answer_dialog sent ui.dialog.set and then ui.dialog.confirm or
ui.dialog.cancel as two requests. A dialog another control connection
opened between them was confirmed or canceled without the fields.
ui.dialog.set takes `action: confirm | cancel`, checked before any field
is set, and confirms or cancels the dialog the fields were set in within
the same request, replying {dialog, result}. answer_dialog sends set and
action together; an app whose reply has no `dialog` key did not answer
it, and the dialog is then confirmed or canceled with its own request.
engine.commands, command_list and list_commands now list an inputSchema
next to schema for each command with a parameter schema. It is the same
JSON Schema 2020-12 schema with the root type "object", the form an MCP
tool's inputSchema takes
(https://modelcontextprotocol.io/specification/2026-07-28/schema);
schema keeps the root type ["object", "null"] when no parameter is
required. A command without a schema lists neither field. tools/list is
unchanged, and the commands are still run with command_run or
run_command.
brief now leaves out schema and inputSchema as well as the params text;
a listing filtered to the command's id gives them.

File › Open With asks for the parameters of an importer that declares
any, at their defaults, once the file is picked (dialog `pluginImport`),
and opens the file with the values set. `file.openWith`, `app.open` and
MCP's `open_file` take `params` and pass them to the importer;
`app.open` without them runs the importer on their defaults, with no
dialog. A file opened with Open With is added to Open Recent, as File ›
Open adds the files it opens.
open_file passes `importer` (an importer plug-in's format id,
plugin.<id>) on to app.open. Headless, it becomes document.open's
`importer`; in the app, app.open with `importer` runs file.openWith, so
the file opens with that importer as File > Open With does, also when a
built-in format reads its extension.
save_file's note for a key in `options` that the written format doesn't
read named every .ai file a PDF-compatible .ai, also when the save wrote
a version 7 file (`aiVersion: "7"`) or one without PDF content
(`pdfCompatible: false`).
The save itself now writes that note, beside its note on a top-level
`compress`, `version`, `preview` or `precision`, and names the file it
writes, including when it reuses the options the document was last saved
with. save_file returns the save's reply unchanged, and
`run_command document.save` and the other save commands give the same
notes.
A `backquote` given as a string or a number, on the request or on an
event, was read as absent, so `"true"` moved the object's geometry
instead of its pattern. `pointer_gesture` and `ui.pointer`, headless
and desktop, now answer with an error before any event runs.
Holding backquote while dragging with the Selection tool (move, bounding-box
scale or rotate) or the Rotate, Reflect, Scale or Shear tool applies the drag
to the selected objects' pattern fills and strokes and leaves their geometry
in place. The key state at release decides the result: the key may be pressed
after the mouse button goes down, and releasing it before the button comes up
commits an ordinary transform. Objects without pattern paint do not move.
PointerEvent gains a `backquote` flag (false when absent). The desktop canvas
reads it from the held key on every pointer event, and `ui.pointer` and the
`pointer_gesture` tool accept it per event or as a default for the gesture.
