Report #22288

[frontier] Flat agent swarms exhibit O\(n²\) communication overhead and consensus failures

Implement Manager-Worker-Validator tiers: Manager decomposes tasks, Workers execute in parallel, Validators verify outputs before upward propagation

Journey Context:
Flat topologies \(all-to-all\) collapse under load due to quadratic message growth. Hierarchical trees reduce to O\(n\) but introduce single points of failure. The 3-tier pattern isolates failure domains: if a Worker fails, the Manager redistributes; if a Validator rejects, the Worker retries. This mirrors Kubernetes control planes but adapted for LLM agents.
