Evidence Model

The evidence model describes how the Oryvin system produces traceable operational evidence.

Evidence supports operational verification, auditability, and compliance activities such as HITRUST certification.

Purpose

The purpose of the evidence model is to ensure that operational actions produce verifiable records.

Evidence may include:

workflow execution records
artifact manifests
stored artifacts
infrastructure deployment results

These records demonstrate that documented procedures were executed.

Evidence Sources

Evidence is generated at multiple stages of the Oryvin lifecycle.

Source	Evidence Produced
WEIC	documented intent
Orchestrator	workflow execution logs
DropBoxMini	stored artifact records
Infrastructure	deployment or configuration records

Together these create a complete operational history.

Evidence Chain

Evidence forms a chain connecting documentation to operational outcomes.

Example:

policy defined ↓ procedure documented ↓ workflow executed ↓ artifact produced ↓ artifact stored ↓ operational change applied

This chain supports traceability from policy to implementation.

Artifact Evidence

Artifacts themselves serve as operational evidence.

Each artifact contains metadata describing:

when it was created
which workflow produced it
what files it contains
which system it belongs to

This metadata provides context for operational results.

Logging Evidence

Workflow and infrastructure logs also form part of the evidence record.

Logs may include:

workflow execution details
artifact publication records
infrastructure activity logs

These logs provide additional context for operational actions.

Compliance Use

Evidence generated by the Oryvin system may support:

internal operational reviews
compliance verification
audit preparation
security control validation

The evidence model allows operational activity to be demonstrated through recorded artifacts and logs.

Design Principles

Traceability

Evidence should connect operational outcomes back to documented intent.

Integrity

Evidence records should not be silently modified or overwritten.

Accessibility

Evidence should be retrievable when required for operational or compliance review.
