sandpile-utac
GenesisAeon Package 22 — BTW & Manna Sandpile as Continuous Phase Transition
Bak–Tang–Wiesenfeld & Manna sandpiles as UTAC phase transitions.
Key result: BTW Γ ≈ 0.296, Manna Γ ≈ 0.376 — anchors the CREP criticality spectrum.
Installation
pip install sandpile-utac
For development:
pip install -e ".[dev]"
Quickstart
sandpile-utac run --model btw --L 256
sandpile-utac phase-diagram
sandpile-utac crep-spectrum
Integration in genesis-os
from genesis_os import GenesisOS
os = GenesisOS()
sandpile = os.load_package(22)
results = sandpile.run_cycle(n_grains=10_000_000)
Benchmark
Validated against Phys. Rev. E (2025).
Falsifiable Prediction
Systems with η = 50 % converge to Γ ≈ 0.25 across all domains.
Role in the GenesisAeon Ecosystem
sandpile-utac is GenesisAeon Package P22, in the statistical
mechanics / self-organized criticality domain. It validates the UTAC
(Universal Threshold Activation Criticality) methodology against the
canonical Bak–Tang–Wiesenfeld and Manna sandpile models — the
prototypical self-organized-criticality benchmark — anchoring the CREP
Criticality Spectrum at Γ ≈ 0.296 (BTW) and Γ ≈ 0.376 (Manna).
