feat(soundtouch-web): add multi-room zone management

Backend:
- GET /api/zone/{id} — zone info enriched with device names and role flags
- POST /api/zone/{id}/add/{slaveId} — add slave (creates zone if standalone)
- POST /api/zone/{id}/remove/{slaveId} — remove slave from zone
- POST /api/zone/{id}/dissolve — dissolve zone to standalone
- POST /api/zone/{id}/leave — slave leaves its zone (backend finds master)

Frontend (Zone.js):
- Standalone: shows "Group with…" button, opens device picker overlay
- Master: member list with per-row Remove, Add speaker, Dissolve buttons
- Slave: shows master name, Leave zone button
- Lazy-loads on device detail open; refreshes after each zone operation

+# 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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.

+
+### Review Process
+
+- At least one maintainer will review your PR
+- Feedback will be constructive and specific
+- Address feedback in additional commits

+
+## 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

+        return fmt.Errorf("volume level %d out of range [0-100]", level)
+    }
+    
+    if err := c.post("/volume", volumeXML); err != nil {

+    
+    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:
+
+```go
+func setupMockServer() *httptest.Server {
+    return httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        switch r.URL.Path {
+        case "/info":
+            w.Header().Set("Content-Type", "application/xml")
+            fmt.Fprint(w, mockDeviceInfoXML)
+        default:
+            w.WriteHeader(http.StatusNotFound)
+        }
+    }))
+}
+```
+
+### 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
+
+### Getting Help

+# 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                                       |
+|--------------|--------|---------------------------------------|---------------------------------------------------|
+| `--email`    | `-e`   | —                                     | Bose account email (`$BOSE_EMAIL`)                |
+| `--password` | `--pw` | —                                     | Bose account password (`$BOSE_PASSWORD`)          |
+| `--output`   | `-o`   | `soundtouch-backup-YYYY-MM-DD.tar.gz` | Output archive path (`$SOUNDTOUCH_BACKUP_OUTPUT`) |
+| `--format`   |        | `tar.gz`                              | Archive format: `tar.gz` or `zip`                 |
+
+**What gets fetched**
+
+| File in archive          | Source endpoint                                                                 |
+|--------------------------|---------------------------------------------------------------------------------|
+| `cloud/emailaddress.xml` | `GET /streaming/account/{id}/emailaddress`                                      |

+| `cloud/full.xml`         | `GET /streaming/account/{id}/full` (may overlap with the above; skipped if 4xx) |
+
+---
+
+### Local backup
+
+Backs up each speaker over its HTTP API on port 8090. With `--ssh`, also captures key filesystem files via SSH.
+
+```bash
+# Auto-discover all speakers on the local network
+soundtouch-backup local
+
+# Specific speaker
+soundtouch-backup local --host 192.168.178.28
+
+# Multiple speakers
+soundtouch-backup local --host 192.168.178.28 --host 192.168.178.35
+
+# Include SSH filesystem backup
+soundtouch-backup local --ssh
+
+# Longer discovery window on busy networks
+soundtouch-backup local --discover-timeout 10s
+```
+

+| `--port`             | `-p`  | `8090`                                | Speaker HTTP port (`$SOUNDTOUCH_PORT`)           |

+
+| File                | Device endpoint |
+|---------------------|-----------------|
+| `info.xml`          | `/info`         |

+
+Endpoints that return HTTP 4xx (not supported on the device model) are silently skipped.

+
+Missing files and directories are silently skipped with a `⚠` warning.

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

+// 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
+//
+// # Supported Features
+//
+//   - ✅ Device Information & Capabilities
+//   - ✅ Playback, Volume, Bass, and Balance Control
+//   - ✅ Source Selection & Preset Management
+//   - ✅ Real-time WebSocket Events

-Retrieves multiroom zone information.
-
-### POST /setZone 🔄 **Planned**
-Configures multiroom zones.
-
-### GET /balance ✅ **Implemented**
-Retrieves balance settings (stereo devices).
-
-### POST /balance ✅ **Implemented**
-Sets balance settings.

-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
+}
+```

+
+### Example Code
+Complete working example demonstrating:
+- LOCAL_INTERNET_RADIO with streamUrl proxy format
+- 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

+# Device Logging & Troubleshooting
+
+Accessing logs from SoundTouch devices is critical for debugging custom service integrations and understanding internal device behavior. This document outlines the methods for collecting logs, as discovered by the **SoundCork** and **ÜberBöse API** communities.
+
+## Log Types
+
+1.  **System Logs**: Internal OS logs (Linux-based) including `dmesg`, `syslog`, and process-specific logs.
+2.  **Traffic Logs**: Real-time HTTP/HTTPS requests sent by the device to cloud or local services.
+3.  **Proxy Logs**: Logs generated by the `soundtouch-service` when it acts as a man-in-the-middle.
+
+---
+
+## 1. Accessing System Logs (Requires Root)
+
+Most SoundTouch devices run a modified Linux distribution. Accessing these logs requires root SSH or Telnet access.
+
+### Enabling Root Access (Remote Services)
+
+Community research (SoundCork Issue #112) has identified a "backdoor" to enable developer services:
+
+1.  **USB Method**:
+    -   Format a USB stick to **FAT32**.
+    -   Create an empty file named `remote_services` (no extension) in the root of the USB stick.
+    -   Insert the stick into the SoundTouch device.
+    -   Reboot the device (power cycle).
+    -   On some models, you may need to hold **4** and **Volume -** on the device while powering on to force a USB check.
+2.  **TAP Command (Legacy)**:
+    -   On older firmware versions, you can connect to port 17000 via Telnet and issue the command: `remote_services on`.
+
+### Making Root Access Persistent
+Once you have logged in as `root` (usually no password or a well-known community password), you can make the access survive reboots without the USB stick:
+```bash
+touch /mnt/nv/remote_services
+/etc/init.d/sshd start
+```
+
+### Viewing Logs
+Once inside via SSH:
+-   **Kernel Logs**: `dmesg`
+-   **System Logs**: `cat /var/log/messages` or `tail -f /tmp/soundtouch.log` (paths vary by firmware).
+-   **Real-time Monitoring**: `logread -f`
+-   **Process List**: `ps w`
+
+#### Pro-Tip: Filtered Real-time Monitoring
+To focus on cloud service and preset interactions (Marge), use the following command on the device:
+```bash
+logread -f | grep -Ei '(marge|preset)'
+```
+This is particularly useful for debugging preset synchronization and service redirection issues.
+
+---
+
+## 2. Traffic Logging & Interception
+
+If you cannot or do not want to root the device, you can monitor its outbound traffic by redirecting it to a proxy.
+
+### Via `soundtouch-service`
+The `soundtouch-service` included in this repository includes a built-in proxy. When a device is migrated to use this service, all of its cloud-bound traffic is logged to the service console.
+
+**Key Traffic to Monitor**:
+-   `POST /v1/scmudc/{deviceId}`: Real-time telemetry events.
+-   `GET /marge/...`: Account and streaming configuration requests.
+-   `POST /streaming/support/power_on`: Boot-time diagnostics.
+
+### Via Packet Sniffing (Advanced)
+If you have a managed switch or a router capable of port mirroring, you can use **Wireshark** or `tcpdump` to capture traffic.
+-   **Filter**: `tcp port 80 or tcp port 443`
+-   **Target**: The IP address of your SoundTouch device.
+
+---
+
+## 3. Troubleshooting Common Issues
+
+### "IsItBose" Validation Failures
+If the device fails to connect to your custom service despite correct configuration, it may be failing the internal `IsItBose` regex check.
+-   **Evidence**: Look for SSL handshake failures or "Unauthorized" errors in your service logs.
+-   **Solution**: See the [Binary Patching section in DEVICE-REDIRECT-METHODS.md](analysis/DEVICE-REDIRECT-METHODS.md#method-3-binary-patching).
+
+### Disappearing Sources (TuneIn/Local Radio)
+If `TUNEIN` or `LOCAL_INTERNET_RADIO` sources disappear after a reboot in an offline environment.
+-   **Cause**: These sources are validated against the cloud only during the initial boot sequence.
+-   **Solution**: Ensure your emulated service is reachable and responding correctly to `/streaming/support/power_on` and `/streaming/sourceproviders` during the device's boot-up.
+
+---
+
+## 4. HTTP Protocol Quirks
+
+### ETag Case-Sensitivity
+Research in **SoundCork Issue #129** revealed a significant bug in the SoundTouch device firmware regarding HTTP `ETag` headers.
+
+- **The Issue**: The device firmware expects the `ETag` header to be exactly title-cased (`ETag`). Many modern web servers or frameworks (like FastAPI/Uvicorn) return headers in all lowercase (`etag`) per HTTP/2 or standard case-insensitive conventions.
+- **The Symptom**: If the server returns a lowercase `etag`, the device fails to recognize it. Consequently, the device will never send an `If-None-Match` header in subsequent requests, breaking preset synchronization and efficient caching.
+- **The Workaround**: If you are using a custom service, you may need to use a reverse proxy (like **Nginx**) or a middleware to force the header casing to `ETag`.
+
+**Example Nginx Fix**:
+```nginx
+proxy_hide_header etag;
+add_header ETag $upstream_http_etag;
+```

+# Bose SoundTouch Device Setup Flow
+
+This document details the multi-step process required to fully set up a Bose SoundTouch device, as derived from the Stockholm firmware (`setup/js/`) analysis.
+
+A complete setup flow involves a sequence of local (WebSocket) and cloud (HTTP) actions that move the device from a factory-reset state to a fully registered, functional system.
+
+## 1. Local Coordination Stage (WebSocket)
+
+Before a device can be controlled, it must be configured on the local network and named. These actions occur via a WebSocket connection to the device on port 8080.
+
+### 1.1 Language Configuration (Optional)
+If the device is in a factory-reset state, the UI typically ensures the device language matches the user's choice.
+- **WebSocket Action**: `set_language`
+- **Internal Logic**: `SetupWizard.js` handles this via `set_device_language`.
+
+### 1.2 Network Configuration (WiFi)
+Configures the device to connect to a specific wireless access point.
+- **File Reference**: `setup/js/workflow_wifi_setup.js`
+- **Logic**: Triggers a site survey, then sends SSID and credentials.
+- **WebSocket Command**: `set_WIFI_OLED` or similar internal method calls to configure the network profile.
+
+### 1.3 Device Naming (Rename Step)
+Assigns a user-friendly name (e.g., "Living Room") to the device.
+- **File Reference**: `setup/js/workflow_rename.js`
+- **WebSocket Action**: `name`
+- **XML Payload**:
+    ```xml
+    <name>Living Room</name>
+    ```
+- **Implementation**: The `RenameDevices.do_rename_devices()` function sends this to the device. The device then updates its local name and mDNS/SSDP broadcasts.
+
+## 2. Cloud Interaction Stage (HTTP)
+
+The device needs to be linked to a Bose "Marge" account to enable cloud-based features and music services.
+
+### 2.1 Account Creation (Registration)
+If a user doesn't have an account, the setup client creates one.
+- **File Reference**: `setup/js/workflow_marge.js`
+- **Cloud Endpoint**: `POST https://streaming.bose.com/streaming/account`
+- **Payload**: XML containing name, email, password, and country.
+- **Content-Type**: `application/vnd.bose.customer-v1.0+xml`
+
+### 2.2 Cloud Authentication (Login)
+The setup client must obtain a valid `accountId` and `userAuthToken` to pair the device.
+- **File Reference**: `setup/js/workflow_marge.js`
+- **Cloud Endpoint**: `POST https://streaming.bose.com/streaming/account/login`
+- **Payload**: XML containing username and password.
+- **Content-Type**: `application/vnd.bose.streaming-v1.2+xml`
+- **Result**: Returns a session token in the `Credentials` response header and the user's `account ID` in the XML body.
+
+## 3. Registration Bridge (WebSocket to Cloud)
+
+This is the final "pairing" step where the client tells the device which account it belongs to.
+
+### 3.1 Device Registration (The "Pair" Step)
+The client sends the user's credentials to the device, which then registers itself with the cloud.
+- **File Reference**: `setup/js/workflow_add_devices.js`
+- **WebSocket Action**: `setMargeAccount`
+- **XML Payload**:
+    ```xml
+    <PairDeviceWithAccount>
+        <accountId>12345</accountId>
+        <userAuthToken>jGwE... (truncated)</userAuthToken>
+    </PairDeviceWithAccount>
+    ```
+- **Device Reaction**: Upon receiving this, the device makes its own outbound HTTP POST to the Marge service:
+    `POST https://streaming.bose.com/{accountId}/devices`
+
+## 4. Finalization
+
+Once the registration is complete, the setup application (Stockholm) performs final cleanup. It's important to distinguish between **App State** (the Stockholm UI's persistent settings) and **Device State** (the physical speaker's configuration).
+
+### 4.1 Exiting Setup Mode (App Settings)
+The Stockholm app communicates with its "native container" (the WebView bridge on iOS/Android/Windows/macOS) using a `setData` command in **JSON format**. This is an internal message to the application's persistent storage, **not a network command sent to the physical speaker**.
+
+This command tells the Stockholm app which page to load on startup, effectively marking the setup as complete in the UI.
+
+- **Internal Command**: `setData`
+- **Parameter**: `startupPage`
+- **Normal Value**: `index.html` (Normal mode)
+- **Setup Value**: `setup/index.html` (Setup mode)
+
+**JSON Payload (Internal to Stockholm App)**:
+```json
+{
+    "method": "setData",
+    "params": {
+        "name": "startupPage",
+        "value": "index.html"
+    }
+}
+```
+
+**Other Common Internal Parameters**:
+- `changeStartupPage`: Set to `false` after a successful setup or update.
+- `tipsEnabled`: Set to `false` to suppress the "Getting Started" tutorials.
+- `promptUpdate`: Set to `true` if a firmware update was deferred during setup.
+
+### 4.2 Device Finalization
+The physical speaker considers the setup "done" once it successfully processes the `<PairDeviceWithAccount>` XML message and completes its own handshake with the Marge cloud. There is no specific "Finalize" XML command sent to the speaker; the successful registration is the signal.
+
+The `SetupWizard.js` calls `single_device_setup_done()` to trigger the internal `setData` updates described above. If these are not saved in the app's local storage, the Stockholm UI may return to the setup flow on next launch, even if the speaker is already paired.
+
+---
+
+## Summary of Scriptable Requirements
+
+To automate a device setup using a custom tool (like `soundtouch-cli`), you must perform the following:
+1.  **Configure WiFi**: (Assumed if device is reachable over IP).
+2.  **Set Name**: Send the `<name>` WebSocket message (XML) to update the device identity.
+3.  **Obtain Token**: Authenticate against the cloud service (Marge) via HTTP.
+4.  **Pair Device**: Send the `<PairDeviceWithAccount>` WebSocket message (XML) with the account ID and token.
+
+**Note**: The JSON `setData` commands are only necessary if you are building/controlling a version of the Stockholm UI itself. They are not required to configure the physical hardware.

+# Technical Proposal: External Service Provider Abstraction
+
+This document outlines a strategy to refactor the SoundTouch Service's content handling into a modular provider-based system.
+
+## 1. Problem Statement
+Currently, content handling for BMX (Bose Media Exchange) services like TuneIn or RadioBrowser is deeply intertwined with the HTTP handlers and XML models. Adding a new content provider (e.g., Local Media, Podcast RSS) requires modifying several files and duplicating boilerplate code for HTTP requests and error handling.
+
+## 2. Proposed Architecture
+
+### 2.1 The Provider Interface
+We define a generic `ContentProvider` interface that abstracts away the source-specific logic (API calls, data parsing).
+
+```go
+package provider
+
+import "github.com/gesellix/bose-soundtouch/pkg/models"
+
+type ContentProvider interface {
+    // ID returns the unique identifier for this provider (e.g. "RADIO_BROWSER")
+    ID() string
+
+    // Resolve returns playback details for a given content identifier
+    Resolve(id string) (*models.BmxPlaybackResponse, error)
+
+    // Search allows finding content within this provider
+    Search(query string) ([]models.ContentItem, error)
+}
+```
+
+### 2.2 Provider Registry
+A central registry in `soundtouch-service` manages the lifecycle and selection of providers.
+
+```go
+type Registry struct {
+    providers map[string]ContentProvider
+}
+
+func (r *Registry) Register(p ContentProvider) { ... }
+func (r *Registry) Get(id string) ContentProvider { ... }
+```
+
+## 3. Implementation Plan
+
+### 3.1 Phase 1: Modularize RadioBrowser
+1.  **Extract Logic**: Move current RadioBrowser logic from `bmx.go` into a new package `pkg/service/providers/radiobrowser`.
+2.  **Add Failover**: Implement the **API Failover** logic inspired by OpenCloudTouch.
+    -   Maintain a list of active RadioBrowser mirrors (e.g., `de1.api.radio-browser.info`, `nl1.api.radio-browser.info`).
+    -   Implement a round-robin or health-based selection strategy.
+3.  **Implements Interface**: Ensure the new package satisfies the `ContentProvider` interface.
+
+### 3.2 Phase 2: Refactor BMX Handlers
+-   Update `HandleTuneInPlayback` and `HandleOrionPlayback` to use the registry.
+-   The handlers will look up the provider based on the request context or URL parameters and delegate the resolution.
+
+### 3.3 Phase 3: Dynamic Service Advertising
+-   Modify `HandleBMXRegistry` to dynamically generate the `bmx_services.json` content based on the currently registered and enabled providers.
+
+## 4. Benefits
+-   **Resilience**: Centralized error handling and failover strategies for all external APIs.
+-   **Extensibility**: New services can be added by simply implementing the interface and registering them at startup.
+-   **Testability**: Providers can be unit-tested in isolation without mocking the entire HTTP server stack.
+-   **Unified UI**: A future Web UI can query the registry to show available content sources and their statuses.
+
+## 5. Next Steps
+1.  Refine the `ContentProvider` interface to include metadata (icons, user-friendly names).
+2.  Create a prototype for the `radiobrowser` provider with failover support.

+  - **Verification**: Tested with SoundTouch 20, confirmed compatibility with curl equivalent (`curl http://<device>:8090/playNotification`)
+
+#### Code Quality Improvements
+- **Consistent HTTP Method Usage**: Leveraged existing client patterns instead of manual HTTP handling
+- **Model Reuse**: Used existing `StationResponse` struct for `/playNotification` XML response parsing
+- **Documentation Updates**: Added troubleshooting guide for speaker notification issues

+# Manual Network Discovery on macOS
+
+This document provides comprehensive guidance for manually discovering network services and devices using built-in macOS tools and command-line utilities. This is particularly useful for troubleshooting network discovery issues or understanding what services are available on your local network.
+
+## Overview
+
+Network service discovery typically relies on two main protocols:
+
+- **mDNS (Multicast DNS)** - Used by Apple devices, printers, and many local services
+- **SSDP (Simple Service Discovery Protocol)** - Used by UPnP devices, media servers, and smart home devices
+
+## mDNS (Multicast DNS) Discovery
+
+**Multicast Address:** `224.0.0.251:5353`
+
+mDNS is the underlying protocol for Bonjour/Zeroconf services. It allows devices to advertise services on the local network using `.local` domain names.
+
+### Built-in Tools (Recommended)
+
+macOS includes `dns-sd`, a powerful command-line tool for service discovery:
+
+```bash
+# Browse for all available service types
+dns-sd -B _services._dns-sd._udp local.
+
+# Browse for specific service types
+dns-sd -B _http._tcp local.           # Web servers
+dns-sd -B _airplay._tcp local.        # AirPlay devices
+dns-sd -B _ipp._tcp local.           # Internet Printing Protocol
+dns-sd -B _soundtouch._tcp local.    # Bose SoundTouch devices
+dns-sd -B _ssh._tcp local.           # SSH servers
+dns-sd -B _afpovertcp._tcp local.    # AFP file sharing
+
+# Resolve a specific service to get IP address and port
+dns-sd -L "ServiceName" _http._tcp local.
+
+# Register a test service (useful for testing)
+dns-sd -R "TestService" _http._tcp local 8080
+
+# Query for a specific record type
+dns-sd -Q hostname.local A          # Get IPv4 address
+dns-sd -Q hostname.local AAAA       # Get IPv6 address
+```
+
+### Using dig Command
+
+The `dig` command can also query mDNS directly:
+
+```bash
+# Query for a specific hostname
+dig @224.0.0.251 -p 5353 hostname.local
+
+# Query for all service types
+dig @224.0.0.251 -p 5353 _services._dns-sd._udp.local PTR
+
+# Query for specific service instances
+dig @224.0.0.251 -p 5353 _http._tcp.local PTR
+
+# Get detailed information with additional records
+dig @224.0.0.251 -p 5353 _soundtouch._tcp.local PTR +additional
+```
+
+### Advanced mDNS Monitoring
+
+```bash
+# Monitor all mDNS traffic (requires sudo)
+sudo tcpdump -i any -n -s 0 'port 5353'
+
+# Monitor specific service announcements
+sudo tcpdump -i any -n -s 0 -A 'port 5353 and host 224.0.0.251'
+
+# Monitor with human-readable timestamps
+sudo tcpdump -i any -n -s 0 -t -A 'port 5353'
+```
+
+### With Homebrew (Optional)
+
+For additional tools, you can install Avahi:
+
+```bash
+brew install avahi
+
+# Browse all services
+avahi-browse -a
+
+# Browse with verbose details
+avahi-browse -a -v -t
+
+# Browse only for a limited time
+avahi-browse -a -t --timeout=10
+
+# Resolve a specific service
+avahi-resolve -n hostname.local
+
+# Publish a test service
+avahi-publish -s "Test Service" _http._tcp 8080
+```
+
+## SSDP (Simple Service Discovery Protocol)
+
+**Multicast Address:** `239.255.255.250:1900`
+
+SSDP is used by UPnP devices to advertise and discover services. It uses HTTP-like messages over UDP multicast.
+
+### Active Discovery (M-SEARCH)
+
+This method sends out discovery requests and waits for responses:
+
+**Terminal 1 - Capture responses:**
+```bash
+# Monitor all SSDP traffic
+sudo tcpdump -i any -n -A 'udp port 1900'
+
+# Monitor with better formatting
+sudo tcpdump -i any -n -s 0 -A 'udp port 1900' | grep -E '(M-SEARCH|HTTP|NOTIFY|ST:|USN:|LOCATION:)'
+```
+
+**Terminal 2 - Send discovery requests:**
+```bash
+# Basic discovery for all devices
+echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:ssdp:all\r\nMan:\"ssdp:discover\"\r\nMX:3\r\n\r\n" | nc -u 239.255.255.250 1900
+
+# Search for specific device types
+echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:urn:schemas-upnp-org:device:MediaRenderer:1\r\nMan:\"ssdp:discover\"\r\nMX:3\r\n\r\n" | nc -u 239.255.255.250 1900
+
+# Search for root devices only
+echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:upnp:rootdevice\r\nMan:\"ssdp:discover\"\r\nMX:3\r\n\r\n" | nc -u 239.255.255.250 1900
+
+# Search with longer timeout for slow devices
+echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:ssdp:all\r\nMan:\"ssdp:discover\"\r\nMX:10\r\n\r\n" | nc -u 239.255.255.250 1900
+```
+
+### Passive Listening (NOTIFY messages)
+
+Devices periodically send NOTIFY messages to announce their presence:
+
+```bash
+# Simple listening (may miss some messages)
+nc -ul 1900
+
+# More reliable listening with proper multicast join
+# First, install socat if not available
+brew install socat
+
+# Listen to multicast SSDP traffic
+socat - UDP4-RECVFROM:1900,ip-add-membership=239.255.255.250:0.0.0.0,fork
+
+# Alternative: bind to specific interface
+socat - UDP4-RECVFROM:1900,ip-add-membership=239.255.255.250:en0,fork
+```
+
+### Python Script for SSDP Discovery
+
+For more reliable and detailed discovery, use this Python script:
+
+```python
+#!/usr/bin/env python3
+"""
+SSDP Discovery Script
+Sends M-SEARCH requests and collects responses from UPnP devices.

+
+### SSDP Message Types
+
+Understanding SSDP message types helps interpret the traffic:
+
+**M-SEARCH Request:**
+```
+M-SEARCH * HTTP/1.1
+HOST:239.255.255.250:1900
+ST:ssdp:all
+MAN:"ssdp:discover"
+MX:3
+```
+
+**NOTIFY Advertisement:**
+```
+NOTIFY * HTTP/1.1
+HOST:239.255.255.250:1900
+CACHE-CONTROL:max-age=1800
+LOCATION:http://192.168.1.100:8090/device_description.xml
+NT:upnp:rootdevice
+NTS:ssdp:alive
+USN:uuid:12345678-1234-1234-1234-123456789012::upnp:rootdevice
+```
+
+**HTTP Response:**
+```
+HTTP/1.1 200 OK
+CACHE-CONTROL:max-age=1800
+DATE:Wed, 18 Dec 2024 10:30:00 GMT
+EXT:
+LOCATION:http://192.168.1.100:8090/device_description.xml
+SERVER:Linux/3.0 UPnP/1.0 Device/1.0
+ST:upnp:rootdevice
+USN:uuid:12345678-1234-1234-1234-123456789012::upnp:rootdevice
+```
+
+## Network Interface Discovery
+
+### Find Your Network Interfaces
+
+```bash
+# List all network interfaces
+ifconfig
+
+# Show only active interfaces with IP addresses
+ifconfig | grep -A 1 "inet "
+
+# Show routing table to find default interface
+netstat -rn | grep default
+
+# Use route command (alternative)
+route get default
+```
+
+### Find Your Network Segment
+
+```bash
+# Get your IP and netmask
+ifconfig en0 | grep inet
+
+# Show ARP table (devices that have communicated recently)
+arp -a
+
+# Scan local network segment (requires nmap)
+brew install nmap
+nmap -sn 192.168.1.0/24  # Adjust network range as needed
+
+# Quick ping sweep (built-in)
+for i in {1..254}; do ping -c 1 -t 1 192.168.1.$i >/dev/null 2>&1 && echo "192.168.1.$i is up"; done
+```
+
+## Troubleshooting Discovery Issues
+
+### Common Problems and Solutions
+
+**1. No responses to mDNS queries:**
+```bash
+# Check if mDNS daemon is running
+sudo launchctl list | grep mDNSResponder
+
+# Restart mDNS if needed (rarely required)
+sudo launchctl kickstart -k system/com.apple.mDNSResponder
+
+# Test basic mDNS functionality
+dns-sd -B _services._dns-sd._udp local.
+```
+
+**2. No responses to SSDP queries:**
+```bash
+# Check if firewall is blocking multicast
+sudo pfctl -sr | grep 1900
+
+# Test multicast connectivity
+ping 239.255.255.250
+
+# Check interface supports multicast
+ifconfig en0 | grep MULTICAST
+```
+
+**3. Network interface issues:**
+```bash
+# Check which interface is being used
+route get 239.255.255.250
+
+# Force specific interface for testing
+ping -I en0 239.255.255.250
+sudo tcpdump -i en0 'port 5353 or port 1900'
+```
+
+**4. Firewall blocking discovery:**
+```bash
+# Check macOS firewall status
+sudo /usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate
+
+# Temporarily disable firewall for testing (BE CAREFUL)
+sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setglobalstate off
+
+# Re-enable firewall after testing
+sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setglobalstate on
+```
+
+### Debugging Tools
+
+**Monitor all discovery traffic:**
+```bash
+# Watch both mDNS and SSDP traffic
+sudo tcpdump -i any -n -s 0 'port 5353 or port 1900'
+
+# Save traffic to file for analysis
+sudo tcpdump -i any -n -s 0 -w discovery.pcap 'port 5353 or port 1900'
+
+# Analyze with specific filters
+sudo tcpdump -i any -n -A 'port 5353' | grep -i soundtouch
+```
+
+**Network connectivity tests:**
+```bash
+# Test multicast group membership
+netstat -g
+
+# Test UDP connectivity
+nc -u 192.168.1.100 8090  # Replace with actual device IP
+
+# Test HTTP connectivity to discovered devices
+curl -i http://192.168.1.100:8090/info  # SoundTouch info endpoint
+```
+
+## Protocol Comparison
+
+| Protocol | Port | Multicast Address | Use Case | Discovery Method |
+|----------|------|------------------|----------|------------------|
+| **mDNS** | 5353 | 224.0.0.251 | Apple devices, printers, local services | Query `.local` names, browse service types |
+| **SSDP** | 1900 | 239.255.255.250 | UPnP devices, media servers, smart home | M-SEARCH requests, NOTIFY advertisements |
+
+## Advanced Techniques
+
+### Continuous Monitoring
+
+Create a script to continuously monitor for new devices:
+
+```bash
+#!/bin/bash
+# continuous_discovery.sh
+
+echo "Starting continuous network discovery monitoring..."
+echo "Press Ctrl+C to stop"
+
+# Function to handle cleanup
+cleanup() {
+    echo -e "\nStopping monitoring..."
+    kill $TCPDUMP_PID 2>/dev/null
+    kill $MDNS_PID 2>/dev/null
+    exit 0
+}
+
+trap cleanup INT TERM
+
+# Start background monitoring
+sudo tcpdump -i any -n -l 'port 5353 or port 1900' &
+TCPDUMP_PID=$!
+
+# Periodic active discovery
+while true; do
+    echo -e "\n--- $(date) - Active Discovery Sweep ---"
+    
+    # mDNS discovery
+    timeout 5 dns-sd -B _services._dns-sd._udp local. &
+    MDNS_PID=$!
+    
+    # SSDP discovery
+    echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:ssdp:all\r\nMan:\"ssdp:discover\"\r\nMX:3\r\n\r\n" | nc -u 239.255.255.250 1900
+    
+    # Wait before next sweep
+    sleep 30
+done
+```
+
+### Device-Specific Queries
+
+For SoundTouch devices specifically:
+
+```bash
+# Look for SoundTouch-specific services
+dns-sd -B _soundtouch._tcp local.
+
+# Query for SoundTouch device descriptions
+dns-sd -L "Bose SoundTouch" _soundtouch._tcp local.
+
+# SSDP query for media renderers (SoundTouch devices often respond)
+echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:urn:schemas-upnp-org:device:MediaRenderer:1\r\nMan:\"ssdp:discover\"\r\nMX:5\r\n\r\n" | nc -u 239.255.255.250 1900
+```
+
+### Creating Test Services
+
+For testing your discovery setup:
+
+```bash
+# Register a test mDNS service
+dns-sd -R "TestDevice" _http._tcp local 8080 &
+TEST_PID=$!
+
+# Test that it can be discovered
+dns-sd -B _http._tcp local.
+
+# Clean up
+kill $TEST_PID
+```
+
+## Security Considerations
+
+- **Network exposure**: Discovery protocols broadcast device information
+- **No authentication**: Discovery traffic is typically unauthenticated
+- **Information disclosure**: Device details may be visible to entire network
+- **Firewall configuration**: Consider allowing only necessary multicast traffic
+
+## Quick Reference
+
+### Essential Commands
+
+```bash
+# Quick mDNS service browse
+dns-sd -B _services._dns-sd._udp local.
+
+# Quick SSDP discovery
+echo -e "M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:ssdp:all\r\nMan:\"ssdp:discover\"\r\nMX:3\r\n\r\n" | nc -u 239.255.255.250 1900
+
+# Monitor all discovery traffic
+sudo tcpdump -i any -n 'port 5353 or port 1900'
+
+# Test specific device connectivity
+curl -i http://device-ip:8090/info
+```
+
+### Common Service Types
+
+| Service Type | Protocol | Description |
+|-------------|----------|-------------|
+| `_http._tcp` | mDNS | Web servers |
+| `_airplay._tcp` | mDNS | AirPlay devices |
+| `_soundtouch._tcp` | mDNS | Bose SoundTouch |
+| `_ipp._tcp` | mDNS | Printers |
+| `_ssh._tcp` | mDNS | SSH servers |
+| `upnp:rootdevice` | SSDP | UPnP root devices |
+| `urn:schemas-upnp-org:device:MediaRenderer:1` | SSDP | Media players |
+
+This guide provides comprehensive tools for manually discovering and troubleshooting network services on macOS. Use these techniques to understand what devices and services are available on your network, debug discovery issues, and verify that your applications are correctly implementing discovery protocols.

+# Navigation and Station Management Guide
+
+## Overview
+
+The Bose SoundTouch Go client provides comprehensive navigation and station management functionality that allows you to:
+
+- **Browse content sources** (TuneIn, Pandora, Spotify, stored music)
+- **Search for stations and content** across music services
+- **Add stations and immediately play them**
+- **Remove stations from collections**
+- **Navigate directory structures** in music libraries
+
+This guide provides complete examples and best practices for using these features.

+
+## Quick Start
+
+### Basic Setup
+
+```go
+package main
+
+import (
+    "fmt"
+    "log"
+    
+    "github.com/gesellix/bose-soundtouch/pkg/client"
+)
+
+func main() {
+    // Create client
+    config := &client.Config{
+        Host: "192.168.1.100",
+        Port: 8090,
+    }
+    soundtouch := client.NewClient(config)
+    
+    // Your navigation code here...
+}
+```
+
+### Simple Navigation Example
+
+```go
+// Browse TuneIn content
+response, err := soundtouch.Navigate("TUNEIN", "", 1, 25)
+if err != nil {
+    log.Fatal(err)
+}
+
+fmt.Printf("Found %d items\n", response.TotalItems)
+for _, item := range response.Items {
+    fmt.Printf("- %s (%s)\n", item.GetDisplayName(), item.Type)
+}
+```
+
+## Content Navigation
+
+### Browse Different Sources
+
+```go
+// Browse TuneIn radio stations
+tuneInStations, err := soundtouch.GetTuneInStations("")
+if err != nil {
+    log.Printf("TuneIn not available: %v", err)
+} else {
+    fmt.Printf("TuneIn has %d items\n", tuneInStations.TotalItems)
+}
+
+// Browse Pandora stations (requires account)
+pandoraStations, err := soundtouch.GetPandoraStations("your_pandora_account")
+if err != nil {
+    log.Printf("Pandora not available: %v", err)
+} else {
+    stations := pandoraStations.GetStations()
+    fmt.Printf("Found %d Pandora stations\n", len(stations))
+}
+
+// Browse stored music library
+musicLibrary, err := soundtouch.GetStoredMusicLibrary("device_account/0")
+if err != nil {
+    log.Printf("Stored music not available: %v", err)
+} else {
+    directories := musicLibrary.GetDirectories()
+    tracks := musicLibrary.GetTracks()
+    fmt.Printf("Music library: %d dirs, %d tracks\n", len(directories), len(tracks))
+}
+```
+
+### Navigate Into Directories
+
+```go
+// First, get the root level
+musicLibrary, err := soundtouch.GetStoredMusicLibrary("device_account/0")
+if err != nil {
+    log.Fatal(err)
+}
+
+// Find a directory to browse into
+directories := musicLibrary.GetDirectories()
+if len(directories) == 0 {
+    fmt.Println("No directories found")
+    return
+}
+
+// Navigate into the first directory
+directory := directories[0]
+fmt.Printf("Browsing into: %s\n", directory.GetDisplayName())
+
+contents, err := soundtouch.NavigateContainer(
+    "STORED_MUSIC",
+    "device_account/0",
+    1, 100,  // Get up to 100 items starting from position 1
+    directory.ContentItem,
+)
+if err != nil {
+    log.Fatal(err)
+}
+
+// Show what's inside
+tracks := contents.GetTracks()
+subdirs := contents.GetDirectories()
+fmt.Printf("Found %d tracks and %d subdirectories\n", len(tracks), len(subdirs))
+
+// List first few tracks
+for i, track := range tracks[:min(5, len(tracks))] {
+    fmt.Printf("%d. %s", i+1, track.GetDisplayName())
+    if track.ArtistName != "" {
+        fmt.Printf(" - %s", track.ArtistName)
+    }
+    if track.AlbumName != "" {
+        fmt.Printf(" [%s]", track.AlbumName)
+    }
+    fmt.Println()
+}
+```
+
+### Advanced Navigation with Pagination
+
+```go
+// Browse large collections with pagination
+const pageSize = 50
+startItem := 1
+
+for {
+    response, err := soundtouch.Navigate("STORED_MUSIC", "device/0", startItem, pageSize)
+    if err != nil {
+        log.Fatal(err)
+    }
+    
+    if len(response.Items) == 0 {
+        break // No more items
+    }
+    
+    fmt.Printf("Page starting at %d: %d items\n", startItem, len(response.Items))
+    
+    // Process this page
+    for _, item := range response.Items {
+        fmt.Printf("  %s (%s)\n", item.GetDisplayName(), item.Type)
+    }
+    
+    // Move to next page
+    startItem += pageSize
+    
+    // Stop if we've seen all items
+    if startItem > response.TotalItems {
+        break
+    }
+}
+```
+
+## Station Search
+
+### Basic Search
+
+```go
+// Search TuneIn for jazz stations
+results, err := soundtouch.SearchTuneInStations("jazz")
+if err != nil {
+    log.Fatal(err)
+}
+
+fmt.Printf("Found %d total results for 'jazz'\n", results.GetResultCount())
+
+// Show different types of results
+songs := results.GetSongs()
+artists := results.GetArtists()
+stations := results.GetStations()
+
+fmt.Printf("Songs: %d, Artists: %d, Stations: %d\n",
+    len(songs), len(artists), len(stations))
+```
+
+### Service-Specific Search
+
+```go
+// Search Pandora (requires account)
+pandoraResults, err := soundtouch.SearchPandoraStations("your_account", "Taylor Swift")
+if err != nil {
+    log.Fatal(err)

+
+songs := spotifyResults.GetSongs()
+for _, song := range songs[:min(5, len(songs))] {
+    fmt.Printf("Song: %s\n", song.GetFullTitle())
+}
+```
+
+### Search Result Analysis
+
+```go
+results, err := soundtouch.SearchPandoraStations("account", "classic rock")
+if err != nil {
+    log.Fatal(err)
+}
+
+// Analyze all results
+for _, result := range results.GetAllResults() {
+    fmt.Printf("Name: %s, Token: %s\n", result.GetDisplayName(), result.Token)
+    
+    // Determine result type
+    switch {
+    case result.IsSong():
+        fmt.Printf("  Type: Song by %s\n", result.Artist)
+    case result.IsArtist():
+        fmt.Printf("  Type: Artist\n")
+    case result.IsStation():
+        fmt.Printf("  Type: Station")

+        fmt.Println("No artists found to create stations from")
+        return
+    }
+    
+    // Get current stations to avoid duplicates
+    currentStations, err := soundtouch.GetPandoraStations(pandoraAccount)
+    if err != nil {
+        log.Printf("Warning: Could not get current stations: %v", err)
+    }
+    
+    // Create a map of existing station names
+    existingStations := make(map[string]bool)
+    for _, station := range currentStations.Items {
+        existingStations[station.GetDisplayName()] = true
+    }
+    
+    // Add stations only if they don't exist
+    for _, artist := range artists[:min(2, len(artists))] {
+        stationName := artist.Name + " Radio"
+        
+        if existingStations[stationName] {
+            fmt.Printf("⚠️  Station already exists: %s\n", stationName)
+            continue
+        }
+        
+        fmt.Printf("Adding new station: %s\n", stationName)
+        err := soundtouch.AddStation("PANDORA", pandoraAccount, artist.Token, stationName)
+        if err != nil {
+            log.Printf("❌ Failed to add %s: %v", stationName, err)
+        } else {
+            fmt.Printf("✓ Added: %s\n", stationName)
+        }
+    }
+}
+```
+
+## Best Practices
+
+### 1. Check Source Availability
+
+```go
+// Always check what sources are available first
+sources, err := soundtouch.GetSources()
+if err != nil {
+    return err
+}
+
+// Check if TuneIn is ready
+for _, source := range sources.SourceItem {
+    if source.Source == "TUNEIN" && source.Status.IsReady() {
+        // TuneIn is available
+        break
+    }
+}
+```
+
+### 2. Use Pagination for Large Collections
+
+```go
+// For large libraries, use pagination
+const batchSize = 50
+
+func processLargeLibrary(soundtouch *client.Client, sourceAccount string) {
+    startItem := 1
+    
+    for {
+        batch, err := soundtouch.Navigate("STORED_MUSIC", sourceAccount, startItem, batchSize)
+        if err != nil {
+            log.Printf("Error at position %d: %v", startItem, err)
+            break
+        }
+        
+        if len(batch.Items) == 0 {
+            break // No more items
+        }
+        
+        // Process this batch
+        processBatch(batch.Items)
+        
+        startItem += batchSize
+        
+        // Prevent infinite loops
+        if startItem > batch.TotalItems {
+            break
+        }
+    }
+}
+```
+
+### 3. Handle Service-Specific Behavior
+
+```go
+func handleServiceDifferences(soundtouch *client.Client) {
+    // TuneIn: Usually no account needed
+    tuneInStations, err := soundtouch.SearchTuneInStations("news")
+    if err == nil {
+        fmt.Printf("TuneIn: %d stations\n", len(tuneInStations.GetStations()))
+    }
+    
+    // Pandora: Requires user account
+    pandoraResults, err := soundtouch.SearchPandoraStations("user_account", "rock")
+    if err == nil {
+        // Pandora returns artists you can create stations from
+        artists := pandoraResults.GetArtists()
+        fmt.Printf("Pandora: %d artists\n", len(artists))
+    }
+    
+    // Spotify: Requires user account, returns tracks/playlists
+    spotifyResults, err := soundtouch.SearchSpotifyContent("spotify_user", "pop")
+    if err == nil {
+        songs := spotifyResults.GetSongs()
+        fmt.Printf("Spotify: %d songs\n", len(songs))
+    }
+}
+```
+
+### 4. Implement User-Friendly Interfaces
+
+```go
+func userFriendlySearch(soundtouch *client.Client, searchTerm string) {
+    fmt.Printf("🔍 Searching for '%s'...\n", searchTerm)
+    
+    results, err := soundtouch.SearchTuneInStations(searchTerm)
+    if err != nil {
+        fmt.Printf("❌ Search failed: %v\n", err)
+        return
+    }
+    
+    if results.IsEmpty() {
+        fmt.Printf("😞 No results found for '%s'\n", searchTerm)
+        fmt.Println("💡 Try different search terms like:")
+        fmt.Println("   - Genre names: jazz, rock, classical")
+        fmt.Println("   - Artist names: Beatles, Mozart")
+        fmt.Println("   - Station types: news, talk, music")
+        return
+    }
+    
+    stations := results.GetStations()
+    fmt.Printf("🎵 Found %d stations:\n", len(stations))
+    
+    for i, station := range stations {
+        fmt.Printf("%d. 📻 %s", i+1, station.GetDisplayName())
+        if station.Description != "" {
+            fmt.Printf("\n   %s", station.Description)
+        }
+        if station.GetArtworkURL() != "" {
+            fmt.Printf("\n   🎨 %s", station.GetArtworkURL())
+        }
+        fmt.Println()
+    }
+}
+```
+
+### 5. Performance Considerations
+
+```go
+func efficientBrowsing(soundtouch *client.Client) {
+    // Use reasonable page sizes
+    const optimalPageSize = 25 // Good balance of network efficiency and memory usage
+    
+    // Cache frequently accessed data
+    var cachedSources *models.Sources
+    
+    getSources := func() (*models.Sources, error) {
+        if cachedSources == nil {
+            var err error
+            cachedSources, err = soundtouch.GetSources()
+            return cachedSources, err
+        }
+        return cachedSources, nil
+    }
+    
+    // Use the cached sources
+    sources, err := getSources()
+    if err != nil {
+        return
+    }
+    
+    // Process efficiently
+    for _, source := range sources.SourceItem {
+        if source.Status.IsReady() {
+            // Only browse ready sources
+            procesReadySource(soundtouch, source.Source, source.SourceAccount)
+        }
+    }
+}
+```

+### Overview of Recent Improvements and Next Steps
+
+This document summarizes the improvements made to the **Marge service** to improve parity with the upstream Bose SoundTouch service, along with open issues and proposed next steps.
+
+#### ✅ Completed Improvements (Marge Service)
+*   **Mapped Preset `buttonNumber`**: Correctly mapped the internal `ServicePreset.ID` or `ButtonNumber` to the `buttonNumber` XML attribute in the `/full` response and ensured it is persisted in the local datastore.
+*   **High-Fidelity Device Metadata**: Improved the datastore to correctly extract, persist, and report detailed device `<components>` (e.g., `LIGHTSWITCH`, `SMSC`) and their firmware versions from upstream responses.
+*   **Standardized Preferred Language**: Updated the default `preferredLanguage` to `de` in the `/full` response and added synchronization to persist it from upstream responses.
+*   **Persisted Provider Settings**: Added support for persisting and echoing back `providerSettings` (e.g., `STREAMING_QUALITY`, `ELIGIBLE_FOR_TRIAL`) from the `/full` response.
+*   **Populated `contentItemType`**: The `contentItemType` (e.g., `tracklisturl`) is now correctly synchronized from upstream, persisted in the local datastore, and returned in the `/full` response for both presets and recents.
+*   **Standardized Credential Types**: Adjusted the logic for Spotify to use the correct `token_version_3` type when a token is present in the `/full` response, improving parity with the upstream service. The service now respects existing `credential_type` values from `Sources.xml` (e.g., `token_version_3` for Spotify) while providing sensible defaults for new or incomplete sources.
+*   **Structured Sources (Sources.xml)**: Refactored `Sources.xml` to use an attribute-based structure (`sourceid`, `source`, `status`, `sourceAccount`, etc.) matching the real device's output. Removed redundant nested tags like `<sourcename>`, `<username>`, and `<name>`.
+*   **Nested Recents (Recents.xml)**: Implemented a nested `<contentItem>` structure within `<recent>` entries in `Recents.xml`, maintaining exact parity with the device's persistence format while supporting legacy flat formats for backward compatibility.
+*   **Inconsistent `serialNumber` Casing**: Fixed the casing mismatch in the `/full` response where the upstream uses camelCase `<serialNumber>` in the top-level `<device>` and lowercase `<serialnumber>` in the nested `<attachedProduct>`. Local responses now correctly mirror this inconsistency.
+*   **Attribute-level Parity**:
+    *   Ensured `sourceAccount=""` is preserved in XML even when empty, matching device behavior for sources like TUNEIN.
+    *   Fixed casing for attributes like `deviceID` and `utcTime` in `Recents.xml`.
+    *   Correctly mapped and persisted preset and recent `id` attributes during "Initial Data Sync".
+*   **Device Name Consistency**: Fixed an issue where the device `<name>` was empty in some local `/full` responses by ensuring it is correctly populated from the datastore and synchronized from upstream.
+*   **Improved XML Parity**: Empty `<name>` tags in the `/full` response are now self-closing (`<name/>`), matching upstream behavior.
+*   **Timestamp-based ID Generation**: Implemented a 9-digit ID schema (`YYMMDD` + 3-digit counter) for `recent` items, ensuring IDs are large, unique, and stay within the 32-bit integer range.
+*   **Automatic Source Learning**: The service now extracts and persists full metadata (credentials, provider IDs, and custom names) from incoming `POST /recent` requests. This improves parity for subsequent `GET /recents` calls.
+*   **Source Provider Mapping**: Synchronized local source provider IDs and timestamps with upstream data. The `RADIO_BROWSER` provider is included in the public `/streaming/sourceproviders` list to maintain internal functionality while acknowledging it as a parity gap.
+*   **Credential Preservation**: Improved `AddRecent` to correctly extract and echo back base64 tokens/credentials provided in the incoming request, improving source learning.
+*   **XML Formatting Parity**:
+    *   Added `standalone="yes"` to the XML declaration for all Marge responses, including `recent`, `presets`, `full account`, `software update`, and `sourceproviders`.
+    *   Enforced self-closing `<sourceSettings/>` tags for parity.
+    *   Standardized date formatting to UTC with milliseconds (`.000+00:00`).
+    *   Fixed casing for `/streaming/sourceproviders`: Root element is `<sourceProviders>`, but child elements are `<sourceprovider>` (all lowercase), matching upstream behavior.
+    *   Implemented structured XML marshaling with consistent 2-space indentation for recents and source providers.
+*   **Improved TuneIn Parity**: Fixed TuneIn source mapping to use ID `25` and ensuring `sourcename` is empty in responses, matching upstream behavior for station playback.
+*   **High-Fidelity Full Account Sync**: Refactored the `/streaming/account/{accountId}/full` response to match the upstream structure. This includes:
+    *   **Mapped Preset `buttonNumber`**: Correctly mapped the internal `ServicePreset.ID` to the `buttonNumber` XML attribute in the `/full` response.
+    *   **Structured XML Marshaling**: Replaced manual string concatenation with structured Go models and `xml.Marshal` for the entire response.
+    *   **Specific Response Models**: Introduced `FullResponseSource`, `FullResponsePreset`, and `FullResponseRecent` to accurately reflect the upstream structure where `<source>` is a child element, rather than a set of attributes.
+    *   **Correct Nesting**: Ensured that `<presets>` and `<recents>` correctly nest their associated `<source>` details, resolving previous data omissions.
+    *   **Device Identity**: Added `<serialNumber>` and `<updatedOn>` to both the top-level `<device>` and its `<attachedProduct>`, ensuring consistent device identification.
+    *   **Field-Level Parity**: Mapped missing fields like `<contentItemType>` and `<productlabel>` to match upstream expectations.
+    *   **Improved Source Matching**: Enhanced internal logic to correctly link presets and recents to their configured sources based on multiple identifiers (ID, Key, or Type).
+*   **Verified Parity Mismatch Fixes**: Comprehensive reproduction tests (`TestParityMismatchReproduction_V2` and `TestParityMismatchReproduction_V3`) now confirm parity for identified mismatches in `POST /recent` and `GET /recents`, including credentials and source-specific metadata.
+*   **Unified Response Logic**: Refactored the code so that both `POST /recent` and `GET /recents` use the same formatting functions, guaranteeing consistency.
+*   **Robust Parity Detection**: Updated the local parity checker to be whitespace-insensitive for XML bodies, significantly reducing noise from minor indentation or newline differences.
+*   **Maintainable XML Generation**: Reduced cyclomatic complexity and code duplication in `marge.go` by extracting focused helper functions for mapping internal data to response-specific XML models.
+
+---
+
+#### 🛠️ Open Issues and Next Steps
+
+Based on the latest `parity_mismatches` and the high-fidelity `/full` account response comparison (diff14), here are the recommended areas for further work:
+
+#### 1. BMX / TuneIn Playback Parity (Medium)
+Current mismatches in `/bmx/tunein/v1/playback/station/...` show differences in reporting URLs and missing links:
+*   **Mismatched Parameters**: Local reporting URLs use `listen_id=1234567890`, while upstream uses a different session-based ID.
+*   **Missing Links**: Some upstream responses include additional `_links` or metadata that are currently omitted in local responses.
+*   **Action**: Improve the `HandleTuneInPlayback` logic to better mirror the upstream response structure and parameter generation.
+
+#### 2. `/full` Account Response Data Gaps (Medium)
+While structural parity for the `/full` response is high, several value-level gaps remain as shown in `diff14`:
+*   **Timestamp Formats**: Upstream uses ISO-8601 with milliseconds (e.g., `2024-06-23T07:40:36.000+00:00`), whereas some local fields still use Unix epoch integers (e.g., `1234567890`).
+*   **Provider Settings**: The `providerSettings` block in the local response currently lacks crucial values like `keyName`, `providerId`, and `boseId` (appearing as empty tags).
+*   **Component Metadata**: Local component types are sometimes empty (`type=""`) compared to upstream values like `LIGHTSWITCH` or `SMSC`.
+*   **Source/Preset Identifiers**: Local IDs (e.g., `100004`) differ from upstream IDs (e.g., `1234567`), though this may be expected due to different account/device environments.
+*   **Action**: Update the mapping logic in `marge.go` and `setup.go` to ensure all fields in the `/full` response are correctly populated with high-fidelity values and standard ISO-8601 timestamps.
+
+#### 3. OAuth / Spotify Token Noise (Low/Medium)
+The `/oauth/device/.../token` endpoint frequently reports mismatches because tokens are naturally different between local and upstream.
+*   **The Issue**: This creates "noise" in your parity reports that isn't actually a bug.
+*   **Action**: Update the parity detection logic (or the handler) to selectively ignore the `access_token` field while still verifying that the rest of the JSON structure (expires_in, scope, token_type) matches.
+
+#### 4. Large IDs for Other Models (Medium)
+While we fixed IDs for `recents`, other models like `presets` or `sources` might still use small auto-incrementing integers.
+*   **Action**: Evaluate if other endpoints should also transition to the timestamp-based ID schema to further reduce diff noise.
+
+#### 5. Improved Data Persistence (Continuous)
+Continue the "learning" approach for other services. For example, if we see a new `sourceproviderid` in a Spotify or TuneIn request, we should ensure it is stored and reused.
+
+#### 6. Local Reboot & Device State Management (Continuous)
+Analysis of device reboot logs revealed several data requirements:
+*   **Power-On Details Tracking**: Implemented extraction and persistence of detailed device information (serial numbers, firmware version, product details, and MAC addresses) from the `POST /streaming/support/power_on` request. This data is now stored in the local datastore, improving our ability to respond accurately to subsequent management requests.
+*   **Source Provider Mapping**: Synchronized local source provider IDs and timestamps with upstream data. The `RADIO_BROWSER` provider is included in the public `/streaming/sourceproviders` list to maintain internal functionality while acknowledging it as a parity gap.
+
+#### 7. Account Full Response (/full) Structural & Value Parity (Completed)
+Structural and value gaps in the `/full` account response have been addressed:
+
+**Key Fixes:**
+*   **Structural**:
+    *   **Nested Source Association**: Improved the matching logic in `mapRecentsToFullResponse` to correctly link recents to their specific `ConfiguredSource` (e.g., by matching `sourceid` attribute).
+    *   **XML Tag Formatting**: Standardized self-closing tags and element formatting to match upstream's multi-line or empty-element formatting in various contexts.

+# Parity Analysis: Bose-SoundTouch (Go) vs. OpenCloudTouch (Python)
+
+This document provides a comparative analysis of the current Go implementation and the `scheilch/opencloudtouch` project, identifying functional gaps and potential improvements.
+
+## 1. Core Architecture and Language
+- **Bose-SoundTouch (Go)**: A high-performance, strongly typed backend with a CLI and background service. Focuses on full API coverage, parity testing, and robust hardware control (DSP, zones).
+- **OpenCloudTouch (OCT)**: A modern full-stack application (FastAPI + React/TypeScript). Prioritizes user experience with a web-based setup wizard and a clean abstraction for internet radio.
+
+## 2. Functional Comparison
+
+| Feature                 | Bose-SoundTouch (Go)                                       | OpenCloudTouch (Python)                                                 |
+|:------------------------|:-----------------------------------------------------------|:------------------------------------------------------------------------|
+| **Setup Experience**    | CLI-driven or manual API calls for migration (SSH, XML).   | Web-based **Setup Wizard** guides through SSH, backup, and redirection. |
+| **Radio Support**       | Static integration of **RadioBrowser** and TuneIn.         | Dynamic **RadioBrowserAdapter** with automatic **API Failover**.        |
+| **Commercial Services** | Deep integration (Spotify priming, Pandora, Deezer, etc.). | Basic support, focus is on local content and radio.                     |
+| **Hardware Control**    | Extensive (Bass, Treble, Soundbar levels, Clock display).  | Basic playback and zone controls.                                       |
+| **Cloud Emulation**     | High-fidelity parity (mirroring, discrepancy logging).     | Functional emulation for local preset/recent persistence.               |
+| **Notifications**       | Built-in **TTS** and custom URL audio alerts.              | Not a primary focus.                                                    |
+
+## 3. Key Strengths of OpenCloudTouch
+- **Guided Onboarding**: The setup wizard reduces the entry barrier for non-technical users significantly.
+- **Resilient Radio**: The API failover for RadioBrowser ensures continuous service even if specific community-hosted API instances go offline.
+- **Modern API Stack**: Uses OpenAPI and generated TypeScript types for a seamless frontend integration.
+- **Provider Abstraction**: A cleaner internal separation between the "Bose World" (XML/BMX) and external content providers (RadioBrowser).

+## 4. Suggested Improvements for Bose-SoundTouch
+
+### A. Web-based Setup Wizard (High Priority)
+- Implement a state-driven wizard in the `soundtouch-service` to handle:
+  - SSH activation (checking `/remote_services` via USB).
+  - Automated backup of speaker configuration.
+  - Verification of DNS/Hosts redirection.
+- Expose this via a simple embedded Web UI (using Go's `embed` package).
+
+### B. RadioBrowser Failover (Medium Priority)
+- Adapt the failover logic from OCT:
+  - Periodically refresh the list of available RadioBrowser API servers.
+  - Implement a retry mechanism that switches servers on 5xx errors or timeouts.
+
+### C. External Service Abstraction (Medium Priority)
+- Refactor the hardcoded BMX logic into a more modular **Provider System** (see `EXTERNAL-SERVICES-ABSTRACTION.md`).
+- This will allow easier addition of new sources (e.g., local DLNA, generic M3U playlists) without touching the core BMX handlers.
+
+## 5. Summary
+While our Go project provides the most complete technical coverage of SoundTouch hardware and commercial services, OpenCloudTouch sets a higher standard for **user onboarding** and **service resilience** for community-driven content. Integrating a setup wizard and a more robust radio backend would make our project significantly more accessible and reliable.

+# Parity Analysis: Bose-SoundTouch (Go) vs. SoundCork (Python)
+
+This document provides a comparative analysis of the current Go implementation and the `deborahgu/soundcork` project, identifying functional gaps and potential improvements.
+
+## 1. Core Architecture and Language
+- **Bose-SoundTouch (Go)**: Uses `chi` for routing and `encoding/xml` for data. High performance, strong typing, and precise MIME type handling (`application/vnd.bose.streaming-v1.2+xml`).
+- **SoundCork (Python)**: Uses `FastAPI` and `xml.etree.ElementTree`. Prioritizes flexibility and rapid prototyping of streaming service mocks.
+
+## 2. Functional Comparison
+
+| Feature              | Bose-SoundTouch (Go)                                                                                                  | SoundCork (Python)                                                                      |
+|:---------------------|:----------------------------------------------------------------------------------------------------------------------|:----------------------------------------------------------------------------------------|
+| **Group Management** | Full CRUD: `POST /group`, `POST /group/{id}`, `DELETE /group/{id}` with XML datastore persistence (`Group_{id}.xml`). | Active group management (`groups.py`), supporting `/addGroup` and stereo pairing logic. |
+| **ZeroConf Priming** | Full DH key exchange + encrypted blob; fallback to `tokenType=accesstoken` for older firmware.                        | Simple `tokenType=accesstoken` push only; token expires after ~60 minutes.              |
+| **BMX Services**     | Supports TuneIn, Orion, and custom streams.                                                                           | More modular `bmx_services.json` registry with broader mock support.                    |
+| **Persistence**      | Mixed JSON/XML datastore.                                                                                             | Pure XML-based persistence per device/account.                                          |
+| **Admin UI**         | CLI-based (`soundtouch-cli`) or API-driven.                                                                           | Draft Web UI for device discovery and account management (`admin.py`).                  |
+| **Discovery**        | Integrated setup tools and SSDP/MDNS awareness.                                                                       | Leverages `bosesoundtouchapi` Python library for active discovery.                      |
+
+## 3. Key Strengths of SoundCork
+- **Group Pairing Logic**: Includes logic to manage master/slave relationships for SoundTouch 10 stereo pairs.
+- **Service Extensibility**: JSON-based registry for BMX services makes it easier to mock multiple providers (SiriusXM, Spotify) without code changes.
+- ~~**Mock Coverage**: Better coverage of "dummy" endpoints that respond with plausible XML (e.g., `customerSupport`).~~ **Addressed**: AfterTouch's `HandleNotFound` (registered via `r.NotFound`) logs every unimplemented endpoint as `[UNHANDLED]` and forwards the request to the Bose upstream via `HandleBoseProxy`. This provides at least the same coverage as static dummy responses, while also aiding discovery of new endpoints.
+
+## 4. Suggested Implementation Steps for Bose-SoundTouch
+
+### ✅ A. Implement Full Group Support (Completed)
+- `POST /group`, `POST /group/{id}`, `DELETE /group/{id}` implemented in `pkg/service/handlers/handlers_marge.go`.
+- Group CRUD persisted in XML datastore (`Group_{id}.xml`) via `pkg/service/datastore/datastore.go`.
+- `GET /group` on device registration reads the group the device belongs to.
+
+### ✅ B. Proper ZeroConf Spotify Blob (Completed)
+- Full Spotify Connect ZeroConf protocol implemented in `pkg/service/spotify/zeroconf.go`.
+- Flow: `getInfo` (fetch speaker DH public key) → 768-bit DH key exchange → AES-128-CTR encrypted `LoginCredentials` protobuf blob → `addUser`.
+- Speaker can self-refresh credentials independently; no periodic re-priming needed for token expiry.
+- Automatic fallback to `tokenType=accesstoken` if `getInfo` fails (older firmware without DH support).
+- See `docs/concepts/spotify-priming-strategy.md` for full protocol details.
+- **Remaining gap**: Background watchdog to re-prime devices that lose their session (reboot / power loss). Not required for token expiry on modern firmware; only needed for the "speaker rebooted and lost state" recovery path and for older firmware on the fallback path (~45 min token expiry).
+
+### C. Modularize BMX Registry (Medium Priority)
+- Extract the hardcoded service list in `HandleBMXRegistry` into an external `bmx-services.json` file.
+- Allow users to customize which mocked services are advertised to the speaker.
+
+### D. Enhanced Source Management (Medium Priority)
+- Refine source learning logic to ensure all `sourceAccount` and `sourceName` metadata is correctly captured during synchronization, using patterns from `soundcork`'s `learnSource`.
+
+### E. Basic Admin Web UI (Low Priority)
+- Develop a minimal internal status page to list active accounts and connected devices, improving usability over raw API calls.
+
+## 5. Summary
+
+Group support and ZeroConf Spotify priming are now feature-complete in AfterTouch. The Go implementation is structurally more consistent with recent reference recordings (e.g., `buttonNumber`, detailed `components`). SoundCork's remaining functional advantages are:
+
+- **BMX service extensibility**: the `bmx_services.json` registry makes it trivial to add or mock new streaming providers without code changes (step C above).
+- **Group pairing logic**: master/slave relationship management for SoundTouch 10 stereo pairs goes beyond the CRUD AfterTouch implements.
+
+For the broader ecosystem context (feature matrix across all community projects, AfterTouch open tasks, and cross-project observations) see [docs/analysis/bose-soundtouch-community-tools.md](analysis/bose-soundtouch-community-tools.md).

+# Preset Management Quick Start Guide
+
+**Save your favorite music, radio stations, and playlists as 1-6 presets for instant access.**
+
+## Overview
+
+SoundTouch devices support 6 preset slots that can store your favorite content for instant access. This guide shows you how to manage presets using both the CLI and Go library.
+
+## Quick CLI Usage
+
+### 1. See Current Presets
+```bash
+soundtouch-cli --host 192.168.1.100 preset list
+```
+
+### 2. Store What's Currently Playing
+```bash
+# Store current song/station as preset 1
+soundtouch-cli --host 192.168.1.100 preset store-current --slot 1
+```
+
+### 3. Store Specific Content
+
+#### Spotify Playlist
+```bash
+soundtouch-cli --host 192.168.1.100 preset store \
+  --slot 2 \
+  --source SPOTIFY \
+  --location "spotify:playlist:37i9dQZF1DXcBWIGoYBM5M" \
+  --name "Today's Top Hits"
+```
+
+#### Radio Station
+```bash
+soundtouch-cli --host 192.168.1.100 preset store \
+  --slot 3 \
+  --source TUNEIN \
+  --location "/v1/playbook/station/s33828" \
+  --name "K-LOVE Radio"
+```
+
+### 4. Use Your Presets
+```bash
+# Play preset 1
+soundtouch-cli --host 192.168.1.100 preset select --slot 1
+
+# Play preset 2
+soundtouch-cli --host 192.168.1.100 preset select --slot 2
+```
+
+### 5. Remove Presets
+```bash
+# Remove preset 6
+soundtouch-cli --host 192.168.1.100 preset remove --slot 6
+```
+
+## Getting Content Locations
+
+To store specific content, you need the `location` parameter. Here's how to get it:
+
+### Method 1: From Currently Playing Content
+```bash
+# Play the content you want to save, then:
+soundtouch-cli --host 192.168.1.100 play now
+```
+
+**Example output:**
+```
+Now Playing:
+  Track: Bohemian Rhapsody
+  Artist: Queen
+  Source: SPOTIFY
+
+Content Details:
+  Location: spotify:track:17GmwQ9Q3MTAz05OokmNNB  ← Use this!
+```
+
+### Method 2: Convert Spotify URLs
+If you have a Spotify web URL, convert it to a URI:
+
+- **URL**: `https://open.spotify.com/playlist/37i9dQZF1DXcBWIGoYBM5M`
+- **URI**: `spotify:playlist:37i9dQZF1DXcBWIGoYBM5M`
+
+Just replace `https://open.spotify.com/` with `spotify:` and `/` with `:`.
+
+## Common Content Types
+
+### Spotify Content
+```bash
+# Playlist
+--source SPOTIFY --location "spotify:playlist:37i9dQZF1DXcBWIGoYBM5M"
+
+# Album
+--source SPOTIFY --location "spotify:album:4aawyAB9vmqN3uQ7FjRGTy"
+
+# Artist
+--source SPOTIFY --location "spotify:artist:6APm8EjxOHSYM5B4i3vT3q"
+
+# Track
+--source SPOTIFY --location "spotify:track:17GmwQ9Q3MTAz05OokmNNB"
+```
+
+### Radio Stations
+```bash
+# TuneIn Radio
+--source TUNEIN --location "/v1/playbook/station/s33828"
+
+# Internet Radio Stream
+--source LOCAL_INTERNET_RADIO --location "https://stream.example.com/jazz"
+```
+
+### Local Music (NAS/USB)
+```bash
+# Album from local storage
+--source STORED_MUSIC --location "album:983"
+
+# Track from local storage  
+--source STORED_MUSIC --location "track:2579"
+```
+
+## Go Library Usage
+
+### Basic Operations
+```go
+package main
+
+import (
+    "fmt"
+    "log"
+    
+    "github.com/gesellix/bose-soundtouch/pkg/client"
+    "github.com/gesellix/bose-soundtouch/pkg/models"
+)
+
+func main() {
+    // Create client
+    c := client.NewClient(&client.Config{
+        Host: "192.168.1.100",
+        Port: 8090,
+    })
+    
+    // List current presets
+    presets, err := c.GetPresets()
+    if err != nil {
+        log.Fatal(err)
+    }
+    fmt.Printf("Found %d presets\n", len(presets.Preset))
+    
+    // Store current content as preset 1
+    err = c.StoreCurrentAsPreset(1)
+    if err != nil {
+        log.Fatal(err)
+    }
+    
+    // Store Spotify playlist as preset 2
+    content := &models.ContentItem{
+        Source:        "SPOTIFY",
+        Type:          "uri",
+        Location:      "spotify:playlist:37i9dQZF1DXcBWIGoYBM5M",
+        SourceAccount: "username",
+        IsPresetable:  true,
+        ItemName:      "My Favorites",
+    }
+    err = c.StorePreset(2, content)
+    if err != nil {
+        log.Fatal(err)
+    }
+    
+    // Select preset 1
+    err = c.SelectPreset(1)
+    if err != nil {
+        log.Fatal(err)
+    }
+}
+```
+
+### Smart Preset Management
+```go
+// Find next available slot automatically
+nextSlot, err := c.GetNextAvailablePresetSlot()
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Next available slot: %d\n", nextSlot)
+
+// Check if current content can be saved
+presetable, err := c.IsCurrentContentPresetable()
+if err != nil {
+    log.Fatal(err)
+}
+if presetable {
+    c.StoreCurrentAsPreset(nextSlot)
+}
+
+// Get preset by ID
+presets, _ := c.GetPresets()
+preset := presets.GetPresetByID(1)
+if preset != nil && !preset.IsEmpty() {
+    fmt.Printf("Preset 1: %s\n", preset.GetDisplayName())
+}
+```
+
+## Real-Time Preset Events
+
+Monitor preset changes in real-time using WebSocket events:
+
+```go
+// Create WebSocket client
+wsClient := c.NewWebSocketClient(nil)
+
+// Handle preset updates
+wsClient.OnPresetUpdated(func(event *models.PresetUpdatedEvent) {
+    fmt.Printf("Presets updated on device %s\n", event.DeviceID)
+    for _, preset := range event.Presets.Preset {
+        if !preset.IsEmpty() {
+            fmt.Printf("  Preset %d: %s (%s)\n", 
+                preset.ID, preset.GetDisplayName(), preset.GetSource())
+        }
+    }
+})
+
+// Connect and listen
+err := wsClient.Connect()
+if err != nil {
+    log.Fatal(err)
+}
+defer wsClient.Close()
+
+// Keep listening for events
+select {} // Run forever
+```
+
+## Practical Examples
+
+### Family Setup
+```bash
+# Dad's morning playlist
+soundtouch-cli --host 192.168.1.100 preset store \
+  --slot 1 --source SPOTIFY \
+  --location "spotify:playlist:morning-energy" \
+  --name "Dad's Morning Mix"
+
+# Mom's cooking music
+soundtouch-cli --host 192.168.1.100 preset store \
+  --slot 2 --source SPOTIFY \
+  --location "spotify:playlist:cooking-vibes" \
+  --name "Kitchen Tunes"
+
+# Kids' bedtime stories
+soundtouch-cli --host 192.168.1.100 preset store \
+  --slot 3 --source TUNEIN \
+  --location "/v1/playbook/station/bedtime-stories" \
+  --name "Bedtime Stories"
+```
+
+### Party Mode
+```bash
+# Upbeat party playlist
+soundtouch-cli --host 192.168.1.100 preset store-current --slot 1
+
+# Chill background music  
+soundtouch-cli --host 192.168.1.100 preset store-current --slot 2
+
+# Dance music
+soundtouch-cli --host 192.168.1.100 preset store-current --slot 3
+```
+
+### Smart Home Integration
+```bash
+# Morning routine (preset 1) - triggered by smart home at 7 AM
+soundtouch-cli --host 192.168.1.100 preset select --slot 1
+
+# Evening routine (preset 2) - triggered at sunset
+soundtouch-cli --host 192.168.1.100 preset select --slot 2
+```
+
+## Troubleshooting
+
+### "Content is not presetable"
+Not all content can be saved as presets:
+- ✅ **Works**: Spotify, TuneIn, Internet Radio, Local Music
+- ❌ **Doesn't work**: Bluetooth, AUX, AirPlay (live sources)
+
+**Solution**: Switch to a supported source first.
+
+### "All preset slots are occupied"
+```bash
+# See which presets you have
+soundtouch-cli --host 192.168.1.100 preset list
+
+# Remove one you don't need
+soundtouch-cli --host 192.168.1.100 preset remove --slot 6
+
+# Or overwrite an existing one
+soundtouch-cli --host 192.168.1.100 preset store-current --slot 6
+```
+
+### Getting Spotify URIs
+If you can't find Spotify URIs:
+
+1. **Play the content** in Spotify on your SoundTouch
+2. **Check what's playing**: `soundtouch-cli --host 192.168.1.100 play now`
+3. **Copy the location** from the output
+
+### Device Connection Issues
+```bash
+# Test connection first
+soundtouch-cli --host 192.168.1.100 info
+
+# If that fails, check:
+# - Device IP address is correct
+# - Device is powered on
+# - Network connectivity
+```
+
+## Best Practices
+
+### Preset Organization
+- **Slot 1-2**: Daily favorites (morning playlist, news)
+- **Slot 3-4**: Mood music (workout, relaxation)  
+- **Slot 5-6**: Special content (party music, kids' content)
+
+### Content Management
+- Use descriptive `--name` parameters for easy identification
+- Store both individual tracks and playlists for variety
+- Keep at least one slot free for temporary content
+
+### Automation Ideas
+- Create shell scripts for common preset operations
+- Use with smart home systems for scheduled music
+- Integrate with calendar events (work music during work hours)

+# Request Recording Concept
+
+## Problem Statement
+
+The current request recording system has fundamental issues when dealing with request cloning, body consumption, and multiple response scenarios. Specifically:
+
+1. **Body Consumption**: HTTP request bodies can only be read once, leading to missing bodies in recordings
+2. **Request Cloning**: A single original request may be cloned multiple times for different purposes (local handling, mirroring, recording)
+3. **Multiple Responses**: The same logical request may generate different responses (local vs upstream mirror)
+4. **Data Integrity**: No guarantee that recorded requests are identical across different execution paths
+
+## Current Issues (Examples)
+
+### Issue 1: Missing Request Bodies in Mirror Recordings

+    // Response: 200 OK
+    // Headers:
+    // X-Proxy-Origin: upstream-mirror
+%}
+{% endraw %}
+```
+
+### Issue 2: Request Flow Complexity
+
+Current middleware execution order:
+```
+1. MirrorMiddleware    - Buffers body, creates clones
+2. RecordMiddleware    - Also buffers body
+3. Application Handler - Processes request
+4. Mirror Execution    - Async/sync mirror to upstream
+5. Recording           - Multiple recording points
+```
+
+Problems:
+- Multiple body reads across middleware chain
+- Inconsistent request state between clones
+- Race conditions in async scenarios
+- No guarantee of request equivalence
+
+## Proposed Solution: Context-Bound Request Snapshots
+
+### Core Concept
+
+Create **immutable request snapshots** early in the request lifecycle and propagate them through the **Request Context**. This ensures all downstream consumers (Mirroring, Recording, Parity Check) use identical data without re-reading the request body.
+
+### Architecture (Context-Only)
+

+      └────────┘ └─────────┘ └──────────────┘
+```
+
+### Request Snapshot Structure
+
+```go
+type RequestSnapshot struct {
+    Method    string
+    URL       *url.URL
+    Headers   http.Header
+    Body      []byte
+    Host      string
+    Timestamp time.Time
+}
+
+// Typed key for context safety
+type contextKey struct{ name string }
+var SnapshotKey = &contextKey{"request_snapshot"}
+```
+
+### Implementation Strategy
+
+#### Phase 1: Snapshot Middleware
+
+```go
+func (s *Server) SnapshotMiddleware(next http.Handler) http.Handler {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        // 1. Capture body once with size limit (e.g. 2MB)
+        body, _ := io.ReadAll(io.LimitReader(r.Body, 2*1024*1024))
+        r.Body.Close()
+
+        // 2. Create snapshot
+        snapshot := &RequestSnapshot{
+            Method:    r.Method,
+            URL:       cloneURL(r.URL),
+            Headers:   r.Header.Clone(),
+            Body:      body,
+            Host:      r.Host,
+            Timestamp: time.Now(),
+        }
+
+        // 3. Inject pointer into context
+        ctx := context.WithValue(r.Context(), SnapshotKey, snapshot)
+
+        // 4. Restore r.Body for downstream compatibility
+        r = r.WithContext(ctx)
+        r.Body = io.NopCloser(bytes.NewReader(snapshot.Body))
+
+        next.ServeHTTP(w, r)
+    })
+}
+```
+
+#### Phase 2: Downstream Consumption
+
+Consumers (Mirror/Record) retrieve the snapshot directly from context:
+
+```go
+snapshot, ok := r.Context().Value(SnapshotKey).(*RequestSnapshot)
+if ok {
+    // Use snapshot.Body directly instead of io.ReadAll(r.Body)
+}
+```
+
+## Hardware Considerations (Raspberry Pi Zero 2W)
+
+To protect MicroSD health and optimize for limited memory:
+
+1. **No Intermediate Disk Storage**: Snapshots exist only in memory; they are never written to disk until the final `.http` recording is generated.
+2. **Memory Management**: Use `sync.Pool` for temporary buffers to reduce GC churn on the single-core/low-memory SoC.
+3. **Automatic Cleanup**: Snapshots are naturally garbage collected once the Request Context and all child goroutines (detached mirrors/recordings) finish.
+4. **Body Capping**: Strict limits on snapshot size prevent OOM (Out-of-Memory) conditions.
+
+#### Phase 2: Response Capture System
+
+```go
+type ResponseRecorder struct {
+    http.ResponseWriter
+    snapshot     *ResponseSnapshot
+    snapshotID   string
+    source       string
+    startTime    time.Time
+}
+
+func (r *ResponseRecorder) WriteHeader(statusCode int) {
+    r.snapshot.StatusCode = statusCode
+    r.snapshot.Headers = r.Header().Clone()
+    r.ResponseWriter.WriteHeader(statusCode)
+}
+
+func (r *ResponseRecorder) Write(data []byte) (int, error) {
+    r.snapshot.Body = append(r.snapshot.Body, data...)
+    return r.ResponseWriter.Write(data)
+}
+
+func (r *ResponseRecorder) finalize() {
+    r.snapshot.Duration = time.Since(r.startTime)
+    r.snapshot.Timestamp = time.Now()
+}
+```
+
+#### Phase 3: Recording System Integration
+
+```go
+type RecordingManager struct {
+    storage   SnapshotStorage
+    recorder  *Recorder
+    patterns  []string
+}
+
+func (rm *RecordingManager) RecordInteraction(snapshotID string, response *ResponseSnapshot) {
+    // Retrieve immutable request snapshot
+    request, exists := rm.storage.Get(snapshotID)
+    if !exists {
+        log.Printf("Request snapshot not found: %s", snapshotID)
+        return
+    }
+
+    // Record with guaranteed data integrity
+    rm.recorder.RecordInteraction(request, response)
+}
+
+func (r *Recorder) RecordInteraction(req *RequestSnapshot, res *ResponseSnapshot) error {
+    // Generate .http file with complete data
+    var buf bytes.Buffer
+
+    // Write request
+    fmt.Fprintf(&buf, "### %s %s\n", req.Method, req.URL.String())
+    fmt.Fprintf(&buf, "%s %s\n", req.Method, req.URL.String())
+    fmt.Fprintf(&buf, "Host: %s\n", req.Host)
+
+    for k, vv := range req.Headers {
+        for _, v := range vv {
+            fmt.Fprintf(&buf, "%s: %s\n", k, v)
+        }
+    }
+
+    buf.WriteString("\n")
+    buf.Write(req.Body)
+    buf.WriteString("\n\n")
+
+    // Write response
+{% raw %}
+    buf.WriteString("> {% \n")
+{% endraw %}
+    fmt.Fprintf(&buf, "    // Response: %d %s\n", res.StatusCode, http.StatusText(res.StatusCode))
+    buf.WriteString("    // Headers:\n")
+
+    for k, vv := range res.Headers {
+        for _, v := range vv {
+            fmt.Fprintf(&buf, "    // %s: %s\n", k, v)
+        }
+    }
+
+{% raw %}
+    buf.WriteString("%}\n\n")
+{% endraw %}
+
+    if len(res.Body) > 0 {
+        buf.WriteString("/*\n")
+        buf.Write(res.Body)
+        buf.WriteString("\n*/\n")
+    } else {
+        buf.WriteString("// [Binary response body: 0 bytes]\n")
+    }
+
+    // Write to file
+    return r.writeToFile(buf.Bytes(), req, res)
+}
+```
+
+## Migration Strategy
+
+### Phase 1: Introduce Snapshot System
+- Add SnapshotMiddleware as first middleware
+- Maintain existing recording system for compatibility
+- Gradual migration of recording points
+
+### Phase 2: Update Mirror System
+- Modify MirrorMiddleware to use snapshots
+- Ensure mirror requests use snapshot data
+- Test parity between old and new systems
+
+### Phase 3: Consolidate Recording
+- Replace existing recording middleware
+- Unified recording system using context-bound snapshots
+- Remove duplicate body reading code
+
+### Phase 4: Cleanup
+- Remove legacy recording code
+- Optimize memory usage with sync.Pool
+- Performance validation on target hardware (Pi Zero)
+
+## Benefits
+
+1. **Zero Extra Disk IO**: Protecs MicroSD by avoiding snapshot disk persistence
+2. **Memory Efficiency**: Natural lifecycle tied to Request Context
+3. **Data Integrity**: Request data is captured once and remains immutable
+4. **Consistency**: All consumers use identical request data
+5. **Traceability**: Clear lineage from original request to all recordings
+6. **Performance**: Reduces duplicate body reads and re-cloning
+
+## Implementation Considerations
+
+### Memory Management
+- Use `sync.Pool` for byte buffers
+- Strict size limits on captured bodies
+- Rely on GC for snapshot cleanup
+
+### Performance Impact
+- Single body read vs multiple reads (net positive)
+- Memory overhead for snapshot storage (manageable)
+- Context propagation overhead (minimal)
+
+### Backward Compatibility
+- Maintain existing .http file format
+- Preserve existing API contracts
+- Gradual migration path
+
+## Testing Strategy
+
+### Unit Tests
+- Snapshot creation and immutability
+- Response recording accuracy
+- Memory cleanup verification
+
+### Integration Tests
+- End-to-end request/response recording
+- Mirror functionality with snapshots
+- Parity validation between old/new systems
+
+### Performance Tests
+- Memory usage comparison
+- Throughput impact analysis
+- Large request body handling
+
+## Future Enhancements
+
+1. **Compression**: Compress stored snapshots for memory efficiency
+2. **Streaming**: Support for streaming request/response bodies
+3. **Filtering**: Selective snapshot creation based on patterns
+4. **Analytics**: Request/response analysis and metrics
+5. **Export**: Snapshot export for debugging and analysis
+
+## Conclusion
+
+This snapshot-based approach provides a robust foundation for reliable request recording while solving the current issues with body consumption and data inconsistency. The phased implementation ensures minimal disruption while delivering immediate benefits.

+# SCMUDC Enrichment Implementation Summary
+
+## Overview
+
+This document summarizes the implementation of SCMUDC (Sound Control Management Usage Data Collection) event enrichment in the AfterTouch toolkit. The enhancement provides human-readable analysis of device telemetry data to improve usability and debugging capabilities.
+
+## Problem Solved
+
+Previously, SCMUDC telemetry events were stored as raw JSON with Base64-encoded XML content, making them difficult to analyze. Users had to manually decode content to understand what device interactions were being recorded.
+
+## Solution Implemented
+
+### 1. Backend Enrichment (`pkg/service/proxy/`)
+
+#### New File: `scmudc.go`
+- **SCMUDCRequest/SCMUDCEvent Structs**: Parse incoming telemetry JSON
+- **EnrichedSCMUDCEvent Struct**: Human-readable analysis with decoded content
+- **DecodedContent Struct**: Parsed XML metadata (track names, artwork URLs, etc.)
+- **enrichSCMUDCRequest()**: Main enrichment function that:
+  - Identifies event origin (app, hardware, or internal system)
+  - Decodes Base64 XML content for device events
+  - Creates human-readable summaries
+- **Helper Functions**: Button formatting, content summarization, origin descriptions
+
+#### Enhanced File: `recorder.go`
+- **Updated save() method**: Extracts SCMUDC data during recording
+- **New writeRequestWithEnrichment()**: Adds enriched comments to .http files
+- **New writeResponseWithEnrichment()**: Includes SCMUDC analysis in response section
+- **Updated Interaction struct**: Added `SCMUDCData` field for API responses
+- **New extractSCMUDCFromFile()**: Parses enrichment data from existing .http files
+- **Enhanced parseInteractionFile()**: Populates SCMUDC data when listing interactions
+
+### 2. Frontend Enhancement
+
+#### Updated HTML (`pkg/service/handlers/web/index.html`)
+- **New Column**: Added "Event Details" to interactions table
+- **Table Structure**: Updated to accommodate SCMUDC enrichment display
+
+#### Enhanced JavaScript (`pkg/service/handlers/web/js/script.js`)
+- **Updated fetchInteractions()**: Displays enriched SCMUDC data with icons
+- **New Helper Functions**:
