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 found that the registry-install postinstall path exits before running package-manager commands. The flagged process, network, and dynamic-code patterns support the package’s source-checkout setup, GPU reporting, update notification, and bundled Jupyter frontend; no concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-16T13:29:12.960Z - **Finished:** 2026-10-16T13:33:34.556Z - **Download time:** 776 ms - **Static scan time:** 3057 ms - **AI review time:** 257762 ms - **Total time:** 261596 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 inspected install, launcher, GPU reporting, update check, and bundled frontend behavior align with the notebook package’s functionality. - **Trigger:** Installation or normal use of the notebook; the postinstall script exits when the package is installed under node\_modules. - **Impact:** No unconsented installation mutation or other concrete attack effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-16T13:33:34.556Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The source-checkout postinstall installs subpackage dependencies, the launcher starts the bundled server, and fixed shell commands collect GPU information. The update check retrieves package version information from the npm registry. - **Rationale:** Source inspection found that the registry-install postinstall path exits before running package-manager commands. The flagged process, network, and dynamic-code patterns support the package’s source-checkout setup, GPU reporting, update notification, and bundled Jupyter frontend; no concrete attack behavior was established. - **Files touched:** package.json, scripts/postinstall.cjs, bin/nebula-notebook.js, node-server/dist/resources/resource-service.js, node-server/dist/update-check.js, node-server/dist/index.js, dist/assets/index-pBlQK-xI.js, dist/assets/index-BdZ\_Kjti.js, dist/assets/services-shim-zXtxqviK.js ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares the postinstall script; the script exits when installed under node\_modules and only installs subpackage dependencies in a source checkout., The launcher starts the package’s bundled server and forwards the caller’s arguments., The flagged shell calls use fixed NVIDIA and AMD GPU information commands., The update checker contacts the npm registry for version information and is started as a notify-only check outside client mode., The frontend’s file write is an application API request, and the other flagged bundle code reads Jupyter configuration through its configured path., The shim imports the main frontend bundle and contains bundled utility code. ## Affected versions and remediation This report applies to nebula-notebook@0.2.79. - Review the evidence and your use of nebula-notebook@0.2.79 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.
