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 a postinstall binary setup that uses pinned release assets and checksum validation, plus local agent authentication and session handling. The scanner’s credential-redirection signal corresponds to local Codex auth-path resolution; no credential transfer or other concrete attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-20T08:29:18.391Z - **Finished:** 2026-10-20T08:30:38.821Z - **Download time:** 1286 ms - **Static scan time:** 17565 ms - **AI review time:** 61578 ms - **Total time:** 80430 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 retrieves versioned binaries and verifies their checksums before placing them in Negotium’s state directory. - **Trigger:** Package installation triggers the postinstall script; agent and query code runs when invoked through the package runtime. - **Impact:** The inspected behavior supports the package’s binary setup and agent runtime; no confirmed malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T08:30:38.821Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installers fetch platform assets from the project’s GitHub releases and reject content that fails the pinned SHA-256 check. Flagged credential and agent locations resolve local auth state or handle session files; no unrelated credential recipient was found. - **Rationale:** Source inspection found a postinstall binary setup that uses pinned release assets and checksum validation, plus local agent authentication and session handling. The scanner’s credential-redirection signal corresponds to local Codex auth-path resolution; no credential transfer or other concrete attack was identified. - **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, dist/registry.js, dist/chunk-bn1tt2qw.js - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/, https://github.com/maestrojeong/bash-rs-mcp/releases/download/ ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json activates two binary installers; each fetches a fixed release asset and checks its SHA-256 before installation., Both installers place binaries under the Negotium state directory., The flagged Codex auth helper resolves a local auth-file path; the auth check tests whether that file exists., The flagged agent and registry code writes session rollout files to the user’s Claude projects directory., The flagged query runtime initializes a standard stderr logger; the remaining flagged bundle locations contain local auth-path resolution or agent runtime setup. - **Evidence against:** The postinstall downloads executable binaries, but the inspected installer code pins release versions and rejects checksum mismatches., The reviewed credential-related code does not show a transfer to an unofficial gateway or other recipient. ## Affected versions and remediation This report applies to negotium@0.22.2. - Review the evidence and your use of negotium@0.22.2 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. ## Public findings ### 1.
