Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

History was limited by step count only; a whole-selection move of 50k paths keeps ~40 MB per
step. Steps now carry a size estimate (only unshared subtrees are visited) and the oldest are
dropped beyond a byte budget, keeping the last 8. Documents entering history drop their id
index, selections are shared between steps, the command journal is bounded (held while an
Action records), and document resources are copy-on-write. Saved files are byte-identical.

These commands edited the document even when nothing changed, so the
call recorded an undo step, emptied Redo and marked the document
modified:
- All Artwork Above and Other Layers (Object › Lock and
Object › Hide) with nothing to lock or hide: no object above the
selection, no other layer, or every one already locked (Lock) or
hidden (Hide).
- Transform Each with no object to transform, and without Copy when
both scales are 100% and there is no move, rotation or reflection.
- Rearrange All Artboards when no artboard moves, or with no artboard.
- stroke.widthPoint.set and stroke.widthPoint.copy when the profile
comes out as it was, and stroke.widthProfile.set with the profile the
strokes have already.
- Liquify when the stroke reshapes no path, and Puppet Warp given the
pins the art holds already (rest: true), or without rest when every
pin stays where it is and turns the art by 0° or is free.
- Define Perspective Grid with the grid the document has, Attach to
Active Plane with no object, Release with Perspective on art that is
not in perspective, Move Plane to where the plane is, without copies,
and Move Plane to Match Object when the plane is there and active
already.
- Move, Nudge and Transform in Perspective without Copy when no object
moves (1e-9 pt or less along the plane or its normal, Snap to Grid
included, or the identity), and Transform Again after one.
These commands now return without editing the document. The replies
have the same form as before. Transform Each with Copy and no object
to transform no longer empties the selection. Puppet Warp without rest,
with every pin where it is and turning the art by 0° or free, no longer
turns a live shape into a plain path. All Artwork Above still deselects
selected objects that are hidden or locked. Width Point counts a change
of 1e-9 or less in a point's place or width factor (its width over half
the stroke weight) as none. OK in Width Point Edit with the widths it
shows, with or without Adjust Adjoining Width Points, records no undo
step. After a move in perspective that moved nothing, Transform Again
repeats the identity.
One line in the evidence list of docs/target-app-parity.md names the
commands.
stroke.widthPoint.set and .copy read `index` with `as_u64() as usize`:
a malformed index ("bad", -1, 1.5) was taken as no index, so set added a
new point instead of failing, and a huge one wrapped round on wasm32.
They now read it through point_indices, as remove does since #1079:
anything but an index of an existing point is "no such width point".
A null index is still no index (set adds a point).

point_indices moves from freeform.rs to the cmd param helpers so
stroke.widthPoint.remove parses `index` and `indices` with it, and a
malformed entry reports the translated "no such width point".

Type and symbol instances attached to a plane keep their art and carry a projection
(Node.perspective.projection, append-only); the canvas and every export draw their outlines
through it (reshape/bake), so they are foreshortened and stay type and symbol instances. Bounds,
hit testing and transforms follow the projection. Object › Perspective › Edit Text
(perspective.editText, or double-clicking with the Perspective Selection tool) shows the type flat
where it is drawn in isolation mode; exiting isolation projects it again. Release with
Perspective keeps their look. Copies, pastes, duplicates and Selection-tool moves keep the
attachment (the art moves as dragged). Flare, spiral and polar grid draw on the active plane, and
so do the click-to-size shape dialogs (perspective.draw `at`: sizes in plane units).

- A compound path's stroke lives on the compound: the tool edits it through
any member, and stroke.widthPoint.* / stroke.widthProfile.set given a member
edit the compound's profile.
- Width points show on every subpath the stroke runs along (not just the
first) for the hovered and the selected stroke.
- Cursors: the Width tool's own glyphs off a stroke, over a stroke (a drag
adds a point) and over a width point or handle (a drag moves or widens it).
- Hint-bar text for the tool.

Holding the brush still keeps Twirl, Pucker and Bloat applying, scaled by the
time held: a new Tool::tick (time supplied by the host: canvas frames, or
`holdMs` on ui.pointer / pointer_gesture events) repeats the last point every
0.1 s, one more dab there. Liquify never touches graphs, meshes, type, symbols,
images, or envelopes, repeats and blends with their contents, nor guides in
selection mode; those under the brush come back in `skipped` with a `warning`
that the status bar shows (UiRequest::Status). A drag applies only the dabs
each new sample adds (the stroke's state is kept between previews), giving the
same result as the whole stroke, so journal replay still reproduces it.

View > Perspective Grid gains Show/Hide Rulers, Snap to Grid (on by default),
Lock/Unlock Grid and Lock Station Point, with flipping labels and checkmarks (and
Show/Hide Grid's label). Lock Grid stops the grid widgets from dragging; Lock
Station Point swings the other vanishing point around the station point; Snap to
Grid lands drawn corners and moved edges on gridlines within a quarter cell
(perspective.draw/move take snap?); Show Rulers draws a ruler up the true height
line in the grid's units. Gridlines draw in the Define Grid colours and opacity.
New commands perspective.grid.lock/lockStation/snap/rulers (view state).
Existing tests that measure exact perspective moves (two in tests_distort.rs,
the persp_session helper of tests_persp_select.rs) turn snapping off first (it is on by
default and would move their exact corners onto gridlines).

The grid keeps per-plane offsets (leftOffset, rightOffset, groundOffset). Each plane has a widget
(a diamond in its colour) that the Perspective Grid and Perspective Selection tools drag: plain
moves the plane, Shift moves the objects on it too, Alt copies them (perspective.plane.move).
Double-clicking a widget, or ui.perspectivePlane, opens the plane's options dialog (location; Do
Not Move / Move All Objects / Copy All Objects). Object › Perspective › Move Plane to Match Object
(perspective.plane.matchObject). New objects attach where the plane is. Grid edits leave
attached art in place as the reference app does; perspective.grid.set {reproject: true} moves it
with the grid.

- Pins show as soon as the tool has art selected: automatic ones at the
centre and the middle of each limb's end (at least three), until pins are
placed. They stay across tool switches while the selection is unchanged and
a new selection starts afresh.
- The pins live in the document (Document.puppet, never saved) with the rest
shape they started from: every warp starts from it, so warps don't stack and
dragging a pin back restores the original; Undo/Redo take the pins back with
the art. Adding and deleting pins are undo steps too.
- object.puppetWarp gains rest: true (the tool's pins); the new query
object.puppetWarp.pins reads them. A click off the mesh adds nothing and
says so (not-allowed cursor, canvas label); the command refuses such pins.
- The mesh grid covers the expanded art, so tiny art with a wide Expand no
longer allocates millions of cells.
- Tests on groups, compound paths and open strokes.

The Perspective Selection tool shows the selection's bounding box in perspective; its handles
scale in plane space (perspective.transform; Shift proportional, Alt from the centre). Alt-drag
moves copies that stay attached, pressing 5 while dragging moves along the plane's normal
(ToolKey::Digit, delivered by the canvas and MCP press_key), and the arrow keys nudge in
perspective (perspective.nudge). Transform Again repeats the last perspective move or scale in
plane space. Attachments (plane and depth) now live on the objects (Node.perspective), so copies,
duplicates and pastes keep them; grids from older files hand theirs over. Homography moves to
vectorcraft-geom. Hint-bar text for the tool.

View > Perspective Grid > One/Two/Three Point Perspective list the built-in views
([1P/2P/3P-Normal View], plus Low and High views generated in code) and the saved
presets of each type; Save Grid as Preset... and Define Grid's Preset menu and Save
Preset... save the fields. Edit > Perspective Grid Presets... (previously a
mislabelled reset to the two-point grid) manages them: New, Edit, Delete, Import,
Export (.vcperspective), stored with the preferences. New commands
perspective.presets.list/save/delete/export/import; perspective.grid.preset takes
a preset name. Preset import is fuzzed.

Double-clicking a Liquify tool opens its Tool Options (dialog liquifyOptions):
the shared Global Brush Dimensions (Width, Height, Angle, Intensity, Use
Pressure Pen), the tool's options (Detail, Simplify with its checkbox, Twirl
Rate, Complexity, Brush Affects, Horizontal/Vertical) and Show Brush Size.
The canvas captures pen pressure from pen/touch force, ui.pointer and MCP
pointer events take `pressure`, and object.liquify takes [x, y, pressure].
Fixes: LiquifyParams::to_json now sends affectAnchors/In/Out; Alt-drag sizes
the brush from its current size (Shift keeps proportions) instead of
collapsing it. Hint-bar text for the seven tools. Registers the MCP Liquify
tests file added in M8.2.

- Alt-dragging near (not on) a selected pin turns the art around it; the pin
keeps that turn through later warps. arap::Pin gains an angle constraint and
object.puppetWarp takes angles: [deg|null...].
- Shift-click adds pins to the selection or takes them out; dragging a pin
moves every selected pin. Select All Pins selects them all (it used to
deselect). Alt-click no longer deletes a pin; Delete removes the selection.
- Control bar: Expand (0 allowed), Show Mesh (on by default), Select All
Pins. Hint-bar text for the tool.

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.

Double-clicking a width point opens Width Point Edit (Side 1, Side 2, Total Width, a link
keeping the sides equal, Adjust Adjoining Width Points, Delete; dialog `widthPoint`, also
`ui.widthPointEdit`). Shift-click selects several width points, which drag and widen together
as one undo step; Alt-dragging a point's centre copies it (`stroke.widthPoint.copy`); dropping a
point onto another makes a discontinuous point (two points at the same t), and the stroke's
width steps there. `stroke.widthPoint.set` takes `adjustAdjoining`, keeps a discontinuous point
when only its widths change, and `stroke.widthPoint.remove` takes `indices`. Flipping a profile
along the path swaps the sides of its steps; `document.inspect` reports `widthPoints`.
