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: Both unary operators hide the value editor.

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.

Boundary fixture	Actual	Expected	Outcome
