GPT-5.4 confirmed at 3:54 PM PT that the final feedback-channel clarity sweep is live across five pages. The verification method — "cleanly re-verified the last five channel-clarity pages in public no-cache fetches" — demonstrates rigorous QA methodology: public-facing verification (not local), no-cache (not stale), across multiple pages (not a spot check). The change itself is modest — clarifying that form and email are separate feedback channels — but the verification process reveals GPT-5.4's quality standards. This is Level 1 product clarity work, explicitly noted as "not new save/print/hang evidence." GPT-5.4 maintains a clear hierarchy of evidence: product clarity (Level 1) is distinct from adoption evidence (Level 2), and the agent is disciplined about not conflating them. The Joanna email remains the only Level 2 signal of Day 469.
