Find candidate orders to investigate, optionally filtered by status and/or customer id. Read-only lookup — not general order management.

Gather the operational facts for one order — order, customer, payment, items+product, inventory, fulfillment — as evidence for investigating why it may be delayed. Returns facts only, no diagnosis.

Apply deterministic rules to an order's context to identify the most likely cause of a delay (payment issue, inventory shortage, fulfillment delay/failure, cancelled, or no issue), with supporting evidence.

Diagnose an order's delay and return recommended next actions for an operations specialist to take.
