We should probably remove the dependency on stage, this is very much circular: stage needs outs/deps, and outs/deps require stages, so, when we construct a stage, there's no way beforehand to create outs/deps without creating a stage first without any deps/outs.

@skshetry you mean from the outputs/deps themselves? We still use it in some places, so easier said than done. Logically outs and deps do belong to the stage, but the way we create and fill them is not very friendly, I agree.

What I am trying to say is, Output should not get access to the Stage at all. We could pass wdir and repo if they need it.

❌ I will check DeepSource, CodeClimate, and other sanity checks below. (We consider them recommendatory and don't expect everything to be addressed. Please fix things that actually improve code or fix bugs.)
