Explanation:
Process structure: A workflow with agent executors; Pause mechanism: A human-in-the-loop (HITL) gate; Interruption recovery: Checkpoints.
The process has a fixed execution order and can run for several hours, so an explicit workflow with agent executors is preferable to free-form agent delegation. The requirement to pause at predefined points is a human-in-the-loop requirement: the workflow must be able to suspend and emit a request for approval or operator input. The requirement to resume after worker restarts is addressed by checkpoints. Microsoft Agent Framework checkpoints persist workflow progress, executor state, pending messages, shared state, and outstanding requests so execution can be restored from the last saved point. A retry policy alone re-executes operations but does not reconstruct the complete workflow state after a process interruption. The three selected mechanisms therefore cover structure, controlled pause, and durable recovery as separate but complementary workflow concerns. In production, add telemetry and regression tests around this behavior so changes to prompts, models, tools, or orchestration do not silently alter the intended contract. The selected approach is the one that best matches the platform ' s native execution semantics.
