MCP stdio is newline-delimited JSON, so one tool result is one message
and has to fit the client's read buffer whole; there is no streaming of
part of one. The TypeScript SDK's stdio transport defaults to 10 MiB and
hosts rarely raise it, so a document whose tree went past that killed
the server: the client stopped reading, the pipe broke, and every later
call in the session failed.
The tree is now reported at the deepest depth that fits, found by
bisection, with a `truncated` object giving the depth asked for, the
depth used, both sizes, the limit and a pointer to get_node for reading
one subtree deeply. `maxBytes` lets a caller that knows its own buffer
say so; the default is 8 MiB, leaving the envelope 2 MiB of the usual
10.
The size is measured as the transport sends it -- pretty-printed and
then escaped inside the text block, which adds about a tenth (342,136
bytes of tree became 379,954 on the wire in the fixture). A kilobyte is
reserved for the marker itself, which is added after the measurement.
A limit below even the shallowest tree still answers, at depth 0, with
the marker saying so: there is nothing smaller to send, and an error
would leave the caller with nothing at all.
The tool description now says that each level of depth multiplies the
response and points at get_node, which the report notes would have been
enough on its own to avoid the crash.
Fixes#912.
Duplicate and Alt-drag copied a main component as a second main. Within
its file the copy is now an instance of it (components::copy_in_file,
shared by edit.duplicate and the Alt-drag copy), as Copy then Paste
already was. A variant duplicated in its set stays a new variant.
Layer data written with node.set {props: {pluginData}} was saved but no
command read it back. node.get (the command, the control method and MCP
get_node) and document.inspect now report pluginData as {key: value}
when a layer or page has any, so a tool keeping state in a file can
read it on its next run. Widget keys are included: the plugin rules
only stop plugins writing them, and widget.list already reports that
state.
Alt+arrows were left out of the nudge keys, so with Alt held to measure
the arrows did nothing and the distances never changed. The arrows now
nudge with Alt held too (Shift: the big step); the hover measurement is
recomputed every frame, so the labels follow each nudge. While measuring
to another layer the selection's handles and size label hide; both
layers keep their outlines.
The dim text token (disabled buttons, placeholders, hints) was 2.1:1 on
the light theme's panels; disabled buttons also faded to 40% opacity,
and selected text was drawn in the dark green, 1.4:1 on the dark
theme's selection highlight. The dim text token is now at least 3:1
against panels, fields and selected rows in both themes while staying
dimmer than secondary text, a disabled button is grey with that text,
and selected text takes the theme's readable green. A test checks the
ratios with the colour contrast helper.
The browser has no system fonts, and since releases moved to the shared
workflow the web build was made without craft-fonts: no font list and no
text drawn. The Georgian change also re-pinned craft-fonts to its main,
which has no fonts/latin-manifest.txt, so the next release would fail
under CRAFT_FONTS_REQUIRED. Pin the Latin commit again until one commit
has both (craft-fonts#42); desktop Georgian uses an installed font.
