 ## Supported CSV reports
 
-Files are paired using the complete prefix before `.nodes.csv` and `.edges.csv`. That prefix is the stable `report_id`; `spatial2_scheduled_no_comm.nodes.csv` therefore pairs only with `spatial2_scheduled_no_comm.edges.csv`.

 ### Raw instances

 ## Viewer and API
 
-Except for spatial3, the viewer initially fetches an aggregate operation graph unless the browser has a saved view choice. Sigma renders the graph with WebGL. Controls cover report/view/metric selection, text and tensor search, mapping filters, self edges, relayout, fitting, and motif selection. Raw nodes and edges have their own selection details and never call aggregate-only detail or mapping endpoints. Mapping panels remain available for operation aggregate edges.

 Operation expansion is a deterministic projection of the source graph. Expand selected, Expand all operations, Collapse selected operation, and Collapse all rebuild the complete display from the current expanded-operation set. An expanded operation's raw nodes replace its aggregate node, including isolated raw nodes. An aggregate edge is retained only when both endpoint operations are collapsed; otherwise its raw edges replace it with endpoints calculated from the complete expansion set. Expansion order therefore cannot leave stale endpoints or simultaneous aggregate/raw representations.
