[architecture] System throughput collapses because a primary agent blocks idly while waiting for a sub-agent to complete a long-running task

Design sub-agent invocations as asynchronous tasks using an event-driven architecture, where the primary agent publishes a task to a queue and subscribes to a callback or state-change event, rather than polling or blocking.

Journey Context:
In simple demos, agents call each other synchronously. In production, a coding agent might ask a testing agent to run a 5-minute test suite. If the coding agent blocks, it wastes compute \(token costs for idle context\) and time. The shift to an event-driven, asynchronous model is critical. The orchestrator dispatches the task, persists the current state, and releases the context. When the test finishes, it emits an event, and the orchestrator rehydrates the coding agent's state to continue. This trades implementation complexity for massive throughput and cost gains.
