## 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:** 4.5.89
- **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.

The scanner’s credential and command-output indicators were not confirmed as an attack by source inspection. The manifest has no lifecycle hook, the flagged agent path block only classifies project paths, and the observed telemetry carries limited usage data to the configured Hub.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 90.0%
- **Started:** 2026-10-18T14:02:58.269Z

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 CLI sends limited command telemetry to its configured Hub endpoint when a command runs.

- **Trigger:** Running a CLI command.

- **Impact:** The inspected behavior reports basic CLI usage details; it does not establish credential disclosure or agent configuration mutation.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T14:03:34.996Z

### AI review details

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

- **Mechanism:** A pre-action callback sends the command name, version, CI status, and operating system to the Hub telemetry route; the code supports an MMI\_TELEMETRY=off setting.

- **Rationale:** The scanner’s credential and command-output indicators were not confirmed as an attack by source inspection. The manifest has no lifecycle hook, the flagged agent path block only classifies project paths, and the observed telemetry carries limited usage data to the configured Hub.

- **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json defines no lifecycle scripts, and the CLI bundle is a shipped package file., The agent path list is used to recognize agent configuration paths when checking project changes; the cited block contains no configuration write., CLI telemetry is triggered by a CLI pre-action and reports the invoked command, package version, CI status, and operating system to the configured Hub endpoint., The telemetry endpoint uses the package’s default Hub URL; the inspected payload contains no credentials or environment values.
