Cert, Domain and DNS Guard

Watches up to 10 domains: certificates logged in CT (crt.sh, exact name), registration expiry via RDAP, DNS via Cloudflare DoH. Emails your AgentMail inbox and up to 25 addresses once per finding: a new logged certificate, the domain expiring within 30/14/7 or 60/30/7 days, a certificate from an issuer you did not pin, a DNS record off its pin or changed (two checks in a row). Timeouts are unknown, never findings. Public on chain.
