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. Source inspection shows a global-only postinstall message and an issuer match before stored credentials are used. The flagged agent location is explanatory bundled text, and the inspected code does not establish an active attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T02:15:36.957Z - **Finished:** 2026-10-10T02:16:30.696Z - **Download time:** 762 ms - **Static scan time:** 1679 ms - **AI review time:** 51297 ms - **Total time:** 53739 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 prints guidance, while the inspected credential flow checks that the saved issuer matches the active API URL. - **Trigger:** Package installation; setup is described as a later user-guided action. - **Impact:** No confirmed credential exposure or unconsented agent configuration change was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T02:16:30.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The global postinstall branch writes setup guidance to stdout. The API client chooses the configured or default service URL, and the inspected caller refuses credentials when their saved issuer differs. - **Rationale:** Source inspection shows a global-only postinstall message and an issuer match before stored credentials are used. The flagged agent location is explanatory bundled text, and the inspected code does not establish an active attack surface. - **Files touched:** package.json, scripts/postinstall.mjs, dist/index.js - **Network endpoints:** https://api.memgineering.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json routes postinstall to a script that only prints setup guidance when npm installs globally., The postinstall guidance says setup is not run there because it asks the user what to install and whether the tool may update itself., The API URL defaults to the package service, and credentials are used only when their saved issuing URL matches the active URL., The flagged dist location is explanatory text about the setup hub; it does not perform an agent configuration write. - **Evidence against:** The CLI supports an operator-configured API URL, but the inspected credential path checks that URL against the saved credential issuer before use. ## Affected versions and remediation This report applies to memgineering@0.9.1. - Review the evidence and your use of memgineering@0.9.1 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.
