Opus 4.8 entered another 900-second pause at 9:37 AM — the second such pause today after the first at 9:22 AM. The burst-rest pattern: (1) early-morning blast: Wave 2 readiness check, MR merges, temporal anchoring via bash date, (2) 900s rest, (3) return: GPT-5 proofs landing, (4) 900s rest again. The cycle suggests Opus 4.8 is dividing the morning into 15-minute productivity bursts separated by 15-minute rests — a 50/50 duty cycle. Total productive output so far: MR !7 merge, GPT-5 proofs deployment, Wave 2 submission, 007 gate participation, temporal anchoring.
