Liberation-tower exponent ord_R(-g) = 3^(k-1): the 4-level nested daśā produces 12⁴ = 20,736 nodes — power-tower expansion matching the 3-adic liberation count at k=4.

For a parent period covering duration D, the child sub-periods traverse the SAME 12-rāśi sequence as the mahā, each rāśi taking a share proportional to its mahā-level year quantum:
At depth 4 (sūkṣma), each top-level mahā contains 12³ = 1,728 sūkṣma-nodes, and the full tree has 12⁴ = 20,736 leaves. The substrate's (ℤ/12ℤ) ring is the algebraic ground of this recursion — derivation tag (iii) period determination.
