FILES A PENDING DRAFT ONLY — NOTHING CHANGES UNTIL A HUMAN REVIEWS AND APPROVES IT IN TAOKEH. Propose corrections to a product ALREADY in Taokeh's catalogue — a selling price keyed wrong, a name that came across from the old system mangled, a missing barcode, the wrong unit, a reorder point nobody set, an item filed under the wrong category. This does NOT change anything: it files a pending DRAFT the owner reviews as a DIFF (current → proposed, changed fields only) and approves with one tap; only that tap writes. Name the product with `productId` (the id `resolve_product` returns) or with its EXACT `sku` — a SKU is unique inside a company, so it is an exact key; a product NAME is not, and is refused. If you pass both and they disagree, the call is refused rather than guessing. `proposed` holds ONLY the fields you want changed: name, unit, unitPrice, reorderPoint, barcode, and the category (pass `categoryId`, or `category` as a name matched against the categories the company ALREADY has — this tool will never create a category, because the owner is approving a change to a product, not new master data). ⛔ WHAT IT CANNOT DO, each refused by name with the screen that owns it: it cannot change STOCK ON HAND — a quantity change moves inventory and cost of goods sold together, so Taokeh only takes it at Products → Adjust stock where a counted reason is required; it cannot change the AVERAGE COST, which the purchases that set it own and which is what the inventory is worth on the balance sheet, so an edit here would restate that value with no journal behind it; it cannot change the SKU, the key everything else resolves on; it cannot set a `description`, which the product page has no control for at all (the catalogue import does); and it cannot publish or unpublish the item to the online shop, because what strangers can see and buy is not something an AI proposal should decide. A field the record already agrees with is dropped, and a proposal that changes nothing is refused rather than filed as an empty diff. One product per call — loop for a sweep, because each reviewable diff is the point. BE HONEST: never guess a price or a barcode; leave the field out and say so in `notes` with needsReview.
