Patch for v0.7: Send a 'close' action when the widget is ready to close

This is a watered-down version of the changes in 832a5aaf57 which should be suitable as a patch to the v0.7 release series. It makes Element Call widgets send a 'close' action in addition to the original 'hangup' action, and nothing more.

The point is that we can then deploy this change to call.element.io with little effort so that clients are more immediately free to expect a 'close' action from Element Call (and thus we unblock https://github.com/element-hq/element-call/issues/2955 and https://github.com/element-hq/element-web/issues/29196).

-            ```
-
-            ### Android AAR
-
-            ```
-            dependencies {
-              implementation 'io.element.android:element-call-embedded:${{ needs.publish_android.outputs.ARTIFACT_VERSION }}'
-            }
-            ```

 # 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.
-
-## Getting Help
-
-The best place to ask questions about Element Call development is the MatrixRTC room:
-
-**[#matrixRtc:matrix.org](https://matrix.to/#/#matrixrtc:matrix.org)**

-# FEATURE_SPEC — Agent Instructions
-
-This folder holds **feature specs distilled from experiments**. A spec is the durable
-artifact of an exploration; the exploration branch is not. Each spec must contain
-enough information for an agent to produce mergeable PRs against a *current* `main`
-without access to the original branch.
-
-## What this folder is not
-
-- Not a design-doc archive. Specs that are not intended to be implemented do not
-  belong here.
-- Not a place for narrative. Prose that does not constrain the implementation or its
-  verification should be cut.
-- Not a substitute for the PR description. The spec explains *why* and *what must be
-  true*; the PR explains *this diff*.
-
-## File naming
-
-`YYYY-MM_Snake_Case_Title.md` — e.g. `2026-09_Raise_Hand_Improvements.md`
-
-The filename is immutable once committed. Renames break links from PRs, issues and
-the drift log. If scope changes fundamentally, write a new spec and set
-`supersedes:` / `superseded_by:`.
-
-A sidecar `YYYY-MM_Snake_Case_Title.product.md` holds the product spec — user stories,
-functional requirements, success criteria. Copy `_TEMPLATE.product.md`. Product owns
-it; see "Brainstorming: the product spec".
-
-An optional sidecar `YYYY-MM_Snake_Case_Title.notes.md` holds lessons learned,
-narrative, dead-end logs and anything else that is worth keeping but does not
-constrain the implementation. Rules:
-
-- The sidecar is **never load-bearing**. Agents do not read it to derive
-  implementation, and nothing in it may contradict or extend the spec. If a note
-  constrains the work, it belongs in `## Decisions`, `## Rejected alternatives` or
-  `## Measurements` instead.
-- Agents may append to it (an observation from a drift check, a wrong turn during
-  implementation) and must never rewrite or delete existing content.
-- An agent that is `blocked` may read the sidecar to draft an open question, but
-  quotes what it found rather than acting on it.
-- No sidecar is required. An empty one is worse than none.
-
-## Style: facts only
-
-Applies to the spec file only. The product spec is prose by design and the notes
-sidecar is unconstrained. The spec is re-read on every regeneration, where prose costs context
-and dilutes the contract, so:
-
-- Bullets, not paragraphs. Declarative present tense. No motivation, no background,
-  no summary of what the code currently does beyond locating the change.
-- Name things instead of describing them — a path, a symbol, an event type, a command,
-  an event id. A reference is shorter and more precise than a sentence about it. Which
-  kind of reference is allowed depends on the section; see "Reference durability".
-- One line per decision plus at most one sentence of rationale. If the rationale needs
-  more, the extra goes in the sidecar.
-- No judgement adjectives (clean, elegant, proper, obviously) and no hedging (should
-  probably, might be nice). Either it is a constraint or it is not in the spec.
-- `## Problem` is at most five bullets.
-- Target under 200 lines for the whole spec; over 300 lines, split the feature or move
-  material to the sidecar.
-
-The test for any line: does it constrain the implementation, constrain its
-verification, or record a measured fact? If not, delete it or move it to the sidecar.
-
-## Reference durability
-
-The spec must stay implementable against a `main` nobody has seen yet, so which
-references are allowed depends on how fast they rot. Most to least durable:
-
-1. Protocol identifiers — `m.reaction`, `m.call.member`, `m.relates_to`, a reaction
-   key. MSC-bound; effectively permanent.
-2. Observable behaviour. Permanent.
-3. Concept names — membership, participation, session.
-4. Test names. Survive file moves and renames, because the test moves with the code.
-5. Exported symbols. Survive refactors sometimes.
-6. File paths. Rot fast.
-7. Line numbers. Never.
-
-Per section:
-
-- `## Problem`, `## Measurements`, `## Slicing plan`, `## Drift log` — any reference,
-  paths and internal symbols included. These describe the codebase **as of `base`**. A
-  reference going stale here is a finding for the drift check, not a defect, and
-  removing the concrete references would leave the drift check with nothing to verify.
-- `## Decisions`, `## Acceptance criteria` — levels 1 to 4 only. No file paths, no
-  internal symbols. This is the part that has to hold against a future `main`.
-- An acceptance criterion that is not user-observable is tagged `[internal]` and
-  anchored by **its test name**, not by the symbol under test. The test name moves with
-  a refactor; the symbol does not.
-
-`[internal]` ACs are legitimate and expected: an invariant that no current consumer can
-observe is exactly what protects the consumer that does not exist yet. Tagging them
-keeps visible which ACs defend a product requirement and which defend a code
-invariant.
-

----
-```
-
-`base` is mandatory and is what makes drift detectable. `owner` is a human even when
-every section was drafted by an agent.
-
-## Brainstorming: the product spec
-
-The usual entry point is a human handing an agent a one-line feature idea. The output
-of that session is `<stem>.product.md`, not code and not a feature spec. Copy
-`_TEMPLATE.product.md` and fill it.
-
-Ownership: an agent may create and fill this file during `brainstorm`. From `draft`
-onwards **product owns it and agents do not edit it** — not to fix wording, not to
-resolve a marker, not to reconcile it with the code. Agents raise mismatches in the
-feature spec's `## Open questions`.
-
-If product's source of truth lives outside the repo (a tracker, a design doc), put its
-URL in the header `**Source**:` line and keep the requirement text and ids in the repo
-anyway. The ids are what the feature spec references; a link alone cannot be traced.
-
-Agent behaviour during the session:
-
-- **Ask, do not assume.** An unanswered question is recorded as
-  `[NEEDS CLARIFICATION: <the question>]`, inline where the answer would go. Filling a
-  gap with a plausible guess is the main failure mode of this state — the marker is a
-  deliverable, not a defect.
-- Ask in one round of at most five questions, ordered by how much the answer changes
-  the shape of the feature. Do not interview.
-- **No implementation in the product spec.** No file paths, symbols, libraries, event
-  types, API shapes or framework names. If a requirement cannot be stated without them,
-  it is not a product requirement.
-- Every user story must be independently deployable and demonstrable on its own. A
-  story that only makes sense once another story ships is not a story; merge it.
-- More than four priority levels means more than one feature. Split before `draft`.
-- Never invent an SC number. Ask for the target, or mark it
-  `[NEEDS CLARIFICATION]`.
-
-For protocol and infrastructure work, success criteria may be expressed as observable
-client behaviour or a wire-level invariant ("a client joining mid-session converges
-within one sync"), but still never as a code path or an internal API.
-
-`FR-###` and `SC-###` ids are immutable once assigned. Product may revise the document
-at any time, including after `in_production`, but a changed requirement gets a **new
-id** and the old one is marked superseded — never edited in place. Renumbering silently
-breaks every AC that references it, and there is no way to detect that afterwards.
-
-A new or changed FR after `implement` does not amend the current spec's scope. It is
-either a new feature spec or the next iteration; the mapping table simply shows an
-unmapped FR, which is the intended signal.
-
-## Traceability
-
-The product spec states intent; the feature spec states what must be true and how it is
-checked. They are kept in sync by ids, not by duplication.
-
-- Every `FR-###` maps to at least one acceptance criterion. Tag the AC with its
-  origin: `AC2 [FR-003] — <observable behaviour>`.
-- Every `SC-###` maps to an entry in `## Measurements` with a method. An SC with no
-  measurement blocks `exploration.signoff`.
-- Every user story maps to at least one slice. **Slice order follows story priority**
-  (P1 first) unless a technical dependency overrides it, and the override is recorded
-  in the slicing plan with its reason.
-- An AC with no `FR` origin is allowed and expected — implementation-level invariants
-  have no counterpart in the product spec. The converse is not: an unmapped FR is an
-  incomplete spec.
-- Agents do not resolve a mismatch between the two. The product spec wins on intent,
-  the feature spec wins on verification; a genuine contradiction is `blocked`.
-
-## Status state machine
-
-Transitions are explicit; an agent may perform only the ones marked (agent).

-
-- `brainstorm` → `draft`: human. Requires `<stem>.product.md` to exist with at least one
-  P1 story carrying acceptance scenarios, every FR and SC id assigned, and every
-  remaining `[NEEDS CLARIFICATION]` copied into the feature spec's `## Open questions`.
-- `draft` → `exploration.scoping`: human. Requires `## Problem` and `## Out of scope`.
-  Scoping before the branch exists is what keeps exploration from becoming the
-  long-lived branch this folder replaces.
-- `exploration.scoping` → `.iterating`: human. `experiment_ref` must name the branch.
-- `.iterating` → `.signoff`: human. Requires `## Decisions`, `## Acceptance criteria`,
-  `## Rejected alternatives` and `## Measurements` to be complete, no
-  `[NEEDS CLARIFICATION]` left in the product spec, and full traceability (below).
-- `.signoff` → `implement`: **only when all three sign-offs in `signoff:` are `ok`.**
-  This is a join, not a sequence — a single reviewer cannot advance it. On entering
-  `implement`, the exploration branch stops being a base: it is reference material,
-  and implementation branches off current `main` (see "Turning a spec into PRs").
-- `.signoff` → `.iterating`: human, on any sign-off returning changes. Reset the
-  rejecting role to `pending`; leave the others as they are.
-- `implement` → `qa`: (agent) when every acceptance criterion is covered, as recorded
-  in `## PRs`, and the feature flag is enabled in the QA environment.
-- `qa` → `in_production`: human. The flag is on by default in production.
-- `qa` → `implement`: (agent) when a QA finding needs code. See "QA feedback".
-- any active state → `blocked`: (agent) when drift or an unresolved question prevents
-  progress. Requires a drift-log entry and `blocked_from: <state>`. Do not guess and
-  continue. Leaving `blocked` returns to `blocked_from`, never to a fixed state.
-- any state → `abandoned`: human only.
-
-`in_production` is terminal. A production regression does not reopen the spec: it
-either is an ordinary bug fix with no spec, or it is a new spec. The acceptance
-criteria remain as the regression contract (see "QA feedback").
-
-## QA feedback
-
-The point of the `qa` state is not to record that testing happened. It is to make the
-spec a better regeneration source than it was before implementation. So:
-
-- Every reproduced QA finding becomes **either** a new acceptance criterion **or** a
-  new entry in `## Rejected alternatives`. Never a prose note, never only a bug
-  tracker link.
-- (agent) may **append** ACs during `qa`, with provenance:
-  `AC7 [qa: <issue ref>] — <observable behaviour>` plus its check. Appending is
-  allowed; rewriting or reordering existing ACs is not.
-- A finding that invalidates a decision does not become an AC. It sets `blocked` — a
-  decision is human-owned in every state.
-- A finding that is out of scope goes to `## Out of scope` with its issue ref, so the
-  next regeneration does not treat it as a gap.
-
-This also applies after `in_production`: a production bug that reveals a missing AC is
-appended with `[prod: <ref>]` provenance without any state change.
-
-## Required sections
-
-Order matters — agents read top-down and the first three sections are the contract.
-
-1. **`## Problem`** — up to five bullets. What breaks today, for whom, observably,
-   with the file or symbol where it breaks.
-2. **`## Decisions`** — the choices the exploration settled, each with a one-line
-   rationale. **Human-owned. An agent must never add, remove or reword a decision.**
-   If a decision is missing, set `blocked` and ask.
-3. **`## Acceptance criteria`** — the load-bearing section. Each item must be
-   mechanically checkable and name its check:
-   - `AC1 [FR-002] — <observable behaviour>` / `check: yarn vitest run src/reactions/ReactionsReader.test.tsx -t "backfill"`
-   - `AC2 [FR-002] — <observable behaviour>` / `check: manual, <exact steps>`
-   - `AC3 [internal] — <invariant>` / `check: yarn vitest run <file> -t "<test name>"`
-   An acceptance criterion without a check is a wish; reject the spec (`blocked`).
-4. **`## Rejected alternatives`** — what the experiment tried and why it failed,
-   including measurements. This exists so regeneration does not re-walk dead ends. If
-   this section is empty for a spec with an `experiment_ref`, the spec is incomplete.
-5. **`## Measurements`** — numbers from the experiment with the method used to obtain
-   them (command, hardware, load profile). Numbers without a method are not usable as
-   regression baselines and must be marked `unverified`. A baseline states its direction: a
-   count that unrelated work grows — tests passing, test files — is a floor (`≥ n`); a
-   cost — latency, CPU, bundle size — is a ceiling (`≤ n`). An exact count is stale as
-   soon as `main` moves and is not a drift finding.
-6. **`## Out of scope`** — explicit non-goals, so agents stop expanding the diff.
-7. **`## Slicing plan`** — ordered, independently mergeable PRs (see below).
-8. **`## Drift log`** — append-only, agent-written.
-9. **`## PRs`** — append-only list of `#<n> — <state> — <ACs covered>`.
-
-Optional: `## Open questions` (blocks `exploration.signoff`), `## Migration / compat` (mandatory
-whenever wire format, event schema, or a published API changes).
-
-## Turning a spec into PRs
-
-Run these steps in order. Do not skip step 2.
-
-1. **Fetch and pin.** `git fetch origin` and record `origin/main`'s sha as `head`.
-   Never start from the exploration branch, and never rebase it — the branch is
-   reference material, not a base.
-2. **Drift check** against `base..head`:
-   - Do all files, symbols and modules named in the spec still exist?
-   - Have the invariants in `## Decisions` been contradicted by changes in main?
-   - Do the commands in `## Acceptance criteria` still run?
-   Write the result as a drift-log entry. On a contradicted decision: set `blocked`,
-   do not implement.
-3. **Re-derive the slicing plan** if drift changed it. Each slice must:
-   - build and pass CI on its own,
-   - be reviewable in one sitting (target < 400 changed lines, hard stop at 800 —
-     split further rather than exceeding it),
-   - map to at least one acceptance criterion, and
-   - land behind a flag or be inert if it is not the last slice of a user-visible
-     change.
-4. **Implement one slice at a time**, branch `spec/<spec-slug>/<n>-<short>` off the
-   pinned `head`. Tests for the slice's ACs go in the same PR as the code. A PR merges
-   only when every check of every AC it lists passes on that PR: automated checks in
-   CI, manual checks performed by a human reviewer with the result recorded in the PR
-   description. An AC is *covered* once such a PR has merged.
-5. **Open the PR** linking the spec path and listing the ACs it covers. Update
-   `## PRs` and `status`.
-6. **Do not touch merged or reviewed slices.** See the regeneration rule.
-
-## The regeneration rule
-
-Regeneration from spec is only allowed **before a human has reviewed the PR**.
-
-Once review has started, the PR is a shared artifact: rebase, fix forward, push
-incremental commits. Regenerating discards the reviewer's context and silently
-invalidates their approvals. If regeneration is unavoidable after review, close the
-old PR with an explanation and open a new one — never force-push a fresh generation
-over a reviewed branch.
-
-## Cross-repo and protocol work
-
-When `repos` has more than one entry, PRs are opened in `repos` order and each PR
-body states which upstream PR it depends on. Merging out of order is a spec
-violation, not an optimisation.
-
-When `specs` is non-empty:
-- the implementation PR references the section of the MSC it implements,
-- unmerged MSCs require the implementation to be feature-flagged and documented as
-  unstable (unstable prefixes, not stable identifiers), and
-- any deviation from the MSC text is recorded in `## Drift log`, not silently
-  resolved in favour of the code.
-
-## Drift-log format
-
-Append-only, newest last:
-
-```
-### 2026-09-14 — drift check (base 4f2a1c9 → head 9b17e02)
-- `ReactionsReader.getLastReactionEvent` now takes a `CallMembership` instead of an
-  event id → AC2 and AC3 check commands still valid, slice 3 needs rework
-- BLOCKING: decision D2 assumes a membership event change may keep a hand raised; main
-  now clears all reaction relations on membership replacement. Needs owner decision.
-```
-
-Drift entries are never rewritten or deleted, including entries that were later
-resolved. The log is the record of why the implementation diverged from the
-exploration.
-
-## Hard rules
-
-- Never fill a `[NEEDS CLARIFICATION]` marker with a guess, in any state.
-- Never put file paths, symbols or library names in the product spec.
-- Never reference a file path or an internal symbol in `## Decisions` or
-  `## Acceptance criteria`. Behaviour, protocol identifiers, concepts and test names
-  only.
-- Never edit `<stem>.product.md` after `draft`, and never renumber an FR or SC id.
-- Never add a line that does not constrain the implementation, constrain its
-  verification, or record a measured fact. It goes in the sidecar or nowhere.
-- Never modify `## Decisions`, `## Problem`, or `## Acceptance criteria`. These are
-  the human contract. Propose changes in `## Open questions` and set `blocked`.
-- Never invent measurements or acceptance checks. Absent is better than plausible.
-- Never widen scope past `## Out of scope`, even when the fix looks trivial.
-- Never open a PR while `status` is `draft`, any `exploration.*`, or `blocked`.
-- Never delete a spec file. Terminal states are `in_production` or `abandoned`.
-- If the spec and current `main` disagree about how the system works, **main wins as
-  description, the spec wins as intent** — record the difference and stop.

+## Host it yourself
 
-## ✨ Key Features
+Until prebuilt tarballs are available, you'll need to build Element Call from
+source. First, clone and install the package:
 
-✅ **Decentralized & Federated** – No central authority; works across Matrix
-homeservers.  
-✅ **End-to-End Encrypted** – Secure and private calls.  
-✅ **Standalone, Widget & Component Mode** – Use as an independent app, embed
-in Matrix clients as a widget, or (experimentally) mount it as a React component
-inside your own application.  
-✅ **WebRTC-based** – No additional software required.  
-✅ **Scalable with LiveKit** – Supports large meetings via SFU
-([MSC4195: MatrixRTC using LiveKit backend](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md)).  
-✅ **Raise Hand** – Participants can signal when they want to speak, helping to
-organize the flow of the meeting.  
-✅ **Emoji Reactions** – Users can react with emojis 👍️ 🎉 👏 🤘, adding
-engagement and interactivity to the conversation.
+```
+git clone https://github.com/element-hq/element-call.git
+cd element-call
+yarn
+yarn build
+```
 
-## 🚀 Deployment & Packaging Options
+If all went well, you can now find the build output under `dist` as a series of
+static files. These can be hosted using any web server that can be configured
+with custom routes (see below).
 
-Element Call is developed using the
-[Matrix js-sdk](https://github.com/matrix-org/matrix-js-sdk) with Matroska mode.
-This allows the app to run either as a Standalone App directly connected to a
-homeserver with login interfaces or it can be used as a widget within a Matrix
-client.
+You may also wish to add a configuration file (Element Call uses the domain it's
+hosted on as a Homeserver URL by default, but you can change this in the config
+file). This goes in `public/config.json` - you can use the sample as a starting
+point:
 
-### 🖥️ Standalone Mode
+```
+cp config/config.sample.json public/config.json
+# edit public/config.json
+```
 
-<p align="center">
-  <img src="./docs/element_call_standalone.drawio.png" alt="Element Call in Standalone Mode">
-</p>
+Because Element Call uses client-side routing, your server must be able to route
+any requests to non-existing paths back to `/index.html`. For example, in Nginx
+you can achieve this with the `try_files` directive:
 
-In Standalone mode, Element Call operates as an independent, full-featured video
-conferencing web application, enabling users to join or host calls without
-requiring a separate Matrix client.
-
-### 📲 In-App Calling (Widget Mode in Messenger Apps)
-
-When used as a widget 🧩, Element Call is solely responsible for the core calling
-functionality (MatrixRTC). Authentication, event handling, and room state
-updates (via the Client-Server API) are handled by the hosting client.
-Communication between Element Call and the client is managed through the widget
-API.
-
-<p align="center">
-  <img src="./docs/element_call_widget.drawio.png" alt="Element Call in Widget Mode">
-</p>
-
-Element Call can be embedded as a widget inside apps like
-[**Element Web**](https://github.com/element-hq/element-web) or **Element X
-([iOS](https://github.com/element-hq/element-x-ios),
-[Android](https://github.com/element-hq/element-x-android))**, bringing
-**MatrixRTC** capabilities to messenger apps for seamless decentralized video
-and voice calls within Matrix rooms.
-
-> [!IMPORTANT]
-> Embedded packaging is recommended for Element Call in widget mode!
-
-### 📦 Element Call Packaging
-
-Element Call offers two packaging options: one for standalone or widget
-deployment, and another for seamless widget-based integration into messenger
-apps. A third, experimental option builds it as a React component library for
-applications that want to render a call inside their own page rather than in an
-iframe. Below is an overview of each option.
-
-**Full Package** – Supports both **Standalone** and **Widget** mode. It is
-hosted as a static web page and can be accessed via a URL when used as a widget.
-
-<p align="center">
-  <img src="./docs/full_package.drawio.png" alt="Element Call Full Package">
-</p>
-
-**Embedded Package** – Designed specifically for **Widget mode** only. It is
-bundled with a messenger app for seamless integration and this is the
-recommended method for embedding Element Call.
-
-<p align="center">
-  <img src="./docs/embedded_package.drawio.png" alt="Element Call Embedded Package">
-</p>
-
-**Component Package (experimental)** – A library build of Element Call as a
-React component, consumed as a dependency by a host application that already
-has a Matrix client. See
-[Element Call as a component](#element-call-as-a-component-experimental) below.
-
-For more details on the packages, see the
-[Embedded vs. Standalone Guide](./docs/embedded_standalone.md).
-
-## 🛠️ Self-Hosting
-
-For operating and deploying Element Call on your own server, refer to the
-[**Self-Hosting Guide**](./docs/self_hosting.md).
-
-## MatrixRTC Transports
-
-For proper operation of Element Call, each deployment needs to set up a
-MatrixRTC transport in the form of a LiveKit server as outlined in the
-[Self-Hosting Guide](./docs/self_hosting.md). A typical federated site
-deployment for three different sites A, B and C is depicted below.
-
-<p align="center">
-  <img src="./docs/Federated_Setup.drawio.png" alt="Element Call federated setup">
-</p>
-
-### Transport Discovery
-
-Element Call discovers the available MatrixRTC transports (as defined by
-[MSC4519](https://github.com/matrix-org/matrix-spec-proposals/pull/4519)) by
-hitting the `GET /_matrix/client/unstable/org.matrix.msc4143/rtc/transports`
-endpoint of the Client-Server API. An example response:
-
-```json
-{
-  "rtc_transports": [
-    {
-      "type": "livekit",
-      "livekit_service_url": "https://matrix-rtc.example.com/livekit/jwt"
+```
+server {
+    ...
+    location / {
+        ...
+        try_files $uri /$uri /index.html;
     }
-  ]
 }
 ```
 
-where the format for MatrixRTC using LiveKit backend is defined in
-[MSC4195](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md).
-In the example above Matrix clients do discover a focus of type `livekit` which
-points them to a [MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)
-via `livekit_service_url`.
+By default, the app expects you to have a Matrix homeserver (such as
+[Synapse](https://element-hq.github.io/synapse/latest/setup/installation.html))
+installed locally and running on port 8008. If you wish to use a homeserver on a
+different URL or one that is hosted on a different server, you can add a config
+file as above, and include the homeserver URL that you'd like to use.
 
-### Backend Selection
+Element Call requires a homeserver with registration enabled without any 3pid or
+token requirements, if you want it to be used by unregistered users.
+Furthermore, it is not recommended to use it with an existing homeserver where
+user accounts have joined normal rooms, as it may not be able to handle those
+yet and it may behave unreliably.
 
-- Each call participant proposes their discovered MatrixRTC transport from
-  `org.matrix.msc4143.rtc_foci` in their `org.matrix.msc3401.call.member` state event.
-- For the **LiveKit** MatrixRTC backend
-  ([MSC4195](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md)),
-  the **first participant who joined the call** defines which backend will be used for this call via
-  the `foci_preferred` key in their `org.matrix.msc3401.call.member` state event.
-- During the actual call join flow, the **[MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)**
-  provides the client with the **LiveKit SFU WebSocket URL** and an
-  **access JWT token** in order to exchange media via WebRTC.
+Therefore, to use a self-hosted homeserver, this is recommended to be a new
+server where any user account created has not joined any normal rooms anywhere
+in the Matrix federated network. The homeserver used can be setup to disable
+federation, so as to prevent spam registrations (if you keep registrations open)
+and to ensure Element Call continues to work in case any user decides to log in
+to their Element Call account using the standard Element app and joins normal
+rooms that Element Call cannot handle.
 
-The example below illustrates how backend selection works across **Matrix
-federation**, using the setup from sites A, B, and C. It demonstrates backend
-selection for **Matrix rooms 123 and 456**, which include users from different
-homeservers.
+## Configuration
 
-<p align="center">
-  <img src="./docs/SFU_selection.drawio.png" alt="Element Call SFU selection over Matrix federation">

+There are currently two different config files. `.env` holds variables that are
+used at build time, while `public/config.json` holds variables that are used at
+runtime. Documentation and default values for `public/config.json` can be found
+in [ConfigOptions.ts](src/config/ConfigOptions.ts).
 
-## 🌍 Translation
+If you're using [Synapse](https://github.com/element-hq/synapse/), you'll need
+to additionally add the following to `homeserver.yaml` or Element Call won't
+work:
+
+```
+experimental_features:
+    # MSC3266: Room summary API. Used for knocking over federation
+    msc3266_enabled: true
+
+# The maximum allowed duration by which sent events can be delayed, as
+# per MSC4140.
+max_event_delay_duration: 24h
+
+rc_message:
+  # This needs to match at least the heart-beat frequency plus a bit of headroom
+  # Currently the heart-beat is every 5 seconds which translates into a rate of 0.2s
+  per_second: 0.5
+  burst_count: 30
+```
+
+MSC3266 allows to request a room summary of rooms you are not joined. The
+summary contains the room join rules. We need that to decide if the user gets
+prompted with the option to knock ("Request to join call"), a cannot join error or the
+join view.
+
+Element Call requires a Livekit SFU alongside a [Livekit JWT
+service](https://github.com/element-hq/lk-jwt-service) to work. The url to the
+Livekit JWT service can either be configured in the config of Element Call
+(fallback/legacy configuration) or be configured by your homeserver via the
+`.well-known/matrix/client`. This is the recommended method.
+
+The configuration is a list of Foci configs:
+
+```json
+"org.matrix.msc4143.rtc_foci": [
+    {
+        "type": "livekit",
+        "livekit_service_url": "https://someurl.com"
+    },
+     {
+        "type": "livekit",
+        "livekit_service_url": "https://livekit2.com"
+    },
+    {
+        "type": "another_foci",
+        "props_for_another_foci": "val"
+    },
+]
+```

-## 🛠️ Development
-
-### Dependencies
-
-- Node.js (e.g. via [nvm](https://github.com/nvm-sh/nvm))
-- [Corepack](https://github.com/nodejs/corepack) (not bundled with Node.js anymore starting from 25.0.0)
-- Docker client and runtime + Docker Compose (for the backend)
-  - On macOS you can install everything with `brew install colima docker docker-compose`
+## Development
 
 ### Frontend
 
-To get started clone and set up this project:
+Element Call is built against
+[matrix-js-sdk](https://github.com/matrix-org/matrix-js-sdk/pull/2553). To get
+started, clone, install, and link the package:
 
-```sh
-git clone https://github.com/element-hq/element-call.git
-cd element-call
-corepack enable
-pnpm install
+```
+git clone https://github.com/matrix-org/matrix-js-sdk.git
+cd matrix-js-sdk
+yarn
+yarn link
 ```
 
-To use it, create a local config by, e.g.,
-`cp ./config/config.devenv.json ./public/config.json` and adapt it if necessary.
-The `config.devenv.json` config should work with the backend development
-environment as outlined in the next section out of box.
+Next, we can set up this project:
+
+```
+git clone https://github.com/element-hq/element-call.git
+cd element-call
+yarn
+yarn link matrix-js-sdk
+```
+
+To use it, create a local config by, e.g., `cp ./config/config.devenv.json
+./public/config.json` and adapt it if necessary. The `config.devenv.json` config
+should work with the backend development environment as outlined in the next
+section out of box.
+
+(Be aware, that this `config.devenv.json` is exposing a deprecated fallback
+LiveKit config key. If the homeserver advertises SFU backend via
+`.well-known/matrix/client` this has precedence.)
 
 You're now ready to launch the development server:
 
-```sh
-pnpm dev
 ```
-
-See also:
-
-- [Developing with linked packages](./docs/linking.md)
-
-#### 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
+yarn dev
 ```
 
-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
-and is memory-hungry, 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` and `livekit-client` itself, since the bundle leaves
-them external.

 These use a test 'secret' published in this repository, so this must be used
 only for local development and **_never be exposed to the public Internet._**
 
-Make sure your Docker runtime is running (e.g. via `colima start`) and then start
-the backend components:
-
-```sh
-pnpm backend
-# or for podman-compose:
-# podman-compose -f docker-compose-dev.yml up
-```
-
-> [!NOTE]
-> To ensure your local development frontend functions properly, you’ll need to
-> add certificate exceptions in your browser for `https://localhost:3000` and
-> `https://matrix-rtc.m.localhost/livekit/jwt/healthz`. This can be done either
-> by adding the minimum localhost CA
-> ([./backend/dev_tls_local-ca.crt](./backend/dev_tls_local-ca.crt)) to your web
-> browser's trusted certificates or by simply copying and pasting each URL into
-> your browser’s address bar and follow the prompts to add the exception.

-### Updating snapshots
-
-To update snapshots used in tests, use Vitest's `-u` flag, e.g.:
-
-```sh
-pnpm test DeveloperSettingsTab -u
-```
-
-### Playwright tests
-
-Our Playwright tests run automatically as part of our CI along with our other
-tests, on every pull request.
-
-You may need to follow instructions to set up your development environment for
-running Playwright by following
-<https://playwright.dev/docs/browsers#install-browsers> and
-<https://playwright.dev/docs/browsers#install-system-dependencies>.
-
-However the Playwright tests are run, an element-call instance must be running
-on https://localhost:3000 (this is configured in `playwright.config.ts`) - this
-is what will be tested. The tests under `playwright/component` instead drive
-the component harness (`pnpm dev:component`) on https://localhost:3001, which
-Playwright starts as a second web server; it is always a Vite dev server, even
-when the app itself is served from Docker with `USE_DOCKER`.
-
-The local backend environment should be running for the test to work:
-`pnpm backend`
-
-There are a few different ways to run the tests yourself. The simplest is to
-run:
-
-```shell
-pnpm run test:playwright
-```
-
-This will run the Playwright tests once, non-interactively.
-
-There is a more user-friendly way to run the tests in interactive mode:
-
-```shell
-pnpm run test:playwright:open
-```
-
-The easiest way to develop new test is to use the codegen feature of Playwright:
-
-```shell
-npx playwright codegen
-```
-
-This will record your action and write the test code for you. Use the tool bar
-to test visibility, text content and clicking.
-
-##### Investigate a failed test from the CI
-
-In the failed action page, click on the failed job, then scroll down to the
-`upload-artifact` step. You will find a link to download the zip report, as per:
+Run backend components:

-Unzip the report then use this command to open the report in your browser:
-
-```shell
-npx playwright show-report ~/Downloads/playwright-report/

-# Testing Element-Call in widget mode
-
-When running `pnpm backend` the latest element-web develop will be deployed and served on `http://localhost:8081`.
-In a development environment, you might prefer to just use the `element-web` repo directly, but this setup is useful for CI/CD testing.
-
-## Setup
-
-The element-web configuration is modified to:
-
-- Enable to use the local widget instance (`element_call.url` https://localhost:3000).
-- Enable the labs features (`feature_group_calls`, `feature_element_call_video_rooms`).
-
-The default configuration used by docker-compose is in `test-container/config.json`. There is a fixture for playwright
-that uses
-
-## Running the element-web instance
-
-It is part of the existing backend setup. To start the backend, run:
-
-```sh
-pnpm backend
-```
-
-Then open `http://localhost:8081` in your browser.
-
-## Basic fixture
-
-A base fixture is provided in `/playwright/fixtures/widget-user.ts` that will register two users that shares a room.

-// this bundle, to the root element below (see build/scopeStylesToRoot.ts), so
-// that the host's document is left as it was.
-//
-// 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

-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)
-
-```
-  ➜  Local:   https://m.localhost:3000/                                                                                                                                                                 12:06:48
-  ➜  Local:   https://vite.m.localhost:3000/                                                                                                                                                            12:06:48
-  ➜  Local:   https://vite.othersite.m.localhost:3000/                                                                                                                                                  12:06:48
-  ➜  Local:   https://vite.nip.io:3000/                                                                                                                                                                 12:06:48
-  ➜  Network: https://192.168.0.122:3000/

-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.

 # Global JS controls
 
-A few aspects of Element Call's interface can be controlled through a global API on the `window`.
-
-## Picture-in-picture
+A few aspects of Element Call's interface can be controlled through a global API on the `window`:
 
 - `controls.canEnterPip(): boolean` Determines whether it's possible to enter picture-in-picture mode.
 - `controls.enablePip(): void` Puts the call interface into picture-in-picture mode. Throws if not in a call.
 - `controls.disablePip(): void` Takes the call interface out of picture-in-picture mode, restoring it to its natural display mode. Throws if not in a call.
-- `controls.onPipMediaOrientationUpdate: ((orientation: "landscape"|"portrait") => void) | undefined` Callback called whenever the PiP media orientation changes.
-  The client should track this value to already initiate the pip in the right orientation.
-  It should update the orientation of the current Pip window when called.
-
-## 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.
-
-- `controls.setAvailableAudioDevices(devices: { id: string, name: string, forEarpiece?: boolean, isEarpiece?: boolean isSpeaker?: boolean, isExternalHeadset?: boolean }[]): void` Sets the list of available audio outputs. `forEarpiece` is used on iOS only.
-  It flags the device that should be used if the user selects earpiece mode. This should be the main stereo loudspeaker of the device.
-- `controls.onAudioDeviceSelect: ((id: string) => void) | undefined` Callback called whenever the user or application selects a new audio output.
-- `controls.setAudioDevice(id: string): void` Sets the selected audio device in Element Call's menu. This should be used if the OS decides to automatically switch to Bluetooth, for example.
-- `controls.setAudioEnabled(enabled: boolean)` Enables/disables all audio output from the application. Output is enabled by default.
-- `controls.onAudioPlaybackStarted: ((id: string) => void) | undefined`: This will be called the first time we start
-  playing audio in the webview. It can be helpful to do device setup on the native app when the webviews audio is ready.
-  In particular android is using it to setup the output channel so that the call volume can
-  be controlled by the hardware volume rocker.
-
-## Element Call button delegation
-
-Callbacks for buttons in EC that are handled by the native application
-
-- `showNativeAudioDevicePicker: (() => void) | undefined`. Callback called whenever the user presses the output button in the settings menu.
-  This button is only shown on iOS. (`/iPad|iPhone|iPod|Mac/.test(navigator.userAgent)`)
-- `onBackButtonPressed: (() => void) | undefined`. Callback when the webview detects a tab on the header's back button.

+## Embedded vs standalone mode
+
+Element call is developed using the js-sdk with matroska mode. This means the app can run either as a standalone app directly connected to a homeserver providing login interfaces or it can be used as a widget.
+
+As a widget the app only uses the core calling (matrixRTC) parts. The rest (authentication, sending events, getting room state updates about calls) is done by the hosting client.
+Element Call and the hosting client are connected via the widget api.
+
+Element call detects that it is run as a widget if a widgetId is defined in the url parameters. If `widgetId` is present element call will try to connect to the client via the widget postMessage api using the parameters provided in [Url Format and parameters
+](./url-params.md).
