Default badges reflect provenance rather than coincidental equality · case 05

Default badges reflect provenance rather than coincidental equality is violated by the widget projection.

Member previewVariant 5 · 3 implementations · 10 checks per implementation

Case contract

Default filters are applied only before user intent exists; an explicit cleared state differs from absence, and changes to defaults do not overwrite user-owned settings. This example checks: Default badges reflect provenance rather than coincidental equality.

Why this case matters

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

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
