The DirectWrite font lister (#594) was installed in the desktop app only:
`vectorcraft-cli` (convert, run, MCP) didn't see fonts that font services
such as Adobe Fonts load on Windows, so its exports set such type in a
fallback font.
- The CLI shares the app's `system_fonts.rs` and installs it first thing
on Windows (not the win7 build). The text crate stays free of unsafe
code; the CLI denies unsafe code instead of forbidding it, so the
shared module's own allowance applies.

An SVG used as an animation rig lost its hidden alternates and their
rotation pivots: the exporter left hidden objects out (only hidden layers
could be kept), and the importer dropped data-* attributes.
- SVG export: hiddenLayers (on by default for document.save, as before)
now keeps hidden objects too, each written display="none" on its own
element (path, image, text or group). Exports still leave them out
unless asked; the CLI's convert asks, as a conversion keeps the
document.
- An object's own data: ObjectAttributes.data, the data-* attributes in
order (ours, data-name and data-vc-*, aside). The importer keeps them on
the objects and layers they belong to (at most 64 per element), the
exporter writes them back, the native format saves them (missing in
older files), and object.setProps {data: {key: value|null}} sets or
removes them.

Reported: with the Pen there was no way to edit curves in place as Ctrl does in Illustrator on
Windows (Cmd on the Mac), segments couldn't be grabbed, and the curve-editing tools felt slow and
sometimes didn't take a handle.
- Cmd/Ctrl held at a press with any tool but a selection tool now borrows the selection tool in the
engine (Session::pointer), not in the canvas: the selection tool chosen last, or Direct Selection
for the Pen, Curvature and anchor tools until one is chosen. The tool lent to isn't deactivated,
so the Pen goes on drawing its path after the release while that path stays selected; it no
longer draws on another open path selected meanwhile. Agents reach it with pointer_gesture
mods.cmd. With Cmd held the pointer is the borrowed tool's. Choosing a tool or switching
documents mid-gesture gives the tool back first.
- Pen + Alt over a segment of a selected path reshapes it, as the Anchor Point tool does.
- The handles shown are the handles that drag (one helper for Direct Selection, the Anchor Point
tool and Pen + Alt): Direct Selection now drags the handles of a path selected as a whole (as
the Pen leaves it, so Cmd + drag of a handle while drawing works), the Anchor Point tool no
longer grabs handles that Show handles when multiple anchors are selected hides, the nearest
handle wins, and a handle shorter than the tolerance leaves its anchor to be picked. The anchor
tools pick within Selection & Anchor Display > Tolerance instead of a fixed 4 px.
- path.reshapeSegment keeps a smooth anchor at either end smooth (its other handle turns with the
moved one) instead of kinking it.
- A dragged handle gathered its smart guide targets from the whole document on every pointer move
(21 ms per move on 20,000 paths): HandleSnap now gathers them once per drag (1 ms).
vectorcraft-cli perf measures handle and segment drags on a 5,000-anchor path.
- catalog::is_selection_tool and catalog::edits_anchors replace the UI's own lists.
- Tests in tools, engine and MCP (headless pointer_gesture); docs/mcp.md, control-protocol.md,
ROADMAP.

Discord feedback: "EPS files are always rasterized: they open as bitmaps, in
other programs as vectors". Every EPS saved by Illustrator 2026 fell back to
its TIFF preview (`gcheck` was unknown), and cairo/Inkscape files stopped at
their first image (`status`), dropped masked images (ImageType 3) and failed
on mesh gradients; the warning didn't say where the program failed.
Fallback never silent:
- The warning names the PostScript error, the operator that raised it and
the named procedures it ran in, innermost first ("a PostScript error
(typecheck in `add`), in `inner` in `outer`"); errors caught by `stopped`
aren't reported. It reaches the status bar, document.open, app.open and
file.open (which now return document.open's result, so MCP's open_file over
the control channel gets it), and `vectorcraft-cli info` ("warnings").
- A file whose PostScript can't be read opens as its TIFF preview, else its
Windows metafile preview (as vectors, scaled to the bounding box), else its
EPSI bitmap. es @msg rows for the new messages.
Interpreter:
- Operators programs probe or use: gcheck/scheck, rootfont,
currentcolorrendering, currenthsbcolor, status, token, read,
bytesavailable, fileposition/setfileposition, resetfile, write*, pdfmark
(marks dropped, as Ghostscript does), execform, nulldevice, strokepath,
pathforall, user paths (ufill/ueofill/ustroke/uappend/upath/setbbox, the
encoded form too), setcachedevice2, findcolorrendering, cache, device and
VM queries, revision; (%stdout) (w) file gives a sink.
- `//name` is replaced by its value when read, inside procedures too.
- Tiling patterns become pattern swatches (their PaintProc drawn in pattern
space, one cell; uncoloured ones in the colour under them; makepattern
copies share one swatch); nested patterns stop at 8 levels.
- Type 3 fonts draw their glyphs (BuildGlyph/BuildChar, widths from
setcachedevice/setcharwidth) as outlines grouped per string, spaced by
ashow/widthshow/awidthshow/xshow/yshow/xyshow/kshow; glyphshow and
stringwidth/cshow use them.
- Shadings of types 1 and 4-7 become gradient meshes (data from arrays,
strings or files, packed or not, flags sharing edges), as fills through a
shading pattern too; sampled functions (type 0) are evaluated;
GradientMesh::coons/triangle are shared with PDF import.
- ImageType 3 masked images, interleaved by sample, by row or in separate
sources; ReusableStreamDecode reads its data when made; Flate/LZW PNG and
TIFF predictors.
- Bounded: DeviceN at 32 inks, sampled functions at 2^24 samples and 32
outputs, 4096 patches a shading, strokepath ignores dashes finer than 1e5
pieces, Type 3 glyphs nest 8 deep (a glyph that shows itself overflowed the
stack before the limit), 64-bit index maths for 32-bit targets.
Tests: a synthetic program per generator (cairo/Inkscape, its Type 3 fonts,
matplotlib, CorelDRAW, Affinity, LibreOffice, Ghostscript eps2write,
Illustrator procsets), meshes and function shadings, masked images, fault
messages, probing operators, metafile/EPSI previews, `//name`, user paths,
hostile patterns/glyphs/shadings (run against main, 12 of the 14 generator
and feature tests fail; CorelDRAW- and LibreOffice-style programs already
read there). The import fuzz vocabulary covers the new operators. Checked
against real files made here with Inkscape 1.4 (cairo) and Illustrator 2026
(its own format and the CS-to-CC compatibility formats; all fell back or
stopped early on main and open as vectors now; its Illustrator 8 format
needs the next commit); those files aren't committed.

document.inspect takes the same {depth?, childLimit?} slicing as
document.node (a depth-0 read is the layer skeleton), and document.find
{name?|kind?|text?, limit?} locates nodes across the tree with their
ancestor paths and a total. docs/mcp.md documents the drill-down recipe;
the CLI stdio sweep covers both.
`depth` / `childLimit` without `summary: true` used to return the whole
full-JSON subtree silently; it is now an invalid-params error. docs/mcp.md
describes the slice parameters and childCount, the engine test covers
fractional values, unsliced reads and limits past the tree, and the CLI
stdio sweep reads a sliced group through run_command.

The export tool's description, the docs' open_file and export rows and the
CLI's run/convert usage listed only some formats. The CLI usage now prints
the writable extensions next to the readable ones, both generated from the
format table (export_extensions), the export tool points to its generated
format enum, and the docs name EPS, DXF, EMF, WMF, SVGZ and templates.

The server answered tools/* and two fixed resources and nothing else, and
resources/templates/list returned an empty array. This adds the rest of the surface a
client can actually use, against 2025-06-18.
- prompts/list and prompts/get: five workflows (poster, icon-set, recolor,
trace-and-style, export-set) with templated arguments. A missing required argument
is -32602 and names itself.
- resources/templates/list, and resources/read for the templates: object/{id},
command/{id}, effect/{id}, swatch/{name}. Reading one thing at a time instead of
vectorcraft://document/json, which on a real document is thousands of lines an agent
pays for again on every change.
- completion/complete for prompt arguments and template variables, ranked prefix
first, capped at 100 with total and hasMore. The values are read live, so a suggested
format, effect id, command id, trace preset, swatch or object id is one the engine
has.
- logging/setLevel and notifications/message. Nothing installed a log::Log before, so
the engine's log::debug! calls went nowhere; this is the sink, silent until asked.
Installing it is vectorcraft-cli's job rather than the library's, so an embedder
that already has a logger keeps it.
docs/mcp.md gains a Protocol section with the capability table and a Not implemented
section: subscriptions, progress, cancellation, sampling, elicitation and Streamable
HTTP all need the transport to interleave reads, which this one does not — handle_line
answers a line with a reply, so it neither reads an incoming cancellation nor can write
progress before the reply it belongs to.
62 tests (50 unit, 12 property/fuzz). protocol_props.rs gained five: prompts survive
junk arguments, completion/complete never panics and always answers at most 100
string values with a consistent hasMore, every template reads or fails cleanly, and
prompts/completions/templates are swept with junk params while asserting the document
comes back byte-identical.
ROADMAP: one bullet under Automation in Shipped so far and the changelog line. The
parity table and the gap list are untouched — MCP is agent automation, so feature
parity does not move.
`vectorcraft-cli commands | head -1` panicked and exited with status 101:
thread 'main' panicked at library/std/src/io/stdio.rs:1168:9:
failed printing to stdout: Broken pipe (os error 32)
println! and print! panic when stdout is closed. Output now goes through
outln! and out!, which end the program with status 0 on a broken pipe (the
reader has what it wanted) and report any other write error on stderr with
status 1.

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.
