All 48 open questions from the R1 intake are answered in
requirements/r1-klaerungen.md. Acceptance criteria, requirements and
backlog are updated accordingly; removed criteria stay marked as
"entfällt" so references keep their numbers. New stories KTO-11
(settings, #28) and QUE-09 (dashboard, #29). backlog.md lists the data
model changes for the architect and new open questions N1-N14.
