Gravity: Information-Limited Gravity (ILG) – Production

This repo contains a top-level production pipeline to reproduce the galaxy rotation results and artifacts referenced in the paper.

• Scripts: active/scripts/
  • build_sparc_master_table.py
  • ledger_final_combined.py
  • reproduce_048_fit.py
  • visualize_best_fits.py
  • plot_example_rc.py
  • make_release_bundle.sh
• Data: active/data/Rotmod_LTG (symlink to SPARC-like rotation curves)
• Results: active/results/ (master table, combined solver outputs, reproduction artifacts)
• Paper sources: active/paper/ (dark-matter-galaxy-rotation.tex, Gravity-derived.tex)

Legacy materials are preserved under archives/.

Quickstart

1. Create a venv and install requirements:

cd production
python3 -m venv env/.venv
source env/.venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -r env/requirements.txt

2. Build the master table and make an example figure:

cd scripts
python build_sparc_master_table.py
python plot_example_rc.py  # emits ../results/example_rc.pdf

3. Run the combined solver:

python ledger_final_combined.py
# Outputs to ../results/

4. Reproduce the 0.48 fit and visualize:

python reproduce_048_fit.py
python visualize_best_fits.py
# Outputs to ../results/

5. Create a release bundle (paper + scripts + minimal artifacts):

chmod +x make_release_bundle.sh
./make_release_bundle.sh
# Archives under active/results/release/

Notes

• Legacy docs moved to archives/legacy/.
• .gitignore excludes local virtualenv under active/env/.venv/.
• For reproducibility, pin your environment or use containers if desired.

Structure

• active/: current pipeline (scripts, data link, results, paper)
• legacy/: archived materials (archives moved here)
