 # VectorCraft Roadmap
 
+- PDF.W1: PDF export and print composition use the shared optional writer for configuration, metadata, font preparation and guarded finalization; drawing and output policy remain app-owned.
+
 - UI.5: Shared docking adds tab reordering, docking into other groups, dock splits and resizable floating panel groups. Panel positions and return locations persist with workspaces; the native icon rail and Tools panel remain available.
 
 - UI.4: Dock and floating-panel headers use shared accessible tabs with bounded overflow. Widget-state theme application uses `craft-ui`; all four palettes, font stacks and preferences remain app-owned.
 
 **Stage: alpha** · next: beta, ~13 points (ready for real work ~62% → ~75%, and reliable `.ai` exchange) and ~170–270 h away

+# PDF writer backend
+
+PDF writing uses `craft-pdf` from `storytold/craft-libs`, pinned to
+`c3487320b2d1de657b860b3c8abb44e1f2b32bd8`. Its `write` feature supplies Krilla configuration,
+metadata construction, fallible font preparation and serialization, and native unwind guards.
+The dependency disables default features and enables only `write`.
+
+VectorCraft owns document traversal, drawing, font selection and embedding policy, colour
+conversion, presets, page boxes, layers, editing data, postprocessing and print composition.
+The existing Hayro reader dependencies and editable import adapters keep their current sources.
+Desktop printer submission remains in `craft-print`.
+
+The shared writer vendors Krilla 0.8.2 with an unwind-safe cleanup and poisoning patch.
+The root `[patch.crates-io]` selects that copy from the same immutable revision: Cargo does
+not inherit a dependency workspace's patches. A failed page or surface cleanup poisons the
+backend document, so serialization cannot return an incomplete PDF after unwinding.
+The shared crate's compile-time backend marker and `cargo xtask pdf-deps` (included in CI)
+check that the patched writer is used. Krilla retains its MIT OR Apache-2.0 licensing;
+its upstream provenance and authored patch are recorded in the shared repository.
+
+Export and print construction, drawing and postprocessing run inside the shared native
+unwind guard. These guards do not catch WASM aborts or process-wide allocation failures.
+VectorCraft retains its finite-coordinate checks and the existing behavior that omits art
+outside the writer's supported coordinate range. Font preparation checks the shared
+512 MiB per-font copy limit and variation coordinates before allocation; failure preserves
+VectorCraft's reported outline fallback. The writer is not a peak-memory or runtime budget.

This is not established by the documentation we could find: the public help pages on guides, rulers and the Transform, Control and Properties panels (read again on 2026-10-14) describe selecting and dragging unlocked guides and the panels' X and Y for a selection, not a guide's position in a panel, and the one public statement of it is a user's [community answer](https://community.adobe.com/questions-652/adding-a-new-custom-guide-785586), which is not documentation. It is kept as a convenience pending the owner's decision, with no parity claim and nothing counted towards a score; Select Behind (Ctrl/Cmd-click) tests each object once, so a deep stack of overlapping objects no longer slows it; same objects in the same order (#1571); Commands that take `ids` run on the objects given with nothing selected, over MCP, the control channel and the CLI too (#1577, fixes #1575); Zig Zag spaces its ridges evenly along each segment, so lines and curves get a regular wave in Corner and Smooth (#1558); Warp › Arc (the effect and Envelope › Make with Warp) bends in the object's real proportions: a circular arc with concentric edges and no fold-over at 100%, so Arc on art that isn't square draws differently from before (#1581, fixes #1578); `effect.apply` and `effect.setParams` give an error for a misspelt or wrongly typed effect parameter instead of running the effect with its default (#1623, #1592); Area type in a non-rectangular shape moves a word too wide for the top lines down to the first line that holds it instead of breaking it (#1617, fixes #1615); Stylistic sets (ss01–ss20), stylistic and titling alternates, proportional and lining figures, and superscript and subscript glyphs can be turned on as OpenType features of a character style (`text.setStyle {features}`), and the OpenTypeLine truncated

 - **Fonts:** a font is found by any of its names (family and style in every language of its name table, legacy family/style pairs, PostScript name), so documents from other apps open with the font they name; Find Font and `text.fonts` say for each font whether it was found exactly, by another name, substituted or missing, and how many glyphs are missing. PDF and `.ai` import brings Japanese text back as live type: CID fonts without a ToUnicode map read through the standard CMaps, vertical columns (WMode 1) as vertical type, letter spacing as tracking; a glyph is live type only when the installed font (in the closest style of its family) draws the same glyph, and text in a font that isn't installed comes in as live type shown in the fallback font until the font is installed (exports that draw it — PDF, EPS, EMF/WMF, raster, SVG outlines or embedded fonts — warn that they wrote the fallback font; `textAs: outlines` keeps the PDF's embedded glyphs). Two installed versions of one family and style (a font library keeping an old file beside a new one) both load, the first staying the one the family and style resolve to; PDF and `.ai` import tries each version when the glyphs differ, and type set in a version other than that one names it (`CharStyle::font_version`), which layout, the substituted-glyph highlight, Find Font, Package and Document Info follow. Fonts outside the font folders are listed too: those font services such as Adobe Fonts load on Windows, through DirectWrite, and those apps and font managers register with CoreText on macOS (#579). When a document opens with fonts that aren't available, fonts used only in symbols included, a Missing Fonts dialog lists them after the linked-file questions, with Find Fonts (Type › Find Font on them) and Close. Its Find in Folder… (in Find Font too) searches a folder on several threads, reads only what the font scan reads of font files and skips app packages, the Program Files and ProgramData folders, the system's folders and the app data folders in a home folder; Add Fonts copies the font files the user chooses, suitcase fonts with their resource fork, into VectorCraft's own Fonts folder, which the desktop app and `vectorcraft-cli` read (`text.missingFonts`, `text.findFontFiles`, `text.addFontFiles`). The font scan on Linux also reads the folders fontconfig's configuration lists, such as TeX fonts under `/usr/share/texmf/fonts` (#1548, fixes #1529; not verified on Linux).
   The font database looks up a name that is neither a loaded nor an installed family among the other names of the loaded and installed fonts once for each style it is asked in, and keeps the answer until fonts are added or rescanned. Laying out a story of 1,000 paragraphs set in a font that is not installed, with 400 more fonts loaded, takes a median of 56 to 71 ms instead of 409 to 507 ms on Windows 11 (`CRAFT_FONTS_DIR=<craft-fonts checkout> cargo test --release -p vectorcraft-text --lib missing_font_story_layout_timing -- --ignored --nocapture`).

+  - PDF export and print composition use the optional shared guarded writer ([pdf-backend.md](pdf-backend.md)); app drawing and output policy, the current reader and desktop printer submission remain in their existing layers. Empty and populated metadata key presence is regression-tested, and CI checks the immutable backend source.
   - `.vectorcraft` (lossless JSON, compressed, atomic saves, save down to v1), Save As with a format chooser, Save a Copy, Revert, templates, Data Recovery after a crash (browser tabs hold their copies with Web Locks too, so a background tab's copies are never taken for a crash's, and a tab repairs copies another removed when it resumes: #367), background save and export. The desktop app writes its warnings and errors (graphics adapter, a lost graphics device, panics the guard recovered from) to standard error and to `logs/vectorcraft.log` next to the preferences, the two previous runs kept and each file capped at 16 MiB, so a launch without a terminal still leaves something to attach to a bug report (#465). Native documents with a lot of path data (traced or generated art, in layers, symbols or patterns) are saved as compact JSON, about a fifth of the size; small documents stay pretty-printed (#1492). Saving to a network drive on macOS falls back to a plain fsync when the share refuses a full flush (#1625, part of #1620; not confirmed on a real share), and a save still succeeds when a folder refuses the temporary file, the rename over the document or copying permissions: the content is written elsewhere first and copied in, and a failed copy keeps the temporary file and names it (#1649, part of #1620). A document opened by a relative path finds its relatively linked images, and `vectorcraft-cli convert` lists what reading the input left out as `importWarnings` (#1606, fixes #1604).
   - SVG/SVGZ in and out with SVG Options, Preserve Editing, symbols, filters, rich text and physical units (SVG type under a transform or `viewBox` scale opens at the size it draws at, the scale moved into its size, leading, baseline shift and strokes, a stretch, skew or rotation kept as its transform: #396; a top-level group with a clip path, such as a clipped Inkscape layer, opens as a layer with a clipping mask, its name kept: #420; hidden objects written hidden on Save and `convert`, and `data-*` attributes kept as the objects' own data: #522; top-level groups open as layers named from `data-name`, else the id, also when one more group (a transform on all the art, a `<switch>`) wraps them, hidden ones hidden, and a file whose art sits loose under a root `<svg>` with an id (or `data-name`), as one-layer exports write it, opens with its one layer named from it; nested groups stay groups, except the sublayers VectorCraft writes, marked `data-vc-layer`, and Inkscape sublayers, which open as sublayers in their layer's colour: #372); PDF and PDF-compatible `.ai` in and out (layers, with hidden ones kept hidden with their art and nested ones as sublayers, on pages of up to 64 million operators, art whose layer can't be told going to a hidden, non-printing layer rather than showing or printing: #419; strokes kept live, a fill and a stroke of one outline as one object; a type object's stroke written as each glyph's outline stroked back on the type, so it stays one editable object; lines wrapped in a frame (each wrapped line ending in a space, one left edge, leading and font) back as one area type object, left aligned or justified with its paragraph spacing, where laying it out breaks the lines where the file does; glyphs set apart by gaps wider than a space (a barcode's digit groups) keeping their places; layers stacked as the pages mark them even when one first paints on a later page, art ending a layer's marked content or a clip closing in a later layer kept in its own layer, and layers with no art kept empty: #508; art reaching past a plain PDF's page clipped to its crop box, as PDF viewers show it, each such object in a clip group of its own (a PDF-compatible `.ai` opens whole: #675); a `.ai` on its trim boxes with the bleed boxes round them as the document's bleed, as Crop To › Trim opens a PDF (#1266); masks, editable text with type set along a curve coming back as type on a path, each artboard's art on its own page only, an `.ai`'s white page under its layers left out rather than coming in as art, spot colours, presets, security, marks and bleed, ICC output intents, raster effects, subset fonts, PDF/X, PDF layers, overprint, page thumbnails, fast web view, PDF 1.3). CMYK images keep their ink amounts from PDF import (and from placed CMYK TIFFs) to PDF export: a CMYK JPEG passes through unchanged, others stay CMYK (DeviceCMYK, or ICC-based CMYK in PDF/X-3/X-4) unless the Output settings convert them; the canvas shows them through the working CMYK profile (#320). Overprint is kept from PDF import (opened, the PDF part of an `.ai`, placed) to PDF export: the graphics state's `/OP` and `/op` become the overprint of fills, strokes and type, so a spot colour over a process colour still overprints; a page whose overprint can't be read for certain knocks out with a note, as does `/OPM 0` being read as nonzero overprint (#1388; hand-written fixtures, `pdf/src/tests_import_overprint.rs`). A masked CMYK image (`/SMask`, `/Mask` or a colour key) keeps its inks too, its alpha coming in as a greyscale opacity mask.
     SVG import's style cascade, used for hidden objects, non-scaling strokes and type, tests each element only against the `<style>` rules for its id, its classes and its element name, and the rules whose selector ends in none of these (`*`, `[x]`).

This is not established by the documentation we could find: the public help pages on guides, rulers and the Transform, Control and Properties panels (read again on 2026-10-14) describe selecting and dragging unlocked guides and the panels' X and Y for a selection, not a guide's position in a panel, and the one public statement of it is a user's [community answer](https://community.adobe.com/questions-652/adding-a-new-custom-guide-785586), which is not documentation.
