enricobuehler ab6dda2e5f feat: M0 capture→encode pipeline + M2 GameStream host (pairing, RTSP, video)
M0 (lumen-host) — verified on NVIDIA RTX 5070 Ti / Ubuntu 25.10:
headless wlroots → xdg ScreenCast portal → PipeWire → NVENC HEVC → playable file,
with each access unit round-tripped through a lumen_core host↔client Session
(FEC + packetize + reassemble), 0 mismatches.
- capture.rs: SyntheticCapturer + portal capture (ashpd 0.13 + pipewire 0.9), format-aware
- encode/linux.rs: NVENC via ffmpeg-next 7 (BGRx/RGB → rgb0, no host-side swscale)
- m0.rs: capture→encode→file + lumen-core loopback verification

M2 P1 (lumen-host gamestream/) — a stock Moonlight client pairs + launches, verified live:
- mDNS _nvstream._tcp + nvhttp /serverinfo (HTTP 47989, mutual-TLS HTTPS 47984)
- 4-phase pairing: PIN→AES-128-ECB / SHA-256 / RSA-PKCS1v15 / X.509, custom rustls
  ClientCertVerifier for the mutual-TLS pairchallenge
- /applist, /launch (rikey/rikeyid/mode), hand-rolled RTSP (OPTIONS/DESCRIBE/SETUP×3/
  ANNOUNCE/PLAY, one-request-per-TCP-connection per moonlight-common-c's read-to-EOF)
- video.rs: GameStream RTP + NV_VIDEO_PACKET wire packetizer, data-shards-only (0% FEC,
  clean-LAN), unit-tested (single/multi-block)

Docs: docs/m2-plan.md (phased plan) + docs/research/ (ground-truth protocol spec).
Bootstrap/setup updated for the verified path (libnvidia-gl, render/video groups, GPU
EGL, pipewire 0.9). Workspace clippy-clean, tests green.
