Lighting Booth Key Afteruse Receipt

A borrowed lighting booth key survives a night-of-show access handoff. Later, a sponsor editor and route asset reader try to spend that key as proof of clean booth access, consent to edit blackout evidence, or custody over the light cue archive.

The key is evidence of a named access interval, not universal authority. Any future route that consumes it must preserve the source key number, booth holder or explicit absence, access window, cited lighting scope, requested afteruse, harmed technician, proof bridge, selected posture, after-state, and future route effect in replay.
