## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 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:** 4.1.20
- **Selected version is latest:** Yes
- **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 flagged network behavior implements an AI-assisted BIM encoding feature: it gathers model properties and submits them to DeepSeek when started. The inspected manifest has no install lifecycle scripts, and no unrelated collection or attack behavior was identified.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-11-04T08:14:01.492Z

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 SDK includes an AI-assisted model-encoding feature that sends selected model properties to DeepSeek when started.

- **Trigger:** Calling OneClickEncoding.start().

- **Impact:** Model properties are sent to the AI service to generate encoding results; no unrelated credential collection or install-time behavior was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-04T08:15:18.871Z

### AI review details

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

- **Mechanism:** The method gathers properties from matching BIM model components, then submits them to https://api.deepseek.com/v1/chat/completions.

- **Rationale:** The flagged network behavior implements an AI-assisted BIM encoding feature: it gathers model properties and submits them to DeepSeek when started. The inspected manifest has no install lifecycle scripts, and no unrelated collection or attack behavior was identified.

- **Files touched:** dist/chunks/engine-3d-BJzGZJoM.js

- **Network endpoints:** https://api.deepseek.com/v1/chat/completions

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package is a BIM engine SDK and its main export is a built distribution bundle., OneClickEncoding.start() selects model components and requests their properties for encoding., The encoding feature sends the supplied data to DeepSeek’s chat completions endpoint using its configured or built-in API key.

- **Evidence against:** The network request is part of the named model-encoding feature and is reached through its start() method; no install hook is declared., The request sends model properties as the user message, not discovered credentials or unrelated files.

## Affected versions and remediation
