gatewarden 0.3.0

//! Fused Semantic Execution (FSE) Policy Engine.
//!
//! This software implements Fused Semantic Execution (FSE), a selector-first,
//! single-pass rule evaluation architecture. FSE is the subject of a pending
//! patent by Michael A. Kuykendall. All rights reserved.
//!
//! # Architecture
//!
//! FSE inverts the conventional rule-first evaluation model. Instead of iterating
//! rules and extracting values for each, FSE:
//!
//! 1. **Compiles** rules into a `CompiledPlan` with deduplicated selectors
//! 2. **Executes** by iterating unique selectors once, broadcasting each value
//!    to all rules that reference it
//! 3. **Finalizes** by forcing unresolved required rules to False (fail-closed)
//!
//! The core invariant: `∂runtime / ∂rules ≈ 0` for shared selectors.
