## 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:** 0.26.0
- **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 reviewed JavaScript establishes that installation and normal CLI use execute the shipped native binary. Because the available analyses cannot resolve that executable's behavior, the package's runtime cannot be classified as clean or malicious from this inspection.

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:** Installation can run a platform-specific native executable, and CLI use delegates to that executable. Its behavior remains unresolved, so no specific attack is confirmed.

- **Trigger:** An eligible npm postinstall or invocation of the tm command.

- **Impact:** The native executable's effects cannot be determined from the available analysis.

- **Evidence paths:** .lpm-inspection-3Gfnq0/0-4c2801a3972b.txt, .lpm-inspection-3Gfnq0/1-c22bce753718.txt, .lpm-inspection-3Gfnq0/2-bc01fca8f55d.txt, .lpm-inspection-3Gfnq0/3-8552dc221bd8.txt, .lpm-inspection-3Gfnq0/4-e2f52946bd59.txt, .lpm-inspection-3Gfnq0/5-c5fa9332ee41.txt

### AI review details

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

- **Mechanism:** The hook runs the native executable for a version check and may replace the JavaScript shim; the shim forwards command arguments to the native executable.

- **Rationale:** The reviewed JavaScript establishes that installation and normal CLI use execute the shipped native binary. Because the available analyses cannot resolve that executable's behavior, the package's runtime cannot be classified as clean or malicious from this inspection.

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

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 96.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest runs install.js after installation; on eligible systems, the hook stages and runs the native binary before replacing the CLI shim., The CLI shim passes its arguments to the platform-specific native executable., Offline analyses leave the native behavior unresolved: several formats are unsupported, and the Windows x64 analysis is incomplete.
