Unreleased

src/fairness.py with fairness_metrics and decision_disagreement helpers for demographic-parity / equal-opportunity gaps and receiver disagreement.
Apache 2.0 LICENSE + NOTICE with third-party data attribution (German Credit / OpenML credit-g, Chiappa 2019 DAG).
data/README.md documenting dataset provenance and the variable mapping.
src/data_prep.load_data() / ensure_data() helpers that fetch the German Credit dataset from OpenML and cache it under data/ on first use, so the CSVs are no longer redistributed in the repository.
Community/governance files: CONTRIBUTING.md, CODE_OF_CONDUCT.md, .github/SECURITY.md, CODEOWNERS.
pyproject.toml packaging the engine with pinned dependencies, a viz extra for the plotting scripts, and Black/Ruff/mypy/pytest/coverage configuration.
CITATION.cff for software + the accompanying (forthcoming) paper.
tests/ pytest suite covering distances, linear_anm, perception, data_prep, and fairness (with the OpenML fetch mocked — no network access required).
SPDX headers (Copyright (c) 2026 José M. Álvarez / Apache-2.0) on all Python source files.
GitHub Actions workflows (third-party actions pinned to SHA digests): ci, codeql, dep-scan, license-check, pattern-check, cla, stale, release.
.github/dependabot.yml (monthly Python + GitHub Actions updates), issue templates (bug, feature, config) and a PR template.
.github/pattern-check-allowlist.txt for the internal-pattern scan.

Experiment scripts and the linear_anm sanity check now load data via src.data_prep.load_data() instead of reading committed CSVs directly.

The three pre-generated German Credit CSVs (data/*.csv) — regenerated on demand from OpenML.
