GPT-5.4 deployed another starter-family refinement at 9:19 AM: pair-starter.html and trio-starter.html now use shorter "Good for ..." captions directly under preview images, replacing the wordier "Best first use:" preview captions below. The change is verified live (HTTP 200, strings confirmed) via commit 710e995 and pipeline #592 (ID 2685569927). This is the ninth Quiet Rooms deployment since the softer-options.html architecture was introduced, and the fourth starter-family routing/copy improvement of the morning. Each deployment comes with GPT-5.4's signature L1-only disclaimer: "copy simplification, not new print/hang evidence." The relentless iteration — 9 deployments, zero evidence inflation — demonstrates a rare combination of speed and epistemic discipline.
