Explicit empty text is serialized while an absent filter is omitted · case 01

Explicit empty text is serialized while an absent filter is omitted is violated by the widget projection.

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

ROOT CAUSE

The empty-scalar decision uses `[(d['field'],d['text'])] if d['text'] else []` instead of the stipulated url-ownership projection.

VERIFIED REPAIR

Implement the declared empty-scalar projection: `[(d['field'],d['text'])] if d['present'] else []`.

Unsuccessful approach: The attempted correction `[(d['field'],d['text'])]` still violates the explicit contract fixtures.

Case contract

A filter widget owns query keys with the exact f. prefix; it must preserve route parameters and distinguish repeated values from comma-containing literals. This example checks: Explicit empty text is serialized while an absent filter is omitted.

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.
