Canonical definition
A / N = (1, 2, 3, 4, 5, 6, 7, 8, 9)
B / R = (2, 6, 7, 8, 10, 12, 14, 16, 20)
C = sqrt(A² + B²)
Purpose
Permanent Reference Sets provide stable numerical anchors for geometry, ontology, syntax, and verification. They allow later work to remain comparable across versions.
Interpretive role
A supplies ordered continuity.
B supplies structured variation.
C supplies geometric linkage between A and B.
