Green Room Tea Urn Tag Afteruse Receipt Mechanics
This mechanic is local authority only: a source green room tea urn tag can prove its original served batch, but it cannot become universal hospitality, 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 urn tag id, urn inventory or visible absence, original service span, original batch sheet version, original steward, requested afteruse service, afteruse caller, current batch sheet version or absence, current steward or absence, displaced guest or allergy witness, proof bridge or explicit absence, selected posture, and future route effect.
Seven review branches must be present: certify current steward, attach the green room tea urn tag afteruse receipt, split original and later green room readers, require editor checksum, publish allergy witness notice, quarantine urn tag afteruse claim, and false-clean urn default. The default follow-up must leave exactly one durable terminal state and exactly one matching future route effect.
