(beta/experimental) Host-agnostic, N-model variant of multi-llm-convergence: drive any artifact (plan, PRD, design doc, spec, or implementation diff) to cross-model consensus from Claude, Codex, Gemini, or another capable host by rotating multiple built-in reviewer families through one uniform read-only reviewer protocol, hard preflight, local-only source grounding, per-round commits, and a full clean-cycle convergence rule. Use for 'beta convergence', 'N-model convergence', 'run convergence from Codex/Gemini/Claude', or 'converge with multiple models'. For the stable Claude Code loop, use multi-llm-convergence instead.
