[synthesis] Adding more agents increases end-to-end failure rate multiplicatively instead of averaging out errors

Prefer a single agent with reflection for sequential reasoning; use central orchestration with validated sub-agents only when decomposition is clearly beneficial. Cap pipeline depth at 5-6 steps.

Journey Context:
If each stage has a 30% error rate, a 4-stage pipeline succeeds only about 24% of the time. Peer-to-peer 'bag of agents' architectures amplify errors roughly 17x versus single-agent baselines, while centralized orchestration limits amplification to about 4x. SWE-Dev results show simple self-refinement systems beat heavy multi-role workflows because they preserve global context. Decomposition is valuable for parallelization or specialized tools, not for sequential reasoning.
