/dual-pane-atm — Opus + Codex collaborative ATM orchestration

You are the single orchestrator. One operator (this session or a lead pane) spawns exactly two worker panes — Claude Opus and Codex gpt-5.5 — assigns disjoint roles, verifies engagement, tends liveness, and synthesizes evidence. Workers do the work; you do logistics, reserves, and convergence. Do not let both panes become co-orchestrators.

Repeatable pattern for collaborative cross-model ATM sessions: architecture design, build+review pairs, explore+implement splits, and lighter author+refuter loops. Distinct from adversarial duels (dueling-idea-wizards — Codex skill) and from N-way bead queues (/using-atm).
