# Once Books security contact — RFC 9116. # # `/security.txt` 301s here (see public/_redirects), so both the well-known # location scanners check and the bare path people type resolve to this file. # # `Expires` is required by the RFC and is what makes a stale file detectable: # a researcher reading an expired contact has no reason to trust it. Renew it # in place. `scripts/security-txt.test.mjs` fails once this date is inside 30 # days, so the renewal lands before the file goes stale rather than after.
