SCIENTIFIC-STATUS NOTICE This paper compares three already published quantum-materials studies through TSTOEAO. The reported coherence gains, encapsulation-epitaxy results, oxide-moiré reconstruction, and electromechanical observations are conventional experimental findings. The TSTOEAO contribution is a proposed cross-system taxonomy of boundary function, a comparative Relational Ledger, and a future prediction architecture. No claim is made that these retrospective studies confirm TSTOEAO, establish new fundamental physics, or prove a universal boundary law.

COMPACT PRINCIPLE An interface is not defined only by where it is. Its operative identity is determined by what it suppresses, what it enables, what it reorganizes, what it preserves, and what it carries forward.

Abstract

Interfaces are commonly treated as geometric locations between materials. That description is necessary but incomplete. In quantum materials and devices, an interface may reduce loss, enable formation, reorganize interior structure, preserve a fragile state, or remain as a persistent carrier of later physical conditions. These functions are not interchangeable, and they cannot be inferred from spatial location alone.

This paper develops a comparative TSTOEAO framework from three published systems. In tantalum-on-silicon transmon qubits, a changed material stack reduces bulk-substrate loss and supports millisecond-scale lifetimes and high gate fidelity without changing the basic two-dimensional transmon architecture. In encapsulation epitaxy, a predeposited graphene or hexagonal-boron-nitride layer both templates large-area monolayer niobium diselenide growth beneath it and protects the resulting film from ambient degradation. In chemically bonded twisted sodium-niobate membranes, the imposed interfacial relation is associated with distributed lattice rotation, conversion from a mixed-phase membrane state to a single-phase twisted-bilayer state, altered ferroelectric domain configuration, and twist-dependent electromechanical modulation.

The comparison yields a Boundary Functional Taxonomy. A suppressive or gate boundary weakens destructive routes; a generative boundary enables or selects formation routes; a reconstructive boundary propagates an interfacial relation into interior organization; a protective boundary preserves an existing state; a persistent boundary remains in the later Encoded Equilibrium; and a multifunction boundary performs more than one typed role. The paper proposes the Boundary Functional Transformation Principle: the operative identity of a boundary is specified by its typed effects on route admissibility, route weighting, ordered transformation, interior or persistent state, receiver access, cost, and subsequent architecture.

A comparative Minimum Sufficient Relational Ledger is constructed for the three systems. It records the prepared state, temporal order, boundary intervention, route portfolio, domain-valid dynamics, receivers, cost and export, persistence, comparator, and falsifier. Candidate role-specific observables are introduced for suppression, generation, reconstruction reach, protection, and persistent carryover. These are scaffolds, not universal constants. A distinct TSTOEAO prediction will require one prospectively derived difference from the strongest conventional comparator, a fixed receiver consequence, and a result that can fail without adding hidden interface accounts after the outcome.

The strongest conclusion is methodological. “Interface” is too broad to function as a scientific explanation. A useful boundary theory must specify what the interface does, when it does it, through which physical route, how deeply the effect propagates, what remains afterward, and what a fixed receiver records.

Central propositions

1. A physical interface is not fully classified by composition or location; it must also be classified by operative function.

2. A boundary may suppress destructive routes, generate formation routes, reconstruct interior organization, protect a formed state, persist into later architecture, or perform several of these roles together.

3. The same nominal material boundary can perform different functions when its temporal placement, coupling, or physical history differs.

4. A boundary effect must be traced to a declared physical mechanism, account, route, receiver, or cost; “the interface mattered” is not a sufficient explanation.

5. Suppression, generation, reconstruction, protection, and persistence require different receiver evidence and different falsifiers.

6. A retrospective fit to published materials results is calibration, not prospective confirmation.

7. A cross-system taxonomy becomes scientifically useful only when it compresses description without erasing domain-specific mechanisms and supports a locked prediction that a conventional comparator does not already make.

8. The next scientific obligation is to choose one boundary function, derive one quantitative receiver consequence, and preregister its sign, range, comparator, and failure condition.

1. Purpose, scope, and claim classification

The purpose of this paper is to determine whether three physically different interface studies can be organized by one comparative boundary-function architecture without erasing the conventional mechanisms that make each system work. The paper does not ask whether all interfaces matter. It asks what kinds of work interfaces perform, how those functions can be distinguished, and what evidence would be required to move from retrospective classification to prospective prediction.

The three calibration systems were selected because they occupy different positions in the physical sequence. The tantalum-on-silicon transmon concerns persistence of an already fabricated quantum state under a changed loss environment. Encapsulation epitaxy concerns formation of a material inside a boundary that exists before nucleation. Twisted sodium-niobate bilayers concern propagation of an imposed interfacial relation into the material interior after chemically bonded assembly.

1.1 Claim classification

CLAIM CLASSIFICATION Comparative retrospective calibration and proposed cross-system scientific formalization. The experimental results are conventional science. The Boundary Functional Taxonomy, Boundary Functional Transformation Principle, comparative Ledger, role-specific observables, and future prediction modules are proposed TSTOEAO formalizations.

1.2 What this paper establishes

• The word interface combines several physically distinct functions that should be separated.

• The three selected systems support a comparative classification of gate, generator, reconstructor, protector, and persistent carrier.

• Temporal placement and ordered physical history are part of boundary identity.

• A cross-system Minimum Sufficient Relational Ledger can be written without treating “interface effects” as an unlimited residual account.

• Each boundary function requires a different receiver and a different local falsifier.

• The taxonomy identifies prospective branches, but none of the already published outcomes can count as a TSTOEAO prediction.

1.3 What this paper does not establish

• That TSTOEAO predicted any of the three reported studies before publication.

• That conventional loss modeling, epitaxy, elasticity, phase-field theory, or twistronics are incomplete merely because TSTOEAO supplies a broader vocabulary.

• That every interface belongs to only one functional class.

• That a favorable boundary in one material will have the same direction or scale in another.

• That the proposed role-specific observables possess universal thresholds.

• That an interface exerts a new force, violates conservation, or proves the TSTOEAO substrate.

• That the three cases alone establish a universal law of quantum materials.

2. Source basis and evidence hierarchy

The principal external sources are the Nature report of millisecond-lifetime tantalum-on-silicon transmons [1], the Nature report of encapsulation epitaxy for air-stable monolayer NbSe₂ [2], and the ACS Nano report of large-area chemically bonded oxide moiré superlattices [3]. Institutional accounts from MIT and North Carolina State are used only to clarify the reported process sequence and author interpretation [4,5].

The principal TSTOEAO sources are TSTOEAO IV, Pathways, Boundaries, and Phases, TSTOEAO Empirical Core v1.0.0, Before the Outcome, The Relational Ledger, The Minimum Sufficient Relational Ledger, and The Boundary Before the Material [15–21]. These sources provide the project’s terms for conditioned realization, boundary, route, receiver, cost, history, minimum sufficiency, distinctness, and preregistration.

2.1 Established TSTOEAO doctrine

V is Value or realized outcome, E is Energy or Opportunity, and Y is Encoded Equilibrium. The multiplication sign is not assumed to be ordinary scalar multiplication in every domain. Its minimum empirical meaning is conditioned realization: comparable available capacity may produce different registered outcomes under different independently specified architectures.

Within the present paper, Y includes the material stack, interface geometry, sequence, coupling, admissible routes, route weights, transformation rules, receiver geometry, cost channels, and persistent history. The boundary is therefore neither scenery nor a universal causal substitute. It is one typed component of the physical architecture.

2.2 Proposed scientific formalization

The boundary-function categories, comparative function signature, cross-system Ledger, candidate role-specific observables, and prediction modules below are proposed formalizations. They are not retroactively attributed as exact equations already contained in the earlier books.

2.3 Conventional knowledge

Dielectric participation, two-level-system loss, Josephson-junction decoherence, superconducting-circuit control, adsorption and diffusion, nucleation and epitaxy, oxidation, interfacial bonding, elasticity, shear accommodation, structural phase transition, ferroelectric domains, and piezoresponse belong to established physics and materials science. A valid TSTOEAO account must preserve those mechanisms and compare against their strongest quantitative forms.

2.4 Evidence ladder

3. Why “interface” is not one scientific function

An interface is a spatial relation. A boundary function is a physical role. The two should not be collapsed. The same spatial interface can change function over time, and different interfaces can perform the same class of work through different mechanisms.

For example, a metal–substrate interface can contribute to dielectric loss, a predeposited cap–substrate gap can confine precursor transport, and a chemically bonded twisted interface can transmit shear and reconstruct lattice organization. Calling all three “interface effects” preserves location while losing causal type.

The minimum scientific question is therefore not merely “Is an interface present?” It is:

FUNCTIONAL QUESTION Which registered routes does the interface admit, suppress, weight, transform, propagate, preserve, or make visible—and during which part of the ordered physical history?

Figure 1. Three principal operative roles compared in this paper. These are functional classifications, not claims that each real interface performs only one role.

3.1 Spatial identity versus operative identity

Spatial identity specifies where two regions meet. Operative identity specifies what changes because they meet under a declared composition, coupling, sequence, and receiver. A functional classification requires a measured route-specific difference or receiver-accessible consequence. Presence alone is insufficient.

3.2 Function is time-indexed

The NbSe₂ encapsulation layer is generative during growth and protective afterward. The sodium-niobate interface is assembled, chemically bonded, and then becomes a source of distributed reconstruction. A tantalum–silicon material stack affects the loss environment during later quantum operation. Boundary identity must therefore include temporal position.

3.3 Function is directional

An interface may act from boundary to interior, interior to boundary, or bidirectionally. Loss can flow outward from a stored quantum mode; precursors can enter and move inside a confined interface; stress and rotation can propagate away from a bonded plane. A boundary account that lacks directionality is incomplete.

4. Case I — The interface as gate: tantalum on silicon

Bland and colleagues reported two-dimensional transmon qubits fabricated from tantalum on high-resistivity silicon [1]. The central conventional result was not a new qubit architecture. Replacing sapphire with silicon reduced bulk-substrate loss, while improved materials processing and lower-contamination junction fabrication reduced additional decoherence channels. Across 45 qubits, the reported time-averaged quality factor was 9.7 × 10⁶; the best device reached a lifetime T₁ of 1.68 ms, and single-qubit gates reached 99.994% fidelity [1].

4.1 The conventional loss architecture

A transmon stores quantum excitation in an engineered electromagnetic mode. The registered lifetime is limited by the total loss rate. In the simplest additive budget, independently modeled channels contribute to the observed decay rate:

The experiment’s significance is that suppressing one large account exposes the next limiting account. Reduced bulk and surface loss made junction-related decoherence observable. That is exactly the behavior expected from a finite Ledger: removing one dominant route does not eliminate the accounting burden; it reveals the remaining routes.

4.2 Gate or suppressive function

The term gate is used here in a functional, not transistor-specific, sense. The changed material architecture reduces the accessibility or weight of destructive relaxation routes. It does not forbid all loss, and it does not create coherence from nothing. It changes the hazard portfolio through which stored quantum energy and phase information can be degraded.

A suppressive classification requires a preregistered loss account, a validated receiver, and a nonzero reduction exceeding the equivalence margin δΓ. Longer T₁ by itself does not identify which channel changed.

4.3 Minimum ledger for the gate function

Ledger field	Minimum content
Prepared state	Qubit geometry, frequency, capacitor and junction design, material stack, fabrication history.
Boundary intervention	Substrate identity, metal–substrate interface, surface oxide, trenching, contamination, junction process.
Routes	Bulk dielectric loss, surface loss, junction loss, radiation, quasiparticles, drive/readout coupling.
Receivers	T₁, Ramsey and echo coherence, quality factor, randomized benchmarking, materials microscopy and spectroscopy.
Cost / export	Energy relaxation, dephasing, heat, quasiparticle generation, fabrication complexity, yield.
Comparator	Participation-ratio and materials-loss model for the same architecture.
Falsifier	Predicted route reduction absent after verified material intervention and adequate receiver sensitivity.

4.4 Claim limit

This case is a clear retrospective calibration of channel-selective expression. It does not establish a TSTOEAO-specific loss law. Conventional participation-ratio modeling already predicts that changing bulk and surface dielectric loss changes coherence. A distinct TSTOEAO contribution would require a prospectively derived cross-channel relation, residual, or intervention response that the strongest loss model does not already contain.

5. Case II — The interface as generator: encapsulation epitaxy

Zheng and colleagues reported “encapsulation epitaxy,” in which graphene or hexagonal boron nitride is deposited on a three-dimensional substrate before monolayer NbSe₂ growth [2]. The two-dimensional layer simultaneously serves as a template for growth underneath it at the encapsulation–substrate interface and as a protective cap after formation. The reported films exceed one inch in scale, remain air-stable, show superconductivity near 1 K and a charge-density-wave transition near 177 K, and support oxidation-free transfer, superconducting edge contacts, and measured sheet kinetic inductance near 0.7 nH per square [2].

5.1 Boundary-first formation

This system differs from a later coating because the boundary is already active when precursor entry, retention, lateral transport, nucleation, and coalescence occur. The material does not first form in one world and then receive protection. It forms inside the protected and transport-governing world.

The noncommutativity expresses path dependence. Oxidation, contamination, nucleation density, defect formation, layer selection, and interface quality can change before a later cap is applied. Matching final composition does not erase the route history.

5.2 Generative and protective roles

The interface is generative during formation because it changes the route portfolio through which the target material becomes expressed. It is protective afterward because the same cap remains and attenuates ambient degradation. The two functions must be measured separately: good growth does not prove good environmental protection, and good protection of a postgrown film does not prove generative function.

5.3 Minimum ledger for the generator function

Ledger field	Minimum content
Prepared state	Substrate, predeposited encapsulant, gap distribution, adhesion, temperature, pressure, precursor chemistry.
Boundary intervention	Pre-growth encapsulation–substrate interface and temporal sequence.
Routes	Entry, retention, diffusion, nucleation, lateral spread, multilayer growth, parasitic reaction, oxidation, transfer, contact.
Receivers	Microscopy, diffraction, spectroscopy, oxidation assay, transport, kinetic inductance, fabrication yield.
Cost / export	Precursor waste, thermal budget, defects, by-products, oxidation, transfer damage, contact burden.
Comparator	Interface chemistry, adsorption/desorption, diffusion, nucleation, growth, oxidation, and device model.
Falsifier	Verified boundary-first intervention produces no registered route or outcome difference beyond equivalence margins.

5.4 Claim limit

The case supports the Generative Boundary Principle as retrospective calibration. It does not show that boundary-first synthesis always improves material quality or that TSTOEAO adds a new microscopic mechanism. The strongest next test is a matched sequence-reversal or interfacial-gap experiment with locked route endpoints and a conventional kinetic comparator.

6. Case III — The interface as reconstructor: chemically bonded oxide moiré superlattices

Ghanbari and colleagues reported a deterministic method for fabricating large-area, high-crystallinity oxide moiré superlattices from twisted sodium-niobate membranes with strong chemical bonding [3]. The approach achieves nominal twist angles down to 0.1°, subdegree accuracy, and contiguous lateral dimensions approaching the millimeter scale. Synchrotron three-dimensional reciprocal-space mapping showed a single-phase twisted-bilayer state in contrast to the mixed-phase single-layer membranes before assembly. The structural signatures were consistent with gradual lattice rotation distributed through the thickness, potentially accommodating interfacial shear strain, and were correlated with twist-dependent nanoscale electromechanical modulation [3].

6.1 Reconstruction beyond the plane

The imposed relation is initially interfacial: two crystalline membranes meet at a controlled twist angle and are chemically bonded by annealing. The measured response is not confined to a geometrical mismatch at one plane. The boundary relation is associated with a distributed structural response, phase reorganization, and altered ferroelectric domain configuration.

This motivates a reconstructive classification: a boundary is reconstructive when an independently controlled interfacial relation propagates into the organization of the adjoining material, producing a measured interior-state difference rather than merely a local contact effect.

Here q(z) is a preregistered structural, phase, strain, polarization, or domain field, D is a declared distance or contrast measure, and δR is the equivalence margin. The criterion does not assume one universal reconstruction mechanism.

6.2 Strong coupling and persistent history

The annealed chemical bond converts the assembled twist relation into a persistent physical state. That state remains in the later architecture and conditions subsequent structural and electromechanical behavior. The interface is therefore both reconstructive and persistent.

6.3 Minimum ledger for the reconstructor function

Ledger field	Minimum content
Prepared state	Membrane phase mixture, thickness, crystallinity, surface state, marker geometry, support.
Boundary intervention	Twist angle, alignment uncertainty, contact condition, annealing protocol, chemical bond formation.
Routes	Elastic accommodation, shear transfer, lattice rotation, phase conversion, domain reorganization, defect and delamination routes.
Receivers	Synchrotron 3D reciprocal-space maps, microscopy, phase fraction, domain mapping, piezoresponse-force microscopy.
Cost / export	Elastic strain, defects, thermal budget, interfacial energy, domain-wall burden, damage or delamination.
Comparator	Elasticity, phase-field, crystallographic, interfacial bonding, and moiré reconstruction model.
Falsifier	Verified twist/bond intervention fails to produce the locked interior structural or domain consequence.

6.4 Claim limit

The study does not yet establish a general electronic or device-performance law for twisted NaNbO₃. The reported electromechanical modulation is correlated with the reconstructed state, while the full consequences for material properties remain under investigation. TSTOEAO must not convert that open question into a claimed prediction after the fact.

7. Boundary Functional Taxonomy

The comparative cases support a role taxonomy. The categories are neither exclusive nor exhaustive. They are intended to prevent the word boundary from absorbing several distinct causal functions.

Functional class	Operational definition	Minimum evidence
Suppressive / gate	Reduces the admissibility, weight, or hazard of a preregistered destructive route.	Measured route reduction or outcome improvement tied to the declared channel.
Generative	Changes the route portfolio through which a target form nucleates, grows, stabilizes, or becomes accessible.	Boundary present during formation plus route-specific or formation-outcome difference.
Reconstructive	Propagates an interfacial relation into measurable interior organization.	Registered interior field, phase, domain, or structural contrast beyond the interface.
Protective	Reduces degradation of an already formed state.	Matched exposure with a registered survival or degradation endpoint.
Persistent carrier	Remains physically present and contributes to later Encoded Equilibrium.	Intervention on the preserved carrier changes a later registered outcome.
Multifunction	Performs two or more typed roles that remain separately identifiable.	Each claimed role passes its own receiver and falsifier.
Coincident	Present but with no demonstrated role in the registered purpose.	No role-specific consequence established.

7.1 Functional classes are not moral rankings

Generative does not mean beneficial, and suppressive does not mean desirable. A boundary can generate a parasitic phase, suppress a productive channel, reconstruct a material into a less useful state, or preserve damage. The sign must be derived for the system.

7.2 Multifunction does not mean vague

A multifunction boundary is not an excuse to label every observed effect as one interface role. The NbSe₂ cap can be generative and protective because those functions occur at different phases and can be assigned different routes and receivers. Each function must remain independently testable.

8. Boundary Functional Transformation Principle

PROPOSED PRINCIPLE A physical boundary is not operationally defined solely by spatial separation or material composition. Its scientific identity is specified by the typed transformations it produces in route admissibility, route weighting, ordered dynamics, interior or persistent state, receiver access, cost location, and subsequent Encoded Equilibrium.

8.1 Boundary transformation object

B is the physical boundary, τ is the ordered time structure, A the registered route set, W route weights or rates, T transformations, M receivers, K costs and exports, H persistent history, V registered outcomes, and Z evidentiary status. This is a model object, not a new physical field.

8.2 Boundary-induced update

IB is the boundary intervention and I0 the matched comparator intervention. The difference must be evaluated through registered accounts rather than a retrospective global judgment that the interface mattered.

Figure 2. Proposed Boundary Functional Transformation Architecture. The classification follows the ordered physical changes from intervention to later Encoded Equilibrium.

8.3 Functional role tests

A boundary receives a functional label only if the corresponding map is non-null under the declared receiver and uncertainty. For example, gate status requires a loss-route change, generative status requires a formation-route change, and reconstructive status requires an interior-state change. A favorable final outcome alone may be insufficient to distinguish these roles.

9. Sequence, directionality, and noncommutativity

Boundary functions are sequence-sensitive. A cap applied after oxidation begins is not equivalent to a cap present before nucleation. A twist relation before chemical bonding is not equivalent to the bonded reconstructed state after annealing. A substrate chosen before qubit fabrication changes every later field-participation calculation.

The update order is part of the model. In path-dependent systems, operations generally do not commute. The difference can remain even when the final ingredient list appears similar.

9.1 Boundary-to-interior propagation

The reconstructive case requires a depth-resolved account. Let z measure distance from the interface. A reconstruction profile q(z) must specify how the imposed boundary relation decays, rotates, changes phase, or alters domains through the material. The range and form are conventional, system-dependent quantities—not assumed universal.

9.2 Interior-to-boundary export

The gate case emphasizes the opposite direction. Stored quantum energy can be exported through bulk, surface, junction, radiative, or quasiparticle routes. A boundary can change those export rates. The full architecture is therefore relational and directional rather than purely enclosing.

9.3 Persistent recursion

A formed cap, bonded twist interface, defect population, residual strain field, or fabrication history can remain as a physical carrier that changes later outcomes. Persistence must be verified through intervention on the carrier, not inferred merely because history exists.

10. Boundary-function signatures

A cross-system comparison requires a typed signature rather than one scalar “boundary strength.” The proposed signature is:

𝒮B is suppressive function, 𝒢B generative function, ℛB reconstructive function, 𝒫B protective function, and ℋB persistent carryover. The components may be functions, parameters, or registered contrasts with different units. They must not be added into a universal score without a justified conversion model.

System	Dominant signature	Secondary signature	Status
Ta / Si transmon	𝒮B: reduction of selected loss accounts	ℋB: fabrication and materials history persists into operation	Clear retrospective calibration compatibility.
Encapsulation epitaxy	𝒢B: formation route enabled or strongly reweighted	𝒫B and ℋB: cap protects and remains in later device architecture	Clear retrospective calibration compatibility.
Twisted NaNbO₃ bilayer	ℛB: interfacial relation propagates into interior structure	ℋB: chemically bonded twist remains as later architecture	Clear retrospective calibration compatibility.

10.1 Signature equivalence and distinction

Two interfaces made from different materials may belong to the same functional class if they produce equivalent route-level transformations under a registered criterion. Conversely, the same nominal material interface may have different signatures under different sequence, pressure, temperature, bonding, or receiver conditions.

10.2 No universal ordering

The taxonomy does not imply that gate precedes generator or that reconstructor is a deeper class. These are orthogonal roles. A system can be strongly suppressive and weakly protective, or highly reconstructive while offering no useful persistence under operation.

11. Comparative Minimum Sufficient Relational Ledger

The comparative Ledger is purpose-relative. It does not attempt to contain every property of every material. It retains only the accounts necessary to distinguish the registered boundary function, close the relevant balances, calculate the receiver outcome, locate cost and history, compare against the strongest conventional model, and preserve a local falsifier.

Figure 3. Comparative boundary-function ledger. Each system preserves its domain-specific mechanisms while sharing a common typed accounting architecture.

Field	Ta / Si transmon	Encapsulation epitaxy	Twisted NaNbO₃
C — boundary	Chip, package, substrate, metal, junction, control/readout.	Reactor, cap–substrate interface, ambient, transfer, device.	Membranes, bonded interface, support, anneal, measurement volume.
τ — sequence	Fabrication → cooldown → preparation → control → decay/readout.	Cap deposition → precursor entry → growth → handling → transfer → device.	Membrane preparation → twist assembly → anneal → reconstruction → measurement.
E — available capacity	Stored excitation and control capacity.	Precursor, thermal, and chemical process capacity.	Elastic, thermal, interfacial, ferroic, and assembly capacity.

N — comparator	Participation-ratio and decoherence model.	Growth, diffusion, nucleation, oxidation, fabrication model.	Elasticity, crystallography, phase-field, bonding, moiré model.
F — falsifier	Locked route reduction absent.	Locked formation/protection route difference absent.	Locked interior reconstruction absent or wrong-directed.

11.1 Minimum-sufficiency rule

An account is retained only when its removal breaks closure, role discrimination, predictive sufficiency, practical identifiability, cost location, historical carryover, or falsifiability for the registered purpose. “All other interface effects” is not a valid confirmatory account.

11.2 Observationally equivalent ledgers

Different microscopic ledgers may produce the same registered distribution under the available interventions. In that case the experiment identifies an equivalence class, not one uniquely true hidden structure. A new intervention must be designed to separate the competing ledgers.

12. Receiver architecture and object maps

Each case constructs a different receiver-conditioned object. The transmon receiver constructs a lifetime, coherence, and gate-error object. Encapsulation epitaxy constructs structural, chemical, superconducting, and device-integration objects. Oxide twistronics constructs reciprocal-space, phase, domain, and electromechanical objects.

12.1 Multi-receiver coherence

A functional classification should not rest on one favorable receiver when the claimed object spans several channels. Longer T₁ does not by itself identify bulk versus surface loss. Continuous monolayer coverage does not prove preserved superconductivity or device survival. A single-phase diffraction signature does not by itself specify the ferroelectric domain or electromechanical consequence.

The object map 𝒪B is a preregistered receiver set. Cross-channel relations must be source-consistent and fixed before confirmatory access.

12.2 Null discipline

A null in one receiver is not automatically a null in every physical account. But neither can a missed signal become evidence for an unspecified hidden interface effect. Cancellation, screening, insufficient sensitivity, or unmeasured cost must be prospectively modeled and independently tested.

13. Cost, export, and persistence

Boundary engineering redistributes cost; it does not remove physical accounting. Longer coherence may require cleaner fabrication, lower contamination, added process control, and stricter materials selection. Encapsulation epitaxy may reduce oxidation while adding cap preparation, thermal budget, transfer complexity, and interface-control demands. Oxide reconstruction may create useful structure while storing elastic energy, forming defects, or changing domain-wall burden.

The cost vector remains typed. It should not be collapsed into one scalar without a valid conversion model.

13.1 No disappearance

Energy lost from a qubit must enter a physical channel. Precursors not incorporated into a film must desorb, exhaust, deposit elsewhere, react, or remain. Interfacial strain must be stored, redistributed, relaxed, defected, or exported. The Ledger requires each relevant balance to close within uncertainty or cross a registered boundary.

13.2 Persistence is an intervention claim

A cap, bond, strain field, domain structure, oxide, or contamination record may persist. EC-4 relevance becomes a direct test only when the preserved carrier is modified, removed, reset, or otherwise intervened upon and a later outcome changes through the declared route.

14. Empirical Core traceability

Empirical proposition	Comparative role	Status
EC-1: Conditioned Expression	Comparable capacity produces different registered outcomes under different independently specified material and interface architectures.	Clear retrospective calibration compatibility in all three cases; no prospective confirmation.
EC-2: Channel-Selective Expression	Loss routes, formation routes, reconstruction routes, receiver access, and cost locations differ with the boundary architecture.	Primary calibration proposition; route-specific measures required.
EC-3: Structured Response	Applicable only where a declared gradient, correction or failed correction, cost prediction, and equilibrium class are registered.	Not automatically tested by the three reported studies. Future active-control or relaxation modules possible.
EC-4: Recursive Boundary Construction	Fabrication, cap, bond, strain, domains, and other persistent carriers may contribute to later Y.	Relevant; direct test requires intervention on the preserved carrier and a later consequence.

14.1 Governing discipline

SCIENTIFIC DISCIPLINE A theory cannot claim courage before an experiment and become metaphor after the result. These studies may calibrate variables and suggest tests, but their already known outcomes cannot count as TSTOEAO predictions.

15. Distinctness and conventional comparators

The strongest comparator is never “interfaces do not matter.” Each domain already possesses sophisticated interface science. The transmon comparator includes dielectric participation, two-level systems, junction and quasiparticle loss, radiation, and control coupling. The epitaxy comparator includes chemistry, adsorption, diffusion, nucleation, oxidation, strain, and fabrication. The oxide comparator includes bonding, elasticity, crystallography, phase-field response, and moiré reconstruction.

15.1 Complete model object

15.2 Distinctness Condition

If the prepared state, boundary, intervention, parameters, constraints, update law, and receiver are unchanged, TSTOEAO cannot make a different prediction merely by calling the interface a gate, generator, or reconstructor. New terminology is not new physics.

15.3 What would count as distinct

• A prospectively derived route that the comparator excludes or weights differently.

• A cross-channel constraint linking two receivers more tightly than the comparator.

• A fixed reconstruction profile, threshold, sign, or scaling law not present in the conventional model.

• A cost-location or persistent-history term that survives all registered controls and cannot be absorbed by conventional parameters.

• A nonzero held-out receiver consequence with a locked local falsifier.

16. Comparative prediction architecture

The statements below are prediction families. They become confirmatory only when material, intervention, sign, scale or interval, receiver, quality gates, comparator, and falsifier are version-locked before outcome access.

16.1 BF-1 — Functional-role separation

An intervention designed to reduce a loss route should not automatically be classified as generative; an intervention that supports formation should not automatically be classified as protective. Matched experiments should separate the receiver consequences associated with each role.

16.2 BF-2 — Sequence noncommutativity

The effect must be predicted for a declared sequence pair. The result fails if the outputs are equivalent within the registered margin after sequence fidelity is verified.

16.3 BF-3 — Route redistribution

When a boundary is classified as a gate, at least one declared destructive route must decrease. When classified as a generator, at least one formation route must increase or become admissible. The route endpoint must be measured independently of the final outcome whenever possible.

16.4 BF-4 — Reconstruction reach

A reconstructive interface should produce a locked depth-, thickness-, or distance-dependent interior contrast. A purely local interface change cannot be retrospectively relabeled as distributed reconstruction.

16.5 BF-5 — Multi-receiver coherence

A preregistered relation should connect the route change to more than one receiver. For example, a growth route may predict coverage and device yield; a reconstruction route may predict diffraction and domain response. One favorable channel cannot replace the joint object map.

16.6 BF-6 — Persistent-carrier intervention

Modify or remove the declared persistent carrier. If the later outcome does not change within the predicted sensitivity, the registered carryover claim fails.

16.7 BF-7 — Cross-system functional transfer

A functional rule may transfer across materials only when the meaning of route, receiver, cost, and boundary role remains fixed. If every new system requires redefining the role after the outcome, the taxonomy has not achieved transferable scientific compression.

17. Candidate role-specific observables

The following quantities are candidate scaffolds. They are not universal laws and should be replaced by stronger domain-valid measures where available.

17.1 Suppression contrast

SB is positive when the registered loss rate decreases, zero at equivalence, and negative when the boundary worsens the route. The loss channel and comparator must be specified.

17.2 Generative route fraction

The fluxes must be defined on a common basis. The measure does not assume the target route should always dominate; it only records the selected competition.

17.3 Reconstruction reach

RB is a normalized interior contrast over thickness h. qref must be physically justified. The profile can represent lattice rotation, strain, phase fraction, polarization, or another registered field.

17.4 Protective survival

S(t) is a declared survival or retained-property function under matched exposure. A protective claim requires a post-formation endpoint and does not establish generative function.

17.5 Persistent carryover contrast

The intact and removed conditions require a sham intervention and verification that removal did not create a new uncontrolled boundary. Vscale is preregistered.

17.6 No composite score by default

The role-specific observables must not be averaged into one “interface value” unless a domain-valid conversion and weighting model is established. The taxonomy is intended to preserve function, not erase it through scoring.

18. Falsification, weakening, and non-rescue rules

18.1 Local failure

• The boundary intervention is independently verified, but the preregistered route consequence is absent.

• The locked sign, threshold, reconstruction profile, survival contrast, or carryover effect is reversed or outside the allowed interval.

• A claimed gate improves the final outcome without reducing the registered destructive route.

• A claimed generator is present before formation but produces no measured formation-route difference.

• A claimed reconstructor produces only an interfacial-local change when distributed interior response was predicted.

• A claimed persistent carrier can be removed without the predicted later consequence.

• The relevant cost or export cannot be closed within uncertainty.

• A simpler conventional model predicts the held-out data equally or better without the TSTOEAO-specific term.

18.2 Compatible but non-distinct outcome

A result may fit the boundary-function architecture and still provide no distinct support for TSTOEAO. When the strongest conventional model predicts the same receiver distribution, the correct classification is Compatible but Non-Distinct.

18.3 Prohibited rescue statements

• The real interface function was an unmeasured account added after failure.

• The missing effect moved into an unspecified cost channel outside the registered boundary.

• The receiver could not see the effect although receiver sensitivity and exclusions already passed.

• The opposite sign is another expression of the same prediction.

• The interface acted through the substrate without a measurable intermediate variable.

• Every improved quantum material supports TSTOEAO because every material has an interface.

• A local null proves hidden participation elsewhere.

18.4 Framework-level weakening

• The taxonomy cannot be applied without redefining its categories after each outcome.

• Boundary-function labels add no predictive, diagnostic, or design value beyond established domain language.

• The comparative Ledger cannot be made finite or identifiable.

• Different incompatible ledgers fit all registered interventions and no discriminating test can be designed.

• Cross-system transfer repeatedly fails under fixed definitions.

• No prospectively distinct boundary-function term survives independent replication.

19. Research program

19.1 Stage One — Build machine-readable case ledgers

Encode the three published systems using the cross-system MRLR. Mark every field as prepared, measured, calibrated, inferred, simulated, bounded, excluded, unresolved, or speculative. Preserve primary-source provenance.

19.2 Stage Two — Reproduce conventional physics

Reproduce the reported trends using the strongest domain-valid models without any TSTOEAO-specific parameter. The purpose is to identify what the taxonomy organizes, not to claim conventional mechanisms are absent.

19.3 Stage Three — Test taxonomy stability

Apply the same functional definitions to additional systems without changing their meaning. Report borderline and failed classifications. Determine whether the taxonomy compresses evidence or merely renames domain terms.

19.4 Stage Four — Select one branch

Choose one role only for confirmatory development: loss-route suppression, boundary-first generation, interior reconstruction, protection, or persistent carryover. Do not fit all roles simultaneously to the same confirmatory dataset.

19.5 Stage Five — Derive one distinct observable

Specify the complete model object, identify exactly where the TSTOEAO model differs from the strongest comparator, and derive one nonzero receiver consequence. Fix units, normalization, sign, interval, intervention, quality gates, and local falsifier before accessing confirmatory data.

19.6 Preferred near-term branch

The oxide-reconstruction system offers a particularly clear boundary-to-interior branch because twist angle, bonding, thickness, phase fraction, lattice-rotation profile, domain configuration, and electromechanical response can be registered as separate accounts. Its scientific challenge is equally clear: elasticity, crystallography, and phase-field theory may already explain the observations. A TSTOEAO-distinct result would need a derived relation those models do not possess, not merely the expectation that twist changes structure.

20. Conclusion

The three systems show why “interface” is too broad to serve as a complete scientific explanation. In tantalum-on-silicon transmons, the material stack functions primarily as a gate that reduces selected routes of decoherence. In encapsulation epitaxy, the preexisting interface functions as a generator during formation and a protector afterward. In chemically bonded oxide moiré superlattices, the imposed twist relation functions as a reconstructor whose effect is expressed through distributed lattice response, phase reorganization, domain configuration, and electromechanical modulation.

These functions can coexist, but they should not be collapsed. A useful boundary account must state what is suppressed, what is admitted, what is transformed, how far the effect propagates, what receiver registers it, what cost is relocated, and what persists into the next architecture.

BOUNDARY FUNCTIONAL TRANSFORMATION PRINCIPLE The operative identity of a physical interface is determined by its typed consequences across an ordered relational account—not merely by its spatial location or material composition.

Within TSTOEAO, the comparative architecture can be expressed as:

A boundary changes route admissibility, weighting, or transformation; those changes produce registered outcomes, persistent states, and costs; and the physically preserved result contributes to the later Encoded Equilibrium. This is a coherent comparative framework, but it remains retrospective calibration until one boundary-function difference is derived and locked before the outcome.

The next paper should therefore not offer another broad claim that interfaces matter. It should choose one functional branch, write the conventional and TSTOEAO model objects side by side, derive one dimensionless receiver contrast, and let untouched data decide whether the proposed distinction is real.

DEEPEST CONCLUSION The interface is not merely the place where two materials meet. It can be the gate that protects a state, the world in which a material is allowed to form, or the relation that reorganizes matter from within.
