+- **Coverage** — `objectstack lint --i18n-strict` fails when a translatable key is missing from a
+  non-default locale, i.e. from `zh-CN`; `npx objectstack i18n check --show-keys` lists exactly which. It
+  cannot speak for `en`: it reports the source locale as 100 % translated, because the source label *is*
+  the translation.
+- **Source parity** — `pnpm check:i18n-source` ([`scripts/check-i18n-source.mjs`](./scripts/check-i18n-source.mjs))
+  compares every one of `en.ts`'s 507 keys against the label its metadata declares in the built artifact,
+  and fails on a drifted value, a key whose metadata is gone, or a source label `en.ts` never restates.
+  Renaming a label without renaming it in `en.ts` is a red gate, not a silent runtime override (#63).

+The Studio's own metadata-form strings are the platform's and are not this repository's to translate
