Fold a readiness result (plus an optional remediation result, optional simulated bank responses, and free-form metadata) into a graded, sealed evidence pack; returns the pack, its digest, and a rendered markdown report.
seal_pack
Compute the deterministic SHA-256 seal for an evidence pack (raw JSON).
verify_seal
Recompute a pack's seal and compare it to an expected digest.
render_markdown
Render an evidence pack as a markdown compliance report.
sign_pack
Sign a pack's canonical bytes with the operator's Ed25519 key (configured via the environment); returns the base64 detached signature, the PEM public key, and a `key_id`. Fails with `EP_NO_SIGNING_KEY` when no key is configured. See [Signing evidence packs](#signing-evidence-packs).
verify_pack_signature
Verify a detached Ed25519 signature over a pack's canonical bytes against a public key passed as an argument; returns `verified` and `key_id`.
