Understanding Layer
The understanding layer is Nucleus's name for the context layer it builds: the layer between organizational data and foundation models where scattered sources become one coherent, verifiable account of what an organization knows. Storage holds the data and the model does the reasoning; the understanding layer makes the two compatible, adding memory, relationships across sources, grounding, and verification. It is an implementation of the context layer category, not a competing concept.
