Owner ruling 2026-09-09: the order configuration page upsells addons "suitable for the hosting type", and its running total has to match what checkout charges to the minor unit. That second half is what makes an addon a basket LINE rather than a second purchase path — a total including something the basket cannot hold would be a second place that adds money up. The price is computed by the server from the catalogue in the cart's own currency; anything sent by the client is ignored. Which addons this basket may buy is read from its own plan line, never from the request: this endpoint is anonymous, so a caller-supplied product line would put every PBN-only addon one request away from any basket. A basket with no plan in it can buy only the addons sold on every line. 422 covers all three refusals — withdrawn (no fulfilment handler is registered, so we could take the money and run nothing), not sold on this product line, or already in the basket. One of each service per basket.
