This repository is a static academic companion to the book 'Computational Cognitive Modeling and Linguistic Theory' (2020). With 50 stars and zero recent activity (velocity 0.0/hr), it functions as a digital archive rather than a living software project. Its defensibility is minimal because it is an educational resource for a niche symbolic AI framework (ACT-R) rather than a proprietary technology. Frontier labs (OpenAI, Anthropic) have essentially zero interest in classical symbolic cognitive architectures like ACT-R, as they focus on transformer-based neural architectures; thus, the frontier risk is low due to domain divergence. The project's value is purely pedagogical, serving researchers in psycholinguistics who wish to bridge the gap between formal linguistic theory and cognitive architectures. While it is 'infrastructure' for a specific sub-field, it lacks the network effects or technical moats required for a higher score. It is unlikely to be displaced simply because it is a historical record of a specific publication's methodology.
