+### Mathematical Foundations
+
+The RQM platform is grounded in a precise mathematical layer. Before exploring the architecture, readers seeking a deeper understanding of the underlying theory can start here:
+
+- [Complete Quaternion Theory](concepts/quaternion-theory.md) — the source of truth for the SU(2) ↔ quaternion correspondence
+- [SU(2) Geometry](concepts/su2-geometry.md) — group structure of single-qubit gates
+- [Spinors and the Bloch Sphere](concepts/spinor-bloch.md) — state geometry and the Hopf fibration

 This page explains the key design ideas behind the RQM platform: why it is built as a compiler-first system, what backend abstraction means in practice, and how the canonical lowering path works.

 These are defined once in `rqm-core` and shared across the entire stack. No backend reimplements them.
