MtdAdjustableSummaryDto

An adjustable summary (BSAS) HMRC have generated for one income source — the accounting result
of everything filed for the period, which the practice reviews and then adjusts.

Adjustments are deltas, not replacements, and HMRC accept them only once per summary. A
correction therefore means triggering a fresh summary and adjusting that one, which is why the
adjustable flag matters: it gates what the practice may do next.
