v26.10.2 (#1672)

* fix: keep concurrent ssh pool connects from overwriting each other (#1619)

* fix: stop auto-accepting changed jump host keys (#1620)

A jump hop whose key no longer matched the pinned fingerprint was
silently accepted and the pin overwritten. Background status probes
reconnect to jump hosts every cycle, so a MITM on that hop got the
credentials with no user interaction. Changed jump host keys now go
through the same path as any other host: prompt when there is a
terminal socket, otherwise refuse.

* fix(electron): validate external login URL scheme and callback port (#1621)

* fix(plugins): read artifact manifest with the same tar parser as the unpack (#1622)

The consent check read the first manifest.json with a hand-written tar
reader, while the unpack keeps the last one and also follows pax and
long-name headers. An archive with two manifests could pass the check
with one capability list and get granted another. Read the manifest
with node-tar, count only plain files, and refuse archives that hold
more than one manifest.json.

* fix: only trust the server's origin in the desktop login frame (#1624)

The desktop sign-in iframe accepted AUTH_SUCCESS and system browser requests from whatever page it had navigated to, and posted replies (including 2FA temp tokens) to any origin. Messages must now come from the server's origin and replies are posted to it.

The web UI also treated any framing page as the desktop app and posted the JWT to it. It now also requires the Termix-Desktop user agent.

* fix: check trusted proxy login against nginx's peer, not nginx (#1625)

The backend only sees the bundled nginx on loopback, so the allowlist
could only work by trusting 127.0.0.1, which let any client that reached
nginx log in as anyone by sending the identity headers. nginx now passes
its own TCP peer (before real_ip rewriting) in X-Termix-Proxy-Peer, and
loopback connections are judged by that address instead.

* fix: keep foreign keys on during user data import (#1626)

Import credentials before hosts and remap the file's credential ids to
the ones created here, so hosts and protocol logins no longer point at
another server's ids. With rows written in dependency order, the import
no longer turns off SQLite foreign keys on the shared connection. The
uploaded file is now removed on every exit path.

* fix: enforce unique usernames (#1628)

* fix: enforce unique usernames

Registration checked for a taken name, hashed the password, then
inserted, with nothing in the schema enforcing uniqueness. Concurrent
sign-ups could create two accounts with one name, after which login,
password reset, proxy login and admin lookups by username picked
between them arbitrarily.

Add a unique index on users.username for every dialect. Existing
duplicates are renamed (later rows get a -<id> suffix, the oldest keeps
the name) rather than deleted. Registration and admin user creation now
return the same 409 when the insert loses the race.

* fix: avoid username collisions during migration

* fix: don't auto-enable synced plugins signed only by a server-sent key (#1623)

* fix: don't auto-enable synced plugins signed only by a server-sent key

Registry keys a linked server sends still let its plugins load on the desktop, but no longer count as a signer for switching them on or copying their grants. Keys the desktop added itself keep their trust.

* fix: enforce local plugin trust across remote source labels

* fix: require positive local trust for synced plugin keys

* fix(desktop): harden external editor and session cookie IPC (#1627)

* fix(desktop): stop the renderer choosing the external editor binary or reading the session cookie

open-external-editor now launches only the editor saved from a file dialog
and refuses to hand executable file types to the OS opener. The unused
get-session-cookie and wait-session-cookie channels, which returned the
httpOnly jwt, are removed.

* fix: validate setting keys before editor authorization

* fix(sidebar): sort hosts by IP address numerically (#1629)

* fix(desktop): find spawn-helper in universal macOS builds (#1630)

The universal build ships app-arm64.asar and app-x64.asar instead of
app.asar, so node-pty's helper path rewrite never pointed at the
unpacked copy and every local terminal failed with posix_spawnp failed.

* fix(sync): send shared hosts with text columns in their stored form (#1631)

resolveHostById turns forceKeyboardInteractive into a boolean, and the
shared-host export passed it on as is. A desktop could not bind the boolean
into the text column, so every shared host failed to apply.

* fix: drop ssh_data.vault_profile_id so removing the vault plugin keeps hosts writable (#1633)

The vault plugin renames vault_profiles to p_vault_profiles, and SQLite
rewrites ssh_data's foreign key to follow it. Uninstalling the plugin then
dropped p_vault_profiles and left ssh_data pointing at a missing table, so
creating, cloning and deleting hosts failed with "no such table:
main.p_vault_profiles". Postgres and MySQL refused the uninstall instead.

The column was already copied into the vault plugin's host settings by 2.9,
so retire it on every engine. The SQLite boot drop also repairs databases
already in the broken state; MySQL drops the column's foreign key first.

* fix(sync): let a linked desktop enable mirrored plugins it does not trust on its own (#1632)

* fix(sync): let a linked desktop enable mirrored plugins it does not trust on its own

* fix(sync): switch off an untrusted mirrored plugin when the server updates it

* fix: require local consent for mirrored plugin activation

* docs: describe consent fields on the plugin state endpoint

* fix(i18n): keep Indonesian technical terms consistent (#1636)

Use the English terms Indonesian users know for tunnel, snippet, deploy,
file manager, remote desktop, jump host, passphrase, sidebar, toolbar,
endpoint, browser and SSH agent, instead of mixing literal translations
(terowongan, cuplikan, terapkan, bilah sisi, titik akhir, ...) with the
English words. Match the split shortcuts to the split screen menu.

Also fix the user data export description, which said secrets are
encrypted while the English says they are decrypted.

* fix(settings): leave user manage view when switching admin sections (#1649)

The admin panel stays mounted across Settings pages, so an open user
manage view kept replacing every other admin section until Back to users
was clicked. Reset it whenever the selected section changes.

* fix(sync): don't delete a local row when the server can't send its copy (#1650)

* fix(sync): don't delete a local row when the server can't send its copy

A push conflict on a live record whose server row failed to serialize
came back as row: null, deleted: false, and the desktop treated that as
a delete. The server now rejects that op as unavailable, the desktop
never deletes on a conflict without a row, and serialization failures
are logged.

* fix(sync): retry temporarily unavailable records

* fix: smooth host editor jumps to lower sections

* chore: add changelog entries for 26.10.2 fixes

* fix: stop building ssh2 native crypto in the docker image (#1644)

* chore: test that an update keeps a changed auth type (#1601)

* feat: option to hide the sidebar after opening a host (#1652)

* feat: sort the dashboard host status card (Plugin-Host-Metrics#6)

* fix: let the hover side menu overlay content instead of resizing it (Plugin-Remote-Desktop#2)

* fix: say the server is down and keep retrying instead of a database error (#1637)

* fix: show why a client tunnel failed to start (Plugin-Tunnels#2)

* fix(sdk): skip comment-only chunks when splitting migrations

* feat: setting to let the hover side menu push content again

* fix: use the vite proxy for plugin sockets on any dev port

* feat(sdk): let a plugin raise its public route rate limit

* chore: update translations

* chore: add the overview video to the readme

* chore: update the overview video and add a play button to its thumbnail

* feat: plugin builds bundle worker entries and import wasm and fonts as bytes

* feat: plugin packs include LICENSE and NOTICE

* chore: drop guacd from compose files and dev runner

* chore: update remote desktop origin comment for the built-in engine

* fix: show plugin names and descriptions in the UI language (#1658)

* fix: show plugin names and descriptions in the UI language

Read plugin.name and plugin.description from each plugin's own locale
namespace, falling back to the manifest, everywhere core shows a plugin's
name: the Plugins manager, onboarding picker, host editor tabs and
sections, host filters and bulk actions, beta updates, interface presets
and plugin crash/loading notices.

* docs(sdk): document plugin.name and plugin.description locale keys

* fix(hosts): reject or infer a missing authType on host create (#1664)

Creating an SSH host through the API without authType hit the NOT NULL
auth_type column and came back as a 500. The create route now infers the
type from the credential, key or password in the body, falls back to the
host defaults, and otherwise answers 400. A non-string authType is a 400
on create and update.

* chore: changelog for merged plugin name and host auth type PRs

* fix: move macOS split pane navigation to Cmd+Option+Arrow

* fix: pick a free port for the desktop backend when 30001 is taken (#1663)

* feat: build the Windows desktop app for ARM64 (#1615)

* fix(sync): keep the changes cursor within the 32-bit seq column (#1665)

The desktop learned the server's entity types by asking for changes after
Number.MAX_SAFE_INTEGER. sync_records.seq is a 32-bit integer on Postgres,
which rejects that bound value, so every pass needing the probe failed with
22003 out of range.

The server now clamps the cursor to the largest seq the column holds and
answers 400 for a cursor or limit that is not a non-negative integer. The
desktop asks for a one-row page from its saved cursor instead.

* fix(audit): coalesce identical plugin routine audits so they cannot flush the log (#1667)

Successful plugin_as_user and plugin_service_* entries written by a plugin
with the same user, action, resource and details are recorded once per
10 minutes. Failures and every other action are still written each time.

* feat(plugins): publish host.created when a host is added (#1668)

Plugins that keep an inventory of hosts had no way to hear about a new
one short of polling. Core now publishes host.created with the same
{ hostId, userId } payload as host.updated wherever a host row is
created: the host create route, ctx.hosts.create, JSON and SSH config
bulk import, database file import, and sync writing a host it did not
have yet.

* fix: show the login for signed-out full-screen view links and return to them (#1669)

A ?view= link opened without a session spun forever: the gate rendered
the bare view when the session check failed, so the plugin runtime never
started and the view never registered. A regular browser now keeps the
link in sessionStorage, shows the normal login and opens the link again
after any login, including redirect logins. Only same-origin paths with
a view are restored. The desktop app, embedded sign-in frames and guest
views keep their current behavior.

* fix(desktop): apply linked server proxy headers and certificate exception to WebSockets (#1670)

* fix(desktop): send linked server proxy headers on WebSocket upgrades

isLinkedOrigin compared the request origin with the link's http(s)
origin, so the terminal WebSocket (wss://host/...) never matched and its
upgrade went out without the proxy headers and basic auth. Behind a
forward-auth proxy that upgrade was redirected to the login and the
terminal closed with "connection closed unexpectedly". ws and wss now
count as http and https for the comparison, the same mapping the
WebSocket handshake itself uses, with host and port still matched
exactly.

* fix(desktop): allow a linked server's self-signed certificate for its WebSockets

isInvalidCertificateAllowedForUrl compared the URL with a local
getOrigin copy, so wss://host never matched the link's https://host
origin and an allowed self-signed certificate did not cover the
terminal and tunnel sockets. It now uses linkedServer.isLinkedOrigin,
which maps ws and wss the same way as the proxy headers, and the local
copy is removed.

* feat(sdk): let plugins mint a short-lived user session and read a user's locale (#1666)

ctx.auth.issueUserToken(userId, { purpose, ttlSeconds }) gives background
work a session for calling Termix's own API as an existing user. It needs
users:impersonate, defaults to 300s and is capped at 900s, is stored as a
normal session row marked as plugin-issued, and every issue is audited.
Such sessions are refused on routes that change the user's password,
second factors, API keys or linked logins.

ctx.users.getLocale(userId) reads the user's UI language under users:read.

SDK 1.0.11, plugin API 1.3.0.

* chore: changelog for merged sync, audit, event and desktop PRs

* feat: add shell.rightEdge slot so plugin panels can push the page over

* chore: pin bundled plugins to the latest releases

* chore: lint, format, and bump version to 26.10.2

 # Changelog
 
+## 26.10.2
+
+### Added
+
+- Hide sidebar after opening, in Customize Sidebar, closes the host list once you open a host
+- Sort the dashboard's Host Status card by name, IP address or status
+- Windows on ARM builds of the desktop app (installer, MSI and portable)
+- Plugins get an event when a host is added
+- Plugins can start a short-lived session as a user and read the user's language, for tasks that run without a browser
+- Plugins can pin a panel to the right edge of the window that pushes the page over
+
+### Changed
+
+- The Docker Compose files no longer start a guacd container. npm run dev -- --guacd also points remote desktop at the guacd it starts
+- The side menu now opens over the page when it expands on hover, so open sessions like remote desktop are not resized each time. Turn on Push content when it expands in Settings to get the old behavior back
+- On macOS, moving between split panes is now Cmd+Option+Arrow, so Option+Arrow can move the cursor by word in a terminal
+
+### Fixed
+
+- Picking a section lower down in the host editor, like Warpgate, stuttered on the way and sometimes stopped before it got there
+- Sorting hosts by IP address put 10.0.0.210 before 10.0.0.3
+- The local terminal failed to start in the universal macOS build
+- Hosts shared with you never showed up on a linked desktop
+- A linked desktop could never turn on an unsigned plugin the server had enabled
+- Creating, cloning or deleting hosts failed with "no such table: main.p_vault_profiles" after the Vault plugin was removed
+- Opening a user in Settings, Users blocked the other admin sections until you went back to the user list
+- A linked desktop could keep showing the same sync conflicts, or delete a local host, when the server could not send its copy
+- Usernames are now unique
+- Importing user data keeps foreign keys on
+- Trusted proxy login checks the address nginx saw, not nginx itself
+- The desktop login frame only trusts the server's own origin
+- External login URLs and callback ports are checked on the desktop app
+- A changed jump host key is no longer accepted without asking
+- Synced plugins signed only by a key the server sent are no longer turned on by themselves
+- Two connects to the same host at once could overwrite each other's connection
+- Indonesian uses the same technical terms everywhere
+- When the server was down or still starting, the login page said it could not connect to the database and stopped trying. It now says the server is not responding and continues on its own once the server is back
+- nginx answered 404 instead of 502 while the backend was down
+- A client tunnel that could not start always said "Endpoint SSH connection closed" on the desktop app instead of the real reason, like the target refusing the connection
+- The Docker server crashed and restarted every few hours in ssh2's native crypto on Node 24
+- Plugin names and descriptions showed in English in the plugin manager, setup picker and host editor no matter the UI language
+- Creating a host through the API without an auth type failed with a server error. It now picks the type from the credential, key or password, or says auth type is required
+- The desktop app would not start its local server when another program used port 30001. It now picks a free port on its own
+- A linked desktop could never finish syncing with a server on Postgres
+- Routine plugin activity filled the audit log and pushed out real security entries
+- Opening a full-screen view link while signed out showed a spinner forever. It now shows the login and opens the link after
+- A linked desktop behind a proxy that needs extra headers, or with an allowed self-signed certificate, could not open remote terminals or tunnels
+
+## 26.10.1
+
+### Added
+
+- Slovak, Croatian, Slovenian, Lithuanian, Latvian, Estonian and Malay
+- The desktop app can update itself. Pick Automatic, Ask first or Never in Settings, Updates. Store and package manager installs keep updating the way they do now
+- Community plugins. Turn on the community registry in Plugins, Registries to browse and install plugins made by other people, each version reviewed before it is listed
+- Custom plugin registries. Add your own registry by its index URL; its signing key is pinned when you add it
+
+### Changed
+
+- Every language is now fully translated, in Termix and in every plugin, and stays up to date with each release
+- Languages with more than two plural forms, like Russian, Polish and Arabic, now use the right one
+- The Plugins tab shows how many times each plugin was downloaded, in a Downloads column
+- Plugins, Browse hides plugins you already have. Turn on Show installed to see them
+
+### Fixed
+
+- Regional browser languages like `es-MX`, `pt` or `zh-HK` showed English instead of the closest translation
+- Counts like "1 keys" or "Moved 1 host(s)" now use the singular
+- Plugin updates on the desktop app, synced or installed from the Plugins tab, failed to start with "Cannot find package"
+- The desktop app showed plugins that only run on the server as not running and out of date
+- Keep the terminal WebSocket open past nginx's 60s default
+- Plugin download counts now show in the Plugins tab without waiting for the background check
+- Clicking into a saved password, key passphrase or sudo password field and saving without typing erased it, which stopped sudo autofill
+- The desktop app now says when its data is from 2.8 or older and needs 2.9 first, instead of only saying the local server could not start
+- Client tunnels on the desktop app stopped with "Endpoint SSH connection closed" when a reverse proxy dropped their idle connection
+- Typing right after opening a host from the sidebar went to the host search instead of the new session
+- SSH config import failed on files that put a tab or `=` between a keyword and its value
+- App icons and the favicon have rounded corners again

 ## Overview
 
-Termix is a free, open source, self-hosted platform for managing your servers, built on plugins. The core is small. It keeps your hosts, credentials, users, sharing and sessions. Everything else, like the SSH terminal, remote desktop, file manager, Docker and metrics, is a plugin you can turn on, turn off or remove.

+What every install has, with or without plugins:
 
-- **Hosts:** Save hosts in nested folders with tags and parent hosts, bulk edit, import and export, and use Quick Connect for one-off connections
-- **Credentials:** Reuse saved passwords and keys across hosts, with host defaults you can set for the server, a user or a folder
-- **Sharing and Roles:** Share hosts, credentials and folders with users or roles at four levels: connect, view, edit and manage
-- **Accounts:** Local accounts, sessions you can see and revoke, trusted devices, API keys and an audit log
-- **Security:** Passwords, keys and other secrets are encrypted per user, and the database can be encrypted on disk
-- **Desktop Sync:** The desktop app runs on its own and can link to a Termix server to keep an offline copy of your account
-- **Interface:** Tabs and split screen, a command palette (double tap left shift), rebindable shortcuts, themes, branding and around 30 languages
-- **Databases:** SQLite by default, with PostgreSQL and MySQL supported too

 ### Cloud Hosting
 
-You can run Termix on a VPS instead of inside your own network. If Termix runs on the network it manages, an outage takes Termix down with it, right when you need it to fix things. Running it somewhere else keeps it reachable, gives you a static IP and lets you get in from anywhere without a VPN or port forward.

 # Changelog
 
+## 1.0.11
+
+Plugin API 1.3.0.
+
+### Added
+
+- `ctx.auth.issueUserToken()` mints a short-lived session for a user, for calling Termix's own API as them from background work. Needs `users:impersonate` and `engine.api` 1.3
+- `ctx.users.getLocale()` reads a user's UI language. Needs `users:read` and `engine.api` 1.3
+
+## 1.0.10
+
+### Changed
+
+- `termix-plugin pack` includes the plugin's `LICENSE` and `NOTICE` files, so third-party notices ship with it
+
+## 1.0.9
+
+### Added
+
+- Worker entries in `package.json` `termix.workers`, each bundled on its own into `dist/workers/<name>.js`
+- A `.wasm`, `.ttf` or `.otf` import gives the file's bytes, in `termix-plugin build` and in plugin tests
+
+### Fixed
+
+- The plugin guide listed jszip, guacamole-lite and @anthropic-ai/sdk as shared packages, but they are bundled
+
+## 1.0.8
+
+### Added
+
+- `publicRateLimit` on `ctx.http.router()`, for a plugin whose public routes serve a proxied page
+
+## 1.0.7
+
+### Fixed
+
+- A migration file, or a part of one, holding only comments made core fail to start the plugin
+
+## 1.0.6
+
+### Added
+
+- `PLUGIN-GUIDE.md`, a guide to building, testing and releasing a plugin, written so AI coding tools can read it too

+# Termix plugin guide
+
+SDK 1.0.11 | Plugin API 1.3.0
+
+This guide is for anyone, person or AI coding tool, building a Termix plugin. It ships inside
+`@termix-ssh/plugin-sdk`, so the copy in your `node_modules` always matches the SDK you have installed.
+Run `npm update @termix-ssh/plugin-sdk` to get the newest one.
+
+If this guide and the SDK's TypeScript types disagree, the types are right. They live next to this file
+in `dist/*.d.ts`. The long form of everything here is at https://docs.termix.site/develop, and the raw
+Markdown of each page is at
+`https://raw.githubusercontent.com/Termix-SSH/Docs/main/develop/<page>.md` (for example
+`develop/backend.md`), which is easier for tools to read than the site.
+
+## What a plugin is
+
+Termix is self-hosted, plugin-based server management. Core keeps hosts, credentials, users, sharing and
+the shell. Everything else, even the SSH terminal, is a plugin built with this SDK.
+
+A plugin is:
+
+- `manifest.json`: what it is, what it adds and what it may do. Termix reads it without running any code.
+- A backend, `src/backend/index.ts`, run inside the Termix server process. It exports `activate(ctx)`.
+- A frontend, `src/frontend/index.tsx`, run in the browser in the same page as Termix. It exports
+  `activate(app)`.
+
+There is no sandbox. Capabilities make a plugin honest and easy to audit, but code runs with the server's
+rights. Write it as if an admin will read every line, because reviewers do.
+
+## Hard rules
+
+Break one of these and the plugin fails to load, fails validation or gets rejected in review.
+
+1. Import only `@termix-ssh/plugin-sdk/*`, your own files and npm packages. Never import Termix's own code.
+2. Create everything inside `activate`. No servers, timers, sockets or connections at the top of a module.
+   Disable then enable runs `activate` again on the same module, and it must work without a restart.
+3. Clean up what you make yourself with `ctx.disposables.add(fn)` (backend) or `app.onDispose(fn)`
+   (frontend). Things made through `ctx` and `app` are cleaned up for you.
+4. Never call `process.exit` or touch signals.
+5. Never open your own SSH connection. Use `ctx.ssh` so jump hosts, proxies, host keys, every auth type and
+   sharing work the way the user set them up.
+6. Outbound HTTP goes through `ctx.fetch` (needs `network:outbound`), not a raw `fetch` or axios.
+7. Ask for the fewest capabilities you can. A call that needs one you didn't list throws
+   `PluginCapabilityError`.
+8. Never take a user id from a request body or a service caller. Use `ctx.currentActor()`.
+9. Check permissions on the backend. Frontend checks only hide UI.
+10. Call `await ctx.db.persist()` after every database write. On SQLite a write without it can be lost on
+    restart.
+11. Never use `.returning()` in a query. MySQL doesn't have it. Read a new row back by a key you chose.
+12. Never edit a migration that has shipped. Termix checks a checksum and refuses to start the plugin. Add a
+    new one.
+13. Never index a `text()` or `json()` column. Use `varchar(n)` for anything you index.
+14. Never hard code UI text. Every string goes in `locales/en.json` and is read with `t()`.
+15. The plugin `id` never changes once released. It names your tables, routes and permissions.
+16. The version in `manifest.json`, `package.json` and the newest `CHANGELOG.md` section must match.
+17. Put an `@openapi` JSDoc block above every route.
+18. No obfuscated or minified source, and no code downloaded and run at runtime.
+19. No tracking, telemetry or network calls the user didn't ask for. If you need one, make it off by
+    default and explain it in your docs.

+
+## Done checklist
+
+Before you call a change finished:
+
+- [ ] `npm test` passes
+- [ ] `npm run typecheck` passes
+- [ ] `npm run validate` passes with no warnings you can fix
+- [ ] `npm run build` passes
+- [ ] `npm run format:check` passes
+- [ ] `npx termix-plugin migrations --check` passes (you ran `npm run migrations` after changing tables)
+- [ ] New strings are in `locales/en.json`, and `plugin.name` / `plugin.description` match the manifest
+- [ ] New routes have an `@openapi` block and a test, including without the permission
+- [ ] New env vars are listed in `env` in the manifest
+- [ ] `docs/` and the "About this plugin" section of `AGENTS.md` still match what the plugin does
+- [ ] User facing changes are in `CHANGELOG.md` under the version they will ship in

+
+### The actor
+
+In a route the actor is the signed-in user, set by Termix. `ctx.currentActor()` returns it. Background
+work with no request (a timer, an event) uses `ctx.asUser(userId, fn)`, which is audited and still applies
+that user's permissions.
+
+Background work that must call Termix's own HTTP API (the Termix CLI, say) asks for a session with
+`ctx.auth.issueUserToken(userId, { purpose, ttlSeconds })` and sends it as `Authorization: Bearer <token>`.
+It needs `users:impersonate` and `engine.api` `^1.3`, lasts 300 seconds by default and 900 at most, and is
+audited as `plugin_user_token_issued`. The user's permissions apply, and it is refused on routes that change
+their password, second factors, API keys or linked logins. `ctx.users.getLocale(userId)` gives the user's
+UI language, like `zh_CN`, or null, for writing to them in it.
+
+### Routes
+
+Routes live at `/plugin-api/<id>/`, sockets at `/plugin-ws/<id>/`, on the main Termix port. You never need
+your own port or an nginx change. Before your handler runs, Termix checks sign in, sets the actor, answers
+503 if the plugin is off, parses JSON up to 2 MB and catches errors.
+
+```ts
+router.use(ctx.rbac.require("use") as never);
+
+/**
+ * @openapi
+ * /plugin-api/hello/notes:
+ *   post:
+ *     summary: Add a note for the signed-in user
+ *     tags:
+ *       - Hello
+ *     requestBody:
+ *       required: true
+ *       content:
+ *         application/json:
+ *           schema:
+ *             type: object
+ *             properties:
+ *               text:
+ *                 type: string
+ *     responses:
+ *       201:
+ *         description: Note added
+ *       400:
+ *         description: Missing or empty text
+ */
+router.post("/notes", async (req, res) => {
+  const text = typeof req.body?.text === "string" ? req.body.text.trim() : "";
+  if (!text) return res.status(400).json({ error: "text is required" });
+  const db = await ctx.db.client<BetterSQLite3Database>();
+  await db
+    .insert(notesTable)
+    .values({ userId: ctx.currentActor() as string, text });
+  await ctx.db.persist();
+  res.status(201).json({ success: true });
+});
+```
+
+- The `@openapi` path is the full path, starting with `/plugin-api/<id>/`. `build` turns these into
+  `dist/openapi.json` and the docs site renders them.
+- `ctx.http.router({ public: ["/webhook/:token"], bodyLimit: "20mb", rawBody: false })`. Public routes
+  have no actor: check their token yourself. Core allows 120 public requests a minute per address;
+  `publicRateLimit` raises that for a proxied page that loads its own assets.
+- `ctx.http.baseUrl(req)` is the public address, for callback URLs.
+- `ctx.ws.route("/live", (socket, conn) => ...)`. Long lived sockets should check
+  `conn.isDataUnlocked()` per message.
+- `ctx.rbac.require("manage")` on a single route, `await ctx.rbac.has("manage")` in code. A full id like
+  `hosts.edit` checks a core permission.
+- Host access: `ctx.hosts.checkAccess(hostId, "connect" | "view" | "edit" | "manage")`.
+
+### Errors
+
+Errors from routes, sockets, listeners and timers count against an error budget. Five in a minute and
+Termix turns the plugin off (state `failed`). A 4xx you send on purpose doesn't count. Validate input and
+send 400s instead of throwing.
+
+### SSH
+
+```ts
+const { client, dispose } = await ctx.ssh.connect(hostId, {
+  purpose: "hello",
+  profile: "background",
+});
+try {
+  // use the ssh2 client
+} finally {
+  dispose();
+}
+```
+
+`ctx.ssh.withConnection(hostId, { pool, purpose }, fn)` borrows a pooled connection for frequent short
+commands. `@termix-ssh/plugin-sdk/host-commands` has helpers to detect the OS and run package manager and
+sudo commands. Hosts from `ctx.hosts` never carry secrets. Pass the host or its id to `ctx.ssh`.
+
+### Events, timers, alerts, services
+
+```ts
+ctx.events.on("host.deleted", ({ hostId }) => cleanUp(hostId)); // core topics need events:core
+ctx.events.emit("plugin.hello.greeted", { name }); // your own: plugin.<id>.<name>
+ctx.schedule.every(60_000, () => refresh(), { jitterMs: 5_000 });
+```
+
+- Alerts go through `ctx.notify.send` (`notify:send`). Never build your own notification system.
+- Offer a service: declare it in `provides` with a version and a permission, then
+  `ctx.services.provide("hello.greetings", impl)`. The name starts with your id. Methods read the caller
+  from `ctx.currentActor()`.
+- Use a service: declare it in `requires`, then `ctx.services.get<T>("snippets.access")`. It returns
+  nothing while no provider runs, so always handle that.
+
+### Shared packages
+
+These come from Termix and are never bundled: `@termix-ssh/plugin-sdk`, `express`, `ssh2`, `ws`, `multer`,
+`cookie-parser`, `axios`, `drizzle-orm`, `sharp` and every Node builtin. List the ones you use in
+`peerDependencies`. Any other npm package is bundled.
+
+### Workers and WebAssembly
+
+Heavy work (decoding, encoding, parsing) belongs in a worker thread so it never blocks the server. Name
+each worker entry in `package.json`:
+
+```json
+"termix": { "workers": { "engine": "src/backend/engine/worker.ts" } }
+```
+
+`build` bundles it alone into `dist/workers/engine.js`; start it with
+`new Worker(new URL("./workers/engine.js", import.meta.url))`. A worker bundles everything it imports and
+can't use the shared packages above, so it must not import `@termix-ssh/plugin-sdk`. Talk to it with
+`postMessage`.
+
+Importing a `.wasm`, `.ttf` or `.otf` file gives its bytes as a `Uint8Array`, in `build` and in tests, so a module ships
+inside the bundle with no file to find. Compile it once on the main thread with `new WebAssembly.Module`
+and post that to each worker. Add `declare module "*.wasm" { const bytes: Uint8Array; export default bytes; }`
+to a `.d.ts` in the plugin.
+
+## Database
+
+Needs `db:own`. Define tables once in TypeScript, generate migrations for SQLite, PostgreSQL and MySQL,
+query with [Drizzle](https://orm.drizzle.team/).
+
+```ts
+// src/backend/tables.ts
+import {
+  defineTable,
+  id,
+  refUser,
+  text,
+  timestamp,
+} from "@termix-ssh/plugin-sdk/db";
+
+export const notes = defineTable(
+  "notes",
+  {
+    id: id(),
+    userId: refUser(),
+    text: text().notNull(),
+    createdAt: timestamp().notNull().defaultNow(),
+  },
+  { indexes: [{ name: "idx_p_hello_notes_user_id", columns: ["userId"] }] },
+);
+
+export const tables = [notes]; // termix-plugin migrations reads this
+```
+
+The table is stored as `p_<id with dashes as underscores>_notes`. Index names should use the same prefix.
+

+| `varchar(n)`                                   | String up to `n` (255 default). Indexable                                   |
+| `integer()`, `bigint()`, `real()`, `boolean()` | Numbers and booleans                                                        |
+| `timestamp()`                                  | A time, stored as text                                                      |
+| `json()`                                       | JSON stored as text. Not indexable                                          |
+| `encryptedText()`                              | Text encrypted with the owning user's key                                   |
+| `refUser()`                                    | A user id. Rows are deleted with the user and included in their data export |
+| `refHost()`                                    | A host id. Rows are deleted with the host                                   |
+
+Modifiers: `.notNull()`, `.unique()`, `.primaryKey()`, `.default(value)`, `.defaultNow()`.
+
+After any change to `tables.ts`, run `npm run migrations` and read the three new files. Renames and type
+changes are refused rather than guessed: write those by hand, for all three databases. A migration may only
+touch your own tables. `createTestDb` applies them in tests, so a broken one fails `npm test`.
+
+Query through `const db = await ctx.db.client()`, then `await ctx.db.persist()` after writes
+(`persist({ lazy: true })` for frequent low value writes). `ctx.db.dialect` says which database runs.
+
+Other storage: `ctx.kv` for a few values, `ctx.settings` for settings, `ctx.secrets` for secrets,
+`ctx.files.dataDir()` for files. To sync a table to a linked desktop, use `ctx.sync.registerEntity` and
+`contributes.syncEntities`. The entity name is part of the protocol and never changes.

+Hooks from `@termix-ssh/plugin-sdk/frontend`: `useTranslation`, `usePermission`, `useSettings`, `useHost`,
+`useHosts`, `usePluginApi`, `useCurrentUser`, `useTheme`, `useToast`, `useDocsUrl`, `useTabs`,
+`useSlotContributions`, `useSshAuthTypes`, `useExtensions`.
+
+Shared from Termix and never bundled: `react`, `react-dom`, `i18next`, `react-i18next`, `sonner` and the
+SDK's `frontend` and `ui`. Anything else, like `lucide-react`, is bundled. A host your code gets only carries
+your own host settings, under `host.pluginSettings[<id>]`.
+
+Slots you can fill include `terminal.toolbar`, `terminal.toolbarStatus`, `terminal.sidePanel`,
+`terminal.overlay`, `dashboard.counters`, `dashboard.hostMetrics`, `admin.userTabs`, `hosts.importMenu`,
+`hosts.panel`, `credentials.badges`, `shell.overlay`, `shell.rightEdge` and `tab.menu`. See
+https://docs.termix.site/develop/more-extension-points.
+
+## Looking native
+
+Build UI from `@termix-ssh/plugin-sdk/ui` so it matches Termix and follows the theme. The full list of
+exports with props is `ui.api.txt` in the Termix repo
+(https://github.com/Termix-SSH/Termix/blob/main/packages/plugin-sdk/ui.api.txt).
+
+- Square: panels, cards and containers have no rounded corners. Small controls may stay rounded.
+- Flat: borders, not shadows. Use theme tokens like `border-border`, `bg-background`,
+  `text-muted-foreground`, `text-destructive`. One accent, `text-accent-brand`. Don't add colors.
+- Small type: most text 11 to 13px.
+- No new modal dialogs. Ask with `useConfirm()`, open views in place with `InlineView`, and use
+  `PanePrompt` for small prompts.
+- Every tab or panel sits in `PanelShell`. Lists use `PanelList` and `ListRow`, add with `AddButton`,
+  forms end with `FormFooter`, empty lists show `EmptyState`.
+- Forms: `TextField`, `NumberField`, `SelectField`, `SwitchRow`, `SecretField`, `SettingRow` and friends.
+- Host sessions use `ConnectionGate` for the whole connect flow (host keys, TOTP, passphrases, errors).
+- Mobile: check `useIsMobile()` and give small screens a layout that works. The desktop app always uses the
+  desktop layout.
+- Tailwind classes work. `build` compiles the ones you use against Termix's theme.
+- Link to your docs with `DocsLink` or `PanelShell`'s `docs` prop, never a hard coded URL.
+
+## Settings
+
+Declare them in `contributes.settings` and Termix draws the form, stores values, encrypts secrets and
+checks saves. You don't build settings UI.
+
+- Scopes: `admin` (for everyone), `user` (each person), `host` (a section in the host editor, with an
+  `enableKey` switch first).
+- Types: `boolean`, `string`, `number`, `select`, `multiselect`, `secret`, `textarea`, `json`, `custom`.
+- Options: `labelKey`, `descriptionKey`, `placeholderKey`, `default`, `options`, `min`, `max`, `requires`,
+  `group`, `permission`, `hidden`, `component`.
+- Read: `ctx.settings.get(key)`, `getUser(userId, key)`, `getHost(hostId, key)`. Write: `set`, `setHost`.
+  React: `ctx.settings.onChange`. Check: `ctx.settings.onValidate("admin", values => ({ key: "message" }))`.
+- Frontend: `useSettings("user")` gives values and `save`.
+
+Prefer settings to environment variables. Use an env var only for something needed before Termix starts.
+
+## Permissions
+
+Declare short names in `contributes.permissions`. Termix registers them as `<id>.<name>`. `defaultRoles`
+gives them to the built in `admin` and `user` roles on first install. You can't claim a core group
+(`hosts`, `credentials`, `admin`) or another plugin's. Labels are locale keys.
+
+## Translations
+
+Every string goes in `locales/en.json`, nested by area. Manifest keys (`titleKey`, `labelKey`) and `t()`
+read it from your own namespace. Unknown keys fall back to Termix's shared strings like `common.save`.
+Plurals use `_one` and `_other` with `t("hosts", { count })`. Other languages go in
+`locales/translated/<code>.json` (like `de_DE.json`) with the same keys. Keep `{{placeholders}}` as they are.
+Untranslated strings show in English.
+
+Termix shows your plugin's name and description in the plugin manager, the setup picker and settings.
+Put them in `locales/en.json` as `plugin.name` and `plugin.description`, with the same text as `name` and
+`description` in the manifest, so they get translated too. Without them, the English manifest text shows in
+every language.
+
+```json
+{
+  "plugin": {
+    "name": "Host Metrics",
+    "description": "Live CPU, memory, disk, network and GPU stats."
+  }
+}
+```
+
+## Docs
+
+`docs/index.md` is the first page: what the plugin does in a sentence or two, how to turn it on, how to use
+it. More pages sit next to it with `title` and `order` front matter. Plain Markdown, no MDX. Images go in
+`docs/img/`.
+
+Don't write by hand what is generated: features, settings, permissions, capabilities, env vars, services,
+the API reference (from `@openapi`) and the changelog. Write short sentences in plain words and name
+buttons exactly as the UI does.
+
+## Auth and protocols
+
+Login methods, second factors and SSH auth types need `auth:provide`, which is high risk and reviewed
+closely. Declare ids in `contributes.auth` and register them with `ctx.auth.registerLoginMethod`,
+`registerSecondFactor` or `registerSshAuthProvider`. Connection protocols go in `contributes.protocols`
+and `app.registerHostProtocol`. Read https://docs.termix.site/develop/auth before starting one.
+
+## Testing
+
+```ts
+// vitest.config.ts
+import { pluginVitestConfig } from "@termix-ssh/plugin-sdk/vitest-preset";
+export default pluginVitestConfig(import.meta.url);
+```
+
+Backend tests go in `tests/backend/` (Node), frontend tests in `tests/frontend/` (jsdom). Never next to the
+source.
+
+Backend, from `@termix-ssh/plugin-sdk/testing`:
+
+```ts
+const db = await createTestDb(pluginDir); // in memory SQLite, your migrations, stub users/ssh_data/roles
+let router: Router | null = null;
+const mock = createMockCtx({
+  pluginId: manifest.id,
+  manifest,
+  capabilities: manifest.capabilities, // calls outside these throw, like the real thing
+  db: db.database,
+  router: () => (router = express.Router()),
+  permissions: ["hello.use"], // leave out to allow everything
+});
+await activate(mock.ctx);
+mock.setActor("user-1");
+```
+
+`createMockCtx` also takes `hosts` and `services`. `createFakeContext()` is a looser double that skips the
+capability checks. The template's `tests/backend/routes.test.ts` serves the router with Express and calls
+it with `fetch`: start from it.
+
+Frontend:
+
+```tsx
+import { renderWithApp } from "@termix-ssh/plugin-sdk/testing";
+import * as plugin from "../../src/frontend/index.js";
+
+const app = await renderWithApp(plugin, {
+  api: { get: async () => ({ data: [] }) },
+});
+expect(app.registered.tabs()).toContain("hello");
+```
+
+Test every route, with and without the permission. Test that disable then enable works, and that the plugin
+works when an optional dependency is missing.
+
+## Running it on a server
+
+1. You need Node 24 and a Termix server (26.10 or newer) you are an admin on. A local Docker one is fine.
+2. In Termix, open Settings, General and turn on Plugin developer mode.
+3. Make an API key in Settings, API keys.
+4. Run `npx termix-plugin dev --server http://localhost:30001 --key tmx_...` (or set `TERMIX_SERVER_URL`
+   and `TERMIX_API_KEY`). It builds, installs and reinstalls on every save. Reload the page for frontend
+   changes. `--once` installs once.
+
+Or `npm run build && npm run pack` and install the `.tmxplug` from Plugins, Install from file. Dev installs
+are marked unverified. You can't use the id of a plugin that ships with Termix, and a registry copy of the
+same plugin must be uninstalled first.
+
+## Releasing
+
+Plugins use semver. Work happens on a `dev-X.Y.Z` branch made from `main`, named after the version it will
+ship as. `main` only changes when a stable release merges a dev branch into it.
+
+`CHANGELOG.md`, newest first, no `## Unreleased` section and no dates:
+
+```md
+# Changelog
+
+## 1.1.0
+
+### Added
+
+- A wave button in the terminal toolbar
+
+### Fixed
+
+- Notes keep their order after a restart
+```
+
+Sections: `### Added`, `### Changed`, `### Fixed`, `### Removed`, `### Deprecated`, `### Security`.
+`termix-plugin changelog --version 1.1.0` prints one version's notes.
+
+Run the Release workflow by hand from the dev branch on GitHub:
+
+| Choice    | What it does                                                                      |
+| --------- | --------------------------------------------------------------------------------- |
+| stable    | Tests, builds and publishes `X.Y.Z`, merges the branch into `main` and deletes it |
+| beta      | Publishes `X.Y.Z-beta.N`, N counts up on its own                                  |
+| overwrite | Releases the manifest version again from this commit                              |
+| dry-run   | Builds and packs, publishes nothing                                               |
+
+No secrets are needed. The workflow records GitHub build provenance for the `.tmxplug`, and the run summary
+shows the `sha256` for a registry submission. If a dev branch changes `.github/workflows`, add a
+`TERMIX_PAT` secret (a token with `repo` and `workflow` scopes). To also sign with your own key, set
+`TERMIX_PLUGIN_SIGNING_KEY`. Keep `.github/workflows/release.yml` as the template has it: the community
+registry checks provenance from it.
+
+## Submitting to the community registry
+
+Before you submit:
+
+- The repo is public with an open source license, made from the template or using its `release.yml`.
+- `npm test`, `npm run typecheck`, `npm run validate` and `npm run build` pass.
+- The `id` isn't used by an official plugin or another submission.
+- `name`, `description`, `author`, `repository` (your repo) and `docs` (or a README that explains use) are
+  set.
+
+Then release a stable or beta version and fork https://github.com/Termix-SSH/Termix-Registry. Add
+`community/plugins/<id>.json`:
+
+```json
+{
+  "$schema": "../../community-submission-schema.json",
+  "id": "my-plugin",
+  "repository": "https://github.com/you/termix-plugin-my-plugin",
+  "maintainers": ["your-github-username"],
+  "versions": [
+    { "version": "1.0.0", "sha256": "<from the release run summary>" }
+  ]
+}
+```
+
+Open a pull request. The Check submission job downloads the `v<version>` release and checks the `sha256`,
+that the manifest inside has your id, version and repo, that it has build provenance from the release
+workflow, and that you are a maintainer. Then a person reviews the source at the tag and merges it. The
+registry signs it with the community key and lists it a few minutes later.
+
+Reviewers check that:
+
+- The source does what the name and description say, and nothing else.
+- Nothing is obfuscated or minified, and no code is downloaded and run at runtime.
+- There are no network calls, tracking or telemetry the user didn't ask for.
+- Capabilities and permissions are the fewest needed.
+- `package.json` scripts and dependencies don't fetch or run anything unexpected at install or build.
+- Secrets are only used for what the plugin is for.
+- The name and icon don't pretend to be an official plugin.
+
+Every version needs its own PR that adds it to the top of `versions`. Overwriting a reviewed release drops
+it from the registry until a new version is submitted. Admins see the plugin once they turn on the community
+registry in Plugins, Registries.
+
+To run your own registry instead, see https://docs.termix.site/develop/registries.

+## Common mistakes
+
+- Tests fail after `npm install`: usually a missing devDependency (`@testing-library/dom`, `jsdom`,
+  `better-sqlite3`) or a newer TypeScript major pulled in by another package. Pin `typescript` to the
+  template's range.
+- `hello-world`, `hello_world` or `Hello World` left over from the template in `package.json`, locales,
+  index names, API paths, tab ids or tests.
+- Changed `tables.ts` without running `npm run migrations`, or kept the template's `migrations/` folder
+  after renaming the id. Delete it and run `npm run migrations` once on a fresh plugin.
+- A rail item or tab id that isn't declared in `contributes`.
+- A string typed straight into JSX instead of `t()`.
+- Forgetting `await ctx.db.persist()` after a write.
+- Frontend changes not showing during `dev`: reload the page.
+- An id clash with an official plugin: dev installs and registry submissions are refused.
+
+## Where to look next
+
+- Docs: https://docs.termix.site/develop
+- Official plugins are all open source and built the same way. Plugin-Workspaces is a small one to start
+  from, Plugin-Docker runs commands on hosts, Plugin-Snippets offers a service, Plugin-Automations uses
+  services, Plugin-SSO and Plugin-TOTP add sign in, Plugin-Vault adds an SSH auth type and
+  Plugin-Remote-Desktop adds a protocol. All at https://github.com/Termix-SSH.
+- Help: the Discord at https://discord.gg/jVQGdvHDrf. SDK bugs go in
+  https://github.com/Termix-SSH/Termix/issues.
