symbi-runtime 1.0.0

//! Context management module for agent memory and knowledge systems
//!
//! This module provides the core infrastructure for managing agent contexts,
//! including hierarchical memory systems, knowledge bases, and persistent
//! context storage with session continuity.
//!
//! # Architecture
//!
//! The context system is built around several key components:
//!
//! - **AgentContext**: The main container for an agent's memory and knowledge
//! - **HierarchicalMemory**: Multi-layered memory system (short-term, long-term, working, episodic, semantic)
//! - **KnowledgeBase**: Structured storage for facts, procedures, and learned patterns
//! - **ContextManager**: Trait and implementation for context operations
//!
//! # Usage
//!
//! ```rust,no_run
//! use symbi_runtime::context::{StandardContextManager, ContextManagerConfig};
//! use symbi_runtime::types::AgentId;
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let config = ContextManagerConfig::default();
//! let context_manager = StandardContextManager::new(config);
//! context_manager.initialize().await?;
//!
//! let agent_id = AgentId::new();
//! let session_id = context_manager.create_session(agent_id).await?;
//! # Ok(())
//! # }
//! ```
//!
//! # Features
//!
//! - **Hierarchical Memory**: Multiple memory types with different retention policies
//! - **Knowledge Management**: Structured storage and retrieval of facts, procedures, and patterns
//! - **Semantic Search**: Vector-based similarity search across memory and knowledge
//! - **Session Management**: Persistent context across agent sessions
//! - **Knowledge Sharing**: Secure sharing of knowledge between agents
//! - **Retention Policies**: Automatic archiving and cleanup of old context data
//! - **Access Control**: Policy-driven access control for context operations
