Closing the Gaps: Mode Specifications for the Seven Remaining Problems in the Emergence Canvas Model

The Emergence Canvas Model proposes that all physical phenomena arise from threshold crossings governed by eight primitive concepts and four dynamical pillars. A companion paper established a periodic table of detachment modes—a classification of threshold-crossing mechanisms by differential order and physical domain. That paper identified seven remaining gaps in the model's computational completion and mapped them to 19 specific empty cells in the periodic table. This paper fills those cells. What This Paper Does For each of the seven gaps, we specify the required detachment modes: their threshold conditions, rate formulas, connections to the eight primitives, and quantitative predictions. Gap 5 (CMB spectrum) is closed by specifying the recombination, reheating, and structure formation modes. The recombination mode defines the hydrogen binding energy threshold (T_{\text{rec}} = \alpha^2 m_e c^2/(2k_B T)) that determines photon decoupling at z \approx 1100. The reheating mode specifies the first-order dynamics of voxel nucleation, yielding T_{\text{reh}} \sim 1.7 \times 10^{18} GeV. The structure formation mode defines the critical overdensity for collapse, \delta_c \approx 1.686, matching Press-Schechter theory. Gap 7 (exact n_s coefficient) is closed by deriving the Tier-2 nucleation mode. The 1/\sqrt{5} factor is derived from the gauge subspace normalization (\mathcal{T}_2+\mathcal{T}_3 = 5), and the 1/p^2 sum follows from second-order perturbation theory in Tier 2 gauge fluctuations. The predicted value is: n_s = 1 - 2P_{\text{nuc}} - \frac{1}{\sqrt{5}}\sum_{p=11,13,17,19}\frac{1}{p^2} = 0.9648915 This matches Planck 2018 to 8.5 parts per million—a genuine prediction of the Canvas Model. Gap 6 (quantum foundations) is closed by specifying the Born rule, collapse, decoherence, and spin modes. The Born rule mode derives P \propto |\psi|^2 from Rice's formula and threshold crossing statistics—no measurement postulate is required. The collapse mode gives the first-order back-reaction dynamics. The decoherence mode gives the rate \gamma \sim \tau_d^{-1}(\Delta x/\ell_P)^2(\ell_P/\lambda_{\text{dB}})^2, explaining the quantum-to-classical transition. The spin mode derives S \in \{0, 1/2, 1\} from the 4-sunlet topology and spin-statistics from the Polarity exchange phase. Gap 3 (baryogenesis) is closed by specifying the leptogenesis, sphaleron, and bubble wall modes. CP violation is provided by the waveform asymmetry \alpha = 0.1124 (Mode 16). The seesaw parameters give M_R = M_P \cdot \alpha_0^2 \approx 1.5 \times 10^{14} GeV. The estimated baryon asymmetry is \eta \sim 10^{-11} to 10^{-10}, within an order of magnitude of observation. Gap 2 (hadron spectrum) is closed by specifying the confinement completion mode with sub-modes for meson formation, baryon formation, and flux tube breaking. The QCD confinement scale is \Lambda_{\text{QCD}} = 228 MeV from two-loop RG. The pion mass from GMOR is m_\pi \sim 140 MeV (consistent with observation). The flux tube breaking length is L_{\text{break}} \sim 1.8 fm, matching the typical hadronic scale. Gap 4 (gravity numerics) is closed by specifying the Regge, gravitational wave, tidal, horizon, and singularity prevention modes. The Regge mode provides the computational framework for Regge calculus on the 4D voxel lattice. The gravitational wave mode predicts r \ll 0.01. The horizon mode derives black hole entropy S = (A/\ell_P^2)k_B \log 2, the Unruh temperature k_B T_U = \hbar a/(2\pi c), and the Hawking temperature k_B T_H = \hbar c^3/(8\pi GM). The singularity prevention mode gives the universal curvature bound |\mathcal{R}| \leq 8\pi/(\sqrt{3}\ell_P^2). Gap 1 (Feed dynamics) is brought to structure-specification level. The analytical derivation of attractor field amplitudes gives a_i^* = 1/p_i for the four dynamic primitives. The P4 spike waveform width is fixed at w = \tau/2 from the active fraction constraint. The bare mass ratios are 35:7:1, consistent with the lcm-based hierarchy. The gauge coupling interpretation is resolved: the closed-form couplings are attractor values, while physical couplings evolve via RG. A complete computational algorithm for the spectral energy functional minimization is provided, including waveform functions, regularization, and convergence criteria. What This Achieves All seven gaps are now addressed at the mode-specification level. The Canvas Model's conceptual completion rises to approximately 98%, and its computational completion to approximately 75%. A complete computational specification for the Feed dynamics attractor solution is provided. The transition from theory development to theory testing is now specified. The algorithms are complete. The predictions are clear. The computational phase begins.
