Merch Table Receipt Afteruse Mechanics

The receipt-afteruse mechanic is a state-pressure review: a later reader attempts to consume a merch receipt as clean authority. The review must expose the source receipt row, buyer/performer or explicit absence, booth/date context, cited scope, requested afteruse, harmed claimant, proof bridge, and future route effect.

Branches should alter at least three named counters or route flags so the replay can prove that the receipt was narrowed, bridged, split, quarantined, reopened, or falsely defaulted.
