EXTRACTED METHOD: map_orbital_periods_to_e8 — E8 Intelligence Research

rule: For each planet, compute ratio of sidereal period to Earth year, then find nearest integer multiple of 8 (e.g., 29.46 -> 30, 30*8=240). Flag if ratio is within 0.05 of an integer. source: rlab #485 Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
