no values are skipped

Error message

no values are skipped

What it means

Assertion in the Display implementation test path for InternalPackageMode: formatting every clap value variant must succeed and emit each variant without skipping any (embedded, force-write, read-from-disk). Fires only if a new variant is added without Display coverage or formatting regresses.

Solutions

1. Add a Display arm / clap value for any newly added InternalPackageMode variant
2. Keep the variant list and the formatting test in sync
3. Treat failure as a test coverage gap for enum display
