Reuse the named domain locales field instead of reconstructing an optional
array from its element type. Preserve min/max selection bounds through the
CLI parser and public JSON Schema while retaining the repeat-flag guidance.
The application service already validates the input; provider authority is
unchanged.
Add a public schema regression and compare advertised Ajv2020 acceptance
and CLI parser acceptance with the owner for omission, empty, valid,
maximum, oversized and invalid-element selections.
Validation: regression fails unchanged d37c34647; 21 focused checks across
4 files, check:fast and docs:check pass. Source review found no blocker.
No real-provider or performance qualification claim. Heavy tests remain
stopped.
