step.encryption_key_required: Actions make several changing calls but no key encrypts their answers

Actions make several changing calls but no key encrypts their answers.

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

The answers of an action with several changing calls are kept, encrypted, until it commits, so app.jadpo names the SigningKey setting they are encrypted with. The error is reported once, at the first such action:

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}
