"""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. Python-only (numpy + stdlib); no new exact-identity content for Wolfram.
