Operators can now type per-upload instructions for the AI extraction
step in the Pricelist upload form. The notes go into a new
`raw_price_list.notes` field that the n8n workflow reads and
injects into the LLM user message as per-upload context.
Common uses:
- "Brand is JEI" → AI stamps every item with brand="JEI"
- "Apply 30% markup" → Code node regexes this out for selling_price
- "All prices in ZAR excl. VAT" → AI uses ZAR
- "Page 4 has discount codes" → AI skips those rows
Also auto-populates `raw_price_list.file_name` (the original
browser-side filename) on upload — PB slugifies the upload to a
token stored inside supplier_file, so without this field the
operator saw the slugged version. Existing rows backfilled by the
admin script.
The `log_summary` field is now reserved for the AI's write-back
summary (set by the n8n workflow after extraction). It was
previously operator-editable on the form, which was wrong —
overwriting it clobbered the AI's output.
New migration: scripts/migrations/2026-06-30-add-pricelist-notes.ts
(idempotent, only adds `notes` if missing — `file_name` was
added manually via the PB admin UI before this commit).
doc/pricelist-extraction.md updated with the n8n LLM user message
shape, the markup regex, and the notes field's role in the pipeline.
