Disadvantaged and other-pupils partition the whole and the all-pupils figure is published, so publishing both halves recovers the suppressed one. The mask is applied in the mart rather than the API so no consumer added later can reach an unmasked combination. The R1 test is a warn, not an error: DfE publishes the recoverable combination and the mart's job is to carry it faithfully. Refusing to close the gap is the API's job and the frontend's.
