Pure selection algebra over a loaded SWMMModelLayer — the logic behind the toolbar's Invert Selection / Select Upstream / Select Downstream actions.

The functions here take the current selection set and return the next one; they never touch a SelectionManager themselves. That keeps the math headless-testable (see tests/gui/test_selectionops.cpp) and lets SWMMVis's slots stay thin: build → apply → log.
