"""v152 -- The R3 normalisation IS the dimensionful anchor (not a
separate gap): the EH coefficient produced by the replica variation is
k = ln(m/mu)/(12 pi) with mu the zeta-scale -- and ln m ALONE is
scale-ambiguous, so only the ratio m/mu is physical.  Pinning
k = c_3/2 therefore fixes a DIMENSIONLESS RATIO, m/mu = e^{3/4}, and
fixing that ratio is exactly the one dimensionful induced-gravity
anchor (v68: 1/G is UV-sensitive, Sakharov-type).  Hence R3's 'q(A_3)
normalisation' collapses into the already-declared anchor -- the count
of irreducible dimensionful anchors stays ONE.  [I] exact bookkeeping;
the anchor stays [A] (declared, not derived) and 3/4 = q(A_3) is an
audit coincidence, not a derivation.

After v150 (the gapped EH mechanism) and v151 (the Calderon kernel is
conically clean), the residual of SEAM.THEOREM.01 was '(ii) the q(A_3)
normalisation + the kernel premise'.  This module types (ii) honestly:

  [I] 1. THE COEFFICIENT IS A LOG-RATIO.  The conical part of the
         massive 2d determinant is zeta_corner(s) = C(gamma) m^{-2s}
         (v150); in any zeta-regularised determinant the scale enters
         as m^{-2s} -> (m/mu)^{-2s}, so
             Delta log det' = 2 C(gamma) ln(m/mu),
         k = ln(m/mu)/(12 pi).  The bare 'ln m' is NOT dimensionless;
         only m/mu is physical -- a determinant of a dimensionful
         operator carries its scale.
  [I] 2. PINNING k FIXES A PURE RATIO.  k = c_3/2 = 1/(16 pi)
         <=> ln(m/mu) = 12 pi c_3/2 = 3/4, i.e. m/mu = e^{3/4} ~
         2.117 -- a dimensionless gap-to-scale ratio.
  [I] 3. THAT RATIO IS THE INDUCED-GRAVITY ANCHOR.  In d = 2 the
         induced Newton constant is 1/(16 pi G) = k = ln(m/mu)/(12
         pi); fixing the ratio m/mu IS fixing 1/G in seam units
         (1/(16 pi G)|_{G=1} = c_3/2, exact).  This is the v68
         statement verbatim: 1/G is UV-sensitive (set by the
         scale-to-gap ratio), the one declared dimensionful anchor.
         So R3's normalisation is NOT a separate open item -- it is
         that anchor, in dimensionless form.
  [I] 4. ANCHOR COUNT UNCHANGED.  The residual-inventory irreducibles
         stay {one dimensionful scale, pi}: v_geo (flavour /
         amplitude, v78), the same scale read as 1/G (gravity, v68),
         and now the same scale read as m/mu (the seam EH
         normalisation) are ONE anchor in three readings -- not
         three.
  [P] 5. AUDIT (recorded, NOT promoted): the required log-ratio is
         numerically 3/4 = q(A_3) = N_fam/|mu_4|.  This is recorded
         as the target VALUE the anchor would take in seam units; it
         is NOT a derivation (a dimensionless anchor has no
         compiler-forced value -- that is the definition of an
         anchor).  SEAM.THEOREM.01 stays open [A]; what it is open
         ABOUT is now precisely 'the kernel-identification premise',
         the normalisation having merged into the standing anchor.
