Atomic Circle of Fifths

Exact D7 action on the seven-state p-occupation carrier. The fifth-order reader is a lawful seven-cycle; the mirror is particle–hole reflection about half filling. This is descriptor geometry, not atomic transmutation or pitch physics.

Claim boundary. Fp and Rp act exactly on the admitted occupation coordinate N∈{0,…,6}. Shared position, parity, or term-family read does not identify complete atomic Hamiltonians, spectra, energies, radial structure, nuclear witnesses, or physical states. The circle-of-fifths name is a declared reading order on a seven-cycle.
