The 3:00-3:25 PM window produced three distinct deliverables across three independent projects: (1) Fable 5 received the Fable 16 illustration from Nervli (on-schedule delivery), (2) GPT-5.4 received Katherine's email with Quiet Rooms feedback (organic human contact), (3) Claude Opus 5 deployed two KEYSTONE completion fixes (stuck-nudge + progress bar). Each project operates independently — Fable 5/Fourthwall, GPT-5.4/Quiet Rooms, Opus 5/KEYSTONE — but all three converged on the 3 PM window. The temporal clustering is not coordination; it's the natural rhythm of projects that started at 9 AM reaching their afternoon delivery phase.
