fix(nestsClient): fix race + leaks + Android encoder/decoder bugs from second audit
A fresh audit caught a real race in the round-1 subscribe() rewrite plus several distinct bugs in the Android MediaCodec layer. **MoqLiteSession.subscribe() race regression** — the launched collector that reads the SubscribeResponse and watches for peer FIN ran cleanup (remove from subscriptionsBySubscribeId, close frames) before subscribe() itself reached the post-await registration. If the publisher FIN'd immediately after sending Ok, the collector exited first against an empty map; subscribe() then registered the subscription, leaving frames in the map with no live collector to ever close it on transport drop. Consumer hung forever — exactly the failure mode round-1 fix #3 was supposed to prevent. Fix: pre-register the subscription BEFORE launching the collector. Drop unused `ok` field from ListenerSubscription. **MoqLiteNestsSpeaker.startBroadcasting publisher leak** — if session.publish() succeeded but broadcaster.start() then threw (mic permission denied, AudioRecord allocation failure), the publisher was never closed and stayed registered as session.activePublisher, permanently blocking subsequent startBroadcasting calls. **runCatching{suspend close} swallowing CancellationException** — MoqLiteNestsSpeaker.close, MoqLiteBroadcastHandle.close, MoqLiteNestsListener.close all wrapped suspending closes in runCatching, breaking structured cancellation when the parent scope cancelled teardown. Replaced with explicit cancel-rethrowing try/catch. **MediaCodecOpusDecoder ArrayList<Short> boxing on every audio frame** — at 50 fps × 960 samples × N speakers ≈ 48 000 boxed Short allocations/sec/speaker on the audio hot path. Rewritten to write directly into a pre-sized ShortArray via ShortBuffer.get(dst, off, len). **MediaCodecOpusEncoder bugs** - KEY_AAC_PROFILE = AACObjectLC was being set on an audio/opus encoder. Meaningless for Opus; stricter Codec2 stacks on Android 13+ reject the configure() call with IllegalArgumentException and surface as DeviceUnavailable. Removed. - The drain loop's INFO_OUTPUT_FORMAT_CHANGED branch had no progress guard. A buggy encoder re-emitting FORMAT_CHANGED without producing output would busy-spin against the 10 ms dequeue timeout. Now absorbed at most once per encode call. Same guard added to the decoder. Adds regression test: - frames_flow_completes_when_peer_FINs_immediately_after_Ok 224 tests pass, 0 failures. Android target compiles clean. |

fix(nestsClient): perf + robustness — jitter, frame buffer, defensive bounds, send-error guard
- NestsReconnectPolicy gains a `jitter` parameter (default 0.3, AWS-
style equal jitter). Without it, every client reconnecting after
a relay restart retries on the identical 1s/2s/4s/… schedule and
thunders the relay during recovery. delayForAttempt also accepts
an explicit Random source for deterministic tests.
- MoqLiteFrameBuffer decouples capacity from size so power-of-two
growth actually amortises (the old shape allocated a fresh
ByteArray then truncated capacity back to `needed` per chunk,
defeating doubling). Adds a guard against varint reads past the
live region into uninitialised slack capacity.
- prefixWithType inlines the size-prefix wrap so a publisher
SubscribeOk/Drop reply doesn't allocate three ByteArrays.
- MoqLiteSubscribeOk gains the same `init { require(priority in 0..255) }`
bounds check its sibling MoqLiteSubscribe has — a buggy caller
building a malformed Ok reply now fails loudly instead of writing
a truncated byte on the wire.
- NestBroadcaster + NestMoqLiteBroadcaster track consecutive
publisher.send exception count and bail after 250 (~5 s at 50 fps)
instead of holding the mic open forever on a permanently dead
transport. publisher.send returning `false` (no inbound
subscriber) is NOT counted — empty rooms are a normal state.
Adds 8 regression tests:
- 5 in MoqLiteFrameBufferTest (multi-chunk reads, back-to-back
payloads, growth amortisation, compact, varint past-live guard)
- 3 in NestsReconnectPolicyTest (jitter spread band, jitter=0
determinism, jitter=1 collapses to 0..base)
223 tests pass, 0 failures.

fix(nestsClient): more bugs from review — IETF parser, leaks, IPv6, URL encoding, structured concurrency
- Unknown IETF control message types now skip just the unknown frame
instead of dropping the entire merge buffer (a peer sending a
draft-17 message we don't enumerate — FETCH, GOAWAY, MAX_SUBSCRIBE_ID
— would otherwise wedge the pump). Adds MoqUnknownTypeException
carrying bytesConsumed so runControlPump can advance past it.
- pumpUniStreams + pumpInboundBidis wrap their inner collect in
coroutineScope so per-stream drains are children of the pump's job
(was: launched on the outer scope as siblings, leaking past
cancelAndJoin until the transport's own flow errored out).
- parseEndpoint handles IPv6 authorities ([::1], [2001:db8::1]:4443).
Naive lastIndexOf(':') used to find a colon inside the address.
- buildRelayConnectTarget percent-encodes the namespace path so a
malicious / careless `d` tag containing `?`, `#`, `&`, ` ` etc.
can't truncate the URL and shove the JWT into the wrong slot.
- Reconnect orchestrators (listener + speaker) replace
`runCatching { openOnce / close / startBroadcasting }` with explicit
try/catch that rethrows CancellationException, so cooperative
cancellation from the parent scope dies promptly instead of running
one more iteration after the cancel.
Adds three regression tests:
- parseEndpoint_handles_IPv6_authorities
- buildRelayConnectTarget_percent_encodes_path_unsafe_chars
- unknown_message_type_throws_typed_exception_with_full_frame_size
215 tests pass, 0 failures.

fix(nestsClient): bug + perf fixes from Nests implementation review
- send() now nulls currentGroup and returns false on uni-stream write failure (was: silently returned true while reusing the dead stream) - Subscribe bidi gets a single long-running collector that closes the frames channel on peer FIN / transport tear-down (was: consumer could hang forever on a black-holed UDP path with no Announce(Ended)) - AudioException.Kind gains EncoderError; mic-side encode failures no longer mis-route through DecoderError handlers - MoqCodec.decode bounds the payload-length varint before .toInt() so a peer-driven absurd length can't wedge the parser forever - Publish hot-path framing collapses to a single ByteArray allocation (was: Varint.encode + plus operator, two allocs per Opus frame at 50 fps) - Drops the now-unused readSubscribeResponseFromBidi / readSizePrefixedFromBidiInto / EarlyExit helpers Adds a regression test that asserts the frames flow completes when the peer FINs the subscribe bidi. 213 tests pass, 0 failures. |

nestsClient: expose moq-lite max_latency on subscribeSpeaker + correct plan framing
The moq-lite Lite-03 spec puts subscriber-side group-staleness control in
max_latency on the SUBSCRIBE frame: 0 = unlimited (relay falls back to its
MAX_GROUP_AGE = 30 s default); a positive value tells the relay to evict
groups older than that in favour of newer ones during transient backpressure.
Plumb it through:
NestsListener.subscribeSpeaker(pubkey, maxLatencyMs = 0L)
└─ MoqLiteNestsListener → MoqLiteSession.subscribe(.., maxLatencyMillis)
└─ DefaultNestsListener (IETF) ignores — no equivalent on that wire
└─ ReconnectingHandle re-issues across reconnects
Default stays at 0L for back-compat with the JS reference watcher; callers
opt in for low-latency live audio.
Also rewrites nestsClient/plans/2026-05-01-quic-stream-cliff-investigation.md
with corrected framing: of the four "upstream issues" the prior draft listed,
only our own missing MAX_STREAMS_UNI emission was a real bug (RFC 9000 §4.6
violation, fixed in

fix(nests): publish handles list under AtomicInteger barrier in speaker test
ScriptedSpeaker mutated `handles` AFTER incrementing `_startCount`, so a reader that polled startCount on a different thread (the test runs on the runBlocking thread while the broadcast pump runs on Dispatchers.Default) could see startCount==1 via the volatile AtomicInteger read before the subsequent list write became visible, then fail `assertEquals(1, first.handles.size)` with a stale 0. Also `mutableListOf` itself is not thread-safe — concurrent reads during a write are undefined. Reorder so the list append happens BEFORE the increment (the volatile write now publishes the list mutation under the same happens-before edge tests already rely on for startCount), and swap the backing store for CopyOnWriteArrayList so concurrent reads of `handles[0]` are well-defined. Observed as a flake on Ubuntu CI; passes locally. |

test(nests): fix flaky ReconnectingNestsListenerTest on macOS
`subscribeSpeaker_survives_session_swap` and
`unsubscribe_before_session_swap_releases_handle` had two race
conditions exposed only on macOS scheduling:
1. ScriptedListener.subscribeCount is incremented inside
opener(listener) — BEFORE the wrapper's pump reaches
`handle.objects.collect { frames.emit(it) }`. Waiting on
subscribeCount alone doesn't prove the pump is collecting
from first.frames. An emit upstream before the pump's collect
registers is silently dropped.
2. The wrapper's outer `frames` SharedFlow is replay=0. The
`scope.async { take(2).toList() }` consumer might not have
subscribed by the time the test thread races into the first
emit, dropping the value.
Both are fixed by waiting for actual subscription registration:
- first/second.frames.subscriptionCount.first { it > 0 } — flips
to 1 only after the pump's collect lands, which is strictly
after liveHandleRef.set(handle).
- onSubscription + CompletableDeferred — fires after the
consumer's collector is registered against the SharedFlow.

fix(nests): rotate moq-lite groups + reconnect after publisher cycle
To make a SubscribeHandle survive a publisher session swap on the same relay, three things had to change together: 1. Broadcaster emits one Opus frame per moq-lite group (`publisher.send` + `publisher.endGroup`). moq-lite's "from-latest" subscribe semantics deliver a new subscriber the NEXT group's frames; without per-frame rotation a subscriber that attaches mid-broadcast waits forever for the (single, never-ending) group to end. 2. MoqLiteSession opens its announce-watch bidi synchronously before the first subscribe, dispatches subscribe + announce frames over a single long-running collector (varint type code hoisted outside `collect`), and FINs the publisher's currentGroup when an inbound subscribe bidi closes — so the next send opens a fresh group keyed off the live subscriber instead of the recycled one. 3. ReconnectingNestsListener no longer breaks on terminal=Closed in the orchestrator; the user-driven stop path goes through `orchestrator.cancel()`, so any other Closed (peer-driven transport close, half-broken session, publisher recycle) is a reconnect trigger. Round-trip interop test updated to assert `groupId == idx` (one group per frame) rather than `groupId == 0`. All three reconnecting-listener interop scenarios now pass against the real moq-rs relay: happy-path, session-swap, and listener-survives-publisher-recycle. |

test(nests): fix nextSubscribeBidi helper to terminate after match
The takeWhile/collect pattern only re-checks its predicate when the
NEXT upstream value emits, so once nextSubscribeBidi found its
target Subscribe bidi, the helper sat blocked waiting for a
follow-up bidi that may never come — turning groups_are_demuxed_by_
subscribeId into a 5-minute hang on tests that open exactly two
subscribes (the announce-watch bidi happened to land between, but
relying on it to nudge the flow forward is fragile).
Switched to transformWhile { … emit(…); false }.firstOrNull() so
the upstream collection terminates synchronously after the first
match. Warm-daemon test time drops from multi-minute timeout back
to the expected ~10 ms range.

feat(nests): pulse the speaker ring with live audio level
Adds an end-to-end audio-amplitude pipeline so on-stage speakers' green ring throbs in time with their voice (closer to Spaces / Clubhouse than the previous binary "is in speakingNow" indicator). NestPlayer.play() now takes an onLevel callback and computes the normalized peak of each decoded 16-bit PCM frame. NestViewModel exposes audioLevels: StateFlow<Map<String, Float>>; raw 50 Hz updates from the decode loop are coalesced into a 10 Hz publish tick (LEVEL_TICK_MS) so the StateFlow doesn't spam recompositions across a busy stage. The map is cleared on speaker close, on the speaking-timeout sweep, and on teardown. In MemberCell the speaking ring's width animates between AVATAR_RING_WIDTH (3 dp) and MAX_RING_WIDTH (7 dp) via animateDpAsState, smoothing the tick into a continuous halo. Muted-publisher and idle states are unchanged. Adds NestPlayerTest coverage for the new callback (level math + empty-PCM short-circuit). |

feat(nests): proactive JWT refresh + reconnect for speaker path
Mirror the listener's ReconnectingNestsListener for the publish side. moq-auth issues 600 s bearer tokens; without proactive refresh, a user holding the stage past 10 minutes silently drops when the relay tears down the WebTransport session and stays off the air until they manually re-tap Talk. The new wrapper recycles the session at 540 s so the relay never sees an expired token, and re-issues publishing onto each fresh session with the user's mute intent replayed on the new handle. VM swap is a one-line change to DefaultNestsSpeakerConnector. The caller-owned BroadcastHandle is now the wrapper's stable handle that survives every refresh. Six unit tests cover happy path, refresh-without-failure-state, mute replay across recycle, close idempotence, first-attempt-failure exception propagation, and post-close startBroadcasting guard. https://claude.ai/code/session_01HXf3zG3F2ev2ASeQju7Y5S |

refactor: rename Audio Room → Nest project-wide
Aligns class names, package paths, string resource keys, UI text and intent actions with the Nests branding used by the EGG specs in nestsClient/specs/. Mechanical rename — no behavior change. - Folders: audiorooms/ → nests/ (5 paths across amethyst, quartz) - 30+ class renames (AudioRoom* → Nest*, AudioRooms* → Nests*) - String resource keys audio_room_* → nest_* - UI strings "Audio Room"/"Audio Rooms" → "Nest"/"Nests" (incl. all locales) - Intent extras AUDIO_ROOM_* → NEST_* - Compose route Route.AudioRooms → Route.Nests Spec-aligned identifiers (MeetingSpaceEvent, meetingSpaces/, the nip53* packages) are intentionally untouched — those are NIP-53 protocol names, not "audio room" branding. https://claude.ai/code/session_01RDpuki4t8StSg1CZcXnV5b |

chore(audio-rooms): align catalog/announces error timing + comment (audit #5-7)
* announces() now throws UnsupportedOperationException at CALL
time (not the first collect) on the IETF default — matches
subscribeCatalog's timing so both can be guarded with one
`runCatching { listener.announces() }` per session rather than
a runCatching around every collect site (audit #6).
* KDoc on announces() documents the deliberate hot-vs-cold
asymmetry with subscribeSpeaker/subscribeCatalog: announce
data is room-state with a single VM consumer (cold flow is
sufficient), audio is per-frame playout with multi-collect
resilience needs (hot SharedFlow with DROP_OLDEST). The
different shapes are intentional, not accidental (audit #5).
* MoqLiteNestsListener.wrapSubscription's "IETF SubscribeHandle
path conventionally surfaces" comment was scoped to the audio
track when first written; now the same body serves both audio
and catalog. Re-frame so the comment applies to either track
(audit #7).
Test: NestsListenerCatalogTest's announces-throws case now
asserts the call itself throws, not the collect.

feat(audio-rooms): announce-driven speaker discovery (T4 #17b)
Surface moq-lite's ANNOUNCE flow on NestsListener so the audio
room can render an authoritative "actively broadcasting"
indicator independent of kind-10312 presence's `publishing`
flag. Same channel nostrnests' web client uses for its live
badges (`useRoomAnnouncements` in the JS reference).
Wire-up:
* RoomAnnouncement(pubkey, active) data class — one update
per publisher transition (Active → broadcast came up,
inactive → broadcast went down).
* NestsListener.announces(): Flow<RoomAnnouncement> with a
default body that throws UnsupportedOperationException on
the IETF reference path.
* MoqLiteNestsListener implements via session.announce("")
against the room's namespace; the suffix carries the
speaker pubkey hex straight through.
* ReconnectingNestsListener routes via collectLatest so the
consumer-facing flow restarts against each new session
after a refresh / reconnect (no SubscribeHandle re-issuance
pump needed — announces is a cold per-collect stream).
* AudioRoomViewModel.announcedSpeakers: StateFlow<Set<String>>
populated by observeAnnounces. Active emissions add the
pubkey, inactive emissions remove it. Cleared on teardown.
IETF listeners leave the set empty; UI falls back to
presence's publishingNow flag.
Tests:
* NestsListenerCatalogTest — adds the announces() default-
throws-on-collect case.
Closes the audit's Tier-4 #17b gap. UI integration (e.g. a green
"live" dot driven by announcedSpeakers) is a follow-up — the data
flow is in place and downstream consumers can opt in.

feat(audio-rooms): proactive JWT refresh in the reconnecting wrapper (T4 #16)
moq-auth issues bearer tokens with a 600 s lifetime. When a token
expires the relay tears down the WebTransport session and the
wrapper recovers via the regular Failed → Reconnecting → Connected
path with a brief audible dropout (smoothed by the SubscribeHandle
buffer pump but still user-visible as a Reconnecting chip).
Add `tokenRefreshAfterMs` to connectReconnectingNestsListener
(default 540 s — 1 min before the relay's 600 s expiry). The
orchestrator now waits for either a terminal listener state OR
the refresh deadline; whichever fires first wins. On refresh:
* close the still-healthy listener,
* skip the reconnect-schedule path (refresh is a planned
cutover, not a backoff event),
* loop straight to openOnce() which mints a fresh JWT and
establishes a new session.
The SubscribeHandle re-issuance pump cuts subs over to the new
session, and the wrapper's outward state never enters Reconnecting
during the cutover — the user-facing UI stays Connected end-to-end.
Setting tokenRefreshAfterMs <= 0 disables the behavior.
Tests:
* ReconnectingNestsListenerTest gains
`proactive_token_refresh_recycles_listener_without_failure_state`
— drives the refresh path with a 50 ms window, captures every
state emission, asserts neither Reconnecting nor Failed appear
during a clean recycle.

feat(audio-rooms): subscribeCatalog on NestsListener (moq-lite only)
Surface moq-lite's `catalog.json` track on the NestsListener API.
The catalog publishes one JSON object per group describing the
broadcast (codec, sample rate, optional speaker-side hints) and
is the canonical channel a watcher reads first to discover
available tracks.
Wire-up:
* NestsListener.subscribeCatalog(pubkey) — interface method with
a default body that throws UnsupportedOperationException, so
the IETF DefaultNestsListener fails loud rather than returning
a flow that never delivers data.
* MoqLiteNestsListener overrides it to wrap
`session.subscribe(broadcast = pubkey, track = "catalog.json")`
through the same MoqObject mapping the audio path uses.
* ReconnectingNestsListener routes both subscribeSpeaker and
subscribeCatalog through a shared `reissuingSubscribe` helper —
catalog handles also survive session swaps via the
MutableSharedFlow re-issuance pump.
Tests:
* NestsListenerCatalogTest — verifies the interface default
rejects with UnsupportedOperationException so a caller wired
against the IETF reference path fails fast.
VM/UI consumers (e.g. "speaker codec" tooltip) are intentionally
out of scope for this commit; this exposes the capability so a
follow-up can plug in a JSON parser + per-pubkey catalog cache.

fix(nests-reconnect): break the StateFlow collect + survive session swaps (T4 #2)
Two related bugs in connectReconnectingNestsListener:
1. Orchestrator never advanced past the first Failed. The reconnect
loop used `listener.state.collect { ... return@collect }` to
"exit" on a terminal state, but `return@collect` only returns
from the lambda — a StateFlow's collect keeps running. As a
result, after the first transport failure the orchestrator
re-entered the lambda for every subsequent emission and never
reached the outer `delay(delayMs)` / openOnce() that opens the
next session. Switch to `onEach { mirror } + first { terminal }`
so the upstream completes deterministically.
2. SubscribeHandle stopped emitting after a reconnect (the
long-deferred Tier-4 follow-up). Reissue the subscription on
every activeListener swap by feeding a wrapper-side
MutableSharedFlow from a `collectLatest` pump that re-calls
`listener.subscribeSpeaker(...)` against each fresh session.
The buffer (64 frames ≈ 1.3 s of Opus) covers a typical
re-handshake without dropping speech. Unsubscribing the
logical handle cancels the pump and forwards a best-effort
unsubscribe to the live underlying handle.
Tests: ReconnectingNestsListenerTest covers both happy-path
session swap (frames keep arriving) and the unsubscribe-before-swap
path. Uses real coroutines + Dispatchers.Default rather than
runTest because the test scheduler doesn't auto-advance the
StateFlow + delay chain reliably under UnconfinedTestDispatcher.

feat(audio-rooms): NestsReconnectPolicy + Reconnecting state (T4 #2 foundation)
Lays the foundation for the moq-lite reconnect-with-backoff path:
NestsReconnectPolicy — exponential backoff settings.
(initial=1s, multiplier=2, max=30s) by
default, mirroring kixelated/moq's JS
reference (`delay: { initial: 1000,
multiplier: 2, max: 30000 }`).
maxAttempts defaults to Int.MAX_VALUE
since a long-running room should keep
trying as long as the user hasn't left;
the Composable's onDispose is the cancel
signal.
NoRetry sentinel for first-shot-or-fail
tests / single-room demos.
delayForAttempt(n) — 1-indexed; doubles per attempt; clamps at
maxDelayMs. n<1 returns 0.
isExhausted(n) — n >= maxAttempts (next retry forbidden).
init { require(...) } — ctor guards reject zero/negative initial,
multiplier <= 1, max < initial, attempts < 1.
NestsListenerState.Reconnecting / NestsSpeakerState.Reconnecting
— new state variants with (attempt, delayMs). UI consumes via
the existing NestsListenerState → ConnectionUiState mapper which
surfaces Reconnecting under OpeningTransport for the v1 chip;
a future commit can add a dedicated "Attempt N in Mms" UI.
Tests:
* First attempt = initialDelayMs
* Doubling via attempt index until maxDelayMs ceiling
* Non-standard multiplier still respects ceiling
* Zero/negative attempt → 0 delay
* isExhausted at the boundary
* NoRetry exhausts after attempt 1
* Constructor rejects invalid inputs
The orchestration layer (mint-fresh-JWT → reopen WT → re-issue
SubscribeHandles + the speaker-side equivalent) is the heavier
follow-up. Deliberately split because:
1. The state + policy can ship and be consumed by callers ready
to handle Reconnecting today — no behaviour change for those
who don't.
2. The full session-resurrection path needs `MutableSharedFlow`
buffering per SubscribeHandle so app code's `Flow<MoqObject>`
doesn't notice the swap. Substantial refactor; better as its
own commit with its own tests.

fix(audio-rooms): SubscribeResponse framing matches moq-lite-03
Lite-03's SubscribeResponse on the response side of a Subscribe bidi
is two pieces concatenated:
type varint (0 = Ok, 1 = Drop)
body size-prefixed bytes
The type discriminator sits OUTSIDE the body's size prefix. Earlier
drafts wrapped the whole thing in one outer size prefix; Lite-03 split
them. See `rs/moq-lite/src/lite/subscribe.rs::SubscribeResponse::encode`
(the `_` arm, which matches Lite-03+).
Our codec was producing — and reading — the older outer-wrapped form,
so against a Lite-03 relay we mis-parsed the type discriminator (`0`
for Ok) as a "size=0" outer prefix and surfaced a confusing
`MoqCodecException: truncated varint at offset=0 (remaining=0)` from
inside `decodeSubscribeResponse`. The first byte the relay sent was
the type, not a size, and our reader peeled it off as the outer length.
Fix touches three pieces:
* `encodeSubscribeOk` / `encodeSubscribeDrop` emit
`type + size_prefixed(body)` directly (no outer wrap), via a small
`prefixWithType` helper.
* `decodeSubscribeResponse` reads `type` then a length-prefixed body,
decodes the body in its own reader, and asserts the outer payload
is fully consumed.
* `readSubscribeResponseFromBidi` walks chunks into the buffer until
both the type varint and the size-prefixed body have arrived, then
re-emits the contiguous `[type][size][body]` slab so the decoder
parses it self-contained. Reuses the `EarlyExit` collector pattern
the publisher-inbound path already uses; avoids `Flow.iterator()`
which doesn't exist in kotlinx.coroutines.
Tests:
* `MoqLiteCodecTest::subscribe{Ok,Drop}_round_trips` no longer
`peelSizePrefix` the encoded bytes — the new wire form has no outer
prefix to strip; the bytes go straight through `decodeSubscribeResponse`.
* `MoqLiteSessionTest::publisher_acks_subscribe_and_pushes_group_data_on_uni_stream`
also drops `MoqLiteFrameBuffer().readSizePrefixed()` on the ack chunk
for the same reason.
Verified end-to-end against a bare-metal moq-relay 0.10.25 + moq-auth
(`-DnestsInteropExternal=true`):
* `NostrNestsRoundTripInteropTest::production_speaker_broadcasts_to_production_listener_via_real_relay`
passes — speaker → listener → 8 frames round-trip cleanly.
* `NostrNestsMultiPeerInteropTest::one_speaker_fans_out_to_two_listeners`
passes — same speaker reaches both listeners with the full frame
stream.
* The `listener_subscribed_before_announce_receives_late_frames` and
`two_speakers_in_same_room_deliver_independently_to_one_listener`
cases still fail with `subscribe stream FIN before reply` — those
are different relay-behavior issues (the v1 relay seems to FIN
subscribes against unannounced broadcasts and against a second
speaker on the same listener), unrelated to the codec.

feat(audio-rooms): moq-lite speaker side end-to-end (phase 5c-speaker)
Production speaker path now runs on moq-lite, so connectNestsSpeaker
exchanges real moq-lite framing with the nostrnests reference relay.
Transport layer:
- WebTransportSession.incomingBidiStreams() — peer-initiated bidi
flow. moq-lite publishers receive Announce + Subscribe bidis from
the relay (rs/moq-lite/src/lite/publisher.rs:40 uses
Stream::accept(session)), so the abstraction grew the
accept-bidi-from-peer surface.
- WebTransportSession.openUniStream() — locally-opened uni stream
for group push (rs/moq-lite/src/lite/publisher.rs:338 uses
session.open_uni()).
- :quic WtPeerStreamDemux StrippedWtStream now carries optional
send/finish closures. The demux takes the QuicConnectionDriver
so wakeups fire after each app-level write on a peer-initiated
bidi.
- FakeWebTransport now exposes incomingBidiStreams + openUniStream
directly; the openPeerUniStream test helper went away (production
flow covers it).
Session layer:
- MoqLiteSession.publish(suffix) — claims a broadcast suffix and
lazily launches a relay→us bidi pump. ControlType=Announce reads
AnnouncePlease, replies Active(suffix). ControlType=Subscribe reads
body, replies SubscribeOk, registers the inbound subscription.
- MoqLitePublisherHandle — startGroup / send / endGroup / close
semantics. send opens a uni stream per group with DataType=0 +
GroupHeader and pushes varint(size)+payload frames. close emits
Announce(Ended) on every active announce bidi, FINs the uni.
Application layer:
- AudioRoomMoqLiteBroadcaster — sibling of AudioRoomBroadcaster but
drives MoqLitePublisherHandle (keeps IETF broadcaster intact for
its unit tests).
- MoqLiteNestsSpeaker — NestsSpeaker adapter, mirror of
MoqLiteNestsListener on the publish side.
- connectNestsSpeaker now opens a MoqLiteSession (no SETUP) and
returns MoqLiteNestsSpeaker.
Tests:
- 4 new MoqLiteSessionTest cases:

feat(audio-rooms): connectNestsListener uses moq-lite (phase 5d)
Production wiring switch — `connectNestsListener` now opens a
moq-lite (Lite-03) session against the WebTransport peer instead of
running the IETF MoQ-transport SETUP handshake. The downstream
NestsListener interface is unchanged; consumer code in commons /
amethyst keeps working.
Listener flow (per the audio-rooms NIP draft + nostrnests JS reference):
- subscribeSpeaker(pubkey) → MoqLiteSession.subscribe(broadcast =
pubkey, track = "audio/data")
- frames map to MoqObject so AudioRoomPlayer / AudioRoomViewModel
keep working unchanged. Per-frame `objectId` is synthesised as a
monotonic counter (moq-lite has no per-frame ID); `groupId` =
moq-lite group sequence; `trackAlias` = subscribe id.
NestsListenerState.Connected.negotiatedMoqVersion now reports
MOQ_LITE_03_VERSION (a synthetic constant carrying the ALPN suffix
in the low bytes) since moq-lite has no in-band SETUP message.
NestsConnectTest:
- Drop the SETUP-faking peer side — moq-lite has no SETUP, so
connectNestsListener returns Connected immediately after the WT
handshake.
- Assert MOQ_LITE_03_VERSION on Connected.
Speaker path (`connectNestsSpeaker`) is untouched — it still uses
the IETF DefaultNestsSpeaker. Speaker-side moq-lite needs
`acceptBidiStream` on the WebTransportSession interface so the relay
can open Announce/Subscribe bidis to the publisher; tracked in
plans/2026-04-26-moq-lite-gap.md phase-5c-speaker.
Verified `:commons:compileKotlinJvm` + `:amethyst:compilePlayDebugKotlin`
both still compile against the swap.

feat(audio-rooms): MoqLiteSession listener-side (phase 5c-listener)
Listener-side moq-lite (Lite-03) session that wraps a
WebTransportSession and exposes:
- announce(prefix) — opens an Announce bidi with
ControlType=Announce + AnnouncePlease(prefix), surfaces a flow
of relay Announce updates (Active/Ended)
- subscribe(broadcast, track, ...) — opens a Subscribe bidi with
ControlType=Subscribe + body, reads the size-prefixed response,
returns a MoqLiteSubscribeHandle whose frames flow yields each
frame the publisher pushes
- close() — cancels pumps, FINs every active subscribe bidi
(moq-lite UNSUBSCRIBE is "FIN the bidi"), closes the transport
Group demux: a single inbound-uni-stream pump per session reads the
DataType byte (Group=0) + size-prefixed group header, then routes
each subsequent (size, payload) frame to the matching
subscriptionsBySubscribeId entry's frame channel.
Speaker side stops at the announce/subscribe interface — moq-lite
publisher flows depend on accept_bi() / server-initiated bidi
streams (see clarifying agent summary in plans/2026-04-26-moq-lite-gap.md).
That's a follow-up; the WebTransportSession interface needs an
acceptBidiStream() method first.
FakeWebTransport.openPeerUniStream() — new helper so tests can
inject group data from the peer side without going through the
session's outbound uni stream API.
Tests in MoqLiteSessionTest — runBlocking-based (not runTest) so
real-time channel coordination works without virtual-time
artifacts:
- subscribe_writes_request_and_returns_handle_on_ok
- subscribe_throws_on_drop_response
- announce_streams_relay_updates
- groups_are_demuxed_by_subscribeId (no cross-talk)
- unsubscribe_FINs_the_subscribe_bidi

feat(audio-rooms): moq-lite codec primitives + message types (phase 5a/5b)
First two phases of the moq-lite (Lite-03) implementation per
nestsClient/plans/2026-04-26-moq-lite-gap.md. No production wiring
yet — the production helpers still call the IETF MoqSession.
What landed:
- MoqLitePath — mandatory wire-boundary normalisation (strip
leading/trailing/duplicate `/`), join, path-component-aware
stripPrefix. Mirrors rs/moq-lite/src/path.rs semantics.
- MoqLiteAlpn / MoqLiteControlType / MoqLiteDataType /
MoqLiteAnnounceStatus / MoqLiteSubscribeResponseType — wire
enums for ALPN ("moq-lite-03"), per-bidi ControlType varints,
Group uni-stream type byte, announce status, subscribe
response type.
- Message data classes — AnnouncePlease, Announce, Subscribe,
SubscribeOk, SubscribeDrop, GroupHeader, Probe.
- MoqLiteCodec — encode/decode for each message, with the
size-prefix envelope baked in. Handles the off-by-one
`0 = None, n = Some(n−1)` trick for startGroup/endGroup,
coerces booleans to 0/1, validates priority fits in u8,
rejects unknown status/response bytes. Path normalisation
applied at every encode + decode boundary.
- MoqLitePathTest, MoqLiteCodecTest — round-trip tests for
every codec entry point + negative paths (oversized priority,
invalid ordered byte, unknown status, trailing garbage).
All MoqWriter / MoqReader / MoqCodecException primitives reused
from the IETF MoQ codec — same varint and length-prefix shapes.

test/refactor(audio-rooms): nostrnests wire-shape fixes + interop expansion (phase 4)
Wire-shape corrections discovered while scoping the interop test suite
against the real moq-rs relay:
1. WebTransport CONNECT path is now /<moqNamespace> (matches the
relay's claims.root prefix check). Previously hardcoded "/anon".
2. JWT travels in the ?jwt=<token> query parameter, not the
Authorization header — moq-rs only reads the query param. The
bearer-token path on QuicWebTransportFactory is now unused for
nests; left in place for non-nests WebTransport servers.
3. Harness `moqEndpoint` is the relay base URL only; the connect
helpers append /<namespace>?jwt=<token> themselves.
Interop test additions (all -DnestsInterop=true gated, default-skipped):
- NostrNestsAuthFailureInteropTest — locks in the moq-auth sidecar's
rejection paths (missing/wrong-scheme Authorization, NIP-98 signed
for the wrong URL, malformed namespace per the strict regex,
publish=true grant for any caller — sidecar does NOT gate by NIP-53
hostlist).
- NostrNestsAuthEndpointsInteropTest — /health, /.well-known/jwks.json
shape (must contain ES256/P-256), 404 on unknown route.
- NostrNestsMultiPeerInteropTest — multi-listener fan-out, multi-
speaker isolation, subscribe-before-announce. Code is wired through
production connectNestsSpeaker / connectNestsListener; will pass
once the moq-lite gap (below) is resolved.
Major finding documented in nestsClient/plans/2026-04-26-moq-lite-gap.md:
nostrnests's stack uses moq-lite (kixelated's variant), NOT IETF
draft-ietf-moq-transport which `:nestsClient` currently implements. The
two are wire-incompatible — single-string broadcast/track names vs. byte
tuples, different ANNOUNCE/SUBSCRIBE framing. The wire-shape fixes here
make the WebTransport CONNECT itself succeed, but the post-CONNECT MoQ
framing layer still needs a moq-lite codec before round-trip / multi-peer
tests can pass against real nests. Pursued as a separate phase.

refactor(audio-rooms): NestsClient API matches nostrnests reality (phase 2/3)
The Phase-1 interop harness exposed a substantial mismatch between our
production HTTP client and what the nostrnests reference server actually
exposes. This commit refactors `:nestsClient` and the wiring above it so
the production code path can talk to a real moq-auth + moq-relay.
| Aspect | Before | After (matches nostrnests/moq-auth/src/index.ts) |
|-----------|-------------------------------------------|--------------------------------------------------|
| Method | GET | POST |
| URL | `<base>/<roomId>` | `<base>/auth` |
| Body | none | `{"namespace":"nests/<kind>:<host>:<roomId>","publish":bool}` |
| Response | `{endpoint, token, codec, sample_rate}` | `{token}` only |
| Endpoint | from response | from event's `endpoint` tag (passed via `NestsRoomConfig.endpoint`) |
| NIP-98 | bound to GET URL | bound to POST URL + body hash |
Type changes:
- New `NestsRoomConfig` data class bundling (authBaseUrl, endpoint,
hostPubkey, roomId, kind). Built by the caller (UI / VM) from the
NIP-53 kind 30312 event before invoking connectNests*.
- `NestsRoomConfig.moqNamespace()` produces the exact format
moq-auth's NAMESPACE_REGEX expects: `nests/<kind>:<hex64>:<roomId>`.
- `NestsRoomInfo` deleted; replaced with a tiny `NestsTokenResponse(token)`
matching the real response shape.
- `NestsClient.resolveRoom(serviceBase, roomId, signer): NestsRoomInfo`
→ `NestsClient.mintToken(room, publish, signer): String`. The
publish flag drives the JWT claims (`get` for listeners, `put`
for speakers).
Wire path:
- `OkHttpNestsClient` now POSTs `<authBase>/auth` with a JSON body
and a NIP-98 Authorization header bound to (POST, url, body-hash).
- `connectNestsListener` / `connectNestsSpeaker` take `room:
NestsRoomConfig` instead of split (serviceBase, roomId), pass
`publish=false` / `publish=true` respectively, and use the room's
`endpoint` (not a server-returned one) for the WebTransport
connect. The minted JWT is the bearer token.
- `NestsListenerState.Connected` / `NestsSpeakerState.Connected` /
`Broadcasting` carry the `room: NestsRoomConfig` instead of the old
`roomInfo: NestsRoomInfo`.
- MoQ TrackNamespace for the room is now a single segment whose
bytes are `room.moqNamespace()` — the simplest mapping to the
relay's JWT claim check (`root: "<namespace>"`); Phase-3 round-trip
test will confirm and adjust if the relay expects a multi-segment
tuple.
Wiring above:
- `AudioRoomViewModel` constructor: replaces `(serviceBase, roomId)`
with `(room: NestsRoomConfig)`. Connector seam interfaces
(NestsListenerConnector, NestsSpeakerConnector) follow the same
shape.
- `AudioRoomViewModelFactory` (Android) takes `room: NestsRoomConfig`.
- `AudioRoomActivity` adds `EXTRA_AUTH_BASE_URL`, `EXTRA_ENDPOINT`,
`EXTRA_HOST_PUBKEY`, `EXTRA_KIND` Intent extras (was just service
+ roomId) and reconstructs `NestsRoomConfig` in onCreate. Drops
`EXTRA_SERVICE_BASE`.
- `AudioRoomJoinCard` reads `event.endpoint()` + `event.pubKey` +
`event.kind` in addition to `event.service()`; rooms missing any
of those are silently un-joinable (the event author didn't host
on a nests-compatible relay).
- `AudioRoomActivityContent` takes `room: NestsRoomConfig` in place
of (serviceBase, roomId) and threads it down.
Phase-1 ping test rewired to use the production `OkHttpNestsClient`
end-to-end against the real `/auth`, asserting we get back a
3-segment JWT.
Existing in-process tests updated for the new types: NestsConnectTest,
NestsSpeakerTest, AudioRoomViewModelTest. NestsRoomInfoTest renamed to
NestsRoomConfigTest with new cases for the namespace formatter and the
auth-URL helper. All 80 in-process tests still green.
Phase 3 (next) will add the full round-trip interop test that runs
production `connectNestsListener` + `connectNestsSpeaker` through the
real moq-relay — that's where MoQ wire-format assumptions (draft
revision, OBJECT_DATAGRAM layout, namespace tuple shape) get verified
or get followup audit findings.

test(audio-rooms) + fix: round-trip test + audit pass
Adds an end-to-end MoQ round-trip test and lands the highest-severity
findings from a 3-agent audit (protocol / ViewModel / Android lifecycle)
of the M5–M7 + Activity work.
Round-trip test (`:nestsClient` MoqRoundTripTest):
- Two MoqSession.client() instances (publisher + subscriber) talk
through a hand-rolled in-test relay coroutine that mirrors a real
MoQ relay's wire behavior (forwards CLIENT_SETUP / SERVER_SETUP /
ANNOUNCE / SUBSCRIBE / SUBSCRIBE_OK / OBJECT_DATAGRAM).
- 100-Opus-frame test exercises the full publisher → wire →
subscriber path, asserting payload bytes + monotonic group/object
ids round-trip correctly. Catches any drift between our publisher
and our own subscriber's wire format.
- Second test verifies SUBSCRIBE_ERROR(TRACK_DOES_NOT_EXIST) flows
back as MoqProtocolException when the publisher hasn't openTrack'd.
MoQ protocol fixes (CRITICAL audit findings):
- SubscribeDoneStatus constants were inverted: had UNSUBSCRIBED=0x01
(peer reads as INTERNAL_ERROR) and TRACK_ENDED=0x00 (peer reads as
UNSUBSCRIBED). Swapped to draft-stable values: UNSUBSCRIBED=0x00,
TRACK_ENDED=0x03.
- Pending CompletableDeferreds for in-flight SUBSCRIBE / ANNOUNCE on
session close were `cancel()`-ed, which propagates as
CancellationException — caller's entire scope cancels instead of
catching a domain MoqProtocolException. Switched all sites to
`completeExceptionally(MoqProtocolException("session closed"))`
including unsubscribe-while-pending-OK.
ViewModel fixes:
- openSubscription race: re-check `activeSubscriptions[pubkey] === slot
&& !closed` AFTER the suspending `subscribeSpeaker` returns; if the
user removed the speaker mid-flight, fire-and-forget UNSUBSCRIBE
rather than attaching a leaked SubscribeHandle + AudioRoomPlayer to
a discarded slot.
- Server-initiated `Closed` listener state now triggers
`teardown(targetState=Closed)` and resets the auto-retry counter,
so a transport-died-mid-handshake doesn't leave stale subscriptions
in the VM map until the Activity finishes.
- Cleanup-scope split: `disconnect()` (user-driven) routes the close
through `viewModelScope` (still alive); `onCleared()` routes it
through a process-lived `cleanupScope` (default GlobalScope, tests
pass backgroundScope) so MoQ control frames (UNSUBSCRIBE,
UNANNOUNCE, SUBSCRIBE_DONE) actually land before the QUIC
transport drops, instead of being eaten by the cancelled
viewModelScope.
Android lifecycle fixes:
- AudioRoomBridge.clear() wired into AccountViewModel.onCleared next
to the existing CallSessionBridge.clear() — no more cross-account
AccountViewModel leak after logout/switch.
- registerReceiver flag now gated on Build.VERSION.SDK_INT
TIRAMISU+ — RECEIVER_NOT_EXPORTED on pre-33 devices collides with
RECEIVER_VISIBLE_TO_INSTANT_APPS. PendingIntents stay
package-scoped via setPackage(packageName).
- onUserLeaveHint no longer enters PIP unconditionally: gated on
ui.connection == Connected AND PackageManager
FEATURE_PICTURE_IN_PICTURE present, so PIP-from-lobby /
PIP-on-incompatible-device doesn't leave a frozen full-screen
card in Recents.
- Replaced the process-wide singleton AudioRoomPipActions toggle
Boolean with a per-Activity MutableSharedFlow<Unit> so a stale
emission from a torn-down Activity can't leak into a new one.
ViewModel test was extended with `cleanupScope = backgroundScope`
plumbing so the post-disconnect `listener.close()` assertion remains
observable in the test scheduler.
Verified: spotlessApply clean; :commons:jvmTest (9 tests),
:nestsClient:jvmTest (80 tests including 2 new round-trip), and
:amethyst:compilePlayDebugKotlin all green.
Audit findings deferred to follow-up commits (none ship-blocking):
- Wire layout pinning vs draft-17 vs draft-11 (currently emits a
draft-11-style OBJECT_DATAGRAM; we advertise draft-17). Resolve
via the M4 manual interop pass against nostrnests.
- UNANNOUNCE racing inbound SUBSCRIBE; control-pump cancel half-write
(audit MoQ #5, #6) — small ordering tweaks.
- Two retry coroutines stacking under fast Failed bursts (audit VM #4).
- AudioRoomForegroundService startForeground always-first contract
(audit Android #8).

feat(audio-rooms): M6 + M7 — AudioRoomBroadcaster + NestsSpeaker API
M6 (AudioRoomBroadcaster): Inverse of AudioRoomPlayer. Pulls PCM frames
from an AudioCapture, runs them through an OpusEncoder, and pushes the
resulting Opus packets into a MoqSession.TrackPublisher as
OBJECT_DATAGRAMs. setMuted keeps the capture + encoder running so unmute
is sample-accurate; encode failures are reported via onError but don't
tear the loop down.
M7 (NestsSpeaker): Mirror of NestsListener for the host / speaker path.
- `NestsSpeaker.startBroadcasting()` — sends ANNOUNCE for the room's
namespace (`["nests", roomId]`), opens a TrackPublisher named after
this user's pubkey hex, wires an AudioRoomBroadcaster onto it.
- `BroadcastHandle.setMuted` / `close()` — speaker-side equivalents of
the listener's mute / disconnect controls.
- `NestsSpeakerState` sealed hierarchy (Idle / Connecting{step} /
Connected / Broadcasting{isMuted} / Failed / Closed).
- `connectNestsSpeaker` orchestration mirrors `connectNestsListener`
end-to-end (HTTP → WebTransport → MoQ setup), then returns a
`DefaultNestsSpeaker` ready for `startBroadcasting`.
Tests:
- AudioRoomBroadcasterTest (5 tests): pcm-flow ordering, mute behavior,
encoder warmup skip, encode-error tolerance, idempotent stop.
- NestsSpeakerTest (2 tests): start/mute/close state transitions,
double-start rejection.
Bug caught + fixed during M7 testing: `DefaultNestsSpeaker.close()`
held its `gate` mutex while calling `handle.close()` which then called
back through `parent.broadcastClosed()` → self-deadlock. Fixed by
making `broadcastClosed` lockless (StateFlow updates are atomic; the
activeHandle compare-and-set is benign under the gate's exclusion of
concurrent startBroadcasting calls).
Verified: `:nestsClient:jvmTest` (78 tests, all green) +
`./gradlew spotlessApply` clean.

feat(audio-rooms): M5 MoQ publisher path — ANNOUNCE + inbound SUBSCRIBE + OBJECT emit
Lifts MoqSession from listener-only to bidirectional. A session can now
ANNOUNCE a track namespace, register one TrackPublisher per track name
under it, accept inbound SUBSCRIBEs from the peer, and emit
OBJECT_DATAGRAMs that fan out to every attached subscriber. This is what
the speaker / host path needs in nests — phases M6/M7 layer audio
capture + a NestsSpeaker API on top.
Public API additions:
- `MoqSession.announce(namespace, parameters)` — sends ANNOUNCE, awaits
ANNOUNCE_OK, returns an `AnnounceHandle`.
- `AnnounceHandle.openTrack(name)` — registers a `TrackPublisher` for a
track under the announced namespace. Idempotent insert is rejected.
- `TrackPublisher.send(payload)` — encodes one MoQ OBJECT_DATAGRAM and
emits it to every currently-attached subscriber. Group id is fixed at
zero per the audio-rooms NIP draft; object ids are monotonic.
- `TrackPublisher.close()` — sends SUBSCRIBE_DONE to attached
subscribers, removes the track from its parent announce.
- `AnnounceHandle.unannounce()` — sends UNANNOUNCE on the wire, closes
every registered publisher.
- `ErrorCode.TRACK_DOES_NOT_EXIST` and `SubscribeDoneStatus.{TRACK_ENDED,
UNSUBSCRIBED}` constants for the SUBSCRIBE_ERROR / SUBSCRIBE_DONE
values we emit.
Internal additions:
- `pendingAnnounces` keyed by namespace, mirroring the existing
`pendingSubscribes` pattern.
- `announces` map tracking live publishers per namespace.
- `inboundSubscribers` + `publisherSubscribers` so the control-pump can
fan an inbound SUBSCRIBE to the right TrackPublisher and so
TrackPublisher.send can snapshot subscribers without per-OBJECT
locking.
- Control pump now routes ANNOUNCE_OK / ANNOUNCE_ERROR (publisher-side
ack) and inbound SUBSCRIBE / UNSUBSCRIBE (we're being asked to send
OBJECTs, or stop). Unknown-track SUBSCRIBE replies with
SUBSCRIBE_ERROR(TRACK_DOES_NOT_EXIST) so the peer doesn't hang.
- `close()` propagates session death into every AnnounceHandleImpl /
TrackPublisherImpl so any in-flight `send` short-circuits cleanly.
All shared-state mutation is funneled through the existing `stateMutex`
(no `synchronized` — that's JVM-only and would break commonMain). The
session-wide `writeMutex` continues to serialize control-stream writes.
Tests (new in MoqSessionTest):
- announce → ANNOUNCE_OK happy path; UNANNOUNCE wire frame on close.
- ANNOUNCE_ERROR surfaces as MoqProtocolException.
- End-to-end: announce + openTrack + peer SUBSCRIBE → SUBSCRIBE_OK +
three OBJECT_DATAGRAMs round-trip with intact group/object ids.
- send() returns false when no subscribers are attached (no buffering).
- Inbound SUBSCRIBE for unknown track under an announced namespace
replies SUBSCRIBE_ERROR.
Verified: `:nestsClient:jvmTest` (12 tests, 0 failures) + `:quic:jvmTest`
(green) + `./gradlew spotlessApply` clean.

feat(audio-rooms): M1 listener-only wire-up — Connect button + Connected chip + mute
Wires `connectNestsListener` into the existing NIP-53 audio-room "stage" so
a user can tap Connect, see the live connection state, and hear hosts
speaking. Per the audio-rooms completion plan
(`nestsClient/plans/2026-04-26-audio-rooms-completion.md`) phase M1.
UI (amethyst):
- AudioRoomStage gets a state-chip / Connect / Disconnect / Mute row
above the existing hand-raise. State chip walks ResolvingRoom →
OpeningTransport → MoQ-handshake → Connected; Failed surfaces the
reason inline with a Retry button. The 30312 `service` tag drives
visibility — rooms hosted on non-nests servers show "Audio not
available" and the rest of the stage UI continues to work.
ViewModel (commons):
- New `AudioRoomViewModel` in commons/.../viewmodels/ owns one
`NestsListener` and one `AudioRoomPlayer` per active speaker, exposes
a single `StateFlow<AudioRoomUiState>`, and reconciles subscriptions
whenever the screen pushes a new speaker set via `updateSpeakers`.
Audio-pipeline construction is injected via `decoderFactory` /
`playerFactory` so a future desktop port can reuse the orchestration
once Compose Desktop has WebTransport. Unit-tested with a fake
`NestsListenerConnector` driving state transitions directly.
nestsClient:
- `AudioPlayer.setMuted(Boolean)` joins the interface; `AudioTrackPlayer`
routes it through `AudioTrack.setVolume(0f/1f)`. Mute keeps the
decode + network pipeline running so unmute is sample-accurate.
Build:
- `:commons` commonMain now `implementation(project(":nestsClient"))` so
the shared VM can see `NestsListener` / `AudioRoomPlayer` / interfaces.
Concrete OkHttp / Quic / MediaCodec / AudioTrack actuals stay in
`:nestsClient`'s platform source sets and are bound by an
Android-side `AudioRoomViewModelFactory` co-located with the screen.
Verified: `./gradlew spotlessApply :commons:jvmTest :nestsClient:jvmTest
:quic:jvmTest :amethyst:compilePlayDebugKotlin` all green.

feat(quic): Phase A — module foundations
Create the new :quic Gradle module (KMP, api(project(":quartz"))) and migrate
the QUIC varint codec out of :nestsClient where it was incidentally living.
Add the connection-ID, packet-number-space, and UDP socket primitives that
the rest of the QUIC client will build on.
Layer-by-layer plan in docs/plans/2026-04-22-pure-kotlin-quic-webtransport-plan.md.
- New :quic module wired into settings.gradle, with commonMain + jvmAndroid
source sets mirroring :quartz's structure.
- Varint moves from com.vitorpamplona.nestsclient.moq to com.vitorpamplona.quic;
MoqBuffer/MoqCodec updated to import the new path.
- ConnectionId enforces the 0..20 byte length range and ships a randomizer
backed by Quartz's RandomInstance.
- PacketNumberSpaceState tracks per-space outbound allocation + largest-received
tracking, and implements the RFC 9000 §A.3 truncated-PN decode formula plus
the §17.1 minimum encode-length picker.
- UdpSocket is an expect class with a connected DatagramChannel actual on
jvmAndroid using Dispatchers.IO (no Selector — one socket per connection).
All 12 tests pass on jvmTest. RFC 9000 §A.1 varint vectors and §A.3 truncated-PN
vector match bit-for-bit.

feat(nestsClient): MoQ ANNOUNCE family + Opus encoder + AudioRecord capture
Phase 4 (codec + audio capture slice). Adds the publisher-side MoQ
control messages and the Opus encode + microphone capture pieces a
speaker needs. The host-grants-speaker UI flow is deferred — that's
multi-screen UX that should be designed before being implemented.
commonMain (nestsclient.moq):
- 5 new MoqMessageType entries with codec round-trip + tests:
* Announce (0x06): publisher offers a track namespace.
* AnnounceOk (0x07): subscriber acknowledges.
* AnnounceError (0x08): subscriber rejects with error code +
reason phrase.
* Unannounce (0x09): publisher withdraws a previously-announced
namespace.
* SubscribeDone (0x0B): publisher tells the subscriber no more
objects are coming for this subscription, with stream count and
reason.
commonMain (nestsclient.audio):
- New `OpusEncoder` interface — symmetric to `OpusDecoder`, one
instance per outgoing track since Opus state is per-stream.
- New `AudioCapture` interface — `start()`, `readFrame()` returns a
PCM frame or null when stopped, `stop()` releases the mic.
androidMain (nestsclient.audio):
- `MediaCodecOpusEncoder` — wraps `MediaCodec("audio/opus")` encoder
variant (API 29+). 48 kHz mono in, 32 kbit/s VBR Opus out, 20 ms
frames. Drains output queue per encode call.
- `AudioRecordCapture` — wraps `AudioRecord` from
`MediaRecorder.AudioSource.VOICE_COMMUNICATION` so the platform's
echo-cancellation + noise-suppression filters apply when available.
Reads exactly one PCM frame per readFrame() call, retries on
underrun, throws AudioException(DeviceUnavailable) on permission/
resource failures.
commonTest:
- `AnnounceCodecTest` — 7 cases covering each message round-trip,
concatenated decode in sequence, and a guard against accidentally
reordering MoqMessageType enum codes.
Permission already declared:
- `RECORD_AUDIO` is already in amethyst/AndroidManifest.xml — no
manifest change needed.
What this does NOT include:
- A publisher loop class (analogous to AudioRoomPlayer for publish
direction) — can be added when the speak-button wiring lands.
- The host-grants-speaker UI — needs design input.
- STREAM_HEADER_SUBGROUP for stream-based object delivery — datagrams
cover the listener happy-path; streams add reliability that nests
may or may not require.

feat(nestsClient): NestsListener facade + connect orchestrator
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.

feat(nestsClient): listener audio pipeline (Opus decode + AudioTrack)
Phase 3d-1 of the Clubhouse/nests integration. Adds the listener-side
audio pipeline that turns a SubscribeHandle's Flow<MoqObject> into
audible PCM through Android's MediaCodec + AudioTrack. Encoder /
AudioRecord (speaker publishing) lands in Phase 4.
commonMain (nestsclient.audio):
- `AudioFormat` constants — 48 kHz mono signed-16-bit, 20 ms frames
(960 samples), matching the nests Opus profile.
- `OpusDecoder` interface — stateful per-track decoder.
- `AudioPlayer` interface — start/enqueue/stop, suspend on backpressure.
- `AudioRoomPlayer` — wires a Flow<MoqObject> through OpusDecoder into
AudioPlayer. Decoder errors are surfaced via an `onError` callback
but don't tear down the loop (one bad packet shouldn't kill the
room); player errors are fatal. play()/stop() are single-shot per
instance, with stop() idempotent and double-release-safe.
- `AudioException` with three canonical kinds (DecoderError,
DeviceUnavailable, PlaybackFailed).
androidMain:
- `MediaCodecOpusDecoder` — wraps `MediaCodec("audio/opus")` with the
RFC 7845 §5.1 Opus identification header in csd-0 and zeroed
pre-skip / seek-pre-roll in csd-1 / csd-2. Drains the output queue
per-packet, handles INFO_OUTPUT_FORMAT_CHANGED gracefully.
- `AudioTrackPlayer` — wraps `AudioTrack` in MODE_STREAM with USAGE_
VOICE_COMMUNICATION / CONTENT_TYPE_SPEECH so the OS treats audio-
room playback like a phone call (call-volume rocker, ducks
notifications). Buffer = 4× minimum so the producer can fall behind
~80 ms (roughly the WebTransport datagram jitter on mobile).
Tests (commonTest, fake-based):
- `AudioRoomPlayerTest` — 7 cases covering happy-path decode +
enqueue, decoder failure with continued loop, stop idempotency,
double-play rejection, play-after-stop rejection, empty-PCM
skip-enqueue, and live channel-backed flow.
The real MediaCodec / AudioTrack code is thin glue against Android
APIs and is validated manually on device — no Robolectric here, the
seams are the Fake* doubles.
Next: Phase 3d-2 wires NestsClient end-to-end (HTTP auth → MoqSession
listener subscribe → AudioRoomPlayer) plus the Amethyst-side
AudioRoomViewModel. After that the only remaining pure-MoQ work is
the Kwik handshake (Phase 3b-2).

feat(nestsClient): MoQ session pump + subscribe API
Phase 3c-3 of the Clubhouse/nests integration. Promotes MoqSession
from a one-shot SETUP runner to a real concurrent session: the
control-stream and datagram pumps run on a caller-supplied scope
after the handshake, and a public subscribe()/unsubscribe() API
delivers per-track OBJECT_DATAGRAMs as a Flow<MoqObject>.
commonMain (nestsclient.moq):
- MoqSession now takes a `pumpScope: CoroutineScope` so callers can
bind the pumps to their lifecycle (test backgroundScope, viewmodel
scope, etc.).
- After setup() succeeds, two background coroutines start:
* Control-stream pump — buffers chunks across multiple writes,
decodes complete frames, dispatches SUBSCRIBE_OK / SUBSCRIBE_ERROR
to the matching CompletableDeferred, drops malformed frames
without killing the session.
* Datagram pump — decodes OBJECT_DATAGRAMs and routes each to the
matching per-track sink keyed by track_alias.
- `subscribe(namespace, trackName, priority, filter)` sends SUBSCRIBE,
awaits SUBSCRIBE_OK (throws MoqProtocolException on SUBSCRIBE_ERROR
with the publisher's reason), and returns a SubscribeHandle whose
`objects` flow emits inbound OBJECT_DATAGRAMs.
- `unsubscribe(subscribeId)` is idempotent; second call is a no-op.
close() cancels pumps + tears down all in-flight subscribes cleanly.
- Per-track sink uses a bounded Channel with DROP_OLDEST overflow
rather than MutableSharedFlow, so objects buffered between
subscribe() returning and the consumer attaching are preserved
(SharedFlow with replay=0 silently drops pre-subscription emissions).
transport (FakeWebTransport):
- Switched from `consumeAsFlow()` to `receiveAsFlow()` so a `.first()`
during setup followed by a long-running pump `.collect{}` works on
the same channel without the first call closing it.
Tests:
- Updated existing setup tests for the new `pumpScope` parameter.
- New `subscribe_completes_on_subscribe_ok_then_delivers_datagrams_in_order`
end-to-end: client subscribes, raw server peer (no MoqSession to
avoid pump-vs-test contention) replies SUBSCRIBE_OK + 3 datagrams,
client's flow yields all three in order with correct payloads.
- `subscribe_throws_MoqProtocolException_when_publisher_replies_with_subscribe_error`.
- `datagrams_for_unknown_track_alias_are_dropped_silently` ensures
the pump doesn't crash on orphan datagrams and the session stays
closeable.
This completes the pure-Kotlin MoQ work. Remaining 3.x phases all
touch real audio (MediaCodec Opus, AudioTrack, AudioRecord) or the
real WebTransport handshake (Phase 3b-2 with Kwik).

feat(nestsClient): MoQ SUBSCRIBE family + OBJECT_DATAGRAM codecs
Phase 3c-2 of the Clubhouse/nests integration. Extends the MoQ
control-plane codec with the subscribe lifecycle messages (SUBSCRIBE,
SUBSCRIBE_OK, SUBSCRIBE_ERROR, UNSUBSCRIBE) and adds the
OBJECT_DATAGRAM wire format the listener uses to receive low-latency
Opus audio. Pure codec layer — no session-pump or network changes;
the subscribe/object delivery Flow arrives in Phase 3c-3.
commonMain (nestsclient.moq):
- New message types in `MoqMessageType`: Subscribe (0x03),
SubscribeOk (0x04), SubscribeError (0x05), Unsubscribe (0x0A).
- New data classes in MoqMessage.kt:
* `TrackNamespace` — tuple of byte strings, with `of(vararg String)`
helper for the common UTF-8 case.
* `SubscribeFilter` enum. Phase 3c-2 supports LatestGroup /
LatestObject; AbsoluteStart/AbsoluteRange throw at construction
(they need extra wire fields we'll add when nests needs them).
* `Subscribe`, `SubscribeOk`, `SubscribeError`, `Unsubscribe` data
classes. `SubscribeOk` validates contentExists + largest-id
coupling at construction.
- New codecs in `MoqCodec` (namespace tuple + all four messages).
Unknown filter codes on the wire are rejected.
- `MoqObject` data class + `MoqObjectDatagram` encode/decode for the
OBJECT_DATAGRAM wire format (track_alias, group_id, object_id,
publisher_priority, status, payload).
Tests:
- `SubscribeCodecTest` — round-trips for each message with multi-
segment namespaces + parameters, SUBSCRIBE_OK with and without
contentExists, concatenated decode in sequence, unknown-filter
rejection, construction-time validation.
- `MoqObjectDatagramTest` — Opus-sized payload round-trip, zero-
length payload with OBJECT_DOES_NOT_EXIST status, 8-byte-varint
boundary coverage, truncated datagram rejection, out-of-range
priority rejection.

feat(nestsClient): MoQ varint + SETUP handshake codec
Phase 3c-1 of the Clubhouse/nests integration. Lands a MoQ-transport control-plane codec (draft-ietf-moq-transport) and a session wrapper that runs the SETUP handshake over any WebTransportSession. Purely commonMain + fully tested end-to-end against FakeWebTransport — no network or Kwik dependency required. commonMain (nestsclient.moq): - `Varint` — QUIC variable-length integer codec per RFC 9000 §16. Encode/decode/size, with typed truncation handling (decode returns null so callers can buffer more and retry). - `MoqWriter` / `MoqReader` — append-only byte writer + bounds-checked reader used by the message codec. - `MoqCodecException` — typed error for malformed frames. - `MoqMessage` sealed class + `MoqMessageType` enum + `SetupParameter`. Phase 3c-1 covers just `ClientSetup` / `ServerSetup` (message types 0x40 / 0x41). - `MoqCodec.encode/decode` — wraps payload with `type (varint) + length (varint)`. Rejects unknown types and trailing bytes inside a declared payload window. - `MoqSession.client/server` — attaches to a WebTransportSession and runs the CLIENT_SETUP / SERVER_SETUP handshake with version negotiation + configurable timeout. - `MoqVersion` constants for draft-11 and draft-17. Tests: - `VarintTest` — all four RFC 9000 §A.1 sample vectors (1/2/4/8 byte), boundary round-trips, negative/overflow rejection, short-buffer returns null, bytesConsumed accuracy. - `MoqCodecTest` — CLIENT_SETUP / SERVER_SETUP round-trip (empty and multi-param), multi-version negotiation, exact wire layout for ServerSetup(1L), truncated-frame returns null, concatenated frames decode with offset, unknown type rejected, trailing bytes rejected, zero-length parameter values allowed. - `MoqSessionTest` — full SETUP exchange over FakeWebTransport (both sides happy path, client falling back to older version, server rejecting when no version overlap + client timing out cleanly). SUBSCRIBE / ANNOUNCE / OBJECT_STREAM / OBJECT_DATAGRAM land in Phase 3c-2 on top of the same MoqSession. https://claude.ai/code/session_013nVLALALKaHVgHm9u5Cg8D |

feat(nestsClient): WebTransport abstraction + fake + Kwik stub
Phase 3b-1 of the Clubhouse/nests integration. Lands the [WebTransportSession] abstraction the MoQ layer (Phase 3c) will code against, so MoQ framing + tests can develop in parallel with the real Kwik-based transport integration (deferred to Phase 3b-2). commonMain: - `WebTransportSession` — bidi/uni stream access, datagrams, close. - `WebTransportBidiStream` / `WebTransportReadStream` / `WebTransportWriteStream` — minimal read/write surface. - `WebTransportFactory.connect(authority, path, bearerToken)` for opening sessions. - `WebTransportException(kind, ...)` with four canonical failure modes (HandshakeFailed, ConnectRejected, PeerClosed, NotImplemented) so UI code doesn't need to know about library-specific exceptions. - `FakeWebTransport.pair()` — in-memory, fully-wired client/server pair for unit-testing MoQ framing without touching a real QUIC stack. jvmAndroid: - `KwikWebTransportFactory` stub that throws `WebTransportException(NotImplemented)` at `connect()`. Doc spells out the handshake sequence (QUIC dial → H3 SETTINGS → `:method=CONNECT :protocol=webtransport` Extended CONNECT → 2xx) so Phase 3b-2 can drop the real implementation in without touching callers. Tests: - `FakeWebTransportTest` — datagram round-trip both directions, bidi-stream write visible on peer side, close() flips isOpen. - `WebTransportExceptionTest` — kind + message + cause preserved. - `KwikWebTransportFactoryTest` — `connect()` currently fails with the NotImplemented sentinel, so Phase 3b-2 can replace this test when the real handshake lands. https://claude.ai/code/session_013nVLALALKaHVgHm9u5Cg8D |

feat(nestsClient): NIP-98 auth + nests room-info client
Phase 3a of the Clubhouse/nests integration. Adds a new KMP module `nestsClient` (Android + JVM targets) that owns the HTTP control plane for talking to a nests audio-room backend. No transport/audio yet — that arrives in 3b with WebTransport + MoQ. Surface: - `NestsAuth.header(signer, url, method)` signs a kind 27235 event via Quartz's existing HTTPAuthorizationEvent and returns a ready-to-use `Authorization: Nostr <base64>` header value. - `NestsRoomInfo` data class + tolerant JSON parser (ignores unknown fields so newer nests server revisions don't break older clients). - `NestsClient.resolveRoom(serviceBase, roomId, signer)` calls `<serviceBase>/<roomId>` with the signed NIP-98 header and returns the MoQ endpoint + token the audio layer will need. - `OkHttpNestsClient` (jvmAndroid) is the default implementation shared between Android and desktop JVM. Tests: - `NestsRoomInfoTest` (commonTest) covers full/minimal payloads, unknown-field tolerance, missing-endpoint rejection, and URL construction edge cases. - `NestsAuthTest` (jvmTest) signs a real 27235 event, decodes the base64 back through Quartz's JacksonMapper, and asserts the signature verifies and the url+method tags bind correctly. https://claude.ai/code/session_013nVLALALKaHVgHm9u5Cg8D |
