Standalone, zero-dependency C++ elliptic curve library implementing the Ran/Shaw curve for FCMP++. Runtime-dispatched backends (portable, x64, AVX2, AVX-512 IFMA) with constant-time scalar multiplication, MSM, polynomial arithmetic, and ECFFT support.

A simple FCMP-based check-in/check-out storage system using dictionary objects in SAS-store and retrieve data by key, like a digital cloakroom. Additionally, macro-based stack and queue functions are provided.

Elliptic curve 2-cycle realize pipeline: constructs CM-method curve pairs over p = 2^255-19 for recursive proof composition (IVC/SNARK/FCMP++). Finds polynomial roots over finite fields, converts class invariants to j-invariants, and emits short Weierstrass parameters with twist security analysis
