### Development Methodology

- **Spec-Driven Development (SDD):** Requisiti definiti prima dell'implementazione
- **Test Driven Development (TDD):** Red-Green-Refactor cycle
- **Conventional Commits:** Standardizzazione messaggi commit
- **Common Changelog:** Gestione versioni e cambiamenti

### Changed

- **Codebase reorganization:**
  - Removed `export/` directory (workspace temporaneo per spec-driven)
  - Removed `scripts/` directory (vuota)
  - Moved templates from `docs/` to `.opencode/templates/`
  - Updated `.gitignore` to exclude workspace directories

### Added

- **Core API implementation:**
  - `api/main.py` - FastAPI application entry point
  - `api/dependencies.py` - Dependency injection (API key auth, settings)
  - `api/routes/health.py` - Health check endpoints (/health, /ready, /live)
  - `core/logging.py` - Structured logging configuration with structlog

- **Templates for OpenCode agents** (`.opencode/templates/`):
  - `architecture-adr.md` - Architecture Decision Records template
  - `bug-ledger-entry.md` - Bug documentation template
  - `progress-tracking.md` - Task progress tracking template
  - `githistory-entry.md` - Git commit context template

- **Test suite expansion:**
  - `tests/unit/test_api/test_main.py` - API main module tests
  - `tests/unit/test_api/test_health.py` - Health endpoints tests
  - `tests/unit/test_core/test_logging.py` - Logging configuration tests

## [0.2.0] - 2026-04-06

### Sprint 1: Notebook Management CRUD

#### Added

- **Notebook CRUD Endpoints:**
  - `POST /api/v1/notebooks` - Create new notebook with title and description
  - `GET /api/v1/notebooks` - List notebooks with pagination, sorting, and ordering
  - `GET /api/v1/notebooks/{id}` - Get notebook by UUID
  - `PATCH /api/v1/notebooks/{id}` - Partial update (title and/or description)
  - `DELETE /api/v1/notebooks/{id}` - Delete notebook (returns 204 No Content)

- **Core Services:**
  - `NotebookService` - Business logic for notebook operations
  - Integration with `notebooklm-py` client
  - Lazy client initialization with error handling
  - Title validation (3-100 characters)

- **API Models:**
  - `NotebookCreate` - Request model for notebook creation
  - `NotebookUpdate` - Request model for partial updates
  - `NotebookListParams` - Query parameters for listing
  - `Notebook` / `PaginatedNotebooks` - Response models
  - `ApiResponse[T]` - Standard response wrapper
  - `ResponseMeta` - Metadata (timestamp, request_id)

- **Error Handling:**
  - `ValidationError` - Input validation errors (400)
  - `NotFoundError` - Resource not found (404)
  - `NotebookLMError` - External API errors (502)
  - Standardized error response format

- **Comprehensive Test Suite:**
  - 31 unit tests for NotebookService (97% coverage)
  - 26 integration tests for API endpoints
  - Test categories: create, list, get, update, delete
  - Error case coverage: validation, not found, API errors

#### Changed

- Fixed router prefix duplication (removed `/notebooks` from router)
- Fixed JSON serialization in error responses (ResponseMeta as dict)
- Updated API route handlers with proper error handling
