CodeRabbit follow-up for #4293. Add 2026-10-26 revision-history rows and
status-line updates for EPS Save and Save As in file-format-parity, gaps
(G9), roadmap and target-app-parity; move the completed EPS Save note in
roadmap's M4 row out of "Left:". Save-back is recorded as done; G9 import
fidelity and Illustrator editing-data writing (#868) are unchanged. Scores
and estimates unchanged. Docs only.
File > Document Color Mode and document.open {colorMode} converted the
colors of the layers, symbols, pattern tiles and swatches only. Graph
designs, graphic styles, the art of opacity masks, the tile that
pattern editing's Cancel puts back and the art of brushes kept their
old color model (only a tint of a global swatch in a graphic style or
a mask followed the swatch), so a CMYK document could still apply,
place or print RGB colors from them.
These now convert with the rest, in the same undo step: their solid
colors, gradient stops, text runs and mesh points, nested masks
included. A Hue Shift brush's key color takes the converted color of
the art color it matches, a tint of a global swatch included. The
brush library is stored again only when one of its colors changed. A
tint of a global swatch in any of these places becomes the converted
swatch's color at its tint, as in the layers. The reply's changed
count covers the colors of the layers, symbols, graph designs, pattern
tiles and opacity masks; the colors of graphic styles and brushes
convert without being counted.

While an opacity mask or a pattern was edited, a Shaper double-click
selected a Shaper Group's original shape without isolating the group's
original shapes. A Selection tool press on that shape then selected and
moved the whole Shaper Group over the art the group shows, and started
a marquee over a part of the shape the group does not show.
A press on the selected original shape now holds it for a move, and
the pointer shows the move cursor over it.
While an opacity mask or a pattern was edited, a Shaper scribble and
Object › Shaper › Release and Expand ended isolation, and a Shaper
double-click on a Shaper Group isolated the group's original shapes.
Each replaced the editing layer's isolation while the document stayed
in mask or pattern editing. A click on the Shaper Group's mode widget
did the same through object.isolate.
A scribble, Release and Expand now keep the editing layer isolated in
these modes, and end isolation as before outside them. A double-click
with Shaper selects the original shape under the pointer without
isolating the group's original shapes, and the mode widget does not
show while a mask or a pattern is edited.
Docs: docs/shaper.md, docs/target-app-parity.md.
object.isolate's errors "type objects can't be isolated", "the object
is hidden or locked" and "missing id" had no row in any catalog, so the
status bar showed them in English in every language. The same was true
of layer.target's "the object is outside the isolated group", the other
isolation-mode error in the commands.
Each of the four messages now has an @msg row in every catalog that
translates all status and error messages and in Bulgarian, Danish,
Indonesian and Dutch. layer.target also gives "the object is hidden or
locked", and several other commands that take an id also give "missing
id", so the same rows translate those errors.
Docs: docs/target-app-parity.md.
The Live Paint Selection tool acted only on the press, so a drag
selected at most the one face or edge under the pointer. The reference
app selects every face and edge a marquee touches, partly enclosed ones
included, and a Shift-drag adds them to the selection or removes them.
A drag of 3 pixels or more now draws a marquee. On release, select.set
selects the faces and edges it touches, or select.none runs when it
touches none. With Shift held at the press, select.toggle runs with
what it touches, and nothing runs when it touches none. A face that holds the whole marquee counts. Select Fills off
leaves faces out, and Select Strokes off leaves edges out.
A click now changes the selection on release instead of on the press,
so Escape between the press and the release, which also removes the
marquee, leaves the selection as it was. The tool no longer highlights
or selects the faces and edges of a Live Paint group that is locked, on
a locked layer or on a locked artboard, or that is outside the isolated
art in isolation mode.

Pattern Brush Options has a menu below the Outer Corner Tile and the Inner
Corner Tile. Each can be the brush's own corner art (Original), None, or one
of four tiles made from the side tile at each corner of the path:
- Auto-Centered stretches one side tile around the corner, centered on it.
- Auto-Between bends a side tile on each side into the corner, the two
meeting on the corner's diagonal.
- Auto-Sliced lays a side tile on each side past the corner and masks it
at the diagonal, so the two meet like a mitered frame.
- Auto-Overlap lays a side tile on each side past the corner, overlapping.
The tiles are straight at the corner and follow the path towards the side
tiles, so they meet a curve that runs into the corner. A side tile taller
than the corner can reach is stretched along until the two sides meet. On a
short path, a corner's tile is squeezed along so that it covers at most the
path up to an open path's end and half way to the next corner, and its two sides still meet on the
corner's diagonal.
The definition stores the choice as `outer_source` and `inner_source`
(`none`, `autoCentered`, `autoBetween`, `autoSliced`, `autoOverlap`), which
`brush.options` sets. Corner art wins over a source. A brush saved without
a source draws as before: a kind of corner without art takes the other
kind's art. None leaves that kind of corner empty.
Docs: docs/mcp.md, docs/target-app-parity.md.
After a click picked the first object with the Blend tool, Escape did
nothing: the pick stayed, and the next click on another object blended
the two. After a blend was made, Escape did not stop the next click
adding to it either.
Escape now drops the object picked first and stops the next click
adding to the blend just made, as a click on empty canvas does, so the
next click picks a new first object. The document and the selection
stay as they are, and no undo step is added.

Enter Isolation Mode worked while an opacity mask was edited, and Edit
Opacity Mask and View Opacity Mask worked in isolation mode, so each
mode replaced the other's isolated art. In the reference app, isolation
mode can't be entered while a mask is edited, and mask editing can't be
entered in isolation mode.
object.isolate and perspective.editText, which shows type in isolation
mode, are now off while an opacity mask is edited, and a call returns
an error that ends "stop editing the opacity mask first". In isolation
mode transparency.editOpacityMask and transparency.viewOpacityMask are
off, and transparency.makeOpacityMask refuses one target, an object or
a layer, which it would take into mask editing; a call returns an error
that ends "exit isolation mode first". Make Opacity Mask with two
objects still masks one with the other. Pattern editing mode does not
count as isolation mode for these commands.
Object > Perspective > Edit Text, the canvas context menu and the
Transparency panel's menu and Make Mask button follow the commands'
enablement. A click or Alt-click on the mask thumbnail in isolation
mode shows the error and does not edit the mask. While a mask is
edited, the Contextual Task Bar leaves out Isolate, and the Properties
panel's Quick Actions leave out Isolate Group.
Docs: docs/mcp.md, docs/target-app-parity.md.
The chips drew the first selected object's fill and stroke. They now show
the paints the Fill and Stroke proxies show, a group's painted art
included, and a "?" when the selected objects' paints differ. A click on
either chip shows the Swatches panel through `window.panel.activate`, so
it also appears when the panel is floating, closed or in an expanded dock
column; an open flyout stays open. The progress doc describes the
reference app's bar in its own words.
The task bar's Fill chip had no Stroke counterpart. A Stroke chip now sits
beside it, drawn as a ring with the selected object's stroke paint, as the
Control bar's Stroke chip is. A click on it brings the Stroke proxy forward
and opens the Swatches panel, as a click on the Fill chip does for the
Fill proxy. The chip is left out with the Artboard tool, as Fill is.
The bar's width estimate, which centers the bar under the selection, grows
by the chip's width. The drag test's first square moves 20 pt right so its
bar still starts inside the canvas.
Escape during a Selection tool move or Alt-drag copy, a bounding-box
scale or rotation, a marquee, or a drag of a corner widget, a pie widget
or the brackets of type on a path did nothing, and the release then
applied the drag. Only a ruler guide, mirror axis or grid repeat drag
and the loaded text took Escape.
Escape in any of these drags now cancels it, the way Direct Selection
cancels its drags: the art returns to its state at the press, an
Alt-drag leaves no copy, no undo step is added, and the release does
nothing.
Outside a drag Escape works as before.
Docs: docs/mcp.md, docs/target-app-parity.md.
With View › Snap to Glyph and Smart Guides on, a point drawn near a single
line of live type now also lands on the anchor points of its glyphs and lines
up with its x-height (raised or lowered by Baseline Shift) and with the edges
of each character's advance width along the baseline (proximity guides). In
rotated type the baseline, x-height and proximity guides run at the type's
angle, and type of one glyph also has angular guides along the glyph's slanted
straight segments; a segment that Shift keeps to its angle slides onto them.
A paragraph shows glyph bounds only, so its baselines are no longer guides.
FontFace::x_height gives a face's x-height in font units.
Envelope Options stored Anti-Alias and Preserve Shape Using, but nothing that
draws an image read them: a distorted image was always smoothed and always
cut into clip groups.
- With Anti-Alias off, each piece of a distorted image is marked pixelated
(saved as `pixelated`). The renderer draws it with nearest-neighbor
sampling and without mips, SVG export writes `image-rendering: pixelated`,
and PDF export writes it without /Interpolate.
- With Preserve Shape Using Transparency, each piece is the image with a
white opacity mask in the piece's shape instead of a clip group. The
renderer paints an image whose mask is one plain white path straight into
that path, as it does for an image in a clip group, when the path lies
inside the image's frame.
Docs: docs/mcp.md, docs/target-app-parity.md.
The reference app keeps the inner radius of a star constant when Ctrl
or Command is held after the drag starts. VectorCraft's Star tool took
the held radius from the first drag event that carried the key, using
that event's outer radius. The canvas sends a drag only once the
pointer moves, so a key pressed with the pointer still scaled the
inner radius with the next move before holding it.
Ctrl/Cmd now holds the inner radius the star showed at the last drag
position before the key went down, with Alt's straight shoulders when
Alt was held. A new press and Escape clear the held radius. Before,
after a drag canceled with Escape, the next star took the canceled
star's inner radius when Ctrl/Cmd went down before that star's first
drag event.
Docs: docs/target-app-parity.md.
Escape did not cancel a drag with the Anchor Point, Mesh, Shape Builder
and Measure tools, or a Direct Selection drag of a mesh point, a corner
widget or the brackets of type on a path: the drag went on until the
mouse was released. Escape cancels every other Direct Selection drag
and a drag with the Free Transform, Rotate, Reflect, Scale, Shear and
Gradient tools.
Escape now cancels an Anchor Point drag, a Mesh tool drag of a mesh
point or handle, and a Direct Selection drag of a mesh point or handle,
a corner widget or the brackets of type on a path. The art goes back to
how the press found it, no undo step is added, and the rest of the drag
and the release send nothing. Escape during a Shape Builder drag ends
it, so the release merges and deletes nothing; the tool takes Escape
only during the drag. Escape during a Measure tool drag ends it and
brings back the measurement shown before the press. Escape after an
Anchor Point or Direct Selection press that has not moved yet drops the
press. Otherwise, outside a drag, Escape does what it did before.
Docs: docs/mcp.md, docs/target-app-parity.md.
Edit › Keyboard Shortcuts listed every engine command with a menu path,
whatever its params. A shortcut runs a command with no params, so a key
given to File › Document Setup › Units ran document.setUnits with {}
and failed with "unknown units".
The dialog and shortcuts.list now leave out a command with a menu path
and no default shortcut when no item of the menu bar runs it without
params, it opens no dialog when run without them, and its params doc
names a required field. This leaves out 38 commands, among them the
Graphic Styles, Swatches and character and paragraph style commands
that take a name. A command whose shortcut the user has changed is
still listed, where the key can be changed or cleared, and a saved key
still runs and conflicts as before. Every command with a default
shortcut stays listed.
Docs: docs/mcp.md, docs/target-app-parity.md.
The reference app disables its Lock, Hide and Show All menus in
isolation mode. In VectorCraft every item of Object › Lock and
Object › Hide, Unlock All and Show All worked there.
In isolation mode, object.lock, object.lock.above,
object.lock.otherLayers, object.hide, object.hide.above,
object.hide.otherLayers, object.unlockAll and object.showAll are now
off. Their menu items are greyed out, and a call returns an error
that ends "exit isolation mode first". The Contextual Task Bar's
Lock button is greyed out too, and the Properties panel's Quick
Actions leave out Lock. Pattern editing mode and opacity mask editing do not count as
isolation mode for these commands. The check is outside_isolation in
cmd.rs, with has_selection_outside_isolation beside it.
Docs: docs/mcp.md, docs/target-app-parity.md.
Escape did not cancel a drag with the Puppet Warp, Perspective Grid,
Perspective Selection and Liquify tools: the drag went on until the
mouse was released. Escape cancels a drag with the Direct Selection,
Gradient and Artboard tools.
Escape now cancels a Puppet Warp pin drag or turn, a Perspective Grid
handle or plane widget drag, a Perspective Selection move, resize or
plane widget drag, and a Liquify stroke. The art and the grid go back
to how they were when the drag began, the undo history does not
change, and the rest of the drag and the release send nothing. Puppet
Warp selects again the pins that were selected before the press.
During a Liquify Alt-drag that sizes the brush, Escape puts the brush
size back; the tool claims Escape only then. Escape during a
Perspective Selection press that has not moved past the drag threshold
ends the press, so moving on does not start a move. Otherwise, outside
a drag, Escape does what it did before.
Docs: docs/mcp.md, docs/target-app-parity.md.
A closed arc from Arc Segment Tool Options, an Arc tool drag or
shape.arc with lengthX and lengthY closed through the box's bottom-left
corner with Base Along X, which makes a convex arc a quarter-ellipse
sector. With Base Along Y it closed through the corner a convex arc
bulges toward, so it drew the thin sliver between the arc and that
corner instead.
Such a closed arc now closes through the corner across from the one a
convex arc bulges toward with either base, so the Y-axis arc, open or
closed, convex or concave, is the X-axis arc mirrored top to bottom.
Open arcs and arcs with Base Along X are unchanged. The two-point
shape.arc form, whose params list no baseAlong, now closes through
(x1, y2) whatever baseAlong says.
Docs: docs/target-app-parity.md.
The Character Styles and Paragraph Styles panels took only clicks on
their rows. The reference app copies a style dragged onto Create New
Style and deletes a style dragged onto Delete.
A style row can now be dragged. Dropped on Create New Style, the style
is copied with charStyle.duplicate or paraStyle.duplicate, as the panel
menu's Duplicate does, and the panel highlights the copy. Dropped on
Delete, the style is deleted with charStyle.delete or paraStyle.delete,
as the Delete button deletes the highlighted style, and Delete accepts
a dragged style even when the highlighted one is Normal or none. Normal
is not deleted. Each button is outlined while a row it accepts is held
over it, and each drop is one undo step.
Docs: docs/target-app-parity.md.
A Blob Brush stroke used to merge with every closed path of its fill
color and no stroke that it touched, anywhere in the document, across
layers and groups and past objects of other kinds. It now merges with
the topmost such path it touches, and with the other touched matching
paths in the same group or layer that are next to that path in
stacking order, with no other kind of object between them. Merge only
with selection still limits the candidates to selected paths. The
merged path keeps the topmost path's id and place.
The reference app places a new layer below the selected layer with
Ctrl+Alt-click (Command+Option-click) on the New Layer button, and a
new sublayer at the bottom of the layer list with the same click on
the New Sublayer button. In VectorCraft that click opened Layer
Options, and New Layer and New Sublayer always added the layer above
the current layer and the sublayer on top of the layer's contents.
layer.new takes below, which adds the layer directly below the current
layer at its level, and layer.newSublayer takes bottom, which adds the
sublayer under the parent's contents. In a clipping layer the new
sublayer goes above the clipping path. Each is one undo step, and
below is refused together with top. A Cmd/Ctrl+Alt-click on the
Layers panel's New Layer and New Sublayer buttons runs them. A plain
click, an Alt-click and a Cmd/Ctrl-click work as before.
Docs: docs/mcp.md, docs/target-app-parity.md.
While the Type tool edits type, Edit > Undo and Redo (the menu, the
keyboard, the History panel and MCP all run edit.undo and edit.redo)
left the caret at its byte offset, clamped to the text. Typing "abc"
before "XYZ" and pressing Undo left the caret after "XYZ".
The engine now tells the active tool about edit.undo and edit.redo
before it finishes the command. The Type tool keeps the edited text and
a list of the steps that changed it, and puts the caret, with nothing
selected, at the end of the span the step changed: where typed text
began after its Undo, after restored text after the Undo of a deletion,
and after retyped text after Redo. For the steps the tool made, it keeps
where the span ended, so text that repeats the characters next to it
puts the caret at the right end. A step that changes no characters,
such as a formatting change, leaves the caret and the selection as they
are. Typed lists keep their caret positions.
GIF, WebP and Targa files hold no resolution field, so document.formats and
the export docs now say that ppi, and the resolution that width or height
gives, are stored in the file except in those three formats.
PNG, PNG-8, JPEG, WebP, GIF, TIFF, BMP, Targa and PSD exports take
`width` or `height` in pixels. Each file is scaled so that its own
artboard, `rect` or art bounds is that wide or high, so with
`useArtboards` every file gets its own scale. `width` wins over
`height`, and either wins over `ppi` and `scale`, in the order an
Export for Screens row reads its size. The scale stays within 0.01 to
64 pixels per point and the file stores the resolution that results.
A value that is not a positive number is refused.
The per-file scale comes from `ScreenSize::scale_for`, which Export for
Screens rows already use. Rows keep their own size: their format
settings still drop `width` and `height`. `document.formats` lists the
two options for every raster format.
With `zip: true`, document.exportForScreens deflated nothing: every file
went into the archive stored. Each file is now deflated, or stored when
deflating does not make it smaller, as file.package's archive does. The
file list, the names and the reply's fields stay the same; `bytes` and
the archive's contents change. Entries keep the fixed 1980-01-01 date, so
the same files still give the same archive.
The deflating writer moves from package.rs into fileio/zip.rs as
`zip::deflate`, beside `zip::store`, and file.package calls it there with
its own date and error text. The test reader `zip::entries` reads
deflated entries too. The `zip` option's text in docs/mcp.md,
docs/control-protocol.md and the command's params says the files are
deflated.
An Alt-click right of a short layer name, inside the wider rename
target, no longer replaces the selection. The isolated layer's own row
now selects the art inside it (layer.selectAll), where it cleared the
selection before. The doc line says the click selects visible, unlocked
art and clears the selection on a hidden or locked layer.
The reference app selects all objects on a layer with an Alt-click
(Option-click) on the layer's name in the Layers panel. In VectorCraft
an Alt-click on a name did what a plain click does: it highlighted the
row and made the layer current, and the art stayed unselected.
An Alt-click on the name of a layer or sublayer now also selects its
visible, unlocked art, as the row's selection square does
(layer.selectAll), and the layer still becomes current
(layer.setCurrent). On a locked or hidden layer the click clears the
selection, as that row's selection square does. On a group or object
row, beside the name, and with Shift or Ctrl/Cmd held as well, the
click does what it did before.
Docs: docs/mcp.md, docs/target-app-parity.md.
The reference app resets a gradient to black and white when the
gradient button in the Tools panel is Cmd/Ctrl-clicked, and to the
default black and white linear gradient when the Gradient Fill box in
the Gradient panel is Cmd/Ctrl-clicked. In VectorCraft a Cmd/Ctrl-click
on either did what a plain click does, and the reset was only in the
Gradient panel menu.
A Cmd/Ctrl-click on the Gradient panel's thumbnail or on the Tools
panel's Gradient button now makes the gradient of the active Fill or
Stroke a linear gradient with the White, Black stops, through
paint.editGradient, as one undo step. A solid or no paint becomes that
gradient, and with nothing selected the default paint changes. A plain
click keeps its behavior, and the panel menu's Reset to White, Black
is unchanged.
Docs: docs/target-app-parity.md.
The reference app selects the complement of the current fill or stroke
on a Cmd/Ctrl-click of the Color panel's color bar and the inverse on a
Cmd/Ctrl+Shift-click, and with Alt (Option) also held it changes the
nonactive one. In VectorCraft these clicks picked the spectrum's color,
and a Cmd/Ctrl+Shift-click cycled the color modes.
A Cmd/Ctrl-click on the spectrum now applies Complement and a
Cmd/Ctrl+Shift-click applies Invert to the active Fill or Stroke, as
the panel menu's items do: a selected gradient stop or freeform point
is recolored in place, and a solid color goes through paint.complement
or paint.invert. With Alt also held, the click runs the command on the
inactive proxy, which stays behind. A Cmd/Ctrl drag still picks colors,
and plain, Alt and Shift clicks keep their behavior. The panel menu's
Invert and Complement use the same code.
Docs: docs/target-app-parity.md.
A click with the Scissors tool cut the path whether or not Alt was
held, and the cursor stayed the Scissors cursor. The reference app's
shortcut list has "Switch Scissors tool to Add Anchor Point tool" on
Alt (Option).
While Alt is held, a click with the Scissors tool now does what a click
with the Add Anchor Point tool does: on a segment it adds an anchor
point with path.insertAnchor in one undo step, and the path is not cut.
The cursor is the Add Anchor Point tool's while Alt is held. When Alt
is let go, the cursor is the Scissors again and a click cuts.
Docs: docs/target-app-parity.md, crates/tools/src/cursors.toml.
The reference app's shortcut list switches between its Type tools with
Shift and with Alt (Option). VectorCraft's Type tools had no such switch.
While no type is being edited, a press with Shift held makes new type
with the chosen tool's horizontal or vertical counterpart: Type and
Vertical Type, Area Type and Vertical Area Type, Type on a Path and
Vertical Type on a Path. A press with Alt held makes it with Type on a
Path in place of Area Type, or the reverse, in the same writing
direction. With both keys held, both switch. The keys held when the
press starts are the ones that count. The pointer shows the tool the
press acts as, and the chosen tool stays selected. While type is being
edited, Shift and Alt work as they did.
Docs: docs/target-app-parity.md.
The reference app switches the units of measurement with
Ctrl+Alt+Shift+U on Windows and Option+Shift+Command+U on macOS.
VectorCraft could set the document's units with document.setUnits or
a right-click on a ruler, but no command stepped through them and no
key did it.
document.switchUnits (Switch Units, default Cmd+Alt+Shift+U) sets the
document's units to the next one in the order a right-click on a
ruler lists them: Points, Picas, Inches, Millimeters, Centimeters,
Pixels, Feet & Inches, Meters, Yards, Feet, and from Feet back to
Points. Each press is one undo step, and the reply names the new
units. Keyboard Shortcuts lists it under Document.
The precise cursors shortcut-editor test used Cmd+Alt+Shift+U as a
free key; it now uses Cmd+Alt+Shift+Q.
Docs: docs/mcp.md, docs/ui-parity.md, docs/target-app-parity.md.
With the Width tool, Escape did not deselect the selected width points:
they stayed selected, Delete still removed them, and in isolation mode
the same Escape left isolation mode. The reference app's shortcut list
gives Esc for deselecting a width point.
Escape now deselects the Width tool's selected width points. The path,
its widths and the undo history do not change, and no command is sent.
While width points are selected the tool takes Escape, so that Escape
does not also leave isolation mode. With no width point selected, and
during a drag, Escape does what it did before.
Docs: docs/mcp.md, docs/target-app-parity.md.
The reference app switches an arc between open and closed with C,
flips it with F and changes its angle with Up/Down while it is dragged
out. VectorCraft's Arc tool ignored these keys during a drag.
While an arc is dragged out, C now switches it between an open and a
closed path, F switches its base between the X and Y axes in the same
box, and Up/Down raise and lower its slope by 10 within -100 to 100.
Each press switches once. The arc drawn on release uses the new values,
and they stay as the Arc tool's options. With nothing dragged, C and F
are shortcuts as before.
Docs: docs/mcp.md, docs/target-app-parity.md.
The reference app switches the Blob Brush to the Smooth tool while Alt
(Option) is held. In VectorCraft an Alt drag with the Blob Brush painted
a blob like any other drag.
With Alt held at the press, or pressed before the drag has moved, the
Blob Brush shows the Smooth tool's cursor and a thin line without the
length label, and the release smooths the selected paths under the
drag with path.smoothRegion, as the Pencil does when Alt key toggles to
Smooth Tool is on. Shift does not constrain a smoothing drag, a stroke
that has moved keeps painting when Alt goes down, and with nothing
selected the release changes no path.
Choosing another tool during a Pencil smoothing drag no longer leaves
the Pencil showing the Smooth tool's cursor when it is chosen again.
deactivate now clears the smoothing state, for the Blob Brush too.
Docs: docs/target-app-parity.md.
edit.colors.saturate's params text names intensity as required, but a
call without it, or with a string such as "40", read the intensity as
0 and still ran Saturate. It changed no visible color but recorded a
Saturate undo step.
edit.colors.saturate now reads intensity with f64_req, as shape.ellipse
reads its box. A missing, null or non-number intensity is the error
"missing number `intensity`", which changes nothing and records no undo
step. A number outside -100..100 still counts as its nearest end, and
the params text says so.
Saturate returns a color whose saturation stays the same, as at an
intensity of 0, as it was. The HSB round trip rewrote most such colors
in their last bit, so they counted as changed and lost their swatch
link.
In the same file, edit.colors.adjustBalance read a channel that is not
a number as 0, and color.harmony read steps or amount that is not a
number as its default. Both now refuse it with check_numbers, as the
commands docs/mcp.md lists for #1952 do. A null is still read as a key
left out.
