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.

A clean verdict cannot be grounded. ### Review decision - **Verdict:** Manual Review - **Confidence:** 50.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs a postinstall setup script; it also declares the package’s config and asset files., The hook skips configuration when the project package file is absent or when the project is this package itself., It copies a fixed set of starter configuration files only when none already exist., Asset handling names only the two logo files; the inspected source does not reference the poster., The Playwright helper finds a local Chromium executable and returns it as Playwright’s launch path., The offline analysis identifies the poster as an unrecognized artifact, and no inspected source path loads or executes it. ## Affected versions and remediation This report applies to @doikayt/typescript-build-config@0.1.53. - Review the evidence and your use of @doikayt/typescript-build-config@0.1.53 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** src/playwright.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = @doikayt/typescript-build-config@0.1.14 matchedPath = src/playwright.js matchedIdentity = npm:[redacted]:0.1.14 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 11. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 50.0% - **Path:** package.json - **Public source:** [View source]() package.json runs a postinstall setup script; it also declares the package’s config and asset files.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 50.0% - **Path:** src/postinstall.js - **Public source:** [View source]() The hook skips configuration when the project package file is absent or when the project is this package itself. Public source snippet (untrusted): ```javascript t has a package.json) — nothing to configure. Postinstall is // warn-only, so no-op instead of crashing. if (!existsSync(projectPkgPath)) { console.warn( `${PREFIX} WARNING: no package.json in ${projectRoot} — nothing to configure.
