Bulk-change counts report newly added eligible choices · case 01

Bulk-change counts report newly added eligible choices is violated by the widget projection.

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

ROOT CAUSE

The bulk-added-count decision uses `len(d['visible'])` instead of the stipulated bulk-facet-selection projection.

VERIFIED REPAIR

Implement the declared bulk-added-count projection: `sum(x not in d['selected'] and x not in d['disabled'] for x in d['visible'])`.

Unsuccessful approach: The attempted correction `sum(x not in d['selected'] for x in d['visible'])` still violates the explicit contract fixtures.

Case contract

Bulk selection acts on eligible visible choices, preserves hidden selections and reports mixed state over the eligible visible subset only. This example checks: Bulk-change counts report newly added eligible choices.

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.
