Architecture

Architectural Layers

User Specification Layer

The interface through which users declaratively specify validation workflows and experiment configurations.

Execution Orchestration Layer

The internal coordination system that transforms user specifications into executable validation workflows.

Backend Integration Layer

The abstraction layer that unifies experiment tracking and management across multiple backend systems.

External Dependency Layer

The interface that connects the framework to external systems for validation computation and experiment persistence.
