j.Join() blocks on WaitJingle until Jicofo sends session-initiate,
which only happens when a second participant joins the room. With the
transport-level connect timeout (30-60s), the server crashes if no one
joins in time.
Switch to j.JoinMUC() which returns immediately after joining the MUC.
A background goroutine (waitForJingle) waits for session-initiate and
then opens the bridge + negotiates the PeerConnection. This way Connect
succeeds as soon as the XMPP connection is established, regardless of
whether another participant is present.
When the JVB bridge disconnects but the session is not yet closed
(e.g. during a pending reconnect), rtcpKeepalive spins indefinitely
logging "rtcp keepalive write: io: read/write on closed pipe" every
5 seconds. The process appears alive but is functionally dead —
systemd Restart=always never triggers and the instance becomes
permanently wedged.
Add an error counter that triggers requestReconnect after 3
consecutive WriteRTCP failures, allowing the supervisor to
tear down and re-establish the bridge connection. Reset the
counter on any successful write.

internal/carrier and internal/carrier/builtin sat between transports and
engines, wrapping every engine.Session in carrier.Session +
engineByteStream/engineVideoTrack adapters that mechanically proxied every
method. That layer existed solely to translate Capabilities/AddTrack names;
no behaviour lived above engine.
Replace with internal/engine/builtin: a name-keyed registry that calls
auth.Issue and engine.New directly. Transports look up engine.Session via
enginebuiltin.Open, then type-assert engine.VideoTrackCapable for video
transports. A small per-transport engineVideoSession adapter unifies the
reconnect callback signature (engine uses func(*webrtc.DataChannel); the
transports want func()).
Updates:
- internal/engine/builtin/builtin.go: new Register/Open registry + auth
pass-through ("none") + auth-driven factories for jazz/telemost/wbstream/jitsi.
- internal/transport/datachannel/transport.go: uses engine.Session directly
via Capabilities().ByteStream check.
- internal/transport/{seichannel,videochannel,vp8channel}: each gains an
engineVideoSession adapter and routes Connect/Send/Close/AddTrack through
the engine session.
- internal/app/session: imports enginebuiltin; carrier.Available() →
enginebuiltin.Available().
- pkg/olcrtc/olcrtc.go: switches to enginebuiltin.RegisterDefaults.
- internal/carrier and internal/carrier/builtin: deleted.
- Tests rewritten to register a fakeEngineSession (implements engine.Session
+ engine.VideoTrackCapable) through enginebuiltin.Register. The e2e
memoryStream gains the same dual interface so memorySession is gone.
