LQ8 INTERFACE REPRODUCTION PACKAGE
Research snapshot: 5 September 2026
https://emergent-gravity.com/research/

This package reproduces the eight fixed-mean interface equilibria and the
spatial infrared integral. It is not a three-dimensional gravity solver.
It does not regenerate the astronomical comparisons from raw observations.

Use Python 3.12. From this extracted directory:

python3.12 -m venv .venv
source .venv/bin/activate
python -m pip install -r requirements.txt
python verify_inputs.py
python -W error dark_equilibrium.py --pilot --output outputs/pilot

For the full calculation:
python -W error dark_equilibrium.py
python -W error dark_spatial_ir.py

The first full command writes outputs/dark_equilibrium/summary.json.
The second writes outputs/dark_spatial_ir_summary.json.
The published reference results remain in expected/.
The source and input tables are unchanged from the published calculation.
The scripts include assertions; warnings are promoted to errors above.
Runtime depends on the machine and BLAS implementation.
Compare numerical values using the published tolerances, not whole-file hashes
of regenerated output: wall times and floating-point rounding can differ.

Expected results: eight stationary solutions, maximum residual 9.614e-10,
positive constrained curvatures, maximum relative refinement change 4.48e-6.
Infrared coefficient at Q=1e-4: 0.1243973182; limit: 0.1243796488.
