Check locally which products a marketplace will refuse and why — missing price, unusable price, blank name, unmapped category — grouped by what fixes them, without calling the marketplace. The response separates `blocked` (these products do NOT go out) from `warnings` (these DO go out, but probably will not be published as the merchant expects: a price in a currency the platform does not name, no words of their own in a language the channel reads, a placeholder description, characteristics the marketplace does not recognise). Local checks exist for prom, rozetka, google_merchant and olx; other platforms report their connection state through get_marketplace instead. If the channel is not connected the call fails with NOT_FOUND ("<channel> is not connected in this workspace") instead of reporting an empty channel — use list_marketplaces to see which are connected. This never publishes anything: it reports what would happen.
