The quote is visible in the raw CSV but is silently consumed by Excel/LibreOffice as a "text prefix" indicator.useMemokeyed onpayloadsfor performance — no re-computation on unrelated re-renders.react-csv@1.1.2(currently pinned) does not perform any formula neutralization itself; it only applies CSV quoting.status_msg,service,source— any free-text field that a tenant could control.Checklist
