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.
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.
