## 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:** 0.2.394
- **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 lifecycle hook, and the inspected runtime location does not prove harmful agent configuration behavior. The required executable analysis is bounded and leaves activation and credential handling unresolved, so manual review is appropriate.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 92.0%

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. Bounded embedded-source analysis of the shipped executable includes code that reads provider API-key values, but its activation and any transfer recipient could not be established.

- **Trigger:** The executable’s activating path is unresolved in the available static analysis.

- **Impact:** Whether the values leave the machine or are used only for a local feature remains unresolved.

- **Evidence paths:** .lpm-inspection-ehPxYq/0-46ddd067a712.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T10:47:56.422Z

### AI review details

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

- **Mechanism:** A helper in an embedded-source candidate collects API-key values from environment variables; the inspected excerpt does not establish a send operation.

- **Rationale:** The manifest has no lifecycle hook, and the inspected runtime location does not prove harmful agent configuration behavior. The required executable analysis is bounded and leaves activation and credential handling unresolved, so manual review is appropriate.

- **Files touched:** bin/reason.exe

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 92.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json identifies a Windows ARM64 package containing platform binaries and defines no lifecycle hook., The required runtime location defines paths related to MCP and Claude configuration, but this excerpt does not establish a configuration write or its caller., The executable’s bounded embedded-source analysis contains a helper that reads provider API-key values; the helper’s activation and recipient are not established., The host analysis explicitly says its bounded source windows cannot prove executable reachability or exclude other native behavior.

- **Evidence against:** No package install hook or confirmed credential transfer appears in the inspected evidence., The inspected runtime excerpt alone does not establish an agent configuration mutation.

## Affected versions and remediation
