Balanced presentations of the trivial group and four-dimensional geometry
Bibliographic record
Abstract
We prove that: (1) There exist infinitely many nontrivial codimension one “thick” knots in [Formula: see text]; (2) For each closed four-dimensional smooth manifold [Formula: see text] and for each sufficiently small positive [Formula: see text] the set of isometry classes of Riemannian metrics with volume equal to [Formula: see text] and injectivity radius greater than [Formula: see text] is disconnected; and (3) For each closed four-dimensional [Formula: see text]-manifold [Formula: see text] and any [Formula: see text] there exist arbitrarily large values of [Formula: see text] such that some two triangulations of [Formula: see text] with [Formula: see text] simplices cannot be connected by any sequence of [Formula: see text] bistellar transformations, where [Formula: see text] ([Formula: see text] times).

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
