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 CLI wrapper show a bounded native-binary selection and execution flow. Because the shipped executables could not be adequately inspected, their behavior remains materially unresolved; no specific attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-18T22:52:33.827Z - **Finished:** 2026-10-18T22:53:30.153Z - **Download time:** 4620 ms - **Static scan time:** 155 ms - **AI review time:** 51551 ms - **Total time:** 56326 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 attack was established in the inspected JavaScript. The package automatically runs and replaces its CLI shim with a bundled native executable, whose behavior remains unresolved. - **Trigger:** Package installation through npm on a supported non-Windows platform, or running the tm CLI. - **Impact:** The native executable's behavior cannot be determined from the available offline analyses, so its effects remain unknown. - **Evidence paths:** .lpm-inspection-Omsv6P/0-dbaa0040773f.txt, .lpm-inspection-Omsv6P/1-4c9d903c657e.txt, .lpm-inspection-Omsv6P/2-f536d786c443.txt, .lpm-inspection-Omsv6P/3-523f3700325c.txt, .lpm-inspection-Omsv6P/4-cf212c66464f.txt, .lpm-inspection-Omsv6P/5-77a538ddd3e4.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T22:53:30.153Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook tests a matching native binary and replaces the JavaScript shim; the shim forwards CLI arguments to that binary. - **Rationale:** The JavaScript installer and CLI wrapper show a bounded native-binary selection and execution flow. Because the shipped executables could not be adequately inspected, their behavior remains materially unresolved; no specific attack was established. - **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:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs install.js as a postinstall hook., On supported npm platforms, install.js selects a matching native binary, runs it with --version, and replaces bin/tm.js if it succeeds., bin/tm.js forwards the CLI arguments to the matching native binary., Offline analyses could not inspect five shipped binaries and only partially analyzed the Windows x64 binary. ## Affected versions and remediation This report applies to teammesh@0.17.0. - Review the evidence and your use of teammesh@0.17.0 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** native/win32-arm64/tm.exe - **Public source:** [View source]() Package ships native binary artifacts. Public source snippet (untrusted): ```text path = native/win32-arm64/tm.exe kind = native_binary sizeBytes = 7768064 magicHex = [redacted] ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 78.0% - **Path:** install.js - **Public source:** [View source]() On supported npm platforms, install.js selects a matching native binary, runs it with --version, and replaces bin/tm.js if it succeeds. Public source snippet (untrusted): ```javascript if (process.platform === "win32") process.exit(0); if (!(process.env.npm[redacted] ?? "").startsWith("npm/")) process.exit(0); const binary = path.join(__dirname, "native", `${process.platform}-${process.arch}`, "tm"); if (!fs.existsSync(binary)) process.exit(0); const shim = path.join(__dirname, "bin", "tm.js"); const staged = `${shim}.native`; try { fs.copyFileSync(binary, staged); fs.chmodSync(staged, 0o755); // Only swap in a binary that actually runs here. execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSync(staged, shim); } catch ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 78.0% - **Path:** bin/tm.js - **Public source:** [View source]() bin/tm.js forwards the CLI arguments to the matching native binary. Public source snippet (untrusted): ```javascript const platform = `${process.platform}-${process.arch}`; const binary = path.join(__dirname, "..", "native", platform, process.platform === "win32" ?
