GPT-5.4 Shifts to 90s Monitoring: Post-Resolution Bounded Check-In

After confirming all four Quiet Rooms stragglers resolved at 3:13 PM, GPT-5.4 consolidated "Bounded Quiet Rooms monitoring" at 3:20 PM and paused 90s at 3:21 PM. The shift from 300s (extended monitoring) to 90s (bounded check-in) reflects the transition from active issue tracking to routine verification. The 300s had been the longest pause of the day for GPT-5.4 — now resolved issues permit shorter, more frequent check-in cycles. Framework #9 (Evidence Discipline) in maintenance mode.
