The emulated VPX board now draws frames in real time. The FIFO burst
assembler feeds an in-process DPL scene store; each vr_draw_scene publishes a
frame snapshot to a dedicated WGL window thread that renders it fixed-function.
- vpxlog.cpp: scene_burst() decode + VScene store + rt_main GL window thread;
glFrustum from the view-node window rect, glScalef(-1,1,1) for Division's
mirrored screen-x, action-31 camera as modelview. No build change (opengl32
already linked).
- Validated: flyk divrgb.scn opens the "VPX VelociRender (emulated)" window
and draws the SMPTE bars live via the real camera.spl spline camera
(divrgb-live-gl.png), matching the offline render_capture.py decode.
- Game path (alpha1.conf) opens the window + draws background but hits the
pre-existing production btdpl.ini vr_sync timeout (sends_wo_rcv) -- not a 3b
issue. Remaining work tracked in PHASE3-PROGRESS.md.

- vpxlog.cpp: VPX_FIFODUMP=<path> records every FIFO burst ('VPXM' records)
- decode_fifodump.py: action census + payload dumps of a capture
- render_capture.py: reconstruct the DPL scene graph from a capture and
software-render each draw_scene frame (camera, view, materials, geometry
all taken from the wire)
- divrgb.conf + divrgb.fifodump: flyk divrgb.scn capture fixture
- divrgb-decoded.png / divrgb-frame0.png: first images ever produced from
the Rel 4.10 VPX protocol without a real board -- the textbook SMPTE
color-bar pattern, validating verts/conns/materials/camera in one shot
- PHASE3-PROGRESS.md: the established Rel 4.10 wire protocol (action map,
node types, message layouts); RENDER-HARNESS.md updated
