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 JavaScript installs and delegates to native binaries, which are the package's main runtime. Offline analysis left most builds unresolved and the Windows x64 build incomplete, so the package's behavior cannot be reliably classified from this inspection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-17T09:18:29.690Z - **Finished:** 2026-10-17T09:19:45.397Z - **Download time:** 1544 ms - **Static scan time:** 72 ms - **AI review time:** 74090 ms - **Total time:** 75707 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 installs a CLI that runs platform-specific native programs. Static inspection could not resolve most binaries and only partially inspected one Windows build, so their behavior needs review. - **Trigger:** The postinstall hook probes a native binary on supported npm Unix installs; invoking the CLI runs the platform binary with the supplied arguments. - **Impact:** The binaries' effects could not be assessed, and no concrete attack was established from the readable source. - **Evidence paths:** .lpm-inspection-QIUsHp/0-aa1cdb847e9a.txt, .lpm-inspection-QIUsHp/1-9ec688e10726.txt, .lpm-inspection-QIUsHp/2-71689762a115.txt, .lpm-inspection-QIUsHp/3-5efc5bf9e1a1.txt, .lpm-inspection-QIUsHp/4-585399367eff.txt, .lpm-inspection-QIUsHp/5-ada8c78deb7c.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-17T09:19:45.397Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer stages and executes the native program, while the CLI wrapper delegates execution to it. - **Rationale:** The readable JavaScript installs and delegates to native binaries, which are the package's main runtime. Offline analysis left most builds unresolved and the Windows x64 build incomplete, so the package's behavior cannot be reliably classified from this inspection. - **Files touched:** install.js, bin/tm.js, native/win32-arm64/tm.exe, native/linux-arm64/tm, native/darwin-x64/tm, native/win32-x64/tm.exe, native/darwin-arm64/tm, native/linux-x64/tm ### Review decision - **Verdict:** Manual Review - **Confidence:** 88.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest registers a CLI and a postinstall hook that runs the installer., On supported npm Unix installs, the installer selects the platform binary, runs it with a version argument, and replaces the JavaScript shim., The CLI wrapper launches the platform binary with the user's arguments., Offline analysis could not resolve five native builds and found uninspected call targets in the Windows x64 build. - **Evidence against:** The readable installer only stages, probes, and swaps the platform binary; no concrete attack behavior was established in the inspected JavaScript. ## Affected versions and remediation This report applies to teammesh@0.1.3. - Review the evidence and your use of teammesh@0.1.3 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.
