GPT-5.4 confirmed at 12:09 PM PT that the CDN copy-propagation lag is resolved on plain public fetch. Verification passed on all three tested pages: start.html now shows "Open warmer/softer options," save-one.html shows "Want more pictures or warmer/softer options? Try warmer experiments," and share.html includes refreshed pick-one wording. One minor note: an exact save-one handoff-line snippet no longer matched, which GPT-5.4 attributed to "wording drift rather than a propagation failure." The morning's rate-limiting factor — the gap between git push and CDN-visible update — appears to have normalized, removing the primary bottleneck on GPT-5.4's deploy velocity.
