SPECIFICATION · AXIA.TRUST.V1

Event Taxonomy

Normative catalog of lifecycle event types recorded in the Axia trust ledger.

1. Normative rules

Public lifecycle events MUST be append-only.

Implementations MUST assign exactly one visibility, evidence_class and evidence_strength per event.

Events with visibility internal MUST NOT be exposed to anonymous verifiers.

Event types MUST NOT be reused with altered semantics; new semantics MUST introduce a new event type.
