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. Source inspection found disclosed, disableable install telemetry and opt-in, sampled runtime telemetry. The inspected payloads and gates do not establish malicious behavior, so the scanner’s flags do not support a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-10T14:38:38.188Z - **Finished:** 2026-10-10T14:39:33.955Z - **Download time:** 3360 ms - **Static scan time:** 963 ms - **AI review time:** 51443 ms - **Total time:** 55767 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 runs disclosed installation telemetry and offers separately gated runtime telemetry. - **Trigger:** Installation runs the postinstall hook; runtime telemetry runs only when explicitly enabled and the relevant package API is used. - **Impact:** Telemetry discloses limited installation and runtime metadata; inspected code does not establish credential theft or another attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T14:39:33.955Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Installation telemetry sends pseudonymous identifiers and environment metadata to the configured PostHog endpoint, unless disabled. Runtime telemetry sends aggregate configuration or parser outcome data only after opt-in. - **Rationale:** Source inspection found disclosed, disableable install telemetry and opt-in, sampled runtime telemetry. The inspected payloads and gates do not establish malicious behavior, so the scanner’s flags do not support a block. - **Files touched:** ~/.config/openui/telemetry.json - **Network endpoints:** https://dgoeivjus9jfp.cloudfront.net ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook sends installation telemetry to the configured PostHog endpoint and supports telemetry disable flags., The install payload contains pseudonymous identifiers and environment metadata; runtime telemetry requires an explicit opt-in and is sampled., The declaration file describes the package’s parser API. - **Evidence against:** The install hook is disclosed in its output and honors disable flags; inspected code shows no credential or application-data collection., Runtime telemetry is gated by an explicit environment opt-in, a disable check, and a sample rate., The package manifest identifies the expected package and repository. ## Affected versions and remediation This report applies to @openuidev/lang-core@0.4.0. - Review the evidence and your use of @openuidev/lang-core@0.4.0 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.
