Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 0.0.2991 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 and prepared dependency files show ordinary entry wiring and no concrete attack behavior. The active CLI, core, and eval dependency sources remain unresolved, so the package cannot be cleared from this source snapshot. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 80.0% - **Started:** 2026-10-22T07:05:57.608Z - **Finished:** 2026-10-22T07:06:48.561Z - **Download time:** 1545 ms - **Static scan time:** 57 ms - **AI review time:** 49350 ms - **Total time:** 50953 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 source. Assessment remains unresolved because active entrypoints reach dependencies whose source was unavailable for inspection. - **Trigger:** Importing the package runtime entry or invoking its CLI. - **Impact:** Behavior reached through those dependencies cannot be assessed from the inspected files. - **Evidence paths:** package.json, cli.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T07:06:48.561Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime entry re-exports core and eval functionality, while the CLI imports the separate CLI dependency; their selected source was unavailable in this snapshot. - **Rationale:** The inspected package and prepared dependency files show ordinary entry wiring and no concrete attack behavior. The active CLI, core, and eval dependency sources remain unresolved, so the package cannot be cleared from this source snapshot. - **Files touched:** package.json, cli.mjs, dist/index.js, .lpm-dependency-evidence-afe834d4-d3e8-43f4-9901-a68f5dd43eec/3/npm-linux/package.json, .lpm-dependency-evidence-afe834d4-d3e8-43f4-9901-a68f5dd43eec/3/npm-linux/dist/index.js, .lpm-dependency-evidence-afe834d4-d3e8-43f4-9901-a68f5dd43eec/4/npm-linux/package.json, .lpm-dependency-evidence-afe834d4-d3e8-43f4-9901-a68f5dd43eec/4/npm-linux/index.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 80.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The CLI entry imports @tscircuit/cli, and the package runtime entry re-exports @tscircuit/core and @tscircuit/eval; these selected dependency sources remain unresolved in the inspected snapshot., The inspected @tscircuit/props entry contains schema definitions, and the React entry selects its development or production module. ## Affected versions and remediation This report applies to tscircuit@0.0.2991. - Review the evidence and your use of tscircuit@0.0.2991 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.
