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 entrypoints show no concrete attack behavior, but delegate important CLI and runtime behavior to dependencies whose source was unavailable. This unresolved selected dependency source prevents a clean verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-22T05:27:21.936Z - **Finished:** 2026-10-22T05:28:25.150Z - **Download time:** 3558 ms - **Static scan time:** 59 ms - **AI review time:** 59596 ms - **Total time:** 63214 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 attack behavior was identified in the inspected entrypoints. The CLI and main runtime delegate to dependencies whose source was unavailable, leaving their behavior unresolved. - **Trigger:** Running the CLI or importing the main package entrypoint. - **Impact:** The available source does not establish an attack, but the unresolved dependency behavior prevents a clean determination. - **Evidence paths:** cli.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T05:28:25.150Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI dynamically imports @tscircuit/cli, while the main entrypoint re-exports @tscircuit/core and @tscircuit/eval. - **Rationale:** The inspected package entrypoints show no concrete attack behavior, but delegate important CLI and runtime behavior to dependencies whose source was unavailable. This unresolved selected dependency source prevents a clean verdict. ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The CLI entrypoint imports @tscircuit/cli, whose source was not present in the inspected snapshot., The main entrypoint re-exports @tscircuit/core and @tscircuit/eval; the core dependency source was unresolved., The inspected props dependency contains component type definitions, and the React entrypoint selects its standard development or production implementation. ## Affected versions and remediation This report applies to tscircuit@0.0.2999. - Review the evidence and your use of tscircuit@0.0.2999 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.
