## Overview Internationalizes the **developer portal**, which previously had **zero i18n** — every string was hardcoded across ~118 components. Rather than stand up a parallel system, this shares the **editor's** existing i18n setup (same TOML locale format, same Crowdin pipeline), then converts every portal surface to `react-i18next` and adds a CI guard so coverage can't regress. ## What's included ### 🔗 Shared i18n core (`@shared/i18n`) - Extracts the editor's `TomlBackend` (HTTP loader for `public/locales/{lng}/translation.toml`) and language metadata/helpers (the 42-language list, RTL set, `LanguageSource` priority, code normalizers) into `frontend/shared/i18n/`. - The **editor** now imports and re-exports these from `@shared/i18n` — its 20+ consumers are unchanged. Its local `tomlBackend.ts` is deleted. - The **portal** builds its own i18next instance from the shared core, with **en-US as the source of truth** and the same `/locales/{lng}/translation.toml` layout. ### 🌍 Full portal coverage - Every view and component converted to `t()` — all feature areas (home, pipelines, sources, infrastructure, usage, documents, agent-builder, editor-admin, policies, users, docs, catalogue, components view) plus app shell, nav, modals, and the home/domain widgets. - **1108 keys across ~30 namespaces** in `portal/public/locales/en-US/translation.toml`, grouped by feature; shared strings under `[common]`. Plurals use i18next count forms; dynamic labels (nav, settings sections, status badges) use template keys against populated tables. - Data-driven strings (values from `@portal/api/*` mocks, enum/id values, code samples) are intentionally left untranslated — they're data, not UI chrome. ### ✅ CI coverage guard - `portal/scripts/check-i18n.mjs` fails if any static `t("key")` in portal source is missing from the en-US locale. Wired into `frontend:check` and `frontend:check:all`, so missed keys break CI. This mirrors the editor's `missingTranslations` test for the portal, which has no vitest harness of its own. ## Testing - `task frontend:check:all` passes locally (typecheck all variants, lint, format, **portal i18n guard**, builds, tests, storybook). - Every static `t()` key verified to resolve in the locale (1108 keys / 186 source files); all dynamic key prefixes map to populated tables. - Runtime sweep of all 12 portal routes shows **no unresolved keys** on screen; nav labels, plurals, and array-backed copy all render real text. ## Follow-ups (not in this PR) - **Crowdin** — register `frontend/portal/public/locales/` as a source so portal strings flow through the same translation pipeline as the editor (an ops step on the Crowdin side; there's no Crowdin config in the repo). - Only `en-US` is populated; other languages will arrive via the pipeline.
