AI Security Review
scanned 1mo ago · by lpm-firewall-aiStatic inspection found no lifecycle execution, self-dependency, hidden payload, or unconsented credential or control-surface action. Available capabilities are exposed through factories or enabled settings.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
No malicious trigger was identified.
Impact
No malicious impact was identified.
Mechanism
No malicious mechanism was identified.
AI rationale
Static inspection found no lifecycle execution, self-dependency, hidden payload, or unconsented credential or control-surface action. Available capabilities are exposed through factories or enabled settings.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- Package metadata defines development scripts and no install lifecycle hook.
- The main module exposes controller factories rather than invoking one at import time.
- Browser creation returns unless the supplied settings explicitly enable it.
