fx_rate_daily получает строку на каждый календарный день: котировки ЦБ тянутся вперёд (и назад до первой), is_carried это помечает, RUB = 1.0 всегда. Дальше любая сумма конвертируется по курсу СВОЕЙ даты, а не сегодняшнему. Net worth восстанавливается назад от текущего account.balance по транзакциям — ZenMoney отдаёт остаток, а не историю; поэтому сегодняшняя строка совпадает с тем, что показывает ZenMoney, а каждая прошлая с ней согласована. Нет курса — не подстановка, а NULL и строка в metric_data_quality. Туда же попадает то, что шаги заметили по дороге: правило без совпадений, счёт без баланса, перевод через границу net worth.
