 This Go library will continue to work as it uses the local Web API for direct device control, which is unaffected by the cloud service discontinuation. The local preset management functionality implemented in this library (discovered through the [SoundTouch Plus Wiki](https://github.com/thlucas1/homeassistantcomponent_soundtouchplus/wiki/SoundTouch-WebServices-API)) provides an alternative to the cloud-based preset features that will be discontinued.

+# 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
+```
+GET  /                          # SPA - serves static/index.html
+GET  /api/devices              # List all devices (JSON)
+GET  /api/device/{id}          # Get device info (JSON)
+POST /api/discover             # Trigger device discovery
+GET  /api/control/{id}/play    # Playback control
+GET  /api/control/{id}/pause   # Pause playback
+GET  /api/control/{id}/stop    # Stop playback
+GET  /api/control/{id}/next    # Next track
+GET  /api/control/{id}/previous # Previous track
+POST /api/control/{id}/volume  # Set volume (JSON body)
+GET  /api/control/{id}/mute    # Toggle mute
+POST /api/control/{id}/bass    # Set bass level (JSON body)
+GET  /api/control/{id}/preset?id=N # Select preset
+GET  /api/control/{id}/source?name=X # Select source
+```
+
+#### WebSocket Events
+- **Connection**: `ws://localhost:8080/ws`
+- **Device Updates**: Real-time device list changes
+- **Status Updates**: Live playback and volume changes
+- **Connection Monitoring**: Device availability status
+
+## Technical Implementation
+
+### Frontend Architecture
+- **Single HTML File**: Complete application in `static/index.html`
+- **Embedded CSS**: Bootstrap 5 with custom Bose-inspired styling
+- **Vanilla JavaScript**: No framework dependencies, fast performance
+- **Client-Side Routing**: JavaScript manages page state without reloads
+- **Dynamic Components**: HTML elements generated from JSON API responses
+
+### Error Handling & Validation
+- **Input Validation**: Proper bounds checking for volume (0-100) and bass (-9 to 9)
+- **HTTP Status Codes**: Appropriate response codes for different error conditions
+- **JSON Error Responses**: Structured error messages for API consumers
+- **Client-Side Error Display**: JavaScript toast notifications for user feedback
+
+### Code Quality
+- **golangci-lint Compliance**: Passes all configured lint checks
+- **Context Handling**: Proper context propagation and timeout management
+- **Error Checking**: All JSON encoding/decoding operations checked
+- **Type Safety**: Strong typing with dedicated type package
+- **Test Coverage**: Comprehensive unit tests for handlers and types
+
+### WebSocket Integration
+- **Gabbo Protocol**: Native SoundTouch WebSocket protocol implementation
+- **Event Processing**: Handles all documented SoundTouch WebSocket events
+- **Connection Management**: Automatic reconnection and health monitoring
+- **Bi-directional Communication**: Both status monitoring and device control
+
+## Dependencies
+
+### Core Libraries
+- **chi v5**: HTTP router (inherited from existing codebase)
+- **gorilla/websocket**: WebSocket implementation
+- **Go standard library**: html/template, net/http, encoding/json

+
+## API Endpoints
+
+The web UI exposes a REST API for programmatic control:
+
+### Device Management
+```
+GET  /api/devices           # List all discovered devices
+GET  /api/device/{id}       # Get specific device info
+POST /api/discover          # Trigger device discovery
+```
+
+### Device Control
+```
+GET  /api/control/{id}/play        # Start playback
+GET  /api/control/{id}/pause       # Pause playback
+GET  /api/control/{id}/stop        # Stop playback
+GET  /api/control/{id}/next        # Next track
+GET  /api/control/{id}/previous    # Previous track
+POST /api/control/{id}/volume      # Set volume (body: {"level": 50})
+GET  /api/control/{id}/mute        # Mute audio
+GET  /api/control/{id}/unmute      # Unmute audio
+POST /api/control/{id}/bass        # Set bass (body: {"level": 0})
+GET  /api/control/{id}/preset?id=1 # Select preset
+GET  /api/control/{id}/source?name=SPOTIFY # Select source
+```
+
+### WebSocket Events
+Connect to `/ws` for real-time updates:
+```javascript
+const ws = new WebSocket('ws://localhost:8080/ws');
+ws.onmessage = function(event) {
+    const data = JSON.parse(event.data);
+    // Handle device updates, status changes, etc.
+};
+```
+
+## Architecture
+
+### Single-Page Application Architecture
+- **JSON API Backend**: Go server providing RESTful endpoints
+- **Client-Side Rendering**: JavaScript handles all UI rendering
+- **WebSocket Real-time**: Bi-directional real-time communication
+- **No Template Dependencies**: Eliminates server-side template issues
+
+### Backend Components
+- **Discovery Service**: Finds and manages SoundTouch devices
+- **WebSocket Manager**: Maintains real-time connections to devices
+- **JSON API Server**: RESTful interface returning only JSON
+- **Device Manager**: Tracks device state and health
+
+### Frontend Components
+- **Bootstrap 5**: Modern responsive UI framework
+- **Vanilla JavaScript**: No framework dependencies, fast loading
+- **WebSocket Client**: Real-time bidirectional communication
+- **Dynamic Rendering**: Client-side HTML generation from JSON
+
+### Communication Flow
+1. **SPA Loading**: Single HTML file with embedded CSS and JavaScript
+2. **JSON API**: Device discovery and control via REST endpoints
+3. **WebSocket (Device)**: Real-time status updates from SoundTouch devices
+4. **WebSocket (Browser)**: Real-time UI updates to web clients
+5. **Client Rendering**: JavaScript dynamically creates all UI elements
+

+```
+
+## WebSocket Protocol Analysis
+
+This UI is based on extensive analysis of captured SoundTouch WebSocket interactions, including:
+
+### Message Types Implemented
+- **SoundTouchSdkInfo**: Initial handshake and version info
+- **nowPlayingUpdated**: Real-time track information
+- **volumeUpdated**: Audio level changes
+- **recentsUpdated**: Recently played items
+- **userActivityUpdate**: User interaction notifications
+
+### Request/Response Patterns
+- **Device Information**: System details and capabilities
+- **Audio Controls**: Volume, bass, mute controls
+- **Playback Control**: Play/pause/stop/skip commands
+- **Source Selection**: Input switching (Spotify, TuneIn, etc.)
+- **Preset Management**: Saved station/playlist access
+
+### Gabbo Protocol Features
+- **Persistent Connections**: Maintains long-lived WebSocket connections
+- **Request Correlation**: Uses request IDs for response matching
+- **Real-time Events**: Instant updates for all device state changes
+- **Bi-directional Control**: Both status monitoring and device control
+
+## Browser Compatibility
+
+### Supported Browsers
+- **Chrome 80+** (recommended)
+- **Firefox 75+**
+- **Safari 13+**
+- **Edge 80+**
+
+### Required Features
+- WebSocket support
+- CSS Grid and Flexbox
+- ES6 JavaScript features
+- Responsive CSS media queries
+
+## Security Considerations
+
+- **Local Network Only**: Designed for local network device control
+- **No Authentication**: Assumes trusted local network environment
+- **CORS Policy**: Restricted to same-origin requests
+- **WebSocket Security**: Uses same-origin WebSocket connections
+
+## Troubleshooting
+
+### Common Issues
+
+**Devices Not Found**
+- Ensure devices are on the same network
+- Check firewall settings (ports 8090, 8080)
+- Click "Discover Devices" button to trigger discovery
+
+**WebSocket Connection Failed**
+- Verify device supports WebSocket connections
+- Check browser console for connection errors
+- Refresh the page to reconnect WebSocket
+
+**Control Commands Not Working**
+- Check device is powered on and connected
+- Verify device is not in exclusive mode (e.g., Spotify Connect active)
+- Look for error notifications in the UI
+
+**Page Shows Template Errors**
+- This has been fixed in the SPA implementation
+- Ensure you're accessing the correct URL (localhost:8080)
+- Clear browser cache if you see old template-based content
+
+### Debug Mode
+Add verbose logging by setting environment variable:
+```bash
+export DEBUG=true
+./soundtouch-web
+```

+# 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.

+# 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.

+# note your device ID, e.g. "ABC123"
+
+adb -s ABC123 shell pm path com.bose.soundtouch
+# output e.g.: package:/data/app/~~xyz/com.bose.soundtouch-abc/base.apk
+
+adb -s ABC123 pull /data/app/~~xyz/com.bose.soundtouch-abc/base.apk bose.apk
+```
+
+---
+
+## 2. Create Android Emulator (ARM64, API 33)
+
+On Apple Silicon you need an ARM64 image. Use the `avdmanager` and `sdkmanager` CLI tools.
+
+```bash
+# Install the system image
+~/Library/Android/sdk/cmdline-tools/latest/bin/sdkmanager \
+  "system-images;android-33;google_apis;arm64-v8a"
+
+# Create the AVD
+~/Library/Android/sdk/cmdline-tools/latest/bin/avdmanager create avd \
+  -n Pixel_6_API33 \
+  -k "system-images;android-33;google_apis;arm64-v8a" \
+  -d "pixel_6"
+```
+
+Alternatively create the AVD via Android Studio Device Manager (choose "Google APIs", arm64-v8a, API 33).
+
+---
+
+## 3. Start Emulator with Writable System
+
+```bash
+# List available AVDs
+~/Library/Android/sdk/emulator/emulator -list-avds
+
+# Start with writable system partition
+~/Library/Android/sdk/emulator/emulator -avd Pixel_6_API33 -writable-system
+```
+
+Wait until the emulator has fully booted, then:
+
+```bash
+adb -s emulator-5554 root
+adb -s emulator-5554 shell avbctl disable-verification
+adb -s emulator-5554 reboot
+
+# After reboot:
+adb -s emulator-5554 root
+```
+
+---
+
+## 4. Install Bose APK
+
+```bash
+adb -s emulator-5554 install bose.apk
+```
+
+---
+
+## 5. Set Up mitmproxy
+
+```bash
+# Start mitmproxy (generates CA cert on first run)
+mitmweb --port 8080 --mode regular -w bose_traffic.mitm
+```
+
+Extract the CA certificate (without private key):
+
+```bash
+openssl x509 -in ~/.mitmproxy/mitmproxy-ca.pem -out ~/.mitmproxy/mitmproxy-ca-cert.pem
+
+# Verify it's the mitmproxy cert, not another cert:
+openssl x509 -in ~/.mitmproxy/mitmproxy-ca-cert.pem -noout -issuer
+# should show: issuer= /CN=mitmproxy/O=mitmproxy
+```
+
+---
+
+## 6. Install mitmproxy CA Certificate in Emulator
+
+```bash
+HASH=$(openssl x509 -inform PEM -subject_hash_old \
+  -in ~/.mitmproxy/mitmproxy-ca-cert.pem | head -1)
+
+adb -s emulator-5554 push ~/.mitmproxy/mitmproxy-ca-cert.pem /data/local/tmp/mitmproxy.pem
+
+adb -s emulator-5554 shell su 0 mkdir -p /data/misc/user/0/cacerts-added
+
+adb -s emulator-5554 shell su 0 \
+  cp /data/local/tmp/mitmproxy.pem /data/misc/user/0/cacerts-added/${HASH}.0
+
+adb -s emulator-5554 shell su 0 \
+  chmod 644 /data/misc/user/0/cacerts-added/${HASH}.0
+```
+
+---
+
+## 7. Set System Proxy in Emulator
+
+Find your Mac's local IP:
+
+```bash
+ipconfig getifaddr en0
+# e.g. 192.168.1.123
+```
+
+Set the proxy:
+
+```bash
+adb -s emulator-5554 shell settings put global http_proxy 192.168.1.123:8080
+```
+
+---
+
+## 8. Set Up Frida (via Python venv)
+
+```bash
+python3 -m venv /tmp/frida-venv
+/tmp/frida-venv/bin/pip install frida==17.9.1 frida-tools==14.8.1
+```
+
+Download the frida-server binary for ARM64 Android:
+
+```bash
+FRIDA_VERSION=17.9.1
+
+curl -L "https://github.com/frida/frida/releases/download/${FRIDA_VERSION}/frida-server-${FRIDA_VERSION}-android-arm64.xz" \
+  -o /tmp/frida-server.xz
+
+unxz /tmp/frida-server.xz
+mv /tmp/frida-server-${FRIDA_VERSION}-android-arm64 /tmp/frida-server
+```
+
+Push to emulator and start:
+
+```bash
+adb -s emulator-5554 push /tmp/frida-server /data/local/tmp/frida-server
+adb -s emulator-5554 shell su 0 chmod 755 /data/local/tmp/frida-server
+adb -s emulator-5554 shell su 0 /data/local/tmp/frida-server &
+```
+
+---
+
+## 9. Download SSL Bypass Scripts
+
+```bash
+BASE=https://raw.githubusercontent.com/httptoolkit/frida-interception-and-unpinning/main
+
+curl -L "${BASE}/config.js" -o /tmp/config.js
+curl -L "${BASE}/android/android-system-certificate-injection.js" \
+  -o /tmp/android-system-certificate-injection.js
+curl -L "${BASE}/android/android-proxy-override.js" \
+  -o /tmp/android-proxy-override.js
+curl -L "${BASE}/android/android-certificate-unpinning.js" \
+  -o /tmp/android-certificate-unpinning.js
+curl -L "${BASE}/android/android-certificate-unpinning-fallback.js" \
+  -o /tmp/android-certificate-unpinning-fallback.js
+```
+
+---
+
+## 10. Configure config.js
+
+Edit `/tmp/config.js` and set:
+
+```javascript
+const CERT_PEM = `<contents of ~/.mitmproxy/mitmproxy-ca-cert.pem>`;
+
+const PROXY_HOST = '192.168.1.123';  // your Mac IP
+const PROXY_PORT = 8080;
+```
+
+Insert the full PEM content (from `-----BEGIN CERTIFICATE-----` to `-----END CERTIFICATE-----`) between the backticks.
+
+Quick check that the right cert is in place:
+
+```bash
+# The issuer inside config.js should be mitmproxy, not SoundTouch
+grep -A3 "CERT_PEM" /tmp/config.js | head -5
+```
+
+---
+
+## 11. Start Interception
+
+Make sure mitmweb is running, then:
+
+```bash
+/tmp/frida-venv/bin/frida \
+  -U \
+  -f com.bose.soundtouch \
+  -l /tmp/config.js \
+  -l /tmp/android-system-certificate-injection.js \
+  -l /tmp/android-proxy-override.js \
+  -l /tmp/android-certificate-unpinning.js \
+  -l /tmp/android-certificate-unpinning-fallback.js
+```
+
+Expected output in the Frida REPL:
+
+```
+== System certificate trust injected ==
+== Proxy system configuration overridden to 192.168.1.123:8080 ==
+== Proxy configuration overridden to 192.168.1.123:8080 ==
+== Certificate unpinning completed ==
+== Unpinning fallback auto-patcher installed ==
+```
+
+Open mitmweb at `http://127.0.0.1:8081` to observe traffic live.
+
+---
+
+## 12. Save & Replay Recordings
+
+Traffic is saved to `bose_traffic.mitm` (set via `-w` flag in step 5).
+
+```bash
+# Replay/analyse a saved recording:
+mitmweb -r bose_traffic.mitm
+```
+
+---
+
+## Cleanup
+
+```bash
+# Remove proxy setting from emulator
+adb -s emulator-5554 shell settings delete global http_proxy
+
+# Remove venv
+rm -rf /tmp/frida-venv /tmp/frida-server /tmp/frida-server.xz
+rm /tmp/config.js /tmp/android-*.js
+
+# Stop emulator
+adb -s emulator-5554 emu kill
+```
+
+---
+

+
+## App Automation Options
+
+For most traffic-recording purposes, manually operating the app while mitmproxy captures is sufficient. If you need to automate specific interactions (e.g. to repeatably capture the requests triggered by startup or a particular action), the following tools are available.
+
+### Starting the App
+
+```bash
+# Via app drawer: swipe up on the home screen and tap "Bose SoundTouch"
+
+# Via adb monkey (simplest)
+adb -s emulator-5554 shell monkey -p com.bose.soundtouch 1
+
+# Via explicit intent (if the activity name is known)
+adb -s emulator-5554 shell am start -n com.bose.soundtouch/.MainActivity
+
+# Look up all activities if the name is unknown
+adb -s emulator-5554 shell dumpsys package com.bose.soundtouch | grep Activity
+```
+
+### adb — sufficient for simple cases
+
+```bash
+# Tap at screen coordinates
+adb shell input tap 540 960
+
+# Swipe
+adb shell input swipe 540 1500 540 500
+
+# Type text
+adb shell input text "mytext"
+
+# Take a screenshot
+adb shell screencap /sdcard/screen.png && adb pull /sdcard/screen.png
+```
+
+### UIAutomator2 — inspect UI elements
+
+```bash
+# Dump the current UI hierarchy to find element IDs
+adb shell uiautomator dump /sdcard/ui.xml
+adb pull /sdcard/ui.xml
+```
+
+Open `ui.xml` to find element resource IDs, then target them precisely in scripts.
+
+### Appium — full scripted automation
+
+```python
+from appium import webdriver
+
+driver = webdriver.Remote('http://localhost:4723/wd/hub', {
+    'platformName': 'Android',
+    'appPackage': 'com.bose.soundtouch',
+    'appActivity': '.MainActivity',
+})
+
+# Find an element by resource ID and tap it
+driver.find_element('id', 'com.bose.soundtouch:id/play_button').click()
+```
+
+> **Note:** `monkey` is a stress-test tool that sends random events — use it only to launch the app, not to drive specific interactions.

+# Bose SoundTouch – Traffic Analysis Runbook
+
+> **Goal:** Set up a Raspberry Pi as a transparent access point to fully observe the traffic of the Bose SoundTouch app – specifically the pairing flow with the Bose Cloud. This serves as a basis for later reverse engineering / simulation of the cloud endpoints.
+
+---
+
+## Prerequisites
+
+| Component          | Details                                                          |
+|--------------------|------------------------------------------------------------------|
+| Raspberry Pi       | Pi 3 or newer, Raspberry Pi OS (Bullseye, Bookworm, Trixie)      |
+| Network interfaces | `eth0` → LAN cable to FritzBox, `wlan0` → own Access Point       |
+| FritzBox           | Unchanged, assigns an IP to the Pi via DHCP on eth0              |
+| Custom DNS Server  | Already present (or see Appendix A), incl. custom CA certificate |
+| Phone              | Android, connects to the Pi's Wi-Fi                              |
+
+### Network Architecture
+
+```
+Internet
+    ↓
+FritzBox  (existing, unchanged)
+    ↓  LAN cable (eth0)
+Raspberry Pi
+  ├── DNS Server       → selective logging / redirection
+  ├── hostapd          → custom Wi-Fi Access Point ("Bose-Lab")
+  ├── dnsmasq          → DHCP for clients, DNS to custom server
+  ├── iptables         → NAT, Forwarding eth0 ↔ wlan0
+  ├── tcpdump          → full traffic capture
+  └── (optional) mitmproxy → HTTPS decryption
+    ↓  Wi-Fi ("Bose-Lab")
+Android Phone
+  └── Bose SoundTouch App
+```
+
+---
+
+## Step 1 – Install Packages
+
+```bash
+sudo apt update && sudo apt install -y \
+  hostapd \          # Wi-Fi Access Point daemon
+  dnsmasq \          # DHCP + DNS forwarding
+  nftables \         # Modern NAT / firewall / forwarding
+  tcpdump \          # Packet capture at all levels
+  wireshark-common   # tshark CLI (optional, for live analysis)
+```
+
+---
+
+## Step 2 – Enable IP Forwarding
+
+The Pi must forward packets between `wlan0` (phone) and `eth0` (FritzBox).
+
+```bash
+# Active immediately (no reboot required)
+sudo sysctl -w net.ipv4.ip_forward=1
+
+# Permanent (survives reboots)
+# On modern Debian, using a dedicated file in sysctl.d/ is more reliable:
+echo "net.ipv4.ip_forward=1" | sudo tee /etc/sysctl.d/99-ip-forward.conf
+
+# Apply changes immediately
+sudo sysctl --system
+```
+
+**Verify:**
+```bash
+# After a reboot, ensure it is still '1'
+cat /proc/sys/net/ipv4/ip_forward
+```
+
+---
+
+## Step 3 – Static IP on wlan0 (systemd-networkd)
+
+On modern Debian (Bookworm/Trixie), `dhcpcd` is replaced by `systemd-networkd`.
+
+```bash
+# Create network configuration
+sudo tee /etc/systemd/network/08-wlan0.network << 'EOF'
+[Match]
+Name=wlan0
+
+[Network]
+Address=192.168.10.1/24
+IPForward=yes
+ConfigureWithoutCarrier=yes
+DHCP=no
+IPv6AcceptRA=no
+EOF
+
+# Restart service
+sudo systemctl enable systemd-networkd
+sudo systemctl restart systemd-networkd
+
+# Ensure wpa_supplicant and NetworkManager don't interfere
+sudo nmcli device set wlan0 managed no
+sudo systemctl stop wpa_supplicant@wlan0
+sudo systemctl mask wpa_supplicant@wlan0
+```
+
+**Verify:**
+```bash
+ip addr show wlan0
+# Expected: ONLY inet 192.168.10.1/24 (NO second DHCP IP)
+```
+
+---
+
+## Step 4 – hostapd (Access Point)
+
+```bash
+sudo tee /etc/hostapd/hostapd.conf << 'EOF'
+interface=wlan0
+driver=nl80211
+ssid=Bose-Lab
+hw_mode=b
+#hw_mode=g
+channel=1
+#channel=6
+wmm_enabled=0
+auth_algs=1
+wpa=2
+wpa_passphrase=secret123
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=CCMP
+EOF
+
+# The modern way is to just use hostapd.service which defaults to /etc/hostapd/hostapd.conf
+sudo systemctl unmask hostapd
+sudo systemctl enable --now hostapd
+```
+
+**Verify:**
+```bash
+sudo systemctl status hostapd
+# Expected: active (running)
+```
+
+---
+
+## Step 5 – dnsmasq (DHCP + DNS)
+
+dnsmasq gives the phone an IP and forwards DNS queries to the custom DNS server.
+
+```bash
+# Back up original config
+sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.bak
+
+sudo tee /etc/dnsmasq.conf << 'EOF'
+interface=wlan0
+dhcp-range=192.168.10.100,192.168.10.200,24h
+dhcp-option=3,192.168.10.1
+dhcp-option=6,192.168.10.1
+
+# DNS Upstream: custom server on localhost (adjust port if necessary)
+server=127.0.0.1#5353    # Example: custom server on port 5353
+# Alternatively: server=1.1.1.1 if DNS server runs directly on port 53
+
+# Log all DNS queries (for initial analysis)
+log-queries
+log-facility=/var/log/dnsmasq.log
+EOF
+
+sudo systemctl restart dnsmasq
+```
+
+**Observe DNS log live:**
+```bash
+sudo tail -f /var/log/dnsmasq.log
+```
+
+---
+
+## Step 6 – NAT and Forwarding (nftables)
+
+On modern Debian (Bookworm/Trixie), `nftables` is the default and recommended way to manage NAT and traffic forwarding.
+
+```bash
+# Define the NAT and Forwarding rules
+sudo tee /etc/nftables.conf << 'EOF'
+#!/usr/sbin/nft -f
+
+flush ruleset
+
+table inet filter {
+    chain forward {
+        type filter hook forward priority 0; policy drop;
+
+        # Allow traffic from phone (wlan0) to internet (eth0)
+        iifname "wlan0" oifname "eth0" accept
+
+        # Allow established/related traffic back to the phone
+        iifname "eth0" oifname "wlan0" ct state established,related accept
+    }
+}
+
+table ip nat {
+    chain posterouting {
+        type nat hook postrouting priority 100; policy accept;
+
+        # MASQUERADE outgoing packets on eth0
+        oifname "eth0" masquerade
+    }
+}
+EOF
+
+# Enable and start nftables
+sudo systemctl enable nftables
+sudo systemctl restart nftables
+```
+
+**Verify:**
+```bash
+sudo nft list ruleset
+# Expected: ruleset showing the forward and nat chains
+```
+
+### WiFi "Bose-Lab" not visible?
+
+If you cannot see the `Bose-Lab` SSID on your phone:
+
+1.  **Check hostapd status:** `sudo systemctl status hostapd`. If it failed with "nl80211: Driver does not support configured mode", try changing `hw_mode=g` to `hw_mode=b`.
+2.  **Interface blocking:** Ensure `rfkill` hasn't blocked WiFi: `sudo rfkill unblock wlan`.
+3.  **Country Code:** Some systems require a country code in `hostapd.conf` to enable the radio. Add `country_code=DE` (or your country) to the top of `/etc/hostapd/hostapd.conf` and restart hostapd: `sudo systemctl restart hostapd`.
+4.  **Local Radio Check:** You can verify that the radio is actually configured as an AP: `iw dev wlan0 info`. Look for `type AP` and your SSID.
+    > **Note:** Do NOT rely on `iw dev wlan0 scan` for your own SSID; many WiFi drivers cannot "scan" and "broadcast" simultaneously.
+5.  **Debug Mode:** If the scan still returns nothing, stop the service and run hostapd in the foreground to see real-time errors:
+    ```bash
+    sudo systemctl stop hostapd
+    sudo hostapd -dd /etc/hostapd/hostapd.conf
+    ```
+    Look for messages like `nl80211: Failed to set interface wlan0 into AP mode`. This usually means the hardware is busy or doesn't support the current `hw_mode` / `channel` combination.
+6.  **Conflicting Services:** Ensure nothing else is managing `wlan0`. NetworkManager is common on modern Debian:
+    ```bash
+    sudo nmcli device set wlan0 managed no
+    ```
+7.  **Ghost IP Conflict:** If `ip addr show wlan0` shows both `192.168.10.1` and another IP (like `192.168.178.x`), `hostapd` will fail. This is usually caused by NetworkManager managing the interface. Ensure you've run:
+    ```bash
+    sudo nmcli device set wlan0 managed no
+    # If the ghost IP is still there, remove it manually:
+    sudo ip addr del 192.168.178.X/24 dev wlan0
+    ```
+
+---
+
+## Step 7 – Install Custom CA Certificate on the Phone
+
+Since a custom DNS server with a custom CA certificate is used, it must be trusted on the phone – otherwise, the app will block HTTPS connections to redirected domains.
+
+### Copy CA Certificate to the Pi (if not already there)
+
+If you haven't created a CA yet, follow **Appendix A** first.
+
+```bash
+# Certificate is located e.g. at /etc/my-dns-ca/ca.crt
+# Temporarily make reachable via HTTP for easy download:
+cd /etc/my-dns-ca/
+python3 -m http.server 8080
+# → Reachable at http://192.168.10.1:8080/ca.crt
+```
+
+### Install on Android
+
+1. Connect phone to `Bose-Lab`
+2. Open browser → `http://192.168.10.1:8080/ca.crt`
+3. Download certificate
+4. **Settings → Security → Credentials → Install CA Certificate**
+5. Select certificate and confirm
+
+> **Note:** Android distinguishes between system CAs and user CAs. User-installed CAs are accepted by many apps, but apps with certificate pinning (hardcoded certificate hashes) ignore them. Whether Bose uses pinning will be visible in the capture (Connection Reset after TLS ClientHello).
+
+### Android 14+ Special Case
+
+From Android 14 onwards, apps do not trust user CAs by default unless explicitly declared in the manifest. If the Bose app rejects the CA certificate:
+
+```bash
+# Option A: Root + Magisk module "MagiskTrustUserCerts"
+#   → moves user CAs to the system store
+
+# Option B: Root + manually copy to system CA directory
+adb push ca.crt /system/etc/security/cacerts/
+adb shell chmod 644 /system/etc/security/cacerts/ca.crt
+```
+
+---
+
+## Step 8 – Capture Traffic
+
+### All at once (recommended)
+
+```bash
+# Full capture of all protocols on wlan0
+# Filename with timestamp for multiple sessions
+sudo tcpdump -i wlan0 \
+  -w /tmp/bose-$(date +%Y%m%d-%H%M%S).pcap \
+  -s 0        # full packet length (no truncation)
+
+# End session: Ctrl+C
+```
+
+### Targeted by protocol
+
+```bash
+# DNS only (Port 53) – shows if app uses standard DNS
+sudo tcpdump -i wlan0 -n port 53
+
+# HTTPS only – TLS connections to Bose Cloud
+sudo tcpdump -i wlan0 -n 'tcp port 443'
+
+# mDNS (ZeroConf) – device discovery in LAN
+# Multicast group 224.0.0.1, Port 5353
+sudo tcpdump -i wlan0 -n 'udp port 5353'
+
+# SSDP/UPnP – alternative device discovery
+sudo tcpdump -i wlan0 -n 'udp port 1900'
+
+# Everything except DNS (reduces noise)
+sudo tcpdump -i wlan0 -n 'not port 53' -w /tmp/bose-nodns.pcap
+
+# Traffic of a specific host only (filter by phone IP)
+# Read phone IP from dnsmasq.leases beforehand (see below)
+sudo tcpdump -i wlan0 -n host 192.168.10.101
+```
+
+### Read SNI from TLS Traffic (without decryption)
+
+```bash
+# Extract domains from TLS ClientHello (SNI is unencrypted)
+sudo tcpdump -i wlan0 -n 'tcp port 443' -A 2>/dev/null \
+  | grep -oP '(?<=\x00)([a-zA-Z0-9.-]+\.(?:com|net|io|cloud|bose\.com))'
+```
+
+### Readable mDNS Announcements output
+
+```bash
+# tshark decodes mDNS directly
+sudo tshark -i wlan0 -f 'udp port 5353' -T fields \
+  -e dns.qry.name \
+  -e dns.resp.name \
+  -e dns.a
+```
+
+---
+
+## Step 9 – Analysis with Wireshark (on PC)
+
+Transfer `.pcap` files from the Pi to the PC:
+
+```bash
+# From the PC (scp)
+scp pi@192.168.10.1:/tmp/bose-*.pcap ~/Desktop/
+```
+
+**Important Wireshark Filters:**
+
+```
+# DNS only
+dns
+
+# HTTPS only
+tcp.port == 443
+
+# WebSocket connections (HTTP Upgrade)
+websocket
+
+# mDNS
+mdns
+
+# TLS Handshakes (SNI visible)
+tls.handshake.extensions_server_name
+
+# Traffic of a specific domain (resolve by IP)
+http.host contains "bose"
+
+# WebSocket frames
+websocket.payload
+```
+
+> **Tip:** Wireshark decodes WebSocket frames automatically if it sees the HTTP Upgrade handshake in the same capture. For the pairing flow: filtering for `tls.handshake.extensions_server_name` shows all domains the app contacts, even without decryption.
+
+---
+
+## Step 10 – mitmproxy (optional, for HTTPS content)
+
+Only useful if the CA certificate on the phone is trusted and no certificate pinning is active. `mitmproxy` acts as a Man-in-the-Middle by generating fake, on-the-fly certificates for any domain (e.g., `global.api.bose.io`) using your custom CA.
+
+### 1. Configure mitmproxy to use your Custom CA
+
+By default, `mitmproxy` creates its own CA in `~/.mitmproxy/`. To ensure the phone (which already trusts your `ca.crt`) accepts the traffic, you must tell `mitmproxy` to use your existing CA:
+
+```bash
+# mitmproxy expects the CA in a specific PEM format (cert + key in one file)
+sudo mkdir -p ~/.mitmproxy
+sudo cat /etc/my-dns-ca/ca.crt /etc/my-dns-ca/ca.key | sudo tee ~/.mitmproxy/mitmproxy-ca.pem > /dev/null
+```
+
+### 2. Install and Start mitmproxy
+
+```bash
+# Install mitmproxy binary (stable version for aarch64)
+cd /tmp
+wget https://downloads.mitmproxy.org/12.2.1/mitmproxy-12.2.1-linux-aarch64.tar.gz
+tar -xzf mitmproxy-12.2.1-linux-aarch64.tar.gz
+sudo mv mitmproxy mitmdump mitmweb /usr/local/bin/
+rm mitmproxy-12.2.1-linux-aarch64.tar.gz
+
+mitmproxy --version
+
+# Transparent proxy on port 8080
+# It will now use the CA from ~/.mitmproxy/mitmproxy-ca.pem
+mitmproxy --mode transparent --listen-port 8080
+
+# Alternatively: mitmdump for automatic logging to file
+# mitmdump --mode transparent --listen-port 8080 -w /tmp/bose-https.mitm
+```
+
+### 3. Troubleshooting: TLS Handshake Failures
+
+If you see `Client TLS handshake failed. The client does not trust the proxy's certificate for www.google.com` (or other domains) in the `mitmproxy` logs:
+
+1.  **HSTS and Pre-installed Pinning:** High-security sites like `www.google.com` use **HSTS (HTTP Strict Transport Security)** and have their certificates hardcoded (pinned) into browsers like Chrome and the Android system. **These will always fail with a User-installed CA.**
+2.  **User vs. System CA Store:** On Android 7.0+, apps **do not trust User-installed CAs by default**. They only trust the "System" store.
+    *   **The Bose app:** If it fails, it's because it only trusts the System store or uses its own certificate pinning.
+    *   **The Fix (Rooted Phone):** Use a Magisk module like `AlwaysTrustUserCerts` or manually move your `ca.crt` to `/system/etc/security/cacerts/` (see Step 7).
+3.  **The "Golden Rule" - Verify the Proxy is Working:**
+    To confirm your CA and `mitmproxy` are correctly configured, test with a non-HSTS site on the phone's browser (e.g., `http://neverssl.com`). Once redirected to HTTPS, **inspect the certificate**. It should say it was issued by your "Bose-Lab Root CA" (or "SoundTouch Root CA").
+
+    *   **If this works:** Your "factory" (mitmproxy + CA) is 100% correct. Any failure in the Bose app is due to its own security policy (ignore User Store or Pinning).
+    *   **If this fails:** Your CA is not trusted by the browser or `mitmproxy` is not using your PEM file.
+
+    Alternatively, use `curl` from a terminal emulator on the phone:
+    ```bash
+    # This should work if the CA is in the user store and curl is told to use it
+    curl -v --cacert /path/to/ca.crt https://example.com
+    ```
+4.  **Check mitmproxy CA:** Ensure `mitmproxy` is actually using your CA. When it starts, it should NOT generate a new CA in `~/.mitmproxy/mitmproxy-ca.pem` if you've already placed yours there.
+
+---
+
+**nftables rule: redirect HTTPS traffic to mitmproxy**
+
+```bash
+# Create a temporary file for the redirection rule
+sudo nft add table ip mitm
+sudo nft add chain ip mitm prerouting { type nat hook prerouting priority -100 \; }
+sudo nft add rule ip mitm prerouting iifname "wlan0" tcp dport 443 redirect to :8080
+```
+
+**Remove rule when no longer needed:**
+
+```bash
+sudo nft delete table ip mitm
+```
+
+> **Detecting Certificate Pinning:** If the app immediately disconnects after mitmproxy redirection (connection reset directly after TLS ClientHello), pinning is active. In this case, Frida + root is needed to patch the pinning.
+
+---
+
+## Step 11 – Bypassing Android Trust Restrictions
+
+If `neverssl.com` works in the browser but the Bose app shows `TLS handshake failed` in `mitmproxy`, the app is either ignoring the **User CA store** (common on Android 7+) or using **Certificate Pinning**.
+
+### Option A: Move CA to System Store (Requires Root/Magisk)
+
+This is the most reliable way to make apps trust your CA without modifying the app itself.
+
+1.  **Using Magisk (Recommended):**
+    Install the **"AlwaysTrustUserCerts"** or **"Move Certificates"** module in Magisk. It automatically mirrors all certificates from the User store to the System store on every boot.
+
+2.  **Manual Move (via ADB):**
+    Android system certificates are stored in `/system/etc/security/cacerts/` and must be named using the hash of the certificate.
+
+    ```bash
+    # 1. Get the hash of your certificate
+    hash=$(openssl x509 -inform PEM -subject_hash_old -in ca.crt | head -1)
+
+    # 2. Rename the certificate locally
+    cp ca.crt ${hash}.0
+
+    # 3. Push to the phone (requires remounting /system as read-write)
+    adb push ${hash}.0 /sdcard/
+    adb shell
+    su
+    mount -o rw,remount /
+    cp /sdcard/${hash}.0 /system/etc/security/cacerts/
+    chmod 644 /system/etc/security/cacerts/${hash}.0
+    chown root:root /system/etc/security/cacerts/${hash}.0
+    reboot
+    ```
+
+### Option B: Patching the App (No Root Required)
+
+If you cannot root your phone, you can modify the app's APK to trust user-installed certificates. This involves obtaining the APK, decompiling it, adding a network security configuration, and then repackaging and signing it.
+
+#### 0. How to get the .apk file?
+
+You have two main ways to get the official Bose SoundTouch APK:
+
+**Method 1: Extract from your phone (Safest)**
+If the app is already installed on your phone, you can pull it using `adb`:
+```bash
+# 1. Find the package name (usually com.bose.soundtouch)
+adb shell pm list packages | grep bose
+
+# 2. Get the full path to the APK on the phone
+adb shell pm path com.bose.soundtouch
+# Output: package:/data/app/~~...==/com.bose.soundtouch-.../base.apk
+
+# 3. Pull the file to your computer
+adb pull /data/app/~~...==/com.bose.soundtouch-.../base.apk Bose-SoundTouch.apk
+```
+
+**Method 2: Download from a Mirror (Easiest)**
+You can download the APK from reputable third-party sites.
+> **Warning:** Always verify the site's reputation.
+*   [APKMirror](https://www.apkmirror.com/apk/bose-corporation/bose-soundtouch/)
+*   [APKPure](https://apkpure.com/bose-soundtouch/com.bose.soundtouch)
+
+#### 1. Automated Method: apk-mitm (Recommended)
+The easiest way is to use `apk-mitm`, which automates the entire process including fixing common certificate pinning libraries.
+
+```bash
+# Requires Node.js installed on your PC
+npx apk-mitm Bose-SoundTouch.apk
+```
+This will produce a `Bose-SoundTouch-patched.apk` which you can install on your phone.
+
+#### 2. Manual Method: Network Security Config
+If you prefer to do it manually:
+
+1.  **Decompile the APK:**
+    ```bash
+    apktool d Bose-SoundTouch.apk
+    ```
+2.  **Create/Modify `res/xml/network_security_config.xml`:**
+    ```xml
+    <?xml version="1.0" encoding="utf-8"?>
+    <network-security-config>
+        <base-config>
+            <trust-anchors>
+                <certificates src="system" />
+                <certificates src="user" />
+            </trust-anchors>
+        </base-config>
+    </network-security-config>
+    ```
+3.  **Update `AndroidManifest.xml`:**
+    Ensure the `<application>` tag includes: `android:networkSecurityConfig="@xml/network_security_config"`.
+4.  **Repackage and Sign:**
+    ```bash
+    apktool b Bose-SoundTouch -o Bose-SoundTouch-patched.apk
+    # Sign with your own key
+    # 1. Generate a keystore (if you don't have one)
+    # Note: You can use ANY name/values here. The phone does not need to "know" or "trust" this key beforehand.
+    # It only needs the APK to be digitally signed so the Android installer accepts it.
+    keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
+
+    # 2. Sign the APK
+    apksigner sign --ks my-release-key.keystore --out Bose-SoundTouch-patched-signed.apk Bose-SoundTouch-patched.apk
+
+    # Alternatively, use uber-apk-signer (recommended for simplicity)
+    # It handles zipalign and signing automatically.
+    java -jar uber-apk-signer.jar --apk Bose-SoundTouch-patched.apk
+    ```
+
+#### 3. Install the Patched APK
+
+Once you have your `Bose-SoundTouch-patched.apk` (and it is signed), you need to install it on your phone.
+
+**Important:** You must **uninstall the original Bose app first**. Android will not allow you to "update" the official app with your patched version because the digital signatures won't match.
+
+**Method 1: via ADB (Recommended)**
+```bash
+# 1. Uninstall the original app
+adb uninstall com.bose.soundtouch
+
+# 2. Install your patched version
+adb install Bose-SoundTouch-patched.apk
+```
+
+**Method 2: Manual Transfer**
+1.  Copy the `Bose-SoundTouch-patched.apk` to your phone's storage (via USB, Google Drive, or the Pi's HTTP server).
+2.  On the phone, use a File Manager to open the APK.
+3.  If prompted, allow "Install from Unknown Sources" for your File Manager.
+
+### Option C: Using the macOS Bose SoundTouch App (No Root/Patching Required)
+
+If you have a Mac, using the macOS version of the Bose SoundTouch app is often a good alternative. However, because the app is built on an **older version of Qt (5.7.0)**, it has specific trust and TLS compatibility issues that require extra steps.
+
+#### 1. Install the Custom CA in macOS Keychain
+
+1.  Open **Keychain Access** on your Mac.
+2.  Select the **System** keychain (or **login** if System is locked).
+3.  Drag and drop your `ca.crt` file into the list.
+4.  Double-click the newly added certificate (e.g., "Bose-Lab Root CA").
+5.  Expand the **Trust** section.
+6.  Set "When using this certificate" to **Always Trust**.
+7.  Close the window and authenticate with your Mac password.
+
+#### 2. Configure the Proxy
+
+You can either configure the macOS system proxy manually or use `mitmproxy`'s automatic interception.
+
+**Method 1: System Proxy (Manual)**
+1.  Go to **System Settings → Network → Wi-Fi → Details... → Proxies**.
+2.  Enable **HTTP Proxy** and **HTTPS Proxy**.
+3.  Set Server to your Pi's IP (`192.168.10.1`) and Port to `8080`.
+4.  Click **OK** and **Apply**.
+
+**Method 2: mitmproxy Local Redirect (Automatic)**
+If you are running `mitmproxy` directly on your Mac (instead of the Pi), you can use the modern "Local Redirect" mode which doesn't require proxy settings:
+```bash
+# Install mitmproxy via Homebrew
+brew install mitmproxy
+
+# Start mitmproxy in local redirect mode
+# This uses a macOS Network Extension to intercept traffic from specific apps
+mitmproxy --mode local
+```
+
+#### 3. Special Troubleshooting: Legacy Qt 5.7.0 SSL Failures
+
+If you see `SSL handshake failed` in the `mitmproxy` logs or the app's internal log (`log.txt`), the app's older networking stack is rejecting the connection. This is common because Qt 5.7.0 (2016) lacks support for **TLS 1.3** and many modern root certificates (like Let's Encrypt's **ISRG Root X1**).
+
+**The Solution: Launch with SSL Bypass Flags**
+
+Since the Bose macOS app is a hybrid of **Qt/Chromium** and **Node.js**, you must bypass the trust checks for both engines by launching the app from the terminal:
+
+```bash
+# 1. Bypass QtWebEngine/Chromium (Qt 5.7) trust
+export QTWEBENGINE_CHROMIUM_FLAGS="--ignore-certificate-errors"
+
+# 2. Bypass Node.js (SoundTouch Music Server) trust
+export NODE_TLS_REJECT_UNAUTHORIZED=0
+
+# 3. (Optional) Provide your custom CA directly to Node.js
+export NODE_EXTRA_CA_CERTS="/path/to/your/ca.crt"
+
+# 4. Launch the application
+"/Applications/SoundTouch/SoundTouch.app/Contents/MacOS/SoundTouch"
+```
+
+#### 4. Verify and Capture
+
+1.  Open Safari and visit `https://neverssl.com`. Verify the certificate is issued by your custom CA.
+2.  Launch the Bose app using the terminal command above.
+3.  Watch the traffic flow in `mitmproxy`.
+
+> **Note:** Even on macOS, **Certificate Pinning** is still possible if Bose implemented it specifically in the desktop app code. However, it is much less common on desktop apps than on mobile apps. If it works, you've saved yourself hours of Android patching!
+
+### Option D: Patching the App with Frida (Requires Root)
+
+If the app uses **Certificate Pinning** (hardcoded hashes), even moving the CA to the System store won't work. You must disable the pinning check in the app's code.
+
+1.  **Install Frida** on your PC and `frida-server` on the rooted phone.
+2.  **Use a universal bypass script:**
+    ```bash
+    frida -U -f com.bose.soundtouch -l https://codeshare.frida.re/@pcipolloni/universal-android-ssl-pinning-bypass-with-frida/ --no-pause
+    ```
+    *(Replace `com.bose.soundtouch` with the actual package name if different).*
+
+## Step 12 – Alternative: Regular HTTP Proxy Mode
+
+If the **Transparent AP** setup (Steps 1–6) is too complex or you are experiencing routing issues, you can use `mitmproxy` as a **Regular HTTP Proxy**.
+
+### 1. How it works
+In this mode, the Pi acts as a simple server on port 8080. You tell your phone's Wi-Fi settings to send all traffic to `192.168.10.1:8080`.
+
+*   **Pros:** No complex `nftables` or NAT rules required.
+*   **Cons:** Many Android apps (and background processes) ignore system-wide proxy settings. **HTTPS still requires a trusted CA for decryption.**
+
+### 2. Start mitmproxy in Regular Mode
+```bash
+# Stop transparent mode first if it's running
+# No special flags needed for regular mode
+mitmproxy --listen-port 8080
+```
+
+### 3. Configure the Phone
+1.  Go to **Settings → Wi-Fi → Bose-Lab**.
+2.  Select **Modify Network** (or the "i" icon).
+3.  Set **Proxy** to **Manual**.
+4.  **Proxy hostname:** `192.168.10.1`
+5.  **Proxy port:** `8080`
+6.  Save and try to browse a site.
+
+---
+
+## Step 13 – Extracting for soundtouch-service
+
+You can extract interactions (especially unencrypted WebSockets on port 8090) from a `.pcap` and format them for use in `soundtouch-service`.
+
+### 1. Extract Traffic using Go
+
+A helper script is provided in `scripts/extract-ws.go`. It automatically detects, unmasks, and decompresses (GZIP) WebSocket frames, and also extracts DNS, MDNS, and SSDP traffic.
+
+```bash
+# Install dependencies
+go get github.com/google/gopacket
+
+# Run extraction (outputs multiple files: .ws.http, .dns.txt, .mdns.txt, .ssdp.txt)
+# The results will be saved beside your .pcap file
+go run scripts/extract-ws.go your_capture.pcap [filter_ip]
+
+# Example: Filter for a specific speaker's IP in WebSocket messages
+go run scripts/extract-ws.go capture.pcap 192.168.100.1
+```
+
+### 2. Manual Extraction with tshark
+
+If you only need a quick look at the payloads:
+
+```bash
+# Extract all WebSocket text payloads
+tshark -r your_capture.pcap -Y "websocket.payload.text" -T fields -e websocket.payload.text
+```
+
+---
+
+## Step 14 – Extracting from Internal App Logs (macOS)
+
+If you are using the macOS app and cannot decrypt the cloud traffic due to pinning, you can still extract the JSON/XML messages from the app's internal communication log.
+
+A helper script is provided in `scripts/extract-log-interactions.go`. It parses the interleaved "Native" and "Network" calls to reconstruct the application's internal state and cloud requests.
+
+```bash
+# Run extraction from the log file
+# Outputs a chronological record of internal events and network URLs
+go run scripts/extract-log-interactions.go path/to/log.txt > extracted-interactions.http
+```
+
+**What this shows:**
+- **TO NETWORK:** The URLs the app is about to call (intercepted before encryption).
+- **FROM NATIVE:** Data being returned from the OS or Cloud to the UI.
+- **TO NATIVE:** Commands being sent from the UI to the underlying engines.
+
+This is a powerful "Plan B" when HTTPS decryption is blocked, as the app essentially logs its own decrypted data for you.
+
+---
+
+## Helper Commands / Troubleshooting
+
+After a Pi reboot, everything should come up automatically. If not:
+
+```bash
+# Restart and enable all core services
+sudo systemctl restart systemd-networkd
+sudo systemctl enable --now hostapd
+sudo systemctl enable --now dnsmasq
+sudo systemctl restart nftables
+
+# Verify the unmanaged state of wlan0 (nmcli)
+sudo nmcli device set wlan0 managed no
+```
+
+---
+
+## What to Expect
+
+| Protocol             | Port       | Tool                     | Visibility                                     |
+|----------------------|------------|--------------------------|------------------------------------------------|
+| DNS (Standard)       | UDP 53     | tcpdump, dnsmasq log     | Full, plaintext                                |
+| HTTPS / REST         | TCP 443    | tcpdump (SNI), mitmproxy | SNI without decryption, content with mitmproxy |
+| WebSockets           | TCP 443/80 | Wireshark                | Frames decoded if TLS is broken                |
+| mDNS / ZeroConf      | UDP 5353   | tcpdump, tshark          | Full, plaintext                                |
+| SSDP / UPnP          | UDP 1900   | tcpdump                  | Full, plaintext                                |
+| SoundTouch local API | TCP 8090   | tcpdump                  | Full, plaintext (no TLS)                       |
+
+> **Expectation for Bose SoundTouch:** The app likely uses standard DNS (older app generation), REST/HTTPS for the pairing flow with the cloud, WebSockets for push events from the device, and mDNS for local device discovery. The local device API on port 8090 is HTTP without TLS – this traffic is always readable.
+
+---
+
+## Next Steps After Analysis
+
+1. Extract domains from DNS log and SNI → List of all Bose endpoints
+2. HTTP methods and paths from mitmproxy log → Reconstruct API structure
+3. Document auth flow (OAuth2? Proprietary? Token format?)
+4. Build a minimal mock server simulating the critical endpoints
+5. Testing: App against mock server → does pairing work offline?
+
+---
+
+## Appendix A – Generating a Custom CA Certificate
+
+If you don't have a custom DNS server with a CA yet, you can create one directly on the Pi. Alternatively, if you are already using the `soundtouch-service` from this repository, you can reuse its CA certificate located in the `data/certs/` directory.
+
+### 0. (Optional) Copy an Existing CA from another host
+
+If you are already using the `soundtouch-service` on another machine (e.g., your notebook), you can copy the existing CA to the Pi instead of generating a new one:
+
+```bash
+# On your Pi:
+sudo mkdir -p /etc/my-dns-ca
+sudo chown $USER:$USER /etc/my-dns-ca
+
+# Run this on your notebook (replace hostnames and paths):
+# Note: This is easiest if your SSH key is added to the Pi and soundtouch-service host.
+# If you run into permission issues with sudo, ensure the source user has passwordless sudo for 'cat'.
+
+# Step A: Download from source to your notebook
+ssh soundtouch-service "sudo cat /var/lib/soundtouch-service/certs/ca.crt" > ca.crt
+ssh soundtouch-service "sudo cat /var/lib/soundtouch-service/certs/ca.key" > ca.key
+
+# Step B: Upload from notebook to the Pi
+scp ca.crt ca.key soundtouch-access-point:/tmp/
+ssh soundtouch-access-point "sudo mv /tmp/ca.crt /tmp/ca.key /etc/my-dns-ca/ && sudo chown root:root /etc/my-dns-ca/ca.*"
+rm ca.crt ca.key
+```
+
+### 1. Create CA Key and Certificate
+
+```bash
+sudo mkdir -p /etc/my-dns-ca
+cd /etc/my-dns-ca
+
+# Generate CA private key
+sudo openssl genrsa -out ca.key 4096
+
+# Generate Root CA certificate
+# Note: we explicitly add basicConstraints=CA:TRUE for modern TLS clients
+sudo openssl req -x509 -new -nodes -key ca.key -sha256 -days 3650 \
+  -out ca.crt \
+  -subj "/C=DE/O=Bose-Lab/CN=Bose-Lab Root CA" \
+  -addext "basicConstraints=critical,CA:TRUE" \
+  -addext "keyUsage=critical,keyCertSign,cRLSign"
+```
+
+### 2. Generate a Certificate for Interception (Example)
+
+To intercept `global.api.bose.io`, you need a certificate for it, signed by your CA:
+
+```bash
+# Generate server key
+sudo openssl genrsa -out bose.key 2048
+
+# Create CSR (Certificate Signing Request) configuration
+sudo tee bose.ext << 'EOF'
+authorityKeyIdentifier=keyid,issuer
+basicConstraints=CA:FALSE
+keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
+subjectAltName = @alt_names
+
+[alt_names]
+DNS.1 = global.api.bose.io
+DNS.2 = *.bose.io
+EOF
+
+# Generate CSR
+sudo openssl req -new -key bose.key -out bose.csr \
+  -subj "/C=DE/O=Bose-Lab/CN=global.api.bose.io"
+
+# Sign the certificate with your CA
+sudo openssl x509 -req -in bose.csr -CA ca.crt -CAkey ca.key \
+  -CAcreateserial -out bose.crt -days 365 -sha256 -extfile bose.ext
+```
+
+### 3. Usage in your DNS/HTTPS Server
+
+Your custom server (e.g., a small Go or Python script) would then use `bose.crt` and `bose.key` to serve HTTPS traffic for those domains.
+

+# Spotify Account Addition Implementation Status
+
+To fully replace Bose cloud services for the Spotify account addition flow in the "Stockholm" SoundTouch application, the following routes have been implemented in the `soundtouch-service`:
+
+## 1. OAuth Token Exchange (Bose Cloud)
+
+The Stockholm background worker (in `worker_common.js` and `spotify_worker.js`) performs a token exchange using an authorization code.
+
+*   **Route**: `POST /oauth/account/{account}/music/musicprovider/{sourceID}/token/cs`
+*   **Purpose**: To exchange the Spotify authorization code for a Bose-mediated token.
+*   **Implementation**: `HandleBoseAccountToken` in `pkg/service/handlers/handlers_oauth.go`.
+*   **Registration**: Registered in `cmd/soundtouch-service/main.go` under the `/oauth` route group.
+
+## 2. Cloud Source Registration (Marge Service)
+
+The SoundTouch application registers a new music source (e.g., Spotify) with the Bose cloud profile.
+
+*   **Route**: `POST /streaming/account/{account}/source`
+*   **Purpose**: To add the new source (username, credentials, display name) to the user's emulated cloud profile.
+*   **Implementation**: `HandleMargeAddSource` in `pkg/service/handlers/handlers_marge.go`.
+*   **Registration**: Registered in `cmd/soundtouch-service/main.go` under the `/streaming` route group.
+*   **Payload Format**: XML `application/vnd.bose.streaming-v1.1+xml` containing `<source>` with `<username>`, `<sourceproviderid>`, and `<credential type="token_version_3">`.
+
+## 3. Redirect Handling (Browser to App)
+
+The `soundtouch://` deep link redirect URI is handled by the management interface which provides the OAuth callback.
+
+*   **Callback Route**: `GET /mgmt/spotify/callback`
+*   **Implementation**: `HandleMgmtSpotifyCallback` in `pkg/service/handlers/handlers_mgmt.go`.
+*   **Confirmation Route**: `POST /mgmt/spotify/confirm` (used by mobile apps for deep-link codes).
+*   **Implementation**: `HandleMgmtSpotifyConfirm` in `pkg/service/handlers/handlers_mgmt.go`.
+
+## Implementation Details
+
+1.  **Marge Add Source**:
+    *   `HandleMargeAddSource` in `pkg/service/handlers/handlers_marge.go` parses the incoming XML and persists the new source to the `DataStore` for the corresponding account.
+
+2.  **OAuth Account Token Exchange**:
+    *   `HandleBoseAccountToken` in `pkg/service/handlers/handlers_oauth.go` supports the `/oauth/account/.../token/cs` path.
+    *   It responds with a JSON payload including `access_token` and `token_type` "Bearer" after exchanging the code via `ExchangeCodeAndStore`.
+
+3.  **Router Registration**:
+    *   These paths are registered in `cmd/soundtouch-service/main.go` within the `/streaming`, `/oauth`, and `/mgmt` route blocks.

+# Spotify Account Addition Technical Reference
+
+This document details the exact network requests performed by the Bose SoundTouch "Stockholm" application and the SoundTouch speaker when adding a new Spotify account. This information is based on analysis of the Stockholm firmware version `27.0.13-4277-8963611`.
+
+## Flow Overview
+
+1.  **User Authorization Initiation**: The app opens the system browser to Spotify's authorization page.
+2.  **Redirect Handling**: After authorization, Spotify redirects back to the app via a custom URI scheme, delivering an authorization `code`.
+3.  **OAuth Token Exchange**: The app sends this `code` to the background worker, which exchanges it for a Bose-mediated token.
+4.  **Cloud Source Registration**: The app registers the Spotify account as a "source" in the user's Bose Cloud (Marge) profile.
+5.  **Local Device Sync**: The app notifies the local SoundTouch speaker about the new source, which then updates its internal configuration.
+
+---
+
+## 0. User Authorization Initiation
+
+The process begins in the Stockholm UI when the user selects Spotify to add a new account.
+
+### Request Details (App to Browser)
+- **Action**: Open System Browser
+- **Base URL**: `[SPOTIFY_AUTH_URL]` (e.g., `https://accounts.spotify.com/authorize`)
+- **Query Parameters**:
+    - `client_id`: Bose Spotify Client ID
+    - `response_type`: `code`
+    - `redirect_uri`: `http://localhost` (often used as a placeholder or specifically handled by the app's internal webview/proxy)
+    - `scope`: `user-read-private user-read-email ...`
+    - `state`: A base64-encoded JSON object containing metadata, e.g., `{"service": "SPOTIFY"}`.
+
+### Redirect (Browser to App)
+Upon successful login and authorization, Spotify redirects the browser to a URL that the SoundTouch app intercepts.
+
+- **URL Format**: `soundtouch://bose/musicservice/spotify/login?code=[AUTH_CODE]&state=[STATE]`
+- **App Action**: The `UIMain` component (in `ui_main.js`) handles this "deep link". It extracts the `code` from the query parameters and prepares to send it to the background worker.
+
+---
+
+## 1. OAuth Token Exchange (Bose Cloud)
+
+After the UI intercepts the redirect and extracts the `code`, it sends a `createOAuthAccountRequest` to the background `SpotifyWorker`. The worker then performs the exchange for a Bose-mediated token.
+
+### What is a "Bose-mediated token"?
+The "Bose-mediated token" is a token issued by the Bose OAuth proxy. When the app (or device) requests a token via `oauth.streaming.bose.com`, Bose's service performs the actual OAuth2 exchange with Spotify.
+
+- **It is not directly a Spotify refresh token**: Instead, it is a Bose-issued token that *represents* the underlying Spotify session.
+- **Token Version 3**: Modern firmware uses `token_version_3`, which signifies that the device doesn't store the raw Spotify tokens but instead uses a Bose-specific "secret" that the Bose Cloud uses to fetch fresh Spotify access tokens on the device's behalf.
+- **Access vs Refresh**: The initial response from the `.../token/cs` endpoint typically contains an `access_token` (valid for ~1 hour) and a `token_type: "Bearer"`. The Bose cloud service manages the persistent refresh token internally.
+
+### Internal Message (UI to Worker)
+- **Message Type**: `createOAuthAccountRequest`
+- **Payload**:
+    ```json
+    {
+      "source": "SPOTIFY",
+      "code": "[AUTH_CODE_FROM_REDIRECT]",
+      "credentialType": "token_version_3"
+    }
+    ```
+
+### Outgoing Request (Worker to Bose OAuth Proxy)
+- **Endpoint**: `https://oauth.streaming.bose.com/oauth/account/[ACCOUNT_ID]/music/musicprovider/15/token/cs`
+- **Method**: `POST`
+- **Headers**:
+    - `Content-Type: application/json`
+    - `Accept: application/json`
+    - `Authorization: Bearer [SESSION_TOKEN]` (The user's Bose account session token)
+
+### Payload (JSON)
+```json
+{
+  "grant_type": "authorization_code",
+  "code": "[AUTH_CODE_FROM_SPOTIFY]",
+  "redirect_uri": "http://localhost"
+}
+```
+
+### curl Example
+```bash
+curl -X POST "https://oauth.streaming.bose.com/oauth/account/[ACCOUNT_ID]/music/musicprovider/15/token/cs" \
+     -H "Content-Type: application/json" \
+     -H "Authorization: Bearer [SESSION_TOKEN]" \
+     -d '{
+       "grant_type": "authorization_code",
+       "code": "[AUTH_CODE_FROM_SPOTIFY]",
+       "redirect_uri": "http://localhost"
+     }'
+```
+
+---
+
+## 2. Cloud Source Registration (Marge)
+
+The app now registers the Spotify account with the Bose "Marge" service. This makes the source available across all devices linked to the same Bose account.
+
+### Request Details
+- **Endpoint**: `https://streaming.bose.com/streaming/account/[ACCOUNT_ID]/source`
+- **Method**: `POST`
+- **Headers**:
+    - `Content-Type: application/vnd.bose.streaming-v1.1+xml`
+    - `Authorization: [MARGE_TOKEN]`
+    - `GUID: [DEVICE_GUID]`
+    - `ClientType: Stockholm`
+
+### Payload (XML)
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<source>
+    <username>[SPOTIFY_USER_ID]</username>
+    <sourceproviderid>15</sourceproviderid>
+    <credential type="token_version_3">[SECRET_TOKEN_OBTAINED_IN_STEP_1]</credential>
+    <sourcename>[DISPLAY_NAME_E_G_EMAIL]</sourcename>
+</source>
+```
+
+### curl Example
+```bash
+curl -X POST "https://streaming.bose.com/streaming/account/[ACCOUNT_ID]/source" \
+     -H "Content-Type: application/vnd.bose.streaming-v1.1+xml" \
+     -H "Authorization: [MARGE_TOKEN]" \
+     -d '<?xml version="1.0" encoding="UTF-8"?><source><username>[USER]</username><sourceproviderid>15</sourceproviderid><credential type="token_version_3">[TOKEN]</credential><sourcename>[NAME]</sourcename></source>'
+```
+
+---
+
+### Local Device Sync (LISA API)
+
+The app notifies the physical SoundTouch speaker about the new source. This is usually done via the device's management API on port 8090.
+
+#### Modern Flow (OAuth)
+- **Endpoint**: `http://[DEVICE_IP]:8090/setMusicServiceOAuthAccount`
+- **Method**: `POST`
+- **Payload**:
+```xml
+<OAuthCredentials source="SPOTIFY" displayName="[DISPLAY_NAME]">
+    <user>[SPOTIFY_USER_ID]</user>
+    <code>[AUTH_CODE_OR_TOKEN]</code>
+    <version>token_version_3</version>
+</OAuthCredentials>
+```
+
+#### Marge-Sync Notification (Fall-back)
+If the speaker returns `1029 UNKNOWN_ACTION_ERROR`, it signifies the LISA API version is too old for the OAuth flow. Stockholm-based firmware often expects the account to be registered in Marge first, followed by a notification to sync.
+- **Endpoint**: `http://[DEVICE_IP]:8090/notification`
+- **Method**: `POST`
+- **Payload**:
+```xml
+<updates deviceID="[DEVICE_UID]">
+    <sourcesUpdated></sourcesUpdated>
+</updates>
+```
+
+#### Legacy Flow (Fall-back)
+For older firmware that doesn't use Marge for Spotify:
+- **Endpoint**: `http://[DEVICE_IP]:8090/setMusicServiceAccount`
+- **Method**: `POST`
+- **Payload**:
+```xml
+<credentials source="SPOTIFY" displayName="Spotify Premium">
+    <user>[USER]</user>
+    <pass>[TOKEN]</pass>
+</credentials>
+```
+
+---
+
+## Implementation in SoundTouch-Service
+
+This project implements the "Bose-mediated token" flow as follows:
+
+1.  **Surrogate Secrets**: When a user links their Spotify account via `soundtouch-service`, the service generates a 32-character hex string (a "Bose Secret").
+2.  **Marge & LISA registration**: This secret is sent to the speaker and stored in the emulated Marge cloud as the `credential`. The raw Spotify refresh token never leaves the server.
+3.  **Token Refresh Proxy**: When the speaker needs a fresh Spotify `access_token`, it calls the `soundtouch-service` proxy (`/oauth/device/.../token/cs3`) providing this secret. The server maps the secret back to the actual Spotify account, performs the refresh with Spotify, and returns a fresh short-lived `access_token` to the speaker.
+
+---
+
+## Placeholders and Constants
+
+| Placeholder       | Description                                         |
+|:------------------|:----------------------------------------------------|
+| `[ACCOUNT_ID]`    | The internal Bose account ID (UUID).                |
+| `[SESSION_TOKEN]` | Temporary token from Bose login.                    |
+| `[MARGE_TOKEN]`   | Persistent authorization token for Marge services.  |
+| `[DEVICE_GUID]`   | Unique identifier for the controller app instance.  |
+| `[DEVICE_IP]`     | Local IP address of the SoundTouch speaker.         |
+| `15`              | Constant `sourceproviderid` for Spotify.            |
+| `token_version_3` | Credential type for modern OAuth2 Spotify accounts. |
+
+---
+
+## Resulting Persistence
+
+Once these requests succeed, the device updates its `/mnt/nv/BoseApp-Persistence/1/Sources.xml` file:
+
+```xml
+<source displayName="user@example.com" secret="[SECRET_BLOB]" secretType="token_version_3">
+    <sourceKey type="SPOTIFY" account="user" />
+</source>
+```
