## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 21 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:** 0.21.28
- **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 no concrete attack behavior. The lifecycle hook’s runtime hydration is package-aligned, while agent and setup configuration changes are dispatched through the explicit CLI setup command.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-21T14:38:36.056Z
- **Finished:** 2026-10-21T14:41:05.272Z

- **Total time:** 149216 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 was identified in the inspected source. The install hook is limited to global installs and does not perform setup or credential transfer.

- **Trigger:** The postinstall hook runs during installation; its source returns without action for local installs. Setup requires invoking the separate CLI setup command.

- **Impact:** No harmful effect was established from the inspected behavior.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T14:41:05.272Z

### AI review details

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

- **Mechanism:** For global installs, postinstall hydrates the package’s native runtime and records an install version. Setup writes configured product files and preferences when explicitly invoked.

- **Rationale:** Source inspection found no concrete attack behavior. The lifecycle hook’s runtime hydration is package-aligned, while agent and setup configuration changes are dispatched through the explicit CLI setup command.

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json invokes the postinstall hook, but dist/scripts/postinstall.js returns immediately for local installs; on global installs it hydrates the package’s native runtime and records the installed version., dist/cli/index.js dispatches setup only for the explicit setup command. The inspected setup code writes setup preferences; the postinstall path does not call setup., The required runtime and agent integration paths reviewed contain CLI, state, authentication, and configuration behavior; no install-time credential transfer or unconsented broad agent configuration write was established., The inspected manifests for the prepared TOML, MCP SDK, and LZMA dependencies have no install lifecycle scripts. The secret-like test data is used in redaction tests.

- **Evidence against:** The test secret pattern is synthetic redaction-test input, not evidence of a package credential., The scanner’s install-time setup concern is not supported by the source: the lifecycle hook does not invoke setup, which is dispatched by the explicit CLI command.
