## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 14 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:** 4.1.19
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The public encoding feature sends model properties to DeepSeek with a bundled key, without an evident user-configured service or key. The request is tied to an explicit feature call, so this is suspicious undisclosed external data handling rather than malicious automatic exfiltration.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 92.0%
- **Started:** 2026-11-04T06:37:06.625Z

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 encoding feature sends BIM component properties to DeepSeek using a package-bundled API key.

- **Trigger:** A caller invokes \`oneClickEncoding.start()\`.

- **Impact:** Model properties are disclosed to an external AI service without an evident user-configured endpoint or key.

- **Evidence paths:** dist/chunks/EngineKernel-CHERjTSQ.js, dist/index.d.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-11-04T06:39:06.744Z

### AI review details

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

- **Mechanism:** The method queries properties for matching model components, batches the results, and POSTs each batch to DeepSeek’s chat completions endpoint.

- **Rationale:** The public encoding feature sends model properties to DeepSeek with a bundled key, without an evident user-configured service or key. The request is tied to an explicit feature call, so this is suspicious undisclosed external data handling rather than malicious automatic exfiltration.

- **Files touched:** localStorage key \`bim\_encoding\_${url}\`

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 92.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The encoding feature defaults to a hard-coded API key and \`https://api.deepseek.com\`., Its \`start()\` method collects model component properties and passes them as JSON to the chat method., The chat method POSTs that content to DeepSeek using the API key in a Bearer header., The package’s type declarations expose \`OneClickEncoding.start()\` as a callable method., The engine constructor creates the encoding feature, while the network request is reached through its \`start()\` flow.

- **Evidence against:** The package scripts shown are development, build, and test commands; no install lifecycle script is declared., The source ties the external request to a feature for generating model encodings, rather than an install-time or import-time data collection flow.
