User-provided ground truth: the cap7 test scene displays SMPTE colour bars.
Axis-alignment census (8/196 axis-aligned) proves the recovered triangles are
the 3D test-scene layer, not the bars -- the bars are the OUTPUT of the
standard background program (the byte-identical bit-serial SENDE/SEND set in
every capture: a video test card painted as the permanent backdrop, colours
written to the eofr/g/b planes 184/192/200 by the x2-chain sweeps). Payload
formats settled: size-18 = 3 edges + z-plane; size-21 = 3 edges + texture-ramp
SCALAR plane (the pvision mechanism). The known bar pattern is now the
pixel-exact acceptance oracle for the bit-serial program executor (the
chartered IGC_* macro work). Readout §06 caption updated.
