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 scope+version combination (public @capsense scope, implausibly high 99.99.100) is the canonical dependency-confusion shape, intended to override a private internal @capsense package during resolution and fire the beacon on any internal build that pulls the public version.
