The first end-to-end run of lumen's own protocol, past the GameStream compatibility layer. - lumen-core/src/quic.rs (behind the `quic` feature): the lumen/1 handshake — Hello/Welcome/ Start as length-prefixed LE binary on one QUIC bi-stream. Welcome carries the COMPLETE data-plane Config: mode, FEC scheme incl. GF(2^16) Leopard (inexpressible in GameStream), shard sizing, AES-GCM key + per-direction salt, data UDP port. Plus quinn endpoint helpers (self-signed server; accepts-any client — pinning lands with the trust model) and framed async IO. Round-trip unit-tested. - lumen-host m3-host: serves one lumen/1 session — QUIC handshake, then a NATIVE thread (no async on the frame path — design invariant) streams deterministic 64KB test frames through the hardened M1 Session over UdpTransport. - lumen-client-rs: from scaffold to working reference client — connects, negotiates, brings up the client Session over UDP, reassembles + FEC-recovers + byte-verifies every frame. VALIDATED END-TO-END on localhost: 300/300 frames verified, 0 mismatches, through QUIC-negotiated GF(2^16) FEC + AES-GCM over real UDP sockets. M4 (decode+present) builds on this exact client skeleton. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
