We present the Planck Vacuum Thermal Theory (PVTT), a programme that derives five Standard Model constants from a single geometric object: the ZarembaKMS Dirac operator D_Z on S^3 (c^* )×S_β^1×A_F, where A_F=M_2 (H)⊕M_4 (C). The programme rests on an ontological inversion: the quantum vacuum KMS state ω_"KMS " is the primary object of physics; General Relativity and quantum field theory are derived low-energy descriptions, in the same way a topographic map is a derived projection of the terrain it represents.From three postulates and a unique self-consistent fixed point c^*=3/2 (determined by the spectral occupation equation M_0 (c^* )^2 N_F=π ), we derive: Newton's constant ( 5.3% ), the electroweak VEV v=243GeV ( 1.1% ), the Higgs stability boundary m_H^"stab " =129.3GeV ( <0.1GeV from the SM NNLO value), the top Yukawa y_t (Λ_UV )=0.40702(0.005%), and three fermion generations (exact, from Poincaré duality combined with the KMS phase coherence c^*=n_"gen " /2 ).Eight exact mathematical results underpin the programme: ζ_Z (0)=-1/4,det_Z=4/3,kerD_Z={0},χ_A^2=0,a_4^"corner " =1/8,n_(A_F )=47/4,G(q_6 )=227/48, and c^*=n_"gen " /2. Three open problems are precisely formulated.The 4 GeV gap between m_H^"stab " and the observed m_H^"obs " =125.25GeV is identified as a measurement of electroweak vacuum metastability at 2.3σ, not an error of the framework.
