No install-time lifecycle execution, no network I/O, no credential or environment reads, no filesystem writes outside the package directory, and no obfuscated or dynamically fetched code were observed. The package exposes no behavior that affects an installer's machine, credentials, or dependency resolution.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
