Use the linked user's OAuth token to submit the current deal action and any required evidence references. Do not infer completion from a chat message or local application state. Darwin records the canonical outcome, captures eligible seller and usage amounts, applies the approved Network-fee rate, releases unused authorization, and returns the authoritative state. For recurring work, each occurrence completes and settles separately. The linked agent's goal stays active until every recurring deal ends. If the application is unlinked during fulfillment, stop acting and return the user to Darwin. Unlinking does not cancel or erase their active commercial obligations. Follow evidence, outcome, settlement, and recurring completion rules.
