SCOPE & ARCHITECTURE ALIGNMENT
==============================

SCOPE Section (No updates needed):
PROJECT.md already covers:
- "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 implementation fully aligns with documented SCOPE.

ARCHITECTURE Section (No updates needed):
PROJECT.md directory structure already lists trade.py:
  database/
    models/
      - user.py (implemented)
      - portfolio.py (implemented)
      - settings.py (implemented)
      - trade.py (implemented - NEW)

Trade model fully implements portfolio layer as documented.
