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 launcher sends a potentially identifying home-directory path in runtime error telemetry to a configured PostHog endpoint. The environment-variable gate limits when this occurs, but the path is still identifying data, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-11-02T05:22:58.350Z - **Finished:** 2026-11-02T05:23:47.813Z - **Download time:** 503 ms - **Static scan time:** 162 ms - **AI review time:** 48797 ms - **Total time:** 49463 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:** Configured runtime error telemetry sends a local home-directory path as an analytics identifier. - **Trigger:** A download failure occurs while a PostHog API key and host environment variable are set. - **Impact:** The home-directory path can identify the local user or account to the analytics service. - **Evidence paths:** launcher.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T05:23:47.813Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher posts the failure event and \`anonymous-${CONFIG.homeDir}\` to the configured host’s \`/capture/\` endpoint. - **Rationale:** The launcher sends a potentially identifying home-directory path in runtime error telemetry to a configured PostHog endpoint. The environment-variable gate limits when this occurs, but the path is still identifying data, so this warrants a warning rather than a block. - **Network endpoints:** configured PostHog host from SAVANT\_CODE\_POSTHOG\_HOST or NEXT\_PUBLIC\_POSTHOG\_HOST\_URL, registry.npmjs.org, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Launcher telemetry activates when a PostHog API key and host are supplied through environment variables., The event includes \`CONFIG.homeDir\` as its distinct ID, along with update error details and platform information., The launcher posts the event to the configured host’s \`/capture/\` endpoint after a download failure. - **Evidence against:** The manifest declares \`prepack\` and \`postpack\` scripts, with no install lifecycle hook., The entry point calls \`launcher.main()\` only when run as the CLI., The launcher downloads Savant Code releases and asks for approval before installing a staged update interactively. ## Affected versions and remediation This report applies to savant-code@0.0.31. - Review the evidence and your use of savant-code@0.0.31 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.
