Anfragen.tsx: 481→320 lines
- anfragenKiDetection.ts: STAGE_ORDER, STAGE_LABELS, KI_RULES, detectKiStage
- AnfragenMessageBubble: chat message bubble component
- AnfragenInquiryItem: inquiry list row component

AISearch.tsx: 398→342 lines
- needSearchMapper.ts: generateSummary + buildNeedInput pure functions
