Production sweep on commit c0269859 confirms the MAX_STREAMS_UNI fix landed:
- sweep_frames_200: received=200/200 missing=[] ✅
- sweep_baseline 100×20ms: received=100/100 ✅
- sweep_2subs (both subscribers): 100/100 each ✅
- sweep_cad{10,40,80,200}: all 100/100 ✅
- sweep_payload_{1kb,4kb}: 100/100 ✅
- sweep_slowconsumer: 100/100 ✅
14 of 27 scenarios now deliver 100% of frames. The original "audio cuts
out at frame ~99 in two-user rooms" bug — the practical user-facing
issue — is fixed.
Residual loss in extreme scenarios (long broadcasts, very large payloads,
mid-stream pauses, fast bursts, multi-subscriber asymmetry) is documented
in the plan doc with three hypotheses to test next:
1. Listener QUIC RX coalescing / UDP socket recv overhead
2. Receive-side MAX_STREAM_DATA extension threshold
3. moq-rs relay's per-subscriber buffer policy
Next step is separate investigation; the speaker side is now
demonstrably pristine (pendingBytes=0, consumed grows monotonically,
nextLocalUniIdx matches the frame count) so further work is on the
listener-RX or relay-forward side.
