prompt:
Typed bounds convert from selected units to canonical storage is violated by the widget projection.

The filter stores canonical integer base units while the editor shows exact scaled integers; a unit switch changes presentation without changing the committed quantity. This example checks: Typed bounds convert from selected units to canonical storage.

The filter stores canonical integer base units while the editor shows exact scaled integers; a unit switch changes presentation without changing the committed quantity. This example checks: A nonintegral display bound is marked instead of silently truncated.
