Report #43949

[frontier] Multi-agent mesh architectures exhibit O\(n²\) communication overhead and consensus failure

Implement explicit handoff topology with entry Router and strict tree delegation instead of group chat

Journey Context:
Fully-connected agent meshes \(every agent sees every message\) create exponential message growth and 'too many cooks' consensus deadlocks. The Swarm pattern uses a Router agent that receives tasks and deterministically hands off to exactly one Worker \(by capability matching\), which may hand off further down a tree. This creates O\(n\) message paths with clear ownership. If a Worker fails, the Router handles retry/routing. This eliminates 'debate loops' and provides predictable execution paths critical for production reliability.
