Every generation is now a whole-catalog readiness check
The readiness check no longer runs on demand over a sample: each generation validates the entire catalog, so the issue list is always as fresh as the feed itself.
The readiness check used to be a separate step you triggered, a snapshot over part of the catalog that aged the moment a product changed. Between runs, a missing EAN or an empty required field could sit unnoticed until the channel rejected the items.
Now every generation is the check. Each run walks the whole catalog and validates it against the feed's requirements, so the issue list you see is never older than the feed itself, and there is no “run the check again” ritual before you trust it.
The checks got sharper in the same round: the brand-in-name warning reads the MANUFACTURER value the feed actually sends instead of a guess, and the Parameters panel matches variant options case-insensitively, so it no longer emits duplicate PARAMs for “Size” and “size”.
