Unification proceeds from these results toward complete material configurations, spectra, gravitational sources and measurement responses in the same system. Space Dynamics has longitudinal/transverse states, quadratic propagation, positive energy, an effective electromagnetic representation and reciprocal coupling. Matter and gravity additionally need nonlinear orientation, stable localized solutions and correct sources. A master equation must realize these under one vacuum, set of variables, action and boundaries rather than juxtapose familiar equations. Chapter 5 starts with length-dimensional $\mathbf u$ and dimensionless real $\Theta_A$, then considers independent stretch, orientation and observable tensor extensions. They are specified candidates rather than unique fundamental fields. Chapter 4's $Q\in SU(2)$ has different target-space constraints, requiring an explicit mapping. This page keeps concrete candidate calculations and their open status. A functional still needs specified coefficients, initial/boundary solutions, stable configurations and feedback spectra before becoming closed dynamics. ## The local dual-field functional Define dimensionless $s=\nabla\cdot\mathbf u$ and $\mathbf w=\nabla\times\mathbf u$. The function $F(\Theta)=\sum_A\Theta_A^2-v_0^2$ subtracts vacuum amplitude so a localized core's amplitude source tends to zero outside. It differs from the deformation matrix $F$. The manuscript uses Positive $Z_u,I_\Theta,A_\Theta$ weight displacement kinetics, order-parameter kinetics and gradients. The dimensions are $[Z_u]=\mathrm{kg\,m^{-3}}$, $[K_u]=\mathrm{J\,m^{-3}}$, $[I_\Theta]=\mathrm{J\,s^2m^{-3}}$, $[A_\Theta]=\mathrm{J\,m^{-1}}$. The speed $c_u$ is bare, before feedback. $W$ subtracts vacuum energy and permits the manuscript's $U+V_{\rm FCC}$ microscopic option. An internal orientation potential differs from spatial higher derivatives. Stabilizing and nonlinear energies remain to be specified. External generalized force density $\mathbf J_{\rm ext}$ drives the system; closed internal sources must instead evolve with their fields. For dimensionless $\mathbf T(\Theta,\nabla\Theta)$, $g_L,g_T$ are energy-density coefficients. Since curl $\mathbf w$ is axial, parity-invariant models require axial $\mathbf T$. The manuscript illustrates $$ T_i=\ell_0^2\epsilon_{ijk}C_{AB}\partial_j\Theta_A\partial_k\Theta_B,\qquad C_{AB}=-C_{BA}. $$ Here $\ell_0$ is a length and $C_{AB}$ dimensionless internal coefficients. This permits an axial structure without uniquely choosing the model or automatically defining a conserved electric current. ## Varying both fields For constant $K_u$, integration by parts and $\nabla\times\mathbf w=\nabla s-\nabla^2\mathbf u$ combine the restoring-energy variations into $-K_u\nabla^2\mathbf u$. Energy $g_LsF$ varies as $-g_L\nabla F$ and $g_T\mathbf w\cdot\mathbf T$ as $+g_T\nabla\times\mathbf T$. The Lagrangian equations then give The additional source is $\mathbf J_{\rm add}=-\delta E_{\rm add}/\delta\mathbf u$, where $E_{\rm add}=\int(\mathcal E_{\rm stab}+\mathcal E_{\rm nl})d^3x$. For each real $\Theta_A$, amplitude differentiation gives $2\Theta_A$, and gradient-dependent $\mathbf T$ requires an Euler–Lagrange derivative: Both equations use the same additional energy and $\mathcal C=\mathbf w\cdot\mathbf T$. The common functional fixes signs, factors and feedback; independently adjusting the two couplings changes the model. Homogeneous projection gives longitudinal source $g_L\nabla F$ and transverse source $-g_T\nabla\times\mathbf T$, with the remaining terms projected. Varying coefficients, independent frames or comoving derivatives require new variation and canonical momenta. These equations explicitly use partial time derivatives without an undefined transport velocity. ## Spectrum and bounded energy Positive quadratic displacement coefficients secure bare propagation, but $g_LsF$ in an ordered vacuum introduces amplitude mixing. The [wave page](/en/theory/space-dynamics/wave-propagation#ordered-vacuum) derives the longitudinal feedback speed from the same functional. A candidate must be linearized about its actual vacuum to check stable branches and common observed speed; a cubic zero-field result does not replace a nonzero-background spectrum. Without external sources or time derivatives in additional energy, momenta are $\boldsymbol\pi_u=Z_u\partial_t\mathbf u$ and $\pi_A=I_\Theta\partial_t\Theta_A$. The Hamiltonian is positive kinetic terms plus $\mathcal E_0$. Restoration and coupling complete the square: $$ \begin{aligned} \frac{K_u}{2}(s^2+|\mathbf w|^2)+g_LsF+g_T\mathbf w\cdot\mathbf T &=\frac{K_u}{2}\left(s+\frac{g_LF}{K_u}\right)^2 +\frac{K_u}{2}\left|\mathbf w+\frac{g_T\mathbf T}{K_u}\right|^2\\ &\quad-\frac{g_L^2F^2}{2K_u}-\frac{g_T^2|\mathbf T|^2}{2K_u}. \end{aligned} $$ $W$ and higher-gradient stabilizers must control the two negative terms. Quadratic amplitude $F$ needs sufficiently strong higher amplitude energy; gradient-bilinear $\mathbf T$ needs appropriate higher-gradient control. Divergence and curl remain constrained by one displacement field. Pointwise completion supplies useful sufficient checks rather than a full stability theorem. ## An interface for long-range gravity The local candidate's static response obeys $\nabla^2(K_us+g_LF)=0$. Smooth localized sources and zero far boundaries give $\sigma=g_LF/K_u$: local compression, without Chapter 2's exterior $1/r$ density or stretch potential. This concrete result calls for an extended constitutive structure rather than renaming a source. The manuscript supplies independent stretch: Dimensionless scale $\varphi$ has positive local kinetic coefficient $Z_\varphi$ and a source functional without time derivatives. It permits a $1/r$ static field and integrable gradient energy, with order-parameter feedback derived from energy $-\varphi\mathcal J_g$. Gradient-dependent sources require gradient variations; time-derivative sources require the full Legendre transformation. Independent stretch and displacement divergence are not originally the same degree of freedom. Keeping both needs constraints, coupling or scale separation to avoid double energy counting. Observable tensor modes also do not follow automatically from compatible displacement strain. Independent frames and TT channels are candidate extension requirements, not already equivalent components ready to splice together. ## Topology and stable localization For a genuine $Q\in SU(2)$ model with compatible finite-energy boundaries, Chapter 4 considers The orientation derivative $L_i=Q^{-1}\partial_iQ$ has inverse-length units. Chapter 4 uses $\|X\|^2=\operatorname{Tr}(X^\dagger X)/2$, $A_2$ in energy/length and $A_4$ in energy×length. Chapter 5's other norm and full-index sum use another normalization, so coefficients must be matched rather than copied. Global scaling at fixed orientation amplitude gives Second-gradient energy scales with size, fourth-gradient energy inversely, and nonnegative potential with volume. The first line retains Chapter 4's $Q_\lambda(\mathbf x)=Q(\mathbf x/\lambda)$. Chapter 5 (5.6.23) instead uses $\Theta_\lambda(\mathbf r)=\Theta(\lambda\mathbf r)$; replacing one scale parameter by its reciprocal gives the same condition $E_4=E_2+3E_V$. A dimensionless scale parameter is distinct from the physical radius $R$. Equations (5.6.24)–(5.6.25) then write the energy of a fixed-shape family as $E(R)=A_2R+A_4/R+A_0R^3$. Here $R>0$ is a length, $[A_2]=\mathrm{J/m}$, $[A_4]=\mathrm{J\,m}$ and $[A_0]=\mathrm{J/m^3}$. These coefficients include the chosen profile and model parameters; they are not fitted electron radii or masses. Take $A_2,A_4>0$ and first $A_0>0$. Setting $E'(R)=A_2-A_4/R^2+3A_0R^2=0$ and $x=R^2$ gives $3A_0x^2+A_2x-A_4=0$. Its left side is strictly increasing on $x>0$ and changes from negative to positive, so precisely one positive root remains. Rationalizing that root removes the subtraction of two nearly equal expressions. The rationalized expression $R_*^2=2A_4/[A_2+\sqrt{A_2^2+12A_0A_4}]$ also holds at $A_0=0$, giving $R_*^2=A_4/A_2$. The expression with denominator $6A_0$ is used only for $A_0>0$. Substitution gives zero stationarity residual, and $E''(R_*)=2A_4/R_*^3+6A_0R_*>0$. The positive stationary scale and radial stabilization mechanism therefore have an analytic expression in this scale model. A strict minimum along the scale family does not replace a solution of the complete three-dimensional field equations. Remaining work determines coefficients and shape, solves finite-energy static or periodic configurations, and checks nonradial second variations or Floquet evolution, splitting, radiation and amplitude-zero channels. Electron and proton properties must follow from that same solution, not be assigned from this radius alone. ## Matching mass, motion and measurement A localized solution must provide distinct mass definitions. Rest energy gives $M_E=E_0/c^2$; the low-speed collective action gives inertia; asymptotic stretch gives active gravitational mass; energy slope in an external stretch gives passive gravitational mass. The independent-stretch model gives After matching source integral and energy, $Z_\varphi=c^2/(4\pi G)$ is required normalization. Calibrating it with observed $G$ does not calculate that constant's microscopic origin. Inertial and passive masses still require the same solution's motion and external response; a shared spatial interpretation does not automatically equate all four masses. Next, a self-consistent moving family must include the core, internal refresh and accompanying fields, recovering the established ASD momentum/energy and directed LVE response. Chapter 5 also requires phase matching $P_i=\hbar\partial_i\Xi$, $E=-\hbar\partial_t\Xi$ for the complete dressed excitation. The phase of a slow envelope after extracting rest carrier energy describes effective energy, not the full rest energy again. The moving family then supplies mismatch sources, extended branches and envelopes before boundary/detector calculations. Effective equation forms, gravitational far fields, stable localization and readings are coordinated tasks; rewriting one familiar equation does not complete them all. ## Continuing to localized matter Existing actions expose source, feedback, energy and limiting conditions. Further work fixes coefficients, nonlinearities, target spaces and boundaries, then solves vacuum spectra, localized states and motion in the same system before instrument comparison. Existing [OP-SD-001](/en/open-problems/space-dynamics/unified-dynamics), [002](/en/open-problems/space-dynamics/equal-speed), [003](/en/open-problems/space-dynamics/stable-topology) and [004](/en/open-problems/space-dynamics/continuum-microscopic) track unified dynamics, feedback speed matching, topology and microscopic correspondence. [Wave detection](/en/open-problems/space-dynamics/longitudinal-wave-detection) and [gravitational sources](/en/open-problems/space-dynamics/source-coupling) constrain the physical interfaces. The next question is how those states form a persistent localized object. [Matter & Topology](/en/theory/matter) begins with localization and stability before particle candidates, charge, mass and spin. This page supplies its dynamical upstream, retaining both conditional results and tasks decided by actual solutions.
