Helpdesk Timeline, Audit & Events

Artifact boundaries

Artifact	Purpose	Audience / scope	Event contract?
Ticket state	Current operational truth	Helpdesk reads and reports	No
TicketAuditLog	Action evidence with actor and details	Operational/audit inspection	No
TicketTimeline	Human-readable chronological ticket history	Ticket experience	No
Domain event	In-process domain fact	None implemented	Not implemented
HelpdeskTicketEvent	Cross-service lifecycle snapshot	Integration consumers	Yes
OutboxMessage	Durable delivery envelope	Messaging infrastructure	Persistence model

Audit, timeline and integration rows may be created by the same endpoint, but they have different purposes and retention concerns. Timeline records must not be replayed as contracts without a separately designed transformation.
