## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 28 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:** 0.2.94
- **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 install hook exits for npm-installed copies and otherwise builds the repository’s own subpackages. Reviewed outbound behavior is limited to a version lookup and cluster registration with a user-configured server; no malicious credential flow was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-11-01T15:27:18.028Z
- **Finished:** 2026-11-01T15:28:13.058Z
- **Download time:** 520 ms
- **Static scan time:** 3171 ms
- **AI review time:** 51338 ms
- **Total time:** 55030 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. Reviewed install and startup behavior serves repository setup, configured cluster operation, and a package-version check.

- **Trigger:** npm install runs the postinstall hook; invoking the CLI starts the bundled server and its startup tasks.

- **Impact:** No unconsented collection or unrelated credential transfer was identified in the reviewed paths.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-01T15:28:13.058Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The hook exits from node\_modules and otherwise installs/builds local subpackages. Cluster registration uses the configured NEBULA\_MAIN\_SERVER; the update check fetches the package’s latest version from the npm registry.

- **Rationale:** The install hook exits for npm-installed copies and otherwise builds the repository’s own subpackages. Reviewed outbound behavior is limited to a version lookup and cluster registration with a user-configured server; no malicious credential flow was found.

- **Files touched:** scripts/postinstall.cjs, node-server/dist/index.js, node-server/dist/cluster/client-registration.js, node-server/dist/update-check.js

- **Network endpoints:** registry.npmjs.org, NEBULA\_MAIN\_SERVER (user-configured)

### Review decision

- **Verdict:** Clean

- **Confidence:** 89.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall script exits when the package is installed under node\_modules; otherwise it installs/builds the repository’s subpackages., Cluster registration requires client mode and a main server URL from the user’s NEBULA\_MAIN\_SERVER setting., Cluster secrets and allocation tokens are sent to the configured main server as part of registration., The startup update check requests only the latest nebula-notebook version from registry.npmjs.org.

- **Evidence against:** The package defines a postinstall lifecycle script that runs npm install commands in repository subdirectories., The launcher starts a local bundled server that supports notebook kernels, filesystem operations, and terminal sessions.

## Affected versions and remediation

This report applies to nebula-notebook@0.2.94.

- Review the evidence and your use of nebula-notebook@0.2.94 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.
