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 install-time binary bootstrap is transparent, package-aligned, and integrity-pinned. Direct inspection did not substantiate the scanner's claims of credential redirection, foreign-package overwrite, or command-output exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-23T06:57:33.183Z - **Finished:** 2026-08-23T06:59:02.184Z - **Download time:** 763 ms - **Static scan time:** 18645 ms - **AI review time:** 69591 ms - **Total time:** 89001 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:** Installation downloads two package-aligned native helper binaries, verifies pinned hashes, and stores them under Negotium state. No confirmed malicious attack surface was found. - **Trigger:** npm postinstall - **Impact:** Installs browser-rs and bash-rs helpers for later explicit runtime use. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/mcp-factories.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T06:59:02.184Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified first-party native helper bootstrap - **Rationale:** The install-time binary bootstrap is transparent, package-aligned, and integrity-pinned. Direct inspection did not substantiate the scanner's claims of credential redirection, foreign-package overwrite, or command-output exfiltration. - **Files touched:** package.json, 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:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.23, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.7 ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** postinstall runs two native-tool installer scripts., Installers download executable release assets during install. - **Evidence against:** Each downloaded asset is checked against a hardcoded SHA-256 before installation., Writes are confined to Negotium's own .negotium binary directory; no foreign agent configuration is changed., The reviewed peer bridge accepts only loopback URLs., No source evidence of credential exfiltration, remote payload execution, or destructive behavior. ## Affected versions and remediation This report applies to negotium@0.5.16. - Review the evidence and your use of negotium@0.5.16 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.
