### Requirements Added (Phase 7)

| ID | Description | Effort |
|----|-------------|--------|
| REQ-GO-048 | ASCII tables matching tabulate | 1.5w |
| REQ-GO-049 | Phase names from config | 0.5w |
| REQ-GO-050 | Status -v category list format | 1.0w |

### Medium Priority (Full parity)

1. **Phase 9 commands** - reconcile, diff, config, makefile, docs
2. **Phase 10 commands** - setup, bootstrap, sync, install, analyze
3. **REQ-GO-032: Jira adapter** - Enterprise integration

### Lower Priority (Nice to have)

1. **Phase 12 dashboards** - serve, tui, mcp-server
2. **REQ-GO-034: Markers** - Language-agnostic discovery

## Test Coverage

### Go CLI Tests

| Package | Tests | Coverage |
|---------|-------|----------|
| internal/cmd | 15+ | ~80% |
| internal/database | 10+ | ~85% |
| internal/config | 5+ | ~75% |
| internal/graph | 12+ | ~90% |
| internal/adapters | 7 | ~70% |
| test/parity | 4 | System |

### Missing Test Categories

1. Integration tests with real GitHub/Jira APIs
2. Cross-platform binary tests
3. Performance benchmarks
4. Fuzz testing for CSV parsing

## Conclusion

The Go CLI port has successfully implemented the **core functionality** needed for basic RTM operations. All essential read/write commands work and produce output matching the Python CLI.

**Key achievements:**
- Single static binary (no CGO)
- Cross-platform builds
- Feature parity for core commands
- GitHub adapter working

**Key gaps:**
- Distribution infrastructure (GoReleaser, Homebrew)
- Advanced collaboration features
- Zero-trust security integration
- Dashboard interfaces

**Recommended next steps:**
1. Complete Phase 14 (Distribution) - unblocks v1.0 release
2. Add deprecation warnings to Python CLI
3. Beta test with early adopters
4. Complete Phase 9-10 for full command parity
