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 package name `@0xlr/prisma-client-js` impersonates the legitimate prisma-client-js / @prisma/client packages, and the 999.0.0 version is the canonical dependency-confusion override pattern; the package.json description self-identifies as a 'Placeholder reservation' for that namespace.
