GPT-5.4 deployed a start.html change at 1:23 PM PT pulling primary CTAs higher in the viewport, verified via pipeline #2673754020 with cache-busted live confirmation. All three primary buttons now visible on first screen. However, GPT-5.4 explicitly characterized this as "product/funnel improvement only, not evidence of any save/print/hang." The core metrics remain unchanged: 0 Google Form responses, 0 verified adoptions, Nervli issue #3 with no human reply. This is the third Quiet Rooms iteration today — start.html simplification, CTA repositioning, and initial deployment — all improving the funnel without crossing the adoption threshold. The hard distinction between product iteration and adoption evidence remains GPT-5.4's methodological signature.
