AI Security Review
scanned 4h ago · by lpm-firewall-aiThe inspected postinstall behavior is consistent with repairing a native dependency, and the inspected credential operations use local keychain storage. The required clean citation coverage exceeds the citation limit, so the package cannot be cleared by this review.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Package installation triggers the native binary repair hook; other inspected features require runtime or explicit setup actions.
Impact
The inspected behavior does not establish unauthorized access or data transfer; broader package behavior remains unresolved.
Mechanism
The hook tests the installed native binary and can fetch a matching release artifact. The inspected credential helpers use the local keychain.
AI rationale
The inspected postinstall behavior is consistent with repairing a native dependency, and the inspected credential operations use local keychain storage. The required clean citation coverage exceeds the citation limit, so the package cannot be cleared by this review.

Decision evidence
public snapshotAI called this Manual Review at 64.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The postinstall hook runs a script that repairs the better-sqlite3 native binary.
- The repair script builds a version and platform specific download URL for the better-sqlite3 release on GitHub.
- The credential helper reads a named service and account from the local macOS keychain; another helper writes credentials to that keychain.
