vrig-cosmological

v_RIG cosmological velocity scale — v_RIG = c / (α⁻¹ · Φ) ≈ 1352 km/s

A falsifiable cosmological velocity scale derived from the fine-structure constant α and the golden ratio Φ. Implements the Fisher-Rao information- geometric interpretation, ERA5-style spike detection, and cosmological survey comparisons. GenesisAeon Package 31.

Installation

pip install vrig-cosmological

Usage

from vrig_cosmological import VRIGCosmological

sys = VRIGCosmological()
result = sys.run_cycle(duration_years=83.0)

print(sys.v_rig_value())   # ≈ 1352.118... km/s
print(sys.spike_times())   # detected v_RIG spike years
print(sys.get_crep_state())
print(sys.to_zenodo_record())

Or use the calculator directly:

from vrig_cosmological import compute_vrig

result = compute_vrig()
print(result.v_rig_km_s, result.uncertainty_km_s)

A CLI is also available — see docs/cli.md.

Role in the GenesisAeon Ecosystem

vrig-cosmological is P31 in the GenesisAeon ecosystem, covering the information geometry / cosmological velocity domain. It implements the standard GenesisAeon Diamond Interface (run_cycle, get_crep_state, get_utac_state, get_phase_events, to_zenodo_record) so it can be orchestrated alongside other ecosystem packages (CREP coupling, UTAC state tracking, Zenodo-ready records).
