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 inspected JavaScript shows an npm postinstall replacing the CLI wrapper with a bundled native executable, and the wrapper launches that executable. Offline analysis could not resolve the behavior of most binaries and was incomplete for the supported Windows binary, so the package’s core runtime behavior remains unresolved without evidence sufficient to classify it as malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-24T03:13:36.561Z - **Finished:** 2026-10-24T03:14:11.739Z - **Download time:** 2853 ms - **Static scan time:** 163 ms - **AI review time:** 32162 ms - **Total time:** 35178 ms 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 attack is established by the inspected JavaScript source. The package dispatches its CLI to bundled native executables whose behavior remains materially unresolved. - **Trigger:** Installing through npm can replace the JavaScript command wrapper with a native executable; running tm invokes the platform-matched executable. - **Impact:** The native CLI’s effects cannot be determined from the available offline analysis, so its behavior remains unresolved. - **Evidence paths:** 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, .lpm-inspection-iVJ8yU/0-ab6a32640c95.txt, .lpm-inspection-iVJ8yU/1-343f222b423e.txt, .lpm-inspection-iVJ8yU/2-30214bd5e05e.txt, .lpm-inspection-iVJ8yU/3-959d7837fb41.txt, .lpm-inspection-iVJ8yU/4-01d3acf96ebe.txt, .lpm-inspection-iVJ8yU/5-48c9dc57c297.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-24T03:14:11.739Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook copies and stages a native binary, then replaces the wrapper. The wrapper launches the bundled binary with the command-line arguments. - **Rationale:** The inspected JavaScript shows an npm postinstall replacing the CLI wrapper with a bundled native executable, and the wrapper launches that executable. Offline analysis could not resolve the behavior of most binaries and was incomplete for the supported Windows binary, so the package’s core runtime behavior remains unresolved without evidence sufficient to classify it as malicious. - **Files touched:** 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:** 90.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json defines an npm postinstall hook that runs install.js and exposes bin/tm.js as the tm command., On supported npm platforms, install.js stages the matching native executable and replaces bin/tm.js after checking that it runs., The CLI wrapper selects a platform-specific native executable and launches it with the supplied arguments., Offline analysis could not inspect most shipped native executables; the Windows x64 analysis also leaves call targets uninspected., The inspected source establishes native executable dispatch but does not establish malicious behavior. ## Affected versions and remediation This report applies to teammesh@0.28.2. - Review the evidence and your use of teammesh@0.28.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** install.js - **Public source:** [View source]() On supported npm platforms, install.js stages the matching native executable and replaces bin/tm.js after checking that it runs. Public source snippet (untrusted): ```javascript if (process.platform === "win32") process.exit(0); if (!(process.env.npm[redacted] ?? "").startsWith("npm/")) process.exit(0); const binary = path.join(__dirname, "native", `${process.platform}-${process.arch}`, "tm"); 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); ``` ### 11.
