PR-GAP-2 Robson Gauge: Path-Type Plane

44 societies + USA, Iceland, ASPI & Cuba CAMS5 ensembles
η_soil (slow-node cultural grounding) × σ_V (node dispersion). Log η axis. Hover for detail.

Symbols

● Filled = clean data
◌ Dashed outline = scoring artifact flag
▲ Triangle = historical data only
Note on low-σ outliers. India, Thailand, Pakistan, Israel, Palestine show σ_V < 0.3, inflating η by suppressing the denominator. This is likely epoch-level scoring producing uniform node scores. Results should be treated as artifacts, not institutional findings.
