A drag must originate from a group containing the criterion · case 01

A drag must originate from a group containing the criterion is violated by the widget projection.

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

ROOT CAUSE

The source-membership decision uses `True` instead of the stipulated group-reparent projection.

VERIFIED REPAIR

Implement the declared source-membership projection: `d['criterion'] in d['source_rows']`.

Unsuccessful approach: The attempted correction `d['criterion'] in d['target_rows']` still violates the explicit contract fixtures.

Case contract

A filter-builder drag moves a criterion between explicit group identities, rejects descendant cycles, and retains operator grouping when flattening is unsafe. This example checks: A drag must originate from a group containing the criterion.

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.
