SHA-256 Merkle Cryptographic Release Lock

Binds CAD geometry, FEA stress proofs, WPS welding schedules, and NDT inspection logs into a tamper-proof digital certificate.

AS9100 & ISO 9001 Cryptographic Traceability

When an engineering package is certified, ZylForge computes a SHA-256 Merkle root hash (`release_manager.py`). Any post-release modification to part dimensions, materials, or weld quality instantly breaks the Merkle tree hash, guaranteeing complete audit integrity for aerospace, defense, and oilfield clients.
