Orchestra Mute Clip Afteruse Receipt / 乐池弱音夹后用回执

Supports Orchestra Mute Clip Afteruse Receipt Lens. The design keeps one pit-desk mute clip scoped to one cue row so later recap, archive, sponsor, and route-asset readers cannot spend it as clean performer consent, global sound authority, or voice custody.

Required play surface: source row, brass player or explicit absence, pit mix context, cited mute scope, requested afteruse, harmed claimant or explicit absence, proof bridge, future reader effect, relief/cost branch, and false-clean default.
