Greenroom Badge Afteruse Receipt Mechanics

The mechanic treats backstage badges as scoped route assets. A badge row must name who held it, who issued it, who is displaced or explicitly absent, what proof bridges the later use, and which future reader consumes the state.

Valid branches may certify the original scope, restrict the badge to a named reader, attach a greenroom witness bridge, split access between route readers, quarantine the badge afteruse, or accept a false-clean default that scars future play.
