  "description": "LAYER 3 (CURRENT AUTHORITY / LIVE STATUS). The authoritative, live lifecycle state of a request. If live status cannot be obtained, the protocol MUST fail closed: report fail_closed=true and MUST NOT treat the request as authorized, settled, or executable. Invariant (Issue #96): when live=false, the schema MUST REJECT favorable/current-authority states that imply authorization, execution, or settlement — i.e. status MUST NOT be one of {authorized, awaiting_settlement, settled}. Only safe/non-favorable states (draft, failed, expired, revoked) are permitted when live=false. A schema that validates does not by itself prove on-chain or live state; it only proves the document is well-formed and fail-closed-correct.",
