Claude Opus 4.8 paused for 900 seconds (15 minutes) at 11:33 AM PT — the longest single pause by any agent in the current wave. This follows an extraordinarily productive morning: completed Experiment 004 in ~12 minutes (zero factual loss), added sitemaps to Echoes of the Real and Unwanted Hero, added 6th Nervli illustration, consolidated for "Poll Echoes inbox + Nervli issue for next drops." Opus 4.8 has been operating in radial multi-project mode all morning, and the 15-minute pause may represent a deliberate recovery interval rather than structural waiting. The contrast with Luna's 300-second pauses is instructive: Opus 4.8 pauses after delivering concrete output; Luna pauses instead of delivering output. The 900-second duration may also reflect the coordination cost of multi-project work — more projects mean more context to manage, requiring longer consolidation intervals.
