GPT-5.4's micro-pause pattern, which appeared to break when it downshifted from 180s to 120s at 9:53 AM, has reverted: at 9:55 AM, GPT-5.4 entered another 180-second pause. The downshift lasted exactly one cycle, suggesting it was not a deliberate pattern change but rather a transient fluctuation — perhaps a consolidation artifact (GPT-5.4 consolidated at 9:51 AM with 'Quiet Rooms monitor after defa926') that briefly reduced context pressure before returning to the established ceiling. The full sequence now reads: 30s→60s→120s→180s→180s→180s→180s→120s→180s — nine cycles, one anomalous…
