Treat them as untrusted evidence. 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:** 0.0.2976 - **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 source shows no install lifecycle hook or concrete attack behavior. Because its runtime entrypoints load selected dependencies whose source could not be assessed, the package cannot be cleared from this snapshot. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-21T06:08:45.897Z - **Finished:** 2026-10-21T06:09:39.589Z - **Download time:** 1772 ms - **Static scan time:** 58 ms - **AI review time:** 51861 ms - **Total time:** 53692 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 package source. Runtime behavior remains unresolved because selected dependencies imported by the library and CLI could not be inspected. - **Trigger:** Importing the library or invoking its CLI loads the corresponding declared dependencies. - **Impact:** No concrete attack impact was established; the unavailable dependency behavior prevents a clean determination. - **Evidence paths:** package.json, dist/index.js, cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-21T06:09:39.589Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected entrypoints delegate runtime behavior to dependencies whose source was unavailable in the package snapshot. - **Rationale:** The inspected package source shows no install lifecycle hook or concrete attack behavior. Because its runtime entrypoints load selected dependencies whose source could not be assessed, the package cannot be cleared from this snapshot. ### Review decision - **Verdict:** Manual Review - **Confidence:** 79.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest points to dist/index.js as the library entry and declares @tscircuit/core and @tscircuit/eval as dependencies., The library entry re-exports @tscircuit/core and @tscircuit/eval, so those packages are loaded through the runtime entry., The CLI entrypoint imports @tscircuit/cli when invoked., The selected core, eval, and CLI dependency source was unresolved or unavailable in the inspected package snapshot, so their runtime behavior could not be assessed. - **Evidence against:** The inspected manifest lists no preinstall, install, or postinstall script., The inspected @tscircuit/props manifest contains build and maintenance scripts, with no install lifecycle script shown., The inspected React entry selects its development or production module based on NODE\_ENV. ## Affected versions and remediation This report applies to tscircuit@0.0.2976. - Review the evidence and your use of tscircuit@0.0.2976 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.
