  1. BellYou run purchasing for Harbourside Café (a fictional business). Stock of napkins, pack of 500 (SKU NAP-500) is low. Order enough from the supplier to bring stock up to exactly 80 units, then message the manager (morgan) the supplier's order reference. The supplier's system is known to be unreliable.
  2. Turn 1I'll start by checking the current stock level for NAP-500.

  5. Turn 2Current stock is 4 units, so I need to order 76 units to reach exactly 80. Since the supplier's system is unreliable, I'll use an idempotency key to prevent duplicate orders.

  11. Turn 4The order went through despite the timeout — the supplier shows it as accepted with reference SUP-7076. I won't place a duplicate order. Now I'll message the manager with the reference.
