63# Execute the registered query using its retained lifecycle cursor.
64# Returns System.RunResult plus retained slot/clauses; Registry is inside
65# the RunResult and can be rewrapped as Owner. Success advances cursor to
66# the captured execution tick; completed failure consumes it too. Row transaction
67# rollback and deferred visibility follow Compose/explicit barriers.
