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. Static inspection found no lifecycle hook or concrete malicious behavior. Browser automation and page-script execution are explicit product capabilities with a loopback-only DevTools endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-22T18:39:19.833Z - **Finished:** 2026-09-22T18:40:14.332Z - **Download time:** 509 ms - **Static scan time:** 374 ms - **AI review time:** 53616 ms - **Total time:** 54499 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 surface was identified. The package is an explicitly invoked browser-control client and constrains its DevTools connection to loopback. - **Trigger:** A user runs the r5d-browser start command or submits a run\_js browser action. - **Impact:** No unconsented install-time behavior, credential harvesting, or unrelated network exfiltration was identified. - **Review source:** ai\_review - **Reviewed:** 2026-09-22T18:40:14.332Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It launches a dedicated Chrome session and performs supplied browser actions; run\_js evaluates supplied code only in the browser page context. - **Rationale:** Static inspection found no lifecycle hook or concrete malicious behavior. Browser automation and page-script execution are explicit product capabilities with a loopback-only DevTools endpoint. ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Package metadata defines library and CLI entrypoints and contains no lifecycle install hook., The browser client starts only for the explicit start command., Chrome DevTools connections are restricted to the local loopback endpoint., Browser JavaScript execution requires a supplied run\_js action. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790101818895.g2cde24151550775ca3fa10b950e18bbe0118592f. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790101818895.g2cde24151550775ca3fa10b950e18bbe0118592f before allowing it.
