Fix #6430: validate MCP path effects before creating text - #6447
Validate add_text's pathEffect before creating text. An unknown effect used to return an MCP error after replacing the source path, changing the selection, and adding an undo entry. The tool now rejects malformed effects and effects supplied outside type-on-path mode before editing.
Reproduced the error and document change over the Windows headless CLI's stdio MCP interface.
Ran five focused add_text unit tests on Windows. The new regression checks the path, selection and undo history after rejection, then applies skew to the same path as a valid control.
Strict MCP Clippy and the formatting check passed on the current merge.
Checklist
cargo xtask ci passes.
No panics or unchecked indexing added to shipped code.
The regression uses original synthetic geometry.
No new assets.
Summary by CodeRabbit
Bug Fixes
Invalid text path effects are now rejected before the document is edited. Path effects are accepted only for text created on a path, and supported effects are applied correctly.
Documentation
Clarified when text path effects can be used and that invalid effects are rejected.
You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.
Walkthrough
The add_text handler now validates pathEffect and its path context before creating text. Tests check that invalid inputs leave the document unchanged and that "skew" is recorded for text on a path. The documentation describes the validation.

Summary
Validate and apply pathEffect crates/mcp/src/tools/handlers.rs, crates/mcp/src/tests.rs, docs/mcp.md
The handler validates pathEffect and its path context before creating text, then uses the validated effect when applying it and checking overflow. Tests check that invalid inputs do not change the document and that "skew" succeeds for text on a path. The documentation describes the validation.
Invalid path effects are rejected before text creation, and the regression test checks that rejection leaves the document unchanged. No merge-blocking issue remains from this review.

Explanation
[#6430] add_text parses pathEffect and rejects unknown values, non-string values, and effects outside type-on-path mode before calling text.createInPath or text.create. The regression test checks that rejection preserves the document state, then confirms skew succeeds and appears in the document output. This meets the issue’s preservation and valid-control requirements.
Full details: Description check
Explanation
The description follows the template's two content sections. "What and why" explains the change: rejecting invalid pathEffect values before editing, and links issue #6430. "How it was tested" lists reproduction over the Windows headless CLI, five focused add_text unit tests, and a Clippy and formatting check. The checklist is partly ticked, and the first item, cargo xtask ci, is unchecked, with no explanation. The description does not state whether the full CI run passed, and it does not mention the no-panic rule beyond a checkbox. The objectives say all 12 CI steps passed on Windows, but the description does not say so. The asset item is ticked as not applicable, which is consistent with the diff.

@bflatastic could you review this fix when you have a chance? It validates MCP text path effects before creating text, so invalid input leaves the document unchanged. The focused regression tests and local cargo xtask ci passed. Please let me know if you would like any changes.

Reviewed the full diff at ffd5278, including the PathEffect parser, text.createInPath mode handling, type.pathOptions, overflow reporting and the regression test. No actionable defect found in this change. Validation now happens before path replacement or selection/history changes, uses the same parser as the engine, and retains the supported onPath/path aliases. The regression covers malformed effects and effects outside path mode, plus a valid skew control.
Validation is not complete: the focused add_text tests are still compiling on the designated Windows test host. I have not independently verified the reported full cargo xtask ci pass; the current GitHub check rollup contains CodeRabbit only. Posting a comment rather than an approval until build/test validation is available.
…xt slice
script_pump read vectorcraft_doc::cancel only after the guard that keeps
a run waiting, so a run asleep in $.sleep went on waiting until its wake
time (up to 1,000 ms), and a run waiting at a dialog or for approval to
grow waited until someone answered. The check now runs before that
guard, after the dialog-failure check, so a canceled request ends the
run at the next slice and every document goes back.
action.batch read its true/false options with a fallback, so
{"stopOnError": "false"} kept stopping on the first error, and a
number for a string option such as label or datasetFileNaming was
dropped or turned into an empty string. The source check also ran
after the destination folder was made.
includeSubdirs, overrideOpen, overrideSave, overrideExport and
stopOnError now take only true or false, and source, folder,
destination, destinationFolder, datasetFileNaming and label take only
a string. Any other value is an error naming the key, given before the
destination folder is made or a file is opened. A null reads as a key
left out. The params text and docs/mcp.md say so.
…quare
A new gradient kind, `diamond`, runs its stops from the center (the
start) out to a square with a corner at the end of the vector; the
aspect stretches the square across the vector into a rhombus. The
Gradient panel's Type row has a Diamond button, the Gradient tool draws
the square with the aspect handle and center ring, and a gradient
fitted to an object covers its box.
- Model and canvas: the level is |x| + |y| in the square's frame; a
square with no area (no vector, an aspect of 0, numbers out of range)
paints the last stop. The canvas draws it as pixels, out to a
stroke's miters, caps and arrowheads. Transforms keep the vector and
take the mapped size across it as the aspect.
- Commands: `paint.setFill`, `paint.editGradient` and
`paint.setGradientGeom` take `kind: "diamond"`; a negative aspect or
a focal point is an error. A conic or diamond gradient that a plug-in
returns with a focal point loses the focal point.
- Gradient tool: dragging the aspect handle of a radial or diamond
gradient whose file gave it a negative aspect now sets a positive
aspect; only a conic's negative aspect mirrors it.
- Export: PDF, SVG, EPS and legacy .ai write four linear gradients, one
for each quarter of the square, clipped to the shape (PDF as axial
shadings). PDF and SVG write an image for translucent stops, a
dithered fill or a flat square, and for the Perceptual method unless
PDF writes the stops as spot color shadings. SVG writes a diamond on
type characters as a radial gradient through the corners, and so
does CSS. A swatch library saved as CSS gets four corner layers, a
value for the `background` property (a circle when the swatch is
turned by an angle that is not a multiple of 90 degrees). The .ai
editing data holds a radial gradient through the corners. The
document exports give a warning.
- SVG export: a stroke drawn as an image, as conic wedges or as diamond
quarters now covers the miters, caps and arrowheads that reach past
its paint box.
- PDF import reads a function-based shading whose color is the same
along each square about the origin of its space as a diamond.
- Object > Expand gives nested squares or a mesh of rings.

… was on
A save that set useArtboards: true and named an artboard with artboard
or artboards, without range, wrote that artboard, but file.formatOptions
reported the default range. The Save As dialog then opened on All, and
OK saved every artboard. file.formatOptions now reports those artboards
as the range unless Use Artboards was saved off.
…against the heap limit
Flattening a concatenated string copies its units into a new buffer. The
string built-ins reserve that copy with flat_charged, but several other
paths flattened without it, so a script could build copies the heap limit
never saw:
- the relational operators (`<`, `>`, `<=`, `>=`) on two strings, `==`
between a string and a number, unary `+` and every other ToNumber of a
string, and reading a character by index (`s[0]`)
- a property name made from an object whose toString returns a long
string, and a long string used as a property name, which now reserves
its copy before it is made instead of after
- direct `eval` of a concatenated source
- `JSON.stringify` of a string value and its `space` argument
- `Array.prototype.join`'s separator and each string element it writes
Property names and eval source reserve the copy's heap bytes without
taking fuel.
A for each loop read the property's value before evaluating its target,
so a target such as (o.p = 2, t).v, t[(o.p = 3, 'w')] or a bare
@[(o.p = 2, 'k')] stored the value from before the target ran. The
target's object and name are now evaluated first and the value is read
after them (ECMA-357 section 12.3).
…r characters as live type
Type in a font found by name with a predefined non-Unicode CMap, such as
`/Ryumin-Light-83pv-RKSJ-H findfont` or a `composefont` with `GBK-EUC-H`,
opened as Latin-1 letters (`ú{A` for 日本A) in a font whose style carried
the CMap name (`Light-83pv-RKSJ-H`). Only Unicode CMaps were split off the
font name, and `composefont` failed with `undefinedresource` for the others.
- The predefined CMap decoder used by legacy `.ai` type moves to
`import/predefined_cmap.rs`, and EPS import decodes these CMaps' codes
with it (Shift-JIS, EUC, GBK, Big Five, UHC and the other public CMaps).
- A font name splits at a predefined CMap unless an installed face has
the whole name. A CMap that can't be read gives a warning.
- Type over a vertical CMap (`-V`) is set as vertical type, and each code
moves the point one em down the column, the default `DW2`
displacement.
- Every show operator sets decoded type with the same spacing and shaping
as other fonts found by name.
- Decoding a string counts against the import's memory budget.
Rewrap the prose in docs/plugins.md whose lines broke well short of
the file's 120-column width or ran past it, including the Safe Mode
sentence, the permission-name and install-confirmation sentences, and
the grants.json paragraph. Each rewrapped line is at most 120 columns.
No words, punctuation, code blocks or tables change.
