+ * supabaseNameDrift.test.ts — PR-SQL-3A: Supabase isim drift hizalaması kilidi.
+ *
+ * Eski tablo adları canlı/kanonik adlarla eşitlendi:
+ *   system_configs → runtime_policies   (superAdminService)
+ *   linking_codes  → vehicle_linking_codes (website vehicle/code API)
+ * (push_subscriptions → vehicle_push_tokens KAPSAM DIŞI: kolon paritesi yok — Web Push ≠ FCM.)
+ *
+ * Bu test: (1) davranışsal — superAdminService .from() hedeflerini açıkça kilitler;
+ * (2) kaynak-kilit — eski adların ilgili aktif kod yollarında kalmadığını doğrular (?raw).
