docs: make docs the single source of truth for install/update/removal flows

Following user feedback (Lang, issue #432 thread) the docs guides now
contain all operational detail — installation, configuration, service
management, logs, updates, and removal — and the scripts READMEs become
thin pointers to the docs rather than the other way around.

RASPBERRY-PI.md: expanded to cover soundtouch-web alongside
soundtouch-service (install, config, port-conflict note, service
management, logs, update, removal, arch auto-detection, security).
scripts/raspberry-pi/README.md: trimmed to a quick-start with the two
one-liners plus a link to the docs guide.

EXTERNAL-HOST-WALKTHROUGH.md Step 7: replaces the vague "download from
Releases" note with the actual install-web.sh one-liner and a link to
RASPBERRY-PI.md#soundtouch-web; adds a non-Pi install option too.

ON-DEVICE-INSTALL-WALKTHROUGH.md: removed both back-references to
scripts/on-device-install/README.md; added self-contained sections for
Updating (with rollback tip), Service management, Logs, and Uninstalling
so the walkthrough is complete without leaving the docs.

+Draft a "News & Updates" blog post for AfterTouch covering recent git activity, then open a draft PR for review.
+
+## Step 1 — Determine lookback window
+
+Run:
+```
+git log --format="%ad" --date=short -- docs/content/blog/ | grep -v '_index' | head -1
+```
+
+If a date is returned, use it as SINCE.
+If the output is empty (no posts yet), compute SINCE = 30 days before today:
+- macOS: `date -v-30d +%Y-%m-%d`
+- Linux: `date -d '30 days ago' +%Y-%m-%d`
+
+## Step 2 — Collect commits since SINCE
+
+Run:
+```
+git log --format="%ad %h %s" --date=short --since="$SINCE" --no-merges
+```
+
+Exclude these (they are noise):
+- Subjects matching: `^(ci|chore|deps|bump|Bump|test|lint|style|code style|debug)`
+- Dependabot bumps (subject contains "bump" and includes a package name pattern)
+- Routine doc link/URL fixes
+
+Group the remaining commits into categories:
+- **NEW FEATURES** — subjects starting with `feat(` or `feat:`
+- **BUG FIXES** — subjects starting with `fix(` or `fix:`
+- **SECURITY** — subjects starting with `sec` or containing "security", "inject", "path expression"
+- **DOCS** — user-visible doc changes only (new guides, major restructures)
+- **MAINTENANCE** — everything else that passed the filter
+
+Omit empty categories entirely.
+
+## Step 3 — Current version
+
+Run: `git tag --sort=-version:refname | head -1`
+
+## Step 4 — Determine the period label
+
+Use the first and last commit dates from Step 2 to produce a human-readable label,
+e.g. "May 2026" or "April – May 2026".
+
+## Step 5 — Write the blog post
+
+Create the file at: `docs/content/blog/YYYY-MM-slug.md`
+- YYYY-MM = today's year-month
+- slug = short kebab-case summary of the biggest theme
+
+Use this exact frontmatter shape:
+```yaml
+---
+title: "AfterTouch PERIOD: <one-line theme>"
+date: YYYY-MM-DD
+description: "<one sentence, ≤200 chars, suitable as a standalone teaser>"
+tags:
+  - <up to 4 tags from: security, tls, discovery, docs, cli, web, spotify, amazon, health, migration, fixes, ci>
+sidebar:
+  exclude: true
+---
+```
+
+Body structure:
+1. Opening paragraph (3–5 sentences) explaining what happened and why it matters to someone running AfterTouch.
+2. One `##` section per non-empty category. Use bullet points written for an operator audience — no raw git subjects, no internal Go package paths.
+3. End with: `**Current release:** vX.Y.Z`
+
+Target length: 300–600 words. Never include real IPs, MAC addresses, account IDs, or device names.
+
+## Step 6 — Create a branch and open a draft PR
+
+```bash
+git checkout -b blog/YYYY-MM-update
+git add docs/content/blog/YYYY-MM-slug.md
+git commit -m "docs(blog): add PERIOD update post"
+git push -u origin blog/YYYY-MM-update
+gh pr create --draft \
+  --title "Blog: PERIOD update post" \
+  --body "Automated draft from /blog-update skill. Review content before merging — deployment is automatic on merge to main."
+```
+
+If the `documentation` label exists on the repo, add `--label documentation`.
+
+## Step 7 — Done
+
+Report the PR URL. Do not merge, approve, or request review.

+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`).
+
+**Force-flags also require explicit approval.** `git add -f` (force-add
+a gitignored file), `git push --force`, `git push --force-with-lease`,
+and any other flag that overrides a git safety mechanism must be
+proposed and confirmed before running, for the same reason: they
+bypass protections that exist intentionally.
+
+## 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
+with, endorsed by, or authorised by Bose.
+
+## 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 shut down SoundTouch cloud services on **May 6, 2026**. Presets, music service browsing, and stereo pairing no longer work through Bose's infrastructure. AfterTouch restores all of these — no Bose infrastructure required.
 
-## Quick Start
+See the [Survival Guide](https://gesellix.github.io/Bose-SoundTouch/docs/guides/SURVIVAL-GUIDE/) for the full picture.
 
-### Installation
+[![AfterTouch docs homepage](media/docs-homepage.png)](https://gesellix.github.io/Bose-SoundTouch/)
+
+---
+
+## 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.
+
+Not sure which approach fits your situation? See the [Deployment Overview](./docs/content/docs/guides/DEPLOYMENT-OVERVIEW.md) — it compares running AfterTouch on a Raspberry Pi or other always-on host against running it directly on the SoundTouch speaker, with links to step-by-step walkthroughs for each path.
+
+**Getting started:**
+
+**Already migrated before May 6** — your presets and credentials are preserved. AfterTouch picks up where the Bose cloud left off.
+
+**Starting fresh (or after a factory reset)** — create a local account, configure your speakers, and start using them immediately.
+
+**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/docs/guides/DEVICE-INITIAL-SETUP/) and [Migration Guide](https://gesellix.github.io/Bose-SoundTouch/docs/guides/MIGRATION-GUIDE/) 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/docs/guides/CLI-REFERENCE/) 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.

+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
+```

+### 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

+soundtouch-backup local --ssh
+
+# Longer discovery window on busy networks
+soundtouch-backup local --discover-timeout 10s

+
+**What gets fetched via HTTP**
+
+| File                | Device endpoint |
+|---------------------|-----------------|
+| `info.xml`          | `/info`         |
+| `name.xml`          | `/name`         |

+| `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/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.
+
+---
+

+
+Both subcommands write into a single dated archive:

+
+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

-# Parity Analysis: Bose-SoundTouch (Go) vs. SoundCork (Python)
-
-This document provides a comparative analysis of the current Go implementation and the `deborahgu/soundcork` project, identifying functional gaps and potential improvements.
-
-## 1. Core Architecture and Language
-- **Bose-SoundTouch (Go)**: Uses `chi` for routing and `encoding/xml` for data. High performance, strong typing, and precise MIME type handling (`application/vnd.bose.streaming-v1.2+xml`).
-- **SoundCork (Python)**: Uses `FastAPI` and `xml.etree.ElementTree`. Prioritizes flexibility and rapid prototyping of streaming service mocks.
-
-## 2. Functional Comparison
-
-| Feature              | Bose-SoundTouch (Go)                             | SoundCork (Python)                                                                      |
-|:---------------------|:-------------------------------------------------|:----------------------------------------------------------------------------------------|
-| **Group Management** | Placeholder handlers (return `<group/>` or 404). | Active group management (`groups.py`), supporting `/addGroup` and stereo pairing logic. |
-| **BMX Services**     | Supports TuneIn, Orion, and custom streams.      | More modular `bmx_services.json` registry with broader mock support.                    |
-| **Persistence**      | Mixed JSON/XML datastore.                        | Pure XML-based persistence per device/account.                                          |
-| **Admin UI**         | CLI-based (`soundtouch-cli`) or API-driven.      | Draft Web UI for device discovery and account management (`admin.py`).                  |
-| **Discovery**        | Integrated setup tools and SSDP/MDNS awareness.  | Leverages `bosesoundtouchapi` Python library for active discovery.                      |
-
-## 3. Key Strengths of SoundCork
-- **Group Pairing Logic**: Includes logic to manage master/slave relationships for SoundTouch 10 stereo pairs.
-- **Service Extensibility**: JSON-based registry for BMX services makes it easier to mock multiple providers (SiriusXM, Spotify) without code changes.
-- **Mock Coverage**: Better coverage of "dummy" endpoints that respond with plausible XML (e.g., `customerSupport`).
-
-## 4. Suggested Implementation Steps for Bose-SoundTouch
-
-### A. Implement Full Group Support (High Priority)
-- Add logic to `pkg/service/marge` to handle `/addGroup` and `/updateGroup`.
-- Persist group memberships in the datastore to allow speakers to function as stereo pairs or multi-room zones.
-
-### B. 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.
-
-### C. 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`.
-
-### D. 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
-While our Go implementation is structurally more consistent with recent reference recordings (e.g., `buttonNumber`, detailed `components`), SoundCork provides better coverage of multi-device coordination (Groups) and service emulation (BMX) that we should adopt for a more complete offline experience.

-client.AddZoneSlave("MASTER123", "SLAVE456", "192.168.1.101")
-client.RemoveZoneSlave("MASTER123", "SLAVE456", "192.168.1.101")
-```
-
-**Enhanced High-Level API:**
-```go
-// High-level fluent API (enhanced implementation)
-zone := client.CreateZoneWithIPs("192.168.1.100", []string{"192.168.1.101", "192.168.1.102"})
-client.AddToZone("192.168.1.100", "192.168.1.103")
-client.RemoveFromZone("192.168.1.100", "192.168.1.101")
-client.DissolveZone("192.168.1.100")
-```

-### Medium Impact: None ✅
-All common use cases are covered.
-
-### Low Impact: 1 Non-functional Feature ❌
-
-#### 1. Non-functional Endpoint
-- **Official**: `/trackInfo`
-- **Impact**: None - identical functionality available via `/now_playing`
-- **Issue**: Times out on real devices despite being documented in API
-- **Workaround**: Use `GetNowPlaying()` method instead
-
----
-
-## Testing Coverage
-
-### Endpoint Testing: 100%
-- ✅ All implemented endpoints have comprehensive unit tests
-- ✅ Real device integration testing completed
-- ✅ Error handling and edge cases covered
-- ✅ WebSocket event system fully tested
-
-### Test Statistics:
-```
-Unit Tests:        200+ test cases
-Integration Tests: Real device validation
-Benchmark Tests:   Performance validation
-Coverage:          >90% code coverage
-```
-
----
-
-## Recommendations
-
-### For Standard Users: ✅ **Complete**
-This implementation provides **everything needed** for standard SoundTouch usage:
-- Media control, volume management, source selection
-- Preset access, device information, real-time updates
-- Multiroom zone management, device discovery
-
-### For Advanced Users: ✅ **Excellent**
-Additional features beyond standard API:
-- Enhanced safety controls, comprehensive event system
-- Extended device information, network management
-- Superior zone management implementation
-
-### For Professional Installations: ⚠️ **Mostly Complete**
-Missing only niche professional features:
-- Advanced DSP audio controls
-- Professional tone/level controls
-- Individual zone slave micro-management
-
-**Recommendation**: For 99% of use cases, this implementation is **complete and superior** to a basic API implementation.
-
----
-
-## Future Considerations
-
-### Potential Additions (Low Priority):
-1. **Extended WebSocket Events** - Additional real-time notifications if discovered
-2. **API Evolution Support** - Monitor for new official API versions beyond v1.0
-
-### API Evolution:
-- Monitor for new official API versions beyond v1.0
-- Test extended features with new device models
-- Consider community feedback for additional functionality
-
----
-
-## Conclusion
-
-This implementation achieves **complete API coverage** with:
-- ✅ **95% functional endpoint implementation** (20/21)
-- ✅ **100% official API endpoint implementation** (21/21)
-- ✅ **100% essential functionality coverage**
-- ✅ **Superior implementations** for complex operations
-- ✅ **Extended features** beyond official specification
-- ✅ **Complete advanced audio controls** for professional devices
-- ✅ **Complete notification system** (TTS, URL playback, beep notifications)
-- ✅ **Comprehensive testing and validation**
-
-The single non-functional endpoint (`/trackInfo`) is **broken on real devices** despite being documented in the official API, but identical functionality is available via `/now_playing`. The implementation **exceeds the official API** in many areas through enhanced safety features, complete zone management, advanced audio controls, and real-time event capabilities.
-
-**Note**: All official API endpoints are implemented. The `/trackInfo` endpoint times out on real devices but is implemented and tested.
-
-**Overall Assessment: Complete** ⭐⭐⭐⭐⭐

+description: "Bose shut down SoundTouch cloud services in May 2026. AfterTouch replaces everything your speakers relied on — migration, radio, Spotify, presets, and more."
+tags:
+  - migration

+  - spotify

+  exclude: true
+---
+
+On May 6, 2026, Bose shut down the SoundTouch cloud services that millions of speakers
+depended on for account sync, presets, internet radio, and streaming. Speakers kept
+working locally, but remote features stopped and first-time setup became impossible.
+
+AfterTouch was built to change that. It is a self-hosted replacement for the Bose
+cloud infrastructure — a drop-in local service that your speakers talk to instead of
+`streaming.bose.com`. This post covers what works today and how to get started.
+
+## What works right now
+
+### Migration and first-time setup
+
+If your speaker was registered with Bose before the shutdown, AfterTouch can **migrate
+your existing account and presets** in a single step — no reconfiguration on the
+speaker side. If you are setting up a factory-reset or brand-new speaker, AfterTouch
+handles that path too, guiding you through Wi-Fi pairing and account creation locally.
+See the [Migration Guide](../docs/guides/MIGRATION-GUIDE.md) for step-by-step instructions.
+
+### Internet radio — TuneIn and RadioBrowser
+
+Both **TuneIn** and **RadioBrowser** are fully supported for browsing and playback.
+Navigate categories and search for stations exactly as you did with the original Bose
+app. TuneIn delivers the same station catalogue; RadioBrowser provides an open,
+community-maintained alternative.
+
+### Spotify
+
+**Spotify** works via both OAuth (account linking) and Spotify Connect (the ZeroConf
+"connect to device" flow from the Spotify app). Once linked, playback and device
+selection behave the same as before.
+
+### Presets
+
+Your six preset buttons work. AfterTouch stores preset bindings locally and serves them
+back to the speaker on request. You can also **save new presets** — via the API,
+via `soundtouch-cli`, or through the soundtouch-web UI.
+
+### ST-10 stereo pairing
+
+**SoundTouch 10 stereo pairs** (and other ST pairing configurations) are supported
+end-to-end: creation, management, and playback routing all go through AfterTouch.
+
+### soundtouch-web — browser UI
+
+**soundtouch-web** is an early-stage but functional browser UI bundled with AfterTouch.
+It gives you:
+
+- TuneIn and RadioBrowser browsing and playback
+- Speaker management and device discovery
+- Recent tracks panel
+- Multi-room zone management
+
+It runs as part of the AfterTouch service — no separate install needed.
+
+![soundtouch-web UI showing Spotify playback, presets, sources, and zone management](/images/blog/soundtouch-web-ui.png)
+
+### Automation with soundtouch-cli
+
+The **`soundtouch-cli`** command-line tool covers every speaker control: play, pause,
+volume, source selection, preset recall, group management, migration, and more.
+It is well-suited for home-automation scripts, cron jobs, and shell one-liners.
+
+## Three ways to install
+
+AfterTouch runs on any machine your speakers can reach:
+
+1. **On the speaker itself** — install directly on supported SoundTouch hardware via
+   the on-device installer. The speaker hosts its own replacement cloud, with no
+   additional hardware required.
+
+2. **On a local network host** — run AfterTouch on any machine on your LAN. A
+   **Raspberry Pi Zero 2W** handles the load without breaking a sweat, making this
+   path remarkably low-cost and low-power.
+
+3. **On a cloud or VPS host** — deploy to a remote server for access outside your
+   home network. AfterTouch handles TLS certificate generation and DNS configuration
+   for this scenario.
+
+All three paths are documented in the [Deployment Overview](../docs/guides/DEPLOYMENT-OVERVIEW.md).
+
+## Current release
+
+**v0.93.1** — released May 24, 2026
+
+## Community
+
+AfterTouch would not be where it is without the people who opened issues, tested
+pre-release builds, reported edge cases, and contributed code. A significant share of
+the fixes and features shipped in the lead-up to the cloud shutdown were driven by
+real-world feedback from the community — from migration quirks to stereo-pair
+specifics to Spotify Connect timing issues. Thank you to everyone who helped.
+
+If you run into something or have an idea, the
+[GitHub issue tracker](https://github.com/gesellix/Bose-SoundTouch/issues) and
+[Discussions](https://github.com/gesellix/Bose-SoundTouch/discussions) are the
+right places to start.
+
+## What's next
+
+The soundtouch-web UI will gain richer preset management — browsing, editing, and
+reordering presets directly from the browser. Longer term, merging
+`soundtouch-service` and `soundtouch-web` into a single binary is on the table,
+which would simplify deployment to a single process with no extra flags.
+
+This blog will be updated monthly — or whenever something significant ships.

+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.
+
+`AA:BB:CC:DD:EE:FF` is the conventional "locally administered" MAC
+placeholder used in many vendor docs.
+
+`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.
+
+## Why we don't use 192.168.1.x
+
+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.
+
+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`.
+
+## How to audit before committing
+
+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.
+
+Some patterns flag clearly-non-placeholder values:
+
+```sh
+# Any IPv4 not in a documentation range or the 192.168.1.x default:
+git ls-files | xargs grep -hoE "[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+" 2>/dev/null \
+  | grep -vE "^(192\.0\.2\.|198\.51\.100\.|203\.0\.113\.|0\.0\.0\.0|127\.0\.0\.1|255\.255\.255\.255|192\.168\.1\.[0-9])" \
+  | sort -u
+
+# Any colon-separated MAC that doesn't start with AA:BB:CC:DD:EE:
+git ls-files | xargs grep -hoE "[0-9A-F]{2}(:[0-9A-F]{2}){5}" 2>/dev/null \
+  | grep -vE "^AA:BB:CC:DD:EE:" \
+  | sort -u
+```
+
+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.
