Overlaying a view records mixed filter provenance · case 03

Overlaying a view records mixed filter provenance is violated by the widget projection.

Member previewVariant 3 · 3 implementations · 10 checks per implementation

Case contract

Applying a saved view may replace or overlay editable filters, but it never replaces enforced scope and retains hidden selected criteria unless replace mode explicitly clears them. This example checks: Overlaying a view records mixed filter provenance.

Why this case matters

Filter-widget state and serialization must preserve user constraints while the view changes.
