If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

Any installer whose tooling resolves this name — including unrelated developers and CI systems — leaks public IP, DNS resolver identity, hostname-derived callback id, and install timing to the OAST endpoint without consent.
