## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 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:** 1.52.8
- **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.

Inspected source shows a guarded, repair-only postinstall path and CLI-exposed agent integration. The static warnings do not establish malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-10-09T05:43:47.722Z

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 attack surface was identified. The install hook only attempts repair of a previously installed Codex wrapper, and agent integration is exposed through CLI setup.

- **Trigger:** Package installation invokes the postinstall wrapper; CLI commands can explicitly install agent integrations.

- **Impact:** No unconsented broad agent configuration mutation, credential exfiltration, or other concrete attack behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T05:44:25.789Z

### AI review details

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

- **Mechanism:** Postinstall calls a repair routine that requires existing wrapper metadata. The inspected integration declarations expose install and uninstall functions.

- **Rationale:** Inspected source shows a guarded, repair-only postinstall path and CLI-exposed agent integration. The static warnings do not establish malicious behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 89.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall entry invokes a small wrapper that imports the compiled postinstall module., The postinstall module attempts wrapper repair; repair returns without changing anything when no prior wrapper metadata exists., Repair is limited to an existing opted-in Codex wrapper, while integration installation is exposed through the CLI., Capture code reads the user's Claude project directory as local input; inspected code shows no network send there., The embedding provider uses an API-backed embedding path, consistent with the package's stated embedding functionality.
