edge_verify.py: the edge SEND payload float 0.12527 matches the object's own
screen-space edge normal (0.12555, computed from the captured vertices) to
0.2%, and 0.1262 to 0.5%. Edges are pure screen geometry (no z-scale ambiguity),
so this is a hard confirmation that the compiled micro-code carries the real
coefficients. Readout §02 states the 0.2% match.
