阶段 3：实时数据 —— 采样、合成、最新帧调度与适配器 - What: sampling.py 实现 SurfaceSampler（向量化四点双线性：无效 tap 不计入也不致无效、任一**正权** tap 无效即整顶点无效且值为 NaN、域/形状不符先拒；采样表只在加载时构建）与 remap_to_domain（按 unroll 映射 gather，空洞保持 NaN 且 valid=False，保留尾随轴以支持矢量场）。composer.py 实现 SceneComposer.compose（域校验 → 采样 → 位移 → **从形变后位置重算法线**；scalar 绝不成以 display_gain；approximate 位移产生 display_illustrative(info) 诊断、calibrated 不产生、无位移则着色并报 field_unavailable）与 build_rest_frame（参考帧：scalar 全 NaN、valid 全假、descriptor=unavailable/display_only），gl_backend.rest_surface 改为委托它，避免两处定义。coordinator.py 实现完整调度：容量 1 双 mailbox、generation/来源/会话三重过期拒绝并计数、**最多一次合成在飞行**、可见性挂起/恢复、设置变更（倍率变化重合成**屏幕上那一帧**）、close 幂等；submit 只做身份与形状的廉价校验，绝不等显示。adapters.py 实现 Finger/Box 适配器：|flow| 或 depth 响应、可选经 unroll 映射 remap、设备 valid_mask 优先、域不符时**发布空**并报出所见的两个形状；一律不造位移（未标定的毫米不如没有），并新增 display_illustrative 到诊断码表（info）。assets.py 从"桩类堆"改成门面：re-export 真正实现 + SceneCompiler.compile（外壳 GLB 与预算检查；加密请求明确拒绝并指向阶段 5）。测试：shared/tests/test_scene3d_live.py 25 项（采样/无效语义/倍率只影响位置/示意形变标注/法线重算/remap 空洞/参考帧/只读数组）、apps/studio/tests/test_scene3d_coordinator.py 13 项（状态机、过期、替换计数、单飞行、submit p99<1ms、切换场景丢弃在飞结果、隐藏挂起、倍率重合成、close 幂等）、test_scene3d_adapters.py 13 项；并把三处"桩仍未实现"的过时断言改成对已实现行为的断言。docs/architecture/studio-3d-stages.md 阶段 3 记为完成。 - Why: 阶段 3 决定"屏幕上的颜色和力值到底对应什么"。三条最容易错且肉眼看不出来的规则必须由代码而不是约定来保证：无效点不是 0（NaN 与 valid 分离，否则缺口会被画成一个测量值）、显示倍率只动位置不动测量（否则色标悄悄变了含义）、以及显示永远不能给采集施加背压（容量 1 mailbox + 单飞行合成 + 廉价 submit）。 - Verification: shared 全量通过（scene3d 相关 103 项：contracts 26、assets 33、package 19、live 25）；studio 全量通过（scene3d 相关 54 项：stage1 24、skeleton 4、coordinator 13、adapters 13；GL 冒烟 10 项在真实 context 下另行通过）；ui_check 554 项 0 失败。过程中修掉 3 个真实缺陷：倍率变化时用 incoming.peek() 取不到"屏幕上那一帧"（已被消费）导致改了倍率画面不动——改为保留 _last_field_frame；display_illustrative 不在码表里被默认成 error；assets.py 里与 package/legacy 同名的重复桩类（会误导集成者，已改为门面）。另修正两处我自己的错误断言（对称凸起顶点法线本就竖直；pytest.approx 不能直接 .all()）。 - Not in this change: 手势与面板（阶段 4）；示意位移的真实来源（需要 SDK lift + 已确认尺度，现阶段 adapter 一��� displacement=None）；app_window 接线与记录隔离（阶段 4）。

runtime, because the SDK's arrays are that thread's working memory;
|
||||
* it copies what the frame needs and publishes it read-only — the GUI thread must
|
||||
never reach back into a live runtime;
|
||||
* it copies **nothing** when the three-dimensional view is not subscribed to, and
|
||||
returns ``None`` when the frame carries no usable field. A frame is never
|
||||
assembled from two different acquisitions, and a missing field is never filled
|
||||
in from the previous one.
|
||||
* it publishes **nothing** when the frame carries no usable field, or when the
|
||||
field is on a different grid than the scene's UV domain. A remap that is not
|
||||
configured is not guessed at: the adapter says which shapes it saw, so the
|
||||
mismatch is a fact in the diagnostics rather than a picture that looks plausible.
|
||||
|
||||
Two things the v1 adapters deliberately do **not** do:
|
||||
|
||||
* they do not invent a displacement. The SDK's lift uses optical flow and a scale
|
||||
estimated from the mesh, which the design document calls "not a verified
|
||||
displacement calibration"; a millimetre field that was never calibrated is worse
|
||||
than no field, so ``displacement_sensor_m`` is ``None`` and the surface is
|
||||
coloured in place. The composer already handles an ``approximate`` displacement
|
||||
for when a verified one arrives;
|
||||
* they do not rescale or pad a field to fit. A field whose shape does not match the
|
||||
domain is a mismatch (`field_domain_mismatch`), not something to resize.

**做**：`FingerFrameAdapter`/`BoxFrameAdapter`、`SurfaceSampler`、`SceneComposer`

（`compose`/`rest_frame`）、`ThreeDCoordinator` 的双 mailbox 与 generation/过期拒绝、`submit` 的
|
||||
`accepted/replaced/stale/disabled/invalid` 语义。
|
||||
**做**：`sampling.SurfaceSampler`（向量化双线性采样、无效传播、`remap_to_domain` 走 unroll 映射）、
|
||||
`composer.SceneComposer`（采样 → 位移 → 重算法线；`rest_frame`/`build_rest_frame`）、

`ThreeDCoordinator`（双容量 1 mailbox、generation/会话/来源过期拒绝、单飞行合成、可见性与设置）、
|
||||
`adapters`（Finger/Box：`|flow|`、depth 响应、域检查与诊断，**不造位移**）。
|
||||
|
||||
**验收**：
|
||||
**验收（已通过）**：`shared/tests/test_scene3d_live.py` 25 项、`apps/studio/tests/test_scene3d_coordinator.py` 13 项、
|

`test_scene3d_adapters.py` 13 项；全部无需 GPU。
|
||||
|
||||
| 用例 | 通过标准 |
|
||||
| 用例 | 结果 |
|
||||
|---|---|
|
||||
| 采样正确性 | 常量场/斜坡/单点脉冲/NaN/遮罩场与 CPU 参考实现逐位一致 |
|
||||
| 无效语义 | 任一正权重点无效 ⇒ 该顶点无效；非有限 scalar 不显示为 0；参考帧 `scalar` 全不可用 |
|
||||
| 色标语义 | `display_gain` 只改显示位置：增大倍率前后 `scalar` 与力值逐位不变 |
|
||||
| 过期帧 | 旧 `generation`/`request_id` 永远不能覆盖新场景；`stale_frame` 安静丢弃并计数 |
|
||||
| 不阻塞采集 | 合成人为放慢 10 倍，`submit` 调用耗时 p99 < 1 ms，记录行数不变 |
|
||||
| 缺数据 | 无字段 → `no_data`，清掉旧测量颜色，允许显示参考模型 |
|
||||
| 采样正确性 | 常量/斜坡/单点脉冲与参考逐位一致；四点双线性与手算一致；2 万顶点采样 < 150 ms |
|
||||
| 无效语义 | 任一**正权** tap 无效 ⇒ 顶点无效且值为 NaN（不是 0）；未用 tap 不参与也不致无效；非有限 scalar 同样无效；**0.0 是有效值** |
|
||||
| 色标语义 | `display_gain` 1→50 后 `scalar`/`valid` 逐位不变，只有位置变（示例 1 mm → 50 mm） |
|
||||
| 示意形变标注 | `approximate` 位移产生 `display_illustrative`（info，含「×N」「illustration」）；`calibrated` 不产生；无位移时着色并报 `field_unavailable` |
|
||||
| 法线 | 从**形变后**位置重算；凸起处斜坡倾斜、顶点保持竖直、反向位移使斜坡反向倾斜；两条对角线顶点（与凸起不相邻）保持不变 |
|
||||
| 过期帧 | 旧 generation/来源/会话一律 `stale` 并计数；场景切换时正在跑的那次合成结果被丢弃 |
|
||||
| 不阻塞采集 | 合成放慢到 50 ms 时 `submit` p99 **< 1 ms**；200 帧只发生 ≤60 次合成；`max_in_flight == 1`（队列不会增长） |
|
||||
| 缺数据 | 无有效数据 → `no_data`，且呈现参考模型（scalar 全 NaN、`valid` 全假） |
|
||||
| 适配器 | 域不匹配时**发布空**并报出所见的两个形状；带 map 时按映射 gather，空洞为 NaN 且无效；结果只读、不与 packet 共享内存 |
|
||||
|
||||
**这一阶段抓到的**：
|
||||
|
||||
1. **换倍率需要"当前那一帧"**：原来用 `incoming.peek()` 重合成，而那一帧已被消费 → 倍率改了画面不变。
|
||||
现在协调器保留 `_last_field_frame`，倍率变化就重画**屏幕上那一帧**（而不是跳到一个更新的瞬间）。
|
||||
2. `display_illustrative` 不在诊断码表里 → 被默认成 `error`；已作为 `info` 加入码表。
|
||||
3. **对称凸起的顶点法线是竖直的**（我第一版测试断言它倾斜，等于断言一个 bug）；现在断言斜坡倾斜、顶点竖直，
|
||||
并且"与凸起不相邻的对角顶点不变"。
|
||||
4. `assets.py` 里还留着与 `package.py`/`legacy.py` 同名的**桩类**——阶段 2 实现后它们就成了会误导集成者的重复定义；
|
||||
现在 `assets.py` 是门面（re-export + `SceneCompiler`，加密请求明确拒绝并指向阶段 5）。
|
||||
|
||||
**明确未做**：手势/面板（阶段 4）；**示意位移的适配器接入**留到阶段 4——需要 SDK 的 lift 与一个已确认的尺度，
|
||||
现在适配器一律 `displacement=None`（宁可只着色，也不给未标定的毫米）。

The sampling table is built once, at load time, from the field's own domain. It is
|

never rebuilt per frame, and a vertex is never repaired by searching for the nearest
|

triangle: if any tap that carries weight is invalid, the vertex is invalid.
|
||||
|
||||
Three details that decide whether a measurement is honest:
|
||||
|
||||
* **an invalid tap is not zero.** Weighting a gap with weight 0 would still poison
|
||||
the sum, because ``0 * NaN`` is ``NaN``; invalid taps are therefore excluded from
|
||||
the sum and the *vertex* is marked invalid, which is what the shader draws as the
|
||||
neutral colour.
|
||||
* **validity is a separate array from the value.** A vertex whose scalar happens to
|
||||
be 0.0 is a measurement of zero; a vertex that is invalid has no value at all, and
|
||||
the value is left as ``NaN`` so nobody can mistake one for the other.
|
||||
* **the domain is checked, not assumed.** A frame whose domain or shape does not
|
||||
match the binding is refused with ``field_domain_mismatch`` rather than sampled
|
||||
into a plausible-looking but wrong picture.
