+   - Search by error message or stack trace
+   - Update issue status (resolve, ignore)
+   - Add comments to issues
+
+### SSH Server Access
+
+Claude Code can execute commands on the production server via SSH:
+
+```bash
+# Basic command execution
+ssh root@projectium.com "command here"
+
+# Examples:
+ssh root@projectium.com "systemctl status logstash"
+ssh root@projectium.com "pm2 list"
+ssh root@projectium.com "tail -50 /var/www/flyer-crawler.projectium.com/logs/app.log"
+```
+
+**Use cases:**
+
+- Managing Logstash, PM2, NGINX, Redis services
+- Viewing server logs
+- Deploying configuration changes
+- Checking service status
+
+**Important:** SSH access requires the host machine to have SSH keys configured for `root@projectium.com`.

+
+### Testing Error Tracking
+
+Verify Bugsink is receiving events:
+
+```bash
+npx tsx scripts/test-bugsink.ts
+```
+
+This sends test error and info events. Check the Bugsink UI for:
+
+- `BugsinkTestError` in the backend project
+- Info message "Test info message from test-bugsink.ts"
+
+### Sentry SDK v10+ HTTP DSN Limitation
+
+The Sentry SDK v10+ enforces HTTPS-only DSNs by default. Since Bugsink runs locally over HTTP, our implementation uses the Sentry Store API directly instead of the SDK's built-in transport. This is handled transparently by the `sentry.server.ts` and `sentry.client.ts` modules.

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

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

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

+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.
