Every track leaves a receipt. Every rights claim is in the envelope.
A music-gen merchant on the Visa CLI mints one hive-vcr-1 receipt per generated track. Source-corpus class, training rights posture, and likeness or voice-print attestation are co-signed before the audio returns.
The fields the operator co-signs before this call returns.
Every field below is co-signed by the operator with ML-DSA-65 and countersigned by Hive. Absence is not a default. Absence is a verification failure. The merchant cannot return the call's result without the receipt; the receipt cannot exist without these fields.

A generated track destined for a national broadcast carries the rights-class attestation in the same envelope as the audio hash. The buyer's compliance team verifies once, offline.
UGC platforms
Per-track receipts let a platform prove it knew, at generation time, whether the training corpus included a flagged artist. Knowledge is provable, not asserted.
Royalty distribution
Receipts feed a downstream royalty engine because the corpus_class field tells the engine which pool to credit. No reconciliation meeting.
One endpoint. One envelope. No Hive dependency in your inference path.
A music generation operator adopts hive-vcr-1 by appending the receipt envelope to the response and exposing a public verification key. Hive's countersignature is a sidecar; it does not sit on the critical path. If Hive disappears, the operator's receipts remain verifiable against the operator's own key.
