//! # AllSource Core - High-Performance Event Store
//!
//! A high-performance event sourcing platform built in Rust, following Clean Architecture principles.
//!
//! ## Architecture Overview
//!
//! The codebase follows a layered Clean Architecture:
//!
//! ```text
//! ┌─────────────────────────────────────────────────────────────┐
//! │                    Infrastructure Layer                     │
//! │  (HTTP handlers, WebSocket, persistence, security)          │
//! │  infrastructure::web, infrastructure::persistence,          │
//! │  infrastructure::security, infrastructure::repositories     │
//! ├─────────────────────────────────────────────────────────────┤
//! │                    Application Layer                        │
//! │  (Use cases, services, DTOs)                                │

//! │  (Entities, value objects, repository traits)               │
//! │  domain::entities, domain::value_objects,                   │
//! │  domain::repositories                                       │
//! └─────────────────────────────────────────────────────────────┘
//! ```
//!
//! ## Module Organization
//!
//! - **domain**: Core business entities, value objects, and repository traits
//! - **application**: Use cases, services, and DTOs that orchestrate domain logic
//! - **infrastructure**: Concrete implementations (web, persistence, security)
//!
//! ## Quick Start
//!
//! ```rust,ignore
//! use allsource_core::{EventStore, Event, IngestEventRequest};
//!
//! let store = EventStore::new();
//! let event = Event::from_strings(
//!     "user.created".to_string(),
//!     "user-123".to_string(),
//!     "default".to_string(),
//!     serde_json::json!({"name": "Alice"}),
//!     None,
//! )?;
//! store.ingest(event)?;
//! ```
