@@ -159,42 +159,13 @@ The reference has two kinds of page:
 
 An overview page answers "what is this API and is it what I need?", and a function page answers "how exactly does this call behave?". A change to one function usually only touches that function's page, so a new `kv.list()` option goes in `KV/list.md` without a matching update to `KV.md`. Don't copy a function's options, limits, or edge cases onto the overview page for completeness. Where a detail goes is a judgment call, not a hard rule: update the overview when a change affects how someone would describe the API as a whole.
 
-When you add a page, add it to [src/docs/src/sidebar.js](src/docs/src/sidebar.js) under its area, or it won't show up in the navigation.
-
-**Sidebar order.** Order the API areas in the sidebar by how often developers use them, most common first. Overview stays first and Objects stays last. Inside an area, order the pages by use too, and keep pages that make up one feature next to each other, such as `share()`, `unshare()`, `listShared()`, and `listSharedByMe()`. A group goes where its most-used page would go. A helper that only supports another function, such as `listModels()` for `chat()`, goes by its own use. Put create, list, get, update, and delete in that order, and constants such as `MAX_KEY_SIZE` last. The function list on the area's overview page uses the sidebar's order. When you add a runnable example, add its HTML to `src/docs/src/playground/examples/<slug>.html`, register the slug in [src/docs/src/examples.js](src/docs/src/examples.js), and link the code block to it by putting the slug after the language with a semicolon (` ```html;kv-set `).
-
-### Function page layout
-
-A function page opens with one sentence that says what the function does, in its own paragraph, such as "Given a prompt, generate an image using AI." Put any more detail in the paragraphs after it.
-
-After the intro, a function page has these `##` sections, in this order:
-
-1. Syntax
-2. Parameters
-3. Return value
-4. Errors, if the function has any
-5. Sections for specific topics, if the page needs them, with `## Model-specific features` last
-6. Examples
-
-[chat.md](src/docs/src/AI/chat.md) follows this layout.
-
-- **Options as a table.** Document an options object as a table with Option, Type, and Description columns. Give each option its own row, even when two options go together, such as `width` and `height`. Order the rows by how often developers use them, most common first, without group rows. In chat.md that's the core options, then reasoning, tools, response handling, request control, and output.
-- **Common options in the table, model-specific behavior in its own section.** A page whose function works with many models or providers, such as [chat.md](src/docs/src/AI/chat.md) and [txt2img.md](src/docs/src/AI/txt2img.md), splits its options this way:
-  - **The options table** under Parameters lists the options that work with every model, and describes each one the way it works for every model.
-  - **`## Model-specific features`**, the last section before Examples, covers everything else. It has a `###` for each model family or provider, named after it, such as "OpenAI models" or "Cloudflare models". Under it go the options only some models accept, and the common options a model handles differently, such as a narrower range, other allowed values, or an option it ignores.
-  - **Write there only what's different.** A `###` lists an option only when that model or provider adds it or handles it differently. An option that works the same everywhere stays out, even if the provider supports it, and a model or provider with nothing different gets no `###`.
-  - **Model-specific features is the only place for model-specific details.** Every limit, format, allowed value, default, price, or quirk that applies to some models goes there, in that model's or provider's `###`, and nowhere else. The options table and topic sections (such as Image inputs or Video input) describe what's true for every model and link to Model-specific features for the rest. Don't add a table or sentence there that compares providers or repeats a model's limits. Each copy is another source of truth to keep in sync, and copies drift when a model changes.
-  - **Link the two.** Directly under the options table, put `Some models accept additional options or handle these options differently. See [Model-specific features](#model-specific-features).` A row whose option behaves differently on some models can also end with `See [Model-specific features](#model-specific-features).`
-- **A long topic gets its own `##` section.** When explaining an option or feature takes more than a sentence or two, such as function calling or output dimensions, give it a section between Errors and Examples and link to it from the options table. This keeps the reference sections short.
-- **Usage patterns are examples.** A way of using the API, such as stopping a stream, goes in a runnable example that the relevant section links to ("See the [stop a stream example](/playground/ai-chat-stop-stream/)."), not in a section of its own.
-- **Each example has a `###` heading** under `## Examples`, so every example shows in the table of contents.
+When you add a page, add it to [src/docs/src/sidebar.js](src/docs/src/sidebar.js) under its area, or it won't show up in the navigation.

 ### Writing docs
 
 These apply to reference pages and recipes alike.
 
 - **Document the developer-facing side only.** The reader is building on top of puter.js, so cover what affects their code: signatures, defaults, return shapes, errors, limits, and behavior they can observe. Leave out internal workings (which service handles the call, storage layout, caching, retries) unless they change what the developer has to do. [rate-limits-and-quotas.md](src/docs/src/rate-limits-and-quotas.md) is the exception: it publishes every limit, including timeouts and caps that come from how the backend works.
-- **Document Puter as it runs on puter.com.** The docs are for developers building on production Puter. Leave out behavior that only happens on a self-hosted or differently configured server, such as a provider that isn't set up there.
 - **Describe the current state.** Docs aren't a changelog. Write how the API behaves now, without "now", "no longer", "existing code is unaffected", or other wording that compares it to an older version.
 - **Verify before you document.** Run the calls you describe against a running Puter instead of inferring behavior from the source.
 - **Write plainly.** Use the literal words a developer would say out loud, with contractions and everyday words. No idioms or figurative verbs ("walk away from something shared with you" → "remove your own access", "nothing to page through" → "without pagination"). No formal register ("present only while more pages remain" → "includes a `cursor` if there are more pages to load"). Prefer dev terms such as atomic, concurrent, and insertion order.
@@ -202,7 +173,6 @@ These apply to reference pages and recipes alike.
 - **Describe behavior directly.** No quoted inner-voice phrases. Write "`isNew` is `true` when the person did not have access before", not "this tells 'I just gave this to someone' from 'they already had it'".
 - **Keep references easy to follow.** Name what a list or code block belongs to in the sentence directly above it. Name a thing once and keep that name. Introduce an actor as "a user" before giving them a role: "A user can create a team. The user who creates the team becomes its owner."
 - **Sentence mechanics.** Never start a sentence with inline code: write "To store data, use the [`set()`](/KV/set/) method." Link every inline mention of an API to its page, every time. No em dashes, and no colons or semicolons mid-sentence; a colon that introduces a code block is fine.
-- **No `##` or `###` headings inside tabs.** The table of contents lists every `##` and `###` heading on the page, including the ones in a hidden tab (an `example-content` block switched by the `example-group` pills), so its links lead to content the reader can't see. Put the heading above the tabs, or use `####` inside a tab, which the table of contents skips.
 - **Show the correct way.** No "don't" and no wrong-way-first examples, in recipes and playground examples alike. Mention a wrong approach only when developers already hit it in practice, and state how it fails as a fact: "`add()` reads a plain object as a path map, so the call rejects with …".

A new window should read like its neighbors: an async function taking an options object, composing an HTML string, wiring behavior with jQuery, delegating to `UIWindow(...)`.
 - **Match the visual language.** Use existing CSS classes (`button`, `button-primary`, window chrome, form styles) and copy the layout patterns of neighboring windows; new styles go in [src/gui/src/css/](src/gui/src/css/) following existing conventions. Verify anything positional (menus, overlays, z-index) on both desktop and mobile viewports.
-- **i18n every user-facing string.** No hardcoded UI text — use `i18n('key')` and add the key to [src/gui/src/i18n/translations/en.js](src/gui/src/i18n/translations/en.js).

 - **Tests.** Vitest is wired for the GUI (`src/**/*.test.js`; see [appOrder.test.js](src/gui/src/UI/Dashboard/appOrder.test.js) for the shape). Extract pure logic into functions and test those. Desktop behavior driven through puter.js (`puter.ui.*`) is covered by the Playwright harness in [src/puter-js/tests/e2e/](src/puter-js/tests/e2e/) — add a spec there when you change how the desktop renders SDK-driven UI.

 - **Worker hot-reload driven by a share recipient.** Sharing a worker's source file with write access is how you let a collaborator change that worker's code and have it deploy live. The redeploy running as the file owner, with the owner's worker credentials, is the intended behavior of that grant — the owner chose to hand out write access to executable code. If you do not want that, do not share the source file with write access.
 - **Re-claiming a site or worker name its owner deleted.** A hosted site or worker name that its owner deletes is treated as abandoned by that owner. If one of their apps still points at it, whoever claims the name next serves that app's `index_url` and receives what the app is launched with, and a new app on the same origin may share the old one's identity. Guarding app identities against being recycled this way is ongoing hardening, not a security boundary, so new ways to re-claim an abandoned name, or to inherit an app's tokens or data through one, are not eligible.
 - **Share-mode downgrades that do not cascade.** Demoting a delegate does not retroactively revoke the grants that delegate already issued downstream. Shares are independent grants once issued, not a live-evaluated chain. Revoking the downstream grant is a separate, supported action.

-# Embedded app browser
-
-`GET /embed/apps` on the deployment's main GUI origin renders the same app browser
-as the dashboard's Apps tab, without the desktop or dashboard navigation.
-
-It supports search, paging, saved folders, and saved ordering. It uses the same
-installed-app and recommendation data as the dashboard, including the user's
-removed recommendations. Editing, adding, reordering, renaming, and uninstalling
-are disabled. Selecting an app opens it in a new browser tab at its own URL, the
-same way the dashboard does, and the host page stays open. The app's token isn't
-put in the URL: the app's SDK asks the embed for it once the tab loads, so the
-embed must still be open then. If the iframe is removed first, the app falls back
-to its normal sign-in. Apps that need the desktop (built-in and godmode apps,
-private apps the user can't open, or a failed token request) open `/app/<name>`
-on the GUI origin, cut off from the embed. Website shortcuts open their external
-destination with no opener.
-The embed follows the OS's light or dark setting. A host with a fixed theme adds
-`theme=dark` or `theme=light` to the fragment (`#user=<uuid>&theme=dark`), since
-Chromium doesn't pass an iframe's `color-scheme` on to the page inside it.
-Apps opened from the embed carry `utm_source=puter.com&utm_medium=referral&utm_campaign=app_browser_embed`;
-the desktop and dashboard send `utm_campaign=desktop` and `utm_campaign=dashboard`.
-
-## Session and framing
-
-The embed shows the GUI session only to the user the host page is signed in as.
-The host names that user's `uuid` (from `puter.auth.getUser()`) in the iframe
-URL's fragment, as `/embed/apps#user=<uuid>`. The embed reads the session, asks
-`/whoami` which user it belongs to, and shows the signed-out view unless the two
-match. So a host that names no user, a malformed one, or a user other than the
-session's, gets the signed-out view, and so does a session the API refuses. A
-failed `/whoami` check shows the error state. The fragment never reaches the
-server and can only narrow what the embed shows: naming the session's own user
-gives the same view as a direct visit to the GUI. Changing the fragment of a
-loaded embed reloads it.
-
-The embed reads the existing GUI session from local storage on its own origin.
-If that storage holds no session, the embed gets the session from the GUI origin's session cookie through
-`/get-gui-token`. This matters in Safari, which gives a framed origin separate
-local storage under each top-level origin, so even a sibling subdomain's iframe
-can't see the GUI's stored token. The session cookie is still sent, because the
-host is on the same site. The embed doesn't write that token back to storage. It
-does not create accounts, show a login dialog, or accept a token from its parent.
-Being signed in on a subdomain alone does not create a session on the main GUI
-origin.
-
-Without a session it can show, the embed shows the recommended apps (`RecommendedAppsService`)
-that the server put in the page, and nothing else: no installed apps, folders, or
-saved order, and no puter.js. Selecting one opens it at the same URL a signed-in
-launch uses, with no opener and no token on offer, so the app signs in on its own.
-Apps that need the desktop open `/app/<name>`. If the page carries no recommended
-apps, or a load fails, the embed displays an unavailable/error state.
-
-The route's `Content-Security-Policy: frame-ancestors` allows the GUI origin and
-the embedding page's origin when it is exactly one label under `config.domain`
-with the scheme and port from `config.origin`. Subdomains the server answers
-itself (`api`, `dav`, `js`, `www`, the native-app hosts, and the host of
-`api_base_url`) and the user-content hosting domains (`static_hosting_domain`,
-`private_app_hosting_domain`, and their `_alt` variants) are refused. For
-example, `https://puter.com` permits `https://spreadsheet.puter.com` but not
-`https://api.puter.com`, and `http://puter.localhost:4100` permits
-`http://spreadsheet.puter.localhost:4100` but not
-`http://someone.site.puter.localhost:4100`. The embedding page is read from the
-iframe request's referrer, so the host must not suppress it (the browser default
-`strict-origin-when-cross-origin` is enough). All ancestors in a nested iframe
-chain must be allowed. Other GUI routes retain `X-Frame-Options: SAMEORIGIN`.
-
-The embed accepts no query parameters. Requests with a query string redirect to
-the same embed path so SDK bootstrap parameters cannot override the session or API
-origin. The host needs to allow the GUI origin in its own `frame-src` CSP if it
-sets one. If sandboxing the iframe, allow scripts, same-origin storage, popups,
-and popups to escape the sandbox.
-
-## Host integration
-
-A first-party app that signs in with puter.js can place `<puter-user-menu>` from
-the SDK in its header instead (see `src/puter-js/src/ui/components.md`). It opens
-this embed with the signed-in user named and closes it when the app's sign-in
-changes. The rest of this section is for a host that builds the iframe itself.
-
-The iframe can be shown whether or not the user is signed in. Create it when
-“More apps” is opened, naming the signed-in user in its fragment, and remove it
-on close so reopening loads current apps and preferences. Remove it when the
-host's own sign-in changes too, such as on sign-out, so an open embed doesn't
-keep the previous user. The host owns the modal and close control;
-there is no parent messaging API and no app list or credential is sent to it.
-The app browser fills its iframe and responds to its size. It shows a spinner until its apps load.
-
-This example assumes `puterOrigin` comes from the host app's deployment
-settings. Translate the button and frame labels using the host app's
-localization system.
-
-```html
-<button id="more-apps" type="button">More apps</button>
-<dialog id="apps-dialog" aria-label="More apps">
-  <button id="close-apps" type="button">Close</button>
-  <div id="apps-frame"></div>
-</dialog>
-<style>
-  #apps-dialog { padding: 12px; width: min(900px, 90vw); }
-  #apps-frame iframe { width: 100%; height: min(650px, 75vh); border: 0; }
-</style>
-<script type="module">
-  const puterOrigin = 'https://puter.com'; // Use this deployment's configured origin.
-  const dialog = document.querySelector('#apps-dialog');
-  const container = document.querySelector('#apps-frame');
-  const trigger = document.querySelector('#more-apps');
-
-  trigger.addEventListener('click', async () => {
-    const url = new URL('/embed/apps', puterOrigin);
-    // Signed out, the embed shows the recommended apps.
-    const user = puter.auth.isSignedIn() ? await puter.auth.getUser().catch(() => null) : null;
-    if (user) url.hash = `user=${encodeURIComponent(user.uuid)}`;
-    const frame = document.createElement('iframe');
-    frame.title = 'Your apps';
-    frame.src = url.href;
-    container.replaceChildren(frame);
-    dialog.showModal();
-  });
-  document.querySelector('#close-apps').addEventListener('click', () => dialog.close());
-  dialog.addEventListener('close', () => {
-    container.replaceChildren();
-    trigger.focus();
-  });
-</script>
-```
-
-## Implementation
-
-`createAppBrowser` in `src/gui/src/UI/Dashboard/AppBrowser.js` owns the shared UI
-and data behavior; its `guestApps` option is the signed-out list. `TabApps.js`
-injects desktop actions. `appsEmbed.js` supplies new-tab launching through
-`launchAppInTab` (signed in) and `guestAppLaunchUrl` (signed out) in
-`src/gui/src/helpers/appTabLaunch.js`, which build the same app URL as
-`launch_app`, and loads only the embed entry, its SDK, and shared styles. `embedHostUser` in
-`src/gui/src/helpers/embedHostUser.js` reads the host's user from the fragment, and
-`embedHostTheme.js` beside it applies the host's theme.
-The normal GUI webpack build emits `bundle.min.js`, `apps-embed.min.js`, and `feedback-embed.min.js`.
-The `/embed/apps` route puts the recommended list in the page's config as
-`guestApps`. No puter.js API or app-list endpoint changes are needed.
-
-## Feedback dialog
-
-`GET /embed/feedback` is the app feedback dialog (`puter.ui.showFeedbackDialog()`)
-for a first-party page, with the same framing rules, query redirect, and
-host-user binding as `/embed/apps`. It sends the feedback for the framing
-page's origin, which the server reads from the referrer and pins with
-`frame-ancestors`; opened top-level, it does nothing. Its page is transparent
-so the dialog's own scrim covers the host.
-
-puter.js uses it on a page one label under the GUI origin, other than the
-subdomains the server refuses, when the page is signed in, framing it in a
-modal `<dialog>` that stays hidden until the embed is ready. A session check that takes longer than 200ms shows a loading scrim
-with a spinner in its place; Escape or a click on it cancels. The embed posts `{ msg: 'feedbackEmbed', state }` to its parent
-(`loading`, then `ready` or `unavailable`) and finally
-`{ msg: 'feedbackDialogClosed', sent }`. It reports `unavailable` without the
-named user's session, or while that user's email still needs confirming, and
-puter.js then uses the `/action/send-feedback` popup, which can sign in. So does
-a frame that never answers, such as one the host's CSP blocks. `feedbackEmbed.js`
-is the entry, sharing `embedSession` in `src/gui/src/helpers/embedSession.js`
-with the app browser; `showFeedbackEmbed` in `src/puter-js/src/lib/guiEmbed.js`
-is the host side.
-
-## Sign-in and file pickers
-
-`GET /embed/sign-in`, `/embed/show-open-file-picker`, `/embed/show-save-file-picker`
-and `/embed/show-directory-picker` serve the same GUI popups as `/action/<action>`
-for a first-party page, with the same framing rules, query redirect, and
-`no-store` as `/embed/apps`. Any other spelling of the path (another case, a
-trailing slash) redirects to it, since the shell boots the desktop for it. They render the normal GUI shell, which names the
-framing page (read from the referrer, pinned with `frame-ancestors`) as
-`gui_params.embed_host_origin`. The GUI then runs the popup boot unchanged, with
-the framing page as `window.opener`, and `window.close()` asks the page to
-remove the frame (`src/gui/src/helpers/popupFrame.js`). Without a framing page
-to answer (opened top-level, or framed by a refused page) it does nothing. The
-popup's parameters come from the fragment instead of the query: `msg_id`,
-`options` and `request_auth`, plus `user` for a picker.
-
-The frame posts `{ msg: 'puterPopupFrame', state }` to its parent: `loading` as
-soon as the shell boots, `ready` once it shows a window or dialog, `unavailable`
-when the page has to use the popup, `provider` when the user picks a sign-in
-provider (below), and `closed` where a popup would close. Its
-answers (`puter.token`, `fileOpenPicked`, `directoryPicked`, `fileSaved`, the
-cancel messages, `sendMeFileData`) are the popup's.
-
-puter.js uses them on a page one label under the GUI origin, other than the
-subdomains the server refuses, unless the page is cross-origin isolated or in a
-frame of another site (which `frame-ancestors` refuses too).
-`showPopupFrame` in `src/puter-js/src/lib/guiEmbed.js` shows the frame in a box
-the size of the popup window, over a scrim, hidden until `ready` and behind the
-loading spinner after 200ms. Escape closes it, on the page or in the frame. One shows per popup, as each
-popup has its own window name: a second picker request of the same kind
-replaces the one showing, and a `signIn()` call made while a framed sign-in is
-open settles with it. On
-screens up to 600px wide the box fills the screen. A frame that is refused,
-never answers, or reports `unavailable` falls back to the popup, opened through
-a consent dialog when the click that asked for it has expired. A reload or navigation the frame
-starts itself (logging out, a sign-out in another tab) names the frame as its
-referrer, so the server refuses it; the page then shows its spinner and opens
-the frame again, once per `ready`.
-
-- **Sign-in** (`puter.auth.signIn()`) has no host-user binding: it is how the
-  page gets a user. The box has a close button, which rejects with
-  `auth_window_closed` as closing the popup does. Providers refuse to be
-  framed, so choosing one posts `{ state: 'provider', url }` with the
-  provider's start URL for this sign-in's `msg_id`, then `unavailable`. The
-  page opens the popup straight at that URL, once it checks the URL is the
-  GUI's `/auth/oidc/<provider>/start` for this `msg_id`, and the provider
-  returns it as this sign-in's popup. `attempt_temp_user_creation` keeps the popup, since
-  only the popup creates a temporary account.
-- **Pickers** frame only for a signed-in page. The GUI reports `unavailable`
-  unless its session belongs to the user named in `user`, and the page then uses
-  the popup, which can sign in and switch accounts. The token the GUI sends
-  before a picker's answer isn't adopted, since it is for the page's own user.
-  Dismissing the loading scrim settles the picker as cancelled.
-
-## Upgrade
-
-`GET /embed/upgrade` is the deployment's upgrade dialog for a first-party page,
-served like the popups above: the GUI shell with the same framing rules, query
-redirect, exact-path redirect and `no-store`, naming the framing page as
-`gui_params.embed_host_origin`. It runs only when framed by an allowed page.
-
-puter.js frames it on a signed-in first-party page (the same pages as the
-pickers) for `puter.ui.requestUpgrade(details)`, and for the Upgrade button of
-the usage limit dialog a refused call shows there. Elsewhere both keep their
-behavior: inside an app `requestUpgrade()` asks the desktop, and on any other
-page the usage limit dialog opens the dashboard's upgrade page in a new tab.
-
-The frame covers the page with no box or close button, and the GUI page is
-transparent (`html.popup-frame-transparent`) so the dialog's own scrim covers
-the host. The frame allows `payment` as well as `otp-credentials`. Escape on the
-page is left to the dialog, since one there shouldn't drop a payment in
-progress. Its fragment names `user` (the page's signed-in user) and, when the
-refusal gave them, `reason` (`funds`, `subscription` or `storage`) and `method`.
-
-The GUI reports `unavailable` unless its session belongs to `user`, the account
-has no verification or password change waiting (which the frame couldn't be
-closed from), and the deployment defines `window.UIUpgradeAccount` with
-`UIUpgradeAccount.embeddable === true`. Otherwise it runs:
-
-```js
-new UIUpgradeAccount({ attribution: { appUid, reason, method }, onClose }).open_as_window();
-```
-
-`appUid` is the app the framing page's origin resolves to, never one the
-fragment names. `open_as_window()` resolves once the dialog shows, and the GUI
-then posts `ready`. While the page still hides the frame, which Chromium and
-WebKit lay out at 0x0, the GUI posts `ready` first and opens the dialog once
-the frame has a viewport, so a window it opens doesn't center on 0x0.
-`onClose({ upgraded })` must run exactly once, when the
-dialog closes or when it declines to open for the account; the GUI then posts
-`{ msg: 'puterPopupFrame', state: 'closed', upgraded }` and the page removes
-the frame. If `open_as_window()` rejects, the GUI posts `unavailable` instead. `requestUpgrade()` resolves `{ upgraded }`. A call made while the
-frame shows settles with it rather than replacing it, and a call refused while
-it shows still rejects but opens no usage limit dialog over it.
-
-When the frame can't show the upgrade (refused, never ready, `unavailable`, or
-no user to name), puter.js opens the dashboard's upgrade page in a new tab with
-what was refused, through a consent dialog when the click has expired or the
-tab is blocked, and `requestUpgrade()` resolves `{ upgraded: false }`.
-
-## Top-up
-
-`GET /embed/top-up` is the deployment's top-up dialog, where a user with a plan
-buys add-on credit, served and framed like the upgrade: a transparent GUI page
-covering the host with no box or close button, allowing `payment` and
-`otp-credentials`, with Escape left to the dialog. Its fragment names `user`.
-
-puter.js frames it for the **Add credits** item of `<puter-user-menu>`, which
-shows only when whoami reports `subscribed: true` and no `team` paying for the
-account. On a page that can't frame the GUI, the item opens the dashboard with
-`?topup=` in a new tab instead.
-
-The GUI reports `unavailable` unless its session belongs to `user`, the account
-has no verification or password change waiting, and the deployment defines
-`window.UITopUp` with `UITopUp.embeddable === true`. Otherwise it runs:
-
-```js
-new UITopUp({ onClose }).open();
-```
-
-`open()` resolves once the dialog has loaded the account and shows what it can
-buy, and `onClose({ toppedUp })` must run exactly once, when the dialog closes
-or when it declines to open for the account. The GUI then posts `{ msg: 'puterPopupFrame', state: 'closed', toppedUp }`
-and the page removes the frame. When the frame can't show the top-up, puter.js
-opens the dashboard's top-up in a new tab, as it does the upgrade.
-
-While the top-up shows, a call refused for funds still rejects but opens no
-usage limit dialog over it, and `requestUpgrade()` frames nothing over it: it
-resolves `{ upgraded: false }` once the top-up closes.
-
-## Email confirmation
-
-`GET /embed/request-email-confirmation` walks a first-party page's user through
-confirming their email, served like the upgrade: the GUI shell with the same
-framing rules, redirects and `no-store`, run only when framed by an allowed
-page. puter.js frames it on a signed-in first-party page for
-`puter.ui.requestEmailConfirmation()`. Inside an app the desktop shows the same
-windows over the app instead.
-
-Like the upgrade, the frame covers the page with no box or close button, over a
-transparent GUI page, and its fragment names `user`. Escape closes it, on the
-page or on the save-account or code window. On a window, Escape closes that
-window as its close button does, so a code already sent still answers. The GUI
-reports `unavailable` unless its session belongs to `user` and the account has
-no phone, card or password check waiting.
-An email check is fine: the boot skips its own email gate for this action, so
-the user gets one code window they can close.
-
-The GUI then runs `ensureConfirmedEmail` (`src/gui/src/helpers/ensureConfirmedEmail.js`),
-which the desktop's handler uses too: a temporary account gets the save-account
-window first, then an unconfirmed email gets the code window, each at most
-once. When the page's whoami already reads the email as confirmed,
-`requestEmailConfirmation()` resolves `{ response: true }` without framing
-anything, and a confirmation in the frame marks that whoami confirmed for the
-calls after it. An email the GUI reads as confirmed shows nothing. Before
-opening a window the GUI waits for the frame to have a viewport, as the upgrade
-does. It then posts
-`{ msg: 'puterPopupFrame', state: 'closed', confirmed }`, and
-`requestEmailConfirmation()` resolves `{ response: confirmed }`, the field an
-app reads from the desktop's answer. A call made while the frame shows settles
-with it. A frame that is refused, never ready, or `unavailable` resolves
-`{ response: false }`, since there's no popup to fall back to.
-
-## Custom domains
-
-`GET /embed/attach-custom-domain` is the custom domain dialog of
-`puter.hosting.attach()`, the popup at `/action/attach-custom-domain`, served
-like the upgrade: the GUI shell with the same framing rules, redirects and
-`no-store`, run only when framed by an allowed page. puter.js frames it on a
-signed-in first-party page (the same pages as the pickers).
-
-The frame covers the page with no box or close button, over a transparent GUI
-page, so the dialog floats over the host with its own scrim as it does on the
-desktop. The frame allows `clipboard-write`, for the dialog's copy buttons, as
-well as `otp-credentials`. Escape on the page is left to the dialog, which
-doesn't close while a request is in flight. Its fragment names `user` (the
-page's signed-in user), `subdomain` (the site to attach a domain to) and
-`msg_id`.
-
-The GUI reports `unavailable` unless its session belongs to `user` and the
-account has no verification or password change waiting. It then runs the
-popup's action unchanged, with the framing page as the requester the dialog
-names: it posts `ready` once the dialog is on the page, answers
-`{ msg: 'customDomainAttached', domain, original_msg_id }` once the dialog has
-closed and its exit has played, and then posts `closed`. `domain` is the domain the user chose, or
-null. `attach()` resolves it. A frame that closes without an answer, or a
-loading scrim the user dismisses, resolves null.
-
-A call made while the frame shows resolves null without replacing it, as a
-second call does on the desktop. A frame that is refused, never ready, or
-`unavailable` falls back to the popup, which can sign in, through a consent
-dialog when the click has expired.
-
-## Checks
-
-Run the GUI component/browser tests (with the SDK bundle built and Playwright
-Chromium installed), and the backend route tests:

-# Browser push client
-
-Puter's desktop shows pushes through `/sw.js`. Core shows Settings → Notifications only when the `pushEnabled` gui param is `true`; core never sets it. The worker is registered only when push is turned on in the browser, and a load removes one left without a subscription. A backend extension that delivers pushes sets it with `services.homepage.setGuiParam('pushEnabled', true)` and can load its own code into the worker with `services.homepage.registerServiceWorkerScript(path)`.
-
-Core subscribes the browser to a push service only when the server also publishes `pushWebPushKey` (see [Built-in Web Push client](#built-in-web-push-client)), and it has no `/push/*` routes of its own. The device, app, preference and subscription endpoints below come from that extension. On a deployment without one, such as most self-hosted servers, they answer core's plain 404 (`code: 'not_found'`), which `puter.notifications` reports as `push_unavailable` and the Notifications tab shows as unavailable. A device the extension can't find is `device_not_found`.
-
-## Push payload
-
-`sw.js` reads the push's JSON body. The message is its `puter` field, or `data.puter` for services that only carry string data, as an object or a JSON string:
-
-```ts
-{ uid?: string; title?: string; body?: string; icon?: string; group?: string;
-  target?: { app?: string; path?: string }; data?: unknown; channel?: string;
-  type?: 'challenge'; challenge?: string }
-```
-
-`uid` is the notification's uid, a later push with the same `group` replaces the one showing, and `target` and `data` reach the app when the user taps it.
-
-When the browser replaces the subscription (`pushsubscriptionchange`), `sw.js` posts `{ type: 'puter-push-subscription-changed' }` to every open window on Puter's origin. The worker has no token or session, so the page's push client registers the new subscription.
-
-## Receipts
-
-Before a notification is pushed, the server asks the open clients whether they received it live. It sends `notif.receipt` with `{ uid }` on the user's sockets for the app that sent it, or on the desktop's sockets for Puter's own notifications. The SDK remembers the uids its page received through `onNotification()`, `onPush()` or the desktop's feed, and answers once its page has that notification, or with `{ received: false }` when it never gets it. The server waits up to 5 seconds (`notificationAckTimeoutMs`).
-
-An answer carries `visibilityState` and `focused` as they were when the page received the notification. Pages never show a browser notification themselves; pushes do.
-
-- An answer from a page that was visible and focused stops the push (`handled` on `notif.delivery.settled`). An older client that doesn't send `focused` counts while visible.
-- Otherwise the notification is pushed, to every browser the user subscribed. A website's pushes go only to the browsers that subscribed through its own worker, never to Puter's `/sw.js`. An app inside the desktop pushes through `/sw.js`, which shows the app's name and icon.
-- A client that can't answer, such as an older puter.js, doesn't hold the push back.
-
-The ask reaches only the sockets in the asking region. So that other regions hear about a page too, a page that receives a notification live while visible and focused also sends `notif.handled` with `{ uid }` on the socket it came on. Core relays it as the node-local `notif.handled` event with the socket's user and app, at most 60 a minute per user; an extension that delivers pushes decides what to do with it.
-
-## Registering
-
-The registry is in [src/gui/src/helpers/pushClient.js](../src/gui/src/helpers/pushClient.js). A service script registers its client like this:
-
-```js
-service_script(async (api) => {
-    api.use()['push.registerPushClient']?.(client);
-});
-```
-
-`use(id)` throws when nothing is registered under `id`, so the form above also runs on a Puter version without the registry and does nothing there. Any script that runs after the GUI bundle can call `use()['push.registerPushClient']?.(client)` the same way. Registering again replaces the client. Registering dispatches `push-client-registered` on `window`, and an open Notifications tab redraws.
-
-With no client registered, the tab says push notifications aren't available in this browser.
-
-### Built-in Web Push client
-
-When the server also sets the `pushWebPushKey` gui param (a VAPID public key), core registers its own client ([webPushClient.js](../src/gui/src/helpers/webPushClient.js)) unless an extension registered one first. It uses `puter.notifications.enable()` / `disable()`, the same standard Web Push flow apps use on their own origins:
-
-1. `GET /push/web/key` for the key, then `pushManager.subscribe()` on the `/sw.js` registration.
-2. `POST /push/web/subscriptions { subscription }`. A subscription the server already has answers `{ status: 'active' }`. A new one answers `{ status: 'pending' }`, and the server sends it a push with `{ type: 'challenge', challenge }`.
-3. The worker shows that push and posts `{ type: 'puter-push-challenge', challenge }` to the origin's windows; the page sends it to `POST /push/web/subscriptions/verify`. The device is registered once the page hands the confirmation back.
-4. `DELETE /push/web/subscriptions { endpoint }` removes it.
-
-Apps on their own origin do the same through `push-sw.js`, which they import into their own worker. A subscription made with an app token is the app's: its pushes are that app's notifications only.
-
-## Interface
-
-```ts
-interface PushClient {
-    enable(): Promise<{ deviceUid: string }>;
-    disable(): Promise<void>;
-    status(): Promise<{
-        permission: 'default' | 'granted' | 'denied';
-        registered: boolean;
-        deviceUid?: string;
-    }>;
-}
-```
-
-- `enable()` may ask for notification permission, so core calls it from a click: Turn on in the Notifications tab, Allow on a permission prompt that includes `notifications:push` while this browser is off, and the "Turn on notifications" button of the `/action/enable-push` popup and the matching desktop dialog (`UIEnablePushDialog`). Core also calls it without a click, from `helpers/pushSync.js`, when `Notification.permission` is already `granted`, `status()` reports the browser as not registered, the user has not turned push off in this browser, and an app holds `notifications:push`; the browser does not prompt then. The built-in client runs `puter.notifications.enable()`, which subscribes with the `/sw.js` registration and registers the browser through the Web Push flow above (`platform: 'webpush'`). It then resolves the `uid` of this browser's `webpush` device from `listDevices()`. It rejects when permission is refused or the browser wasn't registered.
-- `disable()` runs `puter.notifications.disable()`, which sends `DELETE /push/web/subscriptions { endpoint }` and ends the browser's subscription. The tab calls it for Turn off, and for Remove on the device marked as this browser. Remove on any other device is `DELETE /push/devices/:uid`.
-- `status()` reports the state without prompting. `permission` is `Notification.permission`. `registered` is true when this browser has a device registered for the signed-in user, and `deviceUid` is that device's `uid`.
-
-After `enable()` resolves, the tab calls `POST /push/devices/:uid/test` and asks the user whether a notification showed up.
-
-The tab also reads `GET /push/apps` and `GET`/`POST /push/preferences`.
-
-Core keeps its own record of a browser the user turned off, `puter.push.browser-off:<user uuid>` in `localStorage`, written by Turn off and by Remove on this browser's device, and cleared when `enable()` resolves. The silent registration above skips a browser with that record, so a device removed here stays removed while one removed from another device, or a new sign-in in a browser that already allows notifications, registers again.

-- **Docker** with the `compose` plugin. This is the one thing you have to install
-  yourself — the installer checks for it and stops with an explanation rather
-  than installing it for you.
-  - **macOS / Windows:** [Docker Desktop](https://docs.docker.com/get-docker/).
-    Both ship the `compose` plugin.
-  - **Linux:** [Docker Engine](https://docs.docker.com/engine/install/) plus the
-    [`docker-compose-plugin`](https://docs.docker.com/compose/install/) package.
-  - Confirm before running anything else: `docker compose version` should print a
-    version, not `command not found`.
-  - If Docker is installed but the shell can't see it, make sure your user is in
-    the `docker` group (Linux) or that Docker Desktop is actually running.
+- **Docker** with the `compose` plugin.
 - A **domain** with DNS access — you need a wildcard record (`*.your-domain.com` → server IP). Puter routes by subdomain (`api.<domain>`, `site.<domain>`, `app.<domain>`).
 - Optional: **TLS certs** (or `certbot` to grab them — see Step 3).

 ## Troubleshooting
 
-**`missing required command: docker` — the installer stops immediately.**
-Docker isn't on your `PATH` yet. Puter self-hosting is a Docker Compose stack, so
-nothing can run without it. Install [Docker Desktop](https://docs.docker.com/get-docker/)
-on macOS/Windows or [Docker Engine](https://docs.docker.com/engine/install/) plus
-`docker-compose-plugin` on Linux, then confirm `docker compose version` works in
-the same shell and re-run the installer. On Linux, a fresh Docker install usually
-needs a new login session before your user picks up the `docker` group.
-
 **Site loads but I get a 502 / "Bad Gateway" from Caddy.**
 The puter container failed to come up. `docker compose logs puter` will tell you which dependency rejected it (most often DB password mismatch between `.env` and `config.json`).
