Saving restores stale initial values.

Member previewVariant 2 · 3 implementations · 9 checks per implementation

Case contract

Edits change draft only; reset restores baseline; commit accepts draft; unmount removal clears both; dirty comparison includes additions and removals.

Why this case matters

A deterministic model of form dirty-field bookkeeping; this isolates one interface invariant without requiring a browser.

One recorded failure
