+`site_id` est nullable, et c'est le coeur du schema : une ligne par site, plus une ligne
+globale tous sites confondus, que `NULL` designe. Un seul site qui derive est invisible dans

+de modele ou de saison, pas une panne.
+
+L'unicite passe par un index a `coalesce` et non par une `UniqueConstraint` : deux lignes
+globales successives ont toutes deux `site_id` a NULL, et NULL n'est egal a aucune valeur, pas
+meme a lui-meme. Meme forme que `uq_reading_source`.
+
+Les trois `CHECK` sont portees par la base, comme `ck_prediction_status` : un verdict sans
+motif, ou un statut inconnu, ne doit pas dependre de la vigilance de l'appelant.
