release.py was 2,804 lines, 2,076 of them the frozen legacy author dict. The map and its resolver now live in scripts/releases/: authors.py holds the directory loader, the merged AUTHOR_MAP and resolve_author, and authors_legacy.py holds only the frozen LEGACY_AUTHOR_MAP literal (same 1,895 entries, same order). release.py drops to 707 lines. The contributor-check job and audit_pr_attribution.py grep the legacy file for quoted emails, so both now read authors_legacy.py. The importers (contributor_audit.py, add_contributor.py), contributors/README and the tests read the defining modules. No behaviour change.
