Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The install hook executes test.js, which only self-imports and calls absent exports inside a catch block. - **Trigger:** npm postinstall - **Impact:** At most a caught runtime error written to stderr; no file, network, or process action is present. - **Evidence paths:** package.json, test.js, readme.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T07:45:09.211Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Nonfunctional self-require and caught function calls - **Rationale:** Direct inspection found a broken postinstall hook but no concrete harmful behavior. Dependency names and lifecycle presence are insufficient to establish malicious intent. - **Files touched:** package.json, test.js ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines postinstall: node test.js., package.json lists child\_process and os dependencies, but no package source imports them. - **Evidence against:** test.js is the only executable source and contains no network, filesystem, shell, eval, or environment access., During postinstall, test.js self-requires the package, obtains no declared exports, and catches the resulting call error., No source contains credential collection, payload download, persistence, or destructive operations. ## Affected versions and remediation This report applies to app-data-layer@2.1.6. - Avoid installing app-data-layer@2.1.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
