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 reviewed entrypoints and available dependency excerpts establish no concrete attack, but source for selected runtime dependencies including @tscircuit/core and @tscircuit/cli was unavailable. This unresolved execution path requires manual review rather than a clean or malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-22T05:43:54.903Z - **Finished:** 2026-10-22T05:44:36.965Z - **Download time:** 2067 ms - **Static scan time:** 52 ms - **AI review time:** 39942 ms - **Total time:** 42062 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 concrete attack was identified in the inspected package code. Important runtime dependencies used by the library and CLI could not be reviewed, leaving their behavior unresolved. - **Trigger:** Importing the library or invoking its CLI loads the corresponding runtime dependencies. - **Impact:** The package cannot be cleared as clean from the inspected source because behavior in those dependencies remains unverified. - **Evidence paths:** package.json, cli.mjs, dist/index.js, .lpm-dependency-evidence-761e2b72-ad99-4d72-8205-c547e3179e6c/3/npm-linux/dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T05:44:36.965Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The library re-exports core and evaluation dependencies, while the CLI imports its command package; source for those dependencies was unavailable. - **Rationale:** The reviewed entrypoints and available dependency excerpts establish no concrete attack, but source for selected runtime dependencies including @tscircuit/core and @tscircuit/cli was unavailable. This unresolved execution path requires manual review rather than a clean or malicious verdict. - **Files touched:** package.json, cli.mjs, dist/index.js, .lpm-dependency-evidence-761e2b72-ad99-4d72-8205-c547e3179e6c/3/npm-linux/dist/index.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 87.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest points to dist/index.js and declares no install lifecycle hook., The CLI sets a package-local browser bundle path only when the environment variable is unset, then imports @tscircuit/cli., The library entrypoint exports from @tscircuit/core and @tscircuit/eval; source for these dependencies was unavailable for this review., The inspected @tscircuit/props bundle begins with type checks and component property definitions; the inspected React entrypoint selects its production or development build. ## Affected versions and remediation This report applies to tscircuit@0.0.3000. - Review the evidence and your use of tscircuit@0.0.3000 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.
