Top-level selection copies were safe, but nested fill and child arrays still aliased graph data. Clone initial node values and only the changed preview fields so mutable consumers cannot bypass graph tracking or cancellation. Preserve field-granular updates and paused subscriptions.
Discard provisional undo batches on graph replacement without replaying old document edits or clearing committed history. Reset failed preview controllers and refresh selected projections for plain-state SDK consumers while pausing inactive subscriptions.
Cover the verified review findings with negative controls, fix static Vue host insertion, and preserve the shared exact renderer oracle with its independently verified sRGB selection color.
Use native paragraph foreground paints instead of independent outline layout, keeping mutable shader paragraphs transient. Render transformed diamond gradients with a retained, owned runtime program and align Skia surface encoding with the browser drawing buffer.
Add independent pixel and ownership regressions and correct only the reviewed text, gradient and FIT-image visual oracles. Existing arrow/blur snapshot failures and the separate 84-pixel comparison remain unresolved; no tolerances are relaxed.
Retain one selection-property subtree while frame presets are shown. Suspend opted-in descendant scopes after cleanup, cancel drafts before detachment can blur inputs, close portals, and release previews and pending resource work.
Track focused-element removal with VueUse so WebKit shortcuts resume after input teardown. Cover retained identity, hidden inactivity, binding rollback, async disposal, undo, popup reactivation and browser focus behavior.
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.
ARROW_LINES and ARROW_EQUILATERAL stroke caps were accepted by the schema
and round-tripped from .fig files, but the renderer mapped every cap to
Butt, so imported arrows lost their heads and arrows could not be drawn
locally.
Add a pure arrow-cap geometry module to scene-graph (open-endpoint
collection with per-vertex cap overrides, weight-scaled head geometry)
and draw heads in the stroke color for LINE nodes and open VECTOR
centerline strokes, including the dashed-centerline path. Fold the head
reach into strokeOverflow and the node picture margin so heads are not
cropped by visual bounds, caches, or culling. Round-trip per-vertex
stroke caps through the .fig vector style override table so one-ended
Figma arrows import correctly. Expose both caps in the stroke inspector
cap picker with localized labels, and cover the renderer with an
arrow-stroke-caps Playwright canvas snapshot.

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