This repository provides a runnable scaffold for the UCL GW Repro‑Kit. Phase 0 goals:

• minimal, deterministic environment (environment.yml)
• make repro-min runs three QA stubs: Flux-Ratio, Lock-Check, Slope-2
• make baselines runs lock-check on three frozen baselines (GR/Horndeski/DHOST).

cd ucl-gw
# (optional) conda env create -f environment.yml && conda activate ucl-gw
make repro-min      # produces reports/* and figs/*
make baselines      # lock-check on three baseline models

Outputs:

• reports/flux_ratio.json
• reports/lock_check.csv
• reports/slope2.json, reports/nlo_onepager.md, figs/nlo_slope_fit.png

NOTE: All configs are JSON stored in .yaml files (YAML superset) to avoid external parsers in Phase 0.
