- Text in fonts that aren't installed comes in as live type in the fallback font again, named as
before (Helvetica-Bold → Helvetica Bold), not outlines plus pink copies on a non-printing layer.
- The installed face that matches a PDF font is decided once per font from its first comparable
glyph, not per glyph (loading up to 64 faces each time, and switching style mid-line).
- Kangxi radicals are unified only for text from Adobe's CID tables, not ToUnicode maps.
- A line is laid out again only when tracking changed it.
- CidText::of is tested on data that isn't a CID-keyed CFF (embedded fonts are untrusted).
- NOTICE: Adobe CMap resources (BSD-3-Clause) bundled through hayro-cmap.

Japanese PDFs and PDF-compatible .ai files often set text in CID fonts
with no ToUnicode map, in vertical columns, and in fonts the reader
doesn't have. They came in as outlines (or as the wrong characters).
- CID fonts without ToUnicode: the character comes from the font's CFF
charset through the standard CMaps (hayro's `embed-cmaps`); Kangxi
radicals that some generators map to are unified with their ideographs
(⿓ → 龍).
- A glyph becomes live type only when the installed font draws the same
glyph: compared by box with the font of the PDF's PostScript name, or
the closest style of its family (a variable font's named instances),
whose style the type then takes. Otherwise it keeps its outline.
- Vertical columns (WMode 1, glyphs with no horizontal advance) come back
as vertical type, letter spacing as tracking; a single upright glyph is
vertical type too. Horizontal lines get tracking from the glyph
positions the same way.
- Text in a font that isn't installed keeps its outlines (what prints),
with an editable copy in a substitute font, drawn pink, on a
non-printing layer named after the missing fonts (stroke-only glyphs
included).
- Marked content other than a layer's (spans with actual text,
artifacts) no longer ends a line of type: 篳篥・龍笛・笙 came back as
three objects when one character was in a span.
- Tests in tests_live_text.rs and tests_realtext.rs.

A file with several artboards writes, on each page, the art of its
neighbours that reaches the page's box, shifted by its own artboard
spacing. Kept, those copies drew over the art of the page they came from
(a hologram over its card's stripes and title). With several pages, art
wholly outside a page's box now stays with the page it belongs to.

Optional content groups become layers (in paint order, shared by every page)
with their name, default visibility, print usage and lock; art outside them
goes to a layer per page. Art that is off isn't lost: an update appended to
the file drops its /OCProperties so the interpreter draws every group, and
the marked-content sequences found walking the content (checked by tag) route
the art to its group's layer, which comes in hidden. A form hidden by its own
/OC keeps the file as it is. document.open layers: false keeps one layer per
page of only what shows (Save then asks for a name).

Luminosity soft masks become opacity masks (alpha masks as a white copy of
their art; backdrop colour gives Clip, an inverting transfer function Invert;
the PDF export's backdrop and Difference covers read back as the options; a
constant alpha mask is opacity). Transparency groups keep their /I and /K
flags (read by walking the content as the interpreter does). Tiling patterns
become pattern swatches (one per colour for uncoloured ones). Text becomes
point type, one object per line with a run per font and paint, fonts named
from the file (document.open textAs: text | outlines). Patch and triangle
mesh shadings become gradient meshes; gradients drawn through their grey
opacity mask get stop opacity back; shadings that don't extend clip the art.
A rectangular clip around all its art (a form's box) is dropped.

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.

Preserve Editing (on in the VectorCraft Default preset) embeds the
native document in the PDF as an embedded file with a hash of the pages
it was written with. document.open of a PDF, .ai or .ait restores it
exactly (restored: true) and falls back to importing the artwork, with a
first warning saying why, when the pages were changed elsewhere or the
data can't be read; SVG and PDF share that fallback and its warnings.
The legacy drawcraft payload name is read too. vectorcraft_pdf gains
editing(), ImportReport.native and PdfOptions.native.
document.save / file.saveAs / Save a Copy write .ai (format "ai" or an
.ai path): every artboard as a PDF that always carries the document and
takes the PDF options; a restored .ai keeps its path so Save writes .ai
again, and .ait templates open their document untitled. The desktop
save dialog lists the formats Save writes. Choosing a standard turns
Preserve Editing off (PDF/A refuses it), Export for Screens and PDFs of
some artboards leave it out with a warning.

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.

A PostScript file (a .ai saved in an older format or without PDF
compatibility, or an .eps, plain or with a binary header) is refused by any
name with a clear message instead of a parse error (there is no PostScript
importer yet). An .ai whose pages are only placeholder text over the editor's
private data (PieceInfo AIPrivateData) is detected and refused with advice to
save it with PDF compatibility, instead of opening the placeholder.
vectorcraft-pdf: is_postscript(), PdfError::PostScript / PlaceholderOnly.

DeviceCMYK and CMYK ICC colours import as CMYK and a file painted mostly in
CMYK opens as a CMYK document (with CMYK default swatches); DeviceGray
imports as Gray; Separation and DeviceN inks become global spot swatches
(their 100 % colour from the alternate space: CMYK, RGB, Gray or Lab) that
the art links to at its tint, /All links to Registration and process
colorants make CMYK. Shading stops keep their model and ink links the same
way. Inks mixed in one DeviceN colour, or spaces that can't be told apart,
import as RGB (with a warning for the mix).
document.open takes colorMode (rgb | cmyk) to open any file in that mode,
converted as file.documentColorMode does (its conversion is now shared).

Opening or placing a PDF or .ai with several pages or a password shows the
Import PDF / Place PDF dialog: a page preview with page navigation, Pages
(All or a range) when opening, Crop To (Bounding Box, Art, Crop, Trim, Bleed,
Media) and a password prompt for encrypted files.
- vectorcraft-pdf: ImportOptions.pages / crop / password, CropTo, info()
(pages, sizes, rotation, boxes); NeedsPassword / WrongPassword / BadPage
errors; images keyed by content so placed pages merge safely.
- document.open takes pages, page, cropTo (or crop) and password;
document.pdfInfo (query) lists pages and boxes, reports needsPassword and
renders a page thumbnail.
- file.place and file.place.info read only the page placed and take every
PDF box as crop (art, trim, bleed, media besides crop and bounding) and a
password; the UI's File > Place asks with the dialog when no page is given,
keeping Link, Template and the other place params.
- testkit::pdf writes hand-made PDFs with page boxes and RC4 encryption.

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.

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.

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.

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.

A dash pattern with a negative value (for example [-5, 3], from `stroke.set` or a PDF `d`
operator) was handed to the dasher whenever any value was positive. When the values sum to zero
or less the dasher never advances, so rendering the document hung forever (canvas, screenshot,
PNG/JPEG export, `vectorcraft-cli convert`).
PDF (32000-1 §8.4.3.6) and SVG (`stroke-dasharray`) both define such a pattern as invalid and the
stroke as solid. `Dash::is_dashed` now says whether a pattern draws dashes (finite, non-negative,
not all zero), and the renderer, the width-profile outline, the SVG and PDF exporters and the PDF
importer use it, so an invalid pattern is drawn, written and read back as a solid stroke everywhere
(the PDF exporter used to clamp negatives to 0, writing zero-length dashes).
