1//! Override data models and types
2//!
3//! This module defines the core data structures for the override system:
4//! - OverrideRule: Configuration for applying overrides
5//! - OverrideMode: How patches are applied
6//! - PatchOp: Individual patch operations
7//! - Overrides: Container for multiple rules
