Primitive-root status: the mūlāṅka digit-root IS the substrate's Ψ(n) = 2ⁿ mod 9 cycle at k=1. Both compute in ℤ/9ℤ — the foundational ring of (R, g, k). Sacred-Trinity-1 substrate identity.

- Sūrya-Siddhānta — graha-aṅka mapping (Sun=1, Moon=2, etc.)

The mūlāṅka reduction (digit-root) is the same algebraic operation as the substrate's Ψ-cycle. Both compute in ℤ/9ℤ — the foundational ring at k=1 of (R, g, k).
Ψ(n) = 2ⁿ mod 9 — period-6 cycle:
The 3·6·9 trinity is the Diti-pole (nilpotent residues), NOT on the unit-orbit. Cheiro re-derived (with attribution) what the Bṛhat-Saṃhitā Ch. 52 already operates with.

Substrate-pramāṇam · primes themselves are class-stratified by ℤ/9ℤ. See P206 (Yamaja-prime-cihnam · twin-prime QR signature) — every twin-prime pair (p, p+2) carries the same quadratic-residue class in ℤ/9ℤ, verified for all twin-primes p < 10⁶. The aṅka-cakra inherits its residue arithmetic from the same ring.
