Overview

Remote readiness checks for a single host, run inside an SSHKit backend.

Every check rescues StandardError at its boundary: the doctor's contract is to report broken environments, not crash on them, and a failed connection can raise anything from Net::SSH errors to Errno and DNS resolution errors.
