* perf(text): measure each text once per shaping and layout width
Layout asked for the same text at the same width hundreds of times per build, and each request built and laid out a new paragraph. Sizes are now cached beside glyph coverage, keyed by the same shaping inputs, so layout resizing the box keeps them.
* refactor(text): reuse Size for measured text
* perf(text): keep measurements when a paragraph rebuilds for a new box
The paragraph cache dropped coverage and sizes whenever its own inputs changed, including a resize that reaches drawing without a graph update. Shaping compares its own inputs, so it is kept there.
* perf(text): keep glyph coverage when layout resizes a text box
Every layout write invalidated a text node's coverage record by id, and the record compared its width and height, so each measurement shaped the text twice. Coverage now ignores the box size unless the text is truncated, and an update that changes only fields coverage compares keeps the record. A demo load went from about 38,000 coverage checks with 228 hits to one shaping per text node.
* perf(editor): skip component sync for layout's own writes
Layout lays out instances itself, and the edit that made it run has already scheduled its sync. Its size and position writes scheduled about 56,000 more, so each yield of an async build re-synchronised components and re-laid out whole pages.
* 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
Keep successful glyph coverage weakly owned by source nodes rather than repeating shaping when dense scans evict native paragraphs. Preserve font/input invalidation and bound pending ID invalidations without increasing native cache limits.
Add a dense-preview regression with exact raster comparison and count paragraph builds across all canvas renderers. The previous compiled build rebuilds 3,600 paragraphs over three held frames; the fixed build rebuilds none.
Unify preview-aware transforms across scene drawing, labels, selection and input. Give live property and creation edits explicit preview ownership, preserve cancellation and one-step undo, and reuse bounded text preparation resources.
Include retained device-grid handling, worktree HMR coverage, and nested/reflected interaction regressions in this cohesive progress checkpoint.
Validation: full check passes; 734 scoped unit tests and 53 targeted browser tests pass. This is NOT merge-ready: the unchanged exact nested filled-section held/released regression still fails with 63 differing pixels (maximum channel delta 5/255). The browser pass count excludes that separately run failure and the previously classified paint-field-width baseline. Raster-origin investigation and broader acceptance remain outstanding.
