Solid steps show periods confirmed by the store’s change-only price history and completed crawl record: if the price had changed at a check, another point would appear. Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
