An Operational Length Anchor D: Identifiability, Cross‑Invariants, and an Adoption Algorithm — Source & Data (v1.0)

What this is. Fully reproducible Source & Data package for the MST manuscript “A fit‑free acceptance protocol for interferometric scale estimation: the operational anchor D, cross‑invariants, and a MODE gate (Option–B)”. The decision rule is Bonferroni‑controlled Student‑t CI intersection over (A,B,C) with a diameter bound; the MODE gate provides operational identifiability. (Eq. (2)–(4); MODE Z‑bound is a sufficient feasibility bound only; final adoption uses t‑CI.) LYJ_MST_anchorD MST_cover_letter_OptionB_YJLee Contents. config/thresholds.yaml (pre‑registered; ε=1.10e‑3, ρ_BC switch=0.98), scripts/*.py, results/*.csv (VM nominal), figs/*.png, CITATION.cff, manifest.json, README.md. Reproducibility (numbers in the paper). Under the registered nominal profile, our re‑decision strictly following Eq. (2)–(3) yields: MODE‑PASS 99.7%, AB‑fallback 0.0%, d²(95%) 6.0347, CI‑diameter p50/p95 = 1.108e‑3 / 1.309e‑3, FRR 51.75% (K=2000; results/vm_nominal.csv). The manuscript’s Appendix E.3/E.5 values have been updated accordingly. LYJ_MST_anchorD How to run. Python ≥3.11, pip install -r requirements.txt (note: versions not hard‑pinned). python scripts/reproduce_figures.py to regenerate Figs 1–6; python scripts/vm_sweep.py for sensitivity sweeps; python scripts/vm.py for the nominal VM set.
