TREGA™

Tax-Relevant Event Governance Architecture —
Tax-Relevant Event Governance Layer

TREGA™ serves as the official OOF® tax-relevant event governance
architecture used for Event Context governance, Event
Recognition, Event Formation, Event Boundary governance, Event
Timing, Event Location, Event Participation, Value Association,
Event Relationship governance, Event Determination, Event Record
Governance, and Event Lifecycle & Continuity governance across
physical transactions, digital services, financial systems,
commerce platforms, AI agents, autonomous systems,
machine-to-machine environments, distributed systems,
cross-border activity, organizations, and future taxation
environments.

TREGA™ does not determine taxation itself. TREGA™ defines the
governance architecture required to ensure that real-world,
economic, operational, digital, transactional, machine-generated,
autonomous, and value-affecting occurrences become explicitly
contextualized, recognized, formed, bounded, temporally and
spatially situated, associated with participants and value,
related to other Events, formally determined as tax-relevant,
represented as governed records, and maintained throughout their
lifecycle before jurisdiction-specific taxation rules are
applied.

TREGA™ consists of 12 Core Parent Standards and 60 Core Modules
forming the primary Tax-Relevant Event Governance backbone within
the OOF® ecosystem.

Additional compatible standards, bridge standards, and
specialized Event Governance standards may extend the
architecture when new Tax-Relevant Event Governance spaces are
identified. However, the standards listed below form the official
core Tax-Relevant Event Governance structure of TREGA™.

Canonical Definition

TREGA™ — Tax-Relevant Event Governance Architecture™ is the
jurisdiction-neutral governance architecture that establishes how
real-world, economic, operational, digital, transactional,
machine-generated, autonomous, and value-affecting occurrences
are contextualized, recognized, formed into governed Events,
bounded, temporally and spatially situated, associated with
participants and value, related to other Events, formally
determined as tax-relevant, recorded, and maintained throughout
their lifecycle before jurisdiction-specific taxation rules are
applied.

Reporting / Compliance Core Parent Standards 1. Tax-Relevant
Event Context Standard (TRECS)

Governed Space: Tax-Relevant Event Context

Core Question: Within what governed operational, economic,
digital, transactional, organizational, or machine context does
the occurrence exist, and which contextual boundaries and
relationships are relevant to its Event governance?

2. Tax-Relevant Event Recognition Standard
(TRERS)

Governed Space: Tax-Relevant Event
Recognition

Core Question: Which occurrence should enter Tax-Relevant Event
Governance, under what recognition conditions, and with what
confidence, qualification, or escalation state?

3. Tax-Relevant Event Formation Standard
(TREFS)

Governed Space: Tax-Relevant Event
Formation

Core Question: How must a recognized occurrence be assembled into
a governed Event, which components constitute it, and what
operational root relationship supports its formation?

4. Tax-Relevant Event Boundary Standard
(TREBS)

Governed Space: Tax-Relevant Event
Boundary

Core Question: Where does the governed Event begin and end, what
belongs inside or outside it, and how must it remain
distinguishable from adjacent or related Events?

5. Tax-Relevant Event Timing Standard
(TRETS)

Governed Space: Tax-Relevant Event Timing

Core Question: When does the Event begin, continue, complete, and
relate temporally to other Events without converting operational
Event Timing into a jurisdiction-specific legal tax point or Tax
Period?

6. Tax-Relevant Event Location Standard
(TRELS)

Governed Space: Tax-Relevant Event
Location

Core Question: Where does the Event occur physically, digitally,
operationally, or across distributed environments without
converting Event Location into Tax Jurisdiction determination?

7. Tax-Relevant Event Participation
Standard (TREPS)

Governed Space: Tax-Relevant Event
Participation

Core Question: Which human, organizational, digital, machine, or
autonomous actors materially participate in the Event, in what
roles, and with what continuity without determining taxpayer
status?

8. Tax-Relevant Value Association Standard
(TRVAS)

Governed Space: Tax-Relevant Value
Association

Core Question: Which governed Value states, changes, transfers,
or relationships belong to the Event, and how must they remain
associated without duplicating Value lifecycle governance itself?

9. Tax-Relevant Event Relationship
Standard (TRERLS)

Governed Space: Tax-Relevant Event
Relationships

Core Question: How is the Event related to other Events through
dependency, sequence, grouping, Merge, Split, or other materially
relevant relationships?

10. Tax-Relevant Event Determination
Standard (TREDS)

Governed Space: Tax-Relevant Event
Determination

Core Question: When is an Event sufficiently governed to be
formally determined as tax-relevant and eligible for downstream
taxation analysis without determining whether the Event is
legally taxable?

11. Tax-Relevant Event Record Governance
Standard (TREGS)

Governed Space: Tax-Relevant Event Record
Governance

Core Question: How can a Determined Tax-Relevant Event be
represented as a stable, identifiable, structured, linked,
traceable, and interoperable governed record without allowing the
record to redefine the Event or determine its legal tax
consequence?

12. Tax-Relevant Event Lifecycle &
Continuity Standard (TRECLS)

Governed Space: Tax-Relevant Event
Lifecycle & Continuity

Core Question: How can a governed Tax-Relevant Event remain
continuous, reconstructable, correctable, and jurisdiction-ready
throughout change without erasing historical reality or
converting Event lifecycle governance into tax-law
administration?

Compatible OOF® Architectures

TREGA™ interoperates with multiple OOF® architectures governing
complementary governance spaces.

GOA™ — Governance Architecture provides the constitutional
governance layer defining how governance itself is structured,
bounded, delegated, and maintained.

ORA™ — Operational Reality Architecture governs what is actually
occurring in Operational Reality, while TREGA™ governs how
occurrences are transformed into governed Tax-Relevant Events for
downstream taxation analysis.

OBIDENITY® — Origin-Bound Identity Governance Architecture®
governs identity, origin, ownership, authority, permission,
provenance, transfer, and continuity, while TREGA™ governs which
identified actors materially participate in the Event.

VFM® — Value Flow Mechanism governs what happens to Value
throughout its lifecycle, while TREGA™ governs which governed
Value result belongs to a specific Tax-Relevant Event.

CLA® — Classification Architecture governs classification of
objects and states, while TREGA™ governs Event-specific
tax-relevance determination and lifecycle.

VALIDOS™ — Validation Governance Architecture governs whether a
validation basis sufficiently supports a Validation
Determination, while TREGA™ governs whether an Event is
sufficiently structured and governed to enter downstream taxation
analysis.

INTEGROS® — Integrity Governance Architecture governs integrity
across objects, states, evidence, and processes, while TREGA™
governs Event-specific structure, determination, representation,
and lifecycle.

ADIT® governs evidential observation, preservation, verification,
examination, and auditability of what occurred, while TREGA™
governs the Event itself and the governed structures through
which it becomes tax-relevant.

AGA™ — Accountability Governance Architecture governs authority,
responsibility, accountability, attribution, and decision
relationships surrounding Event governance and downstream
reliance.

HALIA™ — Harm & Liability Architecture governs the lifecycle of
harm and liability where Event consequences create relevant harm
or liability relationships.

TREGA™ serves as the common Tax-Relevant Event Governance
architecture supporting the broader OOF® ecosystem by ensuring
that operational occurrences become governed Events before
jurisdiction-specific taxation systems determine their legal tax
meaning.

Architectural Position

TREGA™ governs the complete Tax-Relevant Event lifecycle before
jurisdiction-specific tax determination begins.

The architecture progresses through:

Real-World / Digital Event

↓

Event Context

↓

Event Recognition

↓

Event Formation & Root Association

↓

Event Boundary

↓

Event
Timing

↓

Event Location

↓

Event Participation

↓

Value Association

↓

Event Relationships

Event Determination

↓

Governed Tax-Relevant Event Record

↓

Event Continuity

& Lifecycle

↓

Jurisdiction-Ready Tax-Relevant Event

Together these standards govern how an occurrence is placed
within context, recognized as requiring Event Governance, formed
into a governed Event, bounded, situated in time and location,
associated with participants and Value, connected to other
Events, formally determined as tax-relevant, transformed into a
governed Event Record, and maintained throughout its lifecycle
until it becomes jurisdiction-ready.

TREGA™ then hands the governed Event to downstream taxation
infrastructure:

Jurisdiction-Ready Tax-Relevant Event

↓

Jurisdictional Tax Rules
/ Tax Engine

↓

Tax Determination

↓

Reporting / Compliance

Unlike a tax determination methodology, TREGA™ remains
jurisdiction-neutral throughout the complete Event Governance
lifecycle.

The multi-jurisdiction model becomes:

One Event

↓

One Governed Event Layer

↓

Multiple Jurisdictional Evaluations

This enables one governed Event Reality to be consumed by
multiple jurisdiction-specific taxation systems without requiring
TREGA™ to redefine the Event separately for each jurisdiction.

Core Governed Tax-Relevant Event Spaces

TREGA™ establishes twelve distinct governable Tax-Relevant Event
spaces:

Tax-Relevant Event Context

→ within what operational, economic, digital, organizational, or
machine environment the Event exists.

Tax-Relevant Event Recognition

→ which occurrence should enter Tax-Relevant Event Governance.

Tax-Relevant Event Formation

→ how the recognized occurrence becomes a governed Event and how
its root association is established.

Tax-Relevant Event Boundary

→ what belongs inside and outside the Event.

Tax-Relevant Event Timing

→ when the Event begins, continues, completes, and relates
temporally to other Events.

Tax-Relevant Event Location

→ where the Event occurs physically, digitally, operationally, or
across distributed environments.

Tax-Relevant Event Participation

→ which actors materially participate in the Event and in what
roles.

Tax-Relevant Value Association

→ which governed Value results belong to the Event.

Tax-Relevant Event Relationships

→ how the Event depends upon, sequences with, groups with, merges
with, or splits from other Events.

Tax-Relevant Event Determination

→ whether the Event is sufficiently governed to become a
Determined Tax-Relevant Event.

Tax-Relevant Event Record Governance

→ how the Determined Event becomes identifiable, structured,
linked, traceable, and interoperable as a Governed Tax-Relevant
Event Record.

Tax-Relevant Event Lifecycle & Continuity

→ how the governed Event remains continuous, amendable,
correctable, supersedable, closable, and jurisdiction-ready
throughout its lifecycle.

Each space answers a different methodological question.

Each can fail independently.

Their separation is therefore foundational to the TREGA™
architecture.

Cross-Architecture Boundary Lock

TREGA™ is intentionally bounded to prevent duplication with
adjacent OOF® architectures and jurisdiction-specific tax
systems. TREGA™ ↔ ORA™

ORA™: What actually happened in Operational Reality?

TREGA™: How does that occurrence become a governed Tax-Relevant
Event?

Operational Reality ≠ Tax-Relevant Event Governance. TREGA™ ↔
OBIDENITY®

OBIDENITY®: Who or what is the actor, under what origin,
ownership, authority, permission, and provenance?

TREGA™: Does that actor materially participate in this governed
Event, and in what Event role?

Identity ≠ Event Participation.

Identified Actor ≠ Governed Event Participant. TREGA™ ↔ VFM®

VFM®: What happened to Value throughout its lifecycle?

TREGA™: Which governed Value result belongs to this Event?

Value Governance ≠ Event Value Association. TREGA™ ↔ VALIDOS™

TREGA™: Has the Event been sufficiently governed to support
downstream taxation analysis?

VALIDOS™: Does the total validation basis sufficiently support a
Validation Determination and intended reliance?

Event Determination ≠ Validation Determination. TREGA™ ↔
INTEGROS®

TREGA™: governs Event-specific context, recognition, formation,
boundary, timing, location, participation, value association,
relationships, determination, record, and lifecycle.

INTEGROS®: governs integrity across objects, states, evidence,
and processes.

Tax-Relevant Event Governance ≠ General Integrity Governance.
TREGA™ ↔ ADIT®

TREGA™: governs the Event and its canonical governance lifecycle.

ADIT®: governs evidential observation, preservation,
verification, examination, and auditability of what occurred.

Event Governance ≠ Audit of Event Governance. TREGA™ ↔ AGA™

TREGA™: governs the methodological Event lifecycle.

AGA™: governs who holds authority, responsibility,
accountability, and attribution for Event-related decisions,
actions, and failures.

Event Methodology ≠ Accountability Allocation. TREGA™ ↔ HALIA™

TREGA™: governs the Tax-Relevant Event lifecycle.

HALIA™: governs the lifecycle of harm and liability arising from
relevant occurrences.

Tax-Relevant Event Governance ≠ Harm or Liability Determination.

TREGA™ ↔ Jurisdictional Tax Systems

TREGA™: determines whether an occurrence has become a
sufficiently governed Tax-Relevant Event suitable for downstream
analysis.

Jurisdictional Tax System: determines what that Event legally
means under applicable tax law.

Tax-Relevant Event ≠ Legally Taxable Event.

Jurisdiction-Ready ≠ Jurisdiction-Determined.

Architectural Origin

TREGA™ evolved from the foundational methodological problem that
taxation systems require a reliable Event layer between
operational reality and legal tax determination.

Traditional taxation infrastructure often moves directly from:

Transaction Data

↓

Tax Rules

without explicitly governing what the underlying Event actually
is.

As digital platforms, distributed systems, autonomous agents,
machine-to-machine activity, cross-border services, and future
machine economies expand, the Event itself becomes increasingly
difficult to identify, bound, locate, associate with participants
and Value, relate to other Events, and preserve through time.

TREGA™ therefore establishes a dedicated governance architecture
between:

Operational Reality

and:

Jurisdiction-Specific Tax Determination

Its foundational principles are distributed primarily across:

Event Context

↓

Event Recognition

↓

Event Formation

↓

Event
Boundary

↓

Event Timing

↓

Event Location

↓

Event Participation

↓

Value Association

↓

Event Relationships

↓

Event Determination

↓

Event Record Governance

↓

Event

Lifecycle & Continuity

The architecture establishes the governed Tax-Relevant Event as
an independent methodological object before downstream tax law
determines legal consequence.

Architectural Structure

  • Architecture: TREGA™ — Tax-Relevant Event Governance
    Architecture™
  • Category: Governance & Enforcement
  • Subcategory: Tax-Relevant Event Governance
  • Core Parent Standards: 12
  • Core Modules: 60
  • Architecture Model: Lifecycle-Based · Modular ·
    Jurisdiction-Neutral


Primary Governance Domain: Tax-Relevant
Event Governance

The architecture deliberately separates governable spaces that
can independently fail.

A taxation-relevant occurrence may:

- be placed in the wrong Context; - fail to be recognized; - be
incorrectly formed; - contain an incorrect Event Boundary; - have
inaccurate Timing; - have incomplete or misleading Location
information; - associate the wrong participants; - associate the
wrong Value result; - be incorrectly related to other Events; -
be prematurely determined as tax-relevant; - become an incomplete
or semantically unstable Event Record; - lose lifecycle
continuity through uncontrolled Amendment, Correction,
Supersession, or Closure.

TREGA™ treats these not as one generic tax data problem, but as
distinct Event Governance spaces requiring distinct
methodological controls.

Recursive Lifecycle Principle

TREGA™ does not end when a Tax-Relevant Event Record is first
created.

A governed Event may continue to change after its initial
Determination and Record Governance.

During that period:

New information may emerge.

Event attributes may require Amendment.

Previously governed information may require Correction.

A successor state may Supersede a prior state.

Continuity may become uncertain.

An Event may close.

A Closed Event may require reopening.

Material transformation may require New Event Formation.

TREGA™ therefore closes recursively through TRECLS:

Governed Tax-Relevant Event Record

↓

Event Continuity

↓

Event
Amendment

↓

Event Correction

↓

Event Supersession

↓

Event Closure

↓

Jurisdiction-Ready

Tax-Relevant Event

Where materially relevant new information emerges:

Closed Event

↓

Reopening Review

↓

Lifecycle Re-Entry

↓

Updated
Governed Event

↓

Reclosure

Where continuity can no longer legitimately be preserved:

Material Transformation

↓

Continuity Break

↓

New Event Formation Referral

This makes Event change part of Tax-Relevant Event Governance
rather than an uncontrolled downstream data-maintenance problem.

Foundational Architecture Principles

TREGA™ governs the event. The jurisdiction governs the tax.

Tax-Relevant Event ≠ Legally Taxable Event.

Tax relevance means eligibility for taxation analysis, not legal
taxability.

Operational Reality must not become tax interpretation before the
Event itself has been governed.

Recognition ≠ Taxability Determination.

Formation ≠ Boundary.

Event Root ≠ Identity Origin.

Operational Event Time ≠ Legal Tax Point.

Event Timing ≠ Tax Period Determination.

Event Location ≠ Tax Jurisdiction.

Participant ≠ Taxpayer.

Identified Actor ≠ Governed Event Participant.

Value Association ≠ Value Governance.

Event Determination ≠ Tax Liability Determination.

Governed Event Record ≠ Tax Assessment.

Correction ≠ Historical Erasure.

Amendment ≠ New Event by default.

Material Transformation May Require New Event Formation.

Event Continuity ≠ Tax Obligation Lifecycle.

Jurisdiction-Ready ≠ Jurisdiction-Determined.

One governed Event can support multiple legitimate jurisdictional
evaluations without becoming multiple different Event realities.

Canonical Principle

TREGA™ does not govern legal Taxability, Tax Jurisdiction,
taxpayer determination, tax nexus, legal tax point, Tax Period,
Tax Base, Tax Rate, exemptions, deductions, Tax Liability, filing
obligations, payment, collection, enforcement, or other
jurisdiction-specific legal tax consequences. TREGA™ governs the
methodological conditions under which real-world and digital
occurrences become contextualized, recognized, formed, bounded,
temporally and spatially situated, associated with participants
and Value, related to other Events, formally determined as
tax-relevant, represented as governed Event Records, and
maintained through Amendment, Correction, Supersession, Closure,
and continuity governance until they become Jurisdiction-Ready
for downstream tax-rule application.

TREGA™ governs the event. The jurisdiction governs the tax.
