NMCA (Neurosymbolic Multimodal Cognitive Architecture) Addendum - 2026

This architectural addendum accompanies the 2026 NMCA (Neurosymbolic Multimodal Cognitive Architecture) blueprint and provides a consolidated cognitive map and tools/implementation assessment for all 128 proposed modules. The purpose of this addendum is to clarify what the 128-module architecture is intended to represent as a possible artificial mind, how the proposed functions relate to one another, and which aspects can currently be attempted with available software and engineering tools. The architecture was not designed as a minimum viable AI system or solely as a task-oriented tool. Its underlying design goal is to explore what would be required for an artificial mind capable of persistent identity, memory, visual-symbolic thought, emotional regulation, social cognition. The cognitive map therefore distinguishes between primary cognitive functions, functions that may be implemented as part of other modules, and surrounding infrastructure such as multi-agent environments, development tooling, testing systems, and containment mechanisms. All 128 original module headings are retained; this addendum does not replace, revise, or supersede the original NMCA blueprint. The accompanying tools map provides a separate 2026 assessment of what can currently be attempted with available software. It distinguishes between capabilities for which useful implementation machinery exists, capabilities for which only significant partial components exist, and functions for which no established software stack currently provides a convincing implementation. The existence of a tool or library is not treated as evidence that the corresponding cognitive function has been solved. This document is an architectural and conceptual assessment, not a claim that NMCA has been implemented, or that every proposed module is independently necessary. It is intended to make the architecture's functional assumptions, design goal, and present-day implementation landscape explicit for future researchers, engineers, and reviewers. The original NMCA blueprint remains the primary architectural document. This addendum is provided as a companion reference explaining the cognitive interpretation and current technological feasibility of the proposed architecture. Status: Theoretical specification with minimum-viable-loop descriptions. A complete running system is not claimed. Intended for research, sandbox simulation, and human-guided exploration. Not for autonomous deployment.
