But when I run recipe for image recipe on new build, then it also
fetch and compile.
Is the execution of fetch and compile done in some logic inside the
image recipe, i.e. is it correct to assume that there is this logic in
image recipe:

default task = build task only

build task:
    (some logic) -> if required starts fetch and compile task

Is this logic inside the build task ?

Thanks,
