Equality conversion retains the first set operand · case 03

Equality conversion retains the first set operand is violated by the widget projection.

Member previewVariant 3 · 3 implementations · 10 checks per implementation

Case contract

The stipulated filter editor supports equality, set membership and unary presence operators; switching operator updates operand arity rather than executing a query. This example checks: Equality conversion retains the first set operand.

Why this case matters

Filter-widget state and serialization must preserve user constraints while the view changes.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
