+# 算法交付与测量结果输出规范
+
+版本：1.0.0
+状态：自 2026-08-13 起，新交付算法必须遵循；存量算法逐步迁移。
+适用范围：`alg/` 下所有向宏量点云处理平台输出测量结果的算法。
+
+## 1. 目的
+
+本规范统一算法 `result.json` 中正式测量结果的表达，解决以下问题：
+
+- 任务号被写在名称字符串里，例如 `任务46_车体横断面对角线差值`；
+- 同一任务的多个测量位置无法分组，例如任务 5 的左梁和右梁；
+- 头车、中车使用不同任务号，但结果中没有检测对象上下文；
+- `dx_y`、`dx_z` 等计算中间量混入正式测量结果；
+- 前端只能解析中文名称，无法稳定排序、筛选、统计和生成报告。
+
+平台进程、进度事件、产物文件等接入方式仍参考
+[`docs/algorithm-integration-spec.md`](../../docs/algorithm-integration-spec.md)。涉及测量结果字段时，**以本规范为准**。
+
+## 2. 基本原则
+
+1. **任务号结构化**：正式测量项必须提供 `taskNo`，不得只写进 `name`。
+2. **名称不编码**：`name` 只写项目名称，不包含 `任务XX_`、左右位置或车型前缀。
+3. **指标编码稳定**：每项结果必须有稳定的 `metricCode`，程序关联以它为准，不能依赖中文名称。
+4. **一个测量值一条记录**：同一任务存在左/右、前/后等多个结果时，保留多条记录并使用 `position` 区分，`taskNo` 相同。
+5. **正式结果与中间量隔离**：只有可交付、可判定、可进入报告的值才能进入 `measurements`；中间量放入 `extra.intermediateMetrics`。
+6. **不猜任务号**：任务号必须来自经确认的业务任务清单。无法确定时应阻止正式交付并请求确认，不能按数组序号或名称相似度推断。
+7. **值和单位分离**：`value` 必须是 JSON 数值或 `null`；禁止输出 `"0.073/700mm"` 这样的混合字符串。
+8. **JSON 必须标准合法**：禁止 `NaN`、`Infinity`；失败且无有效值时使用 `null`。
+
+## 3. 职责边界
+
+### 3.1 业务/产品负责人
+
+- 提供并确认正式任务清单：`taskNo`、项目名称、适用检测对象、理论值、公差、单位；
+- 审批任务号变更，算法工程师不得自行重新编号。
+
+### 3.2 平台/集成人员
+
+- 在算法输入或适配层提供 `inspectionObject`，例如 `head`（头车）、`middle`（中车）；
+- 将经确认的业务任务清单配置为映射表；
+- 校验最终 `result.json`，不让缺少任务号的正式结果进入业务表格。
+
+### 3.3 算法工程师
+
+- 为算法指标定义稳定的 `metricCode` 和准确的 `name`；
+- 输出 `position` 等算法能够确定的测量位置；
+- 在已获得检测对象和任务映射时输出正确的 `taskNo`；
+- 只把最终可交付结果放进 `measurements`，中间量放进 `extra.intermediateMetrics`；
+- 交付前运行本目录的校验脚本。
+
+> 最终写入平台的 `result.json` 必须满足本规范。若算法核心包不负责业务任务号，平台薄适配层必须在写出 `result.json` 前补齐，不能交给前端猜测。
+
+## 4. 顶层结构
+
+```json
+{
+  "schemaVersion": 1,
+  "measurementContractVersion": "1.0",
+  "status": "completed",
+  "message": "测量完成",
+  "context": {
+    "inspectionObject": "head",
+    "inspectionObjectName": "头车"
+  },
+  "measurements": [],
+  "extra": {
+    "intermediateMetrics": []
+  }
+}
+```
+
+字段说明：
+
+| 字段 | 必填 | 说明 |
+|---|---:|---|
+| `schemaVersion` | 是 | 平台插件结果版本；当前平台存量插件仍使用 `1` |
+| `measurementContractVersion` | 是 | 本测量结果规范版本，当前固定为 `"1.0"` |
+| `status` | 是 | `completed` 或 `error` |
+| `message` | 否 | 面向用户的简短说明 |
+| `context` | 有对象差异时必填 | 本次测量的业务上下文 |
+| `measurements` | 完成时必填 | 正式测量结果；允许空数组，不允许混入调试指标 |
+| `extra` | 否 | 算法报告、质量信息、中间量等非正式结果 |
+
+`schemaVersion` 与 `measurementContractVersion` 含义不同，不得互相替代。
+
+## 5. 正式测量项 `measurements[]`
+
+推荐完整结构：
+
+```json
+{
+  "taskNo": "5",
+  "metricCode": "underframe.longitudinal_beam.vertical_deflection",
+  "name": "纵向梁到直线的垂直偏差（挠度）",
+  "position": "左梁",
+  "value": 0.265,
+  "unit": "mm",
+  "tolerance": 7.0,
+  "toleranceLabel": "±7 mm",
+  "status": "pass"
+}
+```
+
+| 字段 | 必填 | 类型/取值 | 说明 |
+|---|---:|---|---|
+| `taskNo` | 是 | 字符串 | 正式业务任务号；即使全是数字也必须用字符串 |
+| `metricCode` | 是 | 字符串 | 稳定指标编码，建议 `<域>.<部件>.<指标>`，仅用小写字母、数字、点、下划线和短横线 |
+| `name` | 是 | 字符串 | 纯项目名称，不带 `任务XX_` 和位置前缀 |
+| `position` | 多位置时必填 | 字符串 | 如 `左梁`、`右梁`、`一位端`；不适用时省略 |
+| `value` | 是 | 数值或 `null` | 测量值；无有效结果时为 `null` |
+| `unit` | 有量纲时必填 | 字符串 | 如 `mm`、`°`、`%`；无量纲使用 `"1"` |
+| `theoreticalValue` | 否 | 数值 | 理论值，与 `unit` 相同 |
+| `baseline` | 斜率形式时必填 | 正数 | 基准长度，单位为 mm |
+| `tolerance` | 简单对称公差时使用 | 非负数 | `±tolerance`，与 `unit` 相同；斜率形式表示分子公差 |
+| `toleranceLower` | 非对称公差时使用 | 数值 | 相对理论值的下偏差 |
+| `toleranceUpper` | 非对称公差时使用 | 数值 | 相对理论值的上偏差 |
+| `toleranceLabel` | 复杂公差时使用 | 字符串 | 报告展示原文，例如 `+8.5/-3 mm` |
+| `status` | 是 | `pass` / `warning` / `fail` | 正式结果不得使用 `info` |
+| `qualityFlags` | 否 | 字符串数组 | 质量告警代码，不替代 `status` |
+
+约束：
+
+- 同一 `taskNo + metricCode + position` 在一次结果中必须唯一；
+- `name` 不得匹配 `^任务\s*\d+`；
+- `status=pass|warning|fail` 必须基于已确认的公差规则；
+- `value=null` 时不得判为 `pass`；
+- 若尚未获得正式任务号，该项不得进入最终 `measurements`。
+
+## 6. 检测对象与任务号映射
+
+当同一指标在不同检测对象上对应不同任务号时，必须先根据 `context.inspectionObject` 选择任务号。
+
+本次已确认的映射如下：
+
+| 检测对象 | 指标 | `taskNo` |
+|---|---|---:|
+| 任意 | 纵向梁到直线的垂直偏差（左、右挠度） | 5 |
+| 头车 `head` | 车钩面板到参考面的右偏转角 | 8 |
+| 中车 `middle` | 车钩面板到参考面的右偏转角 | 9 |
+| 头车 `head` | 车钩面板到纵向中心的右偏转角 | 10 |
+| 中车 `middle` | 车钩面板到纵向中心的右偏转角 | 12 |
+
+任务 5 的左右梁应输出两条记录：两条的 `taskNo` 和 `metricCode` 相同，`position` 分别为 `左梁`、`右梁`。
+
+如果输入中没有头车/中车信息，车钩算法不得自行默认成头车；应报契约错误，或由平台适配层在具备检测对象信息后完成映射。
+
+## 7. 斜率形式与角度值
+
+车钩“右偏转角”目前存在两种可能的交付口径，必须由业务任务清单明确：
+
+### 7.1 以角度交付
+
+```json
+{
+  "value": 0.0063,
+  "unit": "°",
+  "tolerance": 0.08
+}
+```
+
+### 7.2 以偏差值/基准长度交付
+
+```json
+{
+  "value": 0.073,
+  "unit": "mm",
+  "baseline": 700,
+  "tolerance": 1.0,
+  "toleranceLabel": "1/700 mm"
+}
+```
+
+禁止把 `value` 写成字符串 `"0.073/700mm"`。角度值和换算后的偏差值不能共用同一个 `metricCode`；如两者都需保留，一个作为正式结果，另一个放入中间量并使用不同编码。
+
+## 8. 中间数据与诊断数据
+
+以下数据通常不属于正式测量项：拟合系数、法向量、点数、残差、`dx_y`、`dx_z`、`D_y`、`D_z`、ICP fitness、RMSE 等。
+
+统一放入：
+
+```json
+{
+  "extra": {
+    "intermediateMetrics": [
+      {
+        "metricCode": "coupler.panel.dx_y_max",
+        "name": "Y 方向计算用最大 X 偏差",
+        "value": 0.0101,
+        "unit": "mm"
+      }
+    ]
+  }
+}
+```
+
+中间量：
+
+- 不需要 `taskNo`；
+- 不设置业务 `status` 和公差；
+- 不进入“算法结果”项数、合格率和正式报告；
+- 可用于日志、排障和算法复核。
+
+## 9. 禁止的旧写法
+
+```json
+{
+  "measurements": [
+    { "name": "任务46_车体横断面对角线差值", "value": 0.592 },
+    { "name": "左梁 · 纵向梁到直线的垂直偏差（挠度）", "value": 0.265 },
+    { "name": "最大 x 偏差 dx_y", "value": 0.010, "status": "pass" }
+  ]
+}
+```
+
+问题分别是：任务号嵌入名称、位置嵌入名称、中间量冒充正式结果。
+
+正确写法见 [`examples/head-car-coupler-and-deflection.result.json`](examples/head-car-coupler-and-deflection.result.json)。
+
+## 10. 兼容与迁移
+
+- 本规范是**目标输出契约**。当前平台前端尚未使用所有新增字段时，也必须保留这些字段，不能因此退回名称拼接方案；
+- 存量 `任务46_xxx` 等结果允许历史回放，但算法下一版本应拆为 `taskNo="46"` 和纯 `name`；
+- 平台适配层可以暂时从经确认的旧配置中迁移任务号，但不得长期正则解析中文名称；
+- 修改任务号、单位、换算口径、公差或 `metricCode` 均属于接口变更，必须在算法版本说明中记录；
+- 核心计算方法未变、只调整输出结构时，也应至少提升算法补丁版本并注明“输出契约迁移”。
+
+## 11. 交付检查清单
+
+算法工程师提交前逐项确认：
+
+- [ ] `result.json` 是 UTF-8 标准 JSON，无 `NaN`/`Infinity`
+- [ ] 顶层包含 `measurementContractVersion: "1.0"`
+- [ ] 每个正式测量项都有 `taskNo`、`metricCode`、纯 `name`、`value`、`status`
+- [ ] 多位置结果使用相同任务号并通过 `position` 区分
+- [ ] 头车/中车任务号来自 `context.inspectionObject`，没有默认猜测
+- [ ] `measurements` 中没有 `info` 状态和算法中间量
+- [ ] 单位、公差、理论值和换算口径与正式任务清单一致
+- [ ] `extra.intermediateMetrics` 中的指标不参与合格判定
+- [ ] 已执行：`python3 validate_result.py result.json`
+- [ ] 版本说明记录了输出字段变化
+
+## 12. 校验方式
+
+本目录提供两种校验：
+
+```bash
+# 零第三方依赖，执行本规范的关键业务规则校验
+python3 validate_result.py /path/to/result.json
+
+# 如本机安装了 jsonschema，可进行完整 JSON Schema 校验
+python3 -m jsonschema -i /path/to/result.json result.schema.json
+```
+
+示例自检：
+
+```bash
+python3 validate_result.py examples/head-car-coupler-and-deflection.result.json
+```

+# 算法输出规范执行通知（转发模板）
+
+各位算法同事：
+
+为统一平台“算法结果”中的任务号、测量位置、单位、公差和中间数据，从现在起请新交付算法以及存量算法的后续版本遵循：
+
+`alg/00_算法交付与输出规范/README.md`
+
+目录内同时提供：
+
+- `result.schema.json`：完整 JSON Schema；
+- `validate_result.py`：零第三方依赖校验器；
+- `examples/head-car-coupler-and-deflection.result.json`：正确示例；
+- `examples/invalid-legacy-result.json`：禁止的旧写法反例。
+
+本次最关键的变化：
+
+1. 正式测量结果必须单独返回 `taskNo`，不再把任务号写在 `name` 中；
+2. `name` 只保留纯项目名称；同一任务的左/右等多个结果使用 `position` 区分；
+3. 每个指标必须提供稳定的 `metricCode`；
+4. 头车/中车必须依据输入的检测对象选择任务号，不得默认猜测；
+5. `dx_y`、`dx_z`、拟合残差、法向量等中间量不得进入正式 `measurements`，统一放入 `extra.intermediateMetrics`；
+6. 正式结果只允许 `pass`、`warning`、`fail`，不再用 `info` 表示可交付项；
+7. 交付前请执行：
+
+```bash
+python3 alg/00_算法交付与输出规范/validate_result.py /path/to/result.json
+```
+
+请各算法负责人先检查自己的输出，并回复以下信息：
+
+- 指标与正式业务任务号的映射是否完整；
+- 哪些输出是正式测量值，哪些只是计算中间量；
+- 同一指标是否会因头车/中车等检测对象对应不同任务号；
+- 单位、公差、理论值和换算口径是否与正式任务清单一致；
+- 预计从哪个算法版本开始按新规范交付。
+
+车钩与挠度算法请重点确认：
+
+- 任务 5 的左梁、右梁作为同一任务的两个 `position` 输出；
+- 头车车钩对应任务 8、10，中车对应任务 9、12；
+- `dx_y`、`dx_z` 仅保留为中间量；
+- “右偏转角”最终交付口径是角度 `°`，还是偏差值/基准长度（例如 `0.073/700 mm`）。
+
+平台插件的运行、输入、进度和产物接入仍参考 `docs/algorithm-integration-spec.md`；测量结果字段发生冲突时，以新规范为准。
