Reproducibility package (v4): Minimal rotational length selection under spectrally rotating forcing

This archive contains the reproducibility package (v4) for the manuscript “Minimal rotational length selection under spectrally rotating forcing.” It provides all materials needed to regenerate the main figures/tables and to verify the key control law L⋆ ∝ S^{1/2}. Contents (top-level): - JFM_DOI_FULLSTORY_v3.zip — main data/scripts used for gating the assertion - README_RUN.md, docs/README_v4.md — quick-start and notes - scripts/ (run_all.sh, assert_reproduction.py, analyze_dns_suite.py) - code/ (minimal DNS demo helpers) - data/dns_runs/ (small demo .npz files; illustrative, not used for gating) - requirements.txt, environment.yml, Dockerfile - logs/seeds.json, manifest.json, CITATION.cff How to reproduce (Option A: local) 1) Unzip this archive at a clean location. 2) From the top-level directory: export PYTHONPATH=code make # or: bash scripts/run_all.sh 3) The script prints slopes and writes figures/results into results/ and figs/. How to reproduce (Option B: container) 1) docker build -t jfm-v4 . 2) docker run --rm -it -v "$PWD":/work jfm-v4 bash scripts/run_all.sh Success criteria (automated check in assert_reproduction.py): - Main dataset (v3/data/L_S_table.csv): slope β ≈ 0.50 (bin-median + upper-quartile secant); OLS on binned medians ≈ 0.50 - Synthetic k^6: β ≈ 0.25 - Placebo S′: near zero using OLS / Theil–Sen on raw points Note: the small DNS demo in v4 is illustrative; the reproducibility assertion is gated on v3 data. Scope of reproducibility: We pin seeds and provide single-threaded settings in scripts to reduce numerical variation. Exact bitwise identity across all platforms is not guaranteed; following the steps above reproduces the reported slopes within the stated tolerances on a clean Linux/x86-64 environment.
