Assistive Listening Receiver Afteruse Receipt Mechanics
This mechanic is local authority only: a source assistive listening receiver can prove its original served batch, but it cannot become universal accessibility, fan-oxygen, or artist-safety authority after the service route changes.
The afteruse review requires seven local evidence cards, one state-pressure rite, and a false-clean default event. Required evidence fields: source receiver tag id, receiver inventory or visible absence, original service span, original checkout sheet version, original access liaison, requested afteruse service, afteruse caller, current checkout sheet version or absence, current access liaison or absence, displaced guest or caption liaison witness, proof bridge or explicit absence, selected posture, and future route effect.
Seven review branches must be present: certify current access liaison, attach the assistive listening receiver afteruse receipt, split original and later balcony access desk readers, require editor checksum, publish caption liaison witness notice, quarantine receiver tag afteruse claim, and false-clean receiver default. The default follow-up must leave exactly one durable terminal state and exactly one matching future route effect.
