### PR Review Process

- PRs require at least one approving review
- CI checks must pass
- PRs should be up to date with `main` before merging

## Coding Standards

### Rust

- Follow the [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/)
- Use `rustfmt` for formatting
- Address all `clippy` warnings
- Write documentation for public APIs
- Include unit tests for new functionality

```rust
// Good: Documented public function with error handling
/// Sends a Wake-on-LAN magic packet to the specified MAC address.
///
/// # Arguments
///
/// * `mac` - The MAC address of the target device
/// * `broadcast` - Optional broadcast address (defaults to 255.255.255.255)
///
/// # Errors
///
/// Returns an error if the magic packet cannot be sent.
pub fn wake_device(mac: &MacAddress, broadcast: Option<IpAddr>) -> Result<(), WolError> {
    // Implementation
}
```

### TypeScript/React (Web UI)

- Use TypeScript strict mode
- Follow ESLint and Prettier configuration
- Use functional components with hooks
- Keep components small and focused

```typescript
// Good: Typed component with proper props interface
interface DeviceCardProps {
  device: Device;
  onWake: (id: string) => Promise<void>;
}

export function DeviceCard({ device, onWake }: DeviceCardProps) {
  // Implementation
}
```

## Commit Messages
