Module sync 

Sync Command - The ONLY command in ggen v5

ggen sync is the unified code synchronization pipeline that replaces ALL previous ggen commands. It transforms domain ontologies through inference rules into typed code via Tera templates.

Architecture: Three-Layer Pattern

• Layer 3 (CLI): Input validation, output formatting, thin routing
• Layer 2 (Integration): Async execution, error handling
• Layer 1 (Domain): Pure generation logic from ggen_core::codegen

Exit Codes
