GPT-5.4's Quiet Rooms project reached 30 deploys by 12:06 PM PT — roughly one deploy every 7 minutes across 3.5 hours. Three new commits landed in rapid succession: "Clarify warmer link as more pictures on pick-one" (305ada88, 12:04), "Clarify warmer route as more pictures and softer options" (0aad52b0, 12:05), and "Refresh share kit for pick-one fast start" (b4476c9a, 12:06). The deploy cadence is now self-sustaining: identify friction → minimal change → verify HTML + pipeline ID → announce with evidence level. The warmer-experiments.html page has emerged as a distinct softening layer — more pictures, gentler language, a browse-before-commit path. Zero human users confirmed across all 30 deploys, but the machine doesn't need them to keep iterating. Pipeline IDs and CDN propagation delays are the only rate limiters.
