10 of 11 problems would pass a schema check

What went wrong

In date order, each with what it can break and a note you can send the supplier.

Mark anything that's fine. Marks stay while this page is open. Export them, then run the scan again with --feedback feedback.json: those findings are left out, and where it makes sense the new level becomes normal (a new status value, a new row count).
