Yes; I mentioned that in the full version. The brain is full of information that we're not conscious of. This is necessarily so when you have regions of the graph of K with low connectivity. A more complete analysis would look for uniquely-grounded subsets of K. For example, it's plausible that infants thrashing their arms around blindly have knowledge in their brains about where there arms are and how to move them, but are not conscious of that knowledge; but are conscious of simpler sensation.
