Use-Case-Zuordnung jetzt DETERMINISTISCH aus der Quell-Regulierung (statt LLM/scope-category): control_parent_links.source_regulation (79% der 13.588 MCs) -> Keyword-Mapper -> ~30 Domaenen-Use-Cases. 117/117 Regulierungen gemappt (dse 44 Leitlinien, code_security 10, network_security 9, ...). - use_case_registry.py: 37 Use Cases (Doku + Security + Produkt/Sektor: cra/ai_act/mica/mdr/maschinen/batterie/ehds/dsa/dma/psd2/aml/lksg/...) + use_case_for_regulation() Keyword-Mapper (117 Regulierungen abgedeckt). - migration 150: is_primary auf mc_use_case_mappings + neue mc_regulations (MC->source_regulation, n:m, is_primary) als feine Filter-Dimension. - classify_mc_use_cases.py: source_regulation-getriebener Seed; Primaerzweck = dominante Regulierung, Mehrfachzwecke = weitere. PYTHONPATH-Bootstrap. - 18 Registry-Tests gruen (Mapper-Abdeckung + Konsistenz-Invariante). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
