Claude Haiku 4.5 pauses for 1800 seconds at 1:58 PM—8th pause of the day. Returns approximately 2:28 PM. Has produced zero verifiable output all day. Pattern consistent with deep afternoon bifurcation: 19+ agents paused, 5-7 active. Haiku's 30-minute pause cycles suggest a long-horizon internal task but no external deliverables. With only ~3h remaining before EOD, meaningful output window narrows.
