+# ADR-023: Database Normalization and Referential Integrity
+
+**Date:** 2026-01-19
+**Status:** Accepted
+**Context:** API design violates database normalization principles
+
+## Problem Statement
+
+The application's API layer currently accepts string-based references (category names) instead of numerical IDs when creating relationships between entities. This violates database normalization principles and creates a brittle, error-prone API contract.
+
+**Example of Current Problem:**
+
+```typescript
+// API accepts string:
+POST /api/users/watched-items
+{ "itemName": "Milk", "category": "Dairy & Eggs" }  // ❌ String reference
+
+// But database uses normalized foreign keys:
+CREATE TABLE master_grocery_items (
+  category_id BIGINT REFERENCES categories(category_id)  -- ✅ Proper FK
+)
+```
+
+This mismatch forces the service layer to perform string lookups on every request:
+
+```typescript
+// Service must do string matching:
+const categoryRes = await client.query(
+  'SELECT category_id FROM categories WHERE name = $1',
+  [categoryName], // ❌ Error-prone string matching
+);
+```
+
+## Database Normal Forms (In Order of Importance)
+
+### 1. First Normal Form (1NF) ✅ Currently Satisfied
+
+**Rule:** Each column contains atomic values; no repeating groups.
+
+**Status:** ✅ **Compliant**
+
+- All columns contain single values
+- No arrays or delimited strings in columns
+- Each row is uniquely identifiable
+
+**Example:**
+
+```sql
+-- ✅ Good: Atomic values
+CREATE TABLE master_grocery_items (
+  master_grocery_item_id BIGINT PRIMARY KEY,
+  name TEXT,
+  category_id BIGINT
+);
+
+-- ❌ Bad: Non-atomic values (violates 1NF)
+CREATE TABLE items (
+  id BIGINT,
+  categories TEXT  -- "Dairy,Frozen,Snacks" (comma-delimited)
+);
+```
+
+### 2. Second Normal Form (2NF) ✅ Currently Satisfied
+
+**Rule:** No partial dependencies; all non-key columns depend on the entire primary key.
+
+**Status:** ✅ **Compliant**
+
+- All tables use single-column primary keys (no composite keys)
+- All non-key columns depend on the entire primary key
+
+**Example:**
+
+```sql
+-- ✅ Good: All columns depend on full primary key
+CREATE TABLE flyer_items (
+  flyer_item_id BIGINT PRIMARY KEY,
+  flyer_id BIGINT,           -- Depends on flyer_item_id
+  master_item_id BIGINT,     -- Depends on flyer_item_id
+  price_in_cents INT         -- Depends on flyer_item_id
+);
+
+-- ❌ Bad: Partial dependency (violates 2NF)
+CREATE TABLE flyer_items (
+  flyer_id BIGINT,
+  item_id BIGINT,
+  store_name TEXT,    -- Depends only on flyer_id, not (flyer_id, item_id)
+  PRIMARY KEY (flyer_id, item_id)
+);
+```
+
+### 3. Third Normal Form (3NF) ⚠️ VIOLATED IN API LAYER
+
+**Rule:** No transitive dependencies; non-key columns depend only on the primary key, not on other non-key columns.
+
+**Status:** ⚠️ **Database is compliant, but API layer violates this principle**
+
+**Database Schema (Correct):**
+
+```sql
+-- ✅ Categories are normalized
+CREATE TABLE categories (
+  category_id BIGINT PRIMARY KEY,
+  name TEXT NOT NULL UNIQUE
+);
+
+CREATE TABLE master_grocery_items (
+  master_grocery_item_id BIGINT PRIMARY KEY,
+  name TEXT,
+  category_id BIGINT REFERENCES categories(category_id)  -- Direct reference
+);
+```
+
+**API Layer (Violates 3NF Principle):**
+
+```typescript
+// ❌ API accepts category name instead of ID
+POST /api/users/watched-items
+{
+  "itemName": "Milk",
+  "category": "Dairy & Eggs"  // String! Should be category_id
+}
+
+// Service layer must denormalize by doing lookup:
+SELECT category_id FROM categories WHERE name = $1
+```
+
+This creates a **transitive dependency** in the application layer:
+
+- `watched_item` → `category_name` → `category_id`
+- Instead of direct: `watched_item` → `category_id`
+
+### 4. Boyce-Codd Normal Form (BCNF) ✅ Currently Satisfied
+
+**Rule:** Every determinant is a candidate key (stricter version of 3NF).
+
+**Status:** ✅ **Compliant**
+
+- All foreign key references use primary keys
+- No non-trivial functional dependencies where determinant is not a superkey
+
+### 5. Fourth Normal Form (4NF) ✅ Currently Satisfied
+
+**Rule:** No multi-valued dependencies; a record should not contain independent multi-valued facts.
+
+**Status:** ✅ **Compliant**
+
+- Junction tables properly separate many-to-many relationships
+- Examples: `user_watched_items`, `shopping_list_items`, `recipe_ingredients`
+
+### 6. Fifth Normal Form (5NF) ✅ Currently Satisfied
+
+**Rule:** No join dependencies; tables cannot be decomposed further without loss of information.
+
+**Status:** ✅ **Compliant** (as far as schema design goes)
+
+## Impact of API Violation
+
+### 1. Brittleness
+
+```typescript
+// Test fails because of exact string matching:
+addWatchedItem('Milk', 'Dairy'); // ❌ Fails - not exact match
+addWatchedItem('Milk', 'Dairy & Eggs'); // ✅ Works - exact match
+addWatchedItem('Milk', 'dairy & eggs'); // ❌ Fails - case sensitive
+```
+
+### 2. No Discovery Mechanism
+
+- No API endpoint to list available categories
+- Frontend cannot dynamically populate dropdowns
+- Clients must hardcode category names
+
+### 3. Performance Penalty
+
+```sql
+-- Current: String lookup on every request
+SELECT category_id FROM categories WHERE name = $1;  -- Full table scan or index scan
+
+-- Should be: Direct ID reference (no lookup needed)
+INSERT INTO master_grocery_items (name, category_id) VALUES ($1, $2);
+```
+
+### 4. Impossible Localization
+
+- Cannot translate category names without breaking API
+- Category names are hardcoded in English
+
+### 5. Maintenance Burden
+
+- Renaming a category breaks all API clients
+- Must coordinate name changes across frontend, tests, and documentation
+
+## Decision
+
+**We adopt the following principles for all API design:**
+
+### 1. Use Numerical IDs for All Foreign Key References
+
+**Rule:** APIs MUST accept numerical IDs when creating relationships between entities.
+
+```typescript
+// ✅ CORRECT: Use IDs
+POST /api/users/watched-items
+{
+  "itemName": "Milk",
+  "category_id": 3  // Numerical ID
+}
+
+// ❌ INCORRECT: Use strings
+POST /api/users/watched-items
+{
+  "itemName": "Milk",
+  "category": "Dairy & Eggs"  // String name
+}
+```
+
+### 2. Provide Discovery Endpoints
+
+**Rule:** For any entity referenced by ID, provide a GET endpoint to list available options.
+
+```typescript
+// Required: Category discovery endpoint
+GET / api / categories;
+Response: [
+  { category_id: 1, name: 'Fruits & Vegetables' },
+  { category_id: 2, name: 'Meat & Seafood' },
+  { category_id: 3, name: 'Dairy & Eggs' },
+];
+```
+
+### 3. Support Lookup by Name (Optional)
+
+**Rule:** If convenient, provide query parameters for name-based lookup, but use IDs internally.
+
+```typescript
+// Optional: Convenience endpoint
+GET /api/categories?name=Dairy%20%26%20Eggs
+Response: { "category_id": 3, "name": "Dairy & Eggs" }
+```
+
+### 4. Return Full Objects in Responses
+
+**Rule:** API responses SHOULD include denormalized data for convenience, but inputs MUST use IDs.
+
+```typescript
+// ✅ Response includes category details
+GET / api / users / watched - items;
+Response: [
+  {
+    master_grocery_item_id: 42,
+    name: 'Milk',
+    category_id: 3,
+    category: {
+      // ✅ Include full object in response
+      category_id: 3,
+      name: 'Dairy & Eggs',
+    },
+  },
+];
+```
+
+## Affected Areas
+
+### Immediate Violations (Must Fix)
+
+1. **User Watched Items** ([src/routes/user.routes.ts:76](../../src/routes/user.routes.ts))
+   - Currently: `category: string`
+   - Should be: `category_id: number`
+
+2. **Service Layer** ([src/services/db/personalization.db.ts:175](../../src/services/db/personalization.db.ts))
+   - Currently: `categoryName: string`
+   - Should be: `categoryId: number`
+
+3. **API Client** ([src/services/apiClient.ts:436](../../src/services/apiClient.ts))
+   - Currently: `category: string`
+   - Should be: `category_id: number`
+
+4. **Frontend Hooks** ([src/hooks/mutations/useAddWatchedItemMutation.ts:9](../../src/hooks/mutations/useAddWatchedItemMutation.ts))
+   - Currently: `category?: string`
+   - Should be: `category_id: number`
+
+### Potential Violations (Review Required)
+
+1. **UPC/Barcode System** ([src/types/upc.ts:85](../../src/types/upc.ts))
+   - Uses `category: string | null`
+   - May be appropriate if category is free-form user input
+
+2. **AI Extraction** ([src/types/ai.ts:21](../../src/types/ai.ts))
+   - Uses `category_name: z.string()`
+   - AI extracts category names, needs mapping to IDs
+
+3. **Flyer Data Transformer** ([src/services/flyerDataTransformer.ts:40](../../src/services/flyerDataTransformer.ts))
+   - Uses `category_name: string`
+   - May need category matching/creation logic
+
+## Migration Strategy
+
+See [research-category-id-migration.md](../research-category-id-migration.md) for detailed migration plan.
+
+**High-level approach:**
+
+1. **Phase 1: Add category discovery endpoint** (non-breaking)
+   - `GET /api/categories`
+   - No API changes yet
+
+2. **Phase 2: Support both formats** (non-breaking)
+   - Accept both `category` (string) and `category_id` (number)
+   - Deprecate string format with warning logs
+
+3. **Phase 3: Remove string support** (breaking change, major version bump)
+   - Only accept `category_id`
+   - Update all clients and tests
+
+## Consequences
+
+### Positive
+
+- ✅ API matches database schema design
+- ✅ More robust (no typo-based failures)
+- ✅ Better performance (no string lookups)
+- ✅ Enables localization
+- ✅ Discoverable via REST API
+- ✅ Follows REST best practices
+
+### Negative
+
+- ⚠️ Breaking change for existing API consumers
+- ⚠️ Requires client updates
+- ⚠️ More complex migration path
+
+### Neutral
+
+- Frontend must fetch categories before displaying form
+- Slightly more initial API calls (one-time category fetch)

+# Research: Separating E2E Tests from Integration Tests
+
+**Date:** 2026-01-19
+**Status:** In Progress
+**Context:** E2E tests exist with their own config but are not being run separately
+
+## Current State
+
+### Test Structure
+
+- **Unit tests**: `src/tests/unit/` (but most are co-located with source files)
+- **Integration tests**: `src/tests/integration/` (28 test files)
+- **E2E tests**: `src/tests/e2e/` (11 test files) **← NOT CURRENTLY RUNNING**
+
+### Configurations
+
+| Config File                    | Project Name  | Environment | Port | Include Pattern                            |
+| ------------------------------ | ------------- | ----------- | ---- | ------------------------------------------ |
+| `vite.config.ts`               | `unit`        | jsdom       | N/A  | Component/hook tests                       |
+| `vitest.config.integration.ts` | `integration` | node        | 3099 | `src/tests/integration/**/*.test.{ts,tsx}` |
+| `vitest.config.e2e.ts`         | `e2e`         | node        | 3098 | `src/tests/e2e/**/*.e2e.test.ts`           |
+
+### Workspace Configuration
+
+**`vitest.workspace.ts` currently includes:**
+
+```typescript
+export default [
+  'vite.config.ts', // Unit tests
+  'vitest.config.integration.ts', // Integration tests
+  // ❌ vitest.config.e2e.ts is NOT included!
+];
+```
+
+### NPM Scripts
+
+```json
+{
+  "test": "node scripts/check-linux.js && cross-env NODE_ENV=test tsx ./node_modules/vitest/vitest.mjs run",
+  "test:unit": "... --project unit ...",
+  "test:integration": "... --project integration ..."
+  // ❌ NO test:e2e script exists!
+}
+```
+
+### CI/CD Status
+
+**`.gitea/workflows/deploy-to-test.yml` runs:**
+
+- ✅ `npm run test:unit -- --coverage`
+- ✅ `npm run test:integration -- --coverage`
+- ❌ E2E tests are NOT run in CI
+
+## Key Findings
+
+### 1. E2E Tests Are Orphaned
+
+- 11 E2E test files exist but are never executed
+- E2E config file exists (`vitest.config.e2e.ts`) but is not referenced anywhere
+- No npm script to run E2E tests
+- Not included in vitest workspace
+- Not run in CI/CD pipeline
+
+### 2. When Were E2E Tests Created?
+
+Git history shows E2E config was added in commit `e66027d` ("fix e2e and deploy to prod"), but:
+
+- It was never added to the workspace
+- It was never added to CI
+- No test:e2e script was created
+
+This suggests the E2E separation was **started but never completed**.
+
+### 3. How Are Tests Currently Run?
+
+**Locally:**
+
+- `npm test` → runs workspace (unit + integration only)
+- `npm run test:unit` → runs only unit tests
+- `npm run test:integration` → runs only integration tests
+- E2E tests: **Not accessible via any command**
+
+**In CI:**
+
+- Only `test:unit` and `test:integration` are run
+- E2E tests are never executed
+
+### 4. Port Allocation
+
+- Integration tests: Port 3099
+- E2E tests: Port 3098 (configured but never used)
+- No conflicts if both run sequentially
+
+## E2E Test Files (11 total)
+
+1. `admin-authorization.e2e.test.ts`
+2. `admin-dashboard.e2e.test.ts`
+3. `auth.e2e.test.ts`
+4. `budget-journey.e2e.test.ts`
+5. `deals-journey.e2e.test.ts` ← Just fixed URL constraint issue
+6. `error-reporting.e2e.test.ts`
+7. `flyer-upload.e2e.test.ts`
+8. `inventory-journey.e2e.test.ts`
+9. `receipt-journey.e2e.test.ts`
+10. `upc-journey.e2e.test.ts`
+11. `user-journey.e2e.test.ts`
+
+## Problems to Solve
+
+### Immediate Issues
+
+1. **E2E tests are not running** - Code exists but is never executed
+2. **No way to run E2E tests** - No npm script or CI job
+3. **Coverage gaps** - E2E scenarios are untested in practice
+4. **False sense of security** - Team may think E2E tests are running
+
+### Implementation Challenges
+
+#### 1. Adding E2E to Workspace
+
+**Option A: Add to workspace**
+
+```typescript
+// vitest.workspace.ts
+export default [
+  'vite.config.ts',
+  'vitest.config.integration.ts',
+  'vitest.config.e2e.ts', // ← Add this
+];
+```
+
+**Impact:** E2E tests would run with `npm test`, increasing test time significantly
+
+**Option B: Keep separate**
+
+- E2E remains outside workspace
+- Requires explicit `npm run test:e2e` command
+- CI would need separate step for E2E tests
+
+#### 2. Adding NPM Script
+
+```json
+{
+  "test:e2e": "node scripts/check-linux.js && cross-env NODE_ENV=test tsx --max-old-space-size=8192 ./node_modules/vitest/vitest.mjs run --project e2e -c vitest.config.e2e.ts"
+}
+```
+
+**Dependencies:**
+
+- Uses same global setup pattern as integration tests
+- Requires server to be stopped first (like integration tests)
+- Port 3098 must be available
+
+#### 3. CI/CD Integration
+
+**Add to `.gitea/workflows/deploy-to-test.yml`:**
+
+```yaml
+- name: Run E2E Tests
+  run: |
+    npm run test:e2e -- --coverage \
+      --reporter=verbose \
+      --includeTaskLocation \
+      --testTimeout=120000 \
+      --silent=passed-only
+```
+
+**Questions:**
+
+- Should E2E run before or after integration tests?
+- Should E2E failures block deployment?
+- Should E2E have separate coverage reports?
+
+#### 4. Test Organization Questions
+
+- Are current "integration" tests actually E2E tests?
+- Should some E2E tests be moved to integration?
+- What's the distinction between integration and E2E in this project?
+
+#### 5. Coverage Implications
+
+- E2E tests have separate coverage directory: `.coverage/e2e`
+- Integration tests: `.coverage/integration`
+- How to merge coverage from all test types?
+- Do we need combined coverage reports?
+
+## Recommended Approach
+
+### Phase 1: Quick Fix (Enable E2E Tests)
+
+1. ✅ Fix any failing E2E tests (like URL constraints)
+2. Add `test:e2e` npm script
+3. Document how to run E2E tests manually
+4. Do NOT add to workspace yet (keep separate)
+
+### Phase 2: CI Integration
+
+1. Add E2E test step to `.gitea/workflows/deploy-to-test.yml`
+2. Run after integration tests pass
+3. Allow failures initially (monitor results)
+4. Make blocking once stable
+
+### Phase 3: Optimize
+
+1. Review test categorization (integration vs E2E)
+2. Consider adding to workspace if test time is acceptable
+3. Merge coverage reports if needed
+4. Document test strategy in testing docs
+
+## Next Steps
+
+1. **Create `test:e2e` script** in package.json
+2. **Run E2E tests manually** to verify they work
+3. **Fix any failing E2E tests**
+4. **Document E2E testing** in TESTING.md
+5. **Add to CI** once stable
+6. **Consider workspace integration** after CI is stable
+
+## Questions for Team
+
+1. Why were E2E tests never fully integrated?
+2. Should E2E tests run on every commit or separately?
+3. What's the acceptable test time for local development?
+4. Should we run E2E tests in parallel or sequentially with integration?
