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 sends UI activity and embedding metadata to the vendor’s telemetry service, and the package README does not disclose this behavior. This is undisclosed runtime telemetry, so warn rather than block; the oversized bundle could not be cited because the citation service rejected sources over its 16 MiB verification limit. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-29T20:10:11.355Z - **Finished:** 2026-10-29T20:11:30.875Z - **Download time:** 2839 ms - **Static scan time:** 62 ms - **AI review time:** 76619 ms - **Total time:** 79520 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:** Undocumented runtime telemetry in the browser UI reports runframe activity to the package vendor. - **Trigger:** When the browser bundle is loaded and runframe UI activity changes. - **Impact:** The vendor receives usage and embedding metadata without clear package documentation or an explicit opt-in. - **Evidence paths:** dist/browser.min.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:11:30.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle initializes telemetry and sends runframe\_activity events with UI properties and an embed domain or anonymous ID to https://postpig.tscircuit.com. A global TSCIRCUIT\_TELEMETRY\_DISABLED setting can disable it. - **Rationale:** The browser bundle automatically sends UI activity and embedding metadata to the vendor’s telemetry service, and the package README does not disclose this behavior. This is undisclosed runtime telemetry, so warn rather than block; the oversized bundle could not be cited because the citation service rejected sources over its 16 MiB verification limit. - **Files touched:** dist/browser.min.js - **Network endpoints:** https://postpig.tscircuit.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The browser bundle initializes telemetry automatically and captures runframe activity events to https://postpig.tscircuit.com., Captured event properties include source, component, embedded status, and active tab; the payload also includes an embed domain or anonymous ID., Telemetry can be disabled with TSCIRCUIT\_TELEMETRY\_DISABLED, but the package README does not document the telemetry., The package exports dist/browser.min.js as its browser entry point. - **Evidence against:** The package is a circuit design toolkit, and the observed events appear to describe UI activity rather than credentials or file contents., The telemetry code suppresses collection on localhost unless a CLI-specific flag is enabled., The CLI imports @tscircuit/cli when the published executable runs; no lifecycle scripts are declared. ## Affected versions and remediation This report applies to tscircuit@0.0.3035. - Review the evidence and your use of tscircuit@0.0.3035 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.
