Callboard Pin Hole Afteruse Receipt

A removed callboard notice leaves pin holes that prove one notice was posted. Sponsors and archive staff try to reuse the holes as if every performer had been served, but the route must preserve the missing notice, remover, claimant, and future reader before the holes can matter.

The playable pressure is narrow: certify the original notice scope, restrict the future reader, attach the stage-manager bridge, reopen a missed understudy claimant, split notice from service, quarantine afteruse, or accept a false-clean default that makes later route recovery more expensive.
