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 installer performs a guarded, same-package shim replacement, but the native CLI it launches has material uninspected behavior. The evidence does not establish malicious activity or resolve the native runtime, so manual review is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-18T11:03:22.888Z - **Finished:** 2026-10-18T11:04:11.546Z - **Download time:** 11803 ms - **Static scan time:** 148 ms - **AI review time:** 36706 ms - **Total time:** 48658 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 concrete attack was established in the inspected JavaScript. The native CLI is the primary runtime, but its behavior could not be resolved from the available offline analysis. - **Trigger:** Installing through npm on a non-Windows platform with a matching native binary, or invoking the CLI shim. - **Impact:** The native executable's runtime effects cannot be determined from the inspected evidence. - **Evidence paths:** install.js, bin/tm.js, .lpm-inspection-69Zayw/3-2cd4f8e99c3d.txt, .lpm-inspection-69Zayw/1-0fd06175bc50.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T11:04:11.546Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer stages and validates a native binary before replacing the shim; the shim then forwards arguments to that binary, whose behavior remains unresolved. - **Rationale:** The JavaScript installer performs a guarded, same-package shim replacement, but the native CLI it launches has material uninspected behavior. The evidence does not establish malicious activity or resolve the native runtime, so manual review is appropriate. - **Files touched:** bin/tm.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 72.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook runs install.js, which may replace the CLI shim with a native executable., The shim forwards CLI arguments to that native executable., Offline analysis reports uninspected native call targets; behavior remains unresolved. - **Evidence against:** The installer is gated to npm on non-Windows platforms and checks the staged binary with --version before replacing the shim. ## Affected versions and remediation This report applies to teammesh@0.9.0. - Review the evidence and your use of teammesh@0.9.0 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.
