Bibliographic record
Abstract
Panasqueiraite is a new mineral that occurs as a massive, fine grained pink mineral in specimens from the hydrothermal vein system at Panasqueira. Portugal. It is similar to thadeuite in association and paragenesis. Panasqueiraite is the hvdroxvl analogue of isokite and has the ideal formula CaMgPOr(OH,F). It is opticallv biaxial. positive. a 1.590(2) , P r.s96(2) , t 1.616(2),2v 5 l (2 \\ ' , b- Z, Xlrc-122". Panasqueiraite js monoclinic, a 6.535(3), b 8.753(4). c 6.9re(4) L, P rr2.33?)".

The densitv of panas-queiraite is 3.22 e cm-3 (calc.) and 3.27(1) g cm-3(obs.). Isokite and panasgueiraite are isostructural on the basis of similar chemistries and powder patterns. In the literature, the isokite cell has been described as body-centred instead of C-centred as required by the systematic pxtinctions we observed. Keywo:'ds: isokite. new mineral description. Panas-

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.
