Provenance

Every event carries a provenance block: source, first_seen_at, last_seen_at (last cron run on which the source still listed it), source_checked_at (when we last completed a read of that source), still_listed / delisted_since / cancelled_at_source, price_as_of, and a summary confidence (high = re-confirmed within ~30 h, medium = within a week or the source is dormant, low = older, removed or cancelled at the source). Treat low as "verify before relying on it".
