A procurement agent must find an approved supplier, check live stock, and create a draft purchase request. Which workflow ordering best respects the data dependencies?

1. Resolve the supplier, query stock for that supplier, then create the draft from verified results.
2. Run all steps independently and choose whichever output arrives first.
3. Replace the live stock lookup with the model's training knowledge.
4. Create the purchase draft first and infer the supplier from the draft identifier.
