Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 17 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:** 0.2.37 - **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 concerning lifecycle and child-process primitives are limited to transparent repository setup or launching the bundled server. The registry-install guard prevents the package-manager commands from executing when this package is installed as a dependency. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-05T05:19:51.955Z - **Finished:** 2026-09-05T05:22:44.974Z - **Download time:** 505 ms - **Static scan time:** 3662 ms - **AI review time:** 168851 ms - **Total time:** 173019 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 confirmed malicious attack surface was established. The install hook is inactive for normal registry installation. - **Trigger:** A source-checkout installation can invoke the helper; normal package use starts its local server. - **Impact:** No confirmed unconsented mutation, exfiltration, or remote code execution. - **Review source:** ai\_review - **Reviewed:** 2026-09-05T05:22:44.974Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Repository-only subpackage setup and local server launch. - **Rationale:** The concerning lifecycle and child-process primitives are limited to transparent repository setup or launching the bundled server. The registry-install guard prevents the package-manager commands from executing when this package is installed as a dependency. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest automatically invokes a post-install helper., The helper contains package-manager commands, but it exits when installed from node\_modules., The command-line launcher starts the bundled local server with user-supplied arguments., The flagged frontend file is a prebuilt asset map, not an install-time loader. - **Evidence against:** No runtime dependency selects another nebula-notebook release., The post-install helper does not run its install commands for a registry installation., The launcher only starts the package's local server and inherits its process environment., No source inspected shows credential collection, data exfiltration, foreign agent configuration writes, or remote payload execution. ## Affected versions and remediation This report applies to nebula-notebook@0.2.37. - Review the evidence and your use of nebula-notebook@0.2.37 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.
