Every category amount is a reported EDINET XBRL fact. Nodes described as arithmetic bridges are calculated residuals and do not imply a separately reported filing line.
Labels and narrative explain the filing. A category marked “arithmetic bridge” or “residual” is calculated from reported totals, rather than a separately reported line.
