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.

Object > Expand… opens a purpose-built dialog (Object, Fill and Stroke
checkboxes, disabled when the selection has nothing for them; Expand
Gradient To: Gradient Mesh or Specify N Objects, default 255). Every
option now does something:
- Object: type to outlines, live shapes to paths, effects baked.
- Stroke: strokes outlined into filled paths.
- Fill: linear/radial gradient fills become N solid rectangles or
concentric ellipses, or a gradient mesh with lines where the colour
changes, inside a clip group shaped like the object; freeform
gradients become a mesh shaped like the object. Colours keep their
stops' colour model. With Fill off gradient fills stay live.
object.expand {} defaults match the dialog (stroke now defaults on);
new query object.expand.info and UI command ui.expandDialog.
Create Gradient Mesh on a gradient-filled object takes the colours the
gradient paints at each point (GradientMesh::for_path_with, from_grid,
highlight).
