What it is
Atoms drift with realistic physics and bond automatically on proximity by valence rules. Particle Physics Sandbox is a core component of the P31 Labs sovereign cognitive infrastructure stack — built to run offline, deployed to the edge, and designed without dark patterns.
Canvas 2D with a custom Verlet integration physics loop. Valence bond rules are a lookup table keyed by element pair. Zero external dependencies.
