+## hdc99 — Standalone HDC Library in C
+* **Project specification:** A minimal, dependency-free C99 library providing all core hyperdimensional computing operations: bind, bundle, permute, normalize, and cosine similarity. Supports user-defined vector dimensions up to 10,048.
+* **Implementation:** C99
+* **Remarks:** Single-header, two-file library (hdc.h + hdc.c) that can be dropped into any project. No external dependencies beyond the standard library. Includes helper utilities for vector zeroing and copying.
