The developer setting that overrode the LiveKit service URL becomes a
JSON transport, so that a `url`-only or combined transport can be tested
against a homeserver that does not advertise one yet. The settings modal
shows each LiveKit room's role instead of a never-populated isLocal flag.
On the SDK the participation options take a whole Transport for the override and the fallback instead of two LiveKit service URLs, which also takes the last LiveKit knowledge out of transport discovery.

A member authenticated through the legacy JWT endpoint publishes under a
`user:device` identity, while one authenticated through the default
endpoint publishes under a hashed identity. Both are listed in the
membership's backend identities, so match against the whole list rather
than only the primary one.
On the SDK this is RTCMember.backendIdentities, which the LiveKit backend matches media and data packets against; the harness keys its tiles by the membership id, which the backend identity no longer tells apart.

The SDK now takes `publish` requests and audio output control directly
in the main options object, removing the separate `LocalMediaInputs`
type. Audio output device selection moves from a reactive behavior to an
imperative method on `MatrixRTCClient`, giving hosts direct control over
when devices switch.
The session speaks MatrixRTC and sees media through MediaBackend in
sdk/src/backend/api.ts. Everything LiveKit lives in
sdk/src/backend/livekit/,
the only place in the SDK that imports livekit-client; the import
boundary rule
now enforces that outside sdk/src/backend/ the LiveKit packages appear
in type
imports only.
The seam sits above the connection manager: one connection per transport
url
is the LiveKit multi-SFU strategy, not a MatrixRTC concept, so a
cascading SFU
or full mesh replaces the folder, not the session. A backend prepares
the local
transport the session discovered (the token exchange and the delegation
probe,
reported as canDelegateDelayedLeave), hands the delayed leave over per
delay
id, gives the local member one publish switch plus publish/unpublish,
builds a
remote member's media from its membership and registers that
membership's
transport for as long as the member lives, and reports its connections
for the
transport registry, which keys on the raw transport serialised with
sorted
keys. The backend's context carries no Matrix client (a backend picks
what it
calls in its own options), no membership list, and no js-sdk session:
media
keys arrive as a stream replayed on subscribe, and MatrixKeyProvider
subscribes
to it. The MatrixRTC mode no longer reaches LiveKit; it becomes a
tokenEndpoint
choice made where the default backend is built.
Two behaviour changes ride along. Publishing is one boolean, joined and
homeserver reachable, where before a sync hiccup after leave() resumed
the
upstream of tracks that were meant to stay silent. And
ResolvedConnection keeps
one ResolvedTransport object per fetch, so a state change no longer
reads as a
change of what was fetched.
MatrixRTCClientOptions gains backend?: MediaBackendFactory, defaulting
to
createLivekitBackend built from the client options.
authenticateWithTransport
takes tokenEndpoint instead of matrixRTCMode.
membership$ is typed as RTCMembership, the subset of the js-sdk CallMembership that hosts read. UnknownCallError is UnknownRTCError throughout, not only in the export. applicationData reaches the membership whole, since the js-sdk takes it next to the intent. The plan records the three slices as implemented.

One way to put media on the session: publish(request) resolves with the local track once LiveKit has it, and unpublish(id) removes it. A request names a source with its device, processor and capture settings, so CaptureSettings on the client options goes, as do setMicrophoneEnabled and setCameraEnabled on the client and the four screen share fields on the local member; sharing is tracks$ having a screenShare track, and a capture failure rejects the promise. LocalMediaInputs becomes the list of initial requests, which also become the room defaults so that one permission prompt covers microphone and camera. The publisher keeps the requests across a reconnection and republishes what is not muted. The harness gains a Share screen button.

Our own tracks are LocalAudioMediaTrack and LocalVideoMediaTrack, with setEnabled and setDevice, and on video facingMode$, switchFacingMode and setProcessor. switchCamera on the local media goes, as do the device and processor behaviors in LocalMediaInputs: a host calls the track when its setting changes instead of the SDK watching behaviors it does not own. The input device ids and the processor stay as initial values for the tracks created at the join. setMicrophoneEnabled and setCameraEnabled stay for the case of no track yet.

Update the public API to export the primitives and operators the call
model needs, and change `LocalMediaInputs` from observable flags to
immediate booleans with imperative setters. Add session timings, media
quality and capture settings as configuration options, and allow the
host to override the transport discovery with explicit URLs.
