The OpenID flow moves to src/livekit/auth/openID.ts with the SFU config
types in a sibling file, takes an options object, and replaces the
MatrixRTC mode with the role we take on the transport plus the session's
slot ID instead of a hard-coded m.call#ROOM.
This changes behaviour: publishers on a livekit_service_url transport
always use the legacy /sfu/get endpoint, so that subscribers can predict
their user:device participant identity, and subscribers always use the
default /get_token endpoint. The MatrixRTC mode no longer influences which
endpoint is used.
On the SDK this lands as sdk/src/media-backend/livekit/auth/ with the connection map, the discriminated connection state and the client-server API flow of the following commits of element-hq/element-call#4331, which rewrite the same files:
- Model ConnectionState as a discriminated union
- Show the whole transport in debug UI and logs (SDK part)
- Let the publishing Connection authenticate itself
- Reduce ConnectionManager to a ConnectionMap
- Use the unstable LiveKit transport type
- Identify transports by server name as well as URLs
- Get SFU tokens and delegate delayed leaves through the MSC4195 CS API
- Fall back to get_token as subscriber on widget API errors
- Share a connection between homeservers using the same JWT service
- Make the auth choice mode independent again

(cherry picked from commit adb380cd9ed108856e42d992fc03ced8c44f1e56)
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.
