AI-powered article generation pipeline built in n8n. The workflow uses a modular sub-workflow architecture, the top-level flow handles input validation, routing logic, and batch orchestration, while sub-workflows manage individual tasks like research, content generation, and publishing. Built with shared run IDs for logging consistency across all branches, True/False routing for error handling, and per-item processing using n8n's each mode. Currently running in production publishing content automatically to WordPress and multiple Shopify stores simultaneously.
