Report #68792

[architecture] Running agents in parallel where tasks implicitly depend on each other causing deadlocks

Model dependencies as a Directed Acyclic Graph \(DAG\) and execute using a topological sort, ensuring agents only run when their upstream dependencies are resolved.

Journey Context:
Naive parallel execution \(fan-out/fan-in without dependency mapping\) fails when tasks are interdependent. LLM planners often generate parallel sub-tasks that implicitly rely on each other's intermediate state. A DAG enforces explicit, deadlock-free execution ordering, trading off the simplicity of a flat list of tasks for guaranteed execution safety and parallel efficiency.
