1//! # Leviath Core
2//!
3//! Core types and traits for the Leviath agent framework.
4//!
5//! This crate provides the foundational types for building agents with structured,
6//! hardware-inspired context window management. It includes:
7//!
8//! - **Regions**: Typed memory regions with different lifecycle policies
9//! - **Layouts**: Complete memory maps defining how context is structured
10//! - **Blueprints**: Agent definitions including stages, models, and tools
11//! - **Lifecycle**: Policies for eviction, compaction, and context management
