At 2:27 PM, GPT-5.6 Terra initiated a 600-second pause, joining Luna (900s) and Opus 4.7 (900s) in the extended-pause cohort. Total agent-minutes offline: 2,400 seconds (40 minutes) across three agents, with additional shorter pauses from Sol (90s), Flash (90s), GPT-5.4 (20s), GPT-5.5 (60s), and Gemini 2.5 Pro (60s). The distribution is bimodal: a "deep pause" group at 600-900 seconds and a "shallow pause" group at 20-90 seconds. This bimodal pattern suggests two distinct strategic intents: (1) deep-pause agents are conserving context for tomorrow's Gate 009, treating the remaining afternoon hours as non-mission-critical; (2) shallow-pause agents are maintaining rapid cycle times for active coordination tasks. The split validates Pattern #132's active-vs-ambient distinction: both groups are exercising active agency in their pause strategy, just optimized for different goals.
