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.

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.
