## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 0.1.38
- **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 postinstall hook performs local setup by copying the package’s scripts and bundled binaries into dist/. The visible network activity is an update-version lookup; the available offline analysis could not establish the native binaries’ internal behavior, but their role matches the package’s stated purpose and launchers.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified in the inspected package source; the postinstall hook sets up the CLI’s bundled assets.

- **Trigger:** npm postinstall; the update check runs when the TUI starts or when the user requests an update check.

- **Impact:** Local CLI setup and an update-version lookup; no inspected code sends host, user, project, or credential data.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T07:12:32.467Z

### AI review details

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

- **Mechanism:** Postinstall copies scripts and platform binaries into dist/. The update check queries the Rakumux package version through npm.

- **Rationale:** The postinstall hook performs local setup by copying the package’s scripts and bundled binaries into dist/. The visible network activity is an update-version lookup; the available offline analysis could not establish the native binaries’ internal behavior, but their role matches the package’s stated purpose and launchers.

- **Files touched:** dist/

- **Network endpoints:** npm registry (via npm view rakumux version)

### Review decision

- **Verdict:** Clean

- **Confidence:** 87.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest describes Rakumux as a terminal session manager and routes its CLI commands through launcher scripts., The postinstall hook recreates dist/ and copies the package’s scripts and platform binaries there., The launcher’s update check queries the latest Rakumux version through npm; it does not send package, project, or user data in the inspected code.

- **Evidence against:** The package includes native executables whose behavior could not be established from the available offline analysis., The visible network activity is consistent with checking for package updates.
