feat(physics): add raycastAll

[luzhuang]

Fixes #1554
Fixes #1271

Changes

• Add PhysicsScene.raycastAll with a boolean hit flag and an optional caller-owned output array, following the existing raycast argument forms. Output length equals the actual hit count, with unspecified order, positive-distance hits, and layer filtering.
• Reuse the output array's HitResult, point, and normal objects through a weak cache shared across scenes. Reserve distinct caller-provided objects before filling spare slots, including after reordering, replacement, duplicate entries, or sparse-array edits. Inactive cached objects have entity/shape references cleared; replaced objects are dropped from the cache. The next query using the same output array overwrites its result objects, so callers must copy values they need to retain.
• Clearing the output array preserves reusable storage. Discarding the array makes its weak cache collectible; engine.resourceManager.gc() or scene destruction releases hidden caches without changing caller-held results. Because storage follows caller arrays across scenes, these lifecycle boundaries invalidate the shared cache, including unused capacity from other scenes.
• Normalize overload arguments directly on the implementation parameters, preserving all public call forms and defaults without extra parsing locals.
• Calls without an output array perform only the existing hit test. All-hit queries retain every native touch chunk, including more than 256 hits, without a fixed output-capacity limit.
• Filter candidates natively and give each scene reusable native buffers. Return packed values across WASM/JS while preserving full 32-bit shape IDs. Snapshot all-hit values before output callbacks so nested queries cannot overwrite outer results.
• Remove shared query callback state and all 10 query/contact try/finally blocks. Native ownership replaces manual per-element Embind cleanup.
• Keep public query participation separate from native scene-query flags. isSceneQuery=false excludes a shape from public queries while preserving character-controller collisions. Replay the setting for clones and deferred/recreated controllers without a separate query-enabled adapter field.
• Deliver contact IDs and values in bulk, then copy them into pooled engine events before the native callback buffer is reused.
• Tighten public query contracts, remove redundant private-field prose, and include matching standard/SIMD runtime pairs for Engine and e2e.

const hits: HitResult[] = [];
if (scene.physics.raycastAll(ray, 100, layerMask, hits)) {
  // Consume all hits before reusing this output array.
}

Reusing output storage removes repeated per-hit HitResult/vector allocations after capacity is sufficient. The full query path still allocates a callback and a typed-array snapshot; this is not a zero-allocation API.

Runtime dependency and merge gate

The paired native implementation is galacean/physX.js#24 at c6bc6afde59eb1aedb617fd0c1a38fd58dce3a6c, based on current main after #22 and #23 merged. Current Engine commit: 35b799fc9298cb2cd23eb5a84c26d740c3f4096c.

The internal binding ABI changes. PxSceneQueries replaces the old query/filter/hit-wrapper APIs; contact callbacks receive shape IDs and a borrowed value buffer. The bundled local runtime pairs match this implementation, while the current default CDN URLs still point to the previously published #22 runtime.

Before merging/releasing this Engine consumer: merge the paired native implementation, publish a new immutable standard/SIMD JS+WASM set, update the default URLs, and verify the default construction/query/contact path against those published assets. This update does not publish CDN assets.

Validation

• pnpm run build: module build and all package declaration/type checks passed. All six common call forms and three explicit optional-argument omissions typecheck with a boolean return.
• Chromium affected suites: 278/278 across 14 files with explicit standard WASM, and 278/278 with explicit SIMD.
• Regression coverage includes prefilled/sparse output arrays, hit/point/normal identity reuse, shrinking/empty results, caller-cleared/reordered/replaced/sparse/duplicate-filled arrays, cache release during resource GC and scene destruction, shared output across scenes, 257+ hits, full 32-bit IDs, layer changes, nested callbacks, clones, controllers, and contact events.
• Query-disabled walls remain ignored by public queries and still block controller movement, matching the original-PR runtime comparison.
• Changed-source ESLint/fixes and pre-commit hooks passed with no errors; Prettier, diff checks, and public parameter-tag checks passed.
• The unchanged paired native head passed standard/SIMD builds. All four runtime hashes match both packages/physics-physx/libs and e2e/.dev byte-for-byte.
• A standard/SIMD material assertion difference also reproduces on the original PR source and original assets; its float tolerance covers both modes.

A paired Chromium/SIMD comparison used the exact compiled implementations before and after the caller-array ownership fix in the same 257-box scene, with 10,000 warmup calls per variant and 15 paired rounds of 1,000 queries per variant. Full-output medians were 40.6 µs before and 41.1 µs after (about 1.2% overhead). Normal reuse stays linear and allocates no temporary synchronization collections; changed entries use identity searches, so large rearrangements can take quadratic time. This is a correctness/lifetime fix, with no speedup or GC-pause improvement claimed. Published default-runtime validation remains pending.

Walkthrough

The physics scene APIs now support multi-hit raycasts. The core collects HitResult objects, and the PhysX backend uses raycastMultiple with filtering and a 256-hit limit. Native hit and collection resources are released during raycast, overlap, and contact processing. Default WebAssembly runtime URLs also change.

Full details: Linked Issues check

Explanation

The reviewed head satisfies the coding requirements in both active linked issues. For #1554, PhysicsScene.raycastAll and IPhysicsScene.raycastAll are implemented with HitResult collection, distance and layer filtering, and all-hit callback processing. The reviewed physics interfaces and PhysXPhysicsScene also contain the requested sweep and overlap capabilities. For #1271, ColliderShape.isSceneQuery documentation now states that the flag applies to raycasts, shape casts, and overlap queries. The broader scope means an API rename is not required.

Full details: Out of Scope Changes check

Explanation

The changes stay within the linked issue scope. The callback collector, Embind cleanup, tests, documentation, and regenerated or updated PhysX runtime assets support raycast-all, overlap, sweep, or scene-query behavior. No unrelated product behavior is established by the reviewed evidence.

Full details: Docstring Coverage

Blocker fixes pushed in a0cd7b8.

• The upstream all-hit path now streams processTouches chunks through one custom PxRaycastCallbackCollector; the previous Ext -1 retry could not observe eNO_BLOCK touch-buffer clipping.
• raycastAll now deletes each Embind get(i) PxRaycastHit copy in a local finally, including when the hit callback throws.
• _overlapMultiple now uses the same element finally cleanup and keeps vector deletion in an outer finally.
• The focused PhysicsScene test now creates 257 hit shapes and verifies count plus every shape/entity identity.

[luzhuang]

中央独立复核通过当前 head a0cd7b8，无 blocker。raycastAll 通过 upstream collector 一次 query 收齐全部 touch；主线程复跑 PhysicsScene 53/53，257-hit case 校验全部 shape/entity identity。Embind Vector get(i) 的拥有型 copy 在 raycastAll 与 overlapMultiple 中均由局部 finally 删除，vector 由外层 finally 删除；回调异常也不会泄漏。四份 standard/SIMD Engine/e2e 产物与 physX.js wasm_build SHA256 完全一致。#1271 仅修正文档是正确结论：isSceneQuery 实际控制 raycast、shape cast 与 overlap，不应重命名。未合并、未启用自动合并。

结论

P0 阻塞。本轮完整复核了 dev/2.0@490d2bc8 到目标 HEAD a0cd7b808297dba1ba5438b0e90f19f646cb7bd8 的全量 diff，并增量核对了 cfc261ac...a0cd7b80 的 blocker 修复；代码内的新 binding 与资源释放已闭环，但默认用户加载的 PhysX runtime 仍是旧协议，raycastAll() 会必现调用不存在的方法。本次实际 review 动作为 REQUEST_CHANGES，目标 HEAD 为 a0cd7b808297dba1ba5438b0e90f19f646cb7bd8。自动 CR 不替代人工 Reviewer 的合入门禁；修复后仍需人工 Reviewer 审核并决定是否 APPROVE。

已关闭问题清单

• eNO_BLOCK 下固定 touch buffer 会截断全量命中 — 已由上游 galacean/physX.js#22@bb070c3 修复：权威 PxScene::raycast 路径改为 PxRaycastCallbackCollector::processTouches 连续收集每个 chunk，删除无效的 Ext overflow retry；本 PR 的 257-hit 公开链路测试逐一核对 shape/entity identity，能够反向守住该问题。
• Embind vector.get(i) 返回拥有型 copy，逐命中泄漏 — 已由 a0cd7b80 修复：raycastAll 与 _overlapMultiple 均在元素级 finally 删除 copy，并由外层 finally 删除 vector；回调抛错路径也完成释放。

问题

1. [P0] 默认 PhysX runtime 仍是旧协议，默认配置下 raycastAll() 必现崩溃 — packages/physics-physx/src/PhysXPhysics.ts:66-73 仍指向原 standard/SIMD CDN URL，而新调用已经在 packages/physics-physx/src/PhysXPhysicsScene.ts:293 直接执行 _pxScene.raycastMultiple(...)。我实际加载两份默认 CDN 模块后，standard 与 SIMD 的 typeof PxScene.prototype.raycastMultiple、typeof VectorPxRaycastHit 都是 undefined；同样检查本 PR 提交的两套本地产物则都是 function。因此用户按默认方式 new PhysXPhysics() 初始化后调用公开 PhysicsScene.raycastAll()，会得到 _pxScene.raycastMultiple is not a function，新功能不可用。现有测试在 tests/src/core/physics/PhysicsScene.test.ts:23-24,130-133 显式覆盖 URL 指向仓库内产物，所以 CI 绿无法发现这个真实发布路径断裂。请先合入上游 source owner galacean/physX.js#22@bb070c3，将本 PR 的 standard/SIMD 四个配对文件（JS + WASM）发布到新的不可变 URL，更新这里的两个默认入口，并从 CDN 回读核对 SHA256 与 packages/physics-physx/libs / e2e/.dev 的提交产物完全一致；同时补一条默认 runtime contract/发布守卫。不要在生产代码里为旧 CDN 增加 raycastSingle fallback 或 compatibility branch。

2. [P2] raycastAll 把唯一输出回调声明成可选，增加了无可观察结果的空语义 — packages/design/src/physics/IPhysicsScene.ts:76-81 的方法返回 void，却允许省略 onHit；PhysXPhysicsScene.ts:306 因而保留 if (hit && hits) 分支。省略时仍执行完整 native 查询和分配，随后丢弃全部结果；而唯一生产调用方 PhysicsScene.raycastAll 始终提供回调。请让 IPhysicsScene 的 onHit 成为必选契约，删除后端的 hit 可选态与对应分支，并在该公开接口 TSDoc 中补齐四个 @param。应保留的 owner 是 IPhysicsScene.raycastAll 的“逐命中回调”契约，不需要第二种无结果模式。

架构、熵增与测试治理

上游数据流是 Ray + layerMask + ColliderShape.isSceneQuery 进入 Core PhysicsScene；Core 是过滤规则与 HitResult 映射的 owner。下游由 PhysXPhysicsScene 拥有同步查询和 Embind 生命周期，再由 physX.js binding 拥有 PhysX touch 分块协议。本 PR 用 _setHitResult 合并了单命中/全命中的重复映射，新的 _pxRaycastAllFilterData 是热路径复用的单一 filter policy，且上游 collector 已替换并删除旧 Ext retry；这些部分没有新增平行状态机或 legacy 路径。

当前真正的熵增发生在发布协议：上游 source 与仓库内 standard/SIMD 产物已经升级到 raycastMultiple，默认 CDN 仍停留在旧契约，形成两版 runtime 真相。应保留 physX.js 合入 commit 作为源码 owner、由 PhysXPhysics 默认 URL 指向的不可变 CDN build 作为发布 owner，并机械校验 packages/physics-physx/libs 与 e2e/.dev 两份投影；删除旧 URL 引用，不增加同步层或 fallback。257-hit 测试是有效的公开链路回归，但它只消费本地产物；必须补默认 runtime/发布边界守卫，才能覆盖本次 P0。现有 fixture/mock/snapshot 未锁定已退场契约，也没有理由为旧测试保留 compatibility branch。

[luzhuang]

P2 addressed in e8e711a.\n\n- IPhysicsScene.raycastAll now requires onHit and documents all four parameters.\n- PhysXPhysicsScene uses the same required name and no longer keeps the no-output callback branch.\n- Full-repo rg found one production caller, PhysicsScene.raycastAll, which always supplies the callback; PhysXPhysicsScene is the only backend implementation. No mock, example, docs, or supported Galacean default-branch consumer relies on omitting it.\n- The existing physics contract test now proves a hit-producing call without the callback does not silently succeed, then verifies the required callback receives both shape IDs.\n\nLocal validation:\n- HEADLESS=true node_modules/.bin/vitest run tests/src/core/physics/PhysicsScene.test.ts: 53/53 passed in Chromium against rebuilt 2.0.0-alpha.43 modules.\n- pnpm build: passed, including module build and all package declaration tsc tasks.\n- pnpm lint: exit 0, 0 errors; existing repository warnings remain.\n- Prettier check and git diff --check: passed.\n- Generated IPhysicsScene and PhysXPhysicsScene declarations both show a required fourth parameter.\n\nRemote readback: PR head and refs/heads/codex/issue-1554 both resolve to e8e711a. New-head CI is green: lint, Linux/macOS/Windows builds, all four E2E shards, codecov job, codecov project/patch, and labeler passed.\n\nP0 intentionally remains open and unchanged. The default standard and SIMD CDN runtimes still expose neither PxScene.prototype.raycastMultiple nor VectorPxRaycastHit, while both committed local runtime pairs expose them. galacean/physX.js#22 remains OPEN / REVIEW_REQUIRED at bb070c3f7219c18bd02e0b034e8710829e5e72d6. This PR must remain blocked until #22 is merged, four immutable JS/WASM artifacts are published, default URLs and hashes are updated, and a default-runtime release guard is added. No old-runtime fallback or capability-probe workaround was added; no merge, auto-merge, or CDN publication was performed.

[luzhuang]

中央复核当前 HEAD e8e711a927851cbf99e18b4322475bdd43983335：上一轮 P2 已收掉，IPhysicsScene.raycastAll 的唯一输出回调现为必选，PhysX 后端删除无结果分支并补齐公开 TSDoc；主线程独立复跑 PhysicsScene 53/53 通过。P0 仍是发布边界 blocker：上游 physX.js#22 当前仍 OPEN / REVIEW_REQUIRED，四份 standard/SIMD JS/WASM 尚未发布到新的不可变 CDN URL，因此本 PR 不能通过 fallback 绕开，也还不能视为可合入。未合并、未启用自动合并。

Update the default PhysX runtime URLs before enabling raycastAll.

initialize() loads the default standard or SIMD CDN pair. Neither paired WASM module exposes raycastMultiple or VectorPxRaycastHit. raycastAll calls _pxScene.raycastMultiple(...) without a capability check, so it can fail before returning hits.

已关闭问题清单

• raycastAll 在 eNO_BLOCK 下被固定 touch buffer 截断 — 已由上游 galacean/physX.js#22@bb070c3 修复：PxRaycastCallbackCollector::processTouches 连续收集各 chunk，Engine 的 257-hit 公开链路测试逐一覆盖 shape/entity identity。
• Embind vector.get(i) 返回拥有型 copy，逐命中泄漏 — 已由 a0cd7b80 修复：raycastAll 与 _overlapMultiple 都在元素级 finally 删除 copy，并由外层 finally 删除 vector；回调/映射抛错路径也能释放。
• raycastAll 的唯一输出回调被声明为可选 — 已由 e8e711a9 修复：IPhysicsScene.raycastAll 的 onHit 成为必选并补齐四个 TSDoc @param，PhysX 后端删除无输出回调分支；唯一生产调用方始终提供回调，新增测试也验证必选契约和两项 shape ID。

问题

1. [P0] 默认 PhysX runtime 仍是旧协议，默认配置下 raycastAll() 必现崩溃 — packages/physics-physx/src/PhysXPhysics.ts:66-73 仍指向旧 standard/SIMD CDN pair，而 packages/physics-physx/src/PhysXPhysicsScene.ts:293 已无条件调用 _pxScene.raycastMultiple(...)。我在提交前重新加载了这两个默认模块：两者的 PxScene.prototype.raycastMultiple 与 VectorPxRaycastHit 均为 undefined；目标 HEAD 提交的 standard/SIMD 模块则均为 function。默认 CDN 四文件的 SHA256 仍与 dev/2.0 产物相同，也与本 PR 新产物不同，所以 new PhysXPhysics() 用户会得到 _pxScene.raycastMultiple is not a function。tests/src/core/physics/PhysicsScene.test.ts:24-26,127-135 显式覆盖 URL 到仓库内产物，当前全绿 CI 无法覆盖该发布断层。请先合入 galacean/physX.js#22@bb070c3，将 standard/SIMD 的 JS + WASM 配对产物发布到新的不可变 URL，更新两个默认入口，从 CDN 回读校验四份 SHA256 与 packages/physics-physx/libs / e2e/.dev 完全一致，并补构建/发布侧默认 runtime contract guard。应保留 physX.js commit 作为源码 owner、PhysXPhysics 默认 URL 作为发布 owner；删除旧 URL 引用，不要增加旧 runtime fallback、capability compatibility branch 或第二条查询路径。

2. [P0] 同一 all-hit 根因仍留在 overlap*All，超过 256 个重叠 shape 会静默缺失 — packages/physics-physx/src/PhysXPhysicsScene.ts:576-600 的 _overlapMultiple 仍把 256 作为 overlapMultiple 的结果 buffer 上限；上游 SceneBinding.h:245-255 仍调用 PxSceneQueryExt::overlapMultiple 并直接返回这段固定 vector。PhysX 真源在 ExtSceneQueryExt.cpp:155-173 强制 eNO_BLOCK，而 PxHitBuffer 的固定 touch buffer overflow 会任意丢弃后续 touch 且不报错。用目标 HEAD 提交的 standard runtime 放入 257 个同时重叠的 box 后，我实际得到 returned=256, unique=256；Core 的 overlapBoxAll / overlapSphereAll / overlapCapsuleAll 只会映射这些 ID，调用方既看不到容量也看不到 overflow。此项不是重提已关闭的 raycast collector：raycast 路径已改为分块 collector，残留的是本 PR 在 a0cd7b80 直接修改资源 ownership 的 sibling overlap 路径。请让 physX.js 的直接 callback collector 成为 all-hit 唯一 owner，将 collector 机械复用于 PxOverlapHit，删除 PxSceneQueryExt::overlapMultiple 的固定结果路径，让 256 只表示 chunk size；随后重建四份 runtime，并补一条从公开 overlap*All 入口验证 257 个 shape identity 的反向测试。不要用提高常量、截断标记或 Engine 侧重试形成第二套协议。

架构、熵增与测试治理

上游 PhysicsScene 是 Layer + ColliderShape.isSceneQuery 过滤与 HitResult 映射的 owner；IPhysicsScene 只拥有后端回调契约；PhysXPhysicsScene 拥有同步查询、可复用 filter data 与 Embind 生命周期；physX.js 拥有 PhysX touch 分块协议；PhysXPhysics 默认 URL 则是用户实际加载版本的发布 owner。e8e711a9 删除了可选回调模式，_setHitResult 合并了单命中/全命中的重复转换，独立 _pxRaycastAllFilterData 只承载 NO_BLOCK 的差异策略，这些改动没有新增镜像状态或 compatibility 分支。

当前净熵增有两处：源码/仓库产物已经是新 binding、默认 CDN 仍是旧 binding，形成两版 runtime 真相；同一“返回全部 touch”事实又由 raycast collector 与 overlap 固定 Ext buffer 两条协议分别拥有。前者应以新不可变 CDN pair 收口，后者应以 physX.js callback collector 收口并删除固定结果路径。Engine/e2e 的四份产物当前分别共享相同 blob，适合作为机械投影而不是独立 owner。257-hit raycast 测试是有效公开链路测试，回调契约测试没有迫使生产代码保留旧可选分支；但还缺 257-overlap 链路测试与默认 runtime 发布守卫。现有 fixture/mock/snapshot 没有锁定已退场契约，也没有理由为旧测试保留 fallback、wrapper 或第二条转换/校验路径。

Updated at e312778389e162f949aa2bd8facc132e6521385a, pushed non-force.

This update consumes physX.js PR #22 at 7adf6fe686da90a07bca6c93f44b01969d601a91. The public overlapBoxAll/overlapSphereAll/overlapCapsuleAll path now preserves all 257 identities; the focused PhysicsScene suite is 54/54, including Embind element/vector cleanup and callback-throw recovery. Standard/SIMD JS+WASM files in packages/physics-physx/libs and e2e/.dev match physX.js/wasm_build byte-for-byte.

No binding signature or default CDN URL changed. The sole remaining external blocker is upstream merge followed by immutable publication of the four runtime assets, after which the default CDN URLs can be updated and read back. No merge, auto-merge, or CDN publication was performed.

Current-head re-review at e312778: the overlapAll truncation P0 is closed. Engine consumes physX.js 7adf6fe6 artifacts byte-for-byte in packages and e2e, public box, sphere, and capsule overlapAll preserve all 257 shape identities, callback-throw cleanup is covered, PhysicsScene passes 54/54, physics-physx tsc and all substantive CI builds and E2E shards pass. One P0 remains outside this commit: the default CDN still serves the old protocol and must only be changed after physX.js PR 22 is merged and four immutable runtime assets are published and read back. No fallback or unhosted URL was added. Requesting human re-review; not approving my own PR.

结论

P0 阻塞。本轮以 dev/2.0@490d2bc8 为 merge base 完整复核了目标 HEAD e312778389e162f949aa2bd8facc132e6521385a 的全量 diff，并增量核对了 e8e711a9...e3127783：上一轮 overlap 截断 P0 已关闭，除仍开放的默认 PhysX runtime 发布断层外，未发现新的 P0/P1/P2。本次实际 review 动作为 REQUEST_CHANGES，目标 HEAD 为 e312778389e162f949aa2bd8facc132e6521385a。自动 CR 不替代人工 Reviewer 的合入门禁；修复后仍需人工 Reviewer 审核并决定是否 APPROVE。

已关闭问题清单

• raycastAll 在 eNO_BLOCK 下被固定 touch buffer 截断 — 已由上游 galacean/physX.js#22@bb070c3 修复：PxRaycastCallbackCollector::processTouches 连续收集各 chunk，Engine 的 257-hit 公开链路测试逐一覆盖 shape/entity identity。
• Embind vector.get(i) 返回拥有型 copy，逐命中泄漏 — 已由 a0cd7b80 修复：raycastAll 与 _overlapMultiple 都在元素级 finally 删除 copy，并由外层 finally 删除 vector；回调/映射抛错路径也能释放。
• raycastAll 的唯一输出回调被声明为可选 — 已由 e8e711a9 修复：IPhysicsScene.raycastAll 的 onHit 成为必选并补齐四个 TSDoc @param，PhysX 后端删除无输出分支；唯一生产调用方始终提供回调。
• overlap*All 超过 256 个 shape 时静默截断 — 已由本轮 e3127783 消费上游 galacean/physX.js#22@7adf6fe6 修复：PxQueryCallbackCollector<HitType> 现在是 raycast/overlap 分块协议的唯一 owner，旧 PxSceneQueryExt::overlapMultiple 固定结果路径已删除；目标 package/e2e 的 standard/SIMD 资产分别共享相同 Git blob，CI 的公开 box/sphere/capsule 链路均保留 257 个 shape identity，PhysicsScene 54/54 通过。

问题

1. [P0] 默认 PhysX runtime 仍停留在旧协议，默认配置调用 raycastAll() 必现崩溃 — packages/physics-physx/src/PhysXPhysics.ts:68-73 仍指向旧 standard/SIMD CDN pair，而 packages/physics-physx/src/PhysXPhysicsScene.ts:293 已无条件调用 _pxScene.raycastMultiple(...)。本轮重新实例化四个模块后，目标 HEAD 的 standard/SIMD 均暴露 PxScene.prototype.raycastMultiple 与 VectorPxRaycastHit，两个默认 CDN 模块则两项均为 undefined；默认 CDN 的 JS/WASM 四文件仍与 dev/2.0@490d2bc8 逐字节相同、与目标产物不同。因此用户以 new PhysXPhysics() 使用默认 URL 时会得到 _pxScene.raycastMultiple is not a function。tests/src/core/physics/PhysicsScene.test.ts:24-26,127-135 显式覆盖 URL 到仓库内产物，所以当前 54/54 与 100% patch coverage 都无法覆盖这个发布边界。请先合入 source owner galacean/physX.js#22@7adf6fe6，发布新的不可变 standard/SIMD JS + WASM 配对资产，更新 PhysXPhysics 的两个默认入口，并从 CDN 回读校验四份 SHA256 与 packages/physics-physx/libs / e2e/.dev 完全一致；同时在构建/发布侧增加默认 runtime contract guard。应保留 physX.js 作为 binding 源码 owner、不可变 CDN pair 作为发布产物、PhysXPhysics 默认 URL 作为发布指针；删除旧 URL 引用，不要增加旧 runtime fallback、capability compatibility branch、wrapper 或第二条查询路径。

架构、熵增与测试治理

数据流已核对为：调用方把 Ray + distance + layerMask + result array 交给 Core PhysicsScene；Core 是 Layer / isSceneQuery 过滤及 HitResult 映射的 owner；IPhysicsScene 只拥有逐命中后端契约；PhysXPhysicsScene 拥有同步查询、filter data 与 Embind 生命周期；physX.js 拥有 PhysX touch 分块收集协议；PhysXPhysics 的默认 URL 则决定用户实际加载的发布版本。下游只消费 Core 映射后的 shape/entity/point/normal，不再重复转换。

相对上一轮，all-hit 协议已从“raycast collector + overlap 固定 Ext buffer”两条路径收口为一个泛型 collector，删除了重复协议；必选回调、共享 _setHitResult 和逐元素释放也没有引入镜像状态、平行状态机或 compatibility 分支。Engine package 与 e2e 资产是同一构建的机械投影，不是独立 owner。当前唯一净熵增仍是仓库源码/本地产物已经升级、默认 CDN 仍是旧 binding，形成两版 runtime 真相；应通过发布新 pair 并删除旧 URL 引用收口，而不是在 Engine 再加同步层或 fallback。

测试治理方向正确：257-raycast 与三种 257-overlap 都从公开入口验证完整 identity，异常测试覆盖元素/vector 清理，CI 在 build 后运行当前产物并得到 PhysicsScene 54/54、全量 1689/1689，修改行 patch coverage 为 100%。现有 fixture/mock/snapshot 没有锁定已退场契约，生产代码也未为旧测试保留 legacy 路径；唯一缺口是这些测试主动覆盖成本地产物，尚不能守住默认 CDN 发布契约。

Default runtime URLs now point at the immutable CDN assets published from this branch's standard/SIMD runtime (physX.js #22): release.js AEbPcQJREEVY, release.simd.js Ay0OhRbvotbk; the JS files embed wasm URLs ABqCMTojSOLw / AEP8oRqdrhYk. All four verified by SHA256 read-back (wasm 57622384 / 120ba1a3; JS byte-identical to libs). Commit 8d34f8a.

[GuoLei1990]

@luzhuang 已完成查询与接触数据边界的优化，并按现有 raycast 的调用习惯统一了新增接口。当前 Engine 提交 2252eee34b916998b3ab5db4dff82abdd964c399，配套 physX.js #24（c6bc6afde59eb1aedb617fd0c1a38fd58dce3a6c）。

const hits: HitResult[] = [];
if (scene.physics.raycastAll(ray, 100, layerMask, hits)) {
  // 本次全部命中信息在 hits 中
}

• 返回 bool 表示是否命中；输出数组长度为实际命中数。复用数组时也复用 HitResult、point 和 normal，命中减少、清空后恢复、跨 Scene 查询都复用已有对象。下次使用同一数组会覆盖旧对象，需要长期保留的值须复制。省略输出数组时只执行命中判断。
• 参数解析直接在实现参数上归一化，保留原有六种常用调用形式，以及显式传 undefined 时的默认值；对象缓存和 count 保持不变。
• 查询过滤在原生完成，每个 scene 复用原生结果缓冲并批量返回数值；删除 _currentOnQuery、逐命中 Embind 对象清理和 10 处 try/finally。保留超过 256 命中的完整结果、完整 32 位 shape ID 和嵌套查询的数据稳定性。
• isSceneQuery 在独立原生过滤元数据中记录，覆盖克隆与控制器延迟创建/重建。保留控制器碰撞所需的原生查询标记，查询排除不会变成角色穿墙。
• 清理私有字段冗余注释，补齐公开参数、无序结果、对象复用和覆盖约定。底层仍有每次查询的回调与数值快照分配，因此只承诺减少 GC，不称整条路径零分配。

验证：Engine 模块与全包声明构建通过；六种常用调用形式及三种显式省略可选参数的类型检查通过；标准 WASM 和 SIMD 各 273/273 通过，包括共享输出数组跨 Scene 的引用清理回归；ESLint、Prettier、提交钩子通过。配套原生标准/SIMD 构建及产物匹配检查已通过，本次接口调整无需再改原生绑定。

本次参数解析简化的性能对照在同一个 Chromium/SIMD、257 个静态盒体场景中，分别预热 10,000 次，再做 15 轮交替对照，每轮每个实现各运行 1,000 次查询。完整输出查询的中位数为 35.6 µs → 35.6 µs，六种场景的中位数变化均不到 1%。这次收益是实现更直接，未宣称参数简化带来速度提升；仅衡量查询耗时。

合并/发布前仍需配套运行时： 当前默认 CDN 仍是旧 ABI。需要合入原生 #24、发布新的标准/SIMD 四个不可变 JS/WASM 资源、更新默认 URL，并验证默认构造与查询/接触链路。仓库内 libs 和 e2e/.dev 已同步新产物，当前未发布 CDN 资源。
