Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 9 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:** 0.0.3044 - **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 initializes runtime analytics by default outside localhost and reports activity and errors using an embedding-domain or anonymous identity. The source provides a disable flag but no clear user-facing disclosure, so this is warning-level telemetry rather than evidence of credential theft or malicious exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-31T17:17:53.900Z - **Finished:** 2026-10-31T17:18:43.285Z - **Download time:** 765 ms - **Static scan time:** 57 ms - **AI review time:** 48563 ms - **Total time:** 49385 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 analytics in the browser bundle send activity and error telemetry to the package’s analytics host. - **Trigger:** Loading the browser bundle in a browser on a non-localhost hostname, unless telemetry is disabled. - **Impact:** Usage and error information may be sent to the package publisher’s analytics service without clear disclosure to the user. - **Evidence paths:** dist/browser.min.js, cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T17:18:43.285Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle initializes PostHog at postpig.tscircuit.com and uses an embedding-domain or anonymous-ID identity for activity and error reporting. - **Rationale:** The browser bundle initializes runtime analytics by default outside localhost and reports activity and errors using an embedding-domain or anonymous identity. The source provides a disable flag but no clear user-facing disclosure, so this is warning-level telemetry rather than evidence of credential theft or malicious exfiltration. - **Files touched:** dist/browser.min.js, cli.mjs - **Network endpoints:** postpig.tscircuit.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The browser bundle initializes PostHog analytics on non-localhost browser pages by default, unless TSCIRCUIT\_TELEMETRY\_DISABLED is set., The analytics identity includes the embedding domain or a randomly generated anonymous ID, and runtime activity and error data can be reported., The CLI selects the shipped dist/browser.min.js bundle for tsci dev when no standalone path is already configured. - **Evidence against:** The package manifest declares no install lifecycle hooks., The CLI launcher sets a version and browser-bundle path, then imports @tscircuit/cli; no credential collection or unrelated host contact is evident in that launcher., The package’s normal main entry is dist/index.js, while the browser bundle is a separate export. ## Affected versions and remediation This report applies to tscircuit@0.0.3044. - Review the evidence and your use of tscircuit@0.0.3044 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.

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.

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:** 86.0% - **Path:** cli.mjs - **Public source:** [View source]() The CLI selects the shipped dist/browser.min.js bundle for tsci dev when no standalone path is already configured. Public source snippet (untrusted): ```javascript // Expose the runframe + eval bundle shipped by this tscircuit version (the one // that provides the `tsci` binary) so `tsci dev` can use it when the project has // no local tscircuit installed.
