- Fixed DataTable row selection and event handling - Added explicit column keys to prevent auto-generated keys - Implemented row-to-flow mapping for reliable selection tracking - Converted left metrics panel to horizontal top bar - Fixed all missing FlowStats/EnhancedAnalysisData attributes - Created comprehensive Textual API documentation in Documentation/textual/ - Added validation checklist to prevent future API mismatches - Preserved cursor position during data refreshes - Fixed RowKey type handling and event names The TUI now properly handles flow selection, displays metrics in a compact top bar, and correctly correlates selected rows with the details pane.
