Executive result This round produces three corrections and one new rigidity mechanism. ## Correction A — MORP-04 residual sign The primary Miller residual is $$ \boxed{ Q = P_{st} \left( (u\cdot\nabla)S + S^2 + \frac34\omega\otimes\omega \right). } \tag{1.1} $$ The MORP-04 Markdown contains one displayed definition with a minus sign in front of $$ (u\cdot\nabla)S. $$ That sign is inconsistent with Miller's primary equation and with the exact balance subsequently used. The canonical residual for all DCRP work is therefore (1.1), with the plus sign. DCRP-02 and DCRP-03 already used the plus-sign residual. Status: $$ \boxed{ \textbf{CORRECTED}. } $$ ## Correction B — scale orientation DCRP-04 used the schematic law $$ g_{SV}=\lambda^3 $$ without first distinguishing: - the physical concentration factor; - the scaling parameter actually applied by the normalization map. That distinction is necessary. For a forward singular cascade whose physical radius changes from $$ r $$ to $$ r/\Lambda, \qquad \Lambda>1, $$ the relative normalization that maps the smaller later window back to the old normalized chart uses the Navier--Stokes scaling parameter $$ a=\Lambda^{-1}<1. $$ Thus an exact normalized fixed return is naturally written $$ U \simeq \mathcal G \mathcal S_{\Lambda^{-1}} \mathcal E_\tau U, $$ not with $$ \mathcal S_{\Lambda} $$ if $$ \Lambda>1 $$ denotes the physical concentration ratio. The physical endpoint strain gain is then $$ \boxed{ \frac{ H_{\rm phys,out} }{ H_{\rm phys,in} } = \Lambda^3. } \tag{1.2} $$ The DCRP-04 positive log-debt formula remains correct when its $$ \lambda $$ is interpreted as the physical concentration factor $$ \Lambda, $$ rather than the normalization scaling parameter $$ a. $$ Status: $$ \boxed{ \textbf{NOTATION / ORIENTATION CORRECTED}. } $$ ## New rigidity mechanism For the exact residual (1.1), $$ \boxed{ \langle S,Q\rangle_{L^2}=0. } \tag{1.3} $$ This is an exact Navier--Stokes structural identity. It implies that the Cauchy--Schwarz growth direction used in the Miller cone estimate cannot be perfectly saturated by a nontrivial strain state. The resulting sharpened cone ratio is $$ \boxed{ \Theta_{SV} = \chi_{SV} \sqrt{ 1- \beta_{SV}^2 }, } \tag{1.4} $$ where $$ \chi_{SV} = \frac{ \|Q\|_2 }{ \|-\Delta S\|_2 } $$ and $$ \boxed{ \beta_{SV} = \frac{ \|S\|_{\dot H^1}^2 }{ \|S\|_2 \|-\Delta S\|_2 }. } \tag{1.5} $$ The exact strain growth satisfies $$ \boxed{ \frac12 \frac d{dt} \|S\|_{\dot H^1}^2 \le - \left( 1-\Theta_{SV} \right) \|-\Delta S\|_2^2. } \tag{1.6} $$ Hence finite-time blowup in the smooth class forces $$ \boxed{ \limsup_{t\uparrow T_{\max}} \Theta_{SV}(t) \ge1. } \tag{1.7} $$ Because $$ \Theta_{SV}\le\chi_{SV}, $$ this is strictly stronger than the unrefined cone threshold whenever $$ \beta_{SV}>0. $$ The only way to asymptotically recover the old threshold $$ \chi_{SV}\approx1 $$ is $$ \boxed{ \beta_{SV}\to0, } \tag{1.8} $$ which is exactly an unbounded spectral-dispersion regime. Thus the state-visible near-equality branch is pushed directly into a frequency-diffuse normal form. --- # 2. Normalization compiler audit MORP-01 states that a general normalization may include: - spatial translation / centering; - parabolic scaling; - pressure constants or harmonic quotient; - terminal amplitude; - footprint mass / centroid; - finite-window time origin. MORP-03 later defines the actual normalized return by $$ \mathsf T_{\rm ret} = \mathsf N_{\rm norm} \circ \mathsf E $$ and lists: - recentering; - parabolic rescaling; - pressure / harmonic quotient normalization; - terminal / reference-scale normalization; - selected-trace normalization. However, MORP-03 Section 25 gives a more restrictive statement for the **state component** of a fixed return. It assumes the state relation is generated by: 1. actual Navier--Stokes evolution; 2. parabolic rescaling; 3. normalized time translation; 4. recentering by allowed symmetry. No independent physical amplitude renormalization is present in that state relation. This distinction is necessary. --- # 3. Theorem — rigidity of state-preserving affine normalization Consider a transformation of the form $$ v(x,t) = A u(Bx,Ct), $$ $$ q(x,t) = D p(Bx,Ct), $$ with positive scalar parameters $$ A,B,C,D. $$ Assume that for every sufficiently regular solution $$ (u,p) $$ of the fixed-viscosity incompressible Navier--Stokes equation $$ \partial_tu - \nu\Delta u + (u\cdot\nabla)u + \nabla p = 0, $$ the pair $$ (v,q) $$ is again a solution of the same equation with the same viscosity $$ \nu. $$ Then necessarily $$ \boxed{ A=B, \qquad C=B^2, \qquad D=B^2. } \tag{3.1} $$ Thus the only nontrivial scalar amplitude / coordinate renormalization preserving the equation is the standard parabolic Navier--Stokes scaling. ### Proof Compute: $$ \partial_tv = AC (\partial_tu)(Bx,Ct), $$ $$ \Delta v = AB^2 (\Delta u)(Bx,Ct), $$ $$ (v\cdot\nabla)v = A^2B ((u\cdot\nabla)u)(Bx,Ct), $$ and $$ \nabla q = DB (\nabla p)(Bx,Ct). $$ For the transformed equation to be a common nonzero multiple of the original Navier--Stokes equation for arbitrary solutions, the four coefficients must agree: $$ AC = AB^2 = A^2B = DB. $$ Since $$ A,B>0, $$ the first equality gives $$ C=B^2. $$ The second gives $$ A=B. $$ Finally, $$ DB = AB^2 = B^3, $$ so $$ D=B^2. $$ Therefore the transformation is exactly $$ v(x,t) = B u(Bx,B^2t), $$ $$ q(x,t) = B^2 p(Bx,B^2t). $$ $$ \square $$ Status: $$ \boxed{ \textbf{PROVED}. } $$ --- # 4. Consequence — terminal amplitude normalization cannot be hidden in the physical state Suppose an independent terminal-amplitude normalization multiplies the state by $$ c\ne1 $$ without the coordinated spatial/time transformation required by Theorem 3.1. Then the transformed field is not, in general, another solution of the same fixed-viscosity Navier--Stokes equation. Therefore: $$ \boxed{ \textbf{ any terminal-amplitude normalization used by MORP must either} } $$ $$ \boxed{ \begin{aligned} &\text{act only on diagnostic / carrier coordinates,}\\ &\text{or be absorbed into the unique parabolic NS scaling,}\\ &\text{or else destroy actual NS state realization.} \end{aligned} } \tag{4.1} $$ This closes the hidden-amplitude ambiguity for an **actual state-visible return**. It does not prove that every MORP profile return is actually realized. That shadowing problem remains separate. --- # 5. Exact forward-window scaling orientation Let a physical singular-horizon window have radius $$ r_n $$ and define the usual normalized state by $$ u_n(y,s) = r_n u \left( x_n+r_ny, t_n+r_n^2s \right). \tag{5.1} $$ Suppose the next physical window has radius $$ r_{n+1} = \frac{ r_n }{ \Lambda_n }, \qquad \Lambda_n>1. \tag{5.2} $$ Relative to the old normalized chart, the later normalization uses the parabolic scaling parameter $$ \boxed{ a_n = \frac{ r_{n+1} }{ r_n } = \Lambda_n^{-1}. } \tag{5.3} $$ Thus a scale-fixed normalized return has the schematic forward form $$ \boxed{ U_{n+1} \simeq \mathcal G_n \mathcal S_{\Lambda_n^{-1}} \mathcal E_{\tau_n} U_n. } \tag{5.4} $$ If $$ U_{n+1}\simeq U_n, $$ then $$ H(U_n) = \Lambda_n^{-3} H( \mathcal E_{\tau_n}U_n ), $$ because $$ H( \mathcal S_aV ) = a^3H(V). $$ Therefore the physical evolution segment satisfies $$ \boxed{ \frac{ H( \mathcal E_{\tau_n}U_n ) }{ H(U_n) } = \Lambda_n^3. } \tag{5.5} $$ This is the orientation-safe form of the DCRP-04 scale-gain compatibility law. --- # 6. Primary Miller residual For the remainder of this checkpoint define $$ \boxed{ Q = P_{st} \left( (u\cdot\nabla)S + S^2 + \frac34 \omega\otimes\omega \right). } \tag{6.1} $$ Miller's exact strain equation is $$ \boxed{ \partial_tS - \Delta S - \frac12 P_{st} ( \omega\otimes\omega ) + Q = 0. } \tag{6.2} $$ The primary orthogonality identity is $$ \boxed{ \langle -\Delta S, \omega\otimes\omega \rangle = 0. } \tag{6.3} $$ Therefore: $$ \boxed{ \frac12 \frac d{dt} \|S\|_{\dot H^1}^2 = - \|-\Delta S\|_2^2 - \langle -\Delta S, Q \rangle. } \tag{6.4} $$ --- # 7. NEW THEOREM — residual-strain orthogonality ## Theorem 7.1 Let $$ u $$ be a sufficiently regular divergence-free vector field on $$ \mathbb R^3 $$ with $$ S=\nabla_{\rm sym}u $$ and $$ \omega=\nabla\times u, $$ and assume all pairings below are integrable. Let $$ Q $$ be defined by (6.1). Then $$ \boxed{ \langle S,Q \rangle = 0. } \tag{7.1} $$ ### Proof Because $$ S $$ lies in the strain space and $$ P_{st} $$ is the orthogonal projection onto that space, $$ \langle S,Q \rangle = \left< S, (u\cdot\nabla)S + S^2 + \frac34 \omega\otimes\omega \right>. $$ Since $$ \nabla\cdot u=0, $$ the transport contribution vanishes: $$ \left< S, (u\cdot\nabla)S \right> = \frac12 \int_{\mathbb R^3} u\cdot\nabla |S|^2 \,dx = 0. $$ For a trace-free $$ 3\times3 $$ matrix, $$ \operatorname{tr}(S^3) = 3\det S. $$ Hence $$ \langle S,S^2 \rangle = 3 \int \det S. $$ Miller's Proposition 1.1 gives $$ \langle S, \omega\otimes\omega \rangle = -4 \int \det S. $$ Therefore $$ \left< S, S^2 + \frac34 \omega\otimes\omega \right> = 3 \int\det S - 3 \int\det S = 0. $$ Combining the transport and algebraic terms: $$ \boxed{ \langle S,Q\rangle=0. } $$ $$ \square $$ Status: $$ \boxed{ \textbf{PROVED}. } $$ --- # 8. Immediate repair / simplification of DCRP-02 DCRP-02 proved a Model-Cone Equality Collapse theorem under the equality relation $$ Q=\Delta S. $$ Theorem 7.1 gives a shorter proof. If $$ Q=\Delta S, $$ then $$ 0 = \langle S,Q\rangle = \langle S,\Delta S\rangle = - \|S\|_{\dot H^1}^2. $$ Hence $$ \boxed{ \|S\|_{\dot H^1}=0. } \tag{8.1} $$ Thus: $$ \boxed{ Q=\Delta S \Longrightarrow \text{spatially constant strain}. } \tag{8.2} $$ In the global finite-enstrophy class, $$ S\in L^2(\mathbb R^3), $$ this gives $$ S=0. $$ Therefore the DCRP-02 equality-collapse conclusion is retained, but the proof is simplified and no comparison of two enstrophy identities is required. --- # 9. Orthogonal projection of the dissipation direction Set $$ z = -\Delta S. $$ Define $$ E = \|S\|_2^2, $$ $$ H = \|S\|_{\dot H^1}^2 = \langle S,z \rangle, $$ and $$ Z = \|z\|_2. $$ Assume $$ E>0. $$ Decompose $$ z = \frac{H}{E}S + z_\perp, $$ with $$ \langle S,z_\perp \rangle = 0. $$ Then $$ \|z_\perp\|_2^2 = Z^2 - \frac{ H^2 }{ E }. $$ By Theorem 7.1, $$ Q\perp S. $$ Therefore $$ \langle z,Q \rangle = \langle z_\perp,Q \rangle. $$ Cauchy--Schwarz now gives the strictly improved estimate $$ \boxed{ - \langle z,Q \rangle \le \sqrt{ Z^2-\frac{H^2}{E} } \, \|Q\|_2. } \tag{9.1} $$ The usual Miller cone estimate replaces the square-root factor by $$ Z. $$ The improvement is exact and comes solely from $$ Q\perp S. $$ --- # 10. Definition — spectral transversality parameter Define $$ \boxed{ \beta_{SV} = \frac{ H }{ \sqrt E\,Z }. } \tag{10.1} $$ By Cauchy--Schwarz, $$ 0\le \beta_{SV} \le1. $$ When $$ H>0, $$ one has $$ \beta_{SV}>0. $$ Also define the ordinary Miller ratio $$ \boxed{ \chi_{SV} = \frac{ \|Q\|_2 }{ Z }. } \tag{10.2} $$ Then (9.1) becomes $$ \boxed{ - \langle z,Q \rangle \le Z^2 \chi_{SV} \sqrt{ 1-\beta_{SV}^2 }. } \tag{10.3} $$ Define the **transverse cone ratio** $$ \boxed{ \Theta_{SV} = \chi_{SV} \sqrt{ 1-\beta_{SV}^2 }. } \tag{10.4} $$ Since $$ 0\le \sqrt{ 1-\beta_{SV}^2 } \le1, $$ $$ \boxed{ \Theta_{SV}\le\chi_{SV}. } \tag{10.5} $$ --- # 11. NEW THEOREM — transverse cone growth inequality ## Theorem 11.1 For every sufficiently regular nontrivial Navier--Stokes strain state for which the quantities above are finite, $$ \boxed{ \frac12 H' \le - \left( 1-\Theta_{SV} \right) Z^2. } \tag{11.1} $$ ### Proof The exact strain balance (6.4) gives $$ \frac12H' = -Z^2 - \langle z,Q \rangle. $$ Apply (10.3): $$ \frac12H' \le -Z^2 + Z^2 \Theta_{SV}. $$ Hence $$ \boxed{ \frac12H' \le - (1-\Theta_{SV})Z^2. } $$ $$ \square $$ Status: $$ \boxed{ \textbf{PROVED}. } $$ --- # 12. Corollary — strengthened blowup threshold If $$ \Theta_{SV}(t)\le1 $$ on a time interval, then $$ H(t) $$ is nonincreasing there. For a maximal $$ H^3_{df} $$ mild solution, Miller uses the standard fact that finite-time blowup implies $$ H(t) = \|S(t)\|_{\dot H^1}^2 \to\infty. $$ Therefore: $$ \boxed{ T_{\max}<\infty \Longrightarrow \limsup_{t\uparrow T_{\max}} \Theta_{SV}(t) \ge1. } \tag{12.1} $$ Equivalently, $$ \boxed{ \limsup_{t\uparrow T_{\max}} \left[ \frac{ \|Q(t)\|_2 }{ \|-\Delta S(t)\|_2 } \sqrt{ 1- \frac{ \|S(t)\|_{\dot H^1}^4 }{ \|S(t)\|_2^2 \|-\Delta S(t)\|_2^2 } } \right] \ge1. } \tag{12.2} $$ Because $$ \Theta_{SV}\le\chi_{SV}, $$ this implies the older qualitative threshold $$ \limsup\chi_{SV}\ge1, $$ but is more restrictive whenever the spectral transversality factor does not vanish. No priority / novelty claim is made here. The inequality is a direct structural corollary of Miller's exact identities. --- # 13. Quantitative gap away from spectral diffusion Suppose for all sufficiently late times $$ \boxed{ \beta_{SV}(t) \ge \beta_0 > 0. } \tag{13.1} $$ Then finite-time blowup requires $$ \Theta_{SV}\ge1 $$ along a sequence. Therefore $$ \chi_{SV} \sqrt{ 1-\beta_0^2 } \ge1 $$ along that sequence, so $$ \boxed{ \limsup_{t\uparrow T_{\max}} \chi_{SV}(t) \ge \frac{ 1 }{ \sqrt{ 1-\beta_0^2 } } > 1. } \tag{13.2} $$ Hence a blowup sequence satisfying $$ \chi_{SV}\to1 $$ must obey $$ \boxed{ \beta_{SV}\to0. } \tag{13.3} $$ This is the first direct bridge from near model-cone equality to spectral diffusion. --- # 14. NEW THEOREM — transverse logarithmic cone debt Define $$ \boxed{ \tau_{\perp}(t) = \frac{ (\Theta_{SV}(t)-1)_+ Z(t)^2 }{ H(t) }. } \tag{14.1} $$ Then Theorem 11.1 implies $$ \boxed{ \frac12 \frac d{dt} \log H(t) \le \tau_{\perp}(t). } \tag{14.2} $$ Therefore $$ \boxed{ H(t) \le H(t_0) \exp \left( 2 \int_{t_0}^{t} \tau_{\perp}(s)\,ds \right). } \tag{14.3} $$ Consequently, finite-time blowup forces $$ \boxed{ \int_{t_0}^{T_{\max}} \tau_{\perp}(t)\,dt = +\infty. } \tag{14.4} $$ for every sufficiently late $$ t_0. $$ Because $$ \Theta_{SV}\le\chi_{SV}, $$ $$ \boxed{ \tau_{\perp} \le \tau_{SV}. } \tag{14.5} $$ Thus (14.4) is a strictly sharper necessary divergence statement than DCRP-03 whenever $$ \beta_{SV} $$ is non-negligible. Status: $$ \boxed{ \textbf{PROVED}. } $$ --- # 15. Growth-time quantitative excess Suppose at some time $$ H'(t)\ge0. $$ Then Theorem 11.1 gives $$ \Theta_{SV}\ge1. $$ Hence $$ \chi_{SV} \ge \frac1{ \sqrt{ 1-\beta_{SV}^2 } }. $$ Therefore $$ \chi_{SV}-1 \ge \frac1{ \sqrt{ 1-\beta_{SV}^2 } } - 1. $$ For $$ 0\le x<1, $$ $$ \frac1{\sqrt{1-x}}-1 \ge \frac x2. $$ Taking $$ x=\beta_{SV}^2, $$ we obtain $$ \boxed{ \chi_{SV}-1 \ge \frac12 \beta_{SV}^2 } \tag{15.1} $$ at every nondecreasing- $$ H $$ time. Since $$ \beta_{SV}^2 = \frac{ H^2 }{ EZ^2 }, $$ the DCRP-03 cone debt satisfies $$ \tau_{SV} = \frac{ (\chi_{SV}-1)_+Z^2 }{ H } \ge \frac12 \frac{ H }{ E } $$ whenever $$ H'\ge0. $$ Thus: $$ \boxed{ H'(t)\ge0 \Longrightarrow \tau_{SV}(t) \ge \frac12 \frac{ \|S(t)\|_{\dot H^1}^2 }{ \|S(t)\|_2^2 }. } \tag{15.2} $$ This gives an explicit positive model-cone excess at every nontrivial strain-growth time. --- # 16. Spectral meaning of $\beta_{SV}$ Let $$ \widehat S(\xi) $$ be the Fourier transform of the strain. Define the probability measure $$ \boxed{ d\mu_S(\xi) = \frac{ |\widehat S(\xi)|^2 }{ E } \,d\xi. } \tag{16.1} $$ Let the random variable $$ X(\xi)=|\xi|^2. $$ Then $$ \mathbb E_{\mu_S}[X] = \frac HE, $$ and $$ \mathbb E_{\mu_S}[X^2] = \frac{ Z^2 }{ E }. $$ Therefore $$ \boxed{ \beta_{SV}^2 = \frac{ \left( \mathbb E[X] \right)^2 }{ \mathbb E[X^2] }. } \tag{16.2} $$ Equivalently, $$ \boxed{ \frac{ \operatorname{Var}(X) }{ \left( \mathbb E[X] \right)^2 } = \beta_{SV}^{-2}-1. } \tag{16.3} $$ Hence: $$ \boxed{ \beta_{SV}\to0 } $$ if and only if the coefficient of variation of the strain frequency-squared distribution diverges. This is not merely qualitative "high frequency". It is a precise **spectral dispersion / moment-separation condition**. --- # 17. Bounded-band lower bound Suppose $$ \widehat S $$ is supported in a frequency annulus $$ m \le |\xi|^2 \le M $$ with $$ 00. $$ Then because $$ \beta_{SV}>0, $$ $$ \Theta_{SV} = \chi_{SV} \sqrt{1-\beta_{SV}^2} < 1. $$ Theorem 11.1 gives $$ \boxed{ H'<0 } \tag{19.1} $$ whenever $$ Z>0. $$ Therefore an actual forward concentrating return with physical endpoint gain $$ H_{\rm out} = \Lambda^3H_{\rm in}, \qquad \Lambda>1, $$ cannot remain inside the closed Miller cone for the entire return interval. Equivalently: $$ \boxed{ \textbf{ every nontrivial forward scale-concentrating return must leave the closed Miller cone on a set of positive dynamical effect. } } \tag{19.2} $$ This conclusion is independent of the old equal-endpoint assumption. --- # 20. Fixed-return consequence after normalization audit Assume an actual same-history forward return shrinks physical scale by $$ \Lambda>1. $$ By Sections 3--5, if the state normalization preserves the fixed-viscosity Navier--Stokes equation, then its physical state action is symmetry-only plus the unique parabolic scaling $$ \mathcal S_{\Lambda^{-1}}. $$ If the normalized state returns to the same state modulo rotations/translations, then $$ H_{\rm phys,out} = \Lambda^3H_{\rm phys,in}. $$ Therefore: $$ \boxed{ \frac12 \log \frac{ H_{\rm phys,out} }{ H_{\rm phys,in} } = \frac32 \log\Lambda > 0. } \tag{20.1} $$ DCRP-03 then gives $$ \boxed{ \mathfrak D_{SV} \ge \frac32 \log\Lambda. } \tag{20.2} $$ The present transverse refinement gives the stronger necessary debt $$ \boxed{ \int \tau_{\perp} \,dt \ge \frac32 \log\Lambda. } \tag{20.3} $$ Thus any exact forward scale-return state must carry positive **transverse** cone debt. If a MORP equality kernel is defined so that its actual return interval has zero transverse cone debt, the fixed-return branch is immediately impossible. The remaining issue is whether the current abstract $$ \mathcal M_{SV}=0 $$ and $$ \Delta_{\rm ret}=0 $$ already imply zero interval transverse debt. That implication is not yet present in the original corpus. --- # 21. Exact status of the normalization frontier The normalization audit gives: $$ \boxed{ \text{independent state-amplitude normalization} \Longrightarrow \text{not an exact NS symmetry}. } $$ Therefore the state-visible actual-return compiler has only two legitimate possibilities. ### State-symmetry branch The state normalization is: $$ \boxed{ \text{translation} + \text{rotation} + \text{time re-root} + \text{parabolic NS scaling}. } $$ Then scale-gain compatibility is exact once the concentration/scaling orientation is declared. ### Diagnostic-normalization branch Terminal amplitude, footprint mass, selected-trace normalization, etc. act only on non-state package coordinates. They do not alter the physical state scaling law. Thus the hidden-amplitude issue is closed for actual state realization. What remains open is not amplitude compatibility. It is: $$ \boxed{ \text{profile return} \Longrightarrow \text{actual same-history return}. } $$ --- # 22. New frontier after transverse rigidity The state-visible near-model-cone branch now has a sharp dichotomy. If $$ \beta_{SV} \ge\beta_0>0, $$ then the blowup cone threshold has a uniform strict gap: $$ \chi_{SV} \ge \frac1{ \sqrt{1-\beta_0^2} } > 1 $$ along a blowup sequence. If instead the model-cone ratio approaches the old boundary: $$ \chi_{SV}\downarrow1, $$ then necessarily $$ \boxed{ \beta_{SV}\to0. } $$ By Section 16 this means: $$ \boxed{ \frac{ \operatorname{Var}_{\mu_S}(|\xi|^2) }{ \mathbb E_{\mu_S}[|\xi|^2]^2 } \to\infty. } \tag{22.1} $$ Thus the remaining equality-boundary survivor is no longer generic diffuse carrier. It is specifically: $$ \boxed{ \textbf{ unbounded strain spectral-moment dispersion. } } \tag{22.2} $$ --- # 23. Next exact proof target The next attack should focus on the one remaining state-visible route: $$ \boxed{ \beta_{SV}\to0. } $$ The most useful target is a **Moment-Reprofile Lemma**. Desired form: > If a normalized singular-return sequence has > > $$ > \beta_{SV,n}\to0, > $$ > > then either: > > 1. a positive fraction of an appropriate derivative-weighted carrier can be re-centered/re-scaled into a nonzero state-visible profile; or > 2. the high-moment tail produces a strictly positive native transition / splitting tax. The key difference from MORP-05 is that the relevant carrier should be weighted strongly enough to see the moment leakage hidden by $$ \sigma_n^{sc} \rightharpoonup \sigma_\ast^{sc}. $$ A natural derivative-weighted probability measure is $$ \boxed{ d\nu_H(\xi) = \frac{ |\xi|^2 |\widehat S(\xi)|^2 }{ H } \,d\xi. } \tag{23.1} $$ or, for the next moment, $$ \boxed{ d\nu_Z(\xi) = \frac{ |\xi|^4 |\widehat S(\xi)|^2 }{ Z^2 } \,d\xi. } \tag{23.2} $$ These are not yet inserted into the MORP cost. They are proposed as proof coordinates for the next reprofile argument. The next theorem should first test whether $$ \beta_{SV}\to0 $$ forces a nontrivial separation between $$ \nu_H $$ and $$ \nu_Z $$ that can be converted into an actual profile. --- # 24. Source audit ## Internal source findings ### MORP-01 The general symmetry-normalization list includes a possible `terminal amplitude` normalization. This is too broad to be treated automatically as a physical-state symmetry. ### MORP-03 The actual state component of a fixed return is separately described using: - Navier--Stokes evolution; - parabolic scaling; - time translation; - recentering. This is compatible with Theorem 3.1. Its displayed fixed-return relation is schematic and does not unambiguously distinguish physical concentration factor from normalization scaling parameter. DCRP-05 resolves this by using: $$ \Lambda>1 $$ for physical concentration and $$ a=\Lambda^{-1} $$ for the relative normalization scale. ### MORP-04 One displayed residual definition contains the wrong sign on the advection term relative to Miller's primary formula. All canonical DCRP work now uses (6.1). --- ## External primary source Evan Miller, *On the interaction of strain and vorticity for solutions of the Navier--Stokes equation*, arXiv:2407.02691v2. Primary facts used: $$ Q = P_{st} \left( (u\cdot\nabla)S + S^2 + \frac34\omega\otimes\omega \right), $$ $$ \partial_tS - \Delta S - \frac12P_{st}(\omega\otimes\omega) + Q = 0, $$ $$ \langle -\Delta S, \omega\otimes\omega \rangle = 0, $$ $$ \frac12 \frac d{dt} \|S\|_{\dot H^1}^2 = - \|-\Delta S\|_2^2 - \langle -\Delta S,Q \rangle, $$ and Proposition 1.1: $$ \langle S, \omega\otimes\omega \rangle = -4 \int\det S = -\frac43 \langle S^2,S \rangle. $$ The identity $$ \langle S,Q\rangle=0 $$ is derived in this checkpoint from these exact primary identities plus incompressible transport cancellation. No novelty / priority claim is made. --- # 25. End state This round closes the normalization-amplitude ambiguity for actual state-visible returns and strengthens the model-cone geometry. The main exact new identities are: $$ \boxed{ \langle S,Q\rangle=0, } $$ and $$ \boxed{ \frac12 \frac d{dt} \|S\|_{\dot H^1}^2 \le - \left[ 1- \chi_{SV} \sqrt{ 1-\beta_{SV}^2 } \right] \|-\Delta S\|_2^2. } $$ Finite-time blowup therefore requires: $$ \boxed{ \limsup \chi_{SV} \sqrt{ 1-\beta_{SV}^2 } \ge1. } $$ Near the old Miller boundary $$ \chi_{SV}\to1, $$ one must have $$ \boxed{ \beta_{SV}\to0, } $$ which is exactly unbounded spectral-moment dispersion. The next proof target is no longer generic scale diffusion. It is: $$ \boxed{ \textbf{ Moment-Reprofile Lemma for } \beta_{SV}\to0. } $$ That is the next single frontier.
