Data layer, frontend, infrastructure, specialized services
Wave 2 — backend logic runs after foundation (DATA, QA, INFRA, DESIGN) is in place.
Merges after DATA, before FRONTEND. Backend APIs must exist before frontend consumes them.
Steady and focused. Each handler/service fix is a discrete unit. Avoid sprawling changes that cross into the data layer or frontend.
