• Components anyway need to be available when you define the pipeline controller/decorator, i.e. same codebase

No you an specify a different code base, see here:

Is the code in this "other" repo downloaded to the agent's machine? Or is the component's code pushed to the machine on which the repository is?
If the second case is true: How is the other machine (on which the other repo is lying on) turned into an agent?
