AI Security Review
scanned 4d ago · by lpm-firewall-aiThe manifest has no install lifecycle hooks, and the flagged credential flow refuses API-key authentication rather than collecting or forwarding that key. The new scheduled closeout behavior requires an explicit CLI install command, so the reviewed findings do not show malicious default behavior.
Static reason
No blocking static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Closeout runs only when its CLI command or explicitly installed scheduled job is invoked.
Impact
No unauthorized credential transfer, install-time action, or default persistence was identified.
Mechanism
The optional closeout feature selects eligible quiet sessions, then invokes Claude in a constrained, budget-limited subprocess. Credential proof uses account identifiers and refuses API-key authentication.
AI rationale
The manifest has no install lifecycle hooks, and the flagged credential flow refuses API-key authentication rather than collecting or forwarding that key. The new scheduled closeout behavior requires an explicit CLI install command, so the reviewed findings do not show malicious default behavior.

Decision evidence
public snapshotAI called this Clean at 87.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest has no install, preinstall, or postinstall lifecycle scripts.
- The Anthropic key check refuses confidential-session identity proof when API-key or cloud-provider authentication is in use.
- The closeout sweep and LaunchAgent installer run only through explicit CLI subcommands.
- Closeout state is stored under the user's ~/.cortex/closeout directory.
Evidence against
- The opt-in closeout feature can periodically resume eligible Claude sessions and use the user's account.
- The CLI has a SessionStart path that can heal a confidential guard into Claude settings.
