Abstract
The difference between semirings and rings is the lack of additive inverses in semirings. The most common examples of semirings which are not rings are the non-negative integers ℤ+, the non-negative rationals ℚ+ and the non-negative reals ℝ+ with usual addition and multiplication. There are classical examples of non-numerical semirings as well. One of the first examples appeared in the work of Dedekind in connection with the algebra of ideals of a commutative ring (one can add and multiply ideals but it is not possible to subtract them). Later Vandiver proposed the class of semirings as the best class of algebraic structures which includes both rings and bounded distributive lattices. Boolean algebras, max-algebras, tropical semirings and fuzzy scalars are other important examples of semirings. See the monographs for more details.

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
