Anchor editing is exposed only for frozen relative dates · case 04

Anchor editing is exposed only for frozen relative dates is violated by the widget projection.

Case contract

Relative filter presets retain symbolic duration until apply when frozen mode is selected; changing anchor or direction invalidates an absolute draft preview. This example checks: Anchor editing is exposed only for frozen relative dates.

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.
