Oxygen Mask Choir Sedation Default / 氧气面罩合唱组镇静默认

This guarded event resolves only after Ward 05 arms the sedation miss. It records the exact source flag storyteller_mask_choir_sedated, removes card-storyteller-oxygen-mask-choir, reduces voice integrity, raises audience witness debt, fan oxygen pressure, medical harm debt, and future route cost, then leaves recovery-only play.

The event cannot turn a medical scar into testimony consent or silently restore the choir.
