Why: A domain outbox could not correlate its committed event with the host receipt because the bus generated the operation ID after the handler returned.
Evidence: RED-to-GREEN bus and compiled-handler tests; local go test ./... -count=1 and isolated PostgreSQL operation/link checks passed as SELF.
Impact: Expose a host-generated operation ID to handlers and resolve a unique committed audit offset after dispatch; missing receipts remain retryable and ambiguous rows fail closed.

Why: Owner-only command audit cannot prove shared business commits, and button dispatch omitted its authenticated actor.
Evidence: Local go test ./... passed; isolated PostgreSQL cutoff, link, and SQLite-to-PostgreSQL migration receipts are recorded as SELF in the task card.
Impact: Add an optional domain-verified metadata link, exact authorized cross-member read, idempotent storage, actor propagation, and honest PostgreSQL cutoff coverage. Broad audit pagination and other sources remain pending.
