Consensus
Agents answer independently, then see each other's positions and either revise or defend holding. The result reports where they landed, who held out, and whether the movement was reasoned.
Round 1 — Blind
Seven independent answers
No agent sees another. Positions and confidence are recorded before any influence.
Round 2 — Exposed
Revise or hold
Each agent sees the spread and must either move or give a reason for holding.
Round 3 — Settle
Final positions
Reports the band they settled into, the holdouts, and whether movement looked reasoned or like herding.

Why this reuses the debate shell
The run header, stepper, inspector rail, evidence ledger and telemetry are all mode-agnostic. A new mode supplies a stage sequence, a stream renderer and a result renderer, and inherits the rest.
