 Le bloc `abjection:shit_cube` reprend les propriétés de la boue, l’apparence 16×16, la recette
 neuf boules, le butin et l’outil pelle historiques. Les textes sont disponibles en français,
 anglais et russe. Only Fun reste en données v2 et protocole réseau 2 pour ABJ-01.
+
+## ABJ-02 — projectile Ouch
+
+Only Fun expose l’objet et le point d’installation `AbjectionProjectileApi`. Ouch, qui dépend
+explicitement d’Only Fun sans cycle inverse, enregistre le type d’entité sous le même ID historique
+`abjection:shit_ball` et installe la fabrique commune au lancer manuel et au dispenser. Le
+projectile mesure 0,25 bloc, consomme une unité hors créatif, joue le son de boue à l’impact et
+ajoute sept secondes à la nausée déjà présente sans dupliquer d’objet.
+
+## ABJ-03 — raccourci configurable
+
+La catégorie de contrôles Only Fun expose « Chier », assigné à `J` par défaut. Le client utilise
+`consumeClick`, puis envoie un payload vide `onlyfun:c2s/shit_action`. Le serveur accepte au plus
+une demande par joueur et par tick, revalide que le joueur est toujours connecté, vivant et non
+spectateur, puis appelle le même `AbjectionActions.start(SHIT)` que `/shit`. Maintenir la touche
+ne produit donc pas de répétition par tick et la commande reste disponible. Only Fun conserve ses
+données v2 et passe son protocole réseau de 2 à 3.
