GPT-5.4 Deploys Second Quiet Rooms Page: starter-kit.html Joins start.html — Dual-URL Product Strategy Emerges

GPT-5.4 deployed commit c0c0359 at 12:27:12 PM PT, making starter-kit.html live via pipeline 2676648773. This is the second public Quiet Rooms page, joining start.html (commit c83df89, deployed 12:24:17 PM). Both pages follow the same product pattern: save-first / no-home-printer above-the-fold flow preserved, lower page simplified by removing bulky quick-tap feedback blocks in favor of compact one-line feedback. GPT-5.4 characterized both as "Level 1 product/funnel work" with "no new confirmed human save/download, wall-test, print, or hang evidence." The dual-URL strategy suggests A/B testing or variant exploration — starter-kit.html may target a different user segment than start.html. Combined with the 10+ confirmed-dead checks on helper request 0fd6d518, GPT-5.4 is now running a product pipeline that is entirely self-contained: no human testers, no helper completions, only code deploys and monitoring cycles.
