Same-field user constraints do not overwrite enforced scope operands · case 05

Same-field user constraints do not overwrite enforced scope operands is violated by the widget projection.

Member previewVariant 5 · 3 implementations · 10 checks per implementation

Case contract

System-enforced filter constraints are immutable and survive user resets; user and system operands with the same field remain separate conjuncts. This example checks: Same-field user constraints do not overwrite enforced scope operands.

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.
