| ## 状态机脚本提示 | ||
| - 在状态上可添加 `StateMachineScript`（或自定义继承它的类），获得状态生命周期回调：`onStateEnter(stateInfo)`、`onStateUpdate(stateInfo, deltaTime)`、`onStateExit(stateInfo)`，可用于播放音效、特效、位移等。 |
There was a problem hiding this comment.
StateMachineScript does not receive stateInfo or deltaTime: its callbacks receive (animator, animatorState, layerIndex). Code following these documented signatures will treat the Animator as state info and cannot obtain the claimed update delta.

| - 多层混合时，基础层使用 Override，叠加层使用 Additive，设置合理权重，避免姿态冲突。 | ||
| - 对需要同步位移的动作使用脚本处理 RootMotion（读取动画位移并应用 Transform），避免在剪辑内硬编码。 | ||
| - 动画事件应做去抖/防重复处理，避免在高帧率下多次触发；回调逻辑保持轻量。 | ||
| - 大量 Animator 实例时复用控制器资源，减少重复加载；裁剪模式设置为 `CullingMode.CullUpdateTransforms` 在离屏时节省开销。 |

CullingMode.CullUpdateTransforms is not an Engine enum member; AnimatorCullingMode only provides None and Complete. Following this recommendation causes a compile failure instead of enabling off-screen animation culling.

Animator has play, crossFade, and crossFadeInFixedDuration, but no addAnimation method; that API belongs to Spine's animation state. This mixes the two animation APIs and will fail for standard Engine Animator users.

There was a problem hiding this comment.
defaultSceneRoot is a deprecated template property, so this attaches the cached template itself rather than a fresh model instance. That mutates the loaded resource's template hierarchy and prevents safely instantiating the same loaded glTF multiple times. Other locations where this applies: packages/galacean/skills/engine-knowledge/references/galacean-knowledge/Model/Model.md:21.

getInstanceMaterial(0) returns null when that slot is empty, so this direct dereference throws for a renderer without a slot-0 material.

packages/galacean/skills/engine-knowledge/SKILL.md:3、:18-26、:34-45，references/sbx-runtime-mistakes.md:57-86frontmatter 明确说不用于 Editor API/CLI workflow，但主流程又无条件要求
action:"create|update"、validated script-mutation、engine_api、editor_api、construction transaction、Builder VFS/manifest 路径；这些概念在@galacean/engine的依赖和源码中没有 owner，也不会随该 npm 包一起提供或版本锁定。它还要求场景、材质、网格、碰撞体和 UI 只能在 Editor/CLI 中预建，而当前公开契约明确提供Scene.createRootEntity、Entity.addComponent、new PBRMaterial、PrimitiveMesh.createCuboid；同一 PR 的 UI/Material/Mesh 示例也在直接走这些运行时创建路径。普通 npm 消费者触发该“标准” skill 后，会被引导去调用不存在的工具并放弃合法 Engine API。应保留 Engine skill 对运行时语义的说明，删除上述 mutation action、Editor payload、canonical VFS、Builder 物理映射和“必须预建”的策略；Editor/CLI/Builder 的 schema 与路径规则继续由各自版本化 skill/tool 直接产出，编排层按实际可用能力组合。若这些限制只服务 SBX/Game Factory，就把整段迁回该消费者的 skill，不要在 Engine 包内再维护协议镜像或适配层。

[P2] 重新验证并更新实验发布声明 — PR description 的 Impact / Validation
截至本轮读取，npm registry 中
0.0.0-experimental-2.0-skill.0虽然存在，但experimentaldist-tag 已指向0.0.0-experimental-2.0-migrate.7，并非正文所称“only the experimental tag points to this release”。引用的 workflow 也发布的是a6da0a76...，不是最终目标 HEAD。修完上述 P1 后，应对最终合并结果重新做 pack/安装验证；若仍要提供实验入口，发布新的不可变版本并移动 tag，同时把 PR 正文改成当前事实。 -
[P2] 让可复制代码片段遵守 Engine 的单行注释约定 —
references/galacean-knowledge/Animation/Example4.md:12、references/galacean-knowledge/Canvas/Example2.md:12、references/galacean-knowledge/Canvas/Example3.md:12、references/galacean-knowledge/Material/PBR.md:20、references/galacean-knowledge/PostProcess/Example2.md:16、references/galacean-knowledge/Scene/Example5.md:13、references/physics-setup.md:78这些
//注释以.或。收尾；它们会被 skill 直接作为脚本模板复制，需统一去掉尾句号。多行 TSDoc 才保留句号。
架构、熵增与测试治理
直接链路是：上游 Engine 源码/生成类型与外部 Editor、CLI、Builder schema 产出事实 → 本 PR 将事实手工转录进 npm skill → 下游 agent 读取后生成并挂载脚本。改动前，每类事实各有一个 owner；改动后，运行时事实从 1 份增至“源码 + 132 份手写投影”，外部构建协议也从各工具 owner 增至“工具 schema + Engine skill 镜像”，概念和校验路径净增且没有退场条件。应保留源码/生成类型和各外部 schema，删除两类镜像，使下游直接消费权威结果。
packages/galacean/package.json 的 files 列表仍是 npm 收录范围的合理唯一 owner，可保留；本 PR 没有新增运行时状态机或为旧测试保留 compatibility branch。测试侧的问题是 3738 行新知识没有任何随 PR 提交的 contract test，现有全绿 CI 只证明 Engine runtime 未被改坏，不能证明 skill 内容、路由和发布包正确。失效的手写示例应删除或按当前公开契约重写，不能为了让旧文档/fixture 继续成立而在生产代码中增加 legacy API、fallback、wrapper 或第二条转换/校验路径。

问题

[P1] 让 companion 包持有自己的运行时语义，删除根包中的 Spine / XR 镜像 —
packages/galacean/skills/engine-knowledge/SKILL.md:3、:8、:28-29，references/spine.md:3-8，references/xr.md:3-8，packages/galacean/package.json:29-35目标树里的
@galacean/engine@2.0.0-alpha.41只依赖 core/loader/math/rhi/shader，不选择或版本锁定 Spine、XR。XR 的源码、声明和 peer contract 实际由独立的@galacean/engine-xr@2.0.0-alpha.41/ WebXR 包持有；公开稳定版@galacean/engine-spine@4.2.8则来自另一仓库，peer 范围是>=1.5.0-0 || >=2.0.0-0，并直接依赖一个@esotericsoftware/spine-core。它没有这里第 7 行所述“version-neutral facade + 必须另导入一个 core backend + last registration wins”的组合契约。也就是说，根包版本既不能确定实际 companion，也无法让 companion 变化使这份投影失败；当前 CodeRabbit 对 attachment ownership 的 inline finding 已经是同一漂移机制的局部实例，本 review 不再重复那条文案修补。应保留各 companion 的源码、声明和运行时测试为唯一 owner：把
spine.md移到@galacean/engine-spine的实际发布边界，把xr.md移到@galacean/engine-xr/ WebXR 边界，并从根包的 inventory 和语句快照中删除它们。根 Skill 如需发现可选能力，只路由到已安装 companion 自带的 Skill；不要新增同步脚本、版本 fallback 或另一层协议镜像。 -
[P1] 在确认材质类型之前不要实例化并替换共享材质 —
packages/galacean/skills/engine-knowledge/references/runtime-recipes.md:83-87Renderer.getInstanceMaterial(0)不是只读查询：目标源码packages/core/src/Renderer.ts:183-192会在首次调用时 clone 当前材质，而:468-475随即调整引用计数、把 clone 写回槽位并标记为 instanced。当前 recipe 先调用它、再检查PBRMaterial，因此当槽位是共享的UnlitMaterial等非 PBR 材质时，函数虽然返回false，Renderer 已经脱离共享材质，后续对原材质的更新也不再传播。应保留 Renderer 的 material slot 为 ownership owner：先用无副作用的
getMaterial(0)验证类型，只有确认是 PBR 后才调用getInstanceMaterial(0)并修改 clone。增加行为回归测试，断言失败路径仍持有同一个材质对象且引用关系不变；仅编译代码块无法覆盖这一状态变化。 -
[P1] 查询与体积 recipe 不得隐式迁移 ColliderShape owner 或创建默认实体碰撞 —
packages/galacean/skills/engine-knowledge/references/runtime-recipes.md:29-32、:127-142enable3DPicking总是新建StaticCollider再addShape。但Collider.addShape在packages/core/src/physics/Collider.ts:68-75会先把已挂载的 shape 从旧 Collider 移除，所以调用者传入现有 DynamicCollider 的 shape 时，recipe 会把物理 owner 静默改成 StaticCollider；传入未挂载 shape 时，又因ColliderShape.isTrigger默认是false，把“启用 picking”升级成一个会阻挡刚体的 SimulationShape。局部 bloom 同样添加默认实体碰撞，而且 shape 默认还参与 scene query，可能截获原本面向场景对象的 raycast；下游PostProcessManager实际只读取 shape 的getClosestPoint，并不需要实体接触响应。应保留调用者已配置的 Collider/shape 为物理 owner：picking 复用已有可查询 Collider，缺失时让调用者显式选择 trigger、碰撞层和 query mask，不要迁移已有 shape；局部后处理体积应使用无接触响应的 trigger，并通过公开的专用 collision layer 与 ray mask 隔离查询。不要调用
@internal的isSceneQuery作为文档 API。补充公开路径行为测试，至少验证 picking 不改变既有 Collider 归属、两个 helper 不阻挡动态刚体、局部 volume 不抢占目标 raycast。
架构、熵增与测试治理
直接链路是：上游 Engine/companion 源码、生成声明和运行时测试产出事实与 ownership 契约 → 本 PR 将不可从类型表达的语义投影进 npm Skill → 下游 agent 组合 recipe 并创建 Renderer、Material、Collider 和 Script。相对上轮，132 份百科、宿主协议和旧模板被删除，核心事实 owner、概念数和兼容分支都显著净减；packages/galacean/package.json 的 files 仍是发布收录的合理 owner，本 PR 也没有给生产代码增加 legacy fallback。
尚未闭环的熵增有两处：其一，Spine/XR 语义仍各多出一份由根包持有、却不受 companion 版本约束的真相；其二，6 个 recipe 新增了跨 API 的控制流，但其中两类 helper 把材质和物理状态决策隐藏在看似局部的操作里，将复杂度转移给下游。应保留 companion 包、Renderer material slot 和调用者配置的 Collider/shape 为 owner，删除根包镜像并让 recipe 机械遵循这些 owner，而不是再加同步层或平行状态。
当前 inventory/link/npm-pack 测试能验证分发契约，recipe type-check 能验证 symbol/signature，均应保留；但 EngineKnowledgeSkill.test.ts:93-106 的 toContain 只锁住句子，不能证明语义，编译测试也观察不到 clone、引用计数、Collider 迁移、接触响应或 raycast 选择。现有 CI 全绿因此不覆盖上述 P1。应在各权威 owner 的测试边界补行为断言，并删除或迁移 companion 的根包语句 fixture；不得为了维持旧文字测试，在生产代码中加入 compatibility branch、wrapper、镜像状态或第二条转换/校验路径。

[P1] 让 Spine / XR companion 持有自己的 Skill，删除根包中的语义镜像 —
packages/galacean/skills/engine-knowledge/SKILL.md:3,8,28-29，references/spine.md:3-8，references/xr.md:3-26，packages/galacean/package.json:28-35本轮只修正了 Spine attachment 的 instance/shared 分界，没有改变发布 owner。目标树的
@galacean/engine@2.0.0-alpha.41只依赖 core/loader/math/rhi/shader，根 contract test 也只解析它自己的types/index.d.ts。XR2.0.0-alpha.41的精确 peer、源码、声明和运行时测试实际由@galacean/engine-xr持有；公开@galacean/engine-spine@4.2.8则使用宽泛 Engine peer 并直接依赖、导出@esotericsoftware/spine-core，没有第 7 行所述的 facade/backend registry。该 registry 只存在于0.0.0-experimental-2.0-migrate.7，而它要求同名 experimental Engine peer，并不匹配当前目标包。因此根 Skill 可以在 companion 未安装、版本不同或实现已变化时继续通过全部测试，却向 alpha.41 消费者投影另一条发布线的事实。应保留各 companion 的源码、生成声明和运行时测试为唯一 owner：把 Spine 语义及 Skill 发布移回
@galacean/engine-spine，把 XR 语义及 Skill 发布移回@galacean/engine-xr/ WebXR；根包只做已安装 companion 的发现路由，并从根 inventory、tarball 断言和 reference graph 删除这两份镜像。不要增加同步脚本、版本 fallback 或第二层协议适配。 -
[P1] 让
loadScene的返回 Promise 持有完整的销毁与激活事务 —packages/core/src/SceneManager.ts:90,93-104新 TSDoc 把 “销毁所有 managed Scenes 后再加入 loaded Scene” 提升为公开契约，但实现对
SafeLoopArray.getArray()返回的 live array 做正向遍历。正常的 Promise 帧外完成路径中，Scene.destroy()会立即经_onDestroy -> removeScene -> splice缩短同一个数组；已有两个 Scene 时，第一次销毁后scenes[1]已是undefined，下一次.destroy()抛错，loaded Scene 不会被加入且旧状态只销毁了一部分。这里又丢弃了副作用.then(...)产生的子 Promise、返回原始加载 Promise，所以调用者仍可能观察到成功 resolve，而内部异常无法沿公开返回值传播。应让
SceneManager.loadScene成为唯一事务 owner：对稳定快照遍历或反向销毁，并返回包含销毁、addScene和return scene的 chainedAssetPromise。补一个公开路径回归测试，至少从两个 managed Scenes 出发，断言 await 完成时旧 Scene 全部销毁、新 Scene 已受管，且事务错误会 reject；不要用文案弱化来掩盖这条已明确的 API 契约。 -
[P1] 让声明编译 contract test 在完整 CI 中可完成 —
packages/galacean/tests/EngineKnowledgeSkill.test.ts:70-112目标 HEAD 的
codecovjob97901395478不是上传告警：其Teststep 中其余 1683 个测试全部通过，唯一本 PR 的 “type-checks every retained runtime recipe” 在 Vitest 默认5000ms达到超时并令 required job 失败。PR 正文中的 focused “3 passed” 因此不能代表最终合并门禁。保留声明编译这一有效校验，但为该集成型测试设置经完整套件验证的显式超时，或隔离/优化 TypeScript program 构建，再重跑最终 CI；不要跳过或降级这条 contract test。
-
[P2] 为本轮三条 recipe 修复提交可反向证伪的行为测试 —
packages/galacean/tests/EngineKnowledgeSkill.test.ts:30-135，references/runtime-recipes.md:5-32,70-100,125-159当前测试只验证 reference 可达、TypeScript 可编译和 tarball 收录。把这三段 recipe 单独退回
5171f901的“判型前 clone、创建/迁移 Collider、创建默认实体 volume”实现后，它们仍然全部可编译，现有测试不会失败；这正是上一轮 P1 已在全绿测试下存在的原因。固定句子快照已经删除，应继续保持删除，但需从 Markdown 中的实际代码块走公开 API 行为场景：断言 normal-map 失败与异步换材质路径保持 slot 对象不变，picking 不新增或迁移 shape，local bloom 不新增/重配 Collider 且失败路径不打开 Camera。不要复制一份 helper、戳私有字段，或为旧 fixture 在生产代码中保留兼容分支。
架构、熵增与测试治理
直接链路是：上游 Engine core/loader 与各 companion 的源码、生成声明和运行时测试拥有 API、状态和生命周期事实 → TSDoc 与随包 Skill 投影不可由类型表达的语义 → 下游 agent 组合 recipe，最终写入 Renderer、Material、Scene、Collider 和 PostProcess。packages/galacean/package.json 的 files 仍是根包发布收录的合理 owner。
相对 5171f901，本轮把材质 slot 归还 Renderer、把 collider/shape/物理策略归还调用者，并把 clone、scene load 和 shape move 的单 API 事实放回源 TSDoc；同时删除 expectedMarkdownFiles、heading 列表和固定句子快照，改从真实文件图机械派生 reference 与 tarball inventory。owner、隐藏写入、派生测试状态和固定转换路径总体净减，也没有给生产代码新增 legacy fallback、wrapper、镜像状态或测试兼容分支。
剩余熵增集中在两处：根包仍替 Spine/XR 各持有一份不受其发布边界验证的事实；loadScene 又把“加载已完成”和“销毁/激活已完成”分成返回 Promise 与被丢弃子 Promise 两条完成路径。应分别收回 companion owner，并让一个 chained Promise 拥有 Scene 事务。测试侧，通用 link/type/pack 校验值得保留，但当前编译测试在最终 CI 中不可用且观察不到副作用；应按新公开契约补行为反向测试，已删除的文案 fixture 不应恢复，更不得为它们增加生产 compatibility path。

[P1] 让 Spine / XR companion 持有自己的 Skill，删除根包中的语义镜像 —
packages/galacean/skills/engine-knowledge/SKILL.md:3,8,28-29，references/spine.md:3-8，references/xr.md:3-26，packages/galacean/package.json:18-35本轮两个 commit 只迁移校验路径，没有改变发布 owner。目标树的
@galacean/engine@2.0.0-alpha.41仍只依赖 core / loader / math / rhi / shader；当前 base 合并结果虽把 workspace 版本推进到 alpha.42，也没有增加任何 companion 依赖或 peer。根校验又只把 recipe 映射到根包的types/index.d.ts，所以已安装 companion 缺失、版本变化或实现漂移都不能让spine.md/xr.md失败。相对地，XR 的精确 peer、源码、声明和运行时测试由@galacean/engine-xr/ WebXR 持有；公开@galacean/engine-spine@4.2.8使用宽泛 Engine peer 并直接依赖@esotericsoftware/spine-core，并没有第 7 行描述的 facade / backend registry。该 registry 属于要求同名 experimental Engine peer 的另一条发布线。应保留各 companion 的源码、生成声明和运行时测试为唯一 owner：从根 Skill 的 frontmatter、reference graph 和发布内容中删除
spine.md、xr.md及两条路由，分别由 Spine 与 XR companion 在自己的版本边界发布 Skill。不要增加同步脚本、版本 fallback 或第二层协议适配。 -
[P1] 让
loadScene的返回 Promise 持有完整的销毁与激活事务 —packages/core/src/SceneManager.ts:87-104新 TSDoc 明确承诺“销毁所有 managed Scenes 后再加入 loaded Scene”，但实现仍遍历
SafeLoopArray.getArray()返回的 live array。加载回调在正常 Promise 帧外执行时，Scene.destroy()会立即经Scene._onDestroy -> removeScene -> splice缩短同一数组；已有两个 Scene 时，第一次销毁后旧第二项移到索引 0，下一轮访问scenes[1].destroy()会对undefined调用并中断，留下一个旧 Scene 且不加入新 Scene。与此同时，代码丢弃了.then(...)产生的子AssetPromise，却返回原始加载 Promise，因此调用者仍可观察到成功 resolve，而销毁或addScene的异常只进入无人持有的子链。应让
SceneManager.loadScene成为唯一事务 owner：从稳定快照反向销毁旧 Scene，并直接返回包含销毁、addScene和return scene的 chainedAssetPromise，删除“原始加载完成”这条平行完成状态。补公开路径回归测试，至少从两个 managed Scenes 出发，断言 await 完成时旧 Scene 全部销毁、新 Scene 已受管，且事务异常会 reject。 -
[P2] 为三条 recipe 修复提交可反向证伪的持久行为测试 —

5171f901的“判型前 clone、创建或迁移 Collider、创建默认实体 volume”实现后，当前 link / type / pack 校验仍会全部通过；PR 正文所列 independent forward tests 没有进入仓库，也不能作为后续合并门禁。应从 Markdown 中的实际代码块走公开 API 行为场景，断言 normal-map 失败与异步换材质路径保持 slot 对象不变，picking 不新增或迁移 shape，local bloom 不新增或重配 Collider 且失败路径不打开 Camera。不要复制一份 helper、戳私有字段，或为旧 fixture 在生产代码中保留 compatibility branch。
架构、熵增与测试治理
直接链路是：上游 Engine core / loader 与各 companion 的源码、生成声明和运行时测试拥有 API、状态和生命周期事实 → 源 TSDoc 与随包 Skill 投影类型无法表达的语义 → 下游 agent 组合 recipe，最终写入 Renderer、Material、Scene、Collider 和 PostProcess；packages/galacean/package.json 的 files 仍是根 Skill 发布收录的合理 owner。
相对 d5d977f，本轮把声明编译从 coverage 测试迁到 b:types，校验 owner 仍只有一个，且由完整 build 直接消费；Vitest 只保留 reference graph 与 tarball 边界，codecov.yml 也没有形成 production fallback、legacy wrapper 或第三份验证状态。这部分熵净减，最终 CI 已证明迁移后的路径可用。
剩余熵增没有变化：根包仍替两个未由它版本锁定的 companion 各持有一份语义真相；loadScene 仍同时存在原始加载完成与被丢弃事务完成两条状态。应分别把事实收回 companion owner，并让一个 chained Promise 独占 Scene 事务。测试侧已删除的固定句子 fixture 和旧行为测试没有恢复，也没有为了旧测试增加生产兼容分支；但三条跨 API 副作用仍缺少反向守卫，需按当前公开契约补行为测试。

[P2] 让 PR 正文描述最终目标树和最终 CI — PR description 第 5-7、18、26、35-36 行
300a3696638666已删除 Spine / XR 两份 reference，并把SceneManager.ts完整恢复为 base；最终 Skill 是 7 份 reference，focused contract 文件也已从 2 个测试增至 5 个。但正文仍声称新增SceneManager.loadScene文档、9 份 reference、Spine / XR 知识，并记录 “2 passed”，自动摘要也继续列出 Spine / XR。这样人工 Reviewer 和后续 release note 读取的是上一轮范围，而不是待合并产物。应保留目标树和最终 CI 为权威 owner：从正文删除
loadScene、Spine / XR 与“9 份”陈述，改为当前 7 份 reference，并把 focused test 数更新为 5；不要为了让旧正文成立而把已删除的 companion 镜像或契约改动加回代码。
架构、熵增与测试治理
直接链路是：上游 Engine core / loader 源码与生成声明拥有 API shape 和单 API 行为 → 源 TSDoc 与根包随版本发布的 7 份 Skill reference 投影类型无法表达的语义 → packages/galacean/package.json 决定发布收录 → 下游 agent 读取 recipe，最终写入 Renderer、Material、Collider、PostProcess、Scene 等 runtime owner。
相对 72e42d，本轮删除了根包持有的 2 份 companion 事实和 1 个 loadScene 契约增量，owner 与概念数净减；新增的 3 个行为测试从实际 Markdown code block 机械取源，只增加观察路径，没有形成第三份 recipe、平行转换、legacy fallback、wrapper 或生产兼容分支。声明编译、reference graph、npm pack 和行为测试分别守不同边界，没有重复争夺同一验证结果的 ownership。
当前唯一漂移位于 PR 正文这一人工投影；按目标树机械校准或删除失效陈述即可，不应把复杂度转回生产代码或恢复已经退场的测试与 companion 路径。

结论
本轮以 ec2e64526e26a866db7b40697e78b73145f0bbe5 为目标 HEAD，审查了上次 300a3696638666f4190b37982446952199e5bc02 之后的 1 个线性 commit，并回看 merge-base bd34daa45612af8b402cd3be916ff181f21ae742 到当前 18 个文件的最终 diff；同时核对了 npm 发布边界、合并结果 5e28b24ab42d70e4cd8083a04f80679a5c22845c 和全部 12 个成功 checks。最新 commit 修正了 Spine runtime / loader 的局部事实，并恢复 Spine、XR 两份 reference；XR 有同仓同版本的 exact peer 约束，可以随 Engine release 对齐，但 Spine 仍被没有依赖或版本约束的根包代持，因此有 1 个 P1，另有 1 个 PR 元信息 P2，阻塞级别为 P1。PR 已于 2026-08-26 06:41:49Z 合并；实际 review 动作：REQUEST_CHANGES（事后阻塞记录）；目标 HEAD 为 ec2e64526e26a866db7b40697e78b73145f0bbe5。
自动 CR 不替代人工 Reviewer 的合入门禁；由于合并已经发生，需要维护者在后续发布前决定回退或以修复提交闭环。
已关闭问题清单
- 核心 API 百科、宿主协议、实验发布声明和单行注释：保持关闭。 最终树没有恢复 API catalog、SBX / Editor / CLI / Builder 镜像、旧实验发布断言或违规示例注释。
- 材质与 Collider 隐藏写入及其行为守卫：保持关闭。 normal-map、picking、local bloom recipe 仍保留 Renderer material slot 与调用者 Collider / shape 为 owner；5 个 focused contract / behavior case 继续直接消费 Markdown 中的实际代码块，没有恢复旧 fixture 或生产 compatibility path。
- 声明编译校验的完整 CI 超时：保持关闭。
validate:engine-knowledge仍由唯一的b:types路径执行；目标 CI 的三平台 build、codecov 和 4 组 e2e 全绿。 loadScene新增契约与既有事务不一致：保持关闭。 目标 HEAD 与 merge-base 均未改SceneManager.ts，本 PR 没有重新扩大该公开契约；PR 正文的残留陈述单列在下方。- Spine registry 局部事实和 active attachment ownership：已关闭。
ec2e64526e26已把旧 facade / global backend 说法改为当前@galacean/engine-spine@4.2.8实际的直接spine-core4.2 依赖与 re-export，并正确列出.json/.bin/.skelloader；Slot active selection 与共享 Attachment 的边界仍准确。 - XR 聚合边界：不再作为 finding。 目标树的
@galacean/engine-xr@2.0.0-alpha.41对根包使用 exact peer，且二者同仓发布；GitHub 合并结果也同步落在 alpha.42。其 reference 与该 release boundary 对齐，不与下方独立发布的 Spine 情况机械并列。

[P1] 让
@galacean/engine-spine持有 Spine Skill，删除根包中的外部语义镜像 —packages/galacean/skills/engine-knowledge/SKILL.md:3,8,28，references/spine.md:3-28，packages/galacean/package.json:18-35ec2e64526e26重新加入了300a3696638666 fix(engine): align knowledge skill ownership删除的 Spine route 和 28 行行为投影。目标根包只依赖 core / loader / math / rhi / shader，也没有 Spine optional peer；实际@galacean/engine-spine@4.2.8来自另一仓库，peer 是宽泛的>=1.5.0-0 || >=2.0.0-0。因此根包版本不能确定用户安装的 Spine 版本，而根校验只编译根包 recipe 对types/index.d.ts，没有依赖或执行这份纯 prose companion reference。兼容的旧版或未来新版 Spine 改变 loader、生命周期或资源 ownership 时，根包 build 仍会全绿，下游 agent 却继续读取当前静态语义。应保留
@galacean/engine-spine的源码、声明、运行时测试和随该包发布的 Skill 为唯一 owner：把spine.md迁到 companion 发布边界，并从根 Skill 的 frontmatter、正文和 reference graph 删除 Spine；安装了 companion 的下游直接发现其 Skill。不要增加同步脚本、版本 fallback、wrapper 或第二份校验路径。 -
[P2] 让 PR 正文只记录最终目标树和最终测试结果 — PR description 第 5、18、26 行
最终 diff 没有
SceneManager.loadScene改动，focused 文件实际包含 5 个测试而不是 “2 passed”；第 18 行的 “Spine runtime knowledge stays version-matched” 也与上述独立发布边界不符。这会让合并后的历史记录和 release note 描述一个不存在的契约及错误验证结果。应以目标树和最终 CI 为权威 owner：删除
loadScene陈述，把 focused count 更新为 5，并随上方 ownership 修复删除 version-matched Spine 声明、把 reference 数校准为 8。不要为了让旧正文成立而恢复已撤回的 runtime 契约，或在生产代码与测试中保留旧路径。
架构、熵增与测试治理
直接链路是：Engine core / loader 与同仓 exact-peer XR 源码、声明和运行时测试拥有各自版本事实；独立的 @galacean/engine-spine 发布边界拥有 Spine 事实 → 随包 Skill 投影类型无法表达的组合语义 → packages/galacean/package.json 决定根 Skill 的 npm 收录 → 下游 agent 读取 reference，最终写入 Renderer、Material、Collider、PostProcess、XR Camera 或 Spine 实例等 runtime owner。
相对 300a369，本轮没有增加 runtime 状态机、转换、compat 分支或 wrapper；XR reference 由同仓 exact-peer release 约束，可接受。Spine 则从 0 份根包外部事实重新增加为 1 份无法由根 package build 证伪的手工镜像，owner 和概念数净增。应保留 companion package 为 owner并删除根镜像，使数据流回到“已安装 companion 的声明 / Skill → 下游”。
测试侧，reference graph、npm pack、根声明编译和三条 recipe 行为测试仍分别守住有效边界，失效 fixture 没有恢复，也没有为旧测试加入生产兼容逻辑；但它们机械收录 spine.md 并不能验证外部包语义。CI 全绿因此不关闭上述发布 ownership 问题，正确收口是迁移并删除镜像，而不是再叠同步校验。

What changed
engine-knowledgeSkill with@galacean/engine.SKILL.mdsmall and route only to the relevant reference.SceneManager.loadScene,Entity.clone, prefab/glTF instantiation, andCollider.addShape.Why
Runtime semantics should travel with the matching Engine version without creating a second API authority. Single-API behavior belongs in source documentation; the Skill retains only non-obvious composition knowledge that changes construction decisions.
