//! # Lineage Finance - Evolutionary AI Trading Platform
//!
//! This module extends Lineage with financial domain concepts:
//! - Irreversible trades with no rollback capability
//! - Finite capital (energy) as resource constraint
//! - Permanent damage from losses (scars)
//! - Evolutionary spawning of successful agents
//! - Trust scoring based on performance history
//! - Multi-agent competitive simulations
//!
//! ## Core Philosophy
//!
//! Financial agents in this system face real consequences:
//! - Losses leave permanent scars that increase future costs
//! - Poor performance leads to death (zero capital)
//! - Successful agents spawn inheriting optimized traits
//! - History is append-only and auditable forever
