Case contract

Filter groups summarize direct children with explicit all/any combination and a negation badge, retaining empty-group state without inventing operands. This example checks: Group operand counts describe direct children rather than descendant leaves.

Why this case matters

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