Greenroom Proxy Badge Afteruse Receipt Mechanic / 候场室代理徽章后用回执机制

The mechanic stores proxy badge use as a scoped receipt. Required fields are the source badge row, delegated holder or explicit absence, original artist or witness, cited greenroom scope, requested afteruse, harmed claimant or explicit absence, proof bridge or explicit absence, selected badge posture, badge afteruse state after, future reader or route effect, and counter deltas.

Valid branches can certify a narrow interval, restrict the badge to the greenroom reader, attach the original person as proof bridge, reopen a harmed claimant queue, split badge access from custody authority, quarantine stale badge use, or default into a false clean badge scar. Every branch must mutate future readability rather than deleting the source row.

The mechanic rejects fixed turn triggers, dashboard-state triggers, and any universal clean access result.
