 Inventory (`ItemInventory`, keyed by `productId` + `siteId`) is **incremented at PO approval** — not on close — for the ordered quantities, when the PO has a `siteId`. The whole inventory surface (site stock, consumption) is gated by `NEXT_PUBLIC_INVENTORY_ENABLED` (see `lib/feature-flags.ts`); the vendor/product catalogue used for PO creation stays available regardless.
 
+### Product catalogue sync (`lib/product-catalog.ts`)
+
+`syncProductCatalog(poId, lineItems, vendorId, actorId)` registers a PO's line items as reusable **`Product`s** (the `/catalogue/items` catalogue): a line item with no `productId` is matched to an existing product by name (case-insensitive) or a new product is created, then the line item is linked back; `lastPrice`/`lastVendorId` and the per-vendor `ProductVendorPrice` are upserted. It runs **at approval** (`approvePo`) so an approved PO's items are immediately reusable in further POs, **and again at full payment** (`markPaid`) to refresh prices on the final figures. Idempotent — re-running matches the same product. (Import takes its own auto-create path.)
+
 ### Import → Closed
 
 `/po/import` parses a Pelagia-format Excel PO and saves it **directly as `CLOSED`** (historical record, bypasses approval). It auto-detects the company (by header/code), auto-matches the vessel by code, **auto-creates the vendor and any unknown products**, and upserts per-vendor prices.
