Filters

Domain visibility buttons cycle gray → yellow → red: allowed, excluded from prerequisite context, then prohibited completely. Multi-domain concepts still match enabled secondary domains unless their primary domain is prohibited.

Start with a story or view

Open a curated configuration, or follow a numbered story through the graph.

Preparing the atlas…

Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.

Select a concept

Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.

Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.

Move selected concept

Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
