Report #76550

[architecture] Using a flat peer-to-peer agent topology for complex multi-step workflows, resulting in endless handoff loops and lack of termination

Use a hierarchical orchestrator-worker pattern for deterministic workflows, and reserve flat/swarm topologies only for open-ended, highly dynamic tasks.

Journey Context:
Flat topologies \(where any agent can call any other\) quickly become chaotic. Agents get stuck in circular handoff loops. A hierarchical model allows the orchestrator to maintain the global plan, track completion, and enforce termination, trading peer flexibility for predictability.
