Abstract
Abstract J. Elton used an application of Ramsey theory to show that if X is an infinite dimensional Banach space, then c 0 embeds in X , ℓ 1 embeds in X , or there is a subspace of X that fails to have the Dunford–Pettis property. Bessaga and Pelczynski showed that if c 0 embeds in X *, then ℓ ∞ embeds in X *. Emmanuele and John showed that if c 0 embeds in K ( X , Y ), then K ( X , Y ) is not complemented in L ( X , Y ). Classical results from Schauder basis theory are used in a study of Dunford–Pettis sets and strong Dunford–Pettis sets to extend each of the preceding theorems. The space L w* ( X *, Y ) of w* – w continuous operators is also studied.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
