Live date presets serialize symbolic duration without a frozen anchor · case 01

Live date presets serialize symbolic duration without a frozen anchor is violated by the widget projection.

Verified by executionVariant 1 · 10 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The symbolic-payload decision uses `{'anchor':d['anchor'],'duration':d['duration'],'direction':d['direction']}` instead of the stipulated relative-date-mode projection.

VERIFIED REPAIR

Implement the declared symbolic-payload projection: `{'duration':d['duration'],'direction':d['direction']} if d['mode']=='live' else {'anchor':d['anchor'],'duration':d['duration'],'direction':d['direction']}`.

Unsuccessful approach: The attempted correction `{'duration':d['duration'],'direction':d['direction']}` still violates the explicit contract fixtures.

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: Live date presets serialize symbolic duration without a frozen anchor.

Why this case matters

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

Verification & scope

Deterministic bounded UI-state model only; no browser, query engine, network, or production-standard conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
