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 readable install and launcher code show a platform-specific binary setup and dispatch, but do not establish an attack. The shipped native executables contain the CLI behavior and could not be adequately inspected, so the risk remains unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-18T02:58:35.732Z - **Finished:** 2026-10-18T02:59:09.343Z - **Download time:** 3553 ms - **Static scan time:** 143 ms - **AI review time:** 29915 ms - **Total time:** 33611 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 native executable behavior remains unresolved because the available offline analysis could not inspect it. - **Trigger:** Running the teammesh CLI invokes the native executable; npm installation may replace the JavaScript shim with that executable. - **Impact:** Unknown; the native program is the main unresolved behavior. - **Evidence paths:** .lpm-inspection-164BtR/5-d8b0609d2ef5.txt, .lpm-inspection-164BtR/3-22c211a1e749.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T02:59:09.343Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher selects the executable for the current platform and forwards CLI arguments. Its native behavior could not be assessed from the available inspection. - **Rationale:** The readable install and launcher code show a platform-specific binary setup and dispatch, but do not establish an attack. The shipped native executables contain the CLI behavior and could not be adequately inspected, so the risk remains unresolved. - **Files touched:** package.json, install.js, bin/tm.js, native/linux-x64/tm, native/win32-x64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 96.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook installs a platform-specific native executable, and the launcher runs it with the supplied arguments., Offline analysis could not inspect the Linux executable and left its behavior unresolved; Windows analysis also left native call targets uninspected. - **Evidence against:** The postinstall script only attempts a binary replacement for npm on non-Windows platforms, and keeps the JavaScript shim if replacement fails., The launcher passes command-line arguments through to the native executable; the inspected JavaScript does not establish malicious behavior. ## Affected versions and remediation This report applies to teammesh@0.6.0. - Review the evidence and your use of teammesh@0.6.0 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.
