Abstract
A collection of systems of different composition defines a composition space which can be described by components defined as the minimum number of combinations of elements in fixed proportion required to express the composition of all phases in the considered systems. At stable equilibrium, and at constant pressure and temperature, each system is characterized by a minimum Gibbs energy G. In the space defined by the components n, there exists a minimum surface. If the compositional variation from system to system is continuous, the change of G along the minimum surface can be described in differential form by (formula) where ñi refers to components other ni. Designating the partial molar Gibbs energy of a component as G, and integrating the expression gives (formula) and division by ni leads to (formula) where G is the molar Gibbs energy and X is the mole fraction of a component. A projection of the minimum molar G surface onto the composition base, in terms of X, results in a phase diagram. 3

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
