Booth Monitor Hiss Afteruse Receipt Mechanics

Use the hot-mic escrow review surface for this slice. The receipt row must name the source hiss, original booth listener or explicit absence, captured speaker or explicit absence, claimed future use, harmed performer/audience, proof bridge or explicit absence, selected branch, counter deltas, and future reader effect. Any false-clean branch must mutate durable state as recovery-only evidence rather than a reusable permission token.
