The passage around this formula
The initial simulation uses a spin- j coherent state as a finite directional reference and N sequential spin-one-half probes. That choice intentionally restricts the first result to . Calling it a full SO(3) frame would add an unencoded rotation about the spin axis. A later quantum-rotor or asymmetric-top model can carry a triad after the directional pipeline passes its tests.
