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.

The dependency key equals the package's own name, producing a dependency-confusion shape in which resolution is forced through the off-registry host.
