Complete vertical pipeline following Constitution 2.0.0 Pipeline: BDD API Domain Application Infra Controllers Frontend Contracts E2E CI/CD Each phase includes exact locations, artifacts, criteria, prohibitions, and gates Coverage minimums: Domain 90%, App 80%, Controllers 80%, FE 70% Estimated effort: 8-10 developer days
- Phase 1: Created all project directories with .gitkeep files - Backend: domain, application, infrastructure packages - Tests: BDD, contracts, e2e structures - Frontend: api, components, pages, hooks, state directories - Phase 2: BDD First (YELLOW state achieved) - compose-content.feature: 8 consolidated scenarios - ComposeContentSteps.java: All step definitions with PendingException - ComposeContentBDDTest.java: JUnit Platform runner - Tests run: 8, Errors: 8 (PendingException - YELLOW ) - Verified all scenarios execute and show PENDING status - Fixed pom.xml testSourceDirectory (Maven standard) - Commented cucumber-spring dependency (not needed for YELLOW phase) Next: Phase 3 - API First (OpenAPI definition)
- Created complete OpenAPI 3.0.3 specification - File: compose-content.yaml (650+ lines) - 11 operations covering 8 core capabilities: 1. createComposition Scenario 1 (Access Builder) 2. updateText Scenario 2 (Manual Text Entry) 3. generateText Scenario 3 (AI Text Gen/Enhancement) 4. generateImage Scenario 4 (AI Image Generation) 5. getOutputType Scenarios 5 & 6 (Output Type) 6. previewMusic Scenario 7 (Music Preview) 7. previewImage Scenario 8 (Image Preview) + selectMusic, setImage, removeImage, getComposition - Request/Response schemas: 11 DTOs defined - Error handling: 400, 404, 429, 503, 500 responses - All operationIds aligned with use case names - Capabilities mapped to BDD scenarios in comments - YAML structure validated (openapi 3.0.3 compliant) - Added comprehensive .gitignore: - Maven target/ directory excluded - Node modules, build artifacts excluded - Test reports, coverage excluded - IDE files, OS temp files excluded Next: Phase 4 - Domain Layer (Value Objects, Entities, Ports)
…(T015-T025) **Value Objects Created** (Immutable, TDD): - TextContent: Meditation text with preservation invariant (10k char max) - 10 unit tests: validation, immutability, value equality - OutputType: PODCAST vs VIDEO enum - 5 unit tests: enum values, valueOf - MusicReference: Optional music catalog reference - 6 unit tests: validation, value equality - ImageReference: Optional image reference (manual/AI) - 7 unit tests: validation, value equality **Aggregate Root Created**: - MeditationComposition: Core domain entity - Business logic: getOutputType() (image == null PODCAST, else VIDEO) - 15 unit tests: creation, updates, output type derivation - Enforces invariants: ID required, TextContent mandatory **Inbound Ports (Use Cases)**: - ComposeContentUseCase: 7 methods (create, update, select, set, remove, get) - GenerateTextUseCase: generateText(), enhanceText() - GenerateImageUseCase: generateImage() **Outbound Ports (External Services)**: - MediaCatalogPort: music/image catalog access (preview, validation) - TextGenerationPort: AI text generation service - ImageGenerationPort: AI image generation service **Tests Summary**: - 43 domain unit tests PASSING (100% coverage) - Zero framework dependencies (pure Java) - DDD invariants enforced - BDD still YELLOW (8 scenarios pending - expected) **Fixed**: - .gitignore: Changed 'out/' to '/out/' (excluded IntelliJ root, not ports/out/) Next: Phase 5 - Application Layer (Use Case Services)
**Patrón aplicado:** Siguiendo MeditationComposition.java **Value Objects refactorizados:** TextContent.java: final class record MusicReference.java: final class record ImageReference.java: final class record **Cambios implementados:** - Constructor compacto con validación (Objects.requireNonNull) - Eliminados getters manuales (getValue() value() auto-generado) - Eliminados equals/hashCode/toString (auto-generados por record) - Inmutabilidad garantizada por record - Validaciones preservadas en constructor canónico compacto - TextContent mantiene helper method length() **Tests actualizados:** - TextContentTest: 10 tests adaptados a record accessor value() - MusicReferenceTest: 6 tests adaptados - ImageReferenceTest: 7 tests adaptados - MeditationCompositionTest: 18 tests reescritos para API inmutable - Uso de factory methods create() - Tests de Clock injection - Tests de inmutabilidad (withX retorna nuevas instancias) - Tests de timestamps (createdAt/updatedAt) - Tests de Optional accessors - Tests de operaciones encadenadas **Diferencias con old API:** - getValue() value() (convención records) - NullPointerException esperada (Objects.requireNonNull) - Immutable API: withText(), withMusic(), withImage() retornan nuevas instancias **Tests Summary:** - 46 domain tests PASSING (100% coverage) - OutputTypeTest: 5 tests - ImageReferenceTest: 7 tests - MeditationCompositionTest: 18 tests - MusicReferenceTest: 6 tests - TextContentTest: 10 tests - BDD: 8 scenarios YELLOW (pending - esperado) Next: FASE 2 - Actualizar ComposeContentUseCase a UUID
**Breaking Change:** Port signature actualizado **Cambios:** ComposeContentUseCase.java: String compositionId UUID compositionId - updateText(UUID, ...) - selectMusic(UUID, ...) - setImage(UUID, ...) - removeImage(UUID) - getOutputType(UUID) - getComposition(UUID) - CompositionNotFoundException(UUID) constructor **Justificación:** - Alineado con MeditationComposition record (usa UUID id) - Tipo seguro evita errores de casting - Mejor semántica de dominio (UUID es identifier, String es text) **Impacto:** Application Layer (Phase 5): servicios deben actualizar firmas Infrastructure Controllers (Phase 7): parsear UUID de path params DTOs (Phase 7): mapear String UUID OpenAPI (ya tiene format: uuid): sin cambios necesarios **Compilación:** BUILD SUCCESS Next: Phase 5 - Application Layer (ComposeContentService implementation)

T010: REST Controllers & DTOs (MockMvc tests: 8/8 PASS)
**REST Controller** (PlaybackController):
- GET /api/v1/playback/meditations
- Lists user meditations ordered by createdAt DESC
- Returns stateLabel (Spanish) + mediaUrls (nullable)
- GET /api/v1/playback/meditations/{id}
- Returns playback info for COMPLETED meditations
- Throws 404 if not found, 409 if not playable
**DTOs** (5 records):
- MeditationListResponseDto - meditation list wrapper
- MeditationItemDto - single meditation with state label
- PlaybackInfoResponseDto - playback info with media URLs
- MediaUrlsDto - audio/video/subtitles URLs (@JsonInclude NON_NULL)
- ErrorResponseDto - standardized error format
**DtoMapper** (@component):
- Domain Meditation DTOs translation
- ProcessingState Spanish labels:
- PENDING 'En cola'
- PROCESSING 'Generando'
- COMPLETED 'Completada'
- FAILED 'Fallida'
**Exception Handling**:
- PlaybackExceptionHandler (@RestControllerAdvice)
- MeditationNotFoundException 404 Not Found
- MeditationNotPlayableException 409 Conflict
- Uses Clock bean for timestamps
- PlaybackConfig: @bean Clock (systemUTC)
**Testing** (PlaybackControllerTest - 8/8 GREEN):
- MockMvc integration tests with @WebMvcTest
- Excludes GlobalExceptionHandler (catch-all conflicts)
- Tests: list meditations, playback info, 404/409 responses, state labels
- X-User-Id header authentication (temporary until US1 JWT)
**Technical Decisions**:
1. Temporary authentication: X-User-Id header instead of JWT (blocked by US1)
2. Excluded GlobalExceptionHandler in tests to avoid catch-all exception conflict
3. Removed basePackages from PlaybackExceptionHandler for test compatibility
4. @JsonInclude(NON_NULL) on mediaUrls/subtitlesUrl (optional fields)
**Test Results**:
- PlaybackControllerTest: 8/8 PASS
- All previous phases: Domain (53), Application (18), Infrastructure (14)
- Total unit tests: 93 GREEN
T011: React UI Components - Generated OpenAPI TypeScript client (typescript-fetch) - Components: StateLabel, MeditationCard, MeditationList, MeditationPlayer - Spanish labels + state-based styling - Accessibility: ARIA labels, semantic HTML - Play button disabled for non-COMPLETED meditations T012: State Management - React Query hooks: useMeditationList, usePlaybackInfo - Zustand store: playerStore (UI state) - Server-state (React Query) vs UI-state (Zustand) separation - Error handling: 404/409 responses with Spanish messages T013: Page & Routing - MeditationLibraryPage: Full integration - React Router v6: /library route + navigation - QueryClientProvider setup - Type-safe imports with vite-env.d.ts Build: SUCCESS (npm run build) Dependencies: react-router-dom@^6 added Tech Stack: - React 18, TypeScript 5.3 - TanStack React Query 5.17 - Zustand 4.4 - React Router 6 - Vite 5
