provenance


This audit was generated by running stackpeek against https://resend.com from a public IP, using only HTTP GET and standard browser headers. The findings compare the observed HTML against the policy discovery results (no policy document was located) using the public methodology. Re-scans append new findings at new permalinks and never overwrite the historical record.
