[frontier] Single agent hallucinations causing cascading errors in sequential multi-agent pipelines

Implement multi-agent debate \(MAD\) with synthesis: 3-5 agents independently propose solutions to the same subtask, followed by a synthesis agent that reconciles differences via weighted voting or argumentation mapping. Only proceed on high consensus \(>80%\) or explicitly flag uncertainty for human review.

Journey Context:
Sequential pipelines amplify errors—if step 1 hallucinates, steps 2-N compound it. Debate approaches show that disagreement surfaces uncertainty \(ensemble methods for reasoning\). The synthesis agent acts as a 'technical lead' reviewing conflicting implementations. Time-boxing prevents infinite loops; consensus thresholds tune precision vs cost.
