Canonical Definition

Evidence Preservation Module (EPRM) defines the structural conditions
under which evidence associated with the provenance of a governed
identity remains authentic, preserved, accessible, verifiable, and
continuously governable throughout the complete identity lifecycle.

EPRM governs evidence preservation.

The module establishes the governance conditions required to ensure
that every governance-relevant record supporting the provenance of a
governed identity remains protected against loss, alteration,
unauthorized removal, or corruption.

History creates evidence.

Governance preserves that evidence.

EPRM governs its preservation.

Module Operational Role

EPRM defines the evidence preservation layer of PRIS.

Its role is to preserve the documentary foundation supporting the
complete provenance of a governed identity.

Module Operational Space

EPRM governs:

• evidence preservation,
• provenance evidence,
• governance records,
• supporting documentation,
• evidence integrity,
• historical evidence,
• evidence continuity,
• identity evidence preservation.

Module Function

The module applies wherever organizations must preserve evidence
supporting the provenance and governance history of a
governed identity.

Minimum Implementation Framework

1. Define the Evidence Object

Identify the governance evidence requiring long-term preservation.

2. Define Preservation Conditions

Establish governance conditions governing evidence retention,
protection, accessibility, integrity, verification, and
lifecycle management.

3. Define Preservation Failure Logic

Identify conditions where evidence becomes lost, altered,
inaccessible, incomplete, corrupted, or governance-invalid.

4. Define Governance Response

Define governance actions for evidence recovery, verification,
restoration, investigation, replacement, or governance escalation.

5. Preserve Evidence Records

Preserve governance evidence, supporting documentation, verification
results, historical records, retention history, and
integrity controls.

Use Case 1 — Enterprise Identity Governance

Scenario

An organization must preserve all documents supporting the governance
history of a strategic enterprise identity.

Application

EPRM protects and manages the evidence throughout the complete
identity lifecycle.

Result

The provenance of the identity remains fully supported by authentic
and verifiable governance evidence.

Use Case 2 — AI Identity Governance

Scenario

A governed AI identity accumulates governance records, approvals,
operational logs, and lifecycle documentation over many years.

Application

EPRM preserves every governance-relevant record supporting the
identity's provenance.

Result

The complete provenance remains evidence-supported, independently
verifiable, and continuously governable.

Canonical Closing Statement

History can be questioned, but preserved evidence can answer. Evidence
Preservation safeguards the documentary foundation that allows the
provenance of a governed identity to remain trustworthy throughout the
complete identity lifecycle.
