- KI-Copilot: NL query → proposed actions, execute with RBAC, history, audit logging - LLM client: mock mode (no API key) + OpenAI-compatible mode (AI_MODEL/AI_API_KEY) - Action mapper: NL intent → API calls (create/update/delete/search company/contact) - Workflow engine: step types (action/approval/notification/condition), JSONB steps - Workflow lifecycle: pending → in_progress → completed/rejected/cancelled - Event-triggered workflows: event bus → auto-start instances - Code-engine workflows: onboarding on user.created event - Approval timeout: auto-reject after configured hours - 5 new tenant-scoped tables with RLS: ai_conversations, ai_messages, workflows, workflow_instances, workflow_step_history - Migration 0004: all tables + RLS policies + tenant_id + indexes - 238 tests pass (30 AC + 105 coverage + 103 existing), 84.12% T09 module coverage - MissingGreenlet fix: safe accessor helpers for async ORM attribute access
