Iteration 25 — Family 14 falls 4 HARVESTED · 95 TOTAL ALL 20 FAMILIES TOUCHED

In plain words: the last untouched shelf of the library got its visit. The forecast-comparison classics are the tools econometricians built to answer "is model A really better than model B, or is that noise?" — and they were built from day one for exactly our substrate problem, with corrections for serially dependent errors baked in. Four entered: the 1995 Diebold–Mariano test (the field's workhorse), the Giacomini–White conditional test — which is the regime-scoping question in its native statistical form ("is this thing better WHEN the market is in state X?"), Hansen's data-snooping-robust superiority test, and the Model Confidence Set, whose set-valued answer ("these regimes are statistically indistinguishable from the best") is precisely the shape a scoping verdict wants. With this, every one of the twenty method families has now been visited at least once — the map has no blank continents left, only three shelves with named leftovers. The four newcomers face the gates next; two passers close the regime-scoping gap and fire the sixth handoff — which would put candidate batches on the lab's shelf for every boundary in the machine.
