We propose and prove two unified propositions: first, \textit{mathematical structures} are necessary expressions of \textit{physical constraints}; second, \textit{logical rules} are algebraic characterizations of \textit{causal structures}. The construction path: taking windowed scattering--information geometry--static block observation--reversible logs (WSIG--EBOC--RCA) as the object layer, using the ``master-scale identity'' (MSI) as the observational ruler, establishing a hyperdoctrine composed of realizable predicates and completing it via tripos$\to$topos to obtain internal logic; then characterizing the compatibility of deduction rules and causal partial order via string diagram semantics of dagger symmetric monoidal categories. The core conclusion shows: physical self-consistency satisfying causality, unitarity/complete positivity, energy-spectrum--phase--group-delay co-calibration (MSI), and NPE (Poisson--Euler--Maclaurin--tail) error discipline is equivalent to complete deducibility of some internal logic; and the structural rules of this logic correspond precisely to ``copyable/discardable'' classical wires and quantum channels restricted by resource sensitivity. The paper provides: spectral shift--scattering determinant--group delay co-calibration identity and windowed trace formula; geometrized quantum dynamics on projective Hilbert space; measurement closure via Belavkin filtering and GKSL semigroups; boundary/lens rigidity and metric inversion; integerized calibration via Zeckendorf reversible logs.

We construct a unified framework of Windowed Scattering--Information Geometry (WSIG) centered on the ``operator--measure--function'' triple: observation is operationalized through Toeplitz/Berezin compression Kw,h=ΠwMhΠw, reducing all readouts to linear functionals on spectral measures. The trinity scale identity φ′(E)/π=ρrel(E)=(2π)−1trQ(E)=−ξ′(E) unifies phase, relative density of states, and Wigner--Smith group delay as master scales. For observer filter chains {Kθ}θ∈Θ, we define an information action S and induce an information metric via the Hessian gμν=∂μ∂νS, interpreting connection and curvature as second-order non-commutative responses of readouts to observation parameters. Under the ``double-time separation'' postulate---where causal partial order is uniquely defined by frontier time t∗ while windowed group delay Tγ[w,h] serves only as operational scale---variation of the action A=(2κ)−1∫(R−2Λ)∣g∣dnθ+∫(Linfo+λμν[gμν−∂μ∂νSloc])∣g∣dnθ yields Einstein-type equations Gμν+Λgμν=κTμν. The right-hand stress-energy tensor Tμν arises from spectral responses of Kθ. Under band-limited and Nyquist--Poisson--finite-order Euler--Maclaurin (NPE) discipline, we achieve error closure with ``non-increasing singularity: poles = master scales''. Within the same geometric framework, we unify quantum measurement: superposition = convex superposition of compatible components in static blocks; collapse = anchor switching and π-semantic collapse; entanglement = inseparable information correlations in causal networks. Continuous monitoring satisfies GKSL dynamics and Spohn entropy production monotonicity, with Belavkin filtering providing conditional state updates. Core criteria and required external theorems are provided, along with one-dimensional potential scattering examples and complete proof chains.
Under the unified perspective of ``discrete--static blocks (EBOC)'' and ``continuous--causal manifolds/gauge systems,'' we construct an axiomatic framework for quantum measurement: wave functions are characterized as complex-amplitude superpositions of compatible SBUs (Static Block Units) in static blocks; collapse is characterized as observer anchor switching and π-semantic collapse from operator algebras to classical record algebras; entanglement is characterized as conditional mutual information and quantum Markov property in causal networks. Mathematically, quantum instruments and POVMs serve as core objects, with Stinespring/Naimark/Kraus representations, Lüders update, relative entropy minimization principle, and Belavkin filtering closing the ``measurement--update--record'' chain; at the information-geometric level, strong subadditivity and conditional mutual information control causal propagation of entanglement and ``no-signaling.'' At the readout--geometry interface, employing windowed compression Kw,h and ``trinity master-scale'' πφm′=ρrel=2π1trQ unified readout framework, with non-asymptotic error closure under Nyquist--Poisson--Euler--Maclaurin (finite-order) discipline; this identity holds almost everywhere on absolutely continuous spectrum, thereby rigorously unifying ``phase derivative--relative spectral density--Wigner--Smith group delay.'' Davies--Lewis instruments/POVMs, postulated Lüders rule, Stinespring--Kraus--Naimark representations, and Belavkin continuous measurement stochastic filtering provide testable anchor points; Birman--Kreĭn identity, Kreĭn--Friedel--Lloyd bridge, and de Branges kernel diagonal formula provide spectral/functional-analytic basis for unified readout of ``windowed--spectral--scattering.''
Within the unified context of ``universe = Generalized Light Structure (GLS),'' ``observer = filter chain (windowed compression → CP channel → POVM → threshold counting),'' and ``causality = lightlike cone preorder,'' we establish an axiomatic theory with the master scale πφ′(E)=ρrel(E)=2π1trQ(E),Q(E)=−iS(E)†dEdS(E) (phase derivative---relative density of states---Wigner--Smith group delay trace). \textbf{Causal red line:} Windowed group delay readout Tγ[wR,h] serves solely as operational time scale (can be negative in narrowband/resonance, having no universal size comparison with wavefront time t∗); causality determined exclusively by t∗ and lightlike cone partial order. Core results: (i) windowed group delay readout provides operational time scale, proven series-parallel additive and gauge covariant/relatively invariant (invariant when U,V energy-independent or more generally ∂E(argdetU+argdetV)=0); in vacuum links satisfying Nyquist discipline, high-frequency/alias-free limit aligns with wavefront velocity calibrating c; (ii) redshift characterized by spectral scaling with reciprocal time scaling law; (iii) light speed c normed by vacuum wavefront, yielding wavefront lower bound and no-supercone propagation for arbitrary physical channels; (iv) ``GLS ↔ causal manifold'' mutual construction outline with skeleton and consistency conditions---rigorous proof and naturality verification in separate work; (v) wave-particle duality and double-slit windowed complementarity D2+V2≤1 unified in same ledger; (vi) spectral resolution enhancement (bandwidth narrowing) and redshift amplification are dual; conversely, temporal/image resolution enhancement (σT decrease) and blueshift (bandwidth increase) are dual, consistent with σT≳Cw,h/B in \S4.4, yielding Nyquist--Poisson--Euler--Maclaurin (NPE) finite-order error closure and engineering prescription; (vii) high-frequency platform bridge: under \S4 premises, blueshift limit of any fixed-shape normalized window family---single channel limE0→∞Tγ=t∗, multichannel limE0→∞TC=Nefft∗ and per-mode average limE0→∞TC=t∗, treating causal wavefront t∗ as operational limit scale of Tγ and TC. Theory employs operator-measure-function language throughout (Toeplitz/Berezin compression Kw,h, readout = linear functional on spectral measure), unifying all time/density readouts under global unitarity postulate by Q=−iS†S′; experimental non-unitarity traced back to master scale via unitary dilation S.
Under four testable conditions---global unitarity/reversibility, finite memory/Markovizability, bandlimiting with Nyquist--Poisson--Euler--Maclaurin (NPE) finite-order closure, and time-ledger alignment---we construct functors F:EBOC→GLS and G:GLS→EBOC with natural transformations η,ϵ, and prove that they are mutually equivalent in the observation category. The bridge is provided by the master-scale identity πφ′(E)=2π1trQ(E),ρrel(E)=ξ′(E)=−2π1trQ(E), implying φ′(E)/π=−ρrel(E) (where Q=−iS†∂ES), and the windowed trace identity. The NPE discipline yields discretization and endpoint--tail closure in a non-asymptotic manner without introducing novelties. Thus, EBOC's ``static blocks--factor decoding--complexity/entropy ledger'' and GLS's ``unitary scattering--group delay--windowed measure'' are window-by-window consistent.
Within the unified framework of Windowed Scattering and Information Geometry (WSIG), Eternal Block Observer-Computing (EBOC), and Reversible Cellular Automata (RCA), we define the window--group delay ratio for any observational triple (\mathcal H,w,S) as $ \chi(\mathcal H,w,S):=\Delta[w]{\langle\tau_g\rangle_w}, where \Delta[w] is the effective span of window w, and \langle\tau_g\rangle_w is the window-weighted average of Wigner--Smith group delay. Under Assumption A (§1), we prove that \chi is an invariant under all reversible observational transformations (information-preserving coordinate/scale rescaling, unitary prefiltering, frame/sampling rearrangement, and reversible lattice updates), with the common value denoted c. In the spacetime geometric interpretation, taking \Delta[w] as effective spatial length and \langle\tau_g\rangle_w as time delay, c is equivalent to the maximal slope of the reachable signal cone, isomorphic to the speed of light constant. This construction is anchored in the following established chain identities and criteria: unification of phase derivative--spectral shift density--group delay (a.e. on absolutely continuous spectrum), Birman--Kreĭn identity and trace characterization of Wigner--Smith matrix \mathsf Q=-i\,\hbar\,S^\dagger \partial_E S; NPE non-asymptotic error theory for windowed readouts; Wexler--Raz conditions, Landau density threshold, and Balian--Low obstruction for Gabor/non-stationary Gabor frames; and ``read-commit'' consistency of I-projection and Ky--Fan minimization. At singularities/thresholds, zero-pole structure is controlled by de Branges--Kreĭn and Rouché-type stability criteria, ensuring verifiable stability of \chi. We further prove that the ``front slope'' refinement limit c_{\rm RCA} of RCA is consistent with the continuous scattering side constant c$, and provide reproducible experimental protocols for multi-window--multi-channel configurations (including sampling rate, window order, and confidence interval construction).
We develop a mathematical framework in which physical description is organized through predictively sufficient closure of richer realization spaces. A closure map identifies realizations that are equivalent relative to specified observables, while dynamic sufficiency requires the induced reduced state to support autonomous evolution. This yields a precise formulation of the principle that law can close before realization does: a law-level state may be fully predictive within a declared domain even when multiple underlying realizations remain possible. We distinguish quotient closure, realization fibers, idempotent closure maps, refinement, partial closure, closure memory, obstruction, and saturation of multiple closure constraints. These structures are then tested against explicit physical examples involving compact phase winding, topological defects, gauge compensation, exchange statistics, spinorial closure, quantum measurement channels, and effective propagation geometry. The analysis exposes several limitations of a motivating one-scalar coherence construction. In particular, a smooth exact phase connection has vanishing local curvature; a relative phase does not generate orthogonality or Pauli exclusion; winding alone does not supply spin- or the observed electric-charge spectrum; and a single scalar gradient cannot define a generic nondegenerate four-dimensional metric. Rather than abandoning the coherence hypothesis, these obstructions motivate a minimally enriched effective architecture involving amplitude/phase, gauge connection, spinor, and geometric frame sectors. We distinguish this effective reconstruction from the stronger hypothesis that all such structures descend from a common parent coherence object. The resulting framework does not claim a completed derivation of the Standard Model, general relativity, or quantum measurement. Instead, it identifies the mathematical and physical gates such derivations must satisfy and isolates noncommuting saturation, closure obstruction, representation reconstruction, stable particle sectors, and universal emergent geometry as principal theorem and physics programs.
