feat(export): encrypted diagnostic report for issue reporting

Adds a "Download diagnostic report" button on the Health tab that
produces an age-encrypted .age file the user can attach to a GitHub
issue without exposing sensitive data.

Archive contents (tar.gz, then age-encrypted with the maintainer's
SSH ed25519 public key):
- diagnostic.json         structured health/device summary (no secrets)
- datastore/…/*.xml       raw on-disk XML verbatim for diff vs HTTP
- http/service/…          live service HTTP responses per account/device
- http/speaker/…          live speaker API responses (port 8090)
- ssh/speaker/…           CA bundles + logread (last 20 min, 127.0.0.1
                          filtered) + dmesg fetched via SSH
- system/ca.pem           service CA cert
- system/resolv.conf      host DNS resolver config
- settings.json           service settings (OAuth secrets redacted)
- env.txt                 filtered process environment
- logs/service.txt        in-memory service log buffer

Supporting tooling:
- scripts/setup-diagnostic-key.sh  one-time SSH key-pair generation
- scripts/decrypt-diagnostic.go    go run helper for maintainer decryption
- keys/public/diagnostic.pub       committed public key (matches github.com/gesellix.keys)
- docs/DIAGNOSTIC-EXPORT.md        maintainer setup + user workflow guide
- docs/concepts/ENCRYPTED-EXPORT.md  research notes and architecture rationale

+repository. Read it before touching code.
+
+## What this project is
+
+Go library and toolset for controlling Bose SoundTouch speakers via
+the local network API, plus a local cloud-service emulator. Bose
+discontinued the SoundTouch cloud — this project keeps existing
+speakers usable without it.
+
+**Module:** `github.com/gesellix/bose-soundtouch`
+
+Key binaries:
+
+- `soundtouch-cli` — command-line control of one or more speakers
+  (status, play, presets, groups, migration, …).
+- `soundtouch-service` — replacement for `streaming.bose.com`
+  and the `bmx` services, default port `8000`.
+- `soundtouch-web` — Web UI for Radio browsing and device control.
+- `soundtouch-backup` — Helper for on-device backup and restore.
+
+Per-session pickup notes live in two local files at the repo root (they are `.gitignore`d and only exist if created during a session):
+
+- `NEXT.md` — current "pick up here" log of open items.
+- `DONE.md` — archive of recently resolved items.
+
+## How a new session should start
+
+1. Read this file.
+2. Read `NEXT.md` if it's present — that's where running context lives.
+3. Skim `README.md` for the user-facing pitch.
+4. Skim `docs/` for the area you're touching. Long-form notes
+   (analysis, guides, troubleshooting) live there, not in the code.
+5. Run `make check` once to confirm the local environment compiles,
+   vets, and tests cleanly.
+
+## Build, test, run
+
+```bash
+# Build
+make build          # All binaries
+make build-cli      # Just CLI
+make build-service  # Just service
+make build-web      # Just web UI
+make build-all      # Cross-platform builds (Linux, macOS, Windows)
+make install        # Install to $GOPATH/bin
+
+# Quality
+make test           # Unit tests
+make test-coverage  # Coverage reports
+make check          # fmt + vet + test
+make lint           # golangci-lint
+make update-static-deps # Update frontend libraries (preact, htm) from node_modules
+
+# Automation
+A GitHub Action automatically runs `make update-static-deps` on Dependabot PRs that modify `package.json` to keep the vendored `.js` files in sync. Note: This requires `npm` to be installed.
+
+# Development
+make dev-service    # Run local service on port 8000
+make dev-discover   # Discover devices on the LAN
+make dev-info HOST=<ip>  # Get device info
+
+# Docker
+make docker-build
+make docker-run-host
+```
+
+**Pre-push quality gate:** `make lint` (golangci-lint) must be clean
+before `git push`. CI runs it on every PR; running it locally first
+saves a round-trip. `make check` covers `lint` is its own target —
+combine as needed.
+
+## Integration tests
+
+The `.http` integration tests under `tests/integration/http-client/`
+run via `make test-http-client`, which spins up the service plus
+support mocks (`spotify-mock`, `amazon-mock`) using
+`docker-compose.yml` + `docker-compose.ci.yml`, executes the suite
+through the JetBrains HTTP client image, then tears the stack down.
+Requires Docker.
+
+The compose CI override mounts `tests/integration/testdata/` into the
+service container as its persistent data dir. That directory is
+listed in `tests/.gitignore` — it's local developer state, not source.
+
+**Treat the testdata dir as debug evidence, not disposable scratch.**
+When a fixture or schema change makes the old state stale (e.g.
+post-anonymisation, the previous run's IPs no longer match the
+assertions), don't `rm -rf` it — archive it:
+
+```bash
+make test-http-client-rotate   # renames testdata/ → testdata_<timestamp>/
+make test-http-client          # fresh run on a clean slate
+```
+
+The rotate target is non-destructive (it moves, never deletes) and
+opt-in (no other target invokes it). Old archives stay around for
+retrospective diffing whenever something goes sideways.

+
+## Key technologies
+
+- **Go 1.26.3+**
+- **chi v5** — HTTP router
+- **gorilla/websocket** — WebSocket for real-time events
+- **hashicorp/mdns** — mDNS device discovery
+- **miekg/dns** — DNS operations and a custom DNS server
+- **urfave/cli/v2** — CLI framework
+
+## Architecture notes
+
+- `pkg/client` is the core library for device API calls (HTTP + WebSocket).
+- `pkg/service` is the local cloud replacement; routes wire to the
+  handlers in `pkg/service/handlers/` via chi middleware.
+- Discovery supports both mDNS and UPnP/SSDP behind a unified interface.
+- The SoundTouch Web API uses XML on the wire; internal service-to-service
+  messages use JSON.
+- Tests cover unit, integration, parity (local vs. official Bose API
+  recordings), and regression. Reproducer tests should be refactored
+  into permanent regression or documentation tests rather than deleted.
+
+## Load-bearing gotchas
+
+### `ETag` header literal must stay capitalised
+
+Bose speakers emit the response header with exact capitalisation
+`ETag`. Go's `http.Header.Set` canonicalises to `Etag` (lowercase `t`).
+Real speakers parse strictly — `Etag` is rejected. The codebase
+deliberately bypasses the canonicalisation path; do **not** rewrite
+the string literal `"ETag"` to `"Etag"` anywhere in `pkg/service/handlers/`
+or in tests.
+
+The contrast is encoded in two named constants in
+`pkg/service/handlers/handlers_etag_test.go`:
+
+```go
+const normalizedEtag    = "Etag" // what http.Header.Set produces
+const caseSensitiveETag = "ETag" // what the speaker actually expects
+```
+
+Linter suppressions on the canonical-header check live alongside the
+test code. Static-analysis warnings about `"ETag"` are expected;
+don't "fix" them.
+
+### Destructive git or filesystem actions need explicit confirmation
+
+`git reset --hard`, `git checkout` that would overwrite local changes,
+`git clean -fd`, `rm -rf` on non-build paths, `git stash drop` — all
+should be proposed in writing with their consequences before running,
+unless the user has already authorised that specific action in this
+session. Prefer reversible alternatives (`git stash` over
+`git reset --hard`).
+
+## What never goes into this repo
+
+This repository is public. The following must never be committed:
+
+- **Real LAN IPs** of personal networks. Use RFC-5737 documentation
+  ranges in examples and fixtures: `192.0.2.0/24`, `198.51.100.0/24`,
+  `203.0.113.0/24`.
+- **Real MAC addresses** or speaker device IDs from anyone's actual
+  hardware. Use `AA:BB:CC:DD:EE:FF` or `DEVICEID01` style placeholders.
+- **Bose account IDs**, serial numbers, or tokens belonging to anyone
+  other than the committer's own test devices — and even those should
+  be sanitised before publication when feasible.
+- **Bose firmware binaries, NAND dumps, or decompiled Bose code.**
+- **Wi-Fi SSIDs or credentials**, captured or otherwise.
+- **Network captures, traces, or logs** that include data from
+  accounts or devices other than your own test hardware.
+- **Personal identifiers**: real names of speakers ("LivingRoom",
+  custom device names), private email addresses, household member
+  names visible in source IDs.
+
+If you spot any of the above already in the tree, treat it as a
+sanitisation task: stop, flag it to the maintainer, propose a
+remediation commit before continuing.
+
+## Disclaimers
+
+"SoundTouch" and "Bose" are registered trademarks of Bose Corporation.
+This project is an unofficial, community-built effort, not affiliated

+
+## Communication style
+
+When working with a human user in this repo:
+
+- **Prioritise direct answers** to the question being asked, even when
+  it sits outside the current task or project context. Don't divert
+  back to whatever you were doing when the user asks something else.
+- **Don't substitute assumptions for real information.** When something
+  is unclear, ask or check, rather than guessing and proceeding.
+
+These principles also apply to other AI assistants pointed at this
+repo. Tool-specific config dirs (e.g. `.junie/`, `.claude/`) should
+defer to this file as the source of truth instead of carrying their
+own copies.

+Bose is shutting down SoundTouch cloud services on **May 6, 2026**. After that, music service browsing, preset sync, and the official SoundTouch app stop working. This toolkit lets you keep your speakers fully functional.
 
-## Quick Start
+See the [Survival Guide](https://gesellix.github.io/Bose-SoundTouch/guides/SURVIVAL-GUIDE.html) for the full picture.
 
-### Installation
+---
+
+## Tools
+
+### soundtouch-service — AfterTouch
+
+A local server that replaces the Bose cloud ("AfterTouch"). Once your speaker is redirected to it, you have full control without any Bose cloud dependency. The built-in web UI at `http://localhost:8000` handles all setup — no config files needed to get started.
+
+If you don't want to run a server for this - no problem. The service is small enough to run on the SoundTouch itself. See the [On-Device Installer](./scripts/on-device-install/README.md) for instructions.
+
+**Two scenarios:**
+
+**Before shutdown — migrate your existing setup**
+While the Bose cloud is still running, use `soundtouch-backup` to save your account data. The local service web UI then helps with the migration so your speaker keeps its presets and credentials.
+
+**After shutdown or factory reset — start fresh**
+Create a local account, configure your speakers, and start using them immediately. No Bose infrastructure required.
+
+**Redirecting your speaker**
+
+The service needs a stable address on your local network (e.g. `soundtouch.fritz.box` or `soundtouch.local`). The speaker must then be redirected to resolve the Bose cloud hostnames to that address. Two supported methods:
+
+| Method       | How it works                        | Notes                                                        |
+|--------------|-------------------------------------|--------------------------------------------------------------|
+| XML redirect | Upload a config XML via the Web API | Surgical; covers only registered endpoints; best for testing |
+| DNS/DHCP     | Serve custom DNS on your network    | Covers all devices at once; requires port 53 and TLS         |
+
+The web UI walks you through each method. DNS redirect requires HTTPS — the service manages its own CA certificate and the web UI guides you through trusting it on each speaker.
+
+> **Note:** A hosts-file method (direct SSH edits to `/etc/hosts`) also exists in the codebase but is deprecated and not exposed in the web UI.
+
+**Enabling SSH via USB stick**
+
+Some setup steps require SSH access to the speaker. Enable it once per device: create a file named `remote_services` on a FAT-formatted USB drive (the drive may need its bootable flag set — see [SoundCork issue #172](https://github.com/deborahgu/soundcork/issues/172)), and insert it while the speaker is powered on. After reboot, root SSH is available with no password.
+
+See [Device Initial Setup](https://gesellix.github.io/Bose-SoundTouch/guides/DEVICE-INITIAL-SETUP.html) and [Migration Guide](https://gesellix.github.io/Bose-SoundTouch/guides/MIGRATION-GUIDE.html) for step-by-step instructions.
+
+---
+
+### soundtouch-backup
+
+Backs up your Bose cloud account (presets, paired devices, music sources) and each speaker's local state before the shutdown. Run `soundtouch-backup all` to capture everything in one step; it authenticates with the Bose cloud, then polls each paired speaker over the local network.
+
+See the [soundtouch-backup README](cmd/soundtouch-backup/README.md) for usage.
+
+---
+
+### soundtouch-cli
+
+Command-line control of any SoundTouch device: play/pause/volume, presets, source selection, multiroom zones, device discovery, and more. Works entirely over the local network — no cloud dependency. Well-suited for scripting and home automation.
+
+See the [CLI Reference](https://gesellix.github.io/Bose-SoundTouch/guides/CLI-REFERENCE.html) for full usage.
+
+---
+
+### soundtouch-web
+
+A standalone web UI for device control — play, pause, volume, preset selection, real-time status — served from a local Go binary. Complements `soundtouch-service` when you want a dedicated device-control interface separate from the setup/admin UI.
+
+See the [soundtouch-web README](cmd/soundtouch-web/README.md) for usage.
+
+---
+
+### Go library
+
+`pkg/client` provides a Go API for all SoundTouch device endpoints: media control, volume, presets, sources, zones, real-time WebSocket events, and device discovery. Use it to build your own integrations.

-## SoundTouch End of Life Notice
-
-**Important:** Bose has announced that [SoundTouch cloud support will end on May 6, 2026](https://www.bose.com/soundtouch-end-of-life).
-
-**What will continue to work:**
-- ✅ Local API control (this library's primary functionality)
-- ✅ Bluetooth, AirPlay, Spotify Connect, and AUX streaming
-- ✅ Remote control features (Play, Pause, Skip, Volume)
-- ✅ Multiroom grouping
-
-**What will stop working:**
-- ❌ Cloud-based preset sync between devices and SoundTouch app
-- ❌ Browsing music services directly from the SoundTouch app
-- ❌ Cloud-based features and updates
-
-**What continues to work:**
-- ✅ Local preset management via this API client (store, select, remove)
-- ✅ Direct content playback (stations, playlists, etc.)
-
-This Go library will continue to work as it uses the local Web API for direct device control, which is unaffected by the cloud service discontinuation. The local preset management functionality implemented in this library (discovered through the [SoundTouch Plus Wiki](https://github.com/thlucas1/homeassistantcomponent_soundtouchplus/wiki/SoundTouch-WebServices-API)) provides an alternative to the cloud-based preset features that will be discontinued.
-
-**Community Alternatives**: See the [Related Projects](#related-projects) section below for additional tools like SoundCork that provide cloud service alternatives and the SoundTouch Plus project that offers comprehensive Home Assistant integration.
-

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

+| `cloud/full.xml`         | `GET /streaming/account/{id}/full` (may overlap with the above; skipped if 4xx) |
+
+---
+
+### Local backup
+
+Backs up each speaker over its HTTP API on port 8090. With `--ssh`, also captures key filesystem files via SSH.
+
+```bash
+# Auto-discover all speakers on the local network
+soundtouch-backup local
+
+# Specific speaker
+soundtouch-backup local --host 192.0.2.11
+
+# Multiple speakers
+soundtouch-backup local --host 192.0.2.11 --host 192.0.2.10
+
+# Include SSH filesystem backup
+soundtouch-backup local --ssh
+
+# Longer discovery window on busy networks
+soundtouch-backup local --discover-timeout 10s
+```
+
+**Flags**
+
+| Flag                 | Short | Default                               | Description                                      |
+|----------------------|-------|---------------------------------------|--------------------------------------------------|
+| `--host`             | `-H`  | —                                     | Speaker host/IP, repeatable (`$SOUNDTOUCH_HOST`) |
+| `--port`             | `-p`  | `8090`                                | Speaker HTTP port (`$SOUNDTOUCH_PORT`)           |
+| `--discover`         | `-d`  | auto                                  | Force mDNS/UPnP discovery                        |
+| `--discover-timeout` |       | `5s`                                  | Discovery timeout                                |
+| `--ssh`              |       | on                                    | Also capture filesystem files via SSH            |
+| `--output`           | `-o`  | `soundtouch-backup-YYYY-MM-DD.tar.gz` | Output archive path                              |
+| `--format`           |       | `tar.gz`                              | Archive format: `tar.gz` or `zip`                |
+
+**What gets fetched via HTTP**
+
+| File                | Device endpoint |
+|---------------------|-----------------|
+| `info.xml`          | `/info`         |
+| `name.xml`          | `/name`         |
+| `presets.xml`       | `/presets`      |
+| `sources.xml`       | `/sources`      |
+| `now_playing.xml`   | `/now_playing`  |
+| `volume.xml`        | `/volume`       |
+| `bass.xml`          | `/bass`         |
+| `balance.xml`       | `/balance`      |
+| `capabilities.xml`  | `/capabilities` |
+| `network_info.xml`  | `/networkInfo`  |
+| `clock_display.xml` | `/clockDisplay` |
+| `zone.xml`          | `/getZone`      |
+
+Endpoints that return HTTP 4xx (not supported on the device model) are silently skipped.
+
+**What gets fetched via SSH** (`--ssh`)
+
+SSH connects as `root@<host>:22` with an empty password, which is the default for SoundTouch firmware.
+
+Individual files:
+
+| Remote path               | Notes                                      |
+|---------------------------|--------------------------------------------|
+| `/etc/hosts`              | DNS redirect state                         |
+| `/etc/resolv.conf`        | DNS resolver configuration                 |
+| `/etc/remote_services`    | Service registration (post-migration only) |
+| `/mnt/nv/remote_services` | Alternative location for remote services   |
+
+Directories (all regular files recursively):
+
+| Remote path                      | Contents                                                                   |
+|----------------------------------|----------------------------------------------------------------------------|
+| `/opt/Bose/etc/`                 | Full Bose configuration directory, including `SoundTouchSdkPrivateCfg.xml` |
+| `/mnt/nv/BoseApp-Persistence/1/` | Persisted app state                                                        |
+
+Missing files and directories are silently skipped with a `⚠` warning.
+
+---
+
+## Archive structure
+
+Both subcommands write into a single dated archive:
+
+```
+soundtouch-backup-2026-05-02/
+├── cloud/
+│   ├── emailaddress.xml
+│   ├── devices.xml

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

+# SoundTouch Web Implementation
+
+## Overview
+
+The `soundtouch-web` tool provides a modern single-page application (SPA) for controlling Bose SoundTouch devices. Built with a JSON API backend and client-side JavaScript rendering, it offers superior performance and eliminates template rendering issues.
+
+## Architecture
+
+### Single-Page Application Design
+
+The architecture eliminates Go template dependencies and provides:
+- **JSON API Backend**: Pure Go server returning only JSON responses
+- **Client-Side Rendering**: JavaScript handles all HTML generation
+- **WebSocket Real-time**: Bi-directional communication for live updates
+- **Better Performance**: No server-side template processing
+- **Easier Development**: Clear separation of frontend/backend concerns
+
+### Core Components
+
+#### 1. Main Application (`main.go`)
+- **Entry Point**: Handles command-line arguments and application initialization
+- **SPA Routing**: Serves static HTML file for all non-API routes
+- **Device Discovery**: Automatic discovery of SoundTouch devices using unified discovery service
+- **JSON API Server**: Configures API routes and serves the SPA
+- **Context Management**: Proper context handling for timeouts and cancellation
+
+#### 2. HTTP Handlers (`handlers/handlers.go`)
+- **WebApp Structure**: Central application state management
+- **JSON API Endpoints**: RESTful API returning only JSON responses
+- **Device Control**: Device control with proper validation and error handling
+- **Modular Design**: Separated control actions into focused functions
+
+#### 3. WebSocket Support (`handlers/websocket.go`)
+- **Real-time Updates**: Live device status streaming to web clients
+- **Device WebSocket Connections**: Maintains persistent connections to SoundTouch devices
+- **Event Handling**: Processes nowPlaying, volume, and connection state updates
+- **Status Synchronization**: Keeps device status current across all connected clients
+
+#### 4. Type Definitions (`webtypes/types.go`)
+- **Device Management**: Structures for device connections and status
+- **API Responses**: Standardized JSON response format
+- **WebSocket Messages**: Real-time message types
+- **Template Data**: HTML template data structures
+
+### Key Features Implemented
+
+#### Device Discovery & Management
+- **Auto-discovery**: Finds SoundTouch devices on local network using mDNS/UPnP
+- **Multi-device Support**: Manages multiple devices simultaneously
+- **Connection Tracking**: Monitors device availability and connection status
+- **Device Information**: Displays device details (name, type, IP address)
+
+#### Real-time Control Interface
+- **Now Playing**: Live track information with artwork display
+- **Playback Controls**: Play/pause/stop/next/previous with visual feedback
+- **Volume Control**: Real-time volume slider with mute functionality
+- **Bass Adjustment**: Bass level control for supported devices
+- **Preset Management**: Quick access to saved presets (1-6)
+- **Source Selection**: Input switching (Spotify, TuneIn, Bluetooth, AUX, etc.)
+
+#### Web Interface
+- **Single-Page Application**: Self-contained HTML file with embedded CSS and JavaScript
+- **Responsive Design**: Bootstrap 5-based UI optimized for desktop and mobile
+- **Client-Side Routing**: JavaScript handles page navigation without page reloads
+- **Dynamic Rendering**: All HTML generated client-side from JSON data
+- **Real-time Updates**: WebSocket-powered live status updates
+- **Performance Optimized**: Fast loading and no template rendering delays
+
+#### API Endpoints
+```
+GET  /                          # SPA - serves static/index.html

+The main page shows all discovered devices with their current status, now-playing information, and quick controls.
+
+### Detailed Device Control
+Individual device pages provide full control over:
+- Detailed now-playing information with artwork
+- Comprehensive audio controls (volume, bass)
+- Full preset and source selection
+- Real-time status updates
+
+## Installation
+
+### Prerequisites
+- Go 1.21 or later
+- Access to SoundTouch devices on the same network
+- Modern web browser with WebSocket support
+
+### Building
+```bash
+# From project root
+make build
+
+# Or manually
+cd cmd/soundtouch-web
+go build -o soundtouch-web
+```
+
+### Running
+```bash
+# Run with default settings (port 8080)
+./soundtouch-web
+
+# Specify custom port
+./soundtouch-web -port 8888
+
+# Connect to specific device
+./soundtouch-web -host 192.0.2.100
+```
+

+```
+-port string    Web server port (default "8080")
+-host string    Specific SoundTouch device host (optional, enables single-device mode)
+-help          Show help information
+```
+
+## Usage
+
+### Accessing the Interface
+1. Start the application
+2. Open your web browser and navigate to `http://localhost:8080`
+3. Click "Discover Devices" to find SoundTouch devices on your network
+4. Click on any device for detailed control, or use quick controls from the main page
+
+### Device Discovery
+The application automatically discovers SoundTouch devices using:
+- **mDNS discovery** for local network devices
+- **UPnP/SSDP discovery** as fallback
+- **Manual device addition** via IP address
+
+### Real-time Updates
+The interface maintains WebSocket connections to each device for instant updates of:
+- Now playing information and artwork
+- Volume and audio settings changes
+- Playback status (play/pause/stop)
+- Connection status and device health
+
+### Responsive Design
+- **Desktop**: Full-featured interface with side-by-side panels
+- **Tablet**: Optimized layout with touch-friendly controls
+- **Mobile**: Stacked interface with gesture support
+
+## API Endpoints
+
+The web UI exposes a REST API for programmatic control:
+
+### Device Management
+```
+GET  /api/devices           # List all discovered devices
+GET  /api/device/{id}       # Get specific device info
+POST /api/discover          # Trigger device discovery
+```
+
+### Device Control
+```
+GET  /api/control/{id}/play        # Start playback
+GET  /api/control/{id}/pause       # Pause playback
+GET  /api/control/{id}/stop        # Stop playback
+GET  /api/control/{id}/next        # Next track
+GET  /api/control/{id}/previous    # Previous track
+POST /api/control/{id}/volume      # Set volume (body: {"level": 50})
+GET  /api/control/{id}/mute        # Mute audio
+GET  /api/control/{id}/unmute      # Unmute audio
+POST /api/control/{id}/bass        # Set bass (body: {"level": 0})
+GET  /api/control/{id}/preset?id=1 # Select preset
+GET  /api/control/{id}/source?name=SPOTIFY # Select source
+```
+
+### WebSocket Events
+Connect to `/ws` for real-time updates:
+```javascript
+const ws = new WebSocket('ws://localhost:8080/ws');
+ws.onmessage = function(event) {
+    const data = JSON.parse(event.data);
+    // Handle device updates, status changes, etc.
+};
+```
+
+## Architecture
+
+### Single-Page Application Architecture
+- **JSON API Backend**: Go server providing RESTful endpoints
+- **Client-Side Rendering**: JavaScript handles all UI rendering
+- **WebSocket Real-time**: Bi-directional real-time communication
+- **No Template Dependencies**: Eliminates server-side template issues
+
+### Backend Components
+- **Discovery Service**: Finds and manages SoundTouch devices
+- **WebSocket Manager**: Maintains real-time connections to devices
+- **JSON API Server**: RESTful interface returning only JSON
+- **Device Manager**: Tracks device state and health
+
+### Frontend Components
+- **Bootstrap 5**: Modern responsive UI framework
+- **Vanilla JavaScript**: No framework dependencies, fast loading
+- **WebSocket Client**: Real-time bidirectional communication
+- **Dynamic Rendering**: Client-side HTML generation from JSON
+
+### Communication Flow
+1. **SPA Loading**: Single HTML file with embedded CSS and JavaScript
+2. **JSON API**: Device discovery and control via REST endpoints
+3. **WebSocket (Device)**: Real-time status updates from SoundTouch devices
+4. **WebSocket (Browser)**: Real-time UI updates to web clients
+5. **Client Rendering**: JavaScript dynamically creates all UI elements
+
+## Development

+```
+
+### Adding New Features
+1. **API Endpoints**: Add new JSON routes in `setupRoutes()` and `handlers.go`
+2. **WebSocket Events**: Extend event handlers in WebSocket client
+3. **UI Components**: Add JavaScript rendering functions in `static/index.html`
+4. **Device Controls**: Implement new control commands and update client-side handlers
+
+### Testing
+```bash
+# Unit tests
+go test ./...
+
+# Manual testing with multiple devices
+./soundtouch-web -port 8080
+
+# API testing
+curl http://localhost:8080/api/devices
+```
+
+## WebSocket Protocol Analysis
+
+This UI is based on extensive analysis of captured SoundTouch WebSocket interactions, including:
+
+### Message Types Implemented
+- **SoundTouchSdkInfo**: Initial handshake and version info
+- **nowPlayingUpdated**: Real-time track information
+- **volumeUpdated**: Audio level changes
+- **recentsUpdated**: Recently played items
+- **userActivityUpdate**: User interaction notifications
+
+### Request/Response Patterns
+- **Device Information**: System details and capabilities
+- **Audio Controls**: Volume, bass, mute controls
+- **Playback Control**: Play/pause/stop/skip commands
+- **Source Selection**: Input switching (Spotify, TuneIn, etc.)
+- **Preset Management**: Saved station/playlist access
+
+### Gabbo Protocol Features
+- **Persistent Connections**: Maintains long-lived WebSocket connections
+- **Request Correlation**: Uses request IDs for response matching
+- **Real-time Events**: Instant updates for all device state changes
+- **Bi-directional Control**: Both status monitoring and device control
+
+## Browser Compatibility
+
+### Supported Browsers
+- **Chrome 80+** (recommended)
+- **Firefox 75+**
+- **Safari 13+**
+- **Edge 80+**
+
+### Required Features
+- WebSocket support
+- CSS Grid and Flexbox
+- ES6 JavaScript features
+- Responsive CSS media queries
+
+## Security Considerations
+
+- **Local Network Only**: Designed for local network device control
+- **No Authentication**: Assumes trusted local network environment
+- **CORS Policy**: Restricted to same-origin requests
+- **WebSocket Security**: Uses same-origin WebSocket connections
+
+## Troubleshooting
+
+### Common Issues
+
+**Devices Not Found**
+- Ensure devices are on the same network
+- Check firewall settings (ports 8090, 8080)
+- Click "Discover Devices" button to trigger discovery
+
+**WebSocket Connection Failed**
+- Verify device supports WebSocket connections
+- Check browser console for connection errors
+- Refresh the page to reconnect WebSocket
+
+**Control Commands Not Working**
+- Check device is powered on and connected
+- Verify device is not in exclusive mode (e.g., Spotify Connect active)
+- Look for error notifications in the UI
+
+**Page Shows Template Errors**
+- This has been fixed in the SPA implementation
+- Ensure you're accessing the correct URL (localhost:8080)
+- Clear browser cache if you see old template-based content
+
+### Debug Mode
+Add verbose logging by setting environment variable:
+```bash
+export DEBUG=true
+./soundtouch-web
+```
+
+## Contributing
+
+This web UI is part of the larger SoundTouch Go library project. See the main project README for contribution guidelines.
+
+### Architecture Benefits
+The new SPA approach provides:
+- **Better Performance**: No server-side template rendering
+- **Easier Development**: Clear separation of frontend/backend
+- **Mobile Ready**: Same JSON API can power mobile apps
+- **Scalable**: Single-page app architecture
+
+### Feature Requests
+Based on WebSocket interaction analysis, potential future features:
+- Zone/multi-room management
+- Clock display control
+- Software update management
+- Advanced preset programming
+- Progressive Web App (PWA) features
+

+# Device-Local Install: Four User Journeys
+
+A user-journey-shaped view of where AfterTouch sits today and where it could go. The same speaker, the same constraints, but four different audiences with non-overlapping needs:
+
+1. **Initial setup / install** — getting AfterTouch onto a fresh or freshly-orphaned speaker.
+2. **Less-technical admin** — migration, maintenance, and recovery without a terminal.
+3. **Daily usage** — playing music, switching presets, on the couch or on the phone.
+4. **Automation** — driving the speaker from scripts, home automation, schedules.
+
+Each journey is served by a different surface (CLI, web UI, GUI app, REST). Some surfaces serve more than one journey; some journeys are served badly today. This doc is informational; nothing here is a roadmap commitment.
+
+Cross-cutting reference material — lessons from `GameTec-live/soundtouch-tiny`, plus a per-surface capability map — lives in the appendix.
+
+---
+
+## Journey 1: Initial setup / install
+
+**Who.** Someone with a Bose speaker whose cloud just died. Could be technical (knows what SSH is) or not (knows what a USB stick is). Wants the speaker to play Internet Radio again with minimum fuss.
+
+**Goal.** Get an AfterTouch instance reachable from the speaker, whether that instance lives on a separate host or on the speaker itself.
+
+**Surfaces.** Shell (today), GUI installer (planned), pre-flashed stick (commercial offering, hypothetical).
+
+### The three install patterns
+
+#### Pattern A — External host
+
+A separate machine (Raspberry Pi, NAS, always-on laptop) runs `soundtouch-service`. Speakers point at it via DNS rewrite at the router. No code on the speaker, no firmware risk.
+
+- **Pros:** zero invasiveness, easy update (single host), unified for many speakers, no per-speaker storage limit.
+- **Cons:** requires an always-on host on the LAN, DNS rewrite at router scope, single point of failure.
+
+#### Pattern B — SSH-curl on-device (current `scripts/on-device-install/`)
+
+User SSHes in once, pipes the installer. Installs to `/mnt/nv/aftertouch`, symlinks `/opt/aftertouch`, registers `/etc/init.d/aftertouch` via `update-rc.d`. Daemon serves `:8000` on the speaker's own LAN address.
+
+- **Pros:** no separate host, per-speaker isolation, survives router replacement.
+- **Cons:** SSH required for install and updates, ~12 MB binary stresses tiny rootfs partitions, no in-process restart on crash, some firmware images bind only loopback (issue #196).
+
+#### Pattern C — Stick-driven on-device (*not* implemented here)
+
+USB stick holds binary + bootstrap scripts. First install needs SSH (placing `/mnt/nv/rc.local`). After that, the NAND `rc.local` auto-syncs from any stick inserted with newer files. Stick can also carry one-shot configs (`wlan.conf`, `region.conf`, `name.conf`) consumed and wiped during boot.
+
+- **Pros:** post-bootstrap updates need no SSH, stick wipe behavior keeps credentials short-lived, watchdog inside the bootstrap script restarts the agent on crash without a reboot.
+- **Cons:** first install still needs SSH; FAT32 stick on the speaker is unreliable for writes; user has to keep a stick around.
+
+### The technical underpinning: `/mnt/nv/rc.local`
+
+Both pattern C and any "shepherd-less" install on stock firmware depend on a single line in the stock init scripts:
+
+```
+# /etc/init.d/shelby_local, start case
+[ -x /mnt/nv/rc.local ] && /mnt/nv/rc.local
+```
+
+`shelby_local` is a stock Bose SysV script. Its `start` case fires at every boot from an `S`-symlink in `rcS.d/` (the misleading `K99shelby_local` symlink in `rc1.d/` is the *shutdown* path — same script, different case). `/mnt/nv` is the persistent read-write NAND partition; `rc.local` is intentionally exposed as an extension point. By the time it runs, rootfs is mounted read-only, `/mnt/nv` is read-write, network is configured, and `/media/sda1` is *typically* mounted by udev if a USB stick is present — but the mount is asynchronous and races the hook (polling for up to 30 s is one way to handle this).
+
+**Stock firmware does not auto-copy anything from a USB stick into `/mnt/nv/rc.local`.** Inserting a stick alone is not enough. There is no udev rule, no autorun convention, no `shelby_usb` branch that handles this; `shelby_usb` only manages USB ethernet-gadget mode (`g_ether`) and the `microbswitch` helper on certain variants.
+
+Placement happens one of two ways:
+
+1. **Manual SSH bootstrap, once.** Shell access (via the `remote_services` stick trick) runs an installer that writes `/mnt/nv/rc.local`, makes it executable, and exits. After that single SSH session, the stick is no longer required to *trigger* anything — the NAND copy fires on every boot.
+2. **Self-update from a newer stick, after step 1.** Once `/mnt/nv/rc.local` exists *and contains the self-update logic*, inserting a stick with a newer `rc.local` (compared by mtime) lets the running NAND copy overwrite itself for the next boot. This gives the stick its "repair channel" property.
+
+**The very first placement requires SSH.** Any zero-SSH install would need either a different stock-firmware hook (we have not found one usable across SoundTouch variants) or a custom firmware image. The `remote_services` stick is the only stick-content convention the stock firmware honors out of the box, and all it does is enable `sshd`.
+
+### App-driven install (the missing middle)
+
+The SSH session does **not** have to be a human SSH session. `pkg/ssh` (`NewClient`, `Run`, `ReadFile`, `ReadDir`, `UploadContent`) is already used by `pkg/service/setup/` to drive migration probes; the same primitives can drive an installer. The user never sees a terminal.
+
+User-visible flow:
+
+1. User runs an admin app on their laptop or phone.
+2. App walks them through preparing a `remote_services` stick — or writes one for them, if it can reach the host's USB subsystem.
+3. User inserts the stick into the speaker and power-cycles it. Stock firmware's `sshd` starts.
+4. App discovers the speaker via mDNS, dials SSH, runs the installer steps that today live behind `curl ... \| sh`. No `ssh` invocation, no `rw &&`, no copy-pasted IP.
+5. App verifies `curl http://<box>:8000` from inside the speaker via SSH and surfaces a clear success / failure state.
+6. App optionally removes `remote_services` from the stick and reboots the speaker, closing the SSH backdoor automatically.
+
+Mapping each step to existing code:
+
+| Step                | Today's installer                                                       | App equivalent (`pkg/ssh`)                                                                                  |

+
+No new SSH plumbing required. The pieces already exist for the setup probes.
+
+### Storage budget
+
+The on-device patterns share one hard constraint: storage. ST20 stock rootfs has ~4 MB free (issue #268); even with `/mnt/nv` (~30 MB free) the budget is tight, and a second binary for safe OTA updates doubles it. This is the primary motivation for a slimmer `soundtouch-service-mini` build target — see the appendix.
+
+### Open decisions for this journey
+
+- Do we keep pattern B as the technical-user path while building a Gio admin app for the rest?
+- Do we add a pattern-C-style "register a stick-update hook in `/mnt/nv/rc.local`" option as an opt-in, so users who do want a repair stick get one?
+- Pre-flashed sticks shipped as a kit: in scope or out?
+
+---
+
+## Journey 2: Less-technical admin (migration + maintenance)
+
+**Who.** The person who already has AfterTouch installed somewhere and now needs to do something *after* install. They are comfortable opening apps and clicking buttons; they are not comfortable opening a terminal. The whole-household admin: parent, partner, roommate doing it for the household.
+
+**Goal.** Migrate a speaker to a new AfterTouch instance, update the agent, view what's going on, recover a stuck device, change WLAN credentials, reapply config after factory reset — all without SSH.
+
+**Surfaces.** GUI admin app (Gio, planned), `soundtouch-service` embedded web UI (today, technical-leaning), CLI (today, technical-only).
+
+### What "admin" covers in practice
+
+- **Migration of a new (or factory-reset) speaker** to an AfterTouch instance: rewrite the server URLs in `/mnt/nv/persistence.json`, restart the device, verify it talks to us.
+- **Agent update on an on-device install** (pattern B or C): push a new binary, restart, verify.
+- **Status and diagnostics**: is `aftertouch` running, is `:8000` listening, did the last preset save succeed, what does syslog say?
+- **Recovery**: speaker is stuck (won't respond to web UI, won't pair, lost WLAN). Today this almost always means SSH; with `pkg/ssh` behind a GUI, it can mean "click 'Diagnose' in the app."
+- **Bulk operations**: do all of the above across several speakers at once.
+- **Configuration drift**: WLAN password changed, region changed, speaker name changed, hosts file got rewritten — restore the AfterTouch overlay.
+
+### How the GUI admin app shape would serve this
+
+Same `pkg/ssh` primitives as Journey 1's installer, applied to post-install tasks. mDNS discovers all speakers on the LAN; the app fans operations out across them; SSH-driven actions stay hidden behind buttons. On a phone, the same app is the "speakers are unreachable, what now" diagnostic tool from another room.
+
+Where today's surfaces fall short for this user:
+
+- `soundtouch-service` web UI assumes the service is running and reachable. It cannot recover a broken installation or a stuck device.
+- CLI works but presumes terminal comfort.
+- The setup wizard in `soundtouch-service` handles initial migration well, but reapplying after factory reset is not first-class — see `docs/analysis/FACTORY-RESET-PROTOCOL.md`.
+
+### Open decisions for this journey
+
+- Does the admin app subsume the service web UI's admin tab, or do they coexist (admin app = onboarding + recovery; service web UI = ongoing operations once everything is healthy)?
+- WASM as a fallback surface: today's service web UI is browser-accessible from anywhere. Does a Gio admin app sacrifice that, or do we ship both?
+- Multi-household / multi-speaker: how much does the admin app need to know about distinguishing speakers vs distinguishing AfterTouch instances?
+
+---
+
+## Journey 3: Daily usage
+
+**Who.** Anyone in the household using the speaker. Children pressing a preset button. The user opening a phone to switch from kitchen to living room. Guests asked to "just put on some jazz." Zero awareness of AfterTouch as a thing; the speaker is the speaker.
+
+**Goal.** Music plays. Pressing preset 3 gives them what preset 3 should give them. Skipping a station, adjusting volume, browsing for a new station — all fast, no friction.
+
+**Surfaces.** Physical preset buttons (always there), `soundtouch-web` (today), mobile app (Journey 2 admin app's daily-use mode), WASM-served browser UI (planned), Bose app while it still functions, voice assistants where wired up.
+
+### What this layer needs to be good at
+
+- **Preset playback works first try, every time.** The reliability bar is "is the kitchen radio still working?" Anything that fails on cold boot or after a Wi-Fi outage breaks the user's trust in the whole system.
+- **Switching stations quickly**, including discovery of new ones (e.g. `radio-browser.info`-style search).
+- **Volume and play / pause from any device the user has in hand.** Phone in pocket, laptop on table, browser tab open — all should work.
+- **Multi-room awareness** if the household has more than one speaker: which speaker is playing what, can I send this to the bedroom.
+- **Looking good.** This is the surface that gets seen daily by non-technical users. Visual polish matters more here than anywhere else in the stack.
+
+### How surfaces map
+
+- `soundtouch-web`: primary daily UI for desktop browsers and (responsively) for tablets. This is already shipped.
+- Mobile app: daily-use mode of the same Gio app that handles admin. Capability split — admin features only show up when the user is in admin mode.
+- WASM: same Gio app, served from `soundtouch-service` to anyone on the LAN. The "I forgot which device my login is on, just open a browser" fallback.
+- Physical preset buttons: handled at the agent level (the Bose firmware fires them; AfterTouch or the on-device agent reacts).
+
+### Open decisions for this journey
+
+- Do we keep `soundtouch-web` as a separate codebase (HTML/JS), or does it become a Gio WASM build sharing code with the admin app?
+- Mobile app store distribution: TestFlight for iOS (gated, slow), Play Store for Android (faster, AAB only), F-Droid as an open-source-friendly side path.
+- Multi-user state: presets per-user vs per-household. Out of scope here, but the daily surface is where it gets felt.
+
+---
+
+## Journey 4: Automation
+
+**Who.** The same household, but acting through code: a Home Assistant config, a NodeRED flow, a cron job, a shell script, a webhook from a smart doorbell. The user is not present at the speaker; they want music to start when something else happens.
+
+**Goal.** Headless, scriptable control. "Play preset 2 at 7:00 every weekday." "When the kids' bedtime alarm fires, fade volume to zero." "If I get home and the speaker is on, switch to my dinner playlist."
+
+**Surfaces.** `soundtouch-cli` (today), REST endpoints on `soundtouch-service` (today), MQTT bridge / webhook outputs (hypothetical), Home Assistant integration (community).
+
+### What this layer needs to be good at
+
+- **Stable, versioned API surface.** Scripts and home automation flows live for years; breaking changes are expensive for users.
+- **CLI that works in pipelines.** Exit codes, machine-readable output (JSON), stable flag names. The reverse of the daily UI: zero polish, full predictability.
+- **Discoverability of capabilities.** Users need to find out what's possible (`soundtouch-cli help`, openapi spec on the service, examples in the docs).
+- **Idempotency.** Calling "set volume to 40" twice should not result in volume 80. Calling "switch to preset 3" when already on preset 3 should be a no-op.
+
+### How surfaces map
+
+- `soundtouch-cli`: the canonical surface for scripted control. Already covers most of the API.
+- `soundtouch-service` REST endpoints: same surface, network-accessible. Used by `soundtouch-web` and by third-party automation.
+- Home Assistant: external integration; track but do not own.
+- Webhooks / MQTT: not present today; would let speakers participate in event-driven flows. Out of scope for a first pass; worth a separate design doc when demand surfaces.
+
+### Open decisions for this journey
+
+- Stability commitments for the CLI and REST API: do we adopt semver for the public surface separately from the service version?
+- Authentication for the REST surface when exposed beyond loopback: needed before any internet exposure is sane.
+- OpenAPI / typed-client output for the service: nice-to-have for integration developers.

+| Physical preset buttons            | no                  | no                | primary           | no                     |
+| Home Assistant / webhooks (future) | no                  | no                | no                | primary                |
+
+The diagonal isn't full because some journeys lack a polished surface today (Journey 1 mostly works but is shell-only; Journey 2 has gaps for recovery scenarios). The journey frame is what tells us *which* gaps to fill first.
+
+## Appendix: per-surface capability constraints
+
+The Gio admin app, if built, can target Windows / macOS / Linux / iOS / Android / WASM from one codebase. Each target has hard constraints:
+
+- **WASM (browser).** Post-install REST control, device list and status, preset editing, station search. No mDNS (browsers cannot do raw multicast — fall back to manual IP entry or a backend bridge); no raw TCP, so no SSH and no install; no block-device access, so no stick writing. This is the "I just want to use my speakers" surface, equivalent to today's `soundtouch-web`.
+- **Mobile iOS.** Everything WASM does, plus Bonjour-based mDNS, plus full SSH client (so app-driven install and recovery work). No FAT32 stick writing — iOS has no filesystem-level block device access for third-party apps. Best paired with a pre-flashed stick or a friend's desktop install for the bootstrap.
+- **Mobile Android.** Same as iOS, plus FAT32 stick writing *if* the user grants USB-OTG host permission. UX caveat: most users will not know what USB host mode is.
+- **Desktop (Gio).** Full capability set. mDNS, SSH-driven install, FAT32 stick writing via standard block-device APIs, post-install control, recovery. The primary onboarding surface.
+
+The pattern to follow is to write code so each capability degrades automatically based on what the runtime actually offers, rather than gating with build tags.
+
+## Appendix: lessons from adjacent projects
+
+### soundtouch-tiny (GameTec-live)
+
+Minimal on-device cloud replacement: Internet Radio + TuneIn proxy + optional presets. Go stdlib only, small binary. Inspired by AfterTouch but trimmed. The author offered collaboration in PR #292.
+
+This is the gap a **`soundtouch-service-mini` build target** would fill. The full `soundtouch-service` is justified for the external-host pattern (Pattern A) where space is not pressed; on-device (patterns B and C) the calculus is different — many users only need Internet Radio because that's the surface most affected by the cloud shutdown.
+
+A mini build target in this repo would look like:
+
+- same codebase, different `cmd/` entry point,
+- compiled with only the packages needed for Internet Radio + TuneIn shim + presets,
+- no Spotify, no parity tests, no setup wizard, no Bose-protocol-level proxy,
+- target size: under 4 MB so it fits the rootfs without `/mnt/nv` gymnastics, leaving room for a second binary for safe updates.
+
+Open questions before committing:
+
+1. Collaborate upstream with soundtouch-tiny, or build our own mini that shares code with the full service?
+2. Where to draw the feature line — "Internet Radio only" is clear; "Spotify too" would already blow the budget on ST20.
+3. Mini ships via Pattern B (SSH-curl) or Pattern C (stick)?
+4. Full service and mini service coexisting on the same LAN — mDNS service name, port choice, web UI port.
+
+### Wails vs Gio
+
+Both are Go. Different tradeoffs:
+
+- **Wails v2**: bundles a WebView per OS, frontend is HTML/CSS/JS. Faster to a working UI if the team is comfortable with HTML. Targets Windows / macOS / Linux. No mobile, no WASM.
+- **Gio**: immediate-mode pure-Go UI. Smaller binaries, no WebView dependency. Targets Windows / macOS / Linux / iOS / Android / WASM. Steeper UI learning curve, mitigated by `gio-mw`.
+
+The deciding factor is **mobile + WASM** (Journey 2 and Journey 3), not desktop alone. If "use a phone to set up a speaker" or "open the admin tool from any browser" is on the roadmap, Wails does not get us there.
+
+## Appendix: documentation gap to close
+
+Separate user-facing material to produce when we are ready (not in this comparison doc):
+
+- **The `/mnt/nv/rc.local` hook** explained in user terms: what it does, when it fires, when *not* to use it, how to remove it cleanly. Bridges Journey 1 and Journey 2.
+- **Hooks we already maintain** at OS level: resolv.conf stability, `/etc/hosts` overlay, anything in `pkg/service/setup/` that touches device state. Reference, not narrative. Journey 2 troubleshooting.
+- **Storage budget per model**: rootfs free, `/mnt/nv` free, where the binary lands, which path applies to which ST model. Journey 1 sizing.
+- **Decision matrix**: external host vs on-device vs mini, plus "do I need Spotify? do I need migration? do I want one host or per-speaker isolation?" Journey 1 entry point.
+- **Stick file conventions**: what the `remote_services` stick does today, what we *might* add (presets / wlan / region) if we build a stick-driven path, and how that interacts with FAT credentials residency. Journey 1.
+- **Automation cookbook**: example Home Assistant config, example shell scripts, common pitfalls. Journey 4.

+# Bose SoundTouch Device Setup Flow
+
+This document details the multi-step process required to fully set up a Bose SoundTouch device, as derived from the Stockholm firmware (`setup/js/`) analysis.
+
+A complete setup flow involves a sequence of local (WebSocket) and cloud (HTTP) actions that move the device from a factory-reset state to a fully registered, functional system.
+
+## 1. Local Coordination Stage (WebSocket)
+
+Before a device can be controlled, it must be configured on the local network and named. These actions occur via a WebSocket connection to the device on port 8080.
+
+### 1.1 Language Configuration (Optional)
+If the device is in a factory-reset state, the UI typically ensures the device language matches the user's choice.
+- **WebSocket Action**: `set_language`
+- **Internal Logic**: `SetupWizard.js` handles this via `set_device_language`.
+
+### 1.2 Network Configuration (WiFi)
+Configures the device to connect to a specific wireless access point.
+- **File Reference**: `setup/js/workflow_wifi_setup.js`
+- **Logic**: Triggers a site survey, then sends SSID and credentials.
+- **WebSocket Command**: `set_WIFI_OLED` or similar internal method calls to configure the network profile.
+
+### 1.3 Device Naming (Rename Step)
+Assigns a user-friendly name (e.g., "Living Room") to the device.
+- **File Reference**: `setup/js/workflow_rename.js`
+- **WebSocket Action**: `name`
+- **XML Payload**:
+    ```xml
+    <name>Living Room</name>
+    ```
+- **Implementation**: The `RenameDevices.do_rename_devices()` function sends this to the device. The device then updates its local name and mDNS/SSDP broadcasts.
+
+## 2. Cloud Interaction Stage (HTTP)
+
+The device needs to be linked to a Bose "Marge" account to enable cloud-based features and music services.
+
+### 2.1 Account Creation (Registration)
+If a user doesn't have an account, the setup client creates one.
+- **File Reference**: `setup/js/workflow_marge.js`
+- **Cloud Endpoint**: `POST https://streaming.bose.com/streaming/account`
+- **Payload**: XML containing name, email, password, and country.
+- **Content-Type**: `application/vnd.bose.customer-v1.0+xml`
+
+### 2.2 Cloud Authentication (Login)
+The setup client must obtain a valid `accountId` and `userAuthToken` to pair the device.
+- **File Reference**: `setup/js/workflow_marge.js`
+- **Cloud Endpoint**: `POST https://streaming.bose.com/streaming/account/login`
+- **Payload**: XML containing username and password.
+- **Content-Type**: `application/vnd.bose.streaming-v1.2+xml`
+- **Result**: Returns a session token in the `Credentials` response header and the user's `account ID` in the XML body.
+
+## 3. Registration Bridge (WebSocket to Cloud)
+
+This is the final "pairing" step where the client tells the device which account it belongs to.
+
+### 3.1 Device Registration (The "Pair" Step)
+The client sends the user's credentials to the device, which then registers itself with the cloud.
+- **File Reference**: `setup/js/workflow_add_devices.js`
+- **WebSocket Action**: `setMargeAccount`
+- **XML Payload**:
+    ```xml
+    <PairDeviceWithAccount>
+        <accountId>12345</accountId>
+        <userAuthToken>jGwE... (truncated)</userAuthToken>
+    </PairDeviceWithAccount>
+    ```
+- **Device Reaction**: Upon receiving this, the device makes its own outbound HTTP POST to the Marge service:
+    `POST https://streaming.bose.com/{accountId}/devices`
+
+## 4. Finalization
+
+Once the registration is complete, the setup application (Stockholm) performs final cleanup. It's important to distinguish between **App State** (the Stockholm UI's persistent settings) and **Device State** (the physical speaker's configuration).
+
+### 4.1 Exiting Setup Mode (App Settings)
+The Stockholm app communicates with its "native container" (the WebView bridge on iOS/Android/Windows/macOS) using a `setData` command in **JSON format**. This is an internal message to the application's persistent storage, **not a network command sent to the physical speaker**.
+
+This command tells the Stockholm app which page to load on startup, effectively marking the setup as complete in the UI.
+
+- **Internal Command**: `setData`
+- **Parameter**: `startupPage`
+- **Normal Value**: `index.html` (Normal mode)
+- **Setup Value**: `setup/index.html` (Setup mode)
+
+**JSON Payload (Internal to Stockholm App)**:
+```json
+{
+    "method": "setData",
+    "params": {
+        "name": "startupPage",
+        "value": "index.html"
+    }
+}
+```
+
+**Other Common Internal Parameters**:
+- `changeStartupPage`: Set to `false` after a successful setup or update.
+- `tipsEnabled`: Set to `false` to suppress the "Getting Started" tutorials.
+- `promptUpdate`: Set to `true` if a firmware update was deferred during setup.
+
+### 4.2 Device Finalization
+The physical speaker considers the setup "done" once it successfully processes the `<PairDeviceWithAccount>` XML message and completes its own handshake with the Marge cloud. There is no specific "Finalize" XML command sent to the speaker; the successful registration is the signal.
+
+The `SetupWizard.js` calls `single_device_setup_done()` to trigger the internal `setData` updates described above. If these are not saved in the app's local storage, the Stockholm UI may return to the setup flow on next launch, even if the speaker is already paired.
+
+---
+
+## Summary of Scriptable Requirements
+
+To automate a device setup using a custom tool (like `soundtouch-cli`), you must perform the following:
+1.  **Configure WiFi**: (Assumed if device is reachable over IP).
+2.  **Set Name**: Send the `<name>` WebSocket message (XML) to update the device identity.
+3.  **Obtain Token**: Authenticate against the cloud service (Marge) via HTTP.
+4.  **Pair Device**: Send the `<PairDeviceWithAccount>` WebSocket message (XML) with the account ID and token.
+
+**Note**: The JSON `setData` commands are only necessary if you are building/controlling a version of the Stockholm UI itself. They are not required to configure the physical hardware.

+# Encrypted Diagnostic Export
+
+AfterTouch can produce an encrypted diagnostic report that users can download and
+send to the project maintainer without exposing sensitive data to third parties.
+The report is encrypted with an SSH public key using
+[`age`](https://github.com/FiloSottile/age); only the holder of the matching
+private key can read it.
+
+---
+
+## What the report contains
+
+The encrypted `.age` file decrypts to a `.tar.gz` archive with:
+
+- `diagnostic.json` — structured summary:
+  - Service version and build info
+  - Full health-check results (same data as the Health tab)
+  - Per-device state: sources (IDs, names, SourceKeyTypes), presets (slot, name,
+    Source, SourceID, location), device product code, firmware version, IP, name
+- `datastore/accounts/{id}/devices/{id}/*.xml` — raw XML files verbatim from
+  the sender's datastore (`Presets.xml`, `Sources.xml`, `Recents.xml`, …)
+
+Having both the structured JSON and the raw XML lets you compare what the
+service serves via HTTP against what is actually stored on disk.
+
+**What is excluded from the JSON:** authentication tokens, credentials, OAuth
+secrets, Spotify refresh tokens. The raw XML files are included as-is.
+
+---
+
+## Maintainer setup (one-time)
+
+> This section is for the project maintainer only.
+> Users never need to touch keys.
+
+### 1. Generate the key pair
+
+```bash
+bash scripts/setup-diagnostic-key.sh
+```
+
+This creates:
+- `keys/private/diagnostic` — SSH ed25519 private key (**gitignored**, never commit)
+- `keys/private/diagnostic.pub` — copy for reference (**gitignored**)
+- `keys/public/diagnostic.pub` — public key committed to the repo
+
+### 2. Add the public key to GitHub
+
+Go to <https://github.com/settings/ssh/new> and paste the contents of
+`keys/public/diagnostic.pub`. This makes the key visible at
+<https://github.com/gesellix.keys> so users can independently verify that the
+key embedded in the binary matches a key actually controlled by the maintainer.
+
+### 3. Embed the public key in the binary
+
+Open `pkg/service/export/encrypt.go` and update the `DiagnosticPublicKey`
+constant to match the new public key:
+
+```go
+const DiagnosticPublicKey = "ssh-ed25519 AAAA... aftertouch-diagnostic@gesellix"
+```
+
+### 4. Commit
+
+```bash
+git add keys/public/diagnostic.pub pkg/service/export/encrypt.go
+git commit -m "keys: add diagnostic SSH public key"
+```
+
+`keys/private/` is `.gitignore`d — the private key will not be committed.
+
+### 5. Back up the private key
+
+The private key is **not** stored in git. Keep a copy in a secure location
+(password manager, encrypted USB drive, etc.). If it is lost, a new key pair
+must be generated and the constant in `encrypt.go` updated.
+
+---
+
+## Verifying the embedded key (users)
+
+Users who want to confirm that the key embedded in their running binary matches
+the maintainer's GitHub SSH keys can run:
+
+```bash
+# Compare the raw key text — both should show the same line:
+curl -s https://github.com/gesellix.keys
+cat keys/public/diagnostic.pub
+```
+
+The key should appear verbatim in both outputs.
+
+---
+
+## Decrypting a received report (maintainer)
+
+When a user sends you an `aftertouch-diagnostic-*.age` file, use the helper
+script (no extra tools needed — only Go and the private key). Run from the
+repository root directory:
+
+```bash
+# Decrypt and extract in one step:
+go run scripts/decrypt-diagnostic.go aftertouch-diagnostic-<timestamp>.age | tar xz
+
+# Or decrypt to a .tar.gz first, then inspect:
+go run scripts/decrypt-diagnostic.go aftertouch-diagnostic-<timestamp>.age > report.tar.gz
+tar xzf report.tar.gz
+# → diagnostic.json
+# → datastore/accounts/{id}/devices/{id}/Presets.xml  (and Sources.xml, Recents.xml, …)
+```
+
+The script uses only the `filippo.io/age` Go module — no separate `age` CLI
+installation required.
+
+---
+
+## User workflow
+
+1. Open the AfterTouch admin UI and go to the **Health** tab.
+2. Click **Download diagnostic report**.
+3. The browser downloads `aftertouch-diagnostic-<timestamp>.age`.
+4. Attach the file to the GitHub issue or send it via a direct channel.
+
+The file is opaque binary — the user cannot read it. All they see is that the
+report was generated and downloaded.
+
+---
+
+## Key rotation
+
+If the private key is compromised or lost:
+
+1. Run `scripts/setup-diagnostic-key.sh` (delete the old `keys/private/diagnostic` first).
+2. Add the new public key to GitHub and remove the old one.
+3. Update `DiagnosticPublicKey` in `encrypt.go`.
+4. Commit and tag a new release.
+
+Old reports encrypted with the previous key cannot be decrypted with the new key.

+# Technical Proposal: External Service Provider Abstraction
+
+This document outlines a strategy to refactor the SoundTouch Service's content handling into a modular provider-based system.
+
+## 1. Problem Statement
+Currently, content handling for BMX (Bose Media Exchange) services like TuneIn or RadioBrowser is deeply intertwined with the HTTP handlers and XML models. Adding a new content provider (e.g., Local Media, Podcast RSS) requires modifying several files and duplicating boilerplate code for HTTP requests and error handling.
+
+## 2. Proposed Architecture
+
+### 2.1 The Provider Interface
+We define a generic `ContentProvider` interface that abstracts away the source-specific logic (API calls, data parsing).
+
+```go
+package provider
+
+import "github.com/gesellix/bose-soundtouch/pkg/models"
+
+type ContentProvider interface {
+    // ID returns the unique identifier for this provider (e.g. "RADIO_BROWSER")
+    ID() string
+
+    // Resolve returns playback details for a given content identifier
+    Resolve(id string) (*models.BmxPlaybackResponse, error)
+
+    // Search allows finding content within this provider
+    Search(query string) ([]models.ContentItem, error)
+}
+```
+
+### 2.2 Provider Registry
+A central registry in `soundtouch-service` manages the lifecycle and selection of providers.
+
+```go
+type Registry struct {
+    providers map[string]ContentProvider
+}
+
+func (r *Registry) Register(p ContentProvider) { ... }
+func (r *Registry) Get(id string) ContentProvider { ... }
+```
+
+## 3. Implementation Plan
+
+### 3.1 Phase 1: Modularize RadioBrowser
+1.  **Extract Logic**: Move current RadioBrowser logic from `bmx.go` into a new package `pkg/service/providers/radiobrowser`.
+2.  **Add Failover**: Implement the **API Failover** logic inspired by OpenCloudTouch.
+    -   Maintain a list of active RadioBrowser mirrors (e.g., `de1.api.radio-browser.info`, `nl1.api.radio-browser.info`).
+    -   Implement a round-robin or health-based selection strategy.
+3.  **Implements Interface**: Ensure the new package satisfies the `ContentProvider` interface.
+
+### 3.2 Phase 2: Refactor BMX Handlers
+-   Update `HandleTuneInPlayback` and `HandleOrionPlayback` to use the registry.
+-   The handlers will look up the provider based on the request context or URL parameters and delegate the resolution.
+
+### 3.3 Phase 3: Dynamic Service Advertising
+-   Modify `HandleBMXRegistry` to dynamically generate the `bmx_services.json` content based on the currently registered and enabled providers.
+
+## 4. Benefits
+-   **Resilience**: Centralized error handling and failover strategies for all external APIs.
+-   **Extensibility**: New services can be added by simply implementing the interface and registering them at startup.
+-   **Testability**: Providers can be unit-tested in isolation without mocking the entire HTTP server stack.
+-   **Unified UI**: A future Web UI can query the registry to show available content sources and their statuses.
+
+## 5. Next Steps
+1.  Refine the `ContentProvider` interface to include metadata (icons, user-friendly names).
+2.  Create a prototype for the `radiobrowser` provider with failover support.

+#### ✅ Completed Improvements (Marge Service)
+*   **Mapped Preset `buttonNumber`**: Correctly mapped the internal `ServicePreset.ID` or `ButtonNumber` to the `buttonNumber` XML attribute in the `/full` response and ensured it is persisted in the local datastore.
+*   **High-Fidelity Device Metadata**: Improved the datastore to correctly extract, persist, and report detailed device `<components>` (e.g., `LIGHTSWITCH`, `SMSC`) and their firmware versions from upstream responses.
+*   **Standardized Preferred Language**: Updated the default `preferredLanguage` to `de` in the `/full` response and added synchronization to persist it from upstream responses.
+*   **Persisted Provider Settings**: Added support for persisting and echoing back `providerSettings` (e.g., `STREAMING_QUALITY`, `ELIGIBLE_FOR_TRIAL`) from the `/full` response.
+*   **Populated `contentItemType`**: The `contentItemType` (e.g., `tracklisturl`) is now correctly synchronized from upstream, persisted in the local datastore, and returned in the `/full` response for both presets and recents.
+*   **Standardized Credential Types**: Adjusted the logic for Spotify to use the correct `token_version_3` type when a token is present in the `/full` response, improving parity with the upstream service. The service now respects existing `credential_type` values from `Sources.xml` (e.g., `token_version_3` for Spotify) while providing sensible defaults for new or incomplete sources.
+*   **Structured Sources (Sources.xml)**: Refactored `Sources.xml` to use an attribute-based structure (`sourceid`, `source`, `status`, `sourceAccount`, etc.) matching the real device's output. Removed redundant nested tags like `<sourcename>`, `<username>`, and `<name>`.
+*   **Nested Recents (Recents.xml)**: Implemented a nested `<contentItem>` structure within `<recent>` entries in `Recents.xml`, maintaining exact parity with the device's persistence format while supporting legacy flat formats for backward compatibility.
+*   **Inconsistent `serialNumber` Casing**: Fixed the casing mismatch in the `/full` response where the upstream uses camelCase `<serialNumber>` in the top-level `<device>` and lowercase `<serialnumber>` in the nested `<attachedProduct>`. Local responses now correctly mirror this inconsistency.
+*   **Attribute-level Parity**:
+    *   Ensured `sourceAccount=""` is preserved in XML even when empty, matching device behavior for sources like TUNEIN.
+    *   Fixed casing for attributes like `deviceID` and `utcTime` in `Recents.xml`.
+    *   Correctly mapped and persisted preset and recent `id` attributes during "Initial Data Sync".
+*   **Device Name Consistency**: Fixed an issue where the device `<name>` was empty in some local `/full` responses by ensuring it is correctly populated from the datastore and synchronized from upstream.
+*   **Improved XML Parity**: Empty `<name>` tags in the `/full` response are now self-closing (`<name/>`), matching upstream behavior.
+*   **Timestamp-based ID Generation**: Implemented a 9-digit ID schema (`YYMMDD` + 3-digit counter) for `recent` items, ensuring IDs are large, unique, and stay within the 32-bit integer range.
+*   **Automatic Source Learning**: The service now extracts and persists full metadata (credentials, provider IDs, and custom names) from incoming `POST /recent` requests. This improves parity for subsequent `GET /recents` calls.
+*   **Source Provider Mapping**: Synchronized local source provider IDs and timestamps with upstream data. The `RADIO_BROWSER` provider is included in the public `/streaming/sourceproviders` list to maintain internal functionality while acknowledging it as a parity gap.
+*   **Credential Preservation**: Improved `AddRecent` to correctly extract and echo back base64 tokens/credentials provided in the incoming request, improving source learning.
+*   **XML Formatting Parity**:
+    *   Added `standalone="yes"` to the XML declaration for all Marge responses, including `recent`, `presets`, `full account`, `software update`, and `sourceproviders`.
+    *   Enforced self-closing `<sourceSettings/>` tags for parity.
+    *   Standardized date formatting to UTC with milliseconds (`.000+00:00`).
+    *   Fixed casing for `/streaming/sourceproviders`: Root element is `<sourceProviders>`, but child elements are `<sourceprovider>` (all lowercase), matching upstream behavior.
+    *   Implemented structured XML marshaling with consistent 2-space indentation for recents and source providers.
+*   **Improved TuneIn Parity**: Fixed TuneIn source mapping to use ID `25` and ensuring `sourcename` is empty in responses, matching upstream behavior for station playback.
+*   **High-Fidelity Full Account Sync**: Refactored the `/streaming/account/{accountId}/full` response to match the upstream structure. This includes:
+    *   **Mapped Preset `buttonNumber`**: Correctly mapped the internal `ServicePreset.ID` to the `buttonNumber` XML attribute in the `/full` response.
+    *   **Structured XML Marshaling**: Replaced manual string concatenation with structured Go models and `xml.Marshal` for the entire response.
+    *   **Specific Response Models**: Introduced `FullResponseSource`, `FullResponsePreset`, and `FullResponseRecent` to accurately reflect the upstream structure where `<source>` is a child element, rather than a set of attributes.
+    *   **Correct Nesting**: Ensured that `<presets>` and `<recents>` correctly nest their associated `<source>` details, resolving previous data omissions.
+    *   **Device Identity**: Added `<serialNumber>` and `<updatedOn>` to both the top-level `<device>` and its `<attachedProduct>`, ensuring consistent device identification.
+    *   **Field-Level Parity**: Mapped missing fields like `<contentItemType>` and `<productlabel>` to match upstream expectations.
+    *   **Improved Source Matching**: Enhanced internal logic to correctly link presets and recents to their configured sources based on multiple identifiers (ID, Key, or Type).
+*   **Verified Parity Mismatch Fixes**: The reproduction test `TestParityMismatchReproduction_V2` confirms parity for identified mismatches in `POST /recent` and `GET /recents`, including credentials and source-specific metadata.
+*   **Unified Response Logic**: Refactored the code so that both `POST /recent` and `GET /recents` use the same formatting functions, guaranteeing consistency.
+*   **Maintainable XML Generation**: Reduced cyclomatic complexity and code duplication in `marge.go` by extracting focused helper functions for mapping internal data to response-specific XML models.
+
+---
+
+#### 🛠️ Open Issues and Next Steps
+
+Based on the latest `parity_mismatches` and the high-fidelity `/full` account response comparison (diff14), here are the recommended areas for further work:
+
+#### 1. BMX / TuneIn Playback Parity (Medium)
+Current mismatches in `/bmx/tunein/v1/playback/station/...` show differences in reporting URLs and missing links:
+*   **Mismatched Parameters**: Local reporting URLs use `listen_id=1234567890`, while upstream uses a different session-based ID.
+*   **Missing Links**: Some upstream responses include additional `_links` or metadata that are currently omitted in local responses.
+*   **Action**: Improve the `HandleTuneInPlayback` logic to better mirror the upstream response structure and parameter generation.
+
+#### 2. `/full` Account Response Data Gaps (Medium)
+While structural parity for the `/full` response is high, several value-level gaps remain as shown in `diff14`:
+*   **Timestamp Formats**: Upstream uses ISO-8601 with milliseconds (e.g., `2024-06-23T07:40:36.000+00:00`), whereas some local fields still use Unix epoch integers (e.g., `1234567890`).
+*   **Provider Settings**: The `providerSettings` block in the local response currently lacks crucial values like `keyName`, `providerId`, and `boseId` (appearing as empty tags).
+*   **Component Metadata**: Local component types are sometimes empty (`type=""`) compared to upstream values like `LIGHTSWITCH` or `SMSC`.
+*   **Source/Preset Identifiers**: Local IDs (e.g., `100004`) differ from upstream IDs (e.g., `1234567`), though this may be expected due to different account/device environments.
+*   **Action**: Update the mapping logic in `marge.go` and `setup.go` to ensure all fields in the `/full` response are correctly populated with high-fidelity values and standard ISO-8601 timestamps.
+
+#### 3. OAuth / Spotify Token Noise (Low/Medium)
+The `/oauth/device/.../token` endpoint frequently reports mismatches because tokens are naturally different between local and upstream.
+*   **The Issue**: This creates "noise" in your parity reports that isn't actually a bug.
+*   **Action**: Update the parity detection logic (or the handler) to selectively ignore the `access_token` field while still verifying that the rest of the JSON structure (expires_in, scope, token_type) matches.
+
+#### 4. Large IDs for Other Models (Medium)
+While we fixed IDs for `recents`, other models like `presets` or `sources` might still use small auto-incrementing integers.
+*   **Action**: Evaluate if other endpoints should also transition to the timestamp-based ID schema to further reduce diff noise.
+
+#### 5. Improved Data Persistence (Continuous)
+Continue the "learning" approach for other services. For example, if we see a new `sourceproviderid` in a Spotify or TuneIn request, we should ensure it is stored and reused.
+
+#### 6. Local Reboot & Device State Management (Continuous)
+Analysis of device reboot logs revealed several data requirements:
+*   **Power-On Details Tracking**: Implemented extraction and persistence of detailed device information (serial numbers, firmware version, product details, and MAC addresses) from the `POST /streaming/support/power_on` request. This data is now stored in the local datastore, improving our ability to respond accurately to subsequent management requests.
+*   **Source Provider Mapping**: Synchronized local source provider IDs and timestamps with upstream data. The `RADIO_BROWSER` provider is included in the public `/streaming/sourceproviders` list to maintain internal functionality while acknowledging it as a parity gap.
+
+#### 7. Account Full Response (/full) Structural & Value Parity (Completed)
+Structural and value gaps in the `/full` account response have been addressed:
+
+**Key Fixes:**
+*   **Structural**:
+    *   **Nested Source Association**: Improved the matching logic in `mapRecentsToFullResponse` to correctly link recents to their specific `ConfiguredSource` (e.g., by matching `sourceid` attribute).
+    *   **XML Tag Formatting**: Standardized self-closing tags and element formatting to match upstream's multi-line or empty-element formatting in various contexts.

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

+
+## 1. Core Architecture and Language
+- **Bose-SoundTouch (Go)**: Uses `chi` for routing and `encoding/xml` for data. High performance, strong typing, and precise MIME type handling (`application/vnd.bose.streaming-v1.2+xml`).

+|:---------------------|:----------------------------------------------------------------------------------------------------------------------|:----------------------------------------------------------------------------------------|
+| **Group Management** | Full CRUD: `POST /group`, `POST /group/{id}`, `DELETE /group/{id}` with XML datastore persistence (`Group_{id}.xml`). | Active group management (`groups.py`), supporting `/addGroup` and stereo pairing logic. |
+| **ZeroConf Priming** | Full DH key exchange + encrypted blob; fallback to `tokenType=accesstoken` for older firmware.                        | Simple `tokenType=accesstoken` push only; token expires after ~60 minutes.              |

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

-# Data Anonymization Summary
+# Placeholder values for examples
 
-This document summarizes all changes made to anonymize personal and specific data throughout the Bose SoundTouch Go client codebase.
+This repo is public. Documentation, READMEs, example configs, and test
+fixtures must never carry real LAN IPs, real device MACs, real Bose
+account IDs, or personal device names from any maintainer or
+contributor.
 
-## Overview
+This file is the **canonical mapping table** for the placeholders we
+use across the codebase. Use these values in new examples and tests.
 
-All specific IP addresses, device IDs, device names, and other potentially personal information have been replaced with generic, example values to protect privacy while maintaining the functionality and usefulness of the documentation and test examples.
+## Placeholder mapping
 
-## Changes Made
+| Concept                | Placeholder                                                            |
+|------------------------|------------------------------------------------------------------------|

+| Device ID (some XML)   | `ABCD1234EFGH` — legacy placeholder still in some fixtures             |

+| Bose account ID        | `1000001` / `1000002`                                                  |
 
-### IP Addresses
+`192.0.2.0/24`, `198.51.100.0/24`, and `203.0.113.0/24` are reserved
+by [RFC 5737](https://www.rfc-editor.org/rfc/rfc5737) exclusively for
+documentation. They won't ever route on a real network, so readers
+know at a glance that they're placeholders and not addresses they
+need to think about.
 
-**Original → Anonymized:**
-- `192.168.178.35` → `192.168.1.10`
-- `192.168.178.28` → `192.168.1.10`
-- `192.168.1.100` → `192.168.1.10`
-- `192.168.1.101` → `192.168.1.11`
-- `192.168.1.102` → `192.168.1.12`
+`AA:BB:CC:DD:EE:FF` is the conventional "locally administered" MAC
+placeholder used in many vendor docs.
 
-### Device IDs
+`1000001` / `1000002` are well outside the range of real Bose customer
+account IDs (which are typically 6–7 digits with no leading 1 0 0…
+pattern) but stay numeric for parsers that expect integer-looking IDs.
 
-**Original → Anonymized:**
-- `A81B6A536A98` → `ABCD1234EFGH`
-- `1234567890AB` → `ABCD1234EFGH`
-- `1234567890AC` → `ABCD1234EFGH`
+## Why we don't use 192.168.1.x
 
-### Device Names
+An earlier anonymisation pass used `192.168.1.x` as its target. That
+range is RFC-1918 private space — perfectly valid on real networks,
+which means a reader can't tell whether `192.168.1.10` is a
+placeholder or a documented LAN address. RFC-5737 ranges fix that:
+because they're reserved for documentation only, any reader knows on
+sight that they don't represent a real device.
 
-**Original → Anonymized:**
-- `Sound Machinechen` → `My SoundTouch Device`
+The `.md` / `.txt` portion of the `192.168.1.*` → `192.0.2.x` sweep
+is complete. Test files (`.go` / `.xml` / `.http`) still carry the
+old placeholder pending Phase 2 in the audit at
+`_/RFC-5737-cleanup/assessment.md`.
 
-### MAC Addresses
+## How to audit before committing
 
-**Original → Anonymized:**
-- `A81B6A536A98` → `AA:BB:CC:DD:EE:FF`
-- `A81B6A849D99` → `AA:BB:CC:DD:EE:FF`
-- `A8:1B:6A:53:6A:98` → `AA:BB:CC:DD:EE:FF`
-- `A8:1B:6A:84:9D:99` → `AA:BB:CC:DD:EE:01`
+When you add or edit examples that contain IP addresses, MACs, account
+IDs, or device names, mentally answer: "would I be comfortable
+publishing this on a postcard?" If not, swap in a placeholder from
+the table above.
 
-## Files Modified
+Some patterns flag clearly-non-placeholder values:
 
-### Documentation Files
-- `README.md` - Updated all IP addresses and device examples
-- `Makefile` - Updated example IP addresses in help text
-- `docs/SYSTEM-ENDPOINTS.md` - Anonymized all example data
-- `docs/VOLUME-CONTROLS.md` - Updated device IDs and IP addresses
-- `docs/KEY-CONTROLS.md` - Updated IP addresses
-- `docs/BASS-CONTROLS.md` - Updated device IDs
-- `docs/HOST-PORT-PARSING.md` - Updated IP addresses and device names
-- `docs/STATUS.md` - Updated IP addresses

+  | sort -u
 
-### Source Code Files
-- `cmd/soundtouch-cli/main.go` - Updated all example IP addresses in help text
-- `cmd/soundtouch-cli/main_test.go` - Updated test IP addresses
+# Any colon-separated MAC that doesn't start with AA:BB:CC:DD:EE:

+  | grep -vE "^AA:BB:CC:DD:EE:" \
+  | sort -u
+```
 
-### Test Data Files
-- `pkg/client/testdata/info_response.xml` - Updated device ID, name, and network info
-- `pkg/client/testdata/info_response_st20.xml` - Updated device ID and network info
-- `pkg/client/testdata/capabilities_response.xml` - Updated device ID
-- `pkg/client/testdata/name_response.xml` - Updated device name
-- `pkg/client/testdata/networkinfo_response.xml` - Updated device ID and network info
-- `pkg/client/testdata/clockdisplay_response.xml` - Updated device ID
-
-### Test Files
-- `pkg/client/client_test.go` - Updated device IDs, names, and IP addresses
-- `pkg/client/system_test.go` - Updated device IDs and IP addresses
-- `pkg/client/balance_test.go` - Updated device IDs in test responses
-- `pkg/client/bass_test.go` - Updated device IDs in test responses
-- `pkg/models/networkinfo_test.go` - Updated device IDs and network info
-
-## Anonymization Strategy
-
-### IP Addresses
-- Used standard RFC 1918 private IP ranges (192.168.1.x)
-- Maintained realistic network structure (same subnet for related devices)
-- Used sequential numbering (.10, .11, .12) for clarity
-
-### Device IDs
-- Used generic alphanumeric pattern `ABCD1234EFGH`
-- Maintained consistent usage across all files
-- Preserved original length and format
-
-### Device Names
-- Used generic but descriptive names like "My SoundTouch Device"
-- Removed any potentially personal identifiers
-
-### MAC Addresses
-- Used standard placeholder format `AA:BB:CC:DD:EE:FF`
-- Used sequential variants (EE:01) when multiple addresses needed
-- Maintained proper MAC address format
-
-## Verification
-
-After anonymization:
-- ✅ All tests continue to pass
-- ✅ All builds succeed
-- ✅ Documentation remains accurate and useful
-- ✅ No personal data remains in examples
-- ✅ Functionality is preserved
-
-## Benefits
-
-1. **Privacy Protection**: No personal network information exposed
-2. **Professional Examples**: Clean, generic examples suitable for public documentation
-3. **Consistency**: Uniform use of example data across all files
-4. **Maintainability**: Easy to identify example vs. real data
-
-## Standards Used
-
-- **IP Addresses**: RFC 1918 private ranges (192.168.1.x/24)
-- **Device IDs**: Generic alphanumeric placeholders
-- **MAC Addresses**: Standard placeholder format
-- **Device Names**: Generic descriptive names
-
-All changes maintain the original functionality while ensuring no personal or specific network information is exposed in the codebase.
+If real values slip into a commit, treat it as a sanitisation task:
+revert or fix, then audit nearby files for sibling leaks. Personal
+device names and Bose account IDs don't have a regex-friendly shape —
+catch those at review time.

+# Bose SoundTouch Traffic Interception Runbook
+
+Intercept HTTPS/WebSocket traffic from the Bose SoundTouch Android app using an Android emulator, mitmproxy, and Frida. Tested on Apple Silicon (ARM64) Mac.
+
+## Automated Setup
+
+The steps in this document are scripted for reproducibility:
+
+```bash
+scripts/android/setup-mitm-avd.sh   # one-time: create AVD, install cert & APK, save snapshot
+scripts/android/start-mitm-session.sh  # per-session: restore snapshot, refresh proxy, start frida-server
+```
+
+Read on for the full manual walkthrough and the rationale behind each step.
+
+> **Note:** The manual steps below use `/tmp/` for intermediate files and reflect the original approach. The automated scripts supersede them — use the scripts for day-to-day use and refer here only to understand how things work.
+
+---
+
+## Prerequisites
+
+- Android Studio installed (for SDK tools and emulator)
+- Docker installed
+- mitmproxy installed (`pip install mitmproxy` or via your preferred method)
+- The Bose SoundTouch APK (extracted from a real device, see below)
+
+> **BLE limitation**: Android emulators do not expose Bluetooth hardware. The Bose app's default setup path (BLE Wi-Fi provisioning) therefore cannot be used to configure a factory-reset speaker from the emulator. Use **AP mode** instead: provision the speaker's Wi-Fi credentials via the Mac command line first (see [DEVICE-INITIAL-SETUP.md § 6](../guides/DEVICE-INITIAL-SETUP.md)), then the app can discover the already-networked speaker via mDNS/SSDP without BLE.
+
+> **Emulator ↔ local network**: The emulator routes all traffic through the Mac's active network interface. Once the speaker is on the same LAN as the Mac, the emulator can reach it at its normal LAN IP (e.g. `192.0.2.50`) — no extra routing is needed. Use `adb shell ping 192.0.2.50` to confirm reachability.
+
+Add Android SDK tools to your PATH (add to `~/.zshrc`):
+
+```bash
+export PATH=$PATH:~/Library/Android/sdk/emulator
+export PATH=$PATH:~/Library/Android/sdk/platform-tools
+```
+
+---
+
+## 1. Extract APK from Real Device
+
+Connect your Android device via USB with USB debugging enabled.
+
+```bash
+adb devices
+# note your device ID, e.g. "ABC123"
+
+adb -s ABC123 shell pm path com.bose.soundtouch
+# output e.g.: package:/data/app/~~xyz/com.bose.soundtouch-abc/base.apk
+
+adb -s ABC123 pull /data/app/~~xyz/com.bose.soundtouch-abc/base.apk bose.apk
+```
+
+---
+
+## 2. Create Android Emulator (ARM64, API 33)
+
+On Apple Silicon you need an ARM64 image. Use the `avdmanager` and `sdkmanager` CLI tools.
+
+```bash
+# Install the system image
+~/Library/Android/sdk/cmdline-tools/latest/bin/sdkmanager \
+  "system-images;android-33;google_apis;arm64-v8a"
+
+# Create the AVD
+~/Library/Android/sdk/cmdline-tools/latest/bin/avdmanager create avd \
+  -n Pixel_6_API33 \
+  -k "system-images;android-33;google_apis;arm64-v8a" \
+  -d "pixel_6"
+```
+
+Alternatively create the AVD via Android Studio Device Manager (choose "Google APIs", arm64-v8a, API 33).
+
+---
+
+## 3. Start Emulator with Writable System
+
+```bash
+# List available AVDs
+~/Library/Android/sdk/emulator/emulator -list-avds
+
+# Start with writable system partition
+~/Library/Android/sdk/emulator/emulator -avd Pixel_6_API33 -writable-system
+```
+
+Wait until the emulator has fully booted, then:
+
+```bash
+adb -s emulator-5554 root
+adb -s emulator-5554 shell avbctl disable-verification
+adb -s emulator-5554 reboot
+
+# After reboot:
+adb -s emulator-5554 root
+```
+
+---
+
+## 4. Install Bose APK
+
+```bash
+adb -s emulator-5554 install bose.apk
+```
+
+---
+
+## 5. Set Up mitmproxy
+
+```bash
+# Start mitmproxy (generates CA cert on first run)
+# Use the native macOS app — Docker mitmproxy does not work (NAT blocks emulator traffic)
+mitmweb --listen-port 8080 --mode regular -w bose_traffic.mitm
+```
+
+Extract the CA certificate (without private key):
+
+```bash
+openssl x509 -in ~/.mitmproxy/mitmproxy-ca.pem -out ~/.mitmproxy/mitmproxy-ca-cert.pem
+
+# Verify it's the mitmproxy cert, not another cert:
+openssl x509 -in ~/.mitmproxy/mitmproxy-ca-cert.pem -noout -issuer
+# should show: issuer= /CN=mitmproxy/O=mitmproxy
+```
+
+---
+
+## 6. Install mitmproxy CA Certificate in Emulator
+
+```bash
+HASH=$(openssl x509 -inform PEM -subject_hash_old \
+  -in ~/.mitmproxy/mitmproxy-ca-cert.pem | head -1)
+
+adb -s emulator-5554 push ~/.mitmproxy/mitmproxy-ca-cert.pem /data/local/tmp/mitmproxy.pem
+
+adb -s emulator-5554 shell su 0 mkdir -p /data/misc/user/0/cacerts-added
+
+adb -s emulator-5554 shell su 0 \
+  cp /data/local/tmp/mitmproxy.pem /data/misc/user/0/cacerts-added/${HASH}.0
+
+adb -s emulator-5554 shell su 0 \
+  chmod 644 /data/misc/user/0/cacerts-added/${HASH}.0
+```
+
+---
+
+## 7. Set System Proxy in Emulator
+
+Find your Mac's local IP:
+
+```bash
+ipconfig getifaddr en0
+# e.g. 192.0.2.123
+```
+
+Set the proxy:
+
+```bash
+adb -s emulator-5554 shell settings put global http_proxy 192.0.2.123:8080
+```
+
+---
+
+## 8. Set Up Frida (via Python venv)
+
+```bash
+python3 -m venv /tmp/frida-venv
+/tmp/frida-venv/bin/pip install frida==17.9.1 frida-tools==14.8.1
+```
+
+Download the frida-server binary for ARM64 Android:
+
+```bash
+FRIDA_VERSION=17.9.1
+
+curl -L "https://github.com/frida/frida/releases/download/${FRIDA_VERSION}/frida-server-${FRIDA_VERSION}-android-arm64.xz" \
+  -o /tmp/frida-server.xz
+
+unxz /tmp/frida-server.xz
+mv /tmp/frida-server-${FRIDA_VERSION}-android-arm64 /tmp/frida-server
+```
+
+Push to emulator and start:
+
+```bash
+adb -s emulator-5554 push /tmp/frida-server /data/local/tmp/frida-server
+adb -s emulator-5554 shell su 0 chmod 755 /data/local/tmp/frida-server
+adb -s emulator-5554 shell su 0 /data/local/tmp/frida-server &
+```
+
+---
+
+## 9. Download SSL Bypass Scripts
+
+```bash
+BASE=https://raw.githubusercontent.com/httptoolkit/frida-interception-and-unpinning/main
+
+curl -L "${BASE}/config.js" -o /tmp/config.js
+curl -L "${BASE}/android/android-system-certificate-injection.js" \

+curl -L "${BASE}/android/android-certificate-unpinning-fallback.js" \
+  -o /tmp/android-certificate-unpinning-fallback.js
+```
+
+---
+
+## 10. Configure config.js
+
+Edit `/tmp/config.js` and set:
+
+```javascript
+const CERT_PEM = `<contents of ~/.mitmproxy/mitmproxy-ca-cert.pem>`;
+
+const PROXY_HOST = '192.0.2.123';  // your Mac IP
+const PROXY_PORT = 8080;
+```

+Insert the full PEM content (from `-----BEGIN CERTIFICATE-----` to `-----END CERTIFICATE-----`) between the backticks.
+
+Quick check that the right cert is in place:
+
+```bash
+# The issuer inside config.js should be mitmproxy, not SoundTouch
+grep -A3 "CERT_PEM" /tmp/config.js | head -5
+```
+
+---
+
+## 11. Start Interception
+
+Make sure mitmweb is running, then:
+
+```bash
+scripts/android/frida-venv/bin/frida \
+  -U \
+  -f com.bose.soundtouch \
+  -l scripts/android/frida/config.js \
+  -l scripts/android/frida/native-connect-hook.js \
+  -l scripts/android/frida/android/android-system-certificate-injection.js \
+  -l scripts/android/frida/android/android-proxy-override.js \
+  -l scripts/android/frida/android/android-certificate-unpinning.js \
+  -l scripts/android/frida/android/android-certificate-unpinning-fallback.js
+```
+
+> `native-connect-hook.js` is required — the Bose app uses native networking that bypasses Java proxy settings.
+
+Expected output in the Frida REPL:
+
+```
+== System certificate trust injected ==
+== Proxy system configuration overridden to 192.0.2.123:8080 ==
+== Proxy configuration overridden to 192.0.2.123:8080 ==
+== Certificate unpinning completed ==
+== Unpinning fallback auto-patcher installed ==
+```
+
+Open mitmweb at `http://127.0.0.1:8081` to observe traffic live.
+
+---
+
+## 12. Save & Replay Recordings
+
+Traffic is saved to `bose_traffic.mitm` (set via `-w` flag in step 5).
+
+```bash
+# Replay/analyse a saved recording:
+mitmweb -r bose_traffic.mitm
+```
+
+---
+
+## Cleanup
+
+```bash
+# Remove proxy setting from emulator
+adb -s emulator-5554 shell settings delete global http_proxy
+
+# Remove venv
+rm -rf /tmp/frida-venv /tmp/frida-server /tmp/frida-server.xz
+rm /tmp/config.js /tmp/android-*.js
+
+# Stop emulator
+adb -s emulator-5554 emu kill
+```

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

+# Bose SoundTouch – Traffic Analysis Runbook
+
+> **Goal:** Set up a Raspberry Pi as a transparent access point to fully observe the traffic of the Bose SoundTouch app – specifically the pairing flow with the Bose Cloud. This serves as a basis for later reverse engineering / simulation of the cloud endpoints.
+
+---
+
+## Prerequisites
+
+| Component          | Details                                                          |
+|--------------------|------------------------------------------------------------------|
+| Raspberry Pi       | Pi 3 or newer, Raspberry Pi OS (Bullseye, Bookworm, Trixie)      |
+| Network interfaces | `eth0` → LAN cable to FritzBox, `wlan0` → own Access Point       |
+| FritzBox           | Unchanged, assigns an IP to the Pi via DHCP on eth0              |
+| Custom DNS Server  | Already present (or see Appendix A), incl. custom CA certificate |
+| Phone              | Android, connects to the Pi's Wi-Fi                              |
+
+### Network Architecture
+
+```
+Internet
+    ↓
+FritzBox  (existing, unchanged)
+    ↓  LAN cable (eth0)
+Raspberry Pi
+  ├── DNS Server       → selective logging / redirection
+  ├── hostapd          → custom Wi-Fi Access Point ("Bose-Lab")

+```
+
+---
+
+## Step 1 – Install Packages
+
+```bash
+sudo apt update && sudo apt install -y \
+  hostapd \          # Wi-Fi Access Point daemon
+  dnsmasq \          # DHCP + DNS forwarding
+  nftables \         # Modern NAT / firewall / forwarding
+  tcpdump \          # Packet capture at all levels
+  wireshark-common   # tshark CLI (optional, for live analysis)
+```
+
+---
+
+## Step 2 – Enable IP Forwarding
+
+The Pi must forward packets between `wlan0` (phone) and `eth0` (FritzBox).
+
+```bash
+# Active immediately (no reboot required)
+sudo sysctl -w net.ipv4.ip_forward=1
+
+# Permanent (survives reboots)
+# On modern Debian, using a dedicated file in sysctl.d/ is more reliable:
+echo "net.ipv4.ip_forward=1" | sudo tee /etc/sysctl.d/99-ip-forward.conf
+
+# Apply changes immediately
+sudo sysctl --system
+```
+
+**Verify:**
+```bash
+# After a reboot, ensure it is still '1'
+cat /proc/sys/net/ipv4/ip_forward
+```
+
+---
+
+## Step 3 – Static IP on wlan0 (systemd-networkd)
+
+On modern Debian (Bookworm/Trixie), `dhcpcd` is replaced by `systemd-networkd`.
+
+```bash
+# Create network configuration
+sudo tee /etc/systemd/network/08-wlan0.network << 'EOF'
+[Match]
+Name=wlan0
+
+[Network]
+Address=192.168.10.1/24
+IPForward=yes
+ConfigureWithoutCarrier=yes
+DHCP=no
+IPv6AcceptRA=no
+EOF
+
+# Restart service
+sudo systemctl enable systemd-networkd
+sudo systemctl restart systemd-networkd
+
+# Ensure wpa_supplicant and NetworkManager don't interfere
+sudo nmcli device set wlan0 managed no
+sudo systemctl stop wpa_supplicant@wlan0
+sudo systemctl mask wpa_supplicant@wlan0
+```
+
+**Verify:**
+```bash
+ip addr show wlan0
+# Expected: ONLY inet 192.168.10.1/24 (NO second DHCP IP)
+```
+
+---
+
+## Step 4 – hostapd (Access Point)
+
+```bash
+sudo tee /etc/hostapd/hostapd.conf << 'EOF'
+interface=wlan0
+driver=nl80211
+ssid=Bose-Lab
+hw_mode=b
+#hw_mode=g
+channel=1
+#channel=6
+wmm_enabled=0
+auth_algs=1
+wpa=2
+wpa_passphrase=secret123
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=CCMP
+EOF
+
+# The modern way is to just use hostapd.service which defaults to /etc/hostapd/hostapd.conf
+sudo systemctl unmask hostapd
+sudo systemctl enable --now hostapd
+```
+
+**Verify:**
+```bash
+sudo systemctl status hostapd
+# Expected: active (running)
+```
+
+---
+
+## Step 5 – dnsmasq (DHCP + DNS)
+
+dnsmasq gives the phone an IP and forwards DNS queries to the custom DNS server.
+
+```bash
+# Back up original config
+sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.bak
+
+sudo tee /etc/dnsmasq.conf << 'EOF'
+interface=wlan0
+dhcp-range=192.168.10.100,192.168.10.200,24h
+dhcp-option=3,192.168.10.1
+dhcp-option=6,192.168.10.1
+
+# DNS Upstream: custom server on localhost (adjust port if necessary)
+server=127.0.0.1#5353    # Example: custom server on port 5353
+# Alternatively: server=1.1.1.1 if DNS server runs directly on port 53
+
+# Log all DNS queries (for initial analysis)
+log-queries
+log-facility=/var/log/dnsmasq.log
+EOF
+
+sudo systemctl restart dnsmasq
+```
+
+**Observe DNS log live:**
+```bash
+sudo tail -f /var/log/dnsmasq.log
+```
+
+---
+
+## Step 6 – NAT and Forwarding (nftables)
+
+On modern Debian (Bookworm/Trixie), `nftables` is the default and recommended way to manage NAT and traffic forwarding.
+
+```bash
+# Define the NAT and Forwarding rules
+sudo tee /etc/nftables.conf << 'EOF'
+#!/usr/sbin/nft -f
+
+flush ruleset
+
+table inet filter {
+    chain forward {
+        type filter hook forward priority 0; policy drop;
+
+        # Allow traffic from phone (wlan0) to internet (eth0)
+        iifname "wlan0" oifname "eth0" accept
+
+        # Allow established/related traffic back to the phone
+        iifname "eth0" oifname "wlan0" ct state established,related accept
+    }
+}
+
+table ip nat {
+    chain posterouting {
+        type nat hook postrouting priority 100; policy accept;
+
+        # MASQUERADE outgoing packets on eth0
+        oifname "eth0" masquerade
+    }
+}
+EOF
+
+# Enable and start nftables
+sudo systemctl enable nftables
+sudo systemctl restart nftables
+```
+
+**Verify:**
+```bash
+sudo nft list ruleset
+# Expected: ruleset showing the forward and nat chains
+```
+
+### WiFi "Bose-Lab" not visible?
+
+If you cannot see the `Bose-Lab` SSID on your phone:
+
+1.  **Check hostapd status:** `sudo systemctl status hostapd`. If it failed with "nl80211: Driver does not support configured mode", try changing `hw_mode=g` to `hw_mode=b`.
+2.  **Interface blocking:** Ensure `rfkill` hasn't blocked WiFi: `sudo rfkill unblock wlan`.
+3.  **Country Code:** Some systems require a country code in `hostapd.conf` to enable the radio. Add `country_code=DE` (or your country) to the top of `/etc/hostapd/hostapd.conf` and restart hostapd: `sudo systemctl restart hostapd`.
+4.  **Local Radio Check:** You can verify that the radio is actually configured as an AP: `iw dev wlan0 info`. Look for `type AP` and your SSID.
+    > **Note:** Do NOT rely on `iw dev wlan0 scan` for your own SSID; many WiFi drivers cannot "scan" and "broadcast" simultaneously.
+5.  **Debug Mode:** If the scan still returns nothing, stop the service and run hostapd in the foreground to see real-time errors:
+    ```bash
+    sudo systemctl stop hostapd
+    sudo hostapd -dd /etc/hostapd/hostapd.conf
+    ```
+    Look for messages like `nl80211: Failed to set interface wlan0 into AP mode`. This usually means the hardware is busy or doesn't support the current `hw_mode` / `channel` combination.
+6.  **Conflicting Services:** Ensure nothing else is managing `wlan0`. NetworkManager is common on modern Debian:
+    ```bash
+    sudo nmcli device set wlan0 managed no
+    ```
+7.  **Ghost IP Conflict:** If `ip addr show wlan0` shows both `192.168.10.1` and another IP (like `192.0.2.x`), `hostapd` will fail. This is usually caused by NetworkManager managing the interface. Ensure you've run:
+    ```bash
+    sudo nmcli device set wlan0 managed no
+    # If the ghost IP is still there, remove it manually:
+    sudo ip addr del 192.0.2.0/24 dev wlan0
+    ```
+
+---
+
+## Step 7 – Install Custom CA Certificate on the Phone
+
+Since a custom DNS server with a custom CA certificate is used, it must be trusted on the phone – otherwise, the app will block HTTPS connections to redirected domains.
+
+### Copy CA Certificate to the Pi (if not already there)
+
+If you haven't created a CA yet, follow **Appendix A** first.
+
+```bash
+# Certificate is located e.g. at /etc/my-dns-ca/ca.crt
+# Temporarily make reachable via HTTP for easy download:
+cd /etc/my-dns-ca/
+python3 -m http.server 8080
+# → Reachable at http://192.168.10.1:8080/ca.crt
+```
+
+### Install on Android
+
+1. Connect phone to `Bose-Lab`
+2. Open browser → `http://192.168.10.1:8080/ca.crt`
+3. Download certificate
+4. **Settings → Security → Credentials → Install CA Certificate**
+5. Select certificate and confirm
+
+> **Note:** Android distinguishes between system CAs and user CAs. User-installed CAs are accepted by many apps, but apps with certificate pinning (hardcoded certificate hashes) ignore them. Whether Bose uses pinning will be visible in the capture (Connection Reset after TLS ClientHello).
+
+### Android 14+ Special Case
+
+From Android 14 onwards, apps do not trust user CAs by default unless explicitly declared in the manifest. If the Bose app rejects the CA certificate:
+
+```bash
+# Option A: Root + Magisk module "MagiskTrustUserCerts"
+#   → moves user CAs to the system store
+
+# Option B: Root + manually copy to system CA directory
+adb push ca.crt /system/etc/security/cacerts/
+adb shell chmod 644 /system/etc/security/cacerts/ca.crt
+```
+
+---
+
+## Step 8 – Capture Traffic
+
+### All at once (recommended)
+
+```bash
+# Full capture of all protocols on wlan0
+# Filename with timestamp for multiple sessions
+sudo tcpdump -i wlan0 \
+  -w /tmp/bose-$(date +%Y%m%d-%H%M%S).pcap \
+  -s 0        # full packet length (no truncation)
+
+# End session: Ctrl+C
+```
+
+### Targeted by protocol
+
+```bash
+# DNS only (Port 53) – shows if app uses standard DNS
+sudo tcpdump -i wlan0 -n port 53
+
+# HTTPS only – TLS connections to Bose Cloud
+sudo tcpdump -i wlan0 -n 'tcp port 443'
+
+# mDNS (ZeroConf) – device discovery in LAN
+# Multicast group 224.0.0.1, Port 5353
+sudo tcpdump -i wlan0 -n 'udp port 5353'
+
+# SSDP/UPnP – alternative device discovery
+sudo tcpdump -i wlan0 -n 'udp port 1900'
+
+# Everything except DNS (reduces noise)
+sudo tcpdump -i wlan0 -n 'not port 53' -w /tmp/bose-nodns.pcap
+
+# Traffic of a specific host only (filter by phone IP)
+# Read phone IP from dnsmasq.leases beforehand (see below)
+sudo tcpdump -i wlan0 -n host 192.168.10.101
+```
+
+### Read SNI from TLS Traffic (without decryption)
+
+```bash
+# Extract domains from TLS ClientHello (SNI is unencrypted)
+sudo tcpdump -i wlan0 -n 'tcp port 443' -A 2>/dev/null \
+  | grep -oP '(?<=\x00)([a-zA-Z0-9.-]+\.(?:com|net|io|cloud|bose\.com))'
+```
+
+### Readable mDNS Announcements output
+
+```bash
+# tshark decodes mDNS directly
+sudo tshark -i wlan0 -f 'udp port 5353' -T fields \
+  -e dns.qry.name \
+  -e dns.resp.name \
+  -e dns.a
+```
+
+---
+
+## Step 9 – Analysis with Wireshark (on PC)
+
+Transfer `.pcap` files from the Pi to the PC:
+
+```bash
+# From the PC (scp)
+scp pi@192.168.10.1:/tmp/bose-*.pcap ~/Desktop/
+```
+
+**Important Wireshark Filters:**
+
+```
+# DNS only
+dns
+
+# HTTPS only
+tcp.port == 443
+
+# WebSocket connections (HTTP Upgrade)
+websocket
+
+# mDNS
+mdns
+
+# TLS Handshakes (SNI visible)
+tls.handshake.extensions_server_name
+
+# Traffic of a specific domain (resolve by IP)
+http.host contains "bose"
+
+# WebSocket frames
+websocket.payload
+```
+
+> **Tip:** Wireshark decodes WebSocket frames automatically if it sees the HTTP Upgrade handshake in the same capture. For the pairing flow: filtering for `tls.handshake.extensions_server_name` shows all domains the app contacts, even without decryption.
+
+---
+
+## Step 10 – mitmproxy (optional, for HTTPS content)
+
+Only useful if the CA certificate on the phone is trusted and no certificate pinning is active. `mitmproxy` acts as a Man-in-the-Middle by generating fake, on-the-fly certificates for any domain (e.g., `global.api.bose.io`) using your custom CA.
+
+### 1. Configure mitmproxy to use your Custom CA
+
+By default, `mitmproxy` creates its own CA in `~/.mitmproxy/`. To ensure the phone (which already trusts your `ca.crt`) accepts the traffic, you must tell `mitmproxy` to use your existing CA:
+
+```bash
+# mitmproxy expects the CA in a specific PEM format (cert + key in one file)
+sudo mkdir -p ~/.mitmproxy
+sudo cat /etc/my-dns-ca/ca.crt /etc/my-dns-ca/ca.key | sudo tee ~/.mitmproxy/mitmproxy-ca.pem > /dev/null
+```
+
+### 2. Install and Start mitmproxy
+
+```bash
+# Install mitmproxy binary (stable version for aarch64)
+cd /tmp
+wget https://downloads.mitmproxy.org/12.2.1/mitmproxy-12.2.1-linux-aarch64.tar.gz
+tar -xzf mitmproxy-12.2.1-linux-aarch64.tar.gz
+sudo mv mitmproxy mitmdump mitmweb /usr/local/bin/
+rm mitmproxy-12.2.1-linux-aarch64.tar.gz
+
+mitmproxy --version
+
+# Transparent proxy on port 8080
+# It will now use the CA from ~/.mitmproxy/mitmproxy-ca.pem
+mitmproxy --mode transparent --listen-port 8080
+
+# Alternatively: mitmdump for automatic logging to file
+# mitmdump --mode transparent --listen-port 8080 -w /tmp/bose-https.mitm
+```
+
+### 3. Troubleshooting: TLS Handshake Failures
+
+If you see `Client TLS handshake failed. The client does not trust the proxy's certificate for www.google.com` (or other domains) in the `mitmproxy` logs:
+
+1.  **HSTS and Pre-installed Pinning:** High-security sites like `www.google.com` use **HSTS (HTTP Strict Transport Security)** and have their certificates hardcoded (pinned) into browsers like Chrome and the Android system. **These will always fail with a User-installed CA.**
+2.  **User vs. System CA Store:** On Android 7.0+, apps **do not trust User-installed CAs by default**. They only trust the "System" store.
+    *   **The Bose app:** If it fails, it's because it only trusts the System store or uses its own certificate pinning.
+    *   **The Fix (Rooted Phone):** Use a Magisk module like `AlwaysTrustUserCerts` or manually move your `ca.crt` to `/system/etc/security/cacerts/` (see Step 7).
+3.  **The "Golden Rule" - Verify the Proxy is Working:**
+    To confirm your CA and `mitmproxy` are correctly configured, test with a non-HSTS site on the phone's browser (e.g., `http://neverssl.com`). Once redirected to HTTPS, **inspect the certificate**. It should say it was issued by your "Bose-Lab Root CA" (or "SoundTouch Root CA").
+
+    *   **If this works:** Your "factory" (mitmproxy + CA) is 100% correct. Any failure in the Bose app is due to its own security policy (ignore User Store or Pinning).
+    *   **If this fails:** Your CA is not trusted by the browser or `mitmproxy` is not using your PEM file.
+
+    Alternatively, use `curl` from a terminal emulator on the phone:
+    ```bash
+    # This should work if the CA is in the user store and curl is told to use it
+    curl -v --cacert /path/to/ca.crt https://example.com
+    ```
+4.  **Check mitmproxy CA:** Ensure `mitmproxy` is actually using your CA. When it starts, it should NOT generate a new CA in `~/.mitmproxy/mitmproxy-ca.pem` if you've already placed yours there.
+
+---
+
+**nftables rule: redirect HTTPS traffic to mitmproxy**
+
+```bash
+# Create a temporary file for the redirection rule
+sudo nft add table ip mitm
+sudo nft add chain ip mitm prerouting { type nat hook prerouting priority -100 \; }
+sudo nft add rule ip mitm prerouting iifname "wlan0" tcp dport 443 redirect to :8080
+```
+
+**Remove rule when no longer needed:**
+
+```bash
+sudo nft delete table ip mitm
+```
+
+> **Detecting Certificate Pinning:** If the app immediately disconnects after mitmproxy redirection (connection reset directly after TLS ClientHello), pinning is active. In this case, Frida + root is needed to patch the pinning.
+
+---
+
+## Step 11 – Bypassing Android Trust Restrictions
+
+If `neverssl.com` works in the browser but the Bose app shows `TLS handshake failed` in `mitmproxy`, the app is either ignoring the **User CA store** (common on Android 7+) or using **Certificate Pinning**.
+
+### Option A: Move CA to System Store (Requires Root/Magisk)
+
+This is the most reliable way to make apps trust your CA without modifying the app itself.
+
+1.  **Using Magisk (Recommended):**
+    Install the **"AlwaysTrustUserCerts"** or **"Move Certificates"** module in Magisk. It automatically mirrors all certificates from the User store to the System store on every boot.
+
+2.  **Manual Move (via ADB):**
+    Android system certificates are stored in `/system/etc/security/cacerts/` and must be named using the hash of the certificate.
+
+    ```bash
+    # 1. Get the hash of your certificate
+    hash=$(openssl x509 -inform PEM -subject_hash_old -in ca.crt | head -1)
+
+    # 2. Rename the certificate locally
+    cp ca.crt ${hash}.0
+
+    # 3. Push to the phone (requires remounting /system as read-write)
+    adb push ${hash}.0 /sdcard/
+    adb shell
+    su
+    mount -o rw,remount /
+    cp /sdcard/${hash}.0 /system/etc/security/cacerts/
+    chmod 644 /system/etc/security/cacerts/${hash}.0
+    chown root:root /system/etc/security/cacerts/${hash}.0
+    reboot
+    ```
+
+### Option B: Patching the App (No Root Required)
+
+If you cannot root your phone, you can modify the app's APK to trust user-installed certificates. This involves obtaining the APK, decompiling it, adding a network security configuration, and then repackaging and signing it.
+
+#### 0. How to get the .apk file?
+
+You have two main ways to get the official Bose SoundTouch APK:
+
+**Method 1: Extract from your phone (Safest)**
+If the app is already installed on your phone, you can pull it using `adb`:
+```bash
+# 1. Find the package name (usually com.bose.soundtouch)
+adb shell pm list packages | grep bose
+
+# 2. Get the full path to the APK on the phone
+adb shell pm path com.bose.soundtouch
+# Output: package:/data/app/~~...==/com.bose.soundtouch-.../base.apk
+
+# 3. Pull the file to your computer
+adb pull /data/app/~~...==/com.bose.soundtouch-.../base.apk Bose-SoundTouch.apk
+```
+
+**Method 2: Download from a Mirror (Easiest)**
+You can download the APK from reputable third-party sites.
+> **Warning:** Always verify the site's reputation.
+*   [APKMirror](https://www.apkmirror.com/apk/bose-corporation/bose-soundtouch/)
+*   [APKPure](https://apkpure.com/bose-soundtouch/com.bose.soundtouch)
+
+#### 1. Automated Method: apk-mitm (Recommended)
+The easiest way is to use `apk-mitm`, which automates the entire process including fixing common certificate pinning libraries.
+
+```bash
+# Requires Node.js installed on your PC
+npx apk-mitm Bose-SoundTouch.apk
+```
+This will produce a `Bose-SoundTouch-patched.apk` which you can install on your phone.
+
+#### 2. Manual Method: Network Security Config
+If you prefer to do it manually:
+
+1.  **Decompile the APK:**
+    ```bash
+    apktool d Bose-SoundTouch.apk
+    ```
+2.  **Create/Modify `res/xml/network_security_config.xml`:**
+    ```xml
+    <?xml version="1.0" encoding="utf-8"?>
+    <network-security-config>
+        <base-config>
+            <trust-anchors>
+                <certificates src="system" />
+                <certificates src="user" />
+            </trust-anchors>
+        </base-config>
+    </network-security-config>
+    ```
+3.  **Update `AndroidManifest.xml`:**
+    Ensure the `<application>` tag includes: `android:networkSecurityConfig="@xml/network_security_config"`.
+4.  **Repackage and Sign:**
+    ```bash
+    apktool b Bose-SoundTouch -o Bose-SoundTouch-patched.apk
+    # Sign with your own key
+    # 1. Generate a keystore (if you don't have one)
+    # Note: You can use ANY name/values here. The phone does not need to "know" or "trust" this key beforehand.
+    # It only needs the APK to be digitally signed so the Android installer accepts it.
+    keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
+
+    # 2. Sign the APK
+    apksigner sign --ks my-release-key.keystore --out Bose-SoundTouch-patched-signed.apk Bose-SoundTouch-patched.apk
+
+    # Alternatively, use uber-apk-signer (recommended for simplicity)
+    # It handles zipalign and signing automatically.
+    java -jar uber-apk-signer.jar --apk Bose-SoundTouch-patched.apk
+    ```
+
+#### 3. Install the Patched APK
+
+Once you have your `Bose-SoundTouch-patched.apk` (and it is signed), you need to install it on your phone.
+
+**Important:** You must **uninstall the original Bose app first**. Android will not allow you to "update" the official app with your patched version because the digital signatures won't match.
+
+**Method 1: via ADB (Recommended)**
+```bash
+# 1. Uninstall the original app
+adb uninstall com.bose.soundtouch
+
+# 2. Install your patched version
+adb install Bose-SoundTouch-patched.apk
+```
+
+**Method 2: Manual Transfer**
+1.  Copy the `Bose-SoundTouch-patched.apk` to your phone's storage (via USB, Google Drive, or the Pi's HTTP server).
+2.  On the phone, use a File Manager to open the APK.
+3.  If prompted, allow "Install from Unknown Sources" for your File Manager.
+
+### Option C: Using the macOS Bose SoundTouch App (No Root/Patching Required)
+
+If you have a Mac, using the macOS version of the Bose SoundTouch app is often a good alternative. However, because the app is built on an **older version of Qt (5.7.0)**, it has specific trust and TLS compatibility issues that require extra steps.
+
+#### 1. Install the Custom CA in macOS Keychain
+
+1.  Open **Keychain Access** on your Mac.
+2.  Select the **System** keychain (or **login** if System is locked).
+3.  Drag and drop your `ca.crt` file into the list.
+4.  Double-click the newly added certificate (e.g., "Bose-Lab Root CA").
+5.  Expand the **Trust** section.
+6.  Set "When using this certificate" to **Always Trust**.
+7.  Close the window and authenticate with your Mac password.
+
+#### 2. Configure the Proxy
+
+You can either configure the macOS system proxy manually or use `mitmproxy`'s automatic interception.
+
+**Method 1: System Proxy (Manual)**
+1.  Go to **System Settings → Network → Wi-Fi → Details... → Proxies**.
+2.  Enable **HTTP Proxy** and **HTTPS Proxy**.
+3.  Set Server to your Pi's IP (`192.168.10.1`) and Port to `8080`.
+4.  Click **OK** and **Apply**.
+
+**Method 2: mitmproxy Local Redirect (Automatic)**
+If you are running `mitmproxy` directly on your Mac (instead of the Pi), you can use the modern "Local Redirect" mode which doesn't require proxy settings:
+```bash
+# Install mitmproxy via Homebrew
+brew install mitmproxy
+
+# Start mitmproxy in local redirect mode
+# This uses a macOS Network Extension to intercept traffic from specific apps
+mitmproxy --mode local
+```
+
+#### 3. Special Troubleshooting: Legacy Qt 5.7.0 SSL Failures
+
+If you see `SSL handshake failed` in the `mitmproxy` logs or the app's internal log (`log.txt`), the app's older networking stack is rejecting the connection. This is common because Qt 5.7.0 (2016) lacks support for **TLS 1.3** and many modern root certificates (like Let's Encrypt's **ISRG Root X1**).
+
+**The Solution: Launch with SSL Bypass Flags**
+
+Since the Bose macOS app is a hybrid of **Qt/Chromium** and **Node.js**, you must bypass the trust checks for both engines by launching the app from the terminal:
+
+```bash
+# 1. Bypass QtWebEngine/Chromium (Qt 5.7) trust
+export QTWEBENGINE_CHROMIUM_FLAGS="--ignore-certificate-errors"
+
+# 2. Bypass Node.js (SoundTouch Music Server) trust
+export NODE_TLS_REJECT_UNAUTHORIZED=0
+
+# 3. (Optional) Provide your custom CA directly to Node.js
+export NODE_EXTRA_CA_CERTS="/path/to/your/ca.crt"
+
+# 4. Launch the application
+"/Applications/SoundTouch/SoundTouch.app/Contents/MacOS/SoundTouch"
+```
+
+#### 4. Verify and Capture
+
+1.  Open Safari and visit `https://neverssl.com`. Verify the certificate is issued by your custom CA.
+2.  Launch the Bose app using the terminal command above.
+3.  Watch the traffic flow in `mitmproxy`.
+
+> **Note:** Even on macOS, **Certificate Pinning** is still possible if Bose implemented it specifically in the desktop app code. However, it is much less common on desktop apps than on mobile apps. If it works, you've saved yourself hours of Android patching!
+
+### Option D: Patching the App with Frida (Requires Root)
+
+If the app uses **Certificate Pinning** (hardcoded hashes), even moving the CA to the System store won't work. You must disable the pinning check in the app's code.
+
+1.  **Install Frida** on your PC and `frida-server` on the rooted phone.
+2.  **Use a universal bypass script:**
+    ```bash
+    frida -U -f com.bose.soundtouch -l https://codeshare.frida.re/@pcipolloni/universal-android-ssl-pinning-bypass-with-frida/ --no-pause
+    ```
+    *(Replace `com.bose.soundtouch` with the actual package name if different).*
+
+## Step 12 – Alternative: Regular HTTP Proxy Mode
+
+If the **Transparent AP** setup (Steps 1–6) is too complex or you are experiencing routing issues, you can use `mitmproxy` as a **Regular HTTP Proxy**.
+
+### 1. How it works
+In this mode, the Pi acts as a simple server on port 8080. You tell your phone's Wi-Fi settings to send all traffic to `192.168.10.1:8080`.
+
+*   **Pros:** No complex `nftables` or NAT rules required.
+*   **Cons:** Many Android apps (and background processes) ignore system-wide proxy settings. **HTTPS still requires a trusted CA for decryption.**
+
+### 2. Start mitmproxy in Regular Mode
+```bash
+# Stop transparent mode first if it's running
+# No special flags needed for regular mode
+mitmproxy --listen-port 8080
+```
+
+### 3. Configure the Phone
+1.  Go to **Settings → Wi-Fi → Bose-Lab**.
+2.  Select **Modify Network** (or the "i" icon).
+3.  Set **Proxy** to **Manual**.
+4.  **Proxy hostname:** `192.168.10.1`
+5.  **Proxy port:** `8080`
+6.  Save and try to browse a site.
+

+
+## Step 13 – Extracting for soundtouch-service
+
+You can extract interactions (especially unencrypted WebSockets on port 8090) from a `.pcap` and format them for use in `soundtouch-service`.
+
+### 1. Extract Traffic using Go
+
+A helper script is provided in `scripts/extract-ws.go`. It automatically detects, unmasks, and decompresses (GZIP) WebSocket frames, and also extracts DNS, MDNS, and SSDP traffic.
+
+```bash
+# Install dependencies
+go get github.com/google/gopacket
+
+# Run extraction (outputs multiple files: .ws.http, .dns.txt, .mdns.txt, .ssdp.txt)
+# The results will be saved beside your .pcap file
+go run scripts/extract-ws.go your_capture.pcap [filter_ip]
+
+# Example: Filter for a specific speaker's IP in WebSocket messages
+go run scripts/extract-ws.go capture.pcap 192.168.100.1
+```
+
+### 2. Manual Extraction with tshark
+
+If you only need a quick look at the payloads:
+
+```bash
+# Extract all WebSocket text payloads
+tshark -r your_capture.pcap -Y "websocket.payload.text" -T fields -e websocket.payload.text
+```
+
+---
+
+## Step 14 – Extracting from Internal App Logs (macOS)
+
+If you are using the macOS app and cannot decrypt the cloud traffic due to pinning, you can still extract the JSON/XML messages from the app's internal communication log.
+
+A helper script is provided in `scripts/extract-log-interactions.go`. It parses the interleaved "Native" and "Network" calls to reconstruct the application's internal state and cloud requests.
+
+```bash
+# Run extraction from the log file
+# Outputs a chronological record of internal events and network URLs
+go run scripts/extract-log-interactions.go path/to/log.txt > extracted-interactions.http
+```
+
+**What this shows:**
+- **TO NETWORK:** The URLs the app is about to call (intercepted before encryption).
+- **FROM NATIVE:** Data being returned from the OS or Cloud to the UI.
+- **TO NATIVE:** Commands being sent from the UI to the underlying engines.
+
+This is a powerful "Plan B" when HTTPS decryption is blocked, as the app essentially logs its own decrypted data for you.
+
+---
+
+## Helper Commands / Troubleshooting
+
+After a Pi reboot, everything should come up automatically. If not:
+
+```bash
+# Restart and enable all core services
+sudo systemctl restart systemd-networkd
+sudo systemctl enable --now hostapd
+sudo systemctl enable --now dnsmasq
+sudo systemctl restart nftables
+
+# Verify the unmanaged state of wlan0 (nmcli)
+sudo nmcli device set wlan0 managed no
+```
+
+---
+
+## What to Expect
+
+| Protocol             | Port       | Tool                     | Visibility                                     |
+|----------------------|------------|--------------------------|------------------------------------------------|
+| DNS (Standard)       | UDP 53     | tcpdump, dnsmasq log     | Full, plaintext                                |
+| HTTPS / REST         | TCP 443    | tcpdump (SNI), mitmproxy | SNI without decryption, content with mitmproxy |
+| WebSockets           | TCP 443/80 | Wireshark                | Frames decoded if TLS is broken                |
+| mDNS / ZeroConf      | UDP 5353   | tcpdump, tshark          | Full, plaintext                                |
+| SSDP / UPnP          | UDP 1900   | tcpdump                  | Full, plaintext                                |
+| SoundTouch local API | TCP 8090   | tcpdump                  | Full, plaintext (no TLS)                       |
+
+> **Expectation for Bose SoundTouch:** The app likely uses standard DNS (older app generation), REST/HTTPS for the pairing flow with the cloud, WebSockets for push events from the device, and mDNS for local device discovery. The local device API on port 8090 is HTTP without TLS – this traffic is always readable.
+
+---
+
+## Next Steps After Analysis
+
+1. Extract domains from DNS log and SNI → List of all Bose endpoints
+2. HTTP methods and paths from mitmproxy log → Reconstruct API structure
+3. Document auth flow (OAuth2? Proprietary? Token format?)
+4. Build a minimal mock server simulating the critical endpoints
+5. Testing: App against mock server → does pairing work offline?
+
+---
+
+## Appendix A – Generating a Custom CA Certificate
+
+If you don't have a custom DNS server with a CA yet, you can create one directly on the Pi. Alternatively, if you are already using the `soundtouch-service` from this repository, you can reuse its CA certificate located in the `data/certs/` directory.
+
+### 0. (Optional) Copy an Existing CA from another host
+
+If you are already using the `soundtouch-service` on another machine (e.g., your notebook), you can copy the existing CA to the Pi instead of generating a new one:
+
+```bash
+# On your Pi:
+sudo mkdir -p /etc/my-dns-ca
+sudo chown $USER:$USER /etc/my-dns-ca
+
+# Run this on your notebook (replace hostnames and paths):
+# Note: This is easiest if your SSH key is added to the Pi and soundtouch-service host.
+# If you run into permission issues with sudo, ensure the source user has passwordless sudo for 'cat'.
+
+# Step A: Download from source to your notebook
+ssh soundtouch-service "sudo cat /var/lib/soundtouch-service/certs/ca.crt" > ca.crt
+ssh soundtouch-service "sudo cat /var/lib/soundtouch-service/certs/ca.key" > ca.key
+
+# Step B: Upload from notebook to the Pi
+scp ca.crt ca.key soundtouch-access-point:/tmp/
+ssh soundtouch-access-point "sudo mv /tmp/ca.crt /tmp/ca.key /etc/my-dns-ca/ && sudo chown root:root /etc/my-dns-ca/ca.*"
+rm ca.crt ca.key
+```
+
+### 1. Create CA Key and Certificate
+
+```bash
+sudo mkdir -p /etc/my-dns-ca
+cd /etc/my-dns-ca
+
+# Generate CA private key
+sudo openssl genrsa -out ca.key 4096
+
+# Generate Root CA certificate
+# Note: we explicitly add basicConstraints=CA:TRUE for modern TLS clients
+sudo openssl req -x509 -new -nodes -key ca.key -sha256 -days 3650 \
+  -out ca.crt \
+  -subj "/C=DE/O=Bose-Lab/CN=Bose-Lab Root CA" \
+  -addext "basicConstraints=critical,CA:TRUE" \
+  -addext "keyUsage=critical,keyCertSign,cRLSign"
+```
+
+### 2. Generate a Certificate for Interception (Example)
+
+To intercept `global.api.bose.io`, you need a certificate for it, signed by your CA:
+
+```bash
+# Generate server key
+sudo openssl genrsa -out bose.key 2048
+
+# Create CSR (Certificate Signing Request) configuration
+sudo tee bose.ext << 'EOF'
+authorityKeyIdentifier=keyid,issuer
+basicConstraints=CA:FALSE
+keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
+subjectAltName = @alt_names
+
+[alt_names]
+DNS.1 = global.api.bose.io
+DNS.2 = *.bose.io
+EOF
+
+# Generate CSR
+sudo openssl req -new -key bose.key -out bose.csr \
+  -subj "/C=DE/O=Bose-Lab/CN=global.api.bose.io"
+
+# Sign the certificate with your CA
+sudo openssl x509 -req -in bose.csr -CA ca.crt -CAkey ca.key \
+  -CAcreateserial -out bose.crt -days 365 -sha256 -extfile bose.ext
+```
+
+### 3. Usage in your DNS/HTTPS Server
+
+Your custom server (e.g., a small Go or Python script) would then use `bose.crt` and `bose.key` to serve HTTPS traffic for those domains.
+
+## Appendix B – Helpful Commands
+
+```bash
+# Which IPs did the phone receive?
+cat /var/lib/misc/dnsmasq.leases
+
+# Is the access point active?
+sudo systemctl status hostapd
+
+# Is dnsmasq active?
+sudo systemctl status dnsmasq
+
+# Check interfaces and IPs
+ip addr show
+
+# Check routing table
+ip route show
+
+# Show active nftables rules
+sudo nft list ruleset
+
+# All running tcpdump processes
+pgrep -a tcpdump
+
+# Test the Pi's own DNS resolution
+dig @127.0.0.1 -p 5353 global.api.bose.io
+
+# Check network connectivity from the phone (from the Pi)
+ping 192.168.10.101   # Phone IP from dnsmasq.leases
+```

+# What a SoundTouch speaker does during factory reset
+
+Observed live on ST10 firmware `27.0.6.46330.5043500` (build `epdbuild.trunk.hepdswbld04.2022-08-04`) on 2026-05-12, by running `soundtouch-cli setup factory-reset` and tailing the speaker's `logread` over SSH. The trace is preserved at `_/logs/factory-reset.txt` for reference.
+
+## Sequence
+
+1. **Telnet receives `sys factorydefault`.** The diagnostic shell on port 17000 accepts the command and acknowledges. Some firmwares close the socket as part of the reboot — our CLI's `setup factory-reset` tolerates that as success.
+
+2. **Speaker DELETEs itself from its marge account.** Before wiping anything, the firmware does:
+   ```
+   [MargeStateAssociated] HandleRemoveDeviceRequest - Removing this device from the user's Marge account
+   [MargeClient]          RemoveDevice calling Marge Server with https://streaming.bose.com/streaming/account/{accountId}/device/{deviceId}
+   [MargeClient]          RemoveDeviceCB - Device removed from the user's Marge account
+   [MargeStateAssociated] HandleRemoveDeviceRequestSuccessCB, Marge returned: {"ok": true}
+   ```
+   AfterTouch already handles this — `HandleMargeRemoveDevice` (`pkg/service/handlers/handlers_marge.go:633`) routed via `r.Delete("/device/{device}", …)` in `cmd/soundtouch-service/main.go:955`. The handler calls `marge.RemoveDeviceFromAccount(s.ds, account, device)` and prunes the device from the datastore.
+
+3. **Speaker notifies its LAN peers.** Two HTTP POSTs to each known peer at `:8090/notification`:
+   ```
+   [NotificationSender] SendNotifyLisas_: URL: >>http://192.0.2.122:8090/notification<<, m_msgdata.size(58)
+   [SimpleURLFetcher]   multipart/form-data text/xml
+   ```
+   ~58 bytes of `multipart/form-data` carrying `text/xml`. "Lisas" is the firmware's internal term for LAN peers (devices on the same account on the same network segment). AfterTouch is **not** on this path — it's pure peer-to-peer over the LAN. Peers presumably refresh their account info as a result.
+
+4. **Local state teardown.** Bluetooth pairings cleared (`BTRemoteDeviceAccess::ClearPrevPairedList`), zone/group state torn down, all source proxies disconnected (`STSAccountProxy::Disconnect Requested` × many).
+
+5. **Persistence cleanup.** Logs, core dumps wiped (`FactoryDefault: Clearing the CoreDump and BoseLogs … rm -rf /mnt/nv/BoseLog/*`). Notably **NOT wiped**: `/mnt/nv/aftertouch.resolv.conf`, `/mnt/nv/rc.local`'s Aftertouch hook, and `/mnt/nv/BoseApp-Persistence/1/SystemConfigurationDB.xml`. The reset only touches log directories and account-specific persistence under the same `/mnt/nv/BoseApp-Persistence/1/` tree.
+
+6. **Reboot into setup mode.** Speaker drops Wi-Fi, comes back as its own AP `Bose SoundTouch XXXX` on 192.0.2.1.
+
+## Implications for migration ordering
+
+The DELETE in step 2 only reaches AfterTouch if the speaker's `margeURL` already points at AfterTouch *at the moment of reset*. A speaker still pointing at `streaming.bose.com` sends it into the void → AfterTouch keeps a stale `account/{id}/device/{id}` entry until someone manually prunes it.
+
+Therefore for a clean datastore lifecycle on an already-Bose-paired speaker:
+
+1. Migrate URLs first (`setup migrate --method=resolv` or `--method=telnet`).
+2. Reboot to apply.
+3. Factory reset.
+4. Re-provision.
+
+`soundtouch-cli setup plan --reset` currently runs factory-reset first (optimal for already-on-AfterTouch speakers); both `setup plan --reset` and `setup factory-reset` print a one-line note explaining the ordering tradeoff so users can pick the right sequence for their starting state.
+
+## Implications for AfterTouch behaviour
+
+- The DELETE handler is already correct; no changes needed.
+- AfterTouch is invisible to the LAN-peer notification step — that's just LAN HTTP between speakers.
+- If you build a "consolidate account" / "migrate fleet" feature later, the peer-notification channel is the propagation path the firmware uses internally; AfterTouch doesn't need to do anything analogous.
+- The persistence layer at `/mnt/nv/` is **factory-reset-resistant**. Our DNS-redirect migration (`setup migrate --method=resolv`) writes there specifically so AfterTouch routing survives a reset. This is intentional — the user can factory-reset a speaker freely without re-running migration.
+
+## Open questions
+
+- Are there other peer endpoints the firmware POSTs to besides `:8090/notification`? Worth checking on a 3-speaker LAN.
+- Does the `:8090/notification` payload format match the format used for play-as-notification audio pushes, or is it a distinct message shape? The "size(58)" byte count is too small for an audio URL but big enough for an XML envelope with an event type.
+
+If you want either of these answered, capture two synchronised `logread -f` streams from two LAN speakers while one is being reset.
+
+## Runbook — reset & re-provision an ST10 on AfterTouch
+
+End-to-end command sequence used during the 2026-05-12 bare-pairing experiment, recorded verbatim from the test session. Replace IPs, SSID, password, service URL, and account ID with your own. Two manual Wi-Fi switches happen between `factory-reset` and `wifi-push` (host joins the speaker's AP) and again between `wifi-push` and `wait-online` (host re-joins home Wi-Fi).

+
+# Manual: switch host back to home Wi-Fi.
+#   macOS: networksetup -setairportnetwork en0 "wifi-name" 'a.secure!password'
+
+# mDNS-poll for the speaker on the home network, matched by deviceID suffix
+# (which survives the reset since it's the MAC). Returns the new IP.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup wait-online --match=536A98
+
+
+# === 3. Clock, migrate, pair. From here on use the new IP wait-online reported. ===
+
+# Set the speaker's wall-clock. `clock set --time=now` fails on FW 27;
+# `clock now` is the working subcommand.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 clock now
+
+# Reboot to clear any half-initialized resolver / NTP state from the wifi-push flap.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup reboot
+
+# Apply DNS-redirect migration: routes *.bose.com to AfterTouch and installs its CA.
+# Idempotent; safe to re-run.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup migrate \
+  --service-url=https://soundtouch.fritz.box --method=resolv
+
+# Reboot again so the envswitch parallel-persistence layer and the resolv hook
+# both take effect on the next boot.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup reboot
+
+# Pair the device with an AfterTouch account — bare experiment variant.
+# Drop --mode=bare and add --name=… / --language=… for the full state-machine variant.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup pair \
+  --mode=bare --account=1111111 --service-url='https://soundtouch.fritz.box'
+
+
+# === 4. Verify. ===
+
+# Reboot to verify persistence survives.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup reboot
+
+# Snapshot the result. margeAccountUUID should still equal --account, and Sources
+# should list ~14 entries (TUNEIN, RADIO_BROWSER, LOCAL_INTERNET_RADIO,
+# SPOTIFY slots, AIRPLAY, etc.) materialized by the firmware.
+go run ./cmd/soundtouch-cli --host 192.0.2.123 setup inspect
+```
+
+Total wall-clock for the above on this hardware: roughly 5 minutes including the two manual Wi-Fi switches and three reboots.

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