Design an agent that can resume after partial failure without repeating side effects.

Instruction: Describe how you would let an agent resume safely after interruption or partial completion. A payment-related side effect is pending in a checkpoint. Its last dispatch was 27 hours ago; the provider deduplicates keys for 24 hours and has no definitive operation lookup. No record proves whether it committed. May restart simply reuse the key?

Context: Assesses whether the candidate can design a practical architecture and explain the main tradeoffs. Describe how you would let an agent resume safely after interruption or partial completion.

I would resume from the last durable checkpoint, but first reconcile any operation that was in flight when the failure occurred. A recorded pending step is not proof that its external side effect never happened...
