## 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:** 0.42.0
- **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 install hook conditionally stages and checks the package's own CLI binary, while the command shim forwards user-supplied arguments to that binary. The available source shows no unrelated collection or unsolicited account action, so the lifecycle and binary findings are consistent with the package's stated purpose.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified; this package installs and launches its TeamMesh CLI.

- **Trigger:** The postinstall hook runs during installation; the CLI runs when invoked.

- **Impact:** No harmful collection, unrelated network contact, or unsolicited account action was established from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T14:15:32.357Z

### AI review details

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

- **Mechanism:** On supported npm installs, the hook stages a bundled platform binary, checks its version command, and swaps it into the CLI path. The shim forwards user arguments to that binary.

- **Rationale:** The install hook conditionally stages and checks the package's own CLI binary, while the command shim forwards user-supplied arguments to that binary. The available source shows no unrelated collection or unsolicited account action, so the lifecycle and binary findings are consistent with the package's stated purpose.

- **Files touched:** install.js, bin/tm.js, native/\<platform\>-\<arch\>/tm

### Review decision

- **Verdict:** Clean

- **Confidence:** 84.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall script only proceeds on non-Windows npm installs and only when a platform binary exists., The install script stages the bundled binary, checks it with --version, and replaces the CLI shim; failures remove the staged file., The CLI shim launches the matching bundled native binary with the user's supplied arguments.

- **Evidence against:** The package has a postinstall hook that runs bundled native code., The native executable behavior is not fully inspectable from the available analysis.
