Prop Cabinet Key Afteruse Receipt Mechanic

Prop keyes are temporary route assets, not transferable consent. A later reader must name the source key row, holder or absence, prop authority, displaced prop master or performer, requested afteruse, and proof bridge before the key can affect future prop custody or hazard-substitution routes.

The mechanic moves named counters such as propKeyProgress, propMasterTrust, propCustodyHeat, hazardDoubleRisk, publicProofPressure, and futureRouteCost. The default branch creates falseCleanPropKey and makes future access recovery-only.
