Abstract
Philately is the study and the practice of collecting postage stamps. More than mere receipts from fees paid for postal services, the stamps are an important source of information and an efficient means of mass communication, disseminating and popularizing knowledge of different areas. The paper analyzes the stamps issued by the Brazilian Enterprise of Posts and Telegraphs (ECT), from 1997 to 2008, trying to find out if the Brazilian philately is fulfilling its role of disseminating and encouraging the conservation of national biodiversity, with emphasis on species of flora. Eight hundred and forty postage stamps were issued in the period examined, of which about a quarter is related to the subject of environmental preservation. Most of the stamps about fauna and flora portray animal species (73%), while only 27% focus on the representatives of the flora. Sixty-five percent of the plant species showed in the stamps are native to Brazil, the remainder consisting mainly of exotic fructiferous species. Due to the large number of stamps addressing to environmental preservation, it is clear that the Brazilian philately is fulfilling its role of disseminating the national biodiversity and encouraging the environmental preservation. It is suggested, however, that there is greater equality in the number of philatelic emissions about fauna and flora, and that these focus on the native species of the country.

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.
