Flytower Sandbag Knot Afteruse Receipt Mechanic

A floor-knot receipt is local authority only. It can prove the original knot, hatch lane, handler, route-map version, caller, and exposed crew conflict, but it cannot grant universal flyrail-route authority or a clean public recap.

Required evidence fields: original knot, hatch lane, handler, route-map version, caller, and exposed crew conflict.

The runtime evidence must show seven review branches and a false-clean default event that clears pending flags while leaving exactly one durable terminal state and one future route effect.
