Report #7794

[architecture] Unpredictable routing and unmaintainable spaghetti code from peer-to-peer agent topologies

Use a hub-and-spoke \(orchestrator/supervisor\) topology for complex workflows, where a central agent handles all routing and aggregation, instead of allowing agents to call each other directly.

Journey Context:
Peer-to-peer agent meshes \(where any agent can hand off to any other\) seem highly flexible and 'emergent'. In practice, they create unpredictable execution paths, making debugging impossible and often leading to circular dependencies. A hub-and-spoke model centralizes control flow, making the system deterministic and auditable. Tradeoff: the orchestrator becomes a bottleneck and single point of failure, but predictability is usually worth the latency cost in LLM systems.
