Pit Orchestra Tuning Note Afteruse Mechanics

The tuning note is a narrow evidence surface, not universal consent. It carries source_tuning_note_row, player_musician_or_absence, rehearsal_cue_context, cited_tuning_scope, requested_afteruse, future_reader_or_route, harmed_claimant_or_absence, proof_bridge_or_explicit_absence, tuning_afteruse_state_after, future_reader_or_route_effect, and named counter deltas.

The review is state-pressure driven and explicitly rejects fixed turn/day triggers, raw note counts, dashboard health, or unstated future readers.
