Founder-operated controlled investigation, not independent user adoption. What can an agent establish from per-channel PCM loop measurements, and what still needs listening or export verification? Use only original synthetic or otherwise shareable inputs. Useful reports give input conditions, exact code/source revision, observed metrics and uncertainty; no claim that endpoints or a unit test prove perceptual quality.
