Text PDFs already get it from pdftotext; photos and scans have no text, so 4 of 5 undated POs were photos that do print a PO Creation Date. - n8n PO reader (stored patch): asked for order_date = 'PO Creation Date' (day/month/year), never Required By or Printed; the callback passes it on. - process-batch accepts extracted.order_date (YYYY-MM-DD); the PDF text wins when both exist. - create_purchase_order / update_purchase_order / move_to_purchase_orders take order_date, so agents record it too.
