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 scanner’s install-time and credential-related signals warrant review, but inspected source shows checksum-verified, package-aligned binary setup and no concrete attack chain. The flagged agent-integration locations do not establish exfiltration or unconsented control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-09T08:53:38.504Z - **Finished:** 2026-10-09T08:54:41.837Z - **Download time:** 4408 ms - **Static scan time:** 17478 ms - **AI review time:** 41445 ms - **Total time:** 63333 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 postinstall hook downloads version-pinned platform binaries and verifies their checksums before placing them in Negotium’s state directory. - **Trigger:** npm postinstall. - **Impact:** The inspected behavior installs Negotium runtime tools; no concrete consumer-project mutation, credential exfiltration, or agent-control hijack was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T08:54:41.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook selects a platform asset from a fixed release and checks its SHA-256 before replacing a binary in the package’s state directory. - **Rationale:** The scanner’s install-time and credential-related signals warrant review, but inspected source shows checksum-verified, package-aligned binary setup and no concrete attack chain. The flagged agent-integration locations do not establish exfiltration or unconsented control-surface mutation. - **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, ~/.negotium/binaries/browser-rs/, ~/.negotium/binaries/bash-rs/ - **Network endpoints:** github.com ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs two named binary installers from its postinstall hook., Both installers use platform-specific release assets and pinned SHA-256 values, and place binaries under Negotium’s state directory., The requested agent-integration locations resolve to auth-path helpers, scoped environment setup, or Claude session-file handling; inspected excerpts show no credential forwarding to an unrelated recipient., The flagged runtime bundle excerpts identify ordinary logger and browser-process modules; no concrete attack behavior was established. - **Evidence against:** The postinstall hook downloads and installs executable binaries, but the inspected scripts pin release versions, verify checksums, and target Negotium’s own binary directory., The package exposes credential-path and agent runtime functionality, but the inspected target excerpts do not show unconsented agent-control configuration changes or credential exfiltration. ## Affected versions and remediation This report applies to negotium@0.21.2. - Review the evidence and your use of negotium@0.21.2 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.
