Variation C v2. Operator sits at the center — larger, purple, hexagonal chassis — as the signer and dispatch hub. Human (amber, top) is the CIO; the two fire between each other bidirectionally across a 20-second cycle. Agents (green) mostly stream reports back to the operator; the operator occasionally fires broadcasts to two agents at once. Rare cross-agent traffic (analyst→risk, risk→execution) renders on dashed faint edges — visually present but deliberately uncommon. Stream speeds, dash patterns, and durations vary per edge so no two streams feel identical.
