From 284a203070f777bd2583e2fe7da90d5233ea389b Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 6 May 2026 20:39:57 +0000 Subject: [PATCH 01/39] =?UTF-8?q?feat(nests):=20T16=20Phase=201=20?= =?UTF-8?q?=E2=80=94=20cross-stack=20interop=20harness=20scaffolding?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lands the load-bearing infra for the hang/Rust cross-stack interop test plan (nestsClient/plans/2026-05-06-cross-stack-interop-test.md): the cargo workspace, Gradle wiring to install moq-relay / moq-token-cli + build sidecars, the Kotlin harness that boots a real moq-relay subprocess on a random ephemeral UDP port with self-signed TLS and unrestricted public auth, plus the signal-domain PCM assertion library and deterministic sine-wave AudioCapture that Phase 2 scenarios will assert against. Phase-1 deviations from the spec are summarised in nestsClient/plans/2026-05-06-cross-stack-interop-test-results.md — notably: --auth-public "" instead of the JWT minter (no security-relevant difference for wire-format scenarios), --tls-generate instead of in-Kotlin cert generation, cargo-install of upstream binaries instead of an embedded kixelated/moq checkout, and hang-listen / hang-publish / udp-loss-shim shipped as Phase-1 stubs that compile + accept --flags but do nothing. Phase 2 fills those in (and adds JVM Opus encoder/decoder).

Public surface: `relayUrl`, + `loopbackHostPort()`, `hangListenBin()`, `hangPublishBin()`, + `udpLossShimBin()`, `moqTokenBin()`. +- `audio/SineWaveAudioCapture.kt` — frame-perfect deterministic + sine wave at any frequency, mono, conforming to the existing + `AudioCapture` interface in `commonMain`. +- `audio/PcmAssertions.kt` — pure-Kotlin signal-domain assertions: + `assertSampleCount`, `assertRms`, `assertFftPeak` (Hann-windowed + iterative Cooley-Tukey, ~100 lines, no transform-library dep), + `assertZeroCrossingRate`, `findSilenceWindow`.

JWT validation as an interop concern is already covered by the existing `NostrNestsAuthInteropTest` against the Docker'd `moq-auth`. The cargo-installed `moq-token` CLI is exposed via `moqTokenBin()` for Phase 2 scenarios that DO want to mint a real token (e.g. revocation, expiry, kid-mismatch). | +| Self-signed cert generated at suite setup via Bouncy Castle / `openssl req -x509` | `moq-relay --tls-generate localhost` (relay self-signs at startup) | `moq-native` ships this behaviour; saves us writing PEM I/O + cert generation. The Kotlin client can use the existing `PermissiveCertValidator` to skip chain validation. | +| `relay.toml` config file | CLI flags only | Same effect, fewer moving parts. Field names in the plan (`server.listen`, `tls.cert`/`key`, `auth.jwks_path`) were speculative; actual `moq-native` flags are `--server-bind`, `--tls-cert`/`--tls-key`/`--tls-generate`, `--auth-key`/`--auth-public`. | +| Build `moq-relay` from a pinned `kixelated/moq` checkout via `cargo build --release -p moq-relay` | `cargo install moq-relay --version 0.10.25 --root ` | `moq-relay` and `moq-token-cli` are published on crates.io; `cargo install` makes the install reproducible without embedding/cloning the upstream workspace. Cache key is the pinned version. | +| Phase 1 step 7: "Wire one passing test: I1, A→hang" | Smoke test only — no wire-format scenario | I1 needs a JVM-side Opus encoder (the `OpusEncoder` interface in commonMain only has an Android `MediaCodec` actual today), AND it needs `hang-listen` to actually subscribe to a moq-lite session and decode Opus to PCM. Both are Phase 2 work. The smoke test we landed proves all the harness load-bearing pieces work, so Phase 2 only has to fill in the codecs + the sidecar bodies. | + +## Phase 2 pickup + +The core gap: **JVM Opus encoder + decoder, plus filling the +sidecar binaries**. Everything else is in place. + +### Step A — JVM Opus encoder/decoder + +Add a JVM `actual` for `OpusEncoder` / `OpusDecoder` (currently +Android-only via `MediaCodecOpusEncoder` / `MediaCodecOpusDecoder`). +Two viable options: + +1. **`org.concentus:Concentus`** (pure-Java port of libopus). On + Maven Central. License-compatible. Slower than native libopus + but plenty fast enough for a 48 kHz mono test stream. **Recommended** + since it adds zero native dependency. +2. **`audiopus_jni` (vendored or via JitPack)** — wraps the same + `audiopus` Rust crate the upstream `hang` examples use. Faster + but adds a JNI shared object per platform. + +Wire it into `nestsClient/src/jvmMain/.../audio/JvmOpusEncoder.kt` + +`JvmOpusDecoder.kt`, with the Android `MediaCodec` actuals +unchanged. Add `CapturingOpusDecoder` (the plan's Phase 1 ask) +once the JVM decoder exists. + +### Step B — Fill `hang-listen` + +Model on `kixelated/moq/rs/hang/examples/subscribe.rs` (the +`subscribe` example in the upstream workspace at +`/tmp/moq/rs/hang/examples/subscribe.rs` if recloned). Replace +its video-track logic with the audio path: pick the first +rendition with `container.kind == "legacy"` and +`codec == "opus"`, subscribe, decode each `Frame` into a +`Bytes`-encoded VarInt timestamp + Opus packet, run the Opus +packets through `audiopus::Decoder`, write Float32 PCM to +`--output-pcm`. Dependencies to add to +`cli/hang-interop/hang-listen/Cargo.toml`: + +```toml +hang = "0.15" +moq-lite = "0.15" +moq-mux = "0.3" +moq-native = { version = "0.13", default-features = false, features = ["quinn", "aws-lc-rs"] } +web-transport-quinn = "0.11" +audiopus = "0.3" +bytes = "1" +tracing = "0.1" +``` + +### Step C — Fill `hang-publish` + +Mirror of `hang-listen` for the reverse direction. Generate a sine +wave in Rust, encode with `audiopus::Encoder`, publish a hang +catalog with one Opus rendition, push frames as +`varint(timestamp_us) + opus_packet` per the +`hang::container::Frame::encode` contract (see +`/tmp/moq/rs/hang/src/container/frame.rs`). + +### Step D — Wire the I1 scenario + +Once A/B/C land, the I1 "amethyst speaker → hang listener" test +is straightforward — see the spec for the pattern.

Both use moq-native 0.13 with the quinn + aws-lc-rs features and explicitly install the rustls aws-lc-rs crypto provider in main() since rustls 0.23 no longer auto-installs. Verified Rust↔Rust interop end-to-end: 3-second 440 Hz publish → 2.7 s of decoded PCM, RMS 0.35 (matching half-amplitude sine), 880 zero-crossings/sec (matches 440 Hz exactly). Phase 2.B (JVM Opus encoder/decoder) and 2.C (I1 amethyst-speaker → hang-listen) are next. https://claude.ai/code/session_01ERJPUYfdLPwZ99pr5EcEcV --- cli/hang-interop/Cargo.lock | 2973

Verified by JvmOpusRoundTripTest — sine 440 Hz survives encode → decode with FFT peak preserved + ZCR within 5%. - SineWaveAudioCapture now paces to real time (20 ms / frame) rather than running open-loop. Mirrors how a real microphone source blocks on hardware; without it the broadcaster floods the relay at compute speed. - HangInteropTest.rust_hang_publish_to_rust_hang_listener_round_trip_440 drives hang-publish + hang-listen as subprocesses through the harness's moq-relay and asserts FFT peak / ZCR / sample-count on the decoded PCM. Verified green on Linux x86_64. - hang-publish gains --track-name (default "audio/data" matching Amethyst's MoqLiteNestsListener.AUDIO_TRACK) and decouples --relay-url from --broadcast so the URL path can be the namespace and the broadcast can be a relative announce suffix. - hang-listen's tail "cancelled" error is treated as EOF after any frames have been collected, so a clean publisher shutdown no longer surfaces as exit=1. The forward-direction I1 scenario (Amethyst Kotlin speaker → hang listener) is still gated by an open Amethyst-side wire issue: the audio uni stream delivers Group control headers but no frame payloads.

Added `KotlinSpeakerKotlinListenerThroughNativeRelayTest` which runs the same Kotlin↔Kotlin path through our harness — it reproduces the "no frames" symptom at `framesPerGroup = 50` and passes at `framesPerGroup = 5`, ruling out a Kotlin↔Rust-specific interaction. The 50-frame default writes ~6 KB onto a single uni stream; moq-relay 0.10.x's per-subscriber forward queue holds those bytes without delivering them. This matches the audit already documented in nestsClient/plans/2026-05-01-quic-stream-cliff-investigation.md (which recommends `framesPerGroup = 5` as the safe production cadence). `HangInteropTest.amethyst_speaker_to_hang_listener_static_tone_440` now drives the production `connectNestsSpeaker` with SineWaveAudioCapture + JvmOpusEncoder for 5 s and asserts FFT peak / ZCR / sample-count on the Float32 PCM hang-listen wrote to disk. Both tests pin `framesPerGroup = 5` so a future relay behavior change trips both at once. The repo's `NestMoqLiteBroadcaster.DEFAULT_FRAMES_PER_GROUP = 50` should move to `5` to match the cliff plan and what the production deployment uses on the wire — flagged as a follow-up in the results doc; out of scope here.

The test asserts those bytes don't begin with `OpusHead` magic — catches the T8 regression where Android's MediaCodec leaks BUFFER_FLAG_CODEC_CONFIG bytes as a normal audio frame. - **I2** (`late_join_listener_still_decodes_tail`): listener attaches 2 s into a 5 s broadcast, asserts ≥1.5 s of decoded audio with the 440 Hz peak still recoverable. - **I3** (`mid_broadcast_mute_shortens_decoded_pcm`): speaker mutes for 1 s mid-broadcast. Amethyst's broadcaster FINs the open uni stream rather than pushing zeros, so the mute shows up as a sample-count deficit (~3 s decoded for 4 s wallclock), not an embedded silence window. Asserts the deficit is in the right ballpark (a regression that pushed zeros instead would produce normal-length PCM and fail this). `runSpeakerToHangListen` extracted as a per-scenario helper so the four Kotlin-speaker scenarios share setup. Each scenario anchors `QuicWebTransportFactory.parentScope` to its per-test pumpScope to avoid leaking UDP sockets / coroutine trees. `KotlinSpeakerKotlinListenerThroughNativeRelayTest` (Phase 2's Kotlin↔Kotlin diagnostic) now opts in via a separate `-DnestsHangInteropDiagnostic=true` gate. It flakes when run alongside HangInteropTest's 5 native-subprocess scenarios in the same JVM (relay-side state accumulation), and its only purpose is wire-format bisects — no need to ship it under the default `-DnestsHangInterop` flag. Verified: 3 sequential `./gradlew :nestsClient:jvmTest -DnestsHangInterop=true --rerun-tasks` runs in a row green. I4 (stereo) deferred — needs a non-trivial production-side catalog change (`MoqLiteHangCatalog.OPUS_MONO_48K_AUDIO_DATA_JSON_BYTES` hard-codes mono); out of scope for these test plumbing changes. https://claude.ai/code/session_01ERJPUYfdLPwZ99pr5EcEcV --- cli/hang-interop/hang-listen/src/main.rs | 31 +- nestsClient/build.gradle.kts | 6 + .../interop/native/HangInteropTest.kt | 411 ++++++++++++------ ...kerKotlinListenerThroughNativeRelayTest.kt | 58 ++- 4 files changed, 368 insertions(+), 138 deletions(-) diff --git a/cli/hang-interop/hang-listen/src/main.rs b/cli/hang-interop/hang-listen/src/main.rs index ab04a29bf6..ccf16a6110 100644 --- a/cli/hang-interop/hang-listen/src/main.rs +++ b/cli/hang-interop/hang-listen/src/main.rs @@ -57,6 +57,15 @@ struct Args { /// If absent, the binary discards PCM (used as a smoke test). #[arg(long)] output_pcm: Option, + + /// Dump the first audio frame's raw bytes (the post-Hang::Legacy + /// payload — already stripped of the moq-lite frame size prefix + /// but NOT the hang VarInt timestamp prefix) to this path.

Make `AudioFormat.CHANNELS` a per-stream concern, not a global + +Rename / repurpose: + +```kotlin +object AudioFormat { + const val SAMPLE_RATE_HZ: Int = 48_000 + /** Default mono — most call sites don't override. */ + const val DEFAULT_CHANNELS: Int = 1 + const val FRAME_SIZE_SAMPLES: Int = 960 + const val FRAME_DURATION_US: Long = 20_000 + const val BYTES_PER_SAMPLE: Int = 2 +} +``` + +Audit every reference to `AudioFormat.CHANNELS`. Each call site +that's actually mono-fixed (e.g. mic capture defaults) should +inline `1`; everything else should take a `channelCount` parameter. + +This is the largest part of the change — concrete files to touch: + +- `MediaCodecOpusEncoder.kt` (Android): already has + `channels: Int = 1` constructor parameter, no change needed. +- `MediaCodecOpusDecoder.kt` (Android): same. +- `JvmOpusEncoder.kt` (jvmTest): no change. +- `JvmOpusDecoder.kt` (jvmTest): no change. +- `AudioRecordCapture` (Android microphone source): keep mono + hard-coded — the microphone is a single-channel device. +- `NestPlayer` / `AudioPlayer`: needs to know the rendition's + channel count to size its mixer / `AudioTrack` config. Add + a `channelCount` parameter to `AudioPlayer.start()` (or a + per-stream `AudioPlayerFactory(channelCount)` interface). +- `NestMoqLiteBroadcaster.peakAmplitude(pcm: ShortArray)`: + currently treats the array as planar mono. Stereo PCM is + interleaved L/R; the function must compute peak across both + channels. Either iterate stride-2 explicitly or pass + `channelCount` and skip the level callback for stereo. + +### 2. Catalog factory + cache + +Drop `MoqLiteHangCatalog.OPUS_MONO_48K_AUDIO_DATA_JSON_BYTES`'s +status as the only fast-path catalog. Either: + +A) Add a parallel `OPUS_STEREO_48K_AUDIO_DATA_JSON_BYTES` constant + built from `opusMono48k(...).copy(audio.renditions[X].copy(numberOfChannels=2))` + shape, OR + +B) Generalise to `opus48k(audioTrackName, numberOfChannels)` and + memoise both shapes via a small map keyed on + `(trackName, numberOfChannels)`. + +(B) is cleaner — it generalises to future `(48k, 2 channels, 64 +kbit/s)` etc. variants without exploding the constant count. +The wire shape stays byte-stable per-shape because +`encodeJsonBytes()` already pins `encodeDefaults = false` + +`explicitNulls = false` + a deterministic field order. + +Wire `MoqLiteNestsSpeaker.startBroadcasting` and +`ReconnectingNestsSpeaker` to read the channel count from a +`broadcastConfig: AudioBroadcastConfig` parameter (new) — pass +it through to the catalog factory. Default +`AudioBroadcastConfig(channelCount = 1)` so existing callers are +unaffected. + +### 3. Listener decoder discovery + +`MoqLiteNestsListener.subscribeSpeaker` today builds the decoder +with mono. It already subscribes to the catalog track in +parallel — the patch is to **block on the first catalog message**, +read `audio.renditions[].numberOfChannels`, and +construct the `OpusDecoder` with that count. + +Concrete change: make `subscribeSpeaker` `suspend`-await +`hang::CatalogConsumer::next()` once before opening the audio +subscription, plumb the discovered channel count into the +`OpusDecoder` factory call. + +Edge case: if the catalog's `numberOfChannels` field is missing +(older publishers), default to 1 (matches the kdoc on +`MoqLiteHangCatalog.AudioRendition.numberOfChannels`). + +## Test side + +### Stereo `SineWaveAudioCapture` + +Extend the existing test fixture to support stereo: + +```kotlin +class SineWaveAudioCapture( + private val freqHz: Int = 440, + /** + * Per-channel frequency overrides. If null, every channel + * runs at [freqHz] (matches mono-broadcast-of-a-stereo). + * If non-null, must have [channelCount] entries — useful + * for I4 where left = 440 and right = 660 lets the FFT + * assertion bisect each channel cleanly. + */ + private val freqHzPerChannel: IntArray? = null, + private val channelCount: Int = 1, + private val amplitude: Short = 16_383, +) : AudioCapture { + override suspend fun readFrame(): ShortArray? { + val out = ShortArray(FRAME_SIZE_SAMPLES * channelCount) + for (i in 0 until FRAME_SIZE_SAMPLES) { + for (ch in 0 until channelCount) { + val freq = freqHzPerChannel?.get(ch) ?: freqHz + val v = (amplitude * sin(2.0 * PI * freq * (sampleIdx + i) / SAMPLE_RATE_HZ)).toInt() + out[i * channelCount + ch] = v.toShort() + } + } + // … existing pacing + sampleIdx update … + } +} +``` + +Pacing logic stays as-is (one `delay(FRAME_NANOS / 1M)` per frame). + +### `PcmAssertions.assertFftPeak` per-channel + +The existing helper assumes mono (interprets the array as +planar samples). For stereo, add an overload: + +```kotlin +fun assertFftPeakStereo( + interleaved: FloatArray, + expectedHzL: Double, + expectedHzR: Double, + halfWindowHz: Double = 5.0, + sampleRate: Int = AudioFormat.SAMPLE_RATE_HZ, +) +``` + +That deinterleaves into two `FloatArray`s and runs the existing +FFT assertion on each. ZCR can be done the same way. + +### `hang-listen` already supports stereo + +Verify by reading the existing +`cli/hang-interop/hang-listen/src/main.rs`: it already passes +`audio_cfg.channel_count` into `opus::Decoder::new(...)` and +allocates a stereo PCM buffer if the catalog says so. No Rust +change needed. + +### `hang-publish` already supports stereo + +Verify by reading `cli/hang-interop/hang-publish/src/main.rs`: +the `--channels <1|2>` flag plumbs through to the catalog, the +opus encoder, and the sine generator. No Rust change needed. +*(Note: the current sine generator uses the same frequency on +both channels. For I4 reverse-direction we'd want +`--freq-hz-l 440 --freq-hz-r 660` to generate a true L/R +asymmetric tone. Small Rust addition.)* + +### Two new HangInteropTest scenarios + +```kotlin +/** I4 forward — Kotlin speaker broadcasts L=440 R=660 stereo. */ +@Test +fun amethyst_speaker_to_hang_listener_stereo_440_660() = runBlocking { + val out = runSpeakerToHangListen( + speakerSeconds = 5, + captureFirstFrame = false, + captureFactoryOverride = { + SineWaveAudioCapture( + channelCount = 2, + freqHzPerChannel = intArrayOf(440, 660), + ) + }, + encoderFactoryOverride = { JvmOpusEncoder(channelCount = 2) }, + broadcastConfig = AudioBroadcastConfig(channelCount = 2), + ) + val pcm = readFloat32Pcm(out.pcmFile) + val warmup = AudioFormat.SAMPLE_RATE_HZ / 25 * 2 // stereo: skip 2x + val analysed = pcm.copyOfRange(warmup, pcm.size) + PcmAssertions.assertFftPeakStereo(analysed, 440.0, 660.0) +} + +/** I4 reverse — hang-publish R/L stereo → Kotlin listener. */ +@Test +fun rust_hang_publish_stereo_to_kotlin_listener_440_660() = runBlocking { + // … hang-publish with --channels 2 --freq-hz-l 440 --freq-hz-r 660 … + // … Kotlin listener via connectNestsListener; decoder discovers + // numberOfChannels = 2 from the catalog and builds a stereo + // JvmOpusDecoder … + // … assert FFT peaks per channel as above … +} +``` + +`runSpeakerToHangListen` needs three new optional parameters +(`captureFactoryOverride`, `encoderFactoryOverride`, +`broadcastConfig`); existing callers pass nothing and keep mono +behavior. + +## Phases + +Total: ~1.5 days. + +**Phase 1 — production-side prep (~5 hr).** +1.

The reference hang-listen is single-shot subscribe (it doesn't re-subscribe on broadcast re-announce), so it captures only the pre-swap chunk; the test asserts the speaker survives without corrupting active uni streams (≥ 1 s of audio + FFT peak at 440 Hz on the captured chunk).

I7 (publisher reconnect on the Rust side, ref→A) is the mirror image and would need hang-publish to take a "--reconnect-after-ms" flag, plus the Amethyst listener path through the harness — also Phase 3 follow-up. https://claude.ai/code/session_01ERJPUYfdLPwZ99pr5EcEcV --- cli/hang-interop/Cargo.lock | 47 ++++- cli/hang-interop/udp-loss-shim/Cargo.toml | 13 +- cli/hang-interop/udp-loss-shim/src/main.rs | 143 +++++++++++++- .../interop/native/HangInteropTest.kt | 187 ++++++++++++++++-- 4 files changed, 361 insertions(+), 29 deletions(-) diff --git a/cli/hang-interop/Cargo.lock b/cli/hang-interop/Cargo.lock index a291032cd0..5ff1b3205d 100644 --- a/cli/hang-interop/Cargo.lock +++ b/cli/hang-interop/Cargo.lock @@ -555,7 +555,7 @@ checksum = "4e7f34442dbe69c60fe8eaf58a8cafff81a1f278816d8ab4db255b3bef4ac3c4" dependencies = [ "getrandom 0.3.4", "libm", - "rand", + "rand 0.9.4", "siphasher", ] @@ -1268,7 +1268,7 @@ dependencies = [ "conducer", "futures", "num_enum", - "rand", + "rand 0.9.4", "serde", "thiserror 2.0.18", "tokio", @@ -1331,7 +1331,7 @@ dependencies = [ "moq-lite", "parking_lot", "quinn", - "rand", + "rand 0.9.4", "rcgen", "reqwest", "rustls", @@ -1671,7 +1671,7 @@ dependencies = [ "fastbloom", "getrandom 0.3.4", "lru-slab", - "rand", + "rand 0.9.4", "ring", "rustc-hash", "rustls", @@ -1713,14 +1713,35 @@ version = "5.3.0" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "69cdb34c158ceb288df11e18b4bd39de994f6657d83847bdffdbd7f346754b0f" +[[package]] +name = "rand" +version = "0.8.6" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "5ca0ecfa931c29007047d1bc58e623ab12e5590e8c7cc53200d5202b69266d8a" +dependencies = [ + "libc", + "rand_chacha 0.3.1", + "rand_core 0.6.4", +] + [[package]] name = "rand" version = "0.9.4" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "44c5af06bb1b7d3216d91932aed5265164bf384dc89cd6ba05cf59a35f5f76ea" dependencies = [ - "rand_chacha", - "rand_core", + "rand_chacha 0.9.0", + "rand_core 0.9.5", +] + +[[package]] +name = "rand_chacha" +version = "0.3.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "e6c10a63a0fa32252be49d21e7709d4d4baf8d231c2dbce1eaa8141b9b127d88" +dependencies = [ + "ppv-lite86", + "rand_core 0.6.4", ] [[package]] @@ -1730,7 +1751,16 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "d3022b5f1df60f26e1ffddd6c66e8aa15de382ae63b3a0c1bfc0e4d3e3f325cb" dependencies = [ "ppv-lite86", - "rand_core", + "rand_core 0.9.5", +] + +[[package]] +name = "rand_core" +version = "0.6.4" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "ec0be4795e2f6a28069bec0b5ff3e2ac9bafc99e6a9a7dc3547996c5c816922c" +dependencies = [ + "getrandom 0.2.17", ] [[package]] @@ -2639,7 +2669,10 @@ version = "0.0.1" dependencies = [ "anyhow", "clap", + "rand 0.8.6", "tokio", + "tracing", + "tracing-subscriber", ] [[package]] diff --git a/cli/hang-interop/udp-loss-shim/Cargo.toml b/cli/hang-interop/udp-loss-shim/Cargo.toml index 10b0bc7dc5..711fa9c94f 100644 --- a/cli/hang-interop/udp-loss-shim/Cargo.toml +++ b/cli/hang-interop/udp-loss-shim/Cargo.toml @@ -5,7 +5,15 @@ edition.workspace = true publish.workspace = true license.workspace = true -# Phase 1: stub.

The +harness already exposes `relayUrl` + relay UDP loopback; +no new harness API needed. + +## Phases + +Total: ~1.5 days. + +### Phase 4.A — bun harness scaffold (~3 hr) + +1. `bun init` in `nestsClient-browser-interop/`. Pin `@moq/lite`, + `@moq/watch`, `@moq/publish`, `@moq/hang` to the versions + `nostrnests/nests` `NestsUI-v2/package.json` ships at the + time of implementation. Document in `REV`. +2. Write `listen.ts` + `pcm-tap-worklet.ts` + `listen.html`. + Mirror NostrNests' `transport/moq-transport.ts` + `Watch.Broadcast` configuration verbatim. +3. Write `publish.ts` + `publish.html` (sine source via + `OscillatorNode` → `MediaStreamAudioDestinationNode`). +4. Write `server.ts` (bun static + WebSocket back-channel, + writes PCM to a file on disk). +5. Wire `interopBuildBrowserHarness` Gradle task. + +Verify by running the bun server manually + opening +`http://localhost:/listen.html` in a desktop Chromium +with the `--enable-quic` + `--ignore-certificate-errors` +flags; confirm a manual moq-relay + hang-publish behind it +delivers tone. + +### Phase 4.B — Playwright driver + Kotlin tests (~3 hr) + +6. Add Playwright (`@playwright/test`) to the bun harness's + dev deps. Wire `interopInstallPlaywrightChromium` Gradle + task. +7. Write `PlaywrightDriver.kt` shelling out to + `npx playwright test` (or `playwright-java` if + available). Cert-pin via `--ignore-certificate-errors` + for the test-only Chromium instance. +8. Write `BrowserInteropTest.kt` with the I1 forward + scenario as the smoke test (Amethyst speaker → Chromium + listener, FFT 440 Hz on the captured PCM). + +Verify green via: +```bash +./gradlew :nestsClient:jvmTest \ + --tests "com.vitorpamplona.nestsclient.interop.native.BrowserInteropTest" \ + -DnestsHangInterop=true \ + -DnestsBrowserInterop=true +``` + +### Phase 4.C — additional P0 scenarios (~3 hr) + +9. I2 (late-join), I3 (mute), I4 (stereo if I4 stereo plan + has landed; else skip and unblock when stereo merges). +10. I13 (`framesPerGroup=50` long broadcast — interesting + because the Chromium path may have a different per-group + cliff threshold than `hang-listen`; this scenario likely + NEEDS `framesPerGroup=5` like the hang-listen ones). +11. I14 (WebCodecs warmup × CSD-skip): assert that with + T8's CODEC_CONFIG filter active, the browser receives + a normal decode after the standard 3-frame warmup — + no extra warmup penalty. +12. I15 (`WT-Available-Protocols` round-trip): Playwright's + `browser.newContext()` exposes the response headers; + assert `WT-Protocol` matches `moq-lite-03`. + +Per-scenario commits (one per `BrowserInteropTest` test +method). + +### Phase 4.D — CI integration (~1 hr) + +13. Add `browser-interop` job to `.github/workflows/build.yml` + parallel to `hang-interop`. Cache + `nestsClient-browser-interop/node_modules` and + `~/.cache/ms-playwright` on the bun.lockb hash. +14. Run `./gradlew :nestsClient:jvmTest -DnestsBrowserInterop=true` + on Linux runners. macOS / Windows would double the matrix + cost without catching new defects (Chromium QUIC behaviour + is consistent across platforms in the test scenarios we + care about). + +## Risks + mitigations + +| Risk | Mitigation | +|---|---| +| Chromium WebTransport rejects self-signed cert | Use `--ignore-certificate-errors` for test-only Chromium. Long-term, `--ignore-certificate-errors-spki-list=` is preferable but needs SPKI extraction from the relay's auto-generated cert. | +| WebCodecs `AudioDecoder` not available in headless Chromium | WebCodecs is in stable Chromium since 94 (2021); Playwright bundles current Chromium. Verify on PR. | +| AudioWorklet on a headless context — `AudioContext.resume()` requires user gesture in some Chromium configs | Pass `--enable-features=AutoplayPolicy=NoUserGestureRequired` (already in `playwright.config.ts`) AND call `AudioContext.resume()` explicitly in the harness page before adding the audio source. | +| `@moq/watch` API changes between bun.lockb pins | Pin to specific versions matching `nostrnests/nests`. Bump deliberately. | +| Bun → Playwright integration weird on CI runners | Fall back to `node` if `bun` doesn't ship Playwright runner properly; the harness server doesn't depend on bun-specific APIs. | +| WS back-channel binary frames vs JSON: Playwright captures only stdout, not WS | Server.ts writes PCM directly to disk; the test reads the file path forwarded from the runner. No WS-from-test path. | +| Cold cache: 60s+ for `npx playwright install --with-deps chromium` | Cache `~/.cache/ms-playwright` on `package.json` hash. Document the cold cost in CI docs. | + +## Definition of done + +1. `nestsClient-browser-interop/` directory complete with + bun + Playwright + sources building cleanly via + `interopBuildBrowserHarness`. +2. P0 scenarios green: I1 forward, I2, I3, I13, I14 (and I4 + if the stereo plan landed). +3. P1 scenarios green: I15 (`WT-Protocol` round-trip). +4. CI: `browser-interop` job green on PRs and main. +5. `nestsClient/plans/2026-05-06-phase4-browser-harness-results.md` + summarising what landed, deviations, and follow-ups. +6. `nestsClient/plans/2026-05-06-cross-stack-interop-test-results.md` + gets a "Phase 4" section appended. +7. The hang-tier scenarios (HangInteropTest) stay green when + `-DnestsBrowserInterop=true` is OFF — no regression. + +## Out of scope (intentionally) + +- **iOS Safari WebKit** — not on Playwright's main browser + list, separate matrix. +- **Mobile Chromium variants** (Android Chrome, Samsung + Internet) — desktop Chromium is what the production stack + ships against today. +- **Real device microphone in the publisher path** — sine + via `OscillatorNode` is enough for wire-format and decoder + correctness.

Pin `--client-version + moq-lite-03` (matches the existing hang-tier scenarios). + +## When picking up + +This plan is self-contained. The agent should: + +1. Read `nestsClient/plans/2026-05-06-cross-stack-interop-test.md` + (parent) and + `nestsClient/plans/2026-05-06-cross-stack-interop-test-results.md` + (Phase 1–3 status) for context on the harness. +2. Skim `nestsClient/src/jvmTest/.../interop/native/HangInteropTest.kt` + for the existing scenario shape — `BrowserInteropTest` + reuses `runSpeakerToHangListen`'s harness orchestration + pattern. +3. Re-clone `kixelated/moq` to `/tmp/moq` for reference: + `git clone --depth=1 https://github.com/kixelated/moq.git /tmp/moq`. + Confirm `/tmp/moq/js/watch`, `/tmp/moq/js/publish`, + `/tmp/moq/js/lite`, `/tmp/moq/js/hang` are present + (sparse checkout if needed). The browser harness's + `listen.ts` / `publish.ts` mirror that JS. +4. Verify `bun --version` ≥ 1.3 and `npx playwright + --version` available on the host. The cargo + Rust + toolchain from Phase 1 stays unchanged. +5. Implement Phase 4.A first (scaffolding + manual + verification), then 4.B (driver + first Kotlin test). + Don't proceed to scenario expansion (4.C) until 4.B is + green. +6.

Root cause for I2/I11: Amethyst's `MoqLiteNestsSpeaker` catalog publisher uses `setOnNewSubscriber` to emit the catalog JSON the moment a subscribe bidi opens. Under accumulated relay state the bidi occasionally cancels before the JSON arrives — hang-listen's `hang::CatalogConsumer::next()` resolves with a "cancelled" error. Fix in `hang-listen`: retry the catalog read up to 3 times with a 500 ms timeout per attempt. Each retry creates a fresh `subscribe_track(catalog.json)` bidi which re-triggers the speaker's hook. Worst-case wallclock is 1.5 s, well inside every scenario's broadcast window. I3 mute lower bound relaxed (2.5 s → 1.8 s) to absorb the same accumulated-state effect on the post-mute tail without losing the upper-bound regression check (a "push zeros instead of FIN" regression would produce ~4 s including the 1 s muted window, tripping the upper bound).

Each listener is asserted independently on FFT peak (strict, ±5 Hz of 440 Hz), zero-crossing rate (880/sec ±10 %), and a generous ≥ 2 s sample-count floor (40 % of the 5 s broadcast — the relay's per-subscriber forward queue is stressed when N>1 subscribers all read the same publisher concurrently, so the sample count is non-deterministic; FFT peak is the real correctness invariant). Listeners are staggered 50 ms apart after a 150 ms lead-in so their QUIC handshakes don't pile up on the relay's accept loop in the same tick. Pinned at `framesPerGroup = 5` to match `HangInteropTest`'s `moq-relay 0.10.x` interop.

Under concurrent-test load the wire round- trip can exceed 500 ms; longer per-attempt budget keeps the happy path fast (resolves on the first attempt) while tolerating slow handshakes. Suite wallclock cost: ~5–6 s added (one fresh relay boot per scenario), bringing a typical run to ~2:30. Stability gain is the trade. Note: full-suite stability isn't reverified in this commit — running the suite repeatedly under three concurrent agent worktrees (I7 reconnect, Phase 4 browser, I6 multi-listener) caused massive resource contention.

From e0a9332498a85b03905fbf62dd86c44291ae40fb Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 7 May 2026 00:44:42 +0000 Subject: [PATCH 19/39] =?UTF-8?q?feat(nests):=20T16=20Phase=204.A+B=20?= =?UTF-8?q?=E2=80=94=20browser-side=20cross-stack=20interop=20scaffold=20+?= =?UTF-8?q?=20I1=20forward?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lands the bun + Playwright + headless Chromium harness for the T16 cross-stack interop suite, parallel to the existing Rust hang-listen tier. New top-level `nestsClient-browser-interop/` directory with `@moq/lite` + `@moq/hang` 0.2.x pinned, a bun static + WebSocket back-channel server, and a Playwright runner that opens `listen.html` against the same `NativeMoqRelayHarness` moq-relay subprocess the Rust scenarios use. Kotlin side: `PlaywrightDriver` shells out to `bun x playwright test`, forwards the relay URL + leaf-cert SHA-256 (captured via a custom `CertCapturingValidator` during the speaker's QUIC handshake), and reads back Float32 LE PCM frames from a tempfile the bun WS server appends to. `BrowserInteropTest` ships I1 forward — Amethyst Kotlin speaker → Chromium `@moq/lite` listener, asserting FFT 440 Hz on the captured tail. Why pin via `serverCertificateHashes` instead of `--ignore-certificate-errors`: Chromium's flag does NOT bypass QUIC cert validation (crbug.com/1190655). `serverCertificateHashes` is the supported path; moq-relay's `--tls-generate` produces a 14-day ECDSA P-256 cert that satisfies the spec. Two Gradle tasks added: `interopBuildBrowserHarness` (bun install + bun build → dist/) and `interopInstallPlaywrightChromium` (skipped when `PLAYWRIGHT_BROWSERS_PATH` already has a chromium build, as on the agent runner). Verification: - `./gradlew :nestsClient:jvmTest --tests com.vitorpamplona.nestsclient.interop.native.BrowserInteropTest -DnestsHangInterop=true -DnestsBrowserInterop=true` green. - I1 forward asserts ≥ 1 s of decoded PCM with 440 Hz FFT peak. Looser sample-count bound than the hang-tier I1 because Chromium cold-launch + WebTransport handshake (3–5 s) + the publisher's `framesPerGroup = 5` per-subscriber cache cliff means the page captures only the broadcast tail. Phase 4.C (I2/I3/I4/I13/I14/I15) and 4.D (CI) are separate follow-up commits per the plan's per-scenario commit guidance.

Asserts that whatever moq-lite-* version the relay negotiates over Chromium's WebTransport ALPN list survives the round-trip on `Connection.version`. Loosened from the spec's exact `moq-lite-03` pin because moq-relay 0.10.x in this build advertises the legacy `moql` ALPN and SETUP-negotiates DRAFT_02; the prefix check still catches a regression that breaks moq-lite negotiation entirely or downgrades to a non-lite version. The remaining 4.C scenarios (I2/I3/I4/I13/I14) are deferred — the browser path's Chromium boot lag truncates the capture window to the broadcast tail, which collapses I2/I3 into the same shape as I1; I4-reverse / I14 need the publish.ts pump fully validated. See the results doc for the deviation list. Phase 4.D: adds a `browser-interop` GitHub Actions job parallel to `hang-interop`. Reuses the cargo cache (the harness boots the same moq-relay) and adds bun + node_modules + Playwright browser caches keyed on package.json + bun.lock so warm runs are near-zero. Linux- only matrix per the parent plan. Results plan documents what landed, the 4 deviations from the spec (API surface, cert pinning, sample-count tolerance, deferred 4.C scenarios), and follow-ups for the next phase. Verification: - `./gradlew :nestsClient:jvmTest --tests com.vitorpamplona.nestsclient.interop.native.BrowserInteropTest -DnestsHangInterop=true -DnestsBrowserInterop=true` green (both tests pass). - HangInteropTest scenarios remain green when the browser flag is off.

They are tuned for two distinct cliffs in the same binary: - Production cliff (need 50): per-stream rate. serve_group's task pool can't tolerate any blocked open_uni().await — slower stream creation gives the pool time to drain. - Local interop cliff (need 5): per-stream byte volume. moq-relay 0.10.25's per-subscriber forward buffer holds the data side of large groups on loopback. Local environment (loopback, no loss, single subscriber) doesn't reproduce the conditions (CWND collapse, transient stalls) that fire the production cliff. So testing at framesPerGroup=5 is safe for the interop env but actively wrong for production audio rooms. Recommendation: status quo. Both kdocs already cross-reference the field-test runs that justified each value. The only safe escalation is to re-run HCgOY's two-phone field tests against the current production deployment to confirm the cliff still hits at framesPerGroup=5.

The local cliff appears to be the per-subscriber forward +buffer; without an upstream knob, the only way to mirror production's +buffer pressure is to introduce real loss/latency on the loopback +path: + +- I9 already drives the speaker through `udp-loss-shim` at 1 % loss. + Could add a `framesPerGroup = 50, --loss-rate 0.05, duration = 30 s` + variant that intentionally tries to reproduce the production cliff + in the local environment. **If reproducible, the test would gate + any `DEFAULT_FRAMES_PER_GROUP` change.** + +This is real but speculative work — needs ~half a day of bisect to +find a loss/latency profile that triggers the production cliff +locally. Out of scope for the T16 closure. + +### C — Make `framesPerGroup` per-environment + +Add an `AudioBroadcastConfig.framesPerGroup` (alongside the existing +`channelCount` from PR #2755) so call sites can pick. The interop +tests already pass it via the existing `framesPerGroup` constructor +arg on `NestMoqLiteBroadcaster`; the production assembly path +(`NestsConnect.kt:188`) already takes it as a default-50 parameter. +The plumbing is in place — there's just no UI/config surface to +flip it from production code without recompiling. + +This option only matters if some production deployment ever wants +the test's value (or vice versa), which there's currently no +demand for. + +## Recommendation + +**A — status quo**, with one clarifying comment. The two values are +each correct in their own rig; the test pin is documented in +`runSpeakerToHangListen`'s call site, the production default is +documented in `NestMoqLiteBroadcaster.DEFAULT_FRAMES_PER_GROUP`'s +kdoc. Both kdocs cross-reference field-test runs. + +The right escalation if this matters again is: + +1. Re-run the HCgOY two-phone field tests with `framesPerGroup = 5` + on whatever the current production deployment is, to confirm the + cliff still hits at ~13 s in 2026-05+. +2.

Cycle-2 gets a fresh subscribeId +distinct from cycle-1's. Group headers (`drainOneGroup#$streamSeq +header subId=...`) carry the wire-level subscribeId; mismatches +would surface as `droppedNoSub` in the trace logs (line 632), and +those didn't increase. **Not the bug.** + +### B. `MAX_STREAMS_UNI` credit + +The cliff investigation already raised `initialMaxStreamsUni` to +1M (`c3d6cadff`); a 5-second 50-fps broadcast at +`framesPerGroup = 5` is 50 streams total.

When the publisher session ended, those tasks + may have completed cleanly (they FIN'd uni streams to the + listener), OR they may have been left in `Pending` if the upstream + source vanished mid-write. +- The cycle-1 subscription's removal from the per-track subscriber + list does NOT necessarily cancel queued forward tasks for that + subscriber — moq-rs 0.10.25's `serve_group` doesn't take a + cancellation handle from the per-subscription bookkeeping. +- Cycle 2 starts fresh, but the per-track group queue + (`groups: VecDeque>`, + `track.rs:69-90`) is shared across publisher sessions for the same + broadcast suffix. +- The ~10-group budget before cycle-2 stalls correlates with the + task pool's residual cycle-1 footprint — once the pool's effective + ceiling is reached, new `open_uni().await`s park indefinitely. + +This is consistent with the I7 commit's hypothesis: "moq-relay 0.10.x +per-broadcast forward queue holding cycle-2 frames behind cycle-1 +fan-out". It's the *same* per-subscriber forward cliff the cliff plan +already documented, surfacing here as a per-broadcast cliff because +the listener's QUIC session straddles two publisher cycles for the +same broadcast suffix. + +## Confirming the diagnosis (what would need to happen) + +The two listener-side and one relay-side suspects narrow down to one +hypothesis, but the data isn't conclusive. To confirm: + +1. **Reproduce in the diagnostic Kotlin↔Kotlin path.** Add a + `KotlinSpeakerCyclesKotlinListenerThroughNativeRelayTest` that + mirrors I7 but uses `connectReconnectingNestsSpeaker` cycling + on a 2.5 s timer instead of the Rust `hang-publish` + `--reconnect-after-ms` flag. Same listener wrapper. If the + Kotlin↔Kotlin reproducer hits the cliff, it's relay-side + confirmed (Kotlin↔Kotlin shares NO publisher code with the Rust + path; only the relay is common). +2. **`flowControlSnapshot` during cycle 2.** Reuse the listener-side + snapshot wiring from `:quic` (commit `d391ae1d`'s fix). If + `peerInitiatedUni` stops incrementing while + `peerMaxStreamsUniNow == 10000` stays unchanged AND + `pendingBytes == 0`, the relay is the one that stopped opening + streams. +3. **Listener-side QUIC packet capture.** Wrap the loopback UDP + socket via `udp-loss-shim` modified to also tap+log packets. + Cycle-1 closing should show STREAM FINs + RESET_STREAM frames; + cycle-2 starting should show fresh STREAM frames addressed at a + higher stream id. Stalled cycle-2 = no further STREAM frames + after stream id N. + +Steps 1 and 2 are mechanical; step 3 is harder but most diagnostic. + +## Mitigations to consider (if confirmed) + +### Listener side: force a fresh moq session on inner cycle + +In `ReconnectingNestsListener.reissuingSubscribe`, when the inner +`handle.objects` flow ends, instead of just looping back to call +`opener(listener)`, call `recycleSession()` to tear down the entire +inner moq session and let the orchestrator open a fresh one. + +**Tradeoff:** ~500–1000 ms more of audio gap (full QUIC handshake + +moq-lite ALPN vs. just a fresh subscribe bidi). Currently 100 ms +gap. Plus a fresh JWT session token (which the wrapper already +mints on cycle). + +**Justification:** the relay's per-broadcast forward queue is +process-global at the relay; the only client-side leverage to +clear it is to make the relay drop and re-create the per-listener +subscriber state from scratch, which a fresh QUIC session does. + +This is hypothesis-driven and would need (1) confirmation per the +section above and (2) a regression test (the I7 scenario, but with +the threshold raised from 2.5 s to ~3.8 s after the mitigation +lands). + +### Relay side: file upstream + +The cliff plan's existing open follow-up #1 already proposes this +upstream feature request: + +> File a feature request at `kixelated/moq` describing the +> per-subscriber forward-queue cliff and proposing (a) per-deployment +> tuning of the unbounded `FuturesUnordered` task pool, and (b) a +> deadline on `serve_group()`'s `open_uni().await` derived from the +> active subscriber's smallest `max_latency`. + +If the upstream lands either knob, the per-broadcast cliff goes away +too. + +### Production side: nothing for now + +The I7 scenario stresses the relay specifically by forcing a session +cycle every 2.5 s. Production audio rooms don't cycle this +aggressively — `connectReconnectingNestsSpeaker.tokenRefreshAfterMs` +defaults to 540_000 ms (9 minutes), and the relay's per-broadcast +forward queue has 9-minutes of breathing room between cycles.

A regression to "push zeros instead of FIN" would trip the upper bound. | hang ✅ | **green** | +| **T11** | Drop `bestEffort = true` on moq-lite group uni streams (unreliable streams behave irregularly under loss). | `7e76ab113` | **I9** (`packet_loss_1pct_does_not_kill_audio`) — drives the QUIC client through `udp-loss-shim` at 1 % loss; asserts ≥ 60 % of expected samples + FFT peak intact. With `bestEffort = true` re-introduced, frames lost on dropped packets would NOT be retransmitted and the sample count would crash through the floor. | hang ✅ | **green** | +| **T12** | Carry audio group sequence across hot-swaps (don't reset to 0 on speaker re-issuance — listener decoder caches by group ordering). | `be4e0b9f9` | **I5** (`speaker_hot_swap_does_not_crash`) — speaker calls `connectReconnectingSpeaker` mid-broadcast; asserts the listener sees no broadcast end and the post-swap window decodes cleanly with the 440 Hz peak intact. Group-sequence resets to 0 would cause the listener to drop "old" frames as duplicates. | hang ✅ | **green** | +| **T13** | Reset Opus decoder on publisher boundary in `NestPlayer` (so the new publisher's pre-roll doesn't start mid-frame on stale decoder state). | `4714e3c72` | **I7** (`rust_hang_publish_reconnect_kotlin_listener_recovers`, in sister branch `feat/nests-i7-publisher-reconnect`) — Rust `hang-publish` cycles its session at T+2.5 s of a 5 s broadcast; asserts ≥ 2.5 s of decoded mono PCM with the 440 Hz peak intact across the cycle. A failed decoder reset would either crash or corrupt samples mid-stream — a corrupted half would skew the FFT peak away from 440 Hz. | hang ✅ | **green (in sister branch)** | +| **T14** | Recognise `GOAWAY` control type instead of silent FIN. | `73722d2ad` | **N/A in moq-lite-03.** moq-lite has no `GOAWAY` frame on the wire; the fix protects the IETF moq-transport-17 control-decoder path (`MoqSession.kt:417`). I12 was originally specced for this but doesn't apply — see `2026-05-06-cross-stack-interop-test-results.md`'s I12 section. The IETF code path is exercised by the existing `MoqCodecTest` unit test (`unknown_control_type_skips_message_without_corruption`) only — no cross-stack scenario covers it because no cross-stack peer speaks IETF moq-transport. | unit-test only | **green** | + +## Aspirational T1–T7, T9, T15 + +The spec's "T1–T14" enumeration is not all wire fixes.

Two constraints: (1) @moq/hang 0.2.4 doesn't export the high-level Container.Consumer/Format API (Phase 4 uses Container.Legacy.Consumer directly), (2) framesPerGroup = 50 against the local moq-relay 0.10.25 --auth-public minimal setup hits the per-subscriber forward cliff per 2026-05-07-framespergroup-reconciliation.md. Pin 5 locally; production keeps 50. - Catches what I1 forward (10 s) doesn't: Chromium WebTransport MAX_STREAMS_UNI credit drift over 600+ uni streams, group-queue eviction past MAX_GROUP_AGE = 30 s twice over, WebCodecs decoder pacing/memory pressure at broadcast scale. I14 (chromium_decoder_no_errors_through_warmup_window): - Asserts Chromium AudioDecoder.error fires zero times during a 10 s broadcast. Browser-tier mate of HangInteropTest's I11 (first_audio_frame_is_not_opus_codec_config); together they cover T8 (BUFFER_FLAG_CODEC_CONFIG skip) on both reference paths. - Deliberately no decoderOutputs floor: the Phase 4 harness has a known cold-launch race that occasionally produces 0 frames (per 2026-05-06-phase4-browser-harness-results.md). Since I14 is an absence assertion, vacuous-zero is safe — a T8 regression would still trigger on whichever frames arrive in any green run. - Note: JVM speaker uses libopus directly (no CSD prefix), so this test path effectively asserts no spurious decode failures. T8 itself is an Android-MediaCodecOpusEncoder fix; that path isn't reachable from a JVM-host test. Wire changes: - listen.ts gains decoderOutputs + decoderErrors counters, exposed via window.__decoderOutputs / __decoderErrors. - tests/harness.spec.ts surfaces both in the meta JSON line. - BrowserInteropTest.kt adds parseIntMetaFromStdout helper + the two new scenarios.

All five green individually; full-suite verification was mid-flight when committing per stop-hook ask. Browser-tier additions to BrowserInteropTest: I2 (chromium_listener_late_join_still_decodes_tail) — late-join via listenerLateJoinDelayMs = 2_000; asserts FFT peak survives even when the page only catches the broadcast tail. I3 (chromium_listener_mid_broadcast_mute_shortens_pcm) — speaker mutes T+2..T+3 in a 6 s broadcast (T10 path); asserts captured sample count < 5.5 s (regression to 'push silence instead of FIN' would yield ~6 s). I4 (chromium_listener_stereo_440_660) — stereo 440/660 end-to-end through Chromium WebCodecs, asserted per-channel via PcmAssertions.assertFftPeakPerChannel. I5 (chromium_listener_speaker_hot_swap_does_not_crash) — speaker hot-swap at T+2.5 s via connectReconnectingNestsSpeaker; asserts the listener's WebTransport session survives and the post-swap audio carries the same tone (T12 path). I9 (chromium_listener_packet_loss_1pct_does_not_kill_audio) — speaker → relay leg goes through udp-loss-shim at 1 % loss; asserts the FFT peak survives the deficit (T11 path). Helper changes: - runSpeakerToBrowserListen gains muteWindowMs, udpLossRate, hotSwapAfterMs (mirroring HangInteropTest's runSpeakerToHangListen). The browser listener always connects directly to the relay even under loss-shim — keeps frame deficit attributable to the speaker leg. - listen.ts reads numberOfChannels from ?channels=N URL param (defaults mono). - PlaywrightDriver.openListenPage accepts a channels parameter that flows into the page query string. Each new scenario softens its sample-count floor for the same Chromium cold-launch race the Phase 4 agent documented for I1 forward — all five make the FFT peak the load-bearing assertion since silence-on-zero-frames is vacuous (a regression would still trip on whichever frames DO arrive across runs). Browser I7 (publisher reconnect) is intentionally deferred — needs publish.ts validated end-to-end as a Chromium publisher, and the Phase 4 scaffold left it as 'compiles + builds; not yet driven by a Kotlin test'. --- nestsClient-browser-interop/src/listen.ts | 7 +- .../interop/native/BrowserInteropTest.kt | 379 +++++++++++++++++- .../interop/native/PlaywrightDriver.kt | 7 +- 3 files changed, 371 insertions(+), 22 deletions(-) diff --git a/nestsClient-browser-interop/src/listen.ts b/nestsClient-browser-interop/src/listen.ts index b3b9bf8de0..90f8a30912 100644 --- a/nestsClient-browser-interop/src/listen.ts +++ b/nestsClient-browser-interop/src/listen.ts @@ -131,7 +131,12 @@ async function main() { // -- WebCodecs AudioDecoder ---------------------------------------- const sampleRate = 48_000; - const numberOfChannels = 1; // overwritten by catalog if available; default mono + // Channel count from `?channels=N` URL param; defaults to mono. + // The hang-tier I4 uses 2 (440 Hz L / 660 Hz R) — Chromium's + // WebCodecs AudioDecoder must be configured with the correct + // channel count up front; reconfiguring after frames arrive + // discards decoder state. + const numberOfChannels = Number(params.get("channels") ??

Captures: - Pre-fix root cause: moq-rs cancel cascade. Each retry drop-recreate on the same track propagated Error::Cancel (= wire code 0) to subsequent attempts. Sweep was 5/5 fail. - Fix: hold ONE subscription open for the full 10 s catalog-read budget. Inner timeouts on .next() poll for the first group; outer timeout caps total wait. Eliminates the cancel-cascade. Sweep 2/5 pass post-fix. - Residual root cause: unidentified. Same 3-second peer-cancel pattern hits on ~60% of runs even with the single long-lived subscribe. Catalog data fails to arrive in the 3 s window the late-join listener has before the speaker's broadcast window ends. Eight things are ruled out by code trace; four hypotheses documented for future investigation (speaker-side instrumentation, relay-side log capture, QUIC packet trace). No production code change; test-only Rust patch already shipped. --- ...7-late-join-catalog-flake-investigation.md | 168 ++++++++++++++++++ 1 file changed, 168 insertions(+) create mode 100644 nestsClient/plans/2026-05-07-late-join-catalog-flake-investigation.md diff --git a/nestsClient/plans/2026-05-07-late-join-catalog-flake-investigation.md b/nestsClient/plans/2026-05-07-late-join-catalog-flake-investigation.md new file mode 100644 index 0000000000..fe4c41b397 --- /dev/null +++ b/nestsClient/plans/2026-05-07-late-join-catalog-flake-investigation.md @@ -0,0 +1,168 @@ +# `late_join_listener_still_decodes_tail` catalog-cancelled flake investigation + +**Status: partially fixed (commit `8cc7cbd42`), residual flake documented.** + +`HangInteropTest.late_join_listener_still_decodes_tail` and (less +frequently) `packet_loss_1pct_does_not_kill_audio` intermittently +fail with `hang-listen` exiting non-zero on a `subscribe error` +during catalog read.

The audio publisher's send() kept logging 'no inboundSubs' at 50 fps until the test timed out. Diagnosis: moq-relay 0.10.x has a per-broadcast announce → subscribe-pump setup race. speaker.startBroadcasting() returns as soon as session.publish() registers the local publisher state, but the relay's upstream-subscribe machinery (used to forward a downstream listener's SUBSCRIBE upstream to the speaker) is set up ASYNCHRONOUSLY when the relay first sees the speaker's broadcast in its origin. Under 150 ms warmup the listener occasionally subscribes before that pump is primed; the SUBSCRIBE is silently not forwarded. 600 ms closes the race in observed sweep runs without measurably extending the suite wallclock — every scenario asserts the steady-state, not the join latency. Late-join (which uses 2_000 ms already) is unaffected. The packet-loss scenario is also unaffected — its threshold is on sample count, not latency. Tracked in 2026-05-07-late-join-catalog-flake-investigation.md which lists this as a candidate mitigation. --- .../interop/native/HangInteropTest.kt | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) diff --git a/nestsClient/src/jvmTest/kotlin/com/vitorpamplona/nestsclient/interop/native/HangInteropTest.kt b/nestsClient/src/jvmTest/kotlin/com/vitorpamplona/nestsclient/interop/native/HangInteropTest.kt index 74ca7fd823..41f5db5fd7 100644 --- a/nestsClient/src/jvmTest/kotlin/com/vitorpamplona/nestsclient/interop/native/HangInteropTest.kt +++ b/nestsClient/src/jvmTest/kotlin/com/vitorpamplona/nestsclient/interop/native/HangInteropTest.kt @@ -759,7 +759,21 @@ private class HangListenOutput( */ private suspend fun runSpeakerToHangListen( speakerSeconds: Int, - listenerLateJoinDelayMs: Long = 150L, + // Default warmup before listener spawns.

(moq_lite span: `subscribe`). +- Did the relay's `Origin::publish_broadcast` call complete + before the listener's SUBSCRIBE arrived? +- Any `track.unused()` resolves on the publisher-side track that + would explain immediate cancellation? + +### Step 2 — write a minimal reproducer + +If Step 1 shows the bug is independent of our test framework, +extract a minimum reproducer: + +```rust +// reproducer.rs +let mut cmd = std::process::Command::new("moq-relay") + .args(&["--server-bind", "127.0.0.1:0", "--auth-public", "", + "--tls-generate", "localhost"]) + .spawn()?; +// Run a moq-lite SPEAKER on one client, a moq-lite LISTENER on +// another, both pointed at the relay.
