## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 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:** 0.1.37
- **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.

The scanner’s obfuscation hints are supported by the source, but the inspected behavior did not establish malicious activity. The package has no install-time lifecycle hook, and its reviewed network behavior is portal authentication and failure reporting.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 76.0%

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 confirmed attack surface was identified in the inspected source. The package provides a portal client and feedback reporting, but the reviewed excerpts do not show credential forwarding to an unrelated recipient or malicious execution.

- **Trigger:** The CLI runs when invoked; feedback reporting is triggered by a qualifying portal failure or an explicit feedback action.

- **Impact:** The reviewed behavior supports normal portal authentication and operational feedback; no concrete attack impact was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T08:08:46.141Z

### AI review details

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

- **Mechanism:** The launcher uses configured portal settings, and the portal client sends its token to that portal. Feedback code posts a supplied report payload.

- **Rationale:** The scanner’s obfuscation hints are supported by the source, but the inspected behavior did not establish malicious activity. The package has no install-time lifecycle hook, and its reviewed network behavior is portal authentication and failure reporting.

### Review decision

- **Verdict:** Clean

- **Confidence:** 76.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for AI clean decision:** package.json defines a publish-time build hook, with no install-time lifecycle hook., dist/launcher.js takes the portal URL from runtime configuration; dist/portalClient.js attaches the token to requests for that configured portal., dist/feedback.js sends supplied feedback data by POST; source ties automatic reports to selected failure responses.

- **Evidence against:** dist/index.js and the flagged files are heavily obfuscated, which makes their behavior harder to audit, but the inspected excerpts did not establish a malicious payload or attack.
