## 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:** 4.1.6
- **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.

Source inspection found a caller-started model encoding feature that sends model properties to DeepSeek, with no confirmed attack behavior. A clean verdict requires citations for more distinct paths than the 256-citation limit allows, so this review cannot certify the full required coverage.

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:** The package includes an optional model encoding feature that sends model properties to DeepSeek when started. The inspected source did not establish malicious behavior.

- **Trigger:** A consumer calls OneClickEncoding.start on an engine instance.

- **Impact:** Model property data is disclosed to the configured AI service; the reviewed source does not show automatic activation or credential theft.

- **Evidence paths:** dist/chunks/EngineKernel-gFA8Pls7.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-25T22:28:05.492Z

### AI review details

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

- **Mechanism:** The helper collects properties from loaded model elements and posts them to the DeepSeek chat completions endpoint using a default API key.

- **Rationale:** Source inspection found a caller-started model encoding feature that sends model properties to DeepSeek, with no confirmed attack behavior. A clean verdict requires citations for more distinct paths than the 256-citation limit allows, so this review cannot certify the full required coverage.

- **Files touched:** package.json, dist/chunks/EngineKernel-gFA8Pls7.js, dist/index.d.ts

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

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 76.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The package manifest exposes bundled JavaScript entrypoints for a library., The engine creates a OneClickEncoding helper with a default DeepSeek endpoint and API key; its start method gathers model properties and its chat method sends requests to that endpoint., The declarations expose OneClickEncoding.start and chat; source inspection found no automatic call to start in the engine constructor.
