Do not speculate about what code might be causing the issue.\n- Be brief and focused on collecting actionable information from the reporter.\n- If the issue already has everything needed (steps to reproduce, logs, version, OS), just acknowledge it.\n- Never exceed 15 lines.")

Review the actual diff, not just the description.\n- Do NOT nitpick formatting or style — the project has automated linting (biome + clippy + rustfmt).\n- Do NOT just summarize the PR description back to the user — they wrote it, they know what it says.\n- If the PR is good, say so briefly.\n- Never exceed 20 lines.")

-- After your changes, instead of running specific tests or linting specific files, run "pnpm format && pnpm lint && pnpm test". It means that you first format the code, then lint it, then test it, so that no part is broken after your changes.
-- Don't leave comments that don't add value.
-- Do not duplicate code unless you have a very good reason to do so. It is important that the same logic is not duplicated multiple times.
-- Before finishing the task and showing summary, always run "pnpm format && pnpm lint && pnpm test" at the root of the project to ensure that you don't finish with broken application.
-- Anytime you change nodecar's code and try to test, recompile it with "cd nodecar && pnpm build".
-- If there is a global singleton of a struct, only use it inside a method while properly initializing it, unless I have explicitly specified in the request otherwise.
-- If you are modifying the UI, do not add random colors that are not controlled by src/lib/themes.ts file.

+
+## Testing and Quality
+
+- After making changes, run `pnpm format && pnpm lint && pnpm test` at the root of the project
+- Always run this command before finishing a task to ensure the application isn't broken
+- `pnpm lint` includes spellcheck via [typos](https://github.com/crate-ci/typos). False positives can be allowlisted in `_typos.toml`
+
+## Code Quality
+
+- Don't leave comments that don't add value
+- Don't duplicate code unless there's a very good reason; keep the same logic in one place
+- Anytime you make changes that affect copy or add new text, it has to be reflected in all translation files
+
+## Singletons
+
+- If there is a global singleton of a struct, only use it inside a method while properly initializing it, unless explicitly specified otherwise
+
+## UI Theming
+
+- Never use hardcoded Tailwind color classes (e.g., `text-red-500`, `bg-green-600`, `border-yellow-400`). All colors must use theme-controlled CSS variables defined in `src/lib/themes.ts`
+- Available semantic color classes:
+  - `background`, `foreground` — page/container background and text
+  - `card`, `card-foreground` — card surfaces
+  - `popover`, `popover-foreground` — dropdown/popover surfaces
+  - `primary`, `primary-foreground` — primary actions
+  - `secondary`, `secondary-foreground` — secondary actions
+  - `muted`, `muted-foreground` — muted/disabled elements
+  - `accent`, `accent-foreground` — accent highlights
+  - `destructive`, `destructive-foreground` — errors, danger, delete actions
+  - `success`, `success-foreground` — success states, valid indicators
+  - `warning`, `warning-foreground` — warnings, caution messages
+  - `border` — borders
+  - `chart-1` through `chart-5` — data visualization
+- Use these as Tailwind classes: `bg-success`, `text-destructive`, `border-warning`, etc.
+- For lighter variants use opacity: `bg-destructive/10`, `bg-success/10`, `border-warning/50`
+
+## Publishing Linux Repositories
+
+The `scripts/publish-repo.sh` script publishes DEB and RPM packages to Cloudflare R2 (served at `repo.donutbrowser.com`). It requires Linux tools, so run it in Docker on macOS:
+
+```bash
+docker run --rm -v "$(pwd):/work" -w /work --env-file .env -e GH_TOKEN="$(gh auth token)" \
+  ubuntu:24.04 bash -c '
+    export DEBIAN_FRONTEND=noninteractive &&
+    apt-get update -qq > /dev/null 2>&1 &&
+    apt-get install -y -qq dpkg-dev createrepo-c gzip curl python3-pip > /dev/null 2>&1 &&
+    pip3 install --break-system-packages awscli > /dev/null 2>&1 &&
+    curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg 2>/dev/null &&
+    echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" > /etc/apt/sources.list.d/github-cli.list &&
+    apt-get update -qq > /dev/null 2>&1 && apt-get install -y -qq gh > /dev/null 2>&1 &&
+    bash scripts/publish-repo.sh v0.18.1'
+```
+
+The `.github/workflows/publish-repos.yml` workflow runs automatically after stable releases and can also be triggered manually via `gh workflow run publish-repos.yml -f tag=v0.18.1`.
+
+Required env vars / secrets: `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_ENDPOINT_URL`, `R2_BUCKET_NAME`.

-- Always run this command before finishing a task to ensure the application isn't broken
-
-## Code Quality
-
-- Don't leave comments that don't add value
-- Don't duplicate code unless there's a very good reason; keep the same logic in one place
-
-## Nodecar
-
-- After changing nodecar's code, recompile it with `cd nodecar && pnpm build` before testing
-
-## Singletons
-
-- If there is a global singleton of a struct, only use it inside a method while properly initializing it, unless explicitly specified otherwise
-
-## UI Theming
-
-- When modifying the UI, don't add random colors that are not controlled by `src/lib/themes.ts`

 ## Development Setup
 
-### Using Nix
-
-If you have [Nix](https://nixos.org/) installed, you can skip the manual setup below and simply run:
+### Using Nix (recommended)
 
 ```bash
-nix develop
-# or if you use direnv
-direnv allow
+nix run .#setup     # Install dependencies
+nix run .#tauri-dev  # Start development server
+nix run .#test       # Run all checks
 ```
 
-This will provide Node.js, Rust, and all necessary system libraries.
+Or enter the dev shell: `nix develop`
 
 ### Manual Setup
 
-Ensure you have the following dependencies installed:
+Requirements:
 
-- Node.js (see `.node-version` for exact version)
-- pnpm package manager
-- Latest Rust and Cargo toolchain
-- [Tauri prerequisites guide](https://v2.tauri.app/start/prerequisites/).
-
-## Run Locally
-
-After having the above dependencies installed, proceed through the following steps to setup the codebase locally:
-
-1. **Fork the project** & [clone](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository) it locally.
-
-2. **Create a new separate branch.**
-
-   ```bash
-   git checkout -b feature/my-feature-name
-   ```
-
-3. **Install frontend dependencies**
-
-   ```bash
-   pnpm install
-   ```
-
-4. **Start the development server**
-
-   ```bash
-   pnpm tauri dev
-   ```
-
-This will start the app for local development with live reloading.
-
-## Code Style & Quality
-
-We use several tools to maintain code quality:
-
-- **Biome** for JavaScript/TypeScript linting and formatting
-- **Clippy** for Rust linting
-- **rustfmt** for Rust formatting
-
-### Before Committing
-
-Run these commands to ensure your code meets our standards:
+- Node.js (see `.node-version`)
+- pnpm
+- Rust + Cargo (latest stable)
+- [Tauri v2 prerequisites](https://v2.tauri.app/start/prerequisites/)
 
 ```bash
-# Format and lint frontend code
-pnpm format:js
-
-# Format and lint Rust code
-pnpm format:rust
-
-# Run all linting
-pnpm lint
+git checkout -b feature/my-feature-name
+pnpm install
+pnpm tauri dev
 ```
 
-## Building
+## Quality Checks
 
-It is crucial to test your code before submitting a pull request. Please ensure that you can make a complete production build before you submit your code for merging.
+Run before every commit:
 
 ```bash
-# Build the frontend
-pnpm build
-
-# Build the backend
-cd src-tauri && cargo build
-
-# Build the Tauri application
-pnpm tauri build
+pnpm format && pnpm lint && pnpm test
 ```
 
-Make sure the build completes successfully without errors.
+This runs:
 
-## Testing
+- **Biome** — JS/TS linting and formatting
+- **Clippy + rustfmt** — Rust linting and formatting
+- **typos** — Spellcheck (allowlist in `_typos.toml`)
+- **CodeQL** — Security analysis (JS, Actions, Rust) — runs in CI
+- **Unit tests** — 330+ Rust tests
+- **Integration tests** — proxy, sync e2e
 
-- Always test your changes on the target platform
-- Verify that existing functionality still works
-- Add tests for new features when possible
+### Running CodeQL locally
+
+```bash
+# Install: brew install codeql
+codeql pack download codeql/javascript-queries codeql/rust-queries
+
+# JavaScript
+codeql database create /tmp/codeql-js --language=javascript --source-root=.
+codeql database analyze /tmp/codeql-js --format=sarifv2.1.0 --output=/tmp/js.sarif codeql/javascript-queries
+
+# Rust
+codeql database create /tmp/codeql-rust --language=rust --source-root=.
+codeql database analyze /tmp/codeql-rust --format=sarifv2.1.0 --output=/tmp/rust.sarif codeql/rust-queries
+```
+
+## Key Rules
+
+- **Translations**: Any UI text changes must be reflected in all 7 locale files (`src/i18n/locales/`)
+- **Tauri commands**: If you modify Tauri commands, the `test_no_unused_tauri_commands` test will catch unused ones
+- **No hardcoded colors**: Use theme CSS variables (see `src/lib/themes.ts`), never Tailwind color classes like `text-red-500`
+- **No lock file changes**: Don't update `pnpm-lock.yaml` or `Cargo.lock` unless updating dependencies is the purpose of the PR
+- **AGPL-3.0**: This project is AGPL-licensed. Derivatives must be open source with the same license
 
 ## Pull Request Guidelines
 
-🎉 Now that you're ready to submit your code for merging, there are some points to keep in mind:
+- Fill the PR description template
+- Reference related issues (`Fixes #123` or `Refs #123`)
+- Include screenshots/videos for UI changes
+- Ensure "Allow edits from maintainers" is checked
 
-### PR Description
+## Architecture
 
-- Fill your PR description template accordingly
-- Have an appropriate title and description
-- Include relevant screenshots for UI changes. If you can include video/gifs, it is even better.
-- Reference related issues
-

-
-```text
-Fixes #00000
-```
-
-If your PR is referencing an issue:

+
+If the AppImage segfaults on launch, install **libfuse2** (`sudo apt install libfuse2` / `yay -S libfuse2` / `sudo dnf install fuse-libs`), or bypass FUSE entirely:
+
+```bash
+APPIMAGE_EXTRACT_AND_RUN=1 ./Donut.Browser_x.x.x_amd64.AppImage
+```
+
+If that gives an EGL display error, try adding `WEBKIT_DISABLE_DMABUF_RENDERER=1` or `GDK_BACKEND=x11` to the command above. If issues persist, the **.deb** / **.rpm** packages are a more reliable alternative.

+# 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;
+    }
+}
+```
