applicable, repeatability conditions, reproducibility conditions, execution

Governed Simulation Execution Record.


Operational Scope

SES applies to simulation execution across environments including: AI systems,
autonomous systems, robotics, multi-agent systems, aerospace and space
systems, industrial systems, digital twins, infrastructure systems,
transportation systems, scientific and engineering simulations, financial and
economic simulations, safety simulations, mission simulations, training
simulations, synthetic environments, hardware-in-the-loop environments,
software-in-the-loop environments, and future simulation systems.


SES is technology-neutral.

It does not prescribe a particular: simulator, simulation engine, programming
language, computational infrastructure, numerical method, orchestration
platform, or execution technology.


Execution Object

Every governed simulation execution should be distinguishable as an
identifiable execution object.


Depending upon implementation, this may be:

Simulation Run

Simulation Episode

Simulation Trial

Simulation Batch

Simulation Campaign

or another defined execution unit.

The governing requirement is not terminology.

The governing requirement is:

the executed activity must be sufficiently identifiable to reconstruct what
actually occurred.


Simulation Execution ID

A materially relevant simulation execution should have a stable identifier
capable of connecting the execution to its governing basis.


Conceptually:

Simulation Execution ID

↓

Simulation Object Version

Purpose & Scope

Reality Representation

Assumption Basis

Model Version

Environment Version

Input Set

Scenario ID

Parameter Configuration

Execution Conditions

Execution Record

Produced Outputs

This prevents simulation results from becoming detached from the execution
that produced them.


Instantiation Principle

A simulation specification does not become an executed simulation merely
because its components exist.


SES distinguishes:

Defined Simulation Configuration

from:

Instantiated Simulation Configuration.

Instantiation establishes which exact versions, parameters, inputs, scenarios,
environments, and relevant conditions were assembled for a specific execution.


Configuration Binding

Before execution, materially relevant components should be bound to the
execution instance.


This may include: Simulation Object version, model version, environment
version, scenario version, input dataset, parameter set, software
configuration, hardware configuration, random seed, dependency state, external
service configuration, and execution timestamp.


No Assumed Configuration Principle

SIMULOS® establishes:

The configuration intended to run must not automatically be treated as the
configuration that actually ran.


Where material, execution records should establish the instantiated
configuration rather than relying solely upon pre-execution intent.


Execution Authorization

Where organizational, technical, safety, financial, or regulatory consequence
requires authorization, SES may require an identifiable authorization basis
before execution.


Authorization may govern: permitted scenario classes, resource limits,
execution environment, access permissions, external-system interaction,
sensitive data, hardware use, operational interfaces, and termination
authority.


Execution Initiation

Execution Initiation marks the transition from prepared simulation
configuration to active simulation.


A governed initiation record may establish: execution identity, initiation
time, configuration status, scenario, inputs, environment, authorization, and
initial state.


Execution State

SES may distinguish execution states such as:

Prepared

Initialized

Running

Paused

Interrupted

Restarted

Completed

Terminated

Failed

or:

Execution State Unknown.

These states allow downstream users to distinguish a successfully completed
simulation from a partial or interrupted execution.


Execution Control

Simulation Execution Control governs the mechanisms through which execution
remains within the conditions established for the simulation.


Controls may concern: execution sequence, timing, resource use,
synchronization, scenario progression, parameter application, dependency
behavior, state transitions, interventions, runtime limits, termination
criteria, and recovery behavior.


Execution Control ≠ Outcome Control

A critical SIMULOS® distinction is:

Execution Control governs how the simulation is performed. It must not become
manipulation designed to force a preferred simulation outcome.


Unexpected or unfavorable behavior should remain observable rather than being
silently corrected merely because it conflicts with expectations.


Runtime Intervention

A simulation may require intervention during execution.

Examples include: pause, parameter adjustment, injected failure, scenario
escalation, external input, human intervention, recovery command, or
controlled termination.


Where intervention can materially affect the result, it should remain
traceable.


No Invisible Intervention Principle

SIMULOS® establishes:

A material intervention during simulation execution must not disappear from
the execution history.


Execution Deviation

An Execution Deviation exists where actual execution materially differs from
the intended execution basis.


Examples include: wrong configuration, missing dependency, delayed input,
unexpected environment state, parameter mismatch, runtime error, unscheduled
intervention, timing failure, resource exhaustion, incomplete scenario
execution, or execution-system failure.


Deviation Does Not Automatically
Invalidate Execution

SES does not predetermine the consequence of a deviation.

Instead it requires the deviation to remain visible.

A deviation may be:

Immaterial

Material but Acceptable

Conditionally Acceptable

Execution-Limiting

Execution-Invalidating

or:

Undetermined

depending upon downstream assessment.

Execution Observation

Simulation Observation governs the structured capture of materially relevant
events and states during execution.


Observation may concern: system state, environment state, agent behavior,
transitions, failures, recoveries, interactions, timing, resource consumption,
control events, interventions, anomalies, and emergent behavior.


Observation ≠ Interpretation

SES establishes a strong boundary:

Observation records what occurred during execution. Interpretation determines
what that occurrence means.


The latter belongs primarily to downstream output and analytical governance.

Observation Context

An observation without sufficient context may become misleading.

Where material, observations should preserve:

What happened

When it happened

Where in the simulation it happened

Under which configuration

Under which scenario

Under which inputs

Under which execution state

and:

What preceded or followed the event.

Observation Resolution

Not every simulation requires identical observation resolution.

Observation may be: continuous, periodic, event-triggered,
threshold-triggered, state-triggered, sampled, or selectively captured.


The appropriate resolution depends upon the Simulation Purpose and materially
relevant execution phenomena.


Observation Blind Spots

SES should preserve known observation limitations.

Examples include: unlogged internal states, insufficient sampling frequency,
unavailable telemetry, inaccessible agent reasoning, missing environment
events, or data lost during execution.


A simulation should not later be represented as fully observed where material
execution regions were not observable.


Execution Repetition

A simulation may be repeated to examine: consistency, variability, stochastic
behavior, uncertainty, scenario sensitivity, parameter sensitivity, rare
events, or distributional behavior.


SES governs how repetitions remain distinguishable and comparable.
Repeatability


Repeatability concerns whether materially equivalent execution conditions can
produce sufficiently comparable execution behavior when repetition is intended
to preserve those conditions. Reproducibility


Where applicable, Reproducibility concerns whether another execution
environment, actor, system, or implementation can recreate the materially
relevant simulation execution basis sufficiently to examine comparable
behavior.


SIMULOS® does not assume every simulation must be perfectly reproducible.

Some simulations contain: stochastic processes, nondeterministic hardware,
external services, adaptive agents, distributed systems, real-time human
interaction, or changing environments.


The requirement is to govern the conditions affecting reproducibility rather
than falsely claim determinism.


Randomness Governance

Where randomness materially affects execution, SES may govern: randomization
method, seed identity, seed generation, seed reuse, stochastic
parameterization, sampling state, and relationship between randomization and
repetitions.


Seed Traceability

Where technically applicable and materially relevant, preserving a random seed
may allow an execution to be reconstructed.


However:

Seed preservation alone does not establish
reproducibility

if other execution conditions have changed.

Repetition Identity

Every repeated execution should remain distinguishable.

For example:

Scenario S-104

may produce:

Run S-104-R001

Run S-104-R002

Run S-104-R003

and so forth.

The exact naming system is implementation-specific.

Controlled Repetition

SES distinguishes:

Controlled Repetition

from:

Uncontrolled Re-Running.

Controlled repetition preserves sufficient information to determine: what
remained constant, what changed, why it changed, and whether resulting
executions may legitimately be compared.


Repetition Variance

Repeated simulations may intentionally vary: seed, input, parameter,
environment, agent population, timing, scenario condition, or another
dimension.


Such variation should remain distinguishable from accidental execution drift.

Execution Drift

Execution Drift occurs where repeated simulations cease to represent
materially comparable execution conditions without that change being
sufficiently governed.


Possible causes include: software updates, infrastructure changes, model
changes, environment updates, dependency changes, altered defaults, parameter
changes, or orchestration changes.


Execution Comparability

Two simulation executions should not be treated as directly comparable merely
because they share the same Scenario ID.


Comparability may also depend upon: model version, environment version, input
basis, parameterization, randomization, execution controls, and material
runtime conditions.


Simulation Campaign Governance

Large simulation programs may execute:
thousands, millions, or billions

of simulation runs.

SES allows these runs to be governed as a Simulation Campaign while preserving
sufficient run-level traceability where material.


Campaign Identity

A Simulation Campaign may bind:

Campaign ID

↓

Simulation Purpose

↓

Scenario Set

↓

Execution Configuration

↓

Run Population

↓

Repetition Logic

↓

Execution Controls

↓

Campaign Record Campaign-Level Control

Campaign-level governance may establish: permitted configurations, scenario
population, execution infrastructure, resource limits, repetition rules,
stopping conditions, logging requirements, exception handling, and
documentation requirements.


Run-Level Exceptions

A campaign may be generally conformant while individual runs contain
deviations.


SES should therefore preserve the distinction between:

Campaign Status

and:

Individual Execution Status.

Execution Completeness

Execution Completeness asks:

Was the simulation activity required by the instantiated execution basis
actually completed sufficiently?


Possible states may include:

Complete

Conditionally Complete

Partially Complete

Incomplete

Failed

or:

Undetermined. Completion ≠ Successful
Outcome

A simulation may execute completely and reveal catastrophic system failure.

That may still represent a fully completed simulation execution.

Likewise, a simulation producing an apparently desirable output may have been
incompletely executed.


SIMULOS® therefore establishes:

Execution Completeness and Simulation Outcome are separate governable
questions.


Execution Documentation

Simulation Execution Documentation preserves the execution history
sufficiently for later reconstruction.


Documentation may include: Execution ID, Campaign ID, object version, model
version, environment version, scenario, inputs, parameters, assumptions where
material, authorization, start time, completion time, execution state,
interventions, deviations, observations, repetition relationship,
randomization basis, infrastructure state, completion status, and output
references.


Execution Provenance

Execution Provenance establishes where a Simulation Execution Record came from
and which technical and governance basis produced it.


Execution Lineage

Execution Lineage connects related runs.

For example:

Baseline Run

↓

Repeated Run

↓

Modified Parameter Run

↓

Stress Escalation Run

↓

Recovery Run

This allows simulation evolution to be reconstructed rather than viewed as
disconnected output files.


Point-in-Time Reconstruction

SES should enable questions such as:

Which exact model version ran?

Which scenario version was instantiated?

Which inputs were used?

Which parameters were active?

Which environment version existed?

Was the execution interrupted?

Was there a runtime intervention?

Was the run repeated?

Which seed was used where applicable?

Were material anomalies observed?

Was the execution complete?

Which outputs originated from this execution?

No Orphan Output Principle

SIMULOS® establishes:

A material Simulation Output should remain traceable to the Simulation
Execution that produced it.


An output detached from its execution basis loses critical interpretive
context.


No Successful-Run Selection Bias

Where a Simulation Campaign produces both expected and unexpected executions,
SES should preserve material failed, interrupted, anomalous, and unfavorable
runs.


SIMULOS® establishes:

Simulation Execution governance must not preserve only the runs that support
the preferred conclusion.


Failed Executions as Information

Failed executions may reveal: infrastructure weaknesses, scenario
incompatibility, model instability, resource constraints, timing problems, or
previously unknown simulation limitations.


SES therefore treats execution failure as governable information rather than
disposable noise.


Autonomous Simulation Execution

AI and autonomous systems may increasingly: generate simulations, select
scenarios, instantiate environments, modify parameters, execute campaigns,
identify anomalies, and launch follow-up simulations automatically.


SES remains applicable.

The execution record should preserve where material:

Human-Initiated Execution

AI-Initiated Execution

Autonomously Triggered Execution

or another relevant execution authority state.

Adaptive Simulation

An adaptive simulation may alter future execution based upon earlier results.

For example:

Run

↓

Observation

↓

Adaptive Scenario Selection

↓

New Run

↓

New Observation

SES should preserve this causal execution chain.

No Hidden Adaptive Path Principle

Where prior simulation results materially determine subsequent execution
selection, the adaptive path should remain reconstructable.


Otherwise the resulting campaign may appear predetermined when it was actually
dynamically generated.


Human-in-the-Loop Simulation

Where humans participate during simulation, SES may preserve: participant
role, intervention authority, intervention timing, decisions, response delay,
override, and materially relevant human actions.


Hardware-in-the-Loop Simulation

For hardware-in-the-loop environments, execution records may additionally
preserve: hardware identity, hardware configuration, firmware version,
calibration state, communication state, timing characteristics, and physical
interface conditions.


Software-in-the-Loop Simulation

Software-in-the-loop execution may preserve: software build, dependencies,
runtime environment, API versions, model versions, configuration, and
orchestration state.


Space and Mission Simulation

Space and aerospace simulation programs may execute enormous campaigns across:
trajectories, navigation uncertainty, environmental conditions, communication
states, propulsion states, sensor states, subsystem failures, autonomy states,
and recovery conditions.


SES governs not merely whether these simulations were launched but whether the
execution history can establish:


which mission configuration actually ran under which conditions and what
occurred during that run.


This becomes especially important when simulation campaigns are used to
support decisions that cannot later be easily tested in operational reality.


Autonomous Systems

For autonomous systems, execution governance becomes particularly important
where behavior can depend upon: internal state, prior actions, memory,
stochasticity, environment changes, external agents, timing, permissions, and
adaptive decision paths.


Two runs using nominally identical scenarios may diverge materially.

SES preserves the conditions necessary to understand that divergence.

Execution Bottleneck

In mature simulation programs, the bottleneck may not be computational
capacity.


Organizations may already possess enormous simulation infrastructure.

The bottleneck may instead be:

execution traceability across millions of runs.

Typical questions become:

Which configuration produced this result?

Can we reproduce it?

Was this run interrupted?

Was there an intervention?

Which environment version was active?

Which outputs belong to which execution?

Did failed runs disappear from analysis?

Did execution conditions drift across the campaign?

SES turns these questions into an explicit governance space.

Relationship to Simulation Scenario
Standard

SSS determines:

what should be simulated and whether materially relevant Scenario Space is
sufficiently covered.


SES determines:

how those scenarios are actually instantiated and executed.

Therefore:

Scenario Coverage ≠ Execution Completion.

A scenario may exist in the governed Scenario Set without ever being
successfully executed.


Relationship to Simulation Model &
Environment Standard

SMES governs construction, configuration, boundaries, parameterization, and
versioning of the simulation model and environment.


SES binds a specific governed model and environment configuration to an actual
execution.


Relationship to Simulation Input & Data
Standard

SIDS governs which data and inputs may enter the simulation and under which
conditions.


SES records which governed inputs actually entered a specific execution.

Relationship to Simulation Assumption
Standard

SAS governs the role of assumptions inside the simulation.

SES preserves the applicable assumption basis where it materially affects
execution reconstruction.


Relationship to Simulation Output
Governance Standard

SES ends by producing the governed execution basis from which simulation
outputs emerge.


SOGS begins by asking:

What exactly did the simulation produce, how should those outputs be
classified and bounded, and what may legitimately be inferred from them?


The handoff is therefore:

Governed Simulation Execution Record

↓

Simulation Output

↓

Simulation Output Governance Relationship
to VALIDOS®

VALIDOS® may later determine whether simulation execution records and outputs
are sufficient for a particular Validation Purpose.


SES does not make that Validation Determination.

This preserves the boundary:

Simulation Execution Governance ≠ Validation Governance.

Relationship to INTEGROS®

INTEGROS® may govern integrity properties of execution records, artifacts, or
related information.


SES does not duplicate general integrity governance.

SES governs the simulation-specific execution lifecycle.

Relationship to ADIT®

ADIT® may audit evidence and records produced by simulation execution.

SIMULOS® owns:

simulation execution itself.

ADIT® may subsequently ask whether the execution record is sufficiently
auditable, evidenced, or reconstructable for an audit purpose.


Relationship to ORA™

ORA™ governs actual Operational Reality.

SES governs activity occurring inside the simulation environment.

An execution that perfectly conforms to its simulation environment does not
establish that the environment accurately represents operational reality.


Relationship to ASGA™

ASGA™ may define governance requirements concerning autonomous authority,
permissions, override, escalation, coordination, and continuity.


SES may instantiate and observe scenarios exercising those conditions without
taking ownership of autonomous-system governance itself.


Execution Governance Boundary

SES begins when the upstream simulation basis is sufficiently established for
a scenario or simulation campaign to be instantiated.


SES ends when the required simulation activity has been: instantiated,
executed, controlled, observed, repeated where required, documented, linked to
material deviations, assigned an execution-completeness status, and preserved
as a Governed Simulation Execution Record capable of supporting downstream
Simulation Output Governance.


SES does not determine: whether the simulation model is universally valid,
whether Reality Representation is sufficient, whether the resulting output is
correct, whether an inference from the output is legitimate, whether
operational deployment should occur, whether a Validation Object is valid, or
whether a system is safe.

Governs repeated execution, randomization, repeatability, reproducibility
conditions, comparison, execution variance, and controlled repetition.


Its primary question is:

When a simulation is repeated, what must remain constant, what may change, and
how can repeated executions remain meaningfully comparable? 5. SEDM —
Simulation Execution Documentation Module


Governs the documentation, provenance, lineage, completeness, traceability,
and reconstructability of simulation execution.


Its primary question is:

Can the executed simulation later be reconstructed sufficiently to determine

Enterprise Application

SES can be applied over an organization's existing simulation infrastructure
without replacing the underlying simulator.


The organization may retain its: simulation engine, digital twin, HPC
infrastructure, Monte Carlo platform, robotics simulator, mission simulator,
AI evaluation environment, or proprietary simulation stack.


SES adds the governance layer that asks:

What actually ran?

Under which configuration?

Who or what initiated it?

What changed during execution?

What was observed?

Was it completed?

Was it repeated under comparable conditions?

Can the execution be reconstructed?

Can every material output be traced back to the execution that produced it?

This makes SES applicable as a simulation-execution governance and diagnostic
framework without requiring organizations to abandon existing technical
infrastructure.
