Papers I–VI / G6 additive extension. The existing OMEGA_NAUGHT/1.0 contract is retained unchanged. Paper VI is added as a distinct positive-cubature component.

G6 = (SSRSD, AΩ, Dquant, Drat, Hico, Cfin, Ccub; J6)
Ccub is the positive fixed-Class-I cubature component. SRSD remains the sole frozen foundation. The tuple is a typed assembly; it does not assert that every component is derived from every other.
|Xf| = 10f² + 2. Strictly positive H₃-orbit-constant probability cubature is certified for 1 ≤ f ≤ 9. Exact degrees 5, 9, 11, 15, 17, 21, 23, 27, 29. Equivalently tf = 3f+2 (f odd) or 3f+3 (f even). The published all-frequency continuation is open for f ≥ 10.
Rank 11 with 12 orbit variables: W(t) = Wpart + t Wnull, with W333(t) = t. Complete strict-positivity domain tL < t < tU, where tL = −Wpart900 / Wnull900 and tU = −Wpart810 / Wnull810. Orientation decimals: tL ≈ 0.0261933635545922987, tU ≈ 0.0380455174948779754. Witness t = 1/27. Separate exact affine-family members maximize the minimum total orbit mass and the minimum per-node weight.
a + b√5 ↦ (a − b) + (2b/T) λ
Native field Q(√5). Inside KΩ, √5 = 2λ/T − 1. Dependency: Class-I geometry → invariant moments → Q(√5) cubature coefficients → OMEGA representation. Do not reverse this into a claim that OMEGA generates or proves the cubature theorem.
supp μf = supp νf = Xf, but generally μf ≠ νf. Paper VI reweights the same fixed Class-I nodes; it does not alter the node set.
Ds Es = id. The cubature measure may be transported losslessly by ν̂f,s = (Es)# νf. This is transport of an already-established rule, not a derivation of the cubature theorem.

CSV hashes; |Xf|; invariant systems 1≤f≤9; stored coefficients; probability normalization; strict positivity; degree sequence; omitted residuals; rank M9=11; affine family; positivity interval; t=1/27; orbit-mass max–min; per-node max–min; every Q(√5)→OMEGA translation. Certificate replay of the published CSVs is what the live runners certify. Native reconstruction of spherical moment matrices is not claimed.
G5 → G6 = G5 + Ccub + new typed interfaces, with OMEGA_NAUGHT/1.0 unchanged.
