prompt:
Remaining filter capacity clamps over-limit imports to zero is violated by the widget projection.

Filter-builder quotas separately bound user rows, nested groups and set operands; disabled user rows still consume edit capacity but enforced rows are exempt. This example checks: Remaining filter capacity clamps over-limit imports to zero.

prompt:
Returning to a drilldown breadcrumb retains that breadcrumb itself is violated by the widget projection.

A facet drilldown trail records a sequence of scoped constraints; returning to a breadcrumb truncates later drilldowns while preserving independent global filters. This example checks: Returning to a drilldown breadcrumb retains that breadcrumb itself.

prompt:
Returning to drilldown root preserves independent global criteria is violated by the widget projection.

A facet drilldown trail records a sequence of scoped constraints; returning to a breadcrumb truncates later drilldowns while preserving independent global filters. This example checks: Returning to drilldown root preserves independent global criteria.
