+
+**NEVER run any git command that modifies git history OR the working tree, in ANY repo** (wayfern, wayfern-macos, wayfern-test, donutbrowser, build/src), **unless the user EXPLICITLY authorizes that exact command.** Forbidden without per-command authorization: `commit`, `revert`, `cherry-pick`, `restore`, `checkout` (files/branches), `reset`, `rebase`, `merge`, `stash`, `clean`, `apply`, `add`, `rm`, `push`, any force op. Only read-only git (`status`, `log`, `show`, `diff`, `ls-files`, `rev-parse`) is allowed without asking. **Authorization is per-command: 1 explicit authorization = exactly 1 command.** If a git mutation seems needed, STOP and ask for that one command.

 Three log surfaces, in order of usefulness:
 
-- **Donut Browser GUI** — `~/Library/Logs/com.donutbrowser/DonutBrowser.log` on macOS (newest = active session; older `DonutBrowser_<date>.log` are rotated). The GUI / Tauri / `browser_runner` / `proxy_manager` / `sync` all log here. Search for `Camoufox`, `Wayfern`, `Starting local proxy`, `Configured local proxy` to find a launch chain.

 - **donut-proxy worker** — `$TMPDIR/donut-proxy-<config_id>.log`. One file per proxy worker process (each profile launch spawns a fresh one). Map a worker to its launch via the `Cleanup: browser PID X is dead, stopping proxy worker <id>` lines in DonutBrowser.log, or by mtime. CONNECT requests, upstream accept/reject (status lines like `HTTP/1.1 402 user reached limit`), and tunnel errors are at INFO/WARN — anything finer is at TRACE and requires `RUST_LOG=donut_proxy=trace`. The `Upstream CONNECT response coalesced N byte(s) of payload — these would be dropped without forwarding` warning marks a real bug in `handle_connect_from_buffer` if it ever fires.
-- **Camoufox stderr** — `$TMPDIR/camoufox-stderr-<profile_id>.log`, written by `camoufox_manager::launch_camoufox`. Captures NSS / GPU Helper / juggler errors. Firefox does **not** print TLS/network errors here by default — set `MOZ_LOG=nsHttp:5,signaling:5` on the env if you need that. The `RustSearch.sys.mjs missing field 'recordType'` lines are noise from our `search.json.mozlz4` schema being slightly off for FF150+; not a network problem.

 - 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 seven locale files in `src/i18n/locales/` (en, es, fr, ja, pt, ru, zh) — not just `en.json`. The English version alone is incomplete work.
+- 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.
 - 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 seven locales, use a one-shot Python script in `/tmp/` that loads each `*.json`, mutates it, and writes it back. Seven sequential `Edit` calls drift (typos, ordering differences) and burn tokens; a single script keeps the locales in lockstep and is easy to throw away.

 Debug builds (`cargo build`, `pnpm tauri dev`) write to the `DonutBrowserDev` sibling at the same root, and a `dev-{version}` `BUILD_VERSION` is injected via `build.rs`.

-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;
-    }
-}
-```

-//! Camoufox browser integration module.
-//!
-//! Provides native Rust support for launching Camoufox browsers with realistic
-//! fingerprint injection using playwright-rust.
-//!
-//! # Overview
-//!
-//! This module replaces the previous Node.js-based nodecar implementation with
-//! a pure Rust solution. Key components:
-//!
-//! - **Fingerprint Generation**: Bayesian network-based fingerprint generation
-//! - **WebGL Sampling**: Realistic WebGL configurations from a SQLite database
-//! - **Configuration Builder**: Converts fingerprints to Camoufox config format
-//! - **Launcher**: playwright-rust integration for browser launching
-//!
-//! # Example
-//!
-//! ```rust,ignore
-//! use donutbrowser_lib::camoufox::{CamoufoxLauncher, LaunchOptions};
-//!
-//! async fn launch_browser() -> Result<(), Box<dyn std::error::Error>> {
-//!     let launcher = CamoufoxLauncher::new("/path/to/camoufox").await?;
-//!
-//!     let options = LaunchOptions {
-//!         os: Some("windows".to_string()),
-//!         headless: false,
-//!         ..Default::default()
-//!     };
-//!
-//!     let browser = launcher.launch(options).await?;
-//!
-//!     // Use the browser...
-//!
-//!     browser.close().await?;

-//! Real-fingerprint preset support for Camoufox.
-//!
-//! Mirrors the preset-selection logic from
-//! `pythonlib/camoufox/fingerprints.py` (`_select_presets_file`,
-//! `load_presets`, `get_random_preset`, `from_preset`).
-//!
-//! Camoufox ships two bundled preset files:
-//! - `fingerprint-presets-v135.json` — real fingerprints harvested from
-//!   browsers running Firefox ≤148. The frozen "v135 line" — kept around
-//!   so users who haven't upgraded their Camoufox binary keep getting
-//!   consistent fingerprints.
-//! - `fingerprint-presets-v150.json` — the *newer* bundle, refreshed by
-//!   upstream as Camoufox tracks newer Firefox versions. This is the
-//!   bundle every newer Camoufox release uses; we make no assumption that
-//!   Firefox 150 is the ceiling.
-//!
-//! At launch we know the bundled Firefox version (see
-//! `config::get_firefox_version`) and pick `v135` or `newer` accordingly.
-//! The split point lives in `data::PRESETS_NEWER_MIN_FF` (currently 149)
-//! and is the only number we hard-code — anything ≥ that gets the newer
-//! bundle, regardless of how far Firefox itself has moved on.
-//!
-//! Falling back to Bayesian-network synthesis (the previous default) is
-//! still possible when no preset matches the requested OS.

+//! Local SOCKS5 server served to the browser (Wayfern/Chromium).
+//!
+//! The HTTP front-end (`proxy_server::handle_proxy_connection`) can only tunnel
+//! TCP, so QUIC and WebRTC — which are UDP — would be forced direct and leak the
+//! real IP. Serving SOCKS5 instead lets Chromium proxy UDP via SOCKS5 UDP
+//! ASSOCIATE (RFC 1928). TCP CONNECT reuses the exact same upstream-dial and
+//! tunnel code as the HTTP path, so every upstream type (direct, HTTP/HTTPS
+//! CONNECT, SOCKS4/5, Shadowsocks) behaves identically.
+//!
+//! UDP ASSOCIATE is leak-safe by construction: UDP is only relayed where it
+//! cannot expose the host IP — directly when there is no upstream proxy, or
+//! tunneled through a UDP-capable SOCKS5 upstream. For upstreams that cannot
+//! carry UDP (HTTP/HTTPS/SOCKS4/Shadowsocks, or a SOCKS5 upstream that refuses
+//! the association) the request is refused, so Chromium falls back to proxied
+//! TCP rather than sending UDP from the real IP.
