feat(soundtouch-web): add multi-room zone management

Backend:
- GET /api/zone/{id} — zone info enriched with device names and role flags
- POST /api/zone/{id}/add/{slaveId} — add slave (creates zone if standalone)
- POST /api/zone/{id}/remove/{slaveId} — remove slave from zone
- POST /api/zone/{id}/dissolve — dissolve zone to standalone
- POST /api/zone/{id}/leave — slave leaves its zone (backend finds master)

Frontend (Zone.js):
- Standalone: shows "Group with…" button, opens device picker overlay
- Master: member list with per-row Remove, Add speaker, Dissolve buttons
- Slave: shows master name, Leave zone button
- Lazy-loads on device detail open; refreshes after each zone operation

-If you want to run a server for this - no problem. The service is small enough to run on the SoundTouch itself. See the [On-Device Installer](./scripts/on-device-install/README.md) for instructions.

 To enable offline operation or use custom services like **SoundCork** or **ÜberBöse API**, SoundTouch devices must be redirected from Bose's official cloud endpoints to a local or custom server. This document outlines the three known methods to achieve this, gathered from community reverse-engineering efforts in the **SoundCork** and **ÜberBöse API** projects.
 
-> A fourth, **SSH-free** path — driving the device's diagnostic shell on TCP port 17000 — is being added as a peer to the XML and DNS methods. See **[TELNET-MIGRATION-METHOD.md](TELNET-MIGRATION-METHOD.md)** for the use cases, community findings, and feasibility analysis. The `/etc/hosts` method documented below is now deprecated and will not be exposed in the web UI.

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

-The S4 `bose` script's `sys presetkey N p` form still works, but `key prefix_N` is shorter and matches what the remote already does on FW 27.x.

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

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

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

-These show up in `getpdo`, `network status`, and SSH-side hostnames. Useful for matching captures to hardware.

-## Firmware era notes
-
-- **Firmware 1.x–7.x** (S1 era): everything — `help`, `remote_services on`, full `scm`, and an in-shell login prompt. `flarn2006` documents the original Linux insides.
-- **Firmware 8.x–14.x** (S2 era): `remote_services on` removed; `network`, `sys`, `envswitch`, `getpdo` still present. `local_services on` works on some Wave/SA-5 models.
-- **Firmware 27.x** (S5/S6 era — the long-lived "frozen" build that survived through EOS): `help`, `remote_services on`, and `sys ver` removed in some builds; `sys configuration …` and `envswitch …` confirmed working on ST 10, ST 20, ST 300, Wave III, Wave IV. **This is the firmware our migration targets**. The Portable on more recent firmware drops further commands and is the hardest target.
-
-  S5 enumerated the **top-level command roots** that don't return "Command not found" on a vanilla ST 10 (`rhino`) running `27.0.6.46330.5043500`:
-
-  ```
-  key
-  net
-  sys
-  getpdo
-  ```
-
-  Notably absent from that probe: `network`, `envswitch`, `scm`, `ws`, `swupdate`, `remote_services`, `local_services`, `demo`, `mode`, `help`. **However**, other captures on the same firmware family (S6, ST 20 / Wave III / Wave IV) accept `envswitch …`, suggesting either per-model variation in the shipped command table or an SSH/role gate the S5 author didn't trip. Implementations that use `envswitch` should treat its absence as a recoverable preflight outcome (we already do).
-
-  `net` is observed as a valid root by S5 but its sub-commands aren't enumerated; it may be a shorthand alias for `network` on FW 27.x ST 10.

-sys configuration margeServerUrl <serverURL>
-sys configuration swUpdateUrl    <serverURL>/updates/soundtouch
-envswitch boseurls set <serverURL> <serverURL>/updates/soundtouch
-getpdo CurrentSystemConfiguration
-```
-
-Plus, when pairing a fresh device whose `:8090/setMargeAccount` is missing or wedged, the helper falls back to:
-
-```
-envswitch accountid set <7-digit-id>
-```
-
-Reboot is **not** part of these sequences — it stays a user-initiated action via the existing reboot button, which now accepts `?method=telnet|ssh` and sends `sys reboot` when telnet is picked.

-## Out of scope here, but worth recording
-
-- **Setup-mode WiFi onboarding via 192.0.2.1.** The community uses this to add a fresh device to a network without the Bose app. Our `soundtouch-service` does not currently automate this, but `network wifi profiles add` is the entry point if we ever do.
-- **Direct preset / playback control via `sys`.** The S4 `bose` script demonstrates a viable headless remote-control path that does not need our marge emulation at all. Useful as a fallback for tooling on devices that refuse to talk to any cloud.
-- **`scm restart <service>`.** Not used today, but a possible recovery primitive on older firmware where a stuck service blocks streaming.

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

-## 1. Why a third method is needed
-
-The two currently shipped methods both have hard preconditions that block real
-users:
-
-| Method                                  | Preconditions                                                | Failure modes seen in the wild                                                                                                                                                         |
-|-----------------------------------------|--------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| **XML** (`SoundTouchSdkPrivateCfg.xml`) | SSH/root access — needs `remote_services` USB unlock first   | Some firmware revisions (e.g. SA-5, ST520, latest ST Portable) refuse the USB unlock entirely; `remote_services on` was removed from the telnet command set in firmware 7.x and later. |
-| **DNS** (`resolv.conf` priority hook)   | SSH/root access; service must own port 53 on the LAN gateway | Won't fit users behind ISP routers they can't reconfigure; still requires the device to be SSH-reachable to write the hook.                                                            |
-
-The community has demonstrated a **third path that needs no SSH at all**:
-the device's built-in **diagnostic Telnet shell on TCP port 17000** accepts
-configuration commands that change exactly the same fields the XML method would.
-
-### 1.1 Confirmed user reports (firmware 27.0.6.46330.5043500 unless noted)
-
-| Reporter           | Hardware                  | Outcome                                                                                                     |
-|--------------------|---------------------------|-------------------------------------------------------------------------------------------------------------|
-| `foob61451` (#221) | ST 10, ST 20 (non-rooted) | All four URLs persisted via `sys configuration …`; `envswitch boseurls set …` survived `sys reboot`.        |
-| `bveenker` (#221)  | Wave III                  | URLs accepted; presets work after pairing via `/setMargeAccount` (see §3).                                  |
-| `stephan48` (#221) | Wave IV                   | Telnet:1700 + USB stick `remote_services` did **not** work; **port 17000 telnet** worked for all four URLs. |
-| `mcdona1d` (#141)  | ST 20, ST 300             | Confirmed working with `sys configuration …` + `envswitch …` + `sys reboot`.                                |
-| `TJGigs` (#228)    | ST 20 ×2, ST 10           | Wraps telnet:17000 into an admin "Smart Inject" tool; uses `sys reboot` over telnet to nudge devices.       |
-
-So the method is plausible across **at least ST 10/20/300 and Wave III/IV** on
-the most common firmware that survived the EOS cut, **without the USB unlock
-dance** that newer firmware refuses.

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

-> **See §9 for the as-shipped state.** Section 7 below records the
-> original forecast; the wizard grew larger during implementation and
-> §9 documents what actually landed.
-
-## 7. Summary of what changes when this lands
-
-- **New reusable package `pkg/telnet`** — sibling of `pkg/ssh`, line-oriented
-  TCP client with `Dial`, `SendCommand`, `Probe`, `Close`, all deadline-driven.
-  No external dependencies, usable from CLI, service, and tests.
-- **New `MigrationMethodTelnet = "telnet"`** constant in `pkg/service/setup/setup.go`
-  plus a `migrateViaTelnet` branch in `Manager.MigrateSpeaker`.
-- **New `pkg/service/setup/telnet_migration.go`** orchestrating the URL
-  configuration sequence (§2.1) on top of `pkg/telnet`. Configuration only —
-  no `sys reboot` here.
-- **New `pkg/service/setup/marge_pairing.go`** with `PairAccount(deviceIP, id)`:
-  probes `/supportedURLs`, time-bounded `POST /setMargeAccount`, falls back to
-  telnet `envswitch accountid set <id>` on missing/wedged endpoint.
-- **`Manager.Reboot` and `HandleRebootDevice` gain a method selector** —
-  signature changes to `Reboot(deviceIP string, method RebootMethod) (string, error)`
-  with `RebootMethodSSH` (default, today's behavior) and `RebootMethodTelnet`
-  (sends `sys reboot` over a fresh `pkg/telnet` connection). Handler reads
-  `?method=ssh|telnet` from the query string.
-- **`MigrationSummary` gains** `TelnetReachable`, `TelnetBanner`,
-  `TelnetCommandsAccepted`, `SetMargeAccountSupported`, `CurrentAccountID`,
-  `KnownAccountIDs` so the UI can show preflight outcomes and offer reuse.
-- **UI** — `web/index.html` dropdown gets a `telnet` option (greyed out when
-  preflight fails) and a new pane for picking/entering/randomizing a 7-digit
-  account ID when `:8090/info` reports an empty `margeAccountUUID`. The
-  existing reboot button gets a method selector (radio or dropdown) wired to
-  the new query param, with `confirm()` before firing. The legacy `hosts`
-  option stays out of the dropdown (deprecated).

-## 8. Device compatibility today
-
-What follows is the current best read on which devices our `migrateViaTelnet`
-flow handles end-to-end, derived from the same six sources catalogued in
-[TELNET-COMMAND-REFERENCE.md](TELNET-COMMAND-REFERENCE.md) plus the issue
-threads cited above. This is migration-outcome perspective; for per-command
-availability see the reference doc.
-
-### 8.1 Proven to work end-to-end
-
-All on the firmware-27.0.6 family, which is what survived through Bose's
-end-of-service cut. Multi-reporter agreement on every row.

-The exact sequence each reporter ran by hand is the sequence our migration
-sends (§2.1). So the migration's happy path is exercised against five
-hardware variants in independent captures.
-
-### 8.2 Proven to need the pairing fallback
-
-Migration of the URLs themselves works on these models, but
-`POST /setMargeAccount` is missing or wedged on the firmware build, so
-pairing has to go through the telnet `envswitch accountid set <id>` path
-that `setup.PairAccount` already implements.
-
-| Device                         | Reporter | Source                      | Why fallback is needed                                                                                                                                   |

-| ST Portable / FW 27.0.6        | jmosen   | #236                        | After migration: `POST /marge/streaming/support/power_on` → 502; `<margeAccountUUID/>` empty. Time-bounded HTTP path fails; envswitch fallback succeeds. |
-| BST20 Portable (factory reset) | ubittner | scheilch/opencloudtouch#167 | `<margeAccountUUID/>` empty; `/setMargeAccount` not in `/supportedURLs`. HTTP path skipped entirely; only the telnet fallback works.                     |
-
-### 8.3 Likely to fail (but the failure is clean)
-
-Our preflight + abort-on-first-rejection design (`TestMigrateViaTelnet_CommandNotFoundAborts`)
-means none of these scenarios leave a device half-configured. The user is
-told what failed and pointed to the XML or DNS method.
-

-| **SA-5** (sound amplifier) on FW 9.0.43.x  | soundcork#141   | FW 9.x has a different shell generation: `->` prompt, `local_services on`, `scm uboot_ver`. **`sys configuration` and `envswitch` are not documented as working there.** Migration fails on command #1.                                  |
-| **Recent ST Portable** (post-27.0.6.46330) | #236 (indirect) | `/setMargeAccount` removal points to broader command-set shrinkage.

-
-### 8.5 The S5 "valid roots" tension
-
-S5 (the r/bose telnet-probing thread) lists only `key`, `net`, `sys`,
-`getpdo` as command roots that don't return "Command not found" on its
-ST 10 / FW 27.0.6 — which would seem to rule out `envswitch`. But foob61451
-on the same hardware/firmware ran `envswitch boseurls set` successfully
-(#221).
-
-The most plausible reading is that **S5 is a non-exhaustive probe**, not a
-negative claim: the author writes "I've made some educated guesses and come
-up with the following valid commands" and never says they tested
-`envswitch`. We do not down-weight `envswitch` availability on the strength
-of S5 alone — but if a real-device run ever shows `envswitch` rejected on
-an ST 10, our preflight catches it, the migration aborts on the first
-non-OK response, and the user gets a clear error rather than partial state.
-
-### 8.6 Failure-mode matrix
-
-What `migrateViaTelnet` does in each failure mode (verified by
-`pkg/telnet` and `pkg/service/setup` unit tests):
-
-| Failure                                        | Outcome                                                                                           | Test                                                                                                               |

-### 8.7 TL;DR
-
-- **Green light** — ST 10, ST 20, ST 300, Wave III, Wave IV on FW 27.0.6 (multi-reporter agreement).
-- **Yellow** — ST Portable and BST20 Portable: migration works, pairing needs our fallback (already implemented).
-- **Red, but fails cleanly** — SA-5 on FW 9.x, possibly newer ST Portable builds.
-- **Unverified but expected to work** — ST 30, ST 520, Wave Music System I/II.
-
-The most useful next verification step is touching a real ST 30 and ST 520
-— those are the two "expected to work" models with zero concrete captures.
-Beyond that, every behaviour the doc predicts is exercised by the unit
-tests in `pkg/telnet` and `pkg/service/setup`.
-
----
-
-## 9. What actually shipped (post-implementation addendum)
-
-§7 forecast the surface area roughly; the wizard ended up larger. This
-section is the present-day map of the migration tab and the supporting
-backend pieces — kept appended rather than rewritten in place so the
-feasibility analysis above stays a faithful design record.
-
-### 9.1 Three-axis state model
-
-`MigrationSummary` now exposes the four mechanism-specific booleans
-that `checkIsMigrated` writes individually:
-
-- `XMLMigrated` — parsed SoundTouchSdkPrivateCfg.xml's URLs point at us.
-- `HostsMigrated` — `/etc/hosts` carries Bose-domain redirects (the
-  deprecated method, kept detectable for legacy speakers).
-- `ResolvMigrated` — the `/etc/resolv.conf` priority-nameserver hook
-  is in place (with CA trusted).
-- `TelnetMigrated` — `getpdo CurrentSystemConfiguration` reports the
-  service hostname.
-
-`IsMigrated` is the OR. Plus `IsPaired` from the live
-`:8090/info.margeAccountUUID` value.
-
-The frontend opens with a state card that surfaces three orthogonal
-axes derived from these flags:
-
-| Axis              | Verdict semantics                                                                                                     |
-|-------------------|-----------------------------------------------------------------------------------------------------------------------|
-| URL Configuration | URL flip active → ✅; original Bose URLs + DNS hook active → ✅ (intercepted); original + no DNS → ❌ (not intercepted). |
-| DNS Interception  | None / resolv.conf hook / /etc/hosts (with deprecated badge).                                                         |
-| CA / TLS          | Local root CA installed yes/no.                                                                                       |
-
-Plus a Preconditions row: `remote_services` persistence, account
-pairing state, XML config backup presence. Action affordances
-(`Trust CA Now`, `Download CA cert`) live inline next to their verdicts.
-
-### 9.2 Plan card with per-field URL editor
-
-Replaces the XML method's `self/proxied/original` dropdowns and the
-duplicate URL inputs that used to live inside the telnet method pane:
-
-- Target service URL input with `Save as default` (POSTs to
-  `/setup/settings`, preserving the `***` secret-unchanged convention).
-- Capabilities header: detected transports (SSH / Telnet:17000) and
-  the recipes AfterTouch can offer given those transports.
-- Service URLs table: four free-form URL inputs (Marge / Stats /
-  SwUpdate / BmxRegistry) with on-keystroke validation
-  (`validatePlanURLs`), a Soundcork-mode checkbox that flips `/marge`
-  on `margeServerUrl`, and a `Reset to defaults` button.
-- Account pairing section: ID input + Generate + datastore picker;
-  the implicit intent (`readPlanPairTarget`) queues a pair step at
-  Apply when the input differs from the current `account_id`.
-- Suggested plan box: one-click conservative default — XML + HTTP
-  when SSH works, Telnet + HTTP otherwise; "Already migrated" info
-  state when `IsMigrated` is already true.
-
-The per-field URLs feed both XML and Telnet migrations via the
-`marge_url` / `stats_url` / `sw_update_url` / `bmx_url` option family
-(see §9.6). Live preview rewrites `#planned-config` purely client-side
-on every keystroke — optimistic; the backend's perspective gates the
-write via §9.4's pre-flight.
-
-### 9.3 Customize three-axis form
-
-The `<details>` "Customize this migration" section replaces the old
-migration-method dropdown with three independent radio groups:
-
-1. **URL flip transport**: XML / Telnet:17000 / Skip.
-2. **DNS interception**: None / `/etc/resolv.conf` hook.
-3. **Local CA install**: checkbox.
-
-Each option carries a per-axis availability hint
-(`(SSH unreachable)`, `(already trusted)`, etc.) so users see *why*
-an option is disabled. `applyCustomPlan` orchestrates the chosen
-combination as a sequence of existing backend calls
-(`/setup/migrate?method=…` for each flip/resolv step plus
-`/setup/trust-ca` for standalone CA install, and the queued pair
-step from §9.2). Resolv already bundles a CA install, so a redundant
-standalone CA step is skipped. First failure aborts the rest.
-
-### 9.4 Pre-flight panel
-
-Both Apply paths run a visible pre-flight panel before any backend
-operation touches the speaker. Each check renders inline with the
-🕐 / ⟳ / ✅ / ❌ / — idiom. On all-green the panel holds for ~700ms so
-the success state registers, then auto-proceeds. On any failure the
-panel surfaces `Proceed Anyway` / `Cancel` buttons; default is to
-abort.
-
-Checks:
-
-| Check                         | When                                          | Backend route                  |
-|-------------------------------|-----------------------------------------------|--------------------------------|
-| Backend summary re-check      | always                                        | `GET /setup/summary`           |
-| HTTPS connection from device  | `ssh_success && server_https_url`             | `POST /setup/test-connection`  |
-| Telnet round-trip probe       | `!ssh_success && telnet_reachable` (see §9.5) | `POST /setup/telnet-probe`     |
-| DNS redirection from device   | `methods.includes("resolv") && ssh_success`   | `POST /setup/test-dns`         |
-
-The HTTPS check uses `use_explicit_ca=true` so it exercises the trust
-path even when CA install is part of the plan (i.e. forward-looking).
-The reachability skip row is explicit ("neither SSH nor Telnet:17000
-is reachable") rather than silently dropped, per the user's
-"feedback always visible" requirement.
-
-### 9.5 Telnet round-trip probe — the SSH-less reachability check
-
-The reachability gap §7 left open for USB-unlock-refusing speakers is
-closed by `Manager.RunTelnetRoundTripProbe`
-(`pkg/service/setup/telnet_probe.go`). Sequence:
-
-1. Telnet `getpdo CurrentSystemConfiguration` to capture the
-   speaker's current `swUpdateUrl`.
-2. Generate a random 24-hex-char token; register a one-shot signal
-   channel under it on the new `probeRegistry` (sibling field on
-   `handlers.Server`).
-3. Telnet `sys configuration swUpdateUrl <targetURL>/probe/<token>`
-   — **runtime layer only, deliberately not `envswitch boseurls set
-   …`**. The persistence layer keeps the original URL, so a reboot
-   heals the device naturally if our restore step fails.
-4. `HTTP GET <deviceIP>:8090/swUpdateCheck` — the cleanest
-   `:8090` endpoint that triggers exactly one outbound to the
-   configured `swUpdateUrl`. Read-only on the cloud side
-   (doesn't initiate an update); independent of `margeAccountUUID`
-   so it works on factory-reset speakers.
-5. Wait on the registered channel up to `telnetProbeTimeout` (6s).
-6. Telnet `sys configuration swUpdateUrl <originalURL>` — deferred
-   restore so it runs even on the failure path.
-
-The new `/probe/{token}[/*]` catch-all on the root router signals the
-matching channel when the speaker's outbound lands. The response is
-a minimal `<swUpdateIndex/>` so the speaker's `swUpdateCheck`
-doesn't choke on a missing structure. The `/*` sub-path is
-registered because some firmware appends a path component to the
-configured `swUpdateUrl`.
-
-### 9.6 Backend additions worth knowing

-### What you see at the top — the state card
+Two redirect methods are available:
 
-Three rows tell you the speaker's current state at a glance:
+### XML redirect (recommended for first-time / testing)
 
-- **Transports** — whether SSH and Telnet:17000 are reachable. The wizard's choices are driven by these.
-- **Migration State** — three orthogonal axes:
-  - *URL Configuration* — original Bose URLs or AfterTouch URLs (with a special "intercepted via DNS" verdict when the resolv.conf hook is doing the redirect).
-  - *DNS Interception* — none, or `/etc/resolv.conf` hook active.
-  - *CA / TLS* — local root CA installed on the device, with `Trust CA Now` and `Download CA cert` actions inline.
-- **Preconditions** — `remote_services` persistence, account pairing state, and XML config backup presence.
+Uploads a configuration file to the speaker via the SoundTouch Web API. This changes the application-level service URLs without touching the speaker's network configuration. It's the least invasive option.
 
-### The Plan card — the happy path
+The web UI guides you through:
+1. Previewing the config change (current vs. planned XML)
+2. Optionally installing the AfterTouch CA certificate on the speaker (requires SSH; needed for HTTPS)
+3. Applying the XML redirect
+4. Verifying the speaker can reach the local service
 
-Below the state card is the **Plan** card. For most users this is the only thing you'll touch:
+### DNS/DHCP redirect (recommended for permanent / all-device setup)
 
-1. **Target service URL** — pre-filled from your Settings. Edit inline and click *Save as default* to update Settings without bouncing tabs.
-2. **Capabilities** — what transports the speaker exposes and what AfterTouch can offer given those.
-3. **Service URLs** — four URL inputs (margeServerUrl, statsServerUrl, swUpdateUrl, bmxRegistryUrl) pre-filled with canonical defaults. Most users leave them as-is; soundcork users tick the *Soundcork mode* checkbox to append `/marge` to `margeServerUrl`. URL validation runs on every keystroke.
-4. **Account pairing** — pre-filled with the speaker's current account ID. Leave it to keep the existing pairing, change it to re-pair, or click *Generate* to assign a new 7-digit ID on a factory-reset device.
-5. **Suggested plan** — one big green button: *Apply Suggested Plan*. The wizard picks the most conservative recipe for your speaker (XML over SSH with HTTP when SSH works; telnet URL flip with HTTP when only telnet works) and runs it.
+Configures the speaker to use a custom DNS server that resolves Bose cloud hostnames to the local service. This is the most robust method — it covers all Bose endpoints automatically and survives reboots.
 
-### What happens when you click Apply
+Requirements:
+- The AfterTouch DNS server must be running and bound to **port 53** on your network. Enable it in the **Settings** tab (`DNS Discovery` → enabled).
+- HTTPS is required. The web UI walks you through trusting the CA certificate on the speaker (via SSH).
 
-The wizard switches to a visible **Pre-flight checks** panel and runs every applicable verification before touching the speaker:
-
-- **Backend summary re-check** — confirms transports, hostname resolution, and that the URLs you plan to write match what the backend would produce.
-- **HTTPS connection from device** (SSH-capable speakers) — uploads a temporary CA and runs `curl` from the speaker to your service.
-- **Telnet round-trip probe** (SSH-less speakers) — temporarily points the speaker's swUpdateUrl at our service via telnet, triggers `:8090/swUpdateCheck`, and watches the inbound land.
-- **DNS redirection from device** — when DNS interception is part of the plan.
-
-On all-green, the wizard auto-proceeds. On any failure, it pauses with *Proceed Anyway* / *Cancel* buttons so you can override on a known-false-positive (slow DNS, etc.) or fix the underlying issue and retry.
-
-### Customize this migration — for mix-and-match
-
-Expand the `▸ Customize this migration` section to pick any combination of three independent axes:
-
-- **URL flip transport** — XML over SSH / Telnet (Port 17000) / Skip
-- **DNS interception** — None / `/etc/resolv.conf` hook
-- **Local CA install** — checkbox (SSH-only)
-
-Each option carries a per-axis availability hint (e.g. *(SSH unreachable)*, *(already trusted)*) so you see why an option is disabled before you pick. *Apply Custom Plan* runs the chosen combination as a sequence; the same pre-flight panel gates the execution.
-
-> **Note**: DNS interception bundles the CA install on the backend, so a standalone CA-install step is skipped automatically when DNS is part of the plan. The wizard handles this for you.
+The web UI guides you through:
+1. Verifying the DNS server is running and reachable
+2. Installing the CA certificate on the speaker
+3. Configuring the speaker to use the AfterTouch DNS server
+4. Verifying DNS resolution and HTTPS connectivity

 ## Step 6: Reboot and verify
 
-After a successful Apply the wizard auto-expands the Customize section and highlights the **Reboot Speaker** button. Click it (or power-cycle the speaker manually) to apply all configuration changes. The reboot transport is picked automatically from your URL flip choice — telnet reboot for SSH-less speakers, SSH reboot otherwise.
+After migration, **power-cycle the speaker** (unplug and replug). This applies all configuration changes.

-**Precedence**: `*_url` overrides win over the `marge / stats / sw_update / bmx` mode selectors. The setup package applies `applyProxyOptions` first, then `applyURLOverrides` clobbers any field where a literal `*_url` was supplied. So if you send both `marge=proxied&marge_url=http://x:8000/marge`, the literal `http://x:8000/marge` is written.
-
-**Soundcork redirect**: append `/marge` to `marge_url`. The telnet method derives `envswitch boseurls set <margeServerUrl> <swUpdateUrl>` from the final URLs verbatim, so the suffix propagates to the parallel persistence layer automatically — no separate flag needed.

Always attempts to restore the original `swUpdateUrl` even on failure.
-
-**Query Parameters:**
-- `target_url` (optional): defaults to the service's configured `ServerURL`. The probe URL written to the device is `<target_url>/probe/<token>`.

-  "result": {
-    "reached": true,
-    "restored": true,
-    "original_url": "https://worldwide.bose.com/updates/soundtouch",

-    "elapsed_ms": 412,
-    "logs": "…"
-  }
-}
-```
-
-`reached=true` means the device's outbound landed on our `/probe/{token}` route within the timeout. `restored=true` means the runtime `swUpdateUrl` was reverted to its captured original (the envswitch persistence layer is left untouched throughout, so a reboot heals the device naturally if our restore step fails).
-
-#### `GET /probe/{token}[/*]`
-Catch-all endpoint that signals the matching pre-flight probe channel. Used internally by `/setup/telnet-probe/{deviceIP}`; not intended to be called directly by API consumers. Returns a minimal `<swUpdateIndex/>` XML so the device's `swUpdateCheck` doesn't choke on a missing structure.

-//	  Message of type "MargePB.account" is missing required fields:
-//	    devices.device[1].recents.recent[0].source.sourceproviderid
-//
-// Trigger sequence reproduced here:
-//
-//  1. The device POSTs a "laut.fm" recent (location "/custom/v1/playback/...")
-//     against an account that has no Sources.xml yet.
-//  2. classifyLearnedSource fails to recognise /custom/v1/playback/ and the
-//     numeric source id "10003", and historically wrote sourceKey type="INVALID"
-//     with an empty sourceproviderid.
-//  3. The persisted Sources.xml then re-appears in /full with an empty
-//     <sourceproviderid> element inside recents>recent>source, which the
-//     post-marshal cleanup stripped entirely — making the speaker's protobuf
-//     decode fail on a required field.
-//
-// The fix combines three things, all exercised below:
-//
-//   - classifyLearnedSource recognises LocalInternetRadio via the
-//     /custom/v1/playback/ URL pattern and via sourceProviderID == "11".
-//   - mapToFullResponseSource falls back to the canonical SourceProviderID

-# On-Device Installer
-
-Allows to run AfterTouch on SoundTouch devices directly, eliminating the need to run and maintain a separate server on the local network.
-
-## Disclaimer
-
-### Invasiveness
-
-AfterTouch usually normally migrates the SoundTouch devices very noninvasive, by changing the configuration of the device. Running AfterTouch on the device itself is slightly more invasive, because it needs to create a script that starts AfterTouch on boot.
-
-### AfterTouch Availability
-
-Some devices will expose the AfterTouch port, some won't. We currently (May 2026) suspect that the newer generation devices (those with Bluetooth) will expose the port, while the older ones won't. We're still investigating how to expose AfterTouch on all devices. 
-
-If your device doesn't expose the port, you can still use the on-device installer, but you'll need to run AfterTouch on each one of your speakers individually and may only access AfterTouch via ssh port forwarding. This will also make OAuth authentication a little more tricky, but should also work via SSH port forwarding.
-
-### Space Limitation
-
-The storage space on the SoundTouch devices is very limited. At the moment only one AfterTouch installation barely fits on them with enough room for the data it needs to maintain. When installing, make sure that you have removed any binaries and folders of previous installation attempts.
-
-The space limitation also means we are currently unsure on how to update the system, because two binaries are already too large. We are currently working on this - both by checking how we can make the binaries smaller, but also on how we can extend the storage space (e.g. by running AfterTouch from a USB drive).
-
-## Installation
-
-Enable SSH on your SoundTouch device using the usual "Stick with remote_services" method. Connect with the following command.
-
-```bash
-ssh -oHostKeyAlgorithms=+ssh-rsa root@<IP_ADDRESS_OF_SPEAKER>
-```
-
-Then, run the following command to install AfterTouch on the device.
-
-```bash 
-rw && curl -sSL https://raw.githubusercontent.com/gesellix/Bose-SoundTouch/main/scripts/on-device-install/install.sh | sh
-```
-
-After the installation check if you can access AfterTouch from your local device by navigating to `http://<IP_ADDRESS_OF_SPEAKER>:8000`. If you can access the AfterTouch UI, you're good to go! If not, you may need to run AfterTouch on the speaker via SSH port forwarding.
-
-```bash
-ssh -L 8000:localhost:8000 root@<IP_ADDRESS_OF_SPEAKER>
-```
-
-## Updating AfterTouch
-
-To update AfterTouch, simply run the installation command again. The installer will check if there's a new version available and update it if necessary.
-
-## Uninstallation
-
-Before uninstall, you might want to revert the migration, especially the changes to the server URLs (even though having configured an unresponsive local server probably is about as bad as having configured unresponsive Bose servers). To uninstall AfterTouch, run the following command on the speaker.
-
-```bash
-curl -sSL https://raw.githubusercontent.com/gesellix/Bose-SoundTouch/main/scripts/on-device-install/uninstall.sh | sh
-```
