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 and launcher show ordinary binary setup and command forwarding, but the native CLI is the package’s primary runtime and its behavior remains materially unresolved. Manual review is needed to assess those binaries. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-19T11:58:16.334Z - **Finished:** 2026-10-19T11:59:32.238Z - **Download time:** 32308 ms - **Static scan time:** 157 ms - **AI review time:** 43438 ms - **Total time:** 75904 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 identified in the inspected JavaScript. The CLI delegates its commands to shipped native binaries whose behavior could not be resolved from available offline analysis. - **Trigger:** Installing with npm may stage a platform binary; invoking the CLI runs the matching binary. - **Impact:** The native CLI behavior remains unresolved, so its effects cannot be established from inspected source. - **Evidence paths:** .lpm-inspection-9i0jW5/1-3ce77fe2b2bc.txt, .lpm-inspection-9i0jW5/3-811ec985ed00.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T11:59:32.238Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer can replace the JavaScript shim with a native executable, and the shim forwards CLI arguments to that executable. - **Rationale:** The JavaScript installer and launcher show ordinary binary setup and command forwarding, but the native CLI is the package’s primary runtime and its behavior remains materially unresolved. Manual review is needed to assess those binaries. - **Files touched:** install.js, bin/tm.js, native/linux-arm64/tm, native/win32-x64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 86.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall runs an installer that conditionally stages the platform binary and replaces the CLI shim after a version check., The CLI shim launches the matching native binary and forwards its arguments., Offline analysis could not resolve behavior in the Linux ARM binary or fully inspect the Windows x64 binary. - **Evidence against:** The installer exits on Windows and when the package manager is not npm., The installer only replaces the shim after the staged binary runs with --version. ## Affected versions and remediation This report applies to teammesh@0.19.1. - Review the evidence and your use of teammesh@0.19.1 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.
