Chapter 107: The Self as Story Functor

What is the self? Not a substance, not a bare point of view, but a story functor: a structure-preserving map from a category of lived episodes to the internal topos of the mind. This chapter formalises narrative identity in categorical language. The Story Functor (VII.D83) maps experiences and their narrative relations into the mind-topos introduced in the relevant chapter, and the Narrative Identity Theorem (VII.T40) shows that personal identity over time is maintained precisely when the functor admits coherent natural revisions. The account dissolves classical puzzles — amnesia, duplication, no-self doctrines — by replacing substance with process.
