--- _-= Per source details.

The receiver ID in the URL is left as a `<your-id>` placeholder, so the beacon URL is not fully configured, but the postinstall hook still fires on `npm install` and issues an outbound request carrying host identification to a third-party collector. The package version tag also self-labels as `security-research`, but the shipped behavior — an automatic install-time beacon of host identity to an external collector — matches dependency-confusion / reconnaissance beacon shape rather than a benign library.
