+## OSM 预检命令
+
+### 1. Scope / Trigger
+
+`preflight:area` 用于手工编辑 OSM 后、运行 QGIS / Blender / Cesium 前的快速结构门槛。
+它不是构建阶段,不进入 `build-area --stages`,不会启动外部工具或写场景产物。
+
+### 2. Signatures
+
+```bash
+npm run preflight:area
+npm run preflight:area -- --config config/areas/.json
+```
+
+### 3. Contracts
+
+- 通过 `readAreaConfig()` 读取区域配置,只读取配置文件和 OSM XML。
+- OSM 解析和错误分类来自 `scripts/lib/area-diagnostics.js`,不得另建 XML 解析器。
+- ``、``、`` 带 `action="delete"` 时属于历史删除对象,解析统计和
+ 几何检查必须忽略;否则旧 OSM 导出会把已删除的建筑误报为损坏面。
+- 无效 bounds、任意 way 缺失 node、破损 building way、破损 building multipolygon、
+ 不可解析为正米数的显式 building `height` 都是 error,并以非零退出。
+- 不填 `height` / `building:levels` 合法;无效 `building:levels` 是 warning。
+- 仅在 error 为零时原子写 `/_pipeline/stages/preflight.manifest.json`。失败不覆盖
+ 上次成功 manifest。manifest 记录 config / OSM 文件摘要、预检 summary、errors、warnings
+ 和耗时。
+- `diagnose:area` 显示该 manifest;`check:area` 仅在 manifest 存在时检查其有效性和
+ freshness,故采用前不会使旧区域质量门失败。
+
+### 4. Validation & Error Matrix
+
+| 条件 | 结果 |
+|---|---|
+| 无效 bounds、缺失 node、破损建筑几何、坏显式 height | 输出 error,非零,不覆盖旧 manifest |
+| 无效 `building:levels` | 输出 warning,仍可成功写 manifest |
+| `action="delete"` 的节点 / way / relation | 忽略,不计入当前 OSM 或报错 |
+| OSM / config 不存在 | `readAreaConfig()` 或文件读取抛错,非零 |
+
+### 5. Good/Base/Bad Cases
+
+- Good: 手工编辑后预检 PASS,再运行 `build-area` 的任意重型阶段。
+- Base: 未运行过预检的旧区域,`check:area` 仍可按既有规则通过。
+- Bad: 预检失败后仍更新 manifest,或把预检加入 `all` 导致每次构建修改验证记录。
+
+### 6. Tests Required
+
+- `npm run test:preflight`
+- `npm run preflight:area -- --config config/areas/nantaizi-lake-innovation-valley.json`
+- `npm run diagnose:area -- --config config/areas/nantaizi-lake-innovation-valley.json`
+- `npm run check:area -- --config config/areas/nantaizi-lake-innovation-valley.json`
+
+### 7. Wrong vs Correct
+
+Wrong:
+
+```js
+const xml = fs.readFileSync(area.input, "utf8");
+const missingNodes = xml.match(/]*ref=/g).length;
+```
+
+Correct:
+
+```js
+const osm = parseOsm(fs.readFileSync(area.input, "utf8"));
+const preflight = analyzeOsmPreflight(osm);

+# OSM area preflight design
+
+## Boundaries
+
+`scripts/lib/area-diagnostics.js` 保持 OSM 解析和预检分类的唯一事实源。新增 `scripts/preflight-area.js` 只负责 CLI 参数、报告和退出码;它不读取产物,也不调起外部工具。现有 `diagnose-area.js`、`check-area.js` 不复制预检逻辑。
+
+## Data Flow
+
+```text
+area config + OSM XML
+ -> analyzeOsmPreflight()/shared parseOsm()
+ -> { summary, errors, warnings }
+ -> preflight-area CLI report + exit code
+ -> successful preflight.manifest.json
+ -> diagnose/check manifest freshness reporting
+```
+
+预检 manifest 是一次成功验证的记录,不是输入所有权或构建依赖。它记录 config/OSM 文件摘要、错误/警告、统计和耗时;预检失败时不写入,也不删除旧 manifest,以保留最后一次成功记录。
+
+## Classification
+
+Blocking error 仅限肯定会使场景几何或范围不可靠的 OSM 结构错误:无效 bounds、任意 way 的缺失 node 引用、破损的建筑 way / building multipolygon。没有 `height` / levels 不是错误(渲染已有默认值);填写但不可解析的显式 `height` 是错误。`building:levels` 的非正值或不可解析值将作为 warning,除非现有 Blender 行为表明它会产生错误几何。
+
+## Compatibility
+
+现有 `diagnose:area` 保持全量只读报告;它添加 preflight manifest 一行。`check:area` 仅在 manifest 存在时才要求其有效和 fresh,确保现有历史构建仍可通过。新命令的默认配置规则与其他 area CLI 一致。
+
+## Rollback
+
+删除 `preflight:area` CLI、预检 manifest 定义和 diagnostics 展示即可回到当前行为。预检 manifest 是可再生文件,保留或删除均不影响构建。

+# Add OSM area preflight
+
+## Goal
+
+在调用 QGIS、Blender 或 Cesium 前,快速验证区域 OSM 是否包含会导致建筑或场景几何错误的人工编辑问题。使用者应得到明确的通过/失败结果和可定位的问题列表,而不必先跑重型构建阶段。
+
+## Confirmed Facts
+
+- `scripts/lib/area-diagnostics.js` 已是区域配置和 OSM 解析的事实源;它已覆盖 bounds、building multipolygon、缺失 node 引用及高度标签,并被 `diagnose:area` 和 `check:area` 共同复用。
+- `diagnose:area` 是全文诊断,包含既有产物、GLB 与 manifest;它不适合成为编辑 OSM 后的轻量独立门槛。
+- 当前 `nantaizi-lake-innovation-valley` 是唯一验证目标。忽略 `action=delete` 的历史对象后,其 OSM 有 1 个健康的建筑 multipolygon 和 23 个有效显式高度标签。
+- 全阶段 manifest 已存在;新预检不应被实现为 `build-area --stages` 的构建阶段。
+
+## Requirements
+
+1. 新增 `npm run preflight:area -- --config config/areas/.json`,只读取区域配置和 OSM XML;不得调用 QGIS、Blender、Cesium、压缩或写入场景产物。
+2. 从共享 diagnostics 模块提供结构化 OSM 预检结果,避免新增第二套 XML/建筑关系解析。
+3. 预检应检查:有效 bounds、way 引用的 node、building way 闭合性和最小节点数、建筑 multipolygon 的 outer/inner member、成员存在性、可拼接闭环,以及 building `height` / `building:levels` 的基本可解析性。
+4. 命令输出简短摘要、错误和警告;存在 blocking error 时以非零退出。
+5. 成功预检写 `/_pipeline/stages/preflight.manifest.json`,记录配置和 OSM 输入的文件摘要、预检摘要、errors 与 warnings。失败预检不得覆盖此前成功 manifest。
+6. `diagnose:area` 显示预检 manifest 的状态;`check:area` 仅在该 manifest 已存在时检查其新鲜度和有效性,避免使历史区域在首次采用前立即失败。
+7. README 和 Pipeline spec 记录命令、退出码与 manifest 所有权。
+
+## Acceptance Criteria
+
+- [x] 当前南台子 OSM 上 `npm run preflight:area -- --config config/areas/nantaizi-lake-innovation-valley.json` 输出 PASS、写入 fresh `preflight.manifest.json`,且不触发重型工具。
+- [x] 预检报告包含 buildings、multipolygon、bounds 和几何健康统计。
+- [x] 通过临时 OSM fixture 验证:缺失/无效 bounds、缺失 node、未闭合 building way、破损 building multipolygon、无效显式 height 都能得到定位明确的 blocking error。
+- [x] `diagnose:area` 显示 preflight manifest,`check:area` 对存在但 stale/invalid 的 preflight manifest 失败。
+- [x] 原有 `diagnose:area` 与 `check:area` 继续通过当前南台子区域。
+- [x] 修改脚本通过 Node 语法检查和 `git diff --check`。
+
+## Out Of Scope
+
+- 不修复 OSM 文件,不自动重组关系或补齐标签。
+- 不检查道路拓扑、转向箭头渲染、osm2streets 的语义兼容性,或任意非建筑面是否合法。
+- 不把预检加入 `build-area` 的默认阶段,也不要求未运行过预检的历史产物立即失败。
+- 不验证 `hanyang-block`。
+
+## Key Decisions
+
+- 缺失 node 引用一律作为 blocking error。它表示 OSM 引用完整性已损坏,即使当前出现在非建筑 way,也不将问题带入后续构建。
+
+## Notes
+
+- 这是跨 CLI、OSM 解析、质量门和 manifest 的改动,按复杂任务处理,需要 design 和 implement 工件后再开始实现。
