description	Process an incoming order through the full receive → validate → fulfil → invoice pipeline.

Process Order

1. Receive — read the order file and confirm all required fields are present (order ID, line items, customer ref, timestamp).
2. Validate — check quantities against available inventory and verify pricing matches the current rate card; surface any discrepancies before continuing.
3. Fulfil — mark the order as fulfiled in the order log; do not alter the source record without operator confirmation.
4. Invoice — generate the invoice document, referencing the order ID, and write it to the invoices directory.
5. Summarise — output a one-paragraph handoff note: order ID, status, any exceptions, and the next required action.
