ST-SCALE-05 Balcony Audio Custody / 二层看台音频保全

This source rite performs first custody only. It requires the actual balcony witness phone and an actual audit, fan archive, or black-box custody credential.

• public_copy creates storyteller.card.balcony_witness_phone_public_derivative.v1, raises public accountability, and lowers witness safety.
• sealed_copy creates storyteller.card.balcony_witness_phone_sealed_master.v1, lowers audit heat, and raises fan radicalization.

Both branches preserve the 37-second source window and mark first custody resolved. Neither branch authorizes a later reader to infer more than the source supports. That later inference is governed by Balcony Witness Phone Afteruse Review.
