+# Abjection dans Only Fun
+
+Le runtime historique GPL-3.0-or-later de `Fun/abjection` est intégré au JAR **Only Fun**. Le
+namespace `abjection` et les IDs `abjection:shit_ball` et `abjection:shit_cube` sont conservés ; le
+manifeste Only Fun fournit l’alias Fabric `abjection`, sans créer un onzième module.
+
+## ABJ-01 — actions serveur
+
+- `/piss` émet son jet pendant 15 secondes et peut activer un bouton touché ;
+- `/vomit` émet son jet pendant 8 secondes ;
+- `/shit` émet son jet pendant 6 secondes et crée régulièrement la même
+  `abjection:shit_ball` que les lots suivants ;
+- `/smoke` émet de la fumée pendant 10 secondes.
+
+`AbjectionActions.start` est l’unique API publique de déclenchement. Chaque nouvelle demande
+redémarre seulement l’action correspondante, sans dupliquer la boule initiale de `/shit`. L’état
+reste en mémoire serveur, n’est jamais sauvegardé et est supprimé à la mort, au passage spectateur
+ou à la déconnexion.
+
+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.
