docs(amazon): confirm amazon_music:access scope requires device client ID

Attempting to request amazon_music:access with a standard application
client ID (amzn1.application-oa2-client.*) returns HTTP 400
lwa-invalid-parameter-bad-scope from the LWA authorization endpoint.
The scope is gated to Amazon Music partner device client IDs.

Revert scope to "profile" (working state) and document the confirmed
blocker with the exact error. Path forward: Amazon Music partner
registration for a device client ID; one-line change to AmazonScopes
when available.

 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.

+# 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.

 *   **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>`.

 *   **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.

 *   **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.

+*   **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.

+# 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.

+| **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).

+# Bose SoundTouch Traffic Interception Runbook
+
+Intercept HTTPS/WebSocket traffic from the Bose SoundTouch Android app using an Android emulator, mitmproxy, and Frida. Tested on Apple Silicon (ARM64) Mac.
+
+## Prerequisites
+
+- Android Studio installed (for SDK tools and emulator)
+- Docker installed
+- mitmproxy installed (`pip install mitmproxy` or via your preferred method)
+- The Bose SoundTouch APK (extracted from a real device, see below)
+
+Add Android SDK tools to your PATH (add to `~/.zshrc`):
+
+```bash
+export PATH=$PATH:~/Library/Android/sdk/emulator
+export PATH=$PATH:~/Library/Android/sdk/platform-tools
+```
+
+---
+
+## 1. Extract APK from Real Device
+
+Connect your Android device via USB with USB debugging enabled.
+
+```bash
+adb devices
+# 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

+
+## 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.
+
+## Appendix B – Helpful Commands
+
+```bash
+# Which IPs did the phone receive?
+cat /var/lib/misc/dnsmasq.leases
+
+# Is the access point active?
+sudo systemctl status hostapd
+
+# Is dnsmasq active?
+sudo systemctl status dnsmasq
+
+# Check interfaces and IPs
+ip addr show
+
+# Check routing table
+ip route show
+
+# Show active nftables rules
+sudo nft list ruleset
+
+# All running tcpdump processes
+pgrep -a tcpdump
+
+# Test the Pi's own DNS resolution
+dig @127.0.0.1 -p 5353 global.api.bose.io
+
+# Check network connectivity from the phone (from the Pi)
+ping 192.168.10.101   # Phone IP from dnsmasq.leases
+```

+# 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.

+# Bose SoundTouch — Community Tools for Post-EOL Preservation

+> **Context:** Bose announced the shutdown of SoundTouch cloud services, extended to **May 6, 2026**. On that date the official SoundTouch app will update to a local-only version. Bose has released the [SoundTouch Web API documentation](https://assets.bosecreative.com/m/496577402d128874/original/SoundTouch-Web-API.pdf) as open-source to enable community-driven development. This document surveys the active community projects, their feature coverage, and open development opportunities.

+
+## What Bose Is Doing
+
+After the May 6, 2026 shutdown, the following will **continue to work**:
+
+- Streaming via Bluetooth, AirPlay, Spotify Connect, and AUX
+- Local device control and grouping via an updated SoundTouch app
+- Remote control features (play, pause, skip, volume)
+- HDMI/optical connections on soundbars
+
+The following will **stop working**:
+
+- Physical and app-based presets
+- In-app music service browsing (TuneIn, Pandora, etc.)
+- Stereo pairing for SoundTouch 10
+- Security and firmware updates

+
+A reverse-engineered intercept API that replaces the Bose cloud servers locally. Works by redirecting the speaker's internal `SoundTouchSdkPrivateCfg.xml` to a self-hosted FastAPI server, emulating the `marge` server (required for basic network functionality) and the `bmx` server (required for TuneIn). Deployable as a Docker container or systemd daemon. The most community-engaged project, with a dedicated discussion thread tracking Bose cloud service status.

+A self-hosted private cloud that emulates and replaces the Bose Cloud Service. Runs locally on a NAS or PC, intercepts the complex server handshakes needed to keep the SoundTouch infrastructure functional. Relies on **Music Assistant** for backend audio routing and provider aggregation. Features a setup wizard including USB config generation (`OverrideSdkPrivateCfg.xml`) and an on-screen Bose Cloud Emulation Setup guide. Targets users who want the broadest streaming provider support via Music Assistant's ecosystem.

+
+The most comprehensive single toolkit in the ecosystem. Comprises three components: a Go library (importable package), a CLI (`soundtouch-cli`), and a local cloud emulation service (`soundtouch-service`). Covers the widest range of dimensions of any single project. Implements the complete Bose Spotify OAuth relay including surrogate secret generation and token refresh proxy. Includes a built-in DNS server for device redirection without SSH, HTTPS/custom CA injection, HTTP session recording, traffic proxy/logging, and a web management UI. Tested on real SoundTouch 10 and 20 hardware. Has a Patreon for ongoing support.

+
+A Java-based middleware that hosts the original Bose Stockholm frontend (extracted from the APK) in a local web browser at `http://127.0.0.1:8088/`. Bridges the Stockholm UI to local speakers via an HTTP proxy that resolves cross-origin issues, with SSDP-based device discovery and JSON state persistence. Unlike every other tool in the ecosystem, it runs the **official Bose UI** rather than a custom replacement — preserving the familiar Bose UX at the cost of requiring the Stockholm APK. Notable limitations: OAuth flows are unreliable, and WebSocket connections to speakers over HTTPS have blocking issues. Works alongside soundcork's backend for full cloud emulation.

+## Making AfterTouch the One-Stop Solution — Open Tasks
+
+AfterTouch is the strongest single project across the service and developer layers. Its remaining gaps are on the consumer-facing and ecosystem-integration sides.
+
+### Priority 1 — PWA installability
+
+The web UI is already fully responsive — it has Bootstrap grid columns, `@media (max-width: 768px)` and `@media (max-width: 576px)` breakpoints, and a proper viewport meta tag. It works on iPhone and Android browsers today. What's missing is **installability**: no `manifest.json` and no service worker, so it cannot be added to the home screen as a standalone app. Adding these would close the iOS app gap ecosystem-wide (no project has an iOS app) at minimal effort.
+
+### Priority 2 — RadioBrowser as a first-class provider
+
+AfterTouch can proxy and play any stream URL, but there is no built-in station search. OpenCloudTouch's RadioBrowser integration is the reference. Tasks:
+- Wire the [RadioBrowser API](https://www.radio-browser.info/) into the `soundtouch-web` web UI as a browsable/searchable source.
+- Make discovered stations directly presetable to hardware buttons.
+- This is the most common replacement for TuneIn for users who listened to internet radio via presets.
+
+### Priority 3 — Raspberry Pi SD card image
+
+OpenCloudTouch ships a flashable Pi image and it dramatically lowers the barrier for the most common "always-on local server" deployment. AfterTouch already has Docker and a web management UI; this is largely a CI/packaging task:
+- Build a Pi image (using e.g. `pi-gen` or `rpi-imager`-compatible tooling) that boots directly into `soundtouch-service`.
+- Auto-starts on boot, auto-discovers devices, opens the web UI on a known port.
+- Target Pi 3/4/5 with amd64/arm64/arm/v7 variants (mirroring OCT's approach).
+
+### Priority 4 — USB config generation in the web UI
+
+AfterTouch modifies `SoundTouchSdkPrivateCfg.xml` via SSH (`pkg/service/setup/setup.go`) and documents the redirect process thoroughly, but does not yet generate the USB stick content for users without SSH access. A "prepare USB stick" button in the web UI would remove the last manual step:
+- Generate `OverrideSdkPrivateCfg.xml` pre-populated with the running server's URL.
+- Optionally include the custom CA certificate for HTTPS-capable devices.
+- Surface alongside the existing guided migration wizard.
+
+### Priority 5 — Music Assistant integration
+
+SoundTouch Hybrid 2026 uses Music Assistant as its streaming backend, giving access to Apple Music, Deezer, local libraries, and many other providers. A formal Music Assistant **player provider** for AfterTouch would give power users a path to sources beyond Spotify, TuneIn, Pandora, and RadioBrowser. The Music Assistant community has an open discussion thread on this ([#4766](https://github.com/orgs/music-assistant/discussions/4766)).
+
+### Priority 6 — DNS-based migration documentation
+
+AfterTouch includes a built-in DNS server (`ENABLE_DNS_DISCOVERY`, `DNS_BIND_ADDR`, `DNS_UPSTREAM`) that intercepts `*.bose.com` queries and forwards everything else upstream — no Pi-hole, AdGuard, or any other external tool required. The ResolvConf migration path already treats DNS as a first-class option. The remaining gap is awareness: users unfamiliar with the project may not realise no external DNS infrastructure is needed. Tasks:
+- Surface the built-in DNS server more prominently in the getting-started documentation.
+- Document Pi-hole / AdGuard Home as an *alternative* for users who already run those, not a requirement.
+
+### Priority 7 — MQTT integration
+
+A design document exists (`docs/guides/MQTT-INTEGRATION-DESIGN.md`) but no code has been written. Implementing it would unlock home automation use cases without requiring the full Home Assistant stack — enabling triggers like "play preset 1 when front door opens" via any MQTT-capable automation platform.

+soundcork and AfterTouch share the most functional overlap of any two projects in the ecosystem. For the implementation-level parity analysis and remaining tasks see [docs/PARITY-SOUNDCORK.md](../PARITY-SOUNDCORK.md).
+
+### Architectural differences (not gaps)
+
+These exist in soundcork but are deliberate architectural choices in AfterTouch, not missing features:

+
+
+
+### Ecosystem fragmentation vs. convergence
+
+The community is currently covering different parts of the problem in parallel rather than converging. AfterTouch explicitly credits soundcork, Überböse, and SoundTouch Plus in its README and describes its `soundtouch-service` as "heavily inspired by SoundCork". There is an opportunity — and arguably a need — for these projects to formally coordinate: shared test fixtures, a common compatibility matrix against specific firmware versions, and agreed-on API contracts would all reduce duplicated effort.
+
+### Firmware version sensitivity
+
+The SoundTouch 10 is most dependent on Marge for basic network functionality; the 20 and 30 are somewhat more tolerant. Compatibility across firmware versions is not systematically documented anywhere. A community firmware compatibility matrix (model × firmware version × which emulation features work) would be high value and is currently missing.
+
+### Security posture
+
+All projects warn that speakers should only be used on a private, firewalled network after cloud shutdown. AfterTouch is the only project to implement HTTPS/custom CA, which matters if devices are ever on a network where traffic could be inspected. soundcork's SECURITY.md explicitly warns against running on open networks.
+
+### No iOS app — a structural gap
+
+The original SoundTouch app was iOS-first. Every community replacement is Android-only (Überböse App) or browser-based. This is the largest unaddressed user segment in the ecosystem.
+
+### Bose's open-source move as a precedent
+
+Bose's decision to release API documentation rather than simply shutting down is notable — it mirrors what Pebble users did themselves with Rebble after that shutdown, but here the manufacturer initiated it. This sets a useful precedent and gives the community a solid legal and technical foundation to build on.

+# Amazon Music OAuth Integration
+
+This document describes the plan and specification for adding Amazon Music OAuth support to the SoundTouch service, enabling continued Amazon Music playback after the Bose cloud shutdown (May 2026).
+
+The implementation mirrors the [Spotify OAuth integration](spotify-oauth.md) closely. Read that document first — this one calls out only the differences.
+
+## Status
+
+**Infrastructure complete — streaming blocked by API access.**
+
+All eight implementation steps are done. The OAuth flow (account linking, token storage, token refresh) works end-to-end with a standard Login with Amazon app. Token exchange (`/oauth/device/.../token/cs1`) succeeds and the speaker receives a valid `Atza|` access token.
+
+However, real-world testing shows that the speaker then calls `https://music-api.amazon.com/` with that token and receives a `401 Unauthorized` (no redirect to a regional endpoint). This means the token does not carry the scopes required to access the Amazon Music streaming API.
+
+**Root cause (confirmed):** Amazon Music streaming requires the `amazon_music:access` scope, which is only available to **device client IDs** — a separate credential type obtained through Amazon's Music partner programme. Standard Login with Amazon application client IDs (`amzn1.application-oa2-client.*`) cannot request this scope: attempting to include it in the authorization URL returns `lwa-invalid-parameter-bad-scope` (HTTP 400) from the LWA authorization endpoint. Bose would have held a device client ID as a registered Amazon Music partner.
+
+**What still works:**
+- Account linking and token storage
+- Token refresh (the service correctly exchanges the refresh token for a fresh access token)
+- Marge source registration (the speaker sees Amazon Music as a configured source)
+
+**What does not work:**
+- Actual music playback — the speaker's `AmazonClient` cannot authenticate to `music-api.amazon.com` with a standard LWA token
+
+**Path forward:** Obtaining a device client ID requires registering with Amazon's Music partner programme. If such a credential is obtained, the only code change needed is swapping the `client_id`/`client_secret` for the device credentials and adding `amazon_music:access` to `AmazonScopes` in `pkg/service/amazon/service.go` — everything else is already in place. The `site_id` field is a secondary open question that may also affect regional routing once the scope issue is resolved.
+
+---
+
+## Secret Format (confirmed from a live Bose system)
+
+A real Amazon source entry from a migrated device's `Sources.xml`:
+
+```xml
+<source secretType="token">
+    <credential type="token">{"AmazonSecret":{"refresh_token":"Atzr|...","site_id":"1464855981"}}</credential>
+    <sourceKey type="AMAZON" account="user@example.com"/>
+</source>
+```
+
+Key observations:
+
+- **Secret envelope**: `{"AmazonSecret":{"refresh_token":"...","site_id":"..."}}` — JSON-encoded, HTML-entity-escaped in XML attributes, stored as the credential value.
+- **`Atzr|` prefix**: This is the standard Amazon LWA (Login with Amazon) refresh token prefix from the **authorization code grant** — confirming that Web OAuth is the correct flow, not CBL.
+- **`site_id`**: A numeric string (`"1464855981"`). Origin is not yet fully confirmed; candidates are:
+  - A static Bose partner identifier baked into the Bose app/firmware (same value for all users), or
+  - A per-user Amazon Music identifier returned by a Music API device registration call.
+  - Needs verification — possibly obtained by calling the Amazon Music API after initial authentication.
+- **`account` field**: The user's Amazon email address (obtained from the LWA `/user/profile` endpoint).
+
+When `HandleBoseAmazonToken` receives a refresh request from the speaker, it must:
+1. Parse the `AmazonSecret` JSON from the stored credential to extract `refresh_token`.
+2. Call the LWA token endpoint with a `refresh_token` grant.
+3. Return the fresh `access_token` to the speaker.
+4. Persist the rotated `refresh_token` back into the `AmazonSecret` envelope.
+
+---
+
+## How the Speaker Uses This
+
+When the SoundTouch firmware tries to play Amazon Music after migration, it sends a token refresh request to the local service:
+
+```
+POST /oauth/device/{deviceID}/music/musicprovider/20/token/cs1
+```
+
+The service must respond with a fresh Amazon access token. The speaker then uses that token directly with Amazon's playback infrastructure.
+
+The `cs1` suffix (credential schema 1) is Amazon-specific; Spotify uses `cs3`. This route is already registered.
+
+> **DNS note:** The speaker constructs the OAuth hostname by appending `oauth` to the streaming service subdomain. If the service is reachable at `myhost.local`, the speaker will call `myhostoauth.local`. A DNS alias pointing `myhostoauth.<domain>` to the same IP as the service is required.
+

+
+---
+
+## Implementation Steps
+
+### Step 1 — Extract ZeroConf into a shared package
+
+**Why first:** The DH-blob encryption in `pkg/service/spotify/zeroconf.go` is entirely provider-agnostic. Extracting it to `pkg/service/zeroconf/` before adding Amazon avoids duplicating ~200 lines of crypto code.
+
+**What changes:**
+- Create `pkg/service/zeroconf/zeroconf.go` — move `generateDHKeyPair`, `computeSharedSecret`, `deriveKeys`, `buildCredentialsBlob`, `encryptBlob` and helpers. Expose `authType` as a parameter (Spotify and Amazon both use `AuthTypeOAuthToken = 4`, but this makes it explicit).
+- Update `pkg/service/spotify/zeroconf.go` — delete moved code; `PushSpotifyCredentials` becomes a one-line wrapper calling `zeroconf.PushCredentials(...)`.
+
+### Step 2 — Create `pkg/service/amazon/service.go`
+
+Mirror `pkg/service/spotify/service.go`. The `Account` struct is identical; copy it unchanged.
+
+**Amazon-specific differences:**
+
+| Item                      | Spotify                                  | Amazon                                          |
+|---------------------------|------------------------------------------|-------------------------------------------------|
+| Authorization URL         | `https://accounts.spotify.com/authorize` | `https://www.amazon.com/ap/oa`                  |
+| Token endpoint            | `https://accounts.spotify.com/api/token` | `https://api.amazon.com/auth/o2/token`          |
+| Profile endpoint          | `https://api.spotify.com/v1/me`          | `https://api.amazon.com/user/profile`           |
+| Token request credentials | HTTP Basic Auth (clientID:clientSecret)  | POST body fields `client_id` / `client_secret`  |
+| Profile fields            | `id`, `display_name`, `email`            | `user_id`, `name`, `email`                      |
+| Scopes                    | `streaming user-read-private ...`        | `profile` (expand to `music::*` when available) |
+| Entity resolution         | `ResolveEntity()` via Spotify API        | Not implemented (API in closed beta)            |
+
+Accounts persist to `{dataDir}/amazon/accounts.json`.
+
+The token request credential difference (body vs. Basic Auth) is the most important implementation detail.
+
+### Step 3 — Create `pkg/service/amazon/zeroconf.go`
+
+A single exported function `PushAmazonCredentials(zcBaseURL, username, accessToken string) error` delegating to the shared `zeroconf.PushCredentials(...)`.
+
+### Step 4 — Implement `HandleBoseAmazonToken`
+
+Replace the 501 stub in `pkg/service/handlers/handlers_oauth.go` with the full mirror of `HandleBoseSpotifyToken`:
+- Parse body for `refresh_token` / `code`
+- Look up account by BoseSecret; refresh and return token
+- Fall back to first account via `GetFreshToken()` if no matching account
+- Fall back to `HandleBoseProxy` if no Amazon service is configured
+- **Omit `scope` from the response** — Amazon Music scopes are undocumented; sending invented values risks firmware rejection
+
+### Step 5 — Add Amazon fields to `Server`
+
+In `pkg/service/handlers/server.go`, add alongside the Spotify fields:
+
+```go
+amazonClientID     string
+amazonClientSecret string
+amazonRedirectURI  string
+amazonService      *amazon.Service
+```
+
+Add methods: `SetAmazonConfig`, `SetAmazonService`, `IsAmazonConfigured`, `PrimeDeviceWithAmazon`.
+
+### Step 6 — Add management handlers
+
+In `pkg/service/handlers/handlers_mgmt.go`, add six handlers mirroring Spotify:
+
+| Handler                       | Notes                                   |
+|-------------------------------|-----------------------------------------|
+| `HandleMgmtAmazonInit`        | Returns LWA authorize URL               |
+| `HandleMgmtAmazonCallback`    | No auth; calls `bridgeAmazonToMarge`    |
+| `HandleMgmtAmazonConfirm`     | Basic Auth; calls `bridgeAmazonToMarge` |
+| `HandleMgmtAmazonAccounts`    | Returns account list (tokens stripped)  |
+| `HandleMgmtAmazonToken`       | Returns fresh access token              |
+| `HandleMgmtPrimeDeviceAmazon` | Pushes token to speaker via ZeroConf    |
+
+`bridgeAmazonToMarge` must encode the stored secret as `{"AmazonSecret":{"refresh_token":"<token>","site_id":"<id>"}}` and use `CredentialTypeToken` ("token") — **not** `CredentialTypeTokenV3`. Amazon uses `cs1` semantics.
+
+### Step 7 — Wire CLI flags and router
+
+**`main.go` flags** (env vars in parentheses):
+- `--amazon-client-id` (`AMAZON_CLIENT_ID`)
+- `--amazon-client-secret` (`AMAZON_CLIENT_SECRET`)
+- `--amazon-redirect-uri` (`AMAZON_REDIRECT_URI`, default: `ueberboese-login://amazon`)
+- `--amazon-token-url` (`AMAZON_TOKEN_URL`, for testing overrides)
+- `--amazon-profile-url` (`AMAZON_PROFILE_URL`, for testing overrides)
+
+**Router** (`setupRouter`): Add `/mgmt/amazon/*` sub-routes next to the Spotify block. The `/oauth/.../token/cs1` route is already registered and dispatches to `HandleBoseAmazonToken`.
+
+**`pkg/service/marge/marge.go`**: Extend the `AddSource` provider-label branch to map `AmazonProviderID (20) → "AMAZON"` so stored sources carry the correct type string rather than the raw numeric ID.
+
+**`pkg/models/account.go`**: Add `NewAmazonOAuthCredentials` with `Source: "AMAZON"`, `Version: "token"`.
+
+### Step 8 — Tests
+
+Mirror the Spotify test suite for the Amazon package:
+
+- `TestBuildAuthorizeURL` — verify LWA URL structure
+- `TestExchangeCodeAndStore` — mock token + profile servers; assert POST body credentials (not Basic Auth)
+- `TestRefreshAccessToken` — verify body credentials, token rotation
+- `TestGetFreshToken*` — copy Spotify variants verbatim
+- `TestSaveAndLoad` — verify persistence under `amazon/accounts.json`
+
+Add `pkg/testutils/amazon/handlers.go` and `tests/integration/mocks/amazon.go` mock servers mirroring the Spotify equivalents.
+
+Update `cmd/soundtouch-service/testdata/router_routes.txt` snapshot after wiring.
+
+---
+
+## Trying It Out
+
+### 1. Create a Login with Amazon (LWA) app
+
+Go to [developer.amazon.com](https://developer.amazon.com) → **Login with Amazon** → **Create a New Security Profile**.
+
+You will receive a **Client ID** and **Client Secret**. Under *Web Settings*, add an **Allowed Return URL** that matches `--amazon-redirect-uri`:
+
+- **Browser flow** (easiest to test): `http://<your-host>:8000/mgmt/amazon/callback`
+- **Mobile deep-link flow**: `ueberboese-login://amazon` (the default)
+
+The `profile` scope is sufficient — `music::` scopes are in closed beta and not required. The service only brokers tokens; the speaker communicates with Amazon's playback infrastructure directly.
+
+### 2. Start the service
+
+```bash
+./soundtouch-service \
+  --amazon-client-id  amzn1.application-oa2-client.xxx \
+  --amazon-client-secret yyy \
+  --amazon-redirect-uri http://<your-host>:8000/mgmt/amazon/callback
+```
+
+Or set the equivalent environment variables: `AMAZON_CLIENT_ID`, `AMAZON_CLIENT_SECRET`, `AMAZON_REDIRECT_URI`.
+
+### 3. Trigger the OAuth flow
+
+```bash
+# Get the LWA authorization URL
+curl -u admin:change_me! -X POST http://localhost:8000/mgmt/amazon/init
+# → {"redirectUrl":"https://www.amazon.com/ap/oa?client_id=...&scope=profile&..."}
+```
+
+Open the `redirectUrl` in a browser, log in with your Amazon account, and authorize the app. Amazon redirects back to `/mgmt/amazon/callback`, which responds with an HTML page saying "Amazon Music Connected".
+
+### 4. Verify the account is linked
+
+```bash
+curl -u admin:change_me! http://localhost:8000/mgmt/amazon/accounts
+# → {"accounts":[{"user_id":"amzn1.account.xxx","display_name":"Your Name","email":"you@example.com",...}]}
+```
+
+### 5. Prime a speaker
+
+```bash
+# Discover device IDs first
+curl -u admin:change_me! http://localhost:8000/mgmt/accounts/default/speakers
+
+# Push the token to a specific speaker via ZeroConf
+curl -u admin:change_me! -X POST \
+  "http://localhost:8000/mgmt/amazon/prime?deviceId=<deviceId>"
+# → {"status":"Priming triggered"}
+```
+
+### 6. Verify token refresh from the speaker
+
+Once a speaker has Amazon Music as a source, it will periodically POST to:
+
+```
+POST /oauth/device/{deviceID}/music/musicprovider/20/token/cs1
+```
+
+The service looks up the account by refresh token, refreshes it via LWA, and returns a fresh `access_token`. Check the service logs for `[Amazon]` entries confirming this flow.
+
+### DNS requirement
+
+The speaker derives the OAuth hostname by appending `oauth` to its configured streaming subdomain. If the service is at `myhost.local`, the speaker calls `myhostoauth.local`. A DNS alias pointing `myhostoauth.<domain>` to the same IP is required — the built-in DNS discovery server handles this automatically when `--dns-discovery` is enabled.
+
+### Open question: `site_id`
+
+The `AmazonSecret` credential envelope contains a `site_id` field (e.g. `"1464855981"` seen in a real migrated device). Its origin is unconfirmed — it may be a static Bose partner ID or a per-user Amazon Music identifier. The service currently stores an empty string.
+
+Real-world testing shows the device's `AmazonClient` calls `CheckBaseUrlRedirect` with empty `data` (the `site_id`) and then tries `https://music-api.amazon.com/` directly, receiving a 401 with no redirect to a regional endpoint (e.g. `music-api.amazon.de` for a German account). This suggests that:
+
+1. A correct `site_id` might cause the device to use the right regional endpoint instead of the US default.
+2. Even so, the token scope issue (see Status above) would still block playback — resolving `site_id` alone is not sufficient.
+
+`site_id` is likely secondary to the partner scope problem. It remains an open question for the post-scope-resolution phase.
+
+---
+

+| `POST` | `/mgmt/amazon/confirm`                                      | Basic | Mobile app confirm (deep link delivers code)       |
+| `GET`  | `/mgmt/amazon/accounts`                                     | Basic | List linked Amazon accounts (tokens stripped)      |
+| `GET`  | `/mgmt/amazon/token`                                        | Basic | Get fresh access token (auto-refreshes if expired) |
+| `POST` | `/mgmt/amazon/prime`                                        | Basic | Push token to speaker via ZeroConf                 |
+
+## Security
+
+Same model as Spotify:
+- `/mgmt/amazon/callback` is intentionally outside Basic Auth to allow direct redirects from Amazon's authorization server.
+- All other `/mgmt/*` endpoints require Basic Auth.
+- Accounts persist to `{dataDir}/amazon/accounts.json` with `0600` permissions.
+- `GetAccounts` strips `AccessToken` and `RefreshToken` from responses.
+
+## Key Design Decisions
+
+**Secret is a JSON envelope, not a bare token.** The stored credential is `{"AmazonSecret":{"refresh_token":"Atzr|...","site_id":"..."}}`, HTML-entity-escaped when written to XML attributes. This was confirmed from a real migrated device's `Sources.xml`. `HandleBoseAmazonToken` must parse this structure to extract the `refresh_token`, and `bridgeAmazonToMarge` must produce it when storing after OAuth.
+
+**`site_id` origin is unconfirmed.** It may be a static Bose partner ID or a per-user Amazon Music identifier. Needs verification — likely obtained by calling the Amazon Music API or the LWA profile endpoint post-authentication.
+
+**Credential type is `token`, not `token_version_3`.** `CredentialTypeTokenV3` is Spotify-specific (`cs3`). Amazon uses `cs1`, which maps to the plain `CredentialTypeToken` ("token") constant. Do not upgrade Amazon credentials to v3 in `marge.go`.
+
+**POST body credentials, not Basic Auth.** The Amazon LWA token endpoint (`/auth/o2/token`) expects `client_id` and `client_secret` as POST body fields, not as an HTTP Basic Auth header. This is the single most important difference from the Spotify implementation.
+
+**No entity resolution.** `ResolveEntity()` is not implemented for Amazon — the Amazon Music API is in closed beta. Return HTTP 501 if an entity endpoint is ever requested.
+
+**`scope` omitted from token response.** The Spotify handler returns a hardcoded scope string. Amazon Music scopes for playback are undocumented; returning an empty or absent `scope` is safer than inventing values.
+
+**ZeroConf extraction is a prerequisite.** The DH-blob crypto in `spotify/zeroconf.go` should be extracted to a shared package before Amazon is added to avoid duplicating cryptographic code.

 ## Overview
 
-To enable Spotify Connect for SoundTouch devices, especially for remote availability outside the local network, the speaker must be associated with a Spotify account via a process called "priming." This involves sending an `addUser` command to the speaker's ZeroConf API (port 8200) containing a valid Spotify username and OAuth access token.
+To enable Spotify Connect for SoundTouch devices, especially for remote availability outside the local network, the speaker must be associated with a Spotify account via a process called "priming." This involves a two-step exchange with the speaker's ZeroConf API (port 8200):
+
+1. **`getInfo`** — retrieve the speaker's Diffie-Hellman public key and device metadata.
+2. **`addUser`** — push encrypted Spotify credentials using the shared DH secret.
+
+This is the standard Spotify Connect ZeroConf protocol. Once the speaker holds a properly encrypted credential blob it can independently authenticate with Spotify's servers and refresh its own session without any further involvement from AfterTouch.
+
+### ZeroConf Protocol
+
+The current implementation follows the full Spotify Connect ZeroConf protocol (`pkg/service/spotify/zeroconf.go`):
+
+1. `GET http://{ip}:8200/zc?action=getInfo` → parse `publicKey` (base64 DH key, 768-bit Oakley Group 1 prime) from the response.
+2. Generate a client DH key pair using the same group parameters.
+3. Compute `sharedSecret = DH(clientPrivate, speakerPublicKey)`.
+4. Derive keys: `baseKey = SHA1(sharedSecret)[:16]`, then HMAC-SHA1 with labels `"encryption"` and `"checksum"`.
+5. Encrypt a protobuf-encoded `LoginCredentials` blob (username, `AUTHENTICATION_SPOTIFY_TOKEN=4`, access token) using AES-128-CTR + HMAC-SHA1 checksum.
+6. `POST http://{ip}:8200/zc?action=addUser` with `blob={encryptedBlob}`, `clientKey={clientPublicKeyBase64}`.
+
+The speaker decrypts the blob, stores long-lived credentials, and can handle token refresh with Spotify independently. No periodic re-priming is required for token expiry.
+
+The algorithm is based on [librespot](https://github.com/librespot-org/librespot) (Rust reference implementation).
+
+### Fallback for Older Firmware
+
+If `getInfo` fails (e.g. firmware that does not implement the DH exchange), `PushSpotifyCredentials` automatically falls back to the simplified `tokenType=accesstoken` approach: the raw OAuth access token is sent as the `blob` with an empty `clientKey`. This token expires after ~60 minutes and the speaker cannot self-refresh, so periodic re-priming is required in that case.

+# Connecting Music Services (Spotify & Amazon Music)
+
+This guide explains how to link your Spotify or Amazon Music account to AfterTouch so your speakers can stream music from those services.
+
+---
+
+## How it works
+
+Connecting a music service happens in three separate steps, each done once:
+
+1. **Register a developer app** with Spotify or Amazon (one-time setup by the person running AfterTouch).
+2. **Authorize your personal account** so AfterTouch can access your music library.
+3. **Prime your speaker** so the speaker itself learns about the source.
+
+Each step is described below. If someone else is hosting AfterTouch for you, step 1 may already be done — ask them.
+
+---
+
+## Who registers the developer app?
+
+The developer app is what allows AfterTouch to talk to Spotify's or Amazon's servers on behalf of users. It requires registering an account on a developer portal.
+
+**If you run AfterTouch for yourself only:** You register one app and use it yourself.
+
+**If you run AfterTouch for a group** (e.g., your household): You register one app, configure it in AfterTouch, and everyone who uses your AfterTouch instance shares it. They never see your app credentials — those stay on your server. However, they do need to trust you, since their music account tokens are stored by your AfterTouch installation.
+
+**If you don't trust the AfterTouch operator:** Run your own AfterTouch instance and register your own app. That way everything stays under your control.
+
+---
+
+## Spotify
+
+### Step 1: Register a Spotify developer app
+
+1. Go to [developer.spotify.com/dashboard](https://developer.spotify.com/dashboard) and log in with your Spotify account.
+2. Click **Create app**.
+3. Give it any name and description (e.g., "My AfterTouch").
+4. Under **Redirect URIs**, add:
+   ```
+   http://<your-aftertouch-ip>:8000/mgmt/spotify/callback
+   ```
+   Replace `<your-aftertouch-ip>:8000` with the address of your AfterTouch server.
+5. Save the app.
+6. Open the app's settings and note down the **Client ID** and **Client Secret**.
+
+### Step 2: Enter credentials in AfterTouch
+
+1. Open the AfterTouch web interface and go to the **Settings** tab.
+2. Scroll to **Spotify Integration**.
+3. Enter your **Client ID**, **Client Secret**, and the **Redirect URI** you registered above.
+4. Click **Save Settings**.
+
+The status should change to **Active**.
+
+### Step 3: Authorize your Spotify account
+
+1. Go to the **Local Account** tab (tab 7).
+2. Click **Connect Spotify to this Account**.
+3. A Spotify login window opens. Log in and grant permission.
+4. When the window closes, your account is linked. You should see your Spotify username appear.
+
+### Step 4: Prime your speaker
+
+After authorizing, each speaker needs to be told about the Spotify source.
+
+1. Go to the **Devices** tab (tab 2).
+2. Find your speaker and click **Prime Spotify**.
+3. The speaker will now show Spotify as an available source.
+
+Repeat step 4 for each speaker.
+
+---
+
+## Amazon Music
+
+> **Current status: account linking works, streaming does not.**
+>
+> The OAuth flow and token storage are fully functional. However, the speaker's `AmazonClient` contacts `music-api.amazon.com` directly with the access token and receives a 401. Amazon Music's streaming API requires scopes that are only available to registered Amazon Music partners — a standard Login with Amazon app does not qualify. The infrastructure is in place and will work if those scopes ever become available, but following these steps will not result in working Amazon Music playback today.
+
+### Step 1: Register an Amazon developer app (LWA)
+
+1. Go to [developer.amazon.com/loginwithamazon/console/site/lwa/overview.html](https://developer.amazon.com/loginwithamazon/console/site/lwa/overview.html) and log in with your Amazon account.
+2. Click **Create a New Security Profile**.
+3. Give it any name and description (e.g., "My AfterTouch").
+4. In the security profile's **Web Settings**, add under **Allowed Return URLs**:
+   ```
+   http://<your-aftertouch-ip>:8000/mgmt/amazon/callback
+   ```
+   Replace `<your-aftertouch-ip>:8000` with the address of your AfterTouch server.
+5. Save and note down the **Client ID** and **Client Secret**.
+
+### Step 2: Enter credentials in AfterTouch
+
+1. Open the AfterTouch web interface and go to the **Settings** tab.
+2. Scroll to **Amazon Music Integration**.
+3. Enter your **Client ID**, **Client Secret**, and the **Redirect URI** you registered above.
+4. Click **Save Settings**.
+
+The status should change to **Active**.
+
+### Step 3: Authorize your Amazon account
+
+1. Go to the **Local Account** tab (tab 7).
+2. Click **Connect Amazon Music to this Account**.
+3. An Amazon login window opens. Log in and grant permission.
+4. When the window closes, your account is linked.
+
+### Step 4: Prime your speaker
+
+1. Go to the **Devices** tab (tab 2).
+2. Find your speaker and click **Prime Amazon**.
+3. The speaker will now show Amazon Music as an available source.
+
+Repeat step 4 for each speaker.
+
+---
+
+## Troubleshooting
+
+**"Failed to initialize" when clicking Connect:**
+The app credentials in Settings are missing or incorrect. Double-check the Client ID, Client Secret, and Redirect URI. The Redirect URI in AfterTouch must exactly match the one registered in the developer portal.
+
+**The login window opens but redirects to an error page:**
+The Redirect URI registered with Spotify/Amazon does not match what AfterTouch is sending. Make sure the address (including the port) is identical in both places.
+
+**The speaker doesn't show the new source after priming:**
+Try rebooting the speaker. It may take a minute to update its source list after priming.
+
+**The login window doesn't open (popup blocked):**
+Allow popups from the AfterTouch address in your browser settings, then try again. Alternatively, the status message will show a direct link you can click.

+# Self-Hosting AfterTouch
+
+This guide walks you through running AfterTouch on your own computer or server. No programming knowledge required.
+
+---
+
+## What is self-hosting?
+
+AfterTouch is software that runs on a computer in your home and takes over the role of Bose's cloud servers. Your speakers talk to it instead of Bose.
+
+For this to work, the computer running AfterTouch must be:
+
+- **Always on** (or at least on whenever you want to use your speakers)
+- **On the same local network** as your speakers
+- **Reachable by a stable IP address** (see [Stable IP Address](#stable-ip-address) below)
+
+Good choices: a Raspberry Pi, a NAS (like Synology or QNAP), an always-on PC or Mac, or a small server. A laptop that you close and put away is not ideal.
+
+---
+
+## Step 1: Get the software
+
+Go to the [AfterTouch releases page](https://github.com/gesellix/Bose-SoundTouch/releases) and download the latest release for your operating system:
+
+| Your system           | File to download                         |
+|-----------------------|------------------------------------------|
+| Raspberry Pi (64-bit) | `soundtouch-service_linux_arm64.tar.gz`  |
+| Raspberry Pi (32-bit) | `soundtouch-service_linux_arm.tar.gz`    |
+| Linux (64-bit PC)     | `soundtouch-service_linux_amd64.tar.gz`  |
+| macOS (Apple Silicon) | `soundtouch-service_darwin_arm64.tar.gz` |
+| macOS (Intel)         | `soundtouch-service_darwin_amd64.tar.gz` |
+| Windows               | `soundtouch-service_windows_amd64.zip`   |
+
+Extract the archive. You will find a single file called `soundtouch-service` (or `soundtouch-service.exe` on Windows).
+
+### Alternative: Docker
+
+If you already use Docker, you can run AfterTouch as a container instead. See the [Deployment Guide](DEPLOYMENT.md) for Docker instructions.
+
+---
+
+## Step 2: Run it
+
+Open a terminal (or Command Prompt on Windows), navigate to the folder where you extracted the file, and run:
+
+```
+./soundtouch-service
+```
+
+On Windows:
+```
+soundtouch-service.exe
+```
+
+You should see log output like:
+```
+Starting AfterTouch service on :8000
+```
+
+AfterTouch is now running on port 8000.
+
+---
+
+## Step 3: Open the web interface
+
+In a web browser on any device on your network, go to:
+
+```
+http://<your-server-ip>:8000
+```
+
+Replace `<your-server-ip>` with the actual IP address of the computer running AfterTouch. For example: `http://192.168.1.100:8000`.
+
+If you are on the same computer that is running AfterTouch, you can use `http://localhost:8000`.
+
+You should see the AfterTouch web interface with tabs: Overview, Settings, Devices, and so on.
+
+---
+
+## Step 4: Configure the server URL
+
+This is the most important setting. Go to the **Settings** tab and set the **Target Domain** to the full address of your AfterTouch server — the same address you used to open the web interface:
+
+```
+http://192.168.1.100:8000
+```
+
+Use the IP address of your server, **not** `localhost`. Your speakers need to reach this address over the network, and they cannot resolve `localhost`.
+
+Click **Save Settings**.
+
+---
+
+## Step 5: Proceed with migration
+
+You are now ready to migrate your speakers. Follow the main [Migration Guide](MIGRATION-GUIDE.md) for the remaining steps (discovering devices, syncing data, and redirecting your speakers to AfterTouch).
+
+---
+
+## Keeping AfterTouch running
+
+By default, AfterTouch stops when you close the terminal. To keep it running permanently:
+
+**Raspberry Pi / Linux:** See the [Raspberry Pi Guide](RASPBERRY-PI.md) for instructions on running AfterTouch as a background service using `systemd`.
+
+**NAS devices:** Most NAS systems support Docker. Use the Docker instructions in the [Deployment Guide](DEPLOYMENT.md).
+
+**macOS:** You can use `launchd` to run AfterTouch at login. Creating a `launchd` plist is beyond this guide, but the [Deployment Guide](DEPLOYMENT.md) has a systemd example you can adapt.
+
+**Windows:** You can use Task Scheduler to run AfterTouch at startup.
+
+---
+
+## Stable IP address
+
+AfterTouch must always be reachable at the same address, because your speakers will be configured to point to it. If the IP changes, your speakers will stop working until you reconfigure them.
+
+The easiest solution is to assign a **static (fixed) IP address** to the computer running AfterTouch in your router's settings. Look for "DHCP reservation" or "static IP" in your router's administration interface, and bind the server's MAC address to a fixed IP.
+
+---
+
+## Security note
+
+AfterTouch's web interface and management API have no login by default. On a typical home network this is fine, since only devices on your local network can reach it.
+
+If you want to restrict access — for example, on a shared network — start the service with a username and password:
+
+```
+./soundtouch-service --mgmt-username admin --mgmt-password yourpassword
+```
+
+This protects the Settings tab (where your Spotify and Amazon credentials are stored) from being read or changed by others on the network.

 - https://www.radio-browser.info is a community driven radio station database.
 - It provides an API to access the data and allows users to submit new stations or update existing ones.
+- RadioBrowser provides a native SoundTouch-compatible API at `https://all.api.radio-browser.info/soundtouch`.
+
+### Architecture
+
+This service registers RadioBrowser in its BMX service registry (provider ID 39) pointing to RadioBrowser's SoundTouch API. The device discovers it from there and communicates directly with RadioBrowser for browsing and playback — the local service does not proxy streams.
+
+The source is registered with type `RADIO_BROWSER` in the Marge sources list. The RadioBrowser provider ID (39) in the source entry identifies it as RadioBrowser within the BMX layer.
+
+The device's own `Sources.xml` (`/mnt/nv/BoseApp-Persistence/1/Sources.xml`) must contain a `RADIO_BROWSER` entry for playback to work:
+
+```xml
+<source secret="" secretType="">
+    <sourceKey type="RADIO_BROWSER" account="" />
+</source>
+```
+
+**A device reboot is required after adding this entry.** The firmware only registers `RADIO_BROWSER` as a selectable source type during the boot-time `Sources.xml` load. The Marge runtime sync stores the source in the registry but does not complete the activation — without a reboot, selecting a `RADIO_BROWSER` station results in `INVALID_SOURCE`.
+
+A reboot achieves two things in sequence:
+
+1. The speaker fetches all sources from the soundtouch-service via a `/full` request, which updates the device-local `Sources.xml`.
+2. The firmware initialises and registers the `RADIO_BROWSER` source type from that updated file.
+
+The `INVALID_SOURCE_TYPE` message from the Bluetooth daemon visible in device logs (e.g. during `GET /serviceAvailability`) is informational noise and does not affect playback.
+
+### Triggering a sources refresh without rebooting
+
+Step 1 above (the `/full` fetch that updates `Sources.xml`) can be triggered independently by posting a `sourcesUpdated` notification directly to the speaker. This is useful for verifying that the soundtouch-service serves the correct sources list before committing to a full reboot:
+
+```bash
+curl -v -X POST http://<speaker-ip>:8090/notification \
+     -H "Content-Type: application/xml" \
+     -d '<updates deviceID="<deviceID>"><sourcesUpdated/></updates>'
+```
+
+Replace `<speaker-ip>` with your speaker's IP address and `<deviceID>` with its device ID (visible in `/info`). After this call the speaker re-fetches its sources from the service. Step 2 (source-type registration) still requires a reboot.

+# 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>
+```
