Implements a reusable, self-contained fixed-size block allocator using a free list. It provides O(1) allocation and deallocation for objects of a predefined size, with no internal dependencies beyond standard C++ headers. This pattern is easily extractable for any project needing fast, low-fragmentation allocation of same-sized objects.

A reference-counted copy-on-write container for an array of context models (CABAC probability states). The design allows efficient cloning of the entire table for rate estimation and multi-option encoding, with shared ownership and lazy copying. The pattern is self-contained and applicable to any data structure requiring COW semantics.

A C++ template framework for evaluating multiple coding options and selecting the one with the lowest rate-distortion cost. It provides a clean, reusable pattern for implementing decision trees in any optimization context, with support for cost accumulation, backup/restore, and parallel evaluation. The template is header-only and depends only on standard types.

A generic typed parameter system with built-in command-line argument parsing. It supports integer, float, boolean, and string parameters with range constraints, help generation, and automatic validation. This module is self-contained and can be reused in any application that needs a configurable parameter interface with minimal overhead.
