Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Direct inspection found a math library manifest and re-export entrypoint, with no install hooks or source evidence of execution, harvesting, exfiltration, persistence, or destructive behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 98.0% - **Started:** 2026-08-25T15:42:23.185Z - **Finished:** 2026-08-25T15:42:59.705Z - **Download time:** 505 ms - **Static scan time:** 307 ms - **AI review time:** 35708 ms - **Total time:** 36520 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 surface. The package exposes local matrix and linear-algebra APIs without lifecycle execution or risky host interactions. - **Trigger:** User imports the package and invokes its exported math APIs. - **Impact:** No malicious behavior established. - **Evidence paths:** package.json, src/index.js, matrix.js, matrix.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T15:42:59.705Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local matrix computation and re-exports. - **Rationale:** Direct inspection found a math library manifest and re-export entrypoint, with no install hooks or source evidence of execution, harvesting, exfiltration, persistence, or destructive behavior. - **Files touched:** package.json, src/index.js, matrix.js, matrix.mjs ### Review decision - **Verdict:** Clean - **Confidence:** 98.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Manifest has no preinstall, install, or postinstall hook., Entrypoint only re-exports matrix and decomposition APIs., Source scan found no filesystem, process, network, shell, eval, or credential-harvesting primitives. ## Affected versions and remediation This report applies to matrixflow-js@3.2.2. - Review the evidence and your use of matrixflow-js@3.2.2 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.
