## 🔧 Technical Highlights

### Parallel Agent Execution

- 4 agents launched simultaneously in a single message
- Each agent worked in isolated worktree
- Zero merge conflicts (all independent implementations)
- Total concurrent execution time: ~agent execution time

### Code Quality

- All implementations passed pre-commit hooks
- Comprehensive test coverage (100% pass rate)
- Clean component boundaries (Polylith architecture)
- No breaking changes (all additive)

### Security Enhancements

- **Trust escalation prevention** (PR14)
- **Dependency attack mitigation** (PR15)
- **Audit trail for trust decisions** (PR17)
- **Observable ETL workflows** (PR16)

## 🔍 Review Recommendations

### Merge Order (Suggested)

**Option 1: Sequential** (safest)

1. PR #86 (Conformance tests)
2. PR #87 (Transitive trust)
3. PR #88 (Pack dependency validation) - integrates with PR14
4. PR #89 (ETL events) - independent
5. PR #90 (Promotion justification) - independent

**Option 2: Parallel** (fastest)

- Merge all 5 PRs in parallel (they are all independent)
- Resolve any minor conflicts if they arise

### Testing Strategy

- Each PR has comprehensive tests (100% passing)
- All PRs passed pre-commit validation
- Recommend running full test suite after merges
- Consider integration test across all 4 PRs

---

## 📝 Next Steps (Post-Merge)

### Immediate (OSS v1.0 Release)

1. ✅ Merge PR #86-90
2. Create OSS v1.0 release tag
3. Update documentation
4. Announce v1.0 release

### Near-Term (OSS v1.1)

**PR18-21** - ETL Important Features (~1,150 lines)

- PR18: Incremental ETL (~500 lines)
- PR19: ETL dry-run (~100 lines)
- PR20: Enhanced PI scanner (~300 lines)
- PR21: Trust-verified subchannel (~250 lines)

Can run all 4 in **parallel** using same agent approach.

### Future (OSS v1.x)

**PR10-13** - Enhancements (~1,550 lines)

## 🎓 Lessons Learned

### What Worked Well

1. **Parallel agent execution** - Massive time savings
2. **Worktree isolation** - Zero merge conflicts
3. **Clear spec references** - Agents understood requirements
4. **Comprehensive PR plan** - Detailed scope kept agents focused

### Optimizations for Next Phase

1. **Pre-validate dependencies** - Ensure all components exist before agent launch
2. **Shared test utilities** - Create common test helpers
3. **Integration tests** - Add cross-PR integration tests
4. **Documentation updates** - Keep docs in sync with implementations
