Divergence review — the generated cross-method ledger

Everything in this folder except this README is generated — build_divergence_index.py re-tabulates the curated single-winner STAR library under RCV-IRV, Ranked Robin, and Approval on every commit (wired into the pre-commit hook) and rewrites the ledger. Don't hand-edit; edit the source elections instead.

• INDEX.md — the ledger: every election where at least one method disagrees with STAR, with winners per method.
• divergence.csv — the same table, machine-readable.
• cases/ — one generated teaching page per divergent election.
