Filter-chip identity and removal: Removing one chip removes equal values from other fields · case 02

Removing one chip removes equal values from other fields.

Member previewVariant 2 · 3 implementations · 9 checks per implementation

Case contract

Chip identity includes field and value; exclusive replacement clears only that field; removal targets one identity; field clear and global clear have distinct scope.

Why this case matters

A deterministic model of filter-chip identity and removal; this isolates one interface invariant without requiring a browser.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
