## 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:** 0.2.402
- **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 manifest has no install hook, and the inspected source does not establish an attack. Several packaged native executables remain materially unresolved, so the package cannot be cleared from static source inspection alone.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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 is confirmed. The package contains executable native artifacts whose behavior remains unresolved, and embedded source includes a Cursor configuration-writing helper whose activation was not established.

- **Trigger:** Unknown; the available analysis does not establish when the native code or configuration helper runs.

- **Impact:** Potential effects cannot be determined from the inspected evidence.

- **Evidence paths:** .lpm-inspection-edIasV/0-5eb2e06f53be.txt, .lpm-inspection-edIasV/1-259d1a52b01a.txt, .lpm-inspection-edIasV/2-ecebee023697.txt, .lpm-inspection-edIasV/3-7873d1f8b310.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T17:56:12.217Z

### AI review details

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

- **Mechanism:** The offline executable analysis covers bounded embedded-source windows only; other native artifacts are unsupported, and the helper's callers were not resolved.

- **Rationale:** The manifest has no install hook, and the inspected source does not establish an attack. Several packaged native executables remain materially unresolved, so the package cannot be cleared from static source inspection alone.

- **Files touched:** bin/reason, bin/Background/Reason.app/Contents/MacOS/ReasonBackgroundIdentity, bin/Background/Reason.app/Contents/Helpers/ReasonPermissionTile, bin/libreason\_device\_keychain.dylib

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 91.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The bundled executable is a 72.9 MB Mach-O, and its embedded source analysis warns that bounded excerpts do not establish loader reachability or rule out other behavior., Three additional packaged Mach-O artifacts have no supported executable analysis, leaving their behavior unresolved., The inspected runtime location lists configuration paths and exclusions, but does not establish an attack., The embedded executable includes a helper that writes a Cursor MCP configuration file; its activation and callers are not resolved by the available excerpts.

- **Evidence against:** package.json has no lifecycle script and identifies this as a macOS ARM64 native-binary package., The inspected source excerpts do not establish malicious behavior or an active attack.

## Affected versions and remediation
