Vector edit mode can now edit several vector layers at once, and the rest of the vector edit tail
from the public documentation landed. A behaviour suite came first
(`crates/engine/src/vector_multi_behaviour_tests.rs`, 5 behaviour tests with about 30 table rows and
steps, plus a junk-parameter sweep of every `vector.*` command run in multi-edit mode).
- **Multi-edit.** Enter, a double-click or `vector.edit.begin {ids}` with several shapes selected
puts them all in edit mode, converting them in one undo step. The clicked or first one is the
active layer. Pressing another layer's point, handle or segment makes that layer active. Shift-click,
marquee and lasso select points in any layer. Dragging a selected point, the arrows, Delete,
delete and heal, mirroring, smoothing, corner radius and the new cap and join commands reach every
layer's selected points in one undo step. The pen, bend, paint bucket, cut, eraser, join and
position work in the active layer. A click away from every edited layer leaves edit mode.
`vector.edit.state` now reports `layers`, `others` and `handles`.
- **Several handles.** Shift-click Bezier handles to select more than one. Dragging one moves the
others by the same amount. Also available as `vector.edit.select {handles}` and
`vector.edit.moveHandles`. Selected handles are drawn filled.
- **Rounding next to curves.** A sharp point with a corner radius rounds even when one of its
segments is curved. The curve is cut where the arc meets it and keeps the rest of its shape, and
the arc meets each side smoothly (`VectorNetwork::rounded`).
- **A cap and a join per point.** `Vertex` gets optional `cap` and `join` values. When unset, the
layer's apply. The commands are `vector.edit.strokeCap` and `vector.edit.strokeJoin` (`null`
clears). The Design panel's Point section gets End point and Join dropdowns, each with a "Same as
layer" option. The stroke is drawn run by run and each point's own join is drawn over the break
(`figcraft_pathops::stroke_outline_of`, new `points.rs`). This applies to the canvas, PNG and PDF,
and to SVG as outlines. Outline stroke follows it, render bounds count arrowheads from points, and
the stroke cache key includes the points' styles.
- **Pen outside edit mode.** Clicking one of the path's own points (other than the first or last)
connects there and ends the path, as a vector network. With an open vector selected, clicking one
of its end points continues that path in edit mode.
- MCP: headless `key` Enter on shapes now enters vector edit mode, as in the desktop app. The new
commands have Spanish labels, and the new UI string has en and es entries.
- Docs: target-app-parity (area 4: 98%/72% to 99%/73%, 2-4 h to 1-3 h; area 20: 80%/55% to
88%/60%, 2-5 h to 1-3 h), ROADMAP, gaps (gap 9 is down to tablet pressure on macOS and Linux; the
gap 13 note is updated), ui-parity and mcp.md. Totals are recomputed by the doc's method, because
rows added since the last recompute had left them stale. Feature breadth is now ~83% and ready for
real work ~52%. Mainstream stays at ~49% (49.7%, rounded down). Full parity goes from
~306-595 h to ~294-572 h.
**A shapes and vector behaviour suite written from the public documentation, and fixes for every divergence it found.** Each documented rule (drawing with Shift and Alt, corner radius and which layers take one, point counts and star ratios, arcs, stroke joins and the miter angle, caps per end, boolean results and the look they take, flatten and outline stroke; entering and leaving vector edit mode, the pen, selecting points and segments, deleting vs. delete and heal, handle mirroring, the bend, paint bucket, cut, join and eraser tools, nudging and undo steps, what converting a shape keeps) is a table row or a step with what the rule implies and a one-line derivation; where the documentation is silent the row says so and pins today's behaviour.
**Fixes**
- **Rounded vector points were stored but never drawn**: a point's corner radius (edit mode's Corner radius field, `vector.edit.cornerRadius`) now rounds the corner between two straight segments on the canvas, in hit testing, booleans and every export (`VectorNetwork::rounded`, used by the fill and stroke paths); the radius shrinks to fit half of each segment, like a polygon's corners. A vector layer's own corner radius rounds every point. The points stay where they are in edit mode.
- **A boolean group's look follows its operation**: union, intersect and exclude take the top layer's fills, strokes and effects, subtract the bottom layer's (it was always the bottom one).
- **Alt draws a line or an arrow from its centre**, like the other shapes (it was ignored).
- **Stars keep to 3–60 points** (they went to 120; polygons keep 120, the documentation is silent); a junk `pointCount` is refused instead of becoming 5.
- **Delete and heal recomputes the curve**: the healed segment keeps its neighbours' tangents and passes through where the deleted point was (it reused the neighbours' handles, so healing over a circle cut deep inside it). Corners between straight segments heal straight, as before.
- **Shift-click on a selected point at a corner of the points' transform box takes it out of the selection** (it started a scale); a Shift-drag there still scales in proportion.
- **Outline stroke** turns the stroke's colour style into the outline's fill style, and the outline keeps the layer's opacity, blend, effects, constraints and visibility (they were lost).
- **The stroke panel's Miter angle shows degrees** (it showed the ratio 4 under that name; the default is ~28.96°); `node.set {miterAngle}` sets it and `get_node` reports a non-default join or angle.
- **Individual corners only for rectangles and frames**: polygons, stars and vectors have one radius (the toggle showed for them and set corners that weren't drawn).
- **Option/Alt+Shift+F flattens** (Cmd/Ctrl+E still does).
- **MCP `key` in vector edit mode reaches the edit tools first**, as the canvas does: tool letters, arrows, Delete / Shift+Delete, Cmd/Ctrl+J, Enter (Delete removed the whole layer; `X` was unknown).
**Missing documented behaviour, added**
- **Corner radius and star ratio handles on the canvas**: a handle inside each corner of a selected rectangle or frame, one inside a polygon's or star's top point, a ratio handle on a star's first inner point (`shape_handles.rs`). Dragging along a corner's bisector sets the radius of every corner (Alt: only that corner of a rectangle or frame, documentation silent), stopping where the corners meet; the ratio handle sets the inner radius. A readout shows the value while dragging; the handles hide under 48 px on screen, on locked layers, with several layers selected and in edit mode. One undo step per drag; `inspect_ui` lists them under `tool.shapeHandles`.
- **Count and Ratio fields** in the Design panel for polygons and stars (there was no way to change them in the UI).
- **Cut tool drags**: dragging across paths cuts them where the line crosses; parts that come apart move to layers of their own, each keeping its piece of the fill (`vector.edit.cut {from, to}`). A click still splits at a point or segment.
- **Paint bucket drags**: a drag fills or unfills every area it crosses the way the first one went (`vector.edit.paint {points}`), one undo step.
New strings go through `tr(...)` (the new fields reuse the existing Count / Ratio / Radius / Star / Polygon entries in `en.toml` and `es.toml`); the new fields have accessible names (an icon lead with its label). Each gesture and edit stays one undo step.
- Edit-mode toolbar (Move V, Pen P, Bend hold Cmd, Paint bucket Shift+B, Lasso Q, Cut X, Done)
replaces the tools while a vector is edited.
- Pen in edit mode continues open ends, branches from any point (vector networks), adds points on
segments and closes paths into fill regions; dragging pulls out mirrored handles.
- Paint bucket fills or unfills any closed area: faces of the network (half-edge walk, nested
pieces become holes), with a hatched preview of the area under the pointer.
- Bend tool / Cmd: bend segments, pull handles out of a point, click a smooth point to sharpen it.
- Lasso and marquee point selection, segment selection (shift adds), cut at a segment or a point.
- Per-point handle mirroring (none / angle / angle and length, inferred for existing files),
Alt-drag breaks it; smooth/sharp points; join and merge selected points (Cmd+J, Shift+Cmd+J).
- Delete opens the path, Shift+Delete heals it; arrows nudge points; Cmd+A selects all points.
- Design panel shows the selected points' position, corner radius and mirroring.
- Every gesture is one undo step; edit mode ends when its layer is undone away.
- Paths that end on their start without a ClosePath (ellipse outlines) stay closed and filled.
- New commands (vector.edit.tool/pen/paint/cut/lasso/mirroring/smooth/position/nudge/connect/...)
for the CLI, control channel and MCP; docs updated.
- Clippy: simplify a few boolean expressions flagged by the current toolchain.
