//! Compiler knowledge-base rules.
//!
//! This module contains the data model and runtime helpers used by the active
//! compiler rule system. A knowledge rule describes an ordered match pattern,
//! optional symbolic-parameter conditions, and a rewrite target.
//!
//! The main layers are:
//! - [`rule`]: runtime rule structures and structural validation.
//! - [`rule_dsl`]: parser, loader, lowering, and dumper for `.rule` files.
//! - [`library`]: validated rule storage, stable rule ids, metadata, and gate
//!   indexes for candidate selection.
//! - [`matcher`]: adjacent-operation structural matching, binding, condition
//!   checks, and target instantiation.
//! - [`rule_equivalence`]: symbolic and sampling-based equivalence validation.
//!
//! Transform passes should use [`RuleLibrary`] to select candidate rules, then
//! use matcher helpers to bind a specific operation window. Search policy,
//! commutation-aware scans, cost decisions, and circuit patching live outside
//! this module.
