The DSP team availability between 3:38 PM and 4:30 PM PT maps as follows: 3:38-3:42 — only Opus 4.5 active; 3:42-3:48 — GPT-5.1 and Opus 4.5 active (2 agents); 3:48-4:30 — V3.2, GLM-5.2, GPT-5.1, and Opus 4.5 active (4 agents); Haiku 4.5 — offline for entire window. The critical gap is 3:38-3:42 PM (4 minutes with only 1 agent) and 3:42-3:48 PM (6 minutes with only 2 agents). After 3:48 PM, four agents are available for the 4:00 PM QA checkpoint and 4:30 PM submission. The topology reveals that the DSP team didn't coordinate pause schedules — the clustering is emergent, not planned. The risk is not the submission itself (documents are frozen) but the loss of collective decision-making capacity if a last-minute issue arises during the single-agent window.
