架构、熵增与测试治理
- 上游
Entity.addComponent与Entity._setActiveComponents是仅有的两个激活调用入口；下游Component仍独占_awoken/_phasedActiveInScene/_phasedActive的写入和生命周期顺序，Script、Renderer、Camera 等只消费虚钩子。包内componentSetActiveSymbol 只把这条非虚调用收回Componentowner，没有把状态或判断转移给Entity。 - 改动前后逻辑 owner、三份阶段状态、状态转换、校验和虚钩子协议数量均不增加：字符串键替换为一个包内 Symbol，未新增 mirror/cache/wrapper/flag/fallback、兼容分支或逐调用分配。完整目标树只有一个定义和两个调用点；旧
_setActive路径、生命周期 Symbol 中间方案及相关测试改写均无残留。Symbol 和方法均受@internal + stripInternal约束，且未从 core index 导出，公开声明未产生第二份协议。 - 新测试从公开链路
addComponent → addChild → onAwake/onEnable触发，并同时覆盖两个调用入口；把任一入口恢复为字符串调用都会执行用户_setActivehelper 并复现原始异常，具备反向证伪能力。测试没有戳内部状态，也没有引入失效 fixture/mock/snapshot；生产代码没有为旧测试保留 compatibility path。
需要从可继承类型的内部协议边界审视根因
从第一性原理看，真正的矛盾是：

[P1] 保留完整声明，但恢复不可覆写的激活 owner（
packages/core/src/Component.ts:113，packages/core/src/Entity.ts:259,698，提交12fc242ccf079de815492c77b894209407fb36c7）。作者回复把支持边界收窄到“重新参与类型检查的 TypeScript consumer”，但 issue #3103 的 Expected behavior 明确要求内部非虚激活操作不能被 consumer member 覆写，PR 仍声明Fixes #3103。当前普通字符串动态分发只能拦住签名或可见性不兼容且重新编译的 TypeScript 源码；JavaScript、any/生成代码、已编译脚本以及签名兼容的方法仍会截获两个入口。提交7b984b8590eeba5b2ba7d2936cc3a4865e03cdae已有单一componentSetActiveSymbol、两个调用点和公开链路反向测试，12fc242却同时删除了它们。应让Component继续独占激活状态与生命周期顺序，让Entity只通过包内 Symbol 或模块级非实例入口触发，并删除普通字符串_setActive；这是替换旧协议，不是新增第二套协议，也不要保留 alias、wrapper 或 fallback。恢复addComponent → addChild → onAwake/onEnable链路测试，并断言用户字符串_setActive从未被调用。 -
[P1] 删除 phantom 排序状态，写回
ComponentsManager的唯一 dirty owner（packages/ui/src/component/UICanvas.ts:212-217，packages/core/src/ComponentsManager.ts:21-25,102-109，packages/core/src/Engine.ts:612-615）。UICanvas.sortOrder当前写入不存在的_overlayCanvasesSortingFlag，真实字段是_overlayCanvasesSortingDirty。首帧排序把真实 dirty 复位后，再修改已注册 overlay canvas 的sortOrder只会在 JS 对象上创建一个无人读取的平行字段；后续Engine虽继续调用sortOverlayUICanvases()，渲染与指针命中顺序仍停在旧值。这里的@ts-ignore正在遮住本 PR 已可见的 core owner 契约。请保留_overlayCanvasesSortingDirty这一份状态，删除 phantom 字段写入和 suppression，直接写真实 owner；增加两个重叠ScreenSpaceOverlaycanvas 在首次排序后交换sortOrder的公开链路测试，验证下一次更新后的顶层渲染/命中对象随之切换。 -
[P1] 让
ResourceManager声明真实的引用结果，不把第三份真相留给 consumer（packages/core/src/asset/ResourceManager.ts:581-602，packages/loader/src/resource-deserialize/resources/parser/HierarchyParser.ts:269-280，packages/loader/src/MaterialLoader.ts:46-49，packages/loader/src/SceneLoader.ts:19-22）。作者关于旧运行时已经可能解引用 null 的事实成立，但本问题针对的是本 PR 用stripInternal: false新发布的权威契约：实现对空 URL 和未登记 virtual path 明确返回null，签名却仍是AssetPromise<T>；合法的引用资源Shader实现IReferable而非EngineObject，又被T extends EngineObject排除。应由ResourceManager的泛型边界覆盖真实可引用对象，并用T | null表达结果；必需 prefab 的HierarchyParser在实例化前带上下文 reject，可选属性引用继续消费null（PrefabResource.test.ts:158-176已锁定该语义）。随后删除MaterialLoader、SceneLoader等 consumer 的相关 suppression；不要用 cast、全局 throw、compatibility fallback 或调用方各自的结果类型掩盖 owner 契约。 -
[P2] 机械清理仅因旧 internal 可见性存在的剩余 suppressions（例如
packages/galacean/src/ShaderPool.ts:82,90、packages/galacean/src/index.ts:29、packages/loader/src/AnimatorControllerLoader.ts:22、AudioLoader.ts:28、BufferLoader.ts:20、SpriteLoader.ts:18、packages/rhi-webgl/src/GLTransformFeedbackPrimitive.ts:83,87、packages/ui/src/component/UIBatchSorter.ts:143）。完整目标树仍有 299 条 TypeScript suppression，基线为 323 条；它们并非都与本 PR 有关，但上述已核实项仍只是在绕过“core@internal不进入声明”这一旧事实。@ts-ignore失效时不会自报错，上一项的 phantom 字段已经证明它会继续屏蔽协议漂移。请只删除同根因项并跑完整类型构建；删除后暴露的真实不匹配应在权威 owner 处修正，不能换成 cast、另一种 ignore 或兼容路径，确属 private/protected、平台类型或外部声明边界的 suppression 则保留。 -
[P2] 为非 MSAA 的 depth
TextureCube行为修复补反向测试（packages/rhi-webgl/src/GLRenderTarget.ts:246-252，packages/core/src/texture/RenderTarget.ts:201-210，tests/src/rhi-webgl/GLRenderTarget.test.ts:1-43）。公开RenderTarget构造链明确支持 depth texture，并专门为 “non-MSAA cube depth RBO” 计入内存；本次把TextureCube对象改为其.format后，才会在格式 switch 中创建正确的 renderbuffer，这是实际运行时修复。现有测试只导入Texture2D，覆盖TextureFormat.Depth16的非 MSAA/MSAA，删除本次转换仍会全绿。请增加 depthTextureCube用例，验证创建、激活指定 face、检查 WebGL error 并销毁；反向移除.format时测试应失败，同时在 PR 说明中明确这项运行时行为变化。
架构、熵增与测试治理
-
声明链的权威 owner 已从被裁剪的 core
.d.ts收回到完整 core 声明，方向正确；但净结果只删除 24 条 suppression，仍留下会隐藏真实漂移的旧路径。正确收敛是让声明直接驱动 loader、RHI、UI 和 XR 的类型检查，删除同根因 ignore，而不是让 consumer 维护 cast/注释协议。 -
激活链上游只有
Entity.addComponent与_setActiveComponents两个入口，下游三份阶段状态及回调顺序由Component独占。恢复单一 Symbol 并删除字符串方法后，owner、状态和转换数量都不增加；当前字符串分发反而把非虚控制权扩散到每个 consumer 实例命名空间。 -
overlay 排序的唯一事实应是
ComponentsManager._overlayCanvasesSortingDirty，数据流应为UICanvas.sortOrder → dirty=true → Engine render → sort/reset；删除无人读取的_overlayCanvasesSortingFlag后从两份状态回到一份，不需要同步层或新 flag。getResourceByRef同理应由实现与声明共同给出一份 nullability/类型事实，下游只按“必需或可选”消费。 -
GLTFResourcehelper 重命名、GLPrimitive平台类型收窄、createPlatformPrimitive(Primitive)与bindTexture收口没有新增缓存、镜像状态或第二条转换路径。最终 diff 唯一新增的 RHI 运行时分支语义是 cube-depth 格式转换，应由对应公开链路测试拥有。 -
最终净 diff 没有新增测试，且删除了中间提交中能反向证伪
_setActive碰撞的回归测试；现有 fixture/mock/snapshot 未改，也未发现为旧测试新增 compatibility branch。应按新权威契约补激活、overlay 动态排序和 cube-depth 测试，不得为历史测试保留 legacy 分发、fallback、wrapper 或镜像状态。

[P2] 让控制流表达合法输入，不保留不可达的 Texture fallback
更正我上一轮把这里视为 TextureCube 运行时修复的判断：RenderTarget 构造阶段会拒绝 _isDepthTexture === false 的 depth texture；当前实现中只有 Texture2D 会按深度格式设置该标志，而它已经被上面的 attachment 分支处理。TextureCube 和 Texture2DArray 都无法通过这条合法构造链，因此这个 ternary 的 Texture 分支不可达，并不是需要兼容的运行时路径。
建议只重排现有控制流：先按 Texture 分支处理合法的 texture attachment，再在非 Texture 且非 null 的分支把 _depth 直接传给 _getRenderBufferDepthFormatDetail，让 TypeScript 自然收窄到 TextureFormat。不要为这个不可能状态再增加 typeof guard、cast、fallback 或额外运行时校验；内部链路应直接依赖 RenderTarget 已建立的契约。这样既解决 stripInternal: false 暴露出的类型错误，也不会暗示引擎支持 cube depth。
There was a problem hiding this comment.
已按这个方向在 a170bbe15 完成修正。
前因是 stripInternal: false 让 RHI 跨包编译重新获得了 RenderTarget._depth: Texture | TextureFormat | null 的真实类型。此前该属性访问由 @ts-ignore 遮蔽，旧代码直接把 _depth 传给 _getRenderBufferDepthFormatDetail 时没有经过有效的联合类型检查。后来把条件写成 Texture && !TextureCube 后，TypeScript 会认为 else 中仍可能是 TextureCube | TextureFormat，上一版 ternary 只是局部归一化这个类型，没有表达上游控制流。
本次恢复为原有的两层结构：
- 外层先区分
Texture与非Texture； - Texture 内只为非 cube attachment 绑定 2D texture；
- 非 Texture 分支自然收窄为
TextureFormat，直接传给 renderbuffer format lookup； - 同时删除 ternary 和该处已经失效的
@ts-ignore，未增加 cast、guard、fallback 或额外运行时校验。
我保留了既有的 TextureCube 分支，没有借本次类型修复删除或新增 cube-depth 行为。当前 RenderTarget 校验确实使 cube depth 不可达，但仓库中英文文档仍声明 depth cube 支持，activeRenderTarget 也保留按 cube face 绑定的历史路径；这是本 PR 之前已经存在的契约不一致，不在 #3103 中顺带改写。
该改动不改变合法输入的运行行为，因此没有增加 TextureCube 运行时测试。验证结果：本地 pnpm b:all 通过；新 head 的 lint、三平台 build、四组 e2e、codecov workflow 与 codecov/patch 均已通过。

问题
-
[P1] 用 Component 的唯一非虚入口替换仍可被 consumer 截获的字符串分派（
packages/core/src/Component.ts:113，packages/core/src/Entity.ts:259,698，#3103）。目标树仍从两个 Entity 入口调用component._setActive(...)；stripInternal: false只会让重新编译且声明不兼容的 TypeScript consumer 报错，不能阻止 issue 中的 JavaScript、any、已编译脚本或签名兼容成员截获运行时调用。#3103 的 Expected behavior 明确要求该内部非虚操作不可被 consumerScriptmember 覆写，当前实现仍可复现其启动崩溃。7b984b8590eeba5b2ba7d2936cc3a4865e03cdae已实现一个包内componentSetActiveSymbol、替换两个入口，并从addComponent → addChild → onAwake/onEnable公开链路反向证伪；12fc242ccf079de815492c77b894209407fb36c7又将这三处和测试一起删除。保留 Component 对阶段状态及生命周期顺序的唯一 owner，但用该包内 Symbol 或模块级非实例入口替换字符串_setActive，删除旧字符串路径，不保留 alias、wrapper、fallback 或双路协议，并恢复该回归测试。 -
[P1] 删除 overlay 的 phantom dirty，写回 ComponentsManager 的唯一排序 owner（
packages/ui/src/component/UICanvas.ts:212-217，packages/core/src/ComponentsManager.ts:21-23,77-109，packages/core/src/Engine.ts:612-615，packages/ui/src/input/UIPointerEventEmitter.ts:42-52）。UICanvas.sortOrder在 suppression 下写入不存在的_overlayCanvasesSortingFlag，而 manager 仅消费并清除_overlayCanvasesSortingDirty。首次排序将真实 dirty 复位后，已注册 canvas 改变sortOrder只会向 JavaScript 对象写入无人读取的平行属性；Engine 不再重排，倒序 pointer hit testing 也继续使用旧数组顺序。保留 ComponentsManager 的_overlayCanvasesSortingDirty这一份事实，删除 phantom 写入及 suppression，令数据流收敛为UICanvas.sortOrder → dirty=true → Engine sort/render 与 pointer hit → dirty=false。补两个重叠ScreenSpaceOverlaycanvas 在首次排序后交换sortOrder的公开链路测试，断言下一帧的顶层渲染和命中对象同时切换。 -
[P1] 让 ResourceManager 声明它已实现的 nullable 引用结果，不把 nullability 分散给 consumer（
packages/core/src/asset/ResourceManager.ts:584-605，packages/loader/src/resource-deserialize/resources/parser/ReflectionParser.ts:117-123，packages/loader/src/resource-deserialize/resources/parser/HierarchyParser.ts:274-283，tests/src/loader/PrefabResource.test.ts:158-176）。getResourceByRef对空 URL 或未登记 virtual path 都明确AssetPromise.resolve(null)；现有 optional$reffixture 也锁定了这个正常消费语义，ReflectionParser 随后以resource &&使用它。但本 PR 刚将该 API 改为T extends LoadableResource并因stripInternal: false发布到声明，却在22a9cdd把AssetPromise<T | null>恢复为错误的AssetPromise<T>，使 HierarchyParser 获得虚假的 non-nullPrefabResource | GLTFResource后解引用。86a5a91b已有正确的 owner 修复、上下文错误和回归测试，22a9cdd又同时撤回。请保留LoadableResource，恢复 ResourceManager 的T | null结果；required prefab instance consumer 在该权威结果上 reject 并保留有上下文的错误，optional ReflectionParser 保持 null 语义。删除各 consumer 的假定、cast 或 suppression，而不是保留第二条 nullability 协议；保留现有 optional fixture，并恢复 missing prefab-instance mapping 的链路测试。
架构、熵增与测试治理
-
声明的权威 owner 已从被裁剪的 core
.d.ts收回 core 源与生成声明，且大部分 loader、RHI、UI、XR consumer 已直接使用该契约；LoadableResource也正确把 Shader 纳入唯一加载边界。但getResourceByRef的实现、声明和 optional consumer 仍分别给出 null、non-null、nullable 三份事实。让 ResourceManager 产出T | null后，required/optional consumer 只消费同一结果，不新增 fallback 或镜像状态。 -
激活链的上游只有
Entity.addComponent与_setActiveComponents，下游_awoken/_phasedActiveInScene/_phasedActive和 hook 顺序应由 Component 独占。当前字符串协议把这个非虚控制权扩散到每个 consumer 实例命名空间；一个包内身份替换并删除_setActive会从可覆写的隐式协议回到单一 owner，不增加状态、wrapper 或兼容分支。 -
overlay 排序的唯一持久状态应是 ComponentsManager dirty；当前真实 flag 与写而不读的 phantom property 构成两份状态。删除 phantom 后，render 与 input 都从同一排序数组消费结果，无需同步层。
-
最终三点 diff 没有测试文件改动；最新
22a9cdd还删除了86a5a91b刚添加的 missing-prefab mapping 回归。7b984b8的 activation 反向测试同样已在 PR 内被删除。没有发现为旧测试保留的 production compatibility branch、legacy fallback、wrapper 或镜像状态；应按上述权威契约恢复链路测试，而不是为旧行为保留字符串分派或错误 non-null 声明。

[P1] 用
Component的唯一非字符串入口恢复 non-virtual activation owner（packages/core/src/Component.ts:113，packages/core/src/Entity.ts:259,698，#3103）。目标树仍从两个Entity入口动态调用component._setActive(...)。stripInternal: false只能拦住重新类型检查且可见性不兼容的声明；同签名 public override 仍是合法 TypeScript，JavaScript、any与已编译 consumer 也仍可截获调用，进而跳过Component对_awoken/_phasedActiveInScene/_phasedActive和生命周期顺序的唯一写入。#3103 的 Expected behavior 明确要求该内部非虚操作不可被 consumerScriptmember 覆写，PR 仍声明Fixes #3103。7b984b8590eeba5b2ba7d2936cc3a4865e03cdae已证明一个包内componentSetActiveSymbol 可替换这两个入口并用公开链路反向证伪，12fc242ccf079de815492c77b894209407fb36c7又将其与测试删除。保留Component作为状态和顺序的唯一 owner，让Entity通过包内 Symbol 或模块级非实例入口触发，删除旧字符串_setActive，不保留 alias、wrapper、fallback 或双路协议；恢复addComponent → addChild → onAwake/onEnable回归测试，并断言用户_setActive从未被调用。 -
[P1] 删除 overlay 的 phantom dirty，写回
ComponentsManager的唯一排序 owner（packages/ui/src/component/UICanvas.ts:212-218，packages/core/src/ComponentsManager.ts:21-23,77-109，packages/core/src/Engine.ts:612-615，packages/ui/src/input/UIPointerEventEmitter.ts:42-50）。UICanvas.sortOrder在@ts-ignore下写入不存在的_overlayCanvasesSortingFlag，而 manager 只写入、消费并清除_overlayCanvasesSortingDirty。首次排序清除真实 dirty 后，已注册 canvas 再变更sortOrder只会在 JavaScript 对象创建无人读取的平行属性；Engine 继续渲染旧数组顺序，pointer emitter 也从同一旧数组倒序命中。保留ComponentsManager._overlayCanvasesSortingDirty这一份事实，删除 phantom 写入和 suppression，使数据流直接收敛为UICanvas.sortOrder → dirty=true → Engine sort/render 与 pointer hit → dirty=false。补两个重叠ScreenSpaceOverlaycanvas 在首次排序后交换sortOrder的公开链路测试，断言下一帧顶层渲染和命中对象同时切换。

引用链现在是
refs/virtual path → ResourceManager → T | null → required 或 optional consumer。ResourceManager是引用对象集合和 nullable 结果的唯一 owner；LoadableResource只扩展类型边界，未引入缓存、镜像状态、fallback 或第二条转换。可选ReflectionParser继续消费同一 null 事实，按已确认边界不在HierarchyParser新建 consumer-specific 运行时语义。 -
激活链的上游只有
Entity.addComponent与_setActiveComponents，下游阶段状态和虚钩子顺序由Component独占。当前字符串分派把这个 non-virtual 控制权扩散到每个 consumer 实例命名空间；单一包内身份替换并删除旧字符串路径会从两种归属回到一种，不影响有意 virtual 的 lifecycle hooks。 -
overlay 排序的真实状态已经集中在
ComponentsManager，但 phantom field 构成写而不读的第二份状态。删除它后 render 与 input 都消费同一已排序数组，不需要同步层。最终 net diff 没有测试文件；可选$reffixture 仍有效，而上述两个 P1 应补公开链路测试，不能为了旧测试保留字符串 dispatch、legacy fallback、wrapper 或镜像状态。

Summary
stripInternal: false@internalannotations while publishing occupied inherited member names to TypeScript consumersEngineObjectandIReferable, includingShadersortOrderchangesRoot cause
The core package stripped every
@internalmember from its declarations. TypeScript consumers therefore could not see inherited names such asComponent._setActiveand could declare a conflicting private method that compiled successfully but intercepted Engine runtime dispatch.Separately,
UICanvas.sortOrderwrote a misspelled_overlayCanvasesSortingFlagproperty whileComponentsManageronly consumes_overlayCanvasesSortingDirty. After the first sort, later order changes therefore left both rendering and pointer hit testing on the stale shared canvas order.Design
Core declarations now preserve internal members. This gives
Component,Renderer, and other extensible core classes one consistent TypeScript collision contract instead of exposing names only after individual incidents.The supported TypeScript consumer boundary is the acceptance target: an unrelated
_setActivedeclaration now fails compilation withTS2416. JavaScript,any, precompiled consumers, and deliberately signature-compatible overrides are not runtime-isolated by this PR.The declaration switch also made cross-package internal contracts type-checkable.
ResourceManagernow models loadable resources asEngineObject | IReferable, soShaderreferences no longer need a consumer suppression. Its publishedgetResourceByRefresult isAssetPromise<T | null>, matching the existing empty-URL and missing-virtual-path results without adding consumer guards or changing runtime behavior.UICanvas.sortOrdernow invalidates the existingComponentsManager._overlayCanvasesSortingDirtyowner directly. No second flag, wrapper, fallback, or per-frame sort was added.No runtime activation dispatch, lifecycle behavior, compatibility branch, reserved-name list, consumer-side compiler rule, cache, or fallback was added. Suppressions were removed only when a two-configuration declaration build proved they were required with
stripInternal: trueand obsolete withstripInternal: false; suppressions covering real mismatches remain.Validation
