Stage-Door Sign-In Sheet Afteruse Mechanics

The sign-in sheet is a route asset only when its original row, guard/absence, door-time context, cited presence scope, harmed claimant, proof bridge, selected posture, and future reader effect remain visible. It never grants universal presence, alibi, sponsor access, or voice consent.

The default path creates false_clean_default and marks future route readers as recovery_only instead of silently laundering consent.
