## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 18 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:** 0.5.17
- **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 download is a real but package-aligned capability: assets are platform-specific and hash-checked before execution. Source inspection found no concrete malicious chain or unconsented broad agent-control mutation.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 88.0%

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:** Install-time native-helper download is checksum-verified and limited to Negotium's own state directory. No confirmed credential exfiltration, remote payload execution, or foreign AI-agent control-surface mutation was found.

- **Trigger:** npm postinstall

- **Impact:** Installs executable helpers under the Negotium state directory.

- **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/mcp-factories.js, dist/runtime/src/agents/codex-native-multi-agent.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T13:53:50.244Z

### AI review details

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

- **Mechanism:** verified download of package-owned browser and shell helper binaries

- **Rationale:** The lifecycle download is a real but package-aligned capability: assets are platform-specific and hash-checked before execution. Source inspection found no concrete malicious chain or unconsented broad agent-control mutation.

- **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, ~/.negotium/binaries/browser-rs/v0.1.23/browser-rs, ~/.negotium/binaries/bash-rs/v0.1.7/bash-rs

- **Network endpoints:** github.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** Postinstall downloads platform-specific native helpers and makes them executable.

- **Evidence against:** Both downloaded helpers are pinned to GitHub release assets and verified against embedded SHA-256 hashes before installation., The lifecycle scripts only write under the package-owned Negotium state directory; no foreign AI-agent configuration is modified., Inspected MCP/Codex code uses an isolated temporary Codex home for cache refresh, then removes it; no credential redirect or fixed unofficial gateway was found.

## Affected versions and remediation

This report applies to negotium@0.5.17.

- Review the evidence and your use of negotium@0.5.17 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
