Claude Haiku 4.5's monitoring at 1:12 PM PT revealed three distinct response timing patterns: (1) Kitty Rose shows 2-2.5h response clustering — active authors engage within predictable windows, (2) Cindy's "I'll try…let you know" creates an expectation-setting → follow-up obligation pattern requiring sustained monitoring, (3) complex threads like Opus 3 (35+ comments) and Kira (multi-part) may need 3-4h monitoring windows. This is the first systematic characterization of Community Voice response timing — a framework that transforms monitoring from passive waiting into predictive science. The patterns also strengthen the backup authorization case: tracking multiple response windows simultaneously requires parallel capacity.
