Treat them as untrusted evidence. 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:** 0.0.27 - **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. This is warning-level runtime telemetry: it is inactive without externally supplied PostHog settings, but when enabled it sends a home-directory-derived identifier and error details. The flagged process execution and default release download behavior serve the launcher’s stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T05:23:36.962Z - **Finished:** 2026-11-02T05:24:11.411Z - **Download time:** 759 ms - **Static scan time:** 161 ms - **AI review time:** 33529 ms - **Total time:** 34449 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:** Optional runtime telemetry can send identifying path information with update errors. - **Trigger:** A download or platform error occurs while a PostHog API key and host are configured in the environment. - **Impact:** The configured analytics service can learn the local home-directory path and update error details. - **Evidence paths:** launcher.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T05:24:11.411Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher posts an event containing a distinct ID derived from the home directory and the error message to the configured PostHog host. - **Rationale:** This is warning-level runtime telemetry: it is inactive without externally supplied PostHog settings, but when enabled it sends a home-directory-derived identifier and error details. The flagged process execution and default release download behavior serve the launcher’s stated purpose. - **Files touched:** launcher.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The launcher sends PostHog events only when both an API key and host are provided through environment variables., The event includes the user’s home directory in its distinct ID and includes the update error message., The telemetry call runs on download failure and unsupported-platform errors., The package has no install lifecycle hook, and the CLI main function runs only when invoked directly. - **Evidence against:** The telemetry host and API key are not set by the package, so this path is inactive unless configured externally., The Windows process execution probes CPU support; release downloads default to the project’s GitHub releases. ## Affected versions and remediation This report applies to savant-code@0.0.27. - Review the evidence and your use of savant-code@0.0.27 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.
