…system Enable BabylonRenderHost to inject a real Engine while preserving default headless NullEngine behavior. Scene now uses right-handed coordinates to match three.js / glTF conventions. All ownership and dispose semantics preserved. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Mounting ThreeViewport while a selection is already in the store (engine switch back from Babylon, v1.0 B1) ran the initial syncSelection against an empty adapter — seedScene had not resolved yet — so gizmo/outline never appeared, and re-picking the same node is a store no-op that never re-fires the subscription. Latent pre-B1: every previous mount path had a null selection. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
IRenderHost契约（src/runtime/render-host.ts，B1 子集：mount / 渲染循环 / 相机 / resize / dispose）+isEngineEditingCapable能力门（B2/B3/B4 在一处放开能力）。BabylonAdapter构造可注入引擎（默认仍NullEngine，conformance/headless 零改动）+scene.useRightHandedSystem = true（对齐 three/glTF 右手坐标系，真渲染无 z 镜像）。BabylonRenderHost：真Engine+ArcRotateCamera（构图对齐 Three 编辑器相机 [4,3,4]/fov50°）+ 渲染循环；dispose 链 stop → camera →adapter.dispose()（engine 所有权在 adapter）。BabylonViewport：镜像 ThreeViewport mount-effect 约定（dep 仅 project id）；种场景/增量同步走新引擎中立纯函数diffSceneNodes（src/ui/viewport/scene-diff.ts）；单节点 sync 失败 warn-skip 不拉黑视口。Viewport包装组件 + 视口工具栏EngineTogglepill（useUIStore.viewportEngine会话态；切换强制退 play，防 play 残留卡死右栏）。isEngineEditingCapable禁用；hierarchy 选中与面板编辑保持可用且实时同步。ThreeViewport.tsx一行未改（「并行+定接口」策略；B2/B3 按 A1 spec §8 边界清单收敛）。Why
design/framework/architecture.md§7 v1.0（多运行时适配器；实时切换渲染引擎是平台战略目标）docs/superpowers/specs/2026-06-10-v1.0b1-render-host-design.md· Plan:docs/superpowers/plans/2026-06-10-v1.0b1-render-host.mdBabylonAdapterheadless 契约成立；B1 让用户第一次在实时视口看到第二引擎渲染同一场景。How to test
pnpm lint && pnpm typecheck && pnpm test（545 tests，含 conformance 双引擎 + 新增 scene-diff/render-host/BabylonViewport/Viewport/EngineToggle/禁用面用例）pnpm tauri dev视觉 smoke：已跑 headless 视觉 smoke（vite dev 前端 + headless Chrome CDP 驱动，diff 为纯前端故 surface 等价）：上述各项全过（滚轮缩放因 CDP quirk 未实测，orbit 已证）；两个已记录的非阻塞观感 gap（Babylon 底色比 Three 暗——Three OutputPass sRGB 提亮、Babylon 直写 raw；Babylon 光强偏亮）已入 roadmap B4。
