- principalFrom sets PreferredLocale from metadata admin_locale; personal API token principals clear it, so token clients keep the request locale - the guarded admin group runs locale.from-principal after the backend guard, overriding the LocaleResolver or Accept-Language locale - GET /lang honours a supported ?locale= and reports meta.locales (cabana.LangEnvelope, cabana.LangMeta) - Docker test for the override, refusals and /lang; docs and OpenAPI
