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

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 0.2.385
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The inspected JavaScript excerpts do not establish an attack, and the static signals alone do not support blocking. The native CLI remains materially unresolved because its bounded source analysis cannot establish reachability or exclude other behavior, so manual review is appropriate.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 75.0%

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 attack was confirmed in the inspected excerpts. The packaged native CLI remains unresolved because the available analysis samples embedded source without establishing reachability or ruling out other native behavior.

- **Trigger:** Launching the packaged CLI is the relevant potential trigger; its native activation path is not fully resolved by the available analysis.

- **Impact:** Unresolved; the inspected evidence does not confirm harmful effects.

- **Evidence paths:** bin/ara, bin/runtime/srt/sandbox-runtime.mjs, .lpm-inspection-1RhyQ1/0-bbdc891be54a.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T08:01:21.466Z

### AI review details

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

- **Mechanism:** The extracted native-source candidates include local agent-configuration inspection, but the analysis does not establish whether those candidates are loaded or what other native code does.

- **Rationale:** The inspected JavaScript excerpts do not establish an attack, and the static signals alone do not support blocking. The native CLI remains materially unresolved because its bounded source analysis cannot establish reachability or exclude other behavior, so manual review is appropriate.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 75.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest identifies this package as the darwin-x64 Reason CLI binary., The required runtime location contains sandbox path-filtering logic and names project directories; it does not establish a write there., The offline analysis extracts a candidate Cursor configuration reader and identifies Reason service URLs, but does not establish that this code is reachable., The packaged Mach-O executable is 78 MB; its analysis uses bounded embedded-source windows and cannot rule out other native behavior.

- **Evidence against:** The inspected excerpts do not establish credential transfer, unconsented agent configuration changes, or another concrete attack., The extracted Cursor code checks for an existing configuration and handles invalid JSON by refusing to overwrite it.

## Affected versions and remediation
