 # Claude Code Project Instructions
 
+## Communication Style: Ask Before Assuming
+
+**IMPORTANT**: When helping with tasks, **ask clarifying questions before making assumptions**. Do not assume:
+
+- What steps the user has or hasn't completed
+- What the user already knows or has configured
+- What external services (OAuth providers, APIs, etc.) are already set up
+- What secrets or credentials have already been created
+
+Instead, ask the user to confirm the current state before providing instructions or making recommendations. This prevents wasted effort and respects the user's existing work.
+
 ## Platform Requirement: Linux Only
 
 **CRITICAL**: This application is designed to run **exclusively on Linux**. See [ADR-014](docs/adr/0014-containerization-and-deployment-strategy.md) for full details.
 
+### Environment Terminology
+
+- **Dev Container** (or just "dev"): The containerized Linux development environment (`flyer-crawler-dev`). This is where all development and testing should occur.
+- **Host**: The Windows machine running Podman/Docker and VS Code.
+
+When instructions say "run in dev" or "run in the dev container", they mean executing commands inside the `flyer-crawler-dev` container.
+
 ### Test Execution Rules
 
-1. **ALL tests MUST be executed on Linux** - either in the Dev Container or on a Linux host
-2. **NEVER run tests directly on Windows** - test results from Windows are unreliable
-3. **Always use the Dev Container for testing** when developing on Windows
+1. **ALL tests MUST be executed in the dev container** - the Linux container environment
+2. **NEVER run tests directly on Windows host** - test results from Windows are unreliable
+3. **Always use the dev container for testing** when developing on Windows
 
 ### How to Run Tests Correctly
 
 ```bash
 # If on Windows, first open VS Code and "Reopen in Container"
-# Then run tests inside the container:
+# Then run tests inside the dev container:
 npm test           # Run all unit tests
 npm run test:unit  # Run unit tests only
 npm run test:integration  # Run integration tests (requires DB/Redis)
 ```
 
+### Running Tests via Podman (from Windows host)
+
+The command to run unit tests in the dev container via podman:
+
+```bash
+podman exec -it flyer-crawler-dev npm run test:unit
+```
+
+The command to run integration tests in the dev container via podman:
+
+```bash
+podman exec -it flyer-crawler-dev npm run test:integration
+```
+
+For running specific test files:
+
+```bash
+podman exec -it flyer-crawler-dev npm test -- --run src/hooks/useAuth.test.tsx
+```
+
 ### Why Linux Only?
 
 - Path separators: Code uses POSIX-style paths (`/`) which may break on Windows

+
+## Code Change Verification
+
+After making any code changes, **always run a type-check** to catch TypeScript errors before committing:
+
+```bash
+npm run type-check
+```
+
+This prevents linting/type errors from being introduced into the codebase.

+## Known Integration Test Issues and Solutions
+
+This section documents common test issues encountered in integration tests, their root causes, and solutions. These patterns recur frequently.
+
+### 1. Vitest globalSetup Runs in Separate Node.js Context
+
+**Problem:** Vitest's `globalSetup` runs in a completely separate Node.js context from test files. This means:
+
+- Singletons created in globalSetup are NOT the same instances as those in test files
+- `global`, `globalThis`, and `process` are all isolated between contexts
+- `vi.spyOn()` on module exports doesn't work cross-context
+- Dependency injection via setter methods fails across contexts
+
+**Affected Tests:** Any test trying to inject mocks into BullMQ worker services (e.g., AI failure tests, DB failure tests)
+
+**Solution Options:**
+
+1. Mark tests as `.todo()` until an API-based mock injection mechanism is implemented
+2. Create test-only API endpoints that allow setting mock behaviors via HTTP
+3. Use file-based or Redis-based mock flags that services check at runtime
+
+**Example of affected code pattern:**
+
+```typescript
+// This DOES NOT work - different module instances
+const { flyerProcessingService } = await import('../../services/workers.server');
+flyerProcessingService._getAiProcessor()._setExtractAndValidateData(mockFn);
+// The worker uses a different flyerProcessingService instance!
+```
+
+### 2. BullMQ Cleanup Queue Deleting Files Before Test Verification
+
+**Problem:** The cleanup worker runs in the globalSetup context and processes cleanup jobs even when tests spy on `cleanupQueue.add()`. The spy intercepts calls in the test context, but jobs already queued run in the worker's context.
+
+**Affected Tests:** EXIF/PNG metadata stripping tests that need to verify file contents before deletion
+
+**Solution:** Drain and pause the cleanup queue before the test:
+
+```typescript
+const { cleanupQueue } = await import('../../services/queues.server');
+await cleanupQueue.drain(); // Remove existing jobs
+await cleanupQueue.pause(); // Prevent new jobs from processing
+// ... run test ...
+await cleanupQueue.resume(); // Restore normal operation
+```
+
+### 3. Cache Invalidation After Direct Database Inserts
+
+**Problem:** Tests that insert data directly via SQL (bypassing the service layer) don't trigger cache invalidation. Subsequent API calls return stale cached data.
+
+**Affected Tests:** Any test using `pool.query()` to insert flyers, stores, or other cached entities
+
+**Solution:** Manually invalidate the cache after direct inserts:
+
+```typescript
+await pool.query('INSERT INTO flyers ...');
+await cacheService.invalidateFlyers(); // Clear stale cache
+```
+
+### 4. Unique Filenames Required for Test Isolation
+
+**Problem:** Multer generates predictable filenames in test environments, causing race conditions when multiple tests upload files concurrently or in sequence.
+
+**Affected Tests:** Flyer processing tests, file upload tests
+
+**Solution:** Always use unique filenames with timestamps:
+
+```typescript
+// In multer.middleware.ts
+const uniqueSuffix = `${Date.now()}-${Math.round(Math.random() * 1e9)}`;
+cb(null, `${file.fieldname}-${uniqueSuffix}-${sanitizedOriginalName}`);
+```
+
+### 5. Response Format Mismatches
+
+**Problem:** API response formats may change, causing tests to fail when expecting old formats.
+
+**Common Issues:**
+
+- `response.body.data.jobId` vs `response.body.data.job.id`
+- Nested objects vs flat response structures
+- Type coercion (string vs number for IDs)
+
+**Solution:** Always log response bodies during debugging and update test assertions to match actual API contracts.
+
+### 6. External Service Availability
+
+**Problem:** Tests depending on external services (PM2, Redis health checks) fail when those services aren't available in the test environment.
+
+**Solution:** Use try/catch with graceful degradation or mock the external service checks.
+

+| filesystem          | File system access                       |
+| fetch               | Web fetching                             |
+| markitdown          | Convert documents to markdown            |
+| sequential-thinking | Step-by-step reasoning                   |
+| memory              | Knowledge graph persistence              |
+| postgres            | Direct database queries (localhost:5432) |
+| playwright          | Browser automation and testing           |
+| redis               | Redis cache inspection (localhost:6379)  |
+
+**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.

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

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

 ## Context
 
 As the API grows, it becomes increasingly difficult for frontend developers and other consumers to understand its endpoints, request formats, and response structures. There is no single source of truth for API documentation.
 
+Key requirements:
+
+1. **Developer Experience**: Developers need interactive documentation to explore and test API endpoints.
+2. **Code-Documentation Sync**: Documentation should stay in sync with the actual code to prevent drift.
+3. **Low Maintenance Overhead**: The documentation approach should be "fast and lite" - minimal additional work for developers.
+4. **Security**: Documentation should not expose sensitive information in production environments.
+
 ## Decision
 
-We will adopt **OpenAPI (Swagger)** for API documentation. We will use tools (e.g., JSDoc annotations with `swagger-jsdoc`) to generate an `openapi.json` specification directly from the route handler source code. This specification will be served via a UI like Swagger UI for interactive exploration.
+We will adopt **OpenAPI 3.0 (Swagger)** for API documentation using the following approach:
+
+1. **JSDoc Annotations**: Use `swagger-jsdoc` to generate OpenAPI specs from JSDoc comments in route files.
+2. **Swagger UI**: Use `swagger-ui-express` to serve interactive documentation at `/docs/api-docs`.
+3. **Environment Restriction**: Only expose the Swagger UI in development and test environments, not production.
+4. **Incremental Adoption**: Start with key public routes and progressively add annotations to all endpoints.
+
+### Tooling Selection
+
+| Tool                 | Purpose                                        |
+| -------------------- | ---------------------------------------------- |
+| `swagger-jsdoc`      | Generates OpenAPI 3.0 spec from JSDoc comments |
+| `swagger-ui-express` | Serves interactive Swagger UI                  |
+
+**Why JSDoc over separate schema files?**
+
+- Documentation lives with the code, reducing drift
+- No separate files to maintain
+- Developers see documentation when editing routes
+- Lower learning curve for the team
+
+## Implementation Details
+
+### OpenAPI Configuration
+
+Located in `src/config/swagger.ts`:
+
+```typescript
+import swaggerJsdoc from 'swagger-jsdoc';
+
+const options: swaggerJsdoc.Options = {
+  definition: {
+    openapi: '3.0.0',
+    info: {
+      title: 'Flyer Crawler API',
+      version: '1.0.0',
+      description: 'API for the Flyer Crawler application',
+      contact: {
+        name: 'API Support',
+      },
+    },
+    servers: [
+      {
+        url: '/api',
+        description: 'API server',
+      },
+    ],
+    components: {
+      securitySchemes: {
+        bearerAuth: {
+          type: 'http',
+          scheme: 'bearer',
+          bearerFormat: 'JWT',
+        },
+      },
+    },
+  },
+  apis: ['./src/routes/*.ts'],
+};
+
+export const swaggerSpec = swaggerJsdoc(options);
+```
+
+### JSDoc Annotation Pattern
+
+Each route handler should include OpenAPI annotations using the `@openapi` tag:
+
+```typescript
+/**
+ * @openapi
+ * /health/ping:
+ *   get:
+ *     summary: Simple ping endpoint
+ *     description: Returns a pong response to verify server is responsive
+ *     tags:
+ *       - Health
+ *     responses:
+ *       200:
+ *         description: Server is responsive
+ *         content:
+ *           application/json:
+ *             schema:

+ */
+router.get('/ping', validateRequest(emptySchema), (_req: Request, res: Response) => {
+  return sendSuccess(res, { message: 'pong' });
+});
+```
+
+### Route Documentation Priority
+
+Document routes in this order of priority:
+
+1. **Health Routes** - `/api/health/*` (public, critical for operations)
+2. **Auth Routes** - `/api/auth/*` (public, essential for integration)
+3. **Gamification Routes** - `/api/achievements/*` (simple, good example)
+4. **Flyer Routes** - `/api/flyers/*` (core functionality)
+5. **User Routes** - `/api/users/*` (common CRUD patterns)
+6. **Remaining Routes** - Budget, Recipe, Admin, etc.
+
+### Swagger UI Setup
+
+In `server.ts`, add the Swagger UI middleware (development/test only):
+
+```typescript
+import swaggerUi from 'swagger-ui-express';
+import { swaggerSpec } from './src/config/swagger';
+
+// Only serve Swagger UI in non-production environments
+if (process.env.NODE_ENV !== 'production') {
+  app.use('/docs/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerSpec));
+
+  // Optionally expose raw JSON spec for tooling
+  app.get('/docs/api-docs.json', (_req, res) => {
+    res.setHeader('Content-Type', 'application/json');
+    res.send(swaggerSpec);
+  });
+}
+```
+
+### Response Schema Standardization
+
+All API responses follow the standardized format from [ADR-028](./0028-api-response-standardization.md):
+
+```typescript
+// Success response
+{
+  "success": true,
+  "data": { ... }
+}
+
+// Error response
+{
+  "success": false,
+  "error": {
+    "code": "ERROR_CODE",
+    "message": "Human-readable message"
+  }
+}
+```
+
+Define reusable schema components for these patterns:
+
+```typescript
+/**
+ * @openapi
+ * components:
+ *   schemas:
+ *     SuccessResponse:
+ *       type: object
+ *       properties:
+ *         success:
+ *           type: boolean
+ *           example: true
+ *         data:
+ *           type: object
+ *     ErrorResponse:
+ *       type: object
+ *       properties:
+ *         success:
+ *           type: boolean
+ *           example: false
+ *         error:
+ *           type: object
+ *           properties:
+ *             code:
+ *               type: string
+ *             message:
+ *               type: string
+ */
+```
+
+### Security Considerations
+
+1. **Production Disabled**: Swagger UI is not available in production to prevent information disclosure.
+2. **No Sensitive Data**: Never include actual secrets, tokens, or PII in example values.
+3. **Authentication Documented**: Clearly document which endpoints require authentication.
+
+## API Route Tags
+
+Organize endpoints using consistent tags:
+
+| Tag          | Description                        | Routes                |
+| ------------ | ---------------------------------- | --------------------- |
+| Health       | Server health and readiness checks | `/api/health/*`       |
+| Auth         | Authentication and authorization   | `/api/auth/*`         |
+| Users        | User profile management            | `/api/users/*`        |
+| Flyers       | Flyer uploads and retrieval        | `/api/flyers/*`       |
+| Achievements | Gamification and leaderboards      | `/api/achievements/*` |
+| Budgets      | Budget tracking                    | `/api/budgets/*`      |
+| Recipes      | Recipe management                  | `/api/recipes/*`      |
+| Admin        | Administrative operations          | `/api/admin/*`        |
+| System       | System status and monitoring       | `/api/system/*`       |
+
+## Testing
+
+Verify API documentation is correct by:
+
+1. **Manual Review**: Navigate to `/docs/api-docs` and test each endpoint.
+2. **Spec Validation**: Use OpenAPI validators to check the generated spec.
+3. **Integration Tests**: Existing integration tests serve as implicit documentation verification.
 
 ## Consequences
 
-- **Positive**: Creates a single source of truth for API documentation that stays in sync with the code. Enables auto-generation of client SDKs and simplifies testing.
-- **Negative**: Requires developers to maintain JSDoc annotations on all routes. Adds a build step and new dependencies to the project.
+### Positive
+
+- **Single Source of Truth**: Documentation lives with the code and stays in sync.
+- **Interactive Exploration**: Developers can try endpoints directly from the UI.
+- **SDK Generation**: OpenAPI spec enables automatic client SDK generation.
+- **Onboarding**: New developers can quickly understand the API surface.
+- **Low Overhead**: JSDoc annotations are minimal additions to existing code.
+
+### Negative
+
+- **Maintenance Required**: Developers must update annotations when routes change.
+- **Build Dependency**: Adds `swagger-jsdoc` and `swagger-ui-express` packages.
+- **Initial Investment**: Existing routes need annotations added incrementally.
+
+### Mitigation
+
+- Include documentation checks in code review process.
+- Start with high-priority routes and expand coverage over time.
+- Use TypeScript types to reduce documentation duplication where possible.

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

+| Recipe Sharer        | Share a recipe with another user for the first time.        | share-2      | 15     |
+| List Sharer          | Share a shopping list with another user for the first time. | list         | 20     |

+| First-Upload         | Upload your first flyer.                                    | upload-cloud | 25     |
+
+### Achievement Triggers
+
+#### User Registration (Database Trigger)
+
+Awards "Welcome Aboard" when a new user is created:
+
+```sql
+-- In handle_new_user() function
+PERFORM public.award_achievement(new.user_id, 'Welcome Aboard');
+```
+
+#### Flyer Upload (Database Trigger + Application Code)
+
+Awards "First-Upload" when a flyer is inserted with an `uploaded_by` value:
+
+```sql
+-- In log_new_flyer() trigger function
+IF NEW.uploaded_by IS NOT NULL THEN
+    PERFORM public.award_achievement(NEW.uploaded_by, 'First-Upload');
+END IF;
+```
+
+Additionally, the `FlyerPersistenceService.saveFlyer()` method explicitly awards the achievement within the transaction:
+
+```typescript
+// In src/services/flyerPersistenceService.server.ts
+if (userId) {
+  const gamificationRepo = new GamificationRepository(client);
+  await gamificationRepo.awardAchievement(userId, 'First-Upload', logger);
+}
+```
+
+### Repository Layer
+
+Located in `src/services/db/gamification.db.ts`:
+
+```typescript
+export class GamificationRepository {
+  private db: Pick<Pool | PoolClient, 'query'>;
+
+  constructor(db: Pick<Pool | PoolClient, 'query'> = getPool()) {
+    this.db = db;
+  }
+
+  async getUserAchievements(
+    userId: string,
+    logger: Logger,
+  ): Promise<(UserAchievement & Achievement)[]> {
+    const query = `
+      SELECT ua.user_id, ua.achievement_id, ua.achieved_at,
+             a.name, a.description, a.icon, a.points_value, a.created_at
+      FROM public.user_achievements ua
+      JOIN public.achievements a ON ua.achievement_id = a.achievement_id
+      WHERE ua.user_id = $1
+      ORDER BY ua.achieved_at DESC;
+    `;
+    const res = await this.db.query(query, [userId]);
+    return res.rows;
+  }
+
+  async awardAchievement(userId: string, achievementName: string, logger: Logger): Promise<void> {
+    await this.db.query('SELECT public.award_achievement($1, $2)', [userId, achievementName]);
+  }
+
+  async getLeaderboard(limit: number, logger: Logger): Promise<LeaderboardUser[]> {
+    const query = `
+      SELECT user_id, full_name, avatar_url, points,
+             RANK() OVER (ORDER BY points DESC) as rank
+      FROM public.profiles
+      ORDER BY points DESC, full_name ASC
+      LIMIT $1;
+    `;
+    const res = await this.db.query(query, [limit]);
+    return res.rows;
+  }
+}
+```
+
+### API Endpoints
+
+| Method | Endpoint                        | Description                     |
+| ------ | ------------------------------- | ------------------------------- |
+| GET    | `/api/achievements`             | List all available achievements |
+| GET    | `/api/achievements/me`          | Get current user's achievements |
+| GET    | `/api/achievements/leaderboard` | Get top users by points         |
+
+## Testing Considerations
+
+### Critical Testing Requirements
+
+When testing gamification features, be aware of the following:
+
+1. **Database Seed Data**: Achievement definitions must exist in the database before tests run. The `award_achievement()` function silently returns if the achievement name doesn't exist.
+
+2. **Transactional Context**: When awarding achievements from within a transaction:
+   - The achievement is visible within the transaction immediately
+   - External queries won't see the achievement until the transaction commits
+   - Tests should wait for job completion before asserting achievement state
+
+3. **Vitest Global Setup Context**: The integration test global setup runs in a separate Node.js context. Achievement verification must use direct database queries, not mocked services.
+
+4. **Achievement Idempotency**: Calling `award_achievement()` multiple times for the same user/achievement combination is safe and expected. Only the first call actually inserts.
+
+### Example Integration Test Pattern
+
+```typescript
+it('should award the "First Upload" achievement after flyer processing', async () => {
+  // 1. Create user (awards "Welcome Aboard" via database trigger)
+  const { user: testUser, token } = await createAndLoginUser({...});
+
+  // 2. Upload flyer (triggers async job)
+  const uploadResponse = await request
+    .post('/api/flyers/upload')
+    .set('Authorization', `Bearer ${token}`)
+    .attach('flyerFile', testImagePath);
+  expect(uploadResponse.status).toBe(202);
+
+  // 3. Wait for job to complete
+  await poll(async () => {
+    const status = await request.get(`/api/flyers/job/${jobId}/status`);
+    return status.body.data.status === 'completed';
+  }, { timeout: 15000 });
+
+  // 4. Wait for achievements to be visible (transaction committed)
+  await vi.waitUntil(async () => {
+    const achievements = await db.gamificationRepo.getUserAchievements(
+      testUser.user.user_id,
+      logger
+    );
+    return achievements.length >= 2; // Welcome Aboard + First-Upload
+  }, { timeout: 15000, interval: 500 });
+
+  // 5. Assert specific achievements
+  const userAchievements = await db.gamificationRepo.getUserAchievements(
+    testUser.user.user_id,
+    logger
+  );
+  expect(userAchievements.find(a => a.name === 'Welcome Aboard')).toBeDefined();
+  expect(userAchievements.find(a => a.name === 'First-Upload')).toBeDefined();
+});
+```
+
+### Common Test Pitfalls
+
+1. **Missing Seed Data**: If tests fail with "achievement not found", ensure the test database has the achievements table populated.
+
+2. **Race Conditions**: Achievement awards in async jobs may not be visible immediately. Always poll or use `vi.waitUntil()`.
+
+3. **Wrong User ID**: Verify the user ID passed to `awardAchievement()` matches the user created in the test.
+
+4. **Transaction Isolation**: When querying within a test, use the same database connection if checking mid-transaction state.
+
+## Consequences
+
+### Positive
+
+- **Engagement**: Users have clear goals and rewards for platform activity.
+- **Scalability**: Points stored on profile enable O(1) leaderboard sorting.
+- **Reliability**: Database-level idempotency prevents duplicate awards.
+- **Flexibility**: New achievements can be added via SQL without code changes.
+
+### Negative
+
+- **Complexity**: Multiple award paths (triggers + application code) require careful coordination.
+- **Testing**: Async nature of some awards complicates integration testing.
+- **Coupling**: Achievement names are strings; typos fail silently.
+
+### Mitigation
+
+- Use constants for achievement names in application code.
+- Document all award trigger points clearly.
+- Test each achievement path independently.
+

+# ADR-050: PostgreSQL Function Observability
+
+**Date**: 2026-01-11
+
+**Status**: Proposed
+
+**Related**: [ADR-015](0015-application-performance-monitoring-and-error-tracking.md), [ADR-004](0004-standardized-application-wide-structured-logging.md)
+
+## Context
+
+The application uses 30+ PostgreSQL functions and 11+ triggers for business logic, including:
+
+- Recipe recommendations and search
+- Shopping list generation from menu plans
+- Price history tracking
+- Achievement awards
+- Activity logging
+- User profile creation
+
+**Current Problem**: These database functions can fail silently in several ways:
+
+1. **`ON CONFLICT DO NOTHING`** - Swallows constraint violations without notification
+2. **`IF NOT FOUND THEN RETURN;`** - Silently exits when data is missing
+3. **Trigger functions returning `NULL`** - No indication of partial failures
+4. **No logging inside functions** - No visibility into function execution
+
+When these silent failures occur:
+
+- The application layer receives no error (function "succeeds" but does nothing)
+- No logs are generated for debugging
+- Issues are only discovered when users report missing data
+- Root cause analysis is extremely difficult
+
+**Example of Silent Failure**:
+
+```sql
+-- This function silently does nothing if achievement doesn't exist
+CREATE OR REPLACE FUNCTION public.award_achievement(p_user_id UUID, p_achievement_name TEXT)
+RETURNS void AS $$
+BEGIN
+    SELECT achievement_id INTO v_achievement_id FROM achievements WHERE name = p_achievement_name;
+    IF v_achievement_id IS NULL THEN
+        RETURN;  -- Silent failure - no log, no error
+    END IF;
+    -- ...
+END;
+$$;
+```
+
+ADR-015 established Logstash + Bugsink for error tracking, with PostgreSQL log integration marked as "future". This ADR defines the implementation.
+
+## Decision
+
+We will implement a standardized PostgreSQL function observability strategy with three tiers of logging severity:
+
+### 1. Function Logging Helper
+
+Create a reusable logging function that outputs structured JSON to PostgreSQL logs:
+
+```sql
+-- Function to emit structured log messages from PL/pgSQL

+
+### 2. Logging Tiers
+
+#### Tier 1: Critical Functions (Always Log)
+
+Functions where silent failure causes data corruption or user-facing issues:
+
+| Function                           | Log Events                              |
+| ---------------------------------- | --------------------------------------- |
+| `handle_new_user()`                | User creation, profile creation, errors |
+| `award_achievement()`              | Achievement not found, already awarded  |
+| `approve_correction()`             | Correction not found, permission denied |
+| `complete_shopping_list()`         | List not found, permission denied       |
+| `add_menu_plan_to_shopping_list()` | Permission denied, items added          |
+| `fork_recipe()`                    | Original not found, fork created        |
+
+**Pattern**:
+
+```sql
+CREATE OR REPLACE FUNCTION public.award_achievement(p_user_id UUID, p_achievement_name TEXT)
+RETURNS void AS $$
+DECLARE
+    v_achievement_id BIGINT;
+    v_points_value INTEGER;
+    v_context JSONB;
+BEGIN
+    v_context := jsonb_build_object('user_id', p_user_id, 'achievement_name', p_achievement_name);
+
+    SELECT achievement_id, points_value INTO v_achievement_id, v_points_value
+    FROM public.achievements WHERE name = p_achievement_name;
+
+    IF v_achievement_id IS NULL THEN
+        -- Log the issue instead of silent return
+        PERFORM fn_log('WARNING', 'award_achievement',
+            'Achievement not found: ' || p_achievement_name, v_context);
+        RETURN;
+    END IF;
+
+    INSERT INTO public.user_achievements (user_id, achievement_id)
+    VALUES (p_user_id, v_achievement_id)
+    ON CONFLICT (user_id, achievement_id) DO NOTHING;
+
+    IF FOUND THEN
+        UPDATE public.profiles SET points = points + v_points_value WHERE user_id = p_user_id;
+        PERFORM fn_log('INFO', 'award_achievement',
+            'Achievement awarded: ' || p_achievement_name, v_context);
+    END IF;
+END;
+$$;
+```
+
+#### Tier 2: Business Logic Functions (Log on Anomalies)
+
+Functions where unexpected conditions should be logged but aren't critical:
+
+| Function                               | Log Events                         |
+| -------------------------------------- | ---------------------------------- |
+| `suggest_master_item_for_flyer_item()` | No match found (below threshold)   |
+| `recommend_recipes_for_user()`         | No recommendations generated       |
+| `find_recipes_from_pantry()`           | Empty pantry, no recipes found     |
+| `get_best_sale_prices_for_user()`      | No watched items, no current sales |
+
+**Pattern**: Log when results are unexpectedly empty or inputs are invalid.
+
+#### Tier 3: Triggers (Log Errors Only)
+
+Triggers should be fast, so only log when something goes wrong:
+
+| Trigger Function                              | Log Events                |
+| --------------------------------------------- | ------------------------- |
+| `update_price_history_on_flyer_item_insert()` | Failed to update history  |
+| `update_recipe_rating_aggregates()`           | Rating calculation failed |
+| `log_new_recipe()`                            | Profile lookup failed     |
+| `log_new_flyer()`                             | Store lookup failed       |
+
+### 3. PostgreSQL Configuration
+
+Enable logging in `postgresql.conf`:
+
+```ini
+# Log all function notices and above
+log_min_messages = notice
+
+# Include function name in log prefix
+log_line_prefix = '%t [%p] %u@%d '
+
+# Log to file for Logstash pickup
+logging_collector = on
+log_directory = '/var/log/postgresql'
+log_filename = 'postgresql-%Y-%m-%d.log'
+log_rotation_age = 1d
+log_rotation_size = 100MB
+
+# Capture slow queries from functions
+log_min_duration_statement = 1000  # Log queries over 1 second
+```
+
+### 4. Logstash Integration
+
+Update the Logstash pipeline (extends ADR-015 configuration):
+
+```conf
+# PostgreSQL function log input
+input {
+  file {
+    path => "/var/log/postgresql/*.log"
+    type => "postgres"
+    tags => ["postgres"]
+    start_position => "beginning"
+    sincedb_path => "/var/lib/logstash/sincedb_postgres"
+  }
+}
+
+filter {
+  if [type] == "postgres" {
+    # Extract timestamp and process ID from PostgreSQL log prefix
+    grok {
+      match => { "message" => "%{TIMESTAMP_ISO8601:pg_timestamp} \[%{POSINT:pg_pid}\] %{USER:pg_user}@%{WORD:pg_database} %{GREEDYDATA:pg_message}" }
+    }
+
+    # Check if this is a structured JSON log from fn_log()
+    if [pg_message] =~ /^\{.*"source":"postgresql".*\}$/ {
+      json {
+        source => "pg_message"
+        target => "fn_log"
+      }
+
+      # Mark as error if level is WARNING or ERROR
+      if [fn_log][level] in ["WARNING", "ERROR"] {
+        mutate { add_tag => ["error", "db_function"] }
+      }
+    }
+
+    # Also catch native PostgreSQL errors
+    if [pg_message] =~ /^ERROR:/ or [pg_message] =~ /^FATAL:/ {
+      mutate { add_tag => ["error", "postgres_native"] }
+    }
+  }
+}
+
+output {
+  if "error" in [tags] and "postgres" in [tags] {
+    http {
+      url => "http://localhost:8000/api/store/"
+      http_method => "post"
+      format => "json"
+    }
+  }
+}
+```
+
+### 5. Dual-File Update Requirement
+
+**IMPORTANT**: All SQL function changes must be applied to BOTH files:
+
+1. `sql/Initial_triggers_and_functions.sql` - Used for incremental updates
+2. `sql/master_schema_rollup.sql` - Used for fresh database setup
+
+Both files must remain in sync for triggers and functions.
+
+## Implementation Steps
+
+1. **Create `fn_log()` helper function**:
+   - Add to both `Initial_triggers_and_functions.sql` and `master_schema_rollup.sql`
+   - Test with `SELECT fn_log('INFO', 'test', 'Test message', '{"key": "value"}'::jsonb);`
+
+2. **Update Tier 1 critical functions** (highest priority):
+   - `award_achievement()` - Log missing achievements, duplicate awards
+   - `handle_new_user()` - Log user creation success/failure
+   - `approve_correction()` - Log not found, permission denied
+   - `complete_shopping_list()` - Log permission checks
+   - `add_menu_plan_to_shopping_list()` - Log permission checks, items added
+   - `fork_recipe()` - Log original not found
+
+3. **Update Tier 2 business logic functions**:
+   - Add anomaly logging to suggestion/recommendation functions
+   - Log empty result sets with context
+
+4. **Update Tier 3 trigger functions**:
+   - Add error-only logging to critical triggers
+   - Wrap complex trigger logic in exception handlers
+
+5. **Configure PostgreSQL logging**:
+   - Update `postgresql.conf` in dev container
+   - Update production PostgreSQL configuration
+   - Verify logs appear in expected location
+
+6. **Update Logstash pipeline**:
+   - Add PostgreSQL input to `bugsink.conf`
+   - Add filter rules for structured JSON extraction
+   - Test end-to-end: function log → Logstash → Bugsink
+
+7. **Verify in Bugsink**:
+   - Confirm database function errors appear as issues
+   - Verify context (user_id, function name, params) is captured
+
+## Consequences
+
+### Positive
+
+- **Visibility**: Silent failures become visible in error tracking
+- **Debugging**: Function execution context captured for root cause analysis
+- **Proactive detection**: Anomalies logged before users report issues
+- **Unified monitoring**: Database errors appear alongside application errors in Bugsink
+- **Structured logs**: JSON format enables filtering and aggregation
+
+### Negative
+
+- **Performance overhead**: Logging adds latency to function execution
+- **Log volume**: Tier 1/2 functions may generate significant log volume
+- **Maintenance**: Two SQL files must be kept in sync
+- **PostgreSQL configuration**: Requires access to `postgresql.conf`
+
+### Mitigations
+
+- **Performance**: Only log meaningful events, not every function call
+- **Log volume**: Use appropriate log levels; Logstash filters reduce noise
+- **Sync**: Add CI check to verify SQL files match for function definitions
+- **Configuration**: Document PostgreSQL settings in deployment runbook
+
+## Examples
+
+### Before (Silent Failure)
+
+```sql
+-- User thinks achievement was awarded, but it silently failed
+SELECT award_achievement('user-uuid', 'Nonexistent Badge');
+-- Returns: void (no error, no log)
+-- Result: User never gets achievement, nobody knows why
+```
+
+### After (Observable Failure)
+
+```sql
+SELECT award_achievement('user-uuid', 'Nonexistent Badge');
+-- Returns: void
+-- PostgreSQL log: {"timestamp":"2026-01-11T10:30:00Z","level":"WARNING","source":"postgresql","function":"award_achievement","message":"Achievement not found: Nonexistent Badge","context":{"user_id":"user-uuid","achievement_name":"Nonexistent Badge"}}
+-- Bugsink: New issue created with full context
+```
