## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 0.1.32
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The runtime updater launches an opaque script automatically when the launcher starts, leaving meaningful execution risk unresolved. The inspected source does not prove malicious behavior, so this warrants a warning rather than a publish block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 78.0%
- **Started:** 2026-10-17T00:13:01.256Z

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 concrete attack is established, but the launcher executes an opaque update script in a detached process.

- **Trigger:** A user launches the agent through the launcher.

- **Impact:** The child process can execute further code, but its effects are unresolved from the inspected source.

- **Evidence paths:** dist/launcher.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T00:17:04.550Z

### AI review details

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

- **Mechanism:** The launcher checks for a newer version and passes an embedded script to a child Node process; obfuscation prevents verifying that script’s behavior.

- **Rationale:** The runtime updater launches an opaque script automatically when the launcher starts, leaving meaningful execution risk unresolved. The inspected source does not prove malicious behavior, so this warrants a warning rather than a publish block.

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 78.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** On launcher startup, the package checks for an update and starts a detached Node process with an embedded script; that script’s behavior is obscured., The publish script runs an obfuscator, and the shipped launcher contains encoded strings decoded at runtime, limiting verification of the update script., The manifest defines prepublishOnly but no preinstall, install, or postinstall hook.

- **Evidence against:** The updater runs when the launcher is invoked, rather than through an install hook., The inspected source does not establish that the embedded script downloads or executes a malicious payload.

## Affected versions and remediation
