Preprint: This work is a preprint, has not undergone peer review, and is made publicly available to establish a public scientific record. This publication presents operational one-dimensional scaling tests of the Dynamical Information Geometry (DIG) framework using the Twin-Test protocol. Dynamical Information Geometry assigns an effective, state-dependent geometry to quantum many-body dynamics based on the spatial organization of mutual information. Earlier parts of the DIG series established the theoretical framework, provided numerical validation, introduced hardened operational definitions, and clarified regime structure and necessity. The present work, DIG Part VI, does not introduce new theory, new observables, or new numerical modeling. Its role is strictly operational. It documents how the Twin-Test protocol behaves under controlled one-dimensional scaling variations along two independent axes: system-size increase in a simulator implementation and circuit-depth increase in a quantum hardware implementation. Both scaling axes are evaluated within the same operational framework, using the mandatory audit logic defined in DIG Part IV. No attempt is made to relate or map these axes onto one another. The analysis is restricted to structural sign behavior, audit classification (marker-stable versus marker-transfer), and the identification of an operational robustness limit (defect) at increased depth. No universal scaling laws are proposed. No fitting, extrapolation, or cross-platform amplitude matching is performed. All operational definitions and decision rules are stated explicitly in the manuscript. The accompanying dataset implements these rules verbatim and enables deterministic third-party reproduction without interpretation.

Preprint: This work is a preprint, has not undergone peer review, and is made publicly available to establish a public scientific record. This work establishes the regime structure, structural invariance, and an operational no-escape result for the Dynamical Information Geometry (DIG) framework. DIG assigns an effective, state-dependent information geometry to quantum many-body systems via the curvature of a coarse-grained mutual-information profile. Earlier work introduced the theoretical framework, provided numerical evidence for slowing and acceleration of operator fronts, and validated a minimal operational consequence on quantum hardware. The present work addresses a distinct question: Which structural and operational consequences follow from the Twin Test observations under the assumptions of unitary dynamics, finite information propagation, and compositionality? This manuscript introduces no new theoretical framework, equations of motion, fits, or scaling laws. Instead, it consolidates and hardens the operational consequences of DIG by: establishing that the DIG response exists only within a finite onset–window–breakdown regime; demonstrating form invariance of the response across implementations (system size, architecture, and hardware platform); introducing mandatory operational audits and a deterministic observable-selection rule that prevents the misreading of the Twin Test as marker persistence; formulating an operational no-escape result: within the Twin-protocol class, any explanation compatible with unitary dynamics, finite information propagation, and compositionality necessarily induces a state-dependent information-geometric cost structure. The Twin Test is treated as a structured existence test, not a statistical procedure. All reported results are sign-based and strictly operational. No fitting, extrapolation, noise mitigation, or cross-platform normalization is applied. The work documents Twin-Test realizations on heterogeneous quantum hardware platforms, including superconducting qubits and trapped-ion systems, and shows that apparent discrepancies (such as marker transfer on specific devices) are regime-diagnostic rather than failures, indicating that DIG operates as a bounded phenomenon. All numerical and hardware results reported in this paper are fully reproducible from the accompanying public dataset without additional assumptions.

Preprint: This work is a preprint, has not undergone peer review, and is made publicly available to establish a public scientific record. This work reports an experimental two-dimensional validation of the Dynamical Information Geometry (DIG) Twin-Sign protocol under fixed audit and regime constraints. Dynamical Information Geometry assigns an effective, state-dependent information geometry to quantum many-body dynamics via the curvature of a coarse-grained mutual-information profile. Earlier work introduced the theoretical framework (Part I), provided numerical evidence for sign-sensitive refraction effects (Part II), validated a minimal operational consequence on quantum hardware (Part III), established regime structure and operational necessity (Part IV), and formulated the intrinsic tensorial nature of information curvature in dimensions greater than one (Part V). The present work occupies a strictly operational and consolidating role within the DIG series. It does not introduce new theoretical postulates, derivations, observables, or interpretive claims. Instead, it tests whether the multidimensional, projection-based structure articulated in DIG Part V remains internally consistent when subjected to the mandatory audit logic and regime language fixed in DIG Part IV. Twin-Sign tests are performed in two spatial dimensions along two non-collinear directions, without privileging any spatial axis. All results are derived exclusively from raw measurement counts under fixed audit invariants. No readout mitigation, post-selection, fitting procedures, or cross-platform normalization is applied. In addition to positive validation runs, the dataset includes a structurally defined negative control (One-Sided Twin), which is shown to fail deterministically. Across sampled values of the lens-strength protocol parameter, the observed outcomes recover the finite onset–window–breakdown regime structure introduced in DIG Part IV. This behavior is reported descriptively, without invoking universality, sharp thresholds, or new scaling claims. The results demonstrate that the operational and structural content consolidated in DIG Part IV persists under the multidimensional extension of the framework. Directional asymmetries and null projections are observed and are consistent with the tensorial formulation of information geometry in dimensions greater than one. All results reported in this work are fully reproducible from the accompanying public dataset without additional assumptions.

Preprint: This work is a preprint, has not undergone peer review, and is made publicly available to establish a public scientific record. This work formulates the Dynamical Information Geometry (DIG) framework in spatial dimension d > 1. Dynamical Information Geometry assigns an effective, state-dependent geometry to quantum many-body systems. Earlier work focused on the one-dimensional setting, where the structure of the framework can be developed in its simplest and most transparent form. This manuscript states the multidimensional formulation of DIG explicitly. In dimensions higher than one, information-induced geometry is inherently multidirectional and cannot be reduced to a single scalar quantity associated with a preferred coordinate. Directionality and projection therefore enter as intrinsic structural aspects of the framework. The presentation is theoretical and structural in nature. It fixes the multidimensional formulation of Dynamical Information Geometry at the level of the framework itself and is not tied to particular realizations, implementations, or test scenarios.

Preprint: This work is a preprint, has not undergone peer review, and is made publicly available to establish a public scientific record. This work presents a strictly structural analysis of directional Twin-Sign outcomes reported in Dynamical Information Geometry (DIG) Part VII. It derives minimal response-space implications from categorical PASS/FAIL classifications under fixed audit logic, without introducing new experiments, protocols, observables, or interpretive rules. Dynamical Information Geometry assigns an effective, state-dependent information geometry to quantum many-body dynamics via the curvature of coarse-grained mutual-information profiles. Earlier work introduced the theoretical framework (Part I), provided numerical evidence for sign-sensitive refraction effects (Part II), validated a minimal operational consequence on quantum hardware (Part III), established regime structure and operational necessity (Part IV), and formulated the intrinsic multidimensional (tensorial) nature of information geometry (Part V). Subsequent work reported experimental two-dimensional Twin-Sign validation under fixed audit and regime constraints (Part VII). The present work occupies a strictly consolidating and structural position within the DIG series. It does not perform new experiments, reanalyze raw measurement data, or extend the intervention space. Instead, it analyzes what minimal response-space structure is logically implied by the directional Twin-Sign outcome patterns already reported in DIG Part VII. Specifically, the work shows that simultaneous Twin-Sign PASS outcomes along two non-collinear projection directions necessitate the existence of a multidimensional response subspace. One-dimensional Twin-Sign behavior is identified as a degenerate projection of this structure. The analysis relies solely on linear independence and audit-fixed PASS/FAIL classifications and halts explicitly prior to any geometrical, dynamical, or ontological interpretation. No claim is made regarding the full dimensionality, geometry, dynamics, or reconstructability of the underlying response space. The structural necessity identified here is consistent with the DIG No-Derivation Claim: it does not enable reconstruction, dynamical inference, or ontological identification of internal response structures. All conclusions reported in this work are fully reproducible from the categorical Twin-Sign outcomes documented in DIG Part VII, using the publicly available dataset and analysis scripts provided therein, without additional assumptions.

Preprint: This work is a preprint, has not undergone peer review, and is made publicly available to establish a public scientific record. This publication presents a hardware validation of a minimal, sign-based operational consequence of the Dynamical Information Geometry (DIG) framework on real quantum devices. The work introduces no new theory and no numerical modeling. Instead, it tests a single operational hypothesis (OD-DIG-H1) on heterogeneous quantum hardware platforms, including IBM Quantum and AWS Braket (IonQ). The operational quantity tested is the sign of the leakage differenceΔLeak = Leak_LENS − Leak_CTRL,with leakage defined as Leak = 1 − P(b_ref). The reference bitstring is defined per run as b_ref = mode(CTRL), ensuring a hardware-agnostic reference choice. For all included hardware runs, the observed sign of ΔLeak is positive under the stated operational definition. The analysis is deliberately restricted to sign-only reporting and excludes fitting procedures, noise mitigation, or quantitative cross-platform comparisons. The results are supported by a publicly available, immutable hardware dataset archived on Zenodo.
