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 did not substantiate the scanner's credential-redirection or command-output-exfiltration claims. The install hook performs checksum-verified vendor binary setup, and the flagged agent locations show ordinary configuration and runtime behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-09T08:52:58.175Z - **Finished:** 2026-10-09T08:54:06.096Z - **Download time:** 512 ms - **Static scan time:** 16308 ms - **AI review time:** 51099 ms - **Total time:** 67921 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 downloads vendor binaries into the package's state directory and verifies their checksums. - **Trigger:** npm postinstall runs the two package-local installers. - **Impact:** No confirmed credential theft, command-output exfiltration, or agent control-surface mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T08:54:06.096Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installers fetch platform-specific binaries from vendor release URLs and verify them against pinned SHA-256 values before saving them. - **Rationale:** Source inspection did not substantiate the scanner's credential-redirection or command-output-exfiltration claims. The install hook performs checksum-verified vendor binary setup, and the flagged agent locations show ordinary configuration and runtime behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json routes the postinstall hook to two package-local binary installers; the browser installer downloads from its vendor release and verifies a fixed SHA-256 checksum before saving the binary., The flagged agent-integration offsets resolve to ordinary package behavior: auth-file path helpers, prompt batching, rollout-file writing, trusted workspace roots, and registry rollout storage., The browser runtime uses a capability header for requests to a local loopback service; the runtime helper bundle exports model and context constants., The main bundle sets a DeepSeek API URL for cron prompt summaries, and the MCP client sends a configured token to its configured URL; inspected source does not establish an unrelated credential recipient. - **Evidence against:** The automatic postinstall downloads executable binaries, but the inspected browser installer pins a vendor release and rejects checksum mismatches; no broad project or agent-configuration mutation was found in the installer source., Scanner claims of credential redirection and command-output exfiltration were not substantiated by the inspected source excerpts. ## Affected versions and remediation This report applies to negotium@0.6.15. - Review the evidence and your use of negotium@0.6.15 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.
