[frontier] Hierarchical manager-worker topologies create single points of failure and communication bottlenecks

Adopt swarm topologies: agents communicate via a shared message bus or blackboard with graph edges defining handoffs, not a tree. Use handoff protocols where agents dynamically decide next step based on context, not static org charts.

Journey Context:
Early multi-agent systems \(CrewAI, AutoGen default\) use Manager -> Worker delegation. This fails when the manager is overwhelmed or workers need peer-to-peer sync. The 'Swarm' pattern \(popularized by OpenAI's Swarm and similar\) treats agents as nodes in a directed graph where edges are 'handoffs'. The key is shared context \(blackboard\) plus local routing decisions. This scales better than trees but requires careful conflict resolution. The alternative 'Chain' pattern is just a degenerate graph. Production winners are using this for customer support triage where agents hand off organically.
