Orchestra Stand-Light Bulb Afteruse Receipt Mechanic

The mechanic opens from state pressure: a future route tries to cite an old stand-light bulb receipt after the stand, dimmer, or electrician chain has changed. It is not triggered by turn count, raw bulb count, dashboard health, or lens status.

Required visible facts are source bulb, musician or explicit absence, stand position or explicit absence, electrical lead or explicit absence, requested afteruse, future reader, changed circuit/custody or explicit absence, proof bridge, harmed musician or crew member, selected posture, after-state, future-route effect, and counter deltas.
