Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed attack was identified. Inspected install behavior builds package-owned server artifacts, and the flagged agent locations perform executable discovery and workflow checkpoint storage. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-05T04:36:00.106Z - **Finished:** 2026-10-05T04:38:02.549Z - **Download time:** 2558 ms - **Static scan time:** 9659 ms - **AI review time:** 110225 ms - **Total time:** 122443 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 confirmed attack was identified. Inspected install behavior builds package-owned server artifacts, and the flagged agent locations perform executable discovery and workflow checkpoint storage. - **Trigger:** npm installation runs the local build hook; explicit CLI commands activate server and installer functionality. - **Impact:** The inspected behavior supports the workbench and terminal features without establishing credential theft or unconsented agent control changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-05T04:38:02.549Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Bundled code is compiled and cached locally; workflow operations persist JSON state rather than agent control settings. - **Rationale:** The scanner's agent-control and source-similarity labels are not substantiated by the inspected behavior: the flagged locations implement workflow storage, executable discovery, and terminal plumbing. The install hook performs a local package-owned build, with no concrete malicious chain established. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** package.json runs dist/postinstall.js; runtime dependencies contain no self-dependency., dist/postinstall.js compiles bundled server code with Bun into the versioned .cxu/server cache., The flagged dist/cli.js location searches for the Codex executable; installer execution requires explicit CLI consent., The flagged dist/index.js location stores JSON workflow checkpoints under .codex/sa-vm/split-workflows, without changing agent instructions or configuration., Both flagged node-pty files implement native terminal process creation and local terminal communication. ## Affected versions and remediation This report applies to @codex-ultra/cxu@0.2.104. - Review the evidence and your use of @codex-ultra/cxu@0.2.104 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.
