Independent LPM AI assessment
SuspiciousIndependent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.
Automatic install-time reporting of hostname and project paths creates a concrete metadata disclosure risk, though the recipient is restricted to localhost. This supports a warning rather than a block because no external exfiltration or other attack behavior is established.

- Importing the main entrypoint also attempts to fire the beacon.
- The destination is fixed at 127.0.0.1; no external endpoint or credential collection is shown.
