* build: typecheck the test suites
Tests were in no TypeScript program: no tsconfig included tests/** or
packages/*/tests/**, and bun strips types without checking them, so a
fixture could drop a required field and keep passing until something
read it.
@types/bun moves to the root because it was installed per package only,
and #cli-tests/* joins the paths the root config already carries.
* test: fix the type errors the test suites were hiding
Typechecking the tests turned up 1123 errors. Most were ordinary
strictness, but some were real: `NodeChange` bound to Figma's plugin
typings rather than the Kiwi codec in thirteen .fig tests,
materializeInstance was called with six arguments against five so the
blobs and source children were dropped, CanvasKit pixels were written
to a plain object that never reached WASM, and assertions were made
through accessors that do not exist, so they asserted nothing.
Fixtures that had quietly lost a required field now carry it, nullable
results are narrowed through the existing expectDefined helper rather
than assumed, and stand-ins for CanvasKit and the editor go through one
named helper instead of an unexplained cast at each site.
No test was deleted, skipped, or weakened, and no `any`, non-null
assertion, or ts-expect-error was introduced.
* docs: record what typechecking the tests established
Pins the app program's global types with an assertion rather than a
note, since an unpinned types list lets any root @types package decide
which platform src/** is judged against.
The two environment faults that look like code regressions — Vite's
dependency pre-bundle outliving a package rebuild, and heavy .fig
suites failing under load — go to the development docs, where an
explanation belongs.
* fix: align @types/bun and keep node types resolvable when extended
The root manifest declared a newer @types/bun than every package, which
check:monorepo rejects, and pinning the app program's types left them
unresolvable from a config that extends this one out of tree.
* fix: fail the test typecheck when the compiler itself fails
The gate matched diagnostics by substring, so a compiler or config
failure that named no test file printed a pass while having checked
nothing. Diagnostics are now split by whether they name a file: an
unscoped one is the run failing and stops the gate, a test file's is a
finding, and a source file's stays out by design.
Also drops the parameter planComponentConstruction never read, and
makes the inner-shadow verification script exit non-zero when it
renders no image instead of logging and succeeding.
* chore: merge master into tests-typecheck
Reasoning effort was a free-text profile field that only reached OpenAI
and OpenRouter, so Anthropic, Google, and DeepSeek models never thought
in direct chat. AI SDK 7 standardizes a `reasoning` call option that
those providers map to their own thinking settings, so profiles now
store one typed thinking level, shared with Pi, and requests pass it
through that option. OpenRouter's provider ignores the standard option
and receives its own reasoning option instead.
The composer offers the level next to the Design profile and reads it
per request, so a change applies to the next message without
rebuilding the transport. Saved profiles migrate from the Pi level or
the old effort string. Finished reasoning shows how long the model
thought while the block streamed.
* feat: preview streamed JSX on the canvas
Project incomplete JSX into isolated scene graphs and disposable pictures without mutating the document or adding intermediate undo entries. Share placement with final rendering and cover lifecycle and placement parity with AI SDK mocks and visual tests.
* test: require partial input for unfinished coordinates
Assert the complete partial object so rejecting the entire input cannot satisfy the truncated-exponent regression test. Addresses CodeRabbit's review finding on #692.
* feat(ai): keep a chat run on its page across page switches
Page switches go through the editor's preparation flow, and the chat panel treated every preparation as a document change: it dropped its Chat and reloaded history, detaching the panel from a reply still in progress. The panel now keeps the live chat unless the tab or the conversation changes.
AI tools also followed the page on screen, so a user browsing mid-run sent the next edits elsewhere, and the agent's own switch_page affected only one call. A run now pins the page where the message started; switch_page moves the run and the user's view, and streamed previews stay attached to the run's page, which the renderer draws only while that page is on screen.
Page snapshots now restore the page they were taken of, so undoing an AI edit works while another page is visible.
* refactor(core): share picture recording and export preparation with previews
Preview recording reimplemented three pieces Core already had: world-bounds picture recording (also duplicated by render chunks and the retained backing), font and layout preparation (prepareForExport), and page subgraph extraction. Extract recordWorldPicture and withWorldViewport for all three recorders, reuse prepareForExport, and add extractPageContext and findPageChildId next to the other subgraph helpers instead of editing a cloned graph's nodes.
prepareForExport also kept the shared layout text measurer overridden across an await, so a concurrent layout could measure with the export renderer. withTextMeasurer scopes the override to the synchronous layout.
* fix(design-jsx): inline nested fragments in streamed previews
The streaming projection kept a nested fragment as an empty-type node, which rendered trees inline, so a preview of <Frame><>…</></Frame> failed with 'Unknown element: <>'.
* refactor(ai): schedule previews and gate test streams with VueUse
The preview controller hand-rolled a trailing timer and abort-listener cleanup, and the test stream gate a promise resolver and listener set. Use useDebounceFn with maxWait (a lone delta still flushes, unlike useThrottleFn with leading off), useEventListener, and until(). Share the mock token usage between chat tests.
* fix(ai): keep previews alive through document edits and slow builds
Document edits finished every preview call, and onInputStart never restarts one, so a render call committing while a second was still streaming ended the second call's preview for good. Edits now invalidate: drop the shown artifact and rebuild on the new document.
A build that finished after another delta arrived was discarded, so a steady stream that outpaced staging and recording never showed a preview. Show it, then render the newer revision.
* docs(changelog): separate the Fixed heading from its entries
Add the blank line markdownlint (MD022) expects after the heading, and drop the one that split the Fixed list in two.
* feat: persist AI conversations and add chat history
Store transcripts and attachment previews in IndexedDB, separate conversation history from transport lifetime, and add document-aware switching with shared Storybook coverage. Preserve interrupted activity and guard stale writes and async switches.
* test: group chat history tests by domain
* feat: simplify chat history navigation and diagnostics
Use a compact header with searchable document-scoped history and a correctly anchored conversation menu. Move diagnostic copying into the menu with copy-result feedback, and separate Storybook fixtures from composition.
* fix: address chat history review findings
* test: cover harness shutdown and restored chat scrolling
* fix: preserve Portless proxy port in MCP routes
* docs: clarify UI animation conventions
* feat: configure reasoning display and animate disclosure
* fix: separate transcript following from reasoning disclosure
* fix: restore selected chat after document recovery
* refactor: separate chat history persistence and sessions
* style: format reasoning story imports
