## 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:** 2.1.0
- **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 postinstall behavior is limited to setup guidance and repair of a Codex wrapper already recorded as opted in. Agent integration and daily scheduling occur through the explicit init command, so the inspected scanner signals do not establish malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-16T11:24:07.466Z
- **Finished:** 2026-10-16T11:25:08.945Z
- **Download time:** 763 ms
- **Static scan time:** 3415 ms
- **AI review time:** 57299 ms
- **Total time:** 61479 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 behavior was identified. The install hook offers opt-in instructions and repairs only a previously installed Codex wrapper.

- **Trigger:** Package installation triggers the postinstall module; running hippo init triggers integrations and daily scheduling.

- **Impact:** No unconsented data transfer, harmful mutation, or other confirmed attack effect was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-16T11:25:08.945Z

### AI review details

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

- **Mechanism:** Postinstall checks installed-agent state and prints setup guidance. The init command performs integrations and scheduling, with skip options available.

- **Rationale:** The postinstall behavior is limited to setup guidance and repair of a Codex wrapper already recorded as opted in. Agent integration and daily scheduling occur through the explicit init command, so the inspected scanner signals do not establish malicious behavior.

- **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli/init.js, dist/hooks/codex-wrapper.js, dist/capture/compaction-spool.js, dist/cli/install-steps.js

### 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 declares a postinstall hook that runs scripts/postinstall.cjs., The postinstall module checks for existing agent installations, prints setup instructions, and only repairs a Codex wrapper when prior opt-in metadata exists., The init command detects project agent files before adding integrations; its Codex integration offers an install command, while other hooks are installed through init., The compaction spool uses local files to store and replay compaction summaries., Daily scheduling is initiated by hippo init and can be skipped with --no-schedule or HIPPO\_SKIP\_SCHEDULE=1.

- **Evidence against:** The package has a postinstall lifecycle hook that imports dist/postinstall.js., The init flow can write agent configuration and create a daily schedule, but those actions are tied to an explicit CLI command.
