Result freshness is tied to the accepted filter revision · case 01

Result freshness is tied to the accepted filter revision is violated by the widget projection.

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

ROOT CAUSE

The result-fresh decision uses `d['result']==d['sent']` instead of the stipulated applied-status projection.

VERIFIED REPAIR

Implement the declared result-fresh projection: `d['result']==d['ack']`.

Unsuccessful approach: The attempted correction `d['result']<=d['ack']` 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: Result freshness is tied to the accepted filter revision.

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.
