The application cannot be opened because it is from an unidentified developer

Question:

Please note before reading the following: "Tell them to go to System preferences > Security & privacyand allow 3rd party applications to run. It is not acceptable to solve this problem.

I created .appone that was signed with a valid Mac developer certificate. However, downloading it from the Internet and starting it still gives a security request:

The application cannot be opened because it is associated with an unidentified developer

This is a terminal dump codesign -vvvfor .app:

I do not understand why this does not go through Gatekeeper? Is something missing? Does Apple require additional payments / bribes or something else?
