## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 23 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:** 0.3.35
- **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.

Static inspection does not substantiate the scanner’s malicious label. The compressed runtime is an identified, hash-recorded dependency workspace, while the flagged AI-agent directory mutation is confined to an explicit installer command.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-08-23T05:39:10.839Z
- **Finished:** 2026-08-23T05:40:32.588Z
- **Download time:** 9142 ms
- **Static scan time:** 8978 ms
- **AI review time:** 63628 ms
- **Total time:** 81749 ms

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 install-time or runtime attack surface. npm preinstall only performs a Node-version check; package-owned runtime setup and optional skill installation are user-invoked or confined to Feynman paths.

- **Trigger:** npm install runs the version checker; running feynman starts its package-local runtime setup.

- **Impact:** No unconsented credential harvesting, exfiltration, remote payload execution, or foreign AI-agent control-surface mutation was established.

- **Evidence paths:** package.json, scripts/check-node-version.mjs, bin/feynman.js, scripts/patch-embedded-pi.mjs, .feynman/runtime-workspace.sha256, scripts/install/install-skills.sh

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T05:40:32.588Z

### AI review details

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

- **Mechanism:** local version validation and package-owned CLI runtime initialization

- **Rationale:** Static inspection does not substantiate the scanner’s malicious label. The compressed runtime is an identified, hash-recorded dependency workspace, while the flagged AI-agent directory mutation is confined to an explicit installer command.

- **Files touched:** package.json, scripts/check-node-version.mjs, bin/feynman.js, scripts/patch-embedded-pi.mjs, .feynman/runtime-workspace.tgz, .feynman/runtime-workspace.sha256, scripts/install/install-skills.sh, scripts/install/install.sh

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** The only npm lifecycle hook runs a local Node-version compatibility check., The preinstall source only reports unsupported versions and may exit; it has no network, file-write, or child-process action., The CLI imports package-local runtime setup and application entrypoints., The bundled runtime archive has a matching recorded SHA-256 and declares Pi-related runtime dependencies., The skills installer modifies AI-agent skill directories only when explicitly invoked with a chosen scope.

## Affected versions and remediation
