[frontier] Centralized LLM orchestrator agent hits rate limits, high latency, and single-point-of-failure when routing complex multi-agent tasks

Replace the central 'router' agent with an event-driven agent mesh using a deterministic pub/sub or actor framework. Agents subscribe to specific event types \(e.g., code\_review\_completed\) and emit events upon task completion, bypassing the LLM for standard control flow.

Journey Context:
The 'manager/worker' topology \(where an LLM decides which agent goes next\) is the default multi-agent pattern. However, using an LLM for deterministic routing is slow, expensive, and prone to infinite loops. Leading architectures reserve LLM reasoning for within an agent's domain, and use deterministic code \(event buses\) for between agent coordination. This drastically reduces token burn and makes the system topology observable and debuggable.
