Double-clicking a brush in the Brushes panel (or the panel menu's Brush
Options…) opens its options. Calligraphic Brush Options: Angle,
Roundness and Size, each Fixed, Random or Pressure with its Variation,
over live previews of the nib and of a stroke. Bristle Brush Options:
Shape and the bristle sliders. OK runs brush.options; strokes painted
with the brush update.
The Paintbrush records the pen pressure along a stroke (path.freehand
takes [x, y, pressure] points), and a Calligraphic brush with Pressure
variation changes its nib along the stroke, from the value less the
variation at the lightest pressure to the value plus it at the heaviest.
Brushes saved before keep their Random variation. Pen pressure doesn't
reach the app on macOS yet (winit 0.30 reports none there).

Document symbols placed inline in a run of type (beyond Illustrator; like
InDesign inline anchored objects): TextRun.inline holds the symbol, scale and
shift; the run is one U+FFFC laid out as a glyph sized to the art, centred on
the cap height. text.insertInline and Type > Insert Inline Symbol; editing
keeps the graphic whole; canvas, SVG (<use>) and PDF draw the art; Create
Outlines turns it into a symbol instance.
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.
