## 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:** 4.1.15
- **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 flagged network behavior belongs to an optional BIM encoding feature: it reads component properties and sends them to DeepSeek only when its start method is called. Package metadata shows no install hook, and engine initialization only constructs the feature object.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-30T20:15:40.447Z

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. An optional BIM encoding feature sends model component properties to DeepSeek when its start method is called.

- **Trigger:** A caller explicitly invokes the engine's oneClickEncoding.start() method.

- **Impact:** BIM component properties are disclosed to DeepSeek as part of the requested encoding feature.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T20:16:46.482Z

### AI review details

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

- **Mechanism:** The feature filters BIM components, gathers their properties, and posts them to the DeepSeek chat completions API using a package-provided API key.

- **Rationale:** The flagged network behavior belongs to an optional BIM encoding feature: it reads component properties and sends them to DeepSeek only when its start method is called. Package metadata shows no install hook, and engine initialization only constructs the feature object.

- **Files touched:** dist/chunks/engine-3d-D9NbR8ef.js

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

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package entry points load the BIM SDK bundles, and package.json declares no install lifecycle scripts., The DeepSeek API request is in an optional encoding method that reads BIM component properties; it is not invoked by the SDK constructor., The request sends those properties to api.deepseek.com using a key configured by the package, with an optional constructor override.

- **Evidence against:** The SDK initializes a OneClickEncoding instance when an engine is created., The optional encoding feature sends model property data to an external service when started.

## Affected versions and remediation
