Hardware HMAC Signing

Binding workstation CPU and motherboard serial fingerprints for non-repudiable decision verification.

AnchorGit derives a non-invertible SHA-256 HMAC signature from your workstation CPU serial and motherboard GUID. This cryptographic proof ensures that decisions cannot be post-dated or spoofed by third-party tools.
