Backend module 

The backend module is intentionally focused on runtime administration and debugging.

Areas 

Runtime configuration
Logging and memory-related settings.
Connection tests
Tests for configured AI and vector store connection records.
Indexer status
Status information for indexer configurations and source processing.
Pipeline logs
Trace view for pipeline execution, including filtering and deletion.

Non-goals 

The backend module intentionally does not try to be a full indexing workbench. It is not designed as a preview system, old indexer execution UI, broad health check center or mass settings editor.
