This report does not record a matching static-policy override reason. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface was established. Network and local CLI behavior is exposed through SDK operations rather than package installation or import. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-07T23:14:45.992Z - **Finished:** 2026-09-07T23:15:45.327Z - **Download time:** 506 ms - **Static scan time:** 5526 ms - **AI review time:** 53303 ms - **Total time:** 59335 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 malicious attack surface was established. Network and local CLI behavior is exposed through SDK operations rather than package installation or import. - **Trigger:** Explicit SDK calls that use cloud services or filesystem mounts. - **Impact:** No unconsented install-time execution, data harvesting, persistence, or destructive behavior was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-07T23:15:45.327Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked API requests and local CLI execution. - **Rationale:** The flagged network, environment, and child-process primitives are consistent with an SDK for cloud sandboxes and filesystem mounts. Source inspection found no lifecycle hook, self-dependency, hidden payload, or concrete malicious behavior. - **Network endpoints:** api.tensorlake.ai, sandbox.tensorlake.ai ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason. - **Evidence for AI clean decision:** The manifest defines build, test, lint, and prepack scripts but no install lifecycle hook., The application bundle uses configured Tensorlake API and sandbox endpoints with an optional API key., The application bundle invokes the local Tensorlake CLI only through explicit filesystem mount methods and separates user paths after an end-of-options marker., The main bundle uses execFile with an argument array rather than a shell command string. - **Evidence against:** The SDK can send authenticated requests to Tensorlake services when its API methods are used., Mount operations can execute a locally installed Tensorlake CLI at runtime. ## Affected versions and remediation This report applies to tensorlake@0.5.127. - Review the evidence and your use of tensorlake@0.5.127 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.
