## 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:** 2.0.0
- **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 lifecycle hook delegates to a postinstall module that prints guidance and uses guarded repair behavior. Agent configuration changes and scheduling are associated with the explicit init flow, and the flagged child process supports package memory consolidation; no concrete attack behavior was established.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified in the inspected lifecycle or flagged source paths. Agent integration and scheduling are tied to the init flow, while postinstall prints setup guidance.

- **Trigger:** Package installation runs postinstall; agent integration and scheduling are activated through hippo init.

- **Impact:** The inspected behavior does not establish unauthorized agent control, credential exposure, or other malicious impact.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-11T23:40:43.550Z

### AI review details

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

- **Mechanism:** Postinstall performs guarded wrapper repair and prints opt-in guidance. The init flow installs hooks and schedules routine package work.

- **Rationale:** The lifecycle hook delegates to a postinstall module that prints guidance and uses guarded repair behavior. Agent configuration changes and scheduling are associated with the explicit init flow, and the flagged child process supports package memory consolidation; no concrete attack behavior was established.

### 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 runs a postinstall script that delegates to dist/postinstall.js., dist/cli/init.js detects existing agent markers, and integration changes are performed through the init flow; its patcher does not create missing instruction files., dist/cli/install-steps.js sets up a daily schedule only when invoked and honors the schedule opt-out., dist/server/sleep-offload.js spawns a package-owned child process to run memory consolidation with a timeout., dist/postinstall.js describes its Claude configuration check as read-only and directs users to run hippo init for setup.

L79: }
L80: export function buildDailyRunnerCommand(projectDir, platform = process.platform) {
