docs(migration): add CLI-driven factory-reset alternative

The web-UI wizard is in-place migration: it preserves the speaker's existing pairing and synced data. The CLI sequence is a different shape — full factory-reset → wifi-push → pair against AfterTouch from scratch — and it's the right tool when you want a clean, scriptable, reproducible setup (automation, batched onboarding, or just starting from a reset speaker). Documents the full 6-step CLI flow (plan / factory-reset / wait-ap / wifi-push / wait-online / setup pair --mode=full), the verification checks, and a side-by-side comparison so users can pick the right path. Placed after "Repeat for each speaker" so the wizard remains the recommended default for one-off migrations. The flow assumes #195 and #269 are fixed in v0.80.2 — without the AUX/sources filter, the CLI factory-reset path produces a speaker where AUX won't dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
fix(cli): retry wifi-push once when the speaker's first ACK times out

+Bose is shutting down SoundTouch cloud services on **May 6, 2026**. After that, music service browsing, preset sync, and the official SoundTouch app stop working. This toolkit lets you keep your speakers fully functional.

-## Quick Start
+See the [Survival Guide](https://gesellix.github.io/Bose-SoundTouch/guides/SURVIVAL-GUIDE.html) for the full picture.

-### Installation
+---
+
+## Tools
+
+### soundtouch-service — AfterTouch
+
+A local server that replaces the Bose cloud ("AfterTouch"). Once your speaker is redirected to it, you have full control without any Bose cloud dependency. The built-in web UI at `http://localhost:8000` handles all setup — no config files needed to get started.
+
+If you want to run a server for this - no problem. The service is small enough to run on the SoundTouch itself. See the [On-Device Installer](./scripts/on-device-install/README.md) for instructions.
+
+**Two scenarios:**
+
+**Before shutdown — migrate your existing setup**
+While the Bose cloud is still running, use `soundtouch-backup` to save your account data. The local service web UI then helps with the migration so your speaker keeps its presets and credentials.
+
+**After shutdown or factory reset — start fresh**
+Create a local account, configure your speakers, and start using them immediately. No Bose infrastructure required.
+
+**Redirecting your speaker**
+
+The service needs a stable address on your local network (e.g. `soundtouch.fritz.box` or `soundtouch.local`). The speaker must then be redirected to resolve the Bose cloud hostnames to that address. Two supported methods:
+
+| Method       | How it works                        | Notes                                                        |
+|--------------|-------------------------------------|--------------------------------------------------------------|
+| XML redirect | Upload a config XML via the Web API | Surgical; covers only registered endpoints; best for testing |
+| DNS/DHCP     | Serve custom DNS on your network    | Covers all devices at once; requires port 53 and TLS         |
+
+The web UI walks you through each method. DNS redirect requires HTTPS — the service manages its own CA certificate and the web UI guides you through trusting it on each speaker.
+
+> **Note:** A hosts-file method (direct SSH edits to `/etc/hosts`) also exists in the codebase but is deprecated and not exposed in the web UI.
+
+**Enabling SSH via USB stick**
+
+Some setup steps require SSH access to the speaker. Enable it once per device: create a file named `remote_services` on a FAT-formatted USB drive (the drive may need its bootable flag set — see [SoundCork issue #172](https://github.com/deborahgu/soundcork/issues/172)), and insert it while the speaker is powered on. After reboot, root SSH is available with no password.
+
+See [Device Initial Setup](https://gesellix.github.io/Bose-SoundTouch/guides/DEVICE-INITIAL-SETUP.html) and [Migration Guide](https://gesellix.github.io/Bose-SoundTouch/guides/MIGRATION-GUIDE.html) for step-by-step instructions.
+
+---
+
+### soundtouch-backup
+
+Backs up your Bose cloud account (presets, paired devices, music sources) and each speaker's local state before the shutdown. Run `soundtouch-backup all` to capture everything in one step; it authenticates with the Bose cloud, then polls each paired speaker over the local network.
+
+See the [soundtouch-backup README](cmd/soundtouch-backup/README.md) for usage.
+
+---
+
+### soundtouch-cli
+
+Command-line control of any SoundTouch device: play/pause/volume, presets, source selection, multiroom zones, device discovery, and more. Works entirely over the local network — no cloud dependency. Well-suited for scripting and home automation.
+
+See the [CLI Reference](https://gesellix.github.io/Bose-SoundTouch/guides/CLI-REFERENCE.html) for full usage.
+
+---
+
+### soundtouch-web
+
+A standalone web UI for device control — play, pause, volume, preset selection, real-time status — served from a local Go binary. Complements `soundtouch-service` when you want a dedicated device-control interface separate from the setup/admin UI.
+
+See the [soundtouch-web README](cmd/soundtouch-web/README.md) for usage.
+
+---
+
+### Go library
+
+`pkg/client` provides a Go API for all SoundTouch device endpoints: media control, volume, presets, sources, zones, real-time WebSocket events, and device discovery. Use it to build your own integrations.

-## SoundTouch End of Life Notice
-
-**Important:** Bose has announced that [SoundTouch cloud support will end on May 6, 2026](https://www.bose.com/soundtouch-end-of-life).
-
-**What will continue to work:**
- ✅ Local API control (this library's primary functionality)
- ✅ Bluetooth, AirPlay, Spotify Connect, and AUX streaming
- ✅ Remote control features (Play, Pause, Skip, Volume)
- ✅ Multiroom grouping
-
-**What will stop working:**
- ❌ Cloud-based preset sync between devices and SoundTouch app
- ❌ Browsing music services directly from the SoundTouch app
- ❌ Cloud-based features and updates
-
-**What continues to work:**
- ✅ Local preset management via this API client (store, select, remove)
- ✅ Direct content playback (stations, playlists, etc.)
-
-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.
-
-**Community Alternatives**: See the [Related Projects](#related-projects) section below for additional tools like SoundCork that provide cloud service alternatives and the SoundTouch Plus project that offers comprehensive Home Assistant integration.

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

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

+
+Endpoints that return HTTP 4xx (not supported on the device model) are silently skipped.
+
+**What gets fetched via SSH** (`--ssh`)
+
+SSH connects as `root@<host>:22` with an empty password, which is the default for SoundTouch firmware.
+
+Individual files:

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

+# 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.

+*   **Mapped Preset `buttonNumber`**: Correctly mapped the internal `ServicePreset.ID` or `ButtonNumber` to the `buttonNumber` XML attribute in the `/full` response and ensured it is persisted in the local datastore.
+*   **High-Fidelity Device Metadata**: Improved the datastore to correctly extract, persist, and report detailed device `<components>` (e.g., `LIGHTSWITCH`, `SMSC`) and their firmware versions from upstream responses.
+*   **Standardized Preferred Language**: Updated the default `preferredLanguage` to `de` in the `/full` response and added synchronization to persist it from upstream responses.
+*   **Persisted Provider Settings**: Added support for persisting and echoing back `providerSettings` (e.g., `STREAMING_QUALITY`, `ELIGIBLE_FOR_TRIAL`) from the `/full` response.
 *   **Populated `contentItemType`**: The `contentItemType` (e.g., `tracklisturl`) is now correctly synchronized from upstream, persisted in the local datastore, and returned in the `/full` response for both presets and recents.
 *   **Standardized Credential Types**: Adjusted the logic for Spotify to use the correct `token_version_3` type when a token is present in the `/full` response, improving parity with the upstream service. The service now respects existing `credential_type` values from `Sources.xml` (e.g., `token_version_3` for Spotify) while providing sensible defaults for new or incomplete sources.
+*   **Structured Sources (Sources.xml)**: Refactored `Sources.xml` to use an attribute-based structure (`sourceid`, `source`, `status`, `sourceAccount`, etc.) matching the real device's output. Removed redundant nested tags like `<sourcename>`, `<username>`, and `<name>`.
+*   **Nested Recents (Recents.xml)**: Implemented a nested `<contentItem>` structure within `<recent>` entries in `Recents.xml`, maintaining exact parity with the device's persistence format while supporting legacy flat formats for backward compatibility.
 *   **Inconsistent `serialNumber` Casing**: Fixed the casing mismatch in the `/full` response where the upstream uses camelCase `<serialNumber>` in the top-level `<device>` and lowercase `<serialnumber>` in the nested `<attachedProduct>`. Local responses now correctly mirror this inconsistency.
+*   **Attribute-level Parity**:
+    *   Ensured `sourceAccount=""` is preserved in XML even when empty, matching device behavior for sources like TUNEIN.

 *   **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.

 #### 1. BMX / TuneIn Playback Parity (Medium)
 Current mismatches in `/bmx/tunein/v1/playback/station/...` show differences in reporting URLs and missing links:
-*   **Mismatched Parameters**: Local reporting URLs use `listen_id=3432432423`, while upstream uses a different session-based ID.

 *   **Missing Links**: Some upstream responses include additional `_links` or metadata that are currently omitted in local responses.
 *   **Action**: Improve the `HandleTuneInPlayback` logic to better mirror the upstream response structure and parameter generation.

-#### 2. Presets and Recents Parity (Medium)
-Further align the standalone `GET /presets` and `GET /recents` endpoints with the refined structural improvements introduced for the `/full` account response:
-*   **Source Nesting**: Ensure the standalone responses also use the specialized nested `<source>` structure instead of mixed attributes when appropriate.
-*   **Field Completeness**: Verify all metadata fields (e.g., `<contentItemType>`, `<lastplayedat>`) are consistently populated across all access paths.
-*   **Action**: Evaluate if the specialized `FullResponsePreset` and `FullResponseRecent` models should be shared or mirrored in the standalone handlers.
+#### 2. `/full` Account Response Data Gaps (Medium)
+While structural parity for the `/full` response is high, several value-level gaps remain as shown in `diff14`:
+*   **Timestamp Formats**: Upstream uses ISO-8601 with milliseconds (e.g., `2024-06-23T07:40:36.000+00:00`), whereas some local fields still use Unix epoch integers (e.g., `1234567890`).
+*   **Provider Settings**: The `providerSettings` block in the local response currently lacks crucial values like `keyName`, `providerId`, and `boseId` (appearing as empty tags).
+*   **Component Metadata**: Local component types are sometimes empty (`type=""`) compared to upstream values like `LIGHTSWITCH` or `SMSC`.
+*   **Source/Preset Identifiers**: Local IDs (e.g., `100004`) differ from upstream IDs (e.g., `1234567`), though this may be expected due to different account/device environments.
+*   **Action**: Update the mapping logic in `marge.go` and `setup.go` to ensure all fields in the `/full` response are correctly populated with high-fidelity values and standard ISO-8601 timestamps.

-    *   Missing/empty `<username>` at the `<preset>` level.
-*   **Values**:

+    *   **Nested Source Association**: Improved the matching logic in `mapRecentsToFullResponse` to correctly link recents to their specific `ConfiguredSource` (e.g., by matching `sourceid` attribute).
+    *   **XML Tag Formatting**: Standardized self-closing tags and element formatting to match upstream's multi-line or empty-element formatting in various contexts.

+# Parity Analysis: Bose-SoundTouch (Go) vs. OpenCloudTouch (Python)
+
+This document provides a comparative analysis of the current Go implementation and the `scheilch/opencloudtouch` project, identifying functional gaps and potential improvements.
+
+## 1. Core Architecture and Language
+- **Bose-SoundTouch (Go)**: A high-performance, strongly typed backend with a CLI and background service. Focuses on full API coverage, parity testing, and robust hardware control (DSP, zones).
+- **OpenCloudTouch (OCT)**: A modern full-stack application (FastAPI + React/TypeScript). Prioritizes user experience with a web-based setup wizard and a clean abstraction for internet radio.
+
+## 2. Functional Comparison
+
+| Feature                 | Bose-SoundTouch (Go)                                       | OpenCloudTouch (Python)                                                 |
+|:------------------------|:-----------------------------------------------------------|:------------------------------------------------------------------------|
+| **Setup Experience**    | CLI-driven or manual API calls for migration (SSH, XML).   | Web-based **Setup Wizard** guides through SSH, backup, and redirection. |
+| **Radio Support**       | Static integration of **RadioBrowser** and TuneIn.         | Dynamic **RadioBrowserAdapter** with automatic **API Failover**.        |
+| **Commercial Services** | Deep integration (Spotify priming, Pandora, Deezer, etc.). | Basic support, focus is on local content and radio.                     |
+| **Hardware Control**    | Extensive (Bass, Treble, Soundbar levels, Clock display).  | Basic playback and zone controls.                                       |
+| **Cloud Emulation**     | High-fidelity parity (mirroring, discrepancy logging).     | Functional emulation for local preset/recent persistence.               |
+| **Notifications**       | Built-in **TTS** and custom URL audio alerts.              | Not a primary focus.                                                    |
+
+## 3. Key Strengths of OpenCloudTouch
+- **Guided Onboarding**: The setup wizard reduces the entry barrier for non-technical users significantly.
+- **Resilient Radio**: The API failover for RadioBrowser ensures continuous service even if specific community-hosted API instances go offline.
+- **Modern API Stack**: Uses OpenAPI and generated TypeScript types for a seamless frontend integration.
+- **Provider Abstraction**: A cleaner internal separation between the "Bose World" (XML/BMX) and external content providers (RadioBrowser).
+
+## 4. Suggested Improvements for Bose-SoundTouch
+
+### A. Web-based Setup Wizard (High Priority)
+- Implement a state-driven wizard in the `soundtouch-service` to handle:
+  - SSH activation (checking `/remote_services` via USB).
+  - Automated backup of speaker configuration.
+  - Verification of DNS/Hosts redirection.
+- Expose this via a simple embedded Web UI (using Go's `embed` package).
+
+### B. RadioBrowser Failover (Medium Priority)
+- Adapt the failover logic from OCT:
+  - Periodically refresh the list of available RadioBrowser API servers.
+  - Implement a retry mechanism that switches servers on 5xx errors or timeouts.
+
+### C. External Service Abstraction (Medium Priority)
+- Refactor the hardcoded BMX logic into a more modular **Provider System** (see `EXTERNAL-SERVICES-ABSTRACTION.md`).
+- This will allow easier addition of new sources (e.g., local DLNA, generic M3U playlists) without touching the core BMX handlers.
+
+## 5. Summary
+While our Go project provides the most complete technical coverage of SoundTouch hardware and commercial services, OpenCloudTouch sets a higher standard for **user onboarding** and **service resilience** for community-driven content. Integrating a setup wizard and a more robust radio backend would make our project significantly more accessible and reliable.

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

+# 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.
+
+## Automated Setup
+
+The steps in this document are scripted for reproducibility:
+
+```bash
+scripts/android/setup-mitm-avd.sh   # one-time: create AVD, install cert & APK, save snapshot
+scripts/android/start-mitm-session.sh  # per-session: restore snapshot, refresh proxy, start frida-server
+```
+
+Read on for the full manual walkthrough and the rationale behind each step.
+
+> **Note:** The manual steps below use `/tmp/` for intermediate files and reflect the original approach. The automated scripts supersede them — use the scripts for day-to-day use and refer here only to understand how things work.
+
+---
+
+## 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)
+
+> **BLE limitation**: Android emulators do not expose Bluetooth hardware. The Bose app's default setup path (BLE Wi-Fi provisioning) therefore cannot be used to configure a factory-reset speaker from the emulator. Use **AP mode** instead: provision the speaker's Wi-Fi credentials via the Mac command line first (see [DEVICE-INITIAL-SETUP.md § 6](../guides/DEVICE-INITIAL-SETUP.md)), then the app can discover the already-networked speaker via mDNS/SSDP without BLE.
+
+> **Emulator ↔ local network**: The emulator routes all traffic through the Mac's active network interface. Once the speaker is on the same LAN as the Mac, the emulator can reach it at its normal LAN IP (e.g. `192.168.1.50`) — no extra routing is needed. Use `adb shell ping 192.168.1.50` to confirm reachability.
+
+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)
+# Use the native macOS app — Docker mitmproxy does not work (NAT blocks emulator traffic)
+mitmweb --listen-port 8080 --mode regular -w bose_traffic.mitm
+```
+
+Extract the CA certificate (without private key):
+
+```bash
+openssl x509 -in ~/.mitmproxy/mitmproxy-ca.pem -out ~/.mitmproxy/mitmproxy-ca-cert.pem
+
+# Verify it's the mitmproxy cert, not another cert:
+openssl x509 -in ~/.mitmproxy/mitmproxy-ca-cert.pem -noout -issuer
+# should show: issuer= /CN=mitmproxy/O=mitmproxy
+```
+
+---
+
+## 6. Install mitmproxy CA Certificate in Emulator
+
+```bash
+HASH=$(openssl x509 -inform PEM -subject_hash_old \
+  -in ~/.mitmproxy/mitmproxy-ca-cert.pem | head -1)
+
+adb -s emulator-5554 push ~/.mitmproxy/mitmproxy-ca-cert.pem /data/local/tmp/mitmproxy.pem
+
+adb -s emulator-5554 shell su 0 mkdir -p /data/misc/user/0/cacerts-added
+
+adb -s emulator-5554 shell su 0 \
+  cp /data/local/tmp/mitmproxy.pem /data/misc/user/0/cacerts-added/${HASH}.0
+
+adb -s emulator-5554 shell su 0 \
+  chmod 644 /data/misc/user/0/cacerts-added/${HASH}.0
+```
+
+---
+
+## 7. Set System Proxy in Emulator
+
+Find your Mac's local IP:
+
+```bash
+ipconfig getifaddr en0
+# e.g. 192.168.1.123
+```
+
+Set the proxy:
+
+```bash
+adb -s emulator-5554 shell settings put global http_proxy 192.168.1.123:8080
+```
+
+---
+
+## 8. Set Up Frida (via Python venv)
+
+```bash
+python3 -m venv /tmp/frida-venv
+/tmp/frida-venv/bin/pip install frida==17.9.1 frida-tools==14.8.1
+```
+
+Download the frida-server binary for ARM64 Android:
+
+```bash
+FRIDA_VERSION=17.9.1
+
+curl -L "https://github.com/frida/frida/releases/download/${FRIDA_VERSION}/frida-server-${FRIDA_VERSION}-android-arm64.xz" \
+  -o /tmp/frida-server.xz
+
+unxz /tmp/frida-server.xz
+mv /tmp/frida-server-${FRIDA_VERSION}-android-arm64 /tmp/frida-server
+```
+
+Push to emulator and start:
+
+```bash
+adb -s emulator-5554 push /tmp/frida-server /data/local/tmp/frida-server
+adb -s emulator-5554 shell su 0 chmod 755 /data/local/tmp/frida-server
+adb -s emulator-5554 shell su 0 /data/local/tmp/frida-server &
+```
+
+---
+
+## 9. Download SSL Bypass Scripts
+
+```bash
+BASE=https://raw.githubusercontent.com/httptoolkit/frida-interception-and-unpinning/main
+
+curl -L "${BASE}/config.js" -o /tmp/config.js
+curl -L "${BASE}/android/android-system-certificate-injection.js" \
+  -o /tmp/android-system-certificate-injection.js
+curl -L "${BASE}/android/android-proxy-override.js" \
+  -o /tmp/android-proxy-override.js
+curl -L "${BASE}/android/android-certificate-unpinning.js" \
+  -o /tmp/android-certificate-unpinning.js
+curl -L "${BASE}/android/android-certificate-unpinning-fallback.js" \
+  -o /tmp/android-certificate-unpinning-fallback.js
+```
+
+---
+
+## 10. Configure config.js
+
+Edit `/tmp/config.js` and set:
+
+```javascript
+const CERT_PEM = `<contents of ~/.mitmproxy/mitmproxy-ca-cert.pem>`;
+
+const PROXY_HOST = '192.168.1.123';  // your Mac IP
+const PROXY_PORT = 8080;
+```
+
+Insert the full PEM content (from `-----BEGIN CERTIFICATE-----` to `-----END CERTIFICATE-----`) between the backticks.
+
+Quick check that the right cert is in place:
+
+```bash
+# The issuer inside config.js should be mitmproxy, not SoundTouch
+grep -A3 "CERT_PEM" /tmp/config.js | head -5
+```
+
+---
+
+## 11. Start Interception
+
+Make sure mitmweb is running, then:
+
+```bash
+scripts/android/frida-venv/bin/frida \
+  -U \
+  -f com.bose.soundtouch \
+  -l scripts/android/frida/config.js \
+  -l scripts/android/frida/native-connect-hook.js \
+  -l scripts/android/frida/android/android-system-certificate-injection.js \
+  -l scripts/android/frida/android/android-proxy-override.js \
+  -l scripts/android/frida/android/android-certificate-unpinning.js \
+  -l scripts/android/frida/android/android-certificate-unpinning-fallback.js
+```
+
+> `native-connect-hook.js` is required — the Bose app uses native networking that bypasses Java proxy settings.
+
+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
+```
+
+---
+

+| frida and frida-server version mismatch | Versions must be identical                       | Pin both to same version (e.g. `17.9.1`)                                       |
+| `emulator: multiple AVDs` error         | Emulator already running                         | Kill first: `adb emu kill`, then restart with `-writable-system`               |
+
+---
+
+## 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
+```

+> **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

 To enable offline operation or use custom services like **SoundCork** or **ÜberBöse API**, SoundTouch devices must be redirected from Bose's official cloud endpoints to a local or custom server.

+# What a SoundTouch speaker does during factory reset
+
+Observed live on ST10 firmware `27.0.6.46330.5043500` (build `epdbuild.trunk.hepdswbld04.2022-08-04`) on 2026-05-12, by running `soundtouch-cli setup factory-reset` and tailing the speaker's `logread` over SSH. The trace is preserved at `_/logs/factory-reset.txt` for reference.
+
+## Sequence
+
+1. **Telnet receives `sys factorydefault`.** The diagnostic shell on port 17000 accepts the command and acknowledges. Some firmwares close the socket as part of the reboot — our CLI's `setup factory-reset` tolerates that as success.
+
+2. **Speaker DELETEs itself from its marge account.** Before wiping anything, the firmware does:
+   ```
+   [MargeStateAssociated] HandleRemoveDeviceRequest - Removing this device from the user's Marge account
+   [MargeClient]          RemoveDevice calling Marge Server with https://streaming.bose.com/streaming/account/{accountId}/device/{deviceId}
+   [MargeClient]          RemoveDeviceCB - Device removed from the user's Marge account
+   [MargeStateAssociated] HandleRemoveDeviceRequestSuccessCB, Marge returned: {"ok": true}
+   ```
+   AfterTouch already handles this — `HandleMargeRemoveDevice` (`pkg/service/handlers/handlers_marge.go:633`) routed via `r.Delete("/device/{device}", …)` in `cmd/soundtouch-service/main.go:955`. The handler calls `marge.RemoveDeviceFromAccount(s.ds, account, device)` and prunes the device from the datastore.
+
+3. **Speaker notifies its LAN peers.** Two HTTP POSTs to each known peer at `:8090/notification`:
+   ```
+   [NotificationSender] SendNotifyLisas_: URL: >>http://192.168.123.122:8090/notification<<, m_msgdata.size(58)
+   [SimpleURLFetcher]   multipart/form-data text/xml
+   ```
+   ~58 bytes of `multipart/form-data` carrying `text/xml`. "Lisas" is the firmware's internal term for LAN peers (devices on the same account on the same network segment). AfterTouch is **not** on this path — it's pure peer-to-peer over the LAN. Peers presumably refresh their account info as a result.
+
+4. **Local state teardown.** Bluetooth pairings cleared (`BTRemoteDeviceAccess::ClearPrevPairedList`), zone/group state torn down, all source proxies disconnected (`STSAccountProxy::Disconnect Requested` × many).
+
+5. **Persistence cleanup.** Logs, core dumps wiped (`FactoryDefault: Clearing the CoreDump and BoseLogs … rm -rf /mnt/nv/BoseLog/*`). Notably **NOT wiped**: `/mnt/nv/aftertouch.resolv.conf`, `/mnt/nv/rc.local`'s Aftertouch hook, and `/mnt/nv/BoseApp-Persistence/1/SystemConfigurationDB.xml`. The reset only touches log directories and account-specific persistence under the same `/mnt/nv/BoseApp-Persistence/1/` tree.
+
+6. **Reboot into setup mode.** Speaker drops Wi-Fi, comes back as its own AP `Bose SoundTouch XXXX` on 192.0.2.1.
+
+## Implications for migration ordering
+
+The DELETE in step 2 only reaches AfterTouch if the speaker's `margeURL` already points at AfterTouch *at the moment of reset*. A speaker still pointing at `streaming.bose.com` sends it into the void → AfterTouch keeps a stale `account/{id}/device/{id}` entry until someone manually prunes it.
+
+Therefore for a clean datastore lifecycle on an already-Bose-paired speaker:
+
+1. Migrate URLs first (`setup migrate --method=resolv` or `--method=telnet`).
+2. Reboot to apply.
+3. Factory reset.
+4. Re-provision.
+
+`soundtouch-cli setup plan --reset` currently runs factory-reset first (optimal for already-on-AfterTouch speakers); both `setup plan --reset` and `setup factory-reset` print a one-line note explaining the ordering tradeoff so users can pick the right sequence for their starting state.
+
+## Implications for AfterTouch behaviour
+
+- The DELETE handler is already correct; no changes needed.
+- AfterTouch is invisible to the LAN-peer notification step — that's just LAN HTTP between speakers.
+- If you build a "consolidate account" / "migrate fleet" feature later, the peer-notification channel is the propagation path the firmware uses internally; AfterTouch doesn't need to do anything analogous.
+- The persistence layer at `/mnt/nv/` is **factory-reset-resistant**. Our DNS-redirect migration (`setup migrate --method=resolv`) writes there specifically so AfterTouch routing survives a reset. This is intentional — the user can factory-reset a speaker freely without re-running migration.
+
+## Open questions
+
+- Are there other peer endpoints the firmware POSTs to besides `:8090/notification`? Worth checking on a 3-speaker LAN.
+- Does the `:8090/notification` payload format match the format used for play-as-notification audio pushes, or is it a distinct message shape? The "size(58)" byte count is too small for an audio URL but big enough for an XML envelope with an event type.
+
+If you want either of these answered, capture two synchronised `logread -f` streams from two LAN speakers while one is being reset.

+# 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.

+# Experiment: Does bare `setMargeAccount` work outside the SETUP bracket?
+
+## Why we are doing this
+
+Our captured pairing flow (`docs/reference/DEVICE-PAIRING-FLOW.md`) shows the official Bose app always sends `setMargeAccount` *inside* a `SETUP_START` → `SETUP_ENTER` → `SETUP_LEAVE` state-machine bracket over WebSocket. The question this experiment answers:
+
+> If we open a WebSocket to a factory-reset speaker and send **only** `setMargeAccount` — no surrounding setupState messages — does the device honor it and write its persistence files (`SystemConfigurationDB.xml`, `Sources.xml`) cleanly?
+
+The answer determines the shape of `PairAccount`:
+
+- **If YES:** `PairAccount` becomes uniform: WebSocket-first, HTTP `/setMargeAccount` second, telnet `envswitch accountid set` third. One function, one ordering, all callers.
+- **If NO:** WebSocket pairing is only meaningful inside the full state machine. Factory-reset path uses the state machine; re-pair path keeps today's HTTP→telnet ordering.
+
+## Preconditions
+
+- A SoundTouch speaker that has been **factory-reset** and joined to the test Wi-Fi.
+- Speaker reachable on `:8090` (HTTP API) and `:8080` (WebSocket).
+- Speaker's runtime marge URL already points at AfterTouch (run the existing telnet URL rewrite first — otherwise the device's downstream POST will land on the dead Bose cloud and we will not be able to distinguish "WS message refused" from "downstream cloud failed").
+- A free 7-digit account ID — for example, generated via `setup.GenerateAccountID(nil)`.
+
+## Step 0 — Baseline
+
+```bash
+DEVICE=192.168.x.x
+curl -s http://$DEVICE:8090/info     | xmllint --format -
+curl -s http://$DEVICE:8090/sources  | xmllint --format -
+curl -s http://$DEVICE:8090/presets  | xmllint --format -
+```
+
+Record:
+
+- `<margeAccountUUID>` — expect empty on a factory-reset device.
+- `<margeURL>` — expect the AfterTouch URL (preflight already applied).
+- `<sources>` — expect a minimal list.
+- `<presets>` — expect `<presets/>`.
+
+## Step 1 — Send bare `setMargeAccount` over WebSocket
+
+Build the CLI once:
+
+```bash
+make build
+```
+
+Then run the bare path against the speaker:
+
+```bash
+DEVICE=192.168.x.x
+./build/soundtouch-cli setup pair --host=$DEVICE --account=1234567 --mode=bare
+```
+
+What it does:
+
+1. Reads `/info` to discover `deviceID`, logs the pre-state.
+2. Opens a WebSocket to `$DEVICE:8080` with the `gabbo` subprotocol.
+3. Sends exactly one frame — the `setMargeAccount` envelope — **without** any preceding `SETUP_START`/`SETUP_ENTER`.
+4. Reads frames for up to `--step-timeout=8s` (configurable), looking for an ack referencing our `requestID`.
+5. Closes the WebSocket, waits 2 s, re-reads `/info`, prints whether `margeAccountUUID` now equals our supplied ID.
+
+The exact frame sent (built by `setup.SetupSession.SetMargeAccount`):
+
+```xml
+<msg><header deviceID="DEVICE_ID" url="setMargeAccount" method="POST"><request requestID="1"/></header><body>
+  <PairDeviceWithAccount>
+    <accountId>1234567</accountId>
+    <userAuthToken>Bearer aftertouch</userAuthToken>
+  </PairDeviceWithAccount>
+</body></msg>
+```
+
+Outcomes the CLI will surface:
+
+- `Device accepted bare pairing.` (post-`/info` shows our ID) → **bare path works**.
+- `setMargeAccount: device rejected setMargeAccount: …` → device returned an `<error>` body → **bare path refused explicitly**.
+- `setMargeAccount: await ack for setMargeAccount: …` (timeout or EOF) → **bare path refused silently**.
+- `Device did NOT persist the pairing — bare path likely refused silently.` → ack received but persistence didn't follow.
+
+## Step 2 — Record outcome
+
+After step 1 (regardless of which branch happened):
+
+```bash
+sleep 2
+curl -s http://$DEVICE:8090/info | grep margeAccountUUID
+```
+
+| Observed result                                                              | Verdict                     |
+|------------------------------------------------------------------------------|-----------------------------|
+| `<margeAccountUUID>1234567</margeAccountUUID>` appears                       | **YES** — Option 1 wins     |
+| `<margeAccountUUID></margeAccountUUID>` still empty, no error frame received | Refused silently → **NO**   |
+| Error frame returned (e.g. `<error name="UNSUPPORTED_STATE"/>`)              | Refused explicitly → **NO** |
+| Device drops the WebSocket connection without replying                       | Refused → **NO**            |
+
+If verdict is YES, also verify the device wrote persistence cleanly. Reboot the device, then:
+
+```bash
+ssh root@$DEVICE 'cat /mnt/nv/BoseApp-Persistence/1/SystemConfigurationDB.xml'
+ssh root@$DEVICE 'cat /mnt/nv/BoseApp-Persistence/1/Sources.xml'
+curl -s http://$DEVICE:8090/info | grep margeAccountUUID
+```
+
+The UUID must still be present after reboot, and `SystemConfigurationDB.xml` must contain `<AccountUUID>1234567</AccountUUID>`. If it survives reboot, **YES** is confirmed.
+
+## Step 3 — Control: full state machine
+
+Factory-reset the same speaker again and run the full state machine — the same CLI, `--mode=full`:
+
+```bash
+./build/soundtouch-cli setup pair --host=$DEVICE --account=1234567 --mode=full
+```
+
+This drives `setup.Manager.ExecuteInitPlan` with `SkipURLRewrite=true`, which runs:
+
+```
+SETUP_START
+SETUP_IDENTIFY_DEVICE_ENTER
+language sysLanguage=2
+SETUP_ENTER
+SETUP_IDENTIFY_DEVICE_LEAVE
+setMargeAccount …
+SETUP_LEAVE
+pushCustomerSupportInfoToMarge
+```
+
+The CLI logs every step with status. Confirm `/info`, persistence, and reboot-survival checks pass. If the bare path failed but the full path succeeds, the SETUP bracket is load-bearing — a follow-up bisect (e.g. `SETUP_START + setMargeAccount + SETUP_LEAVE` only) tells us *which* surrounding messages the firmware actually requires.
+
+## Full reset-and-rebuild loop
+
+Once the bare/full question is decided, the loop for repeated experiments is:
+
+```bash
+# 0. Speaker is currently on home Wi-Fi at $DEVICE.
+#    Capture deviceID-suffix + current SSID first so wait-online and
+#    wifi-push have the right inputs.
+./build/soundtouch-cli setup inspect --host=$DEVICE
+./build/soundtouch-cli setup factory-reset --host=$DEVICE
+
+# 1. Manually switch this host to the speaker's AP (Bose SoundTouch XXXX).
+#    macOS: networksetup -setairportnetwork en0 "Bose SoundTouch XXXX"
+
+./build/soundtouch-cli setup wait-ap
+./build/soundtouch-cli setup wifi-push --ssid="$HOME_SSID" --pass="$HOME_PASS"
+
+# 2. Manually switch this host back to home Wi-Fi.
+
+./build/soundtouch-cli setup wait-online --match=DE4803          # deviceID suffix from /info before reset
+# (note the new IP from the "Speaker discovered" line)
+
+NEW_IP=192.168.x.y
+./build/soundtouch-cli setup migrate --host=$NEW_IP --service-url=http://aftertouch.local:8000   # default --method=telnet
+
+# Optional, if you want the DNS-redirect path instead of (or alongside) telnet envswitch:
+#   1. ./build/soundtouch-cli setup ssh-check --host=$NEW_IP            # USB-stick procedure if 22 is closed
+#   2. ./build/soundtouch-cli setup install-ca --host=$NEW_IP --service-url=http://aftertouch.local:8000
+#   3. ./build/soundtouch-cli setup migrate --host=$NEW_IP --service-url=http://aftertouch.local:8000 --method=resolv
+./build/soundtouch-cli setup pair --host=$NEW_IP --mode=bare   # or --mode=full
+```
+
+The two manual lines are user-side Wi-Fi switches that can't be automated portably. The `wait-ap` and `wait-online` subcommands poll for the corresponding network state, so timing them is hands-off.
+
+## Recording the result
+
+Append to this file under `## Results`:
+
+```
+- Date: YYYY-MM-DD
+- Firmware: 27.x.x
+- Model: ST10 / ST20 / ST30 / ST300
+- Bare setMargeAccount accepted: yes/no
+- Persistence written: yes/no
+- Survives reboot: yes/no
+- Notes: ...
+```
+
+One row per device tested. Once two devices on different firmware confirm the same verdict, we treat it as decided.
+
+## Results
+
+- Date: 2026-05-13
+- Firmware: 27.0.6.46330.5043500 (build epdbuild.trunk.hepdswbld04.2022-08-04T11:20:29)
+- Model: SoundTouch 10 (deviceID A81B6A536A98)
+- Bare setMargeAccount accepted: **yes** — pre-/info margeAccountUUID="" → post-/info margeAccountUUID="1111111"
+- Persistence written: **yes** — device materialized 14-entry Sources.xml on its own
+- Survives reboot: **yes** — `setup inspect` after `setup reboot` shows margeAccountUUID still 1111111
+- Notes: After bare pairing, the speaker did the full post-pairing handshake against AfterTouch (POST /streaming/support/power_on, GET /streaming/sourceproviders, GET /streaming/account/{id}/full, group/, provider_settings). No SETUP_START/SETUP_ENTER/SETUP_LEAVE was ever sent. Verdict: bare path is functionally equivalent to the full state machine on this firmware.
+
+### Implication for the codebase
+
+- `pkg/service/setup/setup_session.go` keeps the full state machine for completeness, but
+- `pkg/service/setup/init_plan.go`'s default could be simplified to "send setMargeAccount only" once we have one more confirming run on a different model.
+- The OCT issue-167 SSH-XML seeding workaround is **not required**.
+
+### Appendix — SystemConfigurationDB.xml comparison
+
+Post-experiment we compared the device-written `/mnt/nv/BoseApp-Persistence/1/SystemConfigurationDB.xml` from the bare-paired speaker against two SSH backups taken from speakers originally paired by the official Bose app (account 3230304, devices `A_Sound_Machine` and `Sound_Machinechen`). The diff is much smaller than expected — only two fields differ, and neither is set by the pairing protocol itself:
+
+| Field                    | Bare-paired (1111111)                      | Real-Bose-paired (3230304) | Set by                                                                                                    |
+|--------------------------|--------------------------------------------|----------------------------|-----------------------------------------------------------------------------------------------------------|
+| `DeviceName`             | `Bose SoundTouch 536A98` (factory default) | `Sound Machinechen`        | `name` WS message — only sent in `--mode=full`                                                            |
+| `AccountAssociatedEMail` | empty                                      | **empty**                  | Never populated, even by real Bose                                                                        |
+| `AccountUUID`            | `1111111`                                  | `3230304`                  | `setMargeAccount` — both paths set it                                                                     |
+| `Locale`                 | empty                                      | **empty**                  | Never populated, even by real Bose                                                                        |
+| `acctMode`               | `global`                                   | `global`                   | Firmware-default; no protocol path observed to change it                                                  |
+| `isMultiDeviceAccount`   | `false`                                    | `true`                     | Derived from the cloud's `/streaming/account/{id}/full` response — count of `<devices>` > 1 flips it true |
+| `margeAuthServerToken`   | empty                                      | **empty**                  | Never populated, even by real Bose                                                                        |
+| `Password`               | (encrypted blob)                           | (encrypted blob)           | Device-local key; expected to differ                                                                      |
+
+Three of the seven informational fields are empty even after a real-Bose pairing — the firmware simply doesn't populate `AccountAssociatedEMail`, `Locale`, or `margeAuthServerToken` from the pairing flow. So bare pairing isn't missing any field that real pairing fills.
+
+The two genuinely different fields:
+
+- **`DeviceName`** — pure UX. Settable any time post-pair via `name` POST (`soundtouch-cli name set --value=…`) or by sending the `name` WS message during `--mode=full` pairing.
+- **`isMultiDeviceAccount`** — not a pairing concern. It's derived from the account's device count on AfterTouch's side; flips to `true` automatically the next time the speaker refreshes account state if a second speaker has been paired to the same account.
+
+So the experiment's YES verdict stands unqualified: bare `setMargeAccount` produces a `SystemConfigurationDB.xml` functionally equivalent to one written by the official pairing flow.

+## Connecting to the shell
+
+### From an already-on-network device
+
+The shell binds to TCP port 17000 on every device family observed (ST 10/20/300, Wave III/IV, ST 520, SA-5 — see §"Firmware era notes" for caveats). No authentication.
+
+```bash
+# A no-op probe just to verify reach.
+echo '' | nc -w 2 <device-ip> 17000
+
+# Or interactively — works the same.
+telnet <device-ip> 17000
+```
+
+The `bose` script (S4) goes one level lower and writes commands directly to a `/dev/tcp/<ip>/17000` redirection target instead of using `nc`. That's the same wire protocol with no library between.
+
+### From a factory-fresh / WiFi-less device
+
+Per S2/S3 — newer firmware may have closed this on some models:
+
+1. **Enter setup mode.** Press and hold key **2** + **volume down** for 5 seconds until the WiFi LED turns amber.
+2. **Connect your laptop to the speaker's open access point.** The speaker becomes its own AP.
+3. **Telnet to `192.0.2.1` on port 17000.**
+
+Once you've added a WiFi profile (see `network wifi profiles add` below) the speaker reboots into station mode and the AP goes away.
+
+### Hardware key combinations on the device itself

+
+**Example session — adding a network from setup mode (S3):**
+
+```
+network wifi profiles add foobarHub wpa_or_wpa2 topsecret
+```
+
+The speaker stores the profile, drops the setup AP, and reboots into station mode.

+
+## The `key` family — front-panel button emulation
+
+Each `key …` command emulates a press of a physical button on the speaker
+or remote. Confirmed working on ST 10 / FW `27.0.6.46330.5043500` (S5);
+also visible on the ST 20/300/Wave captures in #221. Different from the
+`sys presetkey N p` form (S4) — the `key prefix_N` shape on FW 27 is what
+the device's own remote sends.
+
+| Command                         | Effect                                                                                | Source |
+|---------------------------------|---------------------------------------------------------------------------------------|--------|
+| `key prefix_1` … `key prefix_6` | Triggers preset 1–6 (same as a remote preset press).                                  | S5     |
+| `key play`                      | Begin / resume playback.                                                              | S5     |
+| `key pause`                     | Pause playback.                                                                       | S5     |
+| `key stop`                      | Stop playback (does **not** terminate the underlying stream).                         | S5     |
+| `key prev`                      | Restart current song / previous track.                                                | S5     |
+| `key next`                      | Next track.                                                                           | S5     |
+| `key aux`                       | Toggle Bluetooth / AUX input.                                                         | S5     |
+| `key power`                     | Echoes "OK" but no observable effect on FW 27.x — possibly handled at a higher layer. | S5     |
+
+The S4 `bose` script's `sys presetkey N p` form still works, but `key prefix_N` is shorter and matches what the remote already does on FW 27.x.

+## The `sys` family — system control & service URLs
+
+The `sys` family is the one our migration uses (see §"What we use during migration"). Two distinct sub-syntaxes coexist:
+
+- **Single-token verbs:** `sys reboot`, `sys volume`, `sys power`, etc.
+- **`sys configuration <key> <value>` setters** that modify persisted runtime configuration. Used for the four service URLs (margeServerUrl, statsServerUrl, swUpdateUrl, bmxRegistryUrl).

+
+## The `envswitch` family — parallel persistence layer
+
+`envswitch` writes to a separate, lower-level persistence store that **wins on next reboot** if the corresponding `sys configuration` value differs. So our migration writes both — see TELNET-MIGRATION-METHOD.md §2.1.

+|---------------------------------------------------|-----------------------------------------------------------------------------------------------|---------|
+| `envswitch boseurls set <margeUrl> <swUpdateUrl>` | Persist the marge and update URLs. **Two arguments**, in that order.                          | S6      |
+| `envswitch accountid set <numeric-id>`            | Equivalent to the HTTP `/setMargeAccount` POST. Used as fallback in our `PairAccount` helper. | S6      |

+
+## The `getpdo` family — read persisted configuration
+
+`getpdo <selector>` prints the contents of a persisted-data-object. We use it as the verification step after writing URLs.
+
+| Selector                            | Purpose                                                                                                                                                               | Source |
+|-------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------|
+| `getpdo CurrentSystemConfiguration` | Echoes the resolved URL set, including margeServerUrl/bmxRegistryUrl/statsServerUrl/swUpdateUrl. We grep our targetURL out of this to confirm a successful migration. | S6     |

+
+## The `scm` family — service control
+
+`scm` (System Control / Module manager) lets you inspect and restart internal services.
+
+| Command                 | Purpose                                                                                  | Availability   | Source                                                                       |

+| `remote_services on`        | Enable SSH on port 22. Volatile (re-enter after reboot). Response: `remote services on`. **Removed in FW 7.x+**.                                                                         | Old              | S1                                                                               |
+| `local_services on`         | Alternative enablement; works on some firmware where `remote_services` was removed. SA-5 FW 9.x reports `local services on`, but this alone does not appear to grant SSH on most models. | Old, hit-or-miss | S1, [deborahgu/soundcork#141](https://github.com/deborahgu/soundcork/issues/141) |
+| `demo enter` / `mode enter` | Unlocks demo / button-test mode (used historically to recover bricked units).                                                                                                            | Old              | S1                                                                               |

+
+## `help`
+
+Lists the commands available on the running firmware. **Frequently removed** on later firmware — returns `Command not found` on FW 27.x in many of the captures we have. Still worth probing once during preflight: a successful response is a quick way to enumerate what this specific build supports without trial-and-error.

+## Firmware era notes
+
+- **Firmware 1.x–7.x** (S1 era): everything — `help`, `remote_services on`, full `scm`, and an in-shell login prompt. `flarn2006` documents the original Linux insides.
+- **Firmware 8.x–14.x** (S2 era): `remote_services on` removed; `network`, `sys`, `envswitch`, `getpdo` still present. `local_services on` works on some Wave/SA-5 models.
+- **Firmware 27.x** (S5/S6 era — the long-lived "frozen" build that survived through EOS): `help`, `remote_services on`, and `sys ver` removed in some builds; `sys configuration …` and `envswitch …` confirmed working on ST 10, ST 20, ST 300, Wave III, Wave IV. **This is the firmware our migration targets**. The Portable on more recent firmware drops further commands and is the hardest target.
+
+  S5 enumerated the **top-level command roots** that don't return "Command not found" on a vanilla ST 10 (`rhino`) running `27.0.6.46330.5043500`:
+
+  ```
+  key
+  net
+  sys
+  getpdo
+  ```
+
+  Notably absent from that probe: `network`, `envswitch`, `scm`, `ws`, `swupdate`, `remote_services`, `local_services`, `demo`, `mode`, `help`. **However**, other captures on the same firmware family (S6, ST 20 / Wave III / Wave IV) accept `envswitch …`, suggesting either per-model variation in the shipped command table or an SSH/role gate the S5 author didn't trip. Implementations that use `envswitch` should treat its absence as a recoverable preflight outcome (we already do).
+
+  `net` is observed as a valid root by S5 but its sub-commands aren't enumerated; it may be a shorthand alias for `network` on FW 27.x ST 10.
+
+---
+
+## What we use during migration
+
+For quick reference, the exact sequence our `pkg/service/setup.migrateViaTelnet` issues, all on the same connection, in this order:
+
+```
+sys configuration bmxRegistryUrl <serverURL>/bmx/registry/v1/services
+sys configuration statsServerUrl <serverURL>
+sys configuration margeServerUrl <serverURL>
+sys configuration swUpdateUrl    <serverURL>/updates/soundtouch
+envswitch boseurls set <serverURL> <serverURL>/updates/soundtouch
+getpdo CurrentSystemConfiguration
+```
+
+Plus, when pairing a fresh device whose `:8090/setMargeAccount` is missing or wedged, the helper falls back to:
+
+```
+envswitch accountid set <7-digit-id>
+```
+
+Reboot is **not** part of these sequences — it stays a user-initiated action via the existing reboot button, which now accepts `?method=telnet|ssh` and sends `sys reboot` when telnet is picked.
+
+---
+
+## Out of scope here, but worth recording
+
+- **Setup-mode WiFi onboarding via 192.0.2.1.** The community uses this to add a fresh device to a network without the Bose app. Our `soundtouch-service` does not currently automate this, but `network wifi profiles add` is the entry point if we ever do.
+- **Direct preset / playback control via `sys`.** The S4 `bose` script demonstrates a viable headless remote-control path that does not need our marge emulation at all. Useful as a fallback for tooling on devices that refuse to talk to any cloud.
+- **`scm restart <service>`.** Not used today, but a possible recovery primitive on older firmware where a stuck service blocks streaming.

+This document captures the use cases, community findings, and feasibility analysis
+for adding a **Telnet/port 17000** migration path to `soundtouch-service` as a
+peer of the existing XML and DNS-based methods. The `/etc/hosts` method stays
+deprecated and is intentionally kept off the visible UI options.

+
+## 1. Why a third method is needed
+
+The two currently shipped methods both have hard preconditions that block real
+users:
+
+| Method                                  | Preconditions                                                | Failure modes seen in the wild                                                                                                                                                         |
+|-----------------------------------------|--------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| **XML** (`SoundTouchSdkPrivateCfg.xml`) | SSH/root access — needs `remote_services` USB unlock first   | Some firmware revisions (e.g. SA-5, ST520, latest ST Portable) refuse the USB unlock entirely; `remote_services on` was removed from the telnet command set in firmware 7.x and later. |
+| **DNS** (`resolv.conf` priority hook)   | SSH/root access; service must own port 53 on the LAN gateway | Won't fit users behind ISP routers they can't reconfigure; still requires the device to be SSH-reachable to write the hook.                                                            |
+
+The community has demonstrated a **third path that needs no SSH at all**:
+the device's built-in **diagnostic Telnet shell on TCP port 17000** accepts
+configuration commands that change exactly the same fields the XML method would.
+
+### 1.1 Confirmed user reports (firmware 27.0.6.46330.5043500 unless noted)
+
+| Reporter           | Hardware                  | Outcome                                                                                                     |
+|--------------------|---------------------------|-------------------------------------------------------------------------------------------------------------|
+| `foob61451` (#221) | ST 10, ST 20 (non-rooted) | All four URLs persisted via `sys configuration …`; `envswitch boseurls set …` survived `sys reboot`.        |
+| `bveenker` (#221)  | Wave III                  | URLs accepted; presets work after pairing via `/setMargeAccount` (see §3).                                  |
+| `stephan48` (#221) | Wave IV                   | Telnet:1700 + USB stick `remote_services` did **not** work; **port 17000 telnet** worked for all four URLs. |
+| `mcdona1d` (#141)  | ST 20, ST 300             | Confirmed working with `sys configuration …` + `envswitch …` + `sys reboot`.                                |
+| `TJGigs` (#228)    | ST 20 ×2, ST 10           | Wraps telnet:17000 into an admin "Smart Inject" tool; uses `sys reboot` over telnet to nudge devices.       |
+
+So the method is plausible across **at least ST 10/20/300 and Wave III/IV** on
+the most common firmware that survived the EOS cut, **without the USB unlock
+dance** that newer firmware refuses.
+
+---
+
+## 2. The Telnet:17000 command set we rely on
+
+> For a broader catalogue of every telnet command the community has documented
+> across firmware eras (the `key`, `network`, `sys`, `envswitch`, `getpdo`,
+> `scm`, `ws`, `swupdate`, and shell-unlock families), see
+> **[TELNET-COMMAND-REFERENCE.md](TELNET-COMMAND-REFERENCE.md)**. This
+> section only lists the subset our migration actually drives.
+
+
+### 2.1 URL configuration (the migration payload)
+
+The sequence we send for `soundtouch-service` (community-validated in #221, #141):
+
+```
+sys configuration bmxRegistryUrl http://<service-host>:8000/bmx/registry/v1/services
+sys configuration statsServerUrl http://<service-host>:8000
+sys configuration margeServerUrl http://<service-host>:8000
+sys configuration swUpdateUrl    http://<service-host>:8000/updates/soundtouch
+envswitch boseurls set http://<service-host>:8000 http://<service-host>:8000/updates/soundtouch
+getpdo CurrentSystemConfiguration
+```
+
+`sys reboot` is **not** part of this sequence. The migration flow only writes
+configuration — the reboot is user-initiated via the existing reboot button in
+the web UI, mirroring what XML/DNS migration already does. See §6.2 for how
+that button gains a `?method=ssh|telnet` selector.
+
+Three important details from the discussion:
+
+1. **`sys configuration` alone is not enough.** `stephan48` reported that
+   without the `envswitch boseurls set …` line his typo in `bmxRegistryUrl` was
+   silently restored on reboot — i.e. there is a parallel "envswitch" persistence
+   layer that wins on next boot if you don't also write to it. **We must always
+   issue both.**
+2. **margeServerUrl path is bare for `soundtouch-service`.** We mount the marge
+   endpoints at the **root** of port 8000, matching what the existing XML
+   migration writes (`Manager.migrateViaXML` in `pkg/service/setup/setup.go`
+   sets `MargeServerUrl: targetURL` without any suffix). Some community
+   recipes appended `/marge` because they were targeting
+   [`deborahgu/soundcork`](https://github.com/deborahgu/soundcork), which
+   routes marge under that sub-path. **For our service: bare URL. For users
+   redirecting to soundcork: append `/marge`** to both `margeServerUrl` and
+   the first argument of `envswitch boseurls set`.
+3. **Each command must be sent one at a time, waiting for the device's `OK`
+   response** before sending the next one (`foob61451`'s explicit warning).
+
+### 2.2 Account pairing fallback
+
+`envswitch accountid set <numeric-id>` was reported by `bveenker` (#221) as an
+in-band equivalent to the HTTP `/setMargeAccount` call, useful when the
+`/setMargeAccount` endpoint is missing on the firmware (see §3).
+
+### 2.3 Probing / preflight
+
+- A bare TCP connect to `<deviceIP>:17000` answers (no auth) on devices we care
+  about.
+- Useful read-only verification command: `getpdo CurrentSystemConfiguration` —
+  prints the URLs after the changes have been applied so we can verify before
+  rebooting.
+- `sys reboot` is the trigger that re-reads both layers.
+
+### 2.4 What Telnet:17000 cannot do
+
+- It does **not** install a custom CA. So if a user wants HTTPS rather than HTTP
+  redirection to our service (the DNS-method scenario, where `resolv.conf`
+  redirection collides with the device's TLS validation unless our root CA is
+  trusted on the device), telnet alone won't cover it. This is fine for our
+  default flow, which uses plain `http://` URLs to the service's port 8000.
+- It does not give us a way to read or write `Sources.xml` (third-party
+  account credentials) — that still requires SSH, but for a migration we don't
+  actually need it.
+
+---
+
+## 3. The `/setMargeAccount` problem (issue #236, #228)
+
+### 3.1 What it is
+
+A factory-reset speaker has an empty `<margeAccountUUID/>` in `:8090/info`. The
+marge endpoints fail with 502 / unhandled until that field is populated, which
+is why several users (#221, #236) saw **everything except AUX** broken after
+migration:
+
+```
+POST http://<deviceIP>:8090/setMargeAccount
+Content-Type: application/xml
+
+<PairDeviceWithAccount>
+  <accountId>1234567</accountId>
+  <userAuthToken>soundcorkdoesntcare</userAuthToken>
+</PairDeviceWithAccount>
+```
+
+The values are not validated by the local service, so any numeric `accountId`
+will work — soundcork's runbook (#228) literally calls the token
+`soundcorkdoesntcare` to make the point.
+
+### 3.2 Why it's broken in practice
+
+There are **three independent failure modes** observed:
+
+| Symptom                                                         | Cause                                                                                                                 | Detection                                                                                                           |
+|-----------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------|
+| Endpoint returns 404 / "not implemented"                        | Newer firmware (e.g. some BST20 Portable, latest ST Portable) drops the endpoint entirely.                            | `GET /supportedURLs` does **not** list `/setMargeAccount` in `<URL location="…"/>`.                                 |
+| Endpoint hangs (no response / socket stays open)                | "Broken state" the user explicitly called out — endpoint advertised, but handler is wedged.                           | Caller has to time out; we currently have no timeout, so the request appears to hang the migration UI indefinitely. |
+| `POST /marge/streaming/support/power_on` → 502 unhandled (#236) | Device keeps polling marge after migration but no `margeAccountUUID` was ever assigned, so all subsequent calls fail. | `:8090/info` shows `<margeAccountUUID/>` empty after reboot.                                                        |
+
+### 3.3 Required handling
+
+Per the user's brief, the migration logic must:
+
+1. **Probe** `GET http://<deviceIP>:8090/supportedURLs` and check whether
+   `/setMargeAccount` is in the list **before** trying to POST it.
+2. **Time-bound** the POST aggressively (e.g. ≤5s connect + ≤10s read) and treat
+   anything over the budget as a failure rather than waiting indefinitely.
+3. On either failure mode, **fall back** to the telnet equivalent
+   `envswitch accountid set <id>` over the same `pkg/telnet` connection used
+   for the URL flip. Reboot stays a user-initiated action (§6.2).
+4. If telnet:17000 is **also** unreachable, surface a clear "your firmware does
+   not support unattended pairing — please pair manually via the official Bose
+   app *before* it goes EOS, or open SSH and use the XML method" error rather
+   than leaving the device in a half-migrated state.
+
+### 3.4 Where the `<id>` comes from
+
+The device's current account ID is already discoverable through endpoints we
+control:
+
+- **`GET :8090/info`** returns `<margeAccountUUID>…</margeAccountUUID>`. If it
+  is non-empty the device is already paired — **reuse that ID**, do not
+  reassign. Our local marge accepts any ID, so the existing one is fine.
+- If it is empty (factory reset), the user picks one in the UI:
+  1. **Pick from existing accounts.** The setup UI lists IDs returned by
+     `DataStore.ListAccounts()` so a user can re-attach a fresh device to an
+     account that already has presets/recents/sources.
+  2. **Enter manually.** Free-form text input, validated as **exactly 7
+     numeric digits** (the format every Bose-cloud-issued ID has had in the
+     captures we've seen, and the format the wider community uses in their
+     recipes).
+  3. **Randomize.** A "Generate" button that picks a 7-digit number and
+     re-rolls if it collides with an existing account in the local datastore.
+- **Telnet read-back (best-effort).** `envswitch accountid get` is plausible by
+  symmetry with `envswitch accountid set` (#221) but is not yet confirmed
+  across firmwares. We will probe it during preflight; if it returns a value
+  we cross-check it against `:8090/info` and warn on mismatch.
+
+This means the user is never *forced* to invent a number — the common path is
+"the device already has an ID, reuse it" — and the manual/randomize controls
+only show up when the device is genuinely fresh.
+
+---
+
+## 4. Port 17000 availability
+
+The diagnostic shell is gated by firmware build and product family. Anecdotally:
+
+- ST 10 / ST 20 / ST 300 / Wave III / Wave IV on FW 27.0.6 → **open**.
+- SA-5 with FW 9.x → some commands present (`local_services on`) but
+  **no `remote_services on`** and no SSH on FW 9.0.43.23466 (#141).
+- Modern firmware on some Portables → endpoint set has shrunk further.
+
+Because of this, we cannot assume port 17000 is reachable. The migration flow
+must:
+
+1. **Probe** with a TCP connect to `<deviceIP>:17000`, with a tight timeout
+   (≤2s). A successful TCP handshake is necessary but not sufficient — some
+   hardened firmware closes the port immediately.
+2. **Banner check.** After connecting, read whatever the device sends within
+   ~1s. The diagnostic shell prints a small banner (firmware-dependent); a
+   blank read or an immediate close means we should treat it as "telnet not
+   usable" and disable the option.
+3. **Capability check.** Issue a no-op like `getpdo CurrentSystemConfiguration`
+   and look for any non-empty response. If the device replies "Command not
+   found" we abort and suggest XML or DNS instead.
+4. **Surface state to the UI.** The migration form should grey out the Telnet
+   option when the probe fails and show *why* (closed, banner missing,
+   command rejected) instead of letting the user click into a dead end.
+
+---
+
+## 5. Implementation feasibility — Telnet client in Go
+
+This is a feasibility check only; no code is written yet.
+
+### 5.1 Protocol
+
+"Telnet" on port 17000 is effectively a line-oriented plain-TCP shell. The
+device prints a small prompt (`->` in the SA-5 captures from #141) and reads
+newline-terminated commands. There is **no** real Telnet option negotiation
+(no `IAC`/`DO`/`WILL` exchanges visible in the wild captures), so we don't
+need `golang.org/x/crypto/ssh`-class machinery.
+
+### 5.2 Standard-library only
+
+A minimal client is just `net.DialTimeout("tcp", host+":17000", 2*time.Second)` +
+`bufio.Scanner` + `time.Time`-based deadlines on `Conn`. No third-party Telnet
+library is needed; `github.com/reiver/go-telnet` would be overkill and adds
+maintenance surface for no benefit. This matches the project's KISS principle
+in `docs/CLAUDE.md` §3.
+
+### 5.3 Cross-platform compatibility
+
+`net.Dial` over TCP works identically on Windows, macOS, Linux and (with
+limitations on listening) WASM. WASM-side: `soundtouch-service` runs server-side
+anyway, so this only matters for `soundtouch-cli`, where TCP dial works in any
+target other than browser-WASM — an acceptable carve-out documented separately.
+
+### 5.4 Concurrency / safety
+
+Each migration is a single goroutine driving one device. The client must:
+
+- enforce per-command response deadlines so a wedged device cannot stall the
+  migration UI (mirrors the `/setMargeAccount` requirement);
+- abort the rest of the sequence on the first non-`OK` response so we don't
+  half-write configuration;
+- always close the socket on error.
+
+### 5.5 Testing strategy
+
+We can test without a real speaker by spinning up a `net.Listen("tcp", "127.0.0.1:0")`
+in the test, scripting it to consume our commands and emit canned `OK`/error
+responses. That gives us deterministic coverage for:
+
+- happy path (all four URLs accepted),
+- single-command failure → sequence aborts, no further commands sent,
+- "command not found" on `envswitch …` → fallback path exercised,
+- TCP closed mid-stream → migration aborts cleanly,
+- read deadline triggers when the device hangs (the broken-state simulation).
+
+The repo already follows the "real device responses preferred, mock servers
+otherwise" rule (see `docs/CLAUDE.md` §1, §8). The tests above are the mock-server
+half of that pattern.
+
+### 5.6 Where it lives
+
+The protocol client is **a standalone package**, not buried inside
+`pkg/service/setup`, so it can be reused from CLI tools, future setup wizards,
+and tests without dragging the migration manager in:
+
+```
+pkg/telnet/                        # NEW reusable package
+  client.go                        #   Dial / SendCommand / Probe / Close
+  client_test.go                   #   mock-server tests against a net.Listen
+
+pkg/service/setup/
+  telnet_migration.go              # NEW thin wrapper that imports pkg/telnet
+                                   # and runs the URL config sequence
+  marge_pairing.go                 # NEW /setMargeAccount probe + post + telnet
+                                   # `envswitch accountid set` fallback
+  setup.go                         # add MigrationMethodTelnet const + case
+```
+
+UI plumbing is `pkg/service/handlers/web/index.html` (option list) and
+`pkg/service/handlers/web/js/script.js` (`toggleMigrationMethod()`). The
+deprecated `hosts` option is already hidden from the dropdown when we ship
+this; we just add a `telnet` option next to `xml`/`resolv`.
+
+### 5.7 Verdict
+
+**Feasible and small.** Estimated scope: ~200 lines of client code in
+`pkg/telnet`, ~300 lines of tests, plus a `MigrationMethodTelnet` branch in
+`Manager.MigrateSpeaker`, plus the preflight probe described in §4 and the
+`/setMargeAccount` guarding described in §3.
+
+---
+
+## 6. Decisions made (was: open questions)
+
+1. **Account-ID generation.** Resolved — see §3.4. The migration form reads
+   `:8090/info` first; if `margeAccountUUID` is non-empty it is reused.
+   Otherwise the UI offers (a) pick from `DataStore.ListAccounts()`,
+   (b) manual entry validated as 7 numeric digits, (c) a "Generate" button
+   that randomizes a 7-digit number and re-rolls on collision.
+2. **Reboot policy.** Migration writes configuration only — it does **not**
+   issue `sys reboot` itself. Reboot stays user-initiated via the existing
+   reboot button in the web UI, the same way XML/DNS migration already works.
+   That button's endpoint (`POST /setup/reboot/{deviceId}`,
+   `Manager.Reboot(deviceIP)`) gains an optional `?method=ssh|telnet` query
+   parameter; default stays `ssh` so existing behavior is preserved. The
+   button itself uses a plain `confirm()` dialog before firing.
+3. **CA / HTTPS story.** Telnet has no way to install a custom CA. Documented
+   as an explicit limitation: telnet method = HTTP-only redirect to our
+   service. Users who need end-to-end TLS must use the XML or DNS method.
+   *Possible future enhancement* — a hybrid "install CA via SSH/XML, then drive
+   the URL flip via Telnet" path. Feasibility unknown; not in this iteration.
+

+
+> **See §9 for the as-shipped state.** Section 7 below records the
+> original forecast; the wizard grew larger during implementation and
+> §9 documents what actually landed.
+
+## 7. Summary of what changes when this lands
+
+- **New reusable package `pkg/telnet`** — sibling of `pkg/ssh`, line-oriented
+  TCP client with `Dial`, `SendCommand`, `Probe`, `Close`, all deadline-driven.
+  No external dependencies, usable from CLI, service, and tests.
+- **New `MigrationMethodTelnet = "telnet"`** constant in `pkg/service/setup/setup.go`
+  plus a `migrateViaTelnet` branch in `Manager.MigrateSpeaker`.
+- **New `pkg/service/setup/telnet_migration.go`** orchestrating the URL
+  configuration sequence (§2.1) on top of `pkg/telnet`. Configuration only —
+  no `sys reboot` here.
+- **New `pkg/service/setup/marge_pairing.go`** with `PairAccount(deviceIP, id)`:
+  probes `/supportedURLs`, time-bounded `POST /setMargeAccount`, falls back to
+  telnet `envswitch accountid set <id>` on missing/wedged endpoint.
+- **`Manager.Reboot` and `HandleRebootDevice` gain a method selector** —
+  signature changes to `Reboot(deviceIP string, method RebootMethod) (string, error)`
+  with `RebootMethodSSH` (default, today's behavior) and `RebootMethodTelnet`
+  (sends `sys reboot` over a fresh `pkg/telnet` connection). Handler reads
+  `?method=ssh|telnet` from the query string.
+- **`MigrationSummary` gains** `TelnetReachable`, `TelnetBanner`,
+  `TelnetCommandsAccepted`, `SetMargeAccountSupported`, `CurrentAccountID`,
+  `KnownAccountIDs` so the UI can show preflight outcomes and offer reuse.
+- **UI** — `web/index.html` dropdown gets a `telnet` option (greyed out when
+  preflight fails) and a new pane for picking/entering/randomizing a 7-digit
+  account ID when `:8090/info` reports an empty `margeAccountUUID`. The
+  existing reboot button gets a method selector (radio or dropdown) wired to
+  the new query param, with `confirm()` before firing. The legacy `hosts`
+  option stays out of the dropdown (deprecated).
+
+---
+
+## 8. Device compatibility today
+
+What follows is the current best read on which devices our `migrateViaTelnet`
+flow handles end-to-end, derived from the same six sources catalogued in
+[TELNET-COMMAND-REFERENCE.md](TELNET-COMMAND-REFERENCE.md) plus the issue
+threads cited above. This is migration-outcome perspective; for per-command
+availability see the reference doc.
+
+### 8.1 Proven to work end-to-end
+
+All on the firmware-27.0.6 family, which is what survived through Bose's
+end-of-service cut. Multi-reporter agreement on every row.
+
+| Device   | Reporter(s)                 | Source           | Confirmed                                                                  |
+|----------|-----------------------------|------------------|----------------------------------------------------------------------------|
+| ST 10    | foob61451, TJGigs           | #221, #228       | All four URLs persist; `envswitch boseurls set` survives `sys reboot`      |
+| ST 20    | foob61451, mcdona1d, TJGigs | #221, #141, #228 | Same; multiple independent reports                                         |
+| ST 300   | mcdona1d                    | #141             | `sys configuration` + `envswitch` + `sys reboot` round-trip                |
+| Wave III | bveenker                    | #221             | URLs accepted; presets work after pairing fallback (§3)                    |
+| Wave IV  | stephan48                   | #221             | Port-17000 path **was the only one that worked** — USB-stick unlock failed |
+
+The exact sequence each reporter ran by hand is the sequence our migration
+sends (§2.1). So the migration's happy path is exercised against five
+hardware variants in independent captures.
+
+### 8.2 Proven to need the pairing fallback
+
+Migration of the URLs themselves works on these models, but
+`POST /setMargeAccount` is missing or wedged on the firmware build, so
+pairing has to go through the telnet `envswitch accountid set <id>` path
+that `setup.PairAccount` already implements.
+
+| Device                         | Reporter | Source                      | Why fallback is needed                                                                                                                                   |
+|--------------------------------|----------|-----------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------|
+| ST Portable / FW 27.0.6        | jmosen   | #236                        | After migration: `POST /marge/streaming/support/power_on` → 502; `<margeAccountUUID/>` empty. Time-bounded HTTP path fails; envswitch fallback succeeds. |
+| BST20 Portable (factory reset) | ubittner | scheilch/opencloudtouch#167 | `<margeAccountUUID/>` empty; `/setMargeAccount` not in `/supportedURLs`. HTTP path skipped entirely; only the telnet fallback works.                     |
+
+### 8.3 Likely to fail (but the failure is clean)
+
+Our preflight + abort-on-first-rejection design (`TestMigrateViaTelnet_CommandNotFoundAborts`)
+means none of these scenarios leave a device half-configured. The user is
+told what failed and pointed to the XML or DNS method.
+
+| Device                                     | Source          | Likely cause                                                                                                                                                                                                                             |
+|--------------------------------------------|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| **SA-5** (sound amplifier) on FW 9.0.43.x  | soundcork#141   | FW 9.x has a different shell generation: `->` prompt, `local_services on`, `scm uboot_ver`. **`sys configuration` and `envswitch` are not documented as working there.** Migration fails on command #1.                                  |
+| **Recent ST Portable** (post-27.0.6.46330) | #236 (indirect) | `/setMargeAccount` removal points to broader command-set shrinkage. If `envswitch accountid set` is also gone, both migration and pairing fallback fail; user is told to pair via the official Bose app before EOS, or use XML over SSH. |
+
+### 8.4 Unknown — would benefit from real-device verification
+
+| Device                     | Why unknown                                                         | What we'd want to confirm                                                |
+|----------------------------|---------------------------------------------------------------------|--------------------------------------------------------------------------|
+| **ST 30** (`mojo`)         | No concrete capture in any of the six sources                       | Almost certainly works — same FW family as ST 10/20/300 — but unverified |
+| **ST 520 / Home Cinema**   | USB-unlock reports failing (#141), no port-17000 capture either way | Whether `sys configuration` and `envswitch` are exposed at all           |
+| **Wave Music System I/II** | `flarn2006`-era hardware, not seen in 27.x reports                  | Whether port 17000 is even open on those models                          |
+
+### 8.5 The S5 "valid roots" tension
+
+S5 (the r/bose telnet-probing thread) lists only `key`, `net`, `sys`,
+`getpdo` as command roots that don't return "Command not found" on its
+ST 10 / FW 27.0.6 — which would seem to rule out `envswitch`. But foob61451
+on the same hardware/firmware ran `envswitch boseurls set` successfully
+(#221).
+
+The most plausible reading is that **S5 is a non-exhaustive probe**, not a
+negative claim: the author writes "I've made some educated guesses and come
+up with the following valid commands" and never says they tested
+`envswitch`. We do not down-weight `envswitch` availability on the strength
+of S5 alone — but if a real-device run ever shows `envswitch` rejected on
+an ST 10, our preflight catches it, the migration aborts on the first
+non-OK response, and the user gets a clear error rather than partial state.
+
+### 8.6 Failure-mode matrix
+
+What `migrateViaTelnet` does in each failure mode (verified by
+`pkg/telnet` and `pkg/service/setup` unit tests):
+
+| Failure                                        | Outcome                                                                                           | Test                                                                                                               |

+
+### 8.7 TL;DR
+
+- **Green light** — ST 10, ST 20, ST 300, Wave III, Wave IV on FW 27.0.6 (multi-reporter agreement).
+- **Yellow** — ST Portable and BST20 Portable: migration works, pairing needs our fallback (already implemented).
+- **Red, but fails cleanly** — SA-5 on FW 9.x, possibly newer ST Portable builds.
+- **Unverified but expected to work** — ST 30, ST 520, Wave Music System I/II.
+
+The most useful next verification step is touching a real ST 30 and ST 520
+— those are the two "expected to work" models with zero concrete captures.
+Beyond that, every behaviour the doc predicts is exercised by the unit
+tests in `pkg/telnet` and `pkg/service/setup`.
+
+---
+
+## 9. What actually shipped (post-implementation addendum)
+
+§7 forecast the surface area roughly; the wizard ended up larger. This
+section is the present-day map of the migration tab and the supporting
+backend pieces — kept appended rather than rewritten in place so the
+feasibility analysis above stays a faithful design record.
+
+### 9.1 Three-axis state model
+
+`MigrationSummary` now exposes the four mechanism-specific booleans
+that `checkIsMigrated` writes individually:
+
+- `XMLMigrated` — parsed SoundTouchSdkPrivateCfg.xml's URLs point at us.
+- `HostsMigrated` — `/etc/hosts` carries Bose-domain redirects (the
+  deprecated method, kept detectable for legacy speakers).
+- `ResolvMigrated` — the `/etc/resolv.conf` priority-nameserver hook
+  is in place (with CA trusted).
+- `TelnetMigrated` — `getpdo CurrentSystemConfiguration` reports the
+  service hostname.
+
+`IsMigrated` is the OR. Plus `IsPaired` from the live
+`:8090/info.margeAccountUUID` value.
+
+The frontend opens with a state card that surfaces three orthogonal
+axes derived from these flags:
+
+| Axis              | Verdict semantics                                                                                                     |
+|-------------------|-----------------------------------------------------------------------------------------------------------------------|
+| URL Configuration | URL flip active → ✅; original Bose URLs + DNS hook active → ✅ (intercepted); original + no DNS → ❌ (not intercepted). |
+| DNS Interception  | None / resolv.conf hook / /etc/hosts (with deprecated badge).                                                         |
+| CA / TLS          | Local root CA installed yes/no.                                                                                       |
+
+Plus a Preconditions row: `remote_services` persistence, account
+pairing state, XML config backup presence. Action affordances
+(`Trust CA Now`, `Download CA cert`) live inline next to their verdicts.
+
+### 9.2 Plan card with per-field URL editor
+
+Replaces the XML method's `self/proxied/original` dropdowns and the
+duplicate URL inputs that used to live inside the telnet method pane:
+
+- Target service URL input with `Save as default` (POSTs to
+  `/setup/settings`, preserving the `***` secret-unchanged convention).
+- Capabilities header: detected transports (SSH / Telnet:17000) and
+  the recipes AfterTouch can offer given those transports.
+- Service URLs table: four free-form URL inputs (Marge / Stats /
+  SwUpdate / BmxRegistry) with on-keystroke validation
+  (`validatePlanURLs`), a Soundcork-mode checkbox that flips `/marge`
+  on `margeServerUrl`, and a `Reset to defaults` button.
+- Account pairing section: ID input + Generate + datastore picker;
+  the implicit intent (`readPlanPairTarget`) queues a pair step at
+  Apply when the input differs from the current `account_id`.
+- Suggested plan box: one-click conservative default — XML + HTTP
+  when SSH works, Telnet + HTTP otherwise; "Already migrated" info
+  state when `IsMigrated` is already true.
+
+The per-field URLs feed both XML and Telnet migrations via the
+`marge_url` / `stats_url` / `sw_update_url` / `bmx_url` option family
+(see §9.6). Live preview rewrites `#planned-config` purely client-side
+on every keystroke — optimistic; the backend's perspective gates the
+write via §9.4's pre-flight.
+
+### 9.3 Customize three-axis form
+
+The `<details>` "Customize this migration" section replaces the old
+migration-method dropdown with three independent radio groups:
+
+1. **URL flip transport**: XML / Telnet:17000 / Skip.
+2. **DNS interception**: None / `/etc/resolv.conf` hook.
+3. **Local CA install**: checkbox.
+
+Each option carries a per-axis availability hint
+(`(SSH unreachable)`, `(already trusted)`, etc.) so users see *why*
+an option is disabled. `applyCustomPlan` orchestrates the chosen
+combination as a sequence of existing backend calls
+(`/setup/migrate?method=…` for each flip/resolv step plus
+`/setup/trust-ca` for standalone CA install, and the queued pair
+step from §9.2). Resolv already bundles a CA install, so a redundant
+standalone CA step is skipped. First failure aborts the rest.
+
+### 9.4 Pre-flight panel
+
+Both Apply paths run a visible pre-flight panel before any backend
+operation touches the speaker. Each check renders inline with the
+🕐 / ⟳ / ✅ / ❌ / — idiom. On all-green the panel holds for ~700ms so
+the success state registers, then auto-proceeds. On any failure the
+panel surfaces `Proceed Anyway` / `Cancel` buttons; default is to
+abort.
+
+Checks:
+
+| Check                                 | When                                                       | Backend route                  |
+|---------------------------------------|------------------------------------------------------------|--------------------------------|
+| Backend summary re-check              | always                                                     | `GET /setup/summary`           |
+| HTTPS connection from device          | `ssh_success && server_https_url`                          | `POST /setup/test-connection`  |
+| Reachability check (passive observer) | `telnet_reachable && is_migrated` (see §9.8)               | `POST /setup/peer-probe`       |
+| Round-trip skip explainer             | `telnet_reachable && !is_migrated` — runs after reboot     | _none_ (UI-side skip row)      |
+| DNS redirection from device           | `methods.includes("resolv") && ssh_success`                | `POST /setup/test-dns`         |
+
+The HTTPS check uses `use_explicit_ca=true` so it exercises the trust
+path even when CA install is part of the plan (i.e. forward-looking).
+The reachability skip row is explicit ("neither SSH nor Telnet:17000
+is reachable") rather than silently dropped, per the user's
+"feedback always visible" requirement.
+
+### 9.5 Telnet round-trip probe — the SSH-less reachability check
+
+> **REMOVED — see §9.8.** Empirical testing showed the swUpdate
+> daemon caches its target URL at boot and ignores live config
+> writes, so the active flip described below could never reach the
+> running daemon. The section is retained as a historical record of
+> what was tried; the running code uses the passive observer in §9.8.
+
+The reachability gap §7 left open for USB-unlock-refusing speakers is
+closed by `Manager.RunTelnetRoundTripProbe`
+(`pkg/service/setup/telnet_probe.go`). Sequence:
+
+1. Telnet `getpdo CurrentSystemConfiguration` to capture the
+   speaker's current `swUpdateUrl`.
+2. Generate a random 24-hex-char token; register a one-shot signal
+   channel under it on the new `probeRegistry` (sibling field on
+   `handlers.Server`).
+3. Telnet `sys configuration swUpdateUrl <targetURL>/probe/<token>`
+   — **runtime layer only, deliberately not `envswitch boseurls set
+   …`**. The persistence layer keeps the original URL, so a reboot
+   heals the device naturally if our restore step fails.
+4. `HTTP GET <deviceIP>:8090/swUpdateCheck` — the cleanest
+   `:8090` endpoint that triggers exactly one outbound to the
+   configured `swUpdateUrl`. Read-only on the cloud side
+   (doesn't initiate an update); independent of `margeAccountUUID`
+   so it works on factory-reset speakers.
+5. Wait on the registered channel up to `telnetProbeTimeout` (6s).
+6. Telnet `sys configuration swUpdateUrl <originalURL>` — deferred
+   restore so it runs even on the failure path.
+
+The new `/probe/{token}[/*]` catch-all on the root router signals the
+matching channel when the speaker's outbound lands. The response is
+a minimal `<swUpdateIndex/>` so the speaker's `swUpdateCheck`
+doesn't choke on a missing structure. The `/*` sub-path is
+registered because some firmware appends a path component to the
+configured `swUpdateUrl`.
+
+### 9.6 Backend additions worth knowing

+
+### 9.7 Future probe candidates
+
+- `:8090/pushCustomerSupportInfoToMarge` — flagged as a potential
+  "ask the device about itself" probe that could feed a richer
+  device-info pane (firmware build dates, hardware revisions). Not
+  implemented.
+- Running the round-trip probe on SSH-capable speakers too (as
+  additional validation alongside the curl-from-device HTTPS test),
+  not just as the SSH-less fallback it is today. **Subsumed by §9.8
+  — the round-trip probe is being removed; the passive observer is
+  transport-agnostic and replaces it for migrated speakers.**
+
+### 9.8 The swUpdate daemon-cache finding and removal of §9.5
+
+The §9.5 round-trip probe was retired after empirical testing on a
+fully-migrated speaker (FW 27.0.6) revealed that the `swUpdate`
+daemon **caches its target URL at boot and ignores live config
+writes**. The diagnostic sequence:
+
+1. Manual telnet flip of both layers — `sys configuration swUpdateUrl
+   <probe-url>` (runtime) **and** `envswitch boseurls set <marge>
+   <probe-url>` (persistence). `getpdo CurrentSystemConfiguration`
+   confirmed both writes stuck.
+2. HTTP GET `:8090/swUpdateCheck` to trigger fan-out.
+3. Service access log showed the device outbound landed on
+   `/updates/soundtouch` (the **previous** `swUpdateUrl` value, current
+   at the last daemon boot) and `/streaming/software/update/account/<id>`
+   (a separate Bose URL the daemon hits, routed to this service by DNS
+   interception). The probe URL was never dialed.
+
+This falsifies the original NEXT.md hypothesis that the persistence
+layer would override the runtime layer for the daemon's fan-out, and
+points instead at daemon-level URL caching. Two consequences:
+
+- **The §9.5 probe cannot work on migrated speakers without a
+  reboot.** The cached URL is set when the daemon starts; flipping
+  config after that point has no effect on what the daemon dials.
+- **The §9.5 probe likely cannot work on unmigrated speakers
+  either**, for the same reason — the daemon caches whatever URL it
+  read at startup, which on an unmigrated speaker is the Bose cloud
+  URL. We have no service running with the probe URL registered on
+  unmigrated speakers, so the original "it worked in testing" claim
+  has no empirical basis; it likely failed silently because nothing
+  was watching.
+
+The honest replacement is a **passive observer** (see
+`pkg/service/setup/peer_probe.go`):
+
+1. Register the device IP with an in-process observer
+   (`handlers.peerObserver`, wired via `PeerObserverMiddleware`).
+2. Nudge `:8090/swUpdateCheck` to make the daemon fan out *something*
+   sooner than its ~5min timer.
+3. Wait up to 30s for any inbound from that IP. On a migrated
+   speaker, DNS interception means the daemon's outbounds (update
+   fan-out, marge polls, BMX registry calls) all funnel through this
+   service regardless of which URL the daemon resolved internally —
+   so reachability reduces to *"did the device dial us at all."*
+
+Endpoint: `POST /setup/peer-probe/{deviceId}`. No device-state
+mutation; safe to re-run. Returns `{ok, result: {reached,
+observed_path, elapsed_ms}, error}` with the same UI keying as the
+old probe (`result.reached`).
+
+#### 9.8.1 The pre-flight panel branch
+
+The web UI's pre-flight orchestrator (`runApplyPreflight` in
+`script.js`) branches on `summary.is_migrated`:
+
+| Migration state                   | Reachability row                                                                                                             |
+|-----------------------------------|------------------------------------------------------------------------------------------------------------------------------|
+| Migrated (`is_migrated=true`)     | "Reachability check (passive observer)" — calls `POST /setup/peer-probe/{deviceId}`.                                         |
+| Not migrated (incl. partial)      | Skip row "Round-trip validation runs after Apply + reboot" with the rationale "daemon caches swUpdateUrl at boot".           |
+
+Per-axis booleans (`xml_migrated`, `hosts_migrated`, `resolv_migrated`,
+`telnet_migrated`) remain visible in the State card, so the user can
+see which parts of the migration are already in place even when the
+overall flag is false. The skip row does not attempt the active probe
+on unmigrated speakers — the canonical telnet flow is:
+
+```
+Apply telnet config → user-initiated reboot → re-run pre-flight on
+the now-migrated speaker → passive observer confirms fan-out.
+```
+
+#### 9.8.2 Removal trail
+
+Removed (or scheduled for removal in a follow-up commit) at the time
+of §9.8 landing:
+
+- `pkg/service/setup/telnet_probe.go` — `RunTelnetRoundTripProbe`,
+  `ProbeRegistrar`, `TelnetProbeResult`, `generateProbeToken`.
+- `pkg/service/handlers/handlers_telnet_probe.go` — `HandleTelnetProbe`,
+  `HandleProbeInbound`, `telnetProbeTimeout`, `telnetProbeResponse`.
+- `pkg/service/handlers/probe_registry.go` — `probeRegistry` + tests.
+- `Server.probes` field.
+- Routes `/probe/{token}`, `/probe/{token}/*`, `/setup/telnet-probe/{deviceId}`.
+- The `target_url` query-param plumbing on the deprecated endpoint.
+- `script.js` — `checkTelnetRoundTrip` (orchestrator call site removed
+  in the commit that added the branch; function itself removed later).
+
+`isCommandNotFound` and `parseGetpdoConfig` stay — they are also used
+by the migration writer (`telnet_migration.go`), preflight reader
+(`telnet_preflight.go`), pairing path (`marge_pairing.go`), and
+cross-check (`preflight_crosscheck.go`).

+# 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 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 ↔ AfterTouch
+
+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:
+

+|--------------------------|---------------------------------------|-----------------------------------------------------------|
+| Web UI                   | FastAPI + Jinja2 miniapp and admin UI | Separate `soundtouch-web` component (Go + plain HTML/JS)  |
+| Direct device management | SSH/SCP access into speakers          | HTTP API only; no SSH                                     |
+| Device discovery client  | Python `upnpclient` library           | mDNS + UPnP in Go, with dedicated DNS interception server |
+| Token delivery           | Push (ZeroConf priming to port 8200)  | Pull (device calls back to fetch)                         |
+| Persistence format       | Flat files                            | XML flat files + atomic writes                            |
+
+### AfterTouch capabilities soundcork lacks

+| HTTPS / custom CA injection               | Full TLS with certificate generation and trust workflow         |
+| HTTP interaction recording & replay       | Captures real device traffic for debugging and regression tests |
+| Device migration (serial → MAC path)      | Handles legacy device ID formats automatically                  |
+| Transparent proxy mode with upstream sync | Can mirror to real Bose cloud while running locally             |
+| CLI (`soundtouch-cli`)                    | Scriptable control of speakers                                  |
+| Importable Go library                     | `github.com/gesellix/bose-soundtouch/pkg/client`                |

+
+### 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.
+
+---
+
+## Endpoints
+
+| Method | Path                                                        | Auth  | Purpose                                            |

+| `POST` | `/mgmt/amazon/init`                                         | Basic | Start OAuth flow, returns authorization URL        |
+| `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.

+# Capture Device Pairing Traffic
+
+Step-by-step runbook for factory-resetting a SoundTouch speaker, pairing it to a Bose cloud account, and capturing every cloud request via mitmproxy. Tested on Apple Silicon Mac.
+
+**Goal:** obtain a full `.mitm` recording of the account-pairing flow (streaming.bose.com) triggered by the official Android app.
+
+---
+
+## Overview
+
+```
+Phase 0  Pre-flight checks
+Phase 1  Factory reset speaker
+Phase 2  Provision speaker Wi-Fi (AP mode, console)
+Phase 3  Start mitmproxy + emulator + Frida
+Phase 4  Pair speaker via Bose app (adb-driven)
+Phase 5  Save & inspect recording
+```
+
+The Android emulator does not have Bluetooth, so the standard BLE setup path is unavailable. Instead:
+
+1. Provision Wi-Fi directly over the speaker's AP web server (Phase 2).
+2. Once the speaker is on the LAN, the Bose app discovers it via mDNS — no BLE needed.
+
+---
+
+## Phase 0 — Pre-flight
+
+The emulator setup is fully scripted. Run once per machine:
+
+```bash
+# Place the Bose APK at scripts/android/bose.apk first (see BOSE-APP-ADB-Emulator.md § 1)
+# Run mitmweb once to generate the CA: mitmweb --listen-port 8080 (Ctrl-C after it starts)
+
+scripts/android/setup-mitm-avd.sh
+```
+
+This installs the system image, creates an AVD named `bose-mitm`, installs the
+mitmproxy cert and Bose APK, and saves an emulator snapshot `mitm-ready` — so
+subsequent sessions never repeat the cert/reboot cycle.
+
+For subsequent sessions, Phase 3 below is replaced by a single command:
+
+```bash
+scripts/android/start-mitm-session.sh
+```
+
+Manual steps are only needed if you want to understand the internals; see
+[BOSE-APP-ADB-Emulator.md](../analysis/BOSE-APP-ADB-Emulator.md) for the
+full manual walkthrough.
+
+---
+
+## Phase 1 — Factory Reset Speaker
+
+Perform the reset for your model (see
+[DEVICE-INITIAL-SETUP.md § 5](DEVICE-INITIAL-SETUP.md) for full table):
+
+| Model                       | Sequence                                                                |
+|-----------------------------|-------------------------------------------------------------------------|
+| SoundTouch 10               | Power on; hold **Preset 1** + **Vol −** ~10 s → solid amber Wi-Fi LED   |
+| SoundTouch 20               | Power on; hold **Preset 1** + **Vol −** ~10 s → lights blink L→R, amber |
+| SoundTouch 20/30 Series III | Hold **Preset 1** + **Preset 6** ~10 s                                  |
+| SoundTouch 300              | Hold **Vol −** ~15 s until light bar blinks                             |
+
+Wait until the white LED sweep / restart animation completes (~30 s). The speaker
+is now in setup mode and broadcasting its own Wi-Fi AP.
+
+---
+
+## Phase 2 — Provision Speaker Wi-Fi (AP Mode)
+
+### 2.1 Connect Mac to Speaker AP
+
+```bash
+# Find the SSID — use System Settings → Wi-Fi or:
+#   sudo wdutil info   (macOS Sequoia+, airport command removed)
+
+# Connect (replace SSID with actual value)
+SPEAKER_SSID="Bose SoundTouch XXXX"
+networksetup -setairportnetwork en0 "$SPEAKER_SSID"
+
+# Confirm: speaker web UI reachable at 192.0.2.1 (client gets 192.0.2.2)
+curl -s --connect-timeout 5 http://192.0.2.1/ | head -3
+```
+
+### 2.2 Push Home Wi-Fi Credentials
+
+The setup UI at `http://192.0.2.1/` uses the SoundTouch API on **port 8090**. Push credentials directly:
+
+```bash
+HOME_SSID="MyHomeNetwork"
+HOME_PASS="MyPassword"
+
+# Optional: trigger a site survey first so the speaker finds your SSID
+curl -s -X POST http://192.0.2.1:8090/performWirelessSiteSurvey \
+  -H 'Content-Type: text/xml' \
+  --data-raw '<PerformWirelessSiteSurvey timeout="5"/>'
+
+curl -s -X POST http://192.0.2.1:8090/addWirelessProfile \
+  -H 'Content-Type: text/xml' \
+  --data-raw "<AddWirelessProfile><profile ssid=\"${HOME_SSID}\" password=\"${HOME_PASS}\" securityType=\"wpa_or_wpa2\" /></AddWirelessProfile>"
+```
+
+Expected response: `<AddWirelessProfileResponse />`
+
+### 2.3 Reconnect Mac to Home Network
+
+```bash
+HOME_SSID="MyHomeNetwork"
+HOME_PASS="MyPassword"
+
+networksetup -setairportnetwork en0 "$HOME_SSID" "$HOME_PASS"
+```
+
+### 2.4 Wait for Speaker to Join LAN
+
+```bash
+# Poll mDNS until the speaker appears (~15-30 s)
+echo "Waiting for speaker on LAN..."
+until dns-sd -B _soundtouch._tcp local 2>&1 | grep -m1 "Add"; do sleep 2; done
+echo "Speaker is online"
+
+# Resolve its IP
+dns-sd -L "$(dns-sd -B _soundtouch._tcp local 2>&1 | grep Add | awk '{print $7}')" \
+  _soundtouch._tcp local 2>&1 | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'
+```
+
+Or just scan for open port 8090:
+
+```bash
+# Quick scan of your /24 subnet for port 8090
+SUBNET="192.168.1"   # adjust to your local subnet
+for i in $(seq 1 254); do
+  (ping -c1 -W1 ${SUBNET}.$i &>/dev/null && \
+   nc -z -w1 ${SUBNET}.$i 8090 2>/dev/null && \
+   echo "${SUBNET}.$i") &
+done
+wait
+```
+
+---
+
+## Phase 3 — Start mitmproxy, Emulator, Frida
+
+Run each block in a separate terminal tab.
+
+### 3.1 Start mitmweb (native macOS app)
+
+> **Note:** Docker mitmproxy does not work here — its NAT layer prevents the emulator from reaching it. Use the native macOS app instead (download: `https://downloads.mitmproxy.org/12.2.2/mitmproxy-12.2.2-macos-arm64.tar.gz`).
+
+```bash
+CAPTURE="bose-pairing-$(date +%Y%m%d-%H%M%S).mitm"
+/Applications/mitmproxy.app/Contents/MacOS/mitmweb \
+  --web-host 0.0.0.0 --listen-port 8080 --mode regular \
+  --set web_password=bose \
+  -w "scripts/android/captures/${CAPTURE}"
+# Captures → scripts/android/captures/
+# Web UI   → http://127.0.0.1:8081/?token=bose
+```
+
+### 3.2 Start Emulator
+
+```bash
+~/Library/Android/sdk/emulator/emulator -avd Pixel_6_API33 -writable-system &
+echo "Waiting for emulator boot..."
+adb wait-for-device
+adb -s emulator-5554 wait-for-device shell 'while [[ -z $(getprop sys.boot_completed) ]]; do sleep 1; done'
+echo "Emulator ready"
+```
+
+Enable root and install certificate (only needed once per emulator session):
+
+```bash
+adb -s emulator-5554 root
+adb -s emulator-5554 shell avbctl disable-verification
+adb -s emulator-5554 reboot
+adb -s emulator-5554 wait-for-device
+adb -s emulator-5554 root
+
+HASH=$(openssl x509 -inform PEM -subject_hash_old \
+  -in ~/.mitmproxy/mitmproxy-ca-cert.pem | head -1)
+
+adb -s emulator-5554 push ~/.mitmproxy/mitmproxy-ca-cert.pem /data/local/tmp/mitmproxy.pem
+adb -s emulator-5554 shell su 0 mkdir -p /data/misc/user/0/cacerts-added
+adb -s emulator-5554 shell su 0 \
+  cp /data/local/tmp/mitmproxy.pem /data/misc/user/0/cacerts-added/${HASH}.0
+adb -s emulator-5554 shell su 0 \
+  chmod 644 /data/misc/user/0/cacerts-added/${HASH}.0
+```
+
+Set proxy to Mac IP:
+
+```bash
+MAC_IP=$(ipconfig getifaddr en0)
+adb -s emulator-5554 shell settings put global http_proxy "${MAC_IP}:8080"
+echo "Proxy set to ${MAC_IP}:8080"
+```
+
+Confirm emulator can reach the speaker:
+
+```bash
+SPEAKER_IP=192.168.1.50   # adjust to your speaker's LAN IP
+adb -s emulator-5554 shell ping -c 3 "$SPEAKER_IP"
+```
+
+### 3.3 Start frida-server
+
+```bash
+adb -s emulator-5554 push scripts/android/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 "nohup /data/local/tmp/frida-server > /dev/null 2>&1 &"
+sleep 2
+echo "frida-server running"
+```
+
+### 3.4 Configure config.js
+
+`start-mitm-session.sh` patches `scripts/android/frida/config.js` automatically with the current Mac IP and mitmproxy cert. No manual step needed.
+
+### 3.5 Launch App with SSL Unpinning
+
+```bash
+scripts/android/frida-venv/bin/frida \
+  -U \
+  -f com.bose.soundtouch \
+  -l scripts/android/frida/config.js \
+  -l scripts/android/frida/native-connect-hook.js \
+  -l scripts/android/frida/android/android-system-certificate-injection.js \
+  -l scripts/android/frida/android/android-proxy-override.js \
+  -l scripts/android/frida/android/android-certificate-unpinning.js \
+  -l scripts/android/frida/android/android-certificate-unpinning-fallback.js
+```
+
+> `native-connect-hook.js` is required — the Bose app uses native networking that bypasses Java proxy settings.
+
+Expected Frida output:
+
+```
+== System certificate trust injected ==
+== Proxy system configuration overridden to <IP>:8080 ==
+== Proxy configuration overridden to <IP>:8080 ==
+== Certificate unpinning completed ==
+== Unpinning fallback auto-patcher installed ==
+```
+
+---
+
+## Phase 4 — Pair Speaker via App
+
+The Bose app should now be running in the emulator with all traffic going through mitmproxy.
+
+### 4.1 Inspect UI to Find Interactive Elements
+
+```bash
+# Dump current screen
+adb -s emulator-5554 shell uiautomator dump /sdcard/ui.xml
+adb -s emulator-5554 pull /sdcard/ui.xml /tmp/ui.xml
+
+# Helper: list all clickable elements with their text + bounds
+grep -o 'text="[^"]*" resource-id="[^"]*" \.\.\. clickable="true"[^/]*' /tmp/ui.xml \
+  || python3 -c "
+import xml.etree.ElementTree as ET
+tree = ET.parse('/tmp/ui.xml')
+for n in tree.iter('node'):
+    if n.get('clickable') == 'true' and n.get('text'):
+        print(n.get('bounds'), n.get('resource-id'), repr(n.get('text')))
+"
+```
+
+### 4.2 Navigate Setup Flow (adb)
+
+```bash
+# Take a screenshot at any point to see current state
+adb -s emulator-5554 shell screencap /sdcard/screen.png
+adb -s emulator-5554 pull /sdcard/screen.png /tmp/screen.png
+open /tmp/screen.png
+
+# Tap by resource-id (find IDs from ui.xml dump)
+adb -s emulator-5554 shell uiautomator runtest ... # or input tap
+
+# Tap by screen coordinates
+adb -s emulator-5554 shell input tap X Y
+
+# Type into the focused field
+adb -s emulator-5554 shell input text "your@email.com"
+
+# Press Enter / Next
+adb -s emulator-5554 shell input keyevent 66
+```
+
+### 4.3 Expected Setup Steps in the App
+
+Follow the on-screen flow; mitmproxy captures everything automatically.
+
+1. **Sign in** — enter email + password → triggers `POST /streaming/account/login`
+2. **Add speaker** — tap "Set Up a New Speaker" or equivalent
+3. **App discovers speaker** via mDNS on LAN (no BLE required)
+4. **Wi-Fi already configured** — app skips the Wi-Fi step since speaker is online
+5. **Name speaker** — type a name → WebSocket `name` message to speaker port 8080
+6. **Pairing** — app sends `setMargeAccount` WebSocket to speaker → speaker POSTs to `streaming.bose.com/{accountId}/devices`
+
+All cloud requests (steps 1, 6) will appear in mitmweb at `http://127.0.0.1:8081`.
+
+---
+
+## Phase 5 — Save & Inspect Recording
+
+```bash
+# Stop mitmweb (Ctrl-C in its terminal) — file is already written continuously
+
+# Inspect offline in the web UI
+mitmweb -r "$CAPTURE"
+
+# Filter to streaming.bose.com only
+mitmdump -r "$CAPTURE" --flow-filter '~u streaming.bose.com' -w bose-cloud-only.mitm
+
+# Quick text summary
+mitmdump -r "$CAPTURE" --flow-filter '~u streaming.bose.com' 2>/dev/null \
+  | grep -E "POST|GET" | head -30
+```
+
+### Convert to .http files (IntelliJ-compatible)
+
+Use `scripts/convert_mitm_script.py` to extract each flow as a `.http` file, organized by path:
+
+```bash
+NAME=$(basename "$CAPTURE" .mitm)
+OUT="scripts/android/mitm/${NAME}"
+
+/Applications/mitmproxy.app/Contents/MacOS/mitmdump \
+  -n -r "$CAPTURE" \
+  -s scripts/convert_mitm_script.py \
+  --set out_dir="${OUT}"
+```
+
+Output lands in `scripts/android/mitm/<name>/mirror/` as numbered `.http` files
+plus `*-websocket/` subdirectories for WebSocket frames. The directory is gitignored.
+
+---
+
+## Cleanup
+
+```bash
+# Remove proxy from emulator
+adb -s emulator-5554 shell settings delete global http_proxy
+
+# Kill emulator
+adb -s emulator-5554 emu kill
+```
+
+Frida artefacts live in `scripts/android/` (gitignored) and persist between sessions — no cleanup needed unless you want to force a fresh setup.

+## Session Trace (2026-05-02, ST10)
+
+Raw log of the first interactive run. To be cleaned up into the runbook above.
+
+### Setup
+- Ran `scripts/android/setup-mitm-avd.sh` — all 9 steps completed:
+  - Steps 1–5 were already done from a prior session (idempotent skips)
+  - Step 6: Docker image built, `frida-server` extracted to `scripts/android/frida-server`
+  - Steps 7–9: Emulator started fresh (`-no-snapshot-load`), AVB disabled, rebooted, cert + APK + frida-server installed, snapshot `mitm-ready` saved
+- Emulator running at `emulator-5554`
+
+### Factory Reset (ST10)
+- Correct sequence confirmed from official Bose guide (`firmware/FirmwareUpdateGuide/`):
+  **Power on → hold Preset 1 + Volume − for 10 s → Wi-Fi LED glows solid amber**
+- Note: original docs said "Vol− + Mute" — corrected in DEVICE-INITIAL-SETUP.md and this file
+
+### Pre-reset note
+- User inserted USB device containing `remote_services` before rebooting — device needs to be on home Wi-Fi before the USB config takes effect
+
+### Wi-Fi Provisioning (AP mode)
+- `airport` command not available on this macOS version (removed in recent releases)

+# Capture Speaker Migration Traffic
+
+Runbook for migrating a SoundTouch speaker to `soundtouch-service` and capturing
+all traffic (App→Service and Speaker→Service) to identify unimplemented endpoints.
+
+**Goal:** obtain a complete picture of every cloud request a speaker and the Bose
+app make after migration, so missing endpoint implementations can be tracked down.
+
+**Pre-requisites:** the MITM pipeline is already set up and working. See
+[CAPTURE-DEVICE-PAIRING.md](CAPTURE-DEVICE-PAIRING.md) for the one-time AVD setup
+and the pairing capture runbook.
+
+---
+
+## Overview
+
+```
+Step 1  Start soundtouch-service locally (with interaction recording)
+Step 2  Start a fresh mitmproxy + Frida session (captures App traffic)
+Step 3  Discover or register the speaker in the service UI
+Step 4  Migrate the speaker (modifies SoundTouchSdkPrivateCfg.xml via SSH)
+Step 5  Operate the Bose app — everything now flows through local service
+Step 6  Inspect captured interactions for unimplemented endpoints
+Step 7  Revert (optional) / clean up
+```
+
+Traffic sources:
+- **App → Service** — captured by mitmproxy + Frida (same as pairing capture)
+- **Speaker → Service** — captured by the service's built-in interaction recorder
+
+---
+
+## Step 1 — Start soundtouch-service
+
+Build and start the service. Recording is on by default; add `--server-url` so the
+service knows its own public address (the speaker needs it for redirections).
+
+```bash
+# Determine Mac LAN IP first
+MAC_IP=$(ipconfig getifaddr en0)
+echo "Mac IP: ${MAC_IP}"
+
+# Build + run with explicit server-url so the service embeds the correct address
+make build-service
+./build/soundtouch-service \
+  --server-url "http://${MAC_IP}:8000" \
+  --record-interactions \
+  --log-bodies
+```
+
+Service listens on `:8000` by default. Web UI: `http://localhost:8000`
+
+> To also enable mirror mode (forward unhandled requests to official Bose servers
+> for comparison), add: `--mirror-enabled --mirror-endpoints /streaming/`
+
+---
+
+## Step 2 — Start mitmproxy + Frida (new capture)
+
+In a separate terminal:
+
+```bash
+scripts/android/start-mitm-session.sh
+```
+
+The script prints ready-to-run commands for mitmweb and Frida. Run each in its own
+terminal tab as instructed.
+
+New capture file lands in `scripts/android/captures/`.
+
+---
+
+## Step 3 — Discover the Speaker
+
+Open the service web UI at `http://localhost:8000`.
+
+The service discovers speakers via mDNS automatically on startup. If the speaker
+does not appear within ~30 s, add it manually:
+
+```bash
+# Via API (replace IP with speaker's current LAN IP)
+curl -s -X POST http://localhost:8000/setup/devices \
+  -H 'Content-Type: application/json' \
+  -d '{"ip": "192.168.x.y"}'
+
+# Confirm it's registered
+curl -s http://localhost:8000/setup/devices | python3 -m json.tool
+```
+
+Note the `device_id` from the response — you need it for migration.
+
+```bash
+# List all known devices and their IDs
+curl -s http://localhost:8000/setup/devices | python3 -m json.tool
+
+# Extract device_id for the speaker by matching its IP
+DEVICE_ID=$(curl -s http://localhost:8000/setup/devices \
+  | python3 -c "import sys,json; devs=json.load(sys.stdin); \
+    [print(d['device_id']) for d in devs if '35' in d.get('ip_address','')]")
+echo "Device ID: ${DEVICE_ID}"
+```
+
+---
+
+## Step 4 — Migrate the Speaker
+
+The migration modifies `SoundTouchSdkPrivateCfg.xml` on the speaker via SSH,
+redirecting `margeServerUrl` (and optionally other service URLs) to the local
+service.
+
+### 4.1 Review the Migration Plan
+
+```bash
+# Dry-run: see what will be changed
+curl -s "http://localhost:8000/setup/summary/${DEVICE_ID}" | python3 -m json.tool
+```
+
+Key fields to check:
+- `margeServerUrl` — should become `http://<MAC_IP>:8000/streaming`
+- `remoteServicesEnabled` — must be `true` for the speaker to make cloud calls
+- `is_migrated` — `false` before, `true` after
+
+### 4.2 Run Migration
+
+```bash
+MAC_IP=$(ipconfig getifaddr en0)
+TARGET_URL="http://${MAC_IP}:8000"
+
+curl -s -X POST \
+  "http://localhost:8000/setup/migrate/${DEVICE_ID}" \
+  -G --data-urlencode "target_url=${TARGET_URL}" \
+  | python3 -m json.tool
+```
+
+Expected response: `{"ok": true, "message": "Migration started", "output": "..."}`.
+The output field contains the SSH transcript of the changes made.
+
+### 4.3 Reboot the Speaker
+
+A reboot applies the new config:
+
+```bash
+curl -s -X POST "http://localhost:8000/setup/reboot/${DEVICE_ID}"
+```
+
+Wait ~30 s for the speaker to come back online. Verify it's back:
+
+```bash
+dns-sd -B _soundtouch._tcp local 2>&1 | grep Add
+# or
+curl -s http://192.168.x.y:8090/info | head -5
+```
+
+### 4.4 Verify Migration
+
+```bash
+# Check migration summary again — is_migrated should now be true
+curl -s "http://localhost:8000/setup/summary/${DEVICE_ID}" \
+  | python3 -c "import sys,json; s=json.load(sys.stdin); print('migrated:', s.get('is_migrated'))"
+```
+
+You should also see incoming connections from the speaker in the service logs once
+it resumes normal operation.
+
+---
+
+## Step 5 — Operate the Bose App
+
+With the speaker migrated and Frida running, every app action triggers traffic
+through the service:
+
+1. **Sign in** — `POST /streaming/account/login`
+2. **Speaker shows as linked** — speaker has called the service to register/sync
+3. **Play music** — BMX registry lookup, playback control
+4. **Set presets** — `POST /streaming/account/{id}/device/{id}/presets/{n}`
+5. **Adjust volume, switch source** — direct speaker API (port 8090, not cloud)
+6. **Check "Now Playing"** — speaker WebSocket events + marge sync
+
+For each action, both mitmweb and the service's recorder capture the request.
+
+---
+
+## Step 6 — Inspect Captured Interactions
+
+### 6.1 Service Interaction Recorder
+
+The service records all incoming requests to `data/interactions/` (configurable via
+`--data-dir`). Browse them via:
+
+```bash
+# List recorded sessions
+curl -s http://localhost:8000/setup/interactions | python3 -m json.tool
+
+# Download a session as HAR
+curl -s "http://localhost:8000/setup/interactions/sessions/<session>/download" \
+  -o session.har
+
+# Find 404/500 responses (unimplemented endpoints)
+curl -s "http://localhost:8000/setup/interaction-content" \
+  | python3 -c "
+import sys, json
+for entry in json.load(sys.stdin).get('entries', []):
+    status = entry.get('response', {}).get('status', 0)
+    if status >= 400:
+        print(status, entry.get('request', {}).get('method'), entry.get('request', {}).get('url'))
+"
+```
+
+### 6.2 mitmproxy Recording
+
+```bash
+# Inspect app→service traffic offline
+CAPTURE="scripts/android/captures/<filename>.mitm"
+mitmweb -r "${CAPTURE}"
+
+# Filter to local service only
+mitmdump -r "${CAPTURE}" \
+  --flow-filter "~u ${MAC_IP}:8000" \
+  2>/dev/null | grep -E "POST|GET"
+
+# Convert to .http files (IntelliJ-compatible, organized by path)
+NAME=$(basename "${CAPTURE}" .mitm)
+OUT="scripts/android/mitm/${NAME}"
+
+/Applications/mitmproxy.app/Contents/MacOS/mitmdump \
+  -n -r "${CAPTURE}" \
+  -s scripts/convert_mitm_script.py \
+  --set out_dir="${OUT}"
+# Output → scripts/android/mitm/<name>/mirror/
+```
+
+### 6.3 Identify Unimplemented Endpoints
+
+Endpoints the service doesn't handle return `404 Not Found`. Check:
+
+```bash
+# From service stats
+curl -s http://localhost:8000/setup/interaction-stats | python3 -m json.tool
+
+# List parity mismatches (local vs upstream divergence, if mirror enabled)
+curl -s http://localhost:8000/setup/parity-mismatches | python3 -m json.tool
+```
+
+---
+
+## Step 7 — Revert Migration (Optional)
+
+To restore the speaker to its original config (pointing back to Bose cloud):
+
+```bash
+curl -s -X POST "http://localhost:8000/setup/revert/${DEVICE_ID}" | python3 -m json.tool
+```
+
+Then reboot the speaker:
+
+```bash
+curl -s -X POST "http://localhost:8000/setup/reboot/${DEVICE_ID}"
+```
+
+---
+
+## Cleanup
+
+```bash
+# Stop mitmweb (Ctrl-C in its terminal)
+# Stop Frida (Ctrl-C in its terminal)
+# Stop soundtouch-service (Ctrl-C in its terminal)
+
+# Remove emulator proxy (if not running another session)
+adb -s emulator-5554 shell settings delete global http_proxy
+```
+

+
+### Navigation Flow
+
+1. **Tab 1 — Settings**: entered all settings above, clicked **Save Settings**, restarted service
+2. **Tab 2 — Devices**: speaker appeared via mDNS discovery; clicked **Sync Data**
+3. **Tab 3 — Data Sync**: clicked **Start Sync** to pull account/device data from Bose cloud
+4. **Tab 2 — Devices**: clicked **Migrate** on the speaker entry
+5. In the Migrate panel: selected **Migration Method → `/etc/resolv.conf`**
+6. Ran pre-migration checks (see below)
+7. Ran migration steps (see below)
+8. Rebooted speaker
+9. Paired and configured speaker via the Bose app
+
+### Pre-Migration Checks
+
+All tests run from the **Devices → Migrate** panel after selecting the speaker (`192.168.x.y`, SoundTouch 10):
+
+- **HTTPS test (explicit CA.crt)**: ✅ passed (result not recorded in detail)
+- **HTTPS test (shared trust store)**: ✅ passed
+  - Speaker connected to `soundtouch.local:443` → `192.168.x.z`
+  - TLS: TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256, cert issued by `SoundTouch Local Root CA`
+  - CA already in speaker's system trust store (`/etc/pki/tls/certs/ca-bundle.crt`)
+- **Preliminary DNS Test**: ✅ passed
+  - Raw DNS query for `aftertouch.test` returned `192.168.x.z` via the service DNS at `192.168.x.z:53`
+- **Planned `/etc/resolv.conf`**:
+  ```
+  # Created by Aftertouch/SoundTouch-Service
+  # Priority nameserver for Bose service redirection
+  nameserver 192.168.x.z
+  ```
+
+### Migration Steps
+
+1. **Enable Persistent Remote Services** → `Successfully ensured remote services for SoundTouch 10 (192.168.x.y)`
+   - Note: `touch /etc/remote_services (with rw): sh: rw: command not found` — safe to ignore, `touch` succeeded
+2. Reloaded migration view by deselecting and reselecting the speaker in the dropdown
+3. **Backup Config Now** → `✅ Found .original config at /opt/Bose/etc/SoundTouchSdkPrivateCfg.xml.original`
+4. **Confirm Migration** → `Successfully started migration for SoundTouch 10 (192.168.x.y). Please reboot the device to activate the changes.`
+
+   Command output:
+   - Off-device backup created ✅
+   - Write access verified ✅
+   - `soundtouch.local` resolved to `192.168.x.z` ✅
+   - `/mnt/nv/soundtouch-service/aftertouch.resolv.conf` uploaded ✅
+   - `rc.local` already contains Aftertouch hook logic ✅
+   - `(rw || mount -o remount,rw /): sh: rw: command not found` — safe to ignore (same shell quirk as above)
+   - `/etc/udhcpc.d/50default` patched and verified ✅
+   - `/opt/Bose/udhcpc.script` patched and verified ✅
+   - CA certificate already trusted, skipping injection ✅
+
+5. **Reboot Speaker** → speaker came back online after ~30 s
+
+### Post-Migration
+
+- Paired speaker to Bose account via app — succeeded ✅
+- Set presets via app — worked ✅
+- Mirroring active and functional during session ✅
+- No visible errors in app behaviour; service logs and interaction recordings not yet reviewed in detail
+
+### Known Shell Warning (safe to ignore)
+
+Two commands produced `sh: rw: command not found`. This occurs because the service wraps commands with `(rw || ...)` as a fallback pattern, but the shell on the ST10 interprets `rw` as a bare command rather than a shell variable/flag. The primary command (`touch`, `mount`) still succeeds. This is a known cosmetic issue in the migration output.

+## 6. AP Mode Wi-Fi Provisioning via Console
+
+When BLE is unavailable (e.g. when using an Android emulator), use AP mode to push Wi-Fi credentials from the Mac command line.
+
+### 6.1 Connect Mac to Speaker AP
+
+After factory reset the speaker broadcasts an SSID like `Bose SoundTouch XXXX`. Connect the Mac to it:
+
+```bash
+# List nearby SSIDs — use System Settings → Wi-Fi (the airport command was removed in macOS Sequoia+)
+# Connect (replace with actual SSID)
+networksetup -setairportnetwork en0 "Bose SoundTouch XXXX"
+```
+
+The speaker's web UI gateway is at `192.0.2.1` (verified: ST10 assigns `192.0.2.2` to the client via DHCP).
+
+```bash
+# Confirm reachability
+curl -sv http://192.0.2.1/ 2>&1 | head -40
+```
+
+### 6.2 Trigger Wi-Fi Site Survey (Optional)
+
+The setup web UI at `http://192.0.2.1/` uses the SoundTouch API on **port 8090** — the same API as normal device operation. Trigger a network scan first so the speaker finds your SSID:

-# HTTPS Setup & Custom CA Certificate
+# HTTPS & Custom CA Certificate

-To use the `/etc/hosts` redirection method safely, SoundTouch devices must communicate over HTTPS. This requires the device to trust the AfterTouch Root CA certificate used by the local service.
+SoundTouch speakers communicate with cloud services over HTTPS. For the local service to work over HTTPS, speakers must trust the AfterTouch Root CA. The service manages this automatically — it generates a CA on first start and the web UI guides you through installing it on each speaker as part of the migration flow.

-## 1. Automated Migration (Hosts Method)
+> ### ⚠️ Speakers connect to `:443`, AfterTouch defaults to `:8443`
+>
+> Speakers build their target URLs from Bose hostnames *without* an explicit port, so they connect on the default HTTPS port **443**. AfterTouch's built-in HTTPS listener defaults to **8443** because port 443 is privileged on most Unix systems.
+>
+> **If you do nothing, speakers will fail with `Curl 7` / connection refused and nothing will appear in the AfterTouch HTTP log.**
+>
+> Pick one of the three options under [Binding to port 443](#binding-to-port-443) below. The settings page in the web UI shows a ✅ / ❌ indicator for `:443` reachability so you can confirm the routing is in place.

-The `soundtouch-service` can automatically configure a device to use the `/etc/hosts` method:
+---

-```bash
-curl -X POST "http://localhost:8000/setup/migrate/{deviceIP}?method=hosts"
+## How TLS works in AfterTouch
+
+The service includes a built-in HTTPS listener (default port `8443`) that presents a certificate covering all Bose cloud hostnames. The certificate is signed by the AfterTouch Root CA, which is generated automatically on first start and stored in `data/certs/`.
+
+**Domain coverage** — the certificate covers:
+- Wildcard: `*.api.bose.io`, `*.api.bosecm.com`
+- Specific: `streaming.bose.com`, `bmx.bose.com`, `stats.bose.com`, `updates.bose.com`, `worldwide.bose.com`, `bose-prod.apigee.net`, `media.bose.io`, `downloads.bose.com`, `voice.api.bose.io`, and more
+
+> **Note**: The hostname you configure as `HTTPS_SERVER_URL` (e.g. `https://soundtouch.fritz.box:8443`) is also added as a Subject Alternative Name, ensuring valid TLS for direct browser or API access.
+
+---
+
+## CA trust installation (via web UI)
+
+The migration flow in the web UI includes a CA trust step that:
+1. Uploads the Root CA to the speaker via SSH
+2. Appends it to the speaker's shared trust store (`/etc/pki/tls/certs/ca-bundle.crt`)
+3. Verifies connectivity over HTTPS
+
+This is handled automatically — you don't need to manage CA files manually unless you're doing an advanced or manual setup.
+
+---
+
+## Downloading the CA certificate
+
+You can download the Root CA for manual installation on other devices (phones, PCs, additional speakers):
+
+```
+http://<server>:8000/setup/ca.crt
 ```

-This command will:
-1.  Connect to the device via SSH.
-2.  Update `/etc/hosts` to point Bose domains to the service IP.
-3.  Inject the auto-generated AfterTouch Root CA into the device's trust store (`/etc/pki/tls/certs/ca-bundle.crt`).
-4.  Reboot the device.
+---

-## 2. Managing the Root CA
+## Binding to port 443

-The AfterTouch service automatically generates a Root CA when it first starts.
+Speakers expect HTTPS on the default port 443. Since binding to port 443 requires elevated privileges, you have three options:

- **CA Certificate**: `data/certs/ca.crt`
- **CA Private Key**: `data/certs/ca.key`
+1. **Port forwarding (recommended)**: Run the service on port 8443 and forward port 443 to it using `iptables` or your firewall/router. Inside an LXC/Docker container or on the host:

-### Downloading the CA Certificate
-You can download the CA certificate for manual installation on other devices (like your phone or PC) from:
-`http://<server-ip>:8000/setup/ca.crt`
+    ```bash
+    iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8443
+    iptables -t nat -A OUTPUT     -p tcp --dport 443 -j REDIRECT --to-port 8443
+    ```

-### 3. Built-in HTTPS Support
+    The first rule covers traffic arriving from speakers; the second covers loopback connections from the host itself (useful for the in-built pre-flight probe).

-The `soundtouch-service` now includes a built-in HTTPS listener. This simplifies the `/etc/hosts` redirection method by automatically presenting the correct certificates for Bose domains.
+2. **Capabilities**: Grant the binary permission to bind low ports and start the listener directly on `:443`:

- **HTTPS Port**: Configurable via `HTTPS_PORT` environment variable (defaults to `8443`).
- **HTTPS Server URL**: Configurable via `HTTPS_SERVER_URL` (e.g., `https://mysoundtouch.local:8443`). If not set, the service attempts to guess it using the system hostname.
- **Domain Coverage**: Automatically presents a certificate with comprehensive coverage using wildcard certificates (`*.api.bose.io`, `*.api.bosecm.com`) plus specific domains (`streaming.bose.com`, `updates.bose.com`, `stats.bose.com`, `bmx.bose.com`, `worldwide.bose.com`, `bose-prod.apigee.net`, etc.).
- **Wildcard Support**: Uses RFC-compliant wildcard certificates for automatic coverage of all API subdomains, including event analytics endpoints like `events.api.bosecm.com`, `eventsdev.api.bosecm.com`, and future API services.
- **TLS Error Logging**: Comprehensive logging of TLS handshake attempts, certificate matching, and connection failures for debugging DNS redirection issues.
- **Automatic Setup**: On first start, it generates a server certificate signed by your AfterTouch local Root CA.
+    ```bash
+    sudo setcap 'cap_net_bind_service=+ep' ./soundtouch-service
+    ./soundtouch-service --https-port=443
+    ```

-#### TLS Security & Debugging
+3. **Reverse proxy**: Use Nginx or Caddy on `:443` in front of the service (see below).

-The built-in HTTPS listener is configured to use modern and secure TLS settings while maintaining compatibility with SoundTouch devices (which support up to TLS 1.2 with OpenSSL 1.0.2).
+### Confirming `:443` is reachable

- **Minimum TLS Version**: TLS 1.2
- **Preferred Cipher Suites**:
-  - `ECDHE-RSA-AES128-GCM-SHA256`
- **TLS Debugging**: Detailed logging of:
-  - Certificate requests by domain (`[TLS] Certificate request for ServerName: events.api.bosecm.com`)
-  - Wildcard certificate matching (`[TLS] ✅ Serving certificate for events.api.bosecm.com (matched *.api.bosecm.com)`)
-  - Handshake failures (`[TLS] ❌ Handshake failed from 192.168.1.50: tls: certificate not found`)
-  - Successful connections (`[TLS] ✅ Successful connection from 192.168.1.50`)
-  - `ECDHE-RSA-AES256-GCM-SHA384`
-  - `ECDHE-RSA-CHACHA20-POLY1305`
-  - `RSA-AES128-GCM-SHA256` (Legacy support)
-  - `RSA-AES256-GCM-SHA384` (Legacy support)
+After applying any of the options above, open the AfterTouch web UI → **Settings**. The Target Domain row will show a second line:

-#### Binding to Port 443
-SoundTouch devices expect HTTPS on the default port 443. Since binding to port 443 usually requires root privileges, you have two options:
+* ✅ `:443 reachable on localhost and <IP> (forwarded to :8443)` — you're good.
+* ❌ `Speakers connect to :443 but AfterTouch listens on :8443.` — the routing is missing or not yet active.

-1.  **Port Forwarding (Recommended)**: Run the service on a high port (e.g., 8443) and use `iptables` or your firewall to forward traffic from 443 to 8443.
-2.  **Capabilities**: Grant the binary permission to bind to low ports: `sudo setcap 'cap_net_bind_service=+ep' ./soundtouch-service`.
-3.  **Reverse Proxy**: Use Nginx or Caddy as described below.
+A third line follows from the browser itself, which sits on the LAN exactly where the speakers do. The browser can't distinguish an untrusted-CA TLS error from a connection refusal, so it uses timing as a heuristic: a fast error means "no listener / firewall reset", a slower one means "something answered TCP". When the server-side and browser-side checks disagree, the UI flags it — that almost always means NAT, split-horizon DNS, or a host firewall sitting between AfterTouch and the LAN.

-### 4. Reverse Proxy (Optional)
+The same check runs once at service startup and prints a `[WARN]` log line if `:443` is unreachable, with the exact iptables/setcap commands for your current listener port.

-1.  **Generate a certificate** for the Bose domains signed by your Root CA.
-2.  **Configure Nginx** to use this certificate and proxy requests to `soundtouch-service`.
+#### When this check is shown
+
+The `:443` indicator is only displayed when **AfterTouch's DNS interception is enabled** (Settings → "Enable DNS Discovery Server"). The check is only meaningful for the **DNS migration method**, where speakers reach AfterTouch via intercepted Bose hostnames and therefore on the implicit `:443`. The other migration method — writing direct `https://<host>:8443/...` URLs into the speaker's private config via SSH — uses the port that's literally in the URL, so `:443` is irrelevant and the check would only add noise.
+
+If you intercept Bose hostnames **outside** AfterTouch (Pi-hole, router DNS rule, `/etc/hosts` on a gateway), the UI gate above will hide the indicator. The data is still in the `GET /setup/settings` JSON response (`https_443_localhost_reachable`, `https_443_lan_reachable`, `https_443_lan_host`) if you want to inspect it directly, or you can briefly enable AfterTouch's DNS server to see the indicator render.
+
+---
+
+## Reverse proxy (optional)
+
+If you prefer to use Nginx or another proxy for TLS termination:

 ```nginx
 server {
    listen 443 ssl;
    server_name streaming.bose.com bmx.bose.com stats.bose.com updates.bose.com;

-    ```
+## Manual CA injection (advanced)

-    ## 6. Verifying Connectivity
+If you need to inject the CA manually (e.g. without the web UI migration flow):

-    You can verify that your device can correctly reach the `soundtouch-service` over HTTPS using the management web UI.
+```bash
+# Copy the CA to the speaker
+scp data/certs/ca.crt root@<SPEAKER-IP>:/tmp/

-    In the **Migration Summary** for a device, you will find an **HTTPS Connection Test** section:
-    - **Test with Explicit CA.crt**: Uploads a temporary copy of the Root CA to the device and uses `curl --cacert` to verify the connection. Use this to verify your HTTPS setup *before* modifying the device's shared trust store.
-    - **Test with Shared Trust Store**: Uses the device's default trust store. Use this to verify that your CA injection was successful and the device now natively trusts your local server.
+# Make the filesystem writable and append the CA to the trust store

-# Complete Migration Guide - From Bose Cloud to Local SoundTouch Service
+## What you need

-## Overview
+- A machine that is **always on** (Raspberry Pi, NAS, home server, or similar) to run the service
+- A **USB drive** (FAT-formatted) to enable SSH on each speaker
+- Your speakers must be on the **same network** as the service host
+- About **15–30 minutes per speaker**

-This guide will walk you through migrating your Bose SoundTouch speakers from Bose's cloud services to AfterTouch, your own local SoundTouch service. By the end of this process, your speakers will be completely independent of Bose's servers while retaining all their functionality.
+---

-> **💡 Why Migrate?** Bose announced the shutdown of their SoundTouch cloud services in May 2026. This migration ensures your speakers continue working indefinitely with enhanced local control and monitoring.
+## Step 1: Install and start the service

-## What You'll Need
+Choose the option that fits your setup.

-### Hardware Requirements
- **Raspberry Pi 4 or similar** (minimum: Raspberry Pi Zero 2W)
- **MicroSD card** (16GB or larger)
- **USB drive** (for device preparation)
- **Network connection** for your Raspberry Pi
-
-### Before You Start
- **List all your SoundTouch devices** and their current locations
- **Note your current presets and favorites** (they will be preserved)
- **Ensure devices are on the same network** as your future SoundTouch service
- **Basic computer skills** (following instructions, using a web browser)
-
-### Time Estimate
- **Setup**: 30-60 minutes for the service installation
- **Per Device**: 10-15 minutes for each speaker migration
- **Total**: 1-3 hours depending on number of devices
-
-## Step 1: Install SoundTouch Service
-
-### Option A: Raspberry Pi Installation (Recommended)
-
-#### 1.1 Prepare Your Raspberry Pi
-
-1. **Flash Raspberry Pi OS** to your SD card using Raspberry Pi Imager (see the raspberrypi.com documentation)
-2. **Enable SSH** during imaging or create an empty `ssh` file on the boot partition
-3. **Boot your Pi** and connect it to your network
-4. **Find your Pi's IP address** (check your router or use `ping raspberrypi.local`)
-
-#### 1.2 Install SoundTouch Service
-
-Connect to your Pi via SSH and run:
+### Binary (go install)

 ```bash
-# Download and install
-curl -sSL https://github.com/gesellix/Bose-SoundTouch/releases/latest/download/install.sh | bash
-
-# Start the service
-sudo systemctl enable soundtouch-service
-sudo systemctl start soundtouch-service
+go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-service@latest
+soundtouch-service
 ```

-#### 1.3 Verify Installation
+The service starts on port 8000. Open `http://localhost:8000` in your browser.

-1. Open your web browser
-2. Go to `http://[PI_IP_ADDRESS]:8000` (replace with your Pi's IP)
-3. You should see the **SoundTouch Service Dashboard**
+### Docker Compose (recommended for home servers and VMs)

-![SoundTouch Service Dashboard](../images/dashboard-home.png)
-*Example: SoundTouch Service main dashboard*
+The repository ships a `docker-compose.yml` ready for this use case. Clone or download it, copy the example config, then edit `.env` before starting:

-### Option B: Docker Installation
+```bash
+cp .env.example .env
+# Edit .env:
+#   SOUNDTOUCH_HOSTNAME=192.168.1.100   ← your server's address
+#   SOUNDTOUCH_VERSION=v0.70.0          ← pin to a release tag instead of 'latest'
+docker compose up -d
+```

-If you prefer Docker, run:
+`SOUNDTOUCH_HOSTNAME` is the address your speakers will use to reach the service — use a hostname or IP reachable from the speaker, not `localhost`.
+
+On **Linux** (Debian, Proxmox VE, Raspberry Pi OS, etc.) you can enable host networking for automatic speaker discovery. Uncomment the `network_mode: host` line in `docker-compose.yml` and remove the `ports:` section (they conflict with host networking). Without host networking, add your speakers by IP address in Step 4 instead.
+
+For local overrides (e.g. switching to `build: .` during development), create a `docker-compose.override.yml` — Docker Compose picks it up automatically and it is not tracked in version control.
+
+> **Note on `docker-compose.ci.yml`**: this file contains mock services used only for automated integration tests. It is not needed for your own deployment.
+
+### Docker run (Linux — with host networking for device discovery)

 ```bash
 docker run -d \
  --name soundtouch-service \
-  --restart unless-stopped \
-  -p 8000:8000 \
-  -p 8443:8443 \
-  -v soundtouch-data:/data \
-  gesellix/soundtouch-service:latest
+  --network host \
+  -v $(pwd)/data:/app/data \
+  ghcr.io/gesellix/bose-soundtouch:latest
 ```

-## Step 2: Create Your Account
+### Docker run (macOS / Windows — manual device IP required)

-### 2.1 Initial Setup
-
-1. **Open the dashboard** at `http://[SERVICE_IP]:8000`
-2. Click **"Create New Account"**
-3. **Fill in your details**:
-   - Account Name: `My Home Audio`
-   - Email: `your@email.com` (optional, for notifications)
-   - Migration Strategy: `Gradual` (recommended)
-
-![Account Creation](../images/account-creation.png)
-*Example: Account creation form*
-
-### 2.2 Account Configuration
-
-After creation, you'll see your **Account Dashboard**:
- **Account ID**: Unique identifier (e.g., `acc_home_audio_001`)
- **Status**: `Active - Ready for Migration`
- **Device Count**: Initially 0
- **Migration Status**: `Prepared`
-
-![Account Dashboard](../images/account-dashboard.png)
-*Example: Fresh account dashboard ready for device migration*
-
-### 2.3 Initial Settings
-
-Once your account is created, configure the global settings:
-1. **Settings**:
-   - Check **Target Domain**: Ensure it's reachable from the speaker (e.g., `soundtouch.fritz.box`).
-   - **DNS Discovery**: Enable DNS discovery on port `:53`. This is crucial for the DNS hook migration method.
-2. **Devices**:
-   - Go to the **"Device Discovery"** tab.
-   - Click **"Scan Network"** or manually add a speaker via IP address.
-   - Your devices should appear with **SSH Status**: `Enabled`.
-
-![Device Discovery](../images/device-discovery.png)
-*Example: Discovered devices with remote access enabled*
-
-## Step 3: Prepare Your Devices
-
-> **⚠️ Important**: This step temporarily enables SSH access on your speakers. SSH will be automatically disabled after migration unless you choose to keep it enabled.
-
-### 3.1 Enable Remote Services
-
-For each SoundTouch device:
-
-1. **Prepare a USB drive**:
-   - Format as FAT32
-   - Create an empty file named `remote_services` (no extension)
-   - (Optional) Firmware update/reset, see [Bose SoundTouch USB Update](https://downloads.bose.com/ced/soundtouch/soundtouch_usb/index.html)
-
-2. **Insert USB drive** into your SoundTouch speaker
-3. **Power cycle** the device (unplug for 10 seconds, then reconnect)
-
-![USB Preparation](../images/usb-remote-services.png)
-*Example: USB drive setup for enabling remote services*
-
-## Step 4: Discover and Register Devices
-
-### 4.1 Automatic Discovery
-
-The service automatically scans for SoundTouch devices every 5 minutes. To trigger immediate discovery:
-
-1. **Dashboard** → **"Devices"** → **"Discover Devices"**
-2. **Wait 30-60 seconds** for scan completion
-3. **Review discovered devices** in the list
-
-### 4.2 Register Devices to Your Account
-
-For each discovered device:
-
-1. **Click device name** in the discovery list
-2. **Verify device information**:
-   - Name: `Living Room Speaker`
-   - Model: `SoundTouch 30`
-   - MAC Address: `A8:1B:6A:53:6A:98`
-   - IP Address: `192.168.1.100`
-   - Status: `Discovered - Ready for Registration`
-
-3. **Click "Register to Account"**
-4. **Choose registration type**:
-   - **Fresh Setup**: For new or factory-reset devices
-   - **Migrate from Bose**: For devices with existing Bose account (recommended)
-
-![Device Registration](../images/device-registration.png)
-*Example: Device registration dialog with migration options*
-
-### 4.3 Device Registration Results
-
-After registration, you'll see:
- **Device Status**: `Registered - Active`
- **Account Association**: Your account name
- **Lifecycle State**: `Active`
- **Data Sources**: `Mirror Primary` (initially uses Bose, falls back to local)
-
-## Step 5: Migrate Individual Devices
-
-### 5.1 Step 3: Data Sync
-
-1. **Dashboard** → **"Devices"** → Select your device
-2. Click **"Data Sync"**
-3. This fetches configuration (presets, recents, sources) from the speaker to the SoundTouch service.
-
-### 5.2 Step 4: Migration
-
-Once data is synced, proceed to the migration tab for the device:
-
-1. **Backup XML**: Create an off-device backup of the current configuration.
-2. **Enable Persistent Remote Service**: This ensures SSH remains available after reboots.
-   - *Note*: If you see `'rw: command not found'`, you can safely ignore it.
-3. **CA Certificate Configuration**:
-   - **Test with explicit CA**: Verify the speaker can communicate using the local CA.
-   - **Trust CA now**: Inject the local Root CA into the speaker's trust store.
-   - **Test with shared trust store**: Verify general HTTPS communication.
-4. **Migration Method**:
-   - Select **"Redirect via DNS hook"**.
-   - **Test DNS Redirection**: Ensure the speaker correctly resolves the service domain.
-5. **Confirm Migration**: Apply the final changes to the speaker.
-

-## Step 7: Complete Account Migration
+On macOS/Windows, device discovery via mDNS won't work inside the container — you'll add devices by IP address in Step 4.

-### 7.1 Migrate All Devices
-
-Repeat the migration process for each of your SoundTouch devices. You can migrate multiple devices simultaneously, but we recommend doing 1-2 at a time to monitor progress.
-
-**Migration Dashboard** shows overall progress:
- **Devices Migrated**: `2 of 4 completed`
- **Currently Migrating**: `Living Room Speaker, Kitchen Speaker`
- **Pending Migration**: `Bedroom Speaker, Office Speaker`
- **Estimated Completion**: `3 days remaining`
-
-![Account Migration Status](../images/account-migration.png)
-*Example: Account-wide migration progress*
-
-### 7.2 Verify Complete Migration
-
-When all devices are migrated:
-
-1. **Account Status**: `Active - Fully Migrated`
-2. **Bose Dependency**: `None`
-3. **Local Control**: `100%`
-4. **Device Health**: All devices show `Healthy - Local Only`
-
-![Migration Complete](../images/migration-complete.png)
-*Example: Completed migration dashboard*
-
-## Step 8: Post-Migration Tasks
-
-1. **Remove USB stick** from the speaker.
-2. **Reboot** the device to apply all changes.
-
-### 8.1 Disable Remote Services (Optional)
-
-For enhanced security, you can disable SSH on migrated devices. However, keeping it enabled allows for easier future maintenance or reverts.
-
-### 8.2 Configure Backups
-
-Set up automatic backups of your device configurations:
-
-1. **Dashboard** → **"Settings"** → **"Backup"**
-2. **Enable Automatic Backups**: ✅
-3. **Backup Schedule**: `Daily at 2 AM`
-4. **Retention**: `Keep 30 days`
-5. **Export Location**: `/data/backups` or external storage
-
-![Backup Configuration](../images/backup-setup.png)
-*Example: Backup configuration settings*
-
-### 8.3 Set Up Monitoring Alerts (Optional)
-
-Configure notifications for important events:
-
-1. **Dashboard** → **"Settings"** → **"Notifications"**
-2. **Email Notifications**: Enter your email
-3. **Alert Types**:
-   - ✅ Device goes offline
-   - ✅ Migration failures
-   - ✅ Service errors
-   - ✅ Daily health summary
-
-## Troubleshooting Common Issues
-
-### Device Not Discovered
-
-**Problem**: Device doesn't appear in discovery scan
-
-**Solutions**:
-1. **Check network**: Ensure device and service are on same network
-2. **Verify USB setup**: Confirm `remote_services` file was processed
-3. **Power cycle**: Unplug device for 30 seconds, reconnect
-4. **Manual add**: Dashboard → "Devices" → "Add Manually" with IP address
-
-### Migration Stuck

-2. **Review logs**: Dashboard → Device → "View Logs"
-3. **Restart migration**: Device → "Migration" → "Restart Process"
-4. **Rollback**: Device → "Migration" → "Rollback to Bose"
-
-### Presets Not Working
-
-**Problem**: Saved presets don't work after migration
-
-**Solutions**:
-1. **Verify sources**: Check configured sources are still available
-2. **Re-authenticate**: Re-login to music services (Spotify, etc.)
-3. **Rebuild presets**: Dashboard → Device → "Presets" → "Rebuild from Backup"
-
-### Service Unreachable
-
-**Problem**: Cannot access SoundTouch Service dashboard
-
-**Solutions**:

-## Summary
+## Step 2: Configure the service URL

-Congratulations! 🎉 You've successfully migrated your SoundTouch speakers to local control. Your devices are now:
+Open `http://<server>:8000` and go to the **Settings** tab.

- ✅ **Independent** of Bose cloud services
- ✅ **Fully functional** with all original features preserved
- ✅ **Enhanced** with better monitoring and control
- ✅ **Future-proof** against service shutdowns
+![AfterTouch Settings tab](../images/ui-settings.png)

-**What's Next?**
+Set the **Target Domain** to the address your speakers can reach — for example `https://soundtouch.fritz.box` or `http://192.168.1.100:8000`. This must be the host's address on your local network, not `localhost`.

- **Enjoy your music** with enhanced local control
- **Monitor your system** through the dashboard
- **Share your experience** with the community
- **Explore advanced features** as you become more comfortable
+If you plan to use DNS/DHCP redirect, enable the **DNS Discovery Server** and set the **DNS Bind Address** to `:53`. The upstream DNS should be your router's IP, not the service's own address.

-Your SoundTouch speakers will now continue working indefinitely, regardless of external service availability. Welcome to true audio independence! 🔊
+> **Tip**: If you change settings and they don't seem to take effect, check `data/settings.json` — settings saved in the UI take precedence over environment variables.
+
+---
+
+## Step 3: Enable shell access on each speaker
+
+The wizard supports **two transports** for talking to the speaker. Pick whichever your device exposes:
+
+### SSH (recommended — required for XML migration, DNS interception, and CA install)
+
+The XML migration writes updated configuration to the speaker's filesystem, which requires SSH access. Enable it once per device:
+
+1. Format a USB drive as FAT (FAT32). Some speakers require the **bootable flag** to be set on the partition — see [SoundCork issue #172](https://github.com/deborahgu/soundcork/issues/172) for details.
+2. Create an empty file named **`remote_services`** (no extension) in the root of the drive.
+3. Insert the drive into the speaker's USB port while it is powered on.
+4. Power-cycle the speaker (unplug the power cable, wait 10 seconds, reconnect).
+5. After boot, root SSH is available with no password: `ssh -oHostKeyAlgorithms=+ssh-rsa root@<SPEAKER-IP>`
+
+You only need to do this once per speaker. SSH can remain enabled for future maintenance or be disabled after migration — your choice.
+
+### Telnet:17000 (fallback when SSH isn't possible)
+
+If the USB-stick unlock doesn't work on your speaker (some firmware revisions refuse it — notably SA-5, ST520, and recent ST Portables), the wizard falls back to the speaker's **built-in diagnostic shell on TCP port 17000**. No setup required — most SoundTouch firmware exposes it automatically. The wizard detects which transports are available and picks the right one; you don't have to choose manually.
+
+Telnet-only migrations are limited to HTTP (no CA install possible without SSH). The wizard surfaces this clearly when it applies.
+
+---
+
+## Step 4: Add and sync your speaker
+
+### Discover
+
+The service scans for SoundTouch devices automatically every few minutes. Check the **Devices** tab in the web UI. If your speaker doesn't appear, click **Scan Again** to trigger an immediate scan, or enter the IP address manually and click **Add Device**.
+
+![AfterTouch Devices tab showing discovered speakers](../images/ui-devices.png)
+
+### Sync
+
+Once the speaker appears, click **Sync Data**. This connects to the speaker and pulls its current presets, recently played items, and configured sources into the local service's datastore. It also creates an off-device backup of the speaker's configuration.
+
+![Data Sync tab showing a successful sync](../images/ui-sync.png)
+
+If the Bose cloud is still running, Sync also fetches your account data from Bose's servers. This is your preservation step — do it before the cloud shuts down.
+
+---
+
+## Step 5: Migrate
+
+Click **Migrate** next to a device on the Devices tab to open the Migration tab. The tab opens with a **Migration Summary** that shows where your speaker currently stands, then offers a one-click suggested plan and a fully customizable form underneath.
+
+![Migration tab showing the state card and Plan card](../images/ui-migration.png)
+
+### What you see at the top — the state card
+
+Three rows tell you the speaker's current state at a glance:
+
+- **Transports** — whether SSH and Telnet:17000 are reachable. The wizard's choices are driven by these.
+- **Migration State** — three orthogonal axes:
+  - *URL Configuration* — original Bose URLs or AfterTouch URLs (with a special "intercepted via DNS" verdict when the resolv.conf hook is doing the redirect).
+  - *DNS Interception* — none, or `/etc/resolv.conf` hook active.
+  - *CA / TLS* — local root CA installed on the device, with `Trust CA Now` and `Download CA cert` actions inline.
+- **Preconditions** — `remote_services` persistence, account pairing state, and XML config backup presence.
+
+### The Plan card — the happy path
+
+Below the state card is the **Plan** card. For most users this is the only thing you'll touch:
+
+1. **Target service URL** — pre-filled from your Settings. Edit inline and click *Save as default* to update Settings without bouncing tabs.
+2. **Capabilities** — what transports the speaker exposes and what AfterTouch can offer given those.
+3. **Service URLs** — four URL inputs (margeServerUrl, statsServerUrl, swUpdateUrl, bmxRegistryUrl) pre-filled with canonical defaults. Most users leave them as-is; soundcork users tick the *Soundcork mode* checkbox to append `/marge` to `margeServerUrl`. URL validation runs on every keystroke.
+4. **Account pairing** — pre-filled with the speaker's current account ID. Leave it to keep the existing pairing, change it to re-pair, or click *Generate* to assign a new 7-digit ID on a factory-reset device.
+5. **Suggested plan** — one big green button: *Apply Suggested Plan*. The wizard picks the most conservative recipe for your speaker (XML over SSH with HTTP when SSH works; telnet URL flip with HTTP when only telnet works) and runs it.
+
+### What happens when you click Apply
+
+The wizard switches to a visible **Pre-flight checks** panel and runs every applicable verification before touching the speaker:
+
+- **Backend summary re-check** — confirms transports, hostname resolution, and that the URLs you plan to write match what the backend would produce.
+- **HTTPS connection from device** (SSH-capable speakers) — uploads a temporary CA and runs `curl` from the speaker to your service.
+- **Reachability check (passive observer)** (already-migrated speakers) — nudges `:8090/swUpdateCheck` on the device and watches for *any* request from the speaker to land on the service. Used when the speaker is already migrated and the service is the natural target of its outbounds.
+- **"Round-trip validation runs after Apply + reboot"** (not-yet-migrated speakers) — surfaced as a skip row with a rationale. The speaker's swUpdate daemon caches its URL at boot, so there is no useful no-reboot round-trip check pre-migration; the canonical telnet flow is Apply → reboot → re-run pre-flight on the migrated speaker.
+- **DNS redirection from device** — when DNS interception is part of the plan.
+
+On all-green, the wizard auto-proceeds. On any failure, it pauses with *Proceed Anyway* / *Cancel* buttons so you can override on a known-false-positive (slow DNS, etc.) or fix the underlying issue and retry.
+
+### Customize this migration — for mix-and-match
+
+Expand the `▸ Customize this migration` section to pick any combination of three independent axes:
+
+- **URL flip transport** — XML over SSH / Telnet (Port 17000) / Skip
+- **DNS interception** — None / `/etc/resolv.conf` hook
+- **Local CA install** — checkbox (SSH-only)
+
+Each option carries a per-axis availability hint (e.g. *(SSH unreachable)*, *(already trusted)*) so you see why an option is disabled before you pick. *Apply Custom Plan* runs the chosen combination as a sequence; the same pre-flight panel gates the execution.
+
+> **Note**: DNS interception bundles the CA install on the backend, so a standalone CA-install step is skipped automatically when DNS is part of the plan. The wizard handles this for you.
+
+---
+
+## Step 6: Reboot and verify
+
+After a successful Apply the wizard auto-expands the Customize section and highlights the **Reboot Speaker** button. Click it (or power-cycle the speaker manually) to apply all configuration changes. The reboot transport is picked automatically from your URL flip choice — telnet reboot for SSH-less speakers, SSH reboot otherwise.
+
+After reboot:
+- The speaker should appear as **migrated** in the Devices tab
+- The state card on the Migration tab should now show ✅ for URL Configuration (or "intercepted via DNS" if you used the resolv.conf hook)
+- Presets should load and play (served from the local service)
+- TuneIn browsing should work
+- Recently played items should appear
+
+If something doesn't work, check the **Interactions** tab in the web UI for failed requests, and the **Troubleshooting** section in the [SoundTouch Service Guide](SOUNDTOUCH-SERVICE.md).
+
+---
+
+## Repeat for each speaker
+
+Each speaker is migrated independently. You can run multiple migrations in parallel, but migrating one at a time makes it easier to diagnose issues.
+
+---
+
+## Alternative: CLI-driven factory-reset workflow
+
+If you prefer scripting the migration, or the wizard isn't an option (headless server, automation, batch onboarding of many speakers), `soundtouch-cli` exposes the same building blocks. The flow below is **not** an in-place migration — it factory-resets the speaker and brings it up fresh against AfterTouch, so any data Bose preserved on the device is wiped. Use this when:
+
+- You're starting from a factory-reset speaker anyway.
+- The wizard's in-place migration didn't take and you want a clean slate.
+- You're scripting setup for many speakers and want a reproducible recipe.
+
+### Prerequisites
+
+- AfterTouch service running and reachable at a stable URL (e.g., `https://soundtouch.local` from your `.env`).
+- The speaker reachable on its current IP (passed as `--host`).
+- For the AP-mode handover step, your laptop must be able to join the speaker's `Bose SoundTouch` Wi-Fi (you'll switch between home Wi-Fi and the speaker's AP).
+
+### The full sequence
+
+```bash
+# 1. Plan what the reset+pair pipeline will write (dry run, no changes yet).
+soundtouch-cli --host 192.168.1.50 setup plan \
+  --reset=true --include-pair=false \
+  --service-url='https://soundtouch.local'
+
+# 2. Trigger the factory reset. The speaker reboots into AP mode.
+soundtouch-cli --host 192.168.1.50 setup factory-reset
+
+# --- Manual step: join the speaker's Wi-Fi AP (SSID "Bose SoundTouch ...") ---
+
+# 3. Wait for the AP-mode endpoint to answer.
+soundtouch-cli setup wait-ap
+
+# 4. Push your home Wi-Fi credentials to the speaker.
+#    Run twice if the first attempt's ACK races the AP teardown — the second
+#    one is a no-op if the first succeeded.
+soundtouch-cli setup wifi-push --ssid="YourHomeSSID" --pass='your-wifi-password'
+
+# --- Manual step: switch your laptop back to the home Wi-Fi network ---
+
+# 5. Wait for the speaker to come back online on the home network.
+#    --match takes the last 4-6 hex chars of the speaker's MAC (visible on
+#    the bottom of the device).
+soundtouch-cli setup wait-online --match=42CAFE
+
+# 6. Pair the speaker with an AfterTouch account.
+#    --mode=full runs the canonical WebSocket SETUP sequence (matches the
+#    Bose app's flow); --account is the 7-digit account ID AfterTouch
+#    should attach the speaker to.
+soundtouch-cli --host 192.168.1.50 setup pair \
+  --mode=full --account=1111111 \
+  --service-url='https://soundtouch.local'
+```
+
+### Verifying the result
+
+After pairing completes:
+
+- The speaker should appear on the **Devices** tab in the web UI.
+- AUX should switch and play audio when selected.
+- Pressing presets should fetch their content from AfterTouch (the `[LOG]` rows on the service confirm).
+- TuneIn search and playback should work end-to-end.
+
+If any of these fail post-pair, see [Troubleshooting](TROUBLESHOOTING.md) — most commonly the speaker just needs a power cycle to pick up everything cleanly.
+
+### Differences vs the wizard
+
+| Aspect                              | Wizard (in-place migration)                             | CLI factory-reset workflow                              |
+|-------------------------------------|---------------------------------------------------------|---------------------------------------------------------|
+| Preserves speaker's existing state  | yes (Presets, recents, attached account)                | **no** — wipes everything                               |
+| Requires Wi-Fi-network switching    | no                                                      | yes (laptop joins speaker AP, then home network)        |
+| Scriptable / reproducible           | clickable, not scriptable                               | full bash recipe                                        |
+| Cloud-side data (Bose Marge backup) | preserved if Sync ran while cloud was alive             | not relevant — fresh account on AfterTouch              |
+| Best for                            | "I want this speaker to keep working with what's on it" | "I want a clean, reproducible setup against AfterTouch" |
+
+The wizard is still the recommended path for a one-off migration of an existing setup. The CLI workflow is the right choice when you're scripting, batching, or already starting from a reset.
+
+---
+
+## Rollback
+
+If you need to undo a migration:
+
+- **From the web UI**: Use the **Revert to Defaults** action on the device — this restores the `.original` backup files created on the speaker during the XML migration.
+- **Telnet-only migrations**: the wizard writes both the runtime configuration layer (`sys configuration …`) and the persistent layer (`envswitch boseurls set …`) so the migration survives reboot. If you want to revert quickly, the cleanest path is to re-run the wizard with the original Bose URLs in the URL editor.
+- **Via SSH**: The original XML config is backed up on the speaker with a `.original` suffix. Restore it manually if the UI is unreachable.
+- **Factory reset**: As a last resort, perform a factory reset (see [Device Initial Setup](DEVICE-INITIAL-SETUP.md) for button sequences). This wipes all configuration and returns the speaker to out-of-box state.
+
+---
+
+## Post-migration
+
+Once all speakers are migrated, the `data/` directory is the source of truth for your presets, recents, and device state. Back it up periodically. The web UI at `http://<server>:8000` is your management interface from this point on.
+
+For the Bose cloud backup you created in Step 4, keep the `.tar.gz` archive in case you need to restore credentials or presets later.

+# 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.
+

+> **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.

+
+**Precedence**: `*_url` overrides win over the `marge / stats / sw_update / bmx` mode selectors. The setup package applies `applyProxyOptions` first, then `applyURLOverrides` clobbers any field where a literal `*_url` was supplied. So if you send both `marge=proxied&marge_url=http://x:8000/marge`, the literal `http://x:8000/marge` is written.
+
+**Soundcork redirect**: append `/marge` to `marge_url`. The telnet method derives `envswitch boseurls set <margeServerUrl> <swUpdateUrl>` from the final URLs verbatim, so the suffix propagates to the parallel persistence layer automatically — no separate flag needed.
+
+**Examples**:
+
+```bash
+# Canonical XML migration over SSH to the default service URL
+curl -X POST "http://localhost:8000/setup/migrate/192.168.1.100?method=xml"
+
+# Telnet migration with the soundcork redirect (only marge gets the /marge suffix)
+curl -X POST "http://localhost:8000/setup/migrate/192.168.1.100?method=telnet&target_url=http://soundcork.local:8000&marge_url=http://soundcork.local:8000/marge"
+
+# DNS interception (writes /etc/resolv.conf hook + installs CA) — *_url overrides are ignored
+curl -X POST "http://localhost:8000/setup/migrate/192.168.1.100?method=resolv&target_url=https://my-server.com:8443"
+```
+
+#### `POST /setup/telnet-probe/{deviceIP}`
+SSH-less reachability check. Temporarily flips the speaker's `swUpdateUrl` via the port-17000 diagnostic shell, triggers `:8090/swUpdateCheck` on the device, and observes whether the resulting outbound lands on this service's `/probe/{token}` handler within 6 s. Always attempts to restore the original `swUpdateUrl` even on failure.
+
+**Query Parameters:**
+- `target_url` (optional): defaults to the service's configured `ServerURL`. The probe URL written to the device is `<target_url>/probe/<token>`.
+
+**Response:**
+```json
+{
+  "ok": true,
+  "result": {
+    "reached": true,
+    "restored": true,

+    "elapsed_ms": 412,
+    "logs": "…"
+  }
+}
+```
+
+`reached=true` means the device's outbound landed on our `/probe/{token}` route within the timeout. `restored=true` means the runtime `swUpdateUrl` was reverted to its captured original (the envswitch persistence layer is left untouched throughout, so a reboot heals the device naturally if our restore step fails).

+Catch-all endpoint that signals the matching pre-flight probe channel. Used internally by `/setup/telnet-probe/{deviceIP}`; not intended to be called directly by API consumers. Returns a minimal `<swUpdateIndex/>` XML so the device's `swUpdateCheck` doesn't choke on a missing structure.

-### Bose Cloud Shutdown: Survival Guide for SoundTouch
+# Bose Cloud Shutdown: Survival Guide

-With Bose's announcement of discontinuing cloud support for SoundTouch devices in May 2026, this project provides the necessary tools to keep your speakers fully functional using a local emulation service.
+Bose is shutting down SoundTouch cloud services on **May 6, 2026**. After that date, the following stop working:

-This guide explains how to set up the `soundtouch-service` to run your devices independently of Bose's servers.
+- Music service browsing (TuneIn, Spotify connect via app, etc.)
+- Preset and recently-played sync
+- The official SoundTouch app
+- Software update checks
+
+What **continues to work** regardless:
+- Local playback controls via `soundtouch-cli`, `soundtouch-web`, or any app that uses the local Web API
+- Bluetooth, AUX, and AirPlay inputs
+- Multiroom zones (local, peer-to-peer)
+
+**AfterTouch** — the `soundtouch-service` — restores everything in the first list by running a local replacement for the Bose cloud on your own network.

 ---

-### Supported Use Cases
+## How it works

-1.  **Local Service Emulation**: The service emulates Bose's BMX (Bose Media eXchange) and Marge services, which handle content registries, presets, recents, and software update checks.
-2.  **Traffic Redirection**: Tools are provided to redirect your speakers to this local service instead of `*.bose.com`.
-3.  **Offline Operation**: Once redirected, the speakers function without needing to reach Bose's servers.
-4.  **Preset & Recent Management**: Captures and stores presets and "recently played" items locally.
+The service emulates the Bose cloud endpoints that speakers call for music service browsing, device registration, preset sync, and update checks. Once a speaker is redirected to point at the local service instead of Bose's servers, it operates independently. The built-in web UI at `http://<server>:8000` handles all setup steps.

 ---

-### Setup Steps
+## Prerequisites

-To set up your SoundTouch system for local-only operation, follow these steps:
+### 1. A machine that's always on

-#### 1. Install and Start the Service
-Run the `soundtouch-service` on a machine that is always on (like a Raspberry Pi or a NAS) within your local network.
+The service must run on a host that's available whenever your speakers are in use — a Raspberry Pi, NAS, home server, or similar. The host needs a stable local address (e.g. `soundtouch.fritz.box` or a fixed IP) reachable from your speakers.

-```bash
-# Install the service
-go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-service@latest
+See [Raspberry Pi Setup](RASPBERRY-PI.md) and the [SoundTouch Service Guide](SOUNDTOUCH-SERVICE.md) for deployment options, including Docker.

-# Start the service (defaults to http://localhost:8000)
-soundtouch-service
-```
+### 2. SSH access on your speakers (for migration)

-#### 2. Access the Management UI
-Open your web browser and navigate to the service's web interface:
-`http://<your-server-ip>:8000/`, e.g. `http://localhost:8000/`
+Redirecting a speaker's service URLs requires writing to its configuration. This is done via SSH. Enable it once per device:

-*Note: The service also supports a `/web/` path for management.*
+1. Create a file named `remote_services` on a FAT-formatted USB drive. The drive may need its bootable flag set — see [SoundCork issue #172](https://github.com/deborahgu/soundcork/issues/172) for details.
+2. Insert the drive into the speaker's USB port while it's powered on.
+3. Power-cycle the speaker (unplug and replug). After boot, root SSH is available with no password.

-#### 3. Enable SSH on Your Speakers
-To migrate your speakers, the service needs SSH access. You can enable it by:
-1. Creating an empty file named `remote_services` on a USB stick.
-2. Inserting the USB stick into the SoundTouch speaker's service port.
-3. Rebooting the speaker (unplug/replug).
-
-**Verify SSH Access:**
- Confirm the device responds to SSH without a password: `ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedAlgorithms=+ssh-rsa root@<IP>`
- Or use the **Migration** tab in the Web UI to see if the device shows a "✅ Success" status for SSH.
-Once enabled, you can log in as `root` (no password).
-
-#### 4. Setup Through the Web UI
-The web interface handles the entire process in a guided flow. Before proceeding, we strongly recommend reviewing the [Migration & Safety Guide](MIGRATION-SAFETY.md).
-
-*   **Step 1: Settings**: Configure your server's IP or domain. This ensures the speakers know where to find the local services.
-*   **Step 2: Devices**: The service automatically scans for SoundTouch devices on your network. If a device is not found, you can manually add its IP address.
-*   **Step 3: Data Sync**: Select your device and click "Start Sync". This will automatically fetch your presets, recents, and configured sources from the speaker and store them in the local `data/` directory.
-*   **Step 4: Migration**: Choose your redirection method (XML Recommended) and click "Confirm Migration". After the migration, reboot your speaker to apply the changes.
-
-#### 5. Verify Your Local Data
-Once migrated, your speaker will use the data captured during the Sync step.
-*   The service stores data in the `data/` directory, organized by device serial number (e.g., `data/default/devices/<SERIAL>/`).
-*   **Automatic Capture**: As you use the device (changing presets, playing new music), the service continues to "learn" and update your local files.
+You can leave SSH enabled for future maintenance, or disable it once migration is complete.

 ---

-### Comparison with other implementations (soundcork)
-Our implementation (`soundtouch-service`) is largely compatible with the Python-based `soundcork` project but offers several advantages:
- **Web UI**: Integrated management interface for discovery and migration.
- **Surgical Migration**: Uses XML-based redirection by default, which is less invasive than `/etc/hosts`.
- **Automated SSL**: Handles Root CA injection automatically for secure communication.
- **Proxy Support**: Can proxy requests to original Bose servers while "learning" your configuration.
+## Scenario A: Migrate before the shutdown
+
+Do this while the Bose cloud is still running. Your existing presets and listening history are preserved.
+
+**Step 1 — Back up your data.**
+Run `soundtouch-backup all` to save your Bose account data (presets, paired devices, music sources) and each speaker's local state. See the [soundtouch-backup README](../../cmd/soundtouch-backup/README.md) for usage.
+
+**Step 2 — Start the service and open the web UI** at `http://<server>:8000`.
+
+**Step 3 — Configure the server URL.**
+In the Settings tab, set the server URL to the address your speakers can reach (e.g. `http://soundtouch.fritz.box:8000`). If you plan to use DNS/DHCP redirect, also configure the HTTPS server URL.
+
+**Step 4 — Add your speaker.**
+The service discovers devices on your network automatically. If a speaker doesn't appear, add it manually by IP address.
+
+**Step 5 — Sync device data.**
+Click "Sync" on the device to pull its current presets, recents, and sources from the Bose cloud into the local service's datastore.
+
+**Step 6 — Migrate.**
+The web UI offers two redirect methods and walks you through each step:
+
+| Method       | How it works                                           | When to use                                              |
+|--------------|--------------------------------------------------------|----------------------------------------------------------|
+| XML redirect | Uploads a config file to the speaker via the Web API   | Testing; simpler setup; covers only registered endpoints |
+| DNS/DHCP     | Custom DNS resolves Bose hostnames to the local server | All devices at once; full coverage                       |
+
+Both methods require TLS when the speaker uses HTTPS to contact the service. The web UI guides you through installing the service's CA certificate on the speaker (requires SSH).
+
+**Step 7 — Reboot the speaker.**
+Power-cycle the speaker to apply the changes. After reboot it contacts the local service instead of Bose's cloud.

 ---

-### Alternative: DNS Redirection (No SSH)
-If you prefer not to modify your speakers via SSH, you can use a local DNS server (like Pi-hole, AdGuard Home, or Unbound) to point the following domains to your local server's IP:
+## Scenario B: Set up after the shutdown (or after a factory reset)

-*   `bmx.bose.com`
-*   `streaming.bose.com`
-*   `updates.bose.com`
-*   `stats.bose.com`
-*   `content.api.bose.io`
+If the Bose cloud is gone, or you've factory-reset a speaker, there's no existing account to migrate from. You start fresh with a local account.

-*Note: DNS redirection for HTTPS services requires the speakers to trust your local service's SSL certificate. The SSH-based migration handles this automatically by injecting the CA.*
+**Step 1 — Set up DNS/DHCP redirect first** (recommended).
+Configure your network's DNS to resolve the Bose cloud hostnames to the local service's address before the speaker tries to register. This way, when the speaker boots and attempts to register, it reaches AfterTouch automatically instead of failing to reach Bose.
+
+See the [SoundTouch Service Guide](SOUNDTOUCH-SERVICE.md) for the built-in DNS server configuration and the list of hostnames to redirect.
+
+**Step 2 — Connect the speaker to Wi-Fi.**
+Use the speaker's built-in AP mode or BLE setup flow. See [Device Initial Setup](DEVICE-INITIAL-SETUP.md) for factory reset button sequences and Wi-Fi provisioning.
+
+**Step 3 — Start the service and open the web UI** at `http://<server>:8000`.
+
+**Step 4 — Add the speaker.**
+After connecting to Wi-Fi, the speaker should appear in the web UI automatically (or add it manually by IP). If DNS redirect is already in place, the speaker is already communicating with AfterTouch.
+
+**Step 5 — Migrate** (if not already using DNS redirect).
+If you didn't set up DNS first, use the XML redirect method from the web UI to update the speaker's service URLs. The web UI walks you through the steps including CA certificate setup.
+
+**Step 6 — Reboot the speaker.**
+Power-cycle to ensure all changes take effect.

 ---
+
+## After migration
+
+Once migrated, your speaker uses the local service for music browsing, preset sync, and device registration. The web UI at `http://<server>:8000` is your management interface going forward. Back up the `data/` directory periodically in case you need to restore.
+
+For the complete step-by-step walkthrough with commands and troubleshooting, see the [Migration Guide](MIGRATION-GUIDE.md). For safety measures and rollback options, see the [Migration & Safety Guide](MIGRATION-SAFETY.md).

 ## 🌐 **Connection Issues**

+### ❌ Speaker logs `Curl 7, http 0` and AfterTouch sees no HTTP requests
+
+**Symptoms:**
+
+In the speaker's log (see [DEVICE-LOGGING.md](../DEVICE-LOGGING.md#1-accessing-system-logs-requires-root) for the SSH/`logread` setup — the filtered command `logread -f | grep -v '127.0.0.1'` is what you want here):
+
+```
+SimpleURLFetcher: retry needed, Curl 7, http 0
+```
+
+In the AfterTouch service log: plenty of `[DNS] Intercepted query …` lines but **zero** HTTP requests after each DNS lookup.
+
+**Cause:** speakers connect to Bose hostnames over implicit HTTPS, i.e. port **443**. AfterTouch's built-in HTTPS listener defaults to **8443** because 443 is privileged. The speaker resolves the right IP, dials `:443`, and gets connection refused — which is what `Curl 7` reports.
+
+**Verify:**
+
+```bash
+curl -ksS -o /dev/null -w "443=%{http_code}\n"  https://localhost:443/
+curl -ksS -o /dev/null -w "8443=%{http_code}\n" https://localhost:8443/
+```
+
+Expected when the misconfiguration is present: `443=000` plus a `curl: (7) Failed to connect …` line, `8443=200` (or any 3-digit code).
+
+**Fix:** route `:443` to AfterTouch's HTTPS listener — see [HTTPS-SETUP.md → Binding to port 443](HTTPS-SETUP.md#binding-to-port-443). The AfterTouch settings page shows a ✅ / ❌ indicator for `:443` reachability once the routing is in place.
+
+### ❌ Presets flash then revert to "Select a preset" after a factory reset
+
+**Symptoms:**
+
+- You factory-reset a SoundTouch (Wave / 10 / 20 / 30 / …) that was previously migrated.
+- After reconnecting it to Wi-Fi, AfterTouch sees the speaker again, but pressing a preset on the device or in the app makes the display briefly show the preset name and then revert to *"Select a preset or explore music in the SoundTouch App"*.
+- Spotify presets show the same revert unless Spotify Connect is started from the mobile app first.
+- The speaker's `/sources` is missing TUNEIN / LOCAL_INTERNET_RADIO / DEEZER / your linked Spotify account — only AUX, BLUETOOTH, AIRPLAY, the SpotifyConnectUserName placeholder, NOTIFICATION, and QPLAY appear.
+
+**Cause:**
+
+A factory reset wipes `/mnt/nv/BoseApp-Persistence/1/Marge.xml` — the file that carries the speaker's auth token for the AfterTouch (or Bose) cloud service. The migrated URL configuration is preserved (it lives in `envswitch`), so the speaker keeps talking to AfterTouch, but with no token it can't authenticate for preset playback. Separately, the device's `/sources` cache is reduced until it receives a `<sourcesUpdated/>` notification.
+
+**Fix:**
+
+1. **Re-open the Migration tab** in the AfterTouch UI. The wizard reads `/info`, sees `margeAccountUUID` is empty, and renders:
+
+   > **Current: ❌ Not paired (factory-reset or never paired) — set an ID to pair as part of Apply**
+
+   The devices list now also shows a `⚠ Not paired — re-pair` badge next to such speakers, so you don't have to remember to open the Migration tab cold.
+
+2. **Pick the previously-used account ID** from the "pick from datastore" dropdown (if AfterTouch remembers it), or click **Generate** for a fresh one.
+
+3. **Click Apply.** The wizard runs `pair-account` along with the rest, recreating `Marge.xml` on the device with the chosen ID.
+
+4. **Click Data Sync** (Tab 3). AfterTouch persists the speaker's presets/recents/sources and posts a `<sourcesUpdated/>` notification to the device — the missing TUNEIN / LOCAL_INTERNET_RADIO / DEEZER / linked Spotify entries reappear in `/sources` automatically.
+
+5. Press a preset. It should play normally.
+
+If presets still won't play after step 5, capture `logread -f | grep -v '127.0.0.1:'` on the speaker (see [DEVICE-LOGGING.md](../DEVICE-LOGGING.md#1-accessing-system-logs-requires-root)) while pressing the preset and file an issue with the snippet — the lines around the failed playback name the deeper cause.

+## 🌐 **Hostname Resolution** {#hostname-resolution}
+
+### Why the service resolves the hostname from the device
+
+When you migrate a speaker using the resolv.conf method, the service needs to write a raw IP address into the speaker's network configuration. That IP must be the address the *speaker itself* can reach — which is not necessarily the same address your computer resolves.
+
+In environments with NAT, split-horizon DNS, or Docker/container networking, `soundtouch.local` (or whatever you set as `SERVER_URL`) may resolve to a different IP depending on who is asking. The service therefore resolves the hostname by running `ping -c 1 <hostname>` over SSH on the speaker and extracting the IP from the output. This is the authoritative result: it is exactly what the speaker would use.
+
+If that SSH ping fails, migration is aborted. Writing an unresolvable or incorrectly resolved hostname into `aftertouch.resolv.conf` would silently break the speaker's DNS config and prevent it from reaching the service after reboot.
+
+**The XML migration method is different.** It writes the full URL (e.g. `http://soundtouch.local:8000`) into `SoundTouchSdkPrivateCfg.xml`. The speaker resolves the hostname at connect time, not at migration time. This means migration can proceed even if the hostname is not yet reachable — for example, when the service will be deployed under that hostname but is not running yet. A warning is still shown in the UI so you are aware, but the Confirm Migration button remains enabled.
+
+### ❌ "Cannot resolve target hostname for migration"
+
+**Symptoms** (migration log or web UI warning):
+```
+cannot resolve target hostname for migration: cannot resolve "soundtouch.local":
+SSH ping from device failed and service-side DNS lookup also failed
+```
+or:
+```
+resolved "soundtouch.local" to 192.168.1.100 from service, not from device —
+result may be wrong if NAT or split-DNS is in use
+```
+
+**What this means:**
+
+The service could not confirm the IP by running `ping` on the speaker via SSH. Either:
+- the `ping` binary is not available or not in `$PATH` on this firmware, or
+- the hostname is not resolvable from the speaker's network context.
+
+**Diagnosis — run manually over SSH:**
+
+```bash
+# SSH into the speaker
+ssh root@<speaker-ip>
+
+# Try to resolve the service hostname
+ping -c 1 soundtouch.local
+# or use the IP directly to verify connectivity
+ping -c 1 192.168.1.100
+
+# Check the speaker's current DNS config
+cat /etc/resolv.conf
+
+# Check if ping is available
+which ping
+busybox ping --help
+```
+
+**Solutions:**
+
+#### 1. Use an IP address as SERVER_URL
+
+The most reliable fix. If the hostname cannot be resolved from the device, use a raw IP instead. Resolution is skipped entirely when `SERVER_URL` contains an IP.
+
+```bash
+# In your .env
+SERVER_URL=http://192.168.1.100:8000
+HTTPS_SERVER_URL=https://192.168.1.100:8443
+```
+
+HTTPS works correctly with IP addresses — the service certificate includes the IP as a Subject Alternative Name (SAN).
+
+#### 2. Ensure the hostname resolves on the speaker's network segment
+
+If you use `soundtouch.local`, verify mDNS is working from another device on the same subnet:
+
+```bash
+avahi-resolve -n soundtouch.local    # Linux
+dns-sd -G v4 soundtouch.local        # macOS
+```
+
+#### 3. Use the XML migration method
+
+Select the XML method in the migration UI. It writes the full URL and the speaker resolves it at connect time, so hostname resolution is not required during migration. This also allows migrating to a hostname that is not yet live.

+## Phase 1 — Discovery: Is the Speaker Already Paired?
+
+```xml

+<info deviceID="{device_id}">
+  <name>SoundTouch 10</name>
+  <type>SoundTouch 10</type>
+  <margeAccountUUID>9569497</margeAccountUUID>   <!-- empty = unpaired -->
+  <margeURL>https://streaming.bose.com</margeURL>
+  ...
+</info>
+```
+
+- **Empty `margeAccountUUID`** → device is unpaired, proceed to Phase 2
+- **Populated `margeAccountUUID`** → already paired with that account ID
+
+---
+
+## Phase 2 — Pairing a New Speaker
+
+### 2.1 Setup State Machine
+
+The pairing flow uses a setup state machine on the device. States must be sent in order.
+
+```xml
+<!-- 1. Start setup -->
+<msg><header deviceID="{device_id}" url="setup" method="POST">
+  <request requestID="21"></request>
+</header><body><setupState state="SETUP_START"/></body></msg>
+
+<!-- 2. Enter identify mode — device flashes/beeps; 300 000 ms timeout -->
+<msg><header deviceID="{device_id}" url="setup" method="POST">
+  <request requestID="22"></request>
+</header><body><setupState state="SETUP_IDENTIFY_DEVICE_ENTER" timeout="300000"/></body></msg>
+
+<!-- Server pushes: -->
+<updates deviceID="{device_id}">
+  <soundTouchConfigurationUpdated>
+    <soundTouchConfigurationStatus status="SOUNDTOUCH_CONFIGURING"/>
+  </soundTouchConfigurationUpdated>
+</updates>
+
+<!-- 3. Set language (3 = German; adjust as needed) -->
+<msg><header deviceID="{device_id}" url="language" method="POST">
+  <request requestID="23"></request>
+</header><body><sysLanguage>3</sysLanguage></body></msg>
+
+<!-- 4. Enter setup (user has confirmed identification) -->
+<msg><header deviceID="{device_id}" url="setup" method="POST">
+  <request requestID="24"></request>
+</header><body><setupState state="SETUP_ENTER"/></body></msg>
+
+<!-- 5. Leave identify mode -->
+<msg><header deviceID="{device_id}" url="setup" method="POST">
+  <request requestID="25"></request>
+</header><body><setupState state="SETUP_IDENTIFY_DEVICE_LEAVE"/></body></msg>
+
+<!-- 6. Set device name -->
+<msg><header deviceID="{device_id}" url="name" method="POST">
+  <request requestID="26"></request>
+</header><body><name>My SoundTouch 10</name></body></msg>
+```
+
+### 2.2 Account Pairing — The Critical Step
+
+```xml
+<!-- C→S: pair device with account -->
+<msg><header deviceID="{device_id}" url="setMargeAccount" method="POST">
+  <request requestID="27"></request>
+</header><body>
+  <PairDeviceWithAccount>
+    <accountId>{accountId}</accountId>
+    <userAuthToken>Bearer {token}</userAuthToken>
+  </PairDeviceWithAccount>
+</body></msg>
+
+<!-- S→C: device info response with margeAccountUUID now set -->
+<info deviceID="{device_id}">
+  ...
+  <margeAccountUUID>{accountId}</margeAccountUUID>
+  ...
+</info>
+```
+
+The server also pushes several `sourcesUpdated` events after successful pairing.
+
+**`{accountId}`** — the numeric Bose account ID (e.g. `9569497`), obtainable from
+`GET /streaming/account/login` on soundtouch-service.
+
+**`{token}`** — a Bearer token issued by Bose authentication (or soundtouch-service).
+The full token from the captures:
+```
+Bearer NtJDRbNtY3hDhm5K8FC2JprRhRQNH3QdZjG6aR4ASwYQg4rvZMY6dPLc3Bm6zvWNciWzCpMWZ/dbITRQoVdClOdssgDO+Nlh4ZJWp2w3tZiGzB8Flho0c+ipXnT/0Yg5
+```
+(session-specific; obtain a fresh one from the service's account login flow)
+
+### 2.3 Finish Setup and Telemetry
+
+```xml
+<!-- Leave setup state machine -->
+<msg><header deviceID="{device_id}" url="setup" method="POST">
+  <request requestID="28"></request>
+</header><body><setupState state="SETUP_LEAVE"/></body></msg>
+
+<!-- Trigger device to sync customer support info to Marge cloud -->
+<msg><header deviceID="{device_id}" url="pushCustomerSupportInfoToMarge" method="GET">
+  <request requestID="29"></request>
+</header></msg>
+
+<!-- S→C: -->
+<status>/pushCustomerSupportInfoToMarge</status>
+```
+
+---
+
+## Phase 3 — Unpairing
+
+```xml
+<!-- C→S: remove device from account -->
+<msg><header deviceID="{device_id}" url="setMargeAccount" method="POST">
+  <request requestID="24">
+    <info mainNode="removeDevice" type="new"/>
+    <sourceItem source="SETTINGS" sourceAccount="{device_id}"/>
+  </request>
+</header><body><UnPairDeviceWithAccount/></body></msg>
+
+<!-- S→C: response with device info showing empty margeAccountUUID -->
+<!-- Server also pushes: <updates><infoUpdated/></updates> -->
+```
+
+---
+
+## Phase 4 — App Initialization (Bulk State Fetch)
+
+When the app connects to an already-paired device it sends these in rapid parallel sequence:
+
+```
+info          (GET)  — device metadata, check pairing
+sources       (GET)  — available input sources
+presets       (GET)  — saved presets 1–6
+swUpdateQuery (POST) — check if update is in progress
+capabilities  (GET)  — hardware capabilities, network config
+bassCapabilities (GET) — bass range and defaults
+now_playing   (GET)  — current playback state
+volume        (GET)  — current volume
+getZone       (GET)  — multi-room zone membership
+clockDisplay  (POST) — set clock timezone/format
+```
+
+Then a second wave:
+
+```
+swUpdateCheck   (POST) — check for new firmware
+systemtimeout   (GET)  — power-saving timeout
+rebroadcastlatencymode (GET) — zone latency mode
+getGroup        (GET)  — stereo-pair group
+language        (GET, sourceItem source="settings") — UI language
+bass            (GET)  — current bass level
+serviceAvailability (GET, sourceItem source="add_service" or "settings")
+webserver/pingRequest (GET) — keepalive
+pushCustomerSupportInfoToMarge (GET) — telemetry
+netStats        (GET, sourceItem source="settings") — network statistics
+introspect      (POST, sourceItem source="AIRPLAY") — AirPlay2 capabilities
+```
+
+`clockDisplay` example with timezone:
+```xml
+<clockDisplay>
+  <clockConfig timezoneInfo="Europe/Berlin" timeFormat="TIME_FORMAT_12HOUR_ID"/>
+</clockDisplay>
+```
+
+`serviceAvailability` response lists availability of all service types (PANDORA, AIRPLAY,
+AMAZON, DEEZER, SPOTIFY, TUNEIN, SIRIUSXM_EVEREST, BLUETOOTH, etc.) with `isAvailable`
+and optional `reason` attributes.
+
+---
+
+## Playback Control
+
+### Start Playback via `playbackRequest` (preferred — bypasses source checks)
+
+```xml
+<msg><header deviceID="{device_id}" url="playbackRequest" method="POST">
+  <request requestID="{n}"><info type="new"/></request>
+</header><body>
+  <playbackRequest source="TUNEIN" sourceAccount="">
+    <container type="stationurl"
+               location="/v1/playback/station/s25260"
+               isPresetable="true"
+               source="TUNEIN"
+               sourceAccount="">
+      <itemName>1LIVE</itemName>
+    </container>
+  </playbackRequest>
+</body></msg>
+
+<!-- S→C response: -->
+<playbackResponse source="TUNEIN" sourceAccount=""/>
+
+<!-- S→C pushes: nowPlayingUpdated, recentsUpdated -->
+```
+
+For a TuneIn podcast episode, use `type="tracklisturl"` and
+`location="/v1/playback/episodes/{id}?encoded_name={base64}"`.
+
+### Select Content via `select` (triggers preset/recents UI highlight)
+
+```xml
+<msg><header deviceID="{device_id}" url="select" method="POST">
+  <request requestID="{n}"><info type="new"/></request>

+               sourceAccount="TUNEIN"
+               isPresetable="true">
+    <itemName>1LIVE</itemName>
+  </ContentItem>
+</body></msg>
+```
+
+Note: `select` with a TUNEIN item that the device can't resolve directly may return
+`error value="1005" name="UNKNOWN_SOURCE_ERROR"`. Use `playbackRequest` instead for
+reliable playback.
+
+### Special: Select Last Wi-Fi Source
+
+A plain-text (non-XML) client message:
+```
+selectLastWiFiSource
+```
+
+Server responds with plain text:
+```
+<?xml version="1.0" encoding="UTF-8" ?><status>/selectLastWiFiSource</status>
+```
+
+### Key Presses
+
+```xml
+<!-- press -->

+```
+
+Key names observed: `POWER`, `STOP`, `PAUSE`, `ADD_FAVORITE`
+
+`sender="Gabbo"` is the app identifier string used by all Bose mobile apps.
+
+### Volume
+
+```xml
+<!-- Set volume (0–100) -->
+<msg><header deviceID="{device_id}" url="volume" method="POST">

 - 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.

+
+## 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>
+```
