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 JavaScript supports ordinary project setup and does not establish an attack. The shipped PDF’s structure and behavior remain unresolved, so the source does not support a clean verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-14T03:07:21.158Z - **Finished:** 2026-10-14T03:08:12.840Z - **Download time:** 780 ms - **Static scan time:** 90 ms - **AI review time:** 50810 ms - **Total time:** 51682 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 confirmed in the inspected JavaScript. The install hook performs project setup, but the shipped PDF could not be resolved as inert data or executable content. - **Trigger:** Package installation triggers the postinstall hook. - **Impact:** No malicious impact is established; the unresolved PDF prevents a clean determination. - **Evidence paths:** package.json, src/postinstall.js, assets/image/jews-support-a-free-palestine-poster.pdf, .lpm-inspection-dlAARv/0-163ed93a16b3.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-14T03:08:12.840Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies fixed configuration, pipeline, and logo files; the flagged PDF is not in its asset copy list. Its structure remains unresolved. - **Rationale:** The inspected JavaScript supports ordinary project setup and does not establish an attack. The shipped PDF’s structure and behavior remain unresolved, so the source does not support a clean verdict. - **Files touched:** docs/assets/doikayt-logo.png, docs/assets/doikayt-logo.svg ### Review decision - **Verdict:** Manual Review - **Confidence:** 82.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** High - **AI review observations:** The manifest runs src/postinstall.js during installation., The postinstall asset list copies only the package’s two logo files into docs/assets; it does not list the flagged PDF., The Playwright helper uses a shell command only to locate Chromium on PATH., The trusted offline analysis identifies the PDF format but reports that its structure and executable behavior remain unresolved. - **Evidence against:** Inspected JavaScript shows configuration scaffolding and fixed asset copies, with no confirmed malicious behavior. ## Affected versions and remediation This report applies to @doikayt/typescript-build-config@0.1.43. - Review the evidence and your use of @doikayt/typescript-build-config@0.1.43 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.
