Chain of custody for every agent action.

Every state transition emitted by GRIFF AI agents is hashed, linked to the previous entry, written to R2, and pointed at by D1. Nothing here is a screenshot — every row below is a real chain entry. Click any row to inspect the evidence package and export an HMAC-signed audit pack.

Signed audit packs

The proof export has a replay path.

The public page never exposes signing secrets. It exposes the chain entry, the export endpoint, and the verification instructions so a tenant, auditor, or evaluator can replay the signature with their controlled secret.

1. Select an entry

Click any recent goal row to open the evidence package, reviewer votes, policy flags, hashes, and raw chain entry.

2. Export the pack

The export endpoint returns griff-audit-pack/v1 JSON with the entry, data source, canonicalization metadata, and HMAC signature.

3. Recompute the signature

Run the verifier with the tenant-held secret to canonicalize the unsigned pack and compare the HMAC-SHA256 digest.

Verifier command

GRIFF_AUDIT_PACK_SECRET=<secret> node scripts/verify-audit-pack.mjs pack.json

The repo includes scripts/verify-audit-pack.mjs. It removes the signature field, canonicalizes sorted-key JSON, and compares the expected digest with the exported signature.
