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 hint. The manifest has no install lifecycle hook, and the reviewed runtime and dependency code supports the package's analysis and graph-formatting functions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-20T16:02:15.037Z - **Finished:** 2026-10-20T16:05:02.520Z - **Download time:** 1276 ms - **Static scan time:** 5744 ms - **AI review time:** 160462 ms - **Total time:** 167483 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 surface was identified in the inspected source. The flagged process execution is tied to a selected analyzer mode or a repository-analysis helper. - **Trigger:** The CLI runs when a user invokes it; its OpenAPI runtime branch is selected with the openapi-runtime format. - **Impact:** No malicious effect was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T16:05:02.520Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The manifest has no install hook, and inspected runtime code performs analysis and graph formatting. No credential transfer or package-selected gateway was found. - **Rationale:** Source inspection did not substantiate the scanner's credential-redirection hint. The manifest has no install lifecycle hook, and the reviewed runtime and dependency code supports the package's analysis and graph-formatting functions. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes an analyzer CLI and contains no install lifecycle hook. The inspected runtime and dependency sources implement code analysis, graph conversion and layout, and schema handling; the CLI's subprocess branch is limited to the explicitly selected openapi-runtime mode. ## Affected versions and remediation This report applies to effect-analyzer@3.9.1. - Review the evidence and your use of effect-analyzer@3.9.1 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.
