Lookout

New .gov subdomains as they appear in public Certificate Transparency logs — flagged when a name looks like a preview/staging/infra host or mimics another agency’s function. Existence-only: we note that a cert exists; we never connect to the host. Watching 911 known subdomains, plus new public repositories under watched federal GitHub orgs.
