File Change Set As Interim

File a held balance sheet as an INTERIM sheet (accountant) — ZET-395.

A balance sheet uploaded as a document that is dated BEFORE the end of its fiscal year (in any year) is not accepted as that year's closing sheet unseen: it is held as a pending balances change set whose summary.interim_question is true, and the caller answers "interim sheet (Zwischenbilanz) or the year's closing sheet?":

• closing sheet → POST .../change-sets/{set_id}/apply (the ordinary consent);
• interim sheet → this call: the sheet is kept (status superseded, still listed, totals.interim: true) and never becomes that year's closing sheet — the next opening, staleness and the consent lifecycle read only accepted/proposed sheets — and the change set is discarded with summary.answer: "interim".

(A sheet in a company's FIRST year, before its opening is posted, asks "founding or closing?" instead — summary.founding_question, answered by .../founding; this call also answers that set, e.g. once the year has been opened; any other held set is refused.) A sheet cannot be the closing sheet while a later-dated sheet of its year exists: one dated before the year's accepted or held sheet is filed as interim at once, and a waiting question is answered "interim" when a later-dated sheet is accepted or held. apply-all never answers either question. 422 invalid.interimBalanceSheet when the set holds no balance sheet or its sheet is dated on the year-end; 409 when the set is no longer pending.
