## 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:** 0.5.0
- **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 source shows a native CLI installation and launch path, while the available binary analysis is incomplete or unsupported. Because the native behavior remains materially unresolved, manual review is appropriate; the inspected evidence does not establish a specific attack.

## Security analysis

### Published attack-surface review

- **Summary:** The package installs and launches platform-specific native CLI binaries. Their behavior could not be resolved from the available analysis, so a concrete attack was not established.

- **Trigger:** Package installation may replace the launcher on supported npm platforms; running tm starts the selected native binary.

- **Impact:** The native program's effects, including the purpose of its api.teammesh.io reference, remain undetermined.

- **Evidence paths:** install.js, bin/tm.js, .lpm-inspection-XIuhDn/3-7deff70dd7bb.txt, .lpm-inspection-XIuhDn/5-7bbf49498dd1.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T02:37:27.884Z

### AI review details

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

- **Mechanism:** The installer copies a native binary over the JavaScript shim after a version check, and the shim otherwise spawns that binary.

- **Rationale:** The JavaScript source shows a native CLI installation and launch path, while the available binary analysis is incomplete or unsupported. Because the native behavior remains materially unresolved, manual review is appropriate; the inspected evidence does not establish a specific attack.

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

- **Network endpoints:** api.teammesh.io

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 78.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest runs install.js during postinstall and ships the CLI and native binaries., On supported npm installs, install.js replaces the JavaScript launcher with the matching native binary after checking its version., The launcher runs the platform binary with the caller's arguments., The available native analyses leave behavior unresolved; the Windows analysis notes uninspected call targets, and the Linux binary is unrecognized., The Windows binary analysis contains a reference to api.teammesh.io, but does not establish when or how it is contacted.

### 9. Low: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 78.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/teammesh@0.5.0/package.json>)

Public source snippet (untrusted):

```json
"scripts": {
    "postinstall": "node install.js"
  },
  "files": [
    "bin",

- **Confidence:** 78.0%
- **Path:** install.js
- **Public source:** [View source](<https://unpkg.com/teammesh@0.5.0/install.js>)

On supported npm installs, install.js replaces the JavaScript launcher with the matching native binary after checking its version.

Public source snippet (untrusted):

```javascript
if (!fs.existsSync(binary)) process.exit(0);

const shim = path.join(__dirname, "bin", "tm.js");
const staged = `${shim}.native`;
try {
  fs.copyFileSync(binary, staged);
  fs.chmodSync(staged, 0o755);
  // Only swap in a binary that actually runs here.
  execFileSync(staged, ["--version"], { stdio: "ignore" });
  fs.renameSync(staged, shim);
} catch {
  fs.rmSync(staged, { force: true });
}
```

### 11. Low: Ai Review Evidence

- **Confidence:** 78.0%
- **Path:** bin/tm.js
- **Public source:** [View source](<https://unpkg.com/teammesh@0.5.0/bin/tm.js>)

The launcher runs the platform binary with the caller's arguments.

Public source snippet (untrusted):

```javascript
process.exit(1);
}

const result = spawnSync(binary, process.argv.slice(2), { stdio: "inherit" });
if (result.error) {
  console.error(`tm: ${result.error.message}`);
  process.e
```
