A filter submission masks settled result counts until acknowledged · case 01

A filter submission masks settled result counts until acknowledged is violated by the widget projection.

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

ROOT CAUSE

The result-label decision uses `str(d['count'])` instead of the stipulated applied-status projection.

VERIFIED REPAIR

Implement the declared result-label projection: `'updating' if d['sent']>d['ack'] else str(d['count'])`.

Unsuccessful approach: The attempted correction `'updating' if d['sent']!=d['result'] else str(d['count'])` still violates the explicit contract fixtures.

Case contract

The applied-filter summary distinguishes settled, pending and failed draft updates, and uses the server-acknowledged filter revision for result badges. This example checks: A filter submission masks settled result counts until acknowledged.

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.
