Improve parity with upstream Bose services

- Reorder header setting and WriteHeader calls in HandleMargeAddRecent to ensure Content-Type is correctly sent.
- Update HandleMargeAddRecent to explicitly use 201 Created status code.
- Improve parity mismatch logging to correctly capture headers from local handlers.
- Enhance mirroring logic to support local testing of upstream parity.

+# 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
+### POST /v1/scmudc/A81B6A536A98
+POST /v1/scmudc/A81B6A536A98

+
+> {% 
+    // Response: 200 OK
+%}
+```
+
+**Mirror Recording** (missing body):
+```http
+### POST /v1/scmudc/A81B6A536A98
+POST /v1/scmudc/A81B6A536A98

+
+
+
+> {% 
+    // Response: 200 OK
+    // Headers:
+    // X-Proxy-Origin: upstream-mirror
+%}
+```
+
+### 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)
+┌─────────────────┐              │
+│   Middleware    │◀─────────────┘
+│     Chain       │
+└─────────┬───────┘
+          │
+      ┌───▼────┐ ┌─────────┐ ┌──────────────┐
+      │ Local  │ │ Mirror  │ │ Recording    │
+      │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
+    buf.WriteString("> {% \n")
+    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)
+        }
+    }
+    
+    buf.WriteString("%}\n\n")
+    
+    if len(res.Body) > 0 {
+        buf.WriteString("/*\n")
+        buf.Write(res.Body)
+        buf.WriteString("\n*/\n")
+    } else {
+        buf.WriteString("// [Binary response body: 0 bytes]\n")
+    }
+    
+    // Write to file
+    return r.writeToFile(buf.Bytes(), req, res)
+}
+```
+
+## Migration Strategy
+
+### Phase 1: Introduce Snapshot System
+- Add SnapshotMiddleware as first middleware
+- Maintain existing recording system for compatibility
+- Gradual migration of recording points
+
+### Phase 2: Update Mirror System
+- Modify MirrorMiddleware to use snapshots
+- Ensure mirror requests use snapshot data
+- Test parity between old and new systems
+
+### Phase 3: Consolidate Recording
+- Replace existing recording middleware
+- Unified recording system using context-bound snapshots
+- Remove duplicate body reading code
+
+### Phase 4: Cleanup
+- Remove legacy recording code
+- Optimize memory usage with sync.Pool
+- Performance validation on target hardware (Pi Zero)
+
+## Benefits
+
+1. **Zero Extra Disk IO**: Protecs MicroSD by avoiding snapshot disk persistence
+2. **Memory Efficiency**: Natural lifecycle tied to Request Context
+3. **Data Integrity**: Request data is captured once and remains immutable
+4. **Consistency**: All consumers use identical request data
+5. **Traceability**: Clear lineage from original request to all recordings
+6. **Performance**: Reduces duplicate body reads and re-cloning
+
+## Implementation Considerations
+
+### Memory Management
+- Use `sync.Pool` for byte buffers
+- Strict size limits on captured bodies
+- Rely on GC for snapshot cleanup
+
+### Performance Impact
+- Single body read vs multiple reads (net positive)
+- Memory overhead for snapshot storage (manageable)
+- Context propagation overhead (minimal)
+
+### Backward Compatibility
+- Maintain existing .http file format
+- Preserve existing API contracts
+- Gradual migration path
+
+## Testing Strategy
+
+### Unit Tests
+- Snapshot creation and immutability
+- Response recording accuracy
+- Memory cleanup verification
+
+### Integration Tests
+- End-to-end request/response recording
+- Mirror functionality with snapshots
+- Parity validation between old/new systems
+
+### Performance Tests
+- Memory usage comparison
+- Throughput impact analysis
+- Large request body handling
+
+## Future Enhancements
+
+1. **Compression**: Compress stored snapshots for memory efficiency
+2. **Streaming**: Support for streaming request/response bodies
+3. **Filtering**: Selective snapshot creation based on patterns
+4. **Analytics**: Request/response analysis and metrics
+5. **Export**: Snapshot export for debugging and analysis
+
+## Conclusion
+
+This snapshot-based approach provides a robust foundation for reliable request recording while solving the current issues with body consumption and data inconsistency. The phased implementation ensures minimal disruption while delivering immediate benefits.

+# Spotify OAuth Integration
+
+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

+    
+    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)

+    
+    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)
+

+    
+    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.

+# 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.

+# 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

+## 🏗️ **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)

+#### 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.

+**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/)
+```
+
+3. **Verify DeviceInfo.xml contains MAC address**:
+```bash
+cat data/accounts/3230304/devices/*/DeviceInfo.xml | grep macAddress
+```
