Ticket Stub Reissue Liability

A ticket-stub reissue is a state-pressure mechanic. It opens only when a route, reader, or desk attempts to use a reissued seat/stub pair and the old holder, new claimant, reissue authority or explicit absence, displaced reader, and future reader are all visible.

Required surfaces:

• original stub row;
• old holder and new claimant;
• reissue authority or explicit absence;
• displaced reader;
• selected liability posture;
• future route/readback effect;
• counter movement for at least three pressure surfaces.

Forbidden shortcuts:

• fixed turn or calendar-only trigger;
• raw ticket count;
• generic refund total;
• dashboard or lens-health state;
• universal clean replacement flag.

The mechanic creates a durable liability posture before the reissued copy can be spent as proof.
