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 script is an install-time behavior, but its command and configuration are consistent with IBM telemetry and do not establish malicious activity. The library entrypoint contains layout exports, with no suspicious execution or network code found in the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-10T01:32:11.361Z - **Finished:** 2026-10-10T01:32:34.258Z - **Download time:** 1034 ms - **Static scan time:** 41 ms - **AI review time:** 21821 ms - **Total time:** 22897 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 malicious attack surface was identified. The package has a postinstall telemetry hook configured for IBM’s telemetry service. - **Trigger:** The postinstall hook runs during package installation. - **Impact:** The inspected source does not establish harmful collection, unauthorized changes, or code execution beyond the telemetry hook. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T01:32:34.258Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It invokes the IBM telemetry command with telemetry.yml, which names an IBM endpoint and configures no npm dependency or JavaScript function collection. - **Rationale:** The postinstall script is an install-time behavior, but its command and configuration are consistent with IBM telemetry and do not establish malicious activity. The library entrypoint contains layout exports, with no suspicious execution or network code found in the inspected source. - **Network endpoints:** https://www-api.ibm.com/ibm-telemetry/v1/metrics ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports layout values through its library entrypoint., The postinstall hook invokes IBM telemetry using the package’s telemetry configuration., The telemetry configuration points to IBM’s telemetry endpoint and sets npm dependency collection to null and JavaScript function collection to empty. ## Affected versions and remediation This report applies to @carbon/layout@11.61.0. - Review the evidence and your use of @carbon/layout@11.61.0 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.
