fix(fig): write text glyphs from the layout the renderer draws (#928)
* fix(fig): write text glyphs from the layout the renderer draws

Text without saved glyphs was written to .fig with outlines from a
character-by-character fallback: one unwrapped line at y = lineHeight,
no alignment, advances in pixels. Figma lays saved text out from that
data, so every wrapped OpenPencil label opened in Figma on one line, and
since saved glyphs now draw before the paragraph, OpenPencil did the same
after a reopen (#914). The Figma clipboard had a second writer with its
own shaping that matched outlines to characters by index.

One builder in @open-pencil/fig now writes derivedTextData for both. It
keeps glyphs a layer already has and otherwise asks the export runtime to
shape the text. Core shapes with the paragraph the renderer draws, so
lines, alignment, and baselines match, and takes each outline from the
glyph ID CanvasKit chose, so ligatures and contextual forms keep their
shapes. CanvasKit does not say which font drew a run, so outlines are
written only when the run's own font covers it; otherwise the layout is
written without outlines and readers lay the text out themselves.
Advances are in em units and the character offset map has one entry per
character, as in Figma's files.

The reader drops glyphs the earlier fallback wrote, recognised by its
offset map one entry longer than the text with every glyph on the one
written baseline, and any glyph set with a missing outline.

* fix(scene-graph): reflow resized text instead of stretching its glyphs

Resizing scaled a text layer's saved glyphs into the new box. That suits
path text, whose glyphs follow its path, but flat text reflows, and with
saved glyphs drawn before the paragraph a resized Figma text layer was
drawn stretched. Scale glyphs only for path text, including baked path
text that kept only rotated glyphs, and let the width change drop the
rest.

* docs(fig): describe how derived text is written

Figma draws saved text from derivedTextData even when it has the font, so the export docs record which glyphs the shared writer keeps, shapes, or leaves without outlines, and the units it writes. The README names the runtime service by what it now does.

* fix(fig): write text without glyphs when shaping fails

Glyphs are derived data, so a shaper error must not fail the .fig save or Figma clipboard copy that writes them. The builder now writes the layer without glyphs and logs a warning; the clipboard used to swallow the error silently, which hid a font-provider mismatch.

feat(collab)!: sync layer trees as a CRDT and open each room in its own tab (#902)
* fix: stop ancestor walks from hanging on a parent cycle

A collaborator's concurrent reparent can leave two layers as each other's
parent. isDescendant, the design check's pageOf, and component sync walked
parentId without a bound, so applying such a change froze the editor.

Add SceneGraph.closest(), a bounded nearest-ancestor lookup, and use it for
these walks so bad data ends the walk instead of the tab.

* fix(collab): sync layer moves without parent cycles or stale child lists

Remote changes assigned each layer's synced parentId and childIds as plain
properties. Two peers moving layers into each other made them each other's
parent, a moved layer stayed listed under its old parent, reorders never
synced, and concurrent additions ended up in different orders or missing
from the parent's list.

Apply the tree after a change's properties: move layers to their synced
parents, skip a move that would make a layer its own ancestor and write the
layer's current parent and position back so every peer settles on it, and
derive each touched parent's childIds from its synced order followed by
unlisted children by id. Locally, a parent's child list syncs once after
each edit that adds, removes, moves, or reorders its children.

Fixes #888
Fixes #889

* refactor(scene-graph)!: move sibling order keys to scene-graph

Collaboration needs the same fractional keys as .fig export to order
siblings, and the app must not depend on @open-pencil/fig for them. Move
fractionalPosition, orderKeyBetween, and siblingOrderKeys to
@open-pencil/scene-graph/order-keys.

orderKeyBetween now always returns a key: when no printable key fits it
returns one above lo, which hasOrderKeyBetween detects, so callers no
longer branch on null. It takes an optional suffix, and siblingOrderKeys
can request one per key, so two peers inserting at one spot get distinct
keys. .fig export keeps its keys.

* fix(scene-graph): report instance child reorders as graph events

Instance sync sorted an instance's children in place, so nothing that
listens to graph events saw the new order; in a shared room the order
never reached other peers. Move each child that changes position with
insertChildAt, which reports the reorder.

* feat(collab): resolve the layer tree from each layer's parent history

Add a pure LayerTree for the shared document: each layer records every
parent it was moved under with a move counter and an order key. A layer
sits under its newest parent, ties broken by parent id; when concurrent
moves close a loop, the latest move in the loop falls back to the
layer's next entry until none is left, and a layer no parent can take
goes to its page (Evan Wallace's mutable tree hierarchy CRDT).

The result depends only on the entries, and resolution revisits only
changed, orphaned, and displaced layers. Seeded random runs check that
peers converge and that the incremental result matches a full one.

* fix(collab): sync layer moves as parent history and order keys

Each layer's shared map now records every parent it was moved under with
a move counter from a document-wide Lamport clock, and its order key
among siblings, instead of parentId and childIds. Every peer derives
parentId and childIds from these with LayerTree, so concurrent moves,
reorders, and additions merge, a loop from concurrent moves undoes its
latest move, and a layer whose new parent was deleted meanwhile returns
to its previous one.

A local edit's graph events are written once after the edit, in one
transaction. It records a parent entry for each layer whose parent
changed, a new entry for displaced layers on the touched paths so a move cannot pull
them back, and keys between the moved layers' neighbours with a random
suffix, so concurrent inserts at one spot get distinct keys. Remote
changes find their layers through each event's path, resolve only what
they touch, and move and sort layers through insertChildAt.

This replaces the childIds merge and the write-back of rejected moves:
a rejected move now resolves the same way on every peer from the shared
history, so nothing needs to be written back.

* feat(collab)!: convert saved rooms and keep mismatched builds apart

A room saved by an earlier build records parentId and childIds. When a
change brings in such layers, from this browser's storage or a peer,
convert them in one transaction: each layer's synced parent becomes its
only entry with counter 0, its position in the parent's synced childIds
becomes an order key, and the old fields go. The result depends only on
the document, so two peers converting at once write the same values,
and converting again writes nothing. The document's meta map records
treeFormat 2.

Builds that record the tree differently would corrupt each other's
rooms, so the collaboration namespace becomes openpencil/2 for Trystero
and the test relay alike, and each peer publishes its treeFormat in
awareness for future version messages.

* fix(collab): send a layer whose parents were all deleted back to its own page

Each layer's shared map records the page it was last placed on, and the
layers under a frame moved to another page are re-recorded. A layer whose
parent chain was deleted goes back to that page, falling back to the first
page only when the recorded one is gone. Saved rooms record pages when
they are converted.

* fix(collab): keep one root per room when peers edit their own documents

Joining a room keeps the joiner's earlier document in its graph, and an
undo or an edit made before the room arrived could still reach it. That
edit shared the joiner's root, every peer adopted it, and the room's
pages disappeared.

The room now records its root as claims in meta, each with the time it
was made, and every peer follows the earliest. Sharing claims the room,
and so does the first edit in a room nobody has shared, which now shares
the whole document as Share does. A peer shares only layers under the
room's root. Converted rooms claim the root with the most children.

Move counters must also be safe integers, so an oversized counter from
another peer cannot stop the move clock from advancing.

* fix(collab): rank root claims by how they were made, not by clocks

Root claims carried the claiming peer's wall-clock time, so a guest whose
clock ran behind the sharer's could still win the room with an edit made
before the room reached them. A claim now records whether it came from
Share or a converted room, or from the first edit in an unshared room;
a shared root outranks an edited one, and the lower id breaks a tie.
A claim also replaces an invalid value already stored for its root.

* fix(collab): keep every root claim through concurrent writes

A root claim was one key per root holding its kind, so two peers claiming
the same root by Share and by an edit at once kept only one of the two
values, and the shared claim could be lost. Each kind of claim on a root
is now its own key. Converting a saved room also claims its root unless
a shared claim exists, so a guest's earlier edited claim no longer keeps
the converted room from outranking it.

* fix(collab): mint layer IDs under a session of each editor window

Every editor window started its IDs at 0:1 from the same counter, so two
people adding layers to a shared room at once could mint the same IDs,
and one person's layers replaced the other's in the room. A joiner's
starting page also took the sharer's page ID and stayed in their list.

SceneGraph's default IDs now carry a session set with setIdSession, as
in Figma's sessionID:localID GUIDs. The editor picks a random 32-bit
session at startup, as Yjs does for each document's clientID; headless
tools keep session 0, so the CLI and MCP server give a file's layers the
same IDs on every run.

* fix(collab): let only Share set a room's root

A guest's first edit in a room whose contents had not arrived claimed
the room and wrote the guest's whole open document into it, images
included, and adopting the sharer's root later only hid it. Every room
starts with someone sharing a document, so a guest has nothing to claim:
only Share, or converting a saved room, now sets the room's root, as a
single value in meta, and a peer writes nothing until the root is known.

Unbinding a room also writes an edit still waiting to be sent, so a move
or deletion made just before leaving reaches the room.

* feat(collab)!: open each room in a tab of its own

Joining a room bound it to whatever tab was active, so a pasted link
could turn a saved file into the room's document, and a share link first
showed an editable blank document. A room is now a document: joining
always opens it in a new tab, or switches to the tab already showing it,
and only Share puts an existing tab's document into a room.

Every room tab owns its session (src/app/collab/rooms.ts and
session.ts), so several rooms can be live at once and keep syncing in
the background. The collaboration panel, presence, following, and the
/share/<id> address follow the active tab, and a canvas publishes its
cursor and selection only to its own tab's room.

A room tab derives its state: joining while its saved copy loads, then
waiting, with an explanation, while nobody who has the file is online;
live with others, or alone on this device's copy. Until the document
arrives the room's screen replaces the editor. Reloading a share link
rejoins it; leaving a room you joined keeps its file as a local unsaved
copy. "Connected" now means another peer answered. Pasted links and IDs
are normalised and validated, and invalid ones say so.

People join right away under a generated name such as "Teal Fox", with
a hint to set one; the one app-wide name is set in the share panel or
in Settings. On a phone, Share copies the room's link instead of making
a new room, and the presence popover shows the room's state.

* feat(desktop): open rooms from openpencil://join links and Home

The desktop app could not receive a share link: links point at the web
app, and openpencil:// only opened files. openpencil://join?room=<id>
now opens the room in a tab of its own. The native parser refuses
anything but a room ID, queues rooms for the frontend through
take_pending_rooms, and a second launch on Windows and Linux forwards
its link through the single-instance handler.

In a browser on a computer, the room's screen and the share panel offer
Open in desktop app, a link the browser hands to the app on click; it
never opens the app by itself. Home gains Join room…, which takes a
pasted room link or ID and opens the room in a new tab.

* feat(collab): set your name on the room screen

The room screen told someone joining under a generated name to set
their name but offered nowhere to do it before the file arrived. It now
has the same name field as the room panel.

* feat(collab): offer the desktop download beside Open in desktop app

A browser on a computer offers a room's openpencil://join link, which
does nothing where the app is not installed. The room screen and panel
now link to the latest release beside it.

* docs: describe joining rooms in the German, Polish, and Russian guides

Bring the translated collaboration pages up to the English one: Share as
the only way into a room, joining in a tab of its own, the waiting
screen, leaving with a local copy, and how layer moves merge. The
English page now names the panel's Leave room button.

* fix(collab): lay out the room screens like the app's empty states

The joining and waiting screens were a left-aligned card with a stray
spinner, a primary Copy link button beside an outline button and a
bare link, and a name field on a screen that lasts seconds. They now use
AppPlaceholder, centred over the tab: a heading, the explanation, the
two hints, secondary Copy link and Leave, a 'You'll appear as' line
whose Change opens a small rename popover, and the desktop handoff on
one muted line. The room panel lines its status dot up with wrapped
text, no longer selects the room link when it opens, and puts the
desktop links and Leave room on one footer line.

* fix(collab): show what a room tab is doing instead of a timed guess

A joined tab said nobody with the file was online five seconds after it
opened, whether or not it had reached the signaling service or met the
people already in the room. Its state now follows what the tab can
observe: connecting until the service answers, looking for people for as
long as that transport takes to introduce everyone, getting the file
from someone who says they have it, waiting when nobody who has it
showed up (naming other guests waiting too), and a can't-connect screen
when the service cannot be reached. Each peer says in its presence
whether it has the room's file.

* fix(collab): list other waiting guests with the explanation

The line naming other guests who are waiting too is information, not an
action, so it follows the hints above the buttons. Peers' hasFile flag
is optional, as older builds do not send it.

* fix(collab): send a canvas's cursor and selection to its tab's room again

Canvases read the editor through a proxy that follows the active tab,
and the room lookup by store never matched it, so pointer moves and
selections stopped reaching the room: collaborators lost each other's
cursors, selections, and page markers. The canvas now looks up its
room by its tab's own store, and its selection listener ends when the
canvas unmounts instead of piling up across tab switches.

* feat(collab): one avatar stack for the toolbar, the mobile pill, and pages

The toolbar, the page list, and the mobile HUD each drew the people in a
room their own way, and the mobile pill read 'Online: 3' in hard-coded
English beside a status dot too small to render. AvatarStack now draws
people overlapping with their agent counts and '+N', and every place
uses it: the toolbar wraps each avatar in its menu or hover card, the
mobile pill shows the room's state dot and the stack with a translated
name, and hovering a page with people on it opens a card with the stack
and who is there, with their agents, to follow. The mobile list is the
shared presence list, so it is translated and can follow agents too.

* docs: note the page hover card and mobile avatars in the changelog

* fix(collab): stop listening to a room once its tab leaves it

A session left its Yjs observers and its awareness listener attached
after dispose, relying on destroy() and the order of teardown not to
touch the tab again. It now removes them explicitly and clears its peer
list. Also fix a missing comma in the Polish collaboration guide.

chore: prefer es-toolkit helpers and lint the mechanical cases (#898)
* chore: prefer es-toolkit helpers and lint the mechanical cases

AGENTS.md now names the es-toolkit helpers to reach for instead of hand-written equivalents, and the exceptions: a single clear native call or a measured hot path. The new open-pencil/prefer-es-toolkit rule rejects filter(Boolean) and Set round trips on arrays, the two cases that need no type information, and the existing 45 sites use compact and uniq. tools/ci/policy runs before dependencies are installed, so the rule is off there.

* refactor: deduplicate diagnostic categories with uniq

* fix: keep es-toolkit out of serialized Playwright callbacks

The codemod rewrote a filter(Boolean) inside a page.evaluate callback, which Playwright runs in the page where the compact import does not exist. The spec filters there again, and the rule now skips callbacks passed to evaluate, $eval, $$eval, evaluateHandle, addInitScript and waitForFunction, and filter calls on iterators from values, keys, entries and matchAll, which compact cannot take.

* test: write the prefer-es-toolkit cases like the other rule tests

Short standalone snippets, as in the base64 and JSON rule tests, instead of a declaration prefix on every case and inline object types.

feat(scene-graph)!: let a SceneGraph take its ID generator (#887)
* feat(scene-graph): let a SceneGraph take its ID generator

The constructor accepts an ID generator, used for the root node and for
nodes, variables, and collections created later; generated IDs skip any
node, variable, collection, or mode ID already in the graph.

Refs #770

Signed-off-by: Marc Went <marc@went.io>

* perf(scene-graph): check mode IDs without allocating per created entity

Generating an ID spread every collection into a new array and scanned it
for each candidate, which runs on every createNode. Check the node,
variable, and collection maps first and walk the modes with an early exit.
An index of mode IDs is not kept because history snapshots, transfer, and
undo replace collection maps and edit modes in place, which would leave it
stale.

* test(scene-graph): cover injected ID generators and collision skipping

* docs: note the SceneGraph ID generator in the changelog

* test(core): keep reopened .fig GUIDs when a sibling is inserted before them

Refs #770

* test(collab): cover concurrent additions, same-property writes, and delete versus edit

Move the synced-store harness to tests/helpers/collab so the new cases
live in tests/app/collab, and let it bind graph events as a collab session
does. The cases edit both peers while disconnected and check the
converged graphs.

Refs #770

* fix(scene-graph): keep a collection's IDs apart and stop on an exhausted generator

createCollection asks for the collection and default mode IDs before
registering either, so a generator repeating a candidate gave both the
same ID. A generator that only returned taken IDs looped forever, even in
the constructor; it now throws after a bounded number of attempts.

* test: require the inserted GUID and a real disconnect in new tests

The GUID test passed even if export dropped the inserted layer, and the
concurrent-edit helper would have tested sequential sync had its peers
not been disconnectable.

* feat(scene-graph): create variable modes through the graph's ID generator

The editor minted added and duplicated modes as mode:<random hex>, so an
injected generator governed every graph entity except modes added after
a collection's first. SceneGraph.createMode mints the ID and adds the
mode; undo and redo replay it with addMode.

* test(core): type the reopened .fig buffer in the GUID test

* refactor(scene-graph)!: share random helpers and one component property ID

randomHex, randomInt, and randomIndex move from @open-pencil/core/random
to @open-pencil/scene-graph/random, so format packages can use them:
design-jsx and the MCP test server dropped private copies. Component
property IDs, written as prop:<random hex> in six places across Core and
design-jsx, come from createComponentPropertyId.

* docs: point the randomness rule at the shared ID and random helpers

refactor: define OpenPencil plugin data in one typed registry (#878)
* fix: validate parsed JSON at untrusted boundaries with Valibot

Clipboard HTML, library revisions from shared storage, MCP and automation
WebSocket messages, the MCP discovery file, sidecar output and AI/MCP tool
arguments were JSON.parse'd and cast to their expected types, so a
malformed payload reached the document or crashed paste. They now go
through v.pipe(v.string(), v.parseJson(), Schema), which reports bad JSON
and a wrong shape as the same validation failure.

The path_set tool rejects an invalid VectorNetwork and shares its parser
with create_vector. The CLI library catalog validates its files and runs
revisions through the same size, identity and content-hash checks as the
app; reading image bytes as index-keyed records also stops them coming
back empty. Hand-rolled typeof readers for plugin data, document metadata,
caches and preferences become schemas with their behaviour preserved, and
readCacheJSON takes a schema for its payload.

open-pencil/no-unvalidated-json-parse rejects type assertions on
JSON.parse results other than `as unknown` in src and packages/*/src.

* refactor: validate parsed JSON in tests and tooling

Extend open-pencil/no-unvalidated-json-parse beyond source: tests, helpers and repo tooling now parse JSON through Valibot schemas instead of asserting a type. The shared fixture reader returns a validated object; its old array annotation never matched the fixtures.

* refactor: define OpenPencil plugin data in one typed registry

Every plugin-data key OpenPencil writes is now a field of OPEN_PENCIL_PLUGIN_DATA in scene-graph, with the Valibot schema that reads it; readPluginData and withPluginData replace per-key constants, JSON.parse and hand-matched pluginId/key filters across fig, core, and vue. Moving OkHCL onto it fixes picking a colour rewriting the layer's other plugin data as OkHCL entries.

fix: export layers and pages that are not on screen in app mode (#877)
* fix(automation): export layers from a page that is not on screen

The app's raster export rendered against the page on screen unless the
caller passed a page, so MCP export_image with ids on any other page, or
with page_id naming another page, failed with "Raster export selection
must stay on a single page". Automation shares one app between clients,
so the page on screen says nothing about what a request means.

Render on the page that holds the requested layers instead. The user's
view and selection stay where they were.

* fix(cli): export the requested page from the running app

`openpencil export --page` never reached the app: `exportViaApp` only
forwarded `--document-id` and `--page-id`, and the app's `export` RPC
exported the given nodes or the selection on screen, ignoring the target
page. `--page` and `--page-id` therefore exported whatever was selected.

The CLI now resolves `--page` to a page ID through `list_documents` and
asks for a page-scoped export. The app answers a page-scoped export with
the layers of the target page, loading a `.fig` page that has not been
shown yet without switching to it.

CLI tests address the package source by `#cli/`, as Core and fig tests
already do, so the alias owner widens to the whole package.

* fix(automation): prepare fonts and layout for a page exported off screen

A page export loaded the layers of a page that had not been shown, but not
its fonts or layout, so text and auto layout could render differently from
the screen. preparePageNodes runs the same font and layout pass as a page
switch, once per page, without switching or superseding a switch.

The CLI export test now writes its own discovery file, so it no longer
replaces or removes the record of an app that is running.

* fix(automation): prepare a .fig page before running a tool on it

A `.fig` opens with only its first page populated; the others get their
layers, fonts and layout when first shown. The automation tool handler built
its FigmaAPI on the target page without loading it, so MCP tools aimed at a
page nobody had opened (`page_id`) saw an empty page: find_nodes found
nothing, export_image reported "No visible nodes to export", and create_shape
added a shape to a page that then held only that shape.

Prepare the target page first with preparePageNodes, as page exports do:
layers, fonts and layout, once per page. The page on screen does not change.

* fix(automation): render explicit export IDs on the page that holds them

Since the visual diff tools, the automation FigmaAPI passes its target page
with every raster export, so export_image with IDs from another page asked to
render them on the target page and failed with "Raster export selection must
stay on a single page". The page now names which layers to export only when no
IDs are given; an ID list is rendered on its own page.

* fix(core): share one off-screen page preparation between concurrent callers

Two concurrent preparePageNodes calls for the same page both populated it
and resolved its fonts, and the font manager's blocked-node set has no
reference count, so the first to finish unblocked text the second was still
resolving. Callers now share the in-flight preparation, which is kept once
it succeeds and retried after a failure.

preparePageNodes also reports whether the page is ready, so a caller can
refuse to run on a page whose document was closed or replaced mid-way
instead of acting on a page with no layers. Its unused options are gone:
one caller's signal cannot cancel a shared preparation.

* fix(automation): prepare the target page once for every command

Preparing an unshown .fig page lived in the page export handler, so explicit
export IDs, export_jsx, eval, tools, and the RPC fallback still saw such a
page as empty. The request dispatcher now prepares the resolved target page
before any page-targeted command, and stops with an error when the page's
document closed while it loaded.

* docs(changelog): fold the off-screen page fixes into one entry

* refactor(automation): rely on the dispatcher to prepare a tool's target page

The request dispatcher now prepares the target page before every
page-targeted command, so the tool handler no longer does it itself. The
tests run tools through the dispatcher, which is where that guarantee lives.

* docs(changelog): drop the tool entry now covered by the off-screen page fix

fix(core): save an unedited worker-opened .fig instead of hanging (#880)
* fix(core): save an unedited worker-opened .fig instead of hanging

Saving a .fig that was opened through the session worker and not edited
yet never finished. The export asks the worker for the original archive,
but the reply listener lived in port1.onmessage, which
registerFigPopulationWorker replaces once the graph arrives. The worker
answered and the reply was dropped, so the save promise never settled.

Listen for archive results with addEventListener so the population
client can own onmessage.

* test(core): drive the session worker open directly in the archive save test

IS_BROWSER is read once at import and Bun shares the module cache, so when another session test loads the reader first, parseFigFile took the main-thread path and the test passed without the fix. Export the worker open from read.ts and call it directly, release the worker afterwards, and drop the global window patch and the uncleared race timer.

feat: model variables as CSS design tokens (#852)
* feat(scene-graph): model variables as CSS tokens

A variable now has a CSS custom property name, a unit, raw CSS expressions
per mode, and each mode a CSS condition (a selector or @media prelude), so
code export can treat variables as design tokens rather than resolved
literals.

Names are derived when not set: Tailwind v4 theme namespaces from the type,
the scopes or the leading name segment, so Gray/50 is --color-gray-50. The
first token to claim an explicit name keeps it; Figma files contain
duplicates, and later claimants fall back to a derived name. FLOAT tokens
infer px except for opacity and font weights. Lengths stay in canvas pixels
and only convert when written, so rem does not change what the canvas or
Figma sees.

In .fig, the name goes to codeSyntax.WEB in the form the snippet already
uses, or to plugin data when WEB holds something else such as a Tailwind
class. Unit, expressions and conditions are OpenPencil plugin data,
validated with Valibot. Conditions and expressions reject braces and
semicolons because they are written into stylesheets, and an expression
whose mode value was edited elsewhere is dropped so the number stays
authoritative.

* refactor: move token naming to dom-css and keep fig to persistence

CSS naming, namespaces and units are CSS projection, which dom-css owns;
scene-graph keeps only the token data and the px/rem storage conversion,
and fig only persists plugin data, validated for shape.

Drop Variable.cssName: codeSyntax.WEB is the single place a token's name
lives, read with postcss-value-parser when it is --x or var(--x), so no
second copy has to stay in sync with Figma's field. Derived names use
es-toolkit kebabCase and twirlwind's Tailwind namespace table, which
excludes opacity since Tailwind v4 has no such namespace.

Whether a condition or expression is valid CSS is no longer guessed with
a regex in fig; the stylesheet generator will check it with cssom where
the string enters a stylesheet.

* refactor(fig): parse token plugin data with Valibot's parseJson

Invalid JSON becomes a validation issue like any wrong shape instead of
a caught exception, and the plugin data lookup reuses
getOpenPencilPluginValue rather than repeating it.

* refactor: use es-toolkit for token expression keys and name segments

mapKeys re-keys expressions by file mode id instead of a manual loop, and
compact drops empty name segments. Reading expressions keeps the plain
filter: pickBy returns Partial<T>, which would need a cast.

* fix: keep token expressions on float32 values and rem precision

.fig stores numbers as float32 while plugin data keeps the resolved value
as a double, so a value such as 1234.567 differed by more than the 1e-6
tolerance and its expression was dropped as stale on reopen. Compare both
at float32 precision.

Token numbers were written with four decimals, which turned 0.5px into
0.0313rem; six keep every pixel step down to 1/1024px exact.

Also note that derived names can collide, so stylesheets take them from
variableCSSNames.

feat: check designs live with a Lint panel, canvas markers, and fixes (#804)
* 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

fix(fig): keep variable metadata, plugin data and default mode on save (#848)
* 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.

fix(fig): read, render, and write Figma slots (#850)
* 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(ai): show what each AI edit changed in its tool call (#812)
* 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.

fix(core): show imported page backgrounds and stop fixed text collapsing
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.

fix(fig): give every exported layer its own order key, and keep the imported ones
* 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.

Co-authored-by: mrhard9090 <74858909+mrhard9090@users.noreply.github.com>

* 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

* 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 (#692)
* 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.

refactor(design-jsx): extract design JSX into its own package (#793)
* 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.

refactor!: register HTML and Tailwind JSX as IO formats (#774)
* refactor!: register HTML and Tailwind JSX as IO formats

HTML and Tailwind JSX went around the IO registry: the CLI appended
`html` to its format list and had its own HTML and Tailwind export paths,
so the app's export options offered neither.

Core now registers `html` and `tailwind-jsx` adapters built on a new
browser-safe `@open-pencil/dom-css/export` entry. Export results can
carry assets written next to the main file, which covers standalone HTML
with external images and fonts, and the CLI writes every format the same
way. The CSS object model and Node file access load only when an export
needs them, so the app bundle stays free of the headless CSS runtime.

BREAKING CHANGE: `sceneNodesToTailwindJSX` and `designDocumentToTailwindJSX`
moved from `@open-pencil/dom-css/browser` to `@open-pencil/dom-css/export`.

* refactor(core): share export support and fixed-size options across IO formats

Five adapters export every target and six have no scale or quality
options; the new HTML and Tailwind JSX adapters repeated those blocks
again. Both are now named once and shared.

* fix(core): keep HTML asset paths relative for Windows output paths

The CLI passed the absolute output path as the export file name, and the
HTML adapter only split it on `/`, so on Windows the page referenced
absolute `C:\...\card.assets` paths and assets were written to a doubled
location. The CLI now passes the file name, and the adapter accepts
either separator.

refactor!: move shared primitives below dom-css and core (#771)
* refactor!: move shared primitives below dom-css and core

dom-css depended on core for color conversion, base64 helpers, text
direction, and web-font assets, so core could not use dom-css and every
caller special-cased HTML and Tailwind output.

Color conversion and management, base64 helpers, and text/layout
direction now live in scene-graph under `color`, `bytes`, and
`text-direction`. dom-css takes web-font resolution as an injected
`fonts` option and owns the font face types, so it depends only on
scene-graph and core can depend on it.

BREAKING CHANGE: `@open-pencil/core/color` and `@open-pencil/core/bytes`
are removed, and the direction helpers are no longer exported from
`@open-pencil/core/text`; import them from `@open-pencil/scene-graph`
subpaths. `exportHTMLBundle` takes a font resolver in `fonts` instead of
`'assets'`.

* fix(tools): import color parsing from scene-graph in visual bisect

* fix(mcp): declare the scene-graph dependency

MCP imports `@open-pencil/scene-graph/bytes` since base64 helpers moved
there, but only reached scene-graph through core, so isolated installs
and package checks depended on transitive resolution.

* refactor!: use js-base64 directly instead of a base64 wrapper

Base64 helpers had moved into scene-graph only to sit below dom-css,
but they are a thin wrapper over js-base64 and unrelated to the graph;
fig already called js-base64 directly.

Callers use js-base64 and check `isValid` where input comes from outside
(clipboard, imported HTML, tool arguments, the plugin API). A new
`open-pencil/no-hand-rolled-base64` lint rule rejects atob, btoa, and
Buffer Base64 conversions, and AGENTS.md records the convention.

BREAKING CHANGE: `@open-pencil/core/bytes` is removed; use `js-base64`.

* fix(dom-css): keep images with invalid Base64 inline in HTML export

`exportHTMLBundle` accepts documents parsed from outside HTML, and
js-base64 drops characters it cannot decode, so extracting an invalid
image data URL wrote different bytes. Such images now stay inline.

refactor!: generate Tailwind JSX through dom-css (#763)
* refactor!: generate Tailwind JSX through dom-css

Core kept its own SceneGraph → Tailwind mapper next to the one dom-css
uses for Tailwind HTML, and the two drifted: HTML export turned grid
frames into flex columns and dropped rotation, inner shadows, blur, and
flex grow, while Tailwind JSX had them.

Tailwind JSX is now printed by dom-css from the same CSS projection as
HTML export, with esrap building the JSX and string literals carrying
text or attributes that JSX would otherwise reinterpret. The projection
gains grid layout and placement, rotation, every shadow, layer and
background blur, flex grow, right-to-left direction, and sections, and
writes opaque colors as hex so Tailwind can match its palette.

BREAKING CHANGE: `sceneNodeToJSX` and `selectionToJSX` in
`@open-pencil/core` no longer accept a format, and `JSXFormat` and
`JSXExportOptions` are removed. Use `sceneNodesToTailwindJSX` from
`@open-pencil/dom-css` or `@open-pencil/dom-css/browser`.

* fix(dom-css): keep backslashes and line breaks in Tailwind JSX attributes

JSX attribute strings keep backslashes literally, but the printer
escapes backslashes and line breaks in string literals, so a layer
named `a\b` came back as `a\\b`. Such values are now written as
expression containers, like values containing quotes or `&`.

fix: escape string attributes in JSX export (#754)
Layer names and other string props were written into JSX attributes
verbatim. A `"` closed the attribute and let the rest of the name add
props or expression containers, which `render` and `replace` then
evaluate. Sucrase also decodes `&` entities in attribute strings, so
names containing entities changed on a round trip.

Strings containing `"` or `&` are now written as expression containers
holding a JavaScript string literal. Tailwind JSX export uses the same
helper for `data-name` and `className`.

refactor(export): derive export format lists from the IO registry (#755)
The Export panel, SDK helpers, app menus, and CLI each kept their own
hand-written format lists, so new formats such as PPTX reached some
surfaces and not others.

Scene Graph now owns the persisted export-setting format ids, Core IO
adapters carry literal ids so that list is checked against real adapters,
and the panel labels, scale handling, app format types, and CLI format
validation/help are derived from the registry. PPTX joins the Export
panel as a result.

fix(fig): harden document worker sessions (#594)
* fix(app): cancel large FIG opens before tab cleanup

- Abort tab-local preparation before awaiting recovery persistence so closing a decoding tab terminates its FIG worker immediately
- Add explicit graph-event unsubscription and lazy FIG resource release for disposed editor stores
- Keep staging-editor disposal separate from live graph resource ownership
- Let same-origin document fetches bypass all cross-origin font response limits

* refactor(fig): isolate worker sessions per document

- Give each lazy FIG document a dedicated MessageChannel and retained worker session
- Route manifest and page population traffic through the session port instead of global worker handlers
- Close the port and worker explicitly on cancellation or tab disposal
- Preserve current lazy source transfer and export fidelity until raw NodeChange patch export is implemented

* perf(fig): preserve unchanged archives in worker sessions

- Keep a second transferable copy of the original FIG archive inside the document worker session instead of main-thread memory
- Track whether user graph mutations invalidate exact archive reuse
- Return unchanged documents byte-for-byte through the session without full-page materialization or recompression
- Release archive request ownership with the page population worker and editor graph resources

* fix(fig): choose the first visible imported page

- Ignore internal-only canvases when selecting the initial active page\n- Keep internal component pages available for lazy instance population

* fix(fig): retain original archives across fallbacks

- Keep session-owned workers alive when population is oversized\n- Register the input archive when worker graph transfer falls back to the main thread\n- Preserve byte-identical unchanged saves without restoring lossy materialization

* fix(fig): harden worker session ownership

- Route concurrent archive replies through persistent request resolvers and reject stale in-flight archives after edits\n- Retain disposal-only handles for oversized sessions and guard Worker construction\n- Reuse the shared FIG import options contract and cover session disposal and invalidation

* test(fig): isolate Worker availability mutation

feat(app): prepare documents atomically per tab (#592)
* feat(app): show atomic document loading progress

- Preserve the existing full-canvas pencil loader while adding phase, detail, accessible status, and honest determinate progress
- Keep one generation-safe load owner across FIG decoding, graph preparation, page population, fonts, fallbacks, layout, viewport fitting, and first-render fade
- Prevent nested page setup and viewport cleanup from revealing partially prepared documents
- Cover obsolete sessions, font-resolution ownership, and staged loader UI

* refactor(app): scope editor preparation per tab

- Replace the shared loading boolean with one reactive preparation snapshot and one imperative controller per editor store
- Keep Core page work progress-only and inject canvas suspension from the app boundary
- Route FIG, storage, recovery, DOM import, and page switching through reusable tab-local preparation handles
- Abort only the closing tab's operation and cover generation safety, multi-tab isolation, progress UI, and disposal

* fix(editor): commit prepared pages atomically

- Prepare population, fonts, fallbacks, and layout without changing the visible page
- Reject cancelled and stale prepared pages before committing viewport, selection, and page events
- Keep the preparation overlay until the committed scene version is presented
- Cover call order, cancellation, stale generations, and presentation acknowledgement

* fix(app): stage imported documents before commit

- Prepare imported graphs in an isolated Core editor before replacing the live document
- Share font loading while keeping live selection, graph, renderers, and history untouched during staging
- Preserve the previous graph when staging is cancelled or fails and remove the duplicate pre-font layout pass

* refactor(app): namespace preparation UI

- Move canvas and tab preparation presentations into focused subfolders with concise component names
- Share progress and phase presentation helpers across preparation surfaces
- Show tab-local preparation status without covering the active canvas for background work

* fix(app): cancel preparation work at source

- Publish typed per-store preparation lifecycle events with explicit completion, cancellation, and failure outcomes
- Propagate tab-local AbortSignals through FIG parsing, population workers, and browser font downloads
- Keep cancellable font requests outside shared in-flight caches while retaining globally completed font registrations
- Stop FIG manifest previews from replacing the live graph before atomic document commit

* fix(app): cancel storage and DOM preparation

- Propagate preparation signals through S3 downloads, byte progress, local-cache boundaries, and DOM/CSS conversion checkpoints
- Reuse merged diagnostics and localized toasts for document, storage, and presentation failures
- Replace manual font concurrency and presentation timers with es-toolkit limitAsync and withTimeout
- Guard stalled first presentation and fix the merged recovery dialog title bindings

* fix(app): stage reload and font retry

- Prepare reload graphs in isolation and preserve the current document on read, decode, font, or layout failure
- Restore page and viewport state only after atomic graph commit with cancellable reload reads
- Run font Retry as a tab-local preparation with cache reset, final layout, picture invalidation, and presentation acknowledgement
- Keep completed document pixels visible while Retry reports activity in the tab

* fix(app): enforce exclusive preparation outcomes

- Complete document, storage, recovery, and DOM preparations only after successful commit
- Keep failed and cancelled handles terminal so lifecycle events cannot report contradictory outcomes
- Preserve external AbortError identity across storage timeouts and cancel streamed readers without returning partial bytes
- Cover credential-free pre-abort, mid-stream cancellation, progress cutoff, and terminal outcome exclusivity

* feat(diagnostics): record preparation outcomes

- Persist completed, cancelled, and failed preparation lifecycles through the validated diagnostics recorder
- Store only operation kind, outcome, cancellation or failure category, terminal phase, and coarse duration bucket
- Exclude document subjects, font families, storage identities, URLs, raw durations, messages, and stack traces

* chore(app): keep browser font tests with typography split

- Remove the browser font transport test inherited from a mixed cancellation commit; the source and coverage remain on the typography branch and safety snapshot

* test(vue): assert injected render suspension

- Exercise shouldSuspendRender instead of removed Core loading state\n- Preserve the contract that rendering resumes without a version change

* test(app): complete atomic preparation contracts

- Acknowledge first presentation in headless file-open tests\n- Assert the cancellable font-loading signature at the Tauri fallback boundary

* fix(app): preserve preparation cancellation

- Stage imported graphs before mutating live tabs and propagate aborts through page, DOM, font, and storage work\n- Use the accessible progress primitive and clamp determinate values\n- Cover fallback-font cancellation and yield pending-open test polling to the task queue

* test(text): await fallback font request cancellation

Start the mocked remote font request before aborting so the test proves that the active request receives the preparation signal.

xemc 783cdf9dbc fix(fig): component property definitions/references/assignments never survive a save/reload round trip
parseGuidOrNull requires the strict Figma GUID shape (sessionID:localID),
but every OpenPencil code path that creates a component property definition
uses `prop:<hex>` IDs, which never match. applyComponentMetadata silently
dropped componentPropDefs/componentPropRefs/componentPropAssignments/
variantPropSpecs whenever any entry failed that check, so any component
property created by the app (as opposed to imported straight from a real
Figma file) vanished on the very next save.

Mint a stable synthetic GUID for non-Figma-shaped property IDs instead of
dropping them, memoized per export so defs/refs/assignments/variantPropSpecs
pointing at the same property stay consistent. Also fix INSTANCE_SWAP
default/preferred/assignment values, which reference target node IDs and
had the same GUID-shape assumption, and were never being resolved back to
real node IDs on import in the first place (remapComponentIds only handled
instance.componentId, not these fields).
