三轮 review @ b413f41bb（线性追加 1 commit，--comment）
相对二轮的变化：二轮我审的 tip
b474e58f5之上线性追加了b413f41bb refactor(physics): drop redundant target normalization（compare报ahead 1 / behind 0，无 force-push）。该 commit 删除了move()里的 JS 侧 quat 归一化——两处 rotation 入口从.normalized ? 直传 : tempRotation.copyFrom().normalize()改回裸转发setKinematicTarget(pos, rot)，并删除对应的normalizes non-unit kinematic targets...白盒测试 + 未用的Quaternionimport（净-10/+3源、-29/+1测试）。
二轮结论的自我修正
二轮我把这套 JS 侧归一化判为"正确"。本轮基于 PhysX 真源核对后确认：作者删得对，我二轮的"正确"评价过誉了——那段归一化是重复 PhysX 自身工作的冗余防御代码。 这正是"前几轮 review 可能都在错方向上加固"的一个实例，据实修正。
删除安全性核对（回到构建 WASM 的 PhysX 真源，逐条证伪 PR 描述三条论断）
PR 描述称"bundled runtime 是 Release build、isSane() 被编译掉、setKinematicTarget 无条件 getNormalized()"。不信描述，直接读构建 physx.release.wasm 的 C++ 真源（/Users/chenmo/Code/Galacean/physX.js）：
getNormalized()无条件执行 —NpRigidDynamic.cpp:144setKinematicTargetInternal(destination.getNormalized());在任何#ifguard 之外，release/checked 都跑。getNormalized()（PxQuat.h）按真实 magnitude 除，对任意有限非零 quat 产出正规单位四元数。- Release 关掉
PX_CHECKED—emscripten/CMakeLists.txtRELEASE 编译定义仅NDEBUG;PX_SUPPORT_PVD=0，不含PX_CHECKED→PX_CHECK_AND_RETURN(destination.isSane(), ...)（NpRigidDynamic.cpp:130）经CmPhysXCommon.h:68展开为空。所以isSane()的拒绝不会触发。⚠️ 值得一提：isSane()（PxQuat.h:142-146）不止查有限性，还查|magnitude−1| < 1e-2——它本会拒非单位 quat；只有在 release 把它编译掉后，非单位 quat 才得以走到 :144 被getNormalized()收拾。两个条件缺一，删除都不安全，此处恰好都成立。 - binding 层裸转发 —
ActorBinding.h:112-115emscripten glue 把(pos,rot)直接包PxTransform转发原生调用，无任何预归一化/校验，完全依赖原生 :144。 physx.release.wasm是唯一默认产物（libs/只有 release + release.simd，无 debug/checked 变体；build.sh只build release）。
结论：用户传入的有限非零非单位 quat → 原生 getNormalized() 修正 → 旋转正确，JS 侧归一化确属冗余。退化零 quat（(0,0,0,0)→NaN）old/new 都不防（旧 Quaternion.normalize 有零守卫会原样透传零 quat，PhysX getNormalized 反而产 NaN），但零 quat 作为旋转 target 本就无意义、非本 PR 引入的回归、非现实输入。
剩余路径核对（均通过）
move()三路径（PhysXDynamicCollider.ts:230-251）：both-args / rotation-only 现裸传用户 quat（原生归一化兜底，安全）；position-only 复用getWorldTransform→getGlobalPose()读回值（PhysX 存的即单位 quat，无需归一化）。逻辑自洽。- 删测正确、无孤儿：被删测试测的正是被删的 JS 归一化行为，代码与测试同删是对的；剩下的两个 CCD 契约测试（
defers swept CCD across kinematic transitions/switches between swept and speculative CCD...）本轮未动、仍真守 mutual-exclusivity 与延迟 CCD 的原生边界。删掉的Quaternionimport 同步清理干净。 - CCD 状态机（二轮已审部分）本轮零改动，无需复审。CI 全绿（
codecov真跑 vitest / e2e 4/4 / build ×3）。
与 #3040 / #3025 的关系
按 diff 核对：本 PR 两文件（PhysXDynamicCollider.ts / DynamicCollider.test.ts）与 #3040（clone 重构，packages/core/*，无 physics-physx）、#3025（fix/physics-shaderlab-split，改 PhysXPhysicsScene.ts/Collision.ts 等，不含 PhysXDynamicCollider.ts）零文件交叉，无 merge-order 依赖。PR 描述的独立性声明属实。
问题
- [P3]（二轮遗留，部分闭环）
PhysXDynamicCollider.ts:185,265— 二轮标的 4 条带句号单行//注释里，move()的 2 条随归一化删除已消失；剩 2 条仍带句末句号（...eKINEMATIC is raised./...at the same time.）。本包惯例单行//不加句号（对照PhysXPhysics.ts:286,290、PhysXCharacterController.ts:91,93）。建议顺手去掉两处句号。非阻塞。
结论
无 P0/P1/P2，--comment。 本轮 delta 是一次正确的冗余消除——JS 侧 quat 归一化经 PhysX 真源核对确属重复原生 getNormalized() 的防御代码，删除安全（两个必要条件"getNormalized 无条件 + release 关 PX_CHECKED"均成立）、测试同步删除无孤儿、剩余 CCD 契约测试仍守得住、CI 全绿。仅一条二轮遗留的注释句号 P3 未闭环。

四轮 review @ d98ffe1ee（线性追加 1 commit，--comment）
相对三轮的变化：三轮我审的 tip
b413f41bb之上线性追加了唯一一个 commitd98ffe1ee style(physics): align inline comments（compare报ahead 1 / behind 0，无 force-push），仅动PhysXDynamicCollider.ts一个文件、净-0/+0行、纯改注释文本。
唯一 delta：三轮遗留 P3 已闭环
三轮我标的最后一条 [P3] 是 PhysXDynamicCollider.ts:185,265 两条单行 // 注释带句末句号，偏离本包惯例（对照 PhysXPhysics.ts:286,290、PhysXCharacterController.ts:91,93 单行 // 均不加句号）。本 commit 逐字采纳：
- // PhysX rejects swept CCD when eKINEMATIC is raised.
+ // PhysX rejects swept CCD when eKINEMATIC is raised
- // PhysX rejects enabling swept and speculative CCD at the same time.
+ // PhysX rejects enabling swept and speculative CCD at the same time核对当前 tree（d98ffe1ee）：全文件现仅剩这 2 条 // 注释，无任何 // 注释以句号结尾，与包内惯例对齐。P3 闭环。
逻辑零改动、无需复审
本 commit 不触碰任何代码路径——CCD 状态机（kinematic × swept 互斥、swept × speculative 互斥、_applyCollisionDetectionFlags 先关旧族再开新族的写序）、move() 三路径裸转发 + native getNormalized() 兜底、两个 CCD 契约测试均与三轮 approve 时逐字一致。三轮已逐条闭环的实质问题本轮不重审。CI 全绿（build ×3 / codecov 真跑 vitest / e2e 4/4 / lint）。
结论
无 P0/P1/P2/P3，--comment。 本轮 delta 是三轮遗留注释句号 P3 的纯风格闭环，逐字采纳、无任何逻辑改动、无新增问题。此前四轮累积的所有 finding 现已全部关闭，PR 从 review 视角处于可合状态（base 正确落在 dev/2.0、与 #3025/#3040/#3042 零文件交叉、无 merge-order 依赖）。

packages/design/src/physics/IDynamicCollider.ts:120-124/ PR 正文 — 最终代码已经把已发布的@galacean/engine-designbackend SPI 从setIsKinematic+setCollisionDetectionMode替换为唯一的setMotionState；外部 physics provider 升级后必须迁移，否则新 Core 会调用不存在的方法。当前 PR 正文仍描述已删除的 PhysX_isKinematicmirror、kinematic 下 swept 请求降为Discrete、改动仅限 PhysX adapter/两个文件，这与最终实现“Core 传权威状态对、PhysX 将 kinematic swept 机械映射为 speculative、四文件含 design 契约变更”相反。请保留setMotionState作为唯一 owner，不要恢复旧 wrapper/fallback；更新 PR 的 Solution/Scope/迁移说明，并在该方法 TSDoc 中写明实现者必须基于这对权威值完成合法 native 过渡、不得产生非法中间 flags。
架构、熵增与测试治理
- 上游权威 owner 仍是 Core
DynamicCollider._isKinematic与_collisionDetectionMode；两处公开 setter 和 clone_syncNative都把同一状态快照交给setMotionState。下游权威 owner 是 PhysX actor flags；adapter 先清 swept/friction/speculative，再切eKINEMATIC，最后只启用合法 CCD family。非凸 triangle mesh 仍在super._syncNative()附着前完成 kinematic 写入，原有前置条件未被回退。 - 相比最终 base，状态数量不变，backend 写协议由 2 个入口收口为 1 个，CCD/kinematic 转换由两条独立路径合并为一条；相比上轮 PR 方案还删除了 PhysX
_isKinematic镜像与_applyCollisionDetectionFlags第二转换层。净结果是少一个 mirror、少一个平行状态机、没有 compatibility branch 或第三份真相。kinematic 下将Continuous/ContinuousDynamic请求映射为 speculative 与 UnitySetPxActorCCDFlag(actor, ccd, kinematic)的同类 PhysX 边界策略一致。 - 新测试从 Core 公开 setter 驱动，断言 native flag 最终值及 disable-before-enable 写序；回退到 base 的分离 setter 后会在 kinematic speculative 结果与写序上失败，属于有效反向见证。历史 JavaScript 归一化测试已随冗余生产路径删除，没有 fixture/mock/snapshot 残留，也没有为了旧测试保留 legacy 路径。目标 HEAD 的 lint、三平台 build、四组 e2e 与实际 codecov 测试 job 均成功，patch 覆盖为 100%；

Pull request overview
This PR fixes invalid intermediate PhysX rigid-body flag combinations that could occur when toggling isKinematic and collisionDetectionMode via separate native adapter calls, by introducing a single atomic native boundary for “motion state” changes and updating tests to cover these transitions and the kinematic CCD fallback behavior.
Changes:
- Replaces separate native calls (
setIsKinematic,setCollisionDetectionMode) with a unifiedsetMotionState(isKinematic, collisionDetectionMode)boundary to avoid illegal intermediate PhysX states. - Updates Core
DynamicColliderto drive motion state updates throughsetMotionStateand to apply motion state before shape/native sync (to support non-convex mesh attachment ordering). - Adds/extends tests to assert correct flag transition ordering and to validate kinematic non-discrete CCD fallback behavior (speculative CCD).

Problem
PhysX 4.1.1 validates rigid-body flags on every native write. Kinematic bodies cannot use sweep-based CCD, and sweep-based and speculative CCD cannot be enabled together. Updating
isKinematicandcollisionDetectionModethrough separate adapter calls therefore exposed illegal intermediate native states and required the adapter to mirror Core state.The actor must also be made kinematic before attaching a non-convex triangle mesh, so motion state is part of native collider initialization order rather than an independent flag toggle.
Solution
setIsKinematicandsetCollisionDetectionModewith one backend boundary:setMotionState(isKinematic, collisionDetectionMode).eKINEMATIC, then enable the selected legal family.Discreterequest to speculative CCD while kinematic. Core retains the requested mode, so switching back to dynamic restores its sweep-based mode.super._syncNative()so non-convex triangle meshes are attached only after the native actor is kinematic.Effective PhysX mapping:
DiscreteContinuous/ContinuousDynamicContinuousSpeculativeDiscreteTests
Continuousbody through a swept-CCD dynamic body. The fallback prevents tunneling and produces the same position and velocity as an otherwise identical explicitContinuousSpeculativerun.Verification
