+# Data Layer
+
+`data` owns database clients, persistence models, migrations, configuration
+watching, and repository implementations.
+
+- `repository/`: system repositories and table persistence
+- `payment/`: payment configuration and payment-order persistence
+- root files: shared database lifecycle, runtime clients, integration-config
+  storage, data-scope auditing, and migration orchestration
+
+Root files intentionally stay in one package because they share `Data` state and
+reload locks. Do not split them into packages only to reduce file count.
