Section

branchvalues controls how a parent node's values entry is interpreted:

• "remainder" (default): the parent's values entry is the node's own contribution; its sector size = its value + sum of children's values.
• "total": the parent's values entry is the total including all descendants; the displayed sector equals exactly that value.

Use "total" when your data already encodes the full subtree size. Use "remainder" when your data encodes only the leaf/own contribution.
