Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook only stages and version-checks the package's own platform binary before replacing the CLI shim. The native artifacts are partly opaque and contain a Sentry crash-report marker, but the available evidence does not establish malicious or undisclosed collection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-02T18:38:59.658Z - **Finished:** 2026-11-02T18:40:10.992Z - **Download time:** 12328 ms - **Static scan time:** 161 ms - **AI review time:** 58844 ms - **Total time:** 71334 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 identified. The postinstall hook installs the packaged CLI binary, and the launcher forwards user-supplied arguments to it. - **Trigger:** Postinstall runs automatically; normal CLI behavior requires a user command. - **Impact:** No malicious collection, unrelated network destination, or unauthorized account action was established from the reviewed source. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T18:40:10.992Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook stages and version-checks the platform binary before replacing \`bin/tm.js\`. The readable native strings name TeamMesh API/sync services and a Sentry crash-report endpoint. - **Rationale:** The postinstall hook only stages and version-checks the package's own platform binary before replacing the CLI shim. The native artifacts are partly opaque and contain a Sentry crash-report marker, but the available evidence does not establish malicious or undisclosed collection. - **Files touched:** bin/tm.js, bin/tm.js.native - **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes \`tm\` as a CLI and runs \`install.js\` as its postinstall hook., The installer skips Windows and non-npm installs., The installer stages the package's platform binary, checks it with \`--version\`, then replaces the launcher., The JavaScript launcher runs the matching packaged native binary with the user's supplied arguments., The readable binary view contains TeamMesh API and sync endpoints, plus a Sentry DSN and \`TM\_CRASH\_REPORTS\` marker; no credential theft or unrelated collector was established. - **Evidence against:** Most native binaries could not be structurally analyzed; the Windows x64 view is limited., The native binary contains a Sentry endpoint and crash-report environment marker, but the readable view does not establish whether reporting is enabled by default. ## Affected versions and remediation This report applies to teammesh@0.36.0. - Review the evidence and your use of teammesh@0.36.0 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.
