-# AGENTS.md — Element Call
-
-MatrixRTC (MSC4143) + LiveKit video calling, shipped standalone, as a widget in
-Element Web and Element X, as embedded packages, and as a React component in a
-host's page. It is the MatrixRTC reference implementation.
-
-## Non-negotiables
-
-- Features and UI changes need a pre-approved issue. No issue, no review.
-- Exactly one `PR-*` label per PR. CI enforces it; it drives the changelog.
-- New behaviour ships with unit tests, a story if it renders, and an e2e spec if it
-  is user-facing. All three.
-- Reuse an existing component. If you genuinely cannot, say so in the PR body and
-  name what you rejected — never add a new one silently.
-- Nothing reads the page. No `window.location`, `document.body`, `window.inner*`,
-  `@media`, global `i18next` or the `widget` global — take it from a provider.
-- The change works standalone, as a widget and as a component. Say what you checked.
-- Every gate below is green before you push.
-- Hand off after the first implementation, before the quality pass. Then commit on
-  the user's word where the setup allows it, or hand them the message.

 # Contributing code to Element
 
 Element follows the same pattern as the [matrix-js-sdk](https://github.com/matrix-org/matrix-js-sdk/blob/develop/CONTRIBUTING.md).
-
-# Contributing to Element Call
-
-Element Call is a native Matrix video conferencing application built on
-[MatrixRTC (MSC4143)](https://github.com/matrix-org/matrix-spec-proposals/pull/4143)
-and [LiveKit](https://livekit.io/). It runs in multiple deployment contexts — as a
-standalone web app and as a widget embedded in Element Web, Element X iOS, and
-Element X Android. It is also the primary R&D foundation for MatrixRTC, which means
-its architecture, maintainability, and flexibility are held to a high standard.
-
-We welcome contributions from the community. This document explains how to
-contribute effectively so that both you and the maintainers get the best outcome.
-
-## Issue First Policy
-
-> [!IMPORTANT]
-> Before writing a single line of code for a new feature or UI change, you **must**
-> open an issue and have the approach agreed with the maintainers.
->
-> **We will not review or merge feature or UI pull requests that arrive without a
-> corresponding, pre-approved issue.**
-
-This is not gatekeeping — it's how we prevent wasted effort on both sides. Element
-Call must work correctly across multiple deployment contexts and meet specific product
-and design requirements. It is also a fast-moving codebase that underpins ongoing
-MatrixRTC development. A PR that looks reasonable in isolation can easily conflict
-with in-progress work, planned architecture changes, or design decisions that haven't
-been publicly documented yet.
-
-The issue is where we resolve all of that **before** anyone writes code.
-
-**Bug fixes** are no exception — most confirmed bugs should already have an issue anyways, existing issues that are marked as bugs have an implicit maintainer approval. If the solution for the bug is controversial it is highly recommended to discuss the approach in the issue before opening a PR.
-
-## Contribution Workflow
-
-1. **Open an issue** using the [Enhancement request](https://github.com/element-hq/element-call/issues/new?template=enhancement.yml) template.
-2. **Wait for feedback.** A maintainer will comment on the issue **within two weeks**. The use case and approach will get dicussed.
-   This may involve questions, suggestions, or a request to adjust scope.
-   This also allows to bring design and product into the loop before code gets created.
-3. **Get a green light.** Wait for explicit approval from a maintainer before starting
-   implementation.
-4. **Implement.** Write the code against the agreed approach.
-5. **Open a PR.** Link to the issue in your PR description and satisfy the checklist
-   in the PR template.
-
-## Code Quality
-
-Element Call moves fast and the codebase must stay clean and maintainable.
-
-- **Take responsibility for AI-generated code.** AI tools can be a useful aid, but we expect all the generated code to be understood and reasoned about by the contributor. Questions by the maintainers should be answered without just forwarding them to AI. The maintainers also have access to AI tools. If your contribution is just transporting messages between LLM <-> maintaines all our time is better used if the maintainers decide to interact with AI for this specific problem by themselves.
-- **Think across deployment contexts.** Changes must work correctly in both standalone
-  and widget modes. Consider how your change interacts with Element Web, Element X
-  iOS, and Element X Android.
-- **Write tests.** New functionality should be covered by tests. Where it is feasible,
-  existing uncovered code touched by your PR should also gain tests.
-
-## Contributor License Agreement
-
-All contributors must sign the
-[Element Contributor License Agreement](https://cla-assistant.io/element-hq/element-call)
-before their contribution can be merged. The CLA assistant bot will prompt you
-automatically when you open a PR.

-#### Element Call as a component (experimental)
-
-Element Call can also be embedded directly into another React application
-rather than being loaded in an iframe as a widget. `pnpm build:component`
-builds it as a library into `component/dist` (the bundle, its stylesheet and
-type declarations), and
-
-```sh
-pnpm dev:component
-```
-
-serves a harness on port 3001 that stands in for such an application: it signs
-in twice against the development backend and shows two calls side by side, in
-resizable boxes, with page furniture of its own around them. Use it to see how
-Element Call behaves when it does not own the page — the size it is given,
-whether it stays inside its container, and what it says to its host, which is
-logged along the bottom. The harness is served with the same development
-certificate as the app, so unless the development CA is trusted, the browser
-needs a certificate exception for `https://localhost:3001` as well (see the
-note under [Backend](#backend)). It reads the same `public/config.json` as
-`pnpm dev` if one exists, and runs with Element Call's defaults otherwise.
-
-The call lays itself out for the size of the element it is mounted in, not the
-window: a host that shrinks the container to a corner of its page gets the
-picture-in-picture layout, just as a host that shrank the whole iframe used to.
-The breakpoints in the stylesheets the component uses are
-`@container element-call` queries against its root element for the same reason;
-for the standalone app the root is the page, so they mean what the media queries
-they replaced did. (The standalone-only views, such as the home and login pages,
-still use plain media queries, since the component never shows them.)
-
-The component's stylesheet is confined to the element it is mounted in: the
-build rewrites every selector so that it matches only Element Call's root or
-what is inside it, with `html`, `body` and `:root` standing for that root (see
-`component/build/scopeStylesToRoot.ts`). A host's own page keeps its styles,
-and Element Call brings its own fonts and design tokens along.
-
-The component speaks every language the app does. English is bundled in; the
-other locales are split into chunks the host's bundler loads the first time
-they are needed. It starts in the browser's language, and follows the host's
-own language setting through the `language` prop (`supportedLanguages` lists
-the tags it accepts, and anything else falls back to its base language or to
-English). The `theme` prop works the same way and takes the same values as the
-widget's `theme` URL parameter: `light`, `dark`, `light-high-contrast` or
-`dark-high-contrast`. Both can change while a call is running without
-disturbing it.
-
-A host must call and await `initializeElementCall(config)` once before
-rendering the component: it loads the `Intl` polyfills, applies the
-deployment-wide `config.json`-style configuration and sets up translations.
-The component itself takes the host's `client` and the `roomId` to call in, an
-`intent` saying what the user asked for (which decides whether to show the
-lobby, ring, and so on), an optional `config` overriding what the intent
-implies, and an optional `hostBridge` through which Element Call tells the host
-that the user has joined or hung up, that it wants to stay on screen, and so
-on. The host makes its own requests (`join`, `hangUp`, `setDeviceMute`) through
-the handle exposed on `ref`. The full API is documented in the type declarations
-(`component/index.tsx` and `component/host.ts`).
-
-A few things differ from the widget on purpose: the component draws a solid
-background rather than a gradient unless told otherwise, never offers to edit
-the user's profile (the account is the host's), scopes its keyboard shortcuts to
-its own root element so that several instances can share a page, and only shows
-its own post-call and error screens when the host has not supplied a `close()`
-callback; with one, it asks the host to unmount it instead. The
-[global JS controls](./docs/controls.md) on `window` are unchanged and remain
-page-wide, so with several instances on one page they apply to all of them.
-
-The package is not published yet. A host installs it as a git dependency on the
-`component` directory of this repository,
-
-```json
-"@element-hq/element-call-component": "github:element-hq/element-call#main&path:/component"
-```
-
-whose `prepare` script runs the build on install. That build needs pnpm (via
-Corepack) on the host's machine, runs a full `pnpm install` of this repository,
-since it inherits the `--max-old-space-size` setting of
-the app build; the host's pnpm also has to allow it to run at all
-(`allowBuilds` in its `pnpm-workspace.yaml`). Note that `component/` is a pnpm
-project of its own for this reason, so pnpm commands run from inside that
-directory target it rather than the repository; run them from the repository
-root. The host imports the component from
-`@element-hq/element-call-component` and the stylesheet from
-`@element-hq/element-call-component/style.css`, and has to provide `react`,
-`react-dom`, `matrix-js-sdk`, `livekit-client`, `@vector-im/compound-web` and
-`@vector-im/compound-design-tokens` itself, since the bundle leaves them
-external. Compound's stylesheet are the host's to load too: the component shares
-the host's copy of Compound, (required for example for tooltips)
-
-The component is large, and a host will usually load it lazily, only once a
-call is shown. Everything a host needs in order to talk about a call before
-then is also exported
-from `@element-hq/element-call-component/api` (a small entry point that does not
-load the component).
-
-- props and the types they are made of
-- the handle
-- the host bridge
-- `UserIntent`
-- `HeaderStyle`
-- `BackgroundStyle` enums
-- `configurationForIntent`, the defaults each intent implies
-  Import from it wherever a value such as
-  `BackgroundStyle.Solid` is needed on a path that must stay light; the main
-  entry point re-exports all of it too.

- * What a host needs in order to talk about Element Call, without Element Call:
- * the component's props and the types they are made of, the handle and the
- * host bridge, the intents a call can be started with and the configuration
- * each implies.
- *
- * This is an entry point of its own, `@element-hq/element-call-component/api`,
- * so that a host can import it on a path that must stay light — a call model
- * that needs `BackgroundStyle.Solid` as a value, say — and load the component
- * itself, and everything it brings, only when a call is shown. The main entry
- * point re-exports all of it, so a host that does not care may import
- * everything from there.
- *
- * Nothing in here may reach anything that is not a type or a constant: the
- * point of this module is what it does not import.

-// that the host's document is left as it was.

-// the theme class it carries, as any element on the host's page would.

-// Where these land relative to the component stylesheets is the bundler's
-// choice — the standalone app puts them first, this build puts them in the
-// middle — so nothing in base.css may depend on winning or losing against a
-// component's own rules at equal specificity. It currently does not: what it

-## Testing on Mobile Devices
-
-When developing Element Call locally, you may want to test on physical mobile devices (iOS/Android)
-on the same WiFi network.
-
-**Known Limitations:** For now this setup allows to use your local EC server but not yet the SFUs and Synapses.
-
-### Prerequisites
-
-1. **Start the dev server**
-
-   ```bash
-   pnpm dev
-   ```
-
-Check the output for the `➜  Network` (this will contain the local IP address of your laptop)
-
-```

-
-2. **Transfer the CA certificate to your phone**
-
-   The file is located at `backend/dev_tls_local-ca.crt`. Transfer it via:
-   - Matrix room
-   - AirDrop for iphone
-
-### IOS Setup
-
-**Install the certificate profile on iPhone**
-
-- Open the `dev_tls_local-ca.crt` file on your iPhone
-- You'll see "Profile Downloaded"
-- Go to **Settings → General → VPN & Device Management** (or **Settings → General → Profiles**)
-- Tap the "Element Call Dev CA" profile
-- Tap **Install** and enter your passcode
-- Confirm by tapping **Install** again
-
-**Enable full trust (Critical!)**
-
-- Go to **Settings → General → About → Certificate Trust Settings**
-- Under "Enable Full Trust for Root Certificates"
-- Toggle **ON** for "Element Call Dev CA"
-- Confirm the security warning
-
-**Access Element Call**
-
-Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Safari to validate:
-
-```
-https://192-168-0-122.nip.io:3000/
-```
-
-**For Element X iOS Developer Tools**
-
-In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
-
-```
-https://192-168-0-122.nip.io:3000/room
-```
-
-### Android Setup
-
-**Transfer the CA certificate to your Android device**
-
-The file is located at `backend/dev_tls_local-ca.crt`.
-
-**Install the certificate**
-
-This might vary by Android version and manufacturer, but generally:
-
-- Open **Settings** search for "CA Certificate"/"Certificate"
-- Tap **Install a certificate** or **Install from storage**
-- Select **CA certificate**
-- Confirm the security warning
-- Navigate to and select the `dev_tls_local-ca.crt` file
-- Give it a name like "Element Call Dev CA"
-
-**Access Element Call**
-
-Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Chrome to validate:
-
-```
-https://192-168-0-122.nip.io:3000/
-```
-
-**For Element X Android Developer Tools**
-
-In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
-
-```
-https://192-168-0-122.nip.io:3000/room
-```
-
-### Why nip.io?
-
-[nip.io](https://nip.io) is a free wildcard DNS service that automatically resolves domain names containing IP addresses. For example, `192-168-0-122.nip.io` automatically resolves to `192.168.0.122`. This means:
-
-- No need to regenerate certificates when your laptop's IP changes
-- Works from any device without DNS configuration
-- iOS/Android treat it as a proper domain name, not an IP address
-- One-time certificate setup works for all future IP addresses
-
-> [!IMPORTANT]
-> Make sure your network router doesn't enforce DNS rebinding protection (which will
-> break nip.io). If it does, try allow-listing nip.io in your router's administration interface.

-  behaviors plus callbacks. Copy `src/state/LayoutSwitchViewModel.ts`. Prefer this
-  for anything new.
-- Owning a resource: a class taking the scope in its constructor — `MediaDevices`,
-  `MuteStates`, `TileStore`, `Publisher`, `Connection`. Both styles are current;
-  don't convert one to the other in passing.
-- `foo$` is an observable. `Behavior<T>`, an observable with a current value, is
-  the default for anything a view reads.
-
-## The view model / view contract
-
-- Components take `vm: ViewModel<Snapshot>` and read state through `useBehavior`.
-  See `CallFooter`, `InCallView`, `LobbyView`, `SettingsModal`.
-- A snapshot is `Actions & State`; every field becomes a `foo$` behavior, and none
-  is optional.
-- An unavailable action is `undefined`, not a separate `canDoThing` flag — the
-  presence of the callback drives the rendering.
-- Subscribe in an effect only to drive a side effect off an event stream, as
-  `ReactionAudioRenderer` does; never to read state a behavior already holds.
-
-## Scopes own lifetimes
-
-- `ObservableScope` bounds every subscription a view model creates.
-- Reference only the scope defined in the same function; one captured from an
-  enclosing scope outlives its owner, and `no-observablescope-leak` rejects it.

-  `AudioOutput`. Intent presets set it on non-desktop; standalone leaves it off.

-- `build:sdk` — SDK library, entry `sdk/main.ts`.
-- `build:component` — `@element-hq/element-call-component`, sources in `component/`
-  (its own pnpm project; run pnpm from the repo root). Host API is in the README;
-  `pnpm lint:externals` rejects an import of a `react` / `react-dom` /
-  `matrix-js-sdk` / `livekit-client` / `@vector-im/compound-web` /
-  `@vector-im/compound-design-tokens` subpath the externals list omits.
-  Compound's stylesheets are loaded by `src/index.css` for the page and by the
-  host for the component, never by `src/base.css`. Two entry
-  points: `index.tsx` (the component) and `api.ts` (types, enums and
-  `configurationForIntent`, for a host that must not load the component). `api.ts`
-  may only reach types and constants — `src/UrlConfiguration.ts`, not `UrlParams`.

-# Code style
-
-_Clean Code_ (Robert C. Martin): small functions, intention-revealing names, low
-noise.
-
-## Reuse before you build
-
-Look before you write, in this order:
-
-1. **Compound Web** — `@vector-im/compound-web` for buttons, tooltips, alerts,
-   dialogs, menus, form controls, avatars; icons in
-   `@vector-im/compound-design-tokens/assets/web/icons`.
-2. **This repo** — `src/button/`, `src/components/`, `src/input/`, `src/form/`,
-   `src/tabs/`, and `Modal`, `Avatar`, `Toast`, `Slider`, `ErrorView`,
-   `FullScreenView` at the root of `src/`.
-3. **The nearest existing feature** — grep for the same shape first. A hook is
-   often what you want to extract, not a component.
-
-If nothing fits, name the new shared component in the PR body and say what you
-rejected and why — never add one silently. Extend or parameterise before forking,
-and extract shared logic into a hook both callers use before copying it; if you
-copy, the PR says so.
-
-## Ordering
-
-- **Newspaper order.** Headline first, detail down. A file opens with what it
-  exists to provide.
-- **Stepdown rule.** Caller above callee. A helper used by one function sits
-  beneath it, which needs a `function` declaration, not a `const` arrow. Existing
-  arrow components above their callers are not a pattern to extend — nor to churn.
-- **Suites.** Test cases first, helpers below. Older suites invert this; follow the
-  rule in new ones, don't reorder old ones.
-- **Names.** What a thing means, not what it is made of: `naturalLayout$`, not
-  `computedLayout$`.
-
-## Comments
-
-No comment is the default. One earns its place by giving a reason the code
-cannot: a platform quirk, an outside constraint, a trap that looks like a
-simplification.
-
-- Say the reason, then stop. Test each sentence: does the reason still stand
-  without it? If so, cut it. Most reasons fit on a line, so a long comment is
-  worth a second look — it is usually carrying something that isn't one.
-- Write about the line the comment sits on, in terms of what the code does
-  there — leave layout to the stylesheet and measurements to the design.
-- Name the condition ("where the platform can't route audio"), not the browser
-  or the spec entry.
-- Put history — what was tried, removed or rejected, the dev journal — in the
-  commit or the PR description.
-- In tests, comment only structure that looks wrong but isn't: batching, timers,
-  why this scroll position.
-
-Before keeping one: would it still be true after a CSS change or a refactor of
-its caller? If not, cut it.
-
-## TypeScript, React and RxJS idiom win on a clash
-
-- Hooks stay unconditional at the top of a component.
-- `useCallback` / `useMemo` dependency arrays sometimes force inlining.
-- An RxJS pipeline stays one expression. Name the behavior, not each operator.
-- A long factory is fine when it reads as a list of named behaviors.
-  `CallViewModel.ts` is long because the domain is.
-- Marble test tables are dense on purpose.
-
-## Enforced by lint
-
-- Copyright header on every file: `Copyright <current year> Element Creations Ltd.`
-  plus the AGPL / commercial SPDX line.
-- `logger` from `matrix-js-sdk/lib/logger`, never `console`, and no top-level
-  `logger.getChild()`. The `console` ban is only enforced under `src/*/**`.
-- No floating or misused promises; async functions typed `Promise<T>`.
-- Inline type imports (`import { type Foo }`), so matrix-js-sdk stays lazily
-  loadable.
-- Deep-import `matrix-js-sdk/lib/<module>` as the codebase does. Banned is the bare
-  `matrix-js-sdk/lib`, `lib/index` and anything under `src/`.
-
-## CSS
-
-- Compound components and `--cpd-*` tokens in CSS modules. A hardcoded colour or px
-  spacing is a design question, not a licence to inline a hex.
-- Size against the root, not the window: `@container element-call (…)` and
-  `cqw` / `cqh`, never `@media (width)` or `vw` / `vh`. Media queries stay correct
-  only in standalone-only views — home, login.
-- Style `[data-element-call-root]`, never `body` or `:root`; the component build
-  makes those stand for the root (`component/build/scopeStylesToRoot.ts`).
-
-## Strings and a11y
-
-- Strings through `t()`: add the key, run `pnpm i18n`, fill `locales/en/app.json`.
-  Other locales come from Localazy; never hand-edit them.
-- `t` from `useTranslation()`, or `src/utils/i18n.ts` outside React. Never the
-  `i18next` global — several instances share a page.
-- Accessible names on controls, `aria-pressed` on toggles, keyboard reachability.
-  `jsx-a11y` rules are errors; `vitest-axe` is available.

-lines a PR touches.

-## Unit
-
-- View model tests use `withTestScheduler` + `testScope()` from `src/utils/test.ts`
-  and read as ASCII timelines. Copy `LayoutSwitchViewModel.test.ts`.
-- Component tests use Testing Library, queried by role and accessible name.

 ## Audio devices
 
 On mobile platforms (iOS, Android), web views do not reliably support selecting audio output devices such as the main speaker, earpiece, or headset. To address this limitation, the following functions allow the hosting application (e.g., Element Web, Element X) to manage audio devices via exposed JavaScript interfaces. These functions must be enabled using the URL parameter `controlledAudioDevices` to take effect.

 # Developing with linked packages
 
-If you want to make changes to a package that Element Call depends on and see those changes applied in real time, you can create a link to a local copy of the package. `pnpm` has a command for this (`pnpm link`), but it's not recommended to use it as it ends up modifying package.json with details specific to your development environment.
+If you want to make changes to a package that Element Call depends on and see those changes applied in real time, you can create a link to a local copy of the package. Yarn has a command for this (`yarn link`), but it's not recommended to use it as it ends up modifying package.json with details specific to your development environment.
 
-Instead, create a file named `.links.cjs` in the Element Call project directory (or run `./scripts/setup-linking.sh` to create a template), listing the names and paths of any dependencies you want to link. For example:
+Instead, you can use our little 'linker' plugin. Create a file named `.links.yaml` in the Element Call project directory, listing the names and paths of any dependencies you want to link. For example:
 
-```cjs
-// Packages to link to local checkouts
-module.exports = {
-  "matrix-js-sdk": "../your/path/matrix-js-sdk",
-  "matrix-widget-api": "../your/path/matrix-widget-api",
-};
+```yaml
+matrix-js-sdk: ../path/to/matrix-js-sdk
+"@vector-im/compound-web": /home/alice/path/to/compound-web
 ```
 
-Then run `pnpm links:on`. (this will activate the pnpm file + run `pnpm install` to setup the linking)
+Then run `yarn install`.
 
 ## Hooks

+One always needs to run:
 
 ```bash
-pnpm install
+mv .links.yaml .links.disabled.yaml

 before committing a change.
 
-To make this less of a foot gun we added a git hook.
-A `pre-commit` hook will check if linking is currently used. If it detects
-a `.pnpmfile.cjs` file it will abort the commit with an explanatory message.
-You will then need to run `pnpm links:off` and commit again.
+To make it more convenient to work with this linking system we added git hooks for your conviniece.
+A `pre-commit` hook will run `mv .links.yaml .links.disabled.yaml`, `yarn` and `git add yarn.lock` if it detects
+a `.links.yaml` file and abort the commit.
+You will than need to check if the resulting changes are appropriate and commit again.
 
-To activate the hooks configure git with (when using the setup script (`./scripts/setup-linking.sh`) this is already done):
+A `post-commit` hook will setup the linking as it was
+before if a `.links.disabled.yaml` is present. It runs `mv .links.disabled.yaml .links.yaml` and `yarn`.
+
+To activate the hooks automatically configure git with
 
 ```bash
-git config --local core.hooksPath .githooks
+git config --local core.hooksPath .githooks/
 ```
-
-This will add the hook path for this repository only to .gihooks. which is a tracked (by git) folder containing the pre-commit hook.

-## Testing against a matrix-js-sdk branch in CI
-
-Linking covers local development. In CI, `scripts/layered.sh` plays the same
-role for `matrix-js-sdk`: after the usual frozen install, `scripts/fetchdep.sh`
-looks for a matrix-js-sdk branch with the same name as the pull request's head
-branch (in the fork first, when the pull request comes from one). If there is
-one, it is cloned, packed and installed over the locked version. If there is
-none, the install stays as `pnpm-lock.yaml` pins it.
-
-This means a change that needs a not yet merged matrix-js-sdk change can be tested
-by giving both branches the same name. This mirrors how element-web tests against
-matrix-js-sdk. Once the matrix-js-sdk branch is merged and deleted, the pull
-request falls back to the lockfile and needs a lockfile bump to stay green,
-which is also what keeps `main` consistent after the merge.

-### Why do we not enable .pnpmfile.cjs by default
-
-Background: The presence of the `.pnpmfile.cjs` adds a field to the `pnpm-lock.yaml` called: `pnpmfileChecksum`. This field is a checksum of the content of the `.pnpmfile.cjs` file.
-`pnpm install --frozen-lockfile` **fails** if there is a `.pnpmfile.cjs` but no `pnpmfileChecksum` or vice versa (or on mismatch).
-
-_TLDR: running with `--ignore-pnpmfile` will fail if `pnpmfileChecksum` is present._
-
-#### `pnpmfileChecksum` + renovate bot
-
-When the renovate bot creates a PR it runs `pnpm install --ignore-pnpmfile`. This means that the `pnpmfileChecksum` in the lockfile will be **empty**.
-This breaks builds that **don't** ignore the `.pnpmfile.cjs`-file. (CI that runs on the renovate PR)
-From here we have two possible paths:
-
-- ignore `.pnpmfile.cjs` in all CI builds (CI will also fail if we accidently add it locally).
-- fixup the `pnpm-lock.yaml` in the renovate PR to contain the correct `pnpmfileChecksum`.
-
-Ignoring in all CI builds means that CI will always fail if we enable the linking system.
-This is annoying but can be worked around with the git hook we provide that at least lets us know that we are
-commiting with enabled linking.
-Only if we remember setting it back/disbale linking (or let ourselves remember by the git hook) the CI will work.
-
-#### Summary
-
-- We will always run into conflicts with the `pnpmfileChecksum` because in renovate prs it will be empty (`--ignore-pnpmfile`)
-- To keep it simple we set `--ignore-pnpmfile` in all of our CI builds to see issues immediately.
-- The only solution is to never have a `.pnpmfile.cjs` in the repository when pushing.
-  - This way there will never be a commit with `pnpmfileChecksum` in the lockfile.
-  - renovate (which uses `--ignore-pnpmfile` which we cannot disable) and other CI will work.
-- We are able to use the linking system locally if we `cp` this file from the scripts folder into `./` on demand.
-- `pnpm links:on` and `pnpm links:off` + `./scripts/setup-linking.sh` will help us with this.

-# MatrixRTC modes
-
-Element Call is in the middle of a transition of how a call session is
-represented: from room _state_ events (`org.matrix.msc3401.call.member`) to
-_sticky_ events
-([MSC4354](https://github.com/matrix-org/matrix-spec-proposals/pull/4354)),
-which are a much better fit for the short lived, per-device nature of call
-memberships.
-
-Not every homeserver supports sticky events yet. The two MatrixRTC modes
-controls whether Element Call uses them.
-
-## The modes
-
-| Mode            | Membership events | SFU selection | JWT endpoint                 |
-| --------------- | ----------------- | ------------- | ---------------------------- |
-| `compatibility` | state events      | multi SFU     | legacy                       |
-| `matrix_2_0`    | sticky events     | multi SFU     | Matrix 2.0 (hashed identity) |
-
-**`compatibility`** — multi SFU, but still state events. Use it when the
-homeserver does not support sticky events. This is the default.
-
-**`matrix_2_0`** — the target state. Requires a homeserver that advertises
-MSC4354 and all clients on v0.17.0 or later. The local membership requests its
-token from the Matrix 2.0 JWT endpoint of the
-[MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)
-and identifies the room by a hashed identity instead of the Matrix `room_id`.
-(Remote memberships always try the new endpoint first and fall back to the
-legacy one, so remote participants can be on either.)
-
-## Selecting a mode
-
-Users can choose a mode under **Settings → Developer → MatrixRTC mode**. The
-Matrix 2.0 option is disabled if the homeserver does not support sticky events.
-
-A deployment can pin the mode for all its clients in `config.json`, which
-disables the Developer Settings choice:
-
-```json
-{
-  "matrix_rtc_mode": "compatibility"
-}
-```
-
-Valid values are `compatibility` and `matrix_2_0`; an invalid value is
-ignored (with a warning) and the user's choice applies. Pinning `matrix_2_0` on a
-homeserver without sticky event support makes joining fail with a "sticky events
-required" error.
