## Verdict: PARTIAL COMPLIANCE

The NullNode implementation covers **core cryptographic primitives** (ML-KEM Braid, PIR, CBNP, secure memory) but lacks:

  1. **Hardware attestation infrastructure** (Part VI) - requires SEV/TDX-capable hosts
  2. **Full mobile optimizations** (Part II) - OS lifecycle integration missing
  3. **Group messaging** (Part I.3) - no scalable broadcast implementation
  4. **Advanced network features** (Part IV-V) - pipelining and jurisdictional enforcement

The codebase is suitable for **infrastructure/core nodes** but mobile-focused features require additional platform-specific development.
