## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.1.6
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection found no lifecycle hooks and no concrete attack behavior. Network activity is tied to the package’s licensing, rule-feed, and gated usage functions.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 95.0%
- **Started:** 2026-10-24T12:31:39.842Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The package provides a command-line scanner with license checks and limited vendor telemetry.

- **Trigger:** A user invokes the CLI or its MCP server.

- **Impact:** No unconsented credential disclosure, destructive behavior, or other concrete attack effect was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-24T12:32:31.735Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The CLI scans requested files; license keys are used with licensing and vendor rule services, while usage events are limited and gated to interactive sessions with opt-outs.

- **Rationale:** Source inspection found no lifecycle hooks and no concrete attack behavior. Network activity is tied to the package’s licensing, rule-feed, and gated usage functions.

- **Files touched:** cli.js, license.js

- **Network endpoints:** api.polar.sh, getreadystack.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 95.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json exposes cli.js as the command and contains no lifecycle hook entries., cli.js loads the license helper and merges returned rules into the scanner; the CLI otherwise scans files and renders findings., License keys come from an explicit argument, environment variable, or saved state and are sent to Polar for validation or to the vendor rules feed., Usage events contain limited product-use fields and are gated to interactive use; environment opt-outs and CI suppress them.

- **Evidence against:** The inspected network behavior supports package licensing, rule delivery, and limited vendor telemetry; it does not establish unrelated credential disclosure or other attack behavior.
