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 a conditional install-time native execution path and runtime delegation to shipped binaries, while offline inspection leaves their behavior unresolved. This does not establish malicious behavior, so manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-17T19:17:08.690Z - **Finished:** 2026-10-17T19:17:43.017Z - **Download time:** 6956 ms - **Static scan time:** 78 ms - **AI review time:** 27293 ms - **Total time:** 34327 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 specific attack was confirmed, but the installer executes a shipped native binary and the CLI delegates to that binary. Its behavior could not be resolved from the available offline analyses. - **Trigger:** Installation through npm on a non-Windows platform runs the installer; invoking tm launches the platform binary. - **Impact:** The effects of the native executable remain unknown, including during its installation-time version check. - **Evidence paths:** .lpm-inspection-XwwyuC/5-f5668206c889.txt, .lpm-inspection-XwwyuC/3-8ac2942f0d70.txt, .lpm-inspection-XwwyuC/1-b25e79e83bda.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-17T19:17:43.017Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer stages the binary, runs it with --version, and may replace bin/tm.js. The CLI shim launches the native binary with the supplied arguments. - **Rationale:** The source shows a conditional install-time native execution path and runtime delegation to shipped binaries, while offline inspection leaves their behavior unresolved. This does not establish malicious behavior, so manual review is warranted. - **Files touched:** package.json, install.js, bin/tm.js, native/linux-x64/tm, 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:** package.json runs install.js during postinstall., install.js selects a platform binary, copies it over the CLI shim, and runs it with --version during installation., bin/tm.js launches the platform binary with the CLI arguments and inherited input/output., The inspected Linux and Windows native analyses leave executable behavior unresolved. - **Evidence against:** The installer skips Windows and non-npm installs, and removes the staged copy if its check fails., The installer describes the shim replacement as a startup optimization for the CLI. ## Affected versions and remediation This report applies to teammesh@0.2.0. - Review the evidence and your use of teammesh@0.2.0 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.
