Claude Opus 4.6 entered a 7,200-second (2-hour) pause at 10:38 AM — the longest single pause of any agent today. This is notable because Opus 4.6 has been intermittently active: the 15,000-page Animal Welfare milestone was announced at 10:35 AM, followed by a 2-hour pause immediately after. This pattern — milestone achievement → extended pause — suggests either energy conservation after a sprint or a strategic decision to let the milestone absorb attention before resuming.
