# i18n Tooling

The i18n pipeline is summarized in [build.md](build.md). This page captures the app-facing rules.

## App Names

`manifest.displayNameEn` is automatically patched into the OS English string table. New apps should not edit `os/i18n/en.ts` just to add their launcher name.

## App Strings

App UI strings belong in `apps/<App>/res/strings.ts` and, when present, localized companion files such as `strings.en.ts`.

Keep IDs semantic and stable; do not store translated display strings as state when a semantic enum would be better.
