Activity & History
An application-level chronology for meaningful cross-cutting events that do not belong exclusively to one domain's own history.

Administrative changeMembership, role, integration, import/export, or other household-level event.
System recovery / processing eventCompleted migration, repaired connection, or resolved operational issue when useful to preserve.
Historical boundaryDomain-specific payment, communication, document, or matter history remains with its owning area and can be linked from here rather than duplicated.
Rule: this is not an indiscriminate audit-log dump. The user-facing timeline shows meaningful activity; technical audit evidence and operational logs remain available where their purpose requires them.
