Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged source implements user-directed transcription editing, and the inspected network client targets the workbench API. Telemetry is disclosed in source and sends only after the host enables collection; no malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T10:46:00.753Z - **Finished:** 2026-11-01T10:46:39.661Z - **Download time:** 1297 ms - **Static scan time:** 1441 ms - **AI review time:** 36169 ms - **Total time:** 38908 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:** No attack was identified. The package provides a React workbench with a same-origin workspace client and host-controlled operation telemetry. - **Trigger:** Consumers import the exported components; user actions invoke workbench operations. Telemetry starts through the workbench and remains disabled unless the host reports it enabled. - **Impact:** No malicious impact identified; ordinary workbench requests and host-enabled telemetry are the observed network behavior. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T10:46:39.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Workspace requests use the configured API base, which defaults to relative api/presmium/. Enabled telemetry batches UI operations to that host. Transcription edits are saved to browser localStorage and previewed only on user action. - **Rationale:** The flagged source implements user-directed transcription editing, and the inspected network client targets the workbench API. Telemetry is disclosed in source and sends only after the host enables collection; no malicious behavior was found. - **Files touched:** browser localStorage: presmium.transcription-draft.v1:\*, browser localStorage: presmium.telemetry.browser - **Network endpoints:** api/presmium/, api/presmium/telemetry ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports its React workbench source entry points; package.json declares no lifecycle scripts or executable bin., Transcription drafts are stored in browser localStorage under a workbench-specific key., Transcription preview requires an explicit user action and checks that the authoring source is ready., Telemetry sends operations to the same-origin workbench host only after that host reports collection is enabled. - **Evidence against:** The inspected network client uses the configurable workbench API base, defaulting to the relative path api/presmium/., No credential collection, unrelated network destination, install-time action, or unsolicited account action was identified. ## Affected versions and remediation This report applies to @lincyaw/workbench@0.2.0-rc.2. - Review the evidence and your use of @lincyaw/workbench@0.2.0-rc.2 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.
