What does this page help me record?
It provides a reusable record for retirement guide for Oopbuy Spreadsheet rows that explains when to archive a stale source, preserve its evidence, and open a fresh replacement check, without claiming current inventory, price, quality, or delivery outcomes.
What should be checked on the live source?
Open the Oopbuy Spreadsheet resource and confirm the current wording, source path, and evidence before acting.
What if the source has changed?
Keep the previous observation, add the new observation with a date, and explain the decision instead of overwriting history.
