Struct EngineContext 

pub struct EngineContext<'a> {
    pub world: Option<&'a mut dyn Any>,
    pub services: ServiceRegistry,
}

Engine context providing access to various subsystems.

This structure is shared across both the Strategic Brain (Agents) and the user-facing application logic.

Design

Subsystem-specific services (e.g., GraphicsDevice, RenderSystem) are accessed through the generic ServiceRegistry instead of named fields. This respects the Interface Segregation Principle: each agent fetches only the services it needs, and adding new services never changes this struct.

Fields

world: Option<&'a mut dyn Any>

A type-erased pointer to the main ECS World. This allows agents to access data without khora-core depending on khora-data.

services: ServiceRegistry

Generic service registry — agents fetch typed services as needed.
