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 subprocess capabilities are SDK and explicitly invoked CLI features, not install-time behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-09T09:32:18.205Z - **Finished:** 2026-09-09T09:33:28.703Z - **Download time:** 507 ms - **Static scan time:** 6139 ms - **AI review time:** 63851 ms - **Total time:** 70498 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 subprocess capabilities are SDK and explicitly invoked CLI features, not install-time behavior. - **Trigger:** A user creates a cloud client, deploys an application, or calls a filesystem mount method. - **Impact:** These operations can act on the user's configured Tensorlake resources, but no unconsented local mutation or exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-09T09:33:28.703Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated Tensorlake API requests and user-invoked Tensorlake CLI execution. - **Rationale:** The static signals are explained by an SDK for cloud sandbox operations. Its manifest has no install hooks or self-dependency, and inspected command execution is reachable through explicit runtime features. - **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:** No install lifecycle hook is declared in the manifest., The SDK reads its API key from a named environment variable and uses it as an authorization header for its configured API client., The flagged child-process use runs a discovered Tensorlake CLI only after a mount operation calls it., The deployment binary only delegates an explicit command to a locally installed Python module. - **Evidence against:** No credential harvesting, hidden exfiltration, remote code download, or persistence behavior was found in the inspected sources., The only default network hosts are Tensorlake service endpoints, consistent with the SDK's cloud and sandbox functions., There is no runtime dependency on tensorlake itself. ## Affected versions and remediation This report applies to tensorlake@0.5.128. - Review the evidence and your use of tensorlake@0.5.128 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.
