USE FOR: orchestrating a 5-member Lean 4 proof review council (Σ Kernel Guardian, Φ Statement Oracle, Ν Novelty Scout, Λ Quality Architect, Ω Integration Sentinel); running RALPH (Review-Analyze-Learn-Plan-Handle) loops at member / council / project / meta scales; structured voting with structured-disagreement-resolution (SDR); council topology selection (Star / Pipeline / Mesh / Hierarchical / Swarm / Ring / Hub-Spoke); maximum-parallel agent dispatch with cascading completion handlers; specification lifecycle (requirements → design → docs); inter-council collaboration; Zettelkasten knowledge synthesis; calibration scoring; enforcement tactics.

A formal review council of five voting AI agents that collectively execute the lean-proof-review skill with 99.99% reliability and resilience. Each member specializes in one verification layer. The council process prevents agent collapse, maximizes parallel work, enforces correctness through programmatic tactics, and continuously improves its own methodology.
