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 usage telemetry to the package vendor and may include the embedding domain as an identifying detail. This merits a warning under the runtime telemetry rules; no malicious credential theft or unrelated collection was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-01T16:18:50.344Z - **Finished:** 2026-11-01T16:20:20.493Z - **Download time:** 10002 ms - **Static scan time:** 58 ms - **AI review time:** 80088 ms - **Total time:** 90149 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 browser runtime telemetry reports embedding-domain or anonymous identifiers and activity to the package vendor. - **Trigger:** Loading the ./browser bundle in a browser, except on localhost or when TSCIRCUIT\_TELEMETRY\_DISABLED is enabled. - **Impact:** The vendor receives identifying domain or anonymous usage telemetry without an evident consent prompt. - **Evidence paths:** dist/browser.min.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T16:20:20.493Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle initializes PostHog against https://postpig.tscircuit.com and captures runframe activity with the embedding domain or a persistent anonymous ID. - **Rationale:** The browser bundle automatically sends usage telemetry to the package vendor and may include the embedding domain as an identifying detail. This merits a warning under the runtime telemetry rules; no malicious credential theft or unrelated collection was identified. - **Files touched:** dist/browser.min.js - **Network endpoints:** https://postpig.tscircuit.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exports dist/browser.min.js as its ./browser entry., The browser bundle initializes telemetry to postpig.tscircuit.com on load, unless telemetry is disabled or the host is localhost., Telemetry identifies the embedding domain or uses a persistent anonymous ID, and the bundle captures runframe activity. - **Evidence against:** No install lifecycle scripts are declared., The main dist/index.js entry re-exports tscircuit libraries; the telemetry is in the separate browser bundle., No credential collection or unrelated data collector was identified. ## Affected versions and remediation This report applies to tscircuit@0.0.3048. - Review the evidence and your use of tscircuit@0.0.3048 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.
