Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected postinstall source shows fixed, named file-copy behavior and does not identify the PDF as a target. However, the PDF is shipped and its available analysis leaves its structure and executable behavior unresolved, so manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-19T04:30:53.189Z - **Finished:** 2026-10-19T04:31:22.911Z - **Download time:** 1277 ms - **Static scan time:** 103 ms - **AI review time:** 28340 ms - **Total time:** 29722 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 shipped PDF remains unresolved because its structure and executable behavior could not be analyzed. - **Trigger:** Package installation runs the postinstall hook; the PDF’s own activation is unknown. - **Impact:** Whether the PDF contains executable or otherwise relevant behavior remains unknown, so a clean verdict is not supported. - **Evidence paths:** .lpm-inspection-vJw7ad/0-163ed93a16b3.txt, package.json, src/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T04:31:22.911Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The manifest includes the asset directory, while the inspected hook copies only two explicitly named logos. The available artifact analysis could not determine the PDF’s contents or behavior. - **Rationale:** The inspected postinstall source shows fixed, named file-copy behavior and does not identify the PDF as a target. However, the PDF is shipped and its available analysis leaves its structure and executable behavior unresolved, so manual review is warranted. - **Files touched:** package.json, src/postinstall.js, assets/image/jews-support-a-free-palestine-poster.pdf ### Review decision - **Verdict:** Manual Review - **Confidence:** 94.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json includes assets/image/ and runs src/postinstall.js on postinstall., The postinstall asset copy list names only doikayt-logo.png and doikayt-logo.svg., The offline analysis reports that the PDF’s structure and executable behavior remain unresolved. - **Evidence against:** The inspected postinstall code copies a fixed list of config files, pipeline files, and two named logos; it does not identify the PDF as a copy target., No inspected source established execution or loading of the PDF. ## Affected versions and remediation This report applies to @doikayt/typescript-build-config@0.1.54. - Review the evidence and your use of @doikayt/typescript-build-config@0.1.54 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.
