Standby Call Slip Afteruse Receipt Mechanics

A standby call slip is route evidence, not a blank casting warrant. The game must preserve:

• source call slip row;
• summoned standby or explicit absence;
• role and show scope;
• requested afteruse;
• future reader or route;
• harmed performer or explicit absence;
• proof bridge or explicit absence;
• selected slip posture;
• after-state, future reader effect, and named counter deltas.

The safe branches create costs as well as relief: stage-manager proof adds inspection heat, harmed-performer reopening raises queue pressure, and splitting call evidence from casting authority slows sponsor routes. The default records a false-clean standby claim and makes future play recovery-only.
