The reader always read the slip date (and receiver, site name, customer
VAT, supplier registration), but dn_batch_notes never had those fields,
so they were dropped on save and every receipt was dated the moment it
was posted. The Financial dashboard dated orders by upload date, so 24
of 41 POs (R7.08M) sat in no month and deliveries piled up in the month
they were booked: 'R1.1M ordered, R2.4M delivered'.
- scripts/pb-add-dn-dates.py: adds the five header fields,
delivery_notes.posted_at and purchase_orders.order_date (applied).
- scripts/dn-backfill-dates.py: filled 270 documents from the stored
readings, moved 192 receipts to their slip date (booking time kept in
posted_at) and read 36 PO order dates from the PDFs (applied; replaced
values in docs/audits/2026-10-11-dates-backfill-backup.json).
- Posting refuses a slip without a delivery date instead of using today;
receipts record posted_at. The review page shows the date and locks
Post with a plain message when it is missing.
- PO intake reads 'PO Creation Date' from the PDF text (pdftotext).
- Dashboard tile and monthly chart date orders by order_date only; an
order without one is undated, never put on its upload month.
