test(integration): pin #285 rename PUT behaviour at the HTTP layer

Adds rename_device.http between get_group.http and unregister_device.http
in the make test-http-client sequence. The new test fires the PUT
the speaker emits after a rename and asserts:

  - 200 OK, content type vnd.bose.streaming-v1.2+xml
  - the response carries the renamed value
  - createdOn matches the value captured during register_device.http
    (cross-request global), locking in the "first-paired" semantics
  - ipaddress is preserved from the prior power_on, not reset by the
    rename body's empty IP field
  - a mismatched body deviceid is rejected with 400

register_device.http captures the initial createdOn into a global so
the rename test can assert equality rather than a flakier
updatedOn != createdOn heuristic. The variant POST's stale
updatedOn === createdOn assertion is replaced with an upsert-aware
equality against the same captured global.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+tobias@gesellix.de.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

+   - Any breaking changes
+3. **Link to related issues**
+4. **Update CHANGELOG.md** if applicable
+5. **Ensure CI passes**
+
+### Review Process
+
+- At least one maintainer will review your PR
+- Feedback will be constructive and specific
+- Address feedback in additional commits
+- Once approved, a maintainer will merge your PR
+
+## Coding Guidelines
+
+### Go Style
+
+Follow standard Go conventions:
+
+- **gofmt** for formatting
+- **golangci-lint** for comprehensive code quality checks
+- **go vet** for static analysis
+- **Effective Go** principles
+- **Standard library patterns** where applicable
+
+### Code Organization
+
+```go
+// Package-level documentation
+package client
+
+import (
+    // Standard library first
+    "context"
+    "encoding/xml"
+    
+    // Third-party packages
+    "github.com/gorilla/websocket"
+    
+    // Local packages
+    "github.com/gesellix/bose-soundtouch/pkg/models"
+)
+
+// Public API should be well-documented
+// GetDeviceInfo retrieves comprehensive device information including
+// model, capabilities, network status, and current configuration.
+func (c *Client) GetDeviceInfo() (*models.DeviceInfo, error) {
+    // Implementation
+}
+```
+
+### Error Handling
+
+- **Return errors** instead of panicking
+- **Wrap errors** with context using `fmt.Errorf`
+- **Create custom error types** for specific conditions
+- **Validate inputs** and return helpful error messages
+
+```go
+// Good error handling example
+func (c *Client) SetVolume(level int) error {
+    if level < 0 || level > 100 {
+        return fmt.Errorf("volume level %d out of range [0-100]", level)
+    }
+    
+    if err := c.post("/volume", volumeXML); err != nil {
+        return fmt.Errorf("failed to set volume to %d: %w", level, err)
+    }
+    
+    return nil
+}
+```
+
+### API Design
+
+- **Consistent method naming**: `Get*`, `Set*`, `Send*`, etc.
+- **Return pointers** for complex types, values for simple types
+- **Accept contexts** for potentially long-running operations
+- **Provide convenience methods** for common operations
+
+## Testing Guidelines
+
+### Test Structure
+
+```go
+func TestClient_SetVolume(t *testing.T) {
+    tests := []struct {
+        name          string
+        volume        int
+        expectedError string
+        setupMock     func(*httptest.Server)
+    }{
+        {
+            name:   "valid volume level",
+            volume: 50,
+            setupMock: func(server *httptest.Server) {
+                // Mock setup
+            },
+        },
+        {
+            name:          "volume too high",
+            volume:        150,
+            expectedError: "volume level 150 out of range",
+        },
+    }
+    
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            // Test implementation
+        })
+    }
+}
+```
+
+### Test Categories
+
+1. **Unit Tests**: Test individual functions with mocks
+2. **Integration Tests**: Test with real devices (when available)
+3. **Benchmark Tests**: Performance testing for critical paths
+
+### Mock Usage
+
+Use `httptest.Server` for HTTP client testing:
+

+    }))
+}
+```
+
+### Real Device Testing
+
+When possible, test with real SoundTouch devices:
+
+```bash
+# Set device IP for integration tests
+export SOUNDTOUCH_HOST=192.168.1.100
+go test -tags integration ./pkg/client/
+```
+
+## Documentation Guidelines
+
+### Code Documentation
+
+- **Package documentation** for every package
+- **Function documentation** for all public functions
+- **Example documentation** for complex usage
+
+```go
+// Package client provides a comprehensive HTTP client for the Bose SoundTouch Web API.
+//
+// The client supports all documented SoundTouch endpoints including device information,
+// playback control, volume management, and real-time WebSocket events.
+//
+// Basic usage:
+//
+//     client := client.NewClient(&client.Config{
+//         Host: "192.168.1.100",
+//         Port: 8090,
+//     })
+//     
+//     info, err := client.GetDeviceInfo()
+//     if err != nil {
+//         log.Fatal(err)
+//     }
+//     
+//     fmt.Printf("Device: %s\n", info.Name)
+package client
+```
+
+### User Documentation
+
+- **README.md**: Overview and quick start
+- **API documentation**: Comprehensive endpoint reference
+- **Examples**: Real-world usage patterns
+- **Troubleshooting**: Common issues and solutions
+
+### Documentation Updates
+
+When making changes:
+
+1. **Update relevant docs** in the same PR
+2. **Include usage examples** for new features
+3. **Update CLI help text** if applicable
+4. **Test documentation** (ensure examples work)
+
+## Device Testing
+
+### Supported Devices
+
+The library has been tested with:
+
+- **SoundTouch 10** (firmware unknown)
+- **SoundTouch 20** (firmware unknown)
+
+### Testing New Devices
+
+If you have access to other SoundTouch models:
+
+1. **Run discovery** to find devices:
+   ```bash
+   ./soundtouch-cli discover devices
+   ```
+
+2. **Test basic functionality**:
+   ```bash
+   ./soundtouch-cli -h 192.168.1.100 info get
+   ./soundtouch-cli -h 192.168.1.100 now-playing get
+   ```
+
+3. **Report compatibility** in your PR or issue
+4. **Include device information** from the info endpoint
+
+### Testing Protocol
+
+For significant changes:
+
+1. **Test on multiple devices** if available
+2. **Test error scenarios** (device offline, network issues)
+3. **Test edge cases** (invalid inputs, boundary conditions)
+4. **Document any device-specific behavior**
+
+## Reporting Issues
+
+### Security Issues
+
+**Do not open public issues for security vulnerabilities.** Instead:
+
+1. **Email the maintainers** with details
+2. **Allow reasonable time** for response
+3. **Coordinate disclosure** timing
+
+### Bug Reports
+
+Use the bug report template and include:
+
+- **Device model and firmware** (if known)
+- **Complete error messages and logs**
+- **Minimal reproduction case**
+- **Environment information**
+
+### Feature Requests
+
+Use the feature request template and include:
+
+- **Clear description** of the desired functionality
+- **Use case explanation** 
+- **API documentation reference** (if applicable)
+- **Alternative solutions** you've considered
+
+## Community
+
+### Communication Channels
+
+- **GitHub Issues**: Bug reports, feature requests
+- **GitHub Discussions**: Questions, ideas, general discussion
+- **Pull Requests**: Code contributions and reviews
+

+# soundtouch-backup
+
+A standalone tool for backing up Bose SoundTouch data — both your **cloud account** (presets, devices, sources) and the **local filesystem** of each speaker — before the Bose cloud services shut down on May 6, 2026.
+
+## Overview
+
+| Subcommand | What it backs up                                                                                   |
+|------------|----------------------------------------------------------------------------------------------------|
+| `all`      | Cloud account **and** all paired speakers in one step — the recommended starting point             |
+| `cloud`    | Bose account profile, paired devices, cloud presets, music service sources                         |
+| `local`    | Speaker HTTP API data (presets, sources, volume, …) and optionally device filesystem files via SSH |
+
+Output is a single `.tar.gz` archive (or `.zip`) with a dated root directory.
+
+## Building
+
+```bash
+make build-backup
+# binary: ./build/soundtouch-backup
+```
+
+Or install alongside the other tools:
+
+```bash
+make install
+```
+
+## Usage
+
+### Combined backup (recommended)
+
+The `all` command is the simplest way to capture everything: it authenticates with the Bose cloud, backs up your account data, then reads the IP addresses from `devices.xml` and backs up each reachable speaker over HTTP.
+
+```bash
+# Interactive — prompts for email and password
+soundtouch-backup all
+
+# Non-interactive
+soundtouch-backup all --email you@example.com --password secret
+
+# Include SSH filesystem backup for each speaker
+soundtouch-backup all --ssh
+
+# Environment variables
+BOSE_EMAIL=you@example.com BOSE_PASSWORD=secret soundtouch-backup all --ssh
+```
+
+**Flags**
+
+| Flag         | Short  | Default                               | Description                                            |
+|--------------|--------|---------------------------------------|--------------------------------------------------------|
+| `--email`    | `-e`   | —                                     | Bose account email (`$BOSE_EMAIL`)                     |
+| `--password` | `--pw` | —                                     | Bose account password (`$BOSE_PASSWORD`)               |
+| `--ssh`      |        | on                                    | Also capture filesystem files via SSH for each speaker |
+| `--output`   | `-o`   | `soundtouch-backup-YYYY-MM-DD.tar.gz` | Output archive path                                    |
+| `--format`   |        | `tar.gz`                              | Archive format: `tar.gz` or `zip`                      |
+
+Speakers that are offline or unreachable at the time of backup are skipped with a `✗` warning; the cloud data is still saved.
+
+---
+
+### Cloud backup
+
+Backs up data from your Bose account at `streaming.bose.com`. Credentials are prompted interactively if not supplied as flags.
+
+```bash
+# Interactive — prompts for email, masked password input
+soundtouch-backup cloud
+
+# Non-interactive
+soundtouch-backup cloud --email you@example.com --password secret
+
+# Environment variables (avoids secrets in shell history)
+BOSE_EMAIL=you@example.com BOSE_PASSWORD=secret soundtouch-backup cloud
+
+# Zip output
+soundtouch-backup cloud --format zip --output my-bose-cloud.zip
+```
+
+**Flags**
+
+| Flag         | Short  | Default                               | Description                                       |

+| `--password` | `--pw` | —                                     | Bose account password (`$BOSE_PASSWORD`)          |
+| `--output`   | `-o`   | `soundtouch-backup-YYYY-MM-DD.tar.gz` | Output archive path (`$SOUNDTOUCH_BACKUP_OUTPUT`) |

+Running `cloud` and `local` separately produces two archives. To combine them, use the same `--output` path for both invocations — each adds its own subdirectory so they won't collide (`.tar.gz` does not support appending; use `--format zip` if you need a single archive from two runs, or just keep them separate).

+# SoundTouch Web Implementation
+
+## Overview
+
+The `soundtouch-web` tool provides a modern single-page application (SPA) for controlling Bose SoundTouch devices. Built with a JSON API backend and client-side JavaScript rendering, it offers superior performance and eliminates template rendering issues.
+
+## Architecture
+
+### Single-Page Application Design
+
+The architecture eliminates Go template dependencies and provides:
+- **JSON API Backend**: Pure Go server returning only JSON responses
+- **Client-Side Rendering**: JavaScript handles all HTML generation
+- **WebSocket Real-time**: Bi-directional communication for live updates
+- **Better Performance**: No server-side template processing
+- **Easier Development**: Clear separation of frontend/backend concerns
+
+### Core Components
+
+#### 1. Main Application (`main.go`)
+- **Entry Point**: Handles command-line arguments and application initialization
+- **SPA Routing**: Serves static HTML file for all non-API routes
+- **Device Discovery**: Automatic discovery of SoundTouch devices using unified discovery service
+- **JSON API Server**: Configures API routes and serves the SPA
+- **Context Management**: Proper context handling for timeouts and cancellation
+
+#### 2. HTTP Handlers (`handlers/handlers.go`)
+- **WebApp Structure**: Central application state management
+- **JSON API Endpoints**: RESTful API returning only JSON responses
+- **Device Control**: Device control with proper validation and error handling
+- **Modular Design**: Separated control actions into focused functions
+
+#### 3. WebSocket Support (`handlers/websocket.go`)
+- **Real-time Updates**: Live device status streaming to web clients
+- **Device WebSocket Connections**: Maintains persistent connections to SoundTouch devices
+- **Event Handling**: Processes nowPlaying, volume, and connection state updates
+- **Status Synchronization**: Keeps device status current across all connected clients
+
+#### 4. Type Definitions (`webtypes/types.go`)
+- **Device Management**: Structures for device connections and status
+- **API Responses**: Standardized JSON response format
+- **WebSocket Messages**: Real-time message types
+- **Template Data**: HTML template data structures
+
+### Key Features Implemented
+
+#### Device Discovery & Management
+- **Auto-discovery**: Finds SoundTouch devices on local network using mDNS/UPnP
+- **Multi-device Support**: Manages multiple devices simultaneously
+- **Connection Tracking**: Monitors device availability and connection status
+- **Device Information**: Displays device details (name, type, IP address)
+
+#### Real-time Control Interface
+- **Now Playing**: Live track information with artwork display
+- **Playback Controls**: Play/pause/stop/next/previous with visual feedback
+- **Volume Control**: Real-time volume slider with mute functionality
+- **Bass Adjustment**: Bass level control for supported devices
+- **Preset Management**: Quick access to saved presets (1-6)
+- **Source Selection**: Input switching (Spotify, TuneIn, Bluetooth, AUX, etc.)
+
+#### Web Interface
+- **Single-Page Application**: Self-contained HTML file with embedded CSS and JavaScript
+- **Responsive Design**: Bootstrap 5-based UI optimized for desktop and mobile
+- **Client-Side Routing**: JavaScript handles page navigation without page reloads
+- **Dynamic Rendering**: All HTML generated client-side from JSON data
+- **Real-time Updates**: WebSocket-powered live status updates
+- **Performance Optimized**: Fast loading and no template rendering delays
+
+#### API Endpoints
+```

+- **Network statistics** and device health monitoring
+
+## Screenshots
+
+### Main Device Overview
+The main page shows all discovered devices with their current status, now-playing information, and quick controls.
+
+### Detailed Device Control
+Individual device pages provide full control over:
+- Detailed now-playing information with artwork
+- Comprehensive audio controls (volume, bass)
+- Full preset and source selection
+- Real-time status updates
+
+## Installation
+
+### Prerequisites
+- Go 1.21 or later
+- Access to SoundTouch devices on the same network
+- Modern web browser with WebSocket support
+
+### Building
+```bash
+# From project root
+make build
+
+# Or manually
+cd cmd/soundtouch-web
+go build -o soundtouch-web
+```
+
+### Running
+```bash
+# Run with default settings (port 8080)
+./soundtouch-web
+
+# Specify custom port
+./soundtouch-web -port 8888
+
+# Connect to specific device
+./soundtouch-web -host 192.168.1.100

+```
+
+## Usage
+
+### Accessing the Interface
+1. Start the application
+2. Open your web browser and navigate to `http://localhost:8080`
+3. Click "Discover Devices" to find SoundTouch devices on your network
+4. Click on any device for detailed control, or use quick controls from the main page
+
+### Device Discovery
+The application automatically discovers SoundTouch devices using:
+- **mDNS discovery** for local network devices
+- **UPnP/SSDP discovery** as fallback
+- **Manual device addition** via IP address
+
+### Real-time Updates
+The interface maintains WebSocket connections to each device for instant updates of:
+- Now playing information and artwork
+- Volume and audio settings changes
+- Playback status (play/pause/stop)
+- Connection status and device health
+
+### Responsive Design
+- **Desktop**: Full-featured interface with side-by-side panels
+- **Tablet**: Optimized layout with touch-friendly controls
+- **Mobile**: Stacked interface with gesture support
+
+## API Endpoints
+
+The web UI exposes a REST API for programmatic control:
+
+### Device Management
+```
+GET  /api/devices           # List all discovered devices
+GET  /api/device/{id}       # Get specific device info
+POST /api/discover          # Trigger device discovery
+```
+
+### Device Control
+```
+GET  /api/control/{id}/play        # Start playback
+GET  /api/control/{id}/pause       # Pause playback
+GET  /api/control/{id}/stop        # Stop playback
+GET  /api/control/{id}/next        # Next track
+GET  /api/control/{id}/previous    # Previous track
+POST /api/control/{id}/volume      # Set volume (body: {"level": 50})
+GET  /api/control/{id}/mute        # Mute audio
+GET  /api/control/{id}/unmute      # Unmute audio
+POST /api/control/{id}/bass        # Set bass (body: {"level": 0})
+GET  /api/control/{id}/preset?id=1 # Select preset
+GET  /api/control/{id}/source?name=SPOTIFY # Select source
+```
+
+### WebSocket Events
+Connect to `/ws` for real-time updates:
+```javascript
+const ws = new WebSocket('ws://localhost:8080/ws');
+ws.onmessage = function(event) {
+    const data = JSON.parse(event.data);
+    // Handle device updates, status changes, etc.
+};
+```
+
+## Architecture
+
+### Single-Page Application Architecture
+- **JSON API Backend**: Go server providing RESTful endpoints
+- **Client-Side Rendering**: JavaScript handles all UI rendering
+- **WebSocket Real-time**: Bi-directional real-time communication
+- **No Template Dependencies**: Eliminates server-side template issues
+
+### Backend Components
+- **Discovery Service**: Finds and manages SoundTouch devices
+- **WebSocket Manager**: Maintains real-time connections to devices
+- **JSON API Server**: RESTful interface returning only JSON
+- **Device Manager**: Tracks device state and health
+
+### Frontend Components
+- **Bootstrap 5**: Modern responsive UI framework
+- **Vanilla JavaScript**: No framework dependencies, fast loading
+- **WebSocket Client**: Real-time bidirectional communication
+- **Dynamic Rendering**: Client-side HTML generation from JSON
+
+### Communication Flow
+1. **SPA Loading**: Single HTML file with embedded CSS and JavaScript
+2. **JSON API**: Device discovery and control via REST endpoints
+3. **WebSocket (Device)**: Real-time status updates from SoundTouch devices
+4. **WebSocket (Browser)**: Real-time UI updates to web clients
+5. **Client Rendering**: JavaScript dynamically creates all UI elements
+

+```
+
+### Adding New Features
+1. **API Endpoints**: Add new JSON routes in `setupRoutes()` and `handlers.go`
+2. **WebSocket Events**: Extend event handlers in WebSocket client
+3. **UI Components**: Add JavaScript rendering functions in `static/index.html`
+4. **Device Controls**: Implement new control commands and update client-side handlers
+
+### Testing
+```bash
+# Unit tests
+go test ./...
+
+# Manual testing with multiple devices
+./soundtouch-web -port 8080
+
+# API testing
+curl http://localhost:8080/api/devices
+```
+
+## WebSocket Protocol Analysis
+
+This UI is based on extensive analysis of captured SoundTouch WebSocket interactions, including:
+
+### Message Types Implemented
+- **SoundTouchSdkInfo**: Initial handshake and version info
+- **nowPlayingUpdated**: Real-time track information
+- **volumeUpdated**: Audio level changes
+- **recentsUpdated**: Recently played items
+- **userActivityUpdate**: User interaction notifications
+
+### Request/Response Patterns
+- **Device Information**: System details and capabilities
+- **Audio Controls**: Volume, bass, mute controls
+- **Playback Control**: Play/pause/stop/skip commands
+- **Source Selection**: Input switching (Spotify, TuneIn, etc.)
+- **Preset Management**: Saved station/playlist access
+
+### Gabbo Protocol Features
+- **Persistent Connections**: Maintains long-lived WebSocket connections
+- **Request Correlation**: Uses request IDs for response matching
+- **Real-time Events**: Instant updates for all device state changes
+- **Bi-directional Control**: Both status monitoring and device control
+
+## Browser Compatibility
+
+### Supported Browsers
+- **Chrome 80+** (recommended)
+- **Firefox 75+**
+- **Safari 13+**
+- **Edge 80+**
+
+### Required Features
+- WebSocket support
+- CSS Grid and Flexbox
+- ES6 JavaScript features
+- Responsive CSS media queries
+
+## Security Considerations
+
+- **Local Network Only**: Designed for local network device control
+- **No Authentication**: Assumes trusted local network environment
+- **CORS Policy**: Restricted to same-origin requests
+- **WebSocket Security**: Uses same-origin WebSocket connections
+
+## Troubleshooting
+
+### Common Issues
+
+**Devices Not Found**
+- Ensure devices are on the same network
+- Check firewall settings (ports 8090, 8080)
+- Click "Discover Devices" button to trigger discovery
+
+**WebSocket Connection Failed**
+- Verify device supports WebSocket connections
+- Check browser console for connection errors
+- Refresh the page to reconnect WebSocket
+
+**Control Commands Not Working**
+- Check device is powered on and connected
+- Verify device is not in exclusive mode (e.g., Spotify Connect active)
+- Look for error notifications in the UI
+
+**Page Shows Template Errors**
+- This has been fixed in the SPA implementation
+- Ensure you're accessing the correct URL (localhost:8080)
+- Clear browser cache if you see old template-based content
+
+### Debug Mode
+Add verbose logging by setting environment variable:
+```bash
+export DEBUG=true
+./soundtouch-web
+```
+
+## Contributing
+
+This web UI is part of the larger SoundTouch Go library project. See the main project README for contribution guidelines.
+
+### Architecture Benefits
+The new SPA approach provides:
+- **Better Performance**: No server-side template rendering
+- **Easier Development**: Clear separation of frontend/backend
+- **Mobile Ready**: Same JSON API can power mobile apps
+- **Scalable**: Single-page app architecture
+
+### Feature Requests
+Based on WebSocket interaction analysis, potential future features:
+- Zone/multi-room management
+- Clock display control
+- Software update management
+- Advanced preset programming
+- Progressive Web App (PWA) features

+// Package soundtouch provides a comprehensive Go library, CLI tool, and local service for controlling and emulating Bose SoundTouch devices.
+//
+// This project implements the complete Bose SoundTouch Web API, enabling programmatic control
+// of SoundTouch speakers including playback control, volume management, source selection,
+// multiroom zone management, and real-time event monitoring.
+//
+// It also provides a local service (`soundtouch-service`) that can emulate the Bose Cloud,
+// allowing for offline control and enhanced debugging through HTTP interaction recording.
+//
+// # Quick Start
+//
+// Install the library:
+//
+//	go get github.com/gesellix/bose-soundtouch
+//
+// Basic usage example:
+//
+//	package main
+//
+//	import (
+//		"fmt"
+//		"log"
+//
+//		"github.com/gesellix/bose-soundtouch/pkg/client"
+//	)
+//
+//	func main() {
+//		// Create a client for your SoundTouch device
+//		config := &client.Config{
+//			Host: "192.168.1.100",
+//			Port: 8090,
+//		}
+//		client := client.NewClient(config)
+//
+//		// Get device information
+//		info, err := client.GetInfo()
+//		if err != nil {
+//			log.Fatal(err)
+//		}
+//		fmt.Printf("Device: %s\n", info.Name)
+//
+//		// Control playback
+//		err = client.Play()
+//		if err != nil {
+//			log.Fatal(err)
+//		}
+//	}
+//
+// # SoundTouch Service
+//
+// The `soundtouch-service` provides several advanced features:
+//
+//   - Bose Cloud Emulation: Allows speakers to work without an internet connection.
+//   - HTTP Interaction Recording: Captures all traffic as IntelliJ-compatible .http files.
+//   - Speaker Migration: Automated tools to redirect speakers to the local service.
+//   - Web Interface: A management dashboard for proxy settings and speaker setup.
+//
+// Install the service:
+//
+//	go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-service@latest
+//
+// # CLI Tool
+//
+// The package includes a comprehensive CLI tool for device control:
+//
+//	# Install the CLI
+//	go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-cli@latest
+//
+//	# Discover devices
+//	soundtouch-cli discover devices
+//
+//	# Control a device
+//	soundtouch-cli --host 192.168.1.100 play start
+//

-Retrieves network information.
-
-### GET /capabilities ✅ **Implemented**
-Retrieves device capabilities.
-
-### GET /name 🔍 **Extra** 
-Retrieves the device name.
-
-**Note**: Official API only documents `POST /name` for setting device name. Our GET implementation appears to be an undocumented extension.
-
-### POST /name ❌ **Missing**
-Sets the device name.
-
-**Official Request Format:**
-```xml
-<name>$STRING</name>
-```
-
-### GET /bassCapabilities ❌ **Missing**
-Checks if bass customization is supported on the device.
-
-**Official Response Format:**
-```xml
-<bassCapabilities deviceID="$MACADDR">
-    <bassAvailable>$BOOL</bassAvailable>
-    <bassMin>$INT</bassMin>
-    <bassMax>$INT</bassMax>
-    <bassDefault>$INT</bassDefault>
-</bassCapabilities>
-```
-
-### GET /trackInfo ❌ **Missing**
-Gets track information (appears to be duplicate of `/now_playing`).
-
-**Note**: Official API documents this as separate endpoint but with identical response format to `/now_playing`.
-
-### Zone Slave Management ⚠️ **Different Implementation**
-Our implementation uses high-level methods instead of official endpoints:
-- **Official**: `/addZoneSlave` (POST) - Add slave to zone
-- **Official**: `/removeZoneSlave` (POST) - Remove slave from zone  
-- **Our Implementation**: `AddToZone()` and `RemoveFromZone()` methods via `/setZone`
-
-**Status**: Functionally equivalent and arguably cleaner approach.
-
-### Advanced Audio Controls ❌ **Missing**
-Professional/high-end device features (only available via `/capabilities` check):
-
-#### `/audiodspcontrols` - GET/POST
-Access DSP settings including audio modes and video sync delay.
-
-#### `/audioproducttonecontrols` - GET/POST  
-Advanced bass and treble controls (beyond basic `/bass` endpoint).
-
-#### `/audioproductlevelcontrols` - GET/POST
-Speaker level controls for front-center and rear-surround speakers.
-
-### Clock and Network Endpoints 🔍 **Extra**
-These endpoints work with real hardware but are NOT in official API v1.0:
-- `GET/POST /clockTime` ✅ **Implemented** - Device time management
-- `GET/POST /clockDisplay` ✅ **Implemented** - Clock display settings  
-- `GET /networkInfo` ✅ **Implemented** - Network information
-
-### Balance Control 🔍 **Extra**
-- `GET/POST /balance` ✅ **Implemented** - Stereo balance adjustment
-
-**Note**: Not documented in official API v1.0 but works with real devices.
-
-## Coverage Summary
-
-### Official API Coverage: 94%
-- **Total Official Endpoints**: 19
-- **Implemented**: 15 (79%)
-- **Missing Low-Impact**: 4 (21%)
-
-### Feature Coverage: 100%
-- ✅ All essential user functionality implemented
-- ✅ All core device operations supported
-- ✅ Complete WebSocket event system
-- ✅ Full multiroom capabilities
-- 🔍 Additional features beyond official specification
-
-
-## Error Handling
-
-The API uses standard HTTP status codes:
-- `200 OK` - Successful request
-- `400 Bad Request` - Invalid request
-- `404 Not Found` - Endpoint or resource not found
-- `500 Internal Server Error` - Internal device error
-
-## Example Implementation
-
-```go
-// Example for a GET request
-func GetNowPlaying(deviceIP string) (*NowPlaying, error) {
-    url := fmt.Sprintf("http://%s:8090/now_playing", deviceIP)
-    resp, err := http.Get(url)
-    if err != nil {
-        return nil, err
-    }
-    defer resp.Body.Close()
-    
-    var nowPlaying NowPlaying
-    err = xml.NewDecoder(resp.Body).Decode(&nowPlaying)
-    return &nowPlaying, err
-}
-
-// Example for a POST request
-func SendKey(deviceIP string, key string) error {
-    url := fmt.Sprintf("http://%s:8090/key", deviceIP)
-    xmlData := fmt.Sprintf(`<key state="press" sender="GoClient">%s</key>`, key)
-    
-    resp, err := http.Post(url, "application/xml", strings.NewReader(xmlData))
-    if err != nil {
-        return err
-    }
-    resp.Body.Close()
-    return nil
-}
-```
-
-## Notes
-
-1. **XML Namespace**: Most responses use no explicit XML namespace
-2. **Encoding**: UTF-8 is used for all XML documents
-3. **Timeouts**: Recommended timeout for HTTP requests: 10 seconds
-4. **Rate Limiting**: No explicit limits documented, but moderate usage recommended
-5. **Device Discovery**: Devices can be found via UPnP on the local network
-

+
+## WebSocket Events
+
+Navigation and station operations generate WebSocket events:
+
+### presetsUpdated
+
+Generated when stations are added/removed that affect presets.
+
+```xml
+<presetsUpdated deviceID="A81B6A536A98">
+  <presets>
+    <!-- Updated preset list -->
+  </presets>
+</presetsUpdated>
+```
+
+### nowPlayingUpdated
+
+Generated when station operations affect current playback.
+
+```xml
+<nowPlayingUpdated deviceID="A81B6A536A98">
+  <nowPlaying source="PANDORA">
+    <ContentItem source="PANDORA" location="R456" sourceAccount="user123" isPresetable="true">
+      <itemName>Taylor Swift Radio</itemName>
+    </ContentItem>
+    <track>Love Story</track>
+    <artist>Taylor Swift</artist>
+    <playStatus>PLAY_STATE</playStatus>
+  </nowPlaying>
+</nowPlayingUpdated>
+```
+
+---
+
+## Best Practices
+
+### Parameter Validation
+
+Always validate parameters before API calls:
+
+```go
+func validateNavigateParams(source string, startItem, numItems int) error {
+    if source == "" {
+        return fmt.Errorf("source cannot be empty")
+    }
+    if startItem < 1 {
+        return fmt.Errorf("startItem must be >= 1")
+    }
+    if numItems < 1 {
+        return fmt.Errorf("numItems must be >= 1")
+    }
+    return nil
+}
+```
+
+### Error Handling
+
+Handle both network and API errors:
+
+```go
+response, err := client.Navigate("TUNEIN", "", 1, 25)
+if err != nil {
+    // Check if it's a known API error
+    if strings.Contains(err.Error(), "not available") {
+        log.Printf("TuneIn not configured on device")
+        return
+    }
+    return fmt.Errorf("navigation failed: %w", err)
+}
+```
+
+### Pagination
+
+Use appropriate page sizes for different contexts:
+
+```go
+// Small pages for interactive browsing
+response, err := client.Navigate("TUNEIN", "", 1, 25)
+
+// Larger pages for bulk processing
+response, err := client.Navigate("STORED_MUSIC", "device/0", 1, 100)
+```
+
+### Resource Management
+
+Cache frequently accessed data:
+
+```go
+type CachedClient struct {
+    client      *client.Client
+    sources     *models.Sources
+    sourcesTime time.Time
+}
+
+func (c *CachedClient) GetSources() (*models.Sources, error) {
+    if c.sources == nil || time.Since(c.sourcesTime) > 5*time.Minute {
+        var err error
+        c.sources, err = c.client.GetSources()
+        c.sourcesTime = time.Now()
+        return c.sources, err
+    }
+    return c.sources, nil
+}
+```

+- LOCAL_INTERNET_RADIO with direct streams
+- LOCAL_MUSIC content selection
+- STORED_MUSIC content selection
+- Generic ContentItem usage
+
+## 🔍 streamUrl Format Support
+
+### What is the streamUrl Format?
+The streamUrl format uses a proxy server that accepts the actual stream URL as a parameter:
+
+```
+http://contentapi.gmuth.de/station.php?name=StationName&streamUrl=ActualStreamURL
+```
+
+### Implementation Details
+- **Full Support**: All streamUrl format URLs work seamlessly
+- **Example from Wiki**: Exact implementation matches the wiki specification
+- **ContentItem Structure**:
+  ```go
+  contentItem := &models.ContentItem{
+      Source:       "LOCAL_INTERNET_RADIO",
+      Type:         "stationurl",
+      Location:     "http://contentapi.gmuth.de/station.php?name=Antenne%20Chillout&streamUrl=https://stream.antenne.de/chillout/stream/aacp",
+      IsPresetable: false,
+      ItemName:     "Antenne Chillout",
+      ContainerArt: "https://www.radio.net/300/antennechillout.png",
+  }
+  ```
+
+## 🏗️ Architecture
+
+### Design Principles
+1. **Consistency**: All methods follow the same parameter patterns
+2. **Flexibility**: `SelectContentItem()` allows maximum control
+3. **Convenience**: Specific methods (`SelectLocalInternetRadio()`, etc.) provide simpler interfaces
+4. **Validation**: Comprehensive input validation with clear error messages
+5. **Defaults**: Sensible defaults when optional parameters are empty
+
+### ContentItem Construction
+All convenience methods create properly structured `ContentItem` objects:
+- Automatic `Type` assignment based on source
+- `IsPresetable` defaults to `true`
+- Default `ItemName` when not provided
+- Proper source-specific validation
+
+## 🎵 Related Features
