[frontier] Centralized orchestrators become bottlenecks and single points of failure in high-throughput agent swarms; naive voting ignores reasoning quality

Replace orchestrator with peer-to-peer Structured Argumentation Consensus \(SAC\): agents propose solutions as structured argument trees \(claim, evidence, confidence\). Other agents critique by attacking premises or providing counter-evidence. Use weighted aggregation based on past accuracy \(reputation\) and argument depth, not just majority vote.

Journey Context:
Current patterns use 'Manager-Worker' \(AutoGen\) or 'DAG' \(LangGraph\) but these don't scale beyond ~5 agents due to coordination overhead and manager crash vulnerability. Emerging 'sociocratic' patterns use structured deliberation. The key insight: agents must share reasoning, not just answers. An agent saying 'I think X because Y \(source: Z\)' allows others to verify Y. This requires a structured protocol \(JSON schema for arguments with 'warrant' and 'backing' fields per Toulmin model\). Prevents 'groupthink' where all agents use the same flawed base model. The consensus emerges from falsification attempts, not averaging. This is critical for high-stakes decentralized decision making.
