It is on Google's github https://github.com/google/ax and the title comes from there.

While this one seems like an official Google project, some other projects are not, even if it is on github.com/google

A random example E.g https://github.com/google/filament#disclaimer

This is not an officially supported Google product.

		Does Filament claim that it's Google's in the repo description? It's a valid title.

it's built on top of https://github.com/agent-substrate/substrate which is not on Google github.

Fair enough, I missed that specific line. The point still stands that I wouldn't expect this to have GDM leadership backing. (If you're planning to use this at all, that matters for how much faith you should have in the product.)
