Balcony Cue Light Afteruse Receipt Mechanic

The cue light is a state-pressure afteruse docket. It measures whether a narrow safety signal can be cited without becoming a universal clean permission slip.

Playable counters: cueLightProgress, usherBridgeTrust, lightCustodyDriftRisk, lightHeat, falseCleanLight, and futureRouteCost.

The future reader must consume the resulting state: named scope, named reader, usher bridge, reopened claimant, split safety/consent custody, quarantine, or recovery-only false default.
