## Documentation Standards Compliance
- Format: Follows Keep a Changelog conventions
- Cross-references: File paths with line:ranges (e.g., `[file:spektiv/api/models/trade.py:86-137]`)
- Test documentation: Includes file locations with test counts and line counts
- Migration documentation: References migration file with version number (005)
- Absolute paths: All paths use absolute form starting from project root
## Scope & Architecture Alignment
### SCOPE Section
PROJECT.md already includes:
- "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 directly supports all these in-scope requirements.
### ARCHITECTURE Section
PROJECT.md directory structure already lists:
```
database/
models/
trade.py (✓ Implemented)
```
Trade model fully implements the portfolio layer as documented.
## Summary of Changes
Documentation successfully updated for Issue #6 implementation:
1. **CHANGELOG.md**: 34-line entry with 14 feature points and proper file:line references
2. **PROJECT.md**: Issue tracking updated to reflect 5 completed database issues
3. **Validation**: All file paths, line numbers, and test counts verified
4. **Standards**: Follow Keep a Changelog conventions with proper cross-referencing
No additional documentation was needed because:
- SCOPE section already covers CGT requirements
- ARCHITECTURE section already lists trade.py
- API documentation will be auto-generated from docstrings
- Test documentation integrated into CHANGELOG with full coverage details
