- **MCP Server**: 10/10 FRs implemented (100%) — 50+ tools, streaming, metrics all working

### Critical Path Dependencies

1. **Phase 0 (Foundation)** ✅ PASSED
   - Infrastructure (auth, DB, caching, NATS) → FR-INFRA-001..007, 009-010
   - All services healthy; health checks active

2. **Phase 1 (Discovery)** → FR-DISC-001..010 ✅ COMPLETE
   - GitHub/Jira imports; spec parsing; auto-linking
   - Ready for Phase 2

3. **Phase 2 (Qualification)** → FR-QUAL-001..010 🟡 NEAR
   - 8/10 complete; impact analysis and shortest-path need optimization
   - Blocking: graph query latency (target <500ms p95)

4. **Phase 3 (Application)** → FR-APP-001..010 ✅ COMPLETE
   - Full CRUD, links, workflows, search operational

5. **Phase 4 (Verification)** → FR-VERIF-001..010 🟡 PARTIAL
   - BDD, test execution, coverage tracking done
   - Blocking: compliance verification (digital signatures), verification matrix

6. **Phase 5 (Reporting)** → FR-RPT-001..010 🟡 NEAR
   - Dashboards, exports done; report scheduling 72%
   - Blocking: scheduling infrastructure (Temporal workflows)

7. **Phase 6 (Collaboration)** → FR-COLLAB-001..010 🟡 PARTIAL
   - Real-time, webhooks, SSO done
   - Blocking: bidirectional GitHub sync, Linear integration

8. **Phase 7 (AI & Automation)** → FR-AI-001..010 + FR-MCP-001..010 🟡 PARTIAL
   - MCP 100% complete; agents 50% (coordination done, generation deferred)
   - Blocking: requirement generation, documentation generation

### Performance Targets vs. Reality

| Target | Goal | Current | Gap | Priority |
|--------|------|---------|-----|----------|
| Query latency | <100ms p95 | ~150ms | +50ms | High |
| Graph (10K nodes) | <500ms p95 | ~700ms | +200ms | High |
| Bulk import | 1K items/min | 1.2K items/min | ✅ -200/min | Done |
| WebSocket latency | <100ms | ~80ms avg | ✅ Achieved | Done |
| Test coverage | 90% | ~50% | -40% | Critical |
| Uptime SLA | 99.5% | 99.6% (infra) | ✅ Achieved | Done |

### Risk Assessment

**High Risk:**
- Test coverage (50% vs 90% target) — Gap of 40 points; blocks Phase 8 (docs/onboarding)
- Onboarding time (4-6h vs 30min target) — Requires quick-start guide + Docker Compose
- Graph query performance (700ms vs 500ms target) — Needs query optimization + caching tuning

**Medium Risk:**
- Impact analysis completion (PARTIAL) — 80% done; optimization needed
- Compliance verification (PARTIAL) — Digital signature workflow pending Temporal integration
- Report scheduling (72%) — Temporal workflow dependency

**Low Risk:**
- All Phase 0-3 FRs complete and stable
- MCP server fully operational (100% coverage)
- Infrastructure solid (99.6% uptime, all health checks passing)

### Next Actions (Priority Order)

1. **Immediate** (Phase 2.1): Optimize graph queries for 500ms p95 target
   - Profile Tarjan/BFS; add query plan cache; Neo4j indexing

2. **Urgent** (Phase 2.2): Increase test coverage from 50% → 70%+
   - Add integration tests for QUAL services (impact, shortest-path)
   - Add E2E tests for workflows (status, bulk operations)

3. **Important** (Phase 3.1): Complete bidirectional GitHub sync
   - Implement export/push workflow for GitHub integration

4. **Important** (Phase 3.1): Complete compliance verification
   - Integrate digital signature workflow via Temporal

5. **Nice-to-have** (Phase 3.2): Requirement generation + Auto-documentation
   - AI generation with human-in-loop review
