 - The full `pnpm test` output dumps every test name (≈400+ lines) which burns context for no signal. Filter:
  `pnpm test 2>&1 | grep -E "test result|panicked|FAILED"` — four "test result: ok" lines means everything passed.

+### Native app E2E tests are mandatory for affected behavior
+
+The native suites use a sibling private test-driver repository and launch an `e2e`-feature build.
+Every session gets its own temporary Donut data/cache/log root, home directory,
+WebView store, ports, and sync bucket. Never point a suite at production or development data.
+
+After a behavior change, run the smallest affected subset below in addition to the standard
+format/lint/unit-test command. A code change is not considered verified until its affected native
+suite passes:
+
+| Changed area | Required command |
+| --- | --- |
+| Startup, settings, persistence, window state, shortcuts, navigation | `pnpm e2e:smoke` |
+| React components, dialogs, themes/appearance, responsive layout, accessibility, onboarding | `pnpm e2e:ui` |
+| Profile/import/group/proxy/VPN/extension CRUD, DNS, cookies, passwords, traffic | `pnpm e2e:entities` |
+| Profile/group/proxy/VPN/extension UI, proxy routing, VPN routing, or their browser-launch integration | `pnpm e2e:network` |
+| REST API/OpenAPI, MCP, cloud/update contracts, team locks, real-time synchronizer | `pnpm e2e:integrations` |
+| Sync client/server, manifests, timestamps, deletion, encryption, password rollover | `pnpm e2e:sync` |
+| Wayfern download/terms/fingerprint, browser runner, CDP, automation endpoints, process cleanup | `pnpm e2e:browser` |
+| E2E harness, WebDriver plugin/driver, app isolation hooks, or changes spanning multiple rows | Run every affected row; use `pnpm e2e` for cross-cutting changes |
+
+`e2e:browser` requires `WAYFERN_TEST_TOKEN` in the environment or local `.env`. `e2e:network`
+and the full suite additionally require Docker plus `RESIDENTIAL_PROXY_URL_ONE_HTTP` and
+`RESIDENTIAL_PROXY_URL_ONE_SOCKS`. Other individual suites must run without credentials. Use
+`--no-build` only when the frontend, Rust app, sidecar, and WebDriver binaries are already current.
+Keep failed artifacts and inspect the per-session app/driver logs and screenshot before changing
+assertions.
+
+When adding a Tauri command, assign it exactly once in `e2e/coverage-map.mjs` and add executable
+evidence to the owning suite. `e2e:smoke` fails if command registration and the coverage map drift.

 - Never write user-facing strings as raw English literals in JSX, toast messages, dialog titles/descriptions, button labels, placeholders, table headers, tooltips, or empty-state text. Always go through `t("namespace.key")` from `useTranslation()`.
 - This applies to every component under `src/` — including new ones. If a component doesn't already import `useTranslation`, add it.
- Adding a new string means adding the key to ALL nine locale files in `src/i18n/locales/` (en, es, fr, ja, ko, pt, ru, vi, zh) — not just `en.json`. The English version alone is incomplete work.
+- Adding a new string means adding the key to EVERY locale file in `src/i18n/locales/` — currently en, es, fr, ja, ko, pt, ru, tr, vi, zh — not just `en.json`. The English version alone is incomplete work. Don't trust this list: enumerate `src/i18n/locales/*.json` and update every file you find, because a newly added locale is exactly what a hardcoded list silently skips.
 - Reuse existing keys (`common.buttons.*`, `common.labels.*`, `createProfile.*`, etc.) before creating new namespaces. Check `en.json` first.
 - Strings excluded from this rule: `console.log/warn/error`, dev-only debug labels, internal IDs, CSS class names, type names. If unsure whether a string renders to the user, assume it does and translate it.
 - **Never use `t(key, "fallback")` with a default-value second argument.** The 2-arg form is forbidden — every key must exist in every locale file before the call site lands. Fallbacks mask missing translations: a key missing from `ru.json` will silently render the English fallback to Russian users, so the bug never surfaces in CI or review. Only call `t("namespace.key")`. If a translation is missing for any locale, that's a bug to fix at the JSON, not a hole to paper over at the call site.
 - Empty-string values in non-English locales are also forbidden — a locale either has the right translation or it has the same content as English; never `""`. If a particular language doesn't need a particular phrase (e.g. a suffix that doesn't grammatically apply), refactor the JSX to use a single interpolated key (`t("foo.bar", { name })` with `"...{{name}}..."` in each locale) instead of splitting prefix/suffix.
- When adding or removing keys across all nine locales, use a one-shot Python script in `/tmp/` that loads each `*.json`, mutates it, and writes it back. Nine sequential `Edit` calls drift (typos, ordering differences) and burn tokens; a single script keeps the locales in lockstep and is easy to throw away.
+- When adding or removing keys across the locales, use a one-shot Python script in the scratchpad dir that globs `src/i18n/locales/*.json`, mutates each, and writes it back. Sequential `Edit` calls drift (typos, ordering differences) and burn tokens; a single script keeps the locales in lockstep and is easy to throw away. Finish by diffing every locale's flattened key set against `en.json` — zero missing and zero extra, for all of them.

 Raw error strings reach the user untranslated; that's the bug pattern this rule blocks.

+## REST API (`src-tauri/src/api_server.rs`) — endpoints must stay in the OpenAPI spec
+
+The served `/openapi.json` comes from the hand-maintained `ApiDoc` derive (`#[derive(OpenApi)]` with `paths(...)`, `components(schemas(...))`, `tags(...)`) — NOT from the router. The `OpenApiRouter`-generated spec is discarded (`let (v1_routes, _) = ...`), so a handler registered on the router but missing from `ApiDoc` silently disappears from the spec (this happened to the extension and VPN-export endpoints once).
+
+**Any endpoint modification — adding, removing, or changing a route, request/response schema, or status code — must be reflected in the OpenAPI spec in the same change:**
+
+1. Keep the handler's `#[utoipa::path]` annotation accurate (path, request body, every reachable response status).
+2. Add/remove the handler in `ApiDoc`'s `paths(...)` list and any new schema types in `components(schemas(...))`.
+3. Extend the `openapi_*` regression tests in `api_server.rs::tests` (they assert spec coverage and that optional fields stay optional).
+4. `#[schema(value_type = Object)]` on an `Option<T>` field erases the optionality and wrongly marks it required — use `value_type = Option<Object>` (or drop the attribute for natively supported types).
+
+### Error status conventions (known errors)
+
+Handlers route manager errors through `manager_error_response`, which maps message content onto a consistent status and passes the text through as the response body:
+
+- `401` — missing/invalid bearer token (auth middleware; empty body).
+- `402` — the five automation endpoints (`run`, `open-url`, `kill`, `batch/run`, `batch/stop`) without a paid plan, and expired-proxy (`PROXY_PAYMENT_REQUIRED`) checks.
+- `404` — entity not found (`… not found` / `*_NOT_FOUND`).
+- `400` — validation, duplicates, empty names, invalid/unsupported/unavailable input.
+- `409` — conflicts: browser version already being downloaded, profile locked by another team member (run), browser running during cookie import.
+- `500` — internal failures (IO, network, poisoned locks).
+
+Error bodies are plain-text diagnostics; some are the JSON `{"code": ...}` strings shared with the Tauri commands (e.g. `NAME_CANNOT_BE_EMPTY`, `GROUP_ALREADY_EXISTS`). The translated-error rule above applies to Tauri commands, not to REST bodies.

-# Self-Hosting Donut Sync
-
-Donut Sync is the synchronization server for Donut Browser. It allows you to sync your profiles, proxies, and groups across multiple devices. This guide covers how to self-host it using Docker.
-
-## Prerequisites
-
- [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/)
- An S3-compatible object storage (MinIO included by default, or use AWS S3, Cloudflare R2, etc.)
-
-## Quick Start
-
-### 1. Create a `docker-compose.yml`
-
-```yaml
-services:
-  donut-sync:
-    image: donutbrowser/donut-sync:latest
-    ports:
-      - "3929:3929"
-    environment:
-      - SYNC_TOKEN=your-secret-token-here
-      - PORT=3929
-      - S3_ENDPOINT=http://minio:9000
-      - S3_REGION=us-east-1
-      - S3_ACCESS_KEY_ID=minioadmin
-      - S3_SECRET_ACCESS_KEY=minioadmin
-      - S3_BUCKET=donut-sync
-      - S3_FORCE_PATH_STYLE=true
-    depends_on:
-      minio:
-        condition: service_healthy
-
-  minio:
-    image: minio/minio:latest
-    ports:
-      - "9000:9000"
-      - "9001:9001"
-    environment:
-      MINIO_ROOT_USER: minioadmin
-      MINIO_ROOT_PASSWORD: minioadmin
-    command: server /data --console-address ":9001"
-    healthcheck:
-      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
-      interval: 5s
-      timeout: 5s
-      retries: 5
-    volumes:
-      - minio_data:/data
-
-volumes:
-  minio_data:
-```
-
-### 2. Start the services
-
-```bash
-docker compose up -d
-```
-
-### 3. Verify the server is running
-
-```bash
-# Health check
-curl http://localhost:3929/health
-# Expected: {"status":"ok"}
-
-# Readiness check (verifies S3 connectivity)
-curl http://localhost:3929/readyz
-# Expected: {"status":"ready","s3":true}
-```
-
-## Environment Variables
-
-| Variable | Required | Default | Description |
-|---|---|---|---|
-| `SYNC_TOKEN` | Yes | - | Bearer token used to authenticate requests from Donut Browser clients |
-| `PORT` | No | `3929` | Port the sync server listens on |
-| `S3_ENDPOINT` | No | - | S3-compatible endpoint URL (e.g., `http://minio:9000` or `https://s3.amazonaws.com`) |
-| `S3_REGION` | No | `us-east-1` | S3 region |
-| `S3_ACCESS_KEY_ID` | Yes | - | S3 access key |
-| `S3_SECRET_ACCESS_KEY` | Yes | - | S3 secret key |
-| `S3_BUCKET` | No | `donut-sync` | S3 bucket name for storing sync data |
-| `S3_FORCE_PATH_STYLE` | No | `false` | Set to `true` for MinIO and other S3-compatible services that use path-style URLs |
-
-## Using External S3 Storage
-
-Instead of running MinIO, you can use any S3-compatible storage service. Remove the `minio` service from `docker-compose.yml` and update the environment variables:
-
-### AWS S3
-
-```yaml
-services:
-  donut-sync:
-    image: donutbrowser/donut-sync:latest
-    ports:
-      - "3929:3929"
-    environment:
-      - SYNC_TOKEN=your-secret-token-here
-      - S3_REGION=us-east-1
-      - S3_ACCESS_KEY_ID=your-aws-access-key
-      - S3_SECRET_ACCESS_KEY=your-aws-secret-key
-      - S3_BUCKET=your-bucket-name
-```
-
-### Cloudflare R2
-
-```yaml
-services:
-  donut-sync:
-    image: donutbrowser/donut-sync:latest
-    ports:
-      - "3929:3929"
-    environment:
-      - SYNC_TOKEN=your-secret-token-here
-      - S3_ENDPOINT=https://<account-id>.r2.cloudflarestorage.com
-      - S3_REGION=auto
-      - S3_ACCESS_KEY_ID=your-r2-access-key
-      - S3_SECRET_ACCESS_KEY=your-r2-secret-key
-      - S3_BUCKET=your-bucket-name
-      - S3_FORCE_PATH_STYLE=true
-```
-
-### Other S3-Compatible Services
-
-Any service that implements the S3 API (e.g., Backblaze B2, DigitalOcean Spaces, Wasabi) can be used. Set `S3_ENDPOINT` to the service's endpoint URL and `S3_FORCE_PATH_STYLE=true` if required by the provider.
-
-## Configuring the Donut Browser Client
-
-1. Open Donut Browser
-2. Click the sync icon in the header to open the Sync Configuration dialog
-3. Enter the **Server URL** (e.g., `http://your-server:3929`)
-4. Enter the **Sync Token** (the value you set for `SYNC_TOKEN`)
-5. Click **Save**
-
-Once configured, you can enable sync on individual profiles, proxies, and groups.
-
-## Health Check Endpoints
-
-| Endpoint | Description |
-|---|---|
-| `GET /health` | Basic health check. Returns `{"status":"ok"}` if the server is running. |
-| `GET /readyz` | Readiness check. Verifies S3 connectivity. Returns `{"status":"ready","s3":true}` or HTTP 503 if S3 is unreachable. |
-
-## Security Considerations
-
- **Use a strong `SYNC_TOKEN`**: Generate a random token (e.g., `openssl rand -hex 32`) and keep it secret.
- **HTTPS**: In production, place a reverse proxy (e.g., Nginx, Caddy, Traefik) in front of Donut Sync to terminate TLS. The sync token is sent as a Bearer token in the `Authorization` header and should not be transmitted over plain HTTP.
- **Network isolation**: If running on a VPS, consider restricting access to the sync port using firewall rules or binding only to localhost behind a reverse proxy.
- **S3 credentials**: Use dedicated IAM credentials with minimal permissions (read/write to the sync bucket only).
-
-### Example: Caddy Reverse Proxy
-
-```
-sync.yourdomain.com {
-    reverse_proxy localhost:3929
-}
-```
-
-### Example: Nginx Reverse Proxy
-
-```nginx
-server {
-    listen 443 ssl;
-    server_name sync.yourdomain.com;
-
-    ssl_certificate /path/to/cert.pem;
-    ssl_certificate_key /path/to/key.pem;
-
-    location / {
-        proxy_pass http://localhost:3929;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }

+# Donut Browser native E2E tests
+
+These tests exercise the actual Tauri application through a sibling native test driver. They do
+not replace Rust or React unit tests; they
+cover the process boundaries those tests cannot: WKWebView/WebView2/WebKitGTK UI, Tauri invokes,
+REST and MCP servers, two-device sync, S3 payload encryption, Wayfern, CDP, and child-process
+cleanup.
+
+## Local setup
+
+Place both repositories beside each other:
+
+```text
+Code/
+├── donutbrowser/
+└── <test-driver-checkout>/
+```
+
+Install Donut dependencies with `pnpm install`. The browser suite also needs
+`WAYFERN_TEST_TOKEN`. The runner reads it from the environment or Donut's ignored `.env` without
+printing it. When a local browser fixture is configured, the runner copies it into the test data
+root (using an isolated APFS clone on macOS); otherwise the browser suite downloads the current
+published build into that root.
+
+Set `DONUT_E2E_WAYFERN_PATH` to use a local browser fixture. Without it, the runner uses an ignored
+cache fixture when present and otherwise downloads the published test build.
+
+The real-network suite additionally requires Docker plus
+`RESIDENTIAL_PROXY_URL_ONE_HTTP` and `RESIDENTIAL_PROXY_URL_ONE_SOCKS`. It creates its own
+WireGuard server and tunnel-only HTTP target in a disposable container. It never connects a test
+profile to a developer or production VPN.
+
+Run one suite:
+
+```sh
+pnpm e2e:smoke
+pnpm e2e:ui
+pnpm e2e:entities
+pnpm e2e:network
+pnpm e2e:integrations
+pnpm e2e:sync
+pnpm e2e:browser
+```
+
+Run everything with `pnpm e2e`. A normal run builds the Next frontend, `donut-proxy`, the
+private harness in `e2e/app`, and `tauri-wd`. The harness enables Donut's `e2e` feature and injects
+the sibling WebDriver plugin without making the production crate depend on a private filesystem
+path. Add `--no-build` to `node e2e/run.mjs --suite=<name>` only when all four outputs are current.
+`DONUT_E2E_KEEP_ARTIFACTS=1` retains successful local runs; failed runs are always retained and
+their location is printed. Raw screenshots, captured HTML, logs, and isolated app state stay local.
+The runner also creates a text-only `diagnostics/` directory whose logs are redacted and checked
+against active test secrets. CI uploads only that directory on failure. Disposable copied browser
+binaries are pruned so repeated failures do not consume gigabytes.
+
+The suites deliberately distinguish visible behavior from command coverage. `e2e:entities`
+exercises isolated CRUD and persistence through Tauri commands. `e2e:network` visibly creates a
+profile group, HTTP proxy, WireGuard VPN, extension, extension group, and Wayfern profile; assigns
+the proxy and VPN in the profile table; validates both residential HTTP and SOCKS5 proxies; then
+launches Wayfern through the residential proxy and through the local WireGuard tunnel. Normal test
+sessions start with onboarding completed so the Welcome dialog cannot hide the feature under test.
+The onboarding and Wayfern-terms scenarios explicitly opt into fresh state and test those dialogs.
+`e2e:ui` selects predefined, preset, and manually customized themes through the native UI and
+asserts their persisted settings and rendered CSS variables across rail navigation and app restart.
+
+## Isolation contract
+
+Each app session receives a unique root under the operating-system test temp directory. The
+runner redirects:
+
+- Donut data, cache, and logs with `DONUTBROWSER_DATA_ROOT`;
+- `HOME`, `USERPROFILE`, `CFFIXED_USER_HOME`, XDG paths, `APPDATA`, and `LOCALAPPDATA`;
+- `TMPDIR`, `TMP`, and `TEMP`;
+- the Tauri WebView store (incognito for WKWebView, whose persistent data-directory API is not
+  honored);
+- all REST, MCP, WebDriver, fixture, MinIO, and sync-server ports;
+- each sync test to a new MinIO bucket and random token.
+
+The E2E feature suppresses automatic updater/download traffic, but explicit browser tests still
+exercise published Wayfern downloads when no local fixture exists. Entitlement fallback from
+`WAYFERN_TEST_TOKEN` exists only in the feature-gated test binary. Production builds never include
+the WebDriver plugin or this fallback.
+
+## CI
+
+`.github/workflows/app-e2e.yml` runs smoke tests on macOS, Linux/Xvfb, and Windows for pull
+requests. Pushes to `main`, weekly schedules, and manual runs execute the full macOS suite,
+including MinIO-backed sync and real Wayfern automation, plus a Linux/Docker job for residential
+proxy and local WireGuard browser traffic.
+
+CI needs a `TAURI_WEBDRIVER_TOKEN` secret with read-only access and a
+`TAURI_WEBDRIVER_REPOSITORY` repository variable identifying the test-driver checkout. The full
+job also requires the `WAYFERN_TEST_TOKEN` secret. The network job requires that secret plus
+`RESIDENTIAL_PROXY_URL_ONE_HTTP` and `RESIDENTIAL_PROXY_URL_ONE_SOCKS`.
