Interface with gravax

San Diego State University

progenax produces pure physical state — positions, velocities, masses, stellar radii — packaged as an immutable ICResult PyTree with no dependency on gravax. That state is exactly what an N-body integrator consumes, so the eventual handoff is a thin adapter (ParticleSystem.from_ic(ic, units=STELLAR) in gravax) rather than anything progenax must own.

Until that recipe lands, the API reference documents the ICResult fields, and Set up a virial-equilibrium cluster shows how to build the IC you would hand off.
