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. This is not clearly malicious, but host-enabled runtime telemetry can transmit document and local file identifiers without an apparent user-facing consent or opt-out. The endpoint is relative to the host and no credential or content exfiltration was identified, so this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-01T05:16:13.248Z - **Finished:** 2026-11-01T05:17:25.023Z - **Download time:** 1016 ms - **Static scan time:** 1372 ms - **AI review time:** 69386 ms - **Total time:** 71775 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:** Host-enabled runtime telemetry can expose project-identifying document and file paths alongside interaction labels. - **Trigger:** Workbench construction starts telemetry; data is recorded and sent when the host reports telemetry enabled. - **Impact:** The host operator can associate user interactions with document and local file names. No credentials or document contents were found in this flow. - **Evidence paths:** src/telemetry.ts, src/workbench.ts, src/workspace-client.ts - **Review source:** ai\_review - **Reviewed:** 2026-11-01T05:17:25.023Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The workbench collects click and operation metadata, including document identifiers and file paths, then sends JSON batches to its relative telemetry endpoint. - **Rationale:** This is not clearly malicious, but host-enabled runtime telemetry can transmit document and local file identifiers without an apparent user-facing consent or opt-out. The endpoint is relative to the host and no credential or content exfiltration was identified, so this warrants a warning rather than a publish block. - **Network endpoints:** same-origin api/presmium/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Workbench creation starts operation telemetry automatically; it asks the host whether collection is enabled., When enabled, click records include control labels, roles, activity tags and region labels., Operation records can include the current document identifier and changed or revealed file paths., Batches go to the relative api/presmium/telemetry endpoint; no unrelated collector or credential transfer was identified. - **Evidence against:** Telemetry is disabled unless the host reports enabled=true., The flagged transcription component stores drafts locally and applies changes only after a review and explicit apply action. ## Affected versions and remediation This report applies to @lincyaw/workbench@0.2.0-rc.10. - Review the evidence and your use of @lincyaw/workbench@0.2.0-rc.10 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.
