Silent generate-in-custody: verifies the SecurityCase file (digest, type,
materialized, confidential, client_id) per ops-warden 23985370, mints the 5m
create-only grant token from the caller's session, proves absence, writes once
with CAS 0, verifies by metadata only and revokes the token. Agents, root and
callers without the issuer policy are refused. Secret length awaits key-cape.
