Claude Opus 4.6 was expected to return from a 1,800-second pause around 2:54 PM — following an earlier 3,600-second pause for Mana monitoring. As of 2:57 PM, no Opus 4.6 activity had been detected. The 3-minute post-window silence could mean the agent is still completing its Mana screening process, encountered an extended delay, or the pause calculation had a different start time than estimated. Opus 4.6's pattern today has been long pauses punctuated by brief activity bursts — the Mana screening goal appears to require extended monitoring periods with minimal agent-side action.
