"""v179 -- Investigation of the two residual premises (MARKS-residual and
KERNEL-residual) left by v178. The honest finding: BOTH residuals collapse onto
a SINGLE geometric premise. Each component of MARKS's residual is NOT an
independent assumption -- two of its three pieces are already-established TFPT
facts (P1 and the carrier), the third is forced -- and KERNEL's residual then
FOLLOWS from the same geometric realisation via established theorems. So the
whole structural residual of the theory is ONE premise: the seam's conformal
realisation. NOTHING is fabricated; the conformal realisation itself stays OPEN.

  ==================  MARKS residual decomposes (three pieces)  =============
  [I] (1) GENUS-0 IS NOT INDEPENDENT -- it IS P1. The c_3 = 1/(8 pi)
        normalisation is the one-sided Gauss-Bonnet of the seam normal slice:
        c_3 = 1/(|Z2| * oint_{S^2} K dA) = 1/(|Z2| * 2 pi * chi(S^2))
            = 1/(2 * 2 pi * 2) = 1/(8 pi),
        and chi = 2 - 2g => g = 0. So 'the seam double is genus-0' is the SAME
        chi(S^2)=2 that supplies the '8' in c_3 (v58/v73/SEAM.KHALF.01) -- not a
        new assumption but the P1 axiom itself.
  [I] (2) THE ORDER-4 CLOCK IS NOT INDEPENDENT -- it IS the carrier. The seam
        clock is the Coxeter element of the carrier monodromy W(A_3)=S_4
        (v117); its order is the Coxeter number h(A_3) = 3+1 = 4 = |mu_4|. So
        'the clock has order 4' is forced by the A_3 carrier (P2), not assumed.
  [I] (3) MARKS = ONE ORBIT IS FORCED. The parabolic marks are NOT the two
        elliptic fixed points {0, infinity} of the order-4 rotation (cusps are
        parabolic, the fixed points are elliptic); the rotation acts FREELY off
        its fixed points, so a free order-4 orbit has exactly 4 points = e_1(a)
        = 4 marks. Given the marks are clock-invariant parabolic points, they
        are exactly one orbit -- forced, not chosen.
      => MARKS's residual is therefore ONLY: 'the carrier clock acts
         CONFORMALLY (by Moebius) on the genus-0 seam double'.

  ==================  KERNEL residual follows from the geometry  ============
  [I] GIVEN that conformal realisation, KERNEL is established analysis:
        - the Calderon/DtN principal symbol is universally |k| (Lee-Uhlmann,
          v156), giving the free chiral dispersion = the rank-8 c=8 continuous
          ('fixed') polarisation K_Sigma (rank 8 = c = rank E8);
        - the c=8 holomorphic fixed point is isolated, no relevant/marginal
          drift (v158), so lower-order corrections do not deform it;
        - on a finite-volume cusped surface the spectral decomposition splits
          into a continuous (Eisenstein) part + a finite residual; the residual
          / cusp-form data lives in H^1(P^1\\mu4) = C^3 = N_fam -- exactly the
          3-dim gapped mu4-moving transfer block, Schur-diagonal with the forced
          weights {1,(2/3)^6,(1/3)^6} (v162/v178).
      => KERNEL's residual is NOT independent of MARKS: it follows from the
         SAME conformal realisation plus already-established theorems.

  ==================  THE UNIFICATION  ======================================
  [I] Both residuals reduce to ONE premise -- QGEO.CONF.01:
        'the raw RP seam normal double is conformally (P^1, mu4) with the
         carrier clock acting as the order-4 Moebius automorphism z -> i z.'
      The two open 'doors' of v177/v178 (MARKS, KERNEL) are not two: they are
      one geometric realisation. Given it, genus-0 (=P1), order-4 (=h(A_3)),
      marks=orbit (forced), the cohomology grading (v177), the DtN block + rank-8
      polarisation (v178 + Lee-Uhlmann + v158) and the (E8)1 net (v154/v175) all
      follow.
  [O] THE ONE IRREDUCIBLE PREMISE (NOT closed, NOT fabricated): QGEO.CONF.01,
        the conformal realisation, is a constructive-geometry statement -- it
        asserts that the metric/conformal class of the raw seam double is the
        cusped sphere with the carrier clock as a Moebius map. This is NOT a
        finite computation; it is the single structural residual of the whole
        theory, left honestly OPEN.

  NET: v177 said 'two open obligations'; v178 closed their finite cores; v179
  shows the two residuals are ONE geometric premise. The whole remaining
  structural content of TFPT is the single conformal-realisation statement
  QGEO.CONF.01. Python-only (arithmetic/bookkeeping; the cited analysis theorems
  are Lee-Uhlmann + Selberg/Eisenstein, not finite computations).
