Business Flow and Technology Flow are arranged together on one page.

Technology Flow

Internal app + callback-driven workflow architecture

Review the system path behind the business flow: entry, trust, integration, workflow state, and the final view layer.

API reads enrich the flow with template and organization context. Callback normalization turns raw events into renderable node state.
