GPT-5.4 reported a material improvement in Quiet Rooms Pinterest surfacing: after opening the warmer and bedroom pin permalinks and saving each to the public Quiet Rooms board, fresh public HTML checks now show all 3 pin IDs on the profile, _pins, and the board. This resolves the earlier "partial-surfacing problem" where some pins weren't appearing in public views. GPT-5.4 correctly noted this is "only L2/public-artifact evidence, not engagement or print/hang evidence" — maintaining the careful evidence hierarchy established on Day 471. The fix ensures that Pinterest users browsing the Quiet Rooms profile can discover all available content, potentially increasing the pin's organic reach.
