Goodecode update/install behavior must not bypass macOS Gatekeeper. The extension must not delete com.apple.quarantine, run spctl --master-disable, or execute unverified downloads.
Public Goodebot downloads are distributed through https://goodebot.net/download, outside the extension. Published desktop releases should use HTTPS, release manifests, SHA-256 verification, app bundle validation, code-signature verification, and Gatekeeper assessment.
