feat(nests): T16 Phase 2 — JVM Opus + Rust↔Rust E2E interop test
Lands the test-side audio codec + the first end-to-end interop scenario through the harness: - JvmOpusEncoder / JvmOpusDecoder via club.minnced:opus-java 1.1.1 (JNA bindings + bundled libopus.so / .dylib / .dll natives). 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. Documented in nestsClient/plans/2026-05-06-cross-stack-interop-test-results.md with concrete pickup steps for a follow-up session. https://claude.ai/code/session_01ERJPUYfdLPwZ99pr5EcEcV

|

# Plan: cross-stack interop test (T16) — Phase 1 + Phase 2 results
|
||||
|
||||
**Status:** Phase 1 landed (scaffolding-only). Phase 2 + 3 + 4 + 5 deferred.
|
||||
**Status:** Phase 1 + most of Phase 2 landed. Phases 3–5 still deferred.
|
||||
|
||||
## Phase 2 update
|
||||
|
||||
Added on top of the Phase 1 scaffolding:
|
||||
|
||||
- **`hang-listen` real body** — connects to a `moq-lite-03` relay,
|
||||
reads the hang catalog, picks the first Opus / Container::Legacy
|
||||
audio rendition, decodes each Opus packet via the `opus = "0.3"`
|
||||
crate, and writes Float32 little-endian PCM to `--output-pcm`.
|
||||
- **`hang-publish` real body** — claims a broadcast, publishes a hang
|
||||
catalog with one Opus rendition (track name configurable via
|
||||
`--track-name`, default `audio/data` to match Amethyst's
|
||||
`MoqLiteNestsListener.AUDIO_TRACK`), encodes a sine wave with
|
||||
libopus, and pumps Opus frames in 5-frame groups for `--duration`
|
||||
seconds. Uses `audiopus`-equivalent `opus = "0.3"`.
|
||||
- Both binaries explicitly install the rustls aws-lc-rs crypto
|
||||
provider (rustls 0.23 no longer auto-installs) and use
|
||||
`--client-version moq-lite-03` + `--tls-disable-verify=true`
|
||||
to interop with the harness's self-signed `--tls-generate localhost`
|
||||
relay.
|
||||
- **JVM Opus encoder/decoder** via `club.minnced:opus-java:1.1.1`
|
||||
(JNA bindings + bundled libopus.so / libopus.dylib / opus.dll
|
||||
natives). Lives in `nestsClient/src/jvmTest/.../audio/JvmOpusEncoder.kt`
|
||||
+ `JvmOpusDecoder.kt`. Verified by
|
||||
`JvmOpusRoundTripTest.sine_440_round_trips_through_libopus` —
|
||||
encode → decode preserves the FFT peak at 440 Hz and the
|
||||
zero-crossing rate at 880/sec within 5%.
|
||||
- **Real-time pacing** in `SineWaveAudioCapture` — `readFrame`
|
||||
blocks until the next 20-ms boundary, mirroring how a microphone
|
||||
source paces. Without this the broadcaster's read loop would
|
||||
flood the relay with millions of frames/sec.
|
||||
- **`HangInteropTest.rust_hang_publish_to_rust_hang_listener_round_trip_440`**
|
||||
— Rust↔Rust round-trip through the harness. Spawns `hang-publish`
|
||||
+ `hang-listen` as subprocesses, asserts the decoded PCM has FFT
|
||||
peak at 440 Hz, ZCR at 880/sec, and 5 s of samples (±20% slack
|
||||
for Opus look-ahead + relay buffering). Verified green on Linux
|
||||
x86_64.
|
||||
|
||||
## Known gap — Amethyst speaker → hang-listen (I1 forward direction)
|
||||
|
||||
Wired in `HangInteropTest` initially as
|
||||
`amethyst_speaker_to_hang_listener_static_tone_440` but it doesn't
|
||||
pass yet. Symptom: the hang `Container::Legacy` decoder receives
|
||||
each `moq-lite Group { subscribe, sequence }` control message but
|
||||
never receives the per-frame `varint(timestamp_us) + opus` payload
|
||||
that should follow on the same uni stream. Both sides agree on
|
||||
`moq-lite-03`, the audio rendition catalog parses correctly, the
|
||||
audio SUBSCRIBE registers on the speaker's audio publisher
|
||||
(`inboundSubs.size=1`), and the broadcaster's send loop reports
|
||||
50 frames/sec going out — yet hang-listen sees no
|
||||
`varint(size) + bytes` after each Group header.
|
||||
|
||||
The race fix in the test (`speaker.startBroadcasting()` before
|
||||
spawning `hang-listen`) is needed to keep the catalog publisher's
|
||||
`setOnNewSubscriber` hook installed in time, but doesn't unblock
|
||||
the audio path. The catalog uni stream's frame data DOES make it
|
||||
through — only the audio uni stream's frames are lost. The bug is
|
||||
likely in `:nestsClient`'s audio uni-stream framing (in
|
||||
`MoqLiteSession.openGroupStream` / `PublisherStateImpl.send`) and
|
||||
needs a wire-byte capture against the existing Kotlin↔Kotlin
|
||||
listener path to confirm the issue is symmetric (i.e. only Rust
|
||||
fails to read) or producer-side (Kotlin fails to write the frame
|
||||
size prefix the way the spec calls for). The smoke-test version
|
||||
`HangInteropTest.rust_hang_publish_to_rust_hang_listener_round_trip_440`
|
||||
proves the harness + cargo workspace + JVM Opus all work; the
|
||||
Kotlin-speaker path is gated behind this open issue and tracked
|
||||
in this doc.
|
||||
|
||||
When picking up: replace the test body with the speaker-→-listener
|
||||
shape from the plan's "Patterns" section (already prototyped in
|
||||
the deleted `amethyst_speaker_to_hang_listener_static_tone_440`),
|
||||
and capture the first audio uni stream's bytes via a custom
|
||||
`WebTransportFactory` that sniffs writes — then compare against
|
||||
what the Rust subscriber's `run_group` parser expects.
|
||||

||||
