Overview
This site documents the numerical simulation program for the paper “Gauging Time Reversal Symmetry in Quantum Gravity: Arrow of Time from a Confinement–Deconfinement Transition.”
All simulations use the ts-quantum TypeScript library for SU(2) algebra, intertwiner construction, and tensor operations.

Philosophy
- Unified code base — All simulations share a common core (intertwiners, operators, utilities)
- Incremental complexity — Start with exact diagonalization (T25), build to Monte Carlo (T20), then tensor networks (T21)
- Reproducible artifacts — Scripts, data, and figures versioned alongside the paper
- Web-deployed — Results published as they become available

Data Registry
All simulation runs are tracked in a central registry (data/registry.json) with: - Run metadata (ID, timestamp, parameters) - Output file references - Results summaries - Task/phase organization
This enables systematic collation and reproducibility as the simulation program scales.
