Report #46317

[frontier] Centralized agent orchestrator becomes a bottleneck and single point of failure in complex multi-agent workflows

Replace star-topology orchestrators with Directed Acyclic Graph \(DAG\) based execution where agents publish to a shared event bus, and workflow logic is defined by dependency graphs with per-node retry policies and checkpointing, enabling parallel execution and partial failure isolation.

Journey Context:
Centralized controllers \(early LangGraph patterns\) couple availability to the orchestrator node. DAG topologies enable fan-out to multiple agents simultaneously, deterministic replay via persisted checkpoints at each node, and graceful degradation when individual agents fail—critical for production reliability at scale.
