live_render.py connects to vpxlog.cpp's existing VPX_FIFOSOCK tee (the DOSBox-X
C012 device), consumes the game's wire AS IT ARRIVES, and runs the firmware and
the socket CONCURRENTLY -- pumping the socket whenever the firmware's receive
point drains -- rendering each draw with the shared verified GPU raster.
gpu_raster.py factors the M4c-raster renderer out of m4b_gpu so offline and live
share ONE render path (the 6-edge fp64 raster + verified texel decode).
feed_sock.py mimics vpxlog's FIFOSOCK server (streams a real capture in delayed
chunks) so the live path is validated end-to-end WITHOUT the flaky live pod.
Result: 12 frames streamed live at 2.3 fps; with --pin (equalized texture
availability) the live frames are BIT-IDENTICAL to the offline reference
(12/12 differ>24 = 0.000%) -- the seam is faithful. The default incremental
texture model is more authentic (the board only has texels it has received);
its divergence from offline is purely the M5-B tid%ntex placeholder, orthogonal.
Live topology now closed end-to-end offline:
game/capture -> C012 VPX_FIFOSOCK -> live_render -> firmware -> GPU -> frames.
