## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 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:** 0.5.37
- **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.

Source inspection found a version-only preinstall check and a user-invoked project initialization command that creates missing files. The flagged network and credential references in the Hugging Face tools send tokens to the intended Hugging Face service; no concrete attack behavior was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 92.0%
- **Started:** 2026-10-12T08:42:17.355Z

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 in the inspected source. The install hook checks the Node version, and the project initialization writes files only when the user invokes its command.

- **Trigger:** Package installation triggers the preinstall version check; a user invokes the init command to create project files.

- **Impact:** No harmful effect was established; initialization may add the documented project files.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-12T08:43:12.992Z

### AI review details

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

- **Mechanism:** The preinstall script compares the installed Node.js version with a minimum. The init command creates missing project notes and AGENTS.md files in the working directory.

- **Rationale:** Source inspection found a version-only preinstall check and a user-invoked project initialization command that creates missing files. The flagged network and credential references in the Hugging Face tools send tokens to the intended Hugging Face service; no concrete attack behavior was found.

- **Files touched:** AGENTS.md, notes/, notes/session-logs/README.md

### Review decision

- **Verdict:** Clean

- **Confidence:** 92.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The preinstall hook only runs a Node.js version check; it does not install dependencies or mutate consumer configuration., The init command is user-invoked and creates missing project notes and AGENTS.md files under the current project directory., The launcher loads the CLI for normal use; its version-only path exits after reading package.json., Hugging Face tokens are attached to requests made by the Hugging Face research tools for their intended service., The inspected CLI excerpt handles command arguments and alpha command passthrough.
