Canonical Governance Event Structure

This document defines the minimal conceptual structure of a governance event within Janus systems.

The structure is not a runtime schema. It defines the conceptual fields required for interoperability and deterministic reconstruction.

Event identity

Every governance event SHOULD contain a unique identifier.

Example field:

event_id

Event type

The event type identifies the governance event category.

Examples include:

• OMISSION_DETECTED
• HUMAN_DECISION

Example field:

event_type

Timestamp

The event MUST record the time at which the governance event was produced.

Example field:

timestamp

Evaluation scope reference

Governance events SHOULD reference the evaluation scope in which the event was produced.

Example field:

scope_ref

Schema reference

Governance events SHOULD reference the relevant schema context from SCHEMA_LOG when interpretation depends on schema definitions.

Example field:

schema_ref

Domain references

Governance events SHOULD reference relevant domain records from MANAGEMENT_LOG.

Example field:

management_refs

Evidence references

Governance events SHOULD reference supporting evidence.

Evidence references may include:

• E+ artifacts
• E− omission observations

Example field:

evidence_refs

Optional actor reference

If relevant, the governance event MAY reference the responsible actor or authority.

Example field:

actor_ref

Purpose

This structure allows governance events to remain:

• traceable
• interpretable
• reconstructable

without constraining implementation technologies.
