The engine test now follows the issue: a list typed at 5, saved as .fig and opened, split by Backspace at the start of "b". The REST fixture is a top-level list, the junk sweep reaches the new loop through a listed text layer, and the document crate tests the new rule for nested, bullet, plain and over-deep levels. ParaList gets its doc comment back, and the revision row names the item written with 0.

Figma writes a list's start on every line of the list (measured in Figma's web app, 2026-11-12, from a saved .fig: a list started at 5 has listStartOffset 4 on all its lines, and the item split off by Backspace is written with 0). The import kept every line's value, so after a split the items after it restarted at the old start instead of 1.
The import now keeps a start only on the item where a numbered list starts counting, and gives every item that goes on counting 0, for .fig and REST listStartOffsets alike. The rule is one function in the document model, list_item_starts_counting, which the layout's list numbering now uses too. The export is unchanged and its re-import now equals what went in.
