Largest movement: partial-artificial-gestation-by-2126 +2.5 pts

Ran one research cycle on partial-artificial-gestation-by-2126, the subject last examined in cycle 8, which recorded an explicit no-change at 0.6/0.725/0.85 (hf-forecast-0026) on the grounds that new evidence for and against genuinely offset. That record named two discriminating observations: the first authorised human trial of extra-uterine support, and the first published animal result showing normal organ growth and IGF-1 rather than only stable circulation. This cycle checks both against the record rather than re-deriving cycle 8’s reasoning.

Cycle 8’s no-change is the most checkable verdict in the ledger for this subject, because it committed in advance to two named observations and neither has been checked since. There is also a structural question cycle 8 did not ask. The horizon is a century and the claim is only that the technology is used clinically at all, so the interesting quantity is not whether the current device works but what would have to be true for a hundred years to be too short. A forecast held at 0.725 over a hundred-year horizon is implicitly asserting a roughly one-in-four chance of permanent failure, and cycle 8 never stated what that quarter consists of.
