The before/after pair was listened to and the difference was barely detectable. That is a real result, not a bad test: sweeping the chain's overshoot shows the damage scales with it, and the pair happened to sit at the bottom of the range. chain peak 0.48x -> nothing clamped, -70 dB (16-bit rounding only) chain peak 1.35x -> 2.1% of samples, -25.1 dB <- what was listened to chain peak 2.69x -> 19.3% of samples, -9.1 dB chain peak 4.00x -> 48.8% of samples, -3.3 dB So a chain that stays under full scale is completely unaffected — the fix changes nothing for it — and 55f852a72's "audible distortion" framing is overstated for mild chains. The fix is still right: it destroys data the lane was about to scale down anyway. But it belongs with correctness work rather than with "renders sound wrong today", and the handoff now says so plainly so nobody re-derives the severity from the commit message alone. The commit itself is left alone rather than rebasing 15 commits over an adjective; the measurement lives here instead. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
