tri_recover.py parses each payload's stride-0x10 edge groups {scale,A,B,C}
(GOODEQNS edgeize output), solves the three edge equations pairwise into true
vertices, and fills the triangles. cap7's bench = a triangulated calibration
grid + a multi-part test model + triangle strips, in global screen coords --
the image Division's engineers used to validate VelociRender boards, exact to
the compiled coefficients. The earlier 9x5 patch was one corner of this scene.
Readout gains §06 (test pattern) with trek/klng scenes moving to §07. The demo
captures' streak/point payloads use a different layout (parser refinement
pending) -- the bench is pure triangles and recovers perfectly.
