Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.1.34 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 install hook prepares Rakumux's bundled binaries and scripts in its own package directory. The inspected source shows no install-time data collection, unrelated network contact, or concealed behavior; the native binaries are opaque but are consistent with the package's stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-30T13:01:54.344Z - **Finished:** 2026-10-30T13:02:29.242Z - **Download time:** 1522 ms - **Static scan time:** 334 ms - **AI review time:** 33041 ms - **Total time:** 34898 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 install hook prepares the package's own launch assets. - **Trigger:** The postinstall lifecycle hook runs during installation; commands run when invoked by the user. - **Impact:** No malicious impact was identified in the inspected source. The bundled native executables are not readable source, but their installation and invocation fit the package's stated purpose. - **Review source:** ai\_review - **Reviewed:** 2026-10-30T13:02:29.242Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install copies bundled platform binaries and shell scripts into dist/. Command wrappers pass arguments to those tools. - **Rationale:** The install hook prepares Rakumux's bundled binaries and scripts in its own package directory. The inspected source shows no install-time data collection, unrelated network contact, or concealed behavior; the native binaries are opaque but are consistent with the package's stated purpose. - **Files touched:** dist/, resources/prebuilt/, resources/scripts/ - **Network endpoints:** https://github.com/humanunsupervised/rakumux ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs install.js to prepare the package., Setup copies launcher scripts and platform-specific bundled binaries into the package's dist directory., The command wrapper forwards user arguments to the selected Rakumux command. - **Evidence against:** The inspected install path does not show external contact or collection of host, user, project, or credential data., The install hook prepares assets for a terminal session manager, consistent with the package description. ## Affected versions and remediation This report applies to rakumux@0.1.34. - Review the evidence and your use of rakumux@0.1.34 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.
