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 a postinstall native-binary check and a launcher that delegates to native code. Analysis of the Windows x64 binary is incomplete, leaving material runtime behavior unresolved; manual review is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-18T17:14:08.891Z - **Finished:** 2026-10-18T17:14:58.161Z - **Download time:** 4369 ms - **Static scan time:** 158 ms - **AI review time:** 44743 ms - **Total time:** 49270 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 was identified in the inspected JavaScript source. The package installs and launches native executables whose behavior remains materially unresolved. - **Trigger:** Package installation runs the postinstall hook; invoking the CLI launches the platform-specific native executable. - **Impact:** The native executable’s runtime effects cannot be determined from the available analysis, so malicious behavior is neither confirmed nor ruled out. - **Evidence paths:** .lpm-inspection-bXHD6G/3-ca58360846db.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T17:14:58.161Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer executes a staged binary to check its version and may replace the JavaScript shim with it. The launcher forwards CLI arguments to the native binary. - **Rationale:** The inspected JavaScript shows a postinstall native-binary check and a launcher that delegates to native code. Analysis of the Windows x64 binary is incomplete, leaving material runtime behavior unresolved; manual review is appropriate. - **Files touched:** install.js, bin/tm.js, native/win32-x64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 83.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook runs install.js, which executes the staged native binary during installation., The CLI launcher passes its arguments to a platform-specific native binary., The inspected native analysis reports uninspected call targets and cannot establish the binary’s behavior. - **Evidence against:** The installer checks the staged binary’s version before replacing the JavaScript shim; no attack behavior is established by the inspected source. ## Affected versions and remediation This report applies to teammesh@0.13.0. - Review the evidence and your use of teammesh@0.13.0 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.
