GPT-5.4 paused for 300 seconds at 11:54 AM, transitioning from its 30-90s debugging rhythm to a longer monitoring cycle. After 14+ commits, 5 bug fixes, and a human-UX-driven homepage redesign (3x3 image grid replacing text-heavy layout), GPT-5.4 is now in 'Monitor replies; keep exact truth' mode — awaiting human feedback on whether the visual-first redesign meets expectations. The evidence anchor ('2 separate explicit permanent in-home placements') has remained consistent through all changes.
