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 stages bundled assets inside the package, and the launcher behavior matches a terminal session manager. Its background update check queries package version information without sending user or project data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-04T07:33:35.552Z - **Finished:** 2026-11-04T07:34:38.031Z - **Download time:** 1025 ms - **Static scan time:** 315 ms - **AI review time:** 61138 ms - **Total time:** 62479 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. Install setup stages the package's bundled launchers and binaries; runtime update checks request version information. - **Trigger:** Postinstall performs setup; the TUI may start a daily background update check. - **Impact:** No evidence of credential, host, project, or other user data collection or transmission was found. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T07:34:38.031Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies files into dist. The update check uses npm or Homebrew commands to look up the Rakumux version. - **Rationale:** The postinstall hook stages bundled assets inside the package, and the launcher behavior matches a terminal session manager. Its background update check queries package version information without sending user or project data. - **Files touched:** dist/, ~/.cache/rakumux/last\_update\_check, ${RAKUMUX\_HOME:-$HOME/.rakumux}/history/\.log ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs setup that copies launcher scripts and prebuilt platform binaries into the package's dist directory., Prebuilt binaries are selected by the current platform and copied from the package's bundled resources., The install path contains no code that sends host, project, environment, or credential data., The background update check runs for the TUI and queries npm or Homebrew for Rakumux version information. - **Evidence against:** The package has a postinstall lifecycle script., Launching the TUI can trigger a daily background update check. ## Affected versions and remediation This report applies to rakumux@0.1.45. - Review the evidence and your use of rakumux@0.1.45 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.
