Remove standalone services (ai-compliance-sdk root, developer-portal, dsms-gateway, dsms-node, night-scheduler) and legacy compliance/dsgvo pages. Add new SDK pipeline modules (academy, document-crawler, dsb-portal, incidents, whistleblower, reporting, sso, multi-tenant, industry-templates). Add drafting engine, legal corpus files (AT/CH/DE), pitch-deck, blog and Förderantrag pages. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
