 // - Extract unique attributes from path chain entrances to avoid duplicate queries
-// - Implement batch vs individual processing based on scope and attribute count:
-//   - Use batch mode when we have scope (limited entity IDs) or few attributes (<=1)
-//   - Use individual mode when no scope and multiple attributes to avoid loading large result sets
-//   - Refactor into smaller helper functions: extractUniqueAttributes, getScopeIds, shouldUseBatchMode,
-//     processBatchMode, processIndividualMode, queryAttributesBatch, processEntranceWithResults
-//   - Remove debug statements after optimization is tested
