Abstract
All the thermodynamic property data and phase diagrams related to solid and liquid P 2 O 5 were critically evaluated and optimized to obtain the best set of Gibbs energies for all phases. Confusion in literature data due to the very sluggish nature of the reactions involving P 2 O 5 was resolved. The Gibbs energies of O ‐ and O′ ‐ P 2 O 5 were evaluated for the first time based on the phase stability against gas. The Gibbs energy of liquid H ‐ P 2 O 5 , liquid O ‐ P 2 O 5 , and liquid O′ ‐ P 2 O 5 were also properly evaluated for the first time based on the metastable and stable vapor pressures. The calculated triple points of H ‐ P 2 O 5 , O ‐ P 2 O 5 , and O′ ‐ P 2 O 5 are 420°C and 4.600 bar, 575°C and 0.805 bar, and 580°C and 0.774 bar, respectively. The calculated polymorphic transition point between O ‐ P 2 O 5 and O′ ‐ P 2 O 5 is located at 65°C and 0.001 bar.

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
