  Probed the company's primary corporate domain (usnc.com) and the one reachable
  name-adjacent domain (ultrasafenuclear.com, ownership unverified). usnc.com publishes no
  address record, so there is no host to test for TLS/HSTS; its mail plane is still
  configured on the Microsoft 365 US Government cloud with a quarantine DMARC policy, which
  is the clearest single signal that the entity was wound down rather than migrated.
