"""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.
