## 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.
## Summary
Adds the **Policies** feature (proprietary, behind the
`POLICIES_ENABLED` flag): backend-driven enforcement that runs a fixed
tool pipeline on documents, docked in the right tool sidebar alongside
Tools.
## Highlights
- **Policy catalog** — 5 categories; **Security** is wired (redact PII +
sanitize), the others are marked "Coming soon".
- **Backend as source of truth** — policies persist via the Policies
engine (`/api/v1/policies`), one policy per category, with a local cache
+ offline fallback.
- **Auto-run** — enabled policies run on every uploaded file: dispatch →
poll → import outputs into the workspace.
- **Security redact config** — PII preset dropdown + custom word/regex
entry + advanced options; tool params map to the backend endpoint
fields.
- **Activity feed** with retry on failures; **file badges** showing
which policies ran on a file (sidebar + files page), tinted to the
policy colour.
- Reuses the **Watched Folders** engine for each policy's backing
folder; policy-owned folders are filtered out of the Watched Folders UI.
## Notes
- Gated by `POLICIES_ENABLED` (true in proprietary, false in core) —
unreachable in the open-source build.
- Frontend-only diff; depends on the backend Policies engine and the
merged Watched Folders feature.
# Description of Changes
## What & why
This PR introduces the **Stirling developer portal** — a new
control-plane frontend that sits alongside the existing PDF editor —
plus the shared design system and workspace structure needed to host
both apps in one frontend.
The portal is the parent product surface: where users connect sources,
compose pipelines, wire agents, and manage usage / billing /
infrastructure, with the PDF editor as one capability inside it. This PR
lays the **foundation** — workspace reshape, design system, app shell,
navigation, and a mock-driven home — rather than wiring real backends
(those surfaces are placeholders for follow-up phases).
## What's in this PR
**1. Frontend repo reshape (`frontend/src/` → `frontend/editor/`)**
The existing editor app moved under `frontend/editor/`, so `editor`,
`portal`, and `shared` are siblings in one workspace. All references
were updated accordingly: `LICENSE`, `.dockerignore`, `.gitignore`,
build/sign shell scripts, the GH language-check script, the Taskfile,
and Docker config. **No editor source logic changed — path references
only.**
**2. New shared design system (`frontend/shared/`)**
- **Design tokens** in `tokens.css` as the single runtime source of
truth (light/dark, category accents, gradients). `tokens.ts` now holds
only the `Tier` type — the old JS palette mirror was removed (nothing
consumed it and it had drifted).
- ~30 framework-light **components** (Card, Button, Input, Select, Tabs,
Modal, Drawer, Toast, MetricCard, StatusBadge, Skeleton, EmptyState, …)
with Storybook stories.
- **Typed data catalogues**: `endpoints.ts` (10 verticals / 64
endpoints) and `ops.ts`.
**3. New developer portal app (`frontend/portal/`)**
- App shell: `Header`, `Sidebar`, `AssistantPanel`, search modal,
notifications, tier switcher, theme toggle, MSW toggle.
- **Tier-aware** home (free / pay-as-you-go / enterprise): KPI strip,
30-day usage chart, onboarding checklist, quick actions, recent
activity, region health, product grid, and a curated **"Popular use
cases"** teaser.
- **Documents** view hosting the full, tab-filterable endpoint
catalogue.
- Placeholder views for Sources / Pipelines / Agents / Editor /
Infrastructure / Usage & Billing / Developer Docs / Settings (follow-up
phases).
- **MSW-mocked** API layer: `api/*` issues real `fetch`, intercepted by
mocks in dev/Storybook; pointing at a real backend is just a matter of
not registering MSW. `react-router` URLs; Tier / View / UI contexts.
**4. Tooling & guardrails**
- ESLint extended to `portal` + `shared`, with **layering-boundary
rules**: `shared/` may depend only on third-party packages and itself
(no `@app` / `@portal` / `@core` / `@proprietary` / Tauri), so it stays
cleanly extractable into a standalone package later.
- `dpdm` circular-dependency check now walks editor + portal + shared
(the old glob matched only 2 files).
- New **devDependencies only** — Storybook (+ a11y/docs/themes addons),
MSW. No runtime dependencies added.
- New tasks: `frontend:dev:portal`, `frontend:build:portal`.
## Testing done locally
- `tsc` for both `portal` and `shared` projects — clean
- `eslint --max-warnings=0` across the whole frontend — clean
- `dpdm` circular-dependency check — no cycles
- Editor builds clean: `vite build editor --mode core` (✓ built, only
the pre-existing >500 kB chunk-size advisory)
- Editor runs in dev (core mode) with **zero console errors**; portal
runs in dev across all three tiers
## Notes for reviewers
- The change is overwhelmingly **additive**: `shared/` and `portal/` are
brand-new; the existing editor is path-reference changes only.
- The portal is intentionally **mock-driven** at this stage — real
backends and the remaining views land in follow-up phases.
