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 source shows a postinstall hook and ordinary configuration setup, while the Playwright entry configures a Chromium path. The included PDF could not be structurally inspected, so its behavior remains unresolved and requires manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-13T04:46:47.872Z - **Finished:** 2026-10-13T04:55:29.504Z - **Download time:** 2550 ms - **Static scan time:** 101 ms - **AI review time:** 518979 ms - **Total time:** 521632 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 in the inspected executable source. The included PDF remains unresolved because offline analysis could not inspect its structure. - **Trigger:** Package installation invokes the postinstall script. - **Impact:** The available source does not establish a harmful effect, but the unresolved artifact prevents ruling one out. - **Evidence paths:** assets/image/jews-support-a-free-palestine-poster.pdf, .lpm-inspection-w49XYz/0-163ed93a16b3.txt, src/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-13T04:55:29.504Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected hook copies configuration and named assets; the PDF is not in its asset-copy list. Its contents remain unexamined. - **Rationale:** The inspected source shows a postinstall hook and ordinary configuration setup, while the Playwright entry configures a Chromium path. The included PDF could not be structurally inspected, so its behavior remains unresolved and requires manual review. - **Files touched:** src/postinstall.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 76.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs src/postinstall.js during installation and includes assets/image/ in the package., The postinstall asset-copy list names only the two logo files; the PDF is not named there., The offline analysis could not structurally inspect the PDF, leaving its behavior unresolved., src/playwright.js uses the configured or discovered Chromium executable path to build launch options. - **Evidence against:** The inspected postinstall asset-copy list does not include the PDF., The inspected Playwright code configures Chromium launch options; it does not show a malicious action. ## Affected versions and remediation This report applies to @doikayt/typescript-build-config@0.1.38. - Review the evidence and your use of @doikayt/typescript-build-config@0.1.38 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.
