## 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:** 1.4.50
- **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 flagged agent integration behavior is tied to explicit EchoMem setup and local session processing, while the manifest has no install-time trigger. The inspected authentication code directs authenticated requests to the configured EchoMem API base URL.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%

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 surface was identified in the inspected source.

- **Trigger:** The agent hook configuration is written through the CLI setup flow, rather than an npm install hook.

- **Impact:** No unconsented install-time control-surface change, credential theft, or unrelated account action was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T01:44:05.690Z

### AI review details

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

- **Mechanism:** That flow adds EchoMem session and checkpoint commands to detected agent configurations; the other flagged locations read local session metadata or identify project paths.

- **Rationale:** The flagged agent integration behavior is tied to explicit EchoMem setup and local session processing, while the manifest has no install-time trigger. The inspected authentication code directs authenticated requests to the configured EchoMem API base URL.

- **Files touched:** package.json, assets/canonical-scorer/analyze-10-problems.mjs, assets/canonical-scorer/optimizable\_detail.mjs, dist/hud/hooks.js, dist/hud/monitor.js, dist/migrate.js, dist/setup.js, dist/durable-entry.js, dist/hud/server.js

### 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 identifies the package entrypoint and has no npm install lifecycle hook; its packaging hook is prepack., Two bundled scorer utilities locate local Codex session files, while the monitor reads session metadata and migration code recognizes Claude project paths., The setup flow installs EchoMem session hooks for detected clients when its CLI setup flow runs; the hooks invoke this package’s own local commands., The default API host is EchoMem’s configured service, and authenticated requests use that same API base URL.
