Stage Manager Headset Afteruse Mechanics

A headset row is not universal consent. The mechanic requires the future route to expose the source headset row, stage manager or explicit absence, booth/channel/date context, cited call scope, requested afteruse, harmed claimant or explicit absence, proof bridge or explicit absence, selected posture, afteruse state, future reader effect, and counter deltas.

Valid outcomes include named-scope certification, named-reader restriction, stage-manager bridge attachment, harmed-claimant reopening, call/consent split, quarantine, and a false clean default that mutates future play.
