Greg Pomerantz bb8e39605e Event-history protection: backup dir, empty-download fallback, docs
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)
