The state of GitHub Actions hygiene in top open-source repos

Generated 2026-08-02 by gha-doctor 0.45.0 via scripts/state-of-actions.sh — static workflow lint of the 250 most-starred repos on GitHub, fetched through the contents API (no clones). Numbers change as repos change; regenerate any time. Runtime sequel: the CI waste ledger — what these repos’ runs actually burned.
