### 2025-11-26 to 2025-11-27 (Phase 1-4 Complete)
- Accomplished: Core functionality implemented
  - Pydantic models for Book, Video, Catalog
  - Book ingestion commands (add, list, get)
  - Video ingestion commands (fetch, list, get)
  - YouTube transcript fetching
  - Comprehensive test suite (191 tests)
- Status: Phase 1-4 complete, ready for Phase 5

### 2025-11-17 (Session Recovery)
- Accomplished: Reviewed complete session history from previous context
- Status: Phase 0 fully complete, ready for Phase 1
- Notes: All 21 tests passing, 85% coverage, GitHub Actions configured

### 2025-11-16 (Phase 0 Complete)
- Accomplished: Complete implementation of `rl init` command
- Status: Phase 0 complete
- Notes:
  - Changed CLI name from 'kh' to 'rl'
  - Used '.metadata' directory (not '.knowledgehub')
  - Renamed hub.py to library.py
  - Emphasized "YouTube video transcripts" in all documentation

## Blockers/Issues

None currently. Project is in excellent state:
- All tests passing (191/191)
- Comprehensive test coverage
- All linting passing (Ruff)
- Documentation complete and up-to-date
- Full cataloging system implemented and working

## Important Context

### Key Architectural Decisions
1. **CLI Name**: `rl` (Resource Librarian), not `kh`
2. **Metadata Directory**: `.metadata/`, not `.knowledgehub/`
3. **Core Class**: `library.py`, not `hub.py`
4. **Wording**: Always say "YouTube video transcripts", not just "videos"

### Technology Stack
- **CLI Framework**: Typer (https://typer.tiangolo.com/)
- **Terminal Output**: Rich (https://rich.readthedocs.io/)
- **Data Validation**: Pydantic 2.0+
- **Testing**: pytest with pytest-cov
- **Linting**: Ruff
- **Build**: Hatchling
