* 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.
* fix(ci): keep the review guidance script free of dependencies
The PR review guidance workflow runs the script with plain Node from the default branch without installing packages, so the Valibot import added with the JSON validation work failed with ERR_MODULE_NOT_FOUND on every review and comment event. The script parses the event and pull request by hand again, accepting the null fields GitHub sends, and a test runs it under Node with nothing installed.
* fix(ci): install the review guidance tool's dependencies instead of avoiding them
Restore the Valibot schemas and declare valibot in the tool's manifest. The workflow now installs the tool's workspace from the default branch's frozen lockfile with the shared setup-bun action and runs the script with Bun. The event schema accepts the null fields GitHub sends for absent values.
* 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(app): record MCP and CLI structural edits as undo steps
The automation bridge ran non-atomic tools, render, and eval without an
undo entry, so Edit > Undo could not revert layers an MCP client or the
CLI created, deleted, or rearranged. Snapshot the page around these
edits as the AI chat does, and skip the entry when nothing changed so
read-only scripts leave the history alone.
* feat(app): activate documents, undo, redo, and change settings over automation
Add activate_document, undo, redo, get_settings, and update_settings to
the app's automation bridge. Settings cover appearance, snapping, canvas
rendering, recovery, and chat preferences, validated with Valibot and
applied through their owning stores; credentials, models, MCP
connections, storage, and tool access stay out of reach.
* feat(mcp): expose document activation, history, and settings tools
* feat(cli): manage documents, history, settings, and tools in the running app
Turn documents into a command group (list, open, new, save, close,
activate), add undo, redo, and settings get/set, and add tool
list/describe/call so every MCP tool runs from the shell, against the
running app or headlessly on a file.
* docs: document app control from the CLI and MCP
* fix: never prompt in the app from automation closes and saves
close_file opened the app's Save changes dialog, which an agent cannot
answer: the call timed out and the dialog stayed open. It now fails on
unsaved changes unless the caller passes unsaved "save" or "discard"
(CLI --save or --discard). save_file and new_document no longer open a
Save dialog for a document that was never saved, report a failed save
as an error, and leave the document untouched when the path is refused.
* docs: describe non-interactive close and save
* fix: address review findings in app automation
Keep a document's source when a save to a new path fails, report
vector-edit undo and redo no-ops as unapplied, echo only the applied
patch from update_settings so writing cannot read settings, reject
tool call --write/--output without a file, and stop settings get from
following inherited keys.
* fix(app): record render undo on the page that receives the layers
A render into a parent on another page was snapshotted against the
target page, so undo left the new layers in place. Snapshot the page
that contains the parent instead, and document that eval edits made
after switching pages stay outside the undo step.
* feat(app): limit automation undo to its own steps and expose design check settings
The undo history is shared with the person in the editor, so an agent's
undo could revert the user's last edit. Automation undo and redo now act
only on steps made through the bridge, and only while they are newest;
otherwise they fail and leave the history alone. Vector edit mode's
session history is off limits entirely. Settings automation also covers
the design check preferences that landed on master.
* build: update dependencies
Update the AI SDK providers, Vue, Reka UI, Valibot, Zod, es-toolkit,
CodeMirror, Storybook, Playwright, Hono and other dependencies to their
current releases, consistently across workspaces.
The Tauri plugin packages must match their Rust crates, and the new plugin
crates require Tauri 2.12, so Cargo.lock, @tauri-apps/api and the Tauri CLI
move to 2.12 as well.
* build(harness): update the AI SDK harness packages
@ai-sdk/harness 1.0.74 pinned ai 7.0.67, so the workspace carried a second
copy of ai next to the root one; 1.0.138 depends on the same ai release.
The Pi adapter no longer takes a model: HarnessAgent does. The settings
were spread from untyped records, so the compiler could not reject the
stale key and the chosen model would have been dropped; they are plain
literals now.
PiAuthOptions is now PiAuthenticationMode, and auth accepts an environment
record. Pass the gateway key that way instead of writing it into the
process-wide environment while a session is created. Derive the thinking
level from the adapter's settings, which adds 'max'.
* build: hold vue-tsc at 3.3.11
vue-tsc 3.3.12 no longer sees a v-slot binding inside a component that
also has an event listener, so check:vue reports "Cannot find name
'control'" in MCPConnectionEditor and ProfileEditor. 3.3.11 checks them
cleanly.
* fix(ai): keep retryability for provider errors reported mid-stream
From ai 7.0.80 a provider error after the response stream starts is a StreamProviderError rather than an APICallError, so classifyAIChatError lost its isRetryable.
* feat(desktop): accept updates only when signed for their version
Tauri CLI 2.12 records the app version in each updater signature, and
updater 2.13 checks it against the version latest.json announces. With
requireSignedVersion it also rejects signatures that carry no version, so a
tampered manifest cannot pair a newer version number with an older, still
validly signed bundle.
Release assembly now fails when a signature does not name the version
being released, instead of shipping one that installed apps would reject.
* docs: note the dependency update's security fixes in the changelog
* feat(ai): recommend the latest models
The provider packages now know Claude Sonnet 5.5 and Opus 5.5 and the GPT-6
series. Make Sonnet 5.5 and GPT-6.1 Sol the defaults, list Opus 5.5, Fable
5.1, GPT-6 Astra and GPT-6 Luna, and replace the two free OpenRouter models
that OpenRouter no longer serves.
* build: align the fig package's valibot with the workspace
* refactor: rename @open-pencil/codegen to @open-pencil/emit
In design tools codegen means design-to-code, which is dom-css's job and
Core's codegen tools'. The package builds and prints the syntax trees
exporters emit, so name it for that. It has not been released yet.
* fix: alias @open-pencil/emit to its source in Vite
The rename missed the escaped regex, so Vite resolved the package through
its built dist output.
* 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.
0.4.0 maps var() references to @theme variables onto their utilities,
which design-token export will use, and parses CSS values with
postcss-value-parser instead of regular expressions, fixing lossy
shorthand, filter, transform and media-query conversion.
* feat(core): add visual diff and patch apply tools
diff_visual renders two nodes at one scale through the existing raster export, compares them with pixelmatch, and returns the diff PNG with the changed ratio and region in source-node coordinates. It takes export_image's scale and maxEdge inputs. FigmaAPI gains a CanvasKit-backed raster codec and a pageId export option, so the app and headless CLI decode pixels and render nodes off the current page.
diff_apply applies diff_create and diff_show patches through the Figma API, validates every node before changing any, and supports dryRun and force. diff_show now simulates changes on a detached copy with the same property code. One serializer and parser back all three. diffDocuments compares two documents page by page by name path.
Image tool results now reach models as media with their metadata as text, for any tool rather than export_image alone. diff_create, diff_jsx, and diff_visual join the default AI tool set, and the diff tools are no longer hidden from WebMCP.
* feat(ai): show what each AI edit changed in its tool call
Reviewing an AI run meant reading tool output or undoing steps to see
what moved. Each document-changing call now rebuilds its page before
and after from snapshots taken around it, and diffs each top-level
layer's JSX with jsdiff, the same patch diff_jsx returns, to find the
layers it changed. After the call returns, the changed region renders
in both states at one size and pixelmatch highlights the difference.
The tool card opens on a Changes view with a before/after slider, the
pixel highlight, and a CodeMirror merge view of the JSX. Records are
saved with the conversation next to attachments.
Calls snapshot their page individually instead of through one shared
variable, so concurrent calls in a step no longer overwrite each
other's undo state. Core gains graphFromPageSnapshot for rebuilding a
past page state, diffPageLayersJSX and jsxPatch (now shared with
diff_jsx), renderRegionToImage for rendering two states of one region
pixel for pixel, and comparePNGs on the raster codec. Settings > Chat >
Change previews sets the stored image size or turns images off.
* feat(cli): add diff commands and agent diff guidance
openpencil diff create, jsx, show, apply, and visual run the Core diff tools on a file or the running app; apply writes back with --write or --output like eval. diff files compares two documents page by page and exits 1 when they differ.
The chat prompt asks the agent to edit in place and to verify risky edits against a reference copy with diff_jsx, diff_create, and diff_visual. The skill, CLI reference, MCP tool table, and a new Comparing Designs page document the commands and tools.
* feat(ai): render tool calls as summarized, highlighted cards
Every tool call showed only a status and its output as a JSON string,
so render calls hid their JSX, export_image dumped base64, and long
runs filled the transcript with identical rows.
A call now shows a one-line summary read from its input and chips that
select and zoom to the layers it touched, switching to the run's page
when needed. Expanded, it shows the JSX or script it wrote and its
JSON input and output in a read-only CodeMirror view, and exported
images inline. Render calls can be expanded while their input streams,
so the JSX appears alongside the canvas preview. Consecutive calls
beyond three fold into one row that keeps the latest call visible.
CodeMirror loads with the first expanded call. The code theme gains a
monospace fallback because the editor font variable is not always
emitted.
* feat(ai): let the chat AI diff its run against the starting state
The diff tools compare two nodes, so checking an edit meant cloning a
reference first, which the agent rarely did. diff_changes compares the
current page, or one node under it, with the page as it was before the
run first edited it, in diff_create's patch format. The app keeps that
page snapshot per run and exposes it through FigmaAPI.changeBaseline;
MCP and WebMCP have no run, so the tool is offered only to the AI chat,
where it is enabled by default and the prompt asks for it before
reporting.
* feat(core): diff and patch node trees as JSX attributes
diff_create, diff_show, diff_apply, and diffDocuments used a hand-rolled
`key: value` property format that covered about fifteen properties,
matched children by name path, and could not see moves.
Nodes are now projected to the attributes the JSX export prints, and
jsondiffpatch matches children (by ID or by name path) and detects
moves. Patches list `-`/`+` attribute lines per node plus moved, added,
and removed children. diff_apply checks every hunk first, applies
attribute changes through the renderer's prop handling, and changes only
the fields an attribute moves, so IDs, instance links, and other state
survive. diff_show takes JSX attributes instead of a JSON props object.
design-jsx gains sceneNodeAttributes, parseJSXAttributes, and
jsxNodeFields for this, and the export round-trip property table is
shared so every case is also diffed and applied. `diff files` loads its
documents in order so node IDs, and so its patches, are deterministic.
* feat(ai): report diff_changes as a patch diff_apply can replay
diff_changes printed a unified diff of the JSX, which agents could read
but not apply. It now diffs the run's baseline against the live page
with the patch engine, matching nodes by ID, so a rename is a changed
name and the output replays on the starting state with diff_apply. The
chat's Changes view keeps the JSX line diff, which is for people.
* fix(core): keep diff_apply atomic and diff files honest about differences
- Added nodes render before anything else changes; if one fails, for
example on a missing component, the rendered ones are deleted and
nothing else is committed.
- A hunk with an attribute the renderer ignores fails instead of
reporting "unchanged".
- diffDocuments reports `changed` from page statuses, and a page only
one document has gets its status but no patch, since patches do not
add or remove pages. diff files uses it, so an added empty page no
longer reads as a match.
- diff files rejects a --page neither document has and a --depth that
is not a non-negative integer, exiting 2; diff_create's depth is
validated the same way.
* refactor(ai): drop the unused tool JSON slot and place the JSX summary comment
* refactor(ai): find a tool change's clipping region with jsdiff
clipChangedJSX scanned both JSX sources character by character for their common start and end. diffLines gives the unchanged lines before the first change and after the last; the app now declares the diff dependency Core already uses.
* feat(ai): render tool calls as summarized, highlighted cards
Every tool call showed only a status and its output as a JSON string,
so render calls hid their JSX, export_image dumped base64, and long
runs filled the transcript with identical rows.
A call now shows a one-line summary read from its input and chips that
select and zoom to the layers it touched, switching to the run's page
when needed. Expanded, it shows the JSX or script it wrote and its
JSON input and output in a read-only CodeMirror view, and exported
images inline. Render calls can be expanded while their input streams,
so the JSX appears alongside the canvas preview. Consecutive calls
beyond three fold into one row that keeps the latest call visible.
CodeMirror loads with the first expanded call. The code theme gains a
monospace fallback because the editor font variable is not always
emitted.
* refactor(ai): drop the unused tool JSON slot and place the JSX summary comment
* fix(ai): keep an opened tool call in place instead of following the output
Opening reasoning already stopped the transcript from following new output; tool calls and tool groups did not, so expanding one near the bottom re-pinned the bottom on every animation frame and slid the card away as it opened. Any disclosure in the transcript now stops following.
* fix(ai): show a pointer over chat tool calls, tool groups, and reasoning
* refactor(app): share CodeMirror setup between the code editor and viewer
CodeViewer repeated CodeEditor's view lifecycle: mounting the EditorView, label, theme, and language compartments, the app-theme watcher, and teardown. useCodeMirror owns that once; each component passes its own fixed and reactive extensions.
* refactor(ai): move tool node lookup and focusing into useToolNodes
ToolNodeChips looked nodes up in the active document and ran the show-on-canvas flow, with its superseded-switch and error handling, inside the component. The composable owns both; the component renders the chips.
* refactor(ai): derive tool call state and input once
ToolCallCard and ToolCallGroup each rebuilt classifyToolState's input from the part, and the card decided inline whether a call had input to show. toolCallState and toolHasInput own those rules beside the other per-call helpers.
* fix(app): use the thin app scrollbar in code editors and viewers
CodeMirror scrolls its own .cm-scroller, which fell back to the platform scrollbar, thick and light in the dark chat. The hosts now give it the shared scrollbar-thin utility.
* feat(core): add visual diff and patch apply tools
diff_visual renders two nodes at one scale through the existing raster export, compares them with pixelmatch, and returns the diff PNG with the changed ratio and region in source-node coordinates. It takes export_image's scale and maxEdge inputs. FigmaAPI gains a CanvasKit-backed raster codec and a pageId export option, so the app and headless CLI decode pixels and render nodes off the current page.
diff_apply applies diff_create and diff_show patches through the Figma API, validates every node before changing any, and supports dryRun and force. diff_show now simulates changes on a detached copy with the same property code. One serializer and parser back all three. diffDocuments compares two documents page by page by name path.
Image tool results now reach models as media with their metadata as text, for any tool rather than export_image alone. diff_create, diff_jsx, and diff_visual join the default AI tool set, and the diff tools are no longer hidden from WebMCP.
* feat(cli): add diff commands and agent diff guidance
openpencil diff create, jsx, show, apply, and visual run the Core diff tools on a file or the running app; apply writes back with --write or --output like eval. diff files compares two documents page by page and exits 1 when they differ.
The chat prompt asks the agent to edit in place and to verify risky edits against a reference copy with diff_jsx, diff_create, and diff_visual. The skill, CLI reference, MCP tool table, and a new Comparing Designs page document the commands and tools.
* feat(core): diff and patch node trees as JSX attributes
diff_create, diff_show, diff_apply, and diffDocuments used a hand-rolled
`key: value` property format that covered about fifteen properties,
matched children by name path, and could not see moves.
Nodes are now projected to the attributes the JSX export prints, and
jsondiffpatch matches children (by ID or by name path) and detects
moves. Patches list `-`/`+` attribute lines per node plus moved, added,
and removed children. diff_apply checks every hunk first, applies
attribute changes through the renderer's prop handling, and changes only
the fields an attribute moves, so IDs, instance links, and other state
survive. diff_show takes JSX attributes instead of a JSON props object.
design-jsx gains sceneNodeAttributes, parseJSXAttributes, and
jsxNodeFields for this, and the export round-trip property table is
shared so every case is also diffed and applied. `diff files` loads its
documents in order so node IDs, and so its patches, are deterministic.
* fix(core): keep diff_apply atomic and diff files honest about differences
- Added nodes render before anything else changes; if one fails, for
example on a missing component, the rendered ones are deleted and
nothing else is committed.
- A hunk with an attribute the renderer ignores fails instead of
reporting "unchanged".
- diffDocuments reports `changed` from page statuses, and a page only
one document has gets its status but no patch, since patches do not
add or remove pages. diff files uses it, so an added empty page no
longer reads as a match.
- diff files rejects a --page neither document has and a --depth that
is not a non-negative integer, exiting 2; diff_create's depth is
validated the same way.
* refactor(codegen): share syntax-tree code generation between exporters
dom-css printed Tailwind JSX with its own esrap JSX builders and kept TypeScript template helpers under its Storybook export. The OpenPencil JSX exporter needs the same JSX builders, and design-jsx and dom-css may not depend on each other.
@open-pencil/codegen holds both: es for ESTree templates and modules (moved from dom-css) and jsx for JSX elements, attributes, text, and printing, including the literal rules that keep exported strings from being reinterpreted. dom-css no longer depends on acorn and esrap directly.
* refactor(design-jsx): print JSX export as syntax trees
sceneNodeToJSX concatenated strings with hand-written escaping and indentation. It now collects typed props (moved to export/props.ts) and prints them with @open-pencil/codegen's JSX builders. Output is unchanged except for text: special characters print as a string expression instead of entities, and multi-line text keeps its line breaks, which the old line-splitting lost on render.
* docs(codegen): fix package metadata and dependency rules
codegen's repository.directory still named design-jsx, the README mentioned es without showing it, and the design-jsx and dom-css guides still said they depend only on scene-graph.
* test(core): move the JSX export round-trips to the design-jsx test home
Covers tabs in layer names and text, which JSX keeps as written.
* 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.
* build(core): import Markdown with unplugin-raw
Core inlined ?raw imports with a hand-written Rolldown plugin that also turned plain .md imports into strings, which nothing in Core uses. unplugin-raw already does this for the Vue SDK and design-jsx; use it here too and drop the unused *.md module declaration.
* refactor(pen): use the scene-graph color parser
pen/src/color.ts duplicated parseColor from @open-pencil/scene-graph/color line for line. Import it instead, which also drops pen's direct culori dependency.
* fix(figma-api): validate effects like Figma
The effects setter stored whatever a script passed, so scripts that Figma rejects ran here and malformed effects reached rendering and .fig export. Validate against Figma's effect shapes with Valibot, recorded from live Figma: strict objects, required shadow fields, radius >= 0, RGBA channels within 0..1, and no shadow fields on blurs. The getter now returns Figma's shape so node.effects = node.effects keeps working.
Closes#786
* fix(figma-api): reject infinite numbers in effects
Figma rejects Infinity in every effect number ("Number must be finite"), but v.number() accepts it, so infinite radii, offsets, and spreads reached the scene graph.
* fix(figma-api): store PASS_THROUGH shadow blend as NORMAL
PASS_THROUGH is a layer blend mode. Live Figma accepts it on drop and inner shadows but reads NORMAL back, so do the same instead of storing it.
* refactor(design-jsx): extract design JSX into its own package
Design JSX elements, helpers, schema, reference, and JSX export only need
the scene graph, yet lived in Core, so every consumer of the authoring API
pulled in the renderer, layout, and file formats.
@open-pencil/design-jsx now owns them and depends only on scene-graph. The
renderer takes icon lookup, SVG conversion, vector creation, and layout as
DesignJSXServices; Core binds its own and exports the bound renderJSX and
renderTree from @open-pencil/core/design-jsx.
* feat(design-jsx): export the JSX runtime for TSX authoring
The package already had a JSX runtime, but nothing exported it, so design
trees could only be written as function calls or JSX strings. Export
`./jsx-runtime` and `./jsx-dev-runtime` so `jsxImportSource` works, and make
`Fragment` produce the same empty-type node as `<>` in `renderJSX` strings.
* fix(design-jsx): render fragments nested in other elements
A fragment builds a node with an empty type, which only renderJSX expanded, and only at the root. Nested fragments and fragments passed to renderTree failed with 'Unknown element: <>'. Inline fragment children when trees are built, and share root expansion between renderTree and renderJSX.
The 54 editor engine tests move to packages/core/tests/editor with their helpers, importing Core's public subpaths or source modules relatively. The package gains test and typecheck scripts; the first type check fixed nullable lookups, stale imports, and renderer doubles, and graph events now declare the GraphEventRenderer surface they invalidate. The engine baseline drops to 534 files.
Tools live under tools/<role>/<domain> (checks, generate, release, ci, dev), every tool is a workspace named @open-pencil/<domain>-tools, a shared tools/tsconfig.json backs the new check:tools gate that fixed 55 latent type errors, test:tools runs through bun --filter, the placement check is its own checks/test-homes package, and every tool resolves the repository through resolveWorkspaceRoot. Bun, Node, and mdast types live in a tools-root workspace so they never reach the app program.
Scene Graph unit tests move to packages/scene-graph/tests with a package-local assert helper and test type-checking; five Core- and fig-owned tests move to their owners' engine homes. check:test-homes rejects any new test under tests/engine against a reviewed baseline so the migration debt only shrinks.
* feat(cli): export components as Storybook stories
Add `openpencil export -f storybook`, which writes one CSF3 `.stories.ts`
file per component set or component. Each variant becomes a story and the
variant properties become select controls, so the story renders the matching
variant; an unknown combination throws instead of showing another variant.
Stories embed the existing inline-style HTML projection, so consumers need no
OpenPencil runtime. `--framework react|vue|html` only changes the render
wrapper and the Meta/StoryObj import. When the document sits under the current
directory, stories carry an `openpencil://` design link for
@storybook/addon-designs.
Refs #727
* fix(pen): size auto-width text from its content on import
Text without a width in an auto-layout parent was imported 10000px wide, a placeholder the app's text measurer replaces. Headless layout keeps stored sizes, so CLI HTML and Storybook exports stretched hugging frames to over 10000px. Import the width as 0 so the importer's existing text-length estimate applies, and headless layout estimates the rest.
* feat(app): follow layer links to other pages
openpencil:// and web ?node= links only searched the current page, so a Storybook story linking to a component on another page reported it missing. When the current page has no match, load the other pages without showing them and switch to the first that carries the name.
* feat(cli): add design images and watch mode to Storybook export
Each story now links to its own variant when the layer name is unique, and carries a 2x PNG of the variant for @storybook/addon-designs, imported so Vite bundles it. --watch re-exports on every save. Re-exports replace the stories a previous export of the same document generated, including those of deleted components, and refuse to overwrite hand-written stories or another document's.
Refs #727
* fix(cli): reference Storybook design images without ambient PNG types
Import design images with new URL(..., import.meta.url) instead of an import declaration, so consumers need no vite/client types to typecheck the stories. Document that exports should run from the same directory.
* fix(app): search other pages for a link without cancelling page switches
The cross-page layer search prepared each page with preparePage, which advances the page-switch generation, so a page switch the user had in progress could be dropped, and every searched page paid for fonts and layout. Add loadPageNodes, which populates a page's layers through the same worker path without touching the switch generation, and report a failed search as an error instead of a missing layer.
* fix(pen): never import width-less text zero wide
Text without a width now imports at width 0 and relies on the importer's text-length estimate, which skipped single-glyph text. Estimate zero-width text of any length.
* fix(cli): harden Storybook export ownership, titles, and links
- A --page export replaces only its own stories, and names files as a full export does, so it cannot delete or overwrite other pages' stories.
- Same-named components on a page get distinct titles, so Storybook story ids do not collide.
- Read the generated header through CRLF line endings, and refuse a source containing a line break, which would end the header comment and start code.
- Link a story only to a layer name no other layer carries.
- Document the --page default for Storybook export.
Refs #727
* fix(app): let a page switch overtake a link's layer search
A link search that loads other pages could resume after the user started switching pages and move them to the matching page. Expose pageSwitchCount, which advances whenever a page switch starts, and abandon the search when it changes. An overtaken search reports neither a match nor a missing layer.
* fix(pen): estimate only omitted text widths
Estimate a width-less text node's width when it is imported, instead of estimating every zero-width text node afterwards, so an explicit width of 0 is kept.
* fix(cli): track Storybook story ownership by document path and page
- Identify the document by its path relative to the output directory rather than a basename or cwd-relative path, so same-named documents do not share stories and the export no longer depends on the working directory.
- Record the page in each story's header; a --page export replaces all of that page's stories and asks for a full export when renumbered file names land on another page's.
- Check every target, including design images, before removing anything, and refuse to overwrite files this export does not own.
- Quote the header fields as JSON with U+2028/U+2029 escaped, so any path stays inside the comment, instead of refusing line breaks.
- Deduplicate titles by Storybook id, which ignores case and punctuation.
Refs #727
* fix(app): focus a searched page only after its switch committed
A page switch the user starts while the link search's own switch is pending can keep that switch from committing. Check that the search's switch was the only one and landed on its page before focusing; otherwise report the search as superseded.
* fix(pen): keep empty text without a width at zero
* fix(cli): remove only the design images a Storybook export generated
Replacing a story removed its whole .design folder, including files someone else put there. Read the images each owned story references, remove just those, and remove a .design folder only once it is empty.
Refs #727
* test(app): cover a page switch still pending during a link search
The previous test committed the overtaking switch, so the page check alone caught it. Advance the switch count without committing, so the test fails without the count check.
* fix(cli): stage Storybook exports and refuse linked design folders
- Write every file to a staging folder inside the output before removing the previous export, then move them into place, so a failed write no longer leaves the export half replaced.
- Refuse a .design path that is not a real folder, such as a symbolic link, before removing or writing images through it, so an export cannot reach outside the output directory.
Refs #727
* refactor(dom-css): print Storybook stories from a parsed template
Story modules were assembled from string fragments, so quoting and
layout were an implicit contract: the CLI found design images with a
regex that only matched double-quoted `new URL("…")` paths.
A story module is now one TypeScript template, parsed once with acorn
and its TypeScript plugin. Data is filled into `$placeholder` nodes and
the module is printed with esrap, which owns quoting and escaping. The
CLI reads referenced design images back through `storyImagePaths()`
instead of matching text. Tests import generated modules and assert
values rather than formatting.
* refactor(storybook): track generated files in a manifest
The export recovered which files it owned by parsing its own output: a
header regex over JSON-quoted strings, line-separator escaping, CRLF
handling, an AST walk for design images, and a path regex in the CLI.
A `.openpencil-stories.json` manifest now records the document and page
behind each generated file. The CLI validates it with Valibot, including
that every listed path stays inside the output folder, and the story
header is a plain note. Story ids use a copy of Storybook's `sanitize`,
tested against the installed Storybook; the previous rule treated `A§B`
and `A-B` as the same story. Export names use es-toolkit's `pascalCase`.
The CLI export command moves into `commands/export/`, dom-css splits
grouping and naming out of the Storybook exporter, and the CLI takes the
framework list from dom-css.
* fix(pen): keep explicit narrow text widths
A post-import pass widened every multi-character text narrower than two
font sizes, including widths the `.pen` file set on purpose, such as
`width: 0`. Omitted widths are now estimated when the text node is
created, so the pass only overrode explicit widths and is removed.

* 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
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(tools): run npm packaging guards in package verification
The packed-resolution unit tests spawned npm pack, npm init and npm
install under Bun's default 5 s test timeout, and npm's cold start on a
fresh CI runner exceeded it. Package-manager work is not bounded by a
test budget, so the fixture chain becomes a packaging-guard phase of
test:packages: fixture manifests packed with the release's npm pack,
inspected, installed through the real consumer install and imported
under Node and Bun, each with the outcome it must produce.
The tarball inspector reads archives in-process with @publint/pack
instead of a tar executable. Its bun test coverage is now pure unit
tests plus in-process tarball fixtures.
* fix(tools): bound npm init and build tarball fixtures in-process
The consumer install helper gave npm install a deadline but not npm
init, so a stalled init could hold the packaging-guard phase open. The
inspector tests built their archives with a tar executable, which
contradicted what they claim to prove; nanotar now writes them
in-process.
* refactor(tools): alias package tool tests and compare guards with isEqual
package-artifacts and package-quality were the only tools without a
#domain/* subpath alias, so their tests reached into ../src. Both now
declare the alias like the other tools and the tests use it. The guard
diagnostic comparison uses es-toolkit's isEqual instead of joined
strings.
* fix(tools): match the expected runtime failure in packaging guards
A guard that expected Bun to fail accepted any non-zero exit, so an
unrelated error would have satisfied it. Failing expectations now carry
the resolution error Bun must report, and observations keep the actual
output so a mismatch names what happened instead.
* fix(tools): evaluate calc expressions without expr-eval
expr-eval has an unpatched critical advisory for code execution through
toJSFunction(), which compiles expressions with new Function
(GHSA-q9v2-7m5w-4693). The advisory covers every published version, so
`bun run check:audit` fails on every branch and `bun audit fix` has nothing
to upgrade to. The calc tool only ever called evaluate(), so the advisory's
own vector was not reachable, but the dependency stays flagged and the
evaluator's surface was far wider than the tool documents: random(), factorials,
trigonometry, constants, strings, array indexing, property access and
statement sequences all evaluated, while the documented ** operator did not
parse at all, since expr-eval spells power as ^.
Replace it with a recursive-descent evaluator for exactly the documented
grammar. It compiles nothing, reaches no host object, and fixes **, which is
right-associative and binds tighter than a leading sign, so -2 ** 2 is -4 as
in ordinary notation. Non-finite results are still reported by the tool rather
than the evaluator, so 1 / 0 keeps its "Produced Infinity" message.
The tool had no tests; both the evaluator and the tool's JSON-array and
error-reporting paths are covered now.
* refactor(tools): parse calc expressions with jsep
Replace the hand-written tokenizer and recursive-descent parser with jsep,
a maintained zero-dependency expression parser with no advisory history, and
keep only the tree walk: an allowlist of node types, arithmetic operators and
the documented functions. Parsing, where the vulnerabilities in this class of
library live, is no longer ours to maintain.
Behaviour follows the parser rather than the previous hand-written precedence,
so a leading sign now binds tighter than '**' and '-2 ** 2' is 4; the tests
pin that alongside right-associativity. Parse errors keep jsep's own wording
and character positions.
* fix(tools): reject inherited names and fold long calc argument lists
Two findings from review of this branch. The function lookup used `in`, so
an inherited key such as `constructor(1)` passed the guard and then failed
while destructuring a missing arity, reporting a TypeError instead of an
unknown function; it now uses Object.hasOwn. min and max spread their
arguments, which overflows the call stack on V8 at roughly 125k arguments,
so they fold instead. Both paths are covered by tests.
* fix: explain unsupported browsers instead of a blank window
The desktop app on macOS 13 with WebKit older than Safari 17.4 opened an
empty window because startup called Promise.withResolvers, which Vite lowers
nothing for: build.target only rewrites syntax and never polyfills APIs, and
the target itself was an implicit Vite default (#744).
Make the supported baseline explicit in src/app/shell/support/baseline.ts and
feed it to build.target, a lint rule that rejects newer static built-ins in
browser-shipped sources, and the documented system requirements. Replace
Promise.withResolvers with a createDeferred() helper.
Turn src/main.ts into a small gate that checks sentinel features before
dynamically importing the app, so an old engine still evaluates enough code
to render platform-specific update guidance: macOS/Safari via Software
Update, WebKitGTK and WebView2 on Linux and Windows, and each browser's
own update path on the web, with a prefilled bug report link. Render-blocking
errors during the first route are captured through app.config.errorHandler
and shown the same way instead of leaving the window blank.
Desktop facts come from tauri-plugin-os and a webview_version command; the
bundle now declares macOS 13 as its minimum system version.
* build: enforce the browser baseline from compatibility data
Replace the hand-maintained list of built-ins newer than the baseline with
two data-driven checks. The app and browser-shipped packages pin their
TypeScript lib to ES2023, the last edition Chrome 111, Firefox 128 and
Safari 16.4 implement in full, so a newer built-in such as
Promise.withResolvers fails type-checking. Web APIs, which lib.dom does not
version, go through eslint-plugin-compat under oxlint with the same browsers
in settings.browsers, scoped to sources that ship to a browser.
A unit test keeps the oxlint browser list and the tsconfig libs derived from
src/app/shell/support/baseline.ts, so the three cannot drift apart.
* fix: recognise production error codes in the boot observer
Vue passes the error reference URL as the errorHandler info argument in
production builds instead of the development string, so the observer never
classified a setup or render failure as fatal in the shipped app and the
boot-failure notice only appeared on the dev server. Match Vue's exported
ErrorCodes in both forms, and cover the component-setup path in the E2E
spec; the scenario was also verified against a production build.
* fix(app): protect unsaved documents when closing
Mark tabs with unsaved content updates and ask whether to save before
closing them. The prompt now covers tab closes, the desktop window close
button, and the application Quit action, which previously discarded work
when autosave had no writable target.
Track a content revision separately from scene and recovery versions so a
save only clears the indicator when it wrote the revision it captured.
Cancelled pickers, failed writes, and edits made during a save keep the
document open. Desktop uses the platform alert; the browser keeps the
styled dialog.
The desktop menu replaces the predefined Quit item so the accelerator and
Dock-independent quit path request confirmation instead of exiting.
* fix(ai): resolve credentials only when used
Opening a document, creating a chat, or browsing chat history connected
the provider and read saved secrets, which triggered system credential
prompts without user intent.
Startup now reads credential status only, migration runs inside the first
explicit resolution, and the chat panel initializes local history without
creating a transport. Stock-photo keys resolve per search instead of at
settings refresh, and credentials still marked legacy count as configured
so upgrading does not appear to lose them.
* refactor(ai): export diagnostics from Settings only
Chat kept its own debug log, copied mixed app-wide usage into a
conversation export, and reported a missing cache rate as zero. Remove
that surface and record AI requests, model steps, and tool activity as
correlated diagnostic events instead.
Settings remains the single export location, usage summaries can now
distinguish unreported telemetry from zero, and transcript or tool
payloads are no longer part of the export.
* fix(ai): clear legacy credentials for real
Clearing a Pexels, Unsplash, or provider key only removed the current
store entry. A value that still lived in legacy storage kept the key
configured, so a later search migrated and used the credential the user
had just removed.
Migrate before mutating so clearing also removes the legacy value, and
share one in-flight migration so the media and provider paths cannot
migrate the same plaintext twice.
* fix(ai): scope credential migration per source
Sharing one migration promise process-wide let a second storage return
the first migration's result, leaving its own legacy keys unmigrated
while reporting success. Track in-flight migrations per storage and
serialize them, because every migration writes to the same store and
concurrent runs could overwrite each other.
* fix(app): destroy the window after a confirmed close
Tauri's onCloseRequested helper destroys the window itself when a handler
returns without preventing the event. Approving a close therefore invoked
plugin:window|destroy, which the capability set did not grant, so the
window stayed open with a permission error after saving.
Always intercept the request and destroy the window explicitly once the
choice is confirmed, and grant core🪟allow-destroy in place of the
now-unused close permission.
* fix(app): show a filled dot for unsaved tabs
The unsaved indicator used a stroked Lucide circle whose fill attribute
kept it an empty outline, reading as a disabled control. Draw the
indicator as a filled accent dot matching the status dots used elsewhere
in the app.
* refactor(app): focus the unsaved prompt with VueUse
Replace the manual watcher, nextTick, and component $el focus with
useFocus, which focuses the Save button when the dialog mounts. Assert the
focus in the close-protection test so the Return-saves behavior stays
covered.
* refactor(app): route Quit through the shared menu channel
The Quit item emitted a bespoke app:request-exit event and the close
module listened for it, while every other native item travels as a
menu-event id dispatched by the shell and editor menu composables.
Emit menu-event "quit" for both the Quit item and the platform exit
request, handle it in useShellMenu beside check-updates, and share one
confirmAppExit so window closes and app exits agree on a single approval.
* refactor(app): generate the macOS app menu entries
The application menu hardcoded its labels and the Quit accelerator in
Rust while every other menu entry is generated from APP_MENU_SCHEMA.
Move the custom app entries (About, Check for Updates, Quit) into
APP_MENU_APP_ITEMS and emit desktop/generated/app-menu.json, keyed by id
so the native builder cannot silently drop a label.
Placement stays in Rust because the OS-predefined items sit between them,
and the menu title now comes from the packaged product name.
* build(tauri-menu): check generated menus against the schema
The generated menu files are committed but nothing verified them, so a
schema edit could silently leave desktop/generated stale until the next
release build regenerated it.
Split the renderers from the write step, register the tool as a workspace
so its dependencies resolve, and compare the committed files with the
schema in a test that runs with the other tool checks.
* fix(app): serialize exit confirmations
The window close handler and the Quit item both call confirmAppExit, and
the per-handler closing flag does not cover the two paths. Both could run
close preparation, so an unsaved document could be prompted twice.
Share one in-flight confirmation and clear it when it settles, so a
cancelled or failed attempt still prompts again on the next request.
* ci: fix desktop build cache ownership
* build: centralize native release artifact validation
Reuse package command execution and npm artifact paths. Share release identity and target metadata, consume explicit Tauri artifact outputs, and reject incomplete or mixed-run artifact sets before draft publication.
* refactor: use release package aliases across directories
* ci: coordinate verified native and npm releases
Build shared frontend inputs once and keep native targets parallel. Bind their complete artifact set to immutable source and workflow revisions, verify updater signatures and attestations, and replace draft assets only after preflight and verified npm publication.
* test: group native release tests by domain
* feat: refresh branding with generated platform icons
Keep the approved mark and optical micro master as the source of truth. Generate web, documentation, and native assets at their owning build boundaries instead of storing raster variants or linking web icons to desktop output.
* fix: refine small brand marks and loading artwork
* feat: adopt blue editing-handle brand mark
* feat: refine teal branding for light and dark themes
* feat: apply ivory tiles across brand surfaces
Use edge-to-edge web tiles with a larger mark and optical micro favicons. Preserve native spacing and platform-owned maskable/touch cropping. Address review feedback on story props, native dimensions, and brand test type checking.
* test: allow cold npm startup in packaging fixture
CI hit Bun's five-second default while running npm pack --dry-run. Give this integration test a scoped 30-second budget without changing production timeouts or other tests.
Welcome AI-assisted contributions while reserving co-author trailers for human credit. Reuse commitlint and Git trailer parsing to reject known assistant identities in new commits without altering existing history or legitimate credits.
Define native Valibot inputs and execution/exposure metadata on each tool. Derive effects and default capabilities, consume upstream Standard Schema conversion, and validate finite numeric inputs consistently across adapters.
Move atomic execution to Core and restore failures from Scene Graph checkpoints without relying on a property diff. Preserve topology, collections, indexes and surviving object identities during rollback.
BREAKING CHANGE: custom tools use input schemas and execution metadata instead of params, ParamDef and independently declared mutation flags. Direct tool execution validates inputs before invoking the handler.
Remove the disabled widening audit and its resolver. Fix Bun aliases and bounded reducer slices, reject parser failures in shared fixtures, and retain upstream attribution in NOTICE.
Share canonical tool inputs with AI and browser adapters through Valibot and Standard Schema while retaining MCP numeric coercion and existing transports.
BREAKING CHANGE: programmatic integrations use SDK v2 server/client types; paramToZod is removed in favor of the shared Core tool input contract.
Prevent module registry mocking, repeated reducer accumulator copies, and local widen-then-assert flows. Keep known-value widening available for audits without enabling its noisy global policy, and record upstream provenance for the adapted rules.
