Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 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:** 0.2.0-rc.3 - **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 package discloses host-controlled telemetry, but its records can contain document identifiers and local source paths. That identifying data makes this a warning-level telemetry concern rather than a clean result. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T10:36:47.155Z - **Finished:** 2026-11-01T10:37:39.919Z - **Download time:** 1034 ms - **Static scan time:** 1447 ms - **AI review time:** 50282 ms - **Total time:** 52764 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 may include document and source paths in operation records. - **Trigger:** Workbench startup begins the logger; records are sent if the host reports telemetry enabled. - **Impact:** The host operator may associate user activity with local document identifiers and source paths. - **Evidence paths:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Review source:** ai\_review - **Reviewed:** 2026-11-01T10:37:39.919Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The logger batches operation attributes and sends them to the same-origin \`api/presmium/telemetry\` endpoint. - **Rationale:** The package discloses host-controlled telemetry, but its records can contain document identifiers and local source paths. That identifying data makes this a warning-level telemetry concern rather than a clean result. - **Files touched:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Network endpoints:** api/presmium/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Workbench construction starts an operation logger, which asks the host whether collection is enabled., Logged events can include the current document identifier and source paths, including file paths from changes and a path revealed by the user., When enabled, batches are sent to the same-origin \`api/presmium/telemetry\` endpoint using \`sendBeacon\` or \`fetch\`., The source describes this as telemetry for the operator’s collector and says the host controls whether it collects. - **Evidence against:** The manifest defines no lifecycle scripts; the package exports UI components and related workbench code., Telemetry is gated on the host returning \`enabled: true\`; the flagged transcription flow sends its plan only after a user requests review and applies changes only after confirmation. ## Affected versions and remediation This report applies to @lincyaw/workbench@0.2.0-rc.3. - Review the evidence and your use of @lincyaw/workbench@0.2.0-rc.3 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.
