mtlcl410andClaude Opus 5.5 2117186687 M2: the Layers panel presents the configuration's /Order tree (ISO 32000-2 Table 99) ...

The panel listed every group in /OCGs, flat. Table 99 says only the groups
/Order lists are presented, nested arrays as a tree, and a leading text
string in a nested array as a non-selectable label; in the default
configuration /Order defaults to the empty array.

- render: DocInfo::layer_order, rows of LayerRow { depth, item } where an
  item is a layer (index into DocInfo::layers) or a label. A nested array's
  entries are one level deeper than the layer or label before them. At most
  4096 rows, 32 levels and 256 characters a label; an indirect array is read
  once, so cycles end. DocInfo::layers is unchanged: unlisted groups keep
  their state, draw, print and answer layer_set and set-layer actions.
- ui-egui: the Layers panel draws the rows, indented 16 points a level, a
  label as a heading that can't be toggled; the count is the layers shown.
  A document whose /Order lists none says so.
- automation: doc_info reports layer_order.
