  if (!backend) {
    log_error("Failed to allocate SQLite backend");
    return NULL;
  }
 
  memset(backend, 0, sizeof(*backend));
 
  // Database handle will be set after creation by ACDS
  // This is a placeholder backend that will be initialized later
  log_debug("SQLite rate limiter backend allocated (database will be set externally)");
