step.store_required

Action makes several changing calls but writes no store to keep their record in.

Area 12, Jobs and events; not declinable; the next step is usually the human's.

Each changing call is recorded beside the outbox of the store its action writes, so an action that writes none needs events: { store: }:

example
use app { sheets }use bakery/failures { SheetNotKept }use bakery/events { PricesChanged }/// Keeps a supplier's new prices as a sheet, then a copy for the/// accountant.action file_prices(event: PricesChanged) fails SheetNotKept -> Unit {    var sheet: File = attempt sheets.put(encoding.to_utf8(event.price_list), FileType.csv) {        storage_full: SheetNotKept    }    var invoice_copy: File = attempt sheets.put(encoding.to_utf8(event.price_list), FileType.csv) {        storage_full: SheetNotKept    }    assert sheet != invoice_copy}
