Phase 3d-2 of the Clubhouse/nests integration. Ties HTTP auth (3a) +
WebTransport (3b-1 stub) + MoQ session (3c) under a single
`connectNestsListener()` entry point with an observable state
machine, so audio-room callers see one resource and one StateFlow
instead of three layered handshakes. Pure commonMain — fully tested
against fakes; no network or Android needed.
commonMain (nestsclient):
- `NestsListener` interface — `state: StateFlow<NestsListenerState>`,
`subscribeSpeaker(pubkeyHex)`, `close()`. nests namespaces each
speaker's track as `["nests", <roomId>]` with the speaker's pubkey
hex as track name; subscribeSpeaker fills that in.
- `NestsListenerState` sealed class:
* Idle
* Connecting(step = ResolvingRoom | OpeningTransport | MoqHandshake)
* Connected(roomInfo, negotiatedMoqVersion)
* Failed(reason, cause?)
* Closed
- `DefaultNestsListener` — straight delegation to MoqSession once
connected.
- `connectNestsListener(httpClient, transport, scope, serviceBase,
roomId, signer, supportedMoqVersions)` — walks the three handshake
steps. Each failure short-circuits to Failed with a clear reason
string and the underlying cause attached; transport is torn down on
partial-handshake failure.
- `parseEndpoint(url)` — hand-rolled URL splitter so commonMain stays
free of a URL-library dependency. Handles default-port stripping,
rejects userinfo, preserves query strings.
commonTest:
- `NestsConnectTest` (5 cases, all using fakes):
* Happy path: walks resolveRoom -> transport.connect -> MoQ SETUP,
asserts state lands on Connected with the right roomInfo +
negotiated version, and verifies the transport saw the parsed
authority/path/bearer.
* resolveRoom failure short-circuits without touching transport.
* Transport handshake failure short-circuits with the right kind in
the reason.
* Malformed endpoint URL short-circuits.
* parseEndpoint covers default-port stripping, explicit port,
pathless URL, query string preservation.
This completes the pure-Kotlin integration. The only seam left
between `connectNestsListener()` and audible audio is the Kwik-backed
WebTransportFactory implementation (Phase 3b-2). When that lands, an
Amethyst AudioRoomViewModel can wire the existing AudioRoomStage to:
state = MutableStateFlow(NestsListenerState.Idle)
listener = connectNestsListener(...)
for each speaker p: AudioRoomPlayer(MediaCodecOpusDecoder(),
AudioTrackPlayer(), scope).play(listener.subscribeSpeaker(p).objects)
…and audio plays.
