 ## Tasks
 
-- [ ] Scaffold `packages/editor` (`@repo/editor`) as a green package shell using `pnpm turbo gen core-package` output as the baseline shape (adapted for a non-core package): tsconfig `rootDir: "."`, vitest config with `@` alias, conformance ESLint rules active; React 19; React Flow + zustand wired against the pre-approved `platform-retrofit` traces.
-- [ ] Add the canvas-protocol client (pinned `targetOrigin` both directions; `runtime.ready`, geometry reports, click-target selection round-trip) unit-tested against a scripted agent double + the minimal zustand store holding registry + selection only.
-- [ ] Add the React Flow board shell + one iframe frame node hosting the adapter origin + editor-side selection overlay rendered from agent-reported geometry; the frame renders a single Element (discovered component, default props) requested via `render-frame`; pan/zoom stays editor-side (< 16 ms/frame, no protocol round-trip on drag); stories + component tests for board/frame/overlay.
