Orchestra Pit Credential Afteruse Receipt Mechanic
When a later route consumes an orchestra-pit credential, the game records the source credential row, holder or explicit absence, issuing authority or explicit absence, displaced musician/technician, requested afteruse, proof bridge, selected posture, after-state, future route effect, and named counter deltas.
Allowed postures are certify pit scope, restrict pit reader, attach musician witness bridge, split pit access, quarantine pit afteruse, or file a false-clean pit default that creates recovery-only future access.
