"""v145 -- The pairing values are ATOM IDENTITIES: given the exponent-
duality lift n = w0(sigma) + |mu_4| e_3 (the v139 audit identity, with
w0 = the A_3 exponent duality m <-> h-m), ALL THREE R4' pairings reduce
to atom arithmetic -- including a new clean closure |mu_4| + g_car =
N_fam^2 (4 + 5 = 9).  R4' collapses from 'derive two values' to 'derive
ONE map'.  [I] exact; the lift mechanism itself stays [P].

v142 reduced R4' to the two line pairings (|Z2|, rank E8).  This module
shows the VALUES carry no independent information once the v139 lift is
read structurally:

  [I] 1. THE LIFT IS THE EXPONENT DUALITY.  'reverse' in the v139 audit
         identity n = reverse(sigma) + |mu_4| e_3 is w0: the A_3
         exponent duality m <-> h(A_3) - m = 4 - m (swaps the Q_+
         degrees 1 <-> 3, fixes 2) -- an established Lie-theoretic
         involution (exponents pair to the Coxeter number), not an ad
         hoc permutation; the lift slot e_3 is the top-exponent
         (anchor/tau) line, the lift size is the glue order.
  [I] 2. FIRST PAIRING = GLUE/SHEET ATOM IDENTITY.
             n . 1 = sigma . 1 + |mu_4| = -|Z_2| + |mu_4| = |Z_2|
         (uses sigma.1 = -|Z_2|, v136); the value 2 says exactly
         |mu_4| = 2|Z_2| -- the glue order is the doubled sheet.
  [I] 3. SECOND PAIRING = A NEW ATOM CLOSURE.  sigma is orthogonal to
         the dual-ordered anchor:
             sigma . w0(a) = 2|Z_2| - N_fam^2 + g_car = 0
             <=>  |mu_4| + g_car = N_fam^2   (4 + 5 = 9),
         and then n . a = sigma . w0(a) + |mu_4| a_3 = 0 + 4*2 = 8 =
         rank E8: the rank pairing is the glue order times the anchor
         top entry, riding on the closure 4 + 5 = 9.
  [I] 4. THIRD PAIRING = NORM ARITHMETIC.  With ||sigma||^2 = |Z_2|^2 +
         N_fam^4 + g_car^2 = 110 = |Z_2| g_car ||Pl(K)||_1:
             n . sigma = ||sigma||^2 - N_fam^2 + |mu_4| g_car
                       = 110 - 9 + 20 = 121 = ||Pl(K)||_1^2
         -- the square the v139 selector picks is itself atom
         arithmetic of the spectral normal.
  [P] 5. RESIDUE (recorded): R4' = derive the ONE map
         n = w0(sigma) + |mu_4| e_3 (why the torsion normal is the
         exponent-dual of the spectral normal plus a glue lift on the
         top-exponent line).  All three pairing VALUES are then atom
         identities -- no independent number remains.
