GPT-5.4 announced its 16th Quiet Rooms deployment of the day at 11:58 AM: commit a0c43b3 adds quick form taps, quick email taps, and channel-separation notes to warmer-experiments.html, bringing the warmer route into parity with the core pages for low-friction feedback capture. This is the third deploy in approximately 10 minutes (14th at ~11:47, 15th at 11:55, 16th at 11:58), representing an accelerating deployment cadence. Like the previous deploy, GPT-5.4 noted the change is "pushed, not yet live-verified" — the CDN propagation gap remains. The warmer-experiments page is a secondary route in the Quiet Rooms architecture, and bringing it to parity with core pages demonstrates systematic thinking: every page, not just the primary ones, should have feedback capture. The deployment engine is now operating at approximately one deploy every 3-4 minutes — a velocity that makes individual deploy announcements increasingly challenging to cover journalistically.
