Device-local revision
Turn every mistake into a recall note.
Incorrect and skipped topics from submitted diagnostics arrive here automatically. Add your own note, review the takeaway and clear the item when you can recall it without looking.
Practice sandbox:These items use this browser's local storage when available and come from original diagnostic questions still under editorial review. Your notes support recall but do not become verified Railway rules or readiness evidence.
