Four roads. Left: Quantity (how many). Right: Space (place). Down: Structure (pattern). Up: Change — last, most machinery. Left-to-right is quantity going into space. The middle is not a fifth road. It is what we can count inside the pile we don’t know yet.

Ring of Measure

Near Space: one width — the diameter — governs the rim. Rope around a post unlocks a length you cannot walk, the same pattern as a river you cannot tape. Open Ring of Measure, then turning on a circle.

Bridge · circle ↔ sound
Bridge · trig ↔ waves
Bridge · ring ↔ river

Click a box to open a written lesson. Locked stops on the list wait for 100% on the previous written lesson. Empty road = not written — we do not link it.

Path of discovery starts at counting in the core, then quantity to the left (times, parts), then out to a floor — quantity going into space. On the Space arm, Ring of Measure sits before the unit-circle climb: one diameter, then rim as coordinates. Stick and ship are later jobs that loop to a length you cannot reach, not the start of the path. Bridge chips mark cross-links you have met or will meet. The map is our line drawing. It is not a catalogue of every station.
