The Pick Color From Artwork line in docs/target-app-parity.md quoted a
sentence from the reference app's Shape Builder combine page. The line
now links the page and describes the rule without quoting it.
Hyphenation... and Justification... already shipped upstream (#2310,
#2755). This ports the part of the archived fork PR #10 that upstream
lacked: a paragraph's Justification > Auto Leading now also sets
- the Leading the Character (and Properties) panel shows for Auto type,
blank where the selected paragraphs differ;
- the leading Alt+Up/Down (type.step) steps from, per paragraph (a run
spanning paragraphs is split so each takes its own);
- the lines Fill with Placeholder Text counts in area type.
ParaStyle::effective_leading mirrors the layout (exactly
CharStyle::effective_leading at the default 120%). Tests in doc, engine
and ui-egui; parity docs no longer list Hyphenation/Justification as
missing.

A Shape Builder drag merged only the regions the pointer passed over,
and the tool did not read Shift. The reference app's Shape Builder page
describes a Shift-drag that draws a rectangular marquee to merge many
paths at once.
With Shift held at the press, the drag now draws a rectangular marquee
from where it started to the pointer. The regions it reaches are shaded
while it is drawn and merge into one shape on release; with Alt also
held at the press, they are deleted. The marquee reaches each region
whose outline crosses it or has an anchor inside it, and the region that
holds the whole marquee. A Shift-click that does not move is a click,
and a drag without Shift works as before. With In Merge Mode, Clicking
Stroke Splits the Path on, a Shift-click on a stroke splits it as a
click does; a marquee splits no stroke, and while it is drawn the
pointer does not show scissors and no stroke is highlighted.
shapeBuilder.merge takes the marquee as rect: [x, y, width, height],
where x and y are where the drag started, and points may then be left
out. For Pick Color From Artwork, the corner where the drag started
counts as the drag's first point, and the opposite corner counts as its
last. With rect, splitStroke does not split a stroke.
Docs: docs/mcp.md, docs/target-app-parity.md.
Cause: with Snap to Point, the point of a moved selection that snaps to a
ruler guide is the grabbed point (#1534). Away from an anchor or center
that was the raw pressed spot (select.rs: `grab` fell back to `p`;
direct.rs: a straight segment's `grab: p`, MoveObject's `start`). A press
on a stroke or within the pick tolerance of an edge lies a few pixels
beside the path, so the pressed spot landed on the guide, "align" showed,
and the path stopped that far beside it: 0.096 pt at 3,891% and 0.0099 pt
at 28,757% in the #3701 screenshots, visible only when zoomed in.
Change: `guides::hold_on_path` finds the nearest point of the path (on a
straight segment exactly on its line). `select::hold_point` uses it for a
press on the stroke or outline, or within 6 px of it. The Selection tool
(`State::Moving::hold`), Direct and Group Selection moves
(`State::MoveObject::hold`) and Direct Selection's straight-segment drag
(`grab`) snap that point. The move delta still runs from the press, so
nothing jumps. A press in the middle of a fill still snaps the pressed
spot, as Snap to Point is documented to.
Verification: tests_prefs::a_move_held_by_a_paths_stroke_lands_the_path_on_a_ruler_guide
and tests_prefs::a_straight_segment_dragged_by_direct_selection_lands_on_a_ruler_guide
fail without the change (edge 0.0257 pt and anchors -0.0052 pt off the
guide) and pass with it (|gap| < 1e-9 pt). A headless egui/wgpu render at
3,891% and 28,757% puts the guide, the selection outline and the centre of
the 1 pt stroke band in the same pixel column. cargo xtask ci: all 10
steps passed; 9429 tests passed, 0 failed.
A filter plug-in had nowhere to keep settings that belong to the whole
document rather than to one object, such as the pens a plotter holds or
a machine profile: it could only ask for them again on every run.
- A filter's output may hold documentData: any JSON of at most 1 MiB
(objects::MAX_DOCUMENT_DATA) that replaces what the plug-in keeps with
the document, null removing it, in the same undo step as its objects
(objects::decode_output). Too much refuses the output and the
document stays as it was.
- A filter gets it back in _context.documentData (null until it keeps
something). A filter reads and writes only its own.
- It is the document's foreign data, Document::unknown["pluginData"] by
plug-in id (vectorcraft_doc::plugin_data), where the perspective grid
and the brushes keep theirs. So the native file needs no section of
its own for it, and hosts from before keep it when they save. An
exporter is given the whole document, so it can read every
plug-in's. Nothing else lists it, as the reference app's Document
Info lists no plug-in data.
A live effect isn't given it: its geometry is worked out from the
object alone wherever it is drawn.
Tests: plugin_data.rs (each plug-in its own entry, forgetting what isn't
kept copies nothing, a damaged value holds nothing), objects/tests.rs
(kept, forgotten, refused over the limit), tests_plugins.rs (one undo
step with the objects, read back, not given to another filter, kept by
the native file among its foreign data, refused over the limit with the
document unchanged, null removes it) and tests/plugin_export.rs (an
exporter finds another plug-in's). The size error has its row in each complete
catalog (COMPLETE_MESSAGES).

The planar map found each edge's source input by scanning every input
segment, and the face around each hole or merge point by scanning every
face, so it was quadratic in the segments; the Shape Builder therefore
gave up past 4096 segments (traced or type outlines) and offered whole
shapes. Index outline segments and faces by bounds on both axes
(RectIndex), walk an edge's segments lazily when finding its leaving
angle, and raise SHAPE_BUILDER_MAX_SEGMENTS to 65,536. Divide with open
paths shares the cap; its cap test now follows the constant.
Tests: a 20,000-segment blob cut by two lines, a 300-line hatch, the
index against a brute-force scan, and the existing cap test at the new
cap. Progress docs updated (G11, parity evidence, roadmap).

Review follow-up (CodeRabbit): the kept 2026-10-05 assessment still read
"raster effects (~20%)" with no pointer, unlike the other rows of that
table this PR annotated. It now notes the 57/57 filters and the Effect
Gallery (#2883) and points to the area table, leaving the historical
number as it was.
Illustrator 30.0's Method choice in the Gradient panel
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-perceptual-interpolation-in-gradients.html).
- paint.editGradient takes `method: classic|perceptual` (one undo step);
paint.setFill/setStroke take it in `gradient`, and gradient params (swatches,
copied paints) carry it when Perceptual. Anything else is refused without
editing. One edit can set `method` and `dither` together.
- The Gradient panel shows a Method menu (Classic, Perceptual) for linear and
radial gradients, dimmed without a gradient; the Dither box stays under the
stops.
- i18n: "Perceptual" where a complete catalog lacked it, and the `method`
error in all 24 catalogs.
- Docs: G13 (estimate 14–24 h → 13–23 h, after Dither's 15–25 h → 14–24 h),
target-app-parity (row and evidence), ui-parity, mcp.md, plugins.md.
With the Artboard tool, File › Revert kept the active artboard, but a
command.batch with a file.revert step made artboard 1 the active one.
A batch that switched to another document and back, and the Actions
panel menu's Batch… over a folder whose files it closes or over data
sets with a Revert step, did the same. Each of them starts the tool
afresh and ends in the document it started in, and the app moved the
view to the fresh tool's artboard 1. Only a plain file.revert was
handled, by its command id.
The engine now counts the times switching or closing documents, or
replacing the active one, starts the tool afresh (Session::tool_resets),
and records whether the tool's options were set after that
(Session::tool_set_since_reset). When the count changes during a
command and nothing set the tool's options after it, the app starts
the tool on the active artboard, as it does when a command chooses
another document. When a later step chose the tool's artboards (a
Paste or Cut after the revert), the artboard the tool then has active
becomes the active one.

With Pick Color From Artwork, a Shape Builder merge took the look of
the front-most object over the first covered region the drag touched,
and the current fill when the drag touched only areas no object
covers. The reference app's combine page gives the look of the object
where the drag starts, else of the object where it ends, else of the
topmost selected object.
shapeBuilder.merge now follows that rule: the merged shape takes the
appearance, opacity and blending mode of the front-most of the objects
it is given (the selection by default) under the first point, else of
the one under the last point, else of the front-most of those objects.
A drag from a hole across a gray bar into a red square now gives a red
shape, where it gave the bar's look. A click in an area no selected
object covers, such as a hole that gray bars enclose or a triangle
that lines enclose, takes the front-most selected object's look
instead of the current fill. Pick Color From Color Swatches works as
before. The tool already sends the press point first and the release
point last.

PDF import measured each gap between two glyphs against the larger of
the line's first glyph size and the next glyph's. A word set beside a
much larger one, apart by positioning and no space glyph (a browser's
margin between two sizes), stayed under a fifth of that em: "≤ 4" at
20 pt and "hours" at 8 pt, 3.4 pt apart, came in as "≤ 4hours".
A gap is now measured against the smaller of the two glyphs beside it.
Lines in one size read their gaps as before.

Illustrator 30.0's gradient Dither, from the public documentation
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-dither-in-gradients.html):
a Dither checkbox in the Gradient panel; dither converts the gradient into
pixels with subtle noise, works with gradient fills only, and follows the
Document Raster Effects resolution.
- Gradient gains `dither` (serde default false, written only when on, so
older files open unchanged and new files keep it).
- The renderer draws a dithered linear or radial fill as an image paint: the
gradient sampled a cell per device pixel or finer (quarter-octave steps,
cached per thread), each channel given seeded triangular noise of up to a
level before rounding. Same pixels every run; strokes and undithered fills
draw exactly as before. PNG and other raster exports go through it.
- SVG and PDF write a dithered fill as an image at the document's raster
effects resolution, clipped to the shape (the freeform-gradient path);
characters' fills stay vector gradients in SVG, with a warning.
- paint.editGradient and paint.setFill take `dither`; strokes refuse it.
The Gradient panel's Dither box is dimmed behind the Stroke proxy.
- i18n rows in all 24 catalogs; docs: G13, target-app-parity, ui-parity,
mcp.md, plugins.md.
The File Handling preference Link Placed PDF and .ai Files
(linkPlacedPdf) is removed. File › Place with Link now places a page of
a PDF, .ai or .ait file read as PDF pages as a linked placed document,
as it links a raster image, and link: false embeds the page. Link is on
by default in the Place dialog and in file.place, so a PDF or .ai page
placed from a file, which used to be embedded, is now linked unless
Link is off. A password or textAs: "outlines" still embeds, and so do
EPS and PostScript .ai files.
The Place dialog's Link tooltip describes a PDF or .ai file as a
document.
A .ai file read from its editing data (its PDF part only a placeholder)
finds the files its art places by name, beside it. Package now copies
those files into the same folder as the .ai file, and warns when one has
to be copied under another name.
File › Place with Link kept a link only to raster images and VectorCraft
documents. A PDF, .ai or .ait page was always embedded as a group, so
Update Links never saw a newer version of the file.
A new preference, File Handling › Link Placed PDF and .ai Files
(linkPlacedPdf), is off by default. With it on, Link places the page as
a placed document, as it places a VectorCraft document: the object
keeps the file's bytes, a preview, the page number and the page's box
(crop, art, trim, bleed or media, stored as page_box). Links check,
update and relink it, Break Link and Object › Expand give the group
placing it without Link gives, every output draws the page's vectors,
and saving and reopening keep the link. With the preference off, or
with a password or textAs: "outlines", the page is embedded as before.
EPS and PostScript .ai files are still embedded.
Package copies a placed PDF or .ai file as it is. The Place dialog's
Link tooltip describes a PDF or .ai file as a document while the
preference is on. Relinking a placed document to a file that is not a
VectorCraft document, a PDF or a PDF-compatible .ai file says so.
Docs: docs/mcp.md, docs/target-app-parity.md.
- One budget for the whole read (layers, pixels, characters, table
cells), shared with embedded documents and charged also when their
reading fails; the first reading is dropped before the second.
- Tables: at most 65 536 cells; lines and cell formats that don't
match the grid are left out instead of shifted.
- Paragraph formats matched to runs by binary search; font names
longer than 256 bytes are dropped.
- Overlays: one work budget per import; encoded originals decoded
within their layer's size; table cell outlines recoloured too.
- Engine: master page copies capped, each page's master found in
linear time, line gaps looked up once per font, the working CMYK
table built once, objects past MAX_COORD left out.
- Embedded content stays with its node; pixel masks under artistic
text are read whole and include stroke reach; gradient overlays on
hidden layers are kept.
- Render: contexts and raster effect images stay within
MAX_RASTER_SIDE per side (vello overflowed near u16::MAX; found by
the new fuzz target).
- Tests: affinity tests/import_limits.rs, feature samples in
import_fuzz.rs, shared builders in engine/tests/support/.

- Strokes set to None no longer import as black 1px strokes.
- Underline and strikethrough are kept.
- Frame text starts at cap height; lines hanging out of a frame make it taller;
mixed-alignment artistic text lines up within its longest line; line breaks
inside a paragraph get no paragraph spacing.
- Table cell text taller than its cell is centred and stays visible.
- Outline effects on stroked shapes are drawn around the stroke.
- CMYK pixel layers go through the document's embedded CMYK profile; without
one, opaque layers stay CMYK.

An export through the desktop save panel kept any typed extension
that names a known format, whatever format it wrote. Export As with
PNG chosen and card.svg typed wrote PNG data to card.svg, and Save as
PDF, Save for Office Documents, Text Export Options, Export Library
and the other writes that go through pick_path did the same.
document.exportSelection with a format suggested and added .png
whatever the format.
Such an extension is now replaced with the written format's, as Save
As has done since #3372: card.svg is written as card.png. An extension
of the written format stays as typed in any letter case (photo.JPEG
for JPEG), Export As SVG (and file.exportAs, file.export.svg) keeps
art.svgz and writes it compressed, and document.exportSelection
without a format still writes the format the typed extension names.
With a format, it suggests and adds that format's extension.

File › Package… read every linked file and font and wrote the package
on the UI thread, so the window stopped responding until the package
was written. For a document that links 50 images of 21 MB each, OK
with Background Export off, which does the same work, takes a median
of 2.25 s in a release build on Windows.
With Enable Background Export on (Preferences › File Handling), OK now
takes the options, the report's Document Info text and a snapshot of
the document, and closes the dialog. The thread that writes background
saves and exports then collects the links and fonts and writes the
package. The same OK takes 0.001 s, and the package holds the same
bytes. A save of unsaved changes that Package starts is written first.
With the preference off, on the web and over MCP and scripts, the
package is made at once with the same reply as before.

With the Artboard tool, Paste and Paste in Place select the pasted
artboards, Cut gives the tool the artboard before the first cut one
(the new first artboard when artboard 1 is cut), and tool.setOption
sets its selected or active artboard. The active artboard, the view's,
stayed where it was, so the navigator showed another artboard than the
tool and the Artboards panel. document.activate and File › Revert
started the tool on artboard 1, while choosing a document's tab starts
it on that document's active artboard.
After a command that changes the artboards the Artboard tool has
selected, the app now makes the tool's active artboard the active one,
as a click with the tool does. After a command that chooses another
document, and after Revert, the tool starts on the document's active
artboard.

Exporting a CMYK document to PDF/X-1a or PDF/X-3 flattens transparency
first. Where the flattener has no single colour (an image with see-through
pixels over a flat fill, gradients, masks, raster effects) it renders the
area into an image, and that image was always an RGB PNG. The PDF writer
then separated it back to CMYK, so CMYK art behind the image came back with
other inks: a C100 M6 Y41 K3 panel printed C75 M14 Y35 K5 under a
transparent logo, with a hard edge against the rest of the panel, and K
moved into C, M and Y.
For files without transparency the flattener's images are opaque and
clipped to their regions anyway, so in a CMYK document it now draws them
as ink amounts over the paper (Renderer::render_region_inks) and stores a
CMYK TIFF, which the PDF writer keeps as DeviceCMYK samples. An area too
large for a CMYK image falls back to the PNG it made before. In-app
Flatten Transparency and other flattening, whose images keep alpha, are
unchanged.
Test: tests_pdfx::pdfx_1a_flattening_keeps_the_inks_behind_an_image_in_a_cmyk_document
exports a CMYK panel under a half see-through PNG to PDF/X-1a, opens the
file again and checks the inks behind the see-through half.

Exercise Selection-tool busy state before takeover and verify it is idle after tab activation, drop, Escape and outside release. Session::set_active already reconstructs the tool via reset_tool_for_doc_switch, so the reported missing-Up busy state does not reproduce and no additional synthetic release is needed.
Narrow documentation to the internal clipboard asserted by the regressions and correct the stationary-pointer sentence. All 10 cargo xtask ci gates pass.
With the Artboard tool, a Ctrl/Cmd double-click on the name of an
artboard that was not selected added it with the first click and took
it out again with the second, so the name field renamed that artboard
alone. The panel menu's Rename opened the field on the active artboard
even when it was not selected. Paste with the Artboard tool leaves it
outside the selection: it selects the pasted artboards and keeps the
active one. Rename then renamed the active artboard alone.
The second click of a Ctrl/Cmd double-click now leaves the row's
artboard selected, and the field renames the selection with it. A
Ctrl/Cmd double-click on a selected row works as before. When the
active artboard is selected, Rename opens the field on its row;
otherwise Rename opens the field on the first selected row.

path.create read closed only when it drew from anchors. Given path
data, {"d": "M0 0 L10 0 L10 10", "closed": "true"} drew the path and
recorded an undo step, while the same closed with anchors fails with
"`closed` must be true or false". shape.rectangularGrid and
shape.polarGrid read rows, columns, concentric and radial given as text
as the count left out, so {"rows": "3"} drew the default 5 horizontal
dividers instead of 3.
path.create now checks closed before it reads d or anchors, and the
grid commands refuse such a count with "`rows` must be a number, not
"3"". Neither command changes the document or its undo history then.
With d, a closed of true, false or null still leaves the path as its
path data draws it.
