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 shipped source of amplitude-experiment@55.0.0 itself is an inert stub, so the manifest line is the entire delivery mechanism. The dependency key matching the package's own name mirrors a dependency-confusion shape against the legitimate `amplitude-experiment` name, and the implausibly high version (55.0.0) is consistent with a resolution-winning squat.\n\nAny computer that has this package installed or running should be considered fully compromised.
