Position & space
Vertical = curriculum level. Up is more advanced.
Horizontal distance is layout only — it carries no meaning.
Region = a course / grade-band family, a named zone.
Five kinds of connection
Course sequence — unit order within a course
Required prerequisite — must finish first (core)
Recommended prep — helpful, not mandatory (supporting)
Conceptual bridge — a named idea linking courses
Transfer interchange — a course hand-off node
Stations
Station — one curriculum unit
Summit — a terminus destination
