"""Un nœud Condition du graphe de logique peut désormais tester une
VARIABLE GLOBALE, pas seulement un champ d'objet (voir
ensure_flow_schema.py : cond_source/cond_variable/cond_variable_chemin).
Évalué côté CLIENT (templates/play.html, evaluateConditionClause) contre
gameData.variables — exposé par full_game_payload.py, vérifié ici via
/runtime-payload. La logique JS elle-même (résolution de chemin, lecture
de gameData.variables, repli sur le comportement historique) a été vérifiée
manuellement avec Node.js (fonctions extraites de play.html) : variable
scalaire, objet avec chemin chaîné, tableau par index, variable
introuvable (ne matche rien plutôt que planter), booléen "Oui", et clause
sans "source" (comportement legacy, champ d'objet) — les 7 scénarios
passent."""
