physics: character controller (Jolt CharacterVirtual)
...
- CharacterControllerComponent: capsule params (radius/halfHeight, mass,
max slope, step height); entity origin = feet via shape offset
- CharacterController per-entity wrapper: gravity integration + grounded
clamp, ExtendedUpdate (sweep/slide + stick-to-floor + walk-stairs),
SetLinearVelocity/Jump/IsGrounded facade
- PhysicsWorld: SyncCharacters reconcile (create/rebuild on param
change, editor-drag teleport), UpdateCharacters after physics Update
(Jolt recommended order), writes back to Transform
- Inspector: params + grounded/velocity telemetry + jump debug button
- Serialization: params only, state rebuilt by reconcile

physics: joint constraints (fixed/hinge/ball)
...
- JointComponent: type, target UUID, per-body local anchors, hinge axis
+ angle limits (data only, zero Jolt deps)
- PhysicsWorld::SyncConstraints: create/remove/rebuild on snapshot
change; body rebuild contagion via invalidated-bits list; target
resolved lazily by UUID each sync (no two-pass load needed)
- Jolt FixedConstraint/HingeConstraint/PointConstraint in
LocalToBodyCOM space (anchors minus shape COM); fixed frames lock
creation-time relative pose; hinge axis aligned across bodies
- Inspector: Joint section with target entity name dropdown
- Serialization: Joint map with UUID target, as<T> fallbacks

physics: capsule/cylinder/compound collider shapes
...
- ColliderType + Capsule/Cylinder/Compound; CompoundChild list (Box/
Sphere/Capsule, local pos/quat, non-recursive)
- CreateBody: CapsuleShape/CylinderShape (ctor param orders differ) +
StaticCompoundShape; empty/failed compound falls back to Box
- BodyRecord caches radius/halfHeight/compound; SyncScene rebuilds on
change (per-collider param extraction)
- Inspector: combo entries + shape params + compound child list editor
- Serialization: new fields with as<T> fallback, compound seq round-trip

physics: rigid body drive API (force/impulse/torque/velocity)
...
PhysicsWorld facade methods addressed by entity bits via body records:
AddForce/AddImpulse/AddTorque (dynamic bodies only, auto-wake), Set/
GetLinearVelocity/SetAngularVelocity (dynamic + kinematic). Inspector
RigidBody block gains impulse debug controls for manual response tests.
Transient by design — nothing serialized.

editor camera: dedicated Scene-view camera decoupled from camera entities
...
EditorCamera (UE FEditorViewportClient semantics) owned by SceneRenderer:
own TransformComponent + reused Camera controller. BuildFrame dispatches
render source by display mode — editor form always renders from the
editor camera (usable in empty scenes), game form renders from the
scene's primary camera entity. AlignTo copies an entity pose into the
editor camera ("Align Viewport to Camera" button in Inspector). F focus
and viewport gizmo now follow the same dispatch. main.cpp stripped of
dangling sandbox camera/spinner state; onSceneLoaded hook removed.

feat: Gizmo local/world 空间切换 + Ctrl 吸附 + Inspector 轴色手输行
...
- GizmoState.localSpace（默认 local，模型轴旋转直观），T 键切换
Manipulate 的 LOCAL/WORLD 模式；无父层级两模式 world 矩阵同源，
decompose 写回链路不变
- Ctrl 按住吸附（UE Grid Snap 语义）：平移 0.25m / 旋转 15° /
缩放 0.1x；ImGuizmo 约定旋转 snap 单位为弧度
- 视口左上角 drawlist 叠加状态提示（Space/Snap，不占布局行）
- Inspector Transform 三行升级 UE 风轴色输入行（对齐 Gizmo 轴色）：
拖拽粗调 + Ctrl+Click 键入精确值

feat: HitProxy GPU 拾取 + UE 选中描边 + 编辑器拾取交互
...
- HitProxy 拾取：RG 管线渲染实体 id → host readback，点击帧
PickEntity 精确命中；拾取按视觉几何（Model 联合包围球射线求交），
与 Collider 解耦（UE/Unity 编辑器语义），命中打印实体名+碰撞体参数
- 选中描边（UE 语义）：SelectionMask pass（R8Unorm 完整投影轮廓，
无深度测试透墙可见）→ Outline pass（边缘检测 + alpha 叠加，
必须注册在 Tonemap 后）；edgeCut 贴视口边缘；widthPx=6 可调
- shader object 实证修复：VUID-08879 同程序 set layouts 超集一致、
VUID-10065 push block 4×float 平铺、新 pass 析构销毁 VkShaderEXT
- RG：SideEffect() 保活"产出无 RG 内消费者"的 pass 链
- Editor：层次面板点击选中、Inspector 姿态编辑、Stats 面板拾取信息
- 相机 Update 改 const（姿态写入 Transform 引用，Camera 本身无状态变更）

feat: ImGui docking Editor + 显示链/帧同步/输入语义重构
...
- App/editor: Hierarchy/Inspector/Viewport/Stats 四面板 + DockBuilder 默认布局，main.cpp 瘦身为场景搭建与生命周期
- 显示链: Tonemap→PresentTarget 经 ImGui::Image 呈现（零色偏），backbuffer 仅承载 ImGui；Direct/Viewport 双显示模式 + 面板分辨率上报
- 帧首同步 BeginFrameSync: resize/vsync/尺寸/模式意图统一帧首落定（修描述符悬垂）；修复 vsync 意图未落 swapchain 导致的每帧重建交换链
- 输入: Editor 每帧判定键盘/鼠标归属（打字让位、Viewport hover/focus 放行、Fullscreen 全放行）
- 材质: roughness 独立槽位 + 非 glTF 金属/粗糙贴图映射；透明队列 depthWrite=FALSE + translucent 独立 shader + scratch 清帧
- FBX: 非蒙皮网格烘焙节点链全局变换（Z-up 旋转/单位换算落顶点）
- Hierarchy 行 ImGui ID 以 UUID 作用域（重名不冲突、改名不丢选中）
