Architectural Correction: - Removed GenerationRequest and GenerationResult from domain models - These are DTOs (Data Transfer Objects), not domain Value Objects - Request/Result objects belong in Application layer (app/dto/), not Domain - Domain should only contain pure business concepts (VoiceProfile, AudioSample) Rationale: - Domain layer must be independent of application use cases - 'Request' and 'Result' imply application operations, not business concepts - GenerationRequestDTO and GenerationResultDTO already exist in Phase 4.1 - This maintains proper hexagonal architecture boundaries Updated task 2.1: - VoiceProfile: Entity with identity and behavior ✓ - AudioSample: Immutable Value Object ✓ - Added note explaining domain vs application distinction - Enhanced VoiceProfile with total_duration property and remove_sample() method - Enhanced AudioSample with validation methods This ensures clean separation between domain (business logic) and application (use cases).

- Create TTSEngine port - get_supported_modes() for mode discovery - generate_audio() for speech synthesis - validate_profile() for profile validation - Create AudioProcessor port - validate_sample() for audio validation - process_sample() for metadata extraction - normalize_audio() for loudness normalization - Create ProfileRepository port - save() for persistence - find_by_id() for retrieval - list_all() for listing - delete() for removal - Create ConfigProvider port - get() for config retrieval - get_all() for full config - reload() for dynamic updates - All ports follow Dependency Inversion Principle - Infrastructure will implement these interfaces - Task 2.2 complete
- Add .kiro/ to .gitignore - Remove .kiro files from git tracking - Kiro specs and steering files are local workspace files
- Create VoiceCloningService - create_profile_from_samples() with validation - validate_profile_for_cloning() for quality checks - Orchestrates AudioProcessor port - Applies business rules (2+ samples, 20s+ duration) - Create AudioGenerationService - generate_with_profile() with validation - chunk_text_for_generation() for optimal chunks - Orchestrates TTSEngine port - Validates mode support and profile compatibility - Pure business logic, depends only on ports - Task 2.3 complete

All validation criteria met: - Use cases orchestrate domain and infrastructure correctly - All 133 tests passing (including 44 new application tests) - Use cases work with mocked adapters - DTOs serialize/deserialize correctly
- Renamed tests/application/ → tests/app/ to match src/app/ - Renamed tests/infrastructure/ → tests/infra/ to match src/infra/ - Removed __init__.py files from test directories (pytest best practice) - Updated conftest.py to ensure src/ is prioritized in sys.path - Updated tasks.md to reflect final test directory structure - All 133 tests passing The key insight: test directories should NOT have __init__.py files unless specifically needed for fixtures. Having __init__.py makes pytest treat them as packages and add them to sys.path, causing naming conflicts with source directories.
- Create api layer with TTSStudio class as main entry point - Implement dependency injection for all adapters and use cases - Add methods: create_voice_profile, generate_audio, list_voice_profiles, delete_voice_profile, validate_samples - All methods return dict with status/error for easy JSON serialization - Fix ValidationSummary iteration in validate_samples method - Comprehensive logging throughout - All 133 tests passing - Completes task 5.1

- Exclude downloaded Qwen3-TTS models (~3.4GB) - Exclude generated outputs and cache files - Prevents committing large model files to repository
- Models NOT included in installer (downloaded on-demand by user) - Models stored in OS-specific user directories, not in source code - Installer size: ~50-100MB (without models) - User downloads Qwen3-TTS (~3.4GB) from UI on first launch - User can delete models to free space and re-download anytime - Development: models in apps/core/data/ (gitignored) - Production: models in ~/Library/Application Support/TTS Studio/models/ (macOS) This ensures: - Small installer size - User control over disk space - Models can be updated independently - Multiple models supported in future
