Abstract

fetched live from OpenAlex

A 22-year-old man presented with a 3-week history of increased thirst, polydipsia, and polyuria. He described consuming large volumes of water and waking up multiple times throughout the night to drink and urinate. He also endorsed symptoms of fatigue and frequent headaches. Prior to this, he had been well. There was no history of diuretic use, lithium use, or renal disease. There was no prior head trauma, cranial irradiation, or intracranial pathology. He denied consumption of nutritional or protein supplements. Clinical exam revealed a well appearing young man with normal heart rate and blood pressure. Visual fields and general neurologic exam were grossly normal.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
