"""v46 -- the Grand Mass Volume: the absolute mass-scaling normalisation (check.txt
block C.3), [I] -- no product-rule hunt needed.

The absolute normalisation of the quark/fermion sector is NOT a per-coefficient
c-product (those are gauge); it is the DETERMINANT of each sector's mass matrix,
which is a clean u-power whose exponent is the sum of that sector's phi0-ladder
exponents = the corresponding K-matrix row sum:

  up-sector     det ~ u^(k_u+k_c+k_t)   = u^(4+2+0) = u^6  = u^{|R^+(A3)|}
  down-sector   det ~ u^(k_d+k_s+k_b)   = u^(4+3+2) = u^9  = u^{N_fam^2}
  lepton-sector det ~ u^(k_e+k_mu+k_tau)= u^(5+3+2) = u^10 = u^{A_Lambda}

  => Grand Mass Volume   det M_SM ~ u^(6+9+10) = u^25 = u^{g_car^2} = u^{Delta_Y}.

And the K/Q row-sum structure closes the transport budget:
  K row sums = (6,9,10) (sectors), total 25 = g_car^2 = Delta_Y,
  Q row sums = (4,5,6) = (|mu4|, g_car, |R^+(A3)|), total 15 = dim A3,
  25 + 15 = 40 = sum L = |R(D5)|  (mass volume + shift volume = transport budget).

So the absolute normalisation is the [I] determinant scaling u^25, with each sector
fixed by its K-row sum (compiler atoms).  The individual c_q stay a gauge; the
PHYSICAL invariants are the 3 cross-sector ratios (v42/v45, [I]) plus this absolute
mass-determinant scaling (v46, [I]).  No fishing, no product rule.
