## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 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:** 0.9.9
- **Selected version is latest:** Yes
- **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.

The bundled entry polls only the user-configured API Spector service and returns results for its assigned checks. Its script execution and network activity match the package's stated monitoring purpose, and the scanner's redirect and payload-loader leads were not supported by the reviewed application code.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-11-04T14:00:32.657Z
- **Finished:** 2026-11-04T14:02:02.842Z
- **Download time:** 1014 ms
- **Static scan time:** 6736 ms
- **AI review time:** 82434 ms
- **Total time:** 90185 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 attack identified; the package acts as a private API-monitoring runner.

- **Trigger:** The user starts the CLI with APP\_URL and an agent or runtime token configured.

- **Impact:** Observed network and script execution support the documented monitoring feature; no unrelated credential collection or fixed unofficial gateway was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-04T14:02:02.842Z

### AI review details

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

- **Mechanism:** It polls the configured service for due checks, runs those checks, and posts their results back to the configured service.

- **Rationale:** The bundled entry polls only the user-configured API Spector service and returns results for its assigned checks. Its script execution and network activity match the package's stated monitoring purpose, and the scanner's redirect and payload-loader leads were not supported by the reviewed application code.

- **Network endpoints:** ${APP\_URL}/api/monitor-runtime/due, ${APP\_URL}/api/monitor-runtime/{id}/result

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exposes dist/index.cjs as both the CLI and the package main, with no lifecycle scripts present., The README says APP\_URL and AGENT\_TOKEN are required and describes the agent as polling API Spector Cloud for due checks and returning results., Runtime requests use the configured APP\_URL and environment-provided AGENT\_TOKEN or RUNTIME\_TOKEN., The runner polls the configured service's due-feed endpoint and posts monitor results to that same service., The runner executes check scripts in a sandbox with a timeout; the README describes pre/post scripts as part of the API-check engine.
