The bot snapshots metrics every cycle (~1,300 rows/day, 74K rows in 57 days) but only the last snapshot of each past UTC day is ever read back. Prune past days to their daily close at 00:10 UTC; today's rows are kept intact for /api/summary. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# (~1,300/day); only the close of past days is read back (DISTINCT ON in

# feeds /api/summary and the close is still evolving.
