- Images distort as a raster mesh warp: cut by Fidelity into triangles,
each a clipped image under the affine map of its corners (pieces overlap
slightly, no seams; the renderer paints them without clip layers; SVG
writes the pixels once and <use>s them).
- Symbol instances distort as their symbol's art (the renderer's cache
follows edits to the symbol).
- Distort Appearance bakes strokes (filled outlines) and geometry effects
before bending; Distort Linear Gradients bends linear gradients; Distort
Pattern Fills bends the tiles. Opacity masks of the content bend too.
- Bug fix: a rotated, sheared or reflected warp envelope re-warped along
the page axes. Envelopes now keep their own frame (append-only model
field), so the warp turns with the art; move and scale keep it square.
- Live evaluation shares one set of hooks (vectorcraft_doc::live::Hooks,
vectorcraft_effects::{expand_live, expanded_live_group,
expand_live_deep}) between the canvas, Expand and every exporter.

Every exporter (SVG, PDF, EPS, EMF/WMF, DXF) evaluated live objects with no
text outliner, so type inside an envelope was written undistorted. They now
share vectorcraft_effects::expand_live_deep, which outlines type per run in
each run's paint, as the canvas now does too (it used the first run's paint
for the whole line).

font_props wrote `bold` for any style whose name contained bold, black
or heavy and nothing for the others unless fonts were embedded, so
Semibold came back Bold and Light or Medium came back Regular. It now
writes the style's numeric weight (font_descriptor, from style_weight)
for every writer: 600 for Semibold, 300 for Light, 900 for Black, `bold`
for 700 and nothing for 400. The SVG import already reads these numbers
back to the matching face.

The text import reads <text> from the XML and never looked at
paint-order, so character strokes always painted over the fill. A text
whose characters all share one stroke painted first now gets that
stroke as the object's own stroke below the Characters row (as the
canvas, SVG and PDF export already draw it), with its gradient or
pattern resolved in the document; characters with differing strokes
keep them and the import warns.

usvg knows vector-effect but drops it from the tree it returns, so every
stroke was scaled by its transforms. The importer now records the shapes
that ask for vector-effect="non-scaling-stroke" in its XML prepass (by id)
and gives their strokes and dashes the width they have on screen; type
does the same on its character strokes. Where the width can't be kept
(art in patterns, markers or <use> copies, stretched or skewed type) the
import warns.

The svg crate's new CSS writer (css_rules) gives the CSS web pages style objects
with: rectangles and ellipses as background-color / linear-/radial-gradient(),
border and border-radius; type as font, color, spacing and alignment; shadows,
glows and blur as box-shadow, text-shadow and filter. It shares SVG export's
declarations (transparency, fonts, type spacing, colours, gradient stops), which
moved into svg/src/css.rs. Options: units, absolute position, width and height,
unnamed objects, rasterize unsupported art (as a PNG background-image).
Commands css.selection, css.generate and css.export; UI commands css.copy and
css.exportFile; the CSS Properties panel with a highlighted code view.

SVG has no freeform shading: an object's freeform fill or stroke is now
written as an <image> of the colour field over its painted box, sampled
on the grid the canvas uses (twice the box's size in points), clipped to
the shape or to the stroke's outline, with the fill or stroke opacity and
blend mode on the group. Linked image mode writes the PNG next to the
SVG. Character paints keep the linear approximation (with a warning);
gradients along or across strokes stay vector slices. The grid sizing
moved to the colour crate so the canvas and the export share it.

SVG export writes UTF-8, UTF-16 (big-endian with a byte order mark) or
ISO 8859-1 (other characters as character references) and SVG/SVGZ
open in any of them. The Tiny 1.2 profile (simplified) writes
presentation attributes only and leaves out filters, masks, blend
modes and symbols with warnings. embedFonts embeds the fonts type uses
as @font-face subsets of the characters used, honouring the fonts'
fsType (whole when subsetting is forbidden, left out when embedding
is). New options: encoding, profile, embedFonts (SVG Options dialog,
document.formats); document.serialize also returns dataBase64 for
non-UTF-8 files.

The Links panel lists every image (thumbnail, name, page, missing/modified/embedded
badge) with Show filters, sorting and thumbnail sizes; its buttons and flyout relink
(to a file or a folder), go to, update, edit the original, embed and unembed, show in
folder and open Placement Options. Link Info shows format, colour space, location, ppi
and effective ppi, dimensions, scale, rotation, size and dates. Edit > Edit Original
and the Properties panel's image section reach the same commands.
Engine: links.list, links.goTo, links.embed, links.unembed, links.info and
links.placementOptions; links.relink and links.update now place the new file as the
image's Placement Options say (transforms, bounds, file dimensions, fit, fill, the
alignment point, clip to the old bounds). Model: ImageObject.placement.
UI: links.editOriginal, links.reveal, ui.placementOptionsDialog; Services.open_file
and pick_folder on the desktop.

document.open {path} (and File > Place) find an SVG's relative <image>
links in its folder: raster files stay linked images (LinkInfo with size,
time and hash), SVG files and data: SVGs import as vector art, and a file
that can't be read becomes a placeholder in its box that keeps the link,
with a warning and a missingLinks row (Update Links / Relink read it
later). The SVG library itself reads no file unless given a reader.
Nested clip paths become clip groups in clip groups; undisplayed objects
(display:none) come back hidden; spreadMethod reflect and repeat are
expanded into stops over the painted area (matching resvg). Midpoint stops
and focal points keep folding back as before.

<symbol> with <use> imports as a symbol (named after data-name or its id)
with one instance per <use>; a <use> that shows the symbol differently
(inherited paint, a viewport that cuts it) or that the canvas would paint
differently under its transform stays plain art. feGaussianBlur,
feDropShadow and the usual shadow chains (offset, blur, flood or colour
matrix, composite, merge) become Gaussian Blur, Drop Shadow, Outer/Inner
Glow and Feather effects; other filters are still reported. Export records
the symbol name and the shadow/glow blend mode so export -> import keeps
them. <pattern> keeps importing as a pattern swatch (now tested).

A linked image (`ImageObject.link`, now a LinkInfo: absolute path, path relative to the document,
size, modification time, hash, page; old path strings still load) keeps a low-resolution preview
(`ImageBlob.proxy`, at most 256 px a side) that a native save writes in place of the pixels of
images only linked images show. Opening a native document reads the linked files again, looking
for each at its path, then relative to the document and by name in its folder: missing files
show their preview, modified ones are read again only with Update Links: Automatically.
`document.open` reports `missingLinks`, `modifiedLinks` and `updatedLinks`.
links.check reports each link's status, links.update reads modified files again and
links.relink points images at another file or at same-named files in a folder (each keeps its
bounds; one undo step). In the app, a document opened without its linked files asks about each
(Replace…, Ignore, Apply to All), then offers to update modified links when the preference asks.
The renderer caches previews apart from the file's pixels; the Eyedropper samples previews in
the object's pixel space.

file.info takes and reports the title, author, author title, description,
keywords, rating, copyright status, notice and URL in one undo step, plus
the read-only created (file.new) and modified (every save to a file) dates;
junk values are refused. Document.metadata (DocMetadata) round-trips
natively. PDF export writes author, subject and keywords to the info
dictionary and XMP, PNG export writes tEXt/iTXt chunks, SVG export writes
<desc> and, with the metadata option, every field as Dublin Core. The File
Info dialog (fileInfo, ui.fileInfoDialog) edits it with keyword chips and
star ratings.

The editing data now sits in CDATA inside <metadata> with a hash of the
markup around that element (whitespace between tags and line endings
don't count). document.open restores the native document when the hash
matches (data written without a hash is trusted as before); when another
app changed the SVG, or the data can't be read, it imports the SVG and
says why in its warnings. vectorcraft_svg::editing reports the data and
whether it is intact; editing_data stays. Live effects, symbols and
patterns come back exactly; the import fuzz test now mutates saved SVGs
with editing data and hidden layers.

Symbol instances export as one <symbol> def per symbol and a <use> per
instance. An instance the def can't stand for exactly (stained by its fill,
or a transform under which the canvas paints differently: scaling with
strokes, effects or live objects, turning with effects or brushes, any move
with pattern paints or unlinked masks) is written as its own art, now
stained like the canvas and with its patterns and unlinked masks left on
the page. Symbols nested in themselves stop at a fixed depth.
New SVG option hiddenLayers keeps hidden layers as display:none groups;
document.save (and Save As / Save a Copy) turns it on unless told
otherwise, exports leave hidden layers out. Import shows display:none
layer groups to usvg and marks them hidden, so they reopen hidden
(groups a <use> refers to stay templates). File Info metadata goes through
one Dublin Core list. The symbol stain helper moves to vectorcraft-brush
so the renderer and the SVG writer share it.

svgz is a writable format with the SVG options (document.export,
serialize, save, Export for Screens): exactly the SVG export, gzipped.
SVGZ is recognised by its extension or the gzip magic bytes and opens,
places and pastes like SVG (clipboard.importSvg takes dataBase64 of SVG
or SVGZ); Export As SVG or Save As to a .svgz name writes it
compressed. Gzip lives in the svg crate (pure-Rust flate2, builds for
wasm) and unpacking stops at 512 MB.

Layer Names writes readable ids plus data-name with the original name
whenever the id differs; Minimal writes only the ids definitions need;
Unique prefixes every id and CSS class with a content hash, so SVGs
inlined in one page never collide. Import names objects and layers from
data-name, inkscape:label, serif:id or aria-label.

Character gradients on live type export as url(#…) spanning the
laid-out text (point, area, on-path and outlined type, as on the
canvas); character stroke gradients span the text grown by half the
weight. Identical gradients share one def, and a swatch gradient takes
the swatch's name as its id. Midpoints are written as extra stops marked
data-vc-midpoint, which import turns back into midpoints.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Every laid-out line of type is written at its own position (wraps,
indents, tabs, hyphenation and all caps as on the canvas): a positioned
tspan per style run and, on justified lines, per word. Centred and
right-aligned lines are anchored at their centre or right end, so they
stay aligned in a viewer whose font differs. Leading comes from the
layout's baselines, baseline shift is written as dy, horizontal scale as
textLength, vertical scale as the size, tracking and manual kerning as
letter-spacing. The fewerTspans option (engine and dialog) writes one
positioned tspan per line.

document.export, serialize and save, and the Save As / Save a Copy UI
commands, take the SVG options flat or as svg: {…}: styling
(presentation, style, entities, css), outlineText, images (embed or
link; linked files are written next to the SVG), objectIds (layerNames,
minimal, unique), decimals 1–7, minify, responsive, useArtboards and
range "all" (one SVG per artboard), preserveEditing (the SVG reopens as
the full document) and metadata. Unknown keys are rejected and
document.formats lists every option with its default. Results carry the
SVG writer's warnings.
Save writes SVG to an .svg path and Save again reuses its options.
Export As SVG and Save As / Save a Copy to .svg open SVG Options (first
use: Internal CSS and Responsive, then the last-used choices) with a
read-only code view. Save a Copy no longer retargets the document.

Each <text> is swapped for a placeholder group before usvg runs, so the text keeps its z-order,
parent group, clip, mask, opacity, link and <use> instances, and usvg resolves its gradient and
pattern paints (in text space). <textPath> becomes type on a path (startOffset, side, anchor),
vertical writing-mode type on a vertical path. Per-character x/y/dx/dy/rotate lists become line
breaks (bounded), kerning (absolute x measured against the layout), baseline shift and rotation;
baseline-shift, numeric and relative weights (style names), letter/word spacing, kerning and the
character stroke's cap, join, miter and dashes are kept. The style cascade supports type, #id,
multiple-class, attribute, descendant and child selectors with !important and specificity.
<pattern> paints become pattern swatches. The import fuzz covers the new attributes and CSS.

A pixel (and a unitless user unit) is a point and absolute lengths convert at 72 pt per inch
(`font-size="12pt"` is 12 pt, `1in` is 72 pt); a root size in absolute units keeps the physical
size main already gave it (`210mm` opens as a 595.28 pt artboard, user units being CSS pixels of
it). The document's units follow the unit of the root width (pixels when it has none). Text font
sizes honour their units (em/ex/% relative to the parent size, CSS size keywords), as do text
positions, letter spacing, stroke widths and dashes.

As the branch does for older tests: `panic!("…")` instead of
`unreachable!()` in test code (clippy.toml only allows unwrap, expect and
panic there), and the integration tests main added (CLI file I/O, render
gradient text and stroke geometry, SVG export suites) opt out of the
unwrap/expect/panic lints. No test logic changed.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.
- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
unimplemented and unreachable; clippy.toml allows them in tests, and
integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
the document back and returns EngineError::Internal; a panicking tool is
reset; the MCP server answers with an internal error and keeps serving; the
UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
return Result (JPEG/WebP errors used to write empty files),
FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
README pointer and a PR template checklist.

The Gradient panel's Stroke buttons now work: with the Stroke proxy on a
linear or radial gradient they lay it within the stroke (placed on the
page, as before), along the path (start to end of each subpath) or across
it (left edge to right edge; inside/outside strokes span their visible
side). `paint.editGradient {stroke: true, strokeMode}` sets it (new art
too with nothing selected); `document.inspect` reports
strokeOptions.gradientMode. Model: StrokeLayer.gradient_mode (default
Within, not written).
Shared geometry in effects::stroke::gradient: ribs on the bisectors of
the flattened path (fans round sharp corners, widened under arrowheads,
following width profiles) cut slices each painted with a linear piece of
the gradient (Gradient::span). The canvas and raster export clip them to
the stroke's outline and arrowheads, grown a pixel and composited with
copy so there are no seams and translucent stops paint once. SVG and PDF
write the same slices clipped to the outline, with a warning (new
vectorcraft_svg::export_with_report). Outline Stroke and Expand make
gradient meshes clipped to the outline. Mesh quads now grow along their
edges so thin quads show no seams. Dashes, profiles and arrowheads keep
working in both modes.

Radial gradients show a dashed extent ellipse: its handle across the bar
sets the aspect ratio, the ellipse elsewhere rotates it, and the dot inside
the centre ring drags the focal point (GradientGeom.focal) for an off-centre
radial. paint.setGradientGeom takes aspect (%) and focal ([x,y] | null), and
start/end may be left out; the focal point keeps its place in the ellipse as
the vector, aspect and object transform. It renders as a two-point radial,
exports and imports as SVG fx/fy and PDF two-point radial shadings, expands
to off-centre rings, and travels in gradient params and the native format.

Window > Attributes (Cmd+F11) shows Overprint Fill/Stroke, Show/Don't Show
Center, Reverse Path Direction Off/On, the non-zero / even-odd fill rule,
Image Map, a URL field with recent URLs and a Browser button, and a note.
New commands attributes.set and path.setFillRule; path.reverse takes ids and
reversed; attributes.info reports every value. Objects keep the attributes in
Node.attrs. SVG export wraps linked objects in <a>, and import reads links
back. The canvas draws the centre point of selected objects that show it.

Paint given to a clipping path (paint commands with its id) now shows: its
fill paints inside the clip behind the clipped art and its stroke over the
art, unclipped, on the canvas and in SVG and PDF. Node::clip_paint splits the
clipping path into its fills and its strokes (type: its characters' too) for
all three outputs; the renderer caches the parts per clipping path. Clip group
visual bounds take in the stroke. Make Clipping Mask still leaves the clipping
path unpainted, as the reference app does; Ungroup no longer wipes a painted
clipping path's appearance (Release already kept it).

Exported masks carry data-vectorcraft-mask="noclip invert" (the options that
differ from clipping, not inverted). Import restores the flags and the original
mask art, dropping the backdrop rectangle and inverting filter group that draw
the options in SVG; a single mask object comes back as itself, not wrapped in a
group. Masks from other apps import as before.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Paths and compound paths now measure their visual bounds along their shape:
the body (inside/outside alignment, the width profile's widest point), the
tips of the miter spikes the limit keeps, projecting caps' corners and the
arrowheads' reach. A rectangle's right-angle miters stay within half the
weight (Fit to Selected Art, Rasterize and all-art SVG export get tighter,
exact boxes); Appearance::outset is the conservative reach for anything else.
Clicks hit what the strokes paint: outside strokes outside the path (0.8 x the
weight out), inside ones inside, the profile's width where clicked, caps,
spikes and heads. Click culling keeps a cheap box (hit test 0.34 ms per click
on the 50k-path budget). The subpath/tangent helpers move from the stroke
geometry into vectorcraft_geom::bez so both share them; a cross-check test
holds every painted point of the real stroke geometry inside the bounds and
hittable.

A colour linked to a global or spot swatch keeps a tint (Paint::Solid.tint, 1 by default and
left out of files at 100 %): paint.setFill/setStroke {swatch, tint} apply the swatch at that
percentage, swatch edits recolour every linked colour at its own tint, and Color::tinted
resolves it (CMYK and Gray inks scale, RGB mixes toward white). swatch.new saves a tint as a
tint swatch ("Ink 40%") linked to its base. Spot tints separate as that percentage of their
plate (Separations Preview, PDF Separation value) instead of an ink-ratio guess. Adjust Color
Balance's Global mode (tint) shifts the tints of linked colours. The Color panel shows Tint
mode (the swatch chip, its name and a T slider) for linked colours; the Swatches panel
highlights the tint swatch in use. Gradient stops get the same link and tint fields (the
swatch walks cover them), so GradientStop is no longer Copy.

Freeform gradients carry their own points (colour, opacity, spread) and lines
(Catmull-Rom curves through points), blended by inverse-distance weighting
from each disc of pure colour. paint.editGradient {kind: "freeform", mode?}
places 4+ points inside the shape, coloured along the stops (which follow the
points' colours). The renderer samples the field on a cached colour grid
drawn as an image paint clipped by the fill or stroke. Moves, transforms,
box rebases and warps move the points; old files load unchanged.

With type selected, stroke.set (without an item) gives every run the
weight, cap, join, miter limit and dashes instead of adding an object
stroke; while the Type tool edits text, the Stroke panel styles the
selected characters through text.setRangeStyle `strokeOptions`, and the
panel reads the first run (or the selection's style).
CharStyle gains stroke_cap, stroke_join, stroke_miter_limit and
stroke_dash (defaulted, skipped when default). Character strokes and
object strokes on type now draw through the shared stroke geometry on
the canvas, in PDF and in SVG (live text writes cap/join/miter/dash and
tspans reset what the first run sets; object strokes are drawn on the
glyph outlines), so every stroke option, opacity and blend applies.
Outlines, the Eyedropper and graphic styles keep the options.

A group's or layer's own fills and strokes paint every member's geometry, below or above the
members as the new contents slot (Appearance.contents_index) says; its geometry effects reshape
the members as one piece and its raster effects apply to the composite (one combined shadow),
respecting knockout groups. Type's own fills and strokes paint under or over its characters.
Render, SVG/PDF (via bake) and Expand Appearance evaluate them alike.
Commands: appearance.* / effect.* take target: "object"|"contents" and layer ids;
appearance.moveItem moves the Contents slot (from: "contents") or an item across it
(contents); appearance.targetContents selects a group's members. Graphic styles applied to a
group now style the group itself. The Appearance panel shows Contents/Characters rows that
drag, and double-click to target the members or edit the characters' paint.

layer.clippingMask.toggle {id?} -> {clip}: the top object of the current
layer (or of the one selected group, or of `id`) becomes the clipping path,
unpainted and moved to the bottom so art added later is clipped too; pressing
the button again releases the mask and leaves the path unpainted. One undo
step. The Layers panel button runs it and underlines clipping-path names.
Model: NodeKind::Layer.clip (skipped when false). Clipped layers render, hit
test, bound, and export to SVG and PDF like clip groups (Node::clips /
set_clips); the clip-path helpers are shared with Make/Release Clipping Mask.

color::blend gains blend_rgb (the 16 blend functions, with the 0.3/0.59/0.11
luminance of the non-separable modes), composite (source-over with blending)
and the shared opacity-mask luminance weights. Exported SVG masks take
luminance from sRGB values (color-interpolation="sRGB"), as the canvas does.
Tests: a per-mode table on the canvas (object, fill and group blend modes,
within 1/255; Exclusion 2/255 in the rasteriser's 8-bit pipeline), the same
table through SVG export rendered by resvg, clip and invert masks against the
canvas, and every mode's PDF name read back.

With alignDashes every run between corners and path ends holds a whole number of
periods, scaled to fit, with a dash (or dot) centred on each corner and on both
ends of an open path. It lives in the shared dash generator, so the canvas, SVG
and PDF export (as outlines) and Outline Stroke all draw it.
stroke.set: alignDashes and dashOffset edit the current pattern on their own, and
a new dash array keeps the offset and alignment it replaces. The Stroke panel
turns dashes on fitted to corners (or as last turned off), and its Exact/Fit
buttons send only the flag.

Geometry effects reach objects that aren't paths through their outlines (vectorcraft_effects::
reshape: glyph outlines, evaluated live art, the symbol's art, an image clipped by its reshaped
frame), applied to the whole art as one piece; the renderer caches that art per object and
paints raster effects around it in the same filter layers paths use (shared Renderer::raster_fx,
also used per fill/stroke). Exports bake the reshaped art; SVG writes per-item filters; PDF
warns about raster effects on strokes as well as fills and objects.

New Document.page_isolate / page_knockout, set by
transparency.togglePageIsolatedBlending / togglePageKnockoutGroup {value?}
(one undo step each, saved with the document, reported by
transparency.info) and the Transparency panel menu's check items. The page
renders as an isolated group (top-level blend modes no longer blend with
what lies under the page) and/or a knockout group whose elements are the
layers (neutral layers pass their objects through). PDF and SVG wrap the
page content in an isolated group and write page knockout as soft masks.

Both writers now ask the shared stroke geometry how to write each stroke
(effects::stroke::for_writer): a plain stroke where that is exact, else the
canvas's filled outlines (arrowheads, width profiles, dashes fitted to corners,
dots with round or projecting caps), grouped under the stroke opacity when the
line and its heads overlap. Brushed strokes are written as their brush art.
Inside/outside alignment only applies to closed paths, so open paths export as
centred strokes. The PDF outside-stroke clip frame and the SVG outside mask now
cover the whole stroke reach (miter spikes, projecting caps). SVG stroke
gradients use the same paint box as the canvas. The svg crate docs no longer
claim arrowheads, profiles, brushes and effects are dropped.

New Node.knockout_shape (transparency.set / object.setProps knockoutShape,
reported by transparency.info). In a knockout group such an object knocks
out only as much as its opacity and mask let through (a 50% object knocks
out 50%); otherwise its full coverage knocks out. The renderer, PDF and
SVG masks honour it, and the panel's checkbox is now live.

Knockout Group is now Knockout {Neutral, Off, On} (old files' true loads as
On, false as Neutral). In a knockout group each child erases what the
children below it drew where it paints, then adds itself, so it composites
against the group's backdrop; neutral plain groups pass their children
through to the enclosing knockout group. transparency.set / object.setProps
take knockout "on"|"off"|"neutral"|bool; transparency.info reports the
state. PDF and SVG write knockout groups as nested soft masks with the same
look (PDF warns); the Transparency panel has a tri-state checkbox.
