## 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:** 0.12.0
- **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.

The JavaScript shows a platform-specific installer and CLI launcher, but both execute native binaries whose behavior the available analyses could not resolve. That leaves a material runtime question, so the package needs manual review rather than a clean or malicious verdict.

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 in the inspected JavaScript, but the package launches opaque native executables as its CLI and from its install hook, leaving their behavior unresolved.

- **Trigger:** Installing with npm on a non-Windows platform runs the matching executable with --version; invoking tm runs the matching executable on supported platforms.

- **Impact:** The native program can run during installation and normal CLI use, but its effects could not be established from the available offline analyses.

- **Evidence paths:** native/linux-x64/tm, .lpm-inspection-BKejxW/5-85eb2f89915e.txt, native/linux-arm64/tm, .lpm-inspection-BKejxW/1-7429d5bc7b55.txt, native/darwin-x64/tm, .lpm-inspection-BKejxW/2-bd9cacd1886a.txt, native/darwin-arm64/tm, .lpm-inspection-BKejxW/4-73b2cad8b82a.txt, native/win32-x64/tm.exe, .lpm-inspection-BKejxW/3-01d90a13e4aa.txt, native/win32-arm64/tm.exe, .lpm-inspection-BKejxW/0-31eb3d56646f.txt

### AI review details

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

- **Mechanism:** The install hook tests and replaces the JavaScript shim with a native executable, while the shim forwards CLI arguments to that executable.

- **Rationale:** The JavaScript shows a platform-specific installer and CLI launcher, but both execute native binaries whose behavior the available analyses could not resolve. That leaves a material runtime question, so the package needs manual review rather than a clean or malicious verdict.

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

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 88.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json runs install.js after installation., The CLI forwards user arguments to a platform-specific native executable., On npm installs outside Windows, install.js runs the matching executable with --version before replacing the CLI shim., The supplied offline analyses could not resolve the behavior of the native executables, which the install hook and CLI run.
