Row additions in the merged table (Lemma 13 via KFL, relabelled)

Row additions in the merged table (Lemma 13 via KFL, relabelled).

The following holds (Lean statement, in the scope of module Solutions.KFMTable):

theorem NLogN.KFM.kTable_rowHyp (ext : Fin E → IStmt HS (7 + E)) :
    ∃ Kc : ℝ, 0 < Kc ∧ ∀ (Isym : List Sym) {K r Z : ℕ}, 6 ≤ K → 1 ≤ r →
      80 * Z * (Z + 2) ≤ 2 ^ K →
      RowHyp Isym (kTable ext) K (100 ^ 3) r Z (KFR.PsiR r Z) (Kc * (K + 2) + 1) τ50 ∧
        0 ≤ Kc * (K + 2) + 1 ∧ Monotone (KFR.PsiR r Z) ∧ ∀ v, Z + 2 ≤ KFR.PsiR r Z v

Context. The lemma belongs to the part KFM 7: one procedure table for Lemma 12 / Prop 14 and the FM multiplier: Procedure tables are merged by renaming procedure indices (IStmt.ren id g, nlogn HRen).

Formalization Note. This lemma belongs to the item-language (IL) layer of the integer-multiplication-kappa campaign: tape-level programs (register programs over 64 item stacks of the NLogN multitape framework, definition bundles IntMul_HvdH_M_Defs1–IntMul_HvdH_M_Defs8) that implement the data-movement primitives of the OpenAI preprint Integer multiplication below $n\log n$ (field moves, row split/merge, shifts, the uniform Proposition 11 interchange, Lemma 12 with fine $O(1)$-per-element costs, Gaussian record primitives, Proposition 14 pieces) with exact list denotations from the array-model bundles IntMul_Kappa_K_Defs* and explicit cost bounds. All names refer to the definition bundles up to IntMul_Kappa_K_Defs22.
