## 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:** 0.20.0
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

Static inspection confirms that installation and CLI use execute shipped native binaries, but available offline analysis leaves multiple binaries unresolved. No concrete malicious behavior is established, so manual review is appropriate.

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:** The install hook executes a shipped platform binary, and the CLI later forwards commands to it. Its behavior remains unresolved from the available offline analysis, so no specific attack is confirmed.

- **Trigger:** Package installation on supported npm platforms, followed by invoking the tm command.

- **Impact:** The native binary can run during installation and normal CLI use, but the inspected evidence does not establish what it does.

- **Evidence paths:** .lpm-inspection-6Ltnzc/0-e7bd49be9db1.txt, .lpm-inspection-6Ltnzc/1-6afbf09857c5.txt, .lpm-inspection-6Ltnzc/5-f564d030683f.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T22:00:35.102Z

### AI review details

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

- **Mechanism:** The installer probes a native binary with --version and replaces the JavaScript shim if it runs; the shim forwards later arguments to that binary.

- **Rationale:** Static inspection confirms that installation and CLI use execute shipped native binaries, but available offline analysis leaves multiple binaries unresolved. No concrete malicious behavior is established, so manual review is appropriate.

- **Files touched:** install.js, bin/tm.js, native/linux-x64/tm, native/linux-arm64/tm, native/win32-arm64/tm.exe

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 78.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The postinstall hook runs install.js., The installer executes the selected native binary with --version before replacing the CLI shim., The CLI shim passes user arguments to the native binary., Offline inspection could not resolve the Linux x64 and Linux ARM64 binaries; Windows ARM64 inspection also failed.
