+"""Guest ledger connections must inherit the configured database.synchronous.
+
+apply_durability_barriers() is the guest-connection entry point (secondary
+state.db users that must NOT touch journal mode). The configured
+``database.synchronous`` level normally rides on apply_database_pragmas()
+during the owner's journal-mode setup — a path guests deliberately skip — so
+the guest entry point applies it directly.
