I Luk Kim 3c65c72a72 Auto-refresh snapshot when paper backtest end_date exceeds snapshot coverage ... When `fithia2 paper backtest --end <date>` requests a date beyond the snapshot's latest event, automatically runs the pipeline: 1. Filing poller (discover new 8-Ks) 2. Filing fetcher (download exhibits) 3. Event parser (parse events) 4. Feature builder (compute features) 5. Label generator (compute labels) 6. Dataset export (re-generate Parquet snapshot) Staleness check: snapshot is stale if its latest event_date is >14 days before the requested end_date, or if the manifest is >7 days old. If refresh fails, falls back to existing snapshot data gracefully. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		5 months ago
