 build\wheel\win.bat
-.\build\wheel\docker\run.ps1
+.\build\wheel\docker\run.ps1 -SkipImageBuild   # reuse the image when only sources changed
 ```
 
+The image bakes in per-ABI build tooling and a per-ABI wheelhouse of the runtime
+deps, so the entrypoint no longer re-resolves them over the network. See
+`docs/publishing.md` §6 for build-time details, why `-SkipImageBuild` matters,
+and what to change before attempting to parallelize the per-ABI builds.
+
+### Release gate
+
+Local only: never publishes, and makes no network call unless `--check-pypi` is
+passed. See `docs/publishing.md` for the full flow.
+
+```bash
+python build/run.py release preflight --version <version>
+python build/run.py release preflight --all-wheel-pythons --check-pypi
+python build/run.py release audit SDK\<version>\orisys-<version>-cp312-cp312-win_amd64.whl
+```
+
+`preflight` runs: repo state → version consistency → version-string scan →
+duplicate guard (fails only when the version is already released: a local git
+tag, or PyPI with `--check-pypi`) → pytest → bundle precheck → per-wheel static
+content/metadata assertions → isolated runtime verification in one venv per wheel
+(imports + bundled assets + real frames, no camera). A populated `SDK/<version>/`
+is the expected input, so build first:
+
+```bash
+python build/run.py wheel-win
+python build/run.py release preflight --all-wheel-pythons --check-pypi
+```
+
+Reports land in `build/release/reports/<version>/`.
+
+### Publish
+
+Both default to a dry run; `--apply` is required for anything irreversible.
+
+```bash
+python build/run.py release auth                                   # credential status
+python build/run.py release auth --set-token pypi                 # hidden prompt, writes ~/.pypirc
+python build/run.py release github --version <version>            # preview
+python build/run.py release github --version <version> --apply    # sync + tag + push + Release
+python build/run.py release pypi   --version <version> --apply                  # TestPyPI only
+python build/run.py release pypi   --version <version> --confirm-pypi --apply   # + PyPI
+python build/run.py release pypi   --version <version> --pypi-only --apply      # skip TestPyPI
+```
+
+Both refuse to act unless `release preflight` passed on a clean commit with no
+waived options, and every wheel still hashes to what that report recorded.
+Tokens are only ever read from a hidden prompt or stdin, never from argv.
+See `docs/publishing.md` §3.

+"""Local release gate: everything that must hold before publishing a wheel.
+
+``release preflight`` answers one question with an exit code: is this checkout,
+this version and these wheels safe to publish? It never publishes anything, and
+by default it makes no network calls.
+
+Steps, in order:
+
+1. ``repo-state``           - git repository, clean working tree, recorded commit
+2. ``version-consistency``  - __version__ == pyproject dynamic attr == wheel names
+3. ``version-strings``      - no stale version literal left in tracked prose
+4. ``duplicate-guard``      - already-released version (git tag, optionally PyPI)
+5. ``tests``                - pytest (slow/hardware markers excluded)
+6. ``bundle-precheck``      - every bundle item resolves; required assets present
+7. ``wheel-inspection``     - static metadata/content assertions per wheel
+8. ``wheel-runtime``        - one isolated venv per wheel: bundled assets load and
+                              real frames flow through the public pipeline
+
+Output lands in ``build/release/reports/<version>/preflight.{json,txt}``, and is
+the contract the publish commands (``release github`` / ``release pypi``) consume:
+they refuse to ship anything this run did not certify.

+# 发布流程（构建 → 校验 → 发布）
+
+本文档说明如何构建 orisys 的 Nuitka 二进制 wheel、如何在发布前用一条命令做完整门禁，以及当前仍需人工执行的发布步骤。
+
+> 历史说明：`README.md` 与 `build/wheel/docker/run.ps1` 早就引用了本文件，但它此前并不存在。本文件补齐该引用。
+
+---
+
+## 0. 环境准备
+
+推荐用 `py310` conda 环境执行构建与校验（它同时具备 pytest / twine / numba / Nuitka / open3d / PyQt5）：
+
+```powershell
+conda activate py310
+python -m pytest -m "not slow and not hardware"   # 开发期快速回归
+```
+
+`py311`、`py312` 仅作为 Nuitka 各 ABI 的编译环境按需调用（`build/wheel/win.bat` 会依次使用 `py310`/`py311`/`py312`）。
+
+**不要**在同一个环境里既装旧版 `orisys` 又从源码目录跑测试：site-packages 里的旧包会静默遮蔽 `src/orisys`。
+`tests/test_harness_guards.py` 会显式报错提示执行 `pip uninstall -y orisys`。
+
+---
+
+## 1. 构建 wheel
+
+```powershell
+# Windows：py310 / py311 / py312 三个 ABI
+python build/run.py wheel-win
+
+# 单个解释器（当前环境）
+python build/run.py wheel
+
+# Linux manylinux（Docker Desktop，Linux 容器模式）
+python build/run.py manylinux
+python build/run.py wheel-manylinux -PythonVersions 3.10
+```
+
+产物落点：
+
+- `SDK/<version>/` — 交付用 wheel（git 忽略）
+- `dist/repaired/` — 上传候选（git 忽略）
+
+---
+
+## 2. 发布前门禁：`release preflight`
+
+```powershell
+# --version 可省略：默认取 pyproject 的 dynamic version（即 src/orisys/__init__.py 里的 __version__）
+python build/run.py release preflight
+```
+
+按顺序执行 8 个步骤，任一步失败即整体失败（`--keep-going` 可改为收集全部失败）：
+
+| 步骤 | 检查内容 |
+| --- | --- |
+| `repo-state` | 是 git 仓库、工作树干净、记录 HEAD（`--allow-dirty` 可豁免，用于提交前预检） |
+| `version-consistency` | `src/orisys/__init__.py::__version__` == pyproject 的 dynamic attr == `SDK/<version>/` 中 wheel 文件名里的版本 |
+| `version-strings` | 追踪的文本文件里没有与当前版本不符的版本字面量（见 §5.3） |
+| `duplicate-guard` | 该版本是否**已经发布过**：本地 git tag（`v<version>` / `<version>`，含 sibling `orisys-sdk-release` 仓库）命中即拒绝；`--check-pypi` 时再查 PyPI。`SDK/<version>/` 里已有 wheel 只作信息展示——那是 preflight 的正常输入，不是错误 |
+| `tests` | `pytest -m "not slow and not hardware"`（`--longrun` 时包含 slow） |
+| `bundle-precheck` | 每个 `[[tool.orisys.bundle.items]]` 至少解析出 1 个文件；finger 必需资产存在 |
+| `wheel-inspection` | 逐个 wheel 做静态断言：文件名/版本/METADATA 字段/RECORD 哈希/压缩包路径/体积上限/无 pyc 与缓存/无 `orisys/**/*.py` 源码泄漏/与源码树逐文件字节一致 |
+| `wheel-runtime` | 每个 wheel **一个** venv，在里面依次做：导入冒烟 → 内置 configs/sensors 资产可加载 → 对真实视频跑 40 帧公开流水线（无需相机、无 GUI） |
+
+正常顺序是**先构建、再 preflight**，不需要额外开关：
+
+```powershell
+python build/run.py wheel-win
+python build/run.py manylinux
+python build/run.py release preflight --all-wheel-pythons --check-pypi
+```
+
+提交前想先看结果（此时工作树通常还是脏的）：加 `--allow-dirty --keep-going`。
+
+产物报告：
+
+- `build/release/reports/<version>/preflight.json` — 机器可读，含每个 wheel 的 sha256，供后续发布步骤复用
+- `build/release/reports/<version>/preflight.txt` — 人工阅读
+- `build/release/reports/<version>/junit.xml` — pytest 结果
+
+（`build/release/reports/` 已加入 `.gitignore`。）
+
+### 常用参数
+
+| 参数 | 作用 |
+| --- | --- |
+| `--wheel-dir DIR` | 校验指定目录下的 wheel（默认 `SDK/<version>`） |
+| `--all-wheel-pythons` | cp310/cp311/cp312 各自在对应 conda 环境里独立校验 |
+| `--video PATH` / `--frames N` / `--config NAME` | 覆盖运行时校验输入（默认 `data/sample/s1_480p.mp4` / 40 帧 / `box`） |
+| `--offline` | 复用父环境的 numpy/opencv/numba，不去 PyPI 装依赖 |
+| `--check-pypi` | 唯一一处网络调用：只读 PyPI，防止重复发布 |
+| `--skip-tests` / `--no-runtime` / `--no-assets` | 显式跳过并在报告中留痕；**跳过的运行不能作为发布依据** |
+| `--report-dir DIR` | 覆盖报告根目录 |
+
+`wheel-runtime` **不会静默跳过**：找不到视频时直接失败，提示 `--video` / `ORISYS_VERIFY_VIDEO`。
+
+### 单体体检：`release audit`
+
+对单个 wheel 做静态断言（+ 可选运行时校验），不需要版本上下文。适合体检历史产物：
+
+```powershell
+python build/run.py release audit SDK\<version>\orisys-<version>-cp312-cp312-win_amd64.whl
+python build/run.py release audit dist\repaired\orisys-<version>-cp310-cp310-win_amd64.whl --strict-bundle
+
+# 追加运行时校验（--assets 与 --runtime 同时给时共用一个 venv，只装一次依赖）
+python build/run.py release audit <wheel> --assets --runtime --video data/sample/s1_480p.mp4
+```
+
+默认对「内置文件与当前源码树不一致」只告警（历史 wheel 与当前分支不一致是正常的）；加 `--strict-bundle` 改成失败（刚构建完的 wheel 应当一致）。
+
+旧的导入冒烟测试仍然可用，行为不变：
+
+```powershell
+python build/run.py verify <wheel>
+python build/run.py verify <wheel> --contents          # 静态断言
+python build/run.py verify <wheel> --assets --runtime  # 资产 + 真实帧
+python build/run.py verify --gui-dist --product ory_finger
+```
+
+---
+
+## 3. 发布（两条命令）
+
+先决条件：`release preflight` PASS，**而且是在干净提交上跑的**。两个发布命令都只发布「preflight 认证过的东西」——它们会读取 `build/release/reports/<version>/preflight.json`，逐个核对 wheel 的 sha256，并拒绝使用带豁免项（`--skip-tests` / `--allow-dirty` / `--no-runtime` / `--force`）的报告。所以正确顺序是：
+
+```powershell
+git add -A; git commit -m "..."
+python build/run.py wheel-win && python build/run.py manylinux
+python build/run.py release preflight --all-wheel-pythons --check-pypi   # 干净树 + 无豁免
+```
+
+两个命令**默认都是 dry run**，只打印将要执行的动作；必须显式加 `--apply` 才会真正动手。GitHub 的 `gh release create`、`git push`，以及 PyPI 上传（版本号永久占用、不可覆盖）都属于不可撤销操作。
+
+### 3.1 GitHub：同步公开仓库 + 上传 Release
+
+```powershell
+python build/run.py release github --version 0.5.2              # 预览
+python build/run.py release github --version 0.5.2 --apply      # 执行
+```
+
+执行顺序：
+
+1. 认证书校验（上面那份报告 + 逐 wheel sha256）
+2. `git fetch --tags`，若 `v0.5.2` 或 `0.5.2` 已存在则拒绝；`gh release view` 已存在也拒绝
+3. 按 `tools/downstream_sync_manifest.json` 同步公开内容到 `../orisys-sdk-release`，并运行 manifest 里的 `checks`
+4. 把 `SDK/0.5.2/*.whl` 放到 `orisys-sdk-release/release/0.5.2/`（该目录在 release 仓库里是 gitignore 的，只用于上传附件）
+5. 提交 → 打 tag `v0.5.2` → push 分支与 tag
+6. `gh release create v0.5.2 --verify-tag --latest <6 个 wheel>`，然后回读 `gh release view --json assets` 核对附件齐全
+
+需要：`gh` 已安装并登录（`winget install --id GitHub.cli` 然后 `gh auth login`）。没装 gh 时：
+
+- dry run 仍会完整打印计划（只告警）
+- `--apply` 会失败，或改用 `--skip-release-upload`：同步、提交、打 tag、push 都自动完成，然后打印出你自己要跑的 `gh release create`
+
+其他开关：`--notes-file`（自定义 release notes）、`--attach-preflight`（把 `preflight.json` 也作为附件上传，便于审计；注意报告里有本机绝对路径）、`--allow-dirty-release`、`--skip-fetch`、`--skip-checks`。
+
+> tag 拼写沿用历史风格 `v<version>`（注意历史里那个 typo tag `0.50` 指向 `v0.5.1`）。命令会在动手前拒绝已存在的 tag，所以不会重复发布。**如果 tag 已经 push 但 Release 上传失败（例如 `gh` 没配好），直接重跑同一条 `--apply` 命令即可续跑**：它会跳过创建 tag，只补做剩下的步骤；只有「GitHub Release 已存在」才拒绝。
+
+### 3.2 PyPI：TestPyPI 先行，确认后再上正式仓库
+
+```powershell
+python build/run.py release pypi --version 0.5.2                          # 预览
+python build/run.py release pypi --version 0.5.2 --apply                  # 只发 TestPyPI
+python build/run.py release pypi --version 0.5.2 --confirm-pypi --apply   # TestPyPI + 正式 PyPI
+
+# 只有正式 token、没有 TestPyPI 账号时：跳过彩排直接发正式库
+python build/run.py release pypi --version 0.5.2 --pypi-only --apply
+```
+
+`--pypi-only` 与 `--confirm-pypi` 互斥。**注意它的代价**：没有 TestPyPI 彩排，而正式库的版本号一旦占用就无法复用、无法替换。它仍然会做完整门禁、`twine check`、上传前查重、上传后回读索引核对文件、以及把产物重新拉回来验证。
+
+执行顺序：
+
+1. 认证书校验（与 `release github` 同一份报告）
+2. `twine check` 全部 wheel（校验 METADATA/long description，上传前就能发现问题）
+3. 只读查询目标索引，确认该版本不存在（TestPyPI 与 PyPI 各查各的）
+4. 上传 → **轮询**索引确认 6 个文件都在 → `pip download` 把刚上传的 wheel 拉回来，证明产物可获取
+5. 未加 `--confirm-pypi` 时只发 TestPyPI，然后停在这里并打印后续命令
+
+两个针对「索引不即时一致」的设计（TestPyPI 尤其明显，上传成功后 JSON API 可能滞后若干秒）：
+
+- **上传后的确认会重试**（默认 6 次 × 5 秒）。确认不了也**不算失败**：twine 上传成功就说明产物已发布，命令会打印警告、给出项目页链接并以 0 退出，不会把一个成功的上传报成失败。真正的失败只有两种：twine 上传本身失败，或索引上的文件集与本地不一致。
+- **重复运行是安全的**：若索引上已经存在该版本且文件集完全一致，该阶段会被视为「已完成」而跳过（`[ok] testpypi already serves orisys 0.5.2 with all 6 file(s)`），不会重传、也不报错。这让你在确认不明确时可以直接重跑。如果文件集**不一致**（索引上是另一次构建），才会失败并停下。
+
+所以「上传后确认失败」不等于要重新上传——索引版本号不可覆盖，重跑只会做一次只读核对。
+
+### 3.3 凭证：`release auth` 与 `~/.pypirc`
+
+```powershell
+python build/run.py release auth                        # 查看两个索引的凭证状态
+python build/run.py release auth --set-token pypi       # 隐藏输入，写入 ~/.pypirc
+python build/run.py release auth --set-token testpypi
+python build/run.py release auth --repair               # 修「有段但没列进 index-servers」
+```
+
+`--set-token` 的 token 只从**隐藏输入**或 `--token-stdin`（供脚本/CI）读取，**不接受命令行参数**——避免落进 shell 历史和进程列表。写入采用定点文本编辑，文件里的说明注释会保留；同时会把该索引补进 `[distutils] index-servers`（这一步很关键，见下）。
+
+`release auth` 只有在你真的运行 `--set-token` 时才写文件；不带参数时只读并报告，状态判断比「文件是否存在」严格：
+
+```
+config file: C:\Users\cheun\.pypirc (exists)
+[--  ] [pypi] not usable: [pypi] still contains a placeholder token
+[--  ] [testpypi] not usable: C:\Users\cheun\.pypirc has no [testpypi] section
+```
+
+**占位符、空密码、`username` 不是 `__token__`，都会被判定为「不可用」**——否则 twine 只会在真正上传时才发现，而那时已经动过索引了。
+
+`release pypi` 在 `--apply` 时若凭证缺失：有终端就地提示输入（隐藏），无终端则直接失败并打印 `release auth --set-token <index>`；也可显式加 `--prompt-credentials`。dry run 只告警并继续展示计划，不会卡在输入上。
+
+#### twine 直接读取的格式
+
+默认路径 `~/.pypirc`（Windows 上即 `C:\Users\<你>\.pypirc`，由 `USERPROFILE` 展开）。**没有**环境变量可以改这个路径；要用别的文件就传 `--config-file`。
+
+```ini
+[distutils]
+index-servers =
+    pypi
+    testpypi
+
+[pypi]
+repository = https://upload.pypi.org/legacy/
+username = __token__
+password = pypi-你的正式token
+
+[testpypi]
+repository = https://test.pypi.org/legacy/
+username = __token__
+password = pypi-你的TestPyPI token
+```
+
+容易搞错的点：
+
+- **`[distutils] index-servers` 必须列出该索引，否则 twine 完全忽略那一节** —— 这是最常见的坑：文件里明明有 `[testpypi]` 段，twine 却报 `InvalidConfiguration: Missing 'testpypi' section`。用 `release auth --repair` 修（把已存在但未列出的段补进 `index-servers`）。
+- 更细的语义差别：`index-servers =` **值为空**表示「一个都不认」；只有**整行缺失**时 twine 才会回退到默认的 `pypi testpypi`。所以手工编辑时别把名字删空。
+- `username` 就是字面量 `__token__`，不是账号名或邮箱
+- 两类 token **都以 `pypi-` 开头**，但**不能互换**：拿正式 token 打 `test.pypi.org` 会被 403 拒绝
+- TestPyPI 是**独立服务、独立账号**，注册在 <https://test.pypi.org/account/register/>，你的 PyPI 账号在那里不存在
+- 正式 token 建议限定到 `orisys` 项目（项目已存在，可以建 project-scoped token）
+- 该文件必须在**任何 git 仓库之外**（放在用户目录里）；token 一旦提交进仓库，即使后来删文件也还在历史里——那属于安全事故
+- 临时替代方案：会话内设 `TWINE_USERNAME=__token__` + `TWINE_PASSWORD=<token>`，命令会识别这种情形
+- PyPI token **没有只读的校验方式**，有效性只能在真正上传时才会被索引确认；所以所有本地检查、查重都排在写操作之前
+
+`release auth` 的「可用」判定**直接问 twine 自己**（`twine.utils.get_config` 解析出的 username/password），而不是自己解析 ini，这样报告结果与 twine 的行为不会分叉。twine 未安装时才回退到本地复刻同一套规则。
+
+只需要 TestPyPI 时才把 `testpypi` 写进 `index-servers` 并填对应 token；只发正式库时 `--pypi-only` 用不到 `[testpypi]` 段。
+
+### 3.4 已知的历史发布空洞

+
+## 4. 环境变量
+
+| 变量 | 用途 |
+| --- | --- |
+| `ORISYS_TEST_VIDEO` | pytest 用的视频；默认自动取 `data/sample/s1_480p.mp4` |
+| `ORISYS_TEST_CONFIG` | pytest 用的配置名；默认自动挑一个含 `stitcher.box_size` 的配置 |
+| `ORISYS_VERIFY_VIDEO` | 运行时校验用的视频 |
+| `ORISYS_VERIFY_CONFIG` | 运行时校验用的配置名（默认 `box`） |
+| `ORISYS_LONGRUN_BACKEND` / `ORISYS_LONGRUN_FRAMES` | `slow` 长稳测试的参数 |
+| `CONDA_ENVS_ROOT` | conda envs 根目录（`--all-wheel-pythons` 用它解析 `py310`/`py311`/`py312`） |
+
+---
+
+## 5. 三个必须记住的坑
+
+### 5.1 Nuitka 编译包的 `__file__` 是假的
+
+Nuitka 把整个 `orisys` 编译成单个扩展模块，其 `__init__` 会安装 `nuitka_module_loader`。于是：
+
+```python
+>>> import orisys
+>>> orisys.__file__          # 合成的、磁盘上并不存在的路径
+'...\\site-packages\\orisys\\orisys\\__init__.py'
+>>> orisys.__path__          # 第二项是 Nuitka 的哨兵值
+['...\\site-packages\\orisys\\orisys', '\\not_existing']
+>>> orisys.__loader__.__class__.__name__
+'nuitka_module_loader'
+```
+
+后果：**在 Nuitka wheel 里不能靠 `orisys.__file__` 或 `importlib.resources.files("orisys")` 定位内置数据**——它们会指向不存在的目录，静默返回「文件不存在」。请改用发行包定位：
+
+```python
+from importlib.metadata import distribution
+root = distribution("orisys").locate_file("orisys")   # site-packages/orisys
+```
+
+`build/common/verify/wheel.py` 的内置资产校验就是这么做的，并且会显式断言该目录位于校验用 venv 内，避免被父环境里的旧 `orisys` 顶替。
+
+### 5.2 `--offline` 会被父环境的脏安装污染
+
+`--offline` 通过 venv 的 `--system-site-packages` 复用父环境的 numpy/numba 等依赖，这也顺带暴露了父环境里的 `orisys`。若父环境残留了半卸载的 editable 安装（典型症状是 `pip` 提示 `Ignoring invalid distribution -risys`，且 `site-packages/orisys/__init__.py` 是一个指向死路径的 shim），校验就会读到它。
+
+处置：在构建环境里执行 `pip uninstall -y orisys`，或改用不带 `--offline` 的完全隔离 venv（会联网安装依赖）。
+
+### 5.3 版本号只有一个地方，其他都是推导出来的
+
+版本号的唯一来源是 **`src/orisys/__init__.py::__version__`**。以下全部由它推导，不需要手改：
+
+| 产物 | 推导方式 |
+| --- | --- |
+| pyproject 的 `[project] version` | `[tool.setuptools.dynamic] version = {attr = "orisys.__version__"}` |
+| wheel 文件名里的版本 | `build/wheel/build.py` 调 `get_version()` |
+| wheel `METADATA` 的 `Version:` | 生成的 `setup.py` 里写入同一个 `version` |
+| `SDK/<version>/` 目录名 | 同上 |
+| `importlib.metadata.version("orisys")` | 从 wheel METADATA 读出 |
+
+因此**不要**再往文档、示例、测试里写具体版本号：
+
+- 用法示例写 `SDK/<version>/...`、`--version <version>`，不要写具体版本
+- 文档里不要写「版本：x.y.z」；需要时让用户用 `python -c "import orisys; print(orisys.__version__)"` 自己看
+- 示例脚本的 docstring 不要再写 `SDK version: x.y.z`
+- 测试里需要「一个版本」时用明显是假的版本号（如 `1.x.y` 这种不会与真实版本混淆的值），不要用当前版本 —— 否则每次发版都要改测试，而且一次全局替换就会悄悄改坏断言
+
+`release preflight` 的 `version-strings` 步骤强制这条规则：扫描所有被追踪的文本文件，任何与当前版本不符的版本字面量都会导致失败（`tests/` 与生成物除外；依赖约束如 `numpy>=1.24.4` 由正则排除）。
+
+历史记录属于例外，需显式登记在 `build/release/version.py::VERSION_STRING_ALLOWLIST` 里——登记本身就是「该字面量故意不是包版本」的文档。**不要用全局替换修改含历史版本的文件**：本文件的发布记录表就曾被一次全局替换改错（`0.50` typo tag 被挂到错误的版本上，`0.5.1` 那一行被覆盖丢失）。
+
+### 5.4 wheel 里有什么、没有什么
+
+打包内容由 `pyproject.toml` 的 `[[tool.orisys.bundle.items]]` 单点定义：
+
+| 内容 | 是否进 wheel | 说明 |
+| --- | --- | --- |
+| `config/*.json` | 是 | `orisys/configs/`，运行时配置解析要用 |
+| `sensors/**` | 是 | `orisys/sensors/`，含 finger 的 npz/npy 资产，运行时与 GUI 都要用 |
+| `examples/**` | 是 | `orisys/examples/`，用户装完就能跑示例 |
+| `docs/**` | **否** | 只随 GitHub 仓库与 PyPI 项目页提供。`docs/publishing.md` 是内部流程文档；`docs/pypi_readme.md` 仅在构建时被读取作为 long description |
+
+因为 docs 不进 wheel，**改文档不会让已构建的 wheel 失效**，不需要重新构建。（改 `examples/`、`config/`、`sensors/` 会——它们确实在 wheel 里，`wheel-inspection` 的 `bundle-fidelity` 会报出来。）
+
+如果以后需要离线 API 参考，加一个只包含 `docs/api.md` 的窄条目即可，不要整个 `docs/` 都塞进去。
+
+---
+
+## 6. 缩短 manylinux 构建时间
+
+`python build/run.py manylinux` 走 `build/wheel/docker/run.ps1` → 容器内 `entrypoint.sh`，对 `cp310/cp311/cp312` **串行**各做一次 Nuitka 编译 + 打 wheel + auditwheel repair + 隔离 venv 校验。
+
+### 6.1 镜像里已经烘好的东西（所以每次构建不必再拉）
+
+`Dockerfile.manylinux` 在每个 ABI 下预置了两类内容：
+
+1. **构建工具**：`pip`/`setuptools`/`wheel`/`nuitka`/`ordered-set`/`zstandard`/`auditwheel`。
+   因此 `entrypoint.sh` 默认**不再**在每个 ABI 上重跑 `pip install --upgrade pip setuptools wheel auditwheel` —— 那是每次构建 3 次多余的 PyPI 往返，还会让容器里的工具版本与镜像不一致。需要用最新工具时显式开启：
+
+   ```powershell
+   docker run ... -e ORISYS_UPDATE_BUILD_TOOLS=1 ...
+   ```
+
+2. **每个 ABI 一个 wheelhouse**（`/opt/orisys-wheelhouse/<tag>`），内含 `numpy`/`scipy`/`opencv-python`/`numba` 及其依赖闭包，外加 `pip`/`setuptools`/`wheel`/`auditwheel` 的 wheel。
+
+   `--target pypi-linux` 会**强制**校验：为每个 ABI 建一个一次性 venv，再 `pip install` 刚构建的 wheel 和它声明的运行期依赖。镜像故意不把运行期依赖装进解释器（用户是凭 wheel 元数据装的），所以以前每次构建都要现下约 200 MB × 3。`entrypoint.sh` 现在用 `PIP_NO_INDEX=1` + `PIP_FIND_LINKS=<wheelhouse>` 把 pip 指向本地 wheelhouse：**venv 仍然是隔离的**（没有 `--system-site-packages`），依赖解析与安装依然真实发生，只是不走网络。
+
+   找不到 wheelhouse 时会打印警告并回退到联网，不会静默失败。镜像因此增大约 400–500 MB（一次性代价，换每次构建省三次下载）。
+
+### 6.2 不要为了省事直接重建镜像
+
+只改了源码（`src/`、`config/`、`sensors/`、`examples/`、`pyproject.toml`）时加 `-SkipImageBuild`：
+
+```powershell
+.\build\wheel\docker\run.ps1 -SkipImageBuild
+```
+
+Dockerfile 的 `RUN` 层要装 3 份工具链并下载 3 个 wheelhouse，缓存未命中就是数分钟。**改了 `Dockerfile.manylinux` 或需要更新 wheelhouse 时才重建镜像**。
+
+### 6.3 Nuitka 的排除列表必须完整
+
+`build/wheel/compile.py::NUITKA_NOFOLLOW_IMPORTS` 列出所有**不打进 wheel、运行期从用户环境解析**的第三方包。漏一个意味着 Nuitka 会尝试把它跟进来：编译时间暴涨，而且 wheel 内容开始取决于构建机上恰好装了什么 —— `torch`、`torchvision`（`src/orisys/tracker.py` 的 RAFT 追踪器）和 `pyvkfft`（`backend_availability.py`）就是这样漏掉的，之前只是靠「构建机上没装」才没出事。
+
+`tests/test_nuitka_nofollow.py` 会扫描 `src/orisys` 的全部第三方导入，任何不在排除列表里的都会让测试失败。**新增可选依赖时同步更新列表。**
+
+### 6.4 想要并行？先读这一段
+
+`--jobs` 的默认值是**全部 CPU 数**，单次编译的 C 阶段已经吃满所有核心。真正能靠并行省下的是 Nuitka 的单线程前端（分析/优化/代码生成）、scons 启动、`auditwheel` 与 venv 校验 —— 做法是 3 路并行 + 每个 build 限 `--jobs=<核数/3>`。
+
+但**现在不能直接并行**：`build/common/paths.py` 里的工作目录是写死的共享路径
+
+```
+build/nuitka/compile
+build/nuitka/wheel
+build/nuitka/wheel/repaired
+```
+
+而 `build/wheel/build.py` 每次开头都 `_reset_dir()`（`rmtree`）这两个目录，`auditwheel repair` 又会再 `rmtree` 一次 `repaired`。仓库是挂载进容器的（`-v ${RepoRoot}:/src`），所以无论「一个容器 3 路并行」还是「3 个容器并行」，只要共享同一个挂载点，三个 build 就会互相清空暂存目录 —— 表现为随机失败或 wheel 内容错乱。
+
+要并行必须先让工作目录带上 ABI 标签（如 `build/nuitka/<tag>/compile`）。输出路径不用动：`SDK/<version>/`、`dist/repaired/` 的文件名本来就按 ABI 区分，下游 `release preflight` 不受影响。另外 3 个 Nuitka 并行很吃内存，先把 Docker Desktop 内存调到 16 GB 以上再试。

+# Orisys SDK
+
+叠动科技视触觉传感器配套的 Python SDK，提供图像采集、拼接、稠密光流、Helmholtz-Hodge 分解、接触与深度估计，以及可运行的示例。
+
+本文件是 PyPI 项目描述（`long_description`）的源文件：构建时由 `docs/publishing.md` 所述流程从**检出目录**读取（`build/wheel/package.py::PYPI_README_RELPATH`），**不会**被打进 wheel。因此不要在这里写内部仓库布局、构建流水线或发布步骤——那些内容属于仓库内的 `README.md` 与 `docs/publishing.md`。
+
+```bash
+python -m pip install orisys
+```
+
+支持 Python 3.10 / 3.11 / 3.12，Windows x64 与 Ubuntu x64。
+
+## 快速开始
+
+```bash
+python -c "import orisys; print(orisys.__version__)"
+python -c "import orisys; print(orisys.list_config())"
+```
+
+## 安装选项
+
+- `orisys` — CPU / 基础流程
+- `orisys[gui]` — Qt / Open3D 可视化示例
+- `orisys[cuda12]` / `orisys[cuda13]` — NVIDIA GPU 加速
+- `orisys[gui,cuda12]` — GUI + CUDA 12
+
+`orisys[cuda]` 与 `orisys[cuda12]` 等价。
+
+## 配置
+
+配置解析顺序：
+
+1. 显式 JSON 文件路径
+2. 内置配置名（`box`、`mini`、`finger` 等）
+3. 产品别名（如 `dd02` -> `dd02-ov`）
+4. 向后兼容的 JSON `"name"` 匹配
+
+```python
+import orisys
+
+sensor = orisys.Sensor(0, config_name="box")
+orisys.export_config("box", "./exported_config.json")
+```
+
+## 示例
+
+示例随 wheel 一起分发，位于 `orisys/examples/`。也可以从项目仓库获取：
+
+```bash
+python examples/basic_pipeline.py -v 0 -c box
+python examples/finger_pipeline.py --camera_id 0 --config finger
+```
+
+无相机时可以改用视频文件：
+
+```bash
+python examples/finger_pipeline.py --video ./sample.mp4 --config finger
+```
