Both forms carry the registered adapter id; keys is owned and CLOSED by the adapter registration. linear/0.1 carries exactly the content key — every further secret is DERIVED from it (HKDF info rltp/v1/epoch-secret/<genesis digest>), never transported, so the log's contentKeyCommitment authenticates all consensus-relevant material.",
