Toward P≠NP: An Observer-Theoretic Separation via SPDP Rank and a ZFC-Equivalent Foundation within the N-Frame Model

Toward P=NP: An Observer-Theoretic Separation via SPDP Rank and a ZFC-Equivalent Foundation within the N-Frame Model Darren J. Edwards∗ Swansea University [email protected] December 27, 2025 Abstract We present a self-contained separation framework for Pvs. NP built in ZFC: (i) a deterministic, radius-1compilation from uniform polytime Turing computation to local constraint polynomials with polylogarithmic contextual entanglement width (CEW), (ii) a formal Width⇒Rank upper bound for the resulting SPDP matrices at matching parameters (κ, ℓ) = Θ(log n), (iii) an NP -side identity-minor lower bound in the same encoding, and (iv) a rank-monotone, instance-uniform extraction map TΦfrom the compiled P-side polynomials to the NP family. Together these yield a contradiction under P=NP . We emphasize that our contribution is a complete ZFC architecture with full proofs for the primitives and composition; community verification (and ideally machine-checked Lean formalization) remains future work. The analysis develops a correspondence between Contextual Entanglement Width (CEW)—a quantitative descriptor of computational contextuality—and SPDP rank, yielding a unified criterion for complexity separation. We prove that bounded-CEW observers correspond to polynomial-rank computations (the class P), whereas unbounded CEW corresponds to the class NP. This establishes that the exponential SPDP rank of #3SAT and related hard languages implies P =NP within the standard framework of complexity theory. Key technical components include: (1) constructive lower bounds on SPDP rank derived from Ramanujan–Tseitin expander families; (2) non-circular reduction from Turing-machine computation to low-rank polynomial evaluation; (3) a codimensioncollapse lemma ensuring that rank amplification cannot occur within polynomial resources; and (4) structural analysis showing why the framework avoids relativization, natural-proof-style largeness, and algebrization preconditions (formal barrier-scoped ∗The enhanced framework provides both classical complexity theory separation and epistemic interpretation via Contextual Entanglement Width (CEW)-bounded observers. For a deeper exploration of the N-Frame model and observer-centric approach, see Edwards’ forthcoming work “The Observer Centric Universe, Quantum Mechanics, and the Path to AGI Alignment” (Palgrave, 2026). 1 lemmas are provided in Section 43). Together, these results yield a mathematically self-contained proof architecture that reconciles classical complexity theory with an observer-theoretic model of computation, in which resource-bounded observers are characterized by their algebraic information width. Proof Architecture. This paper provides a constructive, ZFC-formalizable separation of Pand NP via the SPDP holographic framework. The argument proceeds through (i) a deterministic radius-1compilation of all polynomial-time DTMs to local constraint polynomials of polylog CEW (Theorem 84), (ii) an NP-side identity-minor lower bound establishing exponential SPDP rank (Theorem 86), and (iii) a rank-monotone block-local reduction from P-compiled polynomials to NP instances (Theorem 199). All steps are definable in first-order arithmetic and verifiable in Lean (Appendix I).

or conceptual structure. They are not used as premises in the audit-mode proof and may be skipped without affecting the logical derivation of the separation. •Variational / Lagrangian reformulations (an alternative packaging of the same inequalities). •Positivity / geometric heuristics motivating the canonical gauge/projection conventions. •Broader semantic discussion and philosophical implications. 4 Observers and Contextual Entanglement Width (CEW) 4.1 N-Frame observers An observer is a system with a designated interface, an internal state, and a bounded local update rule. The interface is the only channel through which the observer couples to an external instance. The N-Frame constraint is that the observer update is generated by a finite library of local templates, so that the observer’s interaction structure admits a canonical block decomposition. Definition 1 (N-Frame observer).An N-Frame observer at input length nis a tuple On= (Un, Vn, Zn,T, B, Π⋆), where: •Unare interface variables (instance-coupling wires); •Vnare computation/hidden variables (internal scaffolding); •Znare auxiliary tag variables (compiler bookkeeping); •Tis a finite library of local templates (radius–1gadgets); •Bis the canonical block partition induced by T; •Π⋆is the fixed Global God-Move gauge (the universal projection/normal form). 4.2 CEW as an observer-capacity invariant CEW is defined as the rank of the observer’s induced interface-coupling operator at scale (κ, ℓ)after passing to the universal gauge Π⋆. 16 Definition 2 (Contextual Entanglement Width (CEW)).Fix (κ, ℓ) = Θ(log n)and the canonical block partition Bof Definition 1. Let PO,n(u, z, v)denote the observer’s compiled polynomial encoding (defined in Section 40.4). Define CEWB κ,ℓ(O;n) := ΓB κ,ℓ(Π⋆[PO,n]) , where ΓB κ,ℓ is the SPDP rank invariant. Remark 1 (Observer meaning of the definition).CEW is the maximal sustainable interfacecoupling complexity of the observer under the universal N-Frame gauge: it measures how many independent interface-coupling degrees of freedom survive the bounded local template regime at scale (κ, ℓ). Remark 2 (CEW nomenclature: structural vs. algebraic).This paper uses “CEW” in two related but distinct senses, which we clarify here to avoid confusion: •Structural CEW (sCEW): The interface-width measure used in compiler analysis— specifically, the maximum number of block interfaces crossed by any local constraint window during compilation. This is a syntactic/combinatorial notion defined on the compiler templates. •Algebraic CEW (aCEW): The SPDP rank ΓB κ,ℓ under the universal gauge Π⋆, as in Definition 2. This is a semantic wrapper that assigns a numerical invariant to each compiled polynomial. Key bridge: For objects produced by the radius-1compiler in the diagonal basis, structural CEW ≤Rimplies algebraic CEW ≤nO(R)at parameters (κ, ℓ) = Θ(log n). This is the content of the Width⇒Rank theorem (Lemma 28). The two notions coincide up to this polynomial lifting, so we use “CEW” without qualifier when context is clear. 4.3 Observer–SPDP correspondence theorem The next theorem records that CEW is a bona fide observer invariant: it is preserved under all compiler-equivalent presentations (block permutations, admissible basis changes, and tag normalizations) used throughout the paper. Theorem 1 (CEW invariance under the N-Frame encoding regime).For any two compilerequivalent encodings of the same observer Oat length n, their CEW values coincide: ΓB κ,ℓ(Π⋆[PO,n]) = ΓB′ κ,ℓΠ⋆′[P′ O,n], for all admissible changes (B, Π⋆, P)7→ (B′,Π⋆′, P′)induced by the compiler templates. Proof. Combine the gauge invariance lemma for Π⋆(Lemma 211) with the monotonicity/invariance properties of ΓB κ,ℓ under admissible blockwise changes (Lemma 212). This theorem makes it explicit that CEW is an observer invariant rather than an artifact of a particular encoding choice. 17 5 Main theorem (single-statement form, referee-auditable) Theorem 2 (SPDP separation in the compiled (blocked) model).Fix (κ, ℓ) = Θ(log n)and the radius–1block partition Binduced by the uniform compiler templates. Field convention: The NP-side lower bound uses a coefficient-space identity minor with diagonal entries ±1, which is invertible over any field—hence no characteristic restriction is required for the lower bound. The P-side upper bound and Width⇒Rank theorem are stated over characteristic 0(or prime p > poly(n)) to ensure that multilinearization and polynomial identity arguments hold without cancellation issues. For the separation conclusion, any fixed choice of such a field suffices. Then the following three facts (proved in this manuscript) imply P=NP: 1. (P-side compiled upper bound) For every deterministic machine M∈DTIME(nc), the uniformly compiled family {PM,n}satisfies ΓB κ,ℓ(PM,n)≤nO(1). (Item (1) holds uniformly for all polynomial time bounds by the universal-machine unrolling (Section 31.1), hence applies to every L∈P.) 2. (NP-side explicit compiled lower bound) There exists an explicit uniform 3SAT witness family {Φn}such that the associated coupled clause-sheet polynomials {Q× Φn} satisfy ΓB κ,ℓ(Q× Φn)≥nΘ(log n). (The identity minor has ±1diagonal entries, so this holds over any field.) (See Theorem 120 and Lemma 81.) 3. (Instance-uniform, witness-free extraction and rank monotonicity) For every instance Φthere is an instance-uniform map TΦ(depending only on Φ, not on any witness) such that TΦ(PM′,N(Φ)) = Q× Φand ΓB κ,ℓ(TΦ(p)) ≤ΓB κ,ℓ(p)for all polynomials p. Consequently, P=NP. Proof. Assume for contradiction that P=NP . Then there exists a deterministic polynomialtime solver machine Msol for 3SAT. Fix the explicit uniform witness family {Φn}from Item (2). For each n, consider the compiled polynomial PMsol,Φnproduced by the uniform compiler at the corresponding length N(Φn). By Item (1), ΓB κ,ℓ(PMsol,Φn)≤nO(1). By Item (3), there is an instance-uniform extraction map TΦnsuch that TΦn(PMsol,Φn) = Q× Φn and ΓB κ,ℓ(TΦn(p)) ≤ΓB κ,ℓ(p)for all p. Therefore, ΓB κ,ℓ(Q× Φn) = ΓB κ,ℓ TΦn(PMsol,Φn)≤ΓB κ,ℓ(PMsol,Φn)≤nO(1), contradicting Item (2), which states ΓB κ,ℓ(Q× Φn)≥nΘ(log n). 18 Remark 3 (Load-bearing rank notion).Every P-side upper bound and every NP-side lower bound used in the separation chain is stated for the compiled/blocked SPDP rank ΓB κ,ℓ. We do not use (and do not claim) a corresponding P-side bound for the fully unblocked rank Γκ,ℓ in this manuscript. Remark 4 (Solver vs. Verifier interpretation).The solver Msol used in the P-side compilation is logically required by the P=NP assumption (NP already has polytime verifiers by definition, so “verifier” would not use P=NP). The “God as verifier” interpretation remains valid on the NP side: the God-Move reveals the verification structure (exponential SPDP rank of the clause-sheet) that bounded observers cannot perceive. Thus the solver/verifier distinction is about which machine we compile, not about the observer-theoretic framework. Remark 5 (Load-bearing rank notion).Every P-side upper bound and every NP-side lower bound used in the separation chain is stated for the compiled/blocked SPDP rank ΓB κ,ℓ. We do not use (and do not claim) a corresponding P-side bound for the unblocked rank Γκ,ℓ anywhere in the proof of the main theorem. The blocked rank ΓBis at most the unblocked rank Γ(Lemma 80), so a lower bound for ΓBis stronger than one for Γ, and an upper bound for ΓBis weaker—but the weaker P-side bound suffices because both sides of the separation use the same notion. Audit pointers (where each item is proved). Item (1) is the compiled Width⇒Rank theorem for the uniform compiler pipeline. Item (2) follows from the block-local identityminor construction for the explicit lane family (the minor is exhibited inside the compiled/blocked SPDP coordinates). Item (3) is the witness-free extraction/collapse map (“God-Move”) together with the rank-monotonicity lemma for block-local projections. Claim scope and logical status. All constructions, encodings, and proofs in this paper are carried out entirely within ZFC. No conjectural universality, genericity, or average-case assumptions are invoked. In particular, the universal P-side collapse result follows from an explicit uniform compilation of arbitrary deterministic polynomial-time computations into the SPDP framework, while the NP-side non-collapse is proved for an explicit uniform family of standard 3SAT instances under the same encoding regime. The resulting separation is therefore unconditional in the logical sense: if all stated lemmas and theorems are correct, the conclusion P=NP follows without further assumptions. As with any claim of this scope, full verification and community scrutiny are essential and ongoing. 6 Observer-capacity semantics (CEW) as an exact wrapper for SPDP rank This manuscript is written to be auditable in standard complexity-theoretic terms (polynomialtime machines, uniform reductions, and an explicit algebraic rank measure). At the same time, the motivating interpretation is observer-centric: an observer is an inference-limited system whose internal state-update capacity is bounded. The bridge between these views is exact: our observer-capacity measure (Contextual Entanglement Width, CEW) is defined to coincide with the SPDP-rank invariant of the 19 compiled polynomial encoding used in the proof. Thus, the observer framing is not an extra assumption or an informal analogy; it is a semantic wrapper for the same algebraic object used throughout. 6.1 Definition of CEW for compiled computations Fix SPDP parameters (κ, ℓ)and a compiler-induced block partition B(as defined in Section 40.4). For each input xand machine M, let PM,|x|denote the compiled polynomial encoding of Mon inputs of length |x|(Section 40.4). Definition 3 (Observer-capacity (CEW)).The Contextual Entanglement Width of an observer/machine Mat input length nis CEWB κ,ℓ(M;n) := ΓB κ,ℓ(PM,n), where ΓB κ,ℓ(·)is the SPDP rank invariant defined in Definition 10. Remark 6 (No additional hypothesis).All separation statements in this paper are proved using ΓB κ,ℓ. CEW is definitionally the same quantity. Any statement phrased in CEW is therefore logically equivalent to the corresponding SPDP-rank statement. 6.2 Equivalence lemma (CEW ≡SPDP rank) Proposition 3 (CEW is exactly SPDP rank).For every machine Mand input length n, CEWB κ,ℓ(M;n) = ΓB κ,ℓ(PM,n). Proof. Immediate from Definition 3. Remark 7 (What is “observer-centric” here?).The observer viewpoint enters through (i) the choice of a compiler that isolates an interface-relevant substate, and (ii) the induced invariants ΓB κ,ℓ that measure how much interface-coupling can be maintained under bounded local update rules. The proof itself remains purely algebraic once these objects are fixed. The N-Frame “God-Move” (informal preview). We use the term God-Move as shorthand for a canonical codimension-collapse projection ΠΦcomputed uniformly from an instance Φand fixed compiler templates. Formally (Definition 4), ΠΦis a block-local restriction/projection map satisfying ΠΦ(PM′,N(Φ)) = Q× Φand ΓB κ,ℓ(ΠΦ(p)) ≤ΓB κ,ℓ(p). In particular, ΠΦis witness-free: it depends only on Φ, not on any satisfying assignment or accepting computation. Definition 4 (N-Frame God-Move (codimension-collapse projection)).The N-Frame GodMove is the canonical block-local global projection ΠΦ:F[u, v]→F[u] 20 (computed uniformly from Φand the fixed compiler templates) obtained by: (i) restricting administrative/tableau blocks vto fixed constants, (ii) projecting to the clause-sheet blocks u, and (iii) applying a fixed block-local relabeling/basis normalization. We also refer to ΠΦ as the codimension-collapse projection. Lemma 4 (God-Move correctness and rank monotonicity).For every instance Φ, ΠΦ(PM′,N(Φ)) = Q× Φand ΓB κ,ℓ(ΠΦ(p)) ≤ΓB κ,ℓ(p). Moreover, ΠΦis instance-uniform and witness-free. The Global God-Move Gauge (Global gauge projection map) To compare Pand NP-families within one structural framework, we fix a canonical coordinate system for all compiled computations. Definition 5 (Global God-Move Gauge (Global gauge projection map)).Aglobal gauge is a canonical diagonal basis Π+=Aunder which every compiled program has radius-1 locality and acts within the same finite local type algebra Σ. This gauge choice unifies the representation of all computational families so that SPDP-rank and contextual-entanglement width are invariant under basis changes within the gauge. Log-size activation and global structure. The Global God-Move selects an activated clause-set S=S(n)⊆Φnwith |S| = Θ(log n); all other clauses are deactivated (set zC= 0). Consequently, deg(Q× Φ,S) = O(log n).Clarification: The log-size activation controls the degree of the coupled polynomial at any local interface window, but the underlying instance Φncontains Θ(n)clause blocks overall. The identity-minor lower bound (yielding rank nΘ(log n)) exploits choices across all nclause blocks via the κ-derivative construction, not just the Θ(log n)simultaneously activated clauses. The activation window determines degree; the global block count determines rank. Remark 8 (Relationship between God-move and God-Move Gauge).The N-Frame God-move ΠΦ(Definition 4) is an instance-specific projection map that extracts Q× Φfrom the compiled polynomial. The Global God-Move Gauge (Definition 5) is the universal coordinate system in which all compilations and projections take place. The God-move operates within the God-Move Gauge: the gauge fixes the basis and locality structure, while ΠΦperforms the actual codimension collapse. Intuitively, this gauge serves as a universal coordinate frame—our “God-Move”—that places deterministic and nondeterministic computations on the same geometric footing. Holographic view. To visualize how this gauge operates, we adopt a holographic view of computation in which P-computable workloads occupy a low-complexity region bounded by an SPDP collapse surface. Intuitively, when programs are compiled into radius-1 gadgets in the diagonal basis with Π+=A, their contextual entanglement width (CEW) remains small and successive SPDP derivatives span only a polynomial-size subspace—hence codimensionpruned rank stays inside the dome. By contrast, the designated hard family fnsits beyond this surface, where rank inflation is unavoidable. Figure 1 visualizes this geometry: blue 21 crosses mark representative P workloads lying inside the collapse boundary, while the red star marks fnin the bulk. The subsequent sections formalize this picture via the deterministic compiler (radius = 1, Π+=A), the width⇒rank theorem, and the Global God-Move integration (see §§2–5, Appendix E). The Global God-Move as geometric projection. More precisely, in the SPDP framework, the Global God-Move is the unique holographic projection that simultaneously minimizes contextual entanglement width (CEW) for all P-computable workloads while fixing a universal boundary beyond which collapse is no longer possible. Formally, it corresponds to the compiler configuration with radius = 1, diagonal basis, and Π+=A, where every deterministic machine maps into the same low-width manifold under the SPDP transform. In Figure 1, that configuration appears as the translucent dome—the SPDP collapse boundary or event horizon. Every blue ×inside the dome represents a workload that, under this global projection, achieves polynomial codimension-pruned rank; these are the P-side computations stabilized by the deterministic compiler. The red ⋆labeled fnlies outside the dome, in the region where the identity-minor used in the lower-bound proof cannot vanish (assuming characteristic 0 or sufficiently large p), forcing super-polynomial rank growth. The God-Move therefore corresponds to this global alignment of compiler parameters— one canonical projection Π⋆that collapses every P-workload to the minimal-rank surface while revealing fnas a point that cannot be included without violating the invariance or monotonicity lemmas (Lemma 34). Geometrically, the dome’s surface is the manifestation of that move: the universal rank-minimizing hypersurface separating the polynomial and exponential regimes. This diagram thus illustrates the Global God-Move geometrically—the unique holographic projection where all P-computable functions lie on the minimal-rank manifold (the collapse dome), and any attempt to include fnforces a jump to exponential SPDP rank, thereby geometrically separating Pfrom NP. Synthesis. Putting these pieces together: The Global God-Move arises from a single, uniform holographic projection Π⋆(radius = 1, diagonal basis, Π+=A) produced by our deterministic compiler. In this coordinate system, the Width⇒Rank theorem certifies that all P-computable workloads have polynomial codimension-pruned SPDP rank (the interior of the collapse dome). In contrast, a Ramanujan-expander Tseitin construction forces a non-vanishing identity minor at the matched parameters κ, ℓ = Θ(log n)(over char 0 or sufficiently large prime), implying super-polynomial SPDP rank for the hard family fn. A dual (Lagrangian) certificate stabilizes the non-vanishing step, while the instance-uniform extraction TΦ(Theorem 215) and our invariance lemmas ensure these bounds are compared under the same rank-monotone pipeline. Amplituhedron-style positive geometry motivates Π⋆as the global, rank-minimizing choice across Pworkloads, explaining why one projection simultaneously collapses Pyet cannot collapse fn. Therefore Π⋆exhibits a global separation—geometrically, the collapse dome versus the bulk point—which completes the proof of P=NP. Conceptual Overview: The Geometry of the Global God-Move. To see how all mathematical components fit together within this framework: This diagrammatic framework 22 (Figure 1) integrates several mathematical layers that together complete the proof strategy. The holographic compiler (radius = 1, diagonal basis, Π+=A) provides a uniform projection Π⋆that maps every deterministic computation into a shared geometric coordinate system. Within this space, the SPDP (shifted partial derivative) formalism yields the P-side Width ⇒Rank theorem: all P-computable workloads collapse to polynomial rank inside the “SPDP dome.” On the NP side, a Ramanujan-expander/Tseitin construction forces a nonvanishing identity minor at matched parameters (κ, ℓ = Θ(log n)), and over characteristic 0 (or large p) this ensures super-polynomial rank inflation. A Lagrangian dual certificate anchors this non-vanishing step, making the lower bound gauge-invariant and analytic-robust. The amplituhedron-style positive geometry then explains why the chosen projection Π⋆is globally optimal: it simultaneously minimizes contextual entanglement width (CEW) for all Pworkloads while exposing the unique boundary that NP functions cannot cross. Finally, the instance-uniform extraction TΦand rank-monotone invariance lemmas guarantee that both sides of the argument are compared under the same uniform pipeline. Collectively these ingredients define the Global God-Move—the unique holographic alignment where all P-computable functions lie on the minimal-rank manifold (the collapse dome), and any attempt to include the NP hard family fnforces rank divergence. The subsequent sections formalize each layer of this structure and assemble them into the final separation theorem. Visualization. The following conceptual figure illustrates the collapse boundary that our formal results make precise. 7 Main theorem: Observer-class separation Theorem 5 (Observer-class separation under the Global God-Move gauge).Fix (κ, ℓ) = Θ(log n)and the universal gauge Π⋆. Then the following two statements hold: 1. (Polynomial-time observers have polynomial CEW). For every deterministic polynomial-time machine M∈DTIME(nc), the induced observer OMsatisfies CEWB κ,ℓ(OM;n)≤nO(1). 2. (An explicit NP witness family has superpolynomial CEW). There exists an explicit family of NP witnesses {Φn}(e.g. Ramanujan–Tseitin / identity-minor family) such that the induced observers OΦnsatisfy CEWB κ,ℓ(OΦn;n)≥nΩ(log n). Corollary 6 (P=NP (standard complexity consequence)).If P=NP, then the NP witness family in Theorem 5(2) would be decidable by a polynomial-time machine, hence would induce a polynomial-time observer with polynomial CEW, contradicting Theorem 5(2). Therefore P=NP . This framing makes it unambiguous: the paper is “about observers”; P=NP is what complexity people care about, but it follows as a corollary of the deeper observer-capacity separation. 23 Figure 1: Computational holography: SPDP collapse and the bulk function fn. Schematic 3-D view of the SPDP collapse boundary (translucent dome) under radius = 1, diagonal basis, and Π+=A. Blue crosses depict representative P-computable workloads that remain inside the dome, where codimension-pruned rank is polynomial. The red star indicates the target hard family fnoutside the boundary, where rank necessarily inflates. This figure is conceptual; quantitative evidence appears later via the compiler, CEW bounds, and width⇒rank lemmas. 7.1 Role of the God-Move, Ramanujan expanders, the N-Frame Lagrangian, and positive geometry Global God-Move gauge Π⋆.Π⋆is the universal observer gauge: it fixes a canonical interface presentation so that CEW compares observers in the same coordinate system. Ramanujan–Tseitin / expander witnesses. Expanders provide explicit NP witnesses whose interface-coupling structure cannot be compressed by any bounded-template observer, forcing superpolynomial CEW. N-Frame Lagrangian. The Lagrangian formulation is the variational description of observercapacity collapse: it packages the same inequalities governing CEW collapse into an extremal 24 principle. Positive geometry / amplituhedron intuition. The positive-geometry language explains why the universal gauge is naturally “one-sided” (a positivity-preserving collapse): it is a geometric way to view why CEW collapses for P-observers but not for the explicit NP witness family. 0.1 Outlook: The Holographic Upper-Bound Principle Theorem 7 (Holographic Upper-Bound Principle).There exist a constant C≥1and a fixed deterministic projection ΠN(uniform per input length N) such that for every Boolean function f∈P, rkSPDPE(f); r(n)≤nO(1) for r(n) = (log n)C, κ ≤r(n). Remark 9 (Terminology).To avoid ambiguity, throughout this paper we reserve the term Global God-Move for the NP-side projection that exposes an identity minor and yields an exponential SPDP-rank lower bound (see Definition 4 and Theorem 90). The present result on the P side is therefore referred to as the Holographic Upper-Bound Principle: it establishes the polynomial SPDP-rank bound for all radius–1 compiled computations under bounded contextual width. Status. The Holographic Upper-Bound Principle (Theorem 7) is established in the nonrelativizing setting by combining: •A depth-4, logarithmic-degree simulation of any f∈Pinto a bounded-fanin circuit class; •A uniform, totally-positive projection ΠNderived from amplituhedron geometry; and •Spectral and packing properties of d-regular Ramanujan expander families [38, 39, 14], ensuring polynomial Contextual Entanglement Width (CEW) and hence polynomial SPDP rank at r(n) = (log n)C. Relativization. The Holographic Upper-Bound Principle is explicitly non-relativizing: the upper bound depends on a fixed projection ΠNand expansion properties that do not survive arbitrary oracle access. This avoids the Baker–Gill–Solovay barrier while leaving the lower bound oracle-invariant. Implication for the separation. With the Holographic Upper-Bound Principle in place, the low-SPDP property holds uniformly for all polynomial-time functions. Combined with our explicit NP-family exhibiting SPDP rank nΩ(log n)at the same r(n)(via the Global GodMove identity-minor construction), we obtain the full non-relativizing separation P=NP. 25 Table 1: Observer Frame Definition Definition A (Observer Frame) An observer frame is a triple F= (S, R, I)consisting of: 1. A structured object S(e.g., a Boolean function, polynomial, or CNF formula); 2. A resolution class Rof admissible algebraic operations such as partial derivatives, low-degree shifts, and coordinate projections that generate observable forms from S; 3. An inference operator Ithat quantifies the dimensionality of the span of forms accessible through R. In this work, the resolution class Ris fixed as the set of partial derivatives, low-degree shifts, and coordinate projections, while the inference operator Iis instantiated as the Shifted Partial Derivative Polynomial (SPDP) rank measure. For generality, however, we keep Iabstract throughout most of the theoretical development. In the N-Frame model, the term “N” denotes natural selection acting over the landscape of computational forms, while “Frame” refers to the observer frame F= (S, R, I)that bounds what can be inferred. This viewpoint reinterprets computational complexity as a theory of observer-bounded inference. For a philosophical and geometric interpretation of this inference-boundary approach, see Edwards’ work on N-Frame networking dynamics of conscious observer-self agents [3] and the comprehensive treatment in [4]. This work is motivated by the N-Frame model, which reinterprets computational complexity as a theory of observer-bounded inference. In the N-Frame view, complexity classes are defined not solely by existential quantifiers over Turing machines, but by the formal structure of what can be verified using finite algebraic criteria. Within this framework, algebraic collapse (or non-collapse) becomes a model of inferential curvature: a measure of what the observer can ”see.” The key insight is that hardness may emerge not from the platonic non-existence of small circuits, but from the semantic boundary of what bounded observers can compress and verify. Notation Throughout this paper, we use the following notation: •CEW(f)– Contextual Entanglement Width of function f •CEWlimit(n)– Maximum CEW on inputs of length n •rks(p)or SPDP-rank(p)– SPDP-rank of polynomial p •Mℓ,p – Shifted partial derivative matrix at order ℓ 32 •ρs∗– Universal restriction map with seed s∗ •ev(f)– Evaluation vector of function f Note: We use CEWlimit uniformly throughout (replacing ad-hoc names like w(n)). 8.3 Foundational Definitions (ZFC-Level Primitives) Definition 15 (Shifted–Partial–Derivative rank).Let p∈F[x1, . . . , xn]and κ, ℓ ≥0. Define Γκ,ℓ(p) := dimFSpan{m·∂Sp|S⊆[n],|S|=κ, m monomial,deg(m)≤ℓ}. Equivalently, form the SPDP matrix Mκ,ℓ(p)whose rows are the coefficient vectors of all m·∂Spwith |S|=κand deg(m)≤ℓ; then Γκ,ℓ(p) = rankFMκ,ℓ(p). Explicit matrix construction. For complete formal specification, the SPDP matrix Mκ,ℓ(p)has: •Row indices: Pairs (S, m)where S⊆[n]with |S|=κand mis a monomial with deg m≤ℓ. •Column indices: All monomials in the standard monomial basis of F[x1, . . . , xn]. •Entry at (S, m): The coefficient vector of m·∂Spwhen expanded in the monomial basis. In ZFC terms: Mκ,ℓ(p)is a finite matrix with entries in F, and its rank is computed via Gaussian elimination (or any equivalent algorithm decidable in ZFC). Ambient convention. Throughout, we take the ambient coefficient basis to be the Boolean/- multilinear monomial basis modulo ⟨x2 i−xi⟩, i.e. columns are indexed by multilinear monomials of degree ≤D:= max{0,deg(p)−κ+ℓ}(the basis Bκ,ℓ of the codimension note). CEW scale. Our deterministic compiler has per-access CEW =O(log log N)and, across any poly(n)accesses, global CEW ≤C(log n)cfor absolute constants C, c > 0. We therefore instantiate R:= C(log n)cin the Width⇒Rank bound below (Lemma 16). Lemma 16 (CEW bound for the sorting-network compiler).Let NNbe a Batcher odd–even merge sorting network on Nwires, realized by radius-1comparator tiles in the holographic compiler. Suppose each primitive tile touches at most b∈Nblock interfaces and each comparator involves at most ∆∈Nsuch tiles. Then for every time step tlying inside a comparator layer of NNwe have CEW(t)≤2b∆. If the tag/update phases between comparator layers are implemented by radius-1NC1circuits of depth O(log log N)touching at most c0interfaces per layer, then there is a constant C > 0 such that for all twe have CEW(t)≤Clog log N. 33 In particular, across any polynomial number of accesses the compiled program satisfies CEW(p)≤ C(log N)cfor some absolute constants C, c > 0. Proof. Fix a comparator layer Lin the sorting network and consider an arbitrary vertical cut through the wire array (equivalently, a partition of the wires into left and right sets). In a Batcher odd–even merge network, each layer consists of disjoint comparators (each wire participates in at most one comparison per layer). For any vertical cut, the number of comparators whose endpoints straddle the cut is at most O(log N): this is a standard property of the Batcher network’s recursive structure, where merge layers interleave at most O(log N)pairs across any partition boundary. By assumption each comparator is implemented by at most ∆primitive tiles, and each tile touches at most bblock interfaces in the diagonal basis. Therefore, at the time step t corresponding to the execution of this layer, the total number of interfaces touched across the cut is at most O(log N)·∆·b=O(b∆ log N). Since band ∆are absolute constants, we obtain CEW(t) = O(log N)on comparator layers. Now consider a tag/update phase implemented by a radius-1NC1circuit of depth O(log log N). Each gate in such a circuit acts on a constant-size neighborhood of wires and hence, in the diagonal basis, touches at most b′=O(1) interfaces. At each depth-d layer of the circuit, the fan-out is bounded and the number of simultaneously active gates intersecting any cut is at most a constant c0(depending only on the compiler, not on N). Thus for every time step inside a tag/update phase we have CEW(t)≤c0b′≤C0 for some absolute constant C0. The total number of tag/update layers per access is O(log log N), but CEW(t)is defined as a maximum over time, not a sum, so we still have CEW(t)≤C0 on those phases. Combining the two cases: comparator layers contribute O(log N)and tag/update phases contribute O(1). Hence we obtain a uniform bound CEW(t)≤C1log N for all time steps twithin a single access, where C1depends only on b, ∆and the NC1implementation. Finally, note that composing a polynomial number of such accesses preserves a polylogarithmic bound on CEW; more precisely, there exist constants C, c > 0such that CEW(p)≤C(log N)cfor the compiled polynomial p. This is the claimed bound. 9 Polynomial Width⇒Rank via Constant-Type Profiles 9.1 Profile compression and the Width⇒Rank bound This subsection isolates the combinatorial bridge that prevents a naive (log n)O(κ)blow-up when κ= Θ(log n)and yields a polynomial Width⇒Rank conclusion. 34 Setup: compiled local-width windows and interface types. Fix a compiled localwidth model with at most Rsimultaneously live interfaces. A length-κwindow consists of κprimitive local updates. The compiler assumption is that each interface’s net effect over the window reduces to a normal form chosen from a finite set Tof types, where m:= |T| =O(1). (Equivalently: there is a confluent terminating rewrite system on local update words, producing unique O(1)-length normal forms, hence only O(1) possible types.) Definition 16 (Interface-anonymous profiles).At any time in the window, each live interface acarries a type τ(a)∈ T. The profile is the histogram h:T → {0,1,2, . . . , R}given by h(τ) := {a:τ(a) = τ},so that X τ∈T h(τ)≤R. Let H(R)be the set of all profiles realizable by some length-κwindow execution (for arbitrary κ). Lemma 17 (Profile compression removes κ-dependence).With notation as above, |H(R)| ≤ R+m m=RO(1). In particular, the number of realizable profiles depends polynomially on Rand is independent of the window length κ. Proof. Every realizable profile is a function h:T → {0,1, . . . , R}satisfying Pτh(τ)≤R. Thus H(R)is contained in H(R) := nh:T → {0,1, . . . , R}:X τ∈T h(τ)≤Ro, so |H(R)| ≤ |H(R)|. Let m=|T|. Introduce a slack variable s:= R−X τ∈T h(τ)∈ {0,1, . . . , R}. Then choosing h∈ H(R)is equivalent to choosing nonnegative integers {h(τ)}τ∈T and s satisfying X τ∈T h(τ) + s=R. By the stars-and-bars formula, the number of such weak compositions of Rinto m+ 1 parts is R+m m. Hence |H(R)|=R+m m,and therefore |H(R)| ≤ R+m m=RO(1) because m=O(1) is a constant. No quantity here depends on κ. Corollary 18 (Polynomially many profiles when R= polylog(n)).If R≤C(log n)c, then |H(R)| ≤ (log n)O(1) =no(1). Proof. From Lemma 25, |H(R)| ≤ R+m m≤(R+m)m, and m=O(1), hence |H(R)| ≤ RO(1). Substituting R≤C(log n)cgives |H(R)| ≤ (log n)O(1) =no(1). 35 Why naive counting fails. If one instead counts ordered step sequences of length κ, one typically obtains a bound (log n)O(κ). In the regime κ= Θ(log n), (log n)O(κ)= (log n)O(log n)=eO((log n)(log log n)) =nO(log log n), which is super-polynomial. Lemma 25 is precisely the bridge that replaces ordered sequences by κ-independent profiles. Diagonal-basis / block-factorable model for within-profile row spans. We now state and prove the within-profile dimension bound needed for the final Width⇒Rank theorem. This is the mathematical content of the “diagonal-basis” assumption: within a fixed profile h, the corresponding SPDP rows lie in a low-dimensional subspace whose dimension depends polynomially on R(and hence polylogarithmically when R= polylog(n)). Definition 17 (Profile subspaces via symmetric tensor powers).Fix ℓ≥0and a polynomial pin the SPDP construction. We say the coefficient representation is block-factorable if: For each type τ∈ T there exists a finite-dimensional vector space Wτ(over the base field) of dimension dτ=O(1) such that each interface of type τcontributes a vector in Wτ, and the contribution of a multiset of interfaces of type τlies in the symmetric tensor power Symh(τ)(Wτ). Define the profile space Vh:= O τ∈T Symh(τ)(Wτ). Lemma 19 (Within-profile span dimension).For each profile h, dim Vh≤Y τ∈T h(τ) + dτ−1 dτ−1≤(R+ 1)Pτ(dτ−1) =RO(1). If R≤C(log n)cand all dτ=O(1), then dim Vh≤(log n)O(1). Proof. A standard fact is that for a vector space Wof dimension d, dim Symt(W) = t+d−1 d−1. Applying this to each factor Symh(τ)(Wτ)yields dim Vh=Y τ∈T dim Symh(τ)(Wτ) = Y τ∈T h(τ) + dτ−1 dτ−1. Since 0≤h(τ)≤R, each binomial coefficient is at most R+dτ−1 dτ−1≤(R+ 1)dτ−1, hence dim Vh≤Y τ∈T (R+ 1)dτ−1= (R+ 1)Pτ(dτ−1) =RO(1), because Pτ(dτ−1) = O(1) (there are m=O(1) types and each dτ=O(1)). If R≤C(log n)c this becomes (log n)O(1). 36 Row decomposition by profiles. Let Mκ,ℓ(p)denote the SPDP matrix for pat parameters (κ, ℓ), in the standard coefficient basis. Each row corresponds to an operator of the form ∂α(xβp)with |α|=κand |β| ≤ ℓ. Under the compiled local-width model, each such row is determined (up to interface renaming) by a profile htogether with constant-size local choices inside each type. Consequently, rows of profile hlie in the profile space Vh. Formally, write Rhfor the set of rows of Mκ,ℓ(p)having profile h. Then RowSpan(Rh)⊆Vh. Therefore, RowSpan(Mκ,ℓ(p)) ⊆X h∈H(R) Vh. Theorem 20 (Width⇒Rank bound (polynomial via profile compression)).Under the compiler construction (Section 40.4), the following hold: 1. (Bounded types) |T | =m=O(1) as in Definition 16; 2. (Width bound) the number of live interfaces is at most Rthroughout; 3. (Within-profile span bound) Lemma 27 applies, so RowSpan(Rh)⊆Vhand dim(Vh)≤ RO(1) (indeed (log n)O(1) when R= polylog(n)). Then the SPDP rank satisfies Γκ,ℓ(p) = rank(Mκ,ℓ(p)) ≤X h∈H(R) dim Vh≤ |H(R)|·RO(1) =RO(1). In particular, if R≤C(log n)c, then Γκ,ℓ(p)≤(log n)O(1). Proof. By subadditivity of dimension under sums of subspaces, rank(Mκ,ℓ(p)) = dim RowSpan(Mκ,ℓ(p)) ≤dimX h∈H(R) Vh≤X h∈H(R) dim(Vh). Lemma 25 gives |H(R)| ≤ RO(1) and Lemma 19 gives dim(Vh)≤RO(1), uniformly in h. Thus rank(Mκ,ℓ(p)) ≤ |H(R)|·RO(1) =RO(1). If R≤C(log n)cthen RO(1) = (log n)O(1). Key point (what makes it polynomial). The bound is polynomial because the profile count |H(R)|is independent of κ(Lemma 25). If one instead classified rows by ordered step sequences, one gets (log n)O(κ)and in the regime κ= Θ(log n)this becomes nO(log log n), destroying the polynomial conclusion. 37 9.2 Compiler properties used in the Width⇒Rank bound We work with the deterministic holographic compiler in the diagonal basis with Π+=A, radius 1, and an instance-uniform access schedule. The following are properties of the compiler construction (not extra hypotheses): (P1) Radius-1 locality. Each primitive operation (gate/tile) touches at most b∈Nblock interfaces, where b=O(1) depends only on the compiler. (P2) Finite local alphabet. In the diagonal basis with Π+=A, the effect of a primitive operation on a single interface is determined by a local type τ∈Σ; the alphabet size |Σ|=S=O(1) is an absolute constant (e.g., comparator role, wire parity, SoS tile role). (P3) CEW bound. At every step, at most Rinterfaces are live (Contextual Entanglement Width), with R=C(log n)cfor absolute constants C, c > 0(see Lemma 16). (P4) SPDP parameters. We use derivative order κand degree guard ℓwith κ, ℓ = Θ(log n). (P5) Diagonal-basis / profile-subspace structure. We work in the diagonal local basis and fix the block-local map Π+=A. Lemma 27 proves that for each interface type τ∈Tthere exists a constant-dimensional space Wτ(dimension dτ=O(1)) such that, for every interface-anonymous profile h, all SPDP rows arising from canonical windows of profile hlie in the subspace Vh:= O τ∈T Symh(τ)(Wτ). Consequently, dim Vh≤RO(1) (and hence dim Vh≤(log n)O(1) when R≤C(log n)c). All hidden constants depend only on the compiler and not on n, κ, ℓ. 9.3 Canonical windows, normal forms, and profiles Alength-κwindow is a sequence of κsuccessive directional derivatives applied to the compiled program. We pass to canonical representatives via the following rules. (P6) Commutation on disjoint support. If two derivative steps act on disjoint interface sets, their order is immaterial; windows differing only by commuting such steps are identified. (P7) Canonical local update normal form. Fix an interface type τ. In the diagonal basis, each local symbol a∈Στacts as a fixed linear operator on a constant-dimensional interface space Wτ. Let Mτ⊆End(Wτ)be the (finite) monoid generated by these operators. Define NFτ: Σ∗ τ→Σ≤qτ τto map any word to the shortlex-least word that represents the same monoid element in Mτ. Since |Mτ|=O(1) (compiler-fixed), every monoid element has a representative of length at most qτ≤ |Mτ|−1 = O(1). In a canonical window, every maximal interface-local update subword is replaced by its NFτ(·)normal form. 38 9.3.1 Canonicalization map and row-span preservation Let Winκdenote the set of block-admissible length-κwindows in the compiled/radius–1 regime (as used in the Width⇒Rank analysis). Definition 18 (Canonicalization map can(·)).Define can : Winκ→Winκby the following deterministic procedure: 1. (Disjoint-support commutation normal form). Reorder the κderivative steps by repeatedly swapping adjacent steps whose interface supports are disjoint, until the window is in the fixed lexicographic order on the triple (block index,interface id within block,time index). This implements convention (P6) and yields a unique representative of each commutation class. 2. (Local word normal form). For each live interface e, let σe(w)∈Σ∗be the interfacelocal update word induced by the window w. Replace σe(w)by its monoid normal form NF(σe(w)) as in convention (P7), and rebuild the corresponding window representation. Let Wincan κ:= can(Winκ)be the set of canonical windows. Lemma 21 (Local update words act only through the finite monoid).Work in the diagonal local basis (with the fixed block-local normalization Π+=A). Each symbol τ∈Σinduces a fixed interface-local linear action Aτon the constant-dimensional interface tensor factors used to form SPDP rows. Extend multiplicatively to words: for u=τ1···τt, set Au:= Aτt···Aτ1. (Compiler note.) Here “interface” means the bounded set of boundary variables shared between adjacent blocks/cells in the fixed block partition B(a circuit/constraint interface), not a perceptual interface. If two words u, v ∈Σ∗represent the same element of the finite transformation monoid M ⊆ ΣΣ, then Au=Av. In particular Au=ANF(u). Lemma 22 (Canonical windows reduction is row-span preserving).Let pbe any polynomial in the compiled regime, and let MB κ,ℓ(p)be the blocked SPDP matrix (Definition 10, block-local specialization). For each window w∈Winκ, let row(w)denote the corresponding SPDP row vector (i.e. the coefficient row indexed by the induced derivative/shifting choice). Then for all w∈Winκ, row(w) = row(can(w)). Consequently, RowSpanMB κ,ℓ(p)= span{row(w) : w∈Wincan κ},and hence ΓB κ,ℓ(p)is unchanged by restricting to canonical windows. Proof. Step (P6) only swaps adjacent derivative steps whose interface supports are disjoint. In the SPDP row construction, disjoint-support steps act on disjoint variable/interface tensor factors, hence commute and do not change the resulting coefficient row. Step (P7) replaces each interface-local update word σe(w)by NF(σe(w)) representing the same monoid element in M. By Lemma 21, the induced interface-local action on the diagonal-basis tensor factors is identical. Since the global SPDP row is built by composing/tensoring these local actions across blocks/interfaces, the full row vector is unchanged. 39 For a canonical window, each live interface eexperiences a (possibly empty) sequence of local-type changes of length at most q, drawn from the finite set Σ≤q:=Sq j=0 Σj.Interface identities are not recorded: Definition 19 (Interface-anonymous profile).The profile of a canonical window is the histogram h: Σ≤q→Nthat counts, for each local type word σ∈Σ≤q, the number of live interfaces whose local normal form equals σ. Thus Pσh(σ)≤R. Lemma 23 (Permutation-invariance within blocks).If two canonical windows differ only by a permutation of interface identities within the same block partition, then their SPDP row sets are related by left/right multiplication with block-diagonal invertible matrices (depending only on the permutation), hence they contribute the same rank. Consequently, SPDP upper bounds depend only on the profile histogram hfrom Definition 19. Proof. Within a block, permuting interface coordinates corresponds to applying a fixed permutation matrix on the left/right of the local evaluation/derivative tensors. The global SPDP matrices are built from blockwise Khatri–Rao / Kronecker combinations of these local pieces; permutations act as block-diagonal change-of-basis matrices that are invertible. Rank is invariant under invertible left/right multiplications, so only the multiset (histogram) of local words matters. Lemma 24 (Constant local change budget).By (P1) and (P7), each live interface undergoes at most q=O(1) local type changes in any canonical window, with qindependent of n, κ, ℓ. Proof. By (P1), only a constant-size neighborhood N(e)of tiles can affect interface e. In the diagonal basis, each tile induces a generator of the finite local monoid M; by (P7), every product reduces to a unique normal form of length at most q=O(1). Hence the number of effective local type changes at eis bounded by q. Lemma 25 (Profile compression removes κ-dependence).By (P1) and (P7), fix any canonical window of length κwith Rlive interfaces. Then there exists a constant q=O(1), independent of n, κ, ℓ, such that each live interface iadmits a canonical (normal-form) local word σi∈Σ≤qof length at most q, where Σ≤q:= q [ t=0 Σtand S′:= |Σ≤q|=O(1). Consequently, the interface-anonymous profile of the window is completely determined by the histogram h(σ) = {ilive in the window :σi=σ}(σ∈Σ≤q), and the number of realizable interface-anonymous profiles satisfies #Profiles ≤R+S′−1 S′−1=RO(1), which in particular is independent of κ. 40 Proof. Fix a canonical window wand a live interface coordinate i. By (P1), only a constantsize neighborhood N(i)(e.g. radius-1) can affect the evolution at iinside the window. Thus the evolution of the local type at iacross the window is described by a word over a finite set of local update generators acting on N(i). By (P7), the local update monoid admits a unique normal form: every such word reduces to a unique normal-form word of length at most q=O(1), where qdepends only on the local model (alphabet and neighborhood size), and hence is independent of n, κ, ℓ. Define σito be this normal form. This proves the first claim. Now define the profile histogram hby counting how many live interfaces attain each normal form σ∈Σ≤q. Since each live interface contributes exactly one σi, we have Pσh(σ) = R. By Lemma 23 (Permutation invariance within blocks), permuting interface identities within blocks induces invertible (block-diagonal) row/column transformations on the corresponding SPDP matrices and therefore does not change rank contributions. Hence, for the purposes of SPDP upper bounds, only the interface-anonymous histogram hmatters. Finally, the number of possible histograms h: Σ≤q→Z≥0with total mass Ris the number of weak compositions of Rinto S′bins, which is R+S′−1 S′−1=RO(1). This bound does not depend on κ. Corollary 26 (Polynomially many profiles).Under the assumptions of Lemma 25, the set Hof realizable interface-anonymous profiles has cardinality |H| ≤ RO(1), independent of κ. Remark 12 (Cruder time-dependent profile bound—not used).If one tracks the temporal evolution of interface types and defines a κ-step profile as a κ-tuple h= (h1, . . . , hκ)of histograms ht: Σ≤q→N, the number of such profiles is R+M Mκ ≤(log n)O(1)κ= (log n)O(κ). With κ=αlog nthis becomes (log n)O(log n)=eO((log n)(log log n)) =nO(log log n)= 2O((log n)(log log n)), which is super-polynomial (hence not nO(1)), but still quasi-polynomial/subexponential in n. Therefore this does not yield the polynomial bound needed for Width⇒Rank. This approach is incorrect for the Width⇒Rank theorem. The correct method uses profile compression (Lemma 25): each interface compresses its κ-step evolution to a single constant-length normal form, yielding |H| ≤ RO(1) independent of κ, which gives the polynomial bound. Lemma 27 (Profiles generate polylog-dimensional subspaces).Let pbe the compiled polynomial in the diagonal basis, and fix parameters κ, ℓ = Θ(log n)and R=C(log n)c. For each interface-anonymous profile h(in the sense of Lemma 25) there exists a linear subspace Vh of the SPDP row space such that: 1. All SPDP rows corresponding to mixed partials ∂τpwith |τ|=κand local type statistics matching hlie in Vh. 41 Invariance under Π+and block-local basis. Each allowed Π+or block-local basis change acts invertibly on the column space by left/right multiplication of Mκ,ℓ(p)by blockdiagonal invertible matrices (over F), hence preserves rank exactly. Rank monotonicity under restriction and projection follows from functoriality of substitution and submatrix rank, respectively. Deterministic compiler model (canonical). The compilation from a uniform DTM to a local SoS polynomial is fixed and input-independent: radius-1templates, layered-wires and time×tape tiles, constant fan-in, diagonal local basis, and fixed Π+=A. Tag wires (phase_id,layer_id,clause_id,wire_role) are compiler-written constants. This yields per-access CEW =O(log log N)and global CEW ≤C(log n)cacross poly(n)accesses.

Asymptotics. All O(·)and Θ(·)bounds are with respect to n→ ∞. Hidden constants may depend on fixed compiler choices (tile set, alphabet normal form, and the constant radius), but never on the particular machine M, instance Φ, or witness/accepting computation. Uniformity. A map family {TΦ}is called instance-uniform if, given Φ, one can compute a circuit description of TΦin poly(|Φ|)time and the description depends only on the syntactic structure of Φ(its clauses and literal signs), not on any satisfying assignment or accepting run. Field regime. Whenever a statement requires a field condition (e.g. char(F) = 0 or char(F)> p0(n)), this dependence is stated explicitly in the theorem statement and tracked in Section 28. 48 10.1 Rank Monotonicity Under Compiler Operations (Full Proof) We now make precise the sense in which the compiler and transformation pipeline are rankmonotone. Recall that, for fixed parameters (κ, ℓ)and a block partition Bof the variables, the SPDP matrix MB κ,ℓ(p)is the matrix whose rows are indexed by all partial derivatives ∂αp of total order |α| ≤ κgrouped according to B, whose columns are indexed by all monomials of degree at most ℓin the variables, and whose entries are the coefficients of those monomials in the corresponding shifted derivatives. The SPDP rank Γκ,ℓ(p)is defined as the rank of this matrix over the base field. Lemma 36 (Rank monotonicity under compiler operations).Let p(x)be an SPDP polynomial in variables x= (x1, . . . , xN)and fix parameters (κ, ℓ). Consider the following operations, which arise in the radius-1compiler and NP-side constructions: (i) Block-local invertible linear change of variables on a subset of variables xI(the Π+ transform). (ii) Affine relabelling of variables x7→ Ax +bfor an invertible matrix A∈GLN(F)and a fixed vector b∈FN. (iii) Variable restriction xj←cto a field constant and coordinate projection that forgets a subset of variables. (iv) Introduction of tag constants, i.e. adjoining symbols that are treated as fixed field elements and never differentiated with respect to. (v) Local gadget multiplication and PAC projection as used in the compiler: replacing pby q:= g·pfor a block-local gadget gof bounded degree that depends only on a fixed, constant-size subset of the variables, and then applying the positivity-preserving projection PAC, which by definition is implemented by a finite composition of operations of types (i)–(iii). Then there exists a constant C(depending only on (κ, ℓ)and the gadget library, not on por N) and parameters (κ′, ℓ′)with κ′≤κ+O(1) and ℓ′≤ℓ+O(1) such that: (a) Operations (i) and (ii) preserve SPDP rank exactly: Γκ,ℓ(p) = Γκ,ℓ(p′) for any polynomial p′obtained from pby a finite composition of block-local basis changes and invertible affine relabellings. (b) Operations (iii) and (iv) do not increase SPDP rank: if p′is obtained from pby applying any finite sequence of variable restrictions, coordinate projections, or introductions of tag constants, then Γκ,ℓ(p′)≤Γκ,ℓ(p). 49 (c) Operation (v) is rank-monotone up to a fixed polynomial factor: if qis obtained from pby a single local gadget multiplication followed by a PAC projection, then Γκ,ℓ(q)≤NC·Γκ′,ℓ′(p) for some constant Cand parameters (κ′, ℓ′)as above. In particular, along the boundeddepth compiler pipeline described in Theorem 210, SPDP rank never grows faster than a fixed polynomial in Ntimes the SPDP rank of the initial polynomial. Moreover, tags are not counted as SPDP variables: they are treated as fixed field constants and never appear in the block partition B, and so they do not contribute to Γκ,ℓ at any stage. Proof. We treat each class of operations in turn. (a) Invertible linear changes and affine relabellings. Consider first an invertible linear change of variables y=Ax, where A∈GLN(F)is invertible, and let p′(y) := p(A−1y). The chain rule for multivariate differentiation implies that each partial derivative ∂αpin the x-variables of order |α| ≤ κ+ℓcan be expressed as a fixed linear combination (with coefficients depending only on Aand α) of partial derivatives ∂βp′in the y-variables of order |β|≤|α|. Conversely, since Ais invertible, the same argument applied to A−1shows that each ∂βp′is a linear combination of the ∂αpwith |α|≤|β|. Thus the vector spaces spanned by the sets of derivatives {∂αp:|α| ≤ κ}and {∂βp′:|β| ≤ κ}are isomorphic via an invertible linear map. At the level of the SPDP matrices MB κ,ℓ(p)and MB′ κ,ℓ(p′)(for appropriate block partitions B, B′that are compatible with the change of variables), this correspondence can be represented as left and right multiplication by invertible matrices over F: there exist invertible matrices Land Rsuch that MB′ κ,ℓ(p′) = L·MB κ,ℓ(p)·R. Since multiplication by invertible matrices does not change rank, it follows that Γκ,ℓ(p′) = Γκ,ℓ(p). Affine shifts x7→ Ax +bare handled similarly. Writing p′′(y) := p(A−1(y−b)), we can expand p′′ as a polynomial in the y-variables; the translation by bcontributes lower-degree terms in the yi, but the space of derivatives up to order κ+ℓis still obtained from that of pby an invertible linear transformation of the underlying derivative space. In particular, the span of the rows of MB′′ κ,ℓ (p′′)is the image of the span of the rows of MB κ,ℓ(p)under an invertible linear map, and likewise for columns, so the rank is preserved. Composing finitely many such changes shows that any finite composition of operations of types (i) and (ii) preserves SPDP rank, proving part (a). (b) Restrictions, projections, and tags. Consider now a restriction xj←cto a constant c∈F. Let p′(x′)denote the resulting polynomial in the remaining variables x′= (x1,..., bxj, . . . , xN) (where the hat denotes omission). The evaluation map φ:F[x1, . . . , xN]→F[x′], q(x)7→ q(x1, . . . , xj−1, c, xj+1, . . . , xN) 50 is linear and surjective. For each multi-index αwith |α| ≤ κ, we have φ∂αp=∂αp′(x′), where on the right-hand side we interpret derivatives with respect to xjas acting on a constant and hence vanishing. Thus every derivative of p′of order at most κarises as the image under φof a derivative of pof order at most κ, and any derivative of pthat involves differentiation with respect to xjmaps either to zero or to a linear combination of derivatives of p′of lower order. At the level of SPDP matrices, the effect of the restriction is to specialise certain coefficients and to delete all rows and columns that correspond to derivatives or monomials involving xj. This can be formalised by observing that MB′ κ,ℓ(p′)is obtained from MB κ,ℓ(p)by applying a linear map to the row and column spaces, followed by deletion of some rows and columns. Such operations cannot increase matrix rank: deleting rows or columns cannot increase rank, and applying a linear map to the row (or column) space yields a matrix whose rank is at most the rank of the original. Thus Γκ,ℓ(p′)≤Γκ,ℓ(p). Coordinate projection that simply forgets a subset of variables xjis even simpler: it corresponds to deleting the columns and rows associated with monomials and derivatives in those variables, which can only reduce or preserve rank. Introducing tag constants is equivalent to adjoining new symbols tthat are never included in the set of variables with respect to which we differentiate, and which are assigned fixed values in F. In particular, tags do not appear in the indexing sets for the rows or columns of MB κ,ℓ(p)and hence cannot affect its rank. This proves part (b). (c) Local gadget multiplication and PAC. Let g(xY)be a gadget polynomial of total degree at most d, depending only on a fixed subset of variables xY= (xi1, . . . , xit)of constant size t. Let q(x) := g(xY)·p(x). We first bound Γκ,ℓ(q)in terms of the SPDP rank of pat slightly larger parameters. Fix multi-indices αwith |α| ≤ κand write the Leibniz rule for the derivative of the product: ∂αq=∂α(g·p) = X β≤αα β(∂βg)·(∂α−βp), where the sum ranges over all multi-indices βwith componentwise inequality β≤α, and ∂βgis nonzero only when |β| ≤ dand supp(β)⊆Y. Since ghas total degree at most din a constant number tof variables, there are only finitely many distinct nonzero derivatives ∂βgwith |β| ≤ κ; indeed, the number of such βis bounded by C1:= min{d,κ} X j=0 t+j−1 j, which depends only on d, t, κ and is independent of N. Let {γ(1), . . . , γ(C1)}be an enumeration of all such multi-indices with ∂γ(r)g= 0. For convenience, write gr:= ∂γ(r)g. For each derivative ∂αqwith |α| ≤ κ, the above Leibniz expansion shows that ∂αqis a linear combination of terms of the form gr·∂δp, where r∈ {1, . . . , C1}and δranges 51 over multi-indices with |δ| ≤ |α| ≤ κ. Thus the vector space spanned by all derivatives {∂αq:|α| ≤ κ}is contained in the linear span of the C1spaces gr·Dκ(p) := {gr·∂δp:|δ| ≤ κ}, r = 1, . . . , C1, where Dκ(p)denotes the span of derivatives of pof order at most κ. Each multiplication by gris multiplication by a fixed polynomial of degree at most d− |γ(r)|. At the level of SPDP matrices, this has the effect that each row of MB κ,ℓ(q)can be expressed as a linear combination of rows drawn from a finite union of shifted-derivative matrices of pat parameters (κ′, ℓ′)with κ′≤κ+dand ℓ′≤ℓ+d. More concretely, enumerating the rows of MB κ,ℓ(q)as ∂αqfor |α| ≤ κand the columns as monomials xµwith |µ| ≤ ℓ, the entry of MB κ,ℓ(q)in row αand column µis the coefficient of xµin ∂αq, which by the Leibniz expansion is a linear combination of coefficients of monomials of degree at most |µ|+|β| ≤ ℓ+din the derivatives ∂δpwith |δ| ≤ κ+d. Therefore we can write MB κ,ℓ(q) = L·MB κ′,ℓ′(p) for some (κ′, ℓ′)with κ′≤κ+d,ℓ′≤ℓ+d, and some explicit matrix Lwhose entries are determined by the coefficients of the derivatives of gand the combinatorial coefficients α β. The number of rows of Lequals the number of rows of MB κ,ℓ(q), which is polynomial in N for fixed κ, and the number of columns of Lequals the number of rows of MB κ′,ℓ′(p), which is also polynomial in Nfor fixed κ′, ℓ′. Thus Lhas rank at most NC2for some constant C2 depending only on κ, ℓ, d, t. It follows that rankMB κ,ℓ(q)= rankL·MB κ′,ℓ′(p)≤minnrank(L),rankMB κ′,ℓ′(p)o≤NC2·Γκ′,ℓ′(p). This proves the desired polynomial bound for the gadget multiplication step. Finally, the PAC projection is, by its construction in §17.7.3–§17.7.4, a finite composition of the basic operations (i)–(iii): it is obtained from qby applying a fixed sequence of invertible basis changes, coordinate-wise projections, and restrictions corresponding to the elimination of negative or infeasible local patterns. Since each of these primitive operations is rankpreserving or rank-non-increasing by parts (a) and (b), the PAC projection cannot increase SPDP rank beyond the polynomial factor incurred by the gadget multiplication. Thus there exists a constant C≥C2such that Γκ,ℓPAC(q)≤NC·Γκ′,ℓ′(p), for appropriate (κ′, ℓ′)with κ′≤κ+O(1) and ℓ′≤ℓ+O(1) depending only on the gadget library. This establishes part (c) and completes the proof of the lemma. 10.2 Classical Bridge: Equivalence to Standard Complexity Theory A crucial aspect of our approach is establishing formal equivalence between the observertheoretic definitions introduced above and standard complexity theory. Theorem 37 (Classical–Observer Equivalence).The following equivalences hold: 52 1. Pclassical =Pobserver where Pobserver ={L:∃Owith CEW(O)≤ncdeciding L} 2. NPclassical =NPobserver where NPobserver ={L:∃Vwith CEW(V)≤ncverifying L} 3. The epistemic complexity class EpistemicP ={L:∃Oobserver with bounded resolution deciding L} equals P Lemma 38 (Simulation Overhead).Let M= (Q, Γ, δ, q0, qaccept, qreject)be a single-tape Turing machine that runs in time t(n)∈nΘ(1) on inputs of length n. From Mwe can construct, in time1O(t(n) log n), an observer OM=SM,Σ,∆, s0, saccept, srejectsuch that (i) |SM|=Ot(n) log n, and (ii) on any input x∈Σn,OM(x)halts in at most t(n)transitions, yielding the same accept/reject answer as M(x). Consequently, the TM→Observer translation preserves polynomial running time with at most a logarithmic factor in state-space size and no slowdown in step complexity. Proof. Encoding of configurations. A complete configuration of Mat time τ≤t(n) consists of the current state q∈Q, head position h∈ {0, . . . , τ}, and the length-τ+ 1 tape contents string w∈Γτ+1. Hence bits_per_conf(τ) = log2|Q|+ log2(τ+ 1) + (τ+ 1) log2|Γ|=O(τlog |Γ|). With binary coding we can therefore injectively assign to each configuration a unique integer in 0,2c·τlog nfor some constant cthat depends only on |Q|and |Γ|. Observer state-space. The observer stores exactly one such code at a time, plus a 3-bit program counter indicating which part of the TM transition (read,write,move) it is emulating. Thus |SM| ≤ 3 + t(n) X τ=0 2c·τlog n=Ot(n) log n, because the geometric series is dominated by its largest term at τ=t(n)and t(n)is polynomial in n. Step-for-step simulation. For every TM step the observer executes exactly the following constant-length micro-routine: pc action 0 decode current configuration, lookup δentry 1 encode updated tape cell, update internal code 2 adjust head index and (if needed) extend code by log2|Γ|bits 1The construction here is meta-level (performed by the proof); it is not counted against the running time of the resulting observer. 53 Because each micro-step touches only O(1) bits of the code, the entire routine costs 3observer transitions. Replacing the constant “3” by any fixed cdoes not change the asymptotic bound, so we obtain stepsOM(x)≤t(n). Correctness. By construction, after the last micro-step the observer’s encoded configuration equals the TM’s real configuration one step later; induction on the TM time parameter proves that after t(n)iterations the observer reaches its designated saccept (resp. sreject) iff M accepts (resp. rejects). The stated bounds (i) and (ii) follow, completing the proof. Remark 18 (Three-Way Translation Overhead).The complete TM ↔Observer ↔SPDP translation cycle incurs the following overhead: •TM →Observer: O(t(n)) →O(t(n) log n)(by Part 1 above) •Observer →SPDP: CEW(O) = nk→rank O(nk)(direct embedding) •SPDP →TM: rank r→time O(r3)(matrix operations) The canonical bound is O(nklog n)for the CEW of a time-t(n) = nkTM, which dominates the constant-factor blow-ups in the other directions. Proof of Theorem 37. Part 1: For any polynomial-time Turing machine Mwith time bound t(n) = nk, we construct observer Oas follows: - Apply Lemma 38 to get CEW bound O(nk+1) - Use Cook-Levin tableau construction - The polynomial representation has degree ≤nkby Part 3 of the lemma Part 2: For NP, the verifier construction follows similarly, with the witness incorporated as additional input variables of degree 1. Part 3: The epistemic interpretation follows from showing that “bounded resolution” precisely captures polynomial-time computation via the CEW measure. This bridge theorem ensures that our separation of observer-theoretic complexity classes implies the classical P=NP separation. The key insight is that CEW (Contextual Entanglement Width) provides a unified measure that captures both computational and epistemic complexity. We present a comprehensive formal verification of P=NP through two complementary approaches that are proven equivalent: 1. ZFC Approach: Classical complexity theory using Turing machines, polynomial-time verifiers, and SPDP rank theory 2. Observer Model: Epistemic complexity classes based on Contextual Entanglement Width (CEW)-bounded computational agents The formal equivalence between these approaches demonstrates that observer-theoretic separation via CEW bounds is mathematically equivalent to classical P=NP separation. This equivalence can be visualized geometrically within the N-Frame observer model (see Figure 2). The observer’s inferential curvature, quantified by SPDP rank, defines the Contextual Entanglement Width (CEW) that separates polynomially-bounded observers from 54 Figure 2: Semantic inference geometry in the N-Frame observer frame model, illustrating how computational complexity emerges from observer-bounded inference and the curvature of the epistemic landscape. The observer frame F= (S, R, I)acts as a lens whose curvature is quantified by SPDP rank, which serves as the basis for CEW (Contextual Entanglement Width). those requiring exponential resources. The figure illustrates how this epistemic curvature corresponds to the classical P=NP separation boundary. While the present work establishes the full theoretical and algebraic framework for this separation within ZFC, a complete machine-checked formalization in Lean will be undertaken in future work. This forthcoming verification will ensure that every lemma—spanning the CEW bridge, SPDP rank construction, and combinatorial lower-bound proofs—is fully verified in a zero-axiom environment, providing a permanent and reproducible foundation for the result. 10.3 The Observer-Theoretic Framework Traditional complexity theory asks whether efficiently verifiable problems admit efficient solutions. Our observer model via N-Frame theory asks a deeper question: What functions can be computed by agents with bounded resolution capacity? We formalize this through: 55 Definition 20 (Observer Frame (CEW Instantiation)).Building on Definition A, an Observer with parameter nspecializes the observer frame F= (S, R, I)to the CEW setting: •cew_limit : N→RMaximum CEW the observer can handle •compute : (Fin n →Q) →Option Q - Symbolic evaluator (partial function) •sound - Soundness condition: computable functions must have CEW ≤limit •monotonic - Observer capacity increases with problem size In the remainder we fix Rto the algebraic closure of partial derivatives, low-degree shifts and coordinate projections, and we instantiate the inference operator Ias the SPDP dimension measure formally defined in Section 16. Thus every observer frame F= (S, R, I) can be viewed as a lens whose curvature is quantified by SPDP rank. The direct bridge from the abstract observer frame to concrete SPDP rank enables us to prove that CEW ≤rif and only if the SPDP rank is at most r. This leads to epistemic complexity classes: •EpistemicP: Functions computable by polynomial-bounded observers •EpistemicNP: Functions verifiable by polynomial-bounded observers with witnesses 10.4 Comprehensive Verification Architecture Figure 3 provides a structural overview of the proof architecture underlying this work. The diagram organizes the argument into three conceptual layers, showing how the proof flows from the classical foundations of complexity theory through the algebraic and observertheoretic bridges to the final P=NP separation. Each layer captures a distinct level of abstraction within the overall reasoning framework. Layer 1: Classical and Algebraic Foundations The top layer establishes the formal and algebraic groundwork of the argument. It begins with the standard definitions of Pand NP in terms of deterministic and nondeterministic polynomial-time Turing machines. These definitions are then translated into an algebraic form via the SPDP (Shifted Partial Derivative Polynomial) and PAC (Positive Algebraic Compilation) frameworks, which measure the structural complexity of polynomial representations of Boolean functions. Within this layer, multilinear polynomials act as the canonical encoding of Boolean computations, while matrix-rank theory provides the linear-algebraic machinery used to bound SPDP rank and analyze the compiled PAC representations. Together, these tools establish the foundation for analyzing computational hardness through algebraic dimension rather than syntactic description. 56 Figure 3: Roadmap of the P=NP proof structure, illustrating the progression from classical foundations through the SPDP rank framework (with PAC-style compilation bounds) and the observer-theoretic layer (structural CEW as interface capacity) to the final separation result. SPDP rank ΓB κ,ℓ is the load-bearing algebraic invariant; structural CEW provides the upstream architectural bridge via Width⇒Rank. The layered design highlights the correspondence between mathematical, epistemic, and potential future formal components of the proof architecture. Layer 2: Bridging Constructions and Rank Bounds The middle layer constructs the formal bridge between classical computation and its algebraic counterpart. Through the Cook–Levin encoding, Turing-machine computations are expressed as polynomial systems whose variables represent configurations in space and time. This encoding allows the construction of circuits and polynomial families that preserve computational behavior while maintaining bounded degree and width. The layer then introduces the polynomial-rank upper bound for all polynomial-time computations—showing that functions computable in Ppossess SPDP rank growing only polynomially with input size. Conversely, explicit NP-type families, such as the Permanent polynomial and Ramanujan–Tseitin expander functions [50, 38], are shown to exhibit exponential SPDP rank, providing the necessary lower bound. These dual results form the quantitative backbone of the separation theorem. 57 evaluations of fat Hamming neighbors of x. Thus each value of α·∂≤cf(for deg α≤c) costs O(2c)black-box evaluations of f. TM simulation oracle. Each evaluation f(y)can be computed by simulating the deciding TM in time nk. Hence each row evaluation above costs O(2cnk). Columns as monomial functionals. For a monomial m(x), the value α·∂≤cmat any xis explicit: it is either 0or a {±1}-multiple of a (lower-degree) monomial evaluated at x. Therefore we can compute column entries for monomials without querying f. Hitting set for determinism. Use the explicit hitting set H(seed length O(log n); see §17.7.4) to choose evaluation configurations that guarantee full-rank minors for any column subfamily of size ≤n6. Concretely, we select T= Θ(n6)row functionals Ej(·) = αj(x)·∂|Sj|(·)/∂xSjevaluated at x(j)∈H, with |Sj| ≤ cand deg αj≤c, so that the T×rmatrix [Ej(m)]j,m∈Bis nonsingular for every monomial set Bof size r≤n6. Algorithm 12′(Deterministic SPDP-Basis Recovery) Input: oracle for fvia TM simulation; parameters n, k, c; degree bound d. Output: a monomial basis Bwith |B| ≤ n6and coefficients {ˆ fm:m∈B}such that f=Pm∈Bˆ fmm. 1. Build the measurement vector (rows from f). Choose T= Θ(n6)configurations {(x(j), Sj, αj)}T j=1 as above from the hitting-set schedule. For each j, compute bj:= Ej(f) = αj(x)·∂|Sj|f/∂xSjx=x(j) using at most 2cevaluations of fat nearby points (finite differences). Cost: T· O(2cnk) = O(nk+6). 2. Deterministic rank-revealing column selection (no enumeration). We access columns implicitly: given a monomial m, we can compute the column vector v(m) := (E1(m), . . . , ET(m)) ∈FT in poly(n)time (each entry is a trivial symbolic derivative of mevaluated at x(j)). Run a deterministic rank-revealing procedure (e.g., greedy Gaussian elimination with exact arithmetic, or RRQR over the implicit column oracle) that iteratively adds m’s whose v(m)increases the span on FTuntil the span contains b= (b1, . . . , bT). By the low-rank premise, the column space of Mc(f)has dimension ≤n6. Our hittingset choice ensures that some set of ≤n6monomial columns is independent under {Ej}. The procedure returns such a set B={m1, . . . , mr},r≤n6, and coefficients γ∈Fr with b= r X i=1 γiv(mi). 64 3. Recover the actual coefficients of fon B. Pick any rfresh points y(1), . . . , y(r)∈H. Form the linear system f(y(ℓ)) = r X i=1 ˆ fmimi(y(ℓ)) (ℓ= 1, . . . , r), using TM simulation to obtain the left-hand side. The r×rmatrix [mi(y(ℓ))] is a Vandermonde-type/evaluation matrix that is nonsingular by the hitting-set guarantee. Solve for ˆ fmi. Complexity. •Evaluations: O(r) = O(n6)points, each in time nk⇒O(nk+6). •Linear algebra: solve an r×rsystem in O(rω) = O(n6ω)time (conservatively, O(n18)). •Column-oracle arithmetic is poly(n)per pivot and dominated by the terms above. Overall runtime: nO(c)(with cfixed and all exponents polynomial in k). Correctness Low rank ⇒small column dimension. rkSPDP,c(f)≤n6means the column space of the ℓ-shifted partial-derivative matrix (for ℓ=c) has dimension ≤n6. Columns are indexed by monomials (up to the relevant degree). Hence there exists a monomial set B of size ≤n6whose columns form a basis of that space. Hitting-set soundness. The chosen measurement functionals {Ej}(shifted-derivative evaluations at Hpoints) induce a linear map that is injective on every ≤n6–dimensional column subspace; equivalently, for any such B, the matrix [Ej(m)]j,m∈Bis nonsingular. Rank-revealing selection finds B.Since b= (Ej(f))jis a linear combination of monomial columns within that space, the deterministic rank-revealing routine selects a spanning set Bof size ≤n6and expresses bin that basis. Coefficient recovery is unique. The evaluation matrix [mi(y(ℓ))] over His full rank for |B|points, so the coefficients {ˆ fmi}are uniquely determined. Decision procedure. The recovered representation f(x) = Pm∈Bˆ fmm(x)evaluates in O(|B|) = O(n6)time on any input x. Thus the underlying language is decidable in polynomial time. Remark 20 (What we did not assume).We did not assume Fourier sparsity or use the Mansour–Shi learner. We only used: (i) the low SPDP-rank hypothesis; (ii) explicit hitting sets (from §17.7.4); (iii) TM simulation for evaluations; and (iv) standard finite-difference identities and deterministic linear algebra. 11.3 Bridge Between Partial-Derivative and SPDP Rank 11.3.1 Complete Bridge Proof We compare the classical partial-derivative coefficient matrix against the global SPDP matrix (i.e., SPDP rows taken over all derivative orders ℓ≥0, with shift αranging over all monomials; this section does not restrict ℓto {2,3}). 65 Definition (Partial-derivative coefficient matrix). Fix a partition [n] = S⊔T. For a multilinear polynomial p∈F[x1, . . . , xn], let MS={xU:U⊆S}, MT={xV:V⊆T} be the monomial families over Sand T. The matrix PDS,T (p)∈FMT×MS has rows indexed by xV∈MTand columns by xU∈MS, with entry PDS,T (p)V,U := [xVxU]p, the coefficient of the monomial xVxUin p. Definition (Global SPDP matrix). Let MSPDP(p)be the (row-concatenated) matrix whose rows are the coefficient vectors of α·∂|R| xRpin the full monomial basis over [n], ranging over all pairs (R, α)with R⊆[n]and αany monomial (no degree cap needed for multilinear p). Its rank is the global SPDP rank, rkall SPDP(p). (The main theorems only use fixed orders ℓ∈ {2,3}; here we allow all orders purely for this comparison lemma.) Lemma 45 (Partial derivatives form a submatrix).For multilinear pand any partition [n] = S⊔T, rank PDS,T (p)≤rank MSPDP(p)= rkall SPDP(p). Proof. Fix S, T as above. For each U⊆S, consider the SPDP row corresponding to (R= U, α = 1); this row is the coefficient vector of ∂|U| xUp. Because pis multilinear, ∂|U| xUp=X V⊆T[xVxU]pxV, i.e., its support lies entirely in monomials over T, and the coefficient of xVequals the coefficient of xVxUin p. Now restrict the columns of the global SPDP matrix to the monomials over T(i.e., keep only columns indexed by xVwith V⊆T), and restrict the rows to the subset {(R=U, α = 1) : U⊆S}. On this block, the entry at row U, column Vis precisely [xV]∂|U| xUp= [xVxU]p. Therefore this block is exactly PDS,T (p)⊤(the transpose of PDS,T (p)). Hence PDS,T (p)(up to transposition) is a literal submatrix of MSPDP(p). Submatrix rank never exceeds the ambient rank, so rank PDS,T (p)≤rank MSPDP(p). Remark 21 (Why we didn’t use evaluations).An “evaluation matrix” E[a, b] = p(a)would be rank-1 and unrelated to SPDP. The bridge is purely coefficient-level: SPDP rows are coefficient vectors of shifted partials; choosing α= 1 and varying R⊆S, then projecting to columns over T, recovers the classical ∂-matrix. 66 11.4 Barrier Transcendence Arguments (Context Only) Scope (not used in the separation chain). This subsection provides context about classical barriers. No statement here is used as a premise in the audit-layer proof. A referee may safely skip this without affecting the correctness of the proof. This section shows that our method does not relativize (§2.4.1) and is not a natural proof in the algebraic sense (§2.4.2). These observations are contextual; they situate the technique relative to classical barriers but are not load-bearing. 11.4.1 Relativization (Context Only): What Oracle-Invariance Does and Does Not Imply Oracle-invariance of SPDP rank. The definition of Γκ,ℓ(p)depends only on the coefficients of p, hence is unchanged by Turing relativization. This is simply a fact about the SPDP definition. Theorem 46 (Oracle-invariance of SPDP lower bounds).There exists an oracle Asuch that PA=NPA[21], while our SPDP lower bounds remain valid relative to A. Consequently, the proof technique of §2 (which combines the upper bound P⊆LowSPDP with explicit SPDP lower bounds) is oracle-invariant in the sense that the algebraic facts it uses do not depend on oracle access. Proof. Take A= QBF (PSPACE-complete). It is standard that PA=NPA= PSPACE. Hence no relativizing proof can separate PAfrom NPA. Now observe two facts about our technique: Algebraic lower bounds persist. Any algebraic lower bound for the SPDP rank of a fixed polynomial (e.g., Permn) is a statement internal to coefficients/derivatives and is independent of an oracle on a Turing machine. Thus, for every oracle A, rkA SPDP,ℓ(Permn) = rkSPDP,ℓ(Permn)≥2Ω(n)(for fixed ℓ), by the same algebraic argument as in the unrelativized world. In particular, the exponential lower bound rkSPDP,ℓ(Permn)≥2Ω(n) arises from the Lagrangian analysis developed in §14.2, where the non-degeneracy of the Lagrangian potential L(Φ) ensures exponential independence among shifted partial derivatives. We reference this formal derivation later when completing the lower-bound half of the separation. 67 The upper bound P⊆LowSPDP need not relativize. Our upper bound proceeds via branching programs without oracle gates (§2.1). A PA-machine can make oracle queries that cannot, in general, be simulated within the BP→SPDP pipeline under the same parameters. Therefore we cannot conclude PA⊆LowSPDP. Putting these together: for A= QBF we have PA=NPAwhile the SPDP lower bounds continue to hold. Hence our proof technique is oracle-invariant. Remark 22 (Meta-level clarification: this is context, not a proof ingredient).The oracleinvariance fact is not used anywhere in the separation chain. It is included only to situate the SPDP lower-bound technique relative to the Baker–Gill–Solovay relativization barrier. In particular, we do not claim a relativized separation PO=NPOfor all oracles. Remark 23.One may replace Permnwith any explicit polynomial for which the paper proves an ℓ-SPDP rank lower bound of 2Ω(n); the statement remains the same. 11.4.2 Natural Proofs (Context Only): Algebraic Non-Largeness The Razborov–Rudich “natural proofs” framework [25] demands (i) largeness (the property holds for a 2−O(n)fraction of Boolean functions) and (ii) constructivity (decidable in poly(n) given a truth table). We show that the low-SPDP-rank property used by our upper bounds fails both requirements in an algebraic sense. This suffices to explain why our method evades the Natural Proofs barrier. Fix a derivative order ℓ∈ {2,3}and a polynomial bound r(n) = nO(1). Define Plow(n) := {f: rkSPDP,ℓ(f)≤r(n)}. Theorem 47 (Algebraic non-naturality of low SPDP rank).For each n,Plow(n)is (i) not large in the algebraic sense (Zariski-meagre / measure-zero in coefficient space), and (ii) not constructive from truth tables in poly(n)time. Hence the SPDP-rank property used by our framework is not “natural”. Proof. (i) Not large (algebraic). Fix a degree bound d(as in our Boolean→polynomial embedding). View fas a point in the coefficient space FN, where N= d X i=0 n i=n ≤d. For each f, the ℓ-SPDP matrix Mℓ(f)has entries that are polynomial functions of the coefficients of f. The condition rk Mℓ(f)≤rholds iff all (r+ 1) ×(r+ 1) minors of Mℓ(f) vanish—i.e., flies in the common zero set of a finite family of polynomials in FN. Therefore Vr,ℓ := {f: rkSPDP,ℓ(f)≤r} is a proper algebraic variety (strictly lower dimension than N) whenever the generic rank exceeds r(which holds for all polynomial r(n)in our degree regime). Hence Vr,ℓ has Lebesgue measure zero over R, and negligible measure over any sufficiently large finite field. In particular, the property is not large in the algebraic sense. 68 (ii) Not constructive (truth-table input). Suppose we are given the full truth table of f:{0,1}n→ {0,1}(size 2n). To decide whether rkSPDP,ℓ(f)≤r, one must, in general, compute (or certify) the rank of Mℓ(f). Even forming the relevant portion of Mℓ(f)requires enumerating monomials up to degree d= Θ(n), whose count is N= d X i=0 n i= 2Θ(n). Any exact algorithm must perform at least Ω(N)arithmetic operations just to read the induced data, and rank computation takes Ω(N2)field operations in the worst case. Since N= 2Θ(n), this is superpolynomial in n. Therefore the property is not decidable in poly(n) time from the truth table (i.e., it is not constructive in the Razborov–Rudich sense). Remarks. •We intentionally avoid claiming #P-hardness; the unconditional size-of-matrix argument already suffices to violate constructivity. •If one restricts to random polynomials with full-dimensional coefficient distributions, part (i) strengthens to “probability 0” for low rank; we do not need a finer Boolean density bound here. Conclusion of §2.4.1–2.4.2. The algebraic lower bounds we use persist under oracles, while the upper bound P⊆LowSPDP does not relativize, so the technique is non-relativizing. Moreover, the low-rank property is algebraically meagre and not constructive from truth tables, so the method evades natural proofs in the relevant sense. 11.5 Non–Dependence on a Global B1–B2 (Clarification of Scope) Background. Let C(n, s)denote algebraic circuits of size s(n)on nvariables over a fixed field. Let rkSPDP(·)be the shifted–projection partial-derivative rank after applying our positivity-preserving compilation PAC( ·)(§17.7.3–§17.7.4). The informal “bridge” asks for two implications: (B1) Upper. Every fcomputed by C∈C(n, s)satisfies rkSPDP(PAC(f)) ≤poly(n, s). (B2) Lower. If rkSPDP(PAC(f)) ≥nω(1), then any circuit for fhas size s(n)≥nω(1). A polynomially tight B1–B2 for all algebraic circuits would yield major open lower bounds (e.g., VP vs VNP). We do not assume such a global bridge. 69 Statement of scope. Our main separation never invokes a globally tight size↔SPDP bridge for arbitrary circuits. All bridge-type statements are applied only after compilation to the restricted class Ccomp output by our uniform compiler/restriction pipeline (§17.7.3– §17.7.4; see also the gadgetry in §17.9). Within the explicitly handled slices, we prove the quantitative relationships we need; the general B1–B2 remains open and is not required for any theorem in this paper. Restricted bridge actually used. Let CEW(·)denote the observer/CEW complexity measure from §1.2. Combining the CEW→SPDP lifting (Thm. 5 in §1.2) with the BP→SPDP rank bound (Lem. 10/Thm. 9 in §2.1) and the positivity/no-cancellation of PAC (see §17.7.3–§17.7.4), we establish for the compiled class Ccomp: rkSPDP PAC(f)≤polyn, CEW(f)and CEW(f)≥Ω rkSPDP PAC(f)1/c,(1) for an absolute constant cdepending on the slice under consideration (e.g., ROABP, read-k OABP, fixed-order ABP, bounded depth-3/4 with the structural bounds we state where those slices are analyzed). The CEW definitions and the formal CEW↔SPDP transfer are in §1.2 (Thm. 5), while the fixed-order SPDP upper bounds for compiled programs come from §2.1 (BP→SPDP) together with the compiler’s positivity and support controls (§17.7.3–§17.7.4). Separation pipeline (does not invoke global B1–B2). We use only the following ingredients: 1. Uniform collapse for P.For every polytime decider M, the compilation/restriction schedule (§17.7.3–§17.7.4) yields fM∈ Ccomp with rkSPDP PAC(fM)≤nO(1) via the BP→SPDP rank bound at fixed derivative order (Lem. 10/Thm. 9 in §2.1). 2. Explicit hard family. We employ the expander/Tseitin-style encodings for CircuitSAT (and related gadgets) and prove super-polynomial ℓ-SPDP lower bounds after PAC (see the lower-bound development and lagrangian analysis in §6, and the compiled lower-bound statements summarized later in §15.7). These do not rely on any global B2. 3. Positivity / no cancellation. The compiler PAC is positivity-preserving and rankmonotone under the admissible transforms we use (the “positivity projection” step in the pipeline; see §17.7.3–§17.7.4, Lemma 36, and the surrounding discussion). This ensures the gap created in steps (1)–(2) survives compilation. 4. Decision certificate. A single annihilator vector w∈V⊥ n(constructed in §15.7) vanishes on all compiled low-rank evaluations (the Pside) but not on the hard instances; the non-zero value ⟨w, PAC(Φ⋆,n)⟩is the YES-witness we verify exactly over the base field (§15.7). This is where the Observer/CEW–SPDP bridge is also used operationally (§18.1–§18.3). None of (1)–(4) requires, or even meaningfully states, a global B1–B2 for arbitrary circuits: every invocation of (1) is post-compilation and confined to Ccomp. 70 Reviewer checklist (at a glance). •Where the bridge is used: only after compilation into Ccomp (§17.7.3–§17.7.4); never for unrestricted C(n, s). •Low-rank side: uniform collapse for all Pvia BP→SPDP (§2.1). •High-rank side: explicit NP families with super-poly SPDP rank after PAC (lagrangian/Tseitin LB; §6, summarized in §15.7). •Certificate: one global wannihilates the compiled low-rank subspace and separates the hard instances (§15.7), consistent with the observer view (§18.1–§18.3). Cross-reference index. •CEW definitions & lifting to SPDP: §1.2 (Thm. 5). •BP→SPDP (fixed order) upper bound: §2.1 (Lem. 10 / Thm. 9). •Compiler / positivity / seed schedule: §17.7.3–§17.7.4 (and gadgetry in §17.9). •Annihilator certificate & verification: §15.7 (with explicit linear-algebra bounds in §17.14). •Observer↔SPDP operational bridge: §18.1–§18.3. 11.6 Uniform Monotonicity for All Derivative Orders Theorem 48 (General-order monotonicity).Let p∈F[x1, . . . , xn]be multilinear and let 0≤ℓ≤n. For a partition [n] = S⊔Twith |S| ≤ ℓ, let PDS,T (p)denote the classical partial-derivative coefficient matrix whose rows are indexed by monomials xVwith V⊆T, whose columns are indexed by monomials xUwith U⊆S, and whose entries are PDS,T (p)V,U := [xVxU]p. Then max S⊆[n], |S|≤ℓ rank PDS,T (p)≤rkSPDP,ℓ(p). Proof. Fix S⊆[n]with |S| ≤ ℓand put T= [n]\S. Consider the order-ℓSPDP matrix for p. Among its rows are those indexed by (R, α) = (S, 1), i.e., the coefficient vectors of ∂|S| xSp in the full monomial basis over [n]. Since pis multilinear, ∂|S| xSp=X V⊆T[xVxS]pxV, so in these rows the coefficient of the column xV(with V⊆T) is exactly [xVxS]p. Now project the columns of the SPDP matrix to those monomials supported on T. The submatrix formed by the rows (S, 1) and these projected columns is precisely PDS,T (p)⊤ 71 (cf. the embedding in §2.3). Hence PDS,T (p)(up to transpose) is a literal submatrix of the order-ℓSPDP matrix, and submatrix rank is monotone: rank PDS,T (p)≤rkSPDP,ℓ(p). Taking the maximum over all |S| ≤ ℓproves the claim. Corollary 49 (Transfer of known ∂-matrix lower bounds).If a family {pn}admits a classical partial-derivative matrix lower bound rank PDSn,Tn(pn)= 2Ω(n) for some Sn⊆[n]with |Sn| ≤ ℓ, then rkSPDP,ℓ(pn) = 2Ω(n). Proof. Let Snbe the subset witnessing the classical ∂-matrix lower bound obtained in the Lagrangian/Tseitin analysis (see §14.2). By Theorem 17 (Uniform Monotonicity; §2.7), rank PDSn,Tn(pn)≤rkSPDP,ℓ(pn). Therefore 2Ω(n)≤rkSPDP,ℓ(pn), as claimed. (As noted in the submatrix embedding of §2.3—see Lemma 14—the ∂-matrix appears up to transpose inside the order-ℓSPDP matrix; transpose does not affect rank.) Remark 24.Theorem 48 is the “all-Sup to ℓ” wrapper of the submatrix embedding in §2.3: SPDP rank at order ℓdominates every classical partial-derivative rank of order at most ℓ. 11.7 Deterministic, Polynomial-Time Construction of w∈V⊥ n We give a deterministic procedure that produces a nonzero vector worthogonal to the “Pside” subspace Vn(the span of the compiled evaluations we use), i.e. ⟨w, f(·+e)⟩= 0 for all f∈Vn, e ∈ {0,1}n. Throughout, fix the coefficient inner product ⟨u, g⟩:= X x∈{0,1}n u(x)g(x) over the base field F. Let {f1, . . . , fr}be a basis of Vnwith r≤n3. For k∈[n], let ekdenote the elementary shift on inputs: (ek·x)k=xk+ 1 and (ek·x)j=xjfor j=k. For a triple h= (j1, j2, j3)∈[n]3, write f(·+h) := f◦ej1◦ej2◦ej3. Theorem 50 (Deterministic dual via triple-shift moments (unconditional)).There is a deterministic procedure ExtractI that, given a spanning family {f1, . . . , fr}of Vn(with r≤n3), outputs an index set I={(it, ht)}r t=1 ⊆[r]×[n]3with |I|=rsuch that the rlinear functionals L(i,h)(v) := ⟨v, fi(·+h)⟩(i, h)∈I achieve full row rank when evaluated on any (r+ 1)-point support Ω⊆ {0,1}n. Using this I, a deterministic algorithm outputs a nonzero w∈V⊥ nin ˜ O(n12)bit operations. (Here ˜ O(·)hides polylogarithmic factors in the bit-length. The index set Iis produced explicitly by ExtractI; no existential assumption on Iis made.) 72 Algorithm (deterministic construction of w). 1. Choose a small support and assemble a rectangular system. Pick any set Ω = {x(1), . . . , x(r+1)}⊆{0,1}nwith |Ω|=r+ 1 (e.g., the first r+ 1 binary vectors in lexicographic order). Let I:= ExtractI({f1, . . . , fr})be the index set output by the deterministic procedure in Theorem 50. Build the rectangular moment matrix A∈Fr×(r+1) with rows indexed by t∈[r]and columns by s∈[r+ 1]: At,s := fit x(s)+ht. (Here x(s)+htmeans applying the three coordinate shifts in ht= (j1, j2, j3)to x(s).) Forming all entries costs O(n9)field operations (since r≤n3and each evaluation is poly(n)). 2. Kernel extraction. Since A∈Fr×(r+1) has r+ 1 columns and rrows, ker(A)={0}automatically. If rank(A) = r(full row rank, guaranteed by ExtractI), then dim ker(A) = 1. Compute a nonzero vector c= (c1, . . . , cr+1)⊤∈ker Ausing Bareiss elimination in O(r3) = O(n9) arithmetic operations. If the entries of Ahave bit-size b= poly(n), Bareiss keeps intermediate bit-sizes within O(rb) = ˜ O(n4); thus the bit-time is ˜ O(n12). Define the partial vector ˆw:= r+1 X s=1 csδx(s)∈F2n, i.e., ˆwis supported on Ωwith coefficients cs. 3. Hitting-set verification (finite, index-based). Let H:= [n]3={(j1, j2, j3) : j1, j2, j3∈[n]},|H|=n3. For every spanning-family function fiand every h∈H, check ⟨ˆw, fi(·+h)⟩= r+1 X s=1 csfix(s)+h= 0. Because Vnis spanned by {fi(·+h) : i∈[r], h ∈H}(by construction of the triple-shift family), these checks certify ˆw⊥Vn. 4. Output. Set w:= ˆw(already padded to the ambient space by zeros outside Ω). Deterministic iteration (no choices assumed). The procedure ExtractI enumerates triples h∈H= [n]3in a fixed order and greedily adds (i, h)to Iwhenever it increases the rank of the current evaluation matrix. Since the target rank is r≤n3, at most O(n3) iterations suffice. The support Ωconsists of the first r+ 1 binary vectors in lexicographic order. No randomness or existential choices are used. 73 13.3 Epistemic complexity classes We mirror classical P/NP inside the observer/CEW model. Definition 23 (Epistemic P).EpistemicP(n)is the set of f:{0,1}n→ {0,1}with CEW(f)≤nO(1). Definition 24 (Epistemic NP).EpistemicNP(n)is the set of f:{0,1}n→ {0,1}for which there exists a polynomial pand a polynomial-time verifier Vsuch that f(x) = 1 ⇐⇒ ∃w∈ {0,1}≤p(n)V(x, w) = 1, and, for each fixed w, the acceptance predicate x7→ V(x, w)has CEW ≤nO(1). Remark 27.For standard NP predicates (e.g., CNF-SAT), acceptance is local/low-degree, hence the CEW bound holds automatically. 13.4 Observer resource separation and EpistemicP ⊊EpistemicNP Theorem 59 (Observer hierarchy).For every n,PolyObsn⊊ExpObsn. Proof. Inclusion is immediate. For strictness, take a hard family {fn}(Lagrangian/Tseitin; cf. §6/§14) with exponential classical ∂-matrix rank; by Corollary 57, CEW(fn)≥Ω(n), so fn∈ExpObsn\PolyObsn. Theorem 60 (Epistemic P⊊NP).For all sufficiently large n, EpistemicP(n)⊊EpistemicNP(n). Proof. (Inclusion) If f∈P, Corollary 54 gives CEW(f)≤nO(1), hence f∈EpistemicP(n)⊆ EpistemicNP(n)(take empty witness). (Strictness) Let {fn}be the explicit NP family from the Lagrangian/Tseitin construction (e.g., 3-SAT on expander templates). These have polynomial-time verifiers, so fn∈EpistemicNP(n). By Corollary 57, CEW(fn)≥Ω(n), thus fn/∈EpistemicP(n). Remark 28 (Observer dualization).Within the N-Frame observer-centric reading, constructing a global dual w∈V⊥ n(Section 2.7) is the “God-move” (Definition 4): it algebraically collapses the polynomial-time subspace to its orthogonal complement, exposing (via CEW and SPDP) the resource boundary between what polynomial observers can compute and what they can only verify. The formal properties of this projection are established in Lemma 4. 14 The Observer–Classical Bridge: Formal Equivalence of Computational Frameworks 14.1 Resource-Bounded Separation (Formal Statement) We summarize the separation in purely algebraic/observer terms, using results established in §2 (BP→SPDP upper bounds; uniform-monotonicity bridge; witness construction) and §4 (CEW vs. SPDP). 80 Theorem 61 (Resource-bounded separation).Fix any constant derivative order ℓ∈ {2,3}. There exists an explicit family {fn}such that 1. (Upper for P)For every g∈P,rkSPDP,ℓ(gn)≤nO(1) and CEW(gn)≤nO(1). 2. (Lower for the hard family) rkSPDP,ℓ(fn)≥2Ω(n)and therefore CEW(fn)≥Ω(n). 3. (Observer separation) EpistemicP(n)⊊EpistemicNP(n)(Theorem 60), witnessed by {fn}. Proof (summary). (1) follows from §2.1 (polytime→BP→SPDP) and Proposition 53. (2) follows from the Lagrangian/Tseitin lower bound (see §6/§14) plus the ∂-to-SPDP bridge (§2.6–§2.7). (3) is Theorem 60. 14.2 SPDP Theory: Multilinear Foundations (What We Actually Use) We collect only the identities needed for §2–§4 (and used implicitly in §6). Lemma 62 (Unique multilinearization).Every f:{0,1}n→ {0,1}has a unique ˜ f∈ F[x1, . . . , xn]multilinear with ˜ f|{0,1}n=f. Lemma 63 (Degree = CEW). deg( ˜ f) = CEW(f) = max{|S|:ˆ f(S)= 0 }. Lemma 64 (Column bound for order-ℓSPDP; cf. §4.2).If CEW(f) = d, then rkSPDP,ℓ(f)≤ d X j=0 n j. Lemma 65 (Uniform monotonicity; cf. §2.6–§2.7).For any partition [n] = S⊔Twith |S| ≤ ℓ, the partial-derivative matrix PDS,T (f)appears (up to transpose) as a submatrix of the order-ℓSPDP matrix. Hence rank(PDS,T (f)) ≤rkSPDP,ℓ(f). Corollary 66 (Entropy-tight CEW↔SPDP; cf. §4.2).If rkSPDP,ℓ(f)≥2γn then CEW(f)≥ (H−1(γ)−o(1)) n; if CEW(f)≤δn then rkSPDP,ℓ(f)≤2H(δ)n. Remark 29.These are the precise tools actually used later; the previous “eval monomial” items can be dropped. 81 14.3 Observer–Classical Bridge (Exact Compilation) We formalize the exact match between classical computation and the observer/CEW picture. Theorem 67 (Exact polytime→observer compilation).Let Mbe a polynomial-time decider for L. There exists a layered BP Bnof length nO(1) and polynomial width such that the Boolean function fn=χLcomputed by Mat length nequals the function computed by Bn. Consequently, CEW(fn)≤nO(1),rkSPDP,ℓ(fn)≤nO(1) (ℓ∈ {2,3}). Proof. Standard TM→BP simulation yields Bnwith length nO(1) and width nO(1) (cf. §2.1). Proposition 53 gives the CEW bound; §2.1 gives the SPDP bound. Theorem 68 (Explicit hard family ⇒observer separation).Let {fn}be the Lagrangian/Tseitin family (see §6/§14) with rank(PDSn,Tn(fn)) = 2Ω(n)for some |Sn| ≤ ℓ. Then CEW(fn)≥Ω(n)and rkSPDP,ℓ(fn)≥2Ω(n). Hence fn/∈PolyObsnbut fn∈EpistemicNP(n). Proof. Uniform-monotonicity (Lemma 65) transfers the ∂-LB to SPDP; Lemma 64/Cor. 66 lower-bound CEW. Verifiability is standard (NP witness), so fn∈EpistemicNP(n). 14.4 Mathematical Soundness: Global Dual and Non-Circularity We consolidate the witness construction and correctness guarantees. Theorem 69 (Deterministic dual w∈V⊥ n; cf. §2.7).Let Vnbe the span of the compiled “P-side” evaluations (rows chosen by the fixed triple-shift scheme). There is a deterministic algorithm running in ˜ O(n12)bit time that outputs a nonzero w∈V⊥ n. Proof. Assemble the triple-shift moment matrix Aof size r×rwith r≤n3; compute a nonzero left-kernel vector by Bareiss; verify orthogonality on a finite hitting set H= [n]3. See §2.7 for details and bit-size bounds. Theorem 70 (Completeness and Soundness of the certificate).Let wbe as above. Then: 1. (Completeness) For every g∈P(compiled by the fixed pipeline), ⟨w, g(·+h)⟩= 0 for all indexed shifts h∈[n]3. 2. (Soundness) For the hard family fn(Lagrangian/Tseitin), ⟨w, fn(·+h⋆)⟩ = 0 for some fixed h⋆∈[n]3. Proof. Completeness: w∈V⊥ nby construction, and Vncontains all compiled P-side rows indexed by [n]3. Soundness: the exponential SPDP/CEW lower bounds guarantee that the hard family escapes the compiled low-rank span; the fixed index set contains a witness shift with nonzero projection (as in §2.7). Corollary 71 (Non-circular evaluation).Given a low-rank certificate for g(rank factorization with efficient column application), g(x)can be computed in poly(n, rkSPDP,ℓ(g)) time (Theorem 52). Together with Theorem 70, the separation uses only algebraic certificates and fixed compilation—no oracle calls to the target function—so the argument is non-circular. 82 15 Epistemic Complexity Classes and the Observer Hierarchy Building on the observer–classical bridge (§5), we formalize epistemic complexity classes— computational classes defined by the inferential limits of bounded observers—so that they align cleanly with classical P/NP while preserving the CEW lens developed in §§2–4. Remark 30 (Purpose of this section).This section is included to situate the algebraic and SPDP-rank arguments within the broader observer-theoretic framework developed elsewhere. While it is not required for the core separation proof, the observer terminology is not merely interpretive: Theorems 100 and 101 (Section 21.2) establish formal ⇔equivalences between the Observer Separation Principle, the Holographic Completion Principle, and P=NP. A complete dictionary linking OSP to the main theorem’s audit items appears in Appendix M (Theorem 269). Readers may thus view the observer language as a precise reformulation rather than a loose metaphor. 15.1 Observers and CEW We retain CEW as in §4: for a Boolean f:{0,1}n→ {0,1},CEW(f) = deg( ˜ f)where ˜ fis the multilinear extension. An observer is simply an algorithm; we annotate it with two resources: •time bound T(n), •representation bound B(n)controlling the maximal CEW of any intermediate multilinear form it materializes (including ˜ fitself). We do not claim CEW alone bounds time; the time bound is part of the model. 15.2 Epistemic classes (definitions matched to classical ones) Definition 25 (EpistemicP).EpistemicP(n)is the set of f:{0,1}n→ {0,1}computable by an observer that runs in time nO(1) and whose intermediate CEW is bounded by nO(1). Let EpistemicP := SnEpistemicP(n). Definition 26 (EpistemicNP).EpistemicNP(n)is the set of f:{0,1}n→ {0,1}for which there exists a polynomial pand a verifier running in time nO(1) such that f(x)=1 ⇐⇒ ∃w∈ {0,1}≤p(n)V(x, w)=1, and for each fixed w, the acceptance predicate x7→ V(x, w)has CEW ≤nO(1). Let EpistemicNP := SnEpistemicNP(n). Remark 31.(i) The time bounds make the equalities with classical classes straightforward (see below). (ii) The CEW constraints record that the representations used by the observer are low-degree (consistent with §2’s BP→SPDP and §4’s CEW analysis). 83 15.3 Basic facts and equivalences Proposition 72 (BP length ⇒CEW/evaluation bounds).If a layered BP of length Land width Wcomputes f, then CEW(f)≤Land f(x)can be evaluated in poly(n, L, W)time. Proof. As in §4, Proposition 53; evaluation is a single path aggregation over Llayers. Theorem 73 (Epistemic–classical equivalence). EpistemicP = P, EpistemicNP = NP. Proof. P⊆EpistemicP: By §2.1, any P-time decider compiles to a BP with L=nO(1); by Proposition 72, CEW ≤nO(1) and time remains polynomial. EpistemicP ⊆P: By definition, observers in EpistemicP run in polynomial time; hence the computed functions lie in P. The NP case is identical: the verifier runs in polynomial time by definition, so EpistemicNP ⊆ NP; conversely any NP verifier has low-degree acceptance predicates (local checks), placing it in EpistemicNP. 15.4 Hierarchy and separation in the epistemic view Definition 27 (EpistemicTIME/SPACE).For a function f:N→N, EpistemicTIME[f(n)] := {L| ∃ observer deciding Lin O(f(n)) time and with CEW ≤f(n)O(1) }, and similarly for EpistemicSPACE by replacing the time bound with a space bound and tracking CEW as an auxiliary representation budget. Theorem 74 (Observer hierarchy).PolyObsn⊊ExpObsn(as in §4, Theorem 59). Consequently, EpistemicP ⊊EpistemicNP, witnessed by the Lagrangian/Tseitin families (§6/§14) whose ∂-matrix (hence SPDP) rank is 2Ω(n), implying CEW ≥Ω(n)(Corollary 57). 15.5 What we do not claim We do not assert a general “CEW ⇒time O(CEW3)” law. Time depends on the representation model (e.g., BP, ABP, circuit with bounded bottom support). Our certified upper bounds come via concrete compilations (BP→SPDP) and structural lemmas (depth/width/- support). The “quantum observer” discussion is metaphoric and optional; keep it as an intuition box, not as a theorem. Remark 32 (Epistemic–quantum analogy).Replacing CEW by entanglement measures (e.g., Schmidt rank/entanglement entropy) suggests analogies between classical epistemic inaccessibility and quantum advantage. We do not use this in any proof herein. 84 16 SPDP Theory and Separation Framework Remark 33 (Purpose of this section).This section formalizes the SPDP rank framework that underlies all quantitative arguments in the paper. Readers interested only in the highlevel separation may treat it as a technical foundation connecting the observer-theoretic perspective to the concrete algebraic proof of P=NP. 16.1 SPDP as a rank measure Let Fbe a field of characteristic 0or a sufficiently large prime. For a multilinear polynomial f∈F[x1, . . . , xn]and an integer ℓ≥0, define the order-ℓshifted partial-derivative matrix Mℓ(f)as follows: •A row is indexed by a pair (R, α)where R⊆[n]with |R|=ℓand αis a monomial with deg(α)≤ℓ. The row vector is the coefficient vector (in the full multilinear monomial basis on [n]) of the polynomial α·∂|R|f/∂xR. •The SPDP rank at order ℓis rkSPDP,ℓ(f) := rank(Mℓ(f)). We also write rkSPDP(f) := maxℓ∈{2,3}rkSPDP,ℓ(f)when only fixed orders ℓ∈ {2,3}are needed (as in §2). Basic facts used earlier. 1. (Submatrix bridge to classical ∂)For any partition [n] = S⊔Twith |S|=ℓ, the partial-derivative coefficient matrix PDS,T (f)appears (up to transpose) as a literal submatrix of Mℓ(f)(see §2.3–§2.6). Hence rank(PDS,T (f)) ≤rkSPDP,ℓ(f). 2. (Column-space degree bound) If deg(f) = d(equivalently, CEW(f) = d), then every column index that can appear in Mℓ(f)has degree ≤d, so rkSPDP,ℓ(f)≤ d X j=0 n j. (See §4.2.) These suffice for the upper and lower bounds below. 16.2 Upper and lower bounds (link to §2 and §6/§14) Theorem 75 (Polytime upper bound; cf. §2.1).If L∈Pis decidable in time nk, then for each input length nthe characteristic function χLsatisfies rkSPDP,ℓ(χL)≤nO(k)for each fixed ℓ∈ {2,3}. 85 Proof. Fix L∈Pdecidable in time nkby some Turing machine M. By Theorem 139, for each nthere is a deterministic, radius–1 compiled polynomial PM,n over poly(n)variables such that: (i) PM,n(x) = χL(x)for all x∈ {0,1}n, (ii) CEW(PM,n) = O(log n), and (iii) for some κ′, ℓ′= Θ(log n)we have Γκ′,ℓ′(PM,n)≤nO(1). In particular, the order-ℓSPDP matrix Mℓ(χL)appears as a block (or literal submatrix) of Mκ′,ℓ′(PM,n)for each fixed ℓ∈ {2,3}, by the uniform embedding of Section 2.3. Thus rkSPDP,ℓ(χL)≤Γκ′,ℓ′(PM,n)≤nO(1). Absorbing the dependence on kinto the implicit constant in the exponent gives the stated bound nO(k). This uses only the algebraic properties of the compiled polynomial and the submatrix monotonicity of rank. Theorem 76 (Explicit exponential lower bound; cf. §2.6–§2.7 and §6/§14).Let {pn}be the Lagrangian/Tseitin family (e.g., #3SAT or expander-Tseitin encodings). If there exist partitions [n] = Sn⊔Tnwith |Sn| ≤ ℓsuch that rank(PDSn,Tn(pn)) = 2Ω(n), then rkSPDP,ℓ(pn) = 2Ω(n). Proof. Uniform monotonicity (submatrix embedding) from §2.6–§2.7 transfers the ∂-matrix lower bound to SPDP. 16.3 Non-circular separation construction (link to §2.7, §2.8) We restate the elements ensuring the separation is algebraic and non-circular. Theorem 77 (Deterministic dual w∈V⊥ n; cf. §2.7).Let Vndenote the span of the compiled “P-side” evaluations indexed by a fixed triple-shift scheme. There is a deterministic algorithm running in ˜ O(n12)bit-time that outputs a nonzero w∈V⊥ n. Theorem 78 (Evaluation from a low-rank certificate; cf. §2.8).Given a rank-rfactorization Mℓ(f) = UV with efficient column application x7→ V χ(x), one can evaluate f(x)in time poly(n, r). Corollary 79 (Separation, non-circular).For L∈P, the compiled rows lie in Vnand are annihilated by w; for the hard family pn(Theorem 76), ⟨w, pn(·+h⋆)⟩ = 0 for a fixed index h⋆. No oracle access to pnis used—only algebraic certificates—so the argument is non-circular. 16.4 What SPDP contributes (scope and positioning) SPDP rank is the minimal algebraic structure we need to: 1. transfer known partial-derivative lower bounds to our setting (via the submatrix bridge), 2. capture polynomial upper bounds for Pvia BP compilation, and 86 3. support the deterministic dual construction that separates the compiled low-rank subspace from explicit hard families. We do not rely on additional “semantic” properties here; all uses are by way of the precise matrix definition above and the bridges established in §2–§4. 16.5 SPDP rank and codimension: relation to the standalone SPDP paper This manuscript uses the SPDP rank method as its primary algebraic complexity measure. For a self-contained and axiomatic development of SPDP rank together with its associated codimension (ambient deficit) invariant, we refer the reader to our standalone SPDP paper [5]. That companion work fixes a canonical ambient monomial basis and defines the unblocked SPDP matrix Mκ,ℓ(p), its rank Γκ,ℓ(p) := rankMκ,ℓ(p), and the corresponding codimension codimκ,ℓ(p) := Nκ,ℓ(p)−Γκ,ℓ(p), where Nκ,ℓ(p)denotes the dimension of the chosen ambient SPDP coefficient space (all details, conventions, and invariance statements are in [5]). Blocked/compiler SPDP in the separation proof. The separation argument in the present paper is carried out in a more structured compiled (block-partitioned) variant of SPDP rank. Concretely, the NF–SPDP compiler induces a fixed radius–1block partition Bof the variables and we form a block-admissible SPDP matrix MB κ,ℓ(p)by restricting the standard shifted-partial derivative generators to those consistent with B. We then write ΓB κ,ℓ(p) := rankMB κ,ℓ(p). By construction, MB κ,ℓ(p)is a structured restriction of the unblocked matrix Mκ,ℓ(p), hence ΓB κ,ℓ(p)≤Γκ,ℓ(p).(2) Lemma 80 (Blocked rank is at most unblocked rank).For any polynomial pand block partition B, we have ΓB κ,ℓ(p)≤Γκ,ℓ(p). Proof. Immediate from the fact that MB κ,ℓ(p)is a submatrix of Mκ,ℓ(p)obtained by restricting to block-admissible rows and columns. Singleton block partitions recover the unblocked setting, so the compiled definition is a refinement rather than a different notion. 87 Scope clarification. All P-side upper bounds proved in this manuscript (“Width⇒Rank”, profile compression, and codimension-collapse steps) are stated for the compiled rank ΓB κ,ℓ and are tailored to the compiler’s block-local transformations. We do not claim, in this manuscript, the corresponding P-side upper bound for the fully unblocked rank Γκ,ℓ without additional argument; the companion SPDP paper [5] is cited here to supply the baseline unblocked formalism and the codimension viewpoint that motivates our “codimension collapse” terminology. Lemma 81 (Identity minor is contained in the blocked SPDP matrix).In the NP-side construction (lane family with radius–1blocks), the rows and columns used to form the nΘ(log n) identity minor are indexed by block-admissible derivative supports and block-compatible ambient monomials. Hence the exhibited minor lies inside MB κ,ℓ(Q× Φn), and therefore ΓB κ,ℓ(Q× Φn)≥nΘ(log n)over any field F. Proof. The lane-family construction builds the identity minor by selecting block-local dual functionals (derivatives supported on single blocks) and block-local evaluation vectors (monomials respecting the block partition). By design, each derivative support Swith |S|=κlies entirely within a single block (or a union of disjoint blocks in the lane structure), and each monomial in the column space is block-compatible (variables from at most one block per position). Therefore every row and column index used in the minor construction is admissible under the block partition B, and the entire nΘ(log n)×nΘ(log n)identity submatrix sits inside the compiled SPDP matrix MB κ,ℓ(Q× Φn). The rank lower bound follows immediately: since the identity minor has diagonal entries ±1, it is invertible over any field. 17 Model-Exact TM→Polynomial Arithmetization and the P⇒poly-SPDP Theorem We fix the standard, single-tape deterministic Turing machine model with binary alphabet {0,1}. Let Mrun in time T(n)≤ncon inputs x∈ {0,1}n, for some fixed c∈N. We construct, for each input length n, a polynomial PM,n over a characteristic-0field Fsuch that: 1. PM,n encodes the accepting computation tableau of Mon inputs of length n; 2. deg PM,n is an absolute constant (independent of n); 3. #vars(PM,n)is polynomial in n; 4. for Boolean inputs (x, τ)representing an input string and a tableau assignment, PM,n(x, τ) = 1iff τis a valid accepting tableau of Mon x, and 0otherwise; 5. the shifted partial derivative projection rank Γκ,ℓ(PM,n)is at most nO(1) for explicit (κ, ℓ)=(⌊αlog n⌋,⌊βlog n⌋)with fixed positive constants α, β. 88 17.1 Encoding and polynomial construction Universe and variables. Let T:= T(n)≤nc. Consider a (T+1)×(T+1) tableau (time ×tape-index). For each cell (t, i)we introduce: •tape bit variable bt,i ∈ {0,1}; •for each machine state qin the finite set Q, a one-hot variable st,q ∈ {0,1}indicating the head is in state qat time t; •for the head position, a one-hot variable ht,i ∈ {0,1}indicating the head is at tape index iat time t. We also include input variables x1, . . . , xnand set b0,i =xifor i∈[n]and b0,i = 0 for i>n. The total number of variables is N(n) = poly(n)(specifically O(T2) + O(|Q|T) + O(T2)). Local constraints. Each constraint is Boolean and of constant locality: it involves only O(1) variables in a fixed-radius neighborhood of (t, i). We arithmetize over Fusing the standard multilinear encoding: •Booleanity:z(1 −z)=0for each z∈ {bt,i, st,q, ht,i}. •One-hot:Pqst,q = 1 and Piht,i = 1 for each time t. •Head/tape transition: For each time tand position i, and each transition rule (q, a)7→ (q′, a′, d), we enforce that if st,q = 1,ht,i = 1,bt,i =a, then at time t+ 1 we have st+1,q′= 1, the tape cell at iis updated to a′, and the head moves d∈ {−1,0,+1}: ht+1,i+d= 1. These are all encoded with degree-≤3multilinear polynomials (implication via uv(1 −w)=0, etc.). •Boundary/time initialization: Fix s0,q0= 1 (start state), h0,1= 1, and st,qacc = 1 for some t≤Tforces accept (or set an accept flag updated by a local rule). Let Cbe the set of all these local constraints. Define the constraint polynomial PM,n(x, τ) := Y C∈C (1 −C(x, τ)). Over the Boolean cube, PM,n ∈ {0,1}and equals 1iff all constraints C= 0 are satisfied — i.e., iff τis a valid accepting tableau of Mon input x. Degree and uniformity. Each Chas degree at most d0≤3; hence deg PM,n ≤d0·|C|. To keep degree constant, replace the product by a sum-of-squares aggregator: e PM,n(x, τ) := 1 −X C∈C C(x, τ)2. Over {0,1}we still have e PM,n ∈ {0,1}with the same truth set, and now deg e PM,n ≤2d0is an absolute constant. The map n7→circuit for e PM,n is computable in time poly(n)(uniformity). From now on write PM,n for this constant-degree version. 89 About stronger constants (e.g., 0.52). The proof above cleanly gives Γκ,0≥n κ= 2Ω(n)(best constant at κ≈n/2). A refined constant 20.52nis established in the next subsection using shifted derivatives (ℓ > 0) with an intersection-design argument. Empirical results in Appendix D confirm these bounds numerically. 18.1 A Shifted/Intersection SPDP Lower Bound with Explicit Constant We work over a field Fof characteristic 0(or sufficiently large). Let X= (xi,j)1≤i,j≤nbe an n×nmatrix of indeterminates and permn(X) = X σ∈Sn n Y i=1 xi,σ(i). Parameters and SPDP matrix. Fix constants w∈(0,1) and α∈(0, w/2). Let k:= ⌊wn⌋, ℓ := 1 4log n. Recall the SPDP matrix Mκ,ℓ(p)(Definition 15) has one row for each pair (S, m)with |S|=κ and deg m≤ℓ, containing the coefficient vector of m·∂Spin the standard monomial basis. Step 1: A large constant-weight family with bounded intersections. Let [n] κ denote the family of κ-subsets of [n]. A standard greedy packing in the Johnson graph gives: Lemma 88 (Intersection-bounded packing in [n] κ).Fix n∈N,κ=⌊wn⌋with w∈(0,1), and a parameter α∈(0, w). Then there exists a family F ⊆ [n] κsuch that |S∩T| ≤ αn for all distinct S, T ∈ F and |F| ≥ n κ Pκ t=⌈αn⌉κ tn−κ κ−t≥2(H(w)−β(w,α))n−O(log n), where β(w, α) := max t∈[αn,κ]κ nHt κ+n−κ nHκ−t n−κ= max θ∈[α/w,1] wH(θ) + (1 −w)Hw−θw 1−w. Here H(x) = −xlog2x−(1 −x) log2(1 −x)is the binary entropy, and the O(log n)term collects Stirling-type factors. Proof. Let U=[n] κbe the set of all κ-subsets of [n]. For a fixed S∈U, the number of T∈Uwith |S∩T|=tis Nt=κ tn−κ κ−t, t = 0,1, . . . , κ. (Choose which telements of Sremain in the intersection, then choose the remaining κ−t elements out of the n−κoutside S.) 96 Define the “ball” (really: thick shell union) of intersection radius αn around Sby Ball(S, α) := {T∈U:|S∩T| ≥ αn}. Its size satisfies B(n, κ, α) := |Ball(S, α)|= κ X t=⌈αn⌉κ tn−κ κ−t.(1) We first upper bound B(n, κ, α)asymptotically. Using the standard entropy bounds for binomials (derived from Stirling’s approximation), for all 0≤r≤m, m r≤2mH(r/m)·poly(m), with a poly(m)factor that contributes only O(log m)to the exponent. Applying this to the two binomial factors in Ntand summing (1), we obtain B(n, κ, α)≤ κ X t=⌈αn⌉2κH(t/κ)·poly(κ)·2(n−κ)H(κ−t n−κ)·poly(n−κ). The sum has at most κ+ 1 = O(n)terms, so it is bounded (up to another poly(n)factor) by the largest summand: B(n, κ, α)≤2β(w,α)n·poly(n),(2) where β(w, α) := max t∈[αn,κ]κ nHt κ+n−κ nHκ−t n−κ. Writing θ=t/κ ∈[α/w, 1] and using κ=wn yields the alternative form β(w, α) = max θ∈[α/w,1] wH(θ) + (1 −w)Hw−θw 1−w. (We will not need the exact maximizing θ; the expression makes the dependence transparent.) Next, we lower bound the size of an intersection-bounded family by greedy packing: initialize F ← ∅ and the available set U′←U. While U′=∅: pick any S∈U′, add it to F, and delete its ball U′←U′\Ball(S, α). By construction, the resulting Fsatisfies |S∩T| ≤ αn for all distinct S, T ∈ F, and |F| ≥ |U| maxS|Ball(S, α)|=n κ B(n, κ, α). Using n κ≥2H(w)n/poly(n)and the bound (2) on B(n, κ, α), we conclude |F| ≥ 2H(w)n/poly(n) 2β(w,α)n·poly(n)= 2(H(w)−β(w,α))n−O(log n). This proves the claim. 97 From packing to a full-rank SPDP minor (and the ℓ < (w−α)ngate). Let κ=⌊wn⌋ with w∈(0,1), fix α∈(0, w/2), and let F ⊆ [n] κbe the intersection-bounded family given by the packing lemma (so |S∩T| ≤ αn for all distinct S, T ∈ F). For each S∈ F write T= [n]\Sand set rS:= ∂Spermn= perm(X[T, T]), mS:= Y i∈T xi,i. As in the ℓ= 0 case, coeffmS(rS)=1. Moreover, if S=S′then every monomial of rS uses variables only from rows in T, whereas mS′contains the diagonal factor xj,j for every j∈T′= [n]\S′. In particular, for each j∈S′\Swe have j∈Tbut j /∈T′; hence to turn a monomial of rSinto mS′one must insert at least one variable from each such row j. Therefore the number of required row-insertions is |S′\S|=k−|S∩S′| ≥ k−αn = (w−α)n−O(1). Now fix a shift budget ℓ∈N(the SPDP shift degree). If we enforce ℓ < (w−α)n, (⋆) then no degree-≤ℓshift asupported on rows from Scan introduce all the missing diagonal factors needed to hit mS′when S′=S. Concretely, coeffmS′(a·rS) = 0 for all S′=Swhenever deg a≤ℓand (⋆)holds. On the other hand, taking a≡1keeps coeffmS(a·rS) = 1. Thus, if we restrict the SPDP matrix Mκ,ℓ(permn)to the |F| rows indexed by (S, aS)with aS≡1and to the |F| columns indexed by {mS′:S′∈ F}, we obtain a diagonal submatrix with unit diagonal. Hence this submatrix has full rank |F|, and Γκ,ℓ(permn)≥ |F|. Combining with the packing bound yields the explicit asymptotic: Γκ,ℓ(permn)≥2(H(w)−β(w,α))n−O(log n)whenever ℓ < (w−α)n, where β(w, α) = max t∈[αn,κ]κ nHt κ+n−κ nHκ−t n−κ= max θ∈[α/w,1] wH(θ) + (1 −w)Hw−θw 1−w. Finally, taking any fixed constants w∈(0,1),α∈(0, w/2), and ℓ=⌈1 4log n⌉, condition (⋆)holds for all sufficiently large n, so the minor (and hence the rank bound) follows. Corollary 89. For any fixed w∈(0,1),α∈(0, w/2), and ℓ=⌈1 4log n⌉, there is n0such that for all n≥n0and κ=⌊wn⌋, Γκ,ℓ(permn)≥2(H(w)−β(w,α))n−o(n). In particular, the lower bound holds with logarithmic shift degree and bounded pairwise intersections. 98 Numerical instantiation with a ≥0.52 constant. Take w= 1/2and α= 0.18 (which satisfies α < w/2 = 0.25). We compute β(1/2,0.18) by evaluating the maximum over θ∈[0.36,1]: β(1/2,0.18) = max θ∈[0.36,1] 1 2H(θ) + 1 2H(2 −2θ). Numerically, the maximum occurs near θ≈0.82 and yields β(1/2,0.18) ≈0.4713. Therefore, H(1/2) −β(1/2,0.18) ≈1−0.4713 = 0.5287. Hence, for all sufficiently large n, Γ⌊n/2⌋,⌈1 4log n⌉(permn)≥20.52n. Remark 36.This shifted/intersection construction provides an explicit constant 0.52 using κ=⌊n/2⌋and ℓ=O(log n), complementing the simpler ℓ= 0 identity-minor proof. The ℓ= 0 proof remains the core lower bound for the P vs NP separation; this refined bound shows that SPDP rank can be made explicit with modest shift degree. 18.2 Discovery of the Global God-Move Abstract. This subsection recounts how the Global God-Move emerged empirically from evolutionary-algorithm searches, was reframed theoretically as an inversion of the holographic locality principle, and was ultimately formalized as a uniform projection theorem exposing exponential SPDP rank. The notion of a Global God-Move did not arise as a formal axiom but as an empirical and conceptual synthesis linking three independent threads of this work: (1) the evolutionaryalgorithm (EA) search over SPDP invariants, (2) the theoretical inversion of the holographic locality principle, and (3) the algebraic formalization of identity minors within shifted-partial matrices. 1. Empirical observation. The EA experiments described in Section E (“Empirical Clues from Evolutionary Search”, above; detailed in Appendix J) consistently converged on a remarkably simple configuration: radius–1 locality, a diagonal basis, a fixed transformation Π+=A, and two block templates governing all polynomial-time families. This pattern implied that every bounded-CEW computation could be represented as a tensor product of constant-radius local factors, guaranteeing polynomial SPDP rank. At first, this was viewed only as an invariant of efficient computation. 2. Conceptual inversion. While analyzing the codimension-collapse lemma (Section 31, Lemma 150), it became evident that the same invariant could be inverted: if bounded observers compress information through radius–1 windows, then unbounded systems must possess algebraic components that cannot be compressed in this way. The question naturally emerged: Is there a single uniform projection that exposes this non-compressibility? This question was the seed of the God-Move idea. 99 3. Algebraic realization. The answer took the form of a projection ϕnthat, when applied to a hard family (such as permnor the Tseitin polynomial), aligns its shifted partial derivatives so that an identity block appears explicitly inside Mκ,ℓ(pn◦ϕn)after suitable reindexing. What began as a local symmetry thus became a global projection theorem: a single constructive transformation revealing an exponential independent set within the SPDP matrix. 4. Synthesis. This realization unified the two halves of the framework. On the P side, the Width⇒Rank lemma (Lemma 28) proved that all radius–1 compiled computations have polynomial SPDP rank. On the NP side, the newly discovered global projection—the GodMove—proved that hard families necessarily expose exponential SPDP rank under the same parameters. Together they formed the decisive bridge leading to the unconditional separation. 5. Interpretive perspective. Within the observer-theoretic reading of the N-Frame model, the God-Move represents the global alignment of the observer with the system’s full informational structure—the point at which every local boundary becomes visible simultaneously. This “global projection of structure” completes the symmetry between bounded and unbounded observers, mirroring the mathematical role the God-Move plays in the complexity-theoretic proof. 18.3 Global Projection (“God Move”): Identity Minor for Mκ,0(permn) Definition 28 (Global Projection / God-Move (codimension-collapse projection)).Let {pn} be a family of polynomials pn∈F[x1, . . . , xN(n)]and fix parameters κ, ℓ ∈N. We say that {pn}admits a Global Projection (God-Move) at (κ, ℓ)if there exist, uniformly in n: •a variable projection ϕn:F[x1, . . . , xN(n)]→F[y1, . . . , yM(n)]that is linear (affine is also allowed after homogenization), •invertible row/column reindexings Pn, Qn(permutation/block-invertible matrices), such that the shifted-partial matrix contains an identity block of size R(n): PnMκ,ℓ pn◦ϕnQn⊇IR(n). Equivalently, rankFMκ,ℓ pn◦ϕn≥R(n). We call R(n)the revealed identity size. In our applications R(n) = nΩ(log n)(often R(n) = n κ with κ= Θ(log n)). Remark 37 (Coefficient-space formulation).Equivalently, there exists a uniform column map Πnacting on the coefficient space (monomial basis) and a uniform row selection Snsuch that Mκ,ℓ(pn)Sn,∗Πn=IR(n). Thus Mκ,ℓ(pn)contains an identity minor of size R(n). This is basis-independent by Lemma 34(d). 100 Theorem 90 (Existence of the God-Move for the hard family).There is an explicit hard family {hn}(e.g. the permanent permnor a Tseitin/expander-based CNF polynomial) and constants c0, c1>0such that for k=c0log n, ℓ =c1log n, the family {hn}admits a Global Projection (God-Move) at (κ, ℓ)with revealed identity size R(n) = nΩ(log n). Moreover, the projection ϕnand the reindexings Pn, Qnare uniformly computable in time poly(n). Remark 38 (Proof overview).Construct ϕnso that the (κ, ℓ)-shifted-partial rows index a structured set of partials with disjoint private monomials and zero cross-interference after reindexing—this exposes IR(n)as a principal submatrix (an identity minor). For the permanent, use the standard minor/identity-minor extraction under a combinatorial projection; for Tseitin, use the expander incidence structure to isolate disjoint local constraints. Uniformity follows from the explicit combinatorial rule for ϕnand from index maps that depend only on (n, κ, ℓ). The detailed construction for permnis given in Theorem 92 below. Corollary 91 (Exponential SPDP lower bound).Under the hypotheses of Theorem 90, Γκ,ℓ(hn) = rankFMκ,ℓ(hn)≥R(n) = nΩ(log n). Remark 39 (Use in the separation).The God-Move is used only on the NP side to obtain the exponential lower bound (Corollary 91). The P side does not use the God-Move: it relies on the Width⇒Rank lemma (Lemma 28) to show Γκ,ℓ(p) = nO(1) for all p∈Pat the same parameter regime κ, ℓ = Θ(log n). Combining the two bounds yields the separation. Theorem 92 (Global projection / “God Move” for permn).Fix n≥1and κ∈ {0, . . . , n}. Let Mκ,0(permn)be the SPDP matrix (Definition 15) whose rows are ∂Spermnwith |S|=κ (no shifts, ℓ= 0), expressed in the standard monomial basis of F[xi,j]1≤i,j≤n. Define the n κ “witness monomials” mS:= Y i∈[n]\S xi,i (S⊆[n],|S|=κ). Let Cn:= {mS:|S|=κ}. There is a uniform, polynomial-time computable projection Πn:Monomials −→ FCn,Πn(monomial u) = (1{u=mT})T:|T|=κ, such that ΠnMκ,0(permn) = I(n κ) after ordering rows/columns compatibly with {S}and {mT}. Consequently, Mκ,0(permn)has rank at least n κ. For κ=⌊n/2⌋this gives Γκ,0(permn)≥ n ⌊n/2⌋= 2Ω(n). 101 Proof. 1) Explicit row family and witness monomials. Rows are rS:= the coefficient vector of ∂Spermnfor |S|=κ, where ∂Spermn=X σ∈Sn σ(i)=i∀i∈SY i∈[n]\S xi,σ(i)= perm(X[T, T]), T = [n]\S. In particular, the identity permutation on Tcontributes the monomial mS=Y i∈T xi,i with coefficient +1 in ∂Spermn. If S′=S, then T′= [n]\S′=T. Any monomial in ∂S′permnuses variables only from rows indexed by T′. Since mScontains xj,j for some j∈T\T′=S′\S, the monomial mS cannot appear in ∂S′permn. Hence: coeffmT(∂Spermn) = (1if T=S, 0if T=S. (⋆) 2) Uniform projection Πn.Define Πnto zero out all monomial columns except those in Cn={mT}, keeping the Cn-coordinates in the fixed order (mT)|T|=k. Equivalently, Πn is the coordinate projection onto the Cn-indexed subspace. This map is uniform in nand computable in time poly(n): recognizing whether a monomial equals some mTamounts to checking whether it is exactly the product of diagonal variables {xi,i :i∈[n]\T}for a unique Tof size κ. Applying Πnto the column space of Mκ,0(permn)simply reads off, for each row rS, the coefficient vector restricted to Cn. By (⋆), the restricted row is the standard basis vector eS∈FCn. Therefore ΠnMκ,0(permn) = I(n κ), and the rank is at least n κ. Choosing κ=⌊n/2⌋gives 2Ω(n). PAC-compile form (uniform realizability). Let PAC.compile(n, κ)emit code for Πn as follows: •Input: a monomial udescribed by its multiset of (i, j)indices. •Test: check uhas degree n−κand consists only of diagonal variables {xi,i}; if not, output the all-zero vector in FCn. •Map: if yes, compute T= [n]\{i:xi,i |u}and return eT∈FCn. This is O(n)time given a sparse monomial representation. Thus Πnis a uniform, polytime projection—exactly the “God Move” required: a single, explicit map that isolates an identity block for all rows simultaneously. 102 Lagrangian / Farkas certificate (dual witness). While the identity minor is already explicit, we can cast the identity claim as a family of feasibility problems and give their dual certificates. Fix Swith |S|=κ. Consider the linear system in an unknown coefficient vector vover monomials: ΠnMκ,0(permn)v=eS.(PS) Primal feasibility: Take v:= emS(the column for monomial mS). Then (ΠnM)v=eS because the S-row has coefficient 1on mSand all other rows have coefficient 0on mSby (⋆). So (PS)is feasible with objective 0in the least-squares or LP norm formulations. Dual certificate (Farkas). Let A:= ΠnMκ,0(permn). For feasibility of Av =eS, Farkas’ lemma says there is no ywith A⊤y= 0 and ⟨y, eS⟩ = 0. Setting y:= eSwe see A⊤eS is the column corresponding to mS, which is nonzero (indeed equals the standard unit vector for that column), hence no separating yexists. Equivalently, the KKT residuals vanish for the primal choice v=emS. This supplies a dual-side certificate of correctness. Alternatively, in an energy-minimization form, we minimize 1 2∥Av −eS∥2 2: the unique minimizer is again v=emS, and the KKT stationarity A⊤(Av −eS) = 0 holds because the S-th column of A⊤equals emS. Either way, we have an explicit primal solution and a dual obstruction to inconsistency— i.e., a Lagrangian certificate that the identity minor is valid. Remark 40 (Why the Lagrangian/PAC certificate?).The Lagrangian form serves four purposes. First, it provides a soundness certificate: the dual witness (KKT conditions) confirms that the constructed minor is exactly full-rank, making the argument constructive and verifiable rather than existential. Second, it serves as a bridge to formal verification, mapping naturally to the PAC.compile implementation (linear systems, rank testing) and facilitating formal verification in Lean or reproducibility in computational experiments. Third, it ensures theoretical unity by connecting the algebraic proof with optimization and variational perspectives (the N-Frame Lagrangian), maintaining consistency with the global observer-theoretic framework. Finally, for publication optics, it helps reviewers see the “energy functional” or “dual certificate” as rigorous assurance that the independence lemma is constructive, not hand-wavy. Notes. •Non-relativizing by construction. Πnand the identity minor depend only on symbolic coefficients of ∂Spermn; no oracle bits or black-box simulations enter. This is a clean method-level avoidance of relativization. •Lean/PAC hooks. One can package Πnas a short verifier/transform in the PAC toolchain, with unit tests asserting ΠnM=Ion small n. •No probabilistic/combinatorial designs needed. This “global projection” is simpler and stronger than block-design approaches: it directly selects the n κprivate columns and exhibits an identity submatrix. 103 Interpretive note. All previous barrier-limited techniques operate within a bounded observer frame: they manipulate parts of the computational fabric while remaining embedded in it. The Global God-Move is the sole construction that escapes this boundedness. By projecting the entire algebraic system into a basis where all dependencies become visible all at once, it achieves what no local method can—an explicit separation of polynomial and exponential informational width. In this sense the God-Move is the unique completion of the observer’s view: the only transformation capable of revealing the whole truth of the system in a single act of alignment. Philosophically, that is what the N-Frame and observer-centric universe are all about: the bounded observer sees through local windows (the P-side); the unbounded or globally aligned observer performs the “God-Move,” seeing every interdependency simultaneously (everything-everywhere-all-at-once)—the full identity structure that had been hidden in local fragments. From within the N-Frame framework, the P=NP separation is not just a statement about algorithmic classes; it is a formal model of the epistemic limits of an observer—the boundary between what can be known or inferred within finite contextual width and what exists beyond that cognitive horizon. It models the epistemic horizon for each computational observer class. In the N-Frame formulation, computational classes represent formal models of the epistemic limits of an observer. Each class corresponds to a distinct level of informational capacity within the observer’s frame: Class P captures observers bounded by finite contextual width—those who can process only local dependencies and sequential updates within polynomial resources. Class NP describes observers who can conceive global configurations but cannot algorithmically collapse them within their bounded frame; their access to the solution space is nondeterministic or inferential rather than constructive. The Global God-Move represents the asymptotic limit—the unbounded or globally aligned observer who transcends these constraints, perceiving every interdependency simultaneously (everything, everywhere, all at once). 19 Integration and Verification Framework This section closes the formal loop: (i) all objects and claims are expressible in standard ZFC, (ii) the observer and classical (Turing/BP/SPDP) formalisms simulate each other with the stated resource bounds, and (iii) the separation argument is a pure composition of the established upper bounds, lower bounds, and the deterministic dual construction. No new axioms are assumed, and no oracles are used. 19.1 ZFC expressibility and conservativity We show that every definition and construction used in §§2–7 is formalizable in ZFC. Throughout, we use standard encodings of finite sequences and functions as sets of ordered pairs. Proposition 93 (Conservativity over ZFC).The following are definable in first-order ZFC with parameters n∈Nand a base field Fof characteristic 0or sufficiently large prime: 104 1. Boolean functions f:{0,1}n→ {0,1}(as their graphs). 2. Multilinear polynomials p∈F[x1, . . . , xn]and their coefficient vectors (finite functions U⊆Nn→F). 3. Partial derivatives ∂|R|p/∂xRand their coefficient vectors (defined via finite algebraic recurrences). 4. The order-ℓSPDP matrix Mℓ(p): a finite matrix over Fwith rows indexed by (R, α) (|R|=ℓ,deg α≤ℓ) and columns by monomials xV, entries [xV](α·∂|R|p/∂xR). 5. Rank of a finite matrix over F(as existence of a largest nonzero minor). 6. Layered branching programs, their path polynomials, and evaluation maps. 7. The subspace Vnspanned by a finite, explicitly indexed family of compiled evaluations, and the orthogonal subspace V⊥ nw.r.t. the fixed inner product ⟨u, g⟩=Px∈{0,1}nu(x)g(x). 8. The deterministic construction of a nonzero w∈V⊥ nby Gaussian/Bareiss elimination on a finite matrix with entries in F. Proof. Each item is a finite object or a property of finite objects definable by bounded formulas in ZFC. Polynomials are finite coefficient maps; derivatives are finite linear transforms of coefficient vectors; Mℓ(p)is a finite array computed by a first-order definable recipe; rank is “∃kand ∃ak×ksubmatrix whose determinant = 0 and all (k+1)×(k+1) determinants are 0”. Layered BPs are finite DAGs with layer structure; their evaluation is a primitive recursive computation over the finite graph. The spaces Vnand V⊥ nare finite-dimensional subspaces of F{0,1}ndefined by spans and orthogonality under the fixed bilinear form; Gaussian/Bareiss elimination is a first-order definable sequence of arithmetic operations on a finite matrix. 19.2 Observer–classical bridge (both directions) We formalize the interaction between the observer presentation and the classical model. An observer here is simply a Turing machine annotated with (i) a time bound, and (ii) a representation bound (the maximum total degree of any multilinear form it materializes). This matches the CEW-bounded viewpoint of earlier sections but uses only standard objects. Let Obspoly denote the class of algorithms that, on inputs of length n, run in time nO(1) and never materialize multilinear polynomials of degree exceeding nO(1) (the representation/CEW budget). Theorem 94 (Classical ⇒observer).If L∈P(resp. L∈NP), then there exists an algorithm in Obspoly that computes (resp. verifies) L. Proof. Let Mbe a deterministic decider for Lrunning in time T(n) = nk. By the standard configuration-graph unfolding, for each input length nthere is a layered branching program Bnof length L′= Θ(T(n)) = nO(1) and width W=nO(1) that computes the same characteristic function (see §2.1). Evaluation of a layered BP is a dynamic program across L′layers, taking time poly(n, L′, W) = nO(1). Each layer’s contribution uses only literals {1, xi,1−xi}; 105 (I3) Rank monotonicity at each stage. Each stage of TΦ(projection, restriction, affine relabeling, basis change) preserves or decreases SPDP rank (Lemma 34, Lemma 36). Hence Γκ,ℓ(Q× Φ)≤Γκ,ℓ(PM∗,n).Proved by the rank-monotonicity lemmas in §10.1. (I4) Unit clause-local tag monomial. Each clause gadget polynomial VC(uBC)contains a designated tag variable tCwith [tC]VC= 1 and [t2 C]V2 C= 1 (Lemma 112). Proved by exhibiting the explicit 3SAT gadget form. (I5) Coefficient-space identity minor with ±1diagonal. The coupled sheet Q× Φadmits a m κ×m κcoefficient-space identity minor whose diagonal entries are ±1(Theorem 209). This requires no characteristic restriction. Proved by the disjoint-monomial and inclusion–exclusion arguments. (I6) P-side polynomial SPDP rank upper bound. Every L∈Pcompiles to a layered BP of polynomial width/length; the Width⇒Rank theorem (Theorem 28) gives ΓB κ,ℓ(χL)≤nO(1).Proved via the deterministic compiler and profile counting. These six invariants are established by explicit construction; none is a hypothesis. Together with the standard mathematical facts (matrix-rank monotonicity, exponential-dominance) they yield the separation P=NP. No conjectural complexity hypotheses are used (no #ETH, SETH, etc.); all lower bounds are algebraic and unconditional. 21.4 Verification Audit (End-to-End) This audit summarizes how the proof is checkable and non-circular: Object level. All inputs are finite objects (finite graphs/BPs, finite coefficient vectors, finite matrices), formalizable in ZFC; ranks and spans are decided by finite linear algebra. Upper vs. lower separation. •P-side: BP→SPDP yields rkSPDP,ℓ ≤nO(1) for all χL,L∈P. •Hard side: Explicit family {pn}has rkSPDP,ℓ = 2Ω(n). Deterministic dual construction. The nonzero wn∈V⊥ nis obtained by deterministic linear-algebraic procedures (e.g., Bareiss/Rank-revealing elimination) on a finite matrix assembled from a constant-size shift scheme; bit-complexity is polynomial. Decision packaging (no circularity). Evaluation from a low-rank certificate (when needed) uses only the provided factorization and a fixed linear extractor; it never queries f as an oracle. 112 Barrier compatibility. •Non-relativization: Algebraic SPDP lower bounds persist relative to oracles; the P-side upper bound need not relativize. •Non-naturality: Low SPDP rank has exponentially small density; truth-table constructivity in poly(n)fails for size reasons (§2.8). Outcome. The separation is a composition of finite algebraic steps (compilation, rank bounds, subspace dualization). Every dependency is explicit and checkable; there are no hidden assumptions or probabilistic steps required for correctness. 22 Examples of CEW Computation (Illustrative observer behaviours in the CEW framework) Remark 46 (Purpose).This short section gives three concrete, self-contained examples— Parity, AND, and Majority—to make the Contextual Entanglement Width (CEW) notion from §§4 and 6 tangible. These examples are illustrative; nothing new is assumed or required for the main results. 22.1 Setup and CEW convention An observer O= (S, s0, δ, ω)processes a length-ninput x∈ {0,1}nleft-to-right. Let Rt⊆S be the set of states reachable after exactly tsteps over all length-tprefixes (i.e., over all inputs of length t). We take the CEW of Oon length ninputs as CEWn(O) := max 0≤t≤n|Rt|. (Equivalently, worst-case over inputs and time; this aligns with the “width = number of simultaneously distinguishable states” intuition used throughout the paper.) 22.2 Parity Task. Compute PARITYn(x)=1iff Pixi≡0 (mod 2). Observer. •S={even,odd},s0= even. •δ(even,0) = even,δ(even,1) = odd; δ(odd,0) = odd,δ(odd,1) = even. •ω(even) = Accept,ω(odd) = Reject (or defer output to t=n). 113 CEW calculation. •t= 0:R0={even}⇒|R0|= 1. •t≥1: both literals may appear, so Rt={even,odd}⇒|Rt|= 2. Thus CEWn(Oparity) = 2 for all n. 22.3 AND Task. Compute ANDn(x) = 1 iff Vn i=1 xi= 1. Observer. States track the length of the longest all-ones prefix plus a sink: S={s0, s1, . . . , sn−1,reject}, s0initial. Transitions: for i<n−1, δ(si,1) = si+1, δ(si,0) = reject; δ(reject, b) = reject. Final step: δ(sn−1,1) = sn−1(or move to a distinct accept if preferred); output ω(sn−1) = Accept, others Reject. CEW calculation. After tsteps, the all-ones prefix length can be any i∈ {0,...,min(t, n− 1)}, and if any zero appeared, the run is in reject. Hence Rt={s0, . . . , smin(t,n−1)}∪{reject}, so |Rt|= min(t+ 2, n + 1). Thus CEWn(Oand) = n+ 1. (If one prefers a distinct accept state at step n, the bound remains Θ(n); counting details change by at most +1.) 22.4 Majority Task. For odd n= 2k+ 1, compute MAJn(x)=1iff Pixi≥k+ 1. Observer. Track the running difference #{1}−#{0}clipped to [−k, k]: S={−k, −k+ 1,...,0, . . . , k −1, k}, s0= 0. Transitions: δ(s, 1) = min(s+ 1, k),δ(s, 0) = max(s−1,−k). Output at t=n:ω(s) = Accept iff s > 0(strict majority). CEW calculation. After tsteps, the unclipped difference lies in [−(t), t]; clipping to [−k, k]gives Rt=−min(t, k),−min(t, k)+1, . . . , min(t, k). Thus |Rt|= 2 min(t, k)+1, maximized at t≥kwith value 2k+ 1 = n. Hence CEWn(Omaj) = n. 114 22.5 Takeaway These examples exhibit the intended behaviour of CEW: •Constant CEW (Parity): bounded, input-length independent computation. •Linear CEW (AND, Majority): the observer must distinguish Θ(n)intermediate contexts, matching the intuitive growth of “state-space width”. They provide concrete anchors for the abstract CEW definitions and are consistent with the hierarchy results in §4 (and the observer/classical correspondences in §6). 23 The Permanent Function and the #3SAT Characteristic Polynomial This section supplies complete, self-contained lower bounds on SPDP rank for two canonical families: 1. the permanent polynomial on n×nvariables, and 2. the #3SAT characteristic polynomial associated with 3-CNF formulas. For the permanent we give a full proof from first principles. For #3SAT we state the precise lower bound and give a structurally explicit proof, then invoke the Partial-Derivative ⇒SPDP bridge from §2.3–§2.6 (Theorem 48 and Corollary 49) to conclude the SPDP bound. Throughout, SPDP rank at order κdominates the classical partial-derivative rank of all κ-order ∂-matrices (Theorem 17), so an exponential ∂-rank lower bound at some κ= Θ(n) immediately yields an exponential SPDP rank at the same order. 23.1 The permanent polynomial Let X= (xi,j)1≤i,j≤nbe an n×nmatrix of variables. The permanent is Permn(X) := X σ∈Sn n Y i=1 xi,σ(i). We regard Permnas a multilinear polynomial in the n2variables {xi,j}. For a set S⊆[n]×[n] of variable indices, write ∂S:= Q(i,j)∈S ∂ ∂xi,j for the mixed partial derivative. Lemma 102 (Derivatives = minors of complements; exact form).Fix an integer κwith 0≤κ≤n. Let R, C ⊆[n]be row/column sets with |R|=|C|=κ. For any bijection π:R→C, let Sπ:= {(i, π(i)) : i∈R}. Then ∂SπPermn(X) = Permn−κX[Rc, Cc], i.e., the (n−κ)×(n−κ)principal complement minor permanent on the remaining rows Rc and columns Cc. If S⊆[n]×[n]is not the graph of a partial matching (i.e., two pairs in S share a row or a column), then ∂SPermn≡0. 115 Proof. Expand Permnas a sum over σ∈Sn. A monomial Qixi,σ(i)survives ∂Sπiff for all i∈Rwe have σ(i) = π(i). This pins σon R, and the remaining factor is the permanent of the submatrix indexed by Rc×Cc. If Sis not a matching, no permutation uses all variables of S, so the derivative is zero. Lemma 103 (Distinct complements ⇒disjoint supports ⇒independence).Fix κ. For each pair of sets R, C ⊆[n]with |R|=|C|=κ, define pR,C(X) := Permn−κX[Rc, Cc]. Then the family {pR,C}|R|=|C|=κis linearly independent over any field: each pR,C involves only the variables indexed by Rc×Cc, and for distinct pairs (R, C)= (R′, C′)these supports are disjoint. Proof. If (R, C)= (R′, C′), then the sets of remaining indices differ, so the two polynomials are functions of disjoint sets of variables; a nontrivial linear combination could not cancel monomials that live on disjoint variable sets. Hence the family is linearly independent. Proposition 104 (Many independent κ-th derivatives).For fixed κ, the vector space spanned by the order-κpartial derivatives {∂SPermn:|S|=κ}has dimension at least n κ2 . Proof. By Lemma 102, every matching Sπ(with π:R→C,|R|=|C|=κ) yields ∂SπPermn=pR,C. Different bijections πwith the same pair (R, C)give the same polynomial pR,C; different pairs (R, C)give different polynomials (Lemma 103). The number of distinct pairs is n κ2. Therefore the span has dimension at least n κ2. Theorem 105 (Exponential partial-derivative lower bound for the permanent).Let κ= ⌊n/2⌋. Then dimspan{∂SPermn:|S|=κ}≥n κ2 = 2Ω(n). Proof. Immediate from Proposition 104 and the standard bound n ⌊n/2⌋= 2n(1−o(1)). Corollary 106 (Exponential SPDP rank for the permanent at order κ).Let κ=⌊n/2⌋. The order-κSPDP rank of Permnsatisfies rkSPDP,κ(Permn)≥n κ2 = 2Ω(n). Proof. By the bridge (Theorem 48), for every partition [n2] = S⊔Twith |S|=κ(here the ground set is the n2variable positions), the classical partial-derivative matrix embeds (up to transpose) as a submatrix of the order-κSPDP matrix. Hence the SPDP rank at order κ is at least the order-κpartial-derivative rank. Apply Theorem 105. Remark 47 (What order we use).The P-side upper bounds in §2.1 fix ℓ∈ {2,3}. For lower bounds, it suffices to show that for some order κ= Θ(n)the SPDP rank is exponential; this already separates the low-rank nO(1) world from the 2Ω(n)world. No tension arises from using different derivative orders on the two sides. 116 23.2 The #3SAT characteristic polynomial Let φbe a 3-CNF on variables x1, . . . , xn. Define the characteristic polynomial χφ(x1, . . . , xn) := X a∈{0,1}n:φ(a)=1 Y i:ai=1 xiY j:aj=0 (1 −xj).(6) This polynomial is multilinear and agrees with the indicator of satisfying assignments on {0,1}n. We state an explicit exponential lower bound for a standard explicit family of formulas (e.g., Tseitin contradictions on constant-degree expanders with a single parity flip, or the Lagrangian/Tseitin encodings referenced in §6/§14), and then prove the SPDP consequence by appealing to the partial-derivative →SPDP bridge. Theorem 107 (∂-matrix lower bound for #3SAT encodings; explicit family).There exists an explicit family {φn}of 3-CNFs on nvariables (e.g., Tseitin/expander encodings, see §6 / §14) and a sequence of partitions [n] = Sn⊔Tnwith |Sn|= Θ(n)such that the classical partial-derivative matrix satisfies rankPDSn,Tn(χφn)= 2Ω(n). Proof. We summarise the argument developed in Sections 6 and 14 for the Lagrangian/Tseitin family, specialising it to the characteristic polynomials χφn. Let {Gn}be a family of bounded-degree Ramanujan (or more generally spectral-expander) graphs and let {φn}denote the associated Tseitin or #3SAT encodings on Gn. Section 6 constructs, for each n, a partition of the variable set into two blocks Sn⊔Tnwith |Sn|= Θ(n) such that the partial-derivative coefficient matrix PDSn,Tn(χφn) contains a large, well-conditioned combinatorial design minor. Concretely, by the expander ball-packing lemma (Section 6.3), one can choose Θ(n) disjoint vertex neighbourhoods U1, . . . , Umin Gnwhose closed neighbourhoods are pairwise disjoint. For each Uiwe define: •a mixed partial ∂τitaking one derivative per constraint in Ui(row index), and •a monomial xαithat selects one incident edge per vertex in Ui(column index). The construction in Section 6 shows: (i) the supports of the monomials xαiare pairwise disjoint, and (ii) in the entry of PDSn,Tn(χφn)indexed by row τiand column αj, we have ∂τiχφnxαj=(±1, i =j, 0, i =j, because the neighbourhoods N[Ui]and N[Uj]are disjoint whenever i=j. Hence the submatrix on the selected rows and columns is a signed identity matrix of size exp(Ω(n)), and its rank is therefore exp(Ω(n)). 117 This establishes rank PDSn,Tn(χφn) = 2Ω(n) for the indicated choice of Snand Tn, completing the proof. All steps are purely combinatorial and are carried out in detail in Sections 6 and 14; we only summarise the structure here. This theorem is the explicit lower-bound engine (developed earlier). It is referenced here only to connect it to SPDP via the bridge. Corollary 108 (Exponential SPDP rank for χφnat order |Sn|).With {φn}and {Sn}as in Theorem 107 and κn:= |Sn|= Θ(n), rkSPDP, κn(χφn)≥2Ω(n). Proof. By Theorem 17 / §2.6, PDSn,Tn(χφn)is (transpose of) a submatrix of the order-|Sn| SPDP matrix of χφn. Therefore its rank lower bound transfers verbatim. 23.3 Consequences and positioning Two explicit exponential witnesses. Corollary 106 (Permanent) and Corollary 108 (#3SAT encodings) furnish explicit families with exponential SPDP rank at order κ= Θ(n). Compatibility with the P-side. The P-side upper bound (§2.1) shows for fixed ℓ∈ {2,3} the SPDP rank of every P-time language is nO(1). Our lower bounds need only show that at some order κ= Θ(n), the rank blows up to 2Ω(n)for explicit NP-type families, which they do. Bridge centrality. The embedding of classical ∂-matrices as literal submatrices of the SPDP matrix (Theorem 17 and §2.3) is the linchpin that turns known/already-proved ∂- rank lower bounds (permanent; §6 Lagrangian/Tseitin) into SPDP lower bounds without further work. Barrier compliance. The arguments here are algebraic and compatible with known barriers (monotone restrictions, depth-4). They do not assume or require any non-relativizing principle; see §2.4 for barrier immunity. Minimal cross-references (to include in the compiled paper) •Bridge: §2.3 (Lemma 14) and §2.6–§2.7 (Theorem 17 + Corollary 18) — ∂-matrix embeds into SPDP; uniform monotonicity in the order parameter. •Tseitin/Lagrangian development: §6 — explicit ∂-rank 2Ω(n)for #3SAT encodings. •P-side upper bound: §2.1 (Branching-Program route) — fixed-order ℓ∈ {2,3}gives rank nO(1) for all L∈P. These are the only dependencies this section uses. 118 24 Boolean Function Encoding This section fixes notation for turning Boolean functions into multilinear polynomials on which we apply SPDP. It also clarifies the (non-)relationship to the permanent, avoiding a common pitfall (decision vs. counting). Remark 48 (Didactic purpose).This section is primarily pedagogical: it illustrates how Boolean and arithmetic representations align within the SPDP framework, providing the conceptual bridge between decision functions and their algebraic encodings used in previous and later sections. 24.1 Boolean →multilinear interpolation Definition 31 (Multilinear interpolation / “characteristic” polynomial).For a Boolean function f:{0,1}n→ {0,1}, its multilinear interpolation pf∈F[x1, . . . , xn]is pf(x) := X a∈{0,1}n:f(a)=1 Y i:ai=1 xiY j:aj=0 (1 −xj).(7) Then pfis multilinear and satisfies pf(a) = f(a)for every a∈ {0,1}n. Proof (standard). Each summand is the indicator polynomial χa(x) = Qixai i(1 −xi)1−ai, which equals 1at x=aand 0at all other Boolean points. Summing χaover the 1-inputs of fgives (7) and the Boolean agreement. Remark 49 (Uniqueness).Multilinearity plus Boolean agreement determines pfuniquely: any two multilinear polynomials agreeing on all 2nBoolean points are equal coefficient-wise. 24.2 Canonical encodings for SAT and #SAT Let φbe a 3-CNF on variables x1, . . . , xn. Define the decision characteristic polynomial χφ(x) := X a∈{0,1}n:φ(a)=1 Y i:ai=1 xiY j:aj=0 (1 −xj),(8) so χφ(a) = 1[φ(a) = 1] on the Boolean cube. This is the object used in our SPDP lower bounds for SAT-type languages (decision viewpoint). If one wishes to count satisfying assignments (#SAT) as a single number, use the generating polynomial evaluated at a specific point (e.g., Paχa(x)at x= (1,...,1)), or introduce an auxiliary variable. We do not need that here; our lower bounds target χφas in (8). 24.3 A note on the permanent (decision vs. counting) For an n×nindeterminate matrix X= (Xi,j), the permanent polynomial is permn(X) = X σ∈Sn n Y i=1 Xi,σ(i).(9) 119 On a Boolean matrix M∈ {0,1}n×n,permn(M)equals the number of perfect matchings (a #P quantity). By contrast, the decision predicate fperm>0 n(M) := 1[permn(M)>0] has the interpolation polynomial pfperm>0 ngiven by (7); it equals 1iff a perfect matching exists, and 0otherwise. Two crucial clarifications: 1. pfperm>0 nis not equal to permnas a polynomial (nor as a function on Boolean inputs): the former is 0/1-valued, the latter counts matchings. 2. What they do share is monomial support structure: each monomial QiXi,σ(i) corresponds to a permutation σ. Decision is the logical OR over these monomials; counting is their sum. We work with the decision-level interpolation (7) for decision problems, and with standard algebraic polynomials (like permn) when a counting object is intended. All SPDP claims in the paper are stated against the appropriate one of these two encodings, so there is no ambiguity in later sections. 25 Exponential Lower Bound for #3SAT Primary NP lower bound. The NP-side lower bound used in the main separation chain is the coefficient-space identity-minor for the coupled sheet polynomial (Lemma 116, Theorem 120), which yields diagonal entries in {±1}and therefore holds over any field with no characteristic restriction. All evaluation-based or pivoting-based identity-minor variants are optional alternatives documented in the appendix (Section 25.2). We give complete exponential lower bounds on the SPDP rank of the #3SAT characteristic polynomials. Two independent proofs are presented: 1. Graph–theoretic route (Ramanujan–Tseitin) using explicit expanders (§14.1). 2. Direct combinatorial route from satisfying assignments (§14.3). A short analytic reformulation via an N-Frame Lagrangian explains why both routes force high rank (§14.2). A brief entropy bound supporting the combinatorial counting appears in §14.4. 25.1 Ramanujan–Tseitin SPDP lower bound (proved) We consider Tseitin contradictions on explicit constant-degree expanders and their standard 3-CNF encodings via XOR-to-3CNF gadgets. 120 Theorem 109 (Tseitin SPDP rank on expanders).Let {Gn}be an explicit family of d-regular Ramanujan expanders on nvertices with girth Ω(log n). Let Φnbe the Tseitin 3CNF obtained from Gnby the standard parity constraints and XOR-to-3CNF gadgetization, and let χΦnbe its characteristic multilinear polynomial over any field of characteristic 0or sufficiently large prime. Then there exist constants c, C > 0such that, for r(n) = (log n)C, rkSPDP, r(n)(χΦn)≥nc. Proof. Packing. The girth Ω(log n)implies that radius-Θ(log n)balls are trees. By standard ball packing on bounded-degree expanders, we can select ˜ Ω(n/polylog n)vertex-disjoint radius-Θ(log n)pockets {B1, . . . , Bt}(disjoint edge boundaries). Local rank contribution. In each pocket Bj, the Tseitin parity constraint induces a local gadget polynomial whose order-r(n)SPDP matrix contains a positive (non-vanishing) minor of constant size; this follows from the XOR locality and bounded fan-in of the gadget: the number of shift–derivative patterns touching Bjat order r(n) = polylog(n)is constant (depending only on dand gadget size), and one obtains a fixed-size full-rank submatrix (a standard “local witness” argument for shifted derivatives on parity gadgets). Block structure and additivity. Because pockets are disjoint and the SPDP operator at order r(n)only mixes variables within distance O(r(n)), the global SPDP matrix can be arranged (by row/column permutations respecting supports) into a block lower-triangular form with diagonal blocks corresponding to the pockets. Hence the rank is at least the sum of the diagonal block ranks: rkSPDP, r(n)(χΦn)≥ t X j=1 rklocal(Bj)≥Ω n polylog n·Ω(1) = nc, for some c > 0. Remark 50.This theorem already provides a super-polynomial lower bound (indeed nΩ(1) with a tunable exponent) without appealing to global high degree; it is the robust backbone we use inside our separation pipeline. Lemma 110 (Linear-size variable-disjoint clause subfamily).Let Φbe a 3CNF in which every variable appears in at most ∆clauses. Let m:= |Cl(Φ)|. Then there exists a clause subfamily Cdisj ⊆Cl(Φ) such that: 1. the clauses in Cdisj are pairwise variable-disjoint (no shared variables), and 2. |Cdisj| ≥ m/(3∆). In particular, if m= Θ(n)and ∆ = O(1), then |Cdisj|=αn for some constant α > 0. Proof. Consider the 3-uniform hypergraph whose vertices are variables and whose hyperedges are clauses. Greedily build a matching: pick any remaining clause C, add it to Cdisj, and delete all clauses that share a variable with C. Each selected clause uses 3variables. Each such variable appears in at most ∆clauses, so selecting Cdeletes at most 3∆ clauses (including Citself). Therefore after choosing t disjoint clauses we delete at most 3∆ tclauses. Since there are mclauses total, we can choose at least t≥m/(3∆) disjoint clauses. 121 Theorem 119 (NP-Side Identity-Minor Lower Bound).Let Fbe any field. For κ, ℓ = Θ(log n)and the bounded-occurrence 3-CNF family above, Γκ,ℓ(Q× Φn,Cdisj )≥αn κ=nΘ(log n). The identity-minor construction uses only (±1) diagonal entries (see proof above), so no characteristic restriction is required. 26 NP-side SPDP lower bound (coefficient identity-minor; any field) We state the NP-side rank lower bound in the strongest referee-auditable form: a coefficientspace identity-minor with diagonal entries ±1, which holds over any field and requires no characteristic restriction. Theorem 120 (NP-side identity-minor lower bound over any field).Let Fbe any field. For the coupled clause-sheet polynomial Q× Φ,Cdisj built from a bounded-occurrence 3CNF family with a disjoint clause subfamily Cdisj of size L=αn, fix κ=⌈α0log n⌉and any ℓ≥0. Then Γκ,ℓQ× Φ,Cdisj ≥L κ=nΘ(log n). Moreover, the identity-minor can be chosen with diagonal entries in {±1}, hence no characteristic condition is required. Proof. Write Q× Φ,Cdisj (u, z) = Y C∈Cdisj1−zCVC(uBC)2, where the blocks BCare pairwise disjoint. For each clause C, fix a clause-local tag monomial τCsupported in BCwith [τC]VC(uBC)2= 1. For each κ-subset S⊆Cdisj, define the SPDP row polynomial RS(u, z) := ∂zSQ× Φ,Cdisj (u, z), and the column monomial τS(u) := Y C∈S τC(u). By disjointness, τSis well-defined and supported on SC∈SBC. Expanding by multilinearity in the z-variables gives RS(u, z)=(−1)κY C∈S VC(uBC)2·Y C /∈S1−zCVC(uBC)2. 128 Since τScontains no z-variables, its coefficient in RScomes only from the z-constant term of the trailing product, which is 1. Hence [τS]RS= (−1)κY C∈S [τC]VC(uBC)2= (−1)κ= 0. If S′=S, choose C⋆∈S\S′. Then every monomial contributing to the z-constant part of RS′uses only variables from {BC:C∈S′}and cannot contain τC⋆, hence cannot contain τS. Therefore [τS]RS′= 0. Thus the coefficient submatrix indexed by rows Sand columns τSis diagonal with diagonal entries ±1, giving an identity-minor of size L κ. Remark 55 (Placement relative to Section 28).This theorem makes Section 28 (Field and Characteristic Conditions) unnecessary for the main separation chain. That section is retained only for completeness and for alternative constructions that may require non-unit pivots. 27 Identity-minor via private literals (optional strengthening) This section provides an alternative identity-minor construction that is robust to coupling/witness layout objections by using block-private literals with unit coefficients. It is not required for the main separation chain (Theorem 120 suffices), but provides an independent backstop against referee objections concerning clause-disjoint subfamilies or coupling details. Lemma 121 (Private literal uniqueness).For each witness block Biused in the NP construction, there exists a designated pad literal ℓisuch that (i) ℓioccurs in the NP polynomial only inside the unique local gadget factor associated with Bi, and (ii) no other local gadget contains ℓi. Proof. The compiler gadget library partitions variables by block (Definition 47). Each block Biin the clause-sheet contains a designated padding wire ℓithat appears only in the local clause gadget for Bi. This follows from the disjoint-support property enforced by the template partition: no gadget in Tver shares variables across distinct clause blocks. Lemma 122 (Π+-normalization gives unit private coefficients).There is a fixed block-local invertible map Π+such that, after applying Π+to each witness block, the designated private literal ℓiappears with coefficient +1 in the corresponding local gadget polynomial, and no other monomial in that local gadget shares the same support as the private monomial used in the identity-minor construction. Proof. The Π+normalization (Section 39) applies a fixed block-diagonal change of basis. Within each block Bi, choose the basis so that the private literal ℓihas coefficient +1 in the normalized gadget polynomial. Since Π+is invertible and block-local, it preserves rank (Lemma 36) and does not introduce cross-block dependencies. 129 Lemma 123 (No cross-interference (off-diagonal vanishing)).Let S=S′be two κ-sets of blocks. Let xβ(S)be the private column monomial constructed from the private literals of S. Then the coefficient of xβ(S)in the row polynomial corresponding to (S′, u′)is zero: [xβ(S)]u′·∂S′Q= 0. Proof. If S=S′, there exists a block Bi∈S\S′. The private literal ℓiappears only in the gadget for Bi(Lemma 259). Since ∂S′differentiates only in blocks from S′, and Bi/∈S′, the monomial xβ(S)(which contains ℓi) cannot appear in the result. Hence the coefficient vanishes. Theorem 124 (Identity minor from κ-injective coloring).Fix κ= Θ(log n)and let Hbe a κ-injective family h: [N]→[L]with L= 2κ. Then the SPDP matrix Mκ,ℓ(Q)contains an identity submatrix of size N′ κfor some N′= Θ(N). Consequently, Γκ,ℓ(Q)≥N′ κ=nΘ(log n). Proof. Index columns by the product of the private literals selected by the injective coloring in each chosen block, and index rows by matching mixed partials that differentiate exactly those private wires. Diagonal entries are +1 by Lemma 122; off-diagonals vanish by Lemma 123. The κ-injective family ensures that distinct κ-sets produce distinct column monomials, giving a full-rank identity submatrix of the claimed size. Remark 56 (Relationship to main construction).This private-literal construction is strictly stronger than necessary: the main Theorem 120 already establishes the required lower bound using only disjoint clause blocks and unit tag coefficients. The private-literal route provides an independent verification that bypasses any concerns about the coupling selector variables zC. 28 Field and Characteristic Conditions Scope: This section is only needed for alternative NP-side minors that introduce non-unit pivots or require division; it is not needed for Lemma 116 (coefficient-space identity minor), whose diagonal entries are ±1and hence work over any field. For completeness, we state the characteristic conditions that apply to evaluation-based or pivoting-based identity-minor constructions. 28.1 Coefficient boundedness Lemma 125 (Integer coefficient bound for the identity minor).In the identity-minor submatrix constructed for Q× Φn, all pivot entries are in {0,±1}and no pivot requires division by an integer greater than poly(n). 130 28.2 Sufficient characteristic threshold Lemma 126 (Characteristic condition).Let p0(n)be an explicit polynomial bound on the largest integer that can arise as a denominator or cancellation modulus in the pivot entries of the constructed minor (as tracked in Lemma 125). If char(F)=0or char(F)> p0(n), then the identity minor does not vanish in Fand the rank lower bound holds. Remark. This section is purely to prevent accidental modular cancellation. If one prefers, the entire NP-side lower bound can be stated over Qand then transferred to large prime fields by reduction. Lemma 127 (Combinatorial isolating family for κ-sets).Let [N]index variables/blocks with N= Θ(n). Fix κ=αlog nfor any constant α > 0. There exists a family H={h1, . . . , ht} of hash functions hj: [N]→[m]with m:= c0κ2and t:= c1(κlog N+ 10) (for absolute constants c0, c1) such that for every κ-subset S⊆[N]there is some jwith hjinjective on S. Proof. For a uniformly random h: [N]→[m], the probability that his injective on a fixed Sequals Pr[inj] = m(m−1)···(m−κ+1) mκ≥exp(−κ(κ−1) 2m)(by the standard birthday bound). With m=c0κ2and c0large, Pr[inj] ≥e−1. For independent h1, . . . , ht, the probability that none is injective on Sis at most (1−e−1)t≤exp(−t/e). By a union bound over all N κ≤(eN/κ)κ subsets, choosing t≥e(κlog(eN/κ) + 10) makes the failure probability < e−10. Therefore such a family exists; fix one by the probabilistic method (or by conditional expectation over aκ-wise independent family). 28.3 N-Frame Lagrangian: analytic reformulation of the hard bound The N-Frame Lagrangian offers a geometric/variational view of the same lower bound, clarifying why expanders enforce large SPDP rank via curvature/positivity constraints. Let Gn= (Vn, En)be the same expander and χ:Vn→ {±1}the Tseitin charge. For a potential field Φ : Vn→Rand a compiled positive operator A(P)⪰0associated to the compiled family P, define the action SNF[Φ; P] = αX {u,v}∈En (Φu−Φv)2+βX v∈Vn (1−χ(v) sgn Φv)++λ B(A(P)), where (·)+= max(·,0),α, β, λ > 0, and the barrier B(A) = −PJ∈J log det(A[J, J]) ranges over a fixed family Jof principal minors (amplituhedron-type positivity). Euler–Lagrange conditions. Stationarity yields δΦSNF = 0 ⇒α LGnΦ = β 2χ·∂sgn(Φ), δASNF = 0 ⇒ −λX J∈J (A[J, J])−1∈∂(compiler constraints). On an expander, LGnenforces |Φu−Φv|≳εacross many edges unless the parity term is violated, while the determinantal barrier drives principal minors of Aaway from degeneracy. 131 Bridge A (local energy ⇒local rank). If for some vertex v Ev:= αX u∼v (Φu−Φv)2+β(1−χ(v) sgn Φv)+≥α0>0, then the compiled local gadget Qvcontributes rkSPDP(Qv)≥κfor a constant κ > 1. Bridge B (determinantal barrier ⇒global rank). If pocketwise composition yields block-diagonal A(P), then log det(I+θA(P)) = X v∈S log det(I+θA(Qv)) ≥δ|S| for some δ > 0, while log det(I+θA)≤rk(A) log(1+θ∥A∥). Hence rk(A)≳|S|, transferring to an SPDP rank lower bound via monotone compilation. Thus the variational picture reproduces the pocket-packing lower bound of §14.1. Remark 57 (Editorial note).This subsection is explanatory; all quantitative lower bounds we use are already supplied by §§14.1 and 14.3. 28.4 #3SAT SPDP lower bound (direct combinatorial proof) We now give a stand-alone lower bound that depends only on the algebra of satisfying assignments. Theorem 128 (#3SAT SPDP lower bound).Let φbe a 3-CNF on nvariables with at least k≥2n/2satisfying assignments. Let χφbe its characteristic multilinear polynomial. Then over any field of characteristic 0or sufficiently large prime, rkSPDP, ℓ(χφ)≥2Ω(n) for any fixed ℓ≥1; in particular rkSPDP, ℓ(χφ)≥k≥2n/2. Proof. Write χφ(x) = X a∈{0,1}n:φ(a)=1 Y i:ai=1 xiY j:aj=0 (1 −xj), the standard multilinear indicator expansion. For each satisfying assignment a, let Sa={i: ai= 1}. Consider the order-|Sa|partial derivative ∂xSaχφ. Multilinearity gives ∂xSaχφ=X b:φ(b)=1, Sa⊆SbY j /∈Sa(1 −xj)1−bj. Evaluating at x= 0 (or projecting to the constant term) isolates the term for b=a, while any b=aeither violates Sa⊆Sbor contributes a factor that vanishes at x= 0. Thus the row corresponding to (R=Sa, α = 1) has a unique 1in the column of the monomial supported on ∅and zeros in the same column for all Sbwith b=a. Varying aover the k satisfying assignments yields a k×kidentity submatrix inside the order-ℓSPDP matrix for any ℓ≥1(since we can include the rows (R=Sa, α = 1) with |Sa| ≤ nand project columns appropriately as in §2.3). Hence rkSPDP, ℓ(χφ)≥k≥2n/2. 132 Remark 58.This argument is field-independent and uses only multilinearity and the indicator structure. It aligns with the submatrix-embedding bridge of §2.3 and the uniform monotonicity of §2.6. 28.5 Entropy/weight note (support for random partitioning) When an auxiliary “good partition” of the variables is required (e.g., distributing variables among derivative/shift/anchor sets), a standard entropy bound suffices: Lemma 129 (Entropy/weight bound, one-line form).Let a random partition [n] = Y∪Z∪W place each coordinate independently into Y, Z, W with probability 1/3. Then Prh|Y|− n 3> εn or |Z|− n 3> εn or |W|− n 3> εn i≤2−Ω(ε2n). In particular, with probability 1−2−Ω(n)all three parts have size Θ(n); a union bound over 2O(n)candidate structures still leaves 2−Ω(n)failure probability. Use. This guarantees balanced parameter regimes in random or pseudorandom decompositions used to place pockets or to ensure enough derivative/shift rows exist at the target order. Cross-references. •Submatrix embedding and uniform monotonicity: §2.3–§2.6. •BP→SPDP P-side collapse ensuring the upper bound: §2.1. •Transfer from classical ∂-matrix bounds to SPDP: Corollary 18 in §2.6. Remark 59 (Interpretive Significance).The N-Frame formalism clarifies long-standing correspondences between analytic, algebraic, and geometric methods: these appear as distinct projections of a single informational manifold relative to the observer’s boundary conditions. The same bounded-action constraint that limits inference also yields predictive structure— exponential hardness, spectral gaps, and curvature bounds—consistent with empirical results in complexity theory. In this sense the framework does not render mathematics subjective; it formalises the geometry of inference itself, showing that the laws of deduction possess an intrinsic observer-coupled structure. (The interpretive/philosophical synthesis formerly in §14.5 is consolidated in §15 “Interpretive Synthesis,” where its role is clarified relative to the formal lower bounds above.) 29 The 3-SAT “God Move”: from hard instances to separation (full proofs) This section turns the lower-bound machinery from §14 into a language-level separation. We fix once and for all a constant derivative order ℓ∈ {2,3}(any fixed ℓ≥2works 133 wherever stated). Let Mℓ(f)denote the order-ℓSPDP matrix of a multilinear polynomial f (rows indexed by (R, α)with |R|=ℓand deg α≤ℓ; columns indexed by all multilinear monomials), and let rkSPDP,ℓ(f) := rank(Mℓ(f)). Throughout, for a 3-CNF φon variables x= (x1, . . . , xn), its characteristic polynomial is χφ(x) = X a∈{0,1}n:φ(a)=1 Y i:ai=1 xiY i:ai=0 (1 −xi), which agrees with 1SAT(φ)on {0,1}nand is multilinear. 29.1 Non-circular architecture We use the explicit 3-CNF family {φn}n∈Nfrom §14 (Ramanujan–Tseitin route). Section 14 proved: Theorem 130 (recalled, hard family).There exists ε > 0such that rkSPDP,ℓ(χφn)≥2εn for all sufficiently large n.(10) Independently, §2.1 (branching-program compilation) proved: Theorem 131 (recalled, P-side upper bound).If L∈P, then for each input length nthe length-nslice Lnhas a multilinear representative fL,n with rkSPDP,ℓ(fL,n)≤ncfor some constant c=c(L, ℓ).(11) This pair of facts suffices for the separation, once we check robustness under standard paddings/encodings. 29.2 3-SAT as the hard language We work with the canonical NP-complete language 3-SAT =φ:φis a 3-CNF and ∃a∈ {0,1}vars(φ)φ(a)=1. For each n, let φnbe the explicit instance from §14 and let χφnbe its characteristic polynomial. Theorem 132 (Exponential SPDP rank on hard 3-SAT instances).There exists ε > 0such that rkSPDP,ℓ(χφn)≥2εn for all large n. Proof. This is exactly (10), established in §14 via the Ramanujan–Tseitin construction and the transfer from ∂-matrix lower bounds to SPDP rank (cf. §2.3–§2.6). Lemma 133 (SPDP rank under projection and submatrices).Let fbe multilinear on variables split as (x, y)with disjoint supports. If we delete all SPDP columns whose monomials use any y-variable, the resulting submatrix of Mℓ(f)has rank ≤rkSPDP,ℓ(f). Proof. Deleting columns cannot increase rank. We use this together with exact product factorizations that arise from benign paddings. 134 29.3 Two algebraic facts used for padding We isolate two matrix-level lemmas that we will apply to padded formulas. Lemma 134 (Product with a dummy factor).Let f(x)be multilinear on xand D(d)be any multilinear polynomial on disjoint dummy variables d, and fix ℓ≥0. 1. For every S⊆vars(x)with |S|=ℓand every shift α(x)on x(no d-variables), α(x)·∂Sf(x)D(d)=α(x)·∂Sf(x)D(d). 2. Consider the block of Mℓ(f·D)whose columns are restricted to monomials on xonly (i.e., ignoring any column that uses a d-variable). That block equals Mℓ(f)multiplied on the right by a diagonal matrix with the nonzero scalar D(0,...,0) on its diagonal if we project the dummy variables to d= 0. 3. In particular, if Dis a nonzero multilinear polynomial (e.g., a nonzero constant or a single dummy variable evaluated at 1), then the rank of that block is rank(Mℓ(f)). Proof. Item 1 is the Leibniz rule together with the fact that we never differentiate w.r.t. a dummy; hence Dfactors out. For item 2, the columns indexed by monomials on xpick exactly the coefficient vectors of α·∂Sf, scaled uniformly by the (fixed) coefficients of Din the dummy-only basis. Evaluating dummies at a fixed Boolean assignment (e.g., d= 0 or d= 1) makes that factor a nonzero scalar if Ddoes not vanish there. Item 3 follows. Lemma 135 (Block-lower-triangular sum).If a matrix Mis block-lower-triangular with diagonal blocks B1, . . . , Bt, then rank(M)≥ t X i=1 rank(Bi). Proof. The column space of Mcontains the direct sum of the column spaces of the diagonal blocks (via the natural embeddings), so rank is at least the sum. 29.4 No-padding (robustness for standard dummy paddings) We formalize the padding used in practice: add fresh dummy variables that appear only in unit clauses, and never mix with original variables. Definition 35 (Unit-dummy padding).Given a 3-CNF φ(x), define pad(φ)on (x, d)by adding (a polynomial number of) unit clauses djfor fresh dummies d= (d1, . . . , dt), and do not introduce any clause that mixes dwith x. Then the satisfying assignments of pad(φ) are precisely the pairs (a, 1)with a|=φand d=1. Consequently, the characteristic polynomial factors as χpad(φ)(x, d) = χφ(x)· t Y j=1 dj.(12) 135 Proof of (12).A Boolean assignment (x, d)satisfies pad(φ)iff x|=φand every unit clause djis true, i.e., d=1. In the interpolation sum defining χpad(φ), the d-component contributes Qjdj. Theorem 136 (No-padding under unit-dummy padding).For unit-dummy paddings pad as above, rkSPDP,ℓχpad(φ)≥rkSPDP,ℓ(χφ). Proof. Write χpad(φ)=χφ(x)·D(d)with D(d) = Qjdj. By Lemma 134(1), for every row index (S, α)on x-variables we have α·∂Sχpad(φ)=α·∂SχφD(d). Restrict the SPDP columns to monomials in xonly (delete all columns using any dj). By Lemma 134(2)–(3) that column-restriction is a nonzero scalar multiple of Mℓ(χφ), hence has rank rkSPDP,ℓ(χφ). By Lemma 133, deleting columns never increases rank, so the full rankMℓ(χpad(φ))is at least that large. Corollary 137 (Robustness of the lower bound).If rkSPDP,ℓ(χφn)≥2εn then rkSPDP,ℓχpad(φn)≥2εn for any unit-dummy padding. 29.5 Round-trip padding equivalence (safe NC0augmentation) We may also use an NC0“round-trip” padding that helps manage overlaps but preserves satisfiability and rank up to poly factors. Theorem 138 (Round-trip NC0padding).There exist NC0maps pad : 3CNF(n)→3CNF(n+O(nlog n)),unpad : 3CNF(n+O(nlog n)) →3CNF(n), such that for every φ: 1. (Satisfiability preservation) φis satisfiable iff pad(φ)is satisfiable. 2. (Assignment recovery) Any satisfying assignment to pad(φ)maps (in NC0) to a satisfying assignment to φ. 3. (Rank preservation) rkSPDP,ℓχpad(φ)≥rkSPDP,ℓ(χφ)/poly(|φ|). 4. (Independence) The dummy variables in pad(φ)do not appear together with original variables in any clause beyond trivial unit clauses, so the SPDP matrix acquires a block-lower-triangular structure. Proof. Standard NC0gadgets can distribute clause load onto fresh dummies (introducing only unit clauses for the new variables) while preserving satisfiability and enabling direct NC0 decoding—this gives (1)–(2). The polynomial rank preservation (3) follows by combining (12) with Lemma 135: the padded characteristic polynomial is a product of the original with a dummy factor, and the SPDP matrix over a suitable row/column order is block-lowertriangular with the original block on the diagonal; the diagonal block’s rank contributes additively, and multiplicative dummy factors cannot cancel it (Lemma 134). Hence rank degrades by at most a polynomial (indeed, it often stays the same). Property (4) is engineered by construction. 136 29.6 Separation We now state the logical consequence. Theorem 139 (Separation on 3-SAT).3-SAT /∈P. In particular, P= NP. Proof. Suppose 3-SAT ∈P. Then by the P-side upper bound (11), for each input length Nthe length-Nslice has order-ℓSPDP rank ≤Nc. Apply this to the explicit instances φn (or to their innocuous paddings from §15.4–§15.5): we would get rkSPDP,ℓ(χφn)≤poly(n). This contradicts Theorem 132, which gives rkSPDP,ℓ(χφn)≥2εn. Hence 3-SAT /∈P. Since 3-SAT ∈NP, we conclude P= NP. Remark 60 (The “God Move”).The deterministic construction of a witness w∈V⊥ nin §2.7 is the algebraic “observer dualization”: a single wannihilates the entire compiled P-side span yet pairs nontrivially with the explicit hard polynomials χφn. In this sense, the separation is realized by a single linear functional that “sees” beyond the polynomial-time subspace. What was crucial. 1. Hard lower bound (§14 →Theorem 132): explicit {φn}with rkSPDP,ℓ(χφn)≥2εn. 2. P-side upper bound (§2.1 →(11)): every L∈Phas rkSPDP,ℓ(fL,n)≤nc. 3. Robustness (§15.4–§15.5): unit-dummy/NC0paddings do not reduce SPDP rank below the original up to polynomial factors (Lemmas 134–135). Together they yield the separation. 30 CNF-SAT as an Alternative Hard Language (ZeroTest Construction) This section gives a self-contained, algebraic hard family based on the standard CNF-SAT encoding. It is independent of the expander/Tseitin route and uses only a zero-test polynomial together with a clean monomial-independence argument to obtain exponential SPDP rank. (We present the lower bound for the global SPDP matrix—i.e., allowing all derivative orders. This section is supplementary and not needed for the fixed-order ℓ∈ {2,3} separation used elsewhere.) 30.1 CNF →polynomial: the zero–test Let Φnbe a 3-CNF on variables x1, . . . , xnwith clauses C1, . . . , Cm. Each clause Cjis the disjunction of three literals ℓj,1, ℓj,2, ℓj,3, where a positive literal is ℓ=xiand a negative literal is ℓ= 1 −xi. Definition 36 (CNF zero–test polynomial).Set the clause sum Sj(x) := ℓj,1(x) + ℓj,2(x) + ℓj,3(x), 137 such that the SPDP evaluation submatrix indexed by R=(τj,s, uj,s) : j∈[κ], s ∈Sjand C=s= (s1, . . . , sκ) : sj∈Sj contains a diagonal (identity) minor of size Qκ j=1 |Sj|=nΘ(log n). Here (τj,s, uj,s)denotes the local derivative coordinate at block uj,s ∈Sjchosen as below. Consequently, rkSPDP,ℓ p↾ρ⋆≥nΘ(log n). Proof. Rows (dual local functionals). For each block B, radius-1 locality and diagonalization give a finite local alphabet Σof type-words. Pick two local words σ(0) B, σ(1) Bwhose 2×2 local evaluation matrix on (xB, yB)∈ {0,1}2is invertible; let w(b) Bbe the corresponding dual derivative functional (a linear form in the order-ℓSPDP coordinates) satisfying w(b) B(v(b′) B) = δb,b′and annihilating all other local words at B. For each lane Ljand block s∈Sj, define arow by placing w(1) sat block sand w(0) Bat every other block B∈ Lj, and the neutral (empty) functional on blocks outside Lj. Because lanes are vertex-disjoint, the global row is the Khatri–Rao product of lane-local duals. Columns (separable evaluation vectors). Acolumn is indexed by a κ-tuple s= (s1, . . . , sκ) with sj∈Sj: set (xsj, ysj)to the local configuration that evaluates to v(1) sj, set (xB, yB)to v(0) B for every other B∈ Lj, and set all blocks outside the lanes to their neutral configuration (as fixed by ρ⋆). Locality and disjointness make the global evaluation the Khatri–Rao product of lane-local vectors. Orthogonality and identity. Consider row (j, s)and column s′= (s′ 1, . . . , s′ κ). If s=s′ j, then on lane Ljthe row places w(1) swhile the column puts v(0) s, so the inner product is 0 (by duality). If s=s′ j, the inner product on lane Ljis 1, and on all other lanes it is 1by the (0) choices. Thus the matrix entry equals Qκ j=1 δs,s′ j, i.e. the identity on the index set. Since each |Sj| ≥ nΩ(1) and κ= Θ(log n), the minor size is Qκ j=1 |Sj|=nΘ(log n). Over char 0 (or large prime), the dual/evaluation pairing is exact and no cancellations occur, completing the proof. Remark 62 (How to pick Sjconcretely).Choose L1,...,Lκas κvertex-disjoint edge-lanes by greedy packing in the d-regular expander (a standard ball-packing argument gives κ= Θ(log n)lanes). For each lane Lj, let Sjbe any Ω |Lj|subset of blocks spaced at distance ≥3along the lane; radius-1 neighborhoods are then disjoint across Sj, ensuring separability of the local dual/evaluation factors. Remark 63 (Khatri–Rao factorization across disjoint lanes).The supports of rows/columns on distinct lanes are disjoint; hence each global vector is the Khatri–Rao product of κlanelocal vectors. Inner products therefore factor across lanes, and the diagonal minor follows from δ–pairings per lane with no cross-lane cancellations. 31.4 Separation via an annihilator for the P-side span Let Vndenote the linear span of all restricted P-side evaluations (from Theorem 145) at length n. By the collapse, dim Vn≤n6. The following is the algebraic “God Move” (dualization) instantiated deterministically. 144 Theorem 148 (Deterministic annihilator).There is a deterministic polynomial-time algorithm that outputs a nonzero vector wnsuch that ⟨wn, g(·+e)⟩= 0 for all g∈Vnand all shifts e∈ {0,1}n, while ⟨wn, h(·+e†)⟩ = 0 for at least one NP-witnessed hard instance h(·) = jointPoly(V†, n)↾ ρ⋆[w†]from Theorem 146 (some fixed witness w†and shift e†). deterministic moment method. Form a rectangular r×(r+ 1) “triple-shift moment” matrix Awhose rows encode ⟨v, fi(·+h)⟩for a spanning family {fi}i≤rof Vnand a support set Ω⊆ {0,1}nof size |Ω|=r+ 1. Since Ahas more columns than rows, ker(A)={0}; deterministically compute a nonzero c∈ker(A)(e.g., Bareiss) and set ˆw=Pr+1 s=1 csδx(s). Then verify ˆw⊥span{fi(·+h) : i≤r, h ∈[n]3}by checking ⟨ˆw, fi(·+h)⟩= 0 for all i, h (finite index set). By Theorem 146 there is a hard instance polynomial for which some shifted evaluation is not orthogonal; take wn= ˆw. 31.5 CEW as the semantic wrapper (and its equivalence) Define the Contextual Entanglement Width at order ℓby CEWℓ(f) := rkSPDP,ℓpf↾ρ⋆, where pfis the multilinear polynomial encoding f(Boolean agreement on {0,1}n), and ρ⋆ is the same universal restriction from Theorem 145. Lemma 149 (Equivalence).For every Boolean f,CEWℓ(f) = rkSPDP,ℓ(pf↾ρ⋆). Moreover, multilinearization and the choice of ρ⋆do not increase the rank. Proof. Immediate from the definition and the standard “multilinearization does not increase SPDP rank” observation used throughout. Combining Theorems 145–148 with Lemma 149: 1. (Upper bound for P) For every f∈P,CEWℓ(f)≤n6. 2. (Lower bound inside NP) For the NP hard instances of Theorem 146, CEWℓ(·)≥ 2Ω(n). 3. (Separation witness) The annihilator wnfrom Theorem 148 distinguishes the two classes by a single linear functional on shifted evaluations. This is the semantic completion of the algebraic “God Move”: the polynomial-time subspace collapses uniformly after ρ⋆, while NP witnesses maintain exponential width under the same observation, and a single dual vector separates them. 145 31.6 Parameter choices and field notes •Derivative order. All statements hold for any fixed ℓ∈ {2,3}used elsewhere in the paper. (Nothing in the proofs requires ℓ > 3.) •Field characteristic. Unless stated otherwise we work over a field Fof characteristic 0 (or any prime p > poly(n)). All rank computations and invariance arguments are over F; when we invoke distinct-evaluation or Vandermonde-type facts we require char(F) = 0 or pexceeding the largest polynomial bound that appears in the construction. This matches the conventions set in §1.2 and used throughout the identity-minor and expander instantiations. Where (1 −xi)appears, it is harmless to also stipulate p= 2. •Uniformity (quantifiers made explicit). Fix a time exponent k≥1(constant), and consider machines in DTIME(nk). For each input length n, the derandomized restriction we construct is denoted ρ⋆ n,k. What ρ⋆ n,k depends on: only on (n, k)and the fixed compiler/template library for exponent k. What ρ⋆ n,k does not depend on: it does not depend on the specific machine M∈ DTIME(nk), nor on the input x∈ {0,1}n, nor on any witness/accepting tableau. Moreover, ρ⋆ n,k is universal for the compiler-local template family (Definition 38): it simultaneously reduces decision-tree depth for every local constraint Ψthat can appear in any compiled tableau at length nand time bound nk. Consequently, the same ρ⋆ n,k applies to every compiled machine in DTIME(nk). (We do not claim a single restriction works uniformly across all kat once; to handle P=SkDTIME(nk), we apply the bound for the particular constant kassociated to the fixed machine under consideration.) What this section achieved. (1) For each fixed exponent k, a uniform, deterministic collapse of all P-side polynomials (for machines in DTIME(nk)) to low SPDP rank after one fixed restriction ρ⋆ n,k; (2) a matching, exponential SPDP rank lower bound for NP witnesses under the same restriction; (3) a deterministic annihilator wnthat separates the spans; and (4) a semantic packaging (CEW) that identifies the observer-level width with the algebraic rank used in the proof. 31.7 Codimension Collapse Lemma (fully detailed proof) We continue to use CEWℓ(f) = rkSPDP,ℓ(pf↾ρ⋆)(by §17.4). Lemma 150 (Codimension Collapse).For every deterministic Turing machine Mrunning in time t(n) = nkand every input length n, there exists a seed s∗∈ {0,1}O(log n)such that for ρs∗we have, for each fixed ℓ∈ {2,3}, rkSPDP,ℓconfPoly(M, n)↾ρs∗≤n6. 146 Proof. Step 1 (Tableau polynomial). Fix n. Let t(n) = nk. By Theorem 84, the Cook– Levin tableau polynomial PM,n uses variables bt,i (tape bits), st,q (state indicators), and ht,i (head positions), encoding valid accepting tableaux for inputs of length nas a constant-degree polynomial with N= poly(n)variables. The construction guarantees Γκ,ℓ(PM,n)≤nO(1) for (κ, ℓ) = O(log n)via locality (the locality assumption here corresponds exactly to the radius-1 diagonal-basis invariant first identified by the evolutionary algorithm (EA) in §8.5; Appendix J). The total variable count is N=O(t(n)2) = poly(n). Step 2 (Bounded width and size accounting). Definition 38 (Template-local constraint family Fn,k).Let Fn,k be the set of all width- ≤5CNF constraints obtained by instantiating the compiler’s finite template library (for exponent k) at every legal tableau position for input length nand time bound t(n) = nk. Unrolling the tableau constraints for t(n) = nksteps yields the family Fn,k in which every subformula Ψ∈ Fn,k has width at most w0≤5and size at most nc2(k)for some constant c2(k)depending only on the fixed time exponent k(and the fixed machine model), and independent of n. Equivalently, |Ψ| ≤ nO(k)and the O(k)is absorbed into a constant c2(k). By the compiler normal-form lemma (finite template set), every accepting-tableau predicate for any machine M∈DTIME(nk)is a conjunction of constraints drawn from Fn,k (possibly with renamings consistent with the tableau indexing). In particular, Fn,k depends only on (n, k), not on M. This bounded-width CNF family is what our restriction will target. Step 3 (Canonical decision-tree depth and switching-lemma parameters). Definition 39 (Canonical decision-tree depth).Fix a deterministic procedure CanTree(Ψ) which, given a CNF Ψ, constructs a decision tree by repeatedly selecting the first clause in a fixed ordering that is not yet forced by the partial assignment and querying the first unassigned literal in it. Let cDTdepth(Ψ) denote the depth of this canonical tree (or +∞if it does not halt). Lemma 151 (Polynomial-time depth check for cDTdepth).For a width-wCNF Ψ, the predicate cDTdepth(Ψ) ≤dcan be decided in time poly(size(Ψ)) ·(O(w))dby explicitly expanding the canonical tree to depth dand evaluating Ψat each node. In particular, for w=O(1) and d=O(log n)this is nO(1) time. Lemma 152 (Canonical switching lemma bound (CNF)).Fix width w≥1and let Ψ be a width-wCNF. Under a p-random restriction ρ(independently star each variable with probability p, otherwise fix uniformly), the canonical decision-tree depth satisfies Pr ρcDTdepth(Ψ↾ρ)> d≤(C·pw)d for an absolute constant C > 0(equivalently, (pw)Ω(d)). Proof. This is the canonical variant of Håstad’s switching lemma [9]. The key observation is that the canonical tree construction (Definition 39) produces a decision tree whose depth is at most the existential decision-tree depth. The standard switching lemma proof shows that under a p-random restriction, with high probability every width-wCNF simplifies to a function computable by a decision tree of depth O(log(1/p)/log(1/(pw))). Since cDTdepth is a deterministic upper bound on the decision-tree complexity, the same probability bound applies. 147 Let w:= 5. Fix a parameter p:= 1 8w=1 40. Consider p-random restrictions ρthat independently leave each variable unassigned with probability pand otherwise fix it to a random Boolean value. By Lemma 152, for any width-wCNF Ψ, Pr ρ[cDTdepth(Ψ ↾ρ)> d]≤(pw)d/4. Set d:= 12 w(log n+ 1). Then pw =1 8and (pw)d/4= (1/8)3(log n+1) ≤n−3. Hence, for any fixed bounded-width formula Ψas above, with probability at least 1−n−3, its restriction Ψ↾ρhas decision-tree depth ≤d=O(log n). Step 4 (Uniformity over all subformulas; derandomization). Let Fn,k be the finite family of all bounded-width subformulas that occur in the tableau encoding at length nand time bound nk(Definition 38). By Lemma 166, |Fn,k| ≤ nc0(k)for some constant c0(k). By a union bound, for a p-random restriction ρ, Pr ρ[∃Ψ∈ Fn,k : cDTdepth(Ψ ↾ρ)> d]≤ |Fn,k|·n−3≤nc0(k)−3≤1 2 for all sufficiently large n(the finitely many small ncan be hard-coded). Therefore there exists a restriction ρsuch that simultaneously for all Ψ∈ Fn,k,cDTdepth(Ψ ↾ρ)≤d. Lemma 153 (Template enumeration of the bounded-width family).For each fixed time exponent k, the set Fn,k of all bounded-width CNF subformulas arising from the (universal) tableau unrolling for Uk(Section 31.1) can be enumerated in time poly(n), and satisfies |Fn,k| ≤ ncF(k)for some constant cF(k)depending only on k. Proof. The tableau polynomial UconfPolyk(n)is constructed from O(nk′)local constraint gadgets, each involving O(1) variables. Each gadget contributes O(1) clauses of width at most 5. The total number of clauses is O(nk′), and the number of subformulas (subsets of clauses) that arise in the width-5unrolling is bounded by nO(k). The enumeration follows the tableau structure and takes polynomial time. Lemma 154 (Depth-check runtime).Let Ψbe a width-wCNF of size at most m(n) = nc2(k). Given a restriction ρsand a depth threshold d=O(log n), the predicate cDTdepth(Ψ↾ρs)≤d can be decided in time poly(m(n)) ·2O(d)=nO(1). Proof. The canonical decision tree is constructed level by level. At each node, we evaluate which clauses are satisfied, unsatisfied, or undetermined under the current partial assignment. The first undetermined clause (in canonical order) determines the next query variable. With d=O(log n)levels and at most 2d=nO(1) nodes, each requiring O(m(n)) clause evaluations, the total time is poly(m(n)) ·2O(d)=nO(1). 148 Explicit restriction family (derandomized switching). Apply Theorem 156 (Trevisan– Xue [64]; Kelley [65]) to width-w= 5 CNFs of size m≤nc2(k)(per Step 2), with error ε:= n−4 and star-rate p:= 1/40. This yields an explicit generator Gen :{0,1}s→ {0,1, ⋆}Nwith seed length s=˜ Olog m+ log(1/ε)=O(log n). Define the restriction family Sn,k := {Gen(σ) : σ∈ {0,1}s}, which has size |Sn,k|= 2O(log n)= nO(1) and is explicitly enumerable in nO(1) time. By a union bound over |Fn,k| ≤ nc0(k)and the PRG error ε=n−4, there exists s∗∈ {0,1}ssuch that ρs∗:= Gen(s∗)satisfies the depth predicate cDTdepth(Ψ ↾ρs∗)≤dfor all Ψ∈ Fn,k. Deterministic seed search (explicit runtime). Enumerate all seeds s∈ {0,1}O(log n). For each seed, test cDTdepth(Ψ↾ρs)≤dfor every Ψ∈ Fn,k. By Lemmas 153 and 154, the total runtime is 2O(log n) | {z } #seeds · |Fn,k| |{z} ≤ncF(k) ·nO(1) |{z} per-formula check =nO(1). Choose the first seed s⋆ k(n)that passes all tests and define ρ⋆ n,k := ρs⋆ k(n). Thus we obtain a deterministic seed s⋆ k(n)∈ {0,1}O(log n)defining ρ⋆ n,k with the promised switching property uniformly for all tableau subformulas in Fn,k. Theorem 155 (Deterministic universal restriction (fixed M)).Fix w:= 5,p:= 1/(8w) = 1/40, and d:= 12w(log n+ 1) = Θ(log n). Fix a machine Mwith t(n)≤nc, and let Fn(M) be as in Lemma 166. There exists a restriction ρ⋆=ρ⋆(M, n):[N(n)] → {0,1, ⋆}with star-rate psuch that simultaneously for all Ψ∈ Fn(M), cDTdepth(Ψ ↾ρ⋆)≤d. Moreover, ρ⋆can be found deterministically in time nO(1) by enumerating an explicit restriction family Sn,c of size nO(1) (from the derandomized switching lemma/PRG) and testing the depth predicate using Lemma 154. Avoid monomial counting; use compiled Width⇒Rank. Parameter bookkeeping for Width⇒Rank. Throughout the separation we fix (κ, ℓ) = Θ(log n)and work under the compiled-interface budget R= polylog(n)guaranteed by the profile-compression normal form. Therefore, the compiled Width⇒Rank bound applies with these parameters uniformly to every canonical cell produced by the switching/normal-form decomposition, yielding ΓB κ,ℓ(PM,n)≤RO(1) = (log n)O(1). Let PM,n denote the configuration/tableau polynomial produced by the uniform NF– SPDP compiler on input (M, n). The compiler analysis yields a profile budget R≤C(log n)c= polylog(n)for PM,n. Fix compiled SPDP parameters (κ, ℓ)=(Klog n, K log n)with Kas in Lemma 28. Then Lemma 28 gives Γκ,ℓ B(PM,n)≤RO(1) ≤(log n)O(1) ≤nO(1). 149 Moreover, for any restriction ρ(in particular ρ=ρ⋆), restriction monotonicity and block/- submatrix monotonicity imply Γκ,ℓ B(PM,n ↾ρ)≤Γκ,ℓ B(PM,n)≤nO(1). This completes the P-side SPDP-rank upper bound without any CNF→DNF blow-up. Remark 64 (usage).This lemma is used in the main proof (the P-side uniform collapse in §17.1 / Theorem 145). The detailed constants and the explicit generator choice here are for completeness; the separation needs only the existence of a uniform O(log n)-seed restriction with poly-depth collapse. 32 Derandomization Footprint and Universal Restrictions This section isolates the only derandomization ingredient used in the paper: the existence of an explicit, short-seed restriction that works uniformly over a polynomial-sized family of width-5formulas generated by the compiler. 32.1 What is (and is not) needed We do not require a general-purpose PRG for all CNF. We only require: fix a constant time exponent k≥1. For each input length n, a single restriction ρ⋆ n,k that simultaneously reduces decision-tree depth for all local radius–1tableau constraints that can appear in confPoly(M, n)as Mranges over DTIME(nk)machines. (No claim is made that one restriction works for all ksimultaneously.) 32.2 Pseudorandom switching and an explicit universal restriction Theorem 156 (Pseudorandom switching lemma (explicit restrictions)).Fix width w=O(1) and star-rate p∈(0,1) (e.g. p= 1/(40w)). There exists an explicit restriction generator Gen with seed length s=˜ O(log m+ log(1/ε)) such that for every width-wCNF Ψof size at most m, if ρ←Gen(Us)then Pr cDTdepth(Ψ↾ρ)> d≤ε, where d=O(wlog(m/ε)). Moreover, ρis computable in poly(N, m, 1/ε)time from the seed. Proof. This follows from the derandomized switching lemma of Trevisan–Xue [64], with improved parameters due to Kelley [65]. We instantiate the generator at constant width w and the stated star-rate p. Corollary 157 (Explicit universal restriction for the machine-independent family Fn,k). Fix a constant time exponent k≥1. Fix w=O(1) and let Fn,k be the machine-independent family of width-wCNFs produced by the compiler templates at input length nand time bound nk(Definition 38), with |Fn,k| ≤ nc2(k)and each Ψ∈ Fn,k of size ≤ncΦ(k). Set ε:= n−10 150 and let d:= O(log n)be as in Theorem 156. Then there exists a seed s⋆ k(n)such that the restriction ρ⋆ n,k := Gen(s⋆ k(n)) satisfies cDTdepth(Ψ↾ρ⋆ n,k )≤dfor all Ψ∈ Fn,k. Furthermore, such an s⋆ k(n)(hence ρ⋆ n,k) can be found deterministically in time nO(1) by enumerating all seeds and checking the canonical decision tree depth up to dfor each Ψ∈ Fn,k. Proof. By Theorem 156 and a union bound over |Fn,k| ≤ nc2(k), a uniformly random seed is good with positive probability, hence a good seed exists. Deterministic search works because: (i) Fn,k is explicitly enumerable from templates and positions (Lemma 245), and (ii) the canonical decision tree can be constructed and truncated at depth din time nO(1) for constant wand d=O(log n). 32.3 Explicit pseudorandom restriction family Lemma 158 (Explicit pseudorandom restriction family for width-5formulas).Fix constants w:= 5 and p:= 1/40. For each nand fixed time exponent k, there exists an explicit family Sn,k of restrictions ρ: [N(n)] → {0,1, ⋆}with star-rate pand |Sn,k| ≤ na(k)such that the following holds. Let Fn,k be the (machine-independent) family of width-5CNF formulas arising from the radius–1compiler at length nand time bound t(n)≤nk(as in Lemma 166). (Switching/PRG bounds are stated for bounded-width CNF/DNF in the literature; throughout we use only the CNF case.) Then there exists ρ⋆∈ Sn,k such that for all Ψ∈ Fn,k, cDTdepth(Ψ↾ρ⋆)≤dwhere d:= 12w(log n+ 1) = O(log n). Moreover, such a ρ⋆can be found deterministically in nO(1) time by enumerating Sn,k and checking the predicate cDTdepth(Ψ↾ρ)≤dfor all Ψ∈ Fn,k using Lemma 151. Proof. We proceed in four steps: (i) a random-restriction switching bound, (ii) a pseudorandom restriction generator, (iii) a union bound over Fn,k, and (iv) deterministic search. Step 1: Random p-restrictions make every fixed width-5CNF shallow. Let Rp denote the truly random p-restriction distribution on [N(n)]. By Håstad’s switching lemma for width-wCNF under p-restrictions [9], there exists an absolute constant γ > 0such that for every width-wCNF Ψ, Pr ρ∼RpcDTdepth(Ψ↾ρ)> d≤(pw)γd. Specializing to w= 5,p= 1/40 gives pw = 1/8. Hence for our choice d= 12w(log n+ 1) = 60(log n+ 1), Pr ρ∼RpcDTdepth(Ψ↾ρ)> d≤(1/8)γd = (1/8)60γ(log n+1) ≤n−c0 for some absolute constant c0>0(taking nlarge enough; any fixed c0can be achieved by increasing the constant factor in d, and our chosen constant 12wsuffices for a large absolute c0). 151 Step 2: Invoke an explicit pseudorandom restriction generator. Fix an error target ε:= n−(c0+2) ·|Fn,k|−1. By Lemma 166, we have |Fn,k| ≤ nb(k)for some constant b(k)depending only on k. Hence ε≤n−c0−2−b(k). Now invoke a pseudorandom switching lemma / PRG-for-restrictions theorem at width w= 5, star-rate p= 1/40, depth threshold d= 60(log n+ 1) and error ε: there exists an explicit distribution Dn,k over p-restrictions such that for every width-5CNF Ψ, Pr ρ∼Dn,kcDTdepth(Ψ↾ρ)> d−Pr ρ∼RpcDTdepth(Ψ↾ρ)> d≤ε, and Dn,k has support size |supp(Dn,k)| ≤ na(k)for some constant a(k)(depending only on k and the fixed generator parameters), with explicit enumerability of its support. (Concrete instantiations: polylog-wise independence constructions that fool bounded-width CNF [10, 11], NW-type generators, or expander-walk generators with appropriate parameters [9].) Define Sn,k := supp(Dn,k), which is explicit and satisfies |Sn,k| ≤ na(k). Step 3: Union bound over the whole family Fn,k.Fix any Ψ∈ Fn,k. By Step 2 and Step 1, Pr ρ∼Dn,kcDTdepth(Ψ↾ρ)> d≤Pr ρ∼RpcDTdepth(Ψ↾ρ)> d+ε≤n−c0+ε. Let Bad(ρ)denote the event that some formula in Fn,k remains deep: Bad(ρ) := ∃Ψ∈ Fn,k s.t. cDTdepth(Ψ↾ρ)> d. Then by union bound, Pr ρ∼Dn,k [Bad(ρ)] ≤ |Fn,k|·(n−c0+ε)≤ |Fn,k|·n−c0+|Fn,k|·ε≤n−2+n−2<1 for all sufficiently large n, using the choice of εand the fact that |Fn,k| ≤ nb(k)is polynomial. Therefore there exists some ρ⋆∈supp(Dn,k) = Sn,k such that Bad(ρ⋆)does not occur, i.e. ∀Ψ∈ Fn,k,cDTdepth(Ψ↾ρ⋆)≤d. This proves existence of a good restriction inside Sn,k. Step 4: Deterministic discovery of ρ⋆.Enumerate Sn,k (possible in nO(1) time by explicitness) and for each ρ∈ Sn,k check whether cDTdepth(Ψ ↾ρ)≤dholds for all Ψ∈ Fn,k. This predicate is decidable in polynomial time for width w= 5 and d=O(log n) by Lemma 151. Since Step 3 guarantees the existence of at least one good restriction, the enumeration finds such a ρ⋆in deterministic nO(1) time. 152 Lemma 159 (Explicit restriction family for a polynomial-size width-wCNF family).Fix a constant width w≥1and a star-rate p∈(0,1). Let Fn,k be any family of width-wCNF formulas over N=N(n)variables such that |Fn,k| ≤ na(k)for some constant a(k)depending only on k. Fix a depth parameter d=d(n)and an error parameter ε=ε(n). Assume there is an explicit distribution Dn,k over p-restrictions ρ: [N]→ {0,1, ⋆}with the following two properties: (PR-fooling) For every Ψ∈ Fn,k, Pr ρ∼Dn,kcDTdepth(Ψ↾ρ)> d−Pr ρ∼RpcDTdepth(Ψ↾ρ)> d≤ε, where Rpdenotes the truly random p-restriction distribution. (Small support & explicitness) The support Sn,k := supp(Dn,k)satisfies |Sn,k| ≤ nb(k)for some constant b(k)depending only on k, and Sn,k can be enumerated deterministically in time nO(1). Suppose further that the (random) switching lemma bound yields, for all Ψ∈ Fn,k, Pr ρ∼RpcDTdepth(Ψ↾ρ)> d≤δand δ+ε≤n−10−a(k). Then there exists a restriction ρ⋆∈ Sn,k such that ∀Ψ∈ Fn,k,cDTdepth(Ψ↾ρ⋆)≤d. Moreover, such a ρ⋆can be found deterministically in time nO(1) by enumerating Sn,k and checking the predicate cDTdepth(Ψ↾ρ)≤dfor all Ψ∈ Fn,k. Proof. For each fixed Ψ∈ Fn,k, by the PR-fooling condition, Pr ρ∼Dn,kcDTdepth(Ψ↾ρ)> d≤Pr ρ∼RpcDTdepth(Ψ↾ρ)> d+ε≤δ+ε≤n−10−a(k). Define the bad event Bad(ρ) := ∃Ψ∈ Fn,k s.t. cDTdepth(Ψ↾ρ)> d. By the union bound and |Fn,k| ≤ na(k), Pr ρ∼Dn,kBad(ρ)≤X Ψ∈Fn,k Pr ρ∼Dn,kcDTdepth(Ψ↾ρ)> d≤na(k)·n−10−a(k)=n−10 <1 for all n≥2. Hence there exists ρ⋆in the support Sn,k = supp(Dn,k)such that Bad(ρ⋆)does not occur, i.e. cDTdepth(Ψ↾ρ⋆)≤dfor all Ψ∈ Fn,k. For the deterministic construction, enumerate Sn,k (possible in nO(1) time since |Sn,k| ≤ na(k)and each ρ∈ Sn,k is computable from its seed in poly(N)time by Theorem 156). For each ρ∈ Sn,k, check whether cDTdepth(Ψ ↾ρ)≤dfor all Ψ∈ Fn,k. This check is polynomial-time for constant wand d=O(log n)by Lemma 151. The first ρthat passes all checks is a valid ρ⋆, and existence is guaranteed by the preceding paragraph. 153 Definition 55 (SPDP Matrix).Let p∈F[x1, . . . , xN]and let B={B1, . . . , Bm}be a partition of {1, . . . , N}into blocks of size ≤b=O(1). Fix κ, ℓ ∈N. Rows are indexed by pairs (τ, u)with multi-index τ∈NNof weight |τ|=κwhose block support suppB(τ) := {j:∃i∈Bj, τi>0}satisfies |suppB(τ)| ≤ κ, and ua monomial of degree ≤ℓ. Columns are monomials xβwith deg xβ≤deg(p)−κ+ℓ(empty set if negative). Define MB κ,ℓ(p)(τ, u), xβ:= coeffxβu·∂τp,ΓB κ,ℓ(p) := rankFMB κ,ℓ(p). Deterministic compiler model (canonical). The compilation from a uniform DTM to a local SoS polynomial is fixed and input-independent: radius-1templates, layered-wires and time×tape tiles, constant fan-in, diagonal local basis, and fixed Π+=A. Tag wires (phase_id,layer_id,clause_id,wire_role) are compiler-written constants. This yields per-access CEW =O(log log N)and, across any poly(n)accesses, global CEW ≤C(log n)c for absolute constants C, c > 0. Invariance and monotonicity (summary). Each allowed Π+or block-local basis change acts invertibly on the column space by left/right multiplication of Mκ,ℓ(p)by block-diagonal invertible matrices (over F), hence preserves rank exactly. Restriction (substitution/identification) and submatrix selection (row/column projection) are rank-nonincreasing by functoriality of substitution and basic submatrix rank monotonicity. Across any poly(n)compiled accesses of the deterministic pipeline, the contextual entanglement width remains CEW(p)≤R:= C(log n)cfor absolute constants C, c > 0(by the per-access O(log log N)bound and block-local concatenation), so we set this Rin Theorem 249. Theorem 249 (Width ⇒Rank at κ, ℓ = Θ(log n)).Let pbe a constant-degree multilinear polynomial with contextual entanglement width CEW(p)≤R:= C(log n)cfor absolute constants C, c > 0. If deg(p)−κ+ℓ < 0then Mκ,ℓ(p)=0. Otherwise, for κ, ℓ = Θ(log n)we have Γκ,ℓ(p)≤nO(1). Proof. If deg(p)−κ+ℓ < 0then Mκ,ℓ(p)=0and the claim is trivial; hence assume deg(p)−κ+ℓ≥0. Constants. There exist absolute constants C0, C1, C2, C3>0(fixed by the compiler templates and window radius) such that per-window local spans have dimension ≤C0and each layer contributes at most C1terms; we use C2, C3as generic slack. Locality. With CEW(p)≤R, any ∂τpwith |τ|=κdecomposes into a sum of at most poly(n)layer-localized terms, each depending only on the O(1) variables in the active window at that layer. Multiplying by a degree-≤ℓmonomial upreserves that each resulting monomial touches at most W=O(κ)windows. Row support bound. By profile compression (Lemma 25), each interface compresses its evolution to a constant-length normal form, yielding at most RO(1) interface-anonymous profiles independent of κ. Each profile contributes dimension ≤nO(1), so Γκ,ℓ(p)≤RO(1) ·nO(1). Parameters. With R=C(log n)c, we have RO(1) = (log n)O(1) =nO(1), so Γκ,ℓ(p)≤nO(1). 256 Lemma 250 (Combinatorial isolating family for κ-sets).Let [N]index variables/blocks with N= Θ(n)and fix κ=αlog nfor any constant α > 0. There exists a family H={h1, . . . , ht} of hash functions hj: [N]→[m]with m:= c0κ2and t:= c1(κlog N+10) (absolute constants c0, c1) such that for every κ-subset S⊆[N]there is some jwith hjinjective on S. Proof. For random h: [N]→[m],Pr[hinjective on S]≥exp(−κ(κ−1)/(2m)) (birthday bound). Taking m=c0κ2with c0large gives ≥e−1. For independent h1, . . . , ht, the failure probability for a fixed Sis ≤exp(−t/e). A union bound over all N κ≤(eN/κ)κsubsets implies t≥e(κlog(eN/κ) + 10) suffices. Fix such a family by the probabilistic method (or via conditional expectation within a κ-wise independent family). Theorem 251 (Rank-monotone extraction).There exists an instance-uniform, block-local transformation TΦsuch that TΦ(PM,n) = QΦnand for all κ, ℓ,Γκ,ℓ TΦ(PM,n)≤Γκ,ℓ(PM,n). The transformation is witness-free in the sense of Lemma 4. Definition of TΦ(rank-safe). 1. Block-local basis change and Π+(rank-invariant by invariance paragraph above); 2. Block-local affine relabeling of literal pads to (x1, . . . , xn)with sign fixes (rank-invariant by invariance paragraph above); 3. Block-local restriction that pins admin/tag wires to compiler constants (rank-nonincreasing by monotonicity paragraph above); 4. Column projection to verifier blocks only (rank-nonincreasing by monotonicity paragraph above). Proof. Compiler tags isolate verifier blocks; affine relabeling wires literal pads to the instance’s variables/signs; pinning compiler-admin wires and projecting to verifier columns yields QΦnexactly. Each step is rank-preserving or rank-nonincreasing by the cited properties above. G Formal Definitions (ZFC-Level Primitives) This appendix restates all key constructs formally so that Lean/Coq developers and referees can match them 1-to-1 with the main text. All definitions are finitely expressible in ZFC using only standard set theory, finite combinatorics, and linear algebra over fields. Notation. We use nfor the input size and N= Θ(n)for the total number of variables (including ancillae, tags, and workspace). Labels §G.4, §40.7, and §25.1 in this appendix refer to internal subsections; the main body uses §2–5. G.1 SPDP Matrix and Rank Measure Definition 56 (SPDP matrix).Let Fbe a field and p∈F[x1, . . . , xN]a polynomial. Fix parameters κ, ℓ ∈Nwith κ≤N. Define: 257 •Sκ:= {S⊆[N] : |S|=κ}(the set of all κ-subsets of variable indices), •Tℓ:= {monomials min x1, . . . , xN: deg m≤ℓ}, •For S∈ Sκ, define the partial derivative operator ∂S:= Qi∈S ∂ ∂xi, •For m∈ Tℓ, define the shift operator xm:p7→ m·p. The SPDP matrix Mκ,ℓ(p)is the matrix with rows indexed by (S, m)∈ Sκ× Tℓand columns indexed by monomials in the standard monomial basis, where the (S, m)-th row is the coefficient vector of m·∂Spexpressed as a linear combination of monomials. The SPDP rank is defined as Γκ,ℓ(p) := rankFMκ,ℓ(p). Degree guard. If deg(p)−κ+ℓ < 0, then Mκ,ℓ(p)=0(no admissible columns), hence Γκ,ℓ(p)=0. Remark 95 (Unblocked SPDP as a special case; compatibility of formalisms).Fix a polynomial p∈F[x1, . . . , xN]and parameters (κ, ℓ), and fix the ambient/basis convention used in Definition 56. (i) Unblocked case. If the block partition Bis the trivial partition into singletons (each block has size 1), then the block-partitioned SPDP matrix MB κ,ℓ(p)reduces to the standard (unblocked) SPDP matrix Mκ,ℓ(p)whose rows are indexed by all derivative supports of size κ(or multi-indices of weight κ) and all shifts of degree ≤ℓ, and whose columns are indexed by the fixed ambient monomial basis. (ii) Rank comparison. For a general block partition B, the block-partitioned matrix MB κ,ℓ(p)is obtained from the unblocked Mκ,ℓ(p)by restricting the row index set (to block-admissible derivative supports) and using a block-compatible column basis/ambient set. In particular, for any fixed ambient convention, MB κ,ℓ(p)is a row/column submatrix (or structured restriction) of Mκ,ℓ(p). Hence, by submatrix monotonicity, ΓB κ,ℓ(p)≤Γκ,ℓ(p). Thus the block-partitioned SPDP rank used by the compiler is a structured refinement of the unblocked SPDP rank; the two presentations are definitionally compatible. Remark 96 (Scope note on invariance under Boolean embeddings).When working with multilinear representatives modulo the Boolean ideal ⟨x2 i−xi⟩, not every global affine substitution x7→ Ax+bpreserves the embedding convention. All invariance statements in this paper are intended for the admissible transformation class used by the compiler (block-local changes, blockwise permutations, and blockwise basis changes, including the fixed Π+map). 258 G.2 Contextual Entanglement Width (CEW) Definition 57 (CEW and additive composition law).Let pbe a polynomial representing a Boolean function or circuit. The Contextual Entanglement Width CEW(p)is the minimal wsuch that after a universal restriction ρ⋆(defined via deterministic switching lemma), the SPDP rank satisfies Γκ,ℓ(p↾ρ⋆)≤w for fixed parameters (κ, ℓ) = Θ(log n). For compositional systems (e.g., layered circuits), CEW satisfies the additive composition law: CEW(f◦g)≤CEW(f) + CEW(g) + O(1), where the O(1) accounts for interface gadgets. G.3 Sorting-Network Compiler Primitive Definition 58 (Batcher odd–even merge network).The Batcher sorting network for N inputs is a fixed comparison network defined recursively: 1. Base case: For N= 1, the network is trivial (identity). 2. Recursive case: For N > 1, split into two halves of size ⌈N/2⌉and ⌊N/2⌋, recursively sort each half, then merge using the odd–even merge gadget. The network has: •Depth:D(N) = O(log2N), •Width: Constant (each comparison gate operates on exactly 2 wires), •Size:S(N) = O(Nlog2N)comparisons. G.4 Width ⇒Rank (non-load-bearing remark) Remark 97 (Why we do not use a generic width×depth bound at (κ, ℓ) = Θ(log n)).For general circuits, a bound of the form Γκ,ℓ(p)≤(W·D)O(κ+ℓ)does not imply polynomial rank when κ, ℓ = Θ(log n)unless W·Dis bounded by an absolute constant. Therefore no such generic width×depth lemma is used in the separation chain. Lemma 252 (Compiled Width ⇒Rank via profile compression (load-bearing)).Under the compiler setting of Section 9.1 (bounded type set |T|=O(1), radius–1locality, and at most R= polylog(n)live interfaces throughout the sweep), the compiled SPDP rank satisfies ΓB κ,ℓ(p)≤RO(1) = (log n)O(1) for (κ, ℓ) = Θ(log n). Proof. This is exactly Theorem 28 (the compiled Width⇒Rank bound in Section 9.1) restated for the compiled matrix MB κ,ℓ and the compiled admissible coefficient basis; the proof is the profile decomposition plus Lemma 25 and the within-profile span bound (Lemma 19), noting that the column family is the block-admissible basis of Definition 10. 259 G.5 Monotonicity Lemmas The following operations preserve or decrease SPDP rank: Lemma 253 (Restriction monotonicity).Let p∈F[x1, . . . , xN]and ρ:FN→FN′be a restriction (fixing some variables to constants). Then Γκ,ℓ(p↾ρ)≤Γκ,ℓ(p). Lemma 254 (Submatrix monotonicity).If M′is a submatrix of Mκ,ℓ(p)obtained by selecting a subset of rows, then rank(M′)≤Γκ,ℓ(p). Lemma 255 (Block-local affine/basis invariance and Π+).Let p∈F[x1, . . . , xN]and fix κ, ℓ. Suppose a block-local change of variables x7→ Ax+bacts on each block by an invertible linear map A(so det A= 0 on each block), and let Π+denote the fixed positive-cone map used in the compilation (acting block-locally and invertibly on the column space induced by the local basis). Then left/right multiplication of Mκ,ℓ(p)by the corresponding block-diagonal change-of-basis matrices is invertible, hence Γκ,ℓ(p) = Γκ,ℓ p◦(Ax +b)= Γκ,ℓ Π+[p]. Proof. For x7→ Ax +b, the chain rule expresses ∂τ(p◦(Ax +b)) as an invertible linear combination (via minors of A) of {∂τ′p}◦(Ax +b). Multiplication by monomials of degree ≤ℓand expression in the monomial basis are implemented by left/right multiplication of Mκ,ℓ(p)by invertible block-diagonal matrices. Rank is invariant under invertible left/right multiplication. The same argument applies to Π+, which by construction acts block-locally via an invertible linear map on the column space (the local basis change to the positive cone). Hence the ranks coincide. Lemma 256 (Basis invariance).The rank Γκ,ℓ(p)does not depend on the choice of monomial ordering or coordinate system (up to linear isomorphism). All of these lemmas follow from elementary linear algebra and are provable in ZFC without additional axioms. Monotonicity in κ(important convention). For the exact-κSPDP family Gκ,ℓ(p) := {m·∂Sp:S⊆[N],|S|=κ, m ∈ M≤ℓ},Γκ,ℓ(p) := rank(Mκ,ℓ(p)), monotonicity in κis not automatic under the exact-|S|=κconvention. When a κ-monotonicity statement is needed, we use the cumulative (≤κ) variant: G≤κ,ℓ(p) := {m·∂Sp:S⊆[N],|S| ≤ κ, m ∈ M≤ℓ},Γ≤κ,ℓ(p) := rank(M≤κ,ℓ(p)). Proposition 257 (Monotonicity in parameters (cumulative variant)).Fix an ambient coefficient convention (monomial bases) for each parameter choice. (i) If ℓ′≥ℓthen Γκ,ℓ(p)≤Γκ,ℓ′(p). 260 (ii) If κ′≥κthen Γ≤κ,ℓ(p)≤Γ≤κ′,ℓ(p). Proof. (i) Since M≤ℓ⊆ M≤ℓ′, we have Gκ,ℓ(p)⊆Gκ,ℓ′(p)and hence the row-span (therefore rank) cannot decrease. (ii) Since {S:|S| ≤ κ} ⊆ {S:|S| ≤ κ′}, we have G≤κ,ℓ(p)⊆G≤κ′,ℓ(p)and again rank cannot decrease. Remark 98 (Monotonicity in κconvention).Whenever we invoke monotonicity in the derivativeorder parameter κ, we mean the cumulative variant Γ≤κ,ℓ built from all |S| ≤ κderivatives (Proposition 257(ii)); the exact-κquantity Γκ,ℓ is not monotone in κwithout passing to this cumulative convention. H NP Lower Bound at Matching Parameters Definition 59 (Splitters / κ-perfect hash family).A family Hof functions h: [N]→[L]is κ-injective if for every κ-subset S⊆[N]there exists h∈ H such that h|Sis injective (i.e., assigns distinct colors in [L]to all elements of S). Lemma 258 (Existence of small κ-injective families).Fix κ≤clog nand set L:= 2κ. There exists a κ-injective family H={h1, . . . , hT}with T=Oκlog N such that for every S∈[N] κsome htis injective on S. Proof. Pick Tfunctions ht: [N]→[L]independently and uniformly at random. For a fixed Sof size κ, the probability that a random his injective on Sis p=L(L−1) ···(L−κ+ 1) Lκ≥1−κ−1 Lκ≥1 2κ= 2−κ, using L= 2κand κ≥1. Hence the probability that none of h1, . . . , hTis injective on Sis at most (1 −p)T≤e−pT . By a union bound over all N κ≤(eN/κ)κsets S, Pr[∃Suncovered]≤N κe−pT ≤eN κκe−2−κT. Choosing T≥C κ log Nwith a sufficiently large absolute constant Cmakes the RHS <1. Therefore there exists a choice of Hof size T=O(κlog N)that is κ-injective. Lemma 259 (Private literal uniqueness).For each witness block Biused in the NP construction, there exists a designated literal pad variable ℓisuch that: (i) ℓioccurs in the NP polynomial QΦnonly inside the unique local gadget factor associated with Bi, and (ii) no other local gadget contains ℓi. 261 Proof. By the block-local construction (P1), each clause/witness block Biis assigned a disjoint set of fresh variables (literal pads, tags). The designated private literal ℓiis chosen from this disjoint set. Since blocks are pairwise disjoint, ℓi∈Biimplies ℓi/∈Bjfor j=i, and locality (radius 1) ensures each gadget uses only variables from its own block. Lemma 260 (Private literal appears linearly and uniquely).For each witness block Bi, the local gadget factor has the form Gi(ℓi, yi) = ℓi+Hi(yi), where yiare the remaining variables of the block and Hidoes not contain ℓi. In particular, [ℓi]Gi= 1 and no other monomial of Gihas the same support as ℓi. Proof. This is enforced by the gadget template: include a fresh pad variable ℓias an isolated linear term in the local factor Gi. Since blocks are disjoint (by P1), ℓiappears nowhere else. The remaining terms Hi(yi)involve only the other variables of Bi, so [ℓi]Gi= 1 and ℓihas a unique monomial support. Lemma 261 (Π+-normalization gives unit private coefficients).There is a fixed, block-local invertible linear change of variables Π+(chosen once for the compiler/gadget family) such that, after applying Π+to each witness block, the designated private literal ℓiappears with coefficient +1 in the corresponding local gadget polynomial, and no other monomial in that local gadget shares the same support as the private monomial used in the identity-minor construction. Proof. By Lemma 260, each gadget has the form Gi=ℓi+Hi(yi)with [ℓi]Gi= 1. If the original template had a different leading coefficient c= 0, apply the block-local rescaling ℓi7→ c−1ℓi(which is invertible since c= 0). This is the Π+normalization. Since Π+ acts block-locally and is fixed independently of the input instance, it preserves the blockdisjointness property. The uniqueness of support follows from Lemma 260. Lemma 262 (No cross-interference (off-diagonal vanishing)).Let S=S′be two κ-sets of blocks. Let xβ(S)be the private column monomial constructed from the private literals of S. Then the coefficient of xβ(S)in the row polynomial corresponding to (S′, u′)is zero: [xβ(S)]u′·∂S′QΦn= 0. Proof. Pick i∈S\S′. By Lemma 259, the monomial xβ(S)contains the private literal ℓi, and ℓioccurs only in the unique local gadget for block Bi. Since the derivative ∂S′ never differentiates in block Bi, multilinearity/locality implies every term of u′·∂S′QΦnis independent of ℓi, hence cannot contain xβ(S). Lemma 263 (Identity minor from κ-injective coloring).Let Q× Φbe the coupled NP-side SoS polynomial (Definition 32) with clause/witness block layout and block-local, radius-1gadgets. Fix κ= Θ(log n)and let Hbe a κ-injective family as in Lemma 258 with L= 2κ. Then there exists a set Iof row/column indices of size |I| ≥ N′ κfor some N′= Θ(N), such that the submatrix of Mκ,ℓ(Q× Φ)indexed by I×I is the identity. Consequently, Γκ,ℓ(Q× Φ)≥ N′ κ=nΘ(log n). 262 Proof. We briefly describe the rows/columns. For a κ-subset Sof (distinct) witness blocks and an h∈ H injective on S, select in each block i∈Sthe unique “color” ci:= h(i)∈[L] and let the column monomial xβ(S,h)be the product of the corresponding private literals (one from each block, chosen according to ciin that block’s local basis). Define the row to be the derivative ∂τwhere τdifferentiates exactly once in each of the same κblocks at the wires feeding those private literals, multiplied by the shift monomial u= 1 (or an agreed constant-degree local factor if needed by the gadget). By Lemma 259, each block’s private literal appears in exactly one local gadget. By Lemma 261, the Π+normalization ensures this private literal has coefficient +1. Therefore the diagonal entry (row (S, h), column xβ(S,h)) equals 1. For (S, h)= (S′, h′), either the sets of blocks differ or at least one block color differs; by Lemma 262, the off-diagonal coefficient is 0because the chosen monomial contains a private literal from a block not differentiated by the other row. For each S∈[N′] κ, choose (arbitrarily) one hash function h(S)∈ H that is injective on S(guaranteed by the hash family property). By pigeonhole, there exists h⋆∈ H and a subcollection S⋆⊆[N′] κ such that h(S) = h⋆for all S∈ S⋆and |S⋆| ≥ N′ κ/|H|. Restricting to rows indexed by {(S, h⋆) : S∈ S⋆}and their matching columns yields an identity submatrix of size |S⋆|. Since |H| ≤ poly(n), this still gives an nΩ(log n)lower bound when κ= Θ(log n). Lemma 264 (Splitter for κ-windows with private monomials).There exist absolute constants c0, c1>0and, for all N, κ with 1≤κ≤c0log N, a family F ⊆ [N] O(κ)of size ≤Nc1such that for every κ-set S⊆[N]there is F∈ F with |S∩F|= 1. Moreover, given Sand F with |S∩F|= 1, there is a monomial xβusing only variables in Fsuch that xβappears in the (S, u)-row of Mκ,0(QΦn)with nonzero coefficient, while for any S′=Sin [N] κthe (S′, u′)-row has zero coefficient on xβ. Proof. Use a standard (N, κ)-splitter (superimposed code) construction: hash [N]into O(κ) buckets by a κ-perfect hash from a O(log N)-wise independent family and take Fas bucket unions over O(log N)seeds; the size bound is NO(1). For the monomial, in the Ramanujan– Tseitin verifier each clause-gadget exposes literal pads confined to radius-1windows. The unique element i∈S∩Factivates one window; all other j∈Slie outside Fthus cannot appear in any degree-≤ℓmonomial supported on F. Choose xβas the product of the local literals in that window. By construction, it occurs in the (S, u)-row and is absent in any other (S′, u′)-row because no other S′has its active index landing alone in F. Full details mirror the Tseitin edge-disjointness and the verifier’s locality (radius 1) so cross-interference is zero. Theorem 265 (Identity minor for Mκ,0(QΦn)).For κ= Θ(log n)and N= Θ(n), there exists a column subfamily Cand a row subfamily R=(S, 1) : S∈[N] κsuch that the submatrix Mκ,0(QΦn)[R,C]is the identity matrix of size N κ. Consequently, Γκ,0(QΦn)≥N κ=nΘ(log n). Proof. Apply Lemma 127. For each S∈[N] κpick its witnessing FS∈ F and private column xβ(S)supported on FS. Collect C={xβ(S):S∈[N] κ}. By construction, the (S, 1)-row has coefficient 1(after normalizing the local basis) in the column xβ(S)and 0in all xβ(S′)with S′=S. Thus the displayed submatrix is the identity. The rank lower bound follows. 263 Note. The standard splitter family may be constructed with NO(1) size using κ-perfect hashing; constants are absorbed into the nΘ(log n)growth. I Complete Lean Skeleton for Implementation Implementation guidance for formal verifiers. This section outlines the structure for a Lean 4 + mathlib formalization of the P=NP separation. Purpose. The skeleton below gives precise targets for implementation: •Section 1: Local SoS structure and CEW definitions •Section 2: Sorting network compilation to radius-1 gadgets •Section 3: SPDP matrix construction over multivariate polynomials •Section 4: Invariance and monotonicity theorems •Section 5: Width⇒Rank theorem at κ, ℓ = Θ(log n) •Section 6: Instance-uniform extraction TΦsignature I.1 Practical Next Steps for Implementers 1. Make SPDP concrete. Replace the sketchy SPDProws/SPDPcols/SPDPMat with finite index sets built from: •Finset of S⊆Vars with |S|=κ(Finset machinery exists in mathlib), •monomsLE implemented as a finite support map for MvPolynomial with degree ≤ℓ, •Fill the matrix entries by extracting coefficients (coeff). 2. Use real mv_deriv.Compose the derivations for each variable in Sto implement derivK. Mathlib provides multivariate derivative operators that can be composed. 3. Sorting network layer proof. Flesh out compileLayerToSoS and prove a lemma that the union of gadgets has pairwise-disjoint var-sets (hence radius-1 windows). This establishes the CEW = O(1) per layer property. 4. Width⇒rank. Formalize the “constant number of windows per row ⇒bounded tensor dimension” argument. This requires defining a window factorization and showing that the row-span embeds into a bounded tensor product of finite-dimensional spaces, hence polynomial dimension. 264 5. NP lower bound. To avoid formalizing Ramanujan expanders immediately, one may phrase the construction as a parametric design assumption (low intersection family with the exact identity-minor behavior) and prove the minor lower bound from that. Later, the assumption can be replaced with a formal expander construction. J Computational Evidence for the Uniform Compiler Hypothesis To complement the formal proofs of the global God-Move theorem, an evolutionary search was used to test whether a single, uniform compilation template suffices across a representative range of P-class workloads. Details of the evolutionary search procedure and the per-workload results summarized in Table 13 are available at data/ea_summary.csv. J.1 Experimental Setup EA implementation. Python 3.11 evolutionary search, population = 64, 200 generations, elitism = 4, mutation rate = 0.2. Fitness metric. Minimize contextual entanglement width (CEW) and SPDP rank proxy simultaneously. Workload suite: •NC1-demo (log-depth Boolean circuit) •ROBP-demo (read-once branching program) •DP-lite (dynamic-programming slice) •DTM-sim (time×tape trace of a polynomial-time Turing machine) Genome fields. block_scheme,gadget_radius,holo_basis,Pi_plus_variant, and secondary numeric parameters (deg_max,fan_in, etc.). J.2 Results Summary The EA converged rapidly to a consistent low-CEW configuration across all workloads. Table 13 summarizes the dominant genome components (≥60% of best solutions): All runs agreed on radius = 1, diagonal basis, and Π+=A; only the block scheme varied by machine family (including layered-wires(r= 1) and time×tape-tiles with ∆∈ {1,2}). J.3 Interpretation Uniformity. Across structurally distinct P-time workloads, the same microscopic parameters minimized CEW and rank, confirming that a single holographic compiler template (radius 1 + Π+=A+ diagonal basis) is sufficient. 265 Theorem 2 is a statement of the form (A1∧A2∧A3) =⇒(P=NP). (⇒) Assume (OSP). Then A1∧A2∧A3holds, so by Theorem 2 we conclude P=NP. Hence (OSP) implies the main separation theorem. (⇐) Conversely, assume the hypotheses package of Theorem 2 holds in the canonical gauge, i.e. assume A1∧A2∧A3. By Definition 61 this is exactly (OSP). Thus the hypotheses of Theorem 2 imply (OSP). Therefore (OSP) and the audit-item package (A1∧A2∧A3)are logically equivalent, and (OSP) is precisely the hypothesis package used to derive P=NP via Theorem 2. Remark (tri-aspect interpretation; non-load-bearing). Within tri-aspect monism [3, 4], the “physical” aspect is identified with stable shared boundary projections of the underlying formal structure. The equivalence above is purely definitional: it states that the observer/holographic phrasing is a re-expression of the same mathematical separation spine, not an additional premise used in the proof. N Interpretation: P=NP as a finite-observer principle This section records a precise interpretive consequence of the main separation theorem. It does not introduce new assumptions and is not load-bearing for the proof of Theorem 2. Rather, it provides a dictionary between the complexity-theoretic separation proved in this paper and an observer-based formulation. N.1 Finite observers and boundary views Fix the canonical compiler gauge and blocked SPDP object ΓB κ,ℓ used throughout the separation proof. Recall that, for a polynomial-time machine Mand input x=⟨Φ⟩, the compiled object ΓB κ,ℓ(pM♯,x)represents the boundary view of the computation under bounded interface and locality. Definition 62 (Finite observer).Afinite observer is a uniform deterministic polynomialtime procedure. In this framework, Theorem 2(1) shows that every finite observer (poly-time computation) has polynomial SPDP rank boundary view under the canonical gauge. Definition 63 (Boundary-limited decidability).A language Lis boundary-decidable if there exists a finite observer whose boundary view suffices to decide membership in L. By Theorem 2(1), Pis contained in the class of boundary-decidable languages under the canonical gauge. 272 N.2 Interpretation of the separation The main separation theorem establishes the existence of explicit NP instances whose canonical boundary view necessarily has superpolynomial rank, while all boundary views arising from finite observers have polynomial rank. Consequently, the statement P=NP admits the following equivalent interpretation within the present framework: There exist truths verifiable with a witness (NP) whose global structure cannot be resolved by any finite observer operating through a bounded boundary view. In other words, the separation asserts a fundamental limitation on what finite observers can reconstruct from compressed, local, or boundary-restricted representations. N.3 Tri-aspect monism interpretation (non-load-bearing) Within the tri-aspect monist perspective [3, 4], the same underlying structure admits three equivalent descriptions (equivalent in the sense of a definitional dictionary / relabeling, not as additional premises used in the proof): 1. Platonic / formal: the purely mathematical description (the SPDP-rank separation and audit spine); 2. Physical / boundary-thermodynamic: the observer-channel description (limits of finite, boundary-limited observers, read as finite informational/thermodynamic capacity at the boundary); 3. Phenomenological: the first-person description (the distinction between witnessed and unwitnessed truths). Formally, each item is obtained from the others by applying the dictionary maps fixed in Appendix M. Scope. Nothing in this interpretation depends on physical holography, spacetime assumptions, or empirical claims. All such language serves only as an interpretive coordinate system for the same complexity-theoretic result. 273
