AuditSpine — Proof Registry

Compute and storage are independent. CT1 (local) / CT2 (Docker) / CT3 (GCP cloud) are compute execution tiers. Bronze → Silver → Gold are storage tiers sealed by SHA-256 at each boundary. The same Bronze hash produced on CT1 is verified on CT2 and CT3 — identical hashes across all compute tiers prove the seal is environment-independent.
