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 package source shows no install hook and makes its reporting integrations explicit CLI choices. The Datadog client is a selected runtime dependency whose source was absent from the extracted snapshot, 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:** 91.0% - **Started:** 2026-10-23T13:29:52.192Z - **Finished:** 2026-10-23T13:30:57.458Z - **Download time:** 4832 ms - **Static scan time:** 128 ms - **AI review time:** 60306 ms - **Total time:** 65266 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 package-owned attack behavior was confirmed. The declared Datadog client dependency was unavailable for source inspection, leaving its behavior unresolved. - **Trigger:** Installing the package may activate dependency lifecycle behavior; selecting --datadog also loads the client at runtime. - **Impact:** No attack is established, but the unresolved dependency prevents clearing the package for publication. - **Evidence paths:** package.json, dist/cli.js, dist/interfaces/datadog.js - **Review source:** ai\_review - **Reviewed:** 2026-10-23T13:30:57.458Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package declares the Datadog client and uses it to submit benchmark metrics, but the dependency source could not be reviewed. - **Rationale:** The inspected package source shows no install hook and makes its reporting integrations explicit CLI choices. The Datadog client is a selected runtime dependency whose source was absent from the extracted snapshot, so its behavior remains unresolved and requires manual review. ### Review decision - **Verdict:** Manual Review - **Confidence:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json lists only lint, test, and build scripts; it defines no lifecycle hook., The Datadog client is a runtime dependency, and the CLI loads its reporter only when --datadog is selected., The Datadog reporter submits benchmark metrics through that client., The Snowflake reporter is exposed as an explicit CLI option and sends records to its configured batch URI. - **Evidence against:** The Datadog dependency source was not present in the extracted dependency snapshot, so its install-time and runtime behavior could not be reviewed. ## Affected versions and remediation This report applies to @vercel/devlow-bench@16.4.3. - Review the evidence and your use of @vercel/devlow-bench@16.4.3 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.
