Flytower Sandbag Knot Afteruse Receipt

A prior strip of flytower sandbag knot marked one hatch lane during a rehearsal evacuation. Later, a production caller tries to reuse that strip as clean authority for a different flyrail route, even though the old mark is not clean authority once the context changes after the handler, hatch map, and exposed crew position have changed.

The playable pressure is whether the player certifies current hatch authority, attaches a scoped afteruse receipt, splits original and later route readers, requires an editor checksum, publishes a crew notice, quarantines the claim, or lets a false-clean default mutate future route costs.
