Who built CDAT Pattern?

CDAT was forged across 2 years of production work on 9 systems - from B2B platforms to e-commerce, CRM, and logistics. Each new project revealed friction in classic POM. Each iteration sharpened the 4 layers and 3 zero-rules into the pattern published here.

This isn't a thought experiment. It's a battle-tested architecture that scales from 5-test prototypes to 500-test enterprise suites.
