This warrants a warning for dangerous capability, without source evidence sufficient to establish malicious behavior. - **Files touched:** install.js, package.json, manifest.json, lib/desktop.js - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs install.js automatically during postinstall., install.js downloads the app archive from a configurable base and extracts it during installation., On macOS, install.js removes the quarantine attribute from the downloaded app., lib/desktop.js describes the download as bypassing SmartScreen and Gatekeeper. - **Evidence against:** The download URL is built from the package manifest, and the archive is rejected if its SHA-256 differs from the manifest value., The installer registers the Francois app and its desktop entry, consistent with the package’s stated product. ## Affected versions and remediation This report applies to francois@0.60.0. - Review the evidence and your use of francois@0.60.0 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.
