-### 5. krow-mobile-data-connect
-
-**Purpose:** Centralized backend query management via connectors pattern
-
-**Covers:**
-- Data Connect connectors pattern rationale
-- Connector structure (mirroring backend)
-- Clean Architecture in connectors (domain/data layers)
-- Feature integration pattern
-- Adding queries to existing connectors
-- Creating new connectors
-- Benefits and anti-patterns
-- Current implementation (staff, shifts connectors)
-
-**Use When:**
-- Integrating backend queries into mobile features
-- Creating new connector repositories
-- Adding queries to existing connectors
-- Preventing duplicate backend queries
-- Implementing feature repositories that use connectors
-- Understanding data layer architecture
-
-**Key Documentation:**
