about
nx_gx_firstbyte_gate.nx -- Gx re-grounding: the sovereign graphics stack proven FROM THE FIRST BYTE UP.
One canvas, seven panels, each a rung of the chain -- byte0 marker / scanline gradient / framebuffer checksum /
triangle raster (count vs analytic area) / z-buffer (near wins though far drawn LAST) / per-pixel lit sphere /
SSS wrap vs clay -- then the PNG artifact's OWN first byte (0x89 magic) is read back and verified. Every rung
is measured in-gate, not asserted; the composite PNG is the eyeball artifact. HONEST: the deeper rungs
(GGX BRDF, browser compositing, PBR) stay in their own gates -- this is the trunk they stand on.
