I don't see any evidence you did this. Sorry. Everything you're asking
is described in the R1 docs - in detail. Although the R1 docs could be
better they're quite explicit and give examples on the things you're
asking for.
It appears that you've made up your mind how it has to work, and you're
fighting what the docs say, or ignoring what they say because it doesn't
agree with your pre-conceived notion.
This is MUCH simpler than you're making it.
