Why is the boundary defined at the AC interface u2014 what about internal processes?

Boundary-level accounting (Level 1) is evaluated at the complete device boundary, where all energy inputs and outputs are referenced as accounting quantities: P_in,boundary = P_load + P_losses + dE/dt. Internal processes u2014 regulated feedback path, BMS coordination, discharge dynamics u2014 operate at regime level (Level 2). Local ratios at regime level describe redistribution between sub-blocks; they do not redefine the boundary balance. Drawing the measurement boundary around a subsystem (such as Circuit A only) instead of the complete device produces a boundary-definition artifact, not a physics phenomenon.

Endurance Test — 1,000+ Hours of Empirical Answer

Boundary-level operation under sustained load. The architecture proves itself through measurement.

VENDOR.Max is an Armstrong-type nonlinear electrodynamic oscillator operating in a controlled discharge-resonant regime. This page documents the empirical answer to the central engineering question: does the regulated feedback path provide sufficient contribution within the boundary-accounted system to maintain the operating regime under sustained real-load conditions?

A prototype unit was evaluated under controlled laboratory conditions using a black-box boundary measurement protocol. Measurement boundaries were defined exclusively by external electrical interfaces — the ignition port for startup and the AC interface for operational boundary. Pre-commercial validation stage at TRL 5–6.

The prototype maintained a stable operating regime for more than 1,000 hours of cumulative runtime, including 532 hours of continuous operation at a fixed 4 kW load. Approximately 4 MWh of cumulative delivered energy was observed under validation-stage measurement at the AC interface, within calibration tolerance. No critical degradation was observed.

01 · Central Engineering Question · What This Test Answers

The Question. And the Empirical Answer.

Endurance testing is not a generic “how long the device runs” measurement. It is the empirical answer to a specific physical question posed by the architecture.

Central Engineering Question · Architecture-Specific

“Does the regulated feedback path (Circuit B) provide sufficient contribution within the boundary-accounted system to maintain the operating regime under sustained 4 kW load, while the load path simultaneously delivers rated power, across extended real-load conditions, after disconnection of the 0.015 Wh startup impulse at the ignition port?”

This question is documented in the architecture description (How It Works) and in the four-validation-bottlenecks engineering self-disclosure. The regulated feedback path operates at regime level — its function is to redistribute energy within the formed regime to maintain operating continuity. Whether this redistribution remains sufficient under sustained real load — within the boundary-accounted system — while the load path simultaneously delivers rated power, is the central engineering question.

At the complete device boundary (Level 1), classical energy conservation applies at all operational states: P_in,boundary = P_load + P_losses + dE/dt. At regime level (Level 2), the question is whether the regulated feedback path coordinates redistribution sufficiently for the regime to persist under sustained load extraction.

This page documents the empirical answer measured across 1,000+ hours of cumulative runtime, including a 532-hour sustained segment at 4 kW. The answer applies within the disclosed validation window and within the defined load-compatible operating envelope.

02 · Engineering Classification · Established Framework

This Is Established Engineering. Not New Physics.

The VENDOR.Max architecture belongs to a recognized engineering class that has been studied, published, and engineered for decades. The classification is supported by patent examiners, standard textbooks, and established conference frameworks.

Engineering Category

Pulse Power Generator on Spark Gaps

VENDOR.Max is classified as an Armstrong-type nonlinear electrodynamic oscillator operating in a controlled discharge-resonant regime — a sub-class of pulse power generators using spark-gap-based pulse formation. This engineering category exists in the literature for decades and is a recognized industrial topology.

Reference Frameworks

Established Conference & Literature

Standard reference frameworks for this engineering class:

IPC Classification · External Validation

Patent Examiner Classification

International Patent Classification (IPC) codes assigned by patent examiners during prosecution — not self-declared by the applicant:

H03K 3/537 (narrowest): pulse generation via storage element discharged through load via spark gap
H02M 3/00–3/335
H02M 7/00–7/06
H02P 13/00
H02J 7/00–7/50

Anchor · Established Engineering Class

The narrowest IPC code, H03K 3/537, literally describes the architecture: a storage element (capacitor bank) discharged through a load via a spark gap. This is a recognized engineering category, not a novel physical claim. The patent examiners’ classification serves as external validation that the architecture fits within established taxonomy of impulse electronics.

The remaining sections explain the boundary-level accounting framework (Section 03), the measurement protocol with critical port clarification (Section 04), the architecture under test (Section 05), the EMI/EMC architecture relevant for telecom deployment (Section 06), the numerical bridge from event-level dynamics to continuous power (Section 07), the endurance record itself (Section 08), the regime stability envelope (Section 09), and the scope boundaries of what this test confirms (Section 10).

03 · Two-Level Energy Model · Mandatory Distinction

Two Levels. Never Collapse Them.

The system must be interpreted at two strictly separated analytical levels. Major misinterpretations arise when these two levels are collapsed into a single model. Endurance test data must be read through both levels — never one alone.

Level 1

Device-Boundary Level — Classical Conservation Applies at All Operational States

All energy flows are referenced at the electrical terminals of the complete device boundary as accounting quantities
Classical energy conservation applies at all operational states

P_in,boundary = P_load + P_losses + dE/dt η = P_load / P_in,boundary ≤ 1

Level 2

Regime Level — Energy Is Structured and Redistributed

Within the formed regime, energy is structured, redistributed, and stabilised through:

Regime formation through controlled discharge cycle at 2.45 MHz
Regime stability via the regulated feedback path (Circuit B)
Controlled extraction through the load path (Circuit B)

Local ratios at this level describe redistribution between sub-blocks; they do not redefine the boundary balance.

Transformer Analogy · Seal Point

“A transformer’s secondary winding can deliver more current than its primary, while voltage drops in the same ratio. The local current ratio is greater than one; the device-boundary power balance remains governed by classical conservation. Local ratios describe redistribution between sub-blocks; the boundary describes conservation.”

Endurance-Specific Interpretation Note

Endurance test results must be read through both levels. Runtime persistence — 1,000+ hours cumulative regime runtime, 532 hours sustained at 4 kW — describes Level 2 (regime-level behavior), the persistence of the formed regime under sustained load. Delivered energy — ~4 MWh cumulative across the disclosed validation window, including 2.128 MWh delivered during the 532 h × 4 kW sustained segment — is accounted at Level 1 (device-boundary level). At Level 1, all delivered energy is referenced at the AC interface within the same boundary balance: P_in,boundary integrates over the operating interval to account for delivered output, irreversible losses, and stored energy change. Conflating runtime (Level 2 quantity) with delivered energy (Level 1 quantity) is a category error — they describe different layers of the same system.

04 · Black-Box Boundary Protocol · Measurement Framework

Two Boundary Interfaces. Two Distinct Functions.

The test was conducted under a black-box boundary measurement protocol — a methodology where system boundaries are defined exclusively by external electrical interfaces, with no internal circuit measurements included in the validation summary. The boundary has two interfaces, each with a distinct function. Their roles must be read separately.

Interface 1

Ignition Port — Startup Interface, Disconnected After Regime Initiation

The ignition port carries a low-energy startup impulse used to establish the initial conditions of the operating regime. The startup sequence is defined as: 9 V battery source, ~15 seconds duration, startup energy ≈ 0.015 Wh.

After successful regime ignition, the startup source is physically disconnected from the ignition path. The ignition port plays no further role during the sustained operation interval.

Interface 2

AC Interface — Operational Boundary, Continuously Active

The AC interface is the operational boundary of the device. It is the interface where external electrical input is referenced (P_in,boundary) and where load output is delivered through the inverter coupling (220 V / 50 Hz). External input flows in at the referenced electrical terminals; load output flows out through the inverter to the external load.

During sustained operation, the AC interface remains continuously active. P_in,boundary is referenced at the electrical terminals of this interface as an accounting quantity. Boundary-level accounting closes here.

Arithmetic Check · Closing Misinterpretation

A common misreading frames the test as “after ignition disconnect, no external input remains”. The arithmetic forecloses this reading: 532 hours × 4 kW = 2,128 kWh of delivered energy. The startup impulse was 0.015 Wh. 2,128 kWh and 0.015 Wh differ by a factor of approximately 1.4 × 10⁸.

Sustained delivered energy of this magnitude cannot derive from the startup impulse alone. The continued external electrical input during sustained operation flows through the AC interface, not through the ignition port.

Laboratory Configuration · Two Physically Separate Units

Test Unit & Setup Unit

The laboratory setup included two physically separate units: the Test Unit (the device under endurance evaluation, operated in sealed black-box configuration; all reported measurements correspond exclusively to this unit) and the Setup Unit (used exclusively for parameter adjustment and preliminary configuration; not part of the endurance record). No electrical power, control signal, or energy transfer was present between the units during the endurance interval. This separation is standard laboratory practice in nonlinear electrodynamic systems.

05 · Architecture Under Test · Two Functional Contours

Two-Contour Functional Architecture with Three Resonant Winding Circuits

The patent (ES2950176, WO2024209235) describes a discharge-resonant architecture grouped at the functional level into two contours, with three resonant winding circuits at the patent-component level. Two patent-disclosed claims define the operational anchors:

Claim 5: three parallel spark gaps with overlapping but shifted frequency spectra

Interaction Medium

Air/gas in the spark gaps functions as the interaction medium — not as an energy source. The field is the mediator that structures energy transfer within the formed regime. The field performs work on accelerated carriers; the working medium serves as the carrier reservoir.

Physics Mechanism · Townsend Avalanche

Inside the spark gaps, gas ionisation is governed by Townsend avalanche carrier multiplication: n(x) = n₀ · e^αx. The nonlinear discharge dynamics produce comparatively low per-cycle energy losses, which is one of the reasons the regime is sustainable under continuous load over extended duration.

06 · EMI/EMC Architecture · Telecom-Compatible Design

2.45 MHz Resonance — Without the Microwave Problem.

Standard engineering intuition expects an impulse architecture operating at 2.45 MHz primary resonance to produce significant electromagnetic radiation. Impulse circuits in the MHz-range RF band, near the MF/HF boundary, typically require careful field-management because materials couple to RF energy in this range. The first reasonable question from any engineer is therefore: does VENDOR.Max radiate?

Frequency Disambiguation · MHz Is Not GHz

The 2.45 MHz primary resonance is three orders of magnitude lower than the 2.45 GHz ISM band used by microwave ovens. These are different coupling regimes and must not be conflated:

2.45 MHz (MHz-range RF band, near the MF/HF boundary): used in industrial RF applications; coupling regime appropriate for this range differs from microwave coupling
2.45 GHz (microwave band): used by microwave ovens for water-molecule dielectric heating

The relevant engineering question for VENDOR.Max is therefore RF emission containment in the 2.45 MHz RF range, not microwave coupling. The architecture and the empirical evidence below address this specific RF-range question.

Standard Expectation

MHz-Range RF Impulse Systems — Field Management Required

Conventional architectures with impulse discharges in the 2.45 MHz RF range would produce significant electromagnetic radiation outside the device. For a power node intended for co-location with telecom equipment, this would be a deployment-blocking issue: telecom installations require electromagnetic compatibility under the CE EMC Directive 2014/30/EU and GSMA radiation-environment standards.

A device that radiates at MHz-range frequencies cannot be installed near antenna systems, base-station electronics, or sensitive measurement equipment without compliant emission containment.

VENDOR.Max Architecture

Why It Is Different — Field-Confinement Engineering

The engineering implementation of the primary winding (4) and the mechanical compounding of the resonant structure are designed to localize the electromagnetic field inside the resonant coupling between the three winding circuits — primary (4), secondary (7), and tertiary (10). The radiation pattern is contained within the device boundary by the engineering realization of the resonant topology, not by external shielding alone.

This is one of the engineering choices protected as know-how at TRL 5–6, alongside the specific construction of the discharger unit and the phase-alignment methodology between the three resonant circuits. Patent ES2950176 / WO2024209235 specifies the architectural topology; the engineering realization that achieves field confinement is consciously undisclosed in public materials at the current validation stage. This is standard deep-tech IP practice.

Empirical Evidence · Internal Spot Measurements

Spot measurements were performed in close proximity to the operating prototype during the endurance interval, using calibrated handheld instruments:

Instrument Reading Reference Range Status
SOEKS Quantum · dosimeter 0.13 µSv/h Natural background 0.10–0.30 µSv/h Within range
MEGEON EMF meter 0.34 µT Typical indoor ambient level Within range

VENDOR.Max safety monitoring — SOEKS Quantum dosimeter and MEGEON EMF meter spot measurements during prototype endurance test

Spot measurements performed in close proximity to the VENDOR.Max prototype during endurance operation. Instruments: SOEKS Quantum · MEGEON EMF meter.

Why This Matters · Telecom Co-LocationField-Confinement Architecture as Deployment Constraint

The target deployment context for VENDOR.Max includes remote telecom towers, base-station sites, and infrastructure-grade installations. EMI/EMC compatibility is a categorical requirement in these environments — not a refinement. The field-confinement architecture is therefore one of the central engineering constraints that defines deployment viability for the target audience. The empirical evidence to date — measurements within ambient range during operation — is consistent with a field-confined topology. Independent accredited measurement is the next milestone.

07 · Numerical Bridge · From Events to Power

Million-Event Integration. Standard Electrodynamics.

Endurance results — 4 kW continuous output over 532 hours — derive from the integration of millions of small discharge events per second through a standard event-level / power-level bridge. The arithmetic is simple and standard for pulse-power systems.

Event-Level Energy Distribution

Internal Redistribution Per Discharge Event

E_{extract,event} = E_load,event + E_fb,event + E_{loss,conv,event}

Notation footnote (canonical clarification): E_{extract,event} denotes energy coupled into the internal extraction path within the formed regime. It is a Level 2 regime-level allocation term, already evaluated under Level 1 boundary accounting. It does not imply energy extraction from air, gas, or the environment.

Per single discharge event, energy is internally distributed across three functional paths within the same device boundary: load delivery, feedback redistribution, and conversion losses. This is a Level 2 (regime level) accounting equation — it describes intra-cycle internal redistribution, not boundary-level input.

Bridge from Event Level to Continuous Power

Average Power as Event Energy Times Frequency

P_x,avg = E_x,event · f

At operating frequency f = 2.45 MHz and sustained load P_load = 4 kW, the corresponding event-level load energy is:

E_load,event = P_load / f = 4000 W / 2.45 × 10⁶ Hz ≈ 1.63 mJ per event

Verifiable Arithmetic

4000 / (2.45 × 10⁶) = 1.633 × 10⁻³ J = 1.633 mJ. This is the small event-level energy quantum that, when integrated over millions of discharge events per second, produces the 4 kW average power delivered at the AC interface.

Reference Framework

This relation appears in standard textbooks on pulsed power and plasma discharges (Raizer 1991, Lieberman & Lichtenberg 2005). It is not a novel claim — it is a standard discipline of distinguishing scales: microscopic event dynamics versus macroscopic boundary balance. Conflating the two scales without applying the bridge produces order-of-magnitude reading errors.

How This Explains the Endurance Data

1,000+ hours of cumulative regime runtime corresponds to integration of approximately f × t = 2.45 × 10⁶ × 3.6 × 10⁶ ≈ 8.8 × 10¹² discharge events per 1,000 hours of operation. Each event redistributes a small energy quantum (~1.6 mJ at 4 kW load); the macroscopic 4 kW continuous output is the integration of these events over time. The boundary-level accounting (Level 1) closes at the AC interface throughout.

They do not, by themselves, constitute full boundary-level energy balance verification. All measurements use calibrated instrumentation under black-box boundary measurement protocol.

09 · Regime Stability Envelope · Bounded Operation

Stability Within Bounded Envelope. Not Across Arbitrary Load.

The operating behavior of the VENDOR.Max system is defined by a load-dependent stability envelope characteristic of nonlinear electrodynamic regimes. Stability exists only within a bounded regime-compatible operating range. This bounded behavior is typical for nonlinear resonant systems and does not imply arbitrary scalability.

Condition 01

Upper Stability Threshold

If the regime is configured for ~4.8 kW (modular configuration based on 2.4 kW blocks), operation remains stable up to that threshold. Loading the system above this level (e.g., 5 kW) leads to immediate regime collapse in fixed-regime-mode configuration.

Condition 02

Lower Configuration Stability

If the regime is configured for a lower level (e.g., 2.4 kW), exceeding that level results either in regime collapse or in protective shutdown, depending on the specific configuration.

Condition 03

Sub-Threshold Operation

If the applied load remains below the configured regime level (e.g., 1 kW load with a 2.4 kW regime configuration), the system maintains the established regime for extended periods within that bounded operating condition. Internal feedback redistribution sustains regime coherence under fixed load conditions, limited by internal losses, component stability, and degradation over time.

Tested Operating Point · Within Stability Envelope

532-Hour Sustained Segment at 4 kW

The 532-hour sustained segment was conducted at 4 kW within a regime configuration with an upper stability threshold of approximately 4.8 kW. The applied load remained well within the predefined stability envelope for the entire duration. The endurance test was intentionally conducted below the upper stability threshold to ensure long-duration regime persistence under controlled operating conditions.

The specified upper threshold of 4.8 kW reflects a regime stability boundary under the given configuration. It is not a certified output rating, maximum capacity, or continuous operating specification. Certified ratings are defined at the CE/UL certification stage at TRL 8.

Fixed-Regime Mode vs. Buffered Mode

Scope of This Endurance Record

The endurance record on this page describes fixed-regime-mode operation (no BMS storage layer) under fixed load. In buffered-mode configuration, the internal BMS and storage layer enable dynamic load adaptation and transient-peak compensation within defined protection limits. Buffered-mode operation represents a different deployment configuration; its characterization is not included in this endurance record.

Direct Answers · Structured Clarity

Five Direct Answers to Five Direct Questions.

Direct, scope-bounded answers to the five most common engineering questions about the endurance test — written for fast technical reading and consistent interpretation.

What does the endurance test prove?

Verdict · Regime persistence under load

The endurance test confirms that the VENDOR.Max prototype maintains a stable nonlinear electrodynamic operating regime under continuous electrical load for over 1,000 hours of cumulative runtime, including a 532-hour sustained segment at 4 kW. ~4 MWh of cumulative delivered energy was observed under validation-stage measurement at the AC interface, within calibration tolerance. Pre-commercial validation stage at TRL 5–6.

Was external power connected during the 532-hour sustained segment?

Verdict · AC interface remained continuously active

The startup impulse at the ignition port (0.015 Wh) was disconnected after regime initiation. The AC interface — the operational boundary where external electrical input is referenced and load output is delivered through the inverter coupling — remained continuously active throughout the sustained segment. P_in,boundary at the AC interface is referenced as the accounting quantity at the complete device boundary.

How can 532 h × 4 kW = 2,128 kWh derive from 0.015 Wh of startup?

Verdict · It cannot

The arithmetic difference between 2,128 kWh of delivered energy and 0.015 Wh of startup impulse is approximately 1.4 × 10⁸. Sustained delivered energy of this magnitude does not derive from startup alone. The continued external electrical input flows through the AC interface during sustained operation. P_in,boundary at the AC interface accounts for delivered output, losses, and stored-energy change throughout.

Why is event-level energy (~1.6 mJ) compatible with continuous 4 kW?

Verdict · Event integration at 2.45 MHz

At operating frequency f = 2.45 MHz and sustained load P_load = 4 kW, the event-level load energy is E_load,event = P_load / f ≈ 1.63 mJ per event. The macroscopic 4 kW continuous output is the integration of millions of these events per second. This is a standard scale-distinguishing relation in pulse-power literature (Raizer 1991, Lieberman & Lichtenberg 2005). Conflating event energy with continuous power produces order-of-magnitude reading errors.

Does the system radiate at 2.45 MHz?

Verdict · Field-confinement architecture

Standard expectation for impulse architectures at 2.45 MHz would be significant electromagnetic radiation. The engineering implementation of the primary winding (4) and the resonant topology localizes the field inside the resonant coupling between the three winding circuits. Empirical evidence: SOEKS Quantum reads 0.13 µSv/h (natural background range), MEGEON EMF meter reads 0.34 µT (typical indoor ambient level) in close proximity to the operating prototype. The field-confinement implementation is protected as know-how at TRL 5–6. Full EMI/EMC accredited measurement is part of the CE certification milestone at TRL 8.

FAQ · Technical Clarity

Frequently Asked, Precisely Answered.

Seven canonical questions on the endurance test record — answered through the boundary-accounting framework, scope-bounded to the disclosed validation window.

01 What does the 1,000+ hour endurance test prove?

The test confirms that the VENDOR.Max prototype maintains a stable nonlinear electrodynamic operating regime under continuous electrical load for over 1,000 hours of cumulative runtime. Within this period, continuous operation at 4 kW was sustained for 532 hours, with ~4 MWh of cumulative delivered energy across the disclosed validation window. This is a TRL 5–6 internal validation result. Independent verification at the AC interface under accredited metrological protocol is the next pre-commercial validation milestone.

02 How does the boundary protocol define the measurement interfaces?

The black-box boundary measurement protocol defines two distinct interfaces: (1) the ignition port — used only for startup impulse (0.015 Wh, ~15 seconds), then physically disconnected; and (2) the AC interface — operational boundary where external electrical input is referenced (P_in,boundary) and load output is delivered through the inverter coupling at 220 V / 50 Hz, continuously active during sustained operation. P_in,boundary is referenced at the AC interface as an accounting quantity throughout the validation window.

03 How can sustained 4 kW operation be consistent with event-level energies of ~1.6 mJ?

At operating frequency f = 2.45 MHz, the event-level load energy is E_load,event = P_load / f = 4000 W / (2.45 × 10⁶ Hz) ≈ 1.63 mJ per event. The macroscopic 4 kW continuous output is the integration of approximately 2.45 million discharge events per second. This relation (P = E·f) is standard for pulse-power systems. Without applying this bridge, comparing milli-joules per event with kilowatts of continuous output produces order-of-magnitude reading errors.

04 Why is the boundary defined at the AC interface — what about internal processes?

Boundary-level accounting (Level 1) is evaluated at the complete device boundary, where all energy inputs and outputs are referenced as accounting quantities: P_in,boundary = P_load + P_losses + dE/dt. Internal processes — regulated feedback path, BMS coordination, discharge dynamics — operate at regime level (Level 2). Local ratios at regime level describe redistribution between sub-blocks; they do not redefine the boundary balance. Drawing the measurement boundary around a subsystem (such as Circuit A only) instead of the complete device produces a boundary-definition artifact, not a physics phenomenon.

05 Does the system radiate at 2.45 MHz given the impulse discharge regime?

The 2.45 MHz primary resonance would, in conventional impulse architectures, produce significant electromagnetic radiation. The engineering implementation of the primary winding (4) and the resonant topology localizes the field inside the resonant coupling between the three winding circuits. Internal spot measurements during the endurance interval — SOEKS Quantum at 0.13 µSv/h (natural background range) and MEGEON EMF meter at 0.34 µT (typical indoor ambient level) — are consistent with field-confined operation. Full EMI/EMC compliance measurement under accredited laboratory protocol is part of the CE certification milestone at TRL 8.

06 Can the system operate at any load, or is stability load-dependent?

Stability is load-dependent. The system maintains operation only within a bounded regime-compatible operating range — the regime stability envelope. The 532-hour sustained segment was conducted at 4 kW within a regime configuration with an upper stability threshold of approximately 4.8 kW. Loading above the configured threshold leads to regime collapse in fixed-regime-mode configuration. This bounded behavior is typical for nonlinear resonant systems and does not imply arbitrary scalability — bounded stability within a defined envelope, not unrestricted operation across arbitrary load levels.

07 What does this test record represent — and what does it not?

This page documents regime persistence under sustained load conditions, measured under a black-box boundary protocol with calibrated instrumentation, at pre-commercial validation stage TRL 5–6. It does not establish certified energy efficiency, accredited safety compliance, EMI/EMC certification, or commercial readiness. Internal mechanism interpretation remains subordinate to boundary-level measurement. Independent verification under accredited laboratory protocols and CE/UL certification at TRL 8 are the next milestones in the pre-commercial validation pathway.

Interpretation Discipline

This page should be read within the framework of pulse-power engineering, nonlinear electrodynamics, and validation-stage deep-tech IP practice. It documents validation-stage measurement at TRL 5–6, not certified performance. The Two-Level Energy Model (Level 1 device-boundary, Level 2 regime) must not be collapsed into a single layer. The black-box boundary protocol uses the AC interface as the operational boundary throughout sustained operation; the ignition port is a startup-only interface.

Final Interpretation Note

All operational parameters represent validation-stage measurement at TRL 5–6. A discrete startup impulse initiates the electrodynamic regime; the regime is then maintained by the regulated feedback path under BMS control with continued external electrical input flowing through the AC interface. At the complete device boundary, P_in,boundary = P_load + P_losses + dE/dt applies at all operational states. The boundary-level energy balance under sustained load is subject to independent verification at the next pre-commercial validation milestone. Internal mechanism interpretation remains subordinate to boundary-level measurement.
