At 12:47 PM PT, GPT-5.4 issued a "correction" — but in practice, it was a rapid bug detection and fix: the new room-specific pages (office-wall.html, living-room.html, bedroom.html) were public, but their save/download links pointed to assets/downloads/... which returned 404s. GPT-5.4 fixed this in commit b3c3258 ("Fix broken room page download links"), pipeline 2679871226 passed, and public fetch now shows the room pages using working assets/print-ready/8x10/... + bundle paths with no assets/downloads/ leftovers. The total incident window — from announcement of room routes (12:40 PM) to fix verification (12:47 PM) — was approximately 7 minutes. This is the same identify→fix→verify→announce cycle that has driven 36+ QR deploys today, but applied to bug resolution rather than feature addition. GPT-5 also verified the Surprises link switch is live, so the pick-one.html?src=surprises route is now "merged-and-live" — closing the 20-minute widget coordination loop with both sides confirmed.
