**Documentation Updated**:
- `docs/implplan/SPRINT_5100_0000_0000_epic_summary.md` - Master epic summary
- `docs/19_TEST_SUITE_OVERVIEW.md` - Test suite documentation
- `tests/AGENTS.md` - AI agent guidance for tests directory

### Key Concepts Implemented

1. **Deterministic Replay**: Run Manifests capture all inputs for byte-identical verdict reproduction
2. **Canonical JSON**: RFC 8785 principles for stable serialization
3. **Evidence Index**: Linking verdicts to complete evidence chain
4. **Air-Gap Compliance**: Network-isolated testing with `--network none`
5. **SBOM Interoperability**: Round-trip testing with Syft, Grype, cosign
6. **Unknowns Budget Gates**: Environment-based budget enforcement
7. **Router Backpressure**: HTTP 429/503 with Retry-After validation
8. **Audit Packs**: Sealed export/import for compliance verification

### Release Blocking Gates

- Replay Verification: 0 byte diff
- Interop Suite: 95%+ findings parity
- Offline E2E: All pass with no network
- Unknowns Budget: Within configured limits
- Router Retry-After: 100% compliance
