State changes become durable facts.

Mission, approval, evidence, incident and product transitions retain identity and time.

Event envelope

A durable event answers who, what, when and why.

The envelope supports replay while preserving data and authority boundaries.

Event ID
Unique identity for the immutable observation.
Deduplication and audit
Schema version
Version of the serialized event contract.
Compatibility
Actor
The attributable subject or service that emitted the event.
Identity
Correlation
Groups events belonging to the same mission or incident.
Related work
Causation
Links an event to the event or command that caused it.
Transition explanation
Payload hash
Integrity reference for the serialized payload.
Evidence
Append-only observation

Events record state changes without rewriting prior facts.

Each envelope carries identity, schema version, time, actor, correlation, causation and a payload hash.

Causal graph

Correlation connects a mission; causation explains a transition.

These identifiers support replay and incident analysis without becoming authorization tokens.

Data boundary

Events contain operational evidence, not unnecessary secrets.

Payloads follow classification and minimization rules so observability does not become a secondary credential store.
