Abstract
By definition, homeothermic species maintain their core temperature (Tc) regu-lated within narrow limits. In most of these species, the hypothalamic thermostat is set somewhere between 36 and 38C, and Tc is tightly kept there, in spite of highly variable ambient temperatures. Several mechanisms to maintain body temperature have been selected during evolution. Vasoconstriction and piloerec-tion are mechanisms to save heat, while vasodilatation, sweating and perspiration are mechanisms to rapidly dissipate heat. To maintain temperature in environ-ments usually colder than Tc, homeothermic species need to produce more heat than poikilothermic species. Energy transformations generate heat simply by virtue of the laws of thermodynamics and so the energy transformations inherent to life generate heat. Such heat, generated as byproduct of cell vital functions, is called obligatory thermogenesis (OT) and is expectedly higher in homeothermic species, as a consequence of which metabolic rate is substantially higher in these species than in poikilothermic species (Else and Hulbert, 1981). In addition to having a higher OT, homeothermic species can also activate specific mechanisms

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.
