Reference Fingerprints

Every champion master, measured and sha256-provenanced. A counsel- and partner-auditable surface: what was recorded, at what sample rate, with what effective bandwidth, and the attack-transient reference. Attack values are references, never pass/fail thresholds. Contracted audio is never served here — this is derived metadata only.

Take-to-take variance — the tolerance-honesty table (#15)

The same champion, the same call, across takes. This is why attack is a reference and never a pass/fail bar — a tolerance would have to contain the champion's own spread first.
