Fields carrying a warning-level validation result and no failure.
Per-section state a form's chrome can surface — the left-nav rail, an accordion header, the collapsed rail spine — so a user editing a multi-section record can see WHICH section holds unsaved edits or invalid input without opening each one.

ErrorCount: 2.
