Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 8 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.0.3032 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The browser bundle automatically reports runtime and circuit errors, and the package README does not disclose this telemetry. The opt-out setting reduces the risk, so this is suspicious runtime telemetry rather than a blockable attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-29T20:10:11.180Z - **Finished:** 2026-10-29T20:10:53.412Z - **Download time:** 1019 ms - **Static scan time:** 58 ms - **AI review time:** 41153 ms - **Total time:** 42232 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:** Undisclosed runtime error telemetry appears in the browser bundle. - **Trigger:** The UI renders an execution error or circuit JSON errors, unless telemetry is disabled through the global setting. - **Impact:** Runtime errors may be reported externally; the package provides a disable setting, but its README does not disclose the reporting. - **Evidence paths:** dist/browser.min.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:10:53.412Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle creates Error objects from error messages and stacks and passes them to \`Nq.captureException\`. - **Rationale:** The browser bundle automatically reports runtime and circuit errors, and the package README does not disclose this telemetry. The opt-out setting reduces the risk, so this is suspicious runtime telemetry rather than a blockable attack. ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The browser bundle automatically reports execution errors and circuit JSON errors through \`captureException\`., Reporting is skipped only when \`TSCIRCUIT\_TELEMETRY\_DISABLED\` is exactly \`true\`., The package README describes the circuit-design tool but does not disclose this error reporting. - **Evidence against:** The manifest declares no install, preinstall, or postinstall hook., The main entry re-exports circuit core and evaluation APIs., The CLI sets a standalone bundle path and imports the CLI package. ## Affected versions and remediation This report applies to tscircuit@0.0.3032. - Review the evidence and your use of tscircuit@0.0.3032 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 5. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 6. Medium: Oversized Source File - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** dist/webworker.min.js - **Public source:** [View source]() Package contains source files above the normal full-analysis size ceiling. Public source snippet (untrusted): ```javascript path = dist/webworker.min.js kind = oversized_source_file sizeBytes = 18241615 magicHex = [redacted] ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 76.0% - **Path:** README.md - **Public source:** [View source]() The package README describes the circuit-design tool but does not disclose this error reporting. Public source snippet (untrusted): ```markdown # tscircuit - React for Circuits **Design circuit boards with TypeScript and React.** tscircuit is an open-source electronics design tool.
