Summary

Replaces the closed control-stream mic approach with a real media-plane uplink.

  • Wire (Foundation-compatible): MIC_STREAM_PORT = base+12, RTSP DESCRIBE mic m-line, SETUP mic
  • Host sink: Steam Streaming Microphone only (no VB-Cable auto-install)
  • Discovery: /serverinfoMicrophoneCapable / MicrophoneReady / MicrophonePort
  • RS-FEC: opportunistic per-session when parity shards are present — not advertised
  • Design notes: docs/mic/uplink-rtp.md

Test plan

  • CI Windows build (mic-ci or PR CI)
  • Foundation client: enable mic, confirm host Steam mic receives audio
  • Without Steam: Ready=0, SETUP still completes, no crash
  • serverinfo fields present over HTTPS

serverinfo Capable/Ready/Port). Host sink is Steam-only (no VB-Cable).
RS-FEC is opportunistic per-session when parity shards appear; not advertised.
