* feat(code): link code to canvas layers and underline design issues
Code in the Code tab and layers on the canvas were unrelated: finding the
element behind a layer, or the layer behind an element, meant reading names.
Generated Design JSX and Tailwind JSX report the layer behind each element
in the order elements open, and edited Design JSX keeps the source line of
every element through the sandbox and renderer, so hovering an element
highlights its layer, Cmd/Ctrl-click brings it into view without changing
the selection the code shows, and errors and warnings from the design check
are underlined on the property that causes them.
* feat(code): explain the Code tab when nothing is selected
With no selection the editor showed a starter frame that read like a real
layer. The tab now says it shows the selected layers' code and offers Write
JSX, which opens the editor focused on the starter template.
* refactor(code): group code-to-layer linking into its own domain
Layer link types, issue mapping, and the hover and reveal behavior move
from the Code panel and a component file into src/app/code/layers, with
useCodeLayers as the panel's entry point, so app code no longer imports
types from components.
* fix(code): underline off-scale gaps after the spacing rule renamed its property
* feat(code): mark the layer of the element around the cursor
Hover highlighting and ⌘-click reveal replaced by one model: the element
around the cursor marks its opening and closing tag names and outlines its
layer on the canvas while the editor has focus. ⌘-click also collided
with CodeMirror's add-a-cursor gesture. Read-only Tailwind JSX now takes a
cursor so it links the same way.
Leaving the editor now ends a live Design JSX edit as one undo step.
Before, canvas edits made after typing never reached the code until the
tab was reopened, and their undo entries landed before the edit's.
* feat(code): sync the Code tab and the canvas both ways by patching
Canvas edits now patch the Design JSX a person wrote instead of waiting
for them to leave the editor: each linked element remembers the layer as
Design JSX last wrote it, and a canvas change rewrites only the attributes,
text and child elements that differ from that base, as CodeMirror changes
that keep the cursor, comments, formatting and history. Attributes written
as expressions are never overwritten; the code marks them when the canvas
now differs. Untouched code is regenerated with a minimal text change.
Code edits update layers in place: the new render is reconciled into the
existing layers (reconcileRenderedLayers), which keep their ids, so links,
selection and canvas edits survive typing. Each edit is one coalesced undo
step, replacing the restore-and-rerender preview and the commit on blur.
* feat(code): patch reordered layers and aliased properties in edited code
Reordering layers on the canvas now moves their elements in code a person
wrote: each child element and the blank lines and comments above it form a
block kept as written, and the children are written again in the new
order, staying linked. Children that cannot move safely, such as a loop
between them, keep their order and are marked.
Properties accepted under several names now come from one alias table in
the Design JSX schema, which the renderer resolves through and the patcher
and issue underlines use, so a canvas change to `w` patches `width` where
the person wrote that, instead of adding a second attribute.
* feat(code): keep the cursor in moved code and patch values written in style
A reorder rewrites the children span in one change, which collapsed a
cursor or out-of-sync marker inside a moved element to the span's edge.
The patch now carries where each block moved and places selections and
markers inside it at their new position.
Properties the renderer also reads from style={{ … }} come from a table in
the Design JSX schema instead of a hand-written list, keeping the rule
that an attribute under any of its names wins. The patcher uses it to
update a value written in style where it is, as a number or a px string
as written; values the renderer cannot read, such as '50%', are marked.
The layer patcher is split by concern: syntax helpers, attribute and
style patches, child patches, out-of-sync state and transaction assembly.
* feat(code): show the code's layer on the canvas as a tinted box
The layer of the element around the cursor used the canvas hover slot, so
moving the pointer over the canvas replaced it and the two read the same.
It now has its own shared editor state, codeFocusNodeId, drawn as the hover
outline over a light tint in every pane: hover stays an outline and the
selection keeps its handles, without borrowing the dashed outlines that
already mean component sets, drag parents and ghosts.
* fix(code): write added and removed layers when a reorder cannot move the code
When children could not be moved, such as two written on one line, the
patch marked the order and returned before adding or removing elements,
so a layer created in the same change never reached the code. It now
marks the order and still writes additions and removals.
* refactor(design-jsx): format the rebased layer description and stroke aliases
* feat(code): mount the layer-linked code editor through useCodeMirror
Master moved the code editor onto the shared useCodeMirror composable.
Its layer links, issue underlines, canvas patches, minimal text updates,
autofocus and read-only cursor now sit on that composable instead of a
hand-mounted view.
* feat: check designs live with a Check panel and canvas issue markers
Design lint only ran from the CLI and AI tools, and its rules were too noisy
to show continuously: on a real imported page 786 of 888 layers had a
warning. The rules now report where a finding is actionable (a hardcoded
color only when a variable matches it, nesting only where the limit is
crossed, instance sublayers through their main component) and carry
structured data, and Recommended keeps warnings for likely problems.
The app checks the current page after edits settle. The Check tab groups
issues by rule with hover highlighting, reveal on click, and one-step
variable binding. Errors and warnings are marked on the canvas with
clustered markers that roll up to visible ancestors when zoomed out; markers
explain themselves on hover, open Check on click, and toggle with
View > Design issues.
* fix: keep the right panel and markers stable
The Check tab made the right-panel tab row overflow at common window widths,
so focusing the zoom menu scrolled the row and shifted the panel. Code and
AI tabs now drop their labels to screen readers when the row is narrow.
Touch target names are matched as whole words: "Rectangle" contained "cta"
and marked every rectangle. Markers also stay drawn during interactive edits
instead of blinking while a value is scrubbed.
* fix(ui): show right panel tab labels whenever they fit
* fix(ui): name the design check tab Lint and keep panel tabs consistent
The tab was an unlabelled icon between labelled Code and AI tabs. It is now
Lint, with the same icon and label anatomy as its neighbours, and its icon
takes the severity color instead of a count badge. All labelled tabs show
their labels when the row fits and drop them together when it does not.
* refactor(ui): build the Lint panel from shared components
Issue groups use AppCollapsible, actions use AppButton, and the severity
filters are a Reka toggle group with keyboard navigation. Issue rows no
longer nest a button inside a button. Panel state, visibility and the
focused-issue scroll live in useDesignCheckPanel, the rules menu is its own
component, and rule preferences change through preference actions.
Severity ordering reuses Core's ranking, detail numbers follow the app
language, and the check debounce uses useTimeoutFn.
* fix(lint): check the WCAG AA touch target size in the Recommended preset
Recommended flagged a 394 × 39 input because it required the 44 × 44 AAA size. It now checks the 24 × 24 AA minimum through a minSize option; Strict and Accessibility keep 44 × 44.
* feat(lint): fix design issues from rules, the Lint panel, the CLI, and agents
Rules attach fixes as data: a safe fix keeps the design as it looks (bind a
color to the variable it matches, round subpixel geometry that layout does
not own), a suggestion changes values (snap radius and spacing to the
scale, raise small text to the minimum). One Core applier re-validates
each fix against the current graph and merges changes per layer.
The Lint panel offers a fix per row and Fix all for safe fixes as one undo
step; openpencil lint --fix writes the fixed document; the lint and
lint_fix tools expose the same to MCP and AI chat.
The design-check spec's Close button is now 24 x 20: at 24 x 24 it passes
the WCAG AA touch target size that Recommended checks.
* feat(lint): pin issues outside the view to the canvas edge
Errors and warnings on layers outside the viewport had no marker, so a
check could report issues nobody could see. They are now pinned to the
canvas edge where a ray from the viewport center toward them leaves it,
with a chevron pointing their way; pins in one direction merge like
markers. Hovering lists them under the direction they lie in, and
clicking reveals and opens the most severe, nearest one.
Pins keep clear of UI floating over the canvas: the toolbar marks itself
with data-canvas-obstacle, and canvases report such rectangles to the
renderer through getOverlayObstacles each frame.
* feat(lint): mark layers with design issues in the Layers panel
Like an IDE marks files with problems and the folders holding them, a
layer with errors or warnings shows the most severe as an icon, and a
collapsed layer with issues inside it shows a dot in that color.
Suggestions stay in the Lint panel, as on the canvas, and the marks
follow the View → Design issues toggle.
* feat(lint): show issues per page and across the document
Loaded pages beyond the current one are now checked in the background,
one page at a time while the editor is idle, and checked again only when
an edit touches them; pages a large .fig file has not loaded are left
alone until opened rather than forced in. The page list shows each page's
errors and warnings like an IDE's problem count, and the Lint panel gains
a Document scope that lists every page's issues, tags the ones on other
pages, and switches to a row's page when it is opened.
* test(lint): use the core-tests alias and no comma operator in lint tests
Master now rejects ../../ imports and the comma operator in tests.
* refactor(app): create the Lint session with the editor store modules
The composition root passed its line budget once master added recent
pages; the Lint session belongs with the other per-editor services that
the modules factory creates and disposes.
* docs(changelog): keep master's latest Unreleased entries
* ci: run CI and the PR title check for the merge queue
A merge queue tests each queued change on top of the ones ahead of it and
waits for the required checks, CI result and PR title, on that merge
group. Both workflows now run on merge_group, reading the base and head
from either event. The title was checked on the pull request, so the
queue run reports success without a title to read.
* docs: explain stacked pull requests and the merge queue
Agents had to be told what a stacked pull request is each time.
CONTRIBUTING.md now covers stacks with gh stack, keeping them linear,
and landing them through the merge queue; AGENTS.md links to it, and
tools/AGENTS.md records that required checks must run on merge_group.
* docs: shorten the stacked pull request and merge queue guidance
The AGENTS.md line loads into every agent context, so keep it to the
rules; CONTRIBUTING.md keeps the commands.
* feat(scene-graph)!: make a stroke a paint
Stroke extends Fill, so a stroke carries the same paint vocabulary a
fill does instead of a lone color. Every construction site now states
a solid paint type, which keeps today's behaviour exactly; rendering,
.fig conversion, and the stroke panel still read solid strokes only.
copyFill is generic over the paint shape so copyStroke reuses it
rather than repeating the deep copy of gradient stops, transforms and
pattern fields.
Groundwork for the gradient and image strokes in #797.
* test(scene-graph): cover a stroke's nested paint data in copyStroke
A stroke is a paint now, so its gradient stops and transform must copy
as deeply as a fill's; the fixture was solid and proved only the color
and dash pattern.
Figma draws the value a bound paint or number stores until something makes
it resolve the variable again. OpenPencil resolves bound colours only when
drawing, so exports wrote the colour from before the binding, and a graph
bound without the editor kept stale numbers too: a file opened in Figma
showed bound fills in their old colour.
The exporter now writes each node with its bindings resolved, without
changing the document: colours as the variable's RGB at full alpha with
its alpha as the paint's opacity, which is how Figma stores them in every
fixture, and numbers in scene units. Nodes without an explicit mode take
the collection's default, because the mode the editor shows is not saved.
The resolution moves into scene-graph as resolvedPaintBindings and
resolvedNumericBindings, which the reader and reconcileNumericVariableBindings
now share, and the node resolvers take a fallback of 'active' or 'default'.
* fix(fig): keep variable metadata, plugin data and default mode on save
Saving a .fig rebuilt every variable record from the model, which held none
of Figma's variable metadata, so each save wrote variables as published to
all scopes with no description or code names, dropped other plugins' data,
and made the first mode the default.
Variables now carry scopes, codeSyntax and pluginData, collections carry
pluginData, and the reader and writer translate description,
symbolDescription, isPublishable, variableScopes and codeSyntax. Figma has
no default-mode field, so setting a default moves that mode first (undo
restores the order) and the writer orders the default first.
This is the base for design tokens: the CSS name will live in
codeSyntax.WEB and unit and mode conditions in OpenPencil plugin data.
* refactor(scene-graph): share the default-first mode order
setDefaultMode and the .fig writer both moved the default mode first by
hand; modesDefaultFirst does it once, with es-toolkit's partition.
* fix(core): undo a default mode change on the collection currently in the graph
Undoing a collection's removal restores a copy of it, so the inverse of
setDefaultMode wrote the previous order and default to an object the
graph no longer held when both were undone. Look the collection up by id
when undoing, as the forward step already does.
0.4.0 maps var() references to @theme variables onto their utilities,
which design-token export will use, and parses CSS values with
postcss-value-parser instead of regular expressions, fixing lossy
shorthand, filter, transform and media-query conversion.
* fix(scene-graph): leave a field a component property drives to its instance
A component states the default for a field a property reference drives,
but the enclosing instance's assignment decides the value. Synchronising
copied the default over it, so loading a page into an open document —
which synchronises every component it places — reset those layers. A
label a navigation item assigned came back as the component's default
when its page loaded on its own, while reading the whole archive gave
the assigned text.
Synchronising now skips a field whose reference names a property an
enclosing instance assigns, and carries everything else as before.
* fix(scene-graph): read an own assignment, not an inherited key
A document-authored component property id can collide with an Object
prototype key, and `in` would then report an assignment the instance
never made, silently leaving the referenced field unsynchronised.
* test(core): cover visibility and swap on an independent page load
The fix skips any field a component property reference drives, so the
page-scoped test should exercise VISIBLE and INSTANCE_SWAP alongside
TEXT rather than leaving the other two to full-document reads.
* fix(scene-graph): leave slot content to its own guard
#850 added a SLOT_CONTENT reference field, which drives a slot frame's
children rather than a scalar field, so the property-driven field map
no longer claims to cover every reference field.
* fix(vue): keep the command palette open when a command opens a step
CommandPaletteRoot emitted select for every item, including one that only opens its children, so a host that closes on select closed the palette instead of showing the step. useCommandPalette.select now reports whether a command ran, and the root emits only then.
Disabled items were marked only with Reka's data-disabled; expose aria-disabled so assistive technology announces them.
* feat(app): jump between pages from the command palette
The palette had no way to reach a page. It now lists the pages visited recently in the tab, offers a Go to page step with every page, and finds any page by name.
Recent pages are tracked per editor session from page changes and reset when the document is replaced. Palette items can be search-only, so pages beyond the recent ones appear only when the query matches them. The divider-page rule moves out of PageListRoot so the palette skips dividers the same way, and useCommandPalette is exported from the package root.
* feat(canvas): draw agents' cursors as outlined sparkles
Editor state's remoteCursors becomes presenceCursors with a kind, since the list now includes local agents. People keep the filled arrow; an agent is a sparkle outlined in its owner's color, with an outlined name pill, so whose agent it is reads from the outline. Cursor drawing moves out of the pen overlay into canvas/overlays/presence.ts.
* feat(app): publish AI agent presence to collaborators
The built-in chat now appears as an agent with a callsign while it replies, at the nodes its tools touch on the run's page, and goes idle (off the canvas) when the reply ends. Agents live in a per-document presence registry and are published in their owner's awareness state, so collaborators see each other's agents in the owner's color; the payload is metadata only.
Peer awareness was cast without checks. It is now validated with Valibot, invalid fields are dropped rather than the peer, and names, selections, and agent counts are bounded.
* feat(app): follow agents and list them in the share panel
Following lived in collab and only knew people. It moves into the presence registry with a person-or-agent target, so you can follow anyone's agent, including your own outside a room: the view goes to the agent's page and keeps its cursor centered, stays attached while it idles between replies, and lets go when it leaves. A new editor action, centerOn, replaces reading the canvas size from the DOM. Peer cursors keep their zoom so following a person still matches it.
The share panel lists everyone in the room with their agents, each with its status, page, and a follow toggle, and your own agents can be renamed inline. CollabPanel moves to collab-panel, and the two-browser relay helpers move out of the collab spec into tests/helpers/collab.
* feat(app): show who works on each page
Agents now publish the page they work on, set when a reply starts on its pinned page and moved by switch_page, so a page is marked before the agent's first edit. presenceByPage groups people and working agents by page.
The Pages panel marks those pages with people's dots and agents' outlined sparkles in their owner colors, the command palette names who is on each page, and the chat says which page a reply is working on, with Go to page, while you view another one.
* docs(collaboration): list the agent model among shared presence
* test(app): stories for page presence markers and the chat's run location
The run location notice reads app state, so it moves into
useChatRunLocation and the component takes the agent and page as props.
* test(vue): a canvas story for presence cursors
Storybook now serves CanvasKit, so a story can render the real canvas:
people's arrows and agents' outlined sparkles, with controls for names,
colors, and zoom.
* feat(canvas): mark agents with a sparkle label instead of a sparkle cursor
A sparkle on its own did not read as a pointer. Agents now point with
the same filled arrow as people, in their owner's color, and their
outlined label starts with a sparkle.
* refactor(app): split the collaboration theme by component
One 18-slot theme served five components that each used a few slots,
with variants that applied to one slot. Avatars, the share button, the
presence list, page markers, and the mobile presence popover now have
their own themes, exported as tv() like the rest of src/theme.
* fix(app): truncate an agent's status before its name in the presence list
In a narrow share panel the status kept its width and the callsign
shrank to its first letter.
* feat(app): right-align page badges in a trailing area of the page row
Presence markers followed the page name. The row now has a trailing area,
right-aligned with its own spacing, where markers and later page badges
go.
* fix(app): key page markers by person or agent, not by name
Two people with the same name on a page, such as two Anonymous peers,
gave page markers duplicate keys. Entries now carry a stable id.
AI SDK 7 has no 'media' tool output part; images are { type: 'file', mediaType, data: { type: 'data', data } }. After diff_visual, export_image, or any other image result, the next step's prompt failed validation with AI_InvalidPromptError and the chat run stopped. toModelOutput is now typed against the SDK's ToolResultPart output, and a test validates the resulting tool message with the SDK's own schema.
* fix(fig): read, render, and write Figma slots
Instances of a component with a slot showed the component's default
content instead of their own, and saving to .fig dropped slot properties,
their settings, and every instance's content.
Figma stores an instance's slot content as a frame on the internal canvas
and assigns the slot property that frame's GUID. The reader follows the
assignment while expanding the slot frame and pulls content frames into
the dependency closure without making them layers. The scene graph gains
a SLOT property type with its settings, a SLOT_CONTENT binding, and the
rule that an assigned slot's content belongs to the instance, which
component sync now leaves alone. The writer emits content frames on the
internal canvas and binds slot frames through the parameter map, as
Figma does.
The occurrence and diagnostic types move from the interpreter to
instance-overrides/occurrence.ts to keep it under the size limit.
* fix(fig): keep slot content through swaps and missing content frames
A slot assignment whose content frame the archive lacks no longer refuses
the document: the reader reports it through onMissingSlotContent, like a
missing component, and the slot keeps its component's content.
Swapping an instance's component, which variant switches do, now carries
the instance's own slot content to the new component's slot of the same
name instead of dropping it, as Figma does.
Component sync reads which slot a frame is from the component, whose
bindings instance copies do not receive. Clipboard export numbers slot
content after the other records on its dependency canvas, and the reader
and writer share Figma's default slot value.
* docs: note slot content kept across variant switches
* fix(fig): pair clipboard text by record and drop dangling slot assignments
The Figma clipboard paired text records with source text nodes by
traversal order, but instance-owned slot content is written after the
selected layers, so slotted text and the text after it swapped shaping
data. Records are now paired with their nodes through their GUIDs.
An instance assignment whose slot content frame is missing is dropped
along with the reported diagnostic, so the slot keeps following its
component instead of looking instance-owned.
* ci: pull the slots fixture for unit tests
* test: use GUID and Array.from in the slot tests
* refactor(fig): group occurrence types and paths in one folder
occurrence.ts and occurrence-path.ts became sibling prefixes when the
occurrence types moved out of the interpreter; they now live in
instance-overrides/occurrence/ as types.ts and path.ts.
* feat(canvas): draw agents' cursors as outlined sparkles
Editor state's remoteCursors becomes presenceCursors with a kind, since the list now includes local agents. People keep the filled arrow; an agent is a sparkle outlined in its owner's color, with an outlined name pill, so whose agent it is reads from the outline. Cursor drawing moves out of the pen overlay into canvas/overlays/presence.ts.
* feat(app): publish AI agent presence to collaborators
The built-in chat now appears as an agent with a callsign while it replies, at the nodes its tools touch on the run's page, and goes idle (off the canvas) when the reply ends. Agents live in a per-document presence registry and are published in their owner's awareness state, so collaborators see each other's agents in the owner's color; the payload is metadata only.
Peer awareness was cast without checks. It is now validated with Valibot, invalid fields are dropped rather than the peer, and names, selections, and agent counts are bounded.
* feat(app): follow agents and list them in the share panel
Following lived in collab and only knew people. It moves into the presence registry with a person-or-agent target, so you can follow anyone's agent, including your own outside a room: the view goes to the agent's page and keeps its cursor centered, stays attached while it idles between replies, and lets go when it leaves. A new editor action, centerOn, replaces reading the canvas size from the DOM. Peer cursors keep their zoom so following a person still matches it.
The share panel lists everyone in the room with their agents, each with its status, page, and a follow toggle, and your own agents can be renamed inline. CollabPanel moves to collab-panel, and the two-browser relay helpers move out of the collab spec into tests/helpers/collab.
* docs(collaboration): list the agent model among shared presence
* test(vue): a canvas story for presence cursors
Storybook now serves CanvasKit, so a story can render the real canvas:
people's arrows and agents' outlined sparkles, with controls for names,
colors, and zoom.
* feat(canvas): mark agents with a sparkle label instead of a sparkle cursor
A sparkle on its own did not read as a pointer. Agents now point with
the same filled arrow as people, in their owner's color, and their
outlined label starts with a sparkle.
* refactor(app): split the collaboration theme by component
One 18-slot theme served five components that each used a few slots,
with variants that applied to one slot. Avatars, the share button, the
presence list, page markers, and the mobile presence popover now have
their own themes, exported as tv() like the rest of src/theme.
* fix(app): truncate an agent's status before its name in the presence list
In a narrow share panel the status kept its width and the callsign
shrank to its first letter.
* feat(app): show presence and following on the toolbar avatars
The share popover held who was online, the Share button turned into a
Connected status, and following gave no feedback. Collaborators' avatars
now count their agents and list them on hover, your avatar holds your
agents and Leave room, and +N collects the rest. A frame and bar in the
followed color show whom you follow; your own input or Escape stops it.
The share popover keeps the room link, and Share keeps its label.
* fix(app): address review of following from the avatars
Escape stops following from the follow frame, once and not while typing
or after another control handled it. The frame shows the agent sparkle
as an icon. A test pins that following survives the target changing
pages mid-switch, and the test relay tolerates frames that are not JSON.
* fix(app): follow until you leave, wait for silent peers, reach agents by keyboard
Following records the page it put you on, so any other page change ends
it, even of a resting agent that would otherwise pull you back later. A
present peer without a cursor yet is waited for instead of dropped. The
room list button is always there, so keyboard users reach agents that
hover cards only show to the mouse. centerOn ignores points too far away
to represent, and the docs describe following from the avatars.
* fix(app): stop following on any zoom of yours, and keep follow switches from restarting
Keyboard and menu zoom changed the view without the pointer or wheel
input the frame listens for, so following kept going and later undid the
zoom; any viewport change following did not make now ends it. Cursor
updates no longer restart a switch already heading to the same page,
which could keep a slow page from committing. The room's connected
store is reactive, and agent rename starts on a single click.
* fix(app): never loop on a followed cursor's unknown page, and stop on zoom mid-switch
A peer's cursor could name a page this document lacks; following then
retried a switch that never moved, forever. Following now waits on such
cursors and only re-syncs after a switch that landed. A page switch
restores its viewport without viewport:changed, so your zoom during a
follow switch now stops following too.
* fix(app): cancel a loading follow switch when following stops
Stopping following, by Escape, your own input, or zoom, left a follow
page switch loading, which then took you to their page anyway. Stopping
now overtakes it with a switch to the page you are on.
* feat(core): add visual diff and patch apply tools
diff_visual renders two nodes at one scale through the existing raster export, compares them with pixelmatch, and returns the diff PNG with the changed ratio and region in source-node coordinates. It takes export_image's scale and maxEdge inputs. FigmaAPI gains a CanvasKit-backed raster codec and a pageId export option, so the app and headless CLI decode pixels and render nodes off the current page.
diff_apply applies diff_create and diff_show patches through the Figma API, validates every node before changing any, and supports dryRun and force. diff_show now simulates changes on a detached copy with the same property code. One serializer and parser back all three. diffDocuments compares two documents page by page by name path.
Image tool results now reach models as media with their metadata as text, for any tool rather than export_image alone. diff_create, diff_jsx, and diff_visual join the default AI tool set, and the diff tools are no longer hidden from WebMCP.
* feat(ai): show what each AI edit changed in its tool call
Reviewing an AI run meant reading tool output or undoing steps to see
what moved. Each document-changing call now rebuilds its page before
and after from snapshots taken around it, and diffs each top-level
layer's JSX with jsdiff, the same patch diff_jsx returns, to find the
layers it changed. After the call returns, the changed region renders
in both states at one size and pixelmatch highlights the difference.
The tool card opens on a Changes view with a before/after slider, the
pixel highlight, and a CodeMirror merge view of the JSX. Records are
saved with the conversation next to attachments.
Calls snapshot their page individually instead of through one shared
variable, so concurrent calls in a step no longer overwrite each
other's undo state. Core gains graphFromPageSnapshot for rebuilding a
past page state, diffPageLayersJSX and jsxPatch (now shared with
diff_jsx), renderRegionToImage for rendering two states of one region
pixel for pixel, and comparePNGs on the raster codec. Settings > Chat >
Change previews sets the stored image size or turns images off.
* feat(cli): add diff commands and agent diff guidance
openpencil diff create, jsx, show, apply, and visual run the Core diff tools on a file or the running app; apply writes back with --write or --output like eval. diff files compares two documents page by page and exits 1 when they differ.
The chat prompt asks the agent to edit in place and to verify risky edits against a reference copy with diff_jsx, diff_create, and diff_visual. The skill, CLI reference, MCP tool table, and a new Comparing Designs page document the commands and tools.
* feat(ai): render tool calls as summarized, highlighted cards
Every tool call showed only a status and its output as a JSON string,
so render calls hid their JSX, export_image dumped base64, and long
runs filled the transcript with identical rows.
A call now shows a one-line summary read from its input and chips that
select and zoom to the layers it touched, switching to the run's page
when needed. Expanded, it shows the JSX or script it wrote and its
JSON input and output in a read-only CodeMirror view, and exported
images inline. Render calls can be expanded while their input streams,
so the JSX appears alongside the canvas preview. Consecutive calls
beyond three fold into one row that keeps the latest call visible.
CodeMirror loads with the first expanded call. The code theme gains a
monospace fallback because the editor font variable is not always
emitted.
* feat(ai): let the chat AI diff its run against the starting state
The diff tools compare two nodes, so checking an edit meant cloning a
reference first, which the agent rarely did. diff_changes compares the
current page, or one node under it, with the page as it was before the
run first edited it, in diff_create's patch format. The app keeps that
page snapshot per run and exposes it through FigmaAPI.changeBaseline;
MCP and WebMCP have no run, so the tool is offered only to the AI chat,
where it is enabled by default and the prompt asks for it before
reporting.
* feat(core): diff and patch node trees as JSX attributes
diff_create, diff_show, diff_apply, and diffDocuments used a hand-rolled
`key: value` property format that covered about fifteen properties,
matched children by name path, and could not see moves.
Nodes are now projected to the attributes the JSX export prints, and
jsondiffpatch matches children (by ID or by name path) and detects
moves. Patches list `-`/`+` attribute lines per node plus moved, added,
and removed children. diff_apply checks every hunk first, applies
attribute changes through the renderer's prop handling, and changes only
the fields an attribute moves, so IDs, instance links, and other state
survive. diff_show takes JSX attributes instead of a JSON props object.
design-jsx gains sceneNodeAttributes, parseJSXAttributes, and
jsxNodeFields for this, and the export round-trip property table is
shared so every case is also diffed and applied. `diff files` loads its
documents in order so node IDs, and so its patches, are deterministic.
* feat(ai): report diff_changes as a patch diff_apply can replay
diff_changes printed a unified diff of the JSX, which agents could read
but not apply. It now diffs the run's baseline against the live page
with the patch engine, matching nodes by ID, so a rename is a changed
name and the output replays on the starting state with diff_apply. The
chat's Changes view keeps the JSX line diff, which is for people.
* fix(core): keep diff_apply atomic and diff files honest about differences
- Added nodes render before anything else changes; if one fails, for
example on a missing component, the rendered ones are deleted and
nothing else is committed.
- A hunk with an attribute the renderer ignores fails instead of
reporting "unchanged".
- diffDocuments reports `changed` from page statuses, and a page only
one document has gets its status but no patch, since patches do not
add or remove pages. diff files uses it, so an added empty page no
longer reads as a match.
- diff files rejects a --page neither document has and a --depth that
is not a non-negative integer, exiting 2; diff_create's depth is
validated the same way.
* refactor(ai): drop the unused tool JSON slot and place the JSX summary comment
* refactor(ai): find a tool change's clipping region with jsdiff
clipChangedJSX scanned both JSX sources character by character for their common start and end. diffLines gives the unchanged lines before the first change and after the last; the app now declares the diff dependency Core already uses.
* feat(ai): render tool calls as summarized, highlighted cards
Every tool call showed only a status and its output as a JSON string,
so render calls hid their JSX, export_image dumped base64, and long
runs filled the transcript with identical rows.
A call now shows a one-line summary read from its input and chips that
select and zoom to the layers it touched, switching to the run's page
when needed. Expanded, it shows the JSX or script it wrote and its
JSON input and output in a read-only CodeMirror view, and exported
images inline. Render calls can be expanded while their input streams,
so the JSX appears alongside the canvas preview. Consecutive calls
beyond three fold into one row that keeps the latest call visible.
CodeMirror loads with the first expanded call. The code theme gains a
monospace fallback because the editor font variable is not always
emitted.
* refactor(ai): drop the unused tool JSON slot and place the JSX summary comment
* fix(ai): keep an opened tool call in place instead of following the output
Opening reasoning already stopped the transcript from following new output; tool calls and tool groups did not, so expanding one near the bottom re-pinned the bottom on every animation frame and slid the card away as it opened. Any disclosure in the transcript now stops following.
* fix(ai): show a pointer over chat tool calls, tool groups, and reasoning
* refactor(app): share CodeMirror setup between the code editor and viewer
CodeViewer repeated CodeEditor's view lifecycle: mounting the EditorView, label, theme, and language compartments, the app-theme watcher, and teardown. useCodeMirror owns that once; each component passes its own fixed and reactive extensions.
* refactor(ai): move tool node lookup and focusing into useToolNodes
ToolNodeChips looked nodes up in the active document and ran the show-on-canvas flow, with its superseded-switch and error handling, inside the component. The composable owns both; the component renders the chips.
* refactor(ai): derive tool call state and input once
ToolCallCard and ToolCallGroup each rebuilt classifyToolState's input from the part, and the card decided inline whether a call had input to show. toolCallState and toolHasInput own those rules beside the other per-call helpers.
* fix(app): use the thin app scrollbar in code editors and viewers
CodeMirror scrolls its own .cm-scroller, which fell back to the platform scrollbar, thick and light in the dark chat. The hosts now give it the shared scrollbar-thin utility.
* feat(core): add visual diff and patch apply tools
diff_visual renders two nodes at one scale through the existing raster export, compares them with pixelmatch, and returns the diff PNG with the changed ratio and region in source-node coordinates. It takes export_image's scale and maxEdge inputs. FigmaAPI gains a CanvasKit-backed raster codec and a pageId export option, so the app and headless CLI decode pixels and render nodes off the current page.
diff_apply applies diff_create and diff_show patches through the Figma API, validates every node before changing any, and supports dryRun and force. diff_show now simulates changes on a detached copy with the same property code. One serializer and parser back all three. diffDocuments compares two documents page by page by name path.
Image tool results now reach models as media with their metadata as text, for any tool rather than export_image alone. diff_create, diff_jsx, and diff_visual join the default AI tool set, and the diff tools are no longer hidden from WebMCP.
* feat(cli): add diff commands and agent diff guidance
openpencil diff create, jsx, show, apply, and visual run the Core diff tools on a file or the running app; apply writes back with --write or --output like eval. diff files compares two documents page by page and exits 1 when they differ.
The chat prompt asks the agent to edit in place and to verify risky edits against a reference copy with diff_jsx, diff_create, and diff_visual. The skill, CLI reference, MCP tool table, and a new Comparing Designs page document the commands and tools.
* feat(core): diff and patch node trees as JSX attributes
diff_create, diff_show, diff_apply, and diffDocuments used a hand-rolled
`key: value` property format that covered about fifteen properties,
matched children by name path, and could not see moves.
Nodes are now projected to the attributes the JSX export prints, and
jsondiffpatch matches children (by ID or by name path) and detects
moves. Patches list `-`/`+` attribute lines per node plus moved, added,
and removed children. diff_apply checks every hunk first, applies
attribute changes through the renderer's prop handling, and changes only
the fields an attribute moves, so IDs, instance links, and other state
survive. diff_show takes JSX attributes instead of a JSON props object.
design-jsx gains sceneNodeAttributes, parseJSXAttributes, and
jsxNodeFields for this, and the export round-trip property table is
shared so every case is also diffed and applied. `diff files` loads its
documents in order so node IDs, and so its patches, are deterministic.
* fix(core): keep diff_apply atomic and diff files honest about differences
- Added nodes render before anything else changes; if one fails, for
example on a missing component, the rendered ones are deleted and
nothing else is committed.
- A hunk with an attribute the renderer ignores fails instead of
reporting "unchanged".
- diffDocuments reports `changed` from page statuses, and a page only
one document has gets its status but no patch, since patches do not
add or remove pages. diff files uses it, so an added empty page no
longer reads as a match.
- diff files rejects a --page neither document has and a --depth that
is not a non-negative integer, exiting 2; diff_create's depth is
validated the same way.
Switching pages again before the previous page finished preparing
aborted the first switch, which rejected with an AbortError. Callers
start page switches without awaiting them, so the rejection surfaced as
an error toast.
* feat(design-jsx): export every property the renderer accepts
JSX export wrote only part of a layer: one solid fill, one stroke
without its alignment, shadows as repeated attributes, background blurs
as layer blurs, and nothing for hidden children, constraints, size
limits, absolute positioning, vertical text alignment, masks, or
variable bindings. Rendering an export lost those properties, and JSX
diffs could not see changes to them.
The export now writes them, using paint and effect helper calls when a
shorthand cannot express a value exactly, and leaves out values the
renderer would infer, so ordinary output stays as it was. Prop values
can now hold objects, arrays, and helper calls, printed through
@open-pencil/codegen's builders, which gain a call expression. The
language gains `visible`, `locked`, `constraints` (Figma's constraints
object with lowercase values, as `blendMode` uses), `italic`,
`strokes`, `strokeWeights`, `strokeCap`, and `strokeJoin`, and now
applies `strokeAlign`, `strokeDash`, and the size limits, which it
accepted but ignored. Per-corner radii are written even when the
uniform radius is 0. A round-trip test renders each case's export and
checks the fields and that exporting again changes nothing.
* docs(fig): name the saved-glyph fixture by its repository path
The observation note linked the fixture with a relative path climbing four directories. Other notes name fixtures by their repository path, which reads the same from anywhere.
* fix(design-jsx): export the node-level dash pattern
A node's own dashPattern was not written, so a node dashed at node level
came back solid and the DOM/CSS export chose a solid border. It now
round-trips as a separate dashPattern prop; strokeDash stays the
stroke-local dash.
* feat(canvas): draw agents' cursors as outlined sparkles
Editor state's remoteCursors becomes presenceCursors with a kind, since the list now includes local agents. People keep the filled arrow; an agent is a sparkle outlined in its owner's color, with an outlined name pill, so whose agent it is reads from the outline. Cursor drawing moves out of the pen overlay into canvas/overlays/presence.ts.
* feat(app): publish AI agent presence to collaborators
The built-in chat now appears as an agent with a callsign while it replies, at the nodes its tools touch on the run's page, and goes idle (off the canvas) when the reply ends. Agents live in a per-document presence registry and are published in their owner's awareness state, so collaborators see each other's agents in the owner's color; the payload is metadata only.
Peer awareness was cast without checks. It is now validated with Valibot, invalid fields are dropped rather than the peer, and names, selections, and agent counts are bounded.
* docs(collaboration): list the agent model among shared presence
* test(vue): a canvas story for presence cursors
Storybook now serves CanvasKit, so a story can render the real canvas:
people's arrows and agents' outlined sparkles, with controls for names,
colors, and zoom.
* feat(canvas): mark agents with a sparkle label instead of a sparkle cursor
A sparkle on its own did not read as a pointer. Agents now point with
the same filled arrow as people, in their owner's color, and their
outlined label starts with a sparkle.
Reasoning effort was a free-text profile field that only reached OpenAI
and OpenRouter, so Anthropic, Google, and DeepSeek models never thought
in direct chat. AI SDK 7 standardizes a `reasoning` call option that
those providers map to their own thinking settings, so profiles now
store one typed thinking level, shared with Pi, and requests pass it
through that option. OpenRouter's provider ignores the standard option
and receives its own reasoning option instead.
The composer offers the level next to the Design profile and reads it
per request, so a change applies to the next message without
rebuilding the transport. Saved profiles migrate from the Pi level or
the old effort string. Finished reasoning shows how long the model
thought while the block streamed.
`bun run test` stopped before running anything. Moving Figma
observation records out of tests/fixtures also moved
styled-saved-glyphs.json, which the saved-glyph and occurrence-text
canvas specs import, so both failed to load. The record moves back to
the fixture tree, and its observation note links to it there.
The real-LLM smoke spec threw at import when OPENROUTER_API_KEY was
unset. `bun run test` excludes it by tag but still loads the file, so
the throw aborted the whole run. The key is now read when the test
runs, so `test:real-llm` still fails without one.
Three defects a confidential Figma file surfaced, each reproduced by a
test that fails without the change.
A page's background lived only in viewport state, so an imported canvas
colour never reached the canvas and an edit was lost on the next page
switch or save. It is read from and written to the page's paints, which
the Figma API and export already carry.
Fixed-size text in a Hug container reported no intrinsic cross-axis
size, so a stretched label collapsed and clipped beside smaller
siblings. Yoga now measures it.
Populating a page resynchronised an instance whose text the file had
already resolved, replacing it with the component's default.

CanvasRoot started CanvasKit on mount, but its CanvasSurface child hands
over the canvas element only afterwards, so startup found no canvas and
gave up. Wait for the element instead. Storybook now serves CanvasKit so
a story can render the SDK canvas.
`fig.kiwi` never defined the field, so nothing Figma writes carries one
and nothing OpenPencil writes has since `colorVar` replaced it. What
remained were readers kept so that files written by earlier OpenPencil
builds still restored their bindings — a compatibility path the project
does not keep before 1.0.
The field, the `VariableBinding` type and both readers are gone.
Reopening one of those files leaves the paint's colour unbound; binding
it again records it the way Figma does.
* fix(editor): keep the centered point when zooming to a fixed level
zoomToLevel found the world point at the viewport center, changed the zoom, then set the pan from that point without scaling it by the new zoom, so zooming to 100% from any other level moved the view away.
* fix(canvas): shape collaborator cursor names
Cursor names were drawn with Canvas.drawText, which neither kerns nor falls back to other fonts, so names like Orbit showed visible gaps. Draw them through the label paragraph cache like section and component titles, which also ellipsizes long names.
* fix(ui): drop icons from three canvas context menu items
Flatten, Outline text, and Outline stroke were the only context menu items with icons, so the menu looked uneven. The icon map also listed boolean operations that the context menu never shows; remove it.
* fix(app): cap the canvas menu width so long page names truncate
* refactor(codegen): share syntax-tree code generation between exporters
dom-css printed Tailwind JSX with its own esrap JSX builders and kept TypeScript template helpers under its Storybook export. The OpenPencil JSX exporter needs the same JSX builders, and design-jsx and dom-css may not depend on each other.
@open-pencil/codegen holds both: es for ESTree templates and modules (moved from dom-css) and jsx for JSX elements, attributes, text, and printing, including the literal rules that keep exported strings from being reinterpreted. dom-css no longer depends on acorn and esrap directly.
* refactor(design-jsx): print JSX export as syntax trees
sceneNodeToJSX concatenated strings with hand-written escaping and indentation. It now collects typed props (moved to export/props.ts) and prints them with @open-pencil/codegen's JSX builders. Output is unchanged except for text: special characters print as a string expression instead of entities, and multi-line text keeps its line breaks, which the old line-splitting lost on render.
* docs(codegen): fix package metadata and dependency rules
codegen's repository.directory still named design-jsx, the README mentioned es without showing it, and the design-jsx and dom-css guides still said they depend only on scene-graph.
* test(core): move the JSX export round-trips to the design-jsx test home
Covers tabs in layer names and text, which JSX keeps as written.
* fix(vue): keep the command palette open when a command opens a step
CommandPaletteRoot emitted select for every item, including one that only opens its children, so a host that closes on select closed the palette instead of showing the step. useCommandPalette.select now reports whether a command ran, and the root emits only then.
Disabled items were marked only with Reka's data-disabled; expose aria-disabled so assistive technology announces them.
* feat(app): jump between pages from the command palette
The palette had no way to reach a page. It now lists the pages visited recently in the tab, offers a Go to page step with every page, and finds any page by name.
Recent pages are tracked per editor session from page changes and reset when the document is replaced. Palette items can be search-only, so pages beyond the recent ones appear only when the query matches them. The divider-page rule moves out of PageListRoot so the palette skips dividers the same way, and useCommandPalette is exported from the package root.
* fix(vue): list every item in a command palette step
The result limit also applied to a step's unfiltered list, so Go to page showed only the first 12 pages. A step the user opened now lists all of its items until they search; search results and the top-level list keep the limit.
The palette spec's page setup and current-page observation move to tests/helpers/pages as a setup mutation, a probe, and a Pages-panel driver.
* test(pages): match page rows by exact name
* refactor(app): express page lists with es-toolkit
Recent pages are take(uniq([visited, ...previous]), max); the palette builds its lookup with keyBy and its lists with without, compact, take, and difference instead of hand-built maps, sets, and slices. Tests count with range.
Unbinding a fill or stroke and saving handed Figma back the variable
the layer was imported with: the raw paint kept its `colorVar` and only
the bound path ever touched it. The unbound path now clears it, and an
emptied bindings record is dropped rather than written, since nothing
reads an empty map and it would otherwise sit in every exported file.
With that, nothing writes `colorVariableBinding`. It had no entry in
`fig.kiwi`, so encoding one meant splicing bytes into the encoded
message by searching for marker sequences; exports have written
`colorVar`, the field the schema defines, since the reader landed. The
splicing encoder and the three helpers it exposed are gone, leaving
`parseVariableId`. Importers still read the old field, so files earlier
versions wrote still open.

* refactor(tools): group the oracle captures and mirror the bindings tests
Two names broke the rule that a multi-file domain gets a subfolder
rather than repeated sibling prefixes. `document-capture.ts` repeated
its own folder and sat beside `capture-scene.ts`, so both become
`document/capture/{document,scene}.ts` behind `#visual/capture/*`.
The document bindings tests were split between `document/binding/` and
a `text-bindings.test.ts` one level above, while their source is
`document/bindings/`. They move into `document/bindings/` and take the
source file names, so the test tree mirrors it.
* refactor(fig): group the node-change prefix families into folders
`node-change/` held five pairs of files sharing a leading segment —
derived-text, style, text, variable, vector — plus `instance-geometry`
beside an `instance-linkage/` folder. The guide asks for a subfolder
rather than a repeated prefix, so each becomes one: `style/{refs,runs}`,
`variable/{bindings,expression}`, and so on, with `instance-linkage/`
folded in beside `instance/geometry.ts`.
Imports across seventeen files follow. Two of the moved files reached
out of the package tree with `../../` once they were a level deeper;
those use `#fig/*` instead.
* fix(fig): give every layer on an exported canvas its own order key
Figma orders siblings by `parentIndex.position`. Shared styles, the
variable records and a canvas's own layers are written in three passes,
all landing on the internal canvas, and each numbered from the first
key — so up to five siblings claimed `!`. Exporting gold-preview left
402 records under one canvas with keys repeating up to five times.
Each pass now continues the keys already written for that canvas.
Counting them per canvas also covers the ordinary pages, whose layers
are written after the internal resources.
* fix(fig): keep the order keys a layer was imported with
Saving a document renumbered every sibling from the first key, so a
round trip rewrote positions Figma had assigned even where nothing
moved. A layer now keeps its imported key where that still orders it
after the previous sibling, and takes a key between its neighbours
otherwise.
Canvas children are excluded: shared styles and variable records are
written to the internal canvas by other passes that continue the keys
already there, so an imported key could collide with one of theirs.

* refactor(fig): look a sibling's order key up by id
`exportOrderKey` runs once per child and scanned the sibling list for
the node, so a parent with many layers cost O(n²) to export. The cached
entry now maps id to key directly.
Covers all three writers in the canvas test as well: an internal canvas
with its own layers, a shared style, and two variable collections, so
the pass boundaries that restarted a sequence are exercised rather than
only the page and variable passes.
* refactor(core): name the GUID type in the canvas order key test
---------

* test(core): move the fig round-trip suite into the package test home
The reader change added `verifier-contracts.test.ts` under
`tests/engine` and grew the migration baseline to admit it, which the
testing architecture forbids: new tests go to the canonical home and
the baseline only shrinks. It also started
`packages/core/tests/io/formats/fig/roundtrip/`, leaving two homes for
one domain.
These tests drive Core's exporter, so Core's home is the canonical one.
The directory moves whole — eleven files, its helpers and raw verifiers
with it — and picks up the local `assert`, `traversal`, `test-utils`
and fixture helpers already there. The baseline loses nine entries.
* refactor(core): address test helpers by alias instead of drilling
`open-pencil/no-deep-parent-relative-imports` already forbids `../../`
drilling, but `lint:structure` names the directories it checks and
`packages/{core,scene-graph,vue}/tests` were never added — so the 72
drilled imports in Core's tests, including the ones the round-trip move
just wrote, were never seen.
Core gains `#core-tests/*` beside fig's `#fig-tests/*`, registered with
the architecture rules, and its tests reach their helpers through it
and their source through `#core/*`. The three test directories join
`lint:structure`, which also surfaced six errors they had never been
checked for: four duplicated imports, an empty `noop`, and a
self-assignment the test meant, now written through a named binding.
Both guides state the rule, since a lint nobody can find in prose is
how this went unnoticed.
* fix(tools): point the heavy unit patterns at the relocated round-trip tests
`HEAVY_UNIT_TEST_PATTERNS` still listed the three heavy round-trip
tests under `tests/engine`. `test:unit` discovers them by directory so
the move looked clean, but `--heavy-only` selects by path and silently
stopped choosing them: 8 files, 52 tests, where it now runs 11 and 80.

* feat(fig): wire reader worker sessions and compact recovery checkpoints
* docs(fig): organize reader architecture and visual examples
* chore(fig): checkpoint WIP reader and writer overhaul
Preserve in-progress FIG reader, instance interpretation, editable export, and validation work on its feature branch. This is a backup checkpoint, not a release-ready or fully validated change.
* refactor(fig): resolve instance structure before expansion
Route swaps and property assignments down to the instance they configure
so each occurrence expands once with its effective component and complete
assignment list. Owners then apply property claims onto the built subtree,
which keeps values in the declaring owner's coordinate space and orders
inner owners before outer ones without re-expansion, recipes, or patch
restoration.
Track the components an occurrence expanded before an outer decision
replaced them, including intermediate swap assignments, so a claim that
resolved against a superseded component is retired while a genuinely
missing target still reports. Precedence is one rule: an explicit claim
keeps a field unless a strictly outer owner assigned it.
Drop the detached-lineage remap heuristic; unresolved assignments report
through the existing diagnostic instead of guessing a replacement target.
The Accordion source-closure fixture reports two stale overrides, not
three: the third came from a subtree the old interpreter expanded and
discarded.
* refactor(fig): derive override field handling from one registry
Describe each claimable raw field once, with its SceneGraph fields, kind,
and whether it is a length, and derive claim recording, layout-distance
scaling, and export serialization from it instead of maintaining parallel
tables.
Restore every field the uniform scaler touches from the instance record
after scaling. The record already describes the placed result, but corner
radii, dash patterns, and effects were previously scaled without being
restored, so a scaled instance with its own corner radius rendered it
doubled.
* fix(fig): retire nested swaps under a replaced component
A structural layer routed through an instance whose component an outer
owner replaced may still address the original component's children. Such
a layer is stale in the same way a property claim is: it resolved before
the outer decision and has no target now. Carry the replaced components
across that boundary and skip the layer instead of failing the file.
material3's List swaps a list item to another variant while the item's
own saved swap of a trailing checkbox still names the original variant's
child.
* fix(core): report stale Figma override records instead of refusing the file
Figma keeps override, assignment, and binding records that address nodes
it later deleted, and material3.fig could not open because the reader
ran the document session strictly. Share one set of session options
across the reader and recovery sessions that collects those records as
diagnostics and skips them; a swap whose replacement is missing remains
a structural failure.
The component-metadata expectation follows the visible Buttons page copy
of the component set, which the dependency closure now resolves instead
of an internal-only copy.
* fix(fig): keep instances of deleted components when opening a document
Figma retains instances whose main component was deleted, and material3's
Internal Only Canvas has 56 of them, so an edited document could not be
exported: export loads every page and the reader refused the page over
missing reachable sources.
The dependency closure now separates deleted components from broken
hierarchy, which remains fatal. With the new onMissingComponent option the
interpreter keeps such an instance as a childless occurrence that retains
its saved reference, applies only its root claims, and reports the owner;
strict interpretation still fails. The core reader opts in, shares one
diagnostics sink with recovery and export sessions, and exposes it through
readerDiagnostics(). Property defaults naming a deleted component are kept
the same way, so an edited export no longer rejects them.
* fix(fig): resolve variant property values through the component set
A variant's saved specs name variant definitions that its component set
owns, so occurrence conversion left them keyed by definition id. Resolve
them to names once the set is in the graph, as the previous importer did.
The component-metadata expectation follows the visible Buttons set's
axes; the Style axis belonged to an internal-only copy.
* refactor(fig): satisfy type-aware lint in the interpreter and export
* fix(fig): keep an instance fill override's variable alias across export
A fill or stroke override on an instance descendant lost its colour
variable on export: the paint claim was written without the alias, and a
boundVariables override for a paint colour produced no claim at all
because paint colours are not node-level consumption fields. The reopened
paint therefore bound to the component's default variable.
Write override paints through the same alias-aware builder as node
paints, serialize a paint colour binding override as the paint claim
itself, and on import record the binding claim alongside a claimed paint
that carries an alias so a later component sync cannot restore the
component's binding.
On an edited material3.fig round trip this removes all 10,329 fill
differences; 2,217 of 78,425 nodes still change, almost all text metadata
Figma keeps on outlined vectors.
* docs(fig): describe the single reader, its diagnostics policy, and paint claims
The status documents still said the replacement reader covered only some
worker paths and that old-reader removal was pending. Every import path
now uses it and the previous importer is deleted, so state that and move
the open items to fidelity and performance.
Record the contracts added recently: strict-by-default interpretation
with per-session diagnostic handlers that the application reader opts
into, instances of deleted components kept as childless instances, the
shared override field registry, paint colour aliases serialized inside
paint claims, and variant values resolved through the component set.
Correct the clipboard ownership rule in AGENTS.md: the envelope belongs
to fig, pasted records go through the same reader as documents.
* docs: note exported instance overrides in the changelog
* refactor(fig): share record indexing and symbol data access
Five modules built their own GUID-to-record index with the same idiom;
they now use the source index, or indexRecords when child order is not
needed. The Kiwi codec types only symbolID, so every reader cast
symbolData to reach overrides and the uniform scale; symbolDataOf,
symbolOverridesOf, and uniformScaleOf replace those casts. idOf and
parentIdOf name the record identity conversions used by ancestry walks.
* refactor(fig): share tree search and traversal across records and occurrences
The rule that a path segment may pass through ordinary containers but
never implicitly into an instance existed three times, once per tree.
findWithinBoundary owns it now, parameterized by a tree shape; the
occurrence resolver and the static record resolver are two callers.
An occurrences() iterator replaces hand-rolled recursion in the
component planner, closure, layout scaler, and correspondence linker,
forEachOverrideRecord replaces the record-plus-overrides walks in the
dependency scans, and one child-pairing generator serves both
source-children matchers.
* refactor(fig): serialize override claims from the field registry
Split export-node.ts: export-context.ts owns the serialization context,
GUID allocation, and paint builders; override-claims.ts owns instance
override serialization. The override serializer was a chain of field
checks that had to agree with the registry materialization records
claims from; it is now one switch over the registry's field kinds, the
export side of that table, with swaps and variable bindings as the two
cases the registry does not describe.
Decoded record streams for an edited gold-preview export and a
synthetic bound-fill export are identical before and after.
* fix(core): record instance overrides for FigmaAPI rename and resize
The name setter and resize() wrote to the graph directly, so a rename or
resize of an instance child through the Figma API was never recorded as
an override: component sync reverted it and export did not write it.
Route both through the shared recording update like every other setter.
* fix(fig): address overrides inside nested instances by the definition child
An override on a child of a nested instance was addressed through the
enclosing component's own copy of that child. That node lives inside an
instance and is never written as a record, so Figma could not resolve the
path and dropped the override. Follow the correspondence until it leaves
every instance, which yields the nested component's child, the record
Figma itself names in the same situation (verified against Figma's
clipboard encoding of the identical edit and by reopening the export).
* test(fig): record the Figma reopen of reader exports
* test(fig): compare reopened exports with the oracle tool
The interpreted-document comparison already reads Figma's interpretation
of an archive against the reader's; pointing it at an exported archive and
its imported Figma file makes it the reopen check. Captures need the
imported file to be the active document, so add an activate-tab operation
that brings a desktop tab to the front through the shell page. Record the
comparison results for the three reopened exports and document the
procedure.
* fix(scene-graph): keep a nested instance's correspondence across a swap
Children populated by cloning link to the enclosing component's record
through componentId. Swapping a nested instance replaced that field with
the new component, so the swap was exported against the replacement
component's GUID instead of the nested instance record and Figma could not
apply it. Record the correspondence as the owner's sourceComponentId
override and the swap as its componentId override, as materialized
documents already carry them.
* fix(core): treat applied shared styles as instance overrides
Style references were not instance sync fields, so a text style applied
inside an instance was neither recorded as an override nor exported, and a
component's style change did not reach its instances, although the reader
records styleIdForText claims from Figma. Add the style reference fields
to the sync set and expose them on the Figma API proxy under Figma's
names so assignments through the API record overrides.
* test: record the second Figma reopen round for the reader export
Figma confirmed stroke and corner-radius variable bindings, an applied
text style, nested-frame layout distances and sizing modes, visibility,
and a nested swap. A size claim on an auto-layout child inside an
instance is not applied, matching Figma's own resize refusal there.
* chore: format the merged structural export test
* refactor: group export and instance sync modules into domain folders
The node-change export context, node serializer, runtime, and override
claims move under node-change/export/, and the scene graph's instance
child sync and sync field lists move under instances/, keeping the
public instances module to its API.
* fix(fig): address exported instance overrides by override key
Figma resolves an override path segment through the target record's
override key, never its GUID: in gold-preview.fig all 10,341 override
and 12,838 derived-geometry segments resolve that way and none resolve
to a node GUID. A component imported from Figma keeps its keys, but one
authored here has none, so the writer addressed its descendants by GUID.
Figma tolerated that for most fields and silently dropped the geometry,
so a descendant resized inside an instance reopened at the component's
size.
Definition records — a component and everything inside it — now carry an
override key, minted from the shared identity counter when the node has
none, and paths name that key. One map spans the document because the
serializer runs once per top-level child.
The library content hash ignores the key, which identifies a record
rather than the component's content, and the clipboard export passes its
variable mode map as modeIdToGuid instead of propertyIdToGuid.
* docs: record how Figma resolves an override path
* Revert "fix(fig): address exported instance overrides by override key"
This reverts commit 38eebb2e5, except its clipboard argument fix.
The change came from gold-preview.fig, where every override path segment
resolves through a record's override key. material3.fig shows the
opposite: 51,332 of its segments are node GUIDs against 24 keys, and only
16 of 87,237 records carry a key at all. gold-preview is a file of
library instances, where the key is the cross-file identity; addressing
by GUID is what Figma writes for locally authored components, which is
what the writer already did. It was also not the reason Figma ignored a
descendant's size claim, which is still open.
The clipboard export keeps passing its variable mode map as modeIdToGuid
rather than propertyIdToGuid, which was an unrelated defect in the same
call.
* docs: correct the override addressing note and record the size gap
* docs: settle the descendant size gap as a Figma constraint
* chore: format the JSON fixtures this branch adds
format:check runs the formatter and fails on any change, so the fixtures
have to be committed as oxfmt writes them.
* test(tools): smoke the instance override subpath's current exports
populateAndApplyOverrides belonged to the importer this branch removes.
* perf(fig): index the archive once per document, not once per page
Selecting a page rebuilt both whole-document source indexes, so opening
material3.fig with its 33 pages indexed 87,237 records 33 times and
86,888 records another 33 times: 102 index builds where 36 are needed.
Only the page's own subset varies, so the full index and the component
interpreter move into state shared across selections, and the initial
read path passes its index to inheritance, style lookup, the dependency
closure and component planning rather than each building its own.
The paint and component-property passes iterate keys directly instead of
materializing an entry array for every node, most of which bind nothing.
Loading material3.fig goes from about 9.5s to about 7.5s on the same
machine, measured back to back with the machine otherwise idle.
* docs: note the faster multi-page .fig load
* perf(fig): apply document passes to the nodes a page materialized
Linking component property values, resolving variant values and applying
layout and paint bindings each walked the whole graph and skipped what
was already there, so every page load re-visited every node the earlier
pages had produced. On nuxtui.fig, 121 pages over a graph that reaches
354,000 nodes, those four passes were 22.7% of the profile after only
six pages and grew from there.
Each pass now takes the nodes just materialized. Component property
types are remembered across page loads instead, because an assignment on
a new node can name a definition an earlier page introduced; seeding that
cache is the only pass that still reads the whole graph, once per
document rather than once per page.
Pages 3 to 20 of nuxtui.fig fall from 90.0s to 51.6s. The first page is
unchanged: it materializes 256,354 nodes and is dominated by that.
* docs: note the per-page load improvement
* test(fig): keep the fig package suite off Core
Twenty package tests reached for Core's writer and editor through
@open-pencil/core, a package that depends on fig. Nothing declared that
edge, so the suite passed only because the workspace root hoists Core.
Their subject is the writer, so they move to tests/engine/io/fig, where
half the domain already spans both packages.
The package no longer escapes its own root: tsconfig drops the #tests/*
mapping, expectDefined is three lines beside the other helpers, and the
gold archive is read through the LFS-guarded fixture helper instead of a
hand-built ../../../../tests/fixtures URL.
#fig/ and #fig-tests/ join the steiger alias tables and the AGENTS.md
list, so the foreign-alias rule can see them. Fig's tests mirror its
source tree rather than sitting flat like kiwi's, so they address it by
alias instead of drilling, and the guid helper is imported one way.
* refactor(fig): drop code the reader replacement left behind
resolveDsdGeometry lost every production importer when the old derived
symbol data modules went, so it and the three tests that only exercised
it go too, and the folder collapses to one file. validateVariableAliases
was called only by its own test and wiring it in would mean a new public
diagnostic handler; it is removed rather than left dangling.
recordInstanceOverrideValue had no caller in either base or head, and
its comment began mid-sentence. SymbolOverrideFields had no consumers,
and savedTextEligibility is used only inside its module.
The clipboard's NON_VISUAL_TYPES was a hand-copied union of the two sets
behind isFigClipboardVisualType, which had no consumer of its own; the
classifier now serves both and leaves the root export.
FIG_PACKAGE_STATUS reads document-reader, and assertFigPackageReady is
gone: the package reads archives into a SceneGraph rather than telling
callers to use Core.
sceneNodeToKiwi takes its ten optional maps as an options object. That
removes the signature Core's wrapper had to restate, which was the last
clone blocking packages/fig/src from the duplication gate, and the
undefined holes at the clipboard's two call sites.
* refactor(core): share identity allocation between the two .fig writers
The clipboard allocated variable, mode and shared-style GUIDs its own
way while the document exporter did the same work in assignVariableGuids
and appendInternalResources. The two already disagreed: the exporter
reuses an id that is already GUID-shaped and dedupes against node source
GUIDs, the clipboard always minted a fresh sessionID 1. Both now call
one pair of helpers in variable-export.ts, so a change to how a document
names its resources reaches the clipboard too.
* refactor(fig): name the values that were spelled out in several places
exportSizing existed to name the HUG ternary but the inline layout
branch still wrote it out. The winding-rule conversions become
toKiwiWindingRule and fromKiwiWindingRule rather than the same ternary
three times and its inverse once. sameId duplicated sameGuid. The style
reference field list existed twice, and one site built a GUID string by
hand instead of calling guidToString. The opacity percent-to-unit factor
and the alias-or-expression test each have a name now.
fig.kiwi declares parameterConsumptionMap as a VariableDataMap and
PropRefValue as a variable value, but the codec typed neither, so four
call sites cast. Typing them in kiwi removes the casts, and the merge
that spread two maps now builds the only field the message has. Schema
coverage counts one more modeled field and one fewer raw-preserved.
* refactor(fig): require the index instead of rebuilding it behind a default
createScopedReader is private and always receives the shared state, and
the closure, component planning and property inheritance always get an
index from it; the optional parameters existed only so two tests could
omit them, and each hid a second full pass over every record. They are
required now, and the tests build an index the way production does.
materializeReader returned a fresh object that dropped definitionTypes,
so the first loadPage after createFigDocumentSession reseeded the cache
it was meant to reuse; it returns the state it was given.
The shared style reference shape is a named type built with the rest of
the export context rather than written inline twice and filled lazily
inside a getter, and the population client derives its two responses
from FigSessionResponse instead of restating one and casting to it.
* refactor(fig): give materializeInstance named options
Three of its seven parameters were defaulted maps that call sites passed
unnamed, so a call read as a list of empty collections. They become an
options object, matching how InterpretInstanceOptions is passed in the
same folder.
That change also caught a latent hazard: an empty array satisfies an
all-optional interface structurally, so a call site left on the old
positional form type-checked while silently dropping its source-child
map. Converting the remaining call sites fixed a component sync test
that had started failing for exactly that reason.
The DOCUMENT/VARIABLE guard is one assertion function rather than two
copies, and it narrows the node type for the creation that follows.
* refactor: group the prefixed siblings this PR left behind
instance-overrides kept layout-scale, text-scale, interpret-bindings and
variable-bindings as prefixed siblings while the same PR introduced
scene-graph/src/{scaling,variables}/. They become scale/{layout,text}
and bindings/{properties,variables}. The empty derived-symbol-data
folder is gone now that it holds one file.
STRING_BINDING_FIELDS and BOOLEAN_BINDING_FIELDS stayed in variables.ts
after NUMERIC_FIELDS moved to variables/fields.ts; all three live
together.
* docs(fig): describe the reader as it is, not as a replacement
The README, document-sessions, validation notes and several comments
still framed the work as pending: an old reader to delete, a migration
to finish, variables and lazy loading not yet integrated. All of that
landed. Error messages and a worker adapter that called themselves
"replacement reader" and "format-neutral" say what they are.
Comments that described the wrong function are reattached: the root
layer note belonged to resolveRoot rather than bindingHistory, the
expand note was duplicated onto bindRecord, the owner-scope note sat on
pairSourceChildren instead of linkInstanceSourceChildren, sync.ts put
its module summary on setSceneProp, and transfer/history.ts ended with
an orphan.
The visual oracle's interpret-instance and compare interpreted-document
are citty subcommands like the rest, its SCREAMING-CASE note folds into
packages/fig/docs/validation.md without the benchmark observation, and
its two tests mirror the source tree using the package alias.
* docs(fig): keep Figma observation records out of the fixture tree
Ten JSON records, twelve notes and a screenshot under tests/fixtures had
no code consumer: they are what Figma reported for a given document,
cited by packages/fig/docs. They move to packages/fig/docs/observations
beside the prose that reads them. The three JSON files tests do load,
and the eight screenshots the raster comparisons load, stay where the
tests expect them.
Fixture READMEs follow their fixtures: the gold layout and shared scale
notes to tests/engine/io/fig/instance, the export contract note to
tests/engine/io/fig/export. Numbers fused to the words before them are
separated throughout the notes.
Path failures assert the diagnostic reason through one helper rather
than matching 'found 0' or a full sentence, which is the pattern
materialize.test.ts already used.
* refactor(core): name the reader state module for what it owns
session/recovery.ts holds the per-graph reader state and, with it, page
population, diagnostics and export population as well as recovery. The
functions cannot move out without exporting that state map, so the file
takes an accurate name instead, and the state type follows.
io/formats/fig/index.ts keeps its aliased re-export: the relative path
is three levels up, which no-deep-parent-relative-imports rejects.
* chore: adopt the js-base64 rule master added
* test: move the new tests to the homes master's gate requires
#790 added check:test-homes: a new test under tests/engine is rejected,
and the baseline of existing ones shrinks. This branch had added 46.
Their owner is whichever package the test's subject lives in, not the
directory the old shard map implies. Forty test Core's writer, editor or
reader session and move to packages/core/tests, which gains the test
tsconfig and scripts the other packages already have; six test Fig alone
and move to packages/fig/tests. verifier-contracts covers the roundtrip
helpers that eight grandfathered engine tests share, so it stays beside
them and joins the baseline.
Package tests no longer reach outside their package for support: each
has local assert, guid, fixture and nested-binding helpers, and shared
archives under tests/fixtures are read through a helper path rather than
imported as modules across the root. interpretComponent,
materializeComponentClosure and the source-children helpers are public,
because tests outside Fig legitimately need them.
The steiger owner for #core/ and #fig/ is the package rather than its
src, since a package's own tests mirror the source tree and would
otherwise drill through ../../src.
* test: mirror each package's source tree in its test tree
The relocated tests kept their tests/engine directory names, which do
not match the packages they landed in: figma/api against src/figma-api,
render/canvas against src/canvas, io/fig against src/io/formats/fig, and
a fig tests/io and tests/text with no counterpart in that package. Each
now mirrors its source domain.
Two had no home in the package they were put in. The derived-text layout
invalidation test only exercises Scene Graph, so it moves there, and the
transfer plan test spans Scene Graph and Fig with neither owning it, so
it becomes the first tests/integration spec, which is what that
directory is for.
tests/AGENTS.md named a baseline path the tools reorganization moved,
and packages/fig/AGENTS.md now records its own test alias.
* fix(fig): open a file whose swap names a layer its component lost
Preline UI's `_header/navbar` keeps a swap addressing 4473:100430, a
node the archive no longer contains, while the replacement it names is
still there. Figma opens that file and so did the previous importer;
this reader refused it.
The rule was written for a swap whose replacement is missing, which
nothing can resolve, but the code threw for any unresolved swap. A path
that matches no record is a record Figma kept after deleting the layer
it named, which is the case the property and assignment diagnostics
already cover. A path that matches more than one record is a wrong
address rather than a stale one and still fails.
* fix(fig): address an override through the variant that holds its layer
An instance path names a layer by the identity it had in the variant the
override was written against. Switching variants keeps the override in
Figma, so a segment that names no layer of the variant an occurrence
expands now addresses the layer at the same position there, when the two
agree on type and name.
Resolution reports the path it took, so a claim recorded after a
translated segment stays addressable when the instance materializes.
Each component set's addressable layers are indexed once on first use
rather than rescanning every sibling variant per segment.
* fix(fig): read text bound to a string variable
Figma stores a bound layer's resolved characters, but an instance
override carries the binding alone, and a literal override of a bound
layer is retired rather than applied. Reading neither left the badge on
Preline's navbar showing its component's own text where Figma shows the
variable's value, and the input placeholder showing a literal override
Figma ignores.
Text joins font family as a bindable string field, the reader records a
TEXT_DATA alias like any other binding, and a post-pass resolves it once
hierarchy and modes exist, next to the paint bindings it mirrors.
Resolving after property claims is what makes a binding win over a
literal, the way Figma retires the override.
Validated by reopening an exported file in Figma: the collection, the
string variable, and the binding on both the component and its instance
survive the round trip.
* fix(fig): take a bound paint's transparency from its variable
A solid fill draws at its paint opacity, not its colour's alpha, so a
colour variable carrying transparency has to supply that opacity.
Resolving the binding into the colour alone left a translucent token
applied twice on Preline's navbar links, and left a Divider at the
opacity of an override the binding supersedes.
The variable now owns the whole colour: its alpha becomes the paint's
opacity and the colour keeps none of its own.
* test(tools): compare paint in the interpreted-document oracle
The oracle checked type, name, visibility, text, main component and box,
so every fill and stroke a reader produced went unchecked. A wrong fill
transparency on Preline's navbar passed it.
Paints are captured on both sides as the alpha drawing actually uses,
which is the paint's opacity for a solid, and reported as visible-paint
or hidden-paint like geometry. A Scene Graph stroke is always solid, so
it is encoded as one rather than through a type it does not carry.
* perf(fig): synchronise a component once per page load, not once per instance
Materializing an instance into an open document re-synchronised every
instance of its component, and synchronising walks each one's subtree.
A page that places a component many times therefore paid that walk once
per placement. Opening Preline's CMS page ran 954 synchronisations over
39225 instances for the 954 it placed.
Components are collected while the page is built and synchronised once
each afterwards: 31 calls over 1283 instances, and the page loads in
3.9s rather than 11.6s. The resulting graph is unchanged, by digest over
every node's geometry, text, paint, bindings and override keys for that
page and for a second page loaded on top of it.
* Revert "fix(fig): address an override through the variant that holds its layer"
This reverts commit fcdc7660f.
Figma does not carry an override onto the corresponding layer of another
variant, so translating a segment that way applies overrides it drops.
On Preline's Alerts frame the translation raises semantic differences
against live Figma from 2 to 54: 127 buttons read their own label where
Figma reads the component's. It fixed nothing visible — the five text
differences it was written for turned out to be string variable
bindings, fixed separately — so it only ever added wrong overrides.
* docs(fig): restore the guide rules the master merges dropped
Splitting the root guide into nested ones lost three rules this branch
had added, and left the fig guide claiming clipboard records are
converted to a SceneGraph in `@open-pencil/fig/clipboard`, which is now
`materializeFigFragment` driven from Core.
Records what the reader cannot do as well: a string binding resolves
once at read time, so text bound to a variable goes stale when the
variable or the node's mode changes, unlike a numeric or colour one.
Groups the four `*-bindings` siblings under `document/bindings/`, the
convention the branch already applied to `instance-overrides/bindings/`.
* perf(fig): copy archive records directly instead of structurally
Every expanded record is deep-copied so an occurrence shares no mutable
data with the archive, a contract two tests state. `structuredClone`
was a third of the time spent opening a page, and records are plain
Kiwi data, so copying them field by field is several times quicker —
43944 records of Preline UI clone identically either way, 218ms against
26ms. Byte buffers and anything else that is not an object literal keep
the structured algorithm.
Preline's CMS page now loads in 2.8s rather than 5.6s, and with the
per-component synchronisation fix in 0d1854a3a, 11.6s before either.
* test(tools): compare a reader's whole output, not one frame
`compare interpreted-document` checks one frame against live Figma. A
rule can leave that frame untouched and still change pages it does not
cover: addressing an override through a sibling variant reported no
difference on the frame under test while rewriting 127 button labels
elsewhere, and was reverted only after a whole-document comparison
found them.
`compare digest` captures every page a reader produces and diffs it
against an earlier capture, reusing the same node capture and
difference categories, so a before-and-after needs no Figma. Replaying
the reverted change against a baseline reports 110 semantic
differences. Unresolved-override counts are reported beside the nodes,
since a reader change usually moves those too.
* feat: preview streamed JSX on the canvas
Project incomplete JSX into isolated scene graphs and disposable pictures without mutating the document or adding intermediate undo entries. Share placement with final rendering and cover lifecycle and placement parity with AI SDK mocks and visual tests.
* test: require partial input for unfinished coordinates
Assert the complete partial object so rejecting the entire input cannot satisfy the truncated-exponent regression test. Addresses CodeRabbit's review finding on #692.
* feat(ai): keep a chat run on its page across page switches
Page switches go through the editor's preparation flow, and the chat panel treated every preparation as a document change: it dropped its Chat and reloaded history, detaching the panel from a reply still in progress. The panel now keeps the live chat unless the tab or the conversation changes.
AI tools also followed the page on screen, so a user browsing mid-run sent the next edits elsewhere, and the agent's own switch_page affected only one call. A run now pins the page where the message started; switch_page moves the run and the user's view, and streamed previews stay attached to the run's page, which the renderer draws only while that page is on screen.
Page snapshots now restore the page they were taken of, so undoing an AI edit works while another page is visible.
* refactor(core): share picture recording and export preparation with previews
Preview recording reimplemented three pieces Core already had: world-bounds picture recording (also duplicated by render chunks and the retained backing), font and layout preparation (prepareForExport), and page subgraph extraction. Extract recordWorldPicture and withWorldViewport for all three recorders, reuse prepareForExport, and add extractPageContext and findPageChildId next to the other subgraph helpers instead of editing a cloned graph's nodes.
prepareForExport also kept the shared layout text measurer overridden across an await, so a concurrent layout could measure with the export renderer. withTextMeasurer scopes the override to the synchronous layout.
* fix(design-jsx): inline nested fragments in streamed previews
The streaming projection kept a nested fragment as an empty-type node, which rendered trees inline, so a preview of <Frame><>…</></Frame> failed with 'Unknown element: <>'.
* refactor(ai): schedule previews and gate test streams with VueUse
The preview controller hand-rolled a trailing timer and abort-listener cleanup, and the test stream gate a promise resolver and listener set. Use useDebounceFn with maxWait (a lone delta still flushes, unlike useThrottleFn with leading off), useEventListener, and until(). Share the mock token usage between chat tests.
* fix(ai): keep previews alive through document edits and slow builds
Document edits finished every preview call, and onInputStart never restarts one, so a render call committing while a second was still streaming ended the second call's preview for good. Edits now invalidate: drop the shown artifact and rebuild on the new document.
A build that finished after another delta arrived was discarded, so a steady stream that outpaced staging and recording never showed a preview. Show it, then render the newer revision.
* docs(changelog): separate the Fixed heading from its entries
Add the blank line markdownlint (MD022) expects after the heading, and drop the one that split the Fixed list in two.
* feat(cli): export Storybook stories beside many documents
Accept several documents, or a quoted glob such as 'src/**/*.pen', and add --beside to write each document's stories, design images, and manifest into the document's own folder, next to the component's code. Documents export one after another, since documents in one folder share its manifest; a failed document is reported and the rest still export. --watch covers every matched document through one queue. Several documents need --beside or --output, and --page takes a single document.
Refs #727
* fix(cli): resolve Storybook export documents by existence, not glob syntax
Deciding between a path and a pattern by looking for glob characters missed
extglobs, so 'src/+(a|b).pen' was opened as a literal filename, and it flagged
an escaped star, so a file genuinely named that way went to the matcher. The
character list also could not agree with Node's matcher: is-glob rejects a
bare '?', picomatch accepts a parenthesised directory name.
An existing path is now that file, and everything else goes to glob(), which
matches a plain path to itself and expands every pattern it supports.

* build(core): import Markdown with unplugin-raw
Core inlined ?raw imports with a hand-written Rolldown plugin that also turned plain .md imports into strings, which nothing in Core uses. unplugin-raw already does this for the Vue SDK and design-jsx; use it here too and drop the unused *.md module declaration.
* refactor(pen): use the scene-graph color parser
pen/src/color.ts duplicated parseColor from @open-pencil/scene-graph/color line for line. Import it instead, which also drops pen's direct culori dependency.
* fix(figma-api): validate effects like Figma
The effects setter stored whatever a script passed, so scripts that Figma rejects ran here and malformed effects reached rendering and .fig export. Validate against Figma's effect shapes with Valibot, recorded from live Figma: strict objects, required shadow fields, radius >= 0, RGBA channels within 0..1, and no shadow fields on blurs. The getter now returns Figma's shape so node.effects = node.effects keeps working.
Closes#786
* fix(figma-api): reject infinite numbers in effects
Figma rejects Infinity in every effect number ("Number must be finite"), but v.number() accepts it, so infinite radii, offsets, and spreads reached the scene graph.
* fix(figma-api): store PASS_THROUGH shadow blend as NORMAL
PASS_THROUGH is a layer blend mode. Live Figma accepts it on drop and inner shadows but reads NORMAL back, so do the same instead of storing it.
* refactor(design-jsx): extract design JSX into its own package
Design JSX elements, helpers, schema, reference, and JSX export only need
the scene graph, yet lived in Core, so every consumer of the authoring API
pulled in the renderer, layout, and file formats.
@open-pencil/design-jsx now owns them and depends only on scene-graph. The
renderer takes icon lookup, SVG conversion, vector creation, and layout as
DesignJSXServices; Core binds its own and exports the bound renderJSX and
renderTree from @open-pencil/core/design-jsx.
* feat(design-jsx): export the JSX runtime for TSX authoring
The package already had a JSX runtime, but nothing exported it, so design
trees could only be written as function calls or JSX strings. Export
`./jsx-runtime` and `./jsx-dev-runtime` so `jsxImportSource` works, and make
`Fragment` produce the same empty-type node as `<>` in `renderJSX` strings.
* fix(design-jsx): render fragments nested in other elements
A fragment builds a node with an empty type, which only renderJSX expanded, and only at the root. Nested fragments and fragments passed to renderTree failed with 'Unknown element: <>'. Inline fragment children when trees are built, and share root expansion between renderTree and renderJSX.
parameterConsumptionMap is a VariableDataMap like variableConsumptionMap
beside it, and a variable value can carry PropRefValue or Expression;
the schema declares all three but the codec typed none, so every reader
cast to reach them. Schema coverage counts one more modeled field and
one fewer raw-preserved.
The describe tool judges text contrast by the WCAG 2 ratio (4.5:1, or 3:1 for large text) instead of a dark-on-dark luminance heuristic, and reports the ratio and threshold. It measures translucent and faded text as drawn, treats text as large only when the base style and every style run are, and skips variable-bound colors. contrastRatio() and compositeOver() now live in @open-pencil/scene-graph/color and are shared with the color-contrast lint rule and canvas labels. Fixes#735.
The 54 editor engine tests move to packages/core/tests/editor with their helpers, importing Core's public subpaths or source modules relatively. The package gains test and typecheck scripts; the first type check fixed nullable lookups, stale imports, and renderer doubles, and graph events now declare the GraphEventRenderer surface they invalidate. The engine baseline drops to 534 files.
* fix(design-jsx): accept blur in effect helpers and warn about unknown options
dropShadow({ blur: 12 }) silently used the default radius, although the shadow shorthand and the blur prop both call that value the blur, and any misspelled option was dropped without a word. The shadow and blur helpers now take blur as the radius, and renderJSX reports any other option they ignore, next to the existing unsupported-prop warnings.
Fixes#736
* refactor(design-jsx): check options for every paint and effect helper
The option check covered only effect helpers, and its key lists repeated
the option types by hand, so a new option could turn into a false
warning. One wrapper in `design-jsx/helpers.ts` now checks every paint
and effect helper that evaluated JSX can call, with key lists typed
against their option interfaces. Only plain objects are checked, and
repeated warnings are collapsed once. The authoring reference documents
the `blur` alias and the warnings.
* docs(design-jsx): scope helper option warnings to rendered JSX
* fix(design-jsx): name effect radius as Figma does and hint at it for blur
Accepting both `radius` and `blur` gave effect helpers two names for one
value, and when both were set `blur` was dropped without a warning.
Figma's effects only have `radius`, so the helpers take `radius` alone
and `blur` now warns with a pointer to it. The default radius is named
once instead of repeated.

* refactor(dom-css): group sources into import, export, and runtime
dom-css kept both conversion directions in one flat folder: HTML and CSS
import next to SceneGraph export, a JSX runtime next to the Tailwind JSX
printer, and CSS parsing and formatting in one file.
Sources now live in `import/`, `export/`, and `runtime/`, with the CSS
value helpers split by direction and `export/index.ts` as the `./export`
entry. Tests mirror the new folders. Public entry points are unchanged.
* docs(dom-css): add a package guide for the import, export, and runtime layout
dom-css had no AGENTS.md. The guide records the source layout, the
scene-graph-only dependency, the browser-safe `./export` entry, printed
code generation, and Base64 validation for imported documents, and the
root map links to it.
instance.swapComponent(component) points an instance at another component, as in Figma, through the graph's shared swap that the editor's variant picker uses. It asserts editability, so an instance inside a read-only library definition cannot be swapped, and joins the instance surface check against @figma/plugin-typings.
Groups and boolean operations made through the plugin API, and so through the AI and MCP group_nodes and boolean_* tools, take the box of what they contain instead of a default 100×100 box or the first operand's box. The box comes from getAxisAlignedBoundsInParent() in Scene Graph, measured in the parent's own axes so rotated or flipped parents work, and the editor's group, frame, auto-layout, and boolean commands share it so the UI and the API agree. Refs #738.
instance.detachInstance() turns an instance into a frame that keeps its content, as in Figma, from scripts run through eval. It reuses the graph's shared detach implementation, asserts editability like the proxy's other mutations, and joins the instance surface check against @figma/plugin-typings.
Scripts written for Figma's dynamic-page mode can call figma.getNodeByIdAsync() and instance.getMainComponentAsync(); both resolve to the same nodes as their synchronous forms. getMainComponentAsync joins the instance surface type check against @figma/plugin-typings.
Tools live under tools/<role>/<domain> (checks, generate, release, ci, dev), every tool is a workspace named @open-pencil/<domain>-tools, a shared tools/tsconfig.json backs the new check:tools gate that fixed 55 latent type errors, test:tools runs through bun --filter, the placement check is its own checks/test-homes package, and every tool resolves the repository through resolveWorkspaceRoot. Bun, Node, and mdast types live in a tools-root workspace so they never reach the app program.
Scene Graph unit tests move to packages/scene-graph/tests with a package-local assert helper and test type-checking; five Core- and fig-owned tests move to their owners' engine homes. check:test-homes rejects any new test under tests/engine against a reviewed baseline so the migration debt only shrinks.
A reparented node keeps its drawn position, rotation, and flips: translation-only parent chains shift x/y by the parents' origin difference, and any other chain decomposes the node's world matrix against the new parent through localTransformFromWorld() in coordinate.ts. Fixes#737.
* feat(cli): export components as Storybook stories
Add `openpencil export -f storybook`, which writes one CSF3 `.stories.ts`
file per component set or component. Each variant becomes a story and the
variant properties become select controls, so the story renders the matching
variant; an unknown combination throws instead of showing another variant.
Stories embed the existing inline-style HTML projection, so consumers need no
OpenPencil runtime. `--framework react|vue|html` only changes the render
wrapper and the Meta/StoryObj import. When the document sits under the current
directory, stories carry an `openpencil://` design link for
@storybook/addon-designs.
Refs #727
* fix(pen): size auto-width text from its content on import
Text without a width in an auto-layout parent was imported 10000px wide, a placeholder the app's text measurer replaces. Headless layout keeps stored sizes, so CLI HTML and Storybook exports stretched hugging frames to over 10000px. Import the width as 0 so the importer's existing text-length estimate applies, and headless layout estimates the rest.
* feat(app): follow layer links to other pages
openpencil:// and web ?node= links only searched the current page, so a Storybook story linking to a component on another page reported it missing. When the current page has no match, load the other pages without showing them and switch to the first that carries the name.
* feat(cli): add design images and watch mode to Storybook export
Each story now links to its own variant when the layer name is unique, and carries a 2x PNG of the variant for @storybook/addon-designs, imported so Vite bundles it. --watch re-exports on every save. Re-exports replace the stories a previous export of the same document generated, including those of deleted components, and refuse to overwrite hand-written stories or another document's.
Refs #727
* fix(cli): reference Storybook design images without ambient PNG types
Import design images with new URL(..., import.meta.url) instead of an import declaration, so consumers need no vite/client types to typecheck the stories. Document that exports should run from the same directory.
* fix(app): search other pages for a link without cancelling page switches
The cross-page layer search prepared each page with preparePage, which advances the page-switch generation, so a page switch the user had in progress could be dropped, and every searched page paid for fonts and layout. Add loadPageNodes, which populates a page's layers through the same worker path without touching the switch generation, and report a failed search as an error instead of a missing layer.
* fix(pen): never import width-less text zero wide
Text without a width now imports at width 0 and relies on the importer's text-length estimate, which skipped single-glyph text. Estimate zero-width text of any length.
* fix(cli): harden Storybook export ownership, titles, and links
- A --page export replaces only its own stories, and names files as a full export does, so it cannot delete or overwrite other pages' stories.
- Same-named components on a page get distinct titles, so Storybook story ids do not collide.
- Read the generated header through CRLF line endings, and refuse a source containing a line break, which would end the header comment and start code.
- Link a story only to a layer name no other layer carries.
- Document the --page default for Storybook export.
Refs #727
* fix(app): let a page switch overtake a link's layer search
A link search that loads other pages could resume after the user started switching pages and move them to the matching page. Expose pageSwitchCount, which advances whenever a page switch starts, and abandon the search when it changes. An overtaken search reports neither a match nor a missing layer.
* fix(pen): estimate only omitted text widths
Estimate a width-less text node's width when it is imported, instead of estimating every zero-width text node afterwards, so an explicit width of 0 is kept.
* fix(cli): track Storybook story ownership by document path and page
- Identify the document by its path relative to the output directory rather than a basename or cwd-relative path, so same-named documents do not share stories and the export no longer depends on the working directory.
- Record the page in each story's header; a --page export replaces all of that page's stories and asks for a full export when renumbered file names land on another page's.
- Check every target, including design images, before removing anything, and refuse to overwrite files this export does not own.
- Quote the header fields as JSON with U+2028/U+2029 escaped, so any path stays inside the comment, instead of refusing line breaks.
- Deduplicate titles by Storybook id, which ignores case and punctuation.
Refs #727
* fix(app): focus a searched page only after its switch committed
A page switch the user starts while the link search's own switch is pending can keep that switch from committing. Check that the search's switch was the only one and landed on its page before focusing; otherwise report the search as superseded.
* fix(pen): keep empty text without a width at zero
* fix(cli): remove only the design images a Storybook export generated
Replacing a story removed its whole .design folder, including files someone else put there. Read the images each owned story references, remove just those, and remove a .design folder only once it is empty.
Refs #727
* test(app): cover a page switch still pending during a link search
The previous test committed the overtaking switch, so the page check alone caught it. Advance the switch count without committing, so the test fails without the count check.
* fix(cli): stage Storybook exports and refuse linked design folders
- Write every file to a staging folder inside the output before removing the previous export, then move them into place, so a failed write no longer leaves the export half replaced.
- Refuse a .design path that is not a real folder, such as a symbolic link, before removing or writing images through it, so an export cannot reach outside the output directory.
Refs #727
* refactor(dom-css): print Storybook stories from a parsed template
Story modules were assembled from string fragments, so quoting and
layout were an implicit contract: the CLI found design images with a
regex that only matched double-quoted `new URL("…")` paths.
A story module is now one TypeScript template, parsed once with acorn
and its TypeScript plugin. Data is filled into `$placeholder` nodes and
the module is printed with esrap, which owns quoting and escaping. The
CLI reads referenced design images back through `storyImagePaths()`
instead of matching text. Tests import generated modules and assert
values rather than formatting.
* refactor(storybook): track generated files in a manifest
The export recovered which files it owned by parsing its own output: a
header regex over JSON-quoted strings, line-separator escaping, CRLF
handling, an AST walk for design images, and a path regex in the CLI.
A `.openpencil-stories.json` manifest now records the document and page
behind each generated file. The CLI validates it with Valibot, including
that every listed path stays inside the output folder, and the story
header is a plain note. Story ids use a copy of Storybook's `sanitize`,
tested against the installed Storybook; the previous rule treated `A§B`
and `A-B` as the same story. Export names use es-toolkit's `pascalCase`.
The CLI export command moves into `commands/export/`, dom-css splits
grouping and naming out of the Storybook exporter, and the CLI takes the
framework list from dom-css.
* fix(pen): keep explicit narrow text widths
A post-import pass widened every multi-character text narrower than two
font sizes, including widths the `.pen` file set on purpose, such as
`width: 0`. Omitted widths are now estimated when the text node is
created, so the pass only overrode explicit widths and is removed.
