Backing installation advances the preview baseline but previously stamped old whole-scene pictures with the new scene version. Zooming outside backing coverage could replay deleted content and hide newly created shapes.
Discard mismatched pictures before advancing that baseline, preserving valid pictures. Cover scene, preview, page and font invalidation plus exact visible pixels through zoom reversals in retained and tiled renderers.
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.
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.
Compare analytic bounds numerically after verifying equivalent pivot compositions against the old implementation and an independent scalar oracle. Preserve exact renderer pixel comparisons and leave production transforms unchanged.
Skia analytic coverage depends on framebuffer dimensions as well as raster origin. Replay existing retained subtree pictures into the live viewport at settlement, while preserving overscan images for navigation. Keep settlement pending until the viewport pass and report the presentation path accurately. No additional viewport cache is allocated.
Preserve exact held/released assertions and cover odd/even/fractional pans at DPR 1, 1.25, 1.5 and 2. Verify native picture and backing identity reuse; update one pixel in the existing baseline only after proving equality with direct rendering.
Validation: full check, 735 scoped unit tests, and 58 targeted browser tests pass. The targeted set still excludes the previously classified paint-field-width baseline. An additional tiled large-blur test fails identically on parent d16400b3e, with byte-identical actual PNGs. Broader release acceptance remains separate.
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.
Compose announcement, typography, and paint workbenches with native linked components and editable effects. Preserve the original examples on a reference page.
Wait for the canvas and existing fonts before layout, fit demo pages on first visits, and preserve user viewports thereafter.
Publish committed history changes independently of scene mutations so menus observe history recorded after the final draw. Align the assets regression with the documented top-left default.
Reject unknown or incompatible references while the owning component definitions are available, including inherited component-set definitions. Keep nested component scopes separate.
Imported instance children arrive with componentId null, so every component edit re-cloned them and compounded per keystroke into runaway memory. Also fixes sibling inversion, extras jumping to front on sync, and stack overflow on self-referential components.
Sync: match unmatched children by name+type forward instead of cloning, guard self/cyclic sync via isDescendant, and keep unmapped extras at the end.
Import and paste: link children positionally at import time so renamed children stay linked. Clipboard paste is scoped to new instances only so existing instances are untouched.
* 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.
