The spectral fingerprint of the orderings

The personality of each ordering, in three spectra

Choose an ordering and compare its fingerprint: the Walsh energy bars, the dominant DFT harmonic and the Haar scale.

The family tree measures the kinship between orderings by inversions. This is its other face: the personality of each one, by spectrum. With a common yardstick for all five (position → binary value, centred), we extract three signatures: the energy of Walsh by order of line interaction, the dominant harmonic of the DFT and the scale of the dominant Haar wave.

Declared convention: this signal (the value placed at each position) is different from the one in Fourier over the cube and in the ring (position → King Wen number). There the structure of the book's content is measured; here the same yardstick is needed to compare the five orderings, so the signal is the value itself placed at each position.

What the signatures say

Jing Fang is the anti-linear one. 0% of linear energy and 74.5% in interactions of 4 lines: the loner of the brotherhood also has the strangest signature, and now one can see why its path sounds different.

King Wen resonates at k = 16 (period 4), at the same scale as the groups of 4 that Chan (2026) detects by another route: two independent methods pointing to the same scale.

Fu Xi and Gray calibrate the system. Fu Xi is a pure tone (100% linear, a single harmonic) and Gray almost linear (75% of order 1): the yardsticks against which the personality of the rest is read.
