● Committed (ca654af), Mac synced. Now the encryption audit — verify every stage is encrypted at rest (local + remote), including the audit. Let me
  check the encryption key source, whether stored logs/findings/artifacts are actually ciphertext, and the disk/space/remote layers:

  Ran 1 shell command 

● Encryption audit — strong across the board:
  - Local at-rest = 100%: FileVault (whole-disk) + app-level AES-256-GCM on the log/findings/artifact stores + AES-256 encrypted sparseimage per build
  space. Admin token 0600.
  - Remote: the vault→GCS copy is AES-256-GCM encrypted; artifacts are encrypted at rest and leave only over HTTPS.

  The one thing on FileVault-only (not app-level) is the gate's audit log — you flagged that explicitly. Let me wire app-level encryption for it.
  Checking the crypto tools on the Mac:

  Ran 1 shell command 

● age isn't there but OpenSSL is. I'll give the audit log app-level encryption on top of FileVault: encrypt each audit entry to a dedicated audit cert
  (private key in the vault → GCS, so it's encrypted local and remote, and only you can read the trail). First generate the audit keypair and store
  its private key in the vault:

  Ran 1 shell command 

● Audit key stored in the vault (encrypted + GCS-synced), local shredded. Now wire the gate to encrypt each audit entry to the audit cert:
