Symbiotic Infodynamic Equilibrium: An Ontology-First Consolidation of the Framework, its Derivations, and its Empirical Status

We present a consolidated account of the Symbiotic Infodynamic Equilibrium (SIE) framework. The program is built on three axioms: (A1) information is primary rather than derivative; (A2) the universe is a closed thermodynamic system; (A3) all dynamics respect Landauer bounds at local temperature. The framework's core technical construct is the "Landauer Mass Tensor", M_L = N_bits * k_B * T_local * ln(2) / c^2, which replaces static rest mass with a dynamic thermodynamic cost of refreshing localized information on an FCC substrate. Supporting constructs include the Infodynamic Shear Tensor for non-adiabatic substrate coupling, the Gompertz form for decay-driven cosmic expansion, and a two-phase principle distinguishing kinetic from inertial informational modes. A unified five-term Lagrangian follows from the principle of infodynamic stress minimization, encompassing gravity as entropic compression, matter as execution threads, electromagnetism under bit-density saturation, topological texture, and dark energy as osmotic allocation.

We report the current state of the derivation chain --- five problems (the chirally-asymmetric Wilson coefficient, strong-CP suppression, gauge-boson halving, the FCC -> SU(4) -> Standard Model path, and Yukawa compensation) have substantive structural mechanisms identified, with four remaining technical gaps honestly scoped.

Observational content, from existing corpus papers, includes: (i) SIE rotation curves fit the 175-galaxy SPARC catalog with one free parameter per galaxy (Upsilon_disk), achieving competitive goodness-of-fit against cosmologically-constrained NFW (2 parameters per galaxy) with median reduced chi-squared = 3.33 vs NFW's 1.72, BIC-preferred in 11% of galaxies strongly and 37% in total; the primary significance is that SIE's one-parameter fit remains competitive while making a zero-free-parameter prediction for the coupling a_0 = c * H_0 / 2pi; (ii) a kinematic Hubble constant H_0_kin = 73.97 km/s/Mpc from galactic data alone; (iii) the Planck spectral tilt n_s = 1 - 2/57 = 0.96491 matching at 0.003 sigma via the left-handed chiral Standard Model inventory; (iv) a bare vacuum density rho_bare approx 2.07 x 10^-27 kg/m^3 within a factor of four of the observed critical density from CKN plus Landauer with no fitted parameters; (v) a 7.85-degree CMB quadrupole-octupole bisector from FCC {111} cleavage geometry with correlation significance p < 0.001; and (vi) a framework-consistent interpretation of the Hubble tension as an observer-interior-void effect via H_local = H_global / sqrt(1 - delta_b) producing the SH0ES match for interior observers, with the caveat that a fresh Pantheon+ re-analysis rules out the predicted void gradient under the standard SH0ES-anchored analysis; the framework's defense requires a pipeline-level calculation of how interior anchoring propagates through SH0ES, which is currently outstanding.

We identify specific research tasks --- a lattice-gauge-theory calculation of the FCC Wilson coefficient, explicit Pati-Salam Higgs potential construction, derivation of the icosahedral shell selection rule, and deepening of individual Yukawa predictions --- as the concrete program for closing the framework. SIE is falsifiable on multiple fronts, including next-generation ringdown measurements, DESI high-redshift equations of state, IAXO axion searches, and LiteBIRD polarization maps.
