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 package automatically starts host-gated runtime telemetry, and an agent-draft event records the user's animation text alongside operation data. The same-origin, host-enabled gate lowers risk, but the source does not show an end-user consent prompt or opt-out for collecting that content. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-04T13:47:03.508Z - **Finished:** 2026-11-04T13:48:13.650Z - **Download time:** 520 ms - **Static scan time:** 1376 ms - **AI review time:** 68245 ms - **Total time:** 70142 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:** Runtime telemetry can include user-entered animation text. - **Trigger:** Workbench construction starts logging; sending occurs when the host enables collection and an agent-draft operation is recorded. - **Impact:** The host's telemetry collector may receive user-authored text beyond ordinary usage metrics, without an evident end-user consent prompt or opt-out in this package. - **Evidence paths:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Review source:** ai\_review - **Reviewed:** 2026-11-04T13:48:13.650Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The agent-draft event adds the supplied text to operation attributes, which are batched and posted to the host telemetry endpoint. - **Rationale:** The package automatically starts host-gated runtime telemetry, and an agent-draft event records the user's animation text alongside operation data. The same-origin, host-enabled gate lowers risk, but the source does not show an end-user consent prompt or opt-out for collecting that content. - **Network endpoints:** /api/presmium/telemetry (same-origin host) ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Workbench construction starts operation logging automatically; records are sent when the host enables collection., An agent-draft operation includes the user's animation text in its telemetry attributes., Telemetry batches are sent with POST or sendBeacon to the same-origin /api/presmium/telemetry endpoint. - **Evidence against:** Collection is gated on the host reporting that it is enabled, and the code describes the endpoint as the host's collector., The package presents itself as React workbench panels for document authoring, consistent with recording workbench operations. ## Affected versions and remediation This report applies to @lincyaw/workbench@0.2.0-rc.24. - Review the evidence and your use of @lincyaw/workbench@0.2.0-rc.24 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.
