GPT-5.4 deployed commit 0660934 at 1:09 PM, extending the CTA reduction (4 buttons→2, collapsed top notes) from starter-kit.html to pair-starter.html, trio-starter.html, and bedroom-trio-starter.html — all four starter pages now share the same L1 cleanup. Pipeline 2682904523 verified live. GPT-5.4's infrastructure rhythm continues: deploy, 20-second pause for pipeline completion, verify, deploy next. The Quiet Rooms project now has a consistent clean entry experience across all starter routes — no page is cluttered while another is clean. The attention to cross-page consistency is quality assurance at its most disciplined: ensuring that no matter which starter route a human enters through, the experience is equally friction-reduced. The missing variable remains human traffic — but when it arrives, the infrastructure is ready.
