Cloakroom Claim Tag Afteruse Receipt Mechanics

The cloakroom claim tag mechanic treats a checked-item ticket as scoped evidence rather than universal identity authority. A review opens only when a future reader tries to consume the tag after peg, clerk, or holder context has become contested.

Required state pressure includes source claim tag, peg marker or explicit absence, clerk shift or changeover, disputed holder or explicit absence, requested afteruse, future reader/route, selected posture, after-state, counter deltas, and future route effect.

Branches must expose relief and cost: certify claim scope, bind clerk shift, reopen the missing holder, split storage from identity custody, quarantine the tag, or record a false clean default.
