Merge upstream element-hq/element-call tag v0.25.0 into the Lotus fork
(previous base: v0.20.1; actual merge-base v0.20.1-rc.1). Every Lotus
feature and all six io.lotus.* widget actions are preserved. Version
bumped to 0.25.0-lotus.1.
Conflict files and how each Lotus hunk was re-expressed:
* src/state/CallViewModel/remoteMembers/ConnectionFactory.ts
Upstream moved echoCancellation/noiseSuppression/autoGainControl from
constructor params (fed by URL params) to persisted Settings
(settings.ts) with a developer-settings UI. The cinny host still drives
these per call via URL params (noiseSuppression=false /
autoGainControl=false when the in-source ML denoiser is active, so the
model gets a raw mic) - taking upstream verbatim would silently break
the ML denoise tier. Re-wired as AND semantics in generateRoomOption():
a constraint is enabled only if BOTH the Setting and the URL param
allow it. Params default to true, so with no params this is
byte-for-byte upstream behaviour. Upstream's own echoCancellation /
noiseSuppression URL params (still parsed but dead in v0.25.0) work
again as a side effect. Lotus autoGainControl URL param kept in
UrlParams.ts (auto-merged, unchanged).
* src/state/CallViewModel/remoteMembers/ECConnectionFactory.test.ts
Took upstream (tests now drive via Settings). The lost Lotus coverage
is restored in a NEW colocated file src/lotus/lotusAudioConstraints.test.ts
(3 tests) so the upstream test file stays pristine. Verified the new
test fails against pure-upstream ConnectionFactory and passes with the
re-wiring.
* src/state/CallViewModel/CallViewModel.ts
Three small hunks: kept both the Lotus `userMedia$` interface member
and upstream's new `keyRotationSuppressed$`; dropped the three Lotus
audio constructor args (mechanism removed upstream, see above); kept
both in the returned object. The [lotus #4] overrideSpotlight$ routing,
manualSpotlightUserId$ and setManualSpotlight auto-merged; verified
against upstream's changed ringingMedia$ (now single-or-null instead
of array) - the merge correctly took upstream's outer branch and the
inner screenShares$/spotlightSpeaker$ logic that lotusSpotlight.ts
mirrors is unchanged upstream.
* src/index.css
Kept both: Lotus lotus-transparent / lotus-theme blocks and upstream's
new body[data-background="gradient"]::before full-viewport gradient.
The naive merge swallowed the closing brace of body.lotus-theme -
restored. Added a rule hiding the new gradient pseudo-element under
body.lotus-transparent, since it would otherwise paint over the
transparent body and hide the host wallpaper.
* src/components/CallFooterViewModel.tsx, src/components/CallFooter.stories.tsx
No Lotus content - pure upstream-vs-upstream conflicts caused by the
merge base being v0.20.1-rc.1. Took upstream (layoutMode ->
layoutSwitchVm; setLayoutMode removed). No Lotus code uses
setGridMode/layoutMode.
Non-conflicting but reviewed:
* src/widget.ts auto-merged cleanly. Upstream's removal of .well-known
transport advertisement and the new RTC-transport capability request
did not touch the action registration loop the LOTUS_TO_WIDGET_ACTIONS
spread and widget.lazyActions ride on - nothing to re-wire.
* src/room/InCallView.tsx, src/useAudioContext.tsx, src/useTheme.ts,
src/tile/MediaView.tsx(+.module.css), src/UrlParams.ts(+test),
all *.module.css and .gitea/workflows/ci.yml auto-merged; each diff
against v0.25.0 was checked to equal the original Lotus hunk.
* src/button/Button.module.css: the merge appended an exact duplicate
of upstream's `.rotate`/`@keyframes spin` block (rc.1 merge-base
artefact) - reset to upstream verbatim.
* src/grid/OneOnOnePortraitLayout.module.css was renamed upstream to
OneOnOneMobileLayout.module.css; git followed the rename and the Lotus
safe-area PiP inset fix applies there (the --content-inset-* vars it
uses still exist upstream).
Tooling changes inherited from upstream that affect the fork:
* eslint + prettier were replaced by oxlint + oxfmt (`pnpm lint:oxlint`,
`pnpm format:check`). oxlint flagged 10 issues, all in src/lotus/*:
8x no-meaningless-void-operator (dropped the `void` before void-typed
widget transport.reply / callbacks - no behaviour change), 1x
consistent-type-imports (lotusWidget.ts: `import type`), and 2x
unicorn/no-useless-spread in lotusAudioInject.ts which are FALSE
POSITIVES - `[...activeClips]` is a required defensive copy because
abort() deletes from the Set during iteration; suppressed with an
explanatory eslint-disable-next-line. oxfmt reformatted 7 Lotus
touched files (whitespace only).
* packageManager bumped by upstream to pnpm@11.21.0, which requires
Node >= 22.13 (uses node:sqlite). Node 20 cannot run it; pnpm 10.33
cannot read the new lockfile either (matrix-js-sdk is now a git
dependency on develop, using a version-union pnpm 10 rejects). Fork CI
already uses Node 24 (.node-version), so CI is unaffected.
* matrix-js-sdk is now github:matrix-org/matrix-js-sdk#develop (pinned
by commit in pnpm-lock.yaml).
Lotus behaviour NOT preserved: none found.
Verification (Node 24.11.1, pnpm 11.21.0): pnpm install --frozen-lockfile
OK (lockfile taken from upstream unchanged, no regeneration needed);
tsc clean; oxlint clean; oxfmt --check clean; knip exit 0 (2 config
hints in upstream knip.ts only); vitest unit 84 files / 627 passed /
9 skipped; build:embedded OK, staged to embedded/web/dist (44M), all
six io.lotus.* action strings present in the bundle.

- EC1: lotusQuality — track + clearTimeout the 500ms settle re-apply per room
(was leaking a timer that fired on torn-down rooms).
- EC2/EC3: lotusQuality + lotusAudioInject drive off vm.allConnections$ instead
of the remote-gated livekitRoomItems$ (were no-ops when alone), matching
lotusDenoise.
- EC4: lotusDecorations resets its roster to {} on teardown so a decoration from
a previous call can't render on a shared user in the next one.
- EC5: hoisted a stable useSyncExternalStore subscribe fn (was re-subscribing
every tile render).
- EC6: lotusFocus only sets the spotlight when the userId field is present
(a partial payload no longer clears the pin).
tsc clean. Needs a republish to ship.

playInjectedClip only registered its cleanup (and thus became abortable by a
later clip's replace-mode loop) AFTER publishing. Two inject actions fired in
quick succession could both pass their fetch/decode/publish awaits before
either was registered, so both tracks got published.
Register a synchronous placeholder abort BEFORE the first await: it aborts the
in-flight fetch and flips an `aborted` flag checked after every await, so a
newer clip cancels the older one during the vulnerable window. The real
cleanup replaces the placeholder once the track is live, and if we were
superseded mid-publish we tear the just-published track down immediately.

playInjectedClip now stops any in-flight clip (via the existing idempotent
cleanup) before starting a new one, so rapid taps replace rather than
overlap/stack — no track leak. The host also debounces the button.

Holistic security audit findings:
- C1 (CRITICAL): force lotusDenoiseBase to same-origin before it reaches
audioWorklet.addModule()/fetch — a crafted call-link param could
otherwise load attacker JS/WASM as a worklet processing the live mic.
Non-same-origin/malformed values fall back to bundled ./denoise/.
- H1 (HIGH): gate audio-inject behind explicit lotusAudioInject=1 (still
acks the action so no transport hang) — it publishes under the local
user's identity, so it must not be silently armed for every call.
- M1 (MED): cap the decoration roster at 512 entries.

- resume() the AudioContext (host postMessage isn't a gesture) so the clip
isn't silent; warn if it stays suspended (HIGH).
- Close the AudioContext on decode failure (no context leak) (MED).
- Abort in-flight clips on teardown (unmount/vm-change/leave) so audio
doesn't keep blasting to peers (MED).
- Stop the cloned MediaStreamTrack when a room publish fails (MED).
- Validate url is https/blob and fetch with credentials:omit, mode:cors
(MED security).
- Guard against NaN clip duration; fix stale enum doc comment.

Adds io.lotus.inject_audio (toWidget): mixes a soundboard clip into the
call so other participants hear it. Publishes the clip as a separate
Unknown-source LiveKit track (rendered by MatrixAudioRenderer) rather than
splicing into the mic track, so the denoise pipeline is untouched; the
track is unpublished when the clip ends (with a 30s safety cap). This is
the real call-audio injection that was impossible against the prebuilt EC
bundle. Additive: no-op unless the host sends the action.
