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. The package performs authenticated cloud and local CLI operations only when its SDK or CLI is invoked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-12T15:37:45.427Z - **Finished:** 2026-09-12T15:38:43.820Z - **Download time:** 255 ms - **Static scan time:** 3421 ms - **AI review time:** 54716 ms - **Total time:** 58393 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. The package performs authenticated cloud and local CLI operations only when its SDK or CLI is invoked. - **Trigger:** Explicit SDK or CLI use. - **Impact:** User-requested sandbox, cloud, and filesystem operations may occur. - **Review source:** ai\_review - **Reviewed:** 2026-09-12T15:38:43.820Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated Tensorlake API calls and local Tensorlake CLI invocation. - **Rationale:** The static signals correspond to normal cloud-SDK capabilities and explicit local CLI integration. There is no install-time trigger or concrete malicious behavior in the inspected source. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **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 exposes SDK and CLI entrypoints but contains no install lifecycle hook., The flagged child-process code runs a selected local Tensorlake CLI only during mount operations and separates caller paths from flags., The applications bundle uses configured Tensorlake endpoints and credentials only when an explicit sandbox-image operation runs. - **Evidence against:** No preinstall, install, or postinstall script is present., No evidence of import-time execution, secret harvesting, foreign configuration mutation, or hidden exfiltration was found., Network and native functionality are consistent with an authenticated cloud and sandbox SDK. ## Affected versions and remediation This report applies to tensorlake@0.5.132. - Review the evidence and your use of tensorlake@0.5.132 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.
