## 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:** 0.1.33
- **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 behavior matches the package's stated purpose: it stages its bundled launchers and platform binaries in a package-local directory. The TUI performs a background version check, but the inspected source shows no collection or transmission of host, user, project, or credential data.

## Latest scan

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 identified. The postinstall hook sets up the package's own launchers and binaries; a TUI startup update check queries package metadata.

- **Trigger:** npm postinstall runs setup; launching the TUI starts a background daily update check.

- **Impact:** The observed setup prepares the terminal manager for use, and the update check retrieves version metadata. No host or user data collection was identified in the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T12:54:39.135Z

### AI review details

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

- **Mechanism:** Setup copies bundled scripts and platform-specific binaries into dist/. The update check queries the npm package version, with Homebrew metadata checks for brew installations.

- **Rationale:** The postinstall behavior matches the package's stated purpose: it stages its bundled launchers and platform binaries in a package-local directory. The TUI performs a background version check, but the inspected source shows no collection or transmission of host, user, project, or credential data.

- **Files touched:** dist/

- **Network endpoints:** npm registry (via \`npm view rakumux version\`), Homebrew metadata (via \`brew info rakumux\`)

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package describes itself as a terminal session manager and declares command-line entry points for its TUI, local launcher, MCP server, and API server., The postinstall hook runs install.js, which copies the package's launcher scripts and platform-specific prebuilt binaries into its package-local dist directory., The automatic daily update check runs only when launching the TUI; the updater queries npm for the rakumux version, and the script also supports checking Homebrew metadata., The inspected JavaScript and shell code shows no install-time network request, credential collection, or unrelated account action.

- **Evidence against:** The postinstall hook runs automatically and replaces the package-local dist directory with copied assets., The shipped native executables could not be semantically inspected by the offline analyzer; their presence is consistent with the package's documented command-line and daemon purpose.
