I think your posts ultimately led me to realize where I went wrong. There's a procedural difference between local signing that Xcode does when building and actual notarization process with Apple. My application was signed, but that copy was not notarized, that's why Gatekeeper won't let me run it when it's quarantined, but let me run outside of quarantine.
