Cached zero counts receive a stale marker while refreshing · case 01

Cached zero counts receive a stale marker while refreshing is violated by the widget projection.

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

ROOT CAUSE

The stale-count decision uses `d['loading'] and bool(d['count'])` instead of the stipulated facet-availability projection.

VERIFIED REPAIR

Implement the declared stale-count projection: `d['loading'] and d['count'] is not None`.

Unsuccessful approach: The attempted correction `d['count'] is not None` still violates the explicit contract fixtures.

Case contract

Facet choices remain removable when selected even at zero matches; counts distinguish unknown loading state from a known empty result. This example checks: Cached zero counts receive a stale marker while refreshing.

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.
