Deprecated alias of POST /v1/authority/grants/{grantId}/receipts: the same handler.

Records COMMITTED, FAILED, or INDETERMINATE. INDETERMINATE effects must be reconciled and are never safe for automatic retry. A COMMITTED claim proves an attempt was finalized, but an effect is confirmed only when digest-bound effect_evidence with status CONFIRMED is accepted. If the signed grant expires after a successful claim, finalization may continue only while the exact persisted claim token, nonce, correlation, and database claim lease remain valid. An expired unclaimed grant is never execution-eligible. A finalize request at or after the database-clock lease boundary fails closed and atomically records the claim as INDETERMINATE.

A verifying provider's signed effect receipt (Verifying Provider Profile, VP-3) may accompany the finalization as effect_receipt. It is verified against the organisation's registered provider keys and recorded in the commit evidence as presented, verified or not; it is never a reason to refuse the finalization. When the grant named the effect it expected and the verified receipt carries an effect digest, the receipt is also read as SIGNED_RECEIPT effect evidence, and confirms the effect only when the digests agree and the outcome is COMMITTED. An explicit effect_evidence takes precedence.
