Build the six marked points, the retained major arc, and the two golden feet from the stated one-arcsecond construction.
Magnified seed inset, schematic scale only. The true opening is one arcsecond. Camera yaw does not move these marks.
Canonical coordinates. One-arcsecond seed, after the model pose. Binary64 preview. Camera and the 12° schematic do not change this table.

Selected measurements use the true seed: G = aφ = 1.618034, C = aπ = 3.141593, W = G + C = 4.759627. Outline length is different: a(2π − ε) + 2aφ² = 11.519248.
