Governed Space

Representation Limitation

Canonical Definition

Representation Limitation Module (RLM) defines the governance conditions under
which known, discovered, unavoidable, accepted, conditional, and unresolved
limitations in a simulation's representation of reality are identified,
classified, assessed, bounded, documented, propagated, monitored, and
preserved throughout the simulation lifecycle.

RLM establishes the final governance layer of Reality Representation by
determining where the internal simulated representation stops being
sufficiently representative of the reality it claims to model, what
consequences follow from that limitation, and which simulation conclusions,
scenarios, conditions, or uses must therefore remain restricted.

RLM does not require a simulation to represent reality perfectly.

It requires the difference between:

Represented Reality

and:

Relevant Reality

to remain governable.

Operational Role

The preceding Reality Representation modules establish:

RSM — What parts of reality must be represented?

RAM — How may selected reality legitimately be simplified?

RFM — How faithfully must the representation correspond to material reality?

RRM — At what resolution must material phenomena remain distinguishable?

RLM asks:

What material limitations remain after reality selection, abstraction,
fidelity, and resolution have been established, and how must those limitations
constrain subsequent simulation use and interpretation?

The governed progression is:

Selected Reality → Approved Abstraction → Required Fidelity → Required
Resolution → Limitation Identification → Limitation Classification →
Materiality Assessment → Limitation Boundary → Propagation → Representation
Limitation Status

RLM closes the Reality Representation Standard before the simulation proceeds
into subsequent SIMULOS® governance spaces.

Module Operational Space

RLM governs: representation limitation identification, known limitations,
discovered limitations, inherent limitations, technical limitations,
methodological limitations, abstraction limitations, fidelity limitations,
resolution limitations, data-dependent representation limitations,
environmental representation limitations, behavioral representation
limitations, interaction limitations, temporal limitations, spatial
limitations, boundary limitations, omitted-reality limitations, simplification
effects, representational uncertainty, limitation materiality, limitation
severity, limitation applicability, limitation dependencies, limitation
interaction, limitation accumulation, limitation acceptance, conditional
limitation acceptance, unresolved limitations, limitation propagation,
limitation disclosure, limitation monitoring, limitation change, limitation
reassessment, limitation status, and limitation traceability.

Module Function

Every simulation represents reality imperfectly.

This is not automatically a defect.

A simulation necessarily selects, simplifies, discretizes, approximates,
aggregates, excludes, and transforms aspects of reality.

The governance problem begins when those differences are: unknown,
undocumented, misunderstood, materially underestimated, disconnected from
simulation outputs, hidden during interpretation, or ignored when simulation
results are used.

RLM exists to prevent: simplifications becoming invisible, known
representation weaknesses disappearing from later simulation stages, omitted
reality being mistaken for irrelevant reality, high fidelity in one area
masking serious limitations elsewhere, limitations being described generically
without identifying affected outcomes, accepted limitations being interpreted
as resolved limitations, computational constraints silently redefining
represented reality, representation limitations being lost when simulations
are reused, and simulation outputs being interpreted beyond what the
represented reality can legitimately support.

Representation Limitation Principle

SIMULOS® establishes:

A limitation does not invalidate a simulation merely because it exists. A
limitation becomes methodologically dangerous when its existence, materiality,
boundary, or consequence is not governed.

The objective is therefore not:

No Limitations

but:

Known + Assessed + Bounded + Propagated Limitations Representation Limitation

A Representation Limitation is a known or reasonably identifiable condition
under which the internal simulation representation does not fully preserve a
materially relevant property, behavior, relationship, state, event, variation,
or boundary of Relevant Reality.

A limitation may arise from: deliberate simplification, unavailable knowledge,
unavailable data, computational constraints, measurement constraints, modeling
choices, environmental complexity, unknown behavior, resolution limits,
abstraction, incomplete representation, or inherent inability to reproduce the
relevant phenomenon.

Limitation Object

A Limitation Object is the specific representation element affected by a
limitation.

It may include: a represented entity, environment, behavior, interaction,
dependency, process, state, event, population, physical phenomenon, temporal
condition, spatial condition, or representation boundary.

Each material limitation should be linked to the object it affects.

Limitation Origin

The origin of a limitation should remain identifiable where possible.

Possible origins include:

Reality Selection

Reality Abstraction

Representation Fidelity

Representation Resolution

Source Data

Modeling Constraint

Computational Constraint

Measurement Constraint

Environmental Uncertainty

Knowledge Gap

or:

Unknown Origin

This distinction matters because different limitation origins may require
different downstream treatment.

Known Limitation

A Known Limitation is identified before or during simulation design.

Known limitations should not disappear merely because they were accepted
during design.

Acceptance does not eliminate their relevance.

Discovered Limitation

A Discovered Limitation emerges after the representation has been established.

It may arise during: scenario design, simulation execution, output
examination, reality correlation, external review, incident analysis, or later
operational use.

A discovered material limitation should be propagated backward and forward
through affected simulation governance spaces.

Inherent Limitation

An Inherent Limitation exists where the phenomenon cannot reasonably be
represented with sufficient completeness under the available simulation
approach.

Examples may include: highly uncertain human behavior, unknown future
environmental conditions, unresolved physical processes, incomplete causal
knowledge, or phenomena whose relevant characteristics cannot yet be measured.

An inherent limitation may still permit simulation.

Its consequences must remain bounded.

Technical Limitation

A Technical Limitation arises from the capabilities of the simulation
implementation or infrastructure.

Examples may include: computational capacity, memory limits, solver
constraints, platform limitations, maximum agent population, sensor emulation
limits, or execution-time constraints.

Technical limitations must not silently redefine the methodological
requirements of the simulation.

Methodological Limitation

A Methodological Limitation arises from the representational approach itself.

It may result from: modeling assumptions, selected abstractions, mathematical
formulation, approximation method, behavioral model, aggregation strategy, or
representational structure.

Abstraction Limitation

An Abstraction Limitation exists where an approved simplification removes
distinctions that remain relevant under particular conditions.

An abstraction may therefore be legitimate generally but limited for a
particular scenario.

Fidelity Limitation

A Fidelity Limitation exists where representation correspondence to reality is
weaker than required for a particular phenomenon, state, interaction, or
interpretation.

RFM identifies fidelity conditions.

RLM governs the resulting limitation where the gap remains.

Resolution Limitation

A Resolution Limitation exists where the representation cannot distinguish
material phenomena at the required granularity.

RRM identifies and assesses resolution sufficiency.

RLM carries unresolved resolution consequences into the complete
Representation Limitation profile.

Omitted-Reality Limitation

Reality excluded from representation may later prove materially relevant.

An Omitted-Reality Limitation exists where an excluded element can materially
affect the simulation inquiry.

This does not automatically mean that the original exclusion was unjustified.

It means the exclusion now constrains interpretation.

Boundary Limitation

A simulation boundary may prevent representation of external effects.

A Boundary Limitation may arise where: external systems influence the
simulated system, environmental conditions cross the boundary, human actions
occur outside the modeled environment, dependencies extend beyond the
simulation, or feedback enters from excluded reality.

Behavioral Limitation

Behavioral models may represent only a bounded set of behaviors.

Where real actors or systems may behave outside that set, the difference
should remain visible.

Interaction Limitation

An Interaction Limitation exists where relevant interactions are: simplified,
aggregated, delayed, omitted, approximated, or represented conditionally.

Interaction limitations can be material even when individual simulation
objects are accurately represented.

Environmental Limitation

An Environmental Limitation exists where environmental complexity exceeds the
represented environment.

Examples may include incomplete representation of: weather, terrain,
infrastructure, traffic, electromagnetic conditions, resource availability,
human activity, or operational disturbances.

Temporal Limitation

A Temporal Limitation exists where the representation cannot sufficiently
preserve relevant time-dependent behavior.

This may concern: duration, sequence, timing, latency, degradation,
seasonality, transition speed, or long-term evolution.

Spatial Limitation

A Spatial Limitation exists where the representation does not sufficiently
preserve materially relevant spatial differences.

Data-Dependent Representation Limitation

A representation may be structurally capable of representing a phenomenon
while available data prevents that capability from being meaningfully
populated.

RLM distinguishes:

Representation Capability

from:

Representation Support

A sophisticated representation built upon weak or incomplete data may remain
materially limited.

Representational Uncertainty

A limitation and uncertainty are related but not identical.

Limitation asks:

What can the representation not sufficiently preserve?

Uncertainty asks:

How uncertain are we about the represented condition or its correspondence to
reality?

A limitation may exist with low uncertainty.

For example, a known excluded subsystem.

Uncertainty may exist without a known structural limitation.

RLM preserves the distinction.

Limitation Identification

Limitation identification should ask:

Where does the simulation representation materially differ from Relevant
Reality in a way that could affect the simulation inquiry?

Identification should consider: excluded reality, abstractions, fidelity gaps,
resolution gaps, model boundaries, environmental simplifications, interaction
simplifications, behavioral constraints, data constraints, and known unknowns.

Limitation Materiality

Not every representation difference is material.

A limitation becomes material where it can reasonably affect: simulation
behavior, scenario behavior, output interpretation, reality correlation,
uncertainty, downstream evidence, intended reliance, or conclusions derived
from the simulation.

Materiality Is Purpose-Relative

A limitation may be immaterial for one simulation purpose and critical for
another.

For example:

A simplified wind model may be acceptable for:

Long-Term Energy Production Estimation

but materially insufficient for:

Emergency Turbine Load Simulation.

Therefore:

Representation Limitation Materiality = Limitation × Simulation Purpose ×
Scope × Scenario × Intended Interpretation

conceptually, not numerically.

Limitation Severity

Material limitations may be classified according to their effect.

A practical classification may include:

Minor

The limitation does not materially change the principal simulation
interpretation.

Moderate

The limitation affects defined outputs, scenarios, or conditions.

Major

The limitation materially restricts important simulation conclusions.

Critical

The limitation prevents legitimate use of the representation for a material
simulation purpose.

Undetermined

The consequence cannot yet be sufficiently established.

Limitation Applicability

A limitation should identify where it applies.

Applicability may be bounded by: scenario, object, subsystem, environment,
population, operational mode, time period, geographic area, failure condition,
output, or simulation claim.

Global vs Local Limitation

A limitation may be:

Local

affecting only a defined part of the simulation,

or:

Global

affecting the complete representation or principal simulation inquiry.

Local limitations should not automatically invalidate unaffected
representation.

Global limitations should not be hidden by unaffected local strengths.

Conditional Limitation

A limitation may activate only under defined conditions.

For example:

Representation sufficient below wind speed
X

but:

Representation limited above wind speed X.

Conditional limitations should remain linked to the conditions that activate
them.

Limitation Interaction

Multiple individually acceptable limitations may interact.

For example:

Moderate Fidelity Limitation Moderate Resolution Limitation Limited
Environmental Representation

may together create a major limitation for one simulation conclusion.

RLM therefore evaluates limitations both individually and collectively.

Limitation Accumulation

A simulation should not assume that individually accepted limitations remain
acceptable when accumulated.

RLM asks:

Does the combined limitation profile materially weaken the representation
beyond the intended simulation boundary?

Weakest Material Representation Principle

SIMULOS® establishes:

A simulation conclusion cannot legitimately assume stronger representation
than the materially limiting representation condition upon which that
conclusion depends.

Strong representation elsewhere does not erase a critical limitation.

Limitation Dependency

A limitation may affect other representation elements.

For example:

Environmental Limitation

may affect:

Sensor Representation → Behavioral Response → Interaction → Simulation Output

RLM therefore preserves limitation dependencies where material.

Limitation Propagation

Material representation limitations must propagate to downstream simulation
governance.

Conceptually:

Representation Limitation

↓

Assumption Governance

↓

Model & Environment

↓

Inputs & Data

↓

Scenario Design

↓

Simulation Execution

↓

Simulation Output

↓

Reality Correlation

↓

Simulation Evidence

↓

Reliance Boundary

The limitation need not affect every downstream stage.

But affected stages must not remain unaware of it.

No Limitation Laundering Rule

SIMULOS® establishes:

A known material representation limitation may not disappear merely because
the simulation proceeds to a later lifecycle stage.

Changing terminology does not resolve the limitation.

Producing outputs does not resolve the limitation.

Successful execution does not resolve the limitation.

Limitation Acceptance

A material limitation may sometimes be accepted.

Acceptance requires a governed basis.

The acceptance should establish: the limitation, affected representation,
materiality, consequence, applicable scope, conditions, residual uncertainty,
and resulting interpretation boundary.

Accepted ≠ Resolved

SIMULOS® establishes:

Accepted Limitation ≠ Resolved Limitation

Acceptance means the simulation may proceed while the limitation remains
explicitly bounded.

Conditional Acceptance

A limitation may be accepted only under defined conditions.

For example:

Accepted for normal operation scenarios

but:

Not accepted for emergency failure scenarios.

Unresolved Limitation

An Unresolved Limitation exists where: materiality cannot be established,
consequences remain uncertain, mitigation is incomplete, available evidence is
insufficient, or the limitation remains incompatible with the intended
simulation inquiry.

Unresolved limitations must remain visible.

Limitation Mitigation

Where appropriate, limitations may be reduced through: expanded reality
representation, changed abstraction, improved fidelity, increased resolution,
better data, improved model structure, broader environment representation,
additional scenarios, or narrower simulation claims.

RLM governs the limitation status.

It does not prescribe one universal mitigation technique.

Residual Limitation

After mitigation, a limitation may remain.

The remaining condition becomes the Residual Representation Limitation.

Residual limitations must be assessed independently of the original
limitation.

Limitation Closure

A limitation may be closed only where it is:

Resolved

or:

No Longer Applicable

Closure should not be used merely because the limitation was accepted.

Representation Limitation Status

RLM may establish:

Representation Limitations Acceptable

Representation Limitations Conditionally
Acceptable

Representation Partially Limited

Representation Materially Limited

Representation Critically Limited

or:

Representation Limitation Status
Undetermined

The status must remain bounded to the Simulation Purpose, Scope, scenarios,
and intended interpretation.

Representation Limitation Profile

The Representation Limitation Profile consolidates material limitations
affecting the simulated representation.

It should preserve:

Limitation → Origin → Affected Object → Materiality → Severity → Applicability
→ Dependencies → Acceptance Status → Residual Limitation → Downstream
Consequence

This profile becomes a primary governance output of RLM.

Limitation Disclosure

Material limitations should be disclosed wherever simulation results could
otherwise be interpreted more broadly than the representation supports.

Disclosure should be: specific, understandable, linked to affected results,
and proportionate to materiality.

Generic statements such as:

“The simulation has limitations.”

are insufficient where specific material limitations are known.

Limitation-to-Output Binding

Where a limitation affects only particular outputs, the limitation should
remain bound to those outputs.

This prevents one global disclaimer from obscuring which conclusions remain
strong and which are constrained.

Limitation-to-Scenario Binding

Where a limitation applies only to certain scenarios, it should remain linked
to those scenarios.

Limitation-to-Condition Binding

Conditional limitations should remain linked to their activation conditions.

Limitation Change

Representation limitations may change as the simulation evolves.

A limitation may:

Appear

Increase

Decrease

Change Scope

Become Conditional

Become Material

Become Non-Material

Be Resolved

or:

Become Unknown

Material change should trigger reassessment.

Limitation Reassessment

Reassessment may be required when: Simulation Purpose changes, Scope changes,
Relevant Reality changes, abstraction changes, fidelity changes, resolution
changes, model structure changes, new data becomes available, new scenarios
are introduced, new outputs are used, reality correlation reveals mismatch, or
intended reliance expands.

Representation Change Rule

SIMULOS® establishes:

A limitation assessment is valid only for the representation configuration,
purpose, scope, conditions, and interpretation against which it was
established.

Material changes may invalidate the previous assessment.

Limitation Versioning

Material limitation profiles should remain version-linked to the relevant
simulation representation.

A limitation profile for:

Representation Version 1.2

should not automatically be assumed applicable to:

Representation Version 2.0.

Historical Limitation Preservation

Resolved limitations may remain historically relevant.

They may explain: prior outputs, earlier discrepancies, previous simulation
decisions, historical reliance, or later model changes.

RLM therefore preserves material limitation history.

Limitation Traceability

A governed limitation chain should support:

Relevant Reality → Representation Decision → Limitation Origin → Limitation
Object → Materiality → Severity → Applicability → Acceptance / Resolution →
Residual Limitation → Downstream Effect

This allows an independent reviewer to reconstruct:

what was not represented sufficiently, why, and what consequences followed.

Representation Limitation Boundary

RLM governs limitations of simulation reality representation.

It does not own every limitation affecting a simulation.

Examples:

Representation Limitation

→ RLM

Assumption Limitation

→ subsequent SIMULOS® assumption governance

Input Data Limitation

→ SIMULOS® Inputs & Data governance

Execution Limitation

→ Simulation Execution governance

Validation Limitation

→ VALIDOS®

General Integrity Failure

→ INTEGROS®

This separation prevents RLM from becoming a generic limitation standard for
the entire architecture.

Relationship to Reality Selection

RSM determines what reality belongs inside the representation.

RLM governs material consequences where selected or excluded reality creates a
representational limitation.

Relationship to Reality Abstraction

RAM governs whether simplification is legitimate.

RLM governs material limitations that remain because of that simplification.

Relationship to Representation Fidelity

RFM governs required correspondence with reality.

RLM governs unresolved consequences where fidelity remains bounded.

Relationship to Representation Resolution

RRM governs required granularity.

RLM governs unresolved consequences where resolution remains limited.

Relationship to ORA™

ORA™ governs actual Operational Reality.

RLM does not redefine operational reality.

It governs where the simulation's representation of that reality remains
limited.

Relationship to VALIDOS®

RLM does not determine whether a simulation or simulation-derived claim is
formally valid.

VALIDOS® governs validation.

RLM provides a governed representation-limitation basis that may become
relevant evidence or a validation constraint.

Relationship to INTEGROS®

RLM does not govern general integrity.

INTEGROS® may govern integrity of representation objects, records, limitation
records, and related lifecycle artifacts.

Relationship to ADIT®

Where continuous auditability or evidential reconstruction is required, ADIT®
may preserve observation and evidence concerning representation decisions and
limitation changes.

Use Case 1 — Autonomous Driving Simulation

Scenario

An autonomous-driving simulation represents urban traffic with high vehicle
and sensor fidelity but models pedestrian behavior using a limited set of
deterministic movement patterns. Application

RLM identifies a:

Behavioral Representation Limitation

The limitation is assessed as relatively minor for:

Basic Lane-Keeping Simulation

but major for:

Pedestrian Collision-Risk Simulation.
Result

The simulation may continue to support the first inquiry.

Its use for the second must remain restricted until pedestrian behavioral
representation is improved or the limitation is otherwise appropriately
bounded. Use Case 2 — Spacecraft Thermal Simulation

Scenario

A spacecraft thermal simulation accurately represents the spacecraft but uses
simplified environmental assumptions for an unusual orbital condition.
Application

RLM identifies an:

Environmental Representation Limitation

applicable specifically to the unusual orbital scenario. Result

Normal-orbit simulation outputs remain unaffected.

Outputs for the unusual orbital condition receive an explicit limitation
boundary and cannot inherit the representational confidence of normal-orbit
scenarios. Use Case 3 — Financial System Stress Simulation

Scenario

A systemic financial simulation models institutional relationships but omits
several indirect dependency channels because reliable data is unavailable.
Application

RLM identifies:

Omitted-Reality + Data-Dependent +
Interaction Limitations

Each limitation alone may appear moderate.

Their interaction is assessed as potentially major under extreme stress
scenarios. Result

The limitation profile restricts interpretation of systemic contagion outputs
and propagates the limitation into affected scenario and output governance.

Architectural Position

Representation Limitation is the fifth and final internal governance space of
the Reality Representation Standard (RRS).

The complete RRS progression is:

Reality Selection → Reality Abstraction → Representation Fidelity →
Representation Resolution → Representation Limitation

Together, the five modules answer:

What reality must be represented?

↓

How may it be simplified?

↓

How faithfully must it correspond to reality?

↓

At what granularity must material phenomena remain distinguishable?

↓

What material representational limitations remain and how must they constrain
the simulation?

RLM therefore closes the Reality Representation governance space by producing
a bounded and traceable representation basis for the next SIMULOS® Parent
Standard.

Foundational Principle

A simulation does not become trustworthy by eliminating every representational
limitation; it becomes governable when every material limitation remains
identifiable, bounded, traceable, and inseparable from the conclusions it can
affect.

Canonical Closing Statement

Representation Limitation Module completes the Reality Representation Standard
by governing the material differences that remain between Relevant Reality and
its simulation representation after reality selection, abstraction, fidelity,
and resolution have been established. Through limitation identification,
origin attribution, materiality assessment, severity classification,
applicability boundaries, interaction analysis, acceptance governance,
residual-limitation assessment, downstream propagation, disclosure,
reassessment, versioning, and traceability, RLM prevents known
representational weaknesses from disappearing as simulations progress toward
scenarios, execution, outputs, evidence, validation, and operational reliance.
RLM therefore establishes the governed boundary between what the simulation
representation can legitimately support and what remains outside its
representational capability.
