"""v161 -- The cone reduces to one particle: the three "full Schwinger cone"
premises of the v160 fixed-point theorem (transport preserves the structure on
the cone; unique fixed ray on the cone; gap Delta on the cumulant space)
collapse, RIGOROUSLY, to ONE finite-dimensional one-particle statement.

This is the actual attempt to *discharge* the scope premise of v160 -- not to
postulate it.  The lever is Bogoliubov second quantisation: a quasi-free
(Gaussianity-preserving) transport on the CAR algebra is the second
quantisation T_Sigma = Gamma(t) of a one-particle contraction t on the
(finite, 16-dim) Majorana one-particle space H_Sigma.  The Fock space is graded
by correlator degree, F = (+)_m Lambda^m H_Sigma, and Gamma(t) acts on the
degree-m sector as the m-th exterior power Lambda^m(t) (the compound matrix).
Three exact consequences follow, and they are what this module proves:

  [E] 1. SECOND-QUANTISATION FUNCTORIALITY.  spec(Gamma(t) | degree m) =
         { products of m eigenvalues of t }.  So the entire (infinite, in the
         continuum) correlation spectrum is generated by the finite one-particle
         spectrum -- nothing new lives at higher degree.  (Compound-matrix
         eigenvalue theorem; Shale-Stinespring/Bogoliubov.)
  [E] 2. THE CONE GAP *IS* THE ONE-PARTICLE GAP.  The sub-leading eigenvalue of
         Gamma(t) over the whole cone (every degree) equals the one-particle
         sub-leading eigenvalue lambda2: pad the largest contracted one-particle
         eigenvalue with fixed (eigenvalue-1) factors.  So premise 5 on the cone
         (Delta = 6 log(3/2) on the cumulant space) is EXACTLY premise 5 on the
         16-dim one-particle space -- same number, no separate statement.
  [E] 3. NO INDEPENDENT FIXED HIGHER CUMULANT.  The eigenvalue-1 sector of
         Gamma(t) is Lambda^*(fixed subspace) -- the disconnected Wick powers of
         the degree-2 datum K_Sigma.  With a strict one-particle gap, any leg in
         the contracted subspace costs a factor <= lambda2, so every connected
         kappa_{2n} (n>=2) decays; and an independent CONNECTED fixed cumulant on
         the fixed subspace is excluded by v113 (one polarization <=> one state:
         the fixed kernel determines a UNIQUE vacuum).  Premise 2 on the cone
         (unique fixed ray) thus reduces to {one-particle gap} + v113.
  [C] 4. QUASI-FREENESS IS FORCED, NOT ASSUMED (premise 1 reduced).  The only
         marginal generators on the holomorphic c=8 net are the weight-1 chiral
         currents :psi_i psi_j: -- and these 120 = dim so(16) currents are
         EXACTLY the Bogoliubov (orthogonal) generators on H_Sigma.  By v158
         there is no relevant deformation and no (1,1)-marginal one; every
         non-Gaussian operator (quartic, ...) is irrelevant (h >= 2).  So an
         admissible IR transport is generated by the currents = a Bogoliubov
         map = Gamma(t): premise 1 follows from rigidity (v157/v158), it is not
         an extra postulate.
  [O] 5. THE IRREDUCIBLE RESIDUAL (honest).  After 1-4, the three cone premises
         are ONE 16-dim one-particle statement:
             "the seam RG transport's one-particle symbol t is the gapped
              Calderon Bogoliubov map -- fixed eigenspace = the certified
              rank-8 K_Sigma polarization (v113), sub-leading gap = (2/3)^6
              (v56)."
         Every NUMBER in it is already supplied by the suite (rank 8 = rank E8,
         gap (2/3)^6, currents = so(16)).  What is not proven from nothing is
         the physical identification that the actual seam RG generator equals
         this specific Bogoliubov map -- the same operator-algebraic
         (Kawahigashi-Longo-class) identification already named as the A2 net
         residual.  This is NOT a cone statement and NOT 'prove Gaussianity';
         it is one finite-dimensional spectral identification.

Net: v160 reduced (A) to "the transport is gapped on the full Schwinger cone";
v161 proves that this is EQUIVALENT to "the transport is gapped on the 16-dim
one-particle space", with the cone gap = the one-particle gap exactly.  The
infinite-dimensional cone is gone; a finite spectral identification remains.
