## 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:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 4.0.16
- **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 source shows a user-invoked encoding feature that sends selected model properties to its configured provider, so it does not establish covert exfiltration or malicious intent. The default bearer-style key is embedded in the published bundle, creating unresolved exposure and possible unauthorized use if the key is valid; warn rather than block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 78.0%

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 confirmed malicious attack was identified. The published client bundle contains a default provider credential, and the encoding feature sends model coding properties to DeepSeek when started.

- **Trigger:** A caller invokes OneClickEncoding.start() or chat().

- **Impact:** If the bundled key is valid, package consumers can extract and reuse it; model coding properties are disclosed to the provider during encoding.

- **Evidence paths:** package.json, dist/index.d.ts, dist/chunks/engine-3d-B0D38zLu.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-25T22:20:33.023Z

### AI review details

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

- **Mechanism:** The SDK uses its bundled default bearer key for a DeepSeek chat request; start() gathers selected model element properties and submits them in batches.

- **Rationale:** The source shows a user-invoked encoding feature that sends selected model properties to its configured provider, so it does not establish covert exfiltration or malicious intent. The default bearer-style key is embedded in the published bundle, creating unresolved exposure and possible unauthorized use if the key is valid; warn rather than block.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 78.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package entry points load the bundled SDK., The public OneClickEncoding API exposes start() and chat()., The SDK embeds a bearer-style provider key as its default and logs part of it during initialization., Calling start() selects model elements, gathers coding properties, and sends batches to DeepSeek.

- **Evidence against:** The external request is part of the named encoding feature and runs through an explicit start() call., The inspected source does not establish that the embedded key is valid or that the transfer is hidden or install-triggered.
