+## Git Bash / MSYS Path Conversion Issue (Windows Host)
+
+**CRITICAL ISSUE**: Git Bash on Windows automatically converts Unix-style paths to Windows paths, which breaks Podman/Docker commands.
+
+### Problem Examples:
+
+```bash
+# This FAILS in Git Bash:
+podman exec container /usr/local/bin/script.sh
+# Git Bash converts to: C:/Program Files/Git/usr/local/bin/script.sh
+
+# This FAILS in Git Bash:
+podman exec container bash -c "cat /tmp/file.sql"
+# Git Bash converts /tmp to C:/Users/user/AppData/Local/Temp
+```
+
+### Solutions:
+
+1. **Use `sh -c` instead of `bash -c`** for single-quoted commands:
+
+   ```bash
+   podman exec container sh -c '/usr/local/bin/script.sh'
+   ```
+
+2. **Use double slashes** to escape path conversion:
+
+   ```bash
+   podman exec container //usr//local//bin//script.sh
+   ```
+
+3. **Set MSYS_NO_PATHCONV** environment variable:
+
+   ```bash
+   MSYS_NO_PATHCONV=1 podman exec container /usr/local/bin/script.sh
+   ```
+
+4. **Use Windows paths with forward slashes** when referencing host files:
+   ```bash
+   podman cp "d:/path/to/file" container:/tmp/file
+   ```
+
+**ALWAYS use one of these workarounds when running Bash commands on Windows that involve Unix paths inside containers.**

 ## Communication Style: Ask Before Assuming

 **IMPORTANT**: When helping with tasks, **ask clarifying questions before making assumptions**. Do not assume:

+- ✅ Added to [src/types.ts](src/types.ts):
+  - `StoreLocationWithAddress` - Store location with full address data
+  - `StoreWithLocations` - Store with all its locations
+  - `CreateStoreRequest` - API request type for creating stores
+
+### Phase 3: API Routes (100%)

+
+### Phase 6: Integration Test Updates (100% - ALL COMPLETE)
+
+- ✅ **admin.integration.test.ts** - Updated to use `createStoreWithLocation()`

+
+## Key Achievement
+
+**ALL PHASES COMPLETE**. The normalized structure (stores → store_locations → addresses) is now fully integrated:
+
+- ✅ Database layer with full test coverage (59 tests)
+- ✅ TypeScript types and interfaces
+- ✅ REST API with 7 endpoints (17 route tests)
+- ✅ All E2E tests (3) using normalized structure
+- ✅ All integration tests (5) using normalized structure
+- ✅ Test helpers for easy store+address creation
+- ✅ All database queries returning store data now include addresses (5 queries updated)
+- ✅ Full admin UI for store management (CRUD operations)
+- ✅ Store display components for frontend use
+- ✅ Mock factories for all store-related types (3 new functions)
+- ✅ Cache invalidation for all store operations (5 endpoints)
+
+**What's Working:**
+
+- Stores can be created with or without addresses
+- Multiple locations per store are supported
+- Full CRUD operations via API with automatic cache invalidation
+- Admin can manage stores through web UI at `/admin/stores`
+- Type-safe throughout the stack
+- All flyers, deals, and admin queries include full store address information
+- StoreCard component available for displaying stores in flyer/deal listings

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

+
+## Implementation Plan (NO CODE YET - APPROVAL REQUIRED)
+
+### Phase 1: Database Layer (Foundation)
+
+#### 1.1 Create StoreRepository ([src/services/db/store.db.ts](src/services/db/store.db.ts))
+
+Functions needed:
+
+- `getStoreById(storeId)` - Returns Store (basic)
+- `getStoreWithLocations(storeId)` - Returns Store + Address[]
+- `getAllStores()` - Returns Store[] (basic)
+- `getAllStoresWithLocations()` - Returns Array<Store & {locations: Address[]}>
+- `createStore(name, logoUrl?, createdBy?)` - Returns storeId
+- `updateStore(storeId, updates)` - Updates name/logo
+- `deleteStore(storeId)` - Cascades to store_locations
+- `searchStoresByName(query)` - For autocomplete
+
+**Test file**: [src/services/db/store.db.test.ts](src/services/db/store.db.test.ts)
+
+#### 1.2 Create StoreLocationRepository ([src/services/db/storeLocation.db.ts](src/services/db/storeLocation.db.ts))
+
+Functions needed:
+
+- `createStoreLocation(storeId, addressId)` - Links store to address
+- `getLocationsByStoreId(storeId)` - Returns StoreLocation[] with Address data
+- `deleteStoreLocation(storeLocationId)` - Unlinks
+- `updateStoreLocation(storeLocationId, newAddressId)` - Changes address
+
+**Test file**: [src/services/db/storeLocation.db.test.ts](src/services/db/storeLocation.db.test.ts)
+
+#### 1.3 Enhance AddressRepository ([src/services/db/address.db.ts](src/services/db/address.db.ts))
+
+Add functions:
+
+- `searchAddressesByText(query)` - For autocomplete
+- `getAddressesByStoreId(storeId)` - Convenience method
+
+**Files to modify**:
+
+- [src/services/db/address.db.ts](src/services/db/address.db.ts)
+- [src/services/db/address.db.test.ts](src/services/db/address.db.test.ts)
+
+---
+
+### Phase 2: TypeScript Types & Validation
+
+#### 2.1 Add Extended Types ([src/types.ts](src/types.ts))
+
+```typescript
+// Store with address data for API responses
+export interface StoreWithLocation {
+  ...Store;
+  locations: Array<{
+    store_location_id: number;
+    address: Address;
+  }>;
+}
+
+// For API requests when creating store
+export interface CreateStoreRequest {
+  name: string;
+  logo_url?: string;
+  address?: {
+    address_line_1: string;
+    city: string;
+    province_state: string;
+    postal_code: string;
+    country?: string;
+  };
+}
+```
+
+#### 2.2 Add Zod Validation Schemas
+
+Create [src/schemas/store.schema.ts](src/schemas/store.schema.ts):
+
+- `createStoreSchema` - Validates POST /stores body
+- `updateStoreSchema` - Validates PUT /stores/:id body
+- `addLocationSchema` - Validates POST /stores/:id/locations body
+
+---
+
+### Phase 3: API Routes
+
+#### 3.1 Create Store Routes ([src/routes/store.routes.ts](src/routes/store.routes.ts))
+
+Endpoints:
+
+- `GET /api/stores` - List all stores (with pagination)
+  - Query params: `?includeLocations=true`, `?search=name`
+- `GET /api/stores/:id` - Get single store with locations
+- `POST /api/stores` - Create store (optionally with address)
+- `PUT /api/stores/:id` - Update store name/logo
+- `DELETE /api/stores/:id` - Delete store (admin only)
+- `POST /api/stores/:id/locations` - Add location to store
+- `DELETE /api/stores/:id/locations/:locationId` - Remove location
+
+**Test file**: [src/routes/store.routes.test.ts](src/routes/store.routes.test.ts)
+
+**Permissions**:
+
+- Create/Update/Delete: Admin only
+- Read: Public (for store listings in flyers/deals)
+
+#### 3.2 Update Existing Routes to Include Address Data
+
+**Files to modify**:
+
+- [src/routes/flyer.routes.ts](src/routes/flyer.routes.ts) - GET /flyers should include store address
+- [src/routes/deals.routes.ts](src/routes/deals.routes.ts) - GET /deals should include store address
+- [src/routes/receipt.routes.ts](src/routes/receipt.routes.ts) - GET /receipts/:id should include store address
+
+---
+
+### Phase 4: Update Database Queries
+
+#### 4.1 Modify Existing Queries to JOIN Addresses
+
+**Files to modify**:
+
+- [src/services/db/admin.db.ts](src/services/db/admin.db.ts)
+  - Line 334: JOIN store_locations and addresses for unmatched items
+  - Line 720: JOIN store_locations and addresses for flyers needing review
+
+- [src/services/db/flyer.db.ts](src/services/db/flyer.db.ts)
+  - Any query that returns flyers with store data
+
+- [src/services/db/deals.db.ts](src/services/db/deals.db.ts)
+  - Add address fields to deal queries
+
+**Pattern to use**:
+
+```sql
+SELECT
+  s.*,
+  json_agg(
+    json_build_object(
+      'store_location_id', sl.store_location_id,
+      'address', row_to_json(a.*)
+    )
+  ) FILTER (WHERE sl.store_location_id IS NOT NULL) as locations
+FROM stores s
+LEFT JOIN store_locations sl ON s.store_id = sl.store_id
+LEFT JOIN addresses a ON sl.address_id = a.address_id
+GROUP BY s.store_id
+```
+
+---
+
+### Phase 5: Frontend Components
+
+#### 5.1 Admin Store Management
+
+Create [src/pages/admin/components/AdminStoreManager.tsx](src/pages/admin/components/AdminStoreManager.tsx):
+
+- Table listing all stores with locations
+- Create store button → opens modal/form
+- Edit store button → opens modal with store+address data
+- Delete store button (with confirmation)
+
+#### 5.2 Store Form Component
+
+Create [src/features/store/StoreForm.tsx](src/features/store/StoreForm.tsx):
+
+- Store name input
+- Logo URL input
+- Address section:
+  - Address line 1 (required)
+  - City (required)
+  - Province/State (required)
+  - Postal code (required)
+  - Country (default: Canada)
+- Reusable for create & edit
+
+#### 5.3 Store Display Components
+
+Create [src/features/store/StoreCard.tsx](src/features/store/StoreCard.tsx):
+
+- Shows store name + logo
+- Shows primary address (if exists)
+- "View all locations" link (if multiple)
+
+Update existing components to use StoreCard:
+
+- Flyer listings
+- Deal listings
+- Receipt displays
+
+#### 5.4 Location Selector Component
+
+Create [src/features/store/LocationSelector.tsx](src/features/store/LocationSelector.tsx):
+
+- Dropdown or map view
+- Filter stores by proximity (future: use lat/long)
+- Used in "Find deals near me" feature
+
+---
+
+### Phase 6: Update Integration Tests
+
+All integration tests that create stores need to use `createStoreWithLocation()`:
+
+**Files to update** (5 files):
+
+1. [src/tests/integration/admin.integration.test.ts](src/tests/integration/admin.integration.test.ts) (line 164)
+2. [src/tests/integration/flyer.integration.test.ts](src/tests/integration/flyer.integration.test.ts) (line 28)
+3. [src/tests/integration/price.integration.test.ts](src/tests/integration/price.integration.test.ts) (line 48)
+4. [src/tests/integration/public.routes.integration.test.ts](src/tests/integration/public.routes.integration.test.ts) (line 66)
+5. [src/tests/integration/receipt.integration.test.ts](src/tests/integration/receipt.integration.test.ts) (line 252)
+
+**Change pattern**:
+
+```typescript
+// OLD:
+const storeResult = await pool.query('INSERT INTO stores (name) VALUES ($1) RETURNING store_id', [
+  'Test Store',
+]);
+
+// NEW:
+import { createStoreWithLocation } from '../utils/storeHelpers';
+const store = await createStoreWithLocation(pool, {
+  name: 'Test Store',
+  address: '123 Test St',
+  city: 'Test City',
+  province: 'ON',
+  postalCode: 'M5V 1A1',
+});
+const storeId = store.storeId;
+```
+
+---
+
+### Phase 7: Update Unit Tests & Mocks
+
+#### 7.1 Update Mock Factories
+
+[src/tests/utils/mockFactories.ts](src/tests/utils/mockFactories.ts) - Add:
+
+- `createMockStore(overrides?): Store`
+- `createMockAddress(overrides?): Address`
+- `createMockStoreLocation(overrides?): StoreLocation`
+- `createMockStoreWithLocation(overrides?): StoreWithLocation`
+
+#### 7.2 Update Component Tests
+
+Files that display stores need updated mocks:
+
+- [src/features/flyer/FlyerDisplay.test.tsx](src/features/flyer/FlyerDisplay.test.tsx)
+- [src/features/flyer/FlyerList.test.tsx](src/features/flyer/FlyerList.test.tsx)
+- Any other components that show store data
+
+---
+
+### Phase 8: Schema Migration (IF NEEDED)
+
+**Check**: Do we need to migrate existing data?
+
+- If production has stores without addresses, we need to handle this
+- Options:
+  1. Make addresses optional (store can exist without location)
+  2. Create "Unknown Location" placeholder addresses
+  3. Manual data entry for existing stores
+
+**Migration file**: [sql/migrations/XXX_add_store_locations_data.sql](sql/migrations/XXX_add_store_locations_data.sql) (if needed)
+
+---
+
+### Phase 9: Documentation & Cache Invalidation
+
+#### 9.1 Update API Documentation
+
+- Add store endpoints to API docs
+- Document request/response formats
+- Add examples
+
+#### 9.2 Cache Invalidation
+
+[src/services/cacheService.server.ts](src/services/cacheService.server.ts):
+
+- Add `invalidateStores()` method
+- Add `invalidateStoreLocations(storeId)` method
+- Call after create/update/delete operations
+
+---
+

+12. `STORE_ADDRESS_IMPLEMENTATION_PLAN.md` - This document
+
+### Files to Modify (20+ files):
+
+**Database Layer (3)**:
+
+- `src/services/db/address.db.ts` - Add search functions
+- `src/services/db/admin.db.ts` - Update JOINs
+- `src/services/db/flyer.db.ts` - Update JOINs

+
+- `src/routes/flyer.routes.ts` - Include address in responses
+- `src/routes/deals.routes.ts` - Include address in responses
+- `src/routes/receipt.routes.ts` - Include address in responses
+
+**Types (1)**:

+
+**Tests (10+)**:
+
+- `src/tests/integration/admin.integration.test.ts`
+- `src/tests/integration/flyer.integration.test.ts`
+- `src/tests/integration/price.integration.test.ts`
+- `src/tests/integration/public.routes.integration.test.ts`

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

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