fortress of cryptographic strength, implementing STARK (Scalable Transparent Argument of Knowledge) proofs with the unyielding security of Winterfell's walls, memory safety as solid as the castle's foundation, and zero-cost abstractions that would make even the most cunning Lannister envious.                                               \n\n## ⚔️ The XFG Winterfell Arsenal\n\n### 🛡️ Core Defenses\n\n- **⚔️ Field Arithmetic**: Type-safe field element operations with constant-time implementations that would make the Night's Watch proud\n- **📜 Polynomial Operations**: Efficient polynomial arithmetic and evaluation, more precise than even Mæster Luwin's calculations\n- **🏰 STARK Proof System**: Complete STARK proof generation and verification- the cryptographic equivalent of Winterfell's defenses\n- **𐂷 Type System**: Comprehensive type definitions for all cryptographic operations, as thorough as the Stark family tree\n\n### 🛡️ Security Fortifications\n\n- Constant-time cryptographic operations that never reveal their secrets\n- Secure secret management with zeroization.\n- Type-level prevention of timing attacks, more reliable than the Wall's magic\n- Memory safety through Rust's type system as strong as Valyrian steel\n- Comprehensive error handling with Result types as true as the word of Ned Stark's son.\n\n### ⚡ Performance ~~Weapons~~ Tools\n\n- Zero-cost abstractions for all operations as efficient as Arya's water dancing\n- Optimized field arithmetic implementations as fast as direwolves\n- Efficient polynomial evaluation algorithms as precise as one of The L3-eyed Raven's visions\n- Minimal runtime overhead for type safety as light as a crow's feather\n\n## ⛫ Building Winterfell\n\n### Prerequisites\n#### The forge of the North\n\n- Rust 1.70+

Operations\n\n```rust\nuse xfg_stark::types::field::PrimeField64;\n\n// Create field elements - Forging the weapons\nlet a = PrimeField64::new(5);\nlet b = PrimeField64::new(3);\n\n// Perform arithmetic operations - The art of war\nlet sum = a + b;\nlet product = a * b;\nlet inverse = a.inverse().unwrap();\n\n// Constant-time operations - The way of the North\nlet ct_sum = a.add_constant_time(\u0026b);\nlet ct_product = a.mul_constant_time(\u0026b);\n```\n\n### Polynomial Operations\n\n```rust\nuse xfg_stark::types::polynomial::FieldPolynomial;\nuse xfg_stark::types::field::PrimeField64;\n\n// Create polynomials - Crafting the spells\nlet coeffs = vec![PrimeField64::new(1), PrimeField64::new(2), PrimeField64::new(1)];\nlet poly = FieldPolynomial::new(coeffs);\n\n// Evaluate polynomial - Casting the magic\nlet result = poly.evaluate(PrimeField64::new(3));\n\n// Polynomial arithmetic - The maester's calculations\nlet poly2 = FieldPolynomial::constant(PrimeField64::new(1));\nlet sum = poly.add(\u0026poly2);\nlet product = poly.multiply(\u0026poly2);\n```\n\n### STARK Proof Components\n\n```rust\nuse xfg_stark::types::stark::{StarkProof, ExecutionTrace, Air};\nuse xfg_stark::types::field::PrimeField64;\n\n// Create execution trace - The witness of the North\nlet trace = ExecutionTrace {\n    columns: vec![vec![PrimeField64::new(1), PrimeField64::new(2)]],\n    length: 2,\n    num_registers: 1,\n};\n\n// Create AIR constraints - The laws of the realm\nlet air = Air {\n    constraints: vec![],\n    transition: TransitionFunction {\n        coefficients: vec![vec![PrimeField64::new(1)]],\n        degree: 1,\n    },\n    boundary: BoundaryConditions { constraints: vec![] },\n
