# X_CATALOG_UNREGISTERED

## Means

a shipped catalog never reached the runtime registry

## Typical cause

`defineCatalogs()` in a module the boot scan never imports, or one that throws on import — every string renders `⟦key⟧` while `x verify` is green. When two copies of `@ultimat3/i18n` are installed the cause says so instead, and the fix is the install's (`X_PACKAGE_DUPLICATED`, reported beside it): the call is where it should be and registered into the copy the CLI does not read

## Fix

move the `defineCatalogs()` call into `packages/i18n/src/index.ts` and read strings through its `useT()`; `x i18n check --json` re-checks
