From cb6b1d9bbb1af27e4b70c19cd209f3323519469e Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 6 May 2026 21:49:58 +0000 Subject: [PATCH] =?UTF-8?q?feat(nests):=20T16=20Phase=202=20=E2=80=94=20I1?= =?UTF-8?q?=20amethyst=20speaker=20=E2=86=92=20hang-listen=20green?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bisected the I1 forward-direction failure to `framesPerGroup` cardinality, not a wire-format defect. 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.
