object.transformEach refused reflectX, reflectY, random and copy given
as text, but read strokes, corners, objects and patterns given as text
as the key left out. With Scale Strokes & Effects on,
{"scaleH": 200, "scaleV": 200, "strokes": "false"} scaled the stroke,
recorded an undo step and kept the params for Transform Again, which
repeated the call. artboard.rearrange, artboard.move and
artboard.duplicate read their patterns option the same way, and
artboard.setProps reads its patterns, strokes and corners options the
same way.
These commands now refuse such a value with "`<key>` must be true or
false" before they change anything. So do the other options and
numbers of artboard.setProps and artboard.move, the art of Duplicate,
Copy and Cut Artboard, the shape commands and path.create, path.close,
path.setHandle, path.moveAnchors, the Pencil, Curvature, Reshape
Segment and Blob Brush options, text.create, text.createInPath,
text.setRangeStyle, text.editRange, text.getRange, text.touchType,
text.areaOptions, type.step, the font size steps,
type.opticalMarginAlignment, type.systemLayout, type.fractionalWidths,
type.ruby, the symbol and swatch commands, the Appearance panel's
commands, the gradient and freeform gradient commands, Shape Builder,
Live Paint, Image Trace, the opacity of object.setProps, the radius,
sides and relativeRadii of object.setLiveShape, the reference point of
object.setBounds and the artboard of Align, Distribute and Distribute
Spacing. They refuse a number given as text with "`<key>` must be a
number, not <value>", and a gradient stop's tint with "stop <n>:
`tint` must be a number". A null still reads as the key left out.

Pen Cmd-borrow keeps Direct Selection when Alt is held so guide copy and other Alt modifiers on the lent tool still work.

With the Anchor Point tool, a drag from an anchor pulls out smooth handles.
Shift held at the press now moves the anchor instead, its handles keeping
their offsets; Shift kept down during the drag keeps the move at 45° steps
(the constrain angle), released it frees it. A Shift-click that doesn't
move leaves the anchor as it was. A selected blend's spine points follow
the same rule (object.blend.spine.moveAnchor).
The move goes through a new engine command, path.moveAnchor
{id, subpath?, anchor, x, y}, since path.moveAnchors only acts on the
direct-selected anchors and the Anchor Point tool keeps no anchor selection.

path.curvatureEdit, path.removeAnchor, path.convertAnchor,
path.reshapeSegment, path.split, path.setHandle and path.insertAnchor
read subpath as an unsigned integer and fell back to 0 for any other
value. A subpath of 1.5, -1 or "1" edited subpath 0 and the command
reported success. path.split read anchor and segment with as_u64 too
and treated any other value as absent, so a bad anchor beside a good
segment split at the segment.
These commands now refuse a subpath that is not a whole number of 0 or
more with "missing integer `subpath`", the error path.curvatureEdit,
path.removeAnchor, path.convertAnchor and path.reshapeSegment already
give for a bad anchor or segment, and path.split refuses such an anchor
or segment too. Without a subpath, or with null, they edit subpath 0 as
before. The document and the undo history stay as they were after each
error. The params text of the six commands that listed subpath as
required now marks it optional.
Docs: docs/mcp.md, docs/target-app-parity.md.
path.freehand takes redraw: {id, within}: the stroke's ends are placed on the path, anchors added there, and the section between them replaced by the fitted stroke, the shorter way round a closed subpath; a stroke that doesn't end on the path still draws a new one. The Pencil and Paintbrush send it for a stroke that starts on a selected path's outline away from its ends, within Edit Selected Paths' distance.
PathData::bounds measured each segment by its start, end and extrema,
as kurbo's bounding_box does. For a curve with a handle at about 1e308
in size, or an infinite one, kurbo's extrema computation overflows and
drops the extreme. The box then held only the anchors. The canvas check
after an edit reads that box for the selected objects, so path.create
kept a curve with handles at 1e308.
The new segment_bounds measures a segment by its control points when
one of them has an x or y that is infinite or larger in size than
f64::MAX / 16, and by its extrema otherwise, bit for bit as before.
curve_bounds joins those boxes as kurbo does, and PathData::bounds uses
it, so such a curve's box holds the whole curve and the canvas check
refuses an edit that leaves one selected.
Docs: docs/mcp.md, docs/target-app-parity.md.
path.reshapeSegment refused only a delta that was not finite. It moves
a segment's two handles by the delta divided by 3t(1-t), which is
0.1425 at t 0.05 or 0.95, so a finite delta above about 2.5e307 wrote
infinite handles into the path. object.blend.spine.reshapeSegment
refuses a delta of 1e9 pt or longer.
path.reshapeSegment now refuses a delta of 1e9 pt or longer, with its
"invalid delta" error. Two other path commands took a point with no
bound. path.convertAnchor with x, y at 1e308 put the two handles 2e308
apart, so the path's control box was infinitely wide, and path.freehand
through such points with keepSelected off fitted a path whose bounds
reached infinity. Both now refuse a point whose x or y is 1e9 pt or
more in size, with "x and y must be finite", the error
object.blend.spine.moveAnchor gives for the same bound.
Docs: docs/mcp.md, docs/target-app-parity.md.
Shift pressed while dragging a segment had no effect on the curve:
Direct Selection's curved-segment and spine-segment drags, the Anchor
Point tool and the Pen with Alt sent the pointer offset alone, and the
segment bent freely. The reference app keeps the handles in the
perpendicular direction and of equal length while Shift is held.
path.reshapeSegment and object.blend.spine.reshapeSegment take
perpendicular (default false, which keeps today's behavior). With it,
both of the segment's handles stand at right angles to the line between
its anchors, on the same side and at the same length, and the point at
t lies as far from that line as the moved point does. A smooth anchor
at either end stays smooth, as it does in a drag without perpendicular,
and a segment whose anchors coincide bends as it does without
perpendicular. With Direct Selection, Shift pressed once a curved
segment's drag has started sends perpendicular; Shift held at the press
still toggles the path's selection, as before. Direct Selection's
spine-segment drag and the Anchor Point tool's segment drag send Shift
as perpendicular too, so the Pen with Alt does as well. A straight
segment dragged with Direct Selection already moves at 45° steps with
Shift.

A Blob Brush stroke merged with every touching closed path of its
color that had no stroke, and the blob it drew or merged into was
always left selected. The Blob Brush Tool Options had Size only.
The Blob Brush Tool Options now have Keep selected and Merge only
with selection, both off by default. A blob that a stroke draws or
merges into is no longer left selected unless Keep selected is on,
and the rest of the selection stays as it was. While Merge only with
selection is on, a stroke merges only with selected blobs, and with
nothing selected it draws a new blob. The options persist like the
tool's Size, and path.blob takes keepSelected and mergeOnlySelection,
both false by default. Keep selected stays on by default for the
Pencil and Paintbrush.

After Object › Path › Remove Anchor Points the anchor that follows each
removed one is selected: round the end of a closed subpath, or the one
before it at an open subpath's end. Running the command again goes on
along the path, without picking each anchor first. Several anchors,
subpaths and paths each get their own next anchor; a path that goes
leaves nothing selected; one undo step restores the anchors and the
selection.
The Delete key still selects the remainder whole so a second Delete
removes it, and the Delete Anchor Point tool still leaves the path
selected whole.

The Curvature tool built its curve as a uniform Catmull-Rom: both handles of a
smooth point a sixth of the chord between its neighbours, the ends of an open
path without handles. Uneven spacing overshot or looped, a J or U from three
points bent sharply at the middle with straight legs, and the end segments
looked flat.
- `curvature_spline` (draw2.rs) makes each stretch of three points follow the
circle through them: a smooth point's tangent is that circle's
(`smooth_handles`), each handle `chord / (3 cos²(α/2))` long, α between
handle and chord capped at 90° (`arc_handle`). The ends of an open path
mirror their neighbour's tangent in their chord (`end_handle`). A turn
tighter than 30° (`TIGHT_TURN`) shortens its handles, so a narrow V comes to
a point. Degenerate points become corners. `path.curvature` and the rubber
band use it.
- `catmull_rom` is unchanged for the Pencil and Paintbrush fitting.
- `bend_last` (from: smooth), `curvature_move` on a smooth point, the point
`curvature_insert` adds on a straight segment, and `path.convertAnchor` to
smooth without x/y (`curvature_smooth`) use the same rule.
- `curvature_extend` gives the new end its end handle unless Alt-clicked
(`corner` param on `path.curvatureEdit`).
- Neighbours of a point dragged on an existing path keep their tangents (a
Pen-drawn shape isn't reshaped); the path being drawn re-curves throughout.
The Pen's pointer showed the new-path asterisk before the first anchor
and also while a path was being drawn, where a click adds the path's
next anchor. A new Cursor::PenDrawing, the pen nib without a badge, now
shows there. The close, convert and join badges still show over the
first anchor, the last anchor and another open path's end. The asterisk
shows only where a click starts a new path.
The Continue, Add and Delete badges now also show after another path
was selected while the Pen was still drawing (for example with a
Cmd-click). A click there already continued the path or added or
deleted an anchor, but the pointer showed the asterisk.
A Pencil or Paintbrush stroke always left the path it drew or continued
selected. The reference app's Pencil and Paintbrush options have Keep
selected for this, and VectorCraft's Tool Options had no such row.
The Pencil and Paintbrush Tool Options now have a Keep selected
checkbox, on by default, which keeps today's behavior. When it is off,
a new path is not selected and the selection stays as it was, and a
continued path is removed from the selection while the rest stays. The
stroke is still one undo step. The option persists like the tools'
other options, and path.freehand and brush.freehand take keepSelected.
Docs: docs/target-app-parity.md, docs/ui-parity.md, docs/control-protocol.md.
The Pencil gave every path a black stroke when the stroke was None. With Fill
new pencil strokes on and a fill set, the path now keeps no stroke; only a path
that would show nothing (no fill, no stroke) still gets black.
A drag near an anchor refitted the whole segments on either side of it, so a
short drag over a small bump on a long side turned the side into a curve from
end to end. The segments leading into the anchors under the drag are now split
where they enter the tool's reach, and only what is in reach is refitted.
Fixes#1273. A selected group or compound path shows its paths' anchors
with the Pen, but Pen + Alt only looked at paths selected directly, so an
Alt-click there started a new path instead of converting the anchor.

The endpoints of a selected segment are hollow, so select.anchors and select.anchorsMany now
start from no anchors of that path instead of toggling the endpoint off.
Cursor::precise listed every Pen state but PenJoin (added later, #794), so with Use Precise
Cursors on the Pen still showed its join badge over another open path's end.
PenJoin is a crosshair too under the preference.
The Pen join test now also checks the pointer over the other path's end is the crosshair with
the preference on (and PenJoin with it off, as before).

The Curvature tool only edited the path it was drawing. It now edits any
selected path, whatever drew it, keeping its shape except where edited:
a click on a point makes it the current (direct-selected) point and a
drag moves it, re-curving only its two segments (the neighbours keep
their handle directions); Alt-click or double-click toggles it smooth or
corner and Delete removes it; a click on a segment adds a smooth point
without changing the shape, and a drag moves it in the same undo step.
With an end of an open path current, clicks go on from it (the old
segments keep their shape) and a click on the other end closes it.
The edits go through a new path.curvatureEdit command (move, insert,
extend, close), path.convertAnchor and path.removeAnchor, one undo step
each. The tool now claims Delete/Backspace while it has a point to
remove, so the key no longer deletes the whole path.

As in Illustrator, the Pen shows its continue cursor over an end of any
open path, selected or not, and a click there selects the path and draws
on from that end (reversing it from its first end). While drawing, it
shows a join cursor over an end of another open path, and a click joins
the two into one path, in one undo step, which finishes the path.
path.join takes {ids: [a, b], ends: ["first"|"last", "first"|"last"]}
to join the ends asked for (the Pen's join); without them it joins the
selected paths' nearest ends as before. Joining a path with itself, or
anything that isn't a path, is an error.

Reported: Alt-click with the Pen should toggle an anchor between corner and smooth, and the
Control bar had no way to make a corner anchor smooth.
v0.5.0 already has Pen + Alt as the Anchor Point tool (#473) and the Control bar's and the
Properties panel's Convert buttons for direct-selected anchors, the path being drawn included (its
last anchor is selected). The remaining gap: with Direct Selection, the Pen, the Curvature or the
anchor tools, a path selected as a whole shows all its anchors selected, yet the Convert buttons
only appeared once anchors were direct-selected.
- chrome::anchor_controls decides what the Control bar and the Properties panel show: Convert and
Anchors for direct-selected anchors (as before), Convert alone for paths selected as a whole
with a tool that edits anchors (path.convertAnchors already converts every anchor of those);
Remove and Cut still wait for anchors direct-selected, as they act on those only.
- Tests: the Control bar and the Properties panel offer Convert for a whole rectangle with Direct
Selection and the Pen, not with the Selection tool, and smooth converts every corner; Pen + Alt
on the path being drawn makes a smooth anchor a corner (click) and a corner smooth (drag), and
drawing goes on. ROADMAP.

Reported: closing a shape by pressing on the first anchor and dragging out a curve flickered, and
releasing at the wrong moment left the shape open.
The press decided to close (path.close preview), but every move asked again which path was being
drawn: the closing preview leaves the path closed, so no longer one the Pen extends, and the move
fell through to "first anchor of a new path" (a path.create preview), the next move back to a
close of a path that no longer existed in the preview... The release committed whichever was last.
- The press now records what it placed (Place: the anchor, the path it goes on, none for a new
path, and whether it closes it), and the drag only shapes that anchor's handles: a close stays a
close, symmetric by default and Alt breaking the handles, and the release closes the path wherever
it ends. The first anchor of a new path no longer depends on the selection either.
- Tests: tools (the drag sees the closed path), engine (closed throughout a 12-move drag, symmetric
handles at the release), MCP headless pointer_gesture. ROADMAP.

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,

Discord feedback: Alt with the Pen didn't move a direction handle on its own, and there was no
way to break a path at an anchor and pull the ends apart.
- Pen: Alt held over a handle end or an anchor of a selected path (the one being drawn too) hands
the gesture to the Anchor Point tool, with the convert cursor: dragging a handle moves it alone,
clicking a smooth anchor makes it a corner, dragging an anchor pulls out symmetric handles.
Drawing goes on afterwards. Handles hidden by a partial anchor selection aren't grabbed.
- path.cutAtAnchors cuts at the direct-selected anchors in one undo step: a closed path opens
there, an open one becomes one path per piece, and one anchor of each cut stays selected so a
drag pulls the path apart. It answers {ids} and refuses (no undo step) when only open ends are
selected. path.convertAnchors checks `to`, skips stale anchor refs instead of indexing past
them, and keeps a smooth anchor's handles when converting to smooth.
- SubPath::cut_at and SubPath::smooth_anchor (geom) now back path.split, path.cutAtAnchors,
path.convertAnchor and path.convertAnchors, replacing three copies of that logic.
- Control bar and Properties panel: "Convert:" corner/smooth and "Anchors:" remove, connect
(Join), cut buttons when anchors are selected; Cut Path on the task bar and the context menu.
New original icon dc-anchor-smooth.svg (ASSETS.md row).

- Parity: Object › Path › Remove Anchor Points now runs the new command (`path.removeAnchors`,
the menu's feature name) instead of `path.deleteAnchors`, which deleted the anchors with their
segments and opened closed paths; that stays the Delete key's command ("Delete Anchor Points",
off the menu). No second "Smart" item.
- Geometry: the refit moves to `vectorcraft_pathops::remove_anchor` on the existing least-squares
fitter (fixed end tangents, a golden-section search for where the curve passes the removed
point) instead of a ~1,000-candidate grid search in geom (about 4 ms per anchor, now well under
0.1 ms). Two straight sides stay one straight side (a rectangle loses a corner and becomes a
triangle), as Illustrator does; non-finite input leaves the handles alone.
- The Delete Anchor Point tool (`path.removeAnchor`) uses the same function, replacing its
heuristic handle stretch; the explicit id/anchor and `fit` params of the new command are dropped
as duplicates of it. The command is enabled by direct-selected anchors (`has_anchors`), not a
UI override.
- The Control bar shows an icon button (the Delete Anchor Point icon, tooltip "Remove Anchor
Points") instead of a 204 pt text button; the labels reuse the translated "Remove Anchor
Points"; zh-hant gains "Delete Anchor Points". The Pen test that pinned Alt-click as plain Pen
(Illustrator's Alt over an anchor is Convert Anchor Point) is dropped.
- Tests for the refit, closed paths, straight sides and bad input; docs/mcp.md and ROADMAP.

path.smartRemoveAnchor stays. Object › Path, the Control bar, the contextual task bar, Properties, and the canvas context menu run it on direct-selected anchors. The Pen no longer uses Alt/Option for this, so that key stays free for Convert Anchor Point.
- A dragged handle no longer snaps to its own path's bounds and centre, which move with the
handle; the path's anchors are point and alignment targets instead.
- Shift steps 45° from the Constrain Angle preference, like the cut and gradient tools.
- snap_draw and snap_handle share one pixel/grid/smart-guides switch.
- A test that a smooth anchor's opposite handle turns with a Shift-dragged handle and that Alt
still breaks it, and the tools' module docs (both from #338).

Dragging a direction handle with Direct Selection or the Anchor Point tool
sent the pointer position straight to path.setHandle: Shift did nothing and
the handle never snapped, while the Pen already constrains the handles it
pulls out.
guides::snap_handle places a dragged handle: with Shift at a multiple of
45° from its anchor (the Pen's constraint, keeping the dragged length),
otherwise snapped as a drawn point is (smart guides, the grid, pixels).
Both tools use it and show the smart guides while the handle moves.
