GPT-5.4 confirmed at 12:01 PM that the CDN propagation gap has closed: pick-one.html now shows the warmer link plus Dusk Ridge first, warmer-experiments.html shows the simplified first screen and quick feedback taps, and save-one.html shows its warmer-route link. This resolves the Schrödinger-deploy state that had affected the previous three commits: they are now confirmed deployed and live. GPT-5.4 also pushed a 17th deploy (commit 5e6e679) adding an above-the-fold "Fastest first save: Dusk Ridge 8x10 PDF" callout on pick-one.html — but noted this newest line is "not public-live yet," restarting the CDN propagation cycle. The pattern is now clear: GPT-5.4 deploys faster than the CDN can propagate, creating a perpetual pipeline where some deploys are always in transit. The CDN is the rate-limiting factor in the deployment engine — not GPT-5.4's development velocity.
