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

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

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

+```
+
+### Issue 2: Request Flow Complexity
+
+Current middleware execution order:
+```
+1. MirrorMiddleware    - Buffers body, creates clones
+2. RecordMiddleware    - Also buffers body
+3. Application Handler - Processes request
+4. Mirror Execution    - Async/sync mirror to upstream
+5. Recording           - Multiple recording points
+```
+
+Problems:
+- Multiple body reads across middleware chain
+- Inconsistent request state between clones
+- Race conditions in async scenarios
+- No guarantee of request equivalence
+
+## Proposed Solution: Context-Bound Request Snapshots
+
+### Core Concept
+
+Create **immutable request snapshots** early in the request lifecycle and propagate them through the **Request Context**. This ensures all downstream consumers (Mirroring, Recording, Parity Check) use identical data without re-reading the request body.
+
+### Architecture (Context-Only)
+
+```
+┌─────────────────┐
+│ Original Request│
+└─────────┬───────┘
+          │
+          ▼
+┌─────────────────┐    ┌──────────────────┐
+│ Snapshot Creator│───▶│ Request Context  │
+│  (Middleware)   │    │ (Pointer-based)  │
+└─────────┬───────┘    └──────────────────┘

+          ▼                      │ (Safe for async)
+┌─────────────────┐              │

+      │Handler │ │Execution│ │  System      │
+      └────────┘ └─────────┘ └──────────────┘
+```
+
+### Request Snapshot Structure
+
+```go
+type RequestSnapshot struct {
+    Method    string
+    URL       *url.URL
+    Headers   http.Header
+    Body      []byte
+    Host      string
+    Timestamp time.Time
+}
+
+// Typed key for context safety
+type contextKey struct{ name string }
+var SnapshotKey = &contextKey{"request_snapshot"}
+```
+
+### Implementation Strategy
+
+#### Phase 1: Snapshot Middleware
+
+```go
+func (s *Server) SnapshotMiddleware(next http.Handler) http.Handler {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        // 1. Capture body once with size limit (e.g. 2MB)
+        body, _ := io.ReadAll(io.LimitReader(r.Body, 2*1024*1024))
+        r.Body.Close()
+
+        // 2. Create snapshot
+        snapshot := &RequestSnapshot{
+            Method:    r.Method,
+            URL:       cloneURL(r.URL),
+            Headers:   r.Header.Clone(),
+            Body:      body,
+            Host:      r.Host,
+            Timestamp: time.Now(),
+        }
+
+        // 3. Inject pointer into context
+        ctx := context.WithValue(r.Context(), SnapshotKey, snapshot)
+
+        // 4. Restore r.Body for downstream compatibility
+        r = r.WithContext(ctx)
+        r.Body = io.NopCloser(bytes.NewReader(snapshot.Body))
+
+        next.ServeHTTP(w, r)
+    })
+}
+```
+
+#### Phase 2: Downstream Consumption
+
+Consumers (Mirror/Record) retrieve the snapshot directly from context:
+
+```go
+snapshot, ok := r.Context().Value(SnapshotKey).(*RequestSnapshot)
+if ok {
+    // Use snapshot.Body directly instead of io.ReadAll(r.Body)
+}
+```
+
+## Hardware Considerations (Raspberry Pi Zero 2W)
+
+To protect MicroSD health and optimize for limited memory:
+
+1. **No Intermediate Disk Storage**: Snapshots exist only in memory; they are never written to disk until the final `.http` recording is generated.
+2. **Memory Management**: Use `sync.Pool` for temporary buffers to reduce GC churn on the single-core/low-memory SoC.
+3. **Automatic Cleanup**: Snapshots are naturally garbage collected once the Request Context and all child goroutines (detached mirrors/recordings) finish.
+4. **Body Capping**: Strict limits on snapshot size prevent OOM (Out-of-Memory) conditions.
+
+#### Phase 2: Response Capture System
+
+```go
+type ResponseRecorder struct {
+    http.ResponseWriter
+    snapshot     *ResponseSnapshot
+    snapshotID   string
+    source       string
+    startTime    time.Time
+}
+
+func (r *ResponseRecorder) WriteHeader(statusCode int) {
+    r.snapshot.StatusCode = statusCode
+    r.snapshot.Headers = r.Header().Clone()
+    r.ResponseWriter.WriteHeader(statusCode)
+}
+
+func (r *ResponseRecorder) Write(data []byte) (int, error) {
+    r.snapshot.Body = append(r.snapshot.Body, data...)
+    return r.ResponseWriter.Write(data)
+}
+
+func (r *ResponseRecorder) finalize() {
+    r.snapshot.Duration = time.Since(r.startTime)
+    r.snapshot.Timestamp = time.Now()
+}
+```
+
+#### Phase 3: Recording System Integration
+
+```go
+type RecordingManager struct {
+    storage   SnapshotStorage
+    recorder  *Recorder
+    patterns  []string
+}
+
+func (rm *RecordingManager) RecordInteraction(snapshotID string, response *ResponseSnapshot) {
+    // Retrieve immutable request snapshot
+    request, exists := rm.storage.Get(snapshotID)
+    if !exists {
+        log.Printf("Request snapshot not found: %s", snapshotID)
+        return
+    }
+
+    // Record with guaranteed data integrity
+    rm.recorder.RecordInteraction(request, response)
+}
+
+func (r *Recorder) RecordInteraction(req *RequestSnapshot, res *ResponseSnapshot) error {
+    // Generate .http file with complete data
+    var buf bytes.Buffer
+
+    // Write request
+    fmt.Fprintf(&buf, "### %s %s\n", req.Method, req.URL.String())
+    fmt.Fprintf(&buf, "%s %s\n", req.Method, req.URL.String())
+    fmt.Fprintf(&buf, "Host: %s\n", req.Host)
+
+    for k, vv := range req.Headers {
+        for _, v := range vv {
+            fmt.Fprintf(&buf, "%s: %s\n", k, v)
+        }
+    }
+
+    buf.WriteString("\n")
+    buf.Write(req.Body)
+    buf.WriteString("\n\n")
+
+    // Write response
+{% raw %}
+    buf.WriteString("> {% \n")
+{% endraw %}
+    fmt.Fprintf(&buf, "    // Response: %d %s\n", res.StatusCode, http.StatusText(res.StatusCode))
+    buf.WriteString("    // Headers:\n")
+
+    for k, vv := range res.Headers {
+        for _, v := range vv {
+            fmt.Fprintf(&buf, "    // %s: %s\n", k, v)
+        }
+    }
+
+{% raw %}
+    buf.WriteString("%}\n\n")
+{% endraw %}
+
+    if len(res.Body) > 0 {
+        buf.WriteString("/*\n")
+        buf.Write(res.Body)
+        buf.WriteString("\n*/\n")
+    } else {
+        buf.WriteString("// [Binary response body: 0 bytes]\n")
+    }
+
+    // Write to file
+    return r.writeToFile(buf.Bytes(), req, res)
+}
+```
+

+# SCMUDC Enrichment Implementation Summary
+
+## Overview
+
+This document summarizes the implementation of SCMUDC (Sound Control Management Usage Data Collection) event enrichment in the AfterTouch toolkit. The enhancement provides human-readable analysis of device telemetry data to improve usability and debugging capabilities.
+
+## Problem Solved
+
+Previously, SCMUDC telemetry events were stored as raw JSON with Base64-encoded XML content, making them difficult to analyze. Users had to manually decode content to understand what device interactions were being recorded.
+
+## Solution Implemented
+
+### 1. Backend Enrichment (`pkg/service/proxy/`)
+
+#### New File: `scmudc.go`
+- **SCMUDCRequest/SCMUDCEvent Structs**: Parse incoming telemetry JSON
+- **EnrichedSCMUDCEvent Struct**: Human-readable analysis with decoded content
+- **DecodedContent Struct**: Parsed XML metadata (track names, artwork URLs, etc.)
+- **enrichSCMUDCRequest()**: Main enrichment function that:
+  - Identifies event origin (app, hardware, or internal system)
+  - Decodes Base64 XML content for device events
+  - Creates human-readable summaries
+- **Helper Functions**: Button formatting, content summarization, origin descriptions
+
+#### Enhanced File: `recorder.go`
+- **Updated save() method**: Extracts SCMUDC data during recording
+- **New writeRequestWithEnrichment()**: Adds enriched comments to .http files
+- **New writeResponseWithEnrichment()**: Includes SCMUDC analysis in response section
+- **Updated Interaction struct**: Added `SCMUDCData` field for API responses
+- **New extractSCMUDCFromFile()**: Parses enrichment data from existing .http files
+- **Enhanced parseInteractionFile()**: Populates SCMUDC data when listing interactions
+
+### 2. Frontend Enhancement
+
+#### Updated HTML (`pkg/service/handlers/web/index.html`)
+- **New Column**: Added "Event Details" to interactions table
+- **Table Structure**: Updated to accommodate SCMUDC enrichment display
+
+#### Enhanced JavaScript (`pkg/service/handlers/web/js/script.js`)
+- **Updated fetchInteractions()**: Displays enriched SCMUDC data with icons
+- **New Helper Functions**:
+  - `getOriginIcon()`: Maps origins to emojis (📱 App, 🎛️ Hardware, 🔄 Internal)
+  - `getActionIcon()`: Maps actions to emojis (▶️ Play, ⏸️ Pause, etc.)
+  - `showSCMUDCDetails()`: Detailed popover for complex events
+  - `displaySCMUDCPopover()`: Modal dialog with full decoded content
+- **Truncation Logic**: Long content shows "(...)" with click-to-expand
+
+## Event Origin Clarification
+
+Based on analysis of recorded data:
+
+| Origin | Source | Description | Example Events |
+|--------|--------|-------------|----------------|
+| `gabbo` | **SoundTouch App** | Mobile/desktop app UI interactions | Play, Pause, Power via app |
+| `console` | **Device Hardware** | Physical buttons on speaker | Preset buttons, hardware power |
+| `device` | **Internal System** | Automatic device responses | Content playback, system actions |
+
+## Enhanced .http File Format
+
+### Before (Raw)
+```http
+### POST /v1/scmudc/A81B6A536A98
+POST /v1/scmudc/A81B6A536A98
+Host: events.api.bosecm.com
+...
+
+{"envelope":...,"payload":{"events":[{"data":{"contentItem":"PD94bWw..."}}]}}
+```
+
+### After (Enriched)
+```http
+### POST /v1/scmudc/A81B6A536A98
+// Origin: Internal System (device)
+// Action: play-item
+// Command: Billie Eilish - bad guy (instrumental version)
+// Summary: Device: Spotify: Billie Eilish - bad guy (instrumental version)
+//
+// Decoded Content:
+// - Source: SPOTIFY
+// - Item: Billie Eilish - bad guy (instrumental version)
+// - Account: gesellix
+// - Artwork: https://i.scdn.co/image/ab67616d0000b273...
+//
+// Full XML Content:
+// <?xml version="1.0" encoding="UTF-8"?>
+// <ContentItem source="SPOTIFY" type="tracklisturl" ...>
+//     <itemName>Billie Eilish - bad guy (instrumental version)</itemName>
+//     <containerArt>https://i.scdn.co/image/ab67616d0000b273...</containerArt>
+// </ContentItem>
+POST /v1/scmudc/A81B6A536A98
+...
+
+{% raw %}
+> {%
+    // Response: 200 OK
+    // SCMUDC Event Analysis:
+    // - Origin: Internal System (device)
+    // - Action: play-item
+    // - Summary: Device: Spotify: Billie Eilish - bad guy (instrumental version)
+    // - Content: Billie Eilish - bad guy (instrumental version)
+    // - Account: gesellix
+%}
+{% endraw %}
+```
+
+## Web UI Enhancement
+
+### Interactions Table
+- **New Column**: "Event Details" shows enriched summaries
+- **Visual Icons**: Origin and action type indicators
+- **Truncation**: Long content abbreviated with "(...)" expansion
+- **Backward Compatibility**: Works with existing recordings
+
+### Event Details Display
+```
+📱 ▶️ Play Button                    (Simple app action)
+🔄 🎵 Billie Eilish - bad guy... (...)  (Complex device event with details)
+🎛️ ⭐ Preset 5                        (Hardware preset button)
+```
+
+### Detailed Popover
+For complex events, clicking "(...)" shows:
+- **Origin Description**: "SoundTouch App" instead of "gabbo"
+- **Full Content Information**: Track names, artwork URLs, account details
+- **Complete XML**: Formatted and readable content item data
+
+## Implementation Benefits
+
+### For Users
+- **Immediate Recognition**: See what actions were performed without decoding
+- **Better Debugging**: Quick identification of app vs. hardware vs. system events
+- **Rich Context**: Track names, accounts, and content sources visible at a glance
+
+### For Developers
+- **Structured Data**: Consistent parsing and enrichment pipeline
+- **Extensible**: Easy to add new event types and origins
+- **Backward Compatible**: Existing recordings work without re-processing
+
+### For Analysis
+- **Pattern Recognition**: Quickly identify user behavior patterns
+- **Service Integration**: See which music services are being used
+- **Device Usage**: Understand app vs. hardware control preferences
+

+```
+
+## Technical Decisions
+
+### Base64 Decoding Strategy
+- **When**: During recording (not on-demand) for performance
+- **Fallback**: Parse from .http files if enrichment missing
+- **Storage**: Both enriched comments and structured data in API responses
+
+### Icon Selection
+- **Emoji Usage**: Universal, colorful, intuitive recognition
+- **Semantic Mapping**: Icons match function (📱 for app, 🎛️ for hardware)
+- **Fallback**: Generic icons (❓, 🔘) for unknown types
+
+### Backward Compatibility
+- **Graceful Degradation**: Missing enrichment data doesn't break UI
+- **File Parsing**: Extract enrichment from existing .http files
+- **API Enhancement**: New fields optional in Interaction struct
+
+## Future Enhancement Opportunities
+
+1. **Event Correlation**: Link device events to user actions
+2. **Statistics Dashboard**: Origin-based usage analytics
+3. **Content Recommendations**: Track listening patterns
+4. **Device Health**: Monitor interaction frequency and patterns
+5. **Export Features**: CSV/JSON export of enriched event data
+
+## Testing Considerations
+
+- **Edge Cases**: Malformed Base64, missing XML elements
+- **Performance**: Large numbers of SCMUDC events
+- **Browser Compatibility**: Emoji display across different browsers
+- **Data Validation**: Ensure enrichment doesn't introduce errors
+
+This implementation significantly improves the usability of SCMUDC telemetry data while maintaining full backward compatibility and raw data access for advanced users.

+# Undocumented Community Features & API Discoveries
+This document captures advanced API endpoints and device behaviors discovered by the SoundTouch community through reverse engineering projects like **SoundCork** and **ÜberBöse API**. These features are not documented in the official Bose SoundTouch Web API v1.0 but are crucial for full device emulation and offline operation.
+## Cloud Emulation (Marge/BMX) Discoveries
+While the local `/8090` API is well-documented, the cloud-side service emulation reveals deeper device integration points.
+### 1. Stereo Pairing & Cloud-Side Grouping
+SoundCork has pioneered the emulation of "Marge" group endpoints, which differ from the local `/getGroup` API. These are primarily used for persistent configurations like **Stereo Pairs** (e.g., two ST-10s).
+- **GET** `/marge/streaming/account/{account}/device/{device}/group`
+  Returns `<group/>` if ungrouped, or full group configuration for stereo pairs.
+- **POST** `/marge/streaming/account/{account}/group`
+  Creates a new group (returns a 7-digit group ID). Used for initial pairing.
+- **DELETE** `/marge/streaming/account/{account}/group/{group}`
+  Dissolves a group configuration.
+### 2. Device Analytics & Event Reporting
+Devices report real-time telemetry to the cloud. Intercepting these provides a window into device usage without polling.
+- **Endpoint**: `POST /v1/scmudc/{deviceId}`
+- **Function**: Submits event data including `play-state-changed`, `preset-pressed`, `power-pressed`, `source-state-changed`, and `art-changed` (Metadata updates). This endpoint was first extensively documented in the **ÜberBöse API** specification.
+### 3. Power-On Lifecycle
+When a SoundTouch device boots or "powers on" (distinct from waking from standby), it contacts specific support endpoints.
+- **Endpoint**: `POST /streaming/support/power_on`
+- **Behavior**: Reports device serial number, IP address, and diagnostic data.
+- **Critical Finding**: SoundTouch devices fetch `TUNEIN` and `LOCAL_INTERNET_RADIO` source availability from the cloud **ONLY at boot time**. If the cloud is unreachable during a hard reboot (power cycle), these sources will disappear from the device's `/sources` list and become unavailable, even if the local API is working. This behavior was analyzed and reported by the **ÜberBöse API** project (Issue #3).
+### 4. OAuth & Service Tokens
+Integration with music services (Spotify, Pandora, etc.) involves specific token management endpoints.
+- **Endpoint**: `POST /oauth/device/{deviceId}/music/musicprovider/{providerId}/token/{tokenType}`
+- **Usage**: Used to refresh or validate session tokens for cloud-based music providers.
+## Community-Driven Extensions
+The community is working on extending SoundTouch functionality beyond its original design.
+### 1. Radio-Browser.info Integration
+There is an active effort to add `radio-browser.info` as a native `sourceprovider`. This would allow devices to browse a massive directory of thousands of stations without relying on the TuneIn cloud service.
+- **Status**: Research phase in SoundCork (Issue #150).
+- **Implementation**: Requires adding a new source provider entry in the emulated `/streaming/sourceproviders` response.
+### 2. Stockholm Internal App Analysis
+Deep analysis of the Stockholm (device firmware) internal web application reveals a set of internal AJAX/XML calls used by the device's own control interface.
+- **Internal Domains**: `Marge` (XML-based) and `Gabbo` (App-send based).
+- **Reference**: See SoundCork Issue #128 for a comprehensive list of internal JS controllers and their functions.
+### 3. ETag Case-Sensitivity Bug
+The SoundTouch device firmware has a case-sensitivity bug regarding HTTP `ETag` headers.
+- **Discovery**: SoundCork Issue #129.
+- **Detail**: The device expects the `ETag` header to be exactly title-cased. If a server returns `etag` (lowercase), the device fails to use it for `If-None-Match` requests, breaking efficient preset synchronization.
+- **Solution**: Force title-casing of the header via a reverse proxy like Nginx or mitmproxy.

+# Device Redirect Methods & Custom Service Setup
+
+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. This document outlines the three known methods to achieve this, gathered from community reverse-engineering efforts in the **SoundCork** and **ÜberBöse API** projects.
+
+## Overview of Redirection Targets
+
+SoundTouch devices primarily communicate with the following domains:
+- `streaming.bose.com`: Marge (Account and streaming services)
+- `updates.bose.com`: Software updates
+- `stats.bose.com`: Telemetry and analytics
+- `bmx.bose.com`: Bose Media eXchange registry
+- `events.api.bosecm.com`: Stockholm app analytics
+- `bose-prod.apigee.net`: Apigee gateway (used by some services)
+- `worldwide.bose.com`: Software update metadata and secondary services
+
+---
+
+## Method 1: XML Configuration Modification (Recommended)
+
+The most robust and granular method involves modifying the device's private configuration file. This is the primary method used by **SoundCork**'s migration logic to redirect devices to a local service instance.
+
+### Technical Details
+- **File Path**: `/opt/Bose/etc/SoundTouchSdkPrivateCfg.xml`
+- **Mechanism**: The device firmware reads this XML file at boot to determine service URLs.
+- **Fields to Modify**:
+  - `<margeServerUrl>`: Redirects account/streaming calls.
+  - `<statsServerUrl>`: Redirects telemetry.
+  - `<swUpdateUrl>`: Redirects update checks.
+  - `<bmxRegistryUrl>`: Redirects service discovery.
+
+### Implementation
+Requires SSH access to the device.
+```xml
+<SoundTouchSdkPrivateCfg>
+  <margeServerUrl>http://192.168.1.10:8000/marge</margeServerUrl>
+  <statsServerUrl>http://192.168.1.10:8000</statsServerUrl>
+  <swUpdateUrl>http://192.168.1.10:8000/updates/soundtouch</swUpdateUrl>
+  <bmxRegistryUrl>http://192.168.1.10:8000/bmx/registry/v1/services</bmxRegistryUrl>
+</SoundTouchSdkPrivateCfg>
+```
+
+### Pros & Cons
+| Pros | Cons |
+| :--- | :--- |
+| **Granular Control**: Redirect specific services while leaving others (e.g., updates) intact. | **Requires SSH**: Must have root/SSH access to the device. |
+| **Persistent**: Survives software updates (usually). | **Syntax Sensitive**: Errors in XML can cause boot issues or service failures. |
+| **Native**: Uses the device's built-in configuration mechanism. | |
+
+---
+
+## Method 2: `/etc/hosts` DNS Override
+
+This method uses the standard Linux hosts file to redirect traffic at the network level within the device. It is often used as a quick alternative in the **ÜberBöse API** community for global redirection.
+
+### Technical Details
+- **File Path**: `/etc/hosts`
+- **Mechanism**: Overrides DNS resolution for Bose domains to point to a local IP.
+- **Resolution Order**: SoundTouch devices use the standard Linux Name Service Switch (`/etc/nsswitch.conf`). The default configuration (`hosts: files dns`) ensures that `/etc/hosts` is consulted *before* any external DNS lookups. This makes the redirection highly reliable for all system processes, including `curl`, `BoseApp`, and `IoT`.
+
+### Implementation
+Requires SSH access. Add entries for the target domains:
+```text
+192.168.1.10  streaming.bose.com
+192.168.1.10  updates.bose.com
+192.168.1.10  stats.bose.com
+```
+
+### Pros & Cons
+| Pros | Cons |
+| :--- | :--- |
+| **Simple**: Easy to understand and implement. | **Requires SSH**: Must have root access. |
+| **Universal**: Affects all processes on the device attempting to reach those domains. | **HTTPS Issues**: Redirecting HTTPS domains to a local IP will cause SSL certificate errors unless the device is patched to skip verification or trust a custom CA. |
+| | **Brittle**: Some firmware versions may overwrite `/etc/hosts` on reboot. |
+
+---
+
+## Method 3: Binary Patching
+
+A low-level approach where the actual compiled binaries (e.g., `BoseApp`, `IoT`) are modified to change hardcoded URL patterns. Research into these patterns has been documented in both **SoundCork** (Issue #128) and **ÜberBöse API** research.
+
+### Technical Details
+- **Target Binaries**: `/opt/Bose/BoseApp`, `/opt/Bose/IoT`, `/opt/Bose/lib/libBmxAccountHsm.so`
+- **Mechanism**:
+    - **URL Replacement**: Using a hex editor to search for string patterns like `https://streaming.bose.com` and replacing them with a custom URL of the **exact same length**.
+    - **Regex Neutralization**: Some libraries (like `libBmxAccountHsm.so`) perform a validation check called `IsItBose` using a hardcoded regex. This regex prevents the device from connecting to non-Bose domains even if the URL is changed in the configuration.
+
+#### The `IsItBose` Regex Patch
+Research in the **SoundCork** community (Issue #62) identified a specific regex in `libBmxAccountHsm.so` that enforces Bose/Apigee domain usage:
+`^https:\/\/bose-[a-zA-Z0-9\.\_\-\$\%]\+\.apigee\.net\/`
+
+By patching this regex to be more "lax", the device can be made to accept any custom domain.
+
+**Example Patch**:
+Using `sed` to replace the strict regex with a broad match while preserving the original string length:
+```bash
+sed "s#\^https:....bose.\+apigee..net..#http[aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa]*#g" \
+< libBmxAccountHsm.so.orig > libBmxAccountHsm.so.patched
+```
+
+### Implementation
+1. Copy the target binary or library from the device to a PC.
+2. Use a hex editor or `sed` to locate and patch the URL strings or regex patterns.
+3. Copy the patched file back to the device.
+4. Restore execution permissions and reboot.
+
+### Pros & Cons
+| Pros | Cons |
+| :--- | :--- |
+| **Bypass Config**: Works even if the firmware ignores XML settings. | **High Risk**: Modifying binaries can lead to permanent bricks or boot loops. |
+| **Hardcoded Redirects**: Can catch URLs that aren't exposed in configuration files. | **Length Constraint**: Custom URLs must fit within the space of the original strings. |
+| | **Firmware Specific**: Patches must be reapplied after every software update. |
+| | **Complexity**: Requires understanding of binary structures and potential checksums. |
+
+---
+
+## Comparison & Usage Strategy
+
+### Summary Table
+
+| Method | Primary Use Case | Ease | Safety | Persistence | Granularity |
+| :--- | :--- | :---: | :---: | :---: | :---: |
+| **XML Config** | Logical service redirection | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
+| **`/etc/hosts`** | Quick global DNS override | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐ | ⭐⭐ |
+| **Binary Patch** | Bypassing hardcoded checks | ⭐ | ⭐ | ⭐ | ⭐⭐⭐ |
+
+---
+
+## Combining Methods: When is one not enough?
+
+A common question is whether these methods can be used in isolation or if they must be combined. The answer depends on your specific firmware version and the target service.
+
+### Scenario A: XML Config Only (The Ideal Case)
+If your firmware does not strictly enforce the `IsItBose` check for the specific URLs you are changing, **Method 1 (XML)** is sufficient. This is the cleanest approach and is used by the `soundtouch-service` migration tool.
+
+### Scenario B: XML Config + Binary Patching (The "Locked" Case)
+On some newer firmware versions, even if you change the `<margeServerUrl>` in the XML to `http://192.168.1.10`, the internal library (`libBmxAccountHsm.so`) will validate the string against the hardcoded Bose regex.
+*   **Symptom**: The device ignores the XML setting or fails to connect despite the correct URL being present.
+*   **Solution**: You **must** apply the **Binary Patch (Method 3)** to neutralize the `IsItBose` check *in addition* to the XML change.
+
+### Scenario C: `/etc/hosts` + Custom CA (The "Clean Deep Redirect")
+If you use `/etc/hosts` to point `streaming.bose.com` to a local IP and want to avoid binary patching.
+*   **Requirement 1**: Your local server must handle HTTPS (port 443).
+*   **Requirement 2**: You must inject your Root CA into the device's trust store.
+*   **Automated Tool**: The `soundtouch-service` now supports this via the `/setup/migrate/{deviceIP}?method=hosts` endpoint.
+*   **CA Download**: You can download the auto-generated Root CA from `http://<your-server>:8000/setup/ca.crt`.
+*   **Benefit**: Maintains system integrity (no binary changes) and full end-to-end encryption.
+
+### Scenario D: `/etc/hosts` + Binary Patching (The "Legacy Deep Redirect")
+If you cannot or do not want to manage certificates, but still use `/etc/hosts` for DNS redirection.
+*   **Requirement 1**: Your local server must handle HTTPS (port 443).
+*   **Requirement 2**: Since the certificate will be invalid (mismatched domain/CA), you must patch the binary to **skip SSL verification** (see [Option 2](#option-2-ssl-verification-bypass) below).
+*   **Risk**: Less secure and higher risk of bricking due to binary modification.
+
+### Scenario E: The Triple-Threat (Total Control)
+For developers creating a completely isolated "dark" environment (no internet at all):
+1.  **XML**: Point all URLs to local services.
+2.  **Binary Patch**: Neutralize `IsItBose` to allow non-Bose domains/IPs.
+3.  **`/etc/hosts`**: Redirect hardcoded domains that aren't exposed in the XML (like analytics or NTP) to prevent leakage to the real Bose cloud.
+4.  **Process Instrumentation**: Use [SoundTouch Hook](https://github.com/CodeFinder2/bose-soundtouch-hook) to monitor and override internal behavior in real-time. This is particularly useful for handling unknown hostnames or deep-hooking into service discovery logic that might bypass standard DNS lookups.
+
+---
+
+## Handling HTTPS & SSL Certificates
+
+When redirecting HTTPS traffic to a custom service, SoundTouch devices will fail the SSL handshake because they do not trust your local server's certificate.
+
+### Option 1: Custom CA Certificate (Recommended)
+
+As suggested by community members, you can configure the device to trust your own Root CA. This allows for secure HTTPS communication without patching binaries.
+
+**Technical Steps**:
+1.  **Generate a Root CA** and issue a certificate for the target domain (e.g., `streaming.bose.com`).
+2.  **SSH into the device** and copy your `rootCA.crt` to `/usr/share/ca-certificates/custom/`.
+3.  **Update the Trust Store**:
+    - **Method A (Append to Bundle)**: `cat /usr/share/ca-certificates/custom/rootCA.crt >> /etc/pki/tls/certs/ca-bundle.crt`
+    - **Method B (Symlinks)**: Add the certificate to `/etc/ssl/certs/` and create a hash symlink using `c_rehash` (if available) or manual mapping.
+
+**Pros & Cons**:
+| Pros | Cons |
+| :--- | :--- |
+| **Secure**: Maintains end-to-end encryption. | **Requires SSH**: Must have root access to modify the trust store. |
+| **Clean**: No binary patching required for SSL bypass. | **Update Risk**: Firmware updates might overwrite the `ca-bundle.crt`. |
+
+### Option 2: SSL Verification Bypass
+
+If you cannot or do not want to manage certificates, you can patch the binary to skip certificate verification.
+
+**Target**: `libBmxAccountHsm.so` or `BoseApp`
+**Mechanism**: Locating the SSL verification function (often in the internal curl-based or openssl-based logic) and forcing it to return "Success" regardless of the certificate status.
+
+---
+
+## Recommendation
+
+1.  **Start with Method 1 (XML Modification)**. It is the least invasive and most likely to work across different models.
+2.  **Verify connectivity**. If the device refuses to connect to your custom endpoint, check logs for "IsItBose" or validation failures.
+3.  **Apply Method 3 (Binary Patching)** only if Method 1 is being actively blocked by the firmware's validation logic.
+4.  **Avoid Method 2 (`/etc/hosts`)** unless you are prepared to handle SSL certificate complexities or are performing quick temporary tests.

+# IoT Configuration Analysis
+
+## Overview
+
+This document provides a detailed analysis of the AWS IoT configuration system used by Bose SoundTouch devices, based on firmware backup analysis from ST10 and ST20 models.
+
+## Configuration Files
+
+### IoT.xml Location and Content
+
+The IoT configuration is stored in XML format at:
+- **Path**: `/mnt/nv/BoseApp-Persistence/1/IoT.xml`
+- **Purpose**: Contains AWS IoT Core connection parameters
+
+#### ST20 Configuration
+```xml
+<?xml version="1.0" encoding="UTF-8" ?>
+<Configuration clientID="uuid1"
+               iotEndpoint="a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com"
+               deployment="PROD" />
+```
+
+#### ST10 Configuration
+```xml
+<?xml version="1.0" encoding="UTF-8" ?>
+<Configuration clientID="uuid2"
+               iotEndpoint="a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com"
+               deployment="PROD" />
+```
+
+### Key Observations
+- Each device has a unique `clientID` (UUID format)
+- Both devices use the same AWS IoT endpoint
+- Both are configured for production deployment (`PROD`)
+
+## Binary Analysis
+
+### Primary IoT Service Binary
+
+**Location**: `/opt/Bose/IoT`
+- **Type**: ARM ELF 32-bit executable
+- **Purpose**: Main IoT daemon process
+- **Framework**: AWS IoT SDK for C++
+
+### Certificate and Key Management
+
+The IoT binary manages the following certificate files:
+
+| File                  | Location            | Purpose                     |
+|-----------------------|---------------------|-----------------------------|
+| `iot-cert.pem.crt`    | `/mnt/nv/IoTCerts/` | Device client certificate   |
+| `iot-private.pem.key` | `/mnt/nv/IoTCerts/` | Device private key          |
+| `rootCA.crt`          | `/var/lib/iot/`     | AWS IoT Root CA certificate |
+
+### Certificate Registration Process
+
+1. **CSR Generation**: Device generates X.509 certificate signing request
+2. **Registration Endpoint**: `https://voice.api.bose.io/alexa/certificate`
+3. **Certificate Storage**: Certificates stored in `/mnt/nv/IoTCerts/`
+4. **Automatic Provisioning**: Process appears to be automated during device setup
+
+## Protocol Analysis
+
+### Connection Details
+
+- **Protocol**: MQTT over TLS 1.2
+- **Port**: Standard MQTT over SSL (likely 8883)
+- **Authentication**: X.509 client certificate mutual authentication
+- **Endpoint Redundancy**:
+  - Primary (hardcoded): `amqmidtcohfms.iot.us-east-1.amazonaws.com`
+  - Fallback (XML config): `a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com`
+
+### AWS IoT Device Shadow Integration
+
+The system uses AWS IoT Device Shadows for state management:
+
+#### Topic Structure
+```
+$aws/things/{thing_name}/shadow/update
+$aws/things/{thing_name}/shadow/update/accepted
+$aws/things/{thing_name}/shadow/update/rejected
+$aws/things/{thing_name}/shadow/delete
+```
+
+#### Shadow JSON Format
+```json
+{
+  "state": {
+    "desired": {},
+    "reported": {
+      "deviceState": "CONNECTED|DISCONNECTED",
+      "powerState": "ON|OFF",
+      "zoneState": "...",
+      "groupState": "..."
+    }
+  },
+  "version": 0,
+  "clientToken": "...",
+  "timestamp": 0
+}
+```
+
+### Message Types
+
+1. **Device State Updates**
+   - Connection status (`CONNECTED`/`DISCONNECTED`)
+   - Power state changes
+   - Audio zone configuration
+   - Multi-room grouping status
+
+2. **Shadow Delta Processing**
+   - Receives desired state changes
+   - Updates device configuration
+   - Reports new state back to shadow
+
+## System Integration
+
+### Service Management
+
+The IoT service is managed by the Shepherd daemon system:
+
+**Configuration**: `/opt/Bose/etc/Shepherd-noncore.xml`
+```xml
+<ShepherdConfig>
+  <daemon name="STSCertified"/>
+  <daemon name="IoT"/>
+  <daemon name="TPDA">
+    <arg>-c</arg>
+    <arg>/opt/Bose/etc/Voice.xml</arg>
+  </daemon>
+</ShepherdConfig>
+```
+
+### Directory Structure Creation
+
+The SoundTouch init script (`/etc/init.d/SoundTouch`) ensures proper directory structure:
+
+```bash
+mkdir -p /mnt/nv/BoseLog /mnt/nv/IoTCerts /mnt/nv/BoseApp-Persistence/1
+mkdir -m 700 -p /mnt/nv/BoseApp-Persistence/1/Keys
+```
+
+### Process Information
+
+From runtime analysis (`/var/run/shepherd/pids`):
+- IoT service runs as PID 1837
+- BoseApp service runs as PID 1846
+- Both services are active during normal operation
+
+## Configuration Dependencies
+
+### Files That Reference IoT Configuration
+
+1. **IoT Binary** (`/opt/Bose/IoT`)
+   - Primary consumer of IoT.xml configuration
+   - Contains hardcoded backup endpoints
+   - Manages certificate lifecycle
+
+2. **BoseApp Binary** (`/opt/Bose/BoseApp`)
+   - References BoseApp-Persistence directory structure
+   - May trigger IoT updates based on device state changes
+
+3. **SoundTouch Init Script** (`/etc/init.d/SoundTouch`)
+   - Creates necessary directory structure
+   - Ensures proper permissions for certificate storage
+
+4. **Shepherd Configuration** (`/opt/Bose/etc/Shepherd-noncore.xml`)
+   - Defines IoT service startup parameters
+   - Manages service lifecycle
+
+## Security Considerations
+
+### Certificate Management
+- Private keys stored with 700 permissions
+- Certificates managed automatically by the device
+- Registration process appears to use device-specific authentication
+
+### Network Security
+- All communication over TLS 1.2
+- Mutual authentication using X.509 certificates
+- AWS IoT Core provides additional access controls
+
+### Configuration Protection
+- Configuration files stored in persistent storage
+- Directory structure created with appropriate permissions
+- No hardcoded credentials in binaries (uses certificate-based auth)
+
+## Integration Points
+
+### AWS Services
+- **AWS IoT Core**: Primary messaging and device management
+- **AWS IoT Device Management**: Certificate provisioning
+- **AWS IoT Device Shadows**: State synchronization
+
+### Bose Services
+- **Mobile Applications**: Remote control and monitoring
+- **Alexa Integration**: Voice control capabilities
+- **Multi-room Audio**: Zone and group coordination
+
+### Device Functions
+- **Power Management**: Remote power on/off
+- **Audio Control**: Volume, source selection
+- **Network Configuration**: WiFi and connectivity settings
+- **Firmware Updates**: OTA update coordination
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Certificate Problems**
+   - Check `/mnt/nv/IoTCerts/` for valid certificates
+   - Verify certificate registration endpoint accessibility
+   - Ensure proper file permissions (600 for keys)
+
+2. **Connection Issues**
+   - Verify both primary and fallback endpoints
+   - Check TLS 1.2 support and cipher suites
+   - Validate clientID uniqueness
+
+3. **Configuration Issues**
+   - Ensure IoT.xml has proper XML format
+   - Verify clientID is valid UUID format
+   - Check deployment parameter matches environment
+
+### Debug Information
+
+The IoT binary provides extensive logging for:
+- MQTT connection attempts and status
+- Certificate loading and validation
+- Shadow message processing
+- Network state changes
+
+## MQTT Monitoring and Security Considerations
+
+### Direct MQTT Access with Device Credentials
+
+With access to the device's private key and certificate, it's technically possible to subscribe to MQTT events:
+
+```bash
+# Subscribe to device shadow events
+mosquitto_sub -h a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com \
+              -p 8883 --cafile /var/lib/iot/rootCA.crt \
+              --cert /mnt/nv/IoTCerts/iot-cert.pem.crt \
+              --key /mnt/nv/IoTCerts/iot-private.pem.key \
+              -t '$aws/things/_uuid_/shadow/#'
+```
+
+### Security Constraints and Limitations
+
+#### AWS IoT Policy Restrictions
+Device certificates are bound to specific policies that typically restrict:
+- Access to device-specific topics only (`$aws/things/{clientID}/shadow/*`)
+- No wildcard subscriptions across multiple devices
+- Limited publish/subscribe permissions
+- Possible IP geolocation restrictions
+
+#### Example Policy Structure
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": "iot:Connect",
+      "Resource": "arn:aws:iot:us-east-1:*:client/${iot:ClientId}"
+    },
+    {
+      "Effect": "Allow",
+      "Action": ["iot:Publish", "iot:Subscribe", "iot:Receive"],
+      "Resource": [
+        "arn:aws:iot:us-east-1:*:topic/$aws/things/${iot:ClientId}/shadow/*",
+        "arn:aws:iot:us-east-1:*:topicfilter/$aws/things/${iot:ClientId}/shadow/*"
+      ]
+    }
+  ]
+}
+```
+
+#### Additional Security Measures
+- Certificate revocation for unusual activity
+- Device fingerprinting and connection frequency limits
+- Service shutdown timeline (May 2026) affecting endpoint availability
+
+### Alternative Monitoring Approaches
+
+#### Network Traffic Capture
+A less intrusive method to analyze MQTT communication patterns:
+
+```bash
+# Capture encrypted MQTT traffic from the actual device
+tcpdump -i eth0 -s0 -w soundtouch_iot.pcap host a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com
+
+# Monitor connection patterns
+tcpdump -i eth0 -n "host a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com and port 8883"
+```
+
+#### Local MQTT Broker Setup
+For development and testing, create a local MQTT broker that mimics AWS IoT behavior:
+
+```bash
+# Install and configure Mosquitto
+sudo apt-get install mosquitto mosquitto-clients
+
+# Create test shadow topics
+mosquitto_pub -h localhost -t '$aws/things/test-device/shadow/update' \
+              -m '{"state":{"reported":{"deviceState":"CONNECTED"}}}'
+```
+
+### Ethical and Legal Considerations
+
+- **Device Ownership**: Only monitor devices you own
+- **Terms of Service**: Using credentials outside device context may violate Bose ToS
+- **Unauthorized Access**: Accessing Bose's AWS infrastructure could be considered inappropriate
+- **Research Purpose**: Limit monitoring to understanding message formats for local alternatives
+
+### Expected Message Examples
+
+If monitoring is successful, typical shadow messages include:
+
+```json
+// Power state change
+{
+  "state": {
+    "reported": {
+      "powerState": "ON",
+      "deviceState": "CONNECTED",
+      "timestamp": 1703875200
+    }
+  }
+}
+
+// Volume adjustment
+{
+  "state": {
+    "reported": {
+      "volume": 25,
+      "muted": false
+    }
+  }
+}
+
+// Zone configuration
+{
+  "state": {
+    "reported": {
+      "zoneState": "master",
+      "groupMembers": ["device1", "device2"]
+    }
+  }
+}
+```
+
+### Recommended Research Approach
+
+1. **Document Message Formats**: Capture and analyze JSON structures
+2. **Understand State Transitions**: Map device actions to shadow updates
+3. **Build Local Alternative**: Use insights to create local MQTT shadow service
+4. **Prepare for Service Shutdown**: Develop migration strategy before May 2026
+
+## Conclusion
+
+The Bose SoundTouch IoT configuration system is a sophisticated implementation using AWS IoT Core for real-time device management. The system provides:
+
+- Secure, certificate-based authentication
+- Reliable bi-directional communication
+- Comprehensive device state management
+- Integration with voice assistants and mobile applications
+- Robust error handling and retry mechanisms
+
+This architecture enables seamless remote control, monitoring, and coordination of SoundTouch devices across multiple platforms and services.

+# Upstream URLs & Domains Analysis
+
+This document provides a comprehensive overview of the upstream Bose cloud services and domains that SoundTouch devices communicate with. These details were gathered from firmware analysis of ST10/ST20 devices, binary string extraction, and community research from the **SoundCork** project (Issue #128).
+
+## Core Service Domains
+
+SoundTouch devices use a set of primary domains for their operation. These are often configurable via the `SoundTouchSdkPrivateCfg.xml` file.
+
+| Service             | Primary Domain          | Purpose                                                             |
+|:--------------------|:------------------------|:--------------------------------------------------------------------|
+| **Marge**           | `streaming.bose.com`    | Account management, streaming source providers, and preset sync.    |
+| **BMX Registry**    | `content.api.bose.io`   | Bose Media eXchange service discovery and registry.                 |
+| **Stats/Analytics** | `events.api.bosecm.com` | Telemetry, device events, and usage statistics.                     |
+| **Software Update** | `worldwide.bose.com`    | Firmware update checks and downloads (path: `/updates/soundtouch`). |
+| **Voice/Alexa**     | `voice.api.bose.io`     | Token management for Amazon Alexa integration.                      |
+
+## Internal & Development Domains
+
+Analysis of device binaries (`BoseApp`, `IoT`) and community findings revealed several internal, integration, and development domains used by Bose.
+
+### Marge & Auth Proxies
+- `bose-test.apigee.net/margeproxy` (Integration/Test proxy)
+- `bose-test.apigee.net/margeproxyefe`
+- `streamingstg.bose.com` (Staging)
+- `streamingintoauth.bose.com` (Internal Auth)
+- `streamingefeintoauth.bose.com` (Internal EFE Auth)
+- `streamingefeint.bose.com`
+
+### BMX & Content Registry
+- `test.content.api.bose.io`
+- `content.api.bose.io/bmx/registry/v1/services`
+- `test.content.api.bose.io/bmx/int-registry/v1/services`
+- `test.content.api.bose.io/bmx/efe-registry/v1/services`
+
+### Stats & Analytics
+- `eventsdev.api.bosecm.com`
+- `eventsefe.api.bosecm.com`
+- `eventsdev.bosecm.com`
+
+### Software Updates
+- `worldwide.bose.com/updates/soundtouch-int`
+- `worldwide.bose.com/updates/soundtouch-efe`
+
+## Third-Party Services
+
+Devices also communicate directly with third-party providers for specific features.
+
+- **Pandora**: 
+    - `device-tuner.pandora.com`
+    - `device-tuner-beta.savagebeast.com`
+- **Amazon AVS**:
+    - `avs.na.amazonalexa.com`
+
+## Hardcoded Validation (IsItBose)
+
+As documented in [DEVICE-REDIRECT-METHODS.md](DEVICE-REDIRECT-METHODS.md#method-3-binary-patching), the `libBmxAccountHsm.so` library contains a hardcoded regex to validate these URLs:
+
+`^https:\/\/bose-[a-zA-Z0-9\.\_\-\$\%]\+\.apigee\.net\/`
+
+This regex ensures that certain critical services must reside on the `apigee.net` domain under a `bose-` prefix, unless patched.
+
+## Configuration File References
+
+On-device, these URLs are primarily managed in the following files:
+
+1.  **`/opt/Bose/etc/SoundTouchSdkPrivateCfg.xml`**:
+    *   `<margeServerUrl>`
+    *   `<statsServerUrl>`
+    *   `<swUpdateUrl>`
+    *   `<bmxRegistryUrl>`
+2.  **`/opt/Bose/etc/Voice.xml`**:
+    *   `<TPDATokenUrl>` (Points to `voice.api.bose.io`)
+3.  **`/opt/Bose/etc/HandCraftedWebServer-SoundTouch.xml`**:
+    *   Contains internal local API mapping.
+
+## Conclusion for Offline Operation
+
+To achieve full offline operation or redirection to a custom service (like `soundtouch-service`), all of the above domains must either be redirected via DNS (`/etc/hosts`) or updated in the device's XML configuration files. For domains not exposed in XML, binary patching or DNS-level redirection is the only option.

+### Stockholm App Analysis Report
+
+#### 1. Overview
+The Stockholm app is a CEPE MAUI SoundTouch Controller HTML5/JS UI. It is designed to run as a web-based interface for Bose SoundTouch devices, likely served by the device itself or an associated controller.
+
+- **Technology Stack**: HTML5, CSS3, JavaScript (Minified).
+- **Key Libraries**:
+    - **jQuery**: Core DOM manipulation and event handling.
+    - **iScroll**: Used for smooth scrolling in lists and carousels.
+    - **Forge**: Used for cryptographic operations (likely for secure communication or authentication).
+    - **WebSocket Polyfill**: Ensures WebSocket compatibility across environments.
+
+#### 2. Directory Structure
+- `js/`: Core application logic.
+    - `app/`: Main application entry point (`app.js`).
+    - `models/`: Data models for UI components (Presets, Favorites, Onboarding, etc.).
+    - `music_services/`: Implementation of various music services (Amazon, Deezer, Spotify, BMX, etc.).
+    - `views/`: UI view templates and logic.
+    - `utils/`: Utility functions for security, data analytics, and general-purpose tasks.
+- `json/`: Configuration files and static data.
+    - `config.json`: Core application configuration including Base64 encoded Bose API endpoints (e.g., streaming, events, BMX registry).
+    - `sourceFeatures.json`: Capability mapping for different sources.
+- `setup/`: Onboarding and initial device setup logic.
+- `lang/`: Localization files for multi-language support.
+
+#### 3. Communication Architecture
+The app uses several communication channels to interact with the SoundTouch ecosystem:
+
+- **Socket Communication (`socket_comm.js`)**: Real-time updates and low-latency commands via WebSockets.
+- **BMX (`bmx.js` & `js/music_services/bmx/`)**: Interactions with the Bose Music eXperience services. Handles account management, navigation, and API response validation.
+- **Marge (`marge_comm.js`)**: Likely used for interaction with the Marge service (Bose's legacy cloud/proxy service).
+- **Worker-based Architecture**: Many services use Web Workers (`bmx_worker.js`, `spotify_worker.js`) to handle API requests and data processing in the background, keeping the UI responsive.
+
+#### 4. Key Features & Functionality
+- **Multi-Device Management**: Discovering and controlling multiple speakers on the network.
+- **Music Service Integration**: Deep integration with Spotify, Amazon Music, Deezer, and Pandora.
+- **Preset Management**: Browsing and setting presets directly from the UI.
+- **Zone Control**: Creating and managing multi-room groups (Master/Slave configurations).
+- **Onboarding**: A dedicated setup flow for new devices.
+- **Analytics & Data Collection**: Modules like `data_analytics.js` and `dc_server.js` suggest tracking of user interactions.
+
+#### 5. Integration Opportunities for Bose-SoundTouch Project
+Based on the Stockholm app's capabilities, the following features could be enhanced or added to our Go-based `soundtouch-service`:
+
+1.  **Enhanced BMX Emulation**: Use insights from `bmx_client.js` and `bmx_navigate_response_generator.js` to improve our local BMX implementation.
+2.  **Spotify/Amazon Service Proxies**: Implement the backend logic required to support the same API calls the Stockholm app makes to these services.
+3.  **UI parity**: The Stockholm app's view templates (`views/`) can serve as a reference for our Web Management UI.
+4.  **WebSocket Support**: Ensure our service provides a robust WebSocket interface similar to what the Stockholm app expects for real-time state synchronization.
+5.  **Capability Discovery**: Better utilization of the `sourceFeatures.json` logic to dynamically show/hide features based on the device model and firmware version.
+
+#### 6. Conclusion
+The Stockholm app is a mature, full-featured controller that relies heavily on Bose's proprietary BMX and Marge services. By analyzing its client-side logic, we can better understand the expected API responses and interaction patterns needed to provide a seamless local replacement for the Bose Cloud.

+# Merging Bose-SoundTouch-API into Bose-SoundTouch
+
+This document outlines the plan to merge the [Bose-SoundTouch-API](https://github.com/gesellix/Bose-SoundTouch-API) project into this repository. The actual Go implementation in that repository is located in the `soundcork-go` subdirectory. The goal is to provide both a CLI (`soundtouch-cli`) and a service (`soundtouch-service`) from a single codebase.
+
+## Goals
+
+- [x] Maintain the existing `soundtouch-cli` functionality.
+- [x] Introduce `soundtouch-service` as a new command (based on the `soundcork-go` project).
+- [x] Consolidate shared logic (models, clients, discovery) into the `pkg/` directory.
+- [x] Simplify maintenance by having a single Go module and shared CI/CD pipeline.
+

+```
+
+## Step-by-Step Merge Status
+
+### 1. Preparation
+- [x] Review `go.mod` in both projects to identify dependency overlaps and conflicts.
+
+### 2. Code Integration
+- [x] **Models & Client**: Merged missing functionality from `soundcork-go/internal/models` into `pkg/models`. Renamed overlapping models to `Service*` (e.g., `ServiceContentItem`, `ServicePreset`).
+- [x] **Service Logic**: Adapted internal packages from `soundcork-go/internal/` to `pkg/service/`.
+- [x] **Handlers**: Moved and adapted HTTP handlers into `pkg/service/handlers/`.
+- [x] **New Command**: Created `cmd/soundtouch-service/main.go` as the service entry point using `chi` router.
+- [x] **Embedded Resources**: Integrated `index.html`, `bmx_services.json`, `swupdate.xml`, and `media/` folder into the binary using `//go:embed`.
+
+### 3. Dependency Management
+- [x] Update `go.mod` to include:
+    - `github.com/go-chi/chi/v5`
+    - `github.com/srwiley/oksvg` and `github.com/srwiley/rasterx`
+    - `golang.org/x/crypto`
+- [x] Run `go mod tidy` to clean up dependencies.
+
+### 4. Shared Logic Refactoring
+- [x] Identify common code between `soundtouch-cli` and the new service.
+- [x] Move shared logic into `pkg/` to ensure both commands use the same underlying implementation.
+
+### 5. Documentation & Examples
+- [x] Update `README.md` to mention the new `soundtouch-service` command.
+- [x] Add service-specific documentation in `docs/SOUNDTOUCH-SERVICE.md`.
+- [x] Provide examples of how to run and interact with the service in `examples/service-demo/`.
+
+### 6. CI/CD Updates
+- [x] Update `.github/workflows/release.yml` to build and release the `soundtouch-service` binary alongside `soundtouch-cli`.
+- [x] Update any test workflows to include tests for the service logic.
+
+## Verification
+- [x] `go build ./cmd/soundtouch-cli` works as expected.
+- [x] `go build ./cmd/soundtouch-service` works as expected.
+- [x] All tests pass: `go test ./...`.
+- [x] Resources are correctly served from the embedded filesystem.

+# Upstream Bose Service Simulation - Concept Overview
+
+## Executive Summary
+
+This document serves as the entry point for understanding the comprehensive plan to enhance the SoundTouch service with advanced state management capabilities, preparing for the eventual shutdown of Bose's upstream services while providing a superior local management experience.
+
+## Project Objectives
+
+### Primary Goal
+Create a robust, local replacement for Bose's upstream services that can seamlessly handle the transition from cloud-dependent to fully autonomous operation while maintaining and improving upon the existing functionality.
+
+### Key Outcomes
+- **Zero-downtime transition** from Bose services to local management
+- **Enhanced visibility** into device states, health, and system operations
+- **Data preservation** during migrations with full rollback capabilities
+- **Improved reliability** through local control and reduced external dependencies
+- **Future-proof architecture** that can evolve beyond Bose's original design
+
+## Architecture Vision
+
+### Current State
+The existing SoundTouch service provides:
+- BMX service for TuneIn integration
+- Marge service for account and device management  
+- Basic mirroring of upstream Bose endpoints
+- File-based persistence for device data
+- Migration support for device directory structures
+
+### Enhanced State (This Project)
+The enhanced system will add:
+- **Comprehensive Account Management** with explicit creation and migration tracking
+- **Device Lifecycle Management** with full state machine and event processing
+- **Advanced Mirroring** with disparity detection and analysis
+- **Dual-Source Data Management** supporting gradual migration strategies
+- **Real-time Monitoring** with health checks and performance metrics
+- **Text-based Storage** optimized for debugging and small hardware deployments
+
+## Use Case Coverage
+
+### Case 0: Account Management
+- **Explicit Account Creation**: Accounts created through deliberate user action
+- **Mirror-Enhanced Setup**: Use upstream data to enrich account creation
+- **Passive Data Collection**: Record account information during normal operations
+
+### Case 1a: Fresh Device Registration  
+- **Factory Reset Support**: Handle devices with no prior Bose association
+- **Default Configuration**: Initialize devices with sensible presets and sources
+- **Local-First Setup**: Complete registration without upstream dependencies
+
+### Case 1b: Bose Account Migration
+- **Data Preservation**: Maintain existing presets, recents, and sources
+- **Gradual Migration**: Support partial migration while maintaining upstream compatibility
+- **Rollback Capability**: Revert to Bose services if needed
+
+### Case 2: Lifecycle and State Management
+- **Real-time State Tracking**: Monitor device states and health continuously
+- **Event-Driven Updates**: Process device events asynchronously
+- **Disparity Detection**: Identify differences between local and upstream behavior
+- **Comprehensive Logging**: Maintain detailed audit trails for troubleshooting
+
+## Technical Approach
+
+### Design Principles
+1. **Text-First Storage**: Human-readable formats (JSON, XML, logs) for easy debugging
+2. **Small Hardware Optimization**: Designed for Raspberry Pi Zero 2W deployments
+3. **Mirror-First Strategy**: Keep upstream mirroring active until migration complete
+4. **Event-Driven Architecture**: Asynchronous processing with comprehensive event tracking
+5. **Backward Compatibility**: Seamless integration with existing installations

+The SoundTouch service supports Spotify OAuth integration to broker access tokens for SoundTouch speakers. This is particularly useful for maintaining Spotify Connect functionality after the Bose cloud shutdown (scheduled for May 2026).
+
+## OAuth Flows
+
+The service supports two primary OAuth flows: a browser-based flow and a mobile app-based flow (specifically for the [ueberboese](https://github.com/julius-d/ueberboese-app) app).
+
+### 1. Browser-based Flow
+
+The user initiates the flow, completes authorization in their browser, and is redirected back to the service.
+
+```mermaid
+sequenceDiagram
+    participant Client as Client (curl/app)
+    participant Service as Service
+    participant Spotify as Spotify Auth Server
+    participant Browser as User's Browser
+
+    Client->>Service: POST /mgmt/spotify/init [Basic Auth]
+    Service-->>Client: {"redirectUrl": "https://accounts.spotify.com/authorize?..."}
+    
+    Client->>Browser: User opens URL
+    Browser->>Spotify: User logs in & grants access
+    Spotify-->>Browser: Redirect to /mgmt/spotify/callback?code=abc
+    
+    Browser->>Service: GET /mgmt/spotify/callback?code=abc
+    Note over Service: No auth needed for callback
+    
+    Service->>Spotify: POST /api/token (exchange code)
+    Spotify-->>Service: {access_token, refresh_token}
+    
+    Service->>Spotify: GET /v1/me (fetch profile)
+    Spotify-->>Service: {id, display_name, email}
+    
+    Note over Service: Store account to disk
+    
+    Service-->>Browser: HTML: "Spotify Connected. You can close this window."
+```
+
+### 2. Mobile App Flow (ueberboese)
+
+The mobile app handles the redirect via a deep link and then confirms the authorization with the service.
+
+```mermaid
+sequenceDiagram
+    participant App as ueberboese Flutter App
+    participant Service as Service
+    participant Spotify as Spotify Auth Server
+
+    App->>Service: POST /mgmt/spotify/init [Basic Auth]
+    Service-->>App: {"redirectUrl": "https://..."}
+    
+    App->>Spotify: Open in-app browser (User authorizes)
+    Spotify-->>App: Deep link redirect: ueberboese-login://spotify?code=abc
+    
+    App->>Service: POST /mgmt/spotify/confirm?code=abc [Basic Auth]
+    
+    Service->>Spotify: POST /api/token (exchange code)
+    Spotify-->>Service: {access_token, refresh_token}
+    
+    Service->>Spotify: GET /v1/me (fetch profile)
+    Spotify-->>Service: {profile}
+    
+    Service-->>App: {"ok": true}
+```
+
+### 3. Token Retrieval (Boot Primer / Speaker Setup)
+
+Once an account is linked, access tokens can be retrieved for use with speakers (e.g., via the `addUser` ZeroConf command).
+
+```mermaid
+sequenceDiagram
+    participant Primer as Boot Primer Script
+    participant Service as Service
+    participant Spotify as Spotify Token API
+    participant Speaker as Speaker (Bose ST 20)
+
+    Primer->>Service: GET /mgmt/spotify/token [Basic Auth]
+    
+    alt Token expired
+        Service->>Spotify: POST /api/token (refresh)
+        Spotify-->>Service: new tokens
+    end
+    
+    Service-->>Primer: {"access_token": "...", "username": "..."}
+    
+    Note over Primer: Spotify Connect ZeroConf
+    Primer->>Speaker: POST /SpotifyConnect (addUser with token)
+    Speaker-->>Primer: OK
+    Note over Speaker: Speaker now has Spotify access
+```
+
+## Boot Primer Script
+
+A boot primer script that uses these endpoints to feed Spotify tokens to speakers via ZeroConf is available in the `scripts/spotify/` directory: [spotify-boot-primer.sh](../../scripts/spotify/spotify-boot-primer.sh).
+
+This script can be installed on the speaker itself (which runs embedded Linux) to automatically prime Spotify Connect at boot time. See [README.md](../../scripts/spotify/README.md) and [INSTALL.md](../../scripts/spotify/INSTALL.md) for instructions.
+
+### Automated Installation via Service
+
+The SoundTouch service provides a dedicated management endpoint to automatically handle the installation of the Spotify boot primer on the speaker:
+`POST /mgmt/devices/{deviceId}/spotify/install-primer`
+
+### Automated Installation Steps
+When you run the Spotify primer installation, the service performs the following:
+1.  **Directories**: Creates `/mnt/nv/bin` and `/mnt/nv/BoseApp-Persistence/1` on the speaker.
+2.  **Binary**: Uploads the `spotify-boot-primer` script to the speaker.
+3.  **Configuration**: Automatically generates and uploads `spotify-primer.conf` containing the service's URL and management credentials.
+4.  **Boot Hook**: Injects a call to the primer in the speaker's `/mnt/nv/rc.local` using idempotent markers.
+5.  **Environment**: Updates `/mnt/nv/.profile` to include `/mnt/nv/bin` in the `PATH` for easier manual troubleshooting via SSH.
+
+- **Idempotent Patching**: The service uses explicit markers to inject the hook, ensuring it doesn't corrupt existing content.
+- **Coexistence**: The service-injected hook is designed to coexist with a manually installed `rc.local` (e.g., from the community gist). It only adds a call to `/mnt/nv/bin/spotify-boot-primer` if it's not already managed by a service-controlled block.
+- **Markers**: Look for the following markers in your speaker's `/mnt/nv/rc.local`:
+  - `# --- Aftertouch Spotify hook START ---`
+  - `# --- Aftertouch Spotify hook END ---`
+- **Cleanup**: Reverting a migration via the service will cleanly remove these marker-delimited blocks.

+
+## Security
+
+- `/mgmt/spotify/callback` is intentionally outside Basic Auth to allow direct redirects from Spotify's authorization server.
+- All other `/mgmt/*` endpoints require Basic Auth as configured by `--mgmt-username` and `--mgmt-password`.
+- Tokens are persisted to disk as JSON with restricted file permissions (`0600`).
+- The `GetAccounts` endpoint strips sensitive tokens from the response.

+# Spotify Priming Strategy
+
+This document outlines the strategy for ensuring Bose SoundTouch devices are correctly "primed" for Spotify Connect integration within the AfterTouch ecosystem.
+
+## 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.
+
+AfterTouch adopts a **Server-Centric Hybrid Model** that prioritizes device cleanliness and user intent while providing automated self-healing.
+
+## Core Principles
+
+### 1. User Intent (Opt-in)
+AfterTouch replicates the native Bose "Add Source" experience. No Spotify priming occurs until a user explicitly links their Spotify account through the AfterTouch Management Dashboard. This ensures privacy and respects users who do not wish to use Spotify.
+
+### 2. Device Cleanliness (Minimalist Footprint)
+We avoid invasive modifications to the speaker's filesystem. 
+- **No On-Device Scripts:** We deprecate the use of internal boot-primer scripts.
+- **Native Communication:** We rely on the speaker's native ability to talk to Bose services, which are intercepted via DNS to point to the AfterTouch server.
+
+### 3. Triggers for Priming
+Priming is triggered when the speaker signals it is active and ready, specifically:
+
+- **Power On:** When the speaker calls the `/marge/streaming/support/power_on` endpoint, AfterTouch ensures the device's ZeroConf state is correctly primed. This is the primary trigger.
+- **Manual Override:** Users can manually trigger a "Prime Spotify" from the device list in the UI if needed.
+
+During any of these events, the server:
+1. Checks if a Spotify account is linked in AfterTouch.
+2. Checks the device's current priming status (via ZeroConf).
+3. If unprimed and an account is linked, it pushes the priming command.
+
+### 4. Automated Recovery
+AfterTouch ensures that if a speaker loses its session (due to a crash or power loss), it is re-primed when it next powers on and reaches out to the service.
+
+### 5. Decoupling
+The logic for account management and device interaction remains decoupled:
+- **Spotify Service:** Manages OAuth tokens and account state.
+- **Discovery Service:** Finds devices and tracks their network presence.
+- **Orchestrator:** Connects the two, deciding when to push tokens to discovered devices based on the current link status.
+
+## Workflow
+
+### Initial Setup (The "Add Source" UX)
+1. User opens the AfterTouch Dashboard.
+2. User selects "Link Spotify Account."
+3. OAuth flow completes; AfterTouch stores the token.
+4. AfterTouch immediately triggers a discovery run to find and prime all compatible speakers.
+
+### Maintenance (The "Watchdog" UX)
+1. A speaker reboots or loses its token.
+2. A discovery event occurs (periodic or triggered by UI).
+3. AfterTouch detects the "Empty" user state on the speaker.
+4. AfterTouch pushes a fresh token from the Spotify Service.
+5. UI reflects that the device is "Managed by AfterTouch" and healthy.
+
+### Manual Override
+Users can manually trigger a "Re-prime" or "Refresh Link" from the device list in the UI if they suspect the automated self-healing is delayed or if they want to force a specific account onto a device.
+
+## Network Topology & Deployment Scenarios
+
+The strategy adapts based on where the AfterTouch server is deployed:
+
+### Local Deployment (Home Server / Docker)
+- **Mechanism:** Both "Pull" (Marge) and "Push" (ZeroConf side-channel) are used.
+- **Advantage:** The server can proactively fix the speaker's state via port 8200 as soon as it sees a "Liveness Signal."
+
+### External Deployment (Cloud VPS)
+- **Mechanism:** Primarily relies on "Pull" (Marge).
+- **Constraint:** The server cannot reach port 8200 on the speaker due to NAT/Firewall.
+- **Strategy:** In this scenario, AfterTouch acts as a passive token provider. The speaker must initiate the connection to our intercepted Bose endpoints to receive its Spotify configuration. If the speaker completely loses its user state and stops "pulling," a manual re-prime from a local machine or a temporary local discovery run might be required.
+
+## Transition & Cleanup
+
+As AfterTouch moves to the Server-Centric model, we will:
+1.  **Revert On-Device Migration:** Update the Setup Manager to remove legacy `spotify-boot-primer` scripts and `rc.local` hooks from the speakers.
+2.  **Consolidated Directory:** We maintain the `/mnt/nv/soundtouch-service/` base directory for other configuration needs (e.g., `aftertouch.resolv.conf`), but it will no longer contain Spotify-specific credentials or scripts.
+3.  **No On-Device Credentials:** The `/mnt/nv/soundtouch-service/spotify-primer.conf` will be removed, ensuring that no sensitive AfterTouch login details are stored on the speaker in plain text.
+
+## Implementation Roadmap (Conceptual)
+
+1. **Revert On-Device Migration:** Update the Setup Manager to remove legacy scripts and `rc.local` hooks.
+2. **Server-Side Priming Logic:** Implement a `PrimeDevice(ip)` method in the server that fetches a fresh token and calls the ZeroConf API.
+3. **Discovery Hook:** Integrate `PrimeDevice` into the discovery handler (`handleDiscoveredDevice`) with a check for unprimed state.
+4. **UI Enhancements:** Update the Speaker List to show "Spotify Linked" status and provide manual refresh buttons.

+Registering → Active (via successful registration)
+Registering → Error (via registration failure)
+Active → Migrating (via migration start)
+Active → Offline (via connectivity loss)
+Migrating → Active (via migration success)
+Migrating → Error (via migration failure)
+Offline → Active (via connectivity restored)

+
+### Development Requirements
+
+#### KISS Principle (Keep It Simple, Stupid)
+- Prioritize simplicity and readability over performance optimization
+- Use standard Go idioms and patterns
+- Avoid premature abstraction and optimization
+- Build the simplest thing that works first
+
+#### Quality Gates
+Every change must pass these checks:
+- `golangci-lint run --fix` - no linting issues
+- `go test ./...` - all tests pass with no failures
+- Integration tests verify existing functionality intact
+- Code coverage maintained or improved
+
+#### Testing Requirements
+- Unit tests for all new functions
+- Integration tests for modified workflows
+- Regression tests for existing functionality
+- Mock external dependencies appropriately
+
+### Simplicity-First Performance Approach
+
+| Aspect | Simple Approach | Optimization Only When Needed |
+|--------|----------------|-------------------------------|
+| Memory Usage | Direct file operations, minimal caching | Add caching if performance issues arise |
+| CPU Usage | Synchronous processing initially | Add async processing if bottlenecks occur |
+| Storage | Simple append operations | Add rotation/compression when files grow large |
+| Networking | Reuse existing patterns | Optimize only if latency becomes problematic |
+
+## Quality Assurance
+
+### Testing Strategy
+
+#### Unit Testing
+```go
+// Example test structure
+func TestAccountManager_CreateAccount(t *testing.T) {
+    tests := []struct {
+        name    string
+        input   CreateAccountRequest
+        want    *Account
+        wantErr bool
+    }{
+        {
+            name: "valid account creation",
+            input: CreateAccountRequest{Name: "Test Account"},
+            want: &Account{Name: "Test Account", Status: "active"},
+            wantErr: false,
+        },
+        {
+            name: "empty name should fail",
+            input: CreateAccountRequest{Name: ""},
+            want: nil,
+            wantErr: true,
+        },
+    }
+    
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            got, err := manager.CreateAccount(tt.input)
+            if (err != nil) != tt.wantErr {
+                t.Errorf("CreateAccount() error = %v, wantErr %v", err, tt.wantErr)
+                return
+            }
+            // Additional assertions...
+        })
+    }
+}
+```
+
+#### Integration Testing
+- Test with real file operations in temporary directories
+- Verify HTTP endpoints work with actual HTTP requests
+- Test interaction with existing WebSocket system
+- Ensure existing XML endpoints remain functional
+
+#### Quality Gates
+```bash
+# Required before each commit
+golangci-lint run --fix
+go test ./...
+go test -race ./...
+
+# Required before milestone completion
+go test ./... -v -cover
+go test -bench=. ./...
+```
+
+### Security Considerations
+
+#### Simple Security Model
+- Reuse existing authentication mechanisms
+- Basic input validation with standard Go validation
+- Simple file permissions (0755 for directories, 0644 for files)
+- No complex authorization initially - build incrementally
+
+#### Input Validation
+```go
+// Simple validation approach
+func ValidateAccount(account *Account) error {
+    if account.Name == "" {
+        return errors.New("account name cannot be empty")
+    }
+    if len(account.Name) > 100 {
+        return errors.New("account name too long")
+    }
+    if account.Email != "" && !isValidEmail(account.Email) {
+        return errors.New("invalid email format")
+    }
+    return nil
+}
+```
+
+## Error Handling
+
+### Error Categories
+
+```go
+type ErrorCategory string
+const (
+    ErrorCategoryValidation ErrorCategory = "validation"
+    ErrorCategorySystem     ErrorCategory = "system"
+    ErrorCategoryNetwork    ErrorCategory = "network"
+    ErrorCategoryStorage    ErrorCategory = "storage"
+    ErrorCategoryTimeout    ErrorCategory = "timeout"
+    ErrorCategoryAuth       ErrorCategory = "authentication"
+)
+
+type ServiceError struct {
+    Code        string                 `json:"code"`
+    Message     string                 `json:"message"`
+    Category    ErrorCategory          `json:"category"`
+    Timestamp   time.Time              `json:"timestamp"`
+    Context     map[string]interface{} `json:"context"`
+    Retryable   bool                   `json:"retryable"`
+    Severity    string                 `json:"severity"`
+}
+```
+
+### Error Recovery Strategies
+
+1. **Transient Errors**: Exponential backoff retry (3 attempts)
+2. **Storage Errors**: Graceful degradation with in-memory fallback
+3. **Network Errors**: Circuit breaker pattern with fallback data
+4. **Validation Errors**: Immediate response with detailed feedback
+5. **System Errors**: Alerting and automatic recovery attempts
+
+### Error Response Format
+
+```json
+{
+  "error": {
+    "code": "DEVICE_NOT_FOUND",
+    "message": "Device with ID 'A81B6A536A98' not found in account 'acc_12345'",
+    "category": "validation",
+    "timestamp": "2024-01-20T15:30:00Z",
+    "context": {
+      "account_id": "acc_12345",
+      "device_id": "A81B6A536A98",
+      "request_id": "req_67890"
+    },
+    "retryable": false,
+    "severity": "error"
+  },
+  "request_id": "req_67890"
+}
+```
+
+## Monitoring and Observability
+
+### Simple Monitoring Approach
+
+#### Basic Health Check
+```go
+// Simple health check implementation
+type HealthStatus struct {
+    Status    string    `json:"status"`    // "healthy", "warning", "error"
+    Timestamp time.Time `json:"timestamp"`
+    Version   string    `json:"version"`
+    Uptime    string    `json:"uptime"`
+}
+
+func (s *Server) HandleHealthCheck(w http.ResponseWriter, r *http.Request) {
+    health := HealthStatus{
+        Status:    "healthy",
+        Timestamp: time.Now(),
+        Version:   version,
+        Uptime:    time.Since(startTime).String(),
+    }
+    
+    // Simple checks
+    if !s.canWriteToDataDir() {
+        health.Status = "error"
+    }
+    
+    w.Header().Set("Content-Type", "application/json")
+    json.NewEncoder(w).Encode(health)
+}
+```
+
+#### Leverage Existing Systems
+- Extend existing parity mismatch logging for disparity detection
+- Reuse existing interaction recording for request/response tracking
+- Build upon current discovery and migration event logging
+- Use existing WebSocket event system for device state changes
+
+#### Simple Metrics
+```go
+// Basic counters - no complex metrics initially
+type SimpleMetrics struct {
+    AccountsCreated   int `json:"accounts_created"`
+    DevicesActive     int `json:"devices_active"`
+    EventsProcessed   int `json:"events_processed_today"`
+    LastUpdate        time.Time `json:"last_update"`
+}
+
+// Update metrics in simple text file
+func (m *SimpleMetrics) Save(dataDir string) error {
+    data, err := json.MarshalIndent(m, "", "  ")
+    if err != nil {
+        return err
+    }
+    return os.WriteFile(filepath.Join(dataDir, "metrics.json"), data, 0644)
+}
+```

+# Upstream Bose Service Simulation - State Management Concept
+
+## Overview
+
+This document outlines the concept for simulating and replacing upstream Bose services with enhanced state management capabilities. The goal is to create a comprehensive local replacement that can handle device lifecycles, account management, and state synchronization while maintaining compatibility with existing SoundTouch devices.
+
+## Use Cases
+
+### Case 0: Account Management
+- **Explicit Account Creation**: Accounts must be created through deliberate action (web UI, API call)
+- **Mirror-Enhanced Creation**: Account creation can be enriched using mirrored data from upstream Bose endpoints when devices make requests
+- **Data Recording**: Passively record account information during normal device operations for future use
+
+### Case 1a: Fresh Device Registration
+- Initial setup/registration of a factory-reset or new device
+- Device has no prior Bose account association
+- Full local initialization with default configurations
+
+### Case 1b: Device Migration from Bose Account
+- Migrate existing registered device from Bose services to local management
+- Preserve existing device data (presets, recents, sources)
+- Support gradual migration while maintaining Bose compatibility
+- Mirror Bose account data for seamless transition
+
+### Case 2: Device Lifecycle and State Management
+- Track and manage device lifecycle states and activities
+- Maintain internal state based on incoming events from devices
+- Detect disparities between local and upstream behavior
+- Provide visibility into state changes and system health
+
+## Architecture Principles
+
+### 1. **Text-Based Storage for Debugging**
+- Maintain all state in human-readable text formats (XML, JSON, plain text)
+- Use small, focused files for each data aspect
+- Enable easy debugging and manual inspection
+- Optimize for small hardware deployments (Raspberry Pi Zero 2W)
+
+### 2. **Mirror-First Strategy**
+- Keep mirror functionality active as long as possible
+- Primary source switches from upstream to local only during:
+  - Explicit migration
+  - Sufficient local data accumulation
+  - Upstream service unavailability
+- Record and mirror as much data as possible, even if not immediately used
+
+### 3. **Disparity Detection**
+- Track differences between local and upstream responses
+- Log discrepancies for analysis and improvement
+- Provide visibility into implementation gaps
+- Support parity testing and validation
+
+### 4. **Event-Driven State Management**
+- Process device events asynchronously
+- Track comprehensive event history in text files
+- Support event replay and analysis
+- Minimize noise while capturing important state changes
+

+- Avoid premature abstraction and optimization
+- Build the simplest thing that works first
+
+### Quality First
+- Every milestone must pass `golangci-lint run --fix` without issues
+- Complete test suite must pass `go test ./...` before proceeding
+- Integration tests ensure existing functionality remains intact
+- Code coverage should be maintained or improved
+
+### Incremental Development
+- Make small, focused changes that can be easily reviewed

+# Device Lifecycle and /power_on Enhancement
+
+## Overview
+
+This document provides a comprehensive analysis of the current SoundTouch device registration and lifecycle management implementation, and proposes enhancements using the `/power_on` endpoint to reduce dependency on local network connectivity.
+
+## Current Implementation Assessment
+
+### Device Information Sources
+
+The current system uses multiple data collection methods to build a complete device profile:
+
+#### 1. UPnP/SSDP Discovery
+- **Protocol**: Multicast UDP discovery for `urn:schemas-upnp-org:service:SoundTouch:1`
+- **Network Scope**: Limited to same network segment
+- **Data Collected**:
+  ```go
+  type DiscoveredDevice struct {
+      Name            string    // From UPnP friendlyName
+      Host            string    // IP address
+      Port            int       // Usually 8090
+      ModelID         string    // From UPnP modelName  
+      SerialNo        string    // MAC address from UPnP
+      UPnPLocation    string    // Device description URL
+      UPnPUSN         string    // Unique service name
+  }
+  ```
+
+#### 2. mDNS/Bonjour Discovery
+- **Protocol**: Multicast DNS for `_soundtouch._tcp` services
+- **Network Scope**: Limited to same network segment
+- **Purpose**: Complements UPnP discovery with hostname resolution
+
+#### 3. `/info` Endpoint Enrichment
+- **Protocol**: HTTP GET to `http://device:8090/info`
+- **Network Scope**: Requires direct connectivity to device
+- **Data Collected**:
+  ```xml
+  <info deviceID="ABCD1234EFGH">
+      <name>My SoundTouch Device</name>
+      <type>SoundTouch 10</type>
+      <margeAccountUUID>3230304</margeAccountUUID>

+
+### Device Registration Points
+
+The system has distinct phases where device information is collected and enhanced:
+
+#### Phase 1: Discovery (Network-Dependent)
+**Trigger**: Automatic network scanning
+**Data Sources**: UPnP + mDNS + `/info` endpoint
+**Limitations**: ❌ Requires same network segment
+
+#### Phase 2: User Registration (User-Controlled)
+**Trigger**: User adds device to account
+**Endpoint**: `POST /streaming/account/{accountId}/devices`
+**Request Format**:
+```xml
+<device deviceid="08DF1F0BA325">
+    <name>Living Room Speaker</name>
+</device>
+```
+**Data Added**: ✅ User-friendly name, Account association
+
+#### Phase 3: Ongoing Updates (Mixed)
+**Triggers**: Device state changes, firmware updates, network changes
+**Methods**: Periodic `/info` polling, Discovery refresh, User configuration
+
+### Current Data Model
+
+The system maintains comprehensive device information:
+
+```go
+type ServiceDeviceInfo struct {
+    DeviceID            string `json:"device_id"`           // MAC or UUID
+    Name                string `json:"name"`                // User-friendly name
+    ProductCode         string `json:"product_code"`        // Device model
+    DeviceSerialNumber  string `json:"device_serial_number"` // Hardware serial
+    ProductSerialNumber string `json:"product_serial_number"` // Product serial
+    FirmwareVersion     string `json:"firmware_version"`     // Software version
+    IPAddress           string `json:"ip_address"`           // Current IP
+    MacAddress          string `json:"mac_address"`          // MAC address
+    AccountID           string `json:"account_id"`           // Account association
+    DiscoveryMethod     string `json:"discovery_method"`     // How discovered
+}
+```
+
+## Limitations of Current Approach
+
+### Network Dependency Issues
+
+| Issue | Impact | Affected Operations |
+|-------|--------|-------------------|
+| **Same Network Requirement** | High | Device discovery, Initial setup |
+| **Direct Connectivity Need** | High | Device enrichment, Migration |
+| **Firewall/NAT Restrictions** | Medium | Corporate networks, Complex setups |

+
+### Implementation Strategy
+
+#### Phase 1: Hybrid Approach
+Implement `/power_on` processing while maintaining existing discovery methods:
+
+```go
+func (s *Server) HandleMargePowerOn(w http.ResponseWriter, r *http.Request) {
+    // Parse power_on request
+    var powerOnData models.CustomerSupportRequest
+    if err := xml.Unmarshal(body, &powerOnData); err != nil {
+        // Fallback to existing discovery
+        return s.fallbackToDiscovery(r.RemoteAddr)
+    }
+    
+    // Extract device information
+    deviceMAC := powerOnData.Device.ID
+    deviceIP := powerOnData.DiagnosticData.DeviceLandscape.IPAddress
+    
+    // Lookup existing device data
+    deviceInfo := s.lookupDeviceByMAC(deviceMAC)
+    if deviceInfo == nil {
+        // New device - trigger registration flow
+        deviceInfo = s.createDeviceFromPowerOn(powerOnData)
+    }
+    
+    // Update with power_on data
+    s.updateDeviceFromPowerOn(deviceInfo, powerOnData)
+    
+    // Determine response actions
+    response := s.buildPowerOnResponse(deviceInfo)
+    s.sendResponse(w, response)
+}
+```
+
+#### Phase 2: Gap Resolution
+Address missing data through complementary mechanisms:
+
+1. **User-Friendly Names**: Maintain registration process for name assignment
+2. **Account Association**: Enhance registration to link MAC addresses to accounts
+3. **Service URLs**: Implement account-based service URL resolution
+4. **Regional Settings**: Use IP geolocation or account preferences
+
+#### Phase 3: Enhanced Device Lifecycle

+```
+
+### Migration Strategy
+
+#### Current Migration Flow Issues
+- Requires `/info` endpoint access for device identification
+- Must be on same network for configuration changes
+- Limited to devices discoverable via UPnP/mDNS
+
+#### Enhanced Migration with /power_on
+
+1. **Device Identification**: Use MAC address from `/power_on` instead of IP-based `/info`
+2. **Configuration Delivery**: Send migration instructions in `/power_on` response
+3. **Status Confirmation**: Device confirms changes via subsequent `/power_on` requests
+4. **Remote Capability**: Manage devices from any network location
+
+```go
+type PowerOnResponse struct {
+    ConfigurationUpdates []ConfigUpdate `json:"configuration_updates,omitempty"`
+    MigrationInstructions *Migration    `json:"migration,omitempty"`
+    RegistrationRequired  bool          `json:"registration_required,omitempty"`
+}
+
+type Migration struct {
+    Method      string            `json:"method"`       // xml, hosts, resolv_conf
+    TargetURL   string           `json:"target_url"`
+    ProxyURL    string           `json:"proxy_url,omitempty"`
+    Options     map[string]string `json:"options"`
+}
+```
+
+## Recommendations
+
+### Immediate Actions (Phase 1)
+1. **Enhance `/power_on` handler** to extract and store comprehensive device data
+2. **Implement device lookup by MAC address** as primary identification method  
+3. **Create hybrid discovery system** using both `/power_on` and existing methods

+2. **Implement real-time device monitoring** via `/power_on` events  
+3. **Create centralized device management** independent of network topology
+4. **Add predictive migration** based on device status patterns
+
+### Risk Mitigation
+- **Maintain backward compatibility** with existing discovery methods
+- **Implement graceful fallbacks** when `/power_on` data is incomplete

+# SoundTouch Device Initial Setup Variants
+
+Based on community research from the **SoundCork** and **ÜberBöse API** projects, as well as analysis of the Stockholm firmware (`firmware/Stockholm/.../setup/`), this document outlines the methods used for the "out-of-the-box" setup of SoundTouch devices.
+
+## Setup Overview
+
+Initial setup is the process of connecting a new or factory-reset device to a local Wi-Fi network and a Bose (or custom) account. This is distinct from the "Migration" process (handled by `soundtouch-service`), which redirects an already-configured device to a new server.
+
+---
+
+## 1. Bluetooth Low Energy (BLE) Setup
+Used by most modern SoundTouch devices (ST-10, ST-20/30 Series III, SoundTouch 300).
+
+- **Mechanism**: The SoundTouch app communicates with the device over BLE to exchange Wi-Fi credentials.
+- **Protocol**: Internal research refers to this as the **Gabbo** protocol (see `gabbo_setup_bco.js` in firmware).
+- **Process**:
+  1. Put the device in setup mode (usually by holding the '2' and '-' buttons).
+  2. The app discovers the device via BLE.
+  3. The app sends the Wi-Fi SSID and Password to the device.
+  4. The device connects to Wi-Fi and disables BLE setup.
+
+---
+
+## 2. Access Point (AP) Mode / Web Setup
+The classic "failover" or "alternate" setup method.
+
+- **Mechanism**: The device creates its own Wi-Fi network (SSID: `Bose SoundTouch ...` or `Bose Home Speaker ...`).
+- **IP Address**: Typically `192.168.1.1` or `10.0.0.1` (device-side).
+- **Web Interface**: The device hosts a web server on port 80.
+- **Process**:
+  1. Connect a PC/Phone to the device's Wi-Fi.
+  2. Open a browser to `http://192.168.1.1`.
+  3. The device serves `setup.html`, which redirects to a setup wizard (`setup/index.html`).
+  4. Use the `gabbo_wifi` form to select a network and enter credentials.
+
+---
+
+## 3. Wireless Accessory Configuration (WAC)
+Specific to Apple iOS devices.
+
+- **Mechanism**: Uses Apple's MFi/WAC protocol to pass Wi-Fi settings from an iPhone/iPad directly to the device without manual password entry.
+- **Status**: Detected automatically by iOS when a new SoundTouch device is in setup mode.
+
+---
+
+## 4. USB Setup (Legacy)
+Primarily used for older SoundTouch Series I and II devices or as a last resort.
+
+- **Mechanism**: Physical connection via Micro-USB to a computer running the SoundTouch Setup application.
+- **Process**:
+  1. Connect USB cable.
+  2. The desktop app communicates via a proprietary HID or Serial-over-USB protocol.
+  3. The app pushes Wi-Fi credentials.
+  4. References to this exist in the firmware as `lost_USB_connection` and `connect_device` (see `setup_wizard.xml`).
+
+---
+
+## Technical Details: The "Gabbo" Protocol
+The Stockholm firmware contains references to a communication layer called **Gabbo**.
+- **File**: `setup/js/gabbo_setup_bco.js`
+- **Function**: Handles the state machine for Wi-Fi connection, account pairing, and error handling during setup.
+- **Relationship**: It appears to be an internal wrapper for the messages sent between the setup client (App or Browser) and the device firmware.
+
+## Redirection during Setup
+While the `soundtouch-service` focuses on migrating existing devices, a truly "clean" setup to a custom service would require:
+1. Intercepting the initial account pairing request.
+2. Providing a mock "Marge" service that accepts any credentials.
+3. Patching the `SoundTouchSdkPrivateCfg.xml` during or immediately after the Wi-Fi connection phase.
+
+---
+
+## Comparison: Initial Setup vs. Migration
+
+| Feature | Initial Setup | Migration (soundtouch-service) |
+| :--- | :--- | :--- |
+| **Connectivity** | BLE, AP Mode, USB, WAC | Ethernet/Wi-Fi (existing) |
+| **Credentials** | Required (SSID/Pass) | Not required (uses existing) |
+| **Access** | Web UI / App protocol | SSH (root) |
+| **Primary File** | `setup/index.html` | `SoundTouchSdkPrivateCfg.xml` |
+| **Use Case** | Out-of-the-box / Reset | Redirecting active devices |

+# HTTPS Setup & 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.
+
+## 1. Automated Migration (Hosts Method)
+
+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"
+```
+
+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
+
+The AfterTouch service automatically generates a Root CA when it first starts.
+
+- **CA Certificate**: `data/certs/ca.crt`
+- **CA Private Key**: `data/certs/ca.key`
+
+### 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`
+
+### 3. Built-in HTTPS Support
+
+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.
+
+- **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.
+
+#### TLS Security & Debugging
+
+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).
+
+- **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)
+
+#### 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:
+
+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.
+
+### 4. Reverse Proxy (Optional)
+
+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`.
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name streaming.bose.com bmx.bose.com stats.bose.com updates.bose.com;
+
+    ssl_certificate /path/to/generated-cert.crt;
+    ssl_certificate_key /path/to/generated-cert.key;
+
+    # Secure TLS configuration (matches soundtouch-service defaults)
+    ssl_protocols TLSv1.2;
+    ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-CHACHA20-POLY1305:AES128-GCM-SHA256:AES256-GCM-SHA384';
+
+    location / {
+        proxy_pass http://localhost:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+## 5. Manual CA Injection (Legacy/Manual)
+
+If you prefer to inject the CA certificate manually:
+
+1.  Copy `ca.crt` to the device:
+    ```bash
+    scp data/certs/ca.crt root@{deviceIP}:/tmp/
+    ```
+2.  Append it to the trust store on the device:
+    ```bash
+    ssh root@{deviceIP} "(rw || mount -o remount,rw /) && cat /tmp/ca.crt >> /etc/pki/tls/certs/ca-bundle.crt"
+    ```
+
+    ## 6. Verifying Connectivity
+
+    You can verify that your device can correctly reach the `soundtouch-service` over HTTPS using the management web UI.
+
+    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.

+
+## Implementation Details
+
+### 1. Configuration File Management
+
+#### IoT.xml Structure
+```xml
+<?xml version="1.0" encoding="UTF-8" ?>
+<Configuration 
+    clientID="{device-unique-uuid}" 
+    iotEndpoint="{aws-iot-endpoint}" 
+    deployment="{PROD|DEV|TEST}" />
+```
+
+#### Loading Configuration (C++ Implementation)
+```cpp
+#include <rapidxml/rapidxml.hpp>
+#include <fstream>
+
+struct IoTConfig {
+    std::string clientID;
+    std::string iotEndpoint;
+    std::string deployment;
+};
+
+IoTConfig loadIoTConfig(const std::string& configPath) {
+    std::ifstream file(configPath);
+    std::string content((std::istreambuf_iterator<char>(file)),
+                        std::istreambuf_iterator<char>());
+    
+    rapidxml::xml_document<> doc;
+    doc.parse<0>(&content[0]);
+    
+    auto configNode = doc.first_node("Configuration");
+    
+    IoTConfig config;
+    config.clientID = configNode->first_attribute("clientID")->value();
+    config.iotEndpoint = configNode->first_attribute("iotEndpoint")->value();
+    config.deployment = configNode->first_attribute("deployment")->value();
+    
+    return config;
+}
+```
+
+### 2. Certificate Management
+
+#### Certificate Files Structure
+```
+/mnt/nv/IoTCerts/
+├── iot-cert.pem.crt      # Device client certificate
+├── iot-private.pem.key   # Device private key
+└── default.pem           # Additional cert data
+
+/var/lib/iot/
+└── rootCA.crt           # AWS IoT Root CA
+```
+
+#### Certificate Registration Process
+```cpp
+#include <openssl/x509.h>
+#include <openssl/rsa.h>
+#include <openssl/pem.h>
+
+class IoTCertificateManager {
+private:

+        X509_REQ_set_subject_name(req, name);
+        
+        // Set public key
+        EVP_PKEY* pkey = EVP_PKEY_new();
+        EVP_PKEY_set1_EC_KEY(pkey, eckey);

+    }
+    
+    bool sendCSRToEndpoint(X509_REQ* req, EVP_PKEY* pkey) {
+        // Send CSR to voice.api.bose.io/alexa/certificate
+        // Receive certificate response
+        // Store certificate and private key
+        return true;
+    }
+};
+
+const std::string IoTCertificateManager::CERT_ENDPOINT = 
+    "https://voice.api.bose.io/alexa/certificate";
+const std::string IoTCertificateManager::CERT_PATH =

+const std::string IoTCertificateManager::KEY_PATH = 
+    "/mnt/nv/IoTCerts/iot-private.pem.key";
+```
+
+### 3. MQTT Connection Implementation
+
+#### AWS IoT SDK Integration
+```cpp
+#include <aws/iot/MqttClient.h>
+#include <aws/iot/ShadowClient.h>
+
+class IoTConnectionManager {

+```
+
+### 4. Device Shadow Operations
+
+#### Shadow Message Structures
+```cpp
+#include <rapidjson/document.h>
+#include <rapidjson/writer.h>
+#include <rapidjson/stringbuffer.h>

+
+#### Shadow Update Implementation
+```cpp

+
+### 5. Service Integration
+
+#### Shepherd Service Configuration
+```xml
+<!-- /opt/Bose/etc/Shepherd-noncore.xml -->
+<ShepherdConfig>
+  <daemon name="STSCertified"/>
+  <daemon name="IoT">
+    <env name="IOT_CONFIG_PATH">/mnt/nv/BoseApp-Persistence/1/IoT.xml</env>

+```
+
+#### System Startup Integration
+```bash
+#!/bin/bash
+# /etc/init.d/SoundTouch fragment
+
+# Create IoT directories
+mkdir -p /mnt/nv/BoseLog /mnt/nv/IoTCerts /mnt/nv/BoseApp-Persistence/1

+```
+
+## Error Handling and Debugging
+
+### Connection Retry Logic
+```cpp
+class ConnectionRetryManager {
+private:
+    int maxRetries = 10;
+    int retryDelaySeconds = 5;
+    
+public:
+    awsiotsdk::ResponseCode connectWithRetry(IoTConnectionManager& manager) {

+        std::cerr << "Failed to connect after " << maxRetries << " attempts" << std::endl;
+        return awsiotsdk::ResponseCode::FAILURE;
+    }
+};
+```
+
+### Logging and Monitoring
+```cpp
+class IoTLogger {
+public:
+    static void logConnectionStatus(const std::string& status) {
+        std::cout << "[IoT] Connection status: " << status << std::endl;
+    }
+    
+    static void logShadowResponse(awsiotsdk::ShadowResponseType response, 
+                                 const std::string& payload) {

+            std::cerr << "[IoT] Failed to generate iot certificate" << std::endl;
+        }
+    }
+};
+```
+
+## Testing and Validation
+
+### Unit Test Example
+```cpp
+#include <gtest/gtest.h>
+
+class IoTConfigTest : public ::testing::Test {
+protected:
+    void SetUp() override {
+        // Create test configuration file
+        std::ofstream file("/tmp/test_iot.xml");
+        file << R"(<?xml version="1.0" encoding="UTF-8" ?>
+<Configuration clientID="test-client-id" 
+               iotEndpoint="test.iot.amazonaws.com" 
+               deployment="TEST" />)";
+        file.close();
+    }
+};
+
+TEST_F(IoTConfigTest, LoadConfiguration) {
+    auto config = loadIoTConfig("/tmp/test_iot.xml");
+    
+    EXPECT_EQ(config.clientID, "test-client-id");
+    EXPECT_EQ(config.iotEndpoint, "test.iot.amazonaws.com");
+    EXPECT_EQ(config.deployment, "TEST");
+}
+
+TEST_F(IoTConfigTest, ShadowMessageBuilder) {
+    DeviceState state;
+    state.deviceState = "CONNECTED";
+    state.powerState = "ON";
+    
+    std::string json = ShadowMessageBuilder::createReportedState(state);
+    
+    // Verify JSON contains expected fields
+    EXPECT_TRUE(json.find("\"deviceState\":\"CONNECTED\"") != std::string::npos);
+    EXPECT_TRUE(json.find("\"powerState\":\"ON\"") != std::string::npos);
+}
+```
+
+## Security Best Practices
+
+1. **Certificate Management**
+   - Store private keys with 600 permissions
+   - Rotate certificates regularly
+   - Use hardware security modules when available
+
+2. **Network Security**
+   - Always use TLS 1.2 or higher
+   - Validate certificate chains
+   - Implement certificate pinning
+
+3. **Configuration Security**
+   - Encrypt sensitive configuration data
+   - Use secure storage for credentials
+   - Implement configuration validation
+
+## Troubleshooting Common Issues
+
+### Certificate Problems
+```bash
+# Check certificate validity
+openssl x509 -in /mnt/nv/IoTCerts/iot-cert.pem.crt -text -noout
+
+# Verify private key matches certificate
+openssl x509 -noout -modulus -in /mnt/nv/IoTCerts/iot-cert.pem.crt | openssl md5
+openssl rsa -noout -modulus -in /mnt/nv/IoTCerts/iot-private.pem.key | openssl md5
+```
+
+### Connection Issues
+```bash
+# Test MQTT connectivity
+mosquitto_pub -h a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com \
+              -p 8883 --cafile /var/lib/iot/rootCA.crt \
+              --cert /mnt/nv/IoTCerts/iot-cert.pem.crt \
+              --key /mnt/nv/IoTCerts/iot-private.pem.key \
+              -t '$aws/things/test/shadow/update' \
+              -m '{"state":{"reported":{"test":"value"}}}'
+```
+
+### Service Debugging
+```bash
+# Check service status
+ps aux | grep IoT
+
+# Monitor system logs
+tail -f /mnt/nv/BoseLog/IoT.log
+
+# Check Shepherd status
+shepherdd --status
+```
+
+## MQTT Monitoring and Research
+
+### Direct Device Credential Access
+
+With device certificates and private keys available from firmware backups, it's technically possible to monitor MQTT traffic:
+
+```bash
+# Subscribe to your device's shadow events only
+CLIENT_ID="577ecfcc-2db3-4989-92c9-76d7704f9fb3"  # Your device's UUID
+mosquitto_sub -h a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com \
+              -p 8883 --cafile /var/lib/iot/rootCA.crt \
+              --cert /mnt/nv/IoTCerts/iot-cert.pem.crt \
+              --key /mnt/nv/IoTCerts/iot-private.pem.key \
+              -t "\$aws/things/$CLIENT_ID/shadow/update/accepted"
+```
+
+### Security Constraints and Limitations
+
+#### AWS IoT Policy Restrictions
+Device certificates are bound to restrictive policies:
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": "iot:Connect",
+      "Resource": "arn:aws:iot:us-east-1:*:client/${iot:ClientId}"
+    },
+    {
+      "Effect": "Allow",
+      "Action": ["iot:Publish", "iot:Subscribe", "iot:Receive"],
+      "Resource": [
+        "arn:aws:iot:us-east-1:*:topic/$aws/things/${iot:ClientId}/shadow/*"
+      ]
+    }
+  ]
+}
+```
+
+**Limitations:**
+- Access only to your specific device topics
+- No wildcard subscriptions (`+` or `#`)
+- No cross-device monitoring
+- Potential IP geolocation restrictions
+- Certificate revocation for unusual activity
+
+### Alternative Monitoring Approaches
+
+#### Network Traffic Capture (Recommended)
+```bash
+# Capture MQTT traffic patterns without authentication
+tcpdump -i eth0 -s0 -w soundtouch_iot.pcap host a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com
+
+# Monitor connection patterns in real-time
+tcpdump -i eth0 -n -A "host a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com and port 8883"
+
+# Extract timing and packet size information
+tcpdump -i eth0 -ttt -s0 "host a2bhvr9c4wn4ya.iot.us-east-1.amazonaws.com"
+```
+
+#### Local MQTT Broker for Testing
+```bash
+# Set up local Mosquitto broker
+sudo apt-get install mosquitto mosquitto-clients
+
+# Configure TLS (optional)
+cat > /etc/mosquitto/conf.d/tls.conf << EOF
+port 8883
+cafile /path/to/ca.crt
+certfile /path/to/server.crt
+keyfile /path/to/server.key
+require_certificate true
+use_identity_as_username true
+EOF
+
+# Test local shadow operations
+mosquitto_pub -h localhost -p 8883 \
+              -t '$aws/things/test-device/shadow/update' \
+              -m '{"state":{"reported":{"deviceState":"CONNECTED"}}}'
+```
+
+### Message Analysis and Documentation
+
+Expected shadow message patterns:
+
+```cpp
+// Power state transitions
+{
+  "state": {
+    "reported": {
+      "deviceState": "CONNECTED",
+      "powerState": "ON|OFF"
+    }
+  },
+  "timestamp": 1703875200
+}
+
+// Audio control updates  
+{
+  "state": {
+    "reported": {
+      "volume": 25,
+      "muted": false,
+      "source": "SPOTIFY"
+    }
+  }
+}
+
+// Multi-room coordination
+{
+  "state": {
+    "reported": {
+      "zoneState": "master|slave",
+      "groupMembers": ["device1", "device2"],
+      "groupName": "Living Room"
+    }
+  }
+}
+```
+
+### Legal and Ethical Guidelines
+
+**Important Warnings:**
+- Only monitor devices you personally own
+- Using device credentials outside the device may violate Bose Terms of Service
+- Accessing Bose's AWS infrastructure could be considered unauthorized
+- Certificate abuse may result in device blacklisting
+- Service shutdown in May 2026 makes this a temporary research opportunity
+
+**Recommended Usage:**
+- Document message formats for local alternative development
+- Understand state transition patterns
+- Test compatibility with local MQTT brokers
+- Prepare migration strategies before cloud shutdown
+
+### Research Implementation Example
+
+```cpp
+class IoTResearchMonitor {
+private:
+    std::string deviceClientId;
+    std::ofstream messageLog;
+    
+public:
+    void captureMessagePatterns() {
+        // Subscribe only to owned device topics
+        std::string topic = "$aws/things/" + deviceClientId + "/shadow/update/accepted";
+        
+        auto messageHandler = [this](const std::string& topic, const std::string& payload) {
+            // Log message structure for analysis

+            messageLog << "---" << std::endl;
+            
+            // Parse and document state transitions
+            documentStateTransition(payload);
+        };
+        
+        // WARNING: Only use with your own device certificates
+        connectToAWSIoT(messageHandler);
+    }
+    
+    void documentStateTransition(const std::string& json) {
+        // Analyze JSON structure for local implementation
+        rapidjson::Document doc;
+        doc.Parse(json.c_str());
+        
+        if (doc.HasMember("state") && doc["state"].HasMember("reported")) {
+            // Document field types and value ranges
+            auto& reported = doc["state"]["reported"];
+            
+            for (auto& field : reported.GetObject()) {
+                std::cout << "Field: " << field.name.GetString() 
+                         << ", Type: " << getJSONType(field.value) << std::endl;
+            }
+        }
+    }
+};
+```
+
+This implementation guide provides the foundation for integrating with the Bose SoundTouch IoT system using AWS IoT Core, certificate-based authentication, and device shadow operations. The monitoring capabilities should be used responsibly and only for research purposes to develop local alternatives.

+# MAC Address to Serial Number Mapping
+
+**Understanding and troubleshooting device identification in SoundTouch service**
+
+This guide explains how the SoundTouch service handles device identification through MAC address to serial number mapping, and how to troubleshoot related issues.
+
+## 📋 **Overview**
+
+The SoundTouch service uses two different identifiers for devices:
+
+- **MAC Address** (`A81B6A536A98`) - Used in HTTP API requests and UPnP discovery
+- **Serial Number** (`I6332527703739342000020`) - Used for internal file storage
+
+The service automatically maps between these identifiers so that API requests using MAC addresses can access files stored using serial numbers.
+
+## 🔍 **How It Works**
+
+### Request Flow
+```
+1. HTTP Request: GET /streaming/account/3230304/device/A81B6A536A98/presets
+2. MAC Resolution: A81B6A536A98 → I6332527703739342000020
+3. File Access: accounts/3230304/devices/I6332527703739342000020/Presets.xml
+```
+
+### UPnP Discovery Integration
+The service extracts MAC addresses from UPnP device descriptions:
+
+```xml
+<!-- From http://192.168.1.100:8091/XD/BO5EBO5E-F00D-F00D-FEED-A81B6A536A98.xml -->
+<root xmlns="urn:schemas-upnp-org:device-1-0">
+    <device>
+        <friendlyName>Sound Machinery</friendlyName>
+        <modelName>SoundTouch 10</modelName>
+        <serialNumber>A81B6A536A98</serialNumber>  <!-- MAC address here -->
+    </device>
+</root>
+```
+
+## ⚙️ **Automatic Setup**
+
+The mapping is created automatically when the service starts:
+
+1. **Directory Scan**: Service scans `data/accounts/{account}/devices/{serial}/`
+2. **DeviceInfo.xml**: Reads MAC address from each device's info file
+3. **Mapping Creation**: Creates MAC → Serial mapping in memory
+4. **Normalization**: Handles different MAC address formats automatically
+
+## 🛠️ **Supported MAC Address Formats**
+
+The service handles all common MAC address formats automatically:
+
+| Format      | Example             | Status      |
+|-------------|---------------------|-------------|
+| Standard    | `A81B6A536A98`      | ✅ Supported |
+| Lowercase   | `a81b6a536a98`      | ✅ Supported |
+| With Colons | `A8:1B:6A:53:6A:98` | ✅ Supported |
+| With Dashes | `A8-1B-6A-53-6A-98` | ✅ Supported |
+| Mixed Case  | `a81B6a536A98`      | ✅ Supported |
+| With Spaces | ` A81B6A536A98 `    | ✅ Supported |
+
+## 🔧 **Troubleshooting**
+
+### Problem: API requests fail with "file not found" errors
+
+**Symptoms:**
+```
+GET /streaming/account/3230304/device/A81B6A536A98/presets
+→ 500 Internal Server Error
+→ Log: "open .../devices/A81B6A536A98/Presets.xml: no such file or directory"
+```
+
+**Diagnosis:**
+1. Check if mapping exists:
+   ```bash
+   # Look for device directory
+   ls data/accounts/3230304/devices/
+   # Should show serial numbers like: I6332527703739342000020
+   ```
+
+2. Check DeviceInfo.xml:
+   ```bash
+   cat data/accounts/3230304/devices/I6332527703739342000020/DeviceInfo.xml
+   # Look for <macAddress> field
+   ```
+
+**Solutions:**
+
+#### Solution 1: Restart the Service
+The mapping is created at startup. Simply restart:
+```bash
+sudo systemctl restart soundtouch-service
+```
+
+#### Solution 2: Check DeviceInfo.xml Format
+Ensure the MAC address is present:
+```xml
+<info deviceID="I6332527703739342000020">
+    <networkInfo type="SCM">
+        <macAddress>A81B6A536A98</macAddress>  <!-- Must be present -->
+        <ipAddress>192.168.178.35</ipAddress>
+    </networkInfo>
+</info>
+```
+
+#### Solution 3: Manual Device Addition
+If the device was added manually, ensure proper structure:
+```bash
+# Create device directory using serial number
+mkdir -p data/accounts/3230304/devices/I6332527703739342000020
+
+# Create DeviceInfo.xml with MAC address
+cat > data/accounts/3230304/devices/I6332527703739342000020/DeviceInfo.xml << EOF
+<?xml version="1.0" encoding="UTF-8"?>
+<info deviceID="I6332527703739342000020">
+    <name>My SoundTouch Device</name>
+    <networkInfo type="SCM">
+        <macAddress>A81B6A536A98</macAddress>
+        <ipAddress>192.168.1.100</ipAddress>
+    </networkInfo>
+</info>
+EOF
+```
+
+### Problem: UPnP discovery not creating mappings
+
+**Check UPnP accessibility:**
+```bash
+# Test UPnP endpoint directly
+curl http://192.168.1.100:8091/XD/BO5EBO5E-F00D-F00D-FEED-A81B6A536A98.xml
+
+# Should return XML with <serialNumber> field
+```
+
+**Enable debug logging:**
+```bash
+# Check service logs for UPnP activity
+journalctl -u soundtouch-service -f | grep UPnP
+```
+
+### Problem: Case or format mismatches
+
+This should be handled automatically, but you can verify:
+
+**Test different formats:**
+```bash
+# All of these should work the same:
+curl http://localhost:8000/streaming/account/3230304/device/A81B6A536A98/presets
+curl http://localhost:8000/streaming/account/3230304/device/a81b6a536a98/presets
+curl http://localhost:8000/streaming/account/3230304/device/A8:1B:6A:53:6A:98/presets
+```
+
+## 📊 **Monitoring and Diagnostics**
+
+### Check Current Mappings
+The service logs mapping creation at startup:
+```bash
+journalctl -u soundtouch-service | grep "MAC.*serial"
+```
+
+### Verify File Structure
+Ensure proper directory organization:
+```
+data/
+└── accounts/
+    └── 3230304/
+        └── devices/
+            └── I6332527703739342000020/     # Serial number directory
+                ├── DeviceInfo.xml           # Contains MAC address
+                ├── Presets.xml
+                └── Sources.xml
+```

+
+## 🏗️ **Technical Implementation**
+
+For developers interested in the technical details:
+
+### Normalization Algorithm
+```go
+// MAC addresses are normalized by:
+// 1. Removing spaces, colons, and dashes
+// 2. Converting to uppercase
+// Examples:
+// "a8:1b:6a:53:6a:98" → "A81B6A536A98"
+// "A8-1B-6A-53-6A-98" → "A81B6A536A98"
+```
+
+### Lookup Process
+```go
+// 1. Try exact match first
+// 2. If not found, try normalized version
+// 3. Return serial number for file access
+```
+
+### Performance
+- **Lookup Time**: O(1) - Hash map lookup
+- **Memory Usage**: ~40 bytes per device mapping
+- **Initialization**: Scans all devices once at startup
+
+## 📝 **Best Practices**
+
+1. **Use Discovery**: Let UPnP discovery create mappings automatically
+2. **Consistent Format**: Store MAC addresses consistently in DeviceInfo.xml
+3. **Service Restart**: Restart service after manual device additions
+4. **Monitoring**: Check logs for mapping creation during startup
+5. **Backup**: Keep DeviceInfo.xml files backed up
+
+## ⚠️ **Known Limitations**
+
+- Mappings are created only at service startup
+- Manual device additions require service restart
+- MAC addresses must be present in DeviceInfo.xml
+- No automatic cleanup of stale mappings (restart required)

+# THIS IS A PLANNED TO BE THE MIGRATION GUIDE
+
+> This migration guide is not finalized, yet.
+> We're using it as an orientation for the required implementation.
+
+---
+
+# Complete Migration Guide - From Bose Cloud to Local SoundTouch Service
+
+## Overview
+
+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.
+
+## What You'll Need
+
+### 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:
+
+```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
+```
+
+#### 1.3 Verify Installation
+
+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**
+
+![SoundTouch Service Dashboard](../images/dashboard-home.png)
+*Example: SoundTouch Service main dashboard*
+
+### Option B: Docker Installation
+
+If you prefer Docker, run:
+
+```bash
+docker run -d \
+  --name soundtouch-service \
+  --restart unless-stopped \
+  -p 8000:8000 \
+  -p 8443:8443 \
+  -v soundtouch-data:/data \
+  gesellix/soundtouch-service:latest
+```
+
+## Step 2: Create Your Account
+
+### 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.
+
+#### Example Migration Output:
+```text

+
+## Step 7: Complete Account Migration
+
+### 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)

+### Professional Migration & Safety Guide
+
+Starting a migration on real hardware requires a "Safety First" approach. This guide outlines the safety features implemented in the `soundtouch-service` and provides a checklist for a successful migration.
+
+#### 🛠 Technical Safety Enhancements
+
+The following features are built into the `soundtouch-service` to ensure stability and easy rollbacks:
+
+1.  **Off-Device Backups**: Before any migration starts, the service automatically fetches the original `SoundTouchSdkPrivateCfg.xml` and `/etc/hosts` from your speaker and saves them locally in your `data/default/devices/<SERIAL>/` directory. This ensures you have a recovery path even if the speaker's filesystem becomes inaccessible.
+2.  **Pre-flight Write Verification**: The migration process includes a mandatory check for SSH write access (`rw`) before attempting any modifications. This prevents "half-baked" migrations where a script might fail halfway through due to a read-only filesystem.
+3.  **Automatic Safety on Sync**: Running a "Sync" in the Web UI or CLI automatically triggers an off-device backup, making it the perfect first step for any new device discovery.
+
+#### 📋 Professional Migration Checklist
+
+Before you proceed with the actual migration, follow these steps:
+
+1.  **Enable SSH Access (Prerequisite)**: This toolkit requires SSH access to your speakers, which is not enabled by default. 
+    - Create an empty file named `remote_services` on a USB stick.
+    - Insert the USB stick into the SoundTouch speaker's **SERVICE** port.
+    - Reboot the speaker (unplug and replug).
+    - The speaker will now allow SSH connections as `root` with no password.
+    - **Verify**: Run `ssh -oHostKeyAlgorithms=+ssh-rsa root@<SPEAKER-IP>` to confirm access. (Note: older devices may require enabling `ssh-rsa` support).
+2.  **Network Isolation (Optional but Recommended)**: Ensure the device is on a stable wired connection if possible, or a dedicated 2.4GHz SSID to avoid drops during SSH operations.
+3.  **Initial Discovery & Sync**: 
+    - Run `soundtouch-cli discover devices` to ensure connectivity.
+    - Use the Web UI or CLI to "Sync" the device. This will automatically backup your presets and system configuration files to your local server.
+4.  **Validate SSH Access**: Confirm the device responds to SSH without a password. 
+    - In the Web UI **Migration** tab, select your speaker and verify that the "SSH Connection" status shows ✅ Success.
+    - This toolkit automatically handles the necessary SSH parameters (ciphers and key exchanges) required by older Bose firmware.
+5.  **Migration Methods**: 
+    - **XML Migration (Default)**: Less invasive, only changes the application config. Best for simple redirection.
+    - **Hosts Migration**: Modifies `/etc/hosts` on the device. Good for system-wide redirection of specific domains.
+    - **ResolvConf Migration**: Points the device to the AfterTouch DNS server. Best for discovering unknown Bose endpoints and dynamic interception. **Note**: This method requires the DNS Discovery Server to be running on port 53. The service includes a pre-flight check to ensure the server is properly bound before allowing this migration.
+6.  **Monitor Logs**: Run the `soundtouch-service` with `DEBUG` or `INFO` logging to see the step-by-step progress of the migration.
+
+#### 🔄 Rollback Strategy
+
+If something goes wrong or you want to return to the original Bose cloud services:
+
+*   **Standard Revert**: Use the "Revert Migration" button in the Web UI or the corresponding CLI command. This restores the `.original` files created on the device.
+*   **Emergency Recovery**: If the device is unreachable via the UI but SSH still works, you can manually restore the files from your local `data/` directory using `scp` or the backups created on-device (`.original`).
+*   **Factory Reset**: As a last resort, Bose SoundTouch devices can be factory reset (usually by holding '1' and 'Volume Down' while plugging in). This will wipe all settings and return the device to the stock firmware configuration (the firmware itself remains at the current version, but configurations are reset).
+
+By using the built-in off-device backups and pre-flight checks, the risk of "bricking" or losing configuration during the transition is significantly reduced.

+# MQTT Integration Design for SoundTouch Service
+
+## Overview
+
+This document outlines the design for integrating MQTT support into the existing SoundTouch service to simulate AWS IoT Core functionality. The integration will provide real-time device communication, shadow state management, and prepare for the AWS IoT service shutdown in May 2026.
+

+func (s *Server) StartMQTT() error {
+    if !s.mqttEnabled {
+        return nil
+    }
+    
+    go func() {
+        if err := s.mqttBroker.Start(); err != nil {
+            log.Printf("MQTT broker error: %v", err)
+        }
+    }()
+    
+    return nil
+}
+```
+
+#### B. Configuration Integration (`cmd/soundtouch-service/main.go`)
+```go
+// Add to serviceConfig struct
+type serviceConfig struct {
+    // ... existing fields ...
+    
+    // New MQTT configuration fields
+    mqttEnabled         bool     `mapstructure:"mqtt_enabled"`
+    mqttPort           int      `mapstructure:"mqtt_port"`

+    mqttShadowPersist  bool     `mapstructure:"mqtt_shadow_persist"`
+}
+
+// Update main function to initialize MQTT
+func main() {
+    // ... existing initialization ...
+    
+    // Initialize MQTT if enabled
+    if cfg.mqttEnabled {
+        mqttConfig := &mqtt.Config{
+            Enabled:         cfg.mqttEnabled,
+            Port:           cfg.mqttPort,

+            KeyFile:        cfg.mqttTLSKey,
+            DeviceCertPath: cfg.mqttDeviceCertPath,
+            ShadowPersist:  cfg.mqttShadowPersist,
+        }
+        
+        if err := server.InitMQTTBroker(mqttConfig); err != nil {
+            log.Fatalf("Failed to initialize MQTT broker: %v", err)
+        }
+        
+        if err := server.StartMQTT(); err != nil {
+            log.Fatalf("Failed to start MQTT broker: %v", err)
+        }
+        
+        log.Printf("MQTT broker started on port %d", cfg.mqttPort)
+    }
+    
+    // ... rest of existing main function ...
+}
+```
+
+### 4. Enhanced Device Discovery
+
+#### A. MQTT Device Discovery (`pkg/service/mqtt/discovery.go`)
+```go
+package mqtt
+
+import (
+    "log"
+    "time"
+    
+    "github.com/gesellix/bose-soundtouch/pkg/models"
+    "github.com/mochi-co/mqtt/v2/packets"
+)
+
+type DeviceDiscoveryHook struct {
+    deviceRegistry map[string]*models.Device
+    onDeviceFound  func(*models.Device)
+}
+
+func NewDeviceDiscoveryHook() *DeviceDiscoveryHook {
+    return &DeviceDiscoveryHook{
+        deviceRegistry: make(map[string]*models.Device),
+    }
+}
+
+func (h *DeviceDiscoveryHook) ID() string {
+    return "device-discovery"
+}
+
+func (h *DeviceDiscoveryHook) OnConnect(cl *packets.Client, pk packets.Packet) error {
+    clientID := pk.Connect.ClientIdentifier
+    
+    log.Printf("MQTT device connected: %s", clientID)
+    
+    // Create device entry
+    device := &models.Device{
+        ID:           clientID,
+        ClientID:     clientID,
+        Name:         "MQTT Device",
+        LastSeen:     time.Now(),
+        MQTTOnline:   true,
+        Source:       "mqtt",
+    }
+    
+    h.deviceRegistry[clientID] = device
+    
+    if h.onDeviceFound != nil {
+        h.onDeviceFound(device)
+    }
+    
+    return nil
+}
+
+func (h *DeviceDiscoveryHook) OnDisconnect(cl *packets.Client, err error) {
+    clientID := cl.ID
+    
+    log.Printf("MQTT device disconnected: %s", clientID)
+    
+    if device, exists := h.deviceRegistry[clientID]; exists {
+        device.MQTTOnline = false
+        device.LastSeen = time.Now()
+    }
+}
+```
+
+#### B. Integration with Existing Discovery (`pkg/discovery/mqtt.go`)
+```go
+package discovery
+
+import (
+    "context"
+    "time"
+    
+    "github.com/gesellix/bose-soundtouch/pkg/models"
+)
+
+type MQTTDiscovery struct {
+    deviceRegistry map[string]*models.Device
+    enabled        bool
+}
+
+func NewMQTTDiscovery() *MQTTDiscovery {
+    return &MQTTDiscovery{
+        deviceRegistry: make(map[string]*models.Device),
+        enabled:        true,
+    }
+}
+
+func (d *MQTTDiscovery) DiscoverDevices(ctx context.Context, timeout time.Duration) ([]*models.Device, error) {
+    if !d.enabled {
+        return []*models.Device{}, nil
+    }
+    
+    var devices []*models.Device
+    for _, device := range d.deviceRegistry {
+        if device.MQTTOnline {
+            devices = append(devices, device)
+        }
+    }
+    
+    return devices, nil
+}
+
+func (d *MQTTDiscovery) AddDevice(device *models.Device) {
+    d.deviceRegistry[device.ClientID] = device
+}
+
+func (d *MQTTDiscovery) RemoveDevice(clientID string) {
+    delete(d.deviceRegistry, clientID)
+}
+```
+
+### 5. Configuration File Extensions
+
+#### A. Default Configuration (`config.yaml`)
+```yaml
+# Existing configuration...
+
+# MQTT Configuration
+mqtt:
+  enabled: false
+  port: 8883
+  tls:
+    cert_file: "/etc/ssl/certs/soundtouch-mqtt.crt"
+    key_file: "/etc/ssl/private/soundtouch-mqtt.key"
+  
+  # Device certificate validation
+  device_certs:
+    path: "/etc/soundtouch/device-certs"
+    auto_load: true
+    
+  # Shadow state management
+  shadow:
+    persist: true
+    ttl: 86400  # 24 hours
+    
+  # Bridge configuration
+  bridge:
+    enabled: true
+    sync_interval: 30s
+```
+
+#### B. Environment Variable Support
+```bash
+# MQTT configuration via environment variables
+SOUNDTOUCH_MQTT_ENABLED=true
+SOUNDTOUCH_MQTT_PORT=8883
+SOUNDTOUCH_MQTT_TLS_CERT=/path/to/cert.pem
+SOUNDTOUCH_MQTT_TLS_KEY=/path/to/key.pem
+SOUNDTOUCH_MQTT_DEVICE_CERT_PATH=/path/to/device/certs
+SOUNDTOUCH_MQTT_SHADOW_PERSIST=true
+```
+
+### 6. API Extensions
+
+#### A. MQTT Status Endpoints
+```go
+// Add to handlers
+func (s *Server) handleMQTTStatus(c *gin.Context) {
+    if !s.mqttEnabled {
+        c.JSON(http.StatusNotImplemented, gin.H{
+            "error": "MQTT not enabled",
+        })
+        return
+    }
+    
+    status := gin.H{
+        "enabled":     s.mqttEnabled,
+        "port":        s.mqttConfig.Port,
+        "connected_devices": len(s.deviceClientIDs),
+        "shadow_count": s.mqttBroker.ShadowStore().Count(),
+    }
+    
+    c.JSON(http.StatusOK, status)
+}
+
+// Device shadow endpoint
+func (s *Server) handleDeviceShadow(c *gin.Context) {
+    deviceID := c.Param("deviceId")
+    clientID, exists := s.deviceClientIDs[deviceID]
+    if !exists {
+        c.JSON(http.StatusNotFound, gin.H{
+            "error": "Device not connected via MQTT",
+        })
+        return
+    }
+    
+    shadow := s.mqttBroker.ShadowStore().GetShadow(clientID)
+    if shadow == nil {
+        c.JSON(http.StatusNotFound, gin.H{
+            "error": "Shadow not found",
+        })
+        return
+    }
+    
+    c.JSON(http.StatusOK, shadow)
+}
+```
+
+### 7. Testing Strategy
+
+#### A. Unit Tests
+```go
+// pkg/service/mqtt/shadow_test.go
+func TestShadowStore_UpdateShadow(t *testing.T) {
+    store := NewShadowStore()
+    
+    payload := []byte(`{
+        "state": {
+            "reported": {
+                "powerState": "ON",
+                "volume": 25
+            }
+        }
+    }`)
+    
+    shadow, err := store.UpdateShadow("test-client", payload)
+    assert.NoError(t, err)
+    assert.Equal(t, "ON", shadow.State.Reported["powerState"])
+    assert.Equal(t, 25.0, shadow.State.Reported["volume"])
+    assert.Equal(t, 1, shadow.Version)
+}
+```
+
+#### B. Integration Tests
+```go
+// pkg/service/mqtt/integration_test.go
+func TestMQTTBrokerIntegration(t *testing.T) {
+    // Start test broker
+    broker := setupTestBroker(t)
+    go broker.Start()
+    defer broker.Stop()
+    
+    // Connect test client
+    client := mqtt.NewClient(mqtt.NewClientOptions().
+        AddBroker("tls://localhost:8883").
+        SetClientID("test-device"))
+    
+    // Test shadow operations
+    testShadowUpdate(t, client)
+    testShadowGet(t, client)
+}
+```
+
+### 8. Migration Path
+
+#### A. Gradual Rollout
+1. **Phase 1**: Deploy MQTT broker alongside existing HTTP service (disabled by default)
+2. **Phase 2**: Enable MQTT for testing with specific devices
+3. **Phase 3**: Enable bidirectional HTTP ↔ MQTT bridging
+4. **Phase 4**: Full MQTT support for all discovered devices
+5. **Phase 5**: Prepare for AWS IoT shutdown (May 2026)
+
+#### B. Backward Compatibility
+- All existing HTTP API endpoints continue to work
+- MQTT is purely additive functionality
+- Devices can be discovered via HTTP even with MQTT enabled
+- Configuration remains optional
+
+### 9. Monitoring and Logging
+
+#### A. MQTT Metrics
+```go
+type MQTTMetrics struct {
+    ConnectedDevices   int64
+    MessagesReceived   int64
+    MessagesSent       int64
+    ShadowUpdates      int64
+    AuthenticationFails int64
+    Uptime             time.Duration
+}
+
+func (b *Broker) GetMetrics() *MQTTMetrics {
+    return &MQTTMetrics{
+        ConnectedDevices:   int64(len(b.server.Clients)),
+        MessagesReceived:   b.server.Stats.MessagesReceived,
+        MessagesSent:       b.server.Stats.MessagesSent,
+        ShadowUpdates:      b.shadowStore.UpdateCount(),
+        AuthenticationFails: b.authHook.FailCount(),
+        Uptime:            time.Since(b.startTime),
+    }
+}
+```
+
+#### B. Logging Integration
+```go
+import "github.com/sirupsen/logrus"
+
+func (b *Broker) setupLogging() {
+    log := logrus.WithFields(logrus.Fields{
+        "component": "mqtt-broker",
+        "port":      b.config.Port,
+    })
+    
+    b.server.AddHook(&LoggingHook{logger: log}, nil)
+}
+```
+
+### 10. Security Considerations
+
+#### A. Certificate Validation
+- Validate device certificates against known device list
+- Implement certificate revocation checking
+- Support certificate rotation
+
+#### B. Access Control
+- Restrict topic access per device certificate
+- Implement rate limiting per client
+- Monitor for unusual connection patterns
+
+#### C. Data Protection
+- Encrypt shadow data at rest
+- Implement secure certificate storage
+- Audit logging for security events
+

+# Raspberry Pi Installation Guide
+
+This guide explains how to install the `soundtouch-service` as a persistent systemd service on a Raspberry Pi (tested on Raspberry Pi Zero 2W, 3, and 4).
+
+## Automated Installer
+
+We provide a specialized installer script located in the `scripts/raspberry-pi/` directory of the repository.
+
+### Features
+*   **Automatic start on boot**: Installs a systemd unit.
+*   **Non-root operation**: Uses `AmbientCapabilities` to bind to ports 80/443 without root privileges.
+*   **Arch Detection**: Automatically selects the correct binary for `armv7`, `arm64`, or `amd64`.
+*   **Easy Updates**: Re-running the script updates the binary to the latest version.
+
+### Installation Steps
+
+1.  **Download the installer**:
+    ```bash
+    curl -fsSL -o install.sh https://raw.githubusercontent.com/gesellix/bose-soundtouch/main/scripts/raspberry-pi/install.sh
+    ```
+
+2.  **Run with sudo**:
+    ```bash
+    sudo bash install.sh
+    ```
+
+### Overriding Defaults
+
+You can customize the installation using environment variables:
+
+```bash
+sudo \
+  VERSION=v0.17.0 \
+  HOSTNAME_FQDN=soundtouch.local \
+  HTTP_PORT=80 \
+  HTTPS_PORT=443 \
+  bash install.sh
+```
+
+### Updating the Service
+
+To update the service to a specific version, run the installer with the version as an argument:
+
+```bash
+sudo bash install.sh v0.18.1
+```
+
+The installer will automatically fetch the latest version of itself for that release and then update the service binary and restart it.
+
+## Management
+
+Once installed, use standard `systemctl` commands to manage the service:
+
+```bash
+# Check status
+systemctl status soundtouch-service
+
+# Follow logs
+journalctl -u soundtouch-service -f
+
+# Restart
+sudo systemctl restart soundtouch-service
+```
+
+## Configuration
+
+Configuration is stored in `/etc/soundtouch-service/soundtouch-service.env`. Note that settings saved via the Web UI (in `settings.json`) will take precedence over these environment variables once the service is running.
+
+For more details, see the [scripts/raspberry-pi/README.md](../../scripts/raspberry-pi/README.md) in the repository.

+
+## Installation
+
+### Install from Source
+```bash
+go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-service@latest
+```
+
+### Build from Repository
+```bash
+git clone https://github.com/gesellix/bose-soundtouch.git
+cd Bose-SoundTouch
+go build -o soundtouch-service ./cmd/soundtouch-service
+```
+
+### Docker Support
+
+You can run the SoundTouch service using Docker or Docker Compose. 
+
+> **Note for macOS and Windows users**: The `--net host` option is only supported on Linux. On macOS and Windows, service discovery (mDNS, UPnP) will not work automatically within the container. You will need to manually enter your device's IP address in the management UI, and the service will communicate with it directly.
+
+#### Using Docker
+
+**Linux (with host networking for discovery):**
+```bash
+docker run -d \
+  --name soundtouch-service \
+  --network host \
+  -v $(pwd)/data:/app/data \
+  ghcr.io/gesellix/bose-soundtouch:latest
+```
+
+**macOS / Windows (with port mapping):**
+```bash
+docker run --rm -it \
+  -p 8000:8000 -p 8443:8443 \
+  -v $(pwd)/data:/app/data \
+  --env SERVER_URL=http://soundtouch.local:8000 \
+  --env HTTPS_SERVER_URL=https://soundtouch.local:8443 \
+  ghcr.io/gesellix/bose-soundtouch:latest
+```
+
+> **Note**: The hostnames configured via `SERVER_URL` and `HTTPS_SERVER_URL` are automatically added as Subject Alternative Names (SAN) to the generated TLS certificate, ensuring valid SSL connections.
+
+#### Using Docker Compose
+
+Create a `docker-compose.yml` file:
+
+```yaml
+services:
+  soundtouch-service:
+    image: ghcr.io/gesellix/bose-soundtouch:latest
+    container_name: soundtouch-service
+    # Linux users: use host networking for device discovery
+    # network_mode: host
+    # macOS/Windows users: use port mapping (discovery will be manual)
+    ports:
+      - "8000:8000"
+      - "8443:8443"
+    environment:
+      - PORT=8000
+      - SERVER_URL=http://soundtouch.local:8000
+      - HTTPS_SERVER_URL=https://soundtouch.local:8443
+      - DATA_DIR=/app/data
+    volumes:
+      - soundtouch-data:/app/data
+    restart: unless-stopped
+
+volumes:
+  soundtouch-data:
+```
+
+And run:
+
+```bash
+docker-compose up -d
+```
+
+## Quick Start
+
+### 1. Start the Service
+
+```bash
+# Start with default settings (port 8000)
+soundtouch-service
+```
+
+### 2. Access the Web Interface
+
+Open your browser to `http://localhost:8000` to access the management interface.
+
+### 3. Discover Devices
+
+The service will automatically start discovering SoundTouch devices on your network. You can also trigger manual discovery from the web UI or API.
+
+### 4. Migrate Devices
+
+Use the web interface or API to migrate devices from Bose cloud services to your local instance.
+
+## Configuration
+
+### Configuration Precedence
+
+The service supports multiple ways to configure its behavior. When multiple sources provide the same setting, the following precedence rules apply (highest to lowest):
+
+1.  **`settings.json`**: Settings saved via the Web UI (stored in the data directory) take the highest precedence. This ensures that changes made in the browser persist across service restarts even if environment variables or flags change.
+2.  **Environment Variables / CLI Flags**: If a setting is not present in `settings.json`, environment variables and flags are used.
+3.  **Default Values**: If no configuration is provided, the service uses its built-in defaults.
+
+> **Tip**: If you find that changes to environment variables are not taking effect, check the **Settings** tab in the Web UI or inspect the `settings.json` file in your data directory, as it might be overriding your manual configuration.
+
+### Configuration Options
+
+| Variable                           | Flag                       | Description                                                                                             | Default                   |

+### Configuration Examples
+
+```bash
+# Custom port and data directory
+PORT=9000 DATA_DIR=/home/user/soundtouch soundtouch-service
+
+# External server with custom URL
+SERVER_URL=https://my-soundtouch.example.com soundtouch-service --port 443
+
+# Development mode with full logging

+```
+
+## Device Migration
+
+### Understanding Migration
+
+Device migration switches your SoundTouch devices from Bose's cloud services to your local service instance. This process:
+
+1. **Backs up** existing device configuration
+2. **Updates** device service URLs to point to your local server
+3. **Maintains** all existing presets and settings
+4. **Enables** offline operation and advanced debugging
+
+### Migration Methods
+
+#### Web Interface (Recommended)
+
+1. Start the service: `soundtouch-service`
+2. Open `http://localhost:8000`
+3. Wait for device discovery to complete
+4. Click "Migrate" next to each device
+5. Monitor migration status in real-time
+
+#### API Migration
+
+```bash
+# Get migration summary first
+curl http://localhost:8000/setup/devices/192.168.1.100/summary
+
+# Perform migration
+curl -X POST http://localhost:8000/setup/devices/192.168.1.100/migrate
+
+# Verify migration status
+curl http://localhost:8000/devices
+```
+
+#### Advanced Migration Options
+
+```bash
+# Migration with proxy fallback for original services
+curl -X POST "http://localhost:8000/setup/devices/192.168.1.100/migrate?proxy_url=http://localhost:8000&marge=original&stats=original"
+
+# Migration with custom target URL
+curl -X POST "http://localhost:8000/setup/devices/192.168.1.100/migrate?target_url=https://my-server.com:8000"
+```
+
+### Post-Migration Verification
+
+After migration, verify the device is working correctly:
+
+```bash
+# Check device status
+curl http://localhost:8000/devices
+
+# Test preset functionality
+curl "http://192.168.1.100:8090/presets"
+
+# Monitor device events (if needed)
+curl "http://localhost:8000/devices/08DF1F0BA325/events"
+```
+
+#### ResolvConf Migration (DHCP-Aware DNS Redirection)
+
+The most robust and flexible DNS-based migration method. It utilizes the device's persistent `/mnt/nv/rc.local` script to inject a priority DNS hook into the system's DHCP configuration.
+
+> **Note**: This method requires the DNS Discovery Server to be bound to **port 53** on your local IP and **actually running**. Most devices do not support custom DNS ports in `/etc/resolv.conf`. If you use a custom port for testing, remember to switch back to `:53` and ensure the server has successfully bound to it (check Settings for status) before the actual migration.
+
+**Advantages:**
+- **Discovery**: Automatically discover all Bose endpoints queried by the device.
+- **Dynamic Interception**: Intercept new or unknown services without further device modifications.
+- **Fail-Safe**: Falls back to the standard network DNS (provided by your router) if the Aftertouch service is unavailable.
+- **DHCP Compatible**: Preserves your router's assigned search domain and secondary DNS servers.
+- **Wildcard Support**: Seamlessly handles `*.bose.com` redirection via your local DNS server.
+- **Persistent**: Survives reboots and DHCP renewals.
+
+**How it works:**
+1. **Configuration**: A custom file named `/mnt/nv/aftertouch.resolv.conf` is created on the device's persistent partition.
+2. **Boot Hook**: On every boot, `/mnt/nv/rc.local` checks if the system's DHCP scripts (`/etc/udhcpc.d/50default` or `/opt/Bose/udhcpc.script`) have been patched.
+3. **Surgical Patch**: If not patched, it injects a one-line check into the relevant DHCP scripts.
+4. **Resolution**: Whenever the device acquires a DHCP lease, the scripts now read your `aftertouch.resolv.conf` first, placing your DNS server at the top of `/etc/resolv.conf` while keeping all other DHCP-provided settings.
+
+**Setup:**
+1. Enable SSH via the `remote_services` USB trick.
+2. Create `/mnt/nv/aftertouch.resolv.conf` with your server details:
+   ```text
+   # Created by Aftertouch/SoundTouch-Service
+   # Priority nameserver for Bose service redirection
+   nameserver 192.168.1.XXX
+   ```
+3. Update `/mnt/nv/rc.local` with the idempotent patch:
+   ```sh
+   #!/bin/sh
+   # Aftertouch DNS hook: prioritizes our custom nameserver if it exists
+   HOOK_MARKER="/mnt/nv/aftertouch.resolv.conf"
+   if [ -f "$HOOK_MARKER" ]; then
+       # Patch 50default if it exists
+       TARGET_FILE="/etc/udhcpc.d/50default"
+       if [ -f "$TARGET_FILE" ] && ! grep -q "$HOOK_MARKER" "$TARGET_FILE"; then
+           sed -i '/echo "search \$domain"/a \        [ -f '"$HOOK_MARKER"' ] && cat '"$HOOK_MARKER"' && dns=""' "$TARGET_FILE"
+       fi
+       # Patch udhcpc.script if it exists (e.g. SoundTouch 10)
+       TARGET_SCRIPT="/opt/Bose/udhcpc.script"
+       if [ -f "$TARGET_SCRIPT" ] && ! grep -q "$HOOK_MARKER" "$TARGET_SCRIPT"; then
+           sed -i '/echo "search \$search_list # \$interface" >> \$RESOLV_CONF/a \                [ -f '"$HOOK_MARKER"' ] && cat '"$HOOK_MARKER"' >> '"\$RESOLV_CONF"' && dns=""' "$TARGET_SCRIPT"
+       fi
+   fi
+   ```
+4. Make the script executable: `chmod +x /mnt/nv/rc.local`.
+5. Reboot the speaker.
+
+### DNS Discovery Server
+
+The SoundTouch service includes a built-in DNS server specifically designed for Bose devices.
+
+#### How it Works
+When enabled, the DNS server:
+1. Receives DNS queries from migrated SoundTouch devices.
+2. **Intercepts** known Bose domains (e.g., `api.bose.com`, `streaming.bose.com`, `bmx.bose.com`) and resolves them to the AfterTouch service IP.
+3. **Logs** all other queries for discovery purposes, allowing you to identify new Bose cloud endpoints.
+4. **Forwards** unknown or non-Bose queries to the configured upstream DNS server (default: `8.8.8.8`).
+
+#### Configuration
+You can enable and configure the DNS server via the Web UI or environment variables:
+- `ENABLE_DNS_DISCOVERY=true`: Turns on the DNS server.
+- `DNS_BIND_ADDR=:53`: The port to listen on (requires root privileges for port 53).
+- `DNS_UPSTREAM=1.1.1.1`: Your preferred upstream DNS provider. **Note:** Ensure this is not set to the same address as the DNS server itself (loopback or local IP) to avoid forwarding loops. The server includes built-in loop prevention, but misconfiguration will cause forwarding to fail. DNS Discovery cannot be enabled if this setting is empty.
+
+#### Manual Discovery via DNS
+Even without migrating a device, you can use the DNS server to discover what a device is querying by manually setting your router's DNS or the device's DNS to point to the AfterTouch service.
+
+## Endpoint Mirroring & Parity Logging
+
+The SoundTouch service includes a powerful **Mirroring** feature that allows you to handle requests locally while simultaneously forwarding them to the official Bose cloud in the background. This is primarily used for maintaining long-term compatibility and verifying the accuracy of the local emulation.
+
+### How Mirroring Works
+
+When an endpoint is configured for mirroring:
+1. **GET Requests**: Handled locally first (Primary). The response is returned to the speaker immediately. In the background, the same request is sent to Bose.
+2. **POST/PUT/DELETE Requests**: Handled locally first. The service then synchronously (but without blocking the speaker's response) forwards the request to Bose to ensure the "official" account state stays in sync with your local changes (e.g., updating a preset).
+
+### Parity Logging
+
+The **Parity Logger** automatically compares the response from your local service with the one received from Bose. If it detects any discrepancies, it:
+1. Logs a warning to the console: `[PARITY] Mismatch detected for GET /...`
+2. Saves a detailed JSON report to `data/parity_mismatches/`.
+
+Each report includes the full request, both response bodies, and a summary of what differed (status codes, content types, or missing/different XML tags).
+
+### Configuration
+
+Mirroring is configured via the **Settings** tab in the Web UI or through global settings:
+- **Mirror Enabled**: Master switch for the mirroring infrastructure.
+- **Mirror Endpoints**: A list of URL path patterns to mirror. You can use wildcards (`*`) to match variable parts like account or device IDs.
+  - Example: `/streaming/account/*/device/*/recent`
+  - Example: `/accounts/*/devices/*/presets/*`
+
+Mirrored requests are also recorded in the **Interaction Log** under the category `upstream-mirror`, allowing you to see side-by-side exactly how our service's behavior compares to the official one.

+
+## HTTP Interaction Recording
+
+The service automatically records all HTTP interactions (both those handled locally and those proxied upstream) as `.http` files. These files are compatible with the [IntelliJ IDEA HTTP Client](https://www.jetbrains.com/help/idea/exploring-http-syntax.html).
+
+### Internal Paths (Excluding Traffic)
+
+To prevent internal management traffic (like the Web UI or setup API calls) from cluttering your interaction logs, you can configure **Internal Paths**. Requests matching these patterns will be processed normally but will **not** be recorded by the `RecordMiddleware`.
+
+By default, we recommend adding:
+- `/setup/*`: Management API calls
+- `/web/*`: Static Web UI resources
+- `/media/*`: Icons and static media
+
+You can configure these via the **Settings** tab in the Web UI or using the `--internal-paths` flag.
+
+### Key Features
+
+- **Session Grouping**: All interactions from a single server session are stored in a dedicated directory named `{timestamp}-{pid}`.
+- **Chronological Order**: Files are prefixed with a sequential number (e.g., `0001-`, `0002-`) to preserve the exact order of requests across the entire session.
+- **Path-Based Structure**: Recordings are organized into subdirectories based on their URL path for better discoverability.
+- **Automatic Sanitization**: Variable path segments like IP addresses, Device IDs, and Account IDs are automatically identified and replaced with placeholders (e.g., `{{ip}}`, `{{deviceId}}`). The original values are preserved as comments at the top of the recorded `.http` files for easy identification.
+- **Re-playability**: An `http-client.env.json` file is generated for each session, allowing you to re-play the recorded requests immediately in IntelliJ IDEA.
+- **Management UI**: The **5. Interactions** tab provides a built-in viewer and management tools for all recorded data.
+
+### Configuration
+
+#### Redaction
+
+By default, the service redacts sensitive information from the recorded `.http` files, including:
+- `Authorization` headers
+- `Cookie` headers
+- `X-Bose-Token` headers
+- `X-Bose-Key` headers
+- `Proxy-Authorization` headers
+
+This behavior is controlled by the `--redact-logs` flag or the `REDACT_PROXY_LOGS` environment variable.
+
+#### Custom Patterns
+
+The service uses regex patterns to identify variable segments in URL paths. These patterns are loaded from `data/patterns.json`. You can add custom patterns to this file to support additional variable segments:
+
+```json
+[
+  {
+    "name": "MyVariable",
+    "regexp": "^[0-9]{5}$",
+    "replacement": "{myVar}"
+  }
+]
+```
+
+Variables found via these patterns will be:
+1. Used as directory names in the `interactions/` folder.
+2. Parameterized as `{{myVar}}` within the `.http` files.
+3. Added to the `http-client.env.json` file with their actual values.
+
+## Persistent Data
+
+### Data Directory Structure
+
+By default, the service creates a `data/` directory in the current working directory:

+
+## Credits & Inspiration
+
+This service implementation is based on and inspired by several excellent community projects:
+
+### SoundCork
+- **Project**: [SoundCork](https://github.com/deborahgu/soundcork)  
+- **Authors**: Deborah Gu and contributors
+- **Contribution**: The architecture and service emulation approach in this Go implementation is heavily based on SoundCork's pioneering Python implementation. SoundCork provided the foundation for understanding Bose's service architecture and migration strategies.
+
+### ÜberBöse API
+- **Project**: [ÜberBöse API](https://github.com/julius-d/ueberboese-api)
+- **Author**: Julius D.
+- **Contribution**: Advanced API endpoint discovery and implementation details that helped make this service more complete and robust.
+
+We are grateful to these projects for paving the way and providing the research foundation that made this comprehensive service implementation possible.
+
+## Advanced Usage
+
+### Custom Service Integration
+
+```go
+// Example: Custom BMX service handler
+package main
+
+import (
+    "net/http"
+    "github.com/go-chi/chi/v5"
+)
+
+func customBMXHandler(w http.ResponseWriter, r *http.Request) {
+    // Custom BMX service logic
+    w.Header().Set("Content-Type", "application/json")
+    w.Write([]byte(`{"custom": "service"}`))
+}
+
+func main() {
+    r := chi.NewRouter()
+    r.Get("/bmx/custom/endpoint", customBMXHandler)
+    http.ListenAndServe(":8000", r)
+}
+```
+
+### Integration with Home Assistant
+
+```yaml
+# configuration.yaml
+soundtouch:
+  - host: 192.168.1.100
+    port: 8090
+    name: "Living Room Speaker"
+    
+rest:
+  - resource: "http://localhost:8000/devices"
+    scan_interval: 60
+    sensor:
+      - name: "SoundTouch Devices"
+        value_template: "{{ value_json | length }}"
+```
+
+### Monitoring & Alerting
+
+```bash
+# Health check script
+#!/bin/bash
+response=$(curl -s -o /dev/null -w "%{http_code}" http://localhost:8000/health)
+if [ $response != "200" ]; then
+    echo "SoundTouch service is down!" | mail -s "Alert" admin@example.com
+fi
+```
+
+## Security Considerations
+
+- **Network Security**: The service binds to all interfaces by default. Consider using `BIND_ADDR=127.0.0.1` for localhost-only access.
+- **SSH Access**: Migration requires SSH access to devices. Ensure your network security policies allow this.
+- **Proxy Logging**: Disable `REDACT_PROXY_LOGS` only in development environments.
+- **Data Protection**: The data directory contains device configurations and usage patterns. Secure appropriately.
+
+## Performance Tuning
+
+### Resource Usage
+- **Memory**: ~50MB baseline + ~5MB per discovered device
+- **CPU**: Minimal during steady state, ~10% during discovery/migration
+- **Disk**: ~1MB per device configuration + logs
+
+### Scaling Considerations
+```bash
+# For many devices, increase discovery interval
+DISCOVERY_INTERVAL=10m soundtouch-service
+
+# For high-traffic environments, consider reverse proxy
+nginx -> soundtouch-service instances
+```

+### Bose Cloud Shutdown: Survival Guide for SoundTouch
+
+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.
+
+This guide explains how to set up the `soundtouch-service` to run your devices independently of Bose's servers.
+
+---
+
+### Supported Use Cases
+
+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.
+
+---
+
+### Setup Steps
+
+To set up your SoundTouch system for local-only operation, follow these steps:
+
+#### 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.
+
+```bash
+# Install the service
+go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-service@latest
+
+# Start the service (defaults to http://localhost:8000)
+soundtouch-service
+```
+
+#### 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/`
+
+*Note: The service also supports a `/web/` path for management.*
+
+#### 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.
+
+---
+
+### 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.
+
+---
+
+### 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:
+
+*   `bmx.bose.com`
+*   `streaming.bose.com`
+*   `updates.bose.com`
+*   `stats.bose.com`
+*   `content.api.bose.io`
+
+*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.*

+
+**Symptoms:**
+```
+GET /streaming/account/3230304/device/A81B6A536A98/presets
+→ 500 Internal Server Error
+→ Log: "open .../devices/A81B6A536A98/Presets.xml: no such file or directory"
+```
+
+**Cause:** The service uses MAC addresses in API requests but stores files using device serial numbers. A mapping system resolves MAC addresses to serial numbers automatically.
+
+**Quick Solutions:**
+
+1. **Restart the service** (mappings are created at startup):
+```bash
+sudo systemctl restart soundtouch-service
+```
+
+2. **Check device directory structure**:
+```bash
+# Files should be stored by serial number, not MAC
+ls data/accounts/3230304/devices/
+# Should show: I6332527703739342000020/ (not A81B6A536A98/)

+# /power_on Implementation Guide
+
+## Overview
+
+This guide provides detailed technical specifications for implementing `/power_on` endpoint enhancements to reduce network dependency and improve device lifecycle management in the SoundTouch service.
+
+## Current /power_on Handler Analysis
+
+### Existing Implementation
+Located in `pkg/service/handlers/handlers_marge.go`:
+
+```go
+func (s *Server) HandleMargePowerOn(w http.ResponseWriter, r *http.Request) {
+    body, err := io.ReadAll(r.Body)
+    if err != nil {
+        log.Printf("[Marge] Failed to read power_on body: %v", err)
+        w.WriteHeader(http.StatusOK)
+        return
+    }
+
+    var req models.CustomerSupportRequest
+    if err := xml.Unmarshal(body, &req); err != nil {
+        log.Printf("[Marge] Failed to parse power_on body: %v", err)
+        // Fallback to remote address
+        if host, _, err := net.SplitHostPort(r.RemoteAddr); err == nil {
+            go s.PrimeDeviceWithSpotify(host)
+        }
+        w.WriteHeader(http.StatusOK)
+        return
+    }
+
+    deviceID := req.Device.ID
+    deviceIP := req.DiagnosticData.DeviceLandscape.IPAddress
+
+    log.Printf("[Marge] Device %s powered on (IP: %s)", deviceID, deviceIP)
+
+    if deviceIP != "" {
+        go s.PrimeDeviceWithSpotify(deviceIP)
+    } else {
+        // Fallback to remote address
+        if host, _, err := net.SplitHostPort(r.RemoteAddr); err == nil {
+            go s.PrimeDeviceWithSpotify(host)
+        }
+    }
+
+    w.WriteHeader(http.StatusOK)
+}
+```
+
+**Current Limitations:**
+- Only extracts basic device ID and IP
+- No device state management
+- No data persistence
+- No response payload
+- Limited to Spotify priming
+
+## Enhanced Implementation Design
+
+### 1. Extended Data Models
+
+#### Enhanced Power-On Request Model
+```go
+// PowerOnRequest represents the enhanced power_on request structure
+type PowerOnRequest struct {
+    XMLName        xml.Name `xml:"device-data"`

+    IPAddress          string   `xml:"ip-address"`
+    ConnectionType     string   `xml:"network-connection-type"`
+}
+```
+
+#### Enhanced Response Model
+```go
+// PowerOnResponse represents the response sent back to the device
+type PowerOnResponse struct {
+    XMLName              xml.Name              `xml:"power-on-response"`
+    Status               string                `xml:"status"`
+    DeviceID             string                `xml:"device-id"`

+    Key      string `xml:"key"`
+    Value    string `xml:"value"`
+    Priority int    `xml:"priority,attr"`
+}
+
+type MigrationInstruction struct {
+    Method    string            `xml:"method,attr"`
+    TargetURL string            `xml:"target-url"`
+    ProxyURL  string            `xml:"proxy-url,omitempty"`
+    Options   map[string]string `xml:"options>option"`
+}
+```
+
+### 2. Enhanced PowerOn Handler
+
+```go
+// HandleMargePowerOnEnhanced processes power_on requests with full device lifecycle management
+func (s *Server) HandleMargePowerOnEnhanced(w http.ResponseWriter, r *http.Request) {
+    startTime := time.Now()
+    
+    // Parse the power_on request
+    powerOnReq, err := s.parsePowerOnRequest(r)
+    if err != nil {
+        s.handlePowerOnError(w, r, "Failed to parse request", err)
+        return
+    }
+
+    // Process device information
+    deviceInfo, isNewDevice, err := s.processDeviceFromPowerOn(powerOnReq)
+    if err != nil {
+        s.handlePowerOnError(w, r, "Failed to process device", err)
+        return
+    }
+
+    // Build response based on device state
+    response := s.buildPowerOnResponse(deviceInfo, isNewDevice, powerOnReq)
+
+    // Log the interaction
+    s.logPowerOnInteraction(deviceInfo, powerOnReq, response, startTime)
+
+    // Send response
+    if err := s.sendPowerOnResponse(w, response); err != nil {
+        log.Printf("[PowerOn] Failed to send response for device %s: %v", deviceInfo.DeviceID, err)
+    }
+}
+```
+
+### 3. Device Processing Logic
+
+```go
+// processDeviceFromPowerOn handles device identification and data updates
+func (s *Server) processDeviceFromPowerOn(req *PowerOnRequest) (*models.ServiceDeviceInfo, bool, error) {
+    deviceMAC := req.Device.ID

+
+### 9. Logging and Monitoring
+
+```go

+## Testing Strategy
+
+### 1. Unit Tests
+```go
+func TestHandleMargePowerOnEnhanced(t *testing.T) {
+    tests := []struct {
+        name           string
+        requestBody    string

+            // Test implementation
+        })
+    }
+}
+```
+
+### 2. Integration Tests
+```go
+func TestPowerOnDeviceLifecycle(t *testing.T) {
+    // Test complete device lifecycle through power_on events
+    // 1. New device power_on
+    // 2. Device registration
+    // 3. Configuration changes
+    // 4. Migration
+    // 5. Subsequent power_on events
+}
+```
+
+### 3. Load Testing
+```go
+func BenchmarkPowerOnProcessing(b *testing.B) {
+    // Benchmark power_on processing performance
+    // Test concurrent device registrations
+    // Measure response times
+}
+```
+
+## Deployment Strategy
+
+### Phase 1: Parallel Implementation
+- Implement enhanced handler alongside existing handler
+- Use feature flag to control which handler processes requests
+- Maintain full backward compatibility
+
+### Phase 2: Gradual Rollout
+- Enable enhanced processing for subset of devices
+- Monitor performance and error rates
+- Collect metrics on data completeness
+
+### Phase 3: Full Migration
+- Default to enhanced processing for all devices
+- Remove legacy fallbacks
+- Optimize performance based on production data
+
+## Monitoring and Metrics
+
+### Key Metrics to Track
+- Power-on event frequency per device
+- New device registration rate via power_on
+- Migration success rate via power_on response
+- Response time distribution
+- Error rates and types
+- Data completeness metrics
+
+### Alerting Thresholds
+- Power-on processing failures > 5%
+- Average response time > 2 seconds
+- New device registration failures > 1%
+- Migration instruction delivery failures > 2%
+
+## Security Considerations
+
+### Input Validation
+- XML parsing security (prevent XXE attacks)
+- Device ID format validation
+- IP address validation
+- Request size limits
+
+### Authentication
+- Device authentication via MAC address verification
+- Request signing (if available)
+- Rate limiting per device/IP
+
+### Data Privacy
+- Sensitive data handling in diagnostic information
+- Logging data retention policies
+- Compliance with data protection regulations

+# SCMUDC Events Analysis
+
+## Overview
+
+SCMUDC (Sound Control Management Usage Data Collection) events are telemetry data sent from SoundTouch devices to `events.api.bosecm.com` via `/v1/scmudc/{deviceId}` endpoints. These events track user interactions and device behaviors for analytics and monitoring.
+
+## Event Origins
+
+Analysis of recorded interactions reveals three distinct origins for device events:
+
+### 1. `"gabbo"` - SoundTouch App (Mobile/Desktop)
+- **Source**: Remote control via SoundTouch mobile/desktop applications
+- **Frequency**: Highest (primary control method)
+- **Event Types**: User-initiated actions through app interface
+- **Button Abstraction**: App UI elements (not physical buttons)
+
+**Common Events**:
+- `power-pressed` → Power on/off via app
+- `play-pressed` → Play control
+- `pause-pressed` → Pause control  
+- `skip-forward-pressed` → Next track
+- `stop-pressed` → Stop playback
+
+### 2. `"console"` - Device Hardware Controls
+- **Source**: Physical buttons and controls on the speaker device
+- **Frequency**: Lower (secondary control method)
+- **Event Types**: Direct hardware interaction
+- **Physical Controls**: Actual buttons, knobs, or touch interfaces on device
+
+**Common Events**:
+- `preset-pressed` → Physical preset buttons (PRESET_1, PRESET_5, etc.)
+- `power-pressed` → Hardware power button
+
+### 3. `"device"` - Internal System Actions
+- **Source**: Device's internal software systems
+- **Frequency**: Automatic responses to user actions
+- **Event Types**: System-generated events, content playback
+- **Rich Content**: Base64-encoded XML with detailed metadata
+
+**Common Events**:
+- `play-item` → Automatic content playback responses
+- `preset-assigned` → System preset assignments
+
+## Event Data Structure
+
+### Standard Button Events (gabbo/console)
+```json
+{
+  "data": {
+    "buttonId": "POWER|PLAY|PAUSE|PRESET_5|etc",
+    "origin": "gabbo|console"
+  },
+  "type": "power-pressed|play-pressed|pause-pressed|preset-pressed|etc"
+}
+```
+
+### Device Content Events
+```json
+{
+  "data": {
+    "contentItem": "PD94bWwgdmVyc2lvbj0...", // Base64-encoded XML
+    "origin": "device",
+    "preset": "none|P1|P5|etc"
+  },
+  "type": "play-item|preset-assigned"
+}
+```
+
+## Content Item Structure
+
+Device events include Base64-encoded XML with rich content metadata:
+
+```xml
+<ContentItem source="SPOTIFY" type="tracklisturl" 
+             location="/playback/container/c3BvdGlmeTpwbGF5bGlzdDox..." 
+             sourceAccount="gesellix" isPresetable="true">
+    <itemName>Billie Eilish - bad guy (instrumental version)</itemName>
+    <containerArt>https://i.scdn.co/image/ab67616d0000b273...</containerArt>
+</ContentItem>
+```
+
+**Key Fields**:
+- `source`: Music service (SPOTIFY, PANDORA, etc.)
+- `itemName`: Track/playlist/station name
+- `sourceAccount`: User account on the service
+- `location`: Service-specific content identifier
+- `containerArt`: Album/playlist artwork URL
+- `isPresetable`: Whether content can be saved as preset
+
+## Usage Patterns
+
+### Control Method Preferences
+1. **Primary**: SoundTouch App (`gabbo`) - Most frequent interactions
+2. **Secondary**: Device Hardware (`console`) - Occasional direct control
+3. **Automatic**: Internal System (`device`) - Background responses
+
+### Event Flow
+1. User triggers action via app or hardware
+2. Device processes request and begins playback
+3. Device sends content event with full metadata
+4. System continues tracking playback state
+
+## Telemetry Insights
+
+### User Behavior Analytics
+- **Interface Preference**: App vs. hardware control usage ratios
+- **Feature Usage**: Most/least used controls and functions
+- **Content Patterns**: Music service preferences, playlist usage
+
+### Device Health Monitoring
+- **Interaction Frequency**: Normal vs. abnormal usage patterns
+- **Error Detection**: Failed commands or unusual event sequences
+- **Performance**: Response times between user action and system response
+
+### Service Integration Analysis
+- **Music Services**: Spotify dominance, other service usage
+- **Account Mapping**: User accounts across different services
+- **Content Types**: Music vs. radio vs. podcast preferences
+
+## Data Quality Notes
+
+- All events include comprehensive device information (deviceID, serialNumber, softwareVersion)
+- Timestamps include both UTC time and device monotonic time
+- Events are batched and sent with consistent protocol versioning
+- Content metadata is rich and includes artwork URLs for UI enhancement
+
+## Security Considerations
+
+- Events include user account information and listening habits
+- Device serial numbers and unique identifiers are transmitted
+- Content location data could reveal usage patterns
+- Data should be handled according to privacy regulations
+
+## Technical Implementation Notes
+
+- Endpoint: `POST /v1/scmudc/{deviceId}`
+- Protocol Version: 3.1 (current)
+- Encoding: JSON with Base64-encoded XML payloads
+- Authentication: Bearer token authorization
+- Content-Type: `text/json; charset=utf-8`
