## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 4.1.17
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The AI encoding feature has a plausible reason to process model properties, and the transfer requires an explicit start() call. Because the package sends that project data to a hard-coded third-party service without a visible disclosure or consent step, treat it as a runtime data-sharing risk and warn rather than block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious

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:** OneClickEncoding sends selected BIM model properties to DeepSeek without a visible disclosure or consent step in the package source.

- **Trigger:** An application calls oneClickEncoding.start().

- **Impact:** Project model properties are shared with a third-party service; the package does not establish that users are informed before the transfer.

- **Evidence paths:** dist/chunks/EngineKernel-Bzn2f2uI.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T03:22:16.324Z

### AI review details

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

- **Mechanism:** The method collects properties from matching model components and posts them in batches to https://api.deepseek.com/v1/chat/completions with a bundled bearer key.

- **Rationale:** The AI encoding feature has a plausible reason to process model properties, and the transfer requires an explicit start() call. Because the package sends that project data to a hard-coded third-party service without a visible disclosure or consent step, treat it as a runtime data-sharing risk and warn rather than block.

- **Files touched:** dist/chunks/EngineKernel-Bzn2f2uI.js

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The engine creates a OneClickEncoding instance during initialization., Its start() method gathers matching model components and their properties, then sends batches for encoding., The chat request posts those batches to api.deepseek.com using a hard-coded bearer key., The package source does not show a disclosure or consent step explaining that model properties go to DeepSeek.

- **Evidence against:** The network request is reached through the explicit start() method; constructing the feature alone does not send model data., package.json declares no install, preinstall, or postinstall lifecycle script., Sending model properties to an AI service is consistent with the encoding feature’s purpose.

## Affected versions and remediation
