Nukva is built separately with mitigated Strengths.
Nukva is built separately — distinct from her growing alongside Zeir Anpin (Z"A). The closing nine-chapter unit (Op. 130–138) begins.
Op. 130 marks the structural pivot from Z"A's completion to Nukva-building proper. The chapter does double duty: it concludes Op. 119–129's Z"A-construction sequence and opens the closing nine-chapter unit on Nukva's specific repair.
The Z"A-construction unit (Op. 119–123, 124–129) had Z"A and Nukva growing together. Op. 130 reveals that the together growth is only one aspect of the cosmic-operational architecture. Nukva also has her own building-process — separate from her growing alongside Z"A.
Two reasons for the separate building. First, Nukva's function is not equal to Z"A's. She is the operational receiver/distributor; Z"A is the operational source. The functional asymmetry requires structural-construction asymmetry. Second, the repair Nukva undergoes is not Z"A's growth. The cycle's deed-dependent operating mode requires Nukva to undergo specific operational repairs that her parallel growth with Z"A does not provide.
Mitigated Strengths: Nukva's gevurot (powers of judgment) are mitigated — sweetened by Imma — before they enter her structural identity. Without mitigation, Nukva would inherit raw stern judgment from Imma's Yesod (the same source as Z"A's gevurot, Op. 52); with mitigation, Nukva's strengths are operationally sweetened.
Op. 131–133 (the bracketed Ascent-and-Descent sub-section). Op. 134–138 (the deed-dependent Repair of Nukva — the closing five chapters).
