Production, qualité, gestion et prix de l'eau potable (application à la ville de Nantes)
Bibliographic record
Abstract
L'eau est indispensable à la vie telle que nous la connaissons. L'homme a, entre autres, besoin de boire 1,5 litre d'eau par jour. La régie municipale de Nantes puise l'eau de la Loire à Mauves sur Loire afin de fournir de l'eau à tous les habitants de la communauté urbaine de Nantes : Sa mission est de produire et distribuer de l'eau potable en quantité suffisante et de qualité conforme à la législation française, ceci au meilleur coût. La qualité médiocre de l'eau brute et sa dureté moyenne nécessitent un traitement de " potabilisation " complet (" traitement physique, chimique poussé, affinage et désinfection "). Tout au long de son parcours, de son captage en Loire jusqu'aux robinets des usagers, des prélèvements pour analyses sont effectués sous le contrôle de la DDASS afin de vérifier sa conformité aux normes de potabilité légales. Cette étude montre que la régie municipale de Nantes remplit correctement sa mission.

How this classification was reachedexpand
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.
