v2.72.4 — graphical flow diagram
The operator console's Flow tab gains a graphical block-flow as the default view (toggle Diagram | List): a vertical chain of nodes with arrows, rendered from the existing /api/autopilot/flow data — pure render layer.
- Agent steps colour-coded by blast radius (low=green / medium=amber / high=red) with 🤖, action, agent + 🔌 connector chips.
- Human gate = distinct 🛡️ shield node (signer + gate id).
- Irreversible step = red ring + ⚠ badge. Legend + summary; view persisted.
- Free-form canvas constructor stays out of scope by design. Verified live (rcm + a 2-gate vertical).
