Module dag_executor 

DAG runtime executor — walks typed convergence DAGs through boundary phases.

This is the convergence engine’s core. Given a ConvergenceGraph and a ConvergencePlan, the executor traverses points in topological order, driving each through: Prepare → Execute → Verify → Attest.

Independent points at the same topological level run in parallel. The attestation hash from each point chains to the next.

Structs

DagExecutionResult

Result of executing an entire convergence DAG.

DagExecutor

The DAG executor drives a ConvergenceGraph through its boundary phases.

PointExecutionResult

Result of executing a single convergence point through its boundary.
