One glyph per decan. Each carries two rulership registers at once, written as sidedness — the outer polygon its Triplicity Ascent ruler, the inner star its Chaldean traveler, both as the planet's kamea number. Nothing in an Atom is decorative.
Where the two registers are in unison — nine of the thirty-six — the figure is a self-similar nest. Stillness. Where they share a factor, the figure locks. Where they are coprime — eighteen of the thirty-six — nothing aligns, composite symmetry collapses, and the figure hums.
A glyph is fully determined by element, outer and inner: twenty-eight distinct designs across the thirty-six decans, in eight twin pairs. Identity is the grammar classifying, not a defect.
