Executive Summary

The Coste360 Validation Evidence Catalogue (EA-009) establishes the official enterprise repository of validation evidence supporting the QEN Sovereign Intelligence Validation Programme.

The catalogue defines a centralized governance model for all evidence referenced by Enterprise Assessments.

EA-009 serves as the authoritative repository for evidence identification, classification, governance, traceability, auditability, lifecycle management, and reuse.

The catalogue does not perform assessments.

It does not express opinions.

It does not certify external platforms.

Its purpose is to provide a structured inventory of publicly observable evidence supporting independent enterprise validation activities.

EA-009 is designated as the Single Source of Truth for all validation evidence within the Coste360 Validation Programme.


Objectives

The objectives of this catalogue are to:

  • establish a centralized evidence repository;
  • define unique Evidence IDs;
  • standardize evidence classification;
  • support audit readiness;
  • enable evidence reuse;
  • eliminate duplication;
  • improve repository consistency;
  • support enterprise governance;
  • strengthen decision traceability;
  • provide lifecycle management for evidence.

Scope

This catalogue applies to all Enterprise Assessments produced within the Coste360 Validation Programme.

Enterprise Assessments shall reference Evidence IDs defined in this catalogue without duplicating the underlying evidence.

EA-009 governs the identification, maintenance, review, traceability and lifecycle of enterprise validation evidence.


Guiding Principles

The catalogue is based on the following principles:

  • Evidence First
  • Transparency
  • Explainability
  • Traceability

Purpose

The Evidence Taxonomy defines the official enterprise classification model applied to every Evidence ID managed by EA-009.

Each evidence item shall belong to one Primary Category and may optionally belong to multiple Secondary Categories.

This taxonomy enables consistent classification, traceability, reporting and cross-reference across the entire Validation Programme.

Primary Categories

The following categories constitute the official enterprise taxonomy.

CategoryDescription
PlatformPlatform capabilities and observable functionalities.
GovernanceGovernance structures, policies and decision processes.
DataData assets, models, metadata and information management.
SecuritySecurity controls, authentication and protection mechanisms.
ComplianceRegulatory, legal and policy compliance evidence.
OperationsOperational processes and runtime activities.
ArchitectureSystem architecture, components and design principles.
DocumentationOfficial documentation and technical publications.
TransparencyPublic transparency and explainability information.
Public CommunicationPublic announcements and institutional communications.
OrganizationOrganizational information and governance structures.
EcosystemExternal ecosystem integrations and collaborations.
IntegrationAPIs, interoperability and integration capabilities.
MonitoringMonitoring, observability and operational measurements.
QualityQuality assurance and validation evidence.

Evidence Classification Rules

Each Evidence ID shall include:

  • Evidence ID
  • Evidence Title
  • Primary Category
  • Secondary Categories
  • Evidence Owner
  • Source Type
  • Criticality Level

  • Current Version

No evidence shall remain unclassified.


Evidence Criticality Model

Every Evidence ID shall be assigned one criticality level.

LevelObjective Criteria
CriticalRequired to validate core enterprise capabilities or governance claims.
HighStrongly supports assessment conclusions and audit activities.
MediumImportant supporting evidence for validation.
LowInformational evidence with limited assessment impact.

Criticality shall be determined using objective validation criteria only.

Evidence PendingNot Yet Verified

Only publicly observable evidence shall be included unless explicitly governed otherwise.


Evidence Freshness Model

Each evidence item shall maintain one freshness status.

StatusDescription
CurrentRecently reviewed and considered valid.
Recently VerifiedIndependently verified during the latest assessment cycle.
Scheduled for ReviewReview already planned according to governance procedures.
ExpiredRequires revalidation before further use.
Evidence PendingValidation has not yet been completed.

Freshness shall be periodically reviewed according to repository governance procedures.


Review Policy

Evidence shall be reviewed periodically to ensure:

  • continued availability;
  • source integrity;
  • traceability;
  • technical consistency;
  • governance compliance;
  • assessment reliability.

Expired evidence shall not be referenced by new Enterprise Assessments until revalidated.



Evidence Risk Assessment

Each Evidence ID shall include a standardized enterprise risk assessment.

The assessment shall evaluate:

  • Risk if Missing
  • Risk if Outdated
  • Risk if Incorrect
  • Business Impact
  • Assessment Impact
  • Audit Impact
  • Repository Impact

Risk Classification

LevelDescription
CriticalPrevents reliable enterprise validation.
HighSignificantly affects assessment quality.
MediumReduces validation confidence but remains manageable.
LowLimited operational impact.

Risk evaluations shall be objective, documented and periodically reviewed.


Evidence Reuse Policy

The Coste360 Validation Programme adopts the principle:

Collect Once — Reuse Everywhere

Evidence shall be collected a single time and subsequently reused across the entire enterprise repository.

Benefits include:

  • elimination of duplication;
  • repository consistency;
  • improved maintainability;
  • simplified audits;
  • increased traceability;
  • reduced documentation effort.

A single validated Evidence ID may be referenced by an unlimited number of Enterprise Assessments.

No assessment shall duplicate evidence already governed by EA-009.


Evidence Change Control

Every Evidence ID shall follow a controlled lifecycle.

Lifecycle stages include:

  • Creation
  • Review
  • Approval
  • Modification
  • Deprecation
  • Replacement
  • Retirement

Every modification shall preserve historical traceability.

Deprecated evidence shall remain archived for audit purposes.

Evidence identifiers shall never be reassigned.


Evidence Audit Trail

Each modification shall generate a permanent audit record containing:

  • Evidence ID
  • Version
  • Date
  • Reviewer
  • Reason for Change
  • Approval Status

Additional optional attributes may include:

  • Previous Version
  • Repository Commit Reference
  • Related Enterprise Assessment
  • Validation Notes
  • Review Cycle

The audit trail shall remain immutable once approved.


Evidence Repository Integration Model

EA-009 represents the centralized enterprise evidence repository.

Enterprise Assessments shall reference Evidence IDs exclusively.

Evidence shall never be duplicated within assessment documents.

Each assessment shall maintain references only.

All evidence maintenance activities shall be performed within EA-009.

Repository synchronization shall therefore occur automatically through Evidence IDs.


Evidence Maturity Model

Evidence governance maturity shall be evaluated using the following model.

LevelDescription
Level 1Identified
Level 2Collected
Level 3Verified
Level 4Cross-Referenced
Level 5Fully Governed

Level 5 represents complete governance integration including traceability, lifecycle management, audit readiness and repository consistency.


Enterprise Repository Rules

EA-009 constitutes the official Single Source of Truth for validation evidence.

The following mandatory rules apply.

  1. Evidence shall never be duplicated.
  1. Enterprise Assessments shall reference Evidence IDs only.
  1. Evidence modifications shall be performed exclusively within EA-009.
  1. Repository traceability shall always be preserved.
  1. Evidence identifiers are permanent.
  1. Repository governance supersedes individual assessment copies.
  1. Cross-reference consistency shall be maintained across all Enterprise Assessments.

Alignment with QEN Sovereign Principles

EA-009 is formally aligned with the following approved governance artefacts:

  • ADR-CLE-004 — QEN Sovereign Intelligence Principle
  • AF-009 — QEN Semantic Identity & Trust Layer
  • AF-010 — QEN CLI
  • QEN Sovereign Governance Model
  • QEN Sovereign Documentation Reference Architecture
  • QEN Sovereign Documentation Index
  • Repository Sovereign Certification

These artefacts collectively establish the enterprise governance framework supporting evidence management, traceability and explainability.


Repository Governance Statement

EA-009 serves as the authoritative enterprise repository governing all validation evidence used throughout the Coste360 Validation Programme.

All Enterprise Assessments shall rely upon this catalogue for evidence identification, governance, lifecycle management and traceability.

EA-009 therefore functions as the central evidence repository for the entire validation framework.
