raise_negative_gap raised a negative gap from the interior widths only, so a first layer narrower than the gap's size let the second start before it (widths 10, 100 x5 at X 0, 80, 200, 260, 400, 460: the modal -40 gave X 0, -30, 30, ...). The second must start after the first, g > -w(0), in whole pixels floor(-w(0)) + 1. Figma kept the order in every measured run; a narrow first layer was not measured, so this bound keeps the order rather than follow a reading. Test: tidy_tests::a_narrow_first_layer_still_keeps_the_second_after_it.

Shift+Cmd/Ctrl+V pasted into the selected layer's parent at its top-left,
but appended the copies, so they went to the top of the parent's layers
whatever was selected. In an auto layout frame that put them at the end of
the flow, away from the layer they were pasted over.
They now go just above the selected layer, in the copied order: in the
Layers panel the row above it, in an auto layout frame the item after it.
A section pasted over a layer in a frame still goes on the page, on top
of its layers, as before. Paste to replace already kept the replaced
layer's place.

board.mindMap's default x and y came from the view's centre, which is on the page, but x and y are the root's place in its parent: under a section at (1000, 500) the map landed 1000 right and 500 down of the view's centre. The default now takes the centre through the parent's inverse world transform (a parent that can't be inverted gives a non-finite centre, which the coordinate check refuses). Explicit x and y stay parent-local. Tests: two in board_mindmap_tests (a section; a frame turned 30 degrees, with a given place carried through the frame).

inspect.code {language: "tailwind", mobile} dropped every mobile max-width and put the desktop one behind lg:, so a fixed-size layer that is the same size on both frames (a 48 x 48 badge) stretched to the full width below 1024 px. A mobile max-width that equals the desktop one is now kept as a plain class, with no lg: copy. A differing max-width still goes fluid on mobile with the desktop cap behind lg:.
Tests: the issue's two frames (a 1440 and a 390 page, each with a 48 x 48 badge) keep max-w-[48px] unprefixed, and a page-wide banner still gets its lg: cap only. The slashed-names test gave the CTAs frame the same 342 px on both frames, which the new rule rightly keeps, so its desktop frame is now 600 px wide. docs/mcp.md notes the rule.

flutter_line skipped `spacing:` when the main-axis alignment string
contained "Space", but the strings are MainAxisAlignment.spaceBetween,
spaceAround and spaceEvenly (lower-case s), so it never matched and the
gap was written on top of the distribution. It now checks the MainAlign
value itself.

Third Figma run (web app, 2026-11-12): the mean gap rounds half up (X 0, 60, 135, 215 gives 0, 72, 144, 216; 0, 60, 135 gives 0, 68, 136); a tie between repeated gaps takes the smaller; a row is one row group of layers and may overlap along X, a negative gap counting in the mean (X 0, 60, 105, 170 gives 0, 57, 114, 171); a grid is packed along the axis with more groups (2 x 3 by centred columns, 3 x 2 by centred rows); a diagonal, an irregular layout and layers that all overlap are unavailable. The earlier cell rule is removed.
Choices, not measured: a 2 x 2 grid as columns, auto layout flow children unavailable, the 2,000 layer cap, rotated layers by their box, spacing with two layers, no rounding with Snap to pixel grid off. Grid positions along a stack can differ by a pixel from Figma's (it read 52 and 51 for the same mean 51.67).

Measured in Figma's web app on 2026-11-12 (top-level rectangles): a row, a column and a 2 x 3 grid of unequal sizes, eight runs on the gap, and the cases where Tidy up is greyed out (fewer than three layers, overlapping layers). Figma keeps the order, the sizes and the first layer, evens one gap per axis (the most common existing gap, else the mean taken down to a whole number) and tidies a grid by columns.
Choices, not measured: the smaller of two equally common gaps, a mean ending in .5 going down, gaps a pixel apart differing, a diagonal being a row, a grid with an empty place, a grid always read by columns, one overlapping pair making it unavailable, auto layout flow children making it unavailable, the 2,000 layer cap, rotated layers by their box, spacing with two layers, and no rounding with Snap to pixel grid off. A selection that is none of a row, a column or a grid keeps the earlier rule unchanged.
The Design panel's Tidy up row is greyed out with a tip when unavailable; the command then moves nothing and adds no undo step.

inspect.code wrote one `background` per visible fill, so only the last survived. A non-text layer now gets one `background` with every visible fill as a layer, top fill first (a document's fills run bottom to top), joined with ", ". A solid above another fill is `linear-gradient(0deg, c, c)` since CSS allows a plain colour only as the last layer; the bottom solid stays a plain colour (and keeps its variable token); gradients, images and patterns keep their layers. A single fill is unchanged. Text keeps one `color` per fill. Tailwind emits a layered value as one `[background:...]` class. Native targets are unchanged.
Tests: several_fills_are_one_layered_background_top_first, one_solid_fill_stays_a_plain_colour, several_fills_are_one_layered_background_class.

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.

Measured in FigJam's web app on 2026-11-12: a sticky's own toolbar has a text-size menu (Small 16, Medium 24, Large 40, Extra large 64, Huge 96), a fresh sticky is Small = 16 (the 18 of 2026-11-09 did not reproduce), the note grows taller at Huge and shrinks back, a size chosen with two stickies selected sets both, and the sticky tool remembers the last size.
STICKY_TEXT_SIZE is 16 and STICKY_SIZES holds the table. board.setStyle {fontSize} sizes stickies' notes and sets the sticky tool's size (BoardTool.sticky_size); board.sticky takes the tool's size or a fontSize (1 to 1000). The contextual bar shows a size menu (the current name or number, a check on the current entry) when only stickies carry text; shapes keep S/M/L/XL. Docs: boards-parity rows, revision history and status line.
