Understudy Consent Substitution Receipt Mechanics

A substitution receipt records the gap between performed by and licensed as. It is attached before a broadcast, sponsor, or archive route can spend an understudy performance as clean consent for the absent name-holder.

Required state fields:

• understudy_performer;
• borrowed_name_or_voice;
• consuming_route;
• requesting_authority;
• harmed_or_absent_rightsholder;
• proof_bridge_or_explicit_absence;
• selected_substitution_posture;
• consent_state_after;
• named counter deltas.

The unsafe default is false_clean_understudy_consent: the route continues, but later replay must show consent liability and recovery-only route pressure.
