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 source shows that the CLI runs shipped native executables, but offline analysis leaves their behavior unresolved. This does not establish malicious behavior; manual review is appropriate because the native program is the active CLI implementation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-16T15:38:16.906Z - **Finished:** 2026-10-16T15:39:17.805Z - **Download time:** 1022 ms - **Static scan time:** 35 ms - **AI review time:** 59842 ms - **Total time:** 60899 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:** The package activates native executables through its CLI and may install one during postinstall. Their behavior remains unresolved after offline inspection, so no specific attack is confirmed. - **Trigger:** Installing the package with lifecycle scripts enabled or invoking the \`tm\` CLI. - **Impact:** The native program’s effects cannot be determined from the inspected source and available offline analysis. - **Evidence paths:** .lpm-inspection-arbfc5/1-95ebfb4d7cf4.txt, .lpm-inspection-arbfc5/3-281211c34d69.txt, .lpm-inspection-arbfc5/0-2d82716e4d11.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-16T15:39:17.805Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall may replace the CLI shim with a native executable, and the shim launches the platform-specific executable with the supplied arguments. - **Rationale:** The source shows that the CLI runs shipped native executables, but offline analysis leaves their behavior unresolved. This does not establish malicious behavior; manual review is appropriate because the native program is the active CLI implementation. - **Files touched:** install.js, bin/tm.js, native/linux-arm64/tm, native/win32-x64/tm.exe, native/win32-arm64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 95.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package runs \`install.js\` during postinstall., The installer may replace the CLI shim with a native executable after checking that it runs., The CLI passes its arguments to the platform-specific native executable., Offline analysis could not inspect the Linux ARM64 executable’s behavior., The Windows x64 analysis leaves native call targets uninspected., The Windows ARM64 executable’s inspection failed. - **Evidence against:** The installer exits on Windows and when npm is not the package manager., The installer removes the staged file if the native executable check or replacement fails. ## Affected versions and remediation This report applies to teammesh@0.1.2. - Review the evidence and your use of teammesh@0.1.2 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.
