h04 ranking delta handoff

Exact log entry

Recommendation

No tier or score move: keep tier B, mech 3 / deliv 2 / misha_fit 2.

The audit invalidates only the downstream dB/audiogram transformation. It neither falsifies h04’s upstream mechanism nor changes the already binding OHC-LNP delivery limitation, so demotion would treat missing outcome calibration as negative biological evidence. Promotion is also impossible. Keep the existing next step; mark the dB outcome chain quarantined and change the literature-audit status from fixed to partial.
