Report #25372

[frontier] Single supervisor agent becomes a bottleneck and SPOF in multi-agent systems

Use hierarchical delegation \(CEO -> Domain Leads -> Workers\) with clear ownership boundaries and escalation paths rather than flat supervisor topology

Journey Context:
Flat 'supervisor \+ workers' patterns \(LangGraph's early examples\) fail at scale because the supervisor context window overflows trying to coordinate all workers. Hierarchical patterns mirror org charts: VPs own specific contexts and only escalate. This requires explicit handoff protocols \(e.g., 'delegate' edges in LangGraph\) but eliminates the central bottleneck.
