+--- Outcome, item 24 (closed 2026-07-17 ~02:10, STOPPED by Nils
+mid-eval: "stop that idea. does not seem to work either"). Training
+completed; evidence at stop: val easy 0.346 / hard 0.405 vs
+adapter-only 0.356/0.361 — the trainable band did not improve fit
+(hard slightly worse), consistent with the registered prediction that
+capacity/expressivity is not what binds. k=0 sanity row with trained
+LoRA loaded reproduced base EXACTLY (10.9/93.1/0.8) — the loop-only
+LoopLoRA guarantee holds in practice; the mechanism is validated even
+though the hypothesis died (useful for any future band-side work).
+Accuracy cells not measured (eval killed at Nils's call to save ~50min
+GPU); adapter+lora e200 checkpoints in the bucket if anyone ever wants
+the number. Verdict: with items 22+23 this closes the E2-L
+internalization line entirely — adapter capacity, training time,
+pause bandwidth, and band expressivity have all now failed to move
+the d=1 break. The carried state's native cargo (plans, magnitudes,
+completion-state — see the probe series) is the program's remaining
+asset; next candidates: divergence batch replay, coarse-target
+auxiliary supervision, A2, E2-N.
