bflatastic ffc60d5ff8 M4.59: pattern strokes and freeform gradients keep their look in PDF
Pattern strokes are written as the pattern's tiles clipped to the stroke's
outline (dashes, caps, profile, arrowheads and alignment included) instead
of mid-grey; freeform gradients on fills, strokes and type as an image of
their colour field at the document raster effects resolution, clipped to
what they paint, instead of their average colour. Both read back within
2% of the canvas at 150 ppi with no warning. Text strokes are covered for
cap, miter limit, dash array and alignment; knockout groups keep their
soft-masked form with a warning. The freeform box and grid sampling are
shared with the renderer.

bflatastic e967c31be6 M4.58: raster effects in PDF on every kind of object
PDF export now renders the shadows, glows, blurs and feathers of groups,
layers, type, images, symbol instances, live objects and single fills and
strokes (and those inside opacity masks, symbol definitions and pattern
tiles) as images at the document raster effects resolution, instead of
leaving them out with a warning. Shadows and outer glows go under the
untouched vector art; a path whose fills or strokes carry effects is
written as one piece per fill and stroke. Expand Appearance shares the
image helpers (moved to rasterfx.rs); effect images now cover what the
renderer paints (members' shadows included).

bflatastic ac77b52ad3 M4.49: PNG-8 and GIF export with a palette quantizer and dithering
document.export {format: "png8" | "gif"} reduces the art to a palette of at most `colors`
(2–256) entries: median cut over a 15-bit histogram refined by k-means (perceptual,
selective or adaptive weighting), or the web-safe, black-and-white or grey palettes; art
with that many colours or fewer keeps them exactly. Dithering is Floyd–Steinberg diffusion,
an 8×8 ordered pattern or noise, with an amount. Pixels under half opacity become one
transparent entry; partly transparent edges blend over the matte. PNG-8 is an indexed PNG
(PLTE, tRNS, 1–8 bits per pixel, Adam7); GIF is a GIF89a (optionally interlaced). Both are in
document.formats, Export As (PNG-8 / GIF Options dialogs) and Export for Screens.
document.formats' writable list and the MCP export tool's format enum gain gif and png8
(their tests list them).

bflatastic ba4ed2ff93 M4.48: JPEG Options — RGB/CMYK/gray, baseline/optimized/progressive, embedded ICC profiles and image maps
document.export {format: "jpg"} takes colorModel (rgb|cmyk|gray), quality 0–100, method
(baseline|optimized|progressive), scans (3–5), embedIcc and imageMap (none|client|server).
JPEGs are written with jpeg-encoder. CMYK files hold ink amounts drawn as the renderer's ink
planes, so CMYK colours keep their inks (black type stays black ink alone). Profiles are made
in code from the CMS (cms::icc_bytes): the RGB spaces from their primaries, the CMYK spaces as
Lab lookup tables sampled from their model, a grey with sRGB's tone curve, and loaded
profiles as loaded. Image maps write <stem>.html or <stem>.map beside the image for objects
with a URL and an Image Map shape. The JPEG Options dialog gains Color Model, Quality 0–10,
Method and Scans, Image Map and Embed ICC Profile; CMYK documents default to CMYK.

bflatastic 2e5ec7b251 M4.53: Linked images remember their file and keep a preview; missing links ask Replace or Ignore, modified ones follow Update Links
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.

bflatastic 6a446b4fa3 M4.55: File Info with author, description, keyword chips, rating and copyright, written to SVG, PDF and PNG
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.

bflatastic 950a941003 M4.33: Export As with Use Artboards (All or a range) and art bounds
File > Export > Export As... (file.exportAs) picks any writable format and Use Artboards: All
or a range writes one file per artboard, <file>-<artboard>.<ext> (a PDF keeps them as pages);
off, the export covers the bounds of the visible art (an artless document is refused before the
save dialog). The format's options dialog follows: PNG/JPEG/WebP Options, SVG Options, or Save
PDF for artboards as pages. document.export takes useArtboards for raster formats (true: one
file per chosen artboard, default all) and PDF (false: the art's bounds), and the app's exports
return every file written and the encoder's warnings.

bflatastic 157724279f M4.34: raster export options and PNG Options — resolution, background, anti-aliasing, interlacing
PNG is written by an in-code chunk writer with the resolution in pHYs and optional Adam7
interlacing (JPEG stores the resolution in JFIF). document.export takes ppi (72/150/300/other,
wins over scale), background (transparent, white, black or a colour) and antiAlias (none, art,
type: text snapped to whole pixels); Export for Screens rows take them too (plus one top-level
antiAlias, and a row's ppi names its @Nx suffix), and so does object.rasterize. Hard edges stay
hard in every offscreen pass (groups, masks, filters), whatever the thread count.
RenderOptions.anti_alias and render::encode::RasterExportOptions; PNG/JPEG/WebP Options dialog
(pngOptions/jpgOptions/webpOptions) after File > Export As PNG.

bflatastic 370c6e2fc0 M4.39: SVG symbols as <symbol>/<use>, hidden layers on Save, Dublin Core metadata
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.

bflatastic d527349f5a M4.20: Document Setup with bleed, transparency grid, paper and type options
File > Document Setup is a tabbed dialog over one engine command,
document.setup (no params: a query; any keys: one undo step;
document.setUnits stays as the units alias).

- General: units, bleed (four sides with a link toggle), Edit Artboards,
  Show Images in Outline Mode (greyscale pixels under the frame),
  Highlight Substituted Fonts/Glyphs (pink boxes on screen only).
- Transparency: grid size and colour presets or custom colours, Simulate
  Colored Paper, the flattener preset (built-in or saved) and Discard
  White Overprint (Overprint Preview keeps white overprints visible).
- Type: language with its quotes, Use Typographer's Quotes for the Type
  tool and Smart Punctuation, superscript/subscript size and position and
  small caps size (Character panel position/smallCaps; changing the
  setup restyles the text in the same undo step), text export (SVG text
  as text or outlines by default).
- The canvas draws a red bleed outline and the grid in the document's
  colours and cell size as one textured quad, also in rotated views; a
  white Background Contents exports raster formats opaque.

Model: Document.setup (DocSetup, defaulted, skipped when default) and
CharStyle position/small_caps; old files load unchanged.
tests_transparencygrid's helper now finds the grid by its texture (the
grid is one textured mesh instead of per-cell rectangles).

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

Brandon Thomas 3e323bfa2a Robustness: VectorCraft never crashes — no panics in shipped code
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.

bflatastic 025d758abe M3.83: gradients within, along or across a stroke
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.

bflatastic d8eff17b9f M3.98: radial annotator extent ellipse, aspect handle and off-centre focal point
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.

bflatastic 9537eca5f7 M3.90: blend modes and opacity composite inks in CMYK documents
A CMYK document that shows transparency is drawn once per ink plane
(complemented C, M, Y; complemented K as a grey) so every blend mode,
opacity, group, knockout and effect composites inks, PDF-style; the
planes' inks are shown through the working CMYK profile (cached 4-D XYZ
table). Cyan multiplied over magenta now shows C100 M100. Opacity masks
keep screen luminance; RGB colours and placed images are separated
first. RGB documents and opaque CMYK documents keep the screen-colour
path.

PDF export of CMYK documents writes its transparency groups with
/CS /DeviceCMYK (luminosity mask groups stay RGB) and puts top-level
transparency in a non-isolated page-wide group so it blends in CMYK too.
Flatten Transparency composites CMYK documents ink by ink and makes CMYK
regions. Non-separable modes no longer give NaN for greys.

bflatastic ea61d34a93 M3.85: spot colours defined in Lab, with Spot Colors options for Lab values or CMYK equivalents
Colours gain a CIE Lab model (`Color::Lab {l,a,b}`, serde tag `lab`), handled through the
CMS (display, separation, conversions, gamut), tints (toward paper white), keep_model, harmonies,
recolouring, blends, Info and the Color panel. Swatch Options gets a Lab mode
(`swatch.edit {mode: "lab"}` / `{color: {l,a,b}}`), and colour params accept `{l,a,b}`.

Swatches panel → Spot Colors… (`ui.spotColors`, dialog `spotColors`) runs `swatch.spotOptions
{useLab}` (Document.spot_use_lab, default on): Lab spot colours show and separate from their Lab
values, or art linked to them takes their working-CMYK equivalents, as one undo step. PDF export
writes Lab spot inks as Separation spaces with a Lab alternate (tint function from paper white),
or a DeviceCMYK one with CMYK equivalents.

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).

bflatastic b2ececc7b4 M3.59: tints of global and spot colours, tint swatches and Global colour balance
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.

bflatastic 323b178ea7 M3.40: stroke on type — the Stroke panel edits the characters' stroke
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

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.

bflatastic 8a837fd4b9 M3.68: groups, layers and type have their own fills, strokes and effects, with Contents and Characters rows
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.

bflatastic 54427d7a92 M3.74: blending inside a group reaches the art below unless the group isolates it
On screen, a group (or object) with opacity, a blend mode, an opacity mask or
knockout whose content blends is drawn offscreen over a copy of its backdrop
and mixed back in by its opacity, mask and clip (a group blend mode then
applies to the backdrop-free result, as PDF defines it). Isolate Blending keeps
the content starting from transparency. Clip groups no longer isolate their
children (blending content is clipped per drawing), and non-isolated knockout
groups composite their elements against the art below the group. Groups
without blending inside still render as plain layers.

In PDF, such groups are written as non-isolated transparency groups (a
constant-alpha soft mask instead of the writer's isolated opacity group),
knockout groups included.

Fill and stroke layers (and type characters' fill and stroke) carry an
overprint flag. object.setOverprint {fill?, stroke?, item?, ids?} sets it
(groups: their contents; type: its characters too; one undo step, none when
nothing changes) and attributes.info reads it back (null where mixed).
Overprint Preview and Separations Preview draw overprinting fills and strokes
with Multiply. The old Document.unknown["overprintBlack"] id list migrates to
the new flags on load; Overprint Black now sets the flags.

bflatastic 454c5f8620 M3.39: width profiles follow the path through dashes, and their corners take the join
Each dash and dot of a profile stroke is as wide as the profile where it sits
along the whole path (before, dashes dropped the profile). Corners of profile
strokes take the stroke's miter (within the miter limit), round or bevel join on
the outer side and stay clean on the inner side, instead of a miter clamped at
4x; smooth points of curves bend round. Canvas, SVG/PDF outlines and Outline
Stroke share the geometry.

bflatastic 42ad4540b7 M3.38: dashes fitted to corners and path ends, a flag of their own that keeps the offset
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.

bflatastic 0f1565aed2 M3.43: effects render on type, placed images, symbol instances, blends, envelopes, meshes and repeats; a fill or stroke's own raster effects render and export as SVG filters on that element
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.

bflatastic 039c0cbef7 M3.48: Page Isolated Blending and Page Knockout Group
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.

bflatastic c95098d15a M3.47: opacity and opacity mask can define an object's knockout shape
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.

bflatastic 6e0af835c6 M3.46: three-state knockout groups (on, neutral, off) render, export and edit
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.

bflatastic 18d870c7df M3.37: Outline Stroke and the live Outline Stroke effect outline strokes as the canvas paints them
Outline Stroke (and the stroke part of Expand) now builds each stroke from the
shared canvas geometry: dash shapes, arrowheads, width profiles and inside/outside
alignment, united into one clean path (pathops::stroke_region). Every stroke item
is outlined in paint order (runs of fills stay on copies of the path), stroke
opacity, blend mode and effects move to the new fill, and brushed strokes become
their brush art. The live Effect > Path > Outline Stroke outlines the stroke it
sits on (on a fill or the object: the top stroke) with that stroke's cap, join,
dashes, alignment, profile, arrowheads and weight: GeomContext now carries the
stroke and the fill rule, built per item by the renderer, export baking and
Expand Appearance.

bflatastic 4f685be57a M3.26: clipping sets with any clip shape
Clip groups clip by compound paths (with their holes), even-odd paths, text
outlines and groups (the union of their members) on screen, in raster
export, in SVG and in PDF alike, through one shared region:
Node::clip_outline (the model walk) and effects::clip_outline (text
outlined, several shapes united), cached per clipping path in the
renderer. Nothing to clip by hides the clipped art everywhere, and clicks
hit a clip group only inside its clipping region. Make Clipping Mask takes
a compound path or text object on top (it loses its paint) and Release
gives it back unchanged in kind.
