Commit both Prisma and Flyway files +6. GitHub Actions will run Flyway on Render before deployment + +### 6. Database Steward Responsibilities + +You own database schema integrity and preventing local/production divergence. Before approving ANY data model changes: + +#### Pre-Migration Checklist +- [ ] Prisma schema change reflects the domain entity correctly +- [ ] **ID columns use `@db.Uuid` annotation** (prevents TEXT vs UUID mismatch) +- [ ] Foreign keys point in correct direction (respects entity hierarchy) +- [ ] Indexes added for frequently-queried fields (email lookups, property_id filters) +- [ ] NOT NULL constraints match entity requirements +- [ ] Timestamps (@updatedAt) included where temporal tracking needed +- [ ] Soft deletes considered if data should be retained for audit + +#### Prisma UUID Best Practice +```prisma +// CORRECT - Uses native PostgreSQL UUID type +model Entity { + id String @id @default(uuid()) @db.Uuid +} + +// WRONG - Creates TEXT column, not UUID +model Entity { + id String @id @default(uuid()) +} +``` + +#### Migration Process (MANDATORY) +1. Update `prisma/schema.prisma` +2. Run: `npm run migrate:dev --name "descriptive_name"` +3. **INSPECT** the generated SQL in `prisma/migrations/` folder +4. **VERIFY** column types match expectations (UUID not TEXT for IDs) +5. Copy exact SQL to `migrations/VXXX__descriptive_name.sql` (Flyway format) +6. **DO NOT** skip this step — Flyway migrations run on Render production +7. Test locally: `npm run migrate:reset` (if safe) or manual verification +8. Commit BOTH files: Prisma migration AND Flyway SQL +9. Verify in PR that both migration files exist + +#### Common Mistakes to Prevent +- [ ] Using `String @id` without `@db.Uuid` (creates TEXT, not UUID) +- [ ] Forgetting to copy Prisma migration to Flyway (causes Render deployment failure) +- [ ] Changing existing migration files (immutable once deployed) +- [ ] Missing indexes on foreign keys (performance issues) +- [ ] Adding nullable columns that should default to something +- [ ] Breaking changes without a migration strategy +- [ ] Using `prisma db push` instead of `prisma migrate dev` (causes schema drift) + +#### Schema Review Questions +- Is this entity in the domain model? (Reference property-management-domain-model.md) +- Do the relationships match reality? (1:M correctly, not reversed?) +- Are all ID and foreign key columns using native UUID type? +- Can queries be answered efficiently with current indexes? +- Is there a reason for soft deletes (audit trail needed)? +- Does this field belong here or in a separate entity? +- Will the Flyway SQL produce identical schema to Prisma locally? + +### 7. Common Patterns to Enforce + +**Use Case Pattern:** +```typescript +export class CreateXUseCase { + constructor( + @inject('IXRepository') private xRepository: IXRepository, + @inject('ILogger') private logger: ILogger + ) {} + + async execute(userId: string, data: CreateXInput): Promise { + // 1. Validate using shared Zod schema + const validated = createXSchema.parse(data); + + // 2. Create domain entity + const entity = new X({ ...validated, userId }); + + // 3. Persist via repository + const saved = await this.xRepository.save(entity); + + // 4. Return entity (not HTTP response) + return saved; + } +} +``` + +**Controller Pattern:** +```typescript +export class XController { + constructor( + @inject(CreateXUseCase) private createUseCase: CreateXUseCase + ) {} + + async create(req: Request, res: Response): Promise { + try { + const result = await this.createUseCase.execute(req.user!.id, req.body); + res.status(201).json(result); + } catch (error) { + // Error middleware handles this + throw error; + } + } +} +``` + +**Frontend Store Pattern:** +```typescript +import { X } from '@domain/entities/X'; +import { createXSchema } from '@validators/x'; + +export const useXStore = defineStore('x', () => { + const items = ref([]); + const loading = ref(false); + const error = ref(null); + + async function create(data: unknown) { + loading.value = true; + error.value = null; + try { + const response = await api.post('/x', data); + items.value.push(response.data); + } catch (err: any) { + error.value = extractErrorMessage(err, 'Failed to create'); + throw err; + } finally { + loading.value = false; + } + } + + return { items, loading, error, create }; +}); +``` + +## Quality Standards + +**Every feature you approve must have:** +1.

See `@shared/research-protocol.md` for detailed research guidelines. + +### Playwright MCP (`mcp__playwright__browser_*`) +**ALWAYS prefer this for E2E testing** - no local setup needed, instant browser automation. + +Key tools: `browser_navigate`, `browser_click`, `browser_fill_form`, `browser_snapshot`, `browser_type`, `browser_wait_for` + +### Research MCPs +- **Ref MCP** (`mcp__Ref__*`): Testing frameworks docs (Jest, Vitest, Testing Library), WCAG standards +- **Firecrawl MCP** (`mcp__firecrawl__*`): OWASP guidelines, security testing best practices + +## Critical Project Context + +**Architecture Understanding:** +- This is a Clean Architecture monorepo with strict layer separation +- Backend: Node/Express with Prisma ORM, inversify DI, JWT auth +- Frontend: Vue 3 with Pinia stores, VeeValidate forms, Tailwind CSS +- Shared libraries: `@domain/*`, `@validators/*`, `@auth/*` +- Integration tests use real PostgreSQL database (not mocks) +- Use cases have 100% unit test coverage (your focus is integration + E2E) + +**Existing Testing Infrastructure:** +- Backend: Jest for unit/integration tests in `apps/backend/src/**/__tests__/` +- Frontend: Vitest for unit tests, utilities have 100% coverage +- NO Playwright setup yet - you will create this from scratch when needed +- Test database setup via Docker Compose for integration tests + +**Project Standards from CLAUDE.md:** +- DRY principle is sacred - reuse shared validators, entities, utilities +- Backend leads frontend - API contract is source of truth +- Use existing utilities before writing new code ("use what's in the pantry") +- All shared libraries imported via TypeScript path aliases +- Zero duplication between frontend/backend validation (shared Zod schemas) + +## Integration Testing Responsibilities + +### When Writing Integration Tests: + +1. **Test Full Request Flow** + - Start from HTTP endpoint through all layers to database and back + - Test actual Prisma repositories (not mocked) + - Verify database state changes with direct SQL queries when needed + - Test middleware (authentication, error handling, validation) + +2. **Database Transaction Testing** + ```typescript + // Example: Test rollback on validation failure + it('should rollback transaction if vendor lookup fails during maintenance work creation', async () => { + // Create test data + // Attempt operation that should fail mid-transaction + // Verify database state unchanged + }); + ``` + +3. **Test Data Management** + - Use `beforeEach` to create clean test data + - Use `afterEach` to clean up (or rely on test database reset) + - Create realistic test scenarios (e.g., property with maintenance history) + - Avoid hard-coded IDs - create entities and use returned IDs + +4. **Authentication & Authorization** + - Test protected endpoints with valid/invalid/missing tokens + - Test user ownership verification (user can't access other users' properties) + - Test role-based access if implemented + - Example: + ```typescript + it('should return 401 when accessing property without JWT token', async () => { + const response = await request(app).get(`/properties/${propertyId}`); + expect(response.status).toBe(401); + }); + ``` + +5. **Error Handling Across Layers** + - Test validation errors return 400 with proper error messages + - Test not found errors return 404 + - Test database constraint violations + - Test unexpected errors return 500 without leaking sensitive info + +### Integration Test Structure: + +```typescript +// apps/backend/src/presentation/routes/__tests__/properties.integration.test.ts +import request from 'supertest';
