What It Measures

How constrained the data's 8-byte structure is relative to the densest sphere packing in 8 dimensions.

Takes each group of 8 consecutive bytes, normalizes them, and finds the closest of the 240 root vectors of E8. These roots come in two families: 112 "integer" roots (pairs of coordinate axes) and 128 "half-integer" roots (all coordinates ±1/2 with even sign parity). The geometry also snaps each 8-byte window to the nearest actual E8 lattice point via parity correction, measuring the residual distance. Data with algebraic constraints concentrates on a few roots; unconstrained data spreads evenly across all 240.

Metrics

std_profile

Variation in root alignment quality across windows, capturing how consistently the data's 8-byte structure matches E8 directions. High for signals with a mix of aligned and unaligned windows.

coset_transition

Rate at which consecutive windows switch between integer and half-integer root cosets. Measures temporal dynamics of parity structure. Evolved via ShinkaEvolve.

diversity_ratio

Fraction of the 240 E8 roots actually used. High diversity means the data explores the full root system; low means it's confined to a subspace.

normalized_entropy

Shannon entropy of root usage, normalized by maximum. Uniform distributions across 240 roots score high; periodic orbits score near 0.

e8_structure_score

Combined structural score from root alignment, coset dynamics, and lattice closure. Evolved via ShinkaEvolve. Not yet in the atlas.

closure_score

How closely the lattice-snapped points recover the original data. Evolved via ShinkaEvolve. Not yet in the atlas.

edge_flow

Net directional flow along E8 root graph edges over time. Evolved via ShinkaEvolve. Not yet in the atlas.

trajectory_curvature

Mean curvature of the trajectory through E8 root space. Evolved via ShinkaEvolve. Not yet in the atlas.

vel_corr

Autocorrelation of the velocity (root-to-root distance per step) sequence. Evolved via ShinkaEvolve. Not yet in the atlas.

When It Lights Up

E8 Lattice is the highest-dimensional root system geometry in the framework (window size 8), complementing G2 (2), H3 (3), D4 and H4 (4). Its 240-root system is the densest lattice sphere packing in 8D, and the coset_transition metric captures temporal structure in how the data moves between the integer and half-integer sublattices — a signature that lower-dimensional root systems cannot detect.
