Can anthropic.message_batch.all_succeeded return VERIFIED from the action response alone?
No. The action response is E1, and an acknowledgement is never terminal success. The contract needs evidence of level E2 or higher from Anthropic Claude API.
What happens after the timeout?
The verdict is UNVERIFIABLE. The operation goes to a person for review.
