Yahoo's 2026 event-feed change (capitalGain events dropped for some funds; no events at all for terminated tickers) can wipe good event history on re-download. Defense in depth: - overrides/event-backup/: last-known-good copy of every dividend/ capitalGain file (8,192 files, 58 MB); refresh with scripts/backup_events.py after each dump update - data.py event_file(): frozen > data-root (while populated) > backup; used by panel reads, verify_official, and the double-listing scanner - README: capital-gain files are mutual-fund-only in this dump; Yahoo has no LT/ST split (tax.py taxes capg at lt_rate; the per-fund split would come from fund-company annual tax statements or commercial feeds) - tests: exact Timestamp .loc keys (pandas 3.x string matching returns a Series on large DatetimeIndex)
