**Status:** IN PROGRESS  
**Started:** 2025-11-21  
**Approach:** Full TDD (Test-Driven Development)

## Implementation Progress

### ✅ Completed

**Infrastructure:**
- [x] Test framework setup (pytest, conftest.py, factories)
- [x] Test design document (37 test cases mapped)
- [x] SQLAlchemy models (Project, Item, Link, Event, Agent)
- [x] Base CLI framework (Typer app, version command)
- [x] Directory structure (src/tracertm/, tests/)

**Models Created:**
- [x] `src/tracertm/models/base.py` - Base model + TimestampMixin
- [x] `src/tracertm/models/project.py` - Project model
- [x] `src/tracertm/models/item.py` - Item model with optimistic locking
- [x] `src/tracertm/models/link.py` - Link model
- [x] `src/tracertm/models/event.py` - Event model (event sourcing)
- [x] `src/tracertm/models/agent.py` - Agent model

**CLI Framework:**
- [x] `src/tracertm/cli/app.py` - Main Typer app
- [x] `src/tracertm/cli/commands/config.py` - Config commands (init, show, set)

### 🚧 In Progress

## Time Estimate

**Completed:** ~3 hours (infrastructure + models + CLI framework)  
**Remaining:** ~17-20 hours

**Breakdown:**
- Story 1.2 (Database): 4-5 hours (migrations, connection pooling, health checks)
- Story 1.3 (Projects): 3-4 hours (repositories, services, CLI commands)
- Story 1.4 (Config): 2-3 hours (Pydantic schemas, config hierarchy)
- Story 1.5 (Backup): 3-4 hours (JSON export/import, validation, compression)
- Story 1.6 (Errors): 2-3 hours (exception hierarchy, error messages, fuzzy matching)
- Test Designs Epic 2-8: 3-4 hours (7 documents)
- Traceability Matrix: 1-2 hours (automated generation)

**Total Estimated Time:** 20-23 hours remaining

---

## Next Immediate Steps

1. **Create database connection module** (Story 1.2)
2. **Setup Alembic migrations**
3. **Write integration tests for database**
4. **Implement config manager** (Story 1.4)
5. **Write unit tests for config**
6. **Continue with remaining stories**
