+### Database User Setup (Test Environment)
+
+**CRITICAL**: The test database requires specific PostgreSQL permissions to be configured manually. Schema ownership alone is NOT sufficient - explicit privileges must be granted.
+
+**Database Users:**
+
+| User                 | Database             | Purpose    |
+| -------------------- | -------------------- | ---------- |
+| `flyer_crawler_prod` | `flyer-crawler-prod` | Production |
+| `flyer_crawler_test` | `flyer-crawler-test` | Testing    |
+
+**Required Setup Commands** (run as `postgres` superuser):
+
+```bash
+# Connect as postgres superuser
+sudo -u postgres psql
+
+# Create the test database and user (if not exists)
+CREATE DATABASE "flyer-crawler-test";
+CREATE USER flyer_crawler_test WITH PASSWORD 'your-password-here';
+
+# Grant ownership and privileges
+ALTER DATABASE "flyer-crawler-test" OWNER TO flyer_crawler_test;
+\c "flyer-crawler-test"
+ALTER SCHEMA public OWNER TO flyer_crawler_test;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_test;
+
+# Create required extension (must be done by superuser)
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+```
+
+**Why These Steps Are Necessary:**
+
+1. **Schema ownership alone is insufficient** - PostgreSQL requires explicit `GRANT CREATE, USAGE` privileges even when the user owns the schema
+2. **uuid-ossp extension** - Required by the application for UUID generation; must be created by a superuser before the app can use it
+3. **Separate users for prod/test** - Prevents accidental cross-environment data access; each environment has its own credentials in Gitea secrets
+
+**Verification:**
+
+```bash
+# Check schema privileges (should show 'UC' for flyer_crawler_test)
+psql -d "flyer-crawler-test" -c "\dn+ public"
+
+# Expected output:
+#  Name  |       Owner        |            Access privileges

+# 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

+
+## 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

+# 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     |
+
+---
+
+## Implementation Timeline
+
+| Phase     | Description                    | Effort       | Priority |
+| --------- | ------------------------------ | ------------ | -------- |
+| 1.1       | deals.integration.test.ts      | 30 min       | High     |
+| 1.2       | reactions.integration.test.ts  | 45 min       | High     |
+| 1.3       | edge-cases.integration.test.ts | 1.5 hours    | High     |
+| 1.4       | data-integrity.integration.ts  | 2 hours      | High     |
+| 2.1       | Extend budget tests            | 30 min       | Medium   |
+| 2.2       | Extend admin tests             | 1 hour       | Medium   |
+| 2.3       | Extend auth tests              | 45 min       | Medium   |
+| 2.4       | Extend recipe tests            | 30 min       | Medium   |
+| 2.5       | Extend notification tests      | 30 min       | Medium   |
+| 4.x       | Documentation updates          | 30 min       | Low      |
+| **Total** |                                | **~8 hours** |          |
+
+---
+
+## Verification Strategy
+
+For each new test file, verify by running:
+
+```bash
+# In dev container
+npm run test:integration -- --run src/tests/integration/<file>.test.ts
+```
+
+All tests should:
+
+1. Pass consistently (no flaky tests)
+2. Run in isolation (no shared state)
+3. Clean up test data (use `cleanupDb()`)
+4. Follow existing patterns in the codebase
+
+---
+
+## Risks and Mitigations
+
+| Risk                                 | Mitigation                                          |
+| ------------------------------------ | --------------------------------------------------- |
+| Test flakiness from async operations | Use proper waitFor/polling utilities                |
+| Database state leakage between tests | Strict cleanup in afterEach/afterAll                |
+| Queue state affecting test isolation | Drain/pause queues in tests that interact with them |
+| Port conflicts                       | Use dedicated test port (3099)                      |
+
+---
+
+## Approval Request
+
+Please review and approve this plan. Upon approval, implementation will proceed in priority order (Phase 1 first).
+
+**Questions for clarification**:
+
+1. Should the deals/reactions routes remain mounted, or was that a temporary fix?
+2. Is the recipe fork failure for seed recipes expected behavior or a bug to fix?
+3. Any preference on splitting Phase 1 into multiple PRs vs one large PR?
