## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 4.0.19
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The inspected transfer is reachable through an explicit model-encoding API and appears aligned with that feature; no install-time attack was found. A clean verdict requires citations for more paths than the output limit allows, so this review remains unresolved on coverage grounds.

## Latest scan

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 attack was identified in the inspected source. The SDK includes a model-encoding feature that sends selected component properties to DeepSeek when its start method is called.

- **Trigger:** A caller invokes the exposed encoding start method.

- **Impact:** Selected model properties leave the application for processing by the configured service; the inspected path does not establish malicious collection.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-25T22:20:39.410Z

### AI review details

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

- **Mechanism:** The method gathers matching component properties and posts them as JSON to the DeepSeek chat API using a bundled default key.

- **Rationale:** The inspected transfer is reachable through an explicit model-encoding API and appears aligned with that feature; no install-time attack was found. A clean verdict requires citations for more paths than the output limit allows, so this review remains unresolved on coverage grounds.

- **Files touched:** dist/chunks/EngineKernel-CZX0Omjs.js

- **Network endpoints:** api.deepseek.com

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 63.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json exposes runtime entrypoints and defines no install lifecycle hook., The SDK creates and publicly exposes the encoding feature; its start method gathers selected model properties and sends batched data to chat., The chat method posts to the DeepSeek API with a bundled default key. The transfer is reachable through an explicit encoding API call., The clean-review citation requirement exceeds the 256-citation limit.

- **Evidence against:** No install-time execution or automatic invocation of the encoding method was found in the inspected source., The external request is part of the package’s model-encoding feature; the inspected code does not establish unrelated collection or malicious use.

## Affected versions and remediation
