What It Measures

Whether 3-byte patterns prefer icosahedral directions.

Projects each triple of consecutive bytes onto the 30 roots of H3 — the vertices of an icosidodecahedron. These roots split into 6 axis-aligned vectors (permutations of (1,0,0)) and 24 "golden" vectors involving the golden ratio (even permutations of (1/2, phi/2, 1/2phi)). H3 is the symmetry group of the icosahedron, featuring 5-fold rotational symmetry that no crystallographic lattice can achieve. The geometry asks whether the data's 3-byte structure has any preference for these non-crystallographic directions.

Metrics

nn_enrichment

Nearest-neighbor enrichment: how much more likely are consecutive windows to share a root than expected by chance. Measures temporal locality in root space. Evolved via ShinkaEvolve.

temporal_coherence

Autocorrelation of the root assignment sequence. High for smooth signals where 3-byte windows change gradually; low for noise and chaos.

path_closure

How often the root-space trajectory returns near its starting point over various time horizons. Captures periodicity and recurrence in 3D root coordinates.

normalized_entropy

Uniformity of root usage across all 30 H3 roots. Periodic orbits score near 0 (all weight on one root); high-entropy sources spread across many roots.

diversity_ratio

Fraction of the 30 H3 roots actually used. Complements normalized_entropy: diversity_ratio measures how many roots appear at all, while entropy measures how uniformly they are used.

When It Lights Up

H3 is the only geometry in the framework probing 5-fold icosahedral symmetry at the 3-byte scale, between G2 (pairs) and D4/H4 (quadruples). The evolved metrics (nn_enrichment, temporal_coherence, path_closure) shift focus from static root statistics to temporal dynamics in root space — how the signal's trajectory through the 30 icosahedral directions evolves over time.
