## Recommended Implementation Order

Based on dependencies and value delivery:

1. **SPRINT_5100_0003_0001** (SBOM Interop) - No blockers, high value for ecosystem compatibility
2. **SPRINT_5100_0003_0002** (No-Egress) - Parallel with above, proves air-gap capability
3. **SPRINT_5100_0006_0001** (Audit Packs) - Dependencies met, critical for compliance
4. **SPRINT_5100_0004_0001** (Unknowns Budgets) - Depends on Sprint 4100 completion
5. **SPRINT_5100_0005_0001** (Router Chaos) - Independent, can run in parallel

## Success Metrics

- [ ] Phase 2: 95%+ SBOM interop parity, air-gap tests pass with no network
- [ ] Phase 3: CI gates block on budget violations, PR comments working
- [ ] Phase 4: Router handles 50x load spikes with <30s recovery
- [ ] Phase 5: Audit packs import/export with replay producing identical verdicts
