NeuroRoute C is our biggest standalone open-source project. A small C11 engine that helps a system choose where to go next: it weighs the available paths, selects the strongest, records that it was used, and falls back safely when no valid route exists. It also includes a 256-bit Hamming-distance matcher that compares compact binary fingerprints to find the most similar stored entry. It is not an LLM or neural network — an experimental systems component focused on deterministic selection, reproducibility and inspectable behavior, with no APIs, external dependencies or network calls.
