AssessObligationStatus traverses obligation_id -> (citation_unit) -> accepted
controls -> required evidence -> status (erfuellt|offen|unklar). Evidence
presence is a callback; MVP passes nil (nothing collected yet) -> offen.
citation_spans = "pending" until the Legal-Knowledge-Graph session attaches
them. This is the vertical slice that makes the graph a product feature:
"CRA obligation fulfilled because evidence X/Y/Z is present", not "a doc exists".
