## Project Alignment

### SCOPE Section Alignment
PROJECT.md already documents:
- "Australian CGT calculations with 50% discount for >12 month holdings" ✓
- "Portfolio tracking with mark-to-market valuation" ✓
- "User database for profiles, portfolios, settings" ✓

Trade model fully implements these requirements.

### ARCHITECTURE Section Alignment
PROJECT.md directory structure lists:
```
database/
  models/
    - user.py ✓
    - portfolio.py ✓
    - settings.py ✓
    - trade.py ✓ (NEW - Implemented)
```

### Phase 1 Database Completion
All 5 core database models now completed:
1. #2 Database setup (SQLAlchemy + PostgreSQL/SQLite)
2. #3 User model (profiles, tax jurisdiction)
3. #4 Portfolio model (LIVE, PAPER, BACKTEST types)
4. #5 Settings model (risk profiles, alerts)
5. #6 Trade model (CGT tracking)

Only #7 (Alembic migrations) remains pending.
