### Publishing Order
Components will be published in dependency order:
1. **Level 0:** embeddenator-io, embeddenator-obs
2. **Level 1:** embeddenator-vsa
3. **Level 2:** embeddenator-retrieval
4. **Level 3:** embeddenator-fs

## 🔒 Security Posture
### Unsafe Code Inventory
**54 unsafe blocks across 6 files** require security audit:
| vsa | block_sparse.rs | ~20 | High |
| vsa | simd_ops_x86.rs | ~15 | High |
| fs | engram_file.rs | ~8 | Medium |
| fs | thread_pool.rs | ~5 | Medium |
| obs | timing.rs | ~4 | Low |
| obs | metrics.rs | ~2 | Low |
**Audit Status:** ⏹️ Planned for Phase 3 Week 1
### Security Requirements
For each unsafe block before publishing:
1. SAFETY comments present and comprehensive
2. Invariants documented and validated
3. Memory safety verified (no UAF, double-free, invalid pointers)
4. Soundness validated (no data races, UB)
5. Test coverage (unit, property, integration)
6. Miri and sanitizer checks passing

**Task:** Task 3.1 - Integration Testing
**Duration:** 2 days
**Deliverable:** Integration test suite + report
**Handoff Message:**
```
QA Tester, please begin Phase 3 integration testing:
1. Create tests/phase3_integration.rs
2. Test cross-component APIs (VSA→Retrieval→FS→Interop)
3. Test CLI integration with stubs
4. Test error recovery (RwLock poisoning, index corruption, SIMD fallbacks)
5. Run memory safety tests (miri, valgrind, asan)
6. Generate integration test report
All 7 components are ready at v0.2.0 in ~/Documents/projects/embeddenator/
Report back when testing complete or if issues found.
```
