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.
