"""v261 -- QFT.MSC.01: the MODULAR SPECTRAL CLOSURE -- the assembly/reduction
certificate that turns the whole TFPT QFT layer into ONE relative object reduced to
ONE open premise.  This is the structural capstone of the QFT round (v238-v260): it
does not introduce new physics, it CHECKS that the round is internally one object by
cross-validating the invariants that must agree across its parts (like v176/v234,
an assembly certificate, not a new derivation).

The master object is the relative spectral datum
    TFPT_QFT = ( A_Sigma, omega_Sigma, Delta_Sigma, rho,   # seam: algebra, KMS state, modular gen, mu4 clock
                 A_F, H_F, D_F, J, gamma,                  # carrier finite triple (v252)
                 S_rel ),                                  # relative spectral action
and the Modular Spectral Universality statement (the conditional master theorem) is:

    the unique reflection-positive, holomorphic, index-4 KMS seam state omega_Sigma
    minimises the modular clock defect, induces via the Kasparov/covariance map the
    96-dim KO-6 finite triple (D_F), whose inner fluctuations generate the gauged
    Pati-Salam spectral action with the seam KMS cutoff -- so Dirac, cutoff, gauging,
    glue and orientability are not separate choices but facets of one seam state.

  [E] 1. ONE INDEX = MARKS = FIXED POINTS = GLUE ORDER.  the Jones index
        [B:A] = 4 (v89), the simple-current/glue order |mu_4| = 4 (v92), the seam
        marks n = 2 chi(S^2) = 4 (v216), and the pillowcase/Kummer fixed points
        |(Z/2)^2| = 4 (v260) are ALL the same 4 -- one number wearing four hats.
  [E] 2. ONE CARRIER-16.  dim S+ = 2^(g_car-1) = Lambda^even(C^5) = the Kummer
        node count 2^4 = 16, and H_F = 2 * N_fam * 16 = 96 (v252/v197/v260): the 16
        is one number across spinor, lattice and triple.
  [E] 3. ONE GAP.  Delta = -log((2/3)^6) = 6 log(3/2) > 0 is simultaneously the OS
        mass gap (v240), the recovery-code rate exponent (v221) and the Lindblad
        dissipative gap (v238) -- one number, statically and dynamically.
  [E] 4. THE THREE CLOSURES RE-DERIVED (keystones, not re-asserted).
        (a) Kasparov/covariance (v258): log((1-C)C^-1) = H exactly for the KMS
            covariance C = (1+e^H)^-1 -- D_F is the induction of omega_Sigma.
        (b) KMS cutoff (v259): the seam weight f(u)=e^{-u} gives f_2/f_0 = 1 exactly
            -- the spectral-action scheme is the seam state.
        (c) K3 unification (v260): H^2(K3) = U^3 (+) E8(-1)^2, signature (3,19),
            even, det -1, E8 Cartan det 1 -- seam, carrier and lattice on one surface.
  [E] 5. THE RELATIVE-OBJECT MANIFEST.  each of the ten components of TFPT_QFT is
        realised by a built, registered script (file-existence manifest) -- the
        object is assembled, not aspirational.
  [O] 6. THE SINGLE RESIDUAL.  the entire QFT layer (admissible OS sector + boundary
        net + relative spectral action + Dirac + cutoff + gauging) reduces to the ONE
        open premise QGEO.SYM.01 (the seam realisation: the raw quasi-free seam state
        is mu_4-invariant); the ambient quantum-gravity measure QG.AMB.01 is the only
        OTHER open item and is kept separate by design (it is not a QFT blocker).
  [C] 7. MASTER STATEMENT.  Modular Spectral Universality (above) holds modulo
        QGEO.SYM.01 -- the honest sense in which the QFT layer is complete: closed as
        a relative object up to one foundational symmetry postulate, with ambient QG
        a separate monster.

Status: [E] the cross-consistency invariants + the three re-derived keystones + the
manifest (items 1-5); [O] the single structural residual (item 6); [C] the master
statement (item 7).  Python-only (assembly certificate; sympy + numpy).
