----
-
-# 自动 commit 并 push
-
-读取当前 git 改动，生成简洁的中文 commit 信息，然后自动提交并推送。
-
-## 执行步骤
-
-### 1. 查看当前状态
-
-先了解仓库当前情况：
-
-```bash
-git status
-git diff --stat        # 看改动了哪些文件、改动量
-git diff               # 看未暂存的具体改动
-git diff --staged      # 看已暂存的具体改动
-git log --oneline -5   # 看最近几次提交风格，保持一致
-```
-
-### 2. 分析改动
-
-基于 diff 内容，理解这次改动**实际做了什么**：
-
-- 新增了什么功能/文件
-- 修改/修复了什么
-- 删除/重构了什么
-- 是文档、配置还是代码改动
-
-**不要凭文件名猜测，要看实际 diff 内容。**
-
-### 3. 生成 commit 信息
-
-要求：
-
-- **中文**，简洁，**一句话**概括这次改动的核心内容
-- **不要前缀**（不用 feat/fix/docs 这种 Conventional Commits 前缀）
-- 直接描述做了什么，动词开头，如"添加 ALNS 自适应大邻域搜索算法"、"修复 POX 交叉中的索引越界问题"、"重构 FJSP 解码逻辑去掉 AGV 部分"
-- 如果一次改动包含多个不相关的事情，提示用户是否要分开提交（但默认仍按一条处理）
-- 长度控制在一行能看完，不写冗长描述
-
-### 4. 自动提交并推送
-
-确认 commit 信息后，依次执行：
-
-```bash
-git add -A                          # 暂存所有改动
-git commit -m "生成的中文commit信息"
-git push                            # 推送到当前分支的远程
-```
-
-### 5. 处理常见情况
-
-- **没有改动**：如果 `git status` 显示没有改动，告知用户无需提交，停止
-- **push 失败**：
-  - 如果是因为远程有新提交（需要先 pull），告知用户，建议先 `git pull` 或 `git pull --rebase`，**不要自动强推**
-  - 如果是没有配置远程或没有 upstream 分支，提示用户，给出 `git push -u origin <分支名>` 的建议命令
-  - 如果是认证问题，告知用户检查凭证
-- **当前在重要分支**（如 main/master）：正常执行，但在输出里提示一下当前分支名，让用户心里有数
-
-### 6. 输出
-
-完成后简要报告：
-
-- 生成的 commit 信息
-- 提交到了哪个分支
-- push 是否成功
-
-## 注意事项
-
-- commit 信息必须如实反映 diff 内容，不编造
-- push 失败时不要用 `--force` 强推，交给用户决定
-- 如果改动很大很杂，主动提示用户考虑拆分提交，但不强制

-description: Create, update, audit, or synchronize repository README documentation from evidence in the codebase. Use when the user asks to write or improve a README, document setup/build/run/test workflows, explain project structure or architecture, fix stale README content, or maintain multilingual README files for any software project.
----
-
-# README维护
-
-生成或更新准确、简洁、可执行的项目README，不预设托管平台、技术栈、运行环境或文档语言。
-
-## 工作流程
-
-### 1. 调研仓库
-
-- 读取适用的`AGENTS.md`、现有README和主要设计文档。
-- 检查源码目录、项目清单、依赖文件、入口、配置、构建脚本、测试和CI配置。
-- 使用`rg --files`和针对性搜索；排除`bin`、`obj`、`build`、依赖缓存及其他生成目录。
-- 从代码和配置确认项目名称、用途、模块边界、环境要求及实际命令，不根据目录名猜测。
-
-### 2. 确定范围
-
-- 优先更新现有README，保留仍然准确的内容和仓库既有风格。
-- 默认沿用现有文件名和主要语言。
-- 只有用户明确要求或仓库已有约定时，才创建双语或多份README，并添加相对链接切换语言。
-- 删除或修正已改名、已删除、不存在或无法验证的内容。
-
-### 3. 组织内容
-
-根据项目实际情况选择必要章节，不强制套用完整模板。常用顺序为：
-
-1. 项目名称与一句话说明
-2. 当前能力与适用范围
-3. 目录或架构概览
-4. 环境与依赖
-5. 构建、运行和测试
-6. 配置与部署
-7. 已知限制或故障排查
-8. 贡献方式与许可证（仅在仓库有依据时）
-
-- 把最常用的成功路径放在前面。
-- 仅在能显著解释模块关系或执行流程时使用表格、目录树或Mermaid图。
-- 使用相对路径链接仓库内文件，避免复制大段源码或生成完整文件清单。
-
-### 4. 保证事实准确
-
-- 命令必须来自项目文件、脚本或已验证的工具链；不要编造安装、启动、部署或硬件步骤。
-- 区分“已验证可用”“根据配置推断”和“尚未验证”，不要把编译成功描述为运行或实机验证成功。
-- 不编造版本、性能指标、兼容平台、许可证、维护状态或安全保证。
-- 不在README中写入密码、令牌、内网地址、个人路径或其他敏感信息。
-- 信息不足时优先省略非必要章节；必要信息缺失时明确标注待确认内容。
-
-### 5. 验证结果
-
-- 检查README中的名称、路径、文件和命令仍真实存在。
-- 检查中英文或多语言版本的关键事实、命令和链接保持一致。
-- 对能够安全执行的核心命令进行适度验证；未执行时明确说明。
-- 查看最终差异，避免无关重写、重复章节和过度宣传。
-
-## 写作要求
-
-- 面向首次接触仓库的开发者，使用直接、具体、可操作的语言。
-- 说明“是什么、怎么用、如何验证”，避免空泛的优势描述。
-- 保持章节简短；复杂设计链接到专门文档，不把README写成完整设计说明书。
-- 代码块标注正确语言，命令应可复制，并注明必要的工作目录或前置条件。

+%   RESULT = PREPARE_STEERING_IDDATA() reads the two experiment folders next
+%   to this file, detects every steering target step, aligns command and
+%   feedback timestamps, resamples each response to 0.04 s, and saves:
+%
+%     dataEstLF/LR/RF/RR  uDiff -> delta actual steering angle
+%     dataValLF/LR/RF/RR  independent validation data

+%
+%   Each variable is a multi-experiment iddata object. Import one wheel at a

+%   (Kp=0.0035, dead zone=0.1 deg) is used for estimation and the third

+# Detour 定位接口信息确认（源码答复）
+
+用途：答复控制程序（`MultiWheelC` / `StateEstimation`）使用定位结果所必需的接口语义。
+依据：本仓库 `DetourCore` 源码（`Location.cs`、`TightCoupler.cs`、`Frame.cs`、`LidarOdometry.cs`、`LidarMap.cs`、`WebAPI.cs`、`G.cs`）。
+仓库内**没有**名为 `getCartLocation()` 的函数；控制侧该调用对应 Detour 的两类对外位姿出口。下文按字段对齐后统一说明。
+
+---
+
+## 对外位姿出口（先对齐接口）
+
+控制程序看到的 `x / y / theta / tick / l_step`，来自下面之一（或对它们的封装）。字段名在源码里是 `th`，不是 `theta`。
+
+| 出口 | 入口 | 字段 | `tick` 的真实来源 |
+|---|---|---|---|
+| HTTP `GET /getPos` | `CartLocation.FormatPosition()` | JSON：`x, y, th, l_step, tick`，异常时多 `error` | `tick = CartLocation.st_time`（观测时刻） |
+| 共享对象 `DetourPos{shareObjectTag}` | `TightCoupler.CommitLocation` 每次提交后 `Post` | 二进制：`x, y, th, tick, l_step, error` | `tick = DateTime.Now.Ticks`（提交/推送时刻） |

+
+## 1. `getCartLocation()` 字段定义
+
+### 1.1 各字段含义
+
+| 字段 | 源码名 | 含义 |
+|---|---|---|
+| `x` | `CartLocation.x` | 车体原点在**当前地图坐标系**中的 X。已从传感器坐标系经安装外参反变换到车体中心（`TightCoupler.CommitLocation` 里 `ReverseTransform(传感器位姿, 组件安装位姿)`）。 |
+| `y` | `CartLocation.y` | 同上，Y。 |
+| `theta` | `CartLocation.th` | 车体航向。`0°` 朝向地图 `+X`，逆时针为正（内部用 `cos(th)` / `sin(th)` 画朝向）。 |
+| `tick` | 见上表 | **不是**统一的一种时间。HTTP 是观测时间 `st_time`；DObject 是提交瞬间的 `DateTime.Now.Ticks`。控制侧必须先确认自己走的是哪条通道。 |
+| `l_step` | `Frame.l_step` | **到已标注（labeled）关键帧的图上步数**，用来表达“离可信锚点有多远”，**不是**优化迭代次数，也不是匹配分数。注释原文：`steps to labeled keyframe`。 |
+
+### 1.2 单位、正方向、坐标系
+
+- **内部单位**：`x`、`y` 为毫米。UI 直接按 `mm` 显示。
+- **对外单位**：默认仍是毫米；只有改了 `guru.inputScale`（例如设为 `1000` 输出米）才会变。
+- **角度单位**：度。
+- **坐标系**：当前加载的 SLAM 地图坐标系。原点由建图/标注关键帧决定，不是 GNSS 或车体启动点。
+- **车体姿态**：输出的是**车体原点**，不是雷达原点。雷达/相机安装位姿在 `layout.components` 的 `x,y,th` 里。
+- **右手平面**：`+X` 为航向 0，`+Y` 为航向 +90°。
+
+### 1.3 `theta` 取值范围
+
+**不是严格的 `[-180°, 180°]`。**
+
+`LessMath.normalizeTh` 只在绝对值 ≥ 360 时按 360° 回绕，`(-360, 360)` 内原样返回。因此对外可能看到 `200`、`-270` 这类值。控制程序若假设 `[-180, 180]` 或 `[0, 360)`，应自己归一化。内部比较角度用 `LessMath.thDiff`，会按最短弧处理。
+
+### 1.4 一次调用的字段是否同一帧
+
+**是。** 一次读取对应同一个 `CartLocation` 对象上的 `x/y/th/l_step/st_time`。
+`getPos` 先用当前 `latest` 判断 Timeout/Unstable，再序列化；若这两步之间恰好发生新提交，状态字和位姿可能差一帧，但单次 JSON 里的数值字段仍来自同一个对象。
+
+---
+
+## 2. `tick` 的准确含义（优先）
+
+### 2.1 它是什么时刻
+
+分通道：
+
+**HTTP `/getPos` 的 `tick` = `st_time`**
+
+- `st_time` 在 `Frame` 上的注释是：传感器数据**到达 Detour 时**由 `G.watch` 打的时间，不是激光头硬件曝光时刻，也不是 HTTP 返回时刻。
+- 激光采集线程会按扫描周期做轻微平滑，并加上 `time_bias_ms`。
+- 里程计把 `frame.st_time` 原样交给 `TightCoupler.CommitLocation`，再写入 `CartLocation.st_time`。
+- 因此：`tick` ≈ **该位姿所对应的那帧观测到达时刻**。SLAM 计算发生在这之后，接口返回更晚。
+
+**DObject `DetourPos` 的 `tick` = `DateTime.Now.Ticks`**
+
+- 这是 **TightCoupler 提交并推送的本地时刻**，100 纳秒为单位，从公元 1 年 1 月 1 日起算（.NET `DateTime.Ticks`）。
+- 它**不是**传感器采集时刻，也**不是** Unix epoch。
+- 受本机本地时钟、时区、校时影响，必要时可能回跳。
+
+### 2.2 单位、频率、单调、回绕
+
+| 项目 | HTTP `tick`（`st_time`） | DObject `tick`（`DateTime.Now.Ticks`） |
+|---|---|---|
+| 单位 | 毫秒 | 100 ns（1 ms = 10000） |
+| 时钟 | 进程启动时锚定一次 UTC，之后用 `Stopwatch` 单调累加：`ElapsedTicks*1000/Frequency + stMillis` | 本机本地 `DateTime.Now` |
+| 更新频率 | 随传感器/融合提交，通常接近雷达帧率（常见 10–20 Hz，取决于设备 `timeBudget`） | 每次 `CommitLocation` 成功推一次 |
+| 单调 | 进程内单调递增（不受事后改系统时间影响） | 一般递增；改系统时间或 DST 可能回跳 |
+| 回绕 | `long` 毫秒，实际不会回绕 | `long` ticks，实际不会回绕 |
+| 进程重启 | 重新锚定当前 UTC，**不会从 0 开始**，但与重启前不保证连续 | 继续跟本机时钟，与进程无关 |
+
+`G.watch.TimeStampMillis` **不是** Unix 毫秒（1970），而是从公元 1 年起算的 UTC 毫秒，再加上启动后的单调流逝。
+
+### 2.3 多车能否用 `tick` 对齐
+
+**不能当作已同步的多车时钟。**
+
+- 各车各自启动 `G.watch`，没有 PTP/NTP 协议，也没有跨车时间服务。
+- HTTP `tick`：若各车系统 UTC 在启动时大致同步，数值会接近“同一套绝对时间”，但仍有启动锚定误差和各车处理延迟，**不能直接当多车位姿对齐的主时钟**。
+- DObject `tick`：本地时间 ticks，跨时区会直接错开，更不适合多车对齐。
+- 进程重启、暂停（`G.paused`）、提交失败都会造成时间空洞。
+
+控制侧建议：单车内部用 `tick` 做延迟估计和短时预测；多车对齐应使用外部统一时钟，或只把 Detour `tick` 当相对时间。
+
+---
+
+## 3. 定位延迟与更新方式
+
+### 3.1 输出位姿比真实运动滞后多少
+
+源码**没有**标定“官方延迟 xx ms”。能确定的是延迟结构：
+
+```
+真实运动 → 雷达扫描/到达(st_time) → 里程计配准 → TightCoupler 融合 → 写入 CartLocation.latest → 接口读到缓存
+```
+
+经验上由源码阈值约束：
+
+- 激光一圈通常几十毫秒（`Lidar2DStat.timeBudget`）。
+- TightCoupler 常用窗口 `TCtimeWndSz = 150 ms`，上限 `TCtimeWndLimit = 700 ms`。
+- `LidarOdometry` 把 `reg_ms > 200` 记为 `bad perf`。
+- `/getPos` 若 `now - st_time > 500 ms` 打 `Timeout`。
+
+因此正常运行时，**从观测到可读位姿大约是 1 帧雷达周期 + 配准/融合，常见几十到两百毫秒；超过 500 ms 会被 HTTP 接口判超时。** 这是实现上的门槛，不是出厂标定值。
+
+### 3.2 `getCartLocation()` 是否返回最近一次缓存
+
+**是。**
+
+- `CartLocation.latest` 是全局缓存。
+- 只有 `TightCoupler.CommitLocation` 成功后才会替换（取 `history` 中 `st_time` 最新的一帧）。
+- `/getPos` 只读缓存，不触发新的 SLAM 计算。
+- 配准失败、`CommitLocation` 返回 `null`（`bad variance` / `bad trace`）、或 `G.paused` 时，缓存停在上一帧。
+
+### 3.3 原地自转时频率/延迟是否明显变化
+
+**轮询频率不变，有效更新和延迟会变差。**
+
+- 接口仍按调用方频率读同一缓存。
+- 原地旋转时二维扫描重叠变差，帧间分、相位锁分容易掉，`allowCommit` 更常失败，缓存更容易停住。
+- 配准变慢时单帧 `reg_ms` 上升；失败后 `l_step` 被加大（见第 4 节），看起来像“转的时候定位变钝”。
+- 源码没有“自转专用降频”。
+
+控制侧：自转短时预测应假设**有效位姿更新可能变稀、变老**，不要假设 `tick` 仍按雷达周期前进。
+
+---
+
+## 4. `l_step` 的含义（优先）
+
+### 4.1 它是什么
+
+**定位质量的图距离，不是优化迭代次数，也不是匹配状态枚举。**
+
+定义：当前位姿/关键帧沿约束图走到**已标注关键帧**还要几步。
+
+- `0`：本身就是标注帧（`labeledXY` / `labeledTh`），或刚被标成锚点。
+- `1`：刚和地图/标注帧配准成功（`LidarMap` 成功后会把 `compared.l_step = 1`）。
+- 正常递推：新关键帧 `l_step = 旧关键帧.l_step + lstepInc`。
+- TightCoupler 提交时：有参考关键帧则 `reference.l_step + 1`；没有则 `latest.l_step + 3`。
+- `9999`：未定位、手动设位、或与标注图断开。这是 `Frame` / 初始 `CartLocation` 的默认值。
+
+**越小越好、越可信。**
+`AIImplementationNote.md` 里“越小越不确定”与源码相反，不要采用。
+
+内部用途包括：
+
+- TightCoupler 边权：`l_step > 10 → 1`，`> 5 → 2`，`> 2 → 3`，否则 `4`；标注帧权 1000。
+- 图优化用 `1/(l_step+0.01)` 当权。
+- `l_step` 大时 `LidarMap` 更容易走全局配准（`forceGRegStep`、`GregThresK * l_step`）。
+- `l_step > 1000` 且孤立的关键帧可被删掉。
+
+源码 TODO 也写过：希望将来“去掉 `l_step`，改用误差圆”。当前对外接口仍是这个整数。
+
+### 4.2 为什么原地自转会从 2～4 升到几十、上百
+
+自转本身不会改公式，但会让 **`lstepInc` 连续被惩罚**，再在切关键帧时一次性加到 `l_step` 上。
+
+`LidarOdometry` 里常见加项：
+
+| 条件 | `lstepInc` 增量 |
+|---|---|
+| 帧间隔过大 | `+3`～`+20` |
+| 时间落后 > 1 s | 可到 `+1000` 量级并重启局部图 |
+| 有效点太少 | `+3` |
+| 掩膜后点过少 | `+10` |
+| 帧间序贯配准失败 | `+5` |
+| 局部里程计分过低 | `+15` |
+| 历史分偏低 | `+1`～`+15` |
+| 局部图重启 / 相位锁差 | `+2` |
+| 上一帧能提交、这一帧不能 | `+100` |
+| 离开 hard 区域 | 默认再 `+20` |
+
+原地自转时典型连锁是：旋转导致重叠变差 → 分数掉 → `lstepInc` 累加 → 因“新点变多 / 超时 / restart”切关键帧 → `新 l_step = 旧值 + lstepInc`。
+若此时地图匹配也失败，TightCoupler 按 `latest.l_step + 3` 继续推高。
+所以 2～4 很快可以变成几十，失败恢复前看到上百是符合实现的。
+
+匹配一旦重新成功，关键帧会被改回 `l_step = 1`，输出也会掉下来。
+
+### 4.3 有没有官方阈值
+
+**没有写给控制程序的官方阈值表。** 下面是源码内部实际在用的分档，可作控制侧初值，现场仍要按地图和雷达标定。
+
+| `l_step` | 源码含义 | 给控制程序的建议 |
+|---|---|---|
+| `0` | 标注锚点 | 最可信 |
+| `1`～`2` | 刚贴上地图 / 离锚点很近 | **正常，接受** |
+| `3`～`5` | TightCoupler 已降权 | 可用，开始警惕跳变 |
+| `6`～`10` | 权更低；地图更倾向全局配准 | **退化，降低信任 / 收紧预测** |
+| `11`～`98` | 最低权；曾从不稳定区回到 `2` 时会打工作区快照 | **明显退化，不宜做精细控制** |
+| `≥ 99` | TightCoupler 允许关键帧被推得更狠 | 按不可靠处理 |
+| `≥ 1000` | 孤立帧可删 | 基本断开 |
+| `9999` | 未定位 / 手动设位 / 断开 | **不可用，应安全停止或等待重定位** |
+
+Detour 自己判断“车是否静止可做全局重定位”时用：`l_step > 2` 且 TightCoupler 速度估计很小。这是内部策略，不是对外状态机。
+
+---
+
+## 5. 坐标跳变与重定位行为（优先）
+
+### 5.1 重定位、回环、失败恢复后，`x/y/theta` 会不会永久跳变
+
+**会。跳变是设计行为，不是毛刺。**
+
+会改当前输出的情况：
+
+1. **地图配准成功**：`LidarMap` 把当前关键帧改到匹配位姿，并 `l_step = 1`，再交给 TightCoupler。下一帧 `CartLocation` 跟着新参考走，表现为一次台阶。
+2. **全局重定位**（`/relocalize` 或 UI Relocalize）：定位器进入 `relocalizing`，按全图关键帧搜索（`source = 9`）。第一次更好的匹配会 `TightCoupler.Reset`，位姿被拉到地图上，通常是大幅度永久跳变。
+3. **回环 + `GraphOptimizer`**：关键帧 `x/y/th` 被就地改写。当前参考帧若被挪动，后续融合位姿跟着变。优化有动量平滑，但仍可能出现肉眼可见的台阶。
+4. **手动 `/setLocation`**：直接改 `CartLocation.latest` 并重置融合窗口。
+5. **匹配长期失败后突然恢复**：从里程计漂过的位置一下子贴回地图，跳变幅度等于累计漂移。
+
+没有“只在内部跳、对外插值抹平”的保证。控制程序必须自己做跳变连续化或拒绝。
+
+### 5.2 跳变后还在原来的地图坐标系吗
+
+**同一张已加载地图内：是。**
+跳的是车在这张图里的估计，不是换了一套轴。
+
+会换坐标系的只有：换图（`/loadMap`）、`Remapper`（GNSS/外参映射）、或手动把车标到另一个锚点。这些不是普通重定位。
+
+### 5.3 有没有“正在重定位 / 定位丢失 / 地图坐标调整”标志
+
+**定位结果包里没有这些标志。**
+
+内部有、但**不随 `getPos` / `DetourPos` 下发**：
+
+| 内部量 | 作用 | 是否对外 |
+|---|---|---|
+| `Locator.relocalizing` / `relocalized` | 地图层正在/已经全局搜 | 否 |
+| `G.IsSettingPosition` | 正在手动设位 | 否（`/getStat` 的 `globalStat` 里能看到） |
+| `G.paused` | 定位暂停 | 否（同上，或调 `/pause` `/resume`） |
+| `CartLocation.unstable` | 本帧掩膜过狠、场景不稳定 | **仅 HTTP**：`error = "Unstable"`。DObject 当前推送的 `error` 被写成空串 |
+| `l_step` 升到很大 / `9999` | 实际的“丢了” | 是，但这是间接指标 |
+| 图优化改关键帧 | “地图坐标调整” | 无单独标志 |
+
+HTTP `/getPos` 仅有的显式错误：
+
+- `"Timeout"`：`st_time` 已超过 500 ms
+- `"Unstable"`：`latest.unstable == true`
+
+没有 `"Relocalizing"`、`"Lost"`、`"MapAdjusted"`。
+`/getStat` 可拉到各模块 `StatusMember`（雷达间隔、里程计状态、TC 状态等），但不是每帧位姿附属字段，也不适合当硬实时互锁。
+
+控制侧应自己构造状态：
+
+- **疑似丢失**：`error` 为 Timeout/Unstable，或 `l_step ≥ 99`，或 `tick` 长期不涨。
+- **疑似重定位/回环跳变**：相邻两帧 `x/y/th` 突变，同时 `l_step` 突然掉回 1～2。
+- **地图在拧**：跳变较缓、持续多帧，且 `l_step` 并不爆掉。
+
+---
+
+## 6. 可用的定位质量接口（优先）
+
+### 6.1 除 `l_step` 外还能拿到什么
+
+**位姿包几乎只有 `l_step` + HTTP 的 `error`。**
+
+| 信息 | 有没有 | 说明 |
+|---|---|---|
+| 匹配得分 | 对控制程序：无 | 在 `LidarOdometry` / `LidarMap` 内部（`score`、`phaselocker_score`），不下发 |
+| 协方差 | 对控制程序：无 | `Frame.errXX/errXY/errYY` 已预留，**未填进 `/getPos` 或 `DetourLocation`** |
+| 置信度 | 间接 | 就是 `l_step`；源码 TODO 想换成误差圆，尚未做 |
+| 定位状态 | 很弱 | HTTP：`Timeout` / `Unstable`；DObject：`error` 目前恒为空 |
+| 错误码 | 无枚举 | 只有上述字符串 |
+| 系统状态 | 有，但是慢接口 | `GET /getStat` → 布局/里程计/定位器/TC/GO/`G.paused`/`G.IsSettingPosition` |
+
+因此控制程序**不能**指望每帧拿到匹配分或协方差。
+
+### 6.2 Detour 实际用什么条件接受一帧（可当作官方内部规则）
+
+源码里“接受并提交”的条件是分层的，没有单独的对外规范文档：
+
+1. **里程计层**（`LidarOdometry.updateLocation`）
+   - 分数过低会把 `strength` 压下去，甚至不把 `reference` 挂上。
+   - 掩膜过狠 → `unstable = true`。
+   - 点太少、序贯/局部配准失败 → 不切健康关键帧，并加大 `lstepInc`。
+2. **融合层**（`TightCoupler.CommitLocation`）
+   - 传感器处于 `bad variance` / `bad trace` → 直接丢弃，返回 `null`。
+   - 丢弃后该源会被禁一段时间（约 1～2 s）。
+3. **地图层**（`LidarMap`）
+   - `result.score < ScoreThres` 丢弃。
+   - 相对已有位姿的 `xy/th` 偏差超过按 `l_step` 放大的门限则丢弃（防止乱跳）。
+   - 落到无效区域丢弃。
+4. **HTTP 出口**
+   - 缓存超过 500 ms → `Timeout`。
+   - `unstable` → `Unstable`。
+
+### 6.3 建议控制程序如何接受/拒绝一帧
+
+源码没有写给 `MultiWheelC` 的官方判据。按上面的内部规则，建议：
+
+**接受（正常闭环）**
+
+- HTTP：无 `error`（DObject：至少 `tick` 在前进）。
+- `l_step ≤ 5`。
+- `tick` 新鲜（HTTP：`now - tick < 300 ms` 较稳妥；DObject：换算成 ms 后同样看提交间隔）。
+- 相对上一接受帧：位移/转角不超过本底盘短周期能达到的上限。
+
+**降级（短时预测、降低增益、禁止精细对位）**
+
+- `6 ≤ l_step ≤ 10`，或偶发 Timeout 后立刻恢复。
+- 原地自转期间 `l_step` 爬升但 `tick` 仍在更新。
+
+**拒绝并安全停止 / 等待**
+
+- `error == "Timeout"` 持续，或 `error == "Unstable"`。
+- `l_step ≥ 99`（含 `9999`）。
+- 单帧出现与运动学不符的永久台阶（尤其伴随 `l_step` 从很大突然回到 1）：先当重定位跳变，做连续化或刹停，不要直接当编码器。
+
+**不要做的事**
+
+- 不要用 `l_step` 当 ICP 迭代次数或“正在计算中”。
+- 不要假设 `theta ∈ [-180, 180]`。
+- 不要用 `tick` 做多车时间同步主时钟。
+- 不要假设 DObject 的 `error` 会带 Timeout/Unstable（当前实现是空的）。
+
+---
+
+## 对 `StateEstimation` 的直接含义
+
+清单里最优先的 2 / 4 / 5 / 6，对应控制侧应这样定：
+
+1. **时间同步**
+   - 先确认 `getCartLocation` 走 HTTP 还是 `DetourPos`。两条通道的 `tick` **单位和语义都不同**。
+   - 单车：用 `tick` 估延迟、做自转短时预测。
+   - 多车：另选同步时钟。
+
+2. **自转短时预测**
+   - 自转时有效更新可能变稀，`l_step` 会从个位数爬到几十上百。
+   - 这是质量变差，不是接口卡死。预测窗口应随 `tick` 变老、`l_step` 变大而缩短。
+
+3. **跳变连续化**
+   - 重定位、回环、失败恢复都会造成**同地图下的永久台阶**。
+   - 没有“正在改图”标志；用位姿差分 + `l_step` 回落来识别。
+
+4. **安全停止**
+   - 硬条件：`Timeout` / `Unstable` / `l_step ≥ 99` / `tick` 停更。
+   - `l_step` 建议按 `≤5` 正常、`6–10` 退化、`>10` 不可用于精细控制。

+## 入口与宿主生命周期
+
+### C层
+
+- `PilotDefinition : MultiWheelPilotDefinition<PilotConfig, PilotDefinition>` 是Clumsy车型定义和M/C IO边界。
+- `PilotDefinition.Conf` 是动作读取运行配置的统一入口；`PilotConfig` 字段提供元数据和默认值。
+- `[MovementTest]` 类型由宿主发现并执行，例如 `NewControllerStraight4mTest`、`NewControllerReverseStraight4mTest`、`NewControllerCrab45Straight4mTest`、`TestRotateAngle` 和 `CompositeStopTurnGoTest`。
+- `MovementDefinition.Get()` 以 `IEnumerable<bool>` 形式协作执行：`true` 表示继续，结束动作时返回/产生 `false` 或退出枚举。具体宿主调度细节来自外部程序集，仓库内不可完全确认。
+
+### M层
+
+- `DiverCartDefinition : MultiWheelCartDefinition` 是Medulla车型定义。
+- `CommunicationInit()` 打开并配置MCU桥。
+- `[UseLadderLogic]` 注册 `AlarmRoutine`（50ms）、`MotorRoutine`（50ms）和 `MCURoutine`（20ms）；这些是声明的扫描间隔，不能直接等同于实测稳定周期。
+- `[UseManualController]` 注册 `Remote`。

+
+`TrajectoryTrackingMovement` 默认从 `PilotDefinition.Conf` 读取车辆级参数，同时保留少量动作级覆盖字段；横向控制器可通过 `LateralControllerFactory` 替换，纵向控制器当前固定创建为 `PidLongitudinalController`。

+
+`FleetLayoutCapture` 只负责固定布局的几何计算：车队原点X/Y取成员车体中心的算术平均，车队Yaw取主车Yaw，再把各成员世界位姿反变换为 `VehicleLayout.PoseInFleet`。它不读取通信或Detour，也不负责静止/夹紧确认、时间对齐和布局激活。
+
+`Shared/Fleet/FleetProtocol.cs` 已定义最小任务命令和成员报告值类型，`IFleetTransport` 已把运行逻辑与无线串口或内存队列隔离；测试项目中的 `InMemoryFleetTransport` 只用于无通信硬件验证，不进入正式部署。`FleetSafetySupervisor` 在主车侧按成员报告接收时间、状态和故障锁存整队停车决定，`FleetMemberAgent.UpdateCommandWatchdog()` 在每辆车本地按命令有效期独立停车，避免通信中断时只依赖主车广播停止。
+
+`MultiWheelC/Fleet/FleetRuntime.cs` 已贯通首版固定布局滚动任务：同一类型按 `selfVehicleId`/`leaderVehicleId` 区分角色；主车执行β准备、全员Ready、统一激活、状态缓存、安全判定、周期协调、本车直接执行和远端分发；从车执行任务/序列校验、舵轮准备、激活、速度命令、本地看门狗和状态上报。完成、通信/状态/成员故障和取消都会由运行层转换为本车停车及可达成员停止命令，失联成员最终由本地命令有效期兜底。
+
+当前端到端链路只通过测试项目的内存传输验证，尚未接入C层正式 `Movement/Experiment`、实际成员状态采集、无线串口和真实跨机时间换算。实际部署仍是每车独立电脑；主车也是普通成员，其本车命令不经传输层回环。无线实现不能改变已经定义的任务号、序列号、命令有效期和本地失联停车语义。

+
+## 运动坐标系与四轮解算数据流
+
+`MultiWheelChassisAdapter` 对外只接收真实车体系 `Twist2D`。滚动动作开始前先固定运动方向β：
+
+1. `ActivateMotionFrame(β)` 调用 `MultiWheelChassis.SetOriginBias(0,0,-β)`。
+2. 车体线速度通过 `R(-β)` 表达到运动坐标系。
+3. 运动系中以 `±ControlPointRadius` 作为虚拟前后GCP，计算GCP方向。
+4. `MultiWheelChassis.SendMotion` 由两个GCP方向求瞬时旋转中心ICR。
+5. 每个真实轮子的 `PhysicalPosition` 被旋转成运动系 `Position`，再由ICR分别求切线角和速度半径比例。
+6. `sTh - sw.ZeroDirection` 把运动系方向转成真实舵轮机械命令；距离和速度大小不因坐标旋转改变。
+
+关键位置：`Shared/Chassis/MultiWheelChassisAdapter.cs`、`MultiWheelChassis.cs::SetOriginBias`、`SendMotion`、`CalculateAxes`。
+
+## 动作组织
+
+- `PrepareWheelsForward`：停车、下发任意固定方向β并等待稳定；名称保留“Forward”，但功能已支持非零方向。
+- `TrajectoryTrackingMovement`：准备运动系、创建控制器、周期执行、失败停车，可选完成后回正。
+- `MultiWheelRotateInPlace`：准备自转舵角、交接到XYTh解算、世界航向PID、完成后回正。
+- `MotionPlanExecutor`：开始运动前预检全部段，顺序执行 `TrackMotionPlanSegment` 和 `RotateInPlaceMotionPlanSegment`，共享状态源。
+
+## 构建与打包

+`build-and-package.ps1` 顺序构建 `CommonUsage`、M层和C层，将新 `CommonUsage.dll` 复制到 `ref/`，最后生成 `output/M` 和 `output/C`。两个部署包必须使用同一份 `CommonUsage.dll`。构建产物目录不作为知识来源，也不直接编辑。

+# 技术决策
+
+只记录长期有效的方案状态；实验临时参数和失败尝试不在此保存。
+
+## 已经实施
+
+### 1. 分离 CommonUsage、Shared、M层和C层
+
+- `CommonUsage` 保持独立通用底盘库，不反向依赖项目控制层。
+- `Shared` 只保存M/C共享模型、数学、校验和底盘适配，不建立独立程序集。
+- `MedullaAdapter` 管硬件，`MultiWheelC` 管动作和控制。
+- 原因：避免硬件通信、控制算法和旧底盘库相互反向耦合。
+- 依据：三个 `.csproj`、`AGENTS.md`。
+
+### 2. Shared统一SI单位和真实车体系命令
+
+- Shared使用m、m/s、rad、rad/s，车体系X前Y左、逆时针为正。
+- 对外底盘命令统一为 `Twist2D`；旧版mm/deg接口只在 `MultiWheelChassisAdapter` 边界转换。
+- 原因：减少不同层之间的单位和符号歧义，为后续单车/车队刚体速度分配保留统一模型。
+
+### 3. 显式β运动坐标系，不根据速度分量猜测模式
+
+- 切换流程固定为停车、预对齐舵轮、`ActivateMotionFrame(β)`，运行阶段统一调用 `SendBodyTwist()`。
+- β=0表示车头方向，β=90°表示车体左侧作为虚拟前向；支持任意固定β。
+- 实际四轮始终使用真实布局参与解算，β只改变表达坐标系。
+- β不是改变目标刚体运动的额外自由度；它用于为同一 `BodyTwist` 选择本运动段更易满足舵角、最小转舵和非奇异条件的主要滚动方向。
+- β不增加车辆物理运动能力，也不改变同一刚体速度最终要求的轮子滚动轴线；当前主要价值是让真实车体系 `BodyTwist` 能稳定接入方向型旧 `SendMotion`，并使虚拟GCP角远离±90°表达奇异区。若以后改为 `BodyTwist` 直接到四轮的完整逆解，β可以退化为底盘内部的等效解选择，不应成为车队控制器的核心概念。
+- β可参与运动前的候选方向规划，但不能代替真实舵轮限位检查：±120°保护必须对完整四轮解算结果逐轮检查，并同时考虑“舵角±180°、轮速反向”的等效解。
+- 限制：运动中不切换β；纯自转要求回到真实车体系并采用专用舵轮准备。
+- 依据：`PrepareWheelsForward`、`TrajectoryTrackingMovement`、`MultiWheelChassisAdapter`。
+
+### 4. 保留前后GCP作为旧底盘几何边界
+
+- 控制层输出前后虚拟GCP方向；`MultiWheelChassis.SendMotion` 由两条法线求ICR，再计算每个真实轮子的切线方向和速度比例。
+- GCP是刚体控制点，不是物理轮轴中心；`ControlPointRadius` 必须在前馈、运动学和旧解算中保持一致。
+- 原因：复用已经存在的机械限位、等效舵角、速度斜坡和差速舵轮分配逻辑。
+
+### 5. 轨迹采用弧长参数化而非时间参数化
+
+- 轨迹保存点序、累计弧长、车体中心位姿、曲率和有符号参考速度。
+- 实际周期 `deltaTime` 只进入控制器、滤波器和命令变化率，不作为轨迹索引。
+- 原因：执行进度由车辆空间位置决定，调度周期波动不会直接跳过时间采样点。
+
+### 6. 正负参考速度表达前进和倒车
+
+- 轨迹Yaw始终是车头方向；正速度前进、负速度倒车。
+- Stanley曲率前馈、横向/航向修正和终点行驶方向显式考虑速度符号。
+- 同一测试曲线要求速度同号，不在滚动中直接切换前进/倒车。
+- 依据：`TrajectoryPoint`、`TestTrajectoryFactory`、`StanleyLateralController`。
+
+### 7. 默认状态采用Detour位姿与轮组平面速度组合
+
+- 位姿来自经过校验和任务坐标连续化处理的Detour。
+- 车体系 `Vx/Vy/Vw` 来自 `GetCarSpeed(true)`，使用同一时间常数低通滤波；轮组估计有效后，控制状态的 `Omega` 也使用轮组 `Vw`。首帧尚未建立采样时间基准时速度状态无效并对外置零。
+- 轮组 `Vw` 同时用于Detour跳变期间的短时位姿预测、运动合理性和动态航向创新阈值。
+- 原因：位置仍依赖SLAM，控制速度优先使用响应更直接且不受Detour自转退化影响的电机/舵角反馈。
+- 依据：`ParkingVehicleStateProviderFactory`、`WheelFeedbackVehicleStateProvider`。
+
+### 8. 横向控制可替换，纵向控制暂保持PID
+
+- `ILateralController` 是Stanley/LQR/MPC等的稳定扩展点；`TrajectoryTrackingMovement.LateralControllerFactory` 可注入实现。
+- 默认横向为Stanley，默认纵向为 `PidLongitudinalController`。
+- 当前没有单独的控制器工厂文件，避免为手动替换增加不必要结构。
+
+### 9. 低速和终点采用单向收敛
+
+- 起步区域使用小幅释放速度；终点前读取更低速度并进入单向低速逼近。
+- 到达或越过终点后只停车，不生成反向修正速度。
+- 完成同时检查剩余弧长、终点欧氏距离、车头航向和β方向实际速度。
+- 原因：停车机器人终点附近反复前后修正风险高，优先保证运动方向稳定和可预测。
+- 依据：`ParkingGeometricController.ResolveTerminalApproachSpeed()`、`HasReachedEnd()`。
+
+### 10. 对已观察的舵轮响应加入有限前馈与预瞄
+
+- M层差速转舵已实施四轮独立的到位迟滞与模型逆前馈：默认回退参数为公共纯P `Kp=0.0042`，到位逻辑为0.5°停止区、0.8°重启区、连续3周期确认；对象逆前馈按 `targetRate/687.06` 计算并经0.15s一阶滤波，独立限幅0.03m/s。两项功能各有默认关闭的独立开关，实车参考配置可显式启用；状态不在四轮之间共享。实现位于 `DiverCartDefinition`、`MotorRoutine.CalculateDiffSteerRateFeedforward()` 和 `UpdateDiffSteerSettlingState()`。
+- 旧 `DiffSteerRateFeedforwardGain` 不再作为模型逆前馈的物理参数；PID反馈与前馈分别限幅后相加，合成差速不再受PID的±0.3m/s阈值二次截断，最终八电机仍由M层既有发送阈值独立保护。
+- Stanley曲率前馈预瞄已接入，当前车辆默认时间0.15s、最大距离0.12m。
+- 两者均是可配置补偿，不替代底层PID、真实周期和机械响应验证。
+
+### 11. 车辆级参数集中到 PilotConfig，动作只做必要覆盖
+
+- 停车控制参数集中在 `Configuration/PilotConfig.ParkingControl.cs`，动作默认读取 `PilotDefinition.Conf`。
+- 组合运动段可以覆盖自身完成条件；实验轨迹速度描述实验本身，车辆级最大命令速度仍负责最终限制。
+
+### 12. Detour阶跃采用任务坐标连续化与安全停车分级处理
+
+- Detour原始世界观测与当前任务控制位姿通过 `controlFromDetour` 隔离；疑似阶跃先进入候选确认，确认期间使用轮组 `Vx/Vy/Vw` 短时预测。
+- 仅对幅值受限且连续确认的小坐标偏移自动更新变换；大幅、不一致或超过确认窗口的变化使状态不可用，由动作安全停车。
+- 完整轨迹状态继续要求位置和航向均可靠；原地自转只依赖独立验证的航向，位置单独异常不再终止正在进行的自转，航向异常仍触发安全停止。
+- 近似原地自转期间禁止自动吸收坐标偏移，避免把旋转定位劣化写入任务坐标系；目标航向到达并停止驱动后，才在既有幅值和确认窗口内处理位置恢复，未恢复时禁止进入下一运动段。
+- `l_step` 当前只作为诊断和后续健康分级依据，不单独决定状态有效性。
+- 依据：`DetourVehicleStateProvider`、`WheelFeedbackVehicleStateProvider`、`MultiWheelRotateInPlace`。
+
+### 13. 车队布局与状态采用不可变快照，刚体速度采用确定性分解
+
+- `Shared/Fleet/FleetLayout.cs` 保存经车号唯一性和有限值校验的 `VehicleLayout` 快照，不提供搬运过程中的逐车修改入口。
+- `FleetKinematics.Decompose()` 已按平面刚体关系把 `FleetMotionCommand` 分解为各成员中心速度，并转换到各车真实车体系；不依赖通信、Detour、β、底盘限幅或QP。
+- `MultiWheelC.Tests/FleetKinematicsTests.cs` 已覆盖整体平移、绕车队中心旋转、绕成员车旋转和停止四个数学场景。
+- `MultiWheelC/Fleet/FleetState.cs` 保存车队虚拟中心的世界位姿、同一点的世界系/车队系速度、状态采样时间和速度有效性；`FleetPoseInWorld.Yaw` 定义车队 `+X` 方向，两份速度只是同一物理速度的不同坐标表达。
+- `FleetState.SampleTimestampSeconds` 采用主车/协调器生成聚合快照时的本机单调时间。成员本机时钟和Detour `tick` 的同步属于未来接收/状态估计层职责，不阻塞使用人工构造 `FleetState` 开发纯车队控制器。
+- 当前无法直接获得被搬运车辆中心，因此 `FleetLayoutCapture.Capture()` 已确定用成员车体中心X/Y的算术平均定义车队原点，用指定主车Yaw定义车队朝向；主车缺失时拒绝采集，不做隐式降级。
+- 布局采集只返回采集时刻的 `FleetPoseInWorld` 与不可变 `FleetLayout`，不读取Detour/通信，也不负责夹紧、静止、时间对齐或原子激活。6个布局采集数学场景已通过。
+
+### 14. 原地自转保留绝对航向与轮组相对角两种反馈模式
+
+- `DetourAbsoluteHeading` 保留世界航向闭环和停车后的Detour位姿恢复，适用于必须对准绝对方向的任务。
+- `RelativeWheelOdometry` 通过 `TryGetWheelTwist()` 获取与Detour无关的滤波轮组 `Vw`，按轮组采样时间积分相对角度；活动自转不因Detour位置或航向退化中断。
+- 轮组相对模式是工程降级/测试模式，不等同于绝对定位：允许约±5°误差，不能消除轮胎打滑、轮径误差和积分漂移，也不能用于长期世界航向基准。
+- 依据：`WheelFeedbackVehicleStateProvider`、`MultiWheelRotateInPlace`、`RotationTests`。
+
+### 15. 单车与车队轨迹跟踪通过组合共享纯控制核心
+
+- `PathTrackingContext` 只携带受控刚体的车体系速度、速度有效性、轨迹投影和周期控制量，不依赖 `VehicleState` 或 `FleetState`。
+- `PathTrackingCore` 集中实现投影连续性、保护/终点策略、曲率预瞄、横纵向控制和GCP分配；`ParkingGeometricController` 与 `FleetController` 分别组合该核心，负责各自的状态适配和输出边界，不通过继承复制控制流程。
+- `FleetController` 第一版只闭环车队虚拟中心，并支持固定 `β_fleet`：实际纵向速度沿β投影，GCP结果从运动坐标系旋转到车队坐标系后形成车队原点处的 `FleetMotionCommand`；成员速度继续由 `FleetKinematics.Decompose()` 确定性分解。
+- `FleetStateEstimator` 已根据固定 `FleetLayout` 和时间对齐目标时刻反算、融合车队中心，并输出每车 `FleetMemberLayoutError`；当前第一版先做候选中心两两一致性检查，再对X/Y等权平均、对Yaw做圆周平均。正负候选偏差的公共分量进入车队中心，相对分量仍保留在成员布局误差中，不会因平均而消失。成员样本的实际采集和跨电脑时间处理仍属于外层接收链。
+- `FleetCoordinator` 已串联状态估计、虚拟中心控制、布局误差警告区间内的统一速度缩放、刚体分解和 `FleetMemberCommandCorrector` 小范围纠偏；`FleetRuntime` 已把周期结果转换为本车直接执行和远端成员命令。
+- `FleetPreparationCoordinator` 已按 `beta_i = beta_fleet - theta_i` 生成成员准备目标，并通过任务号和全员Ready形成统一激活屏障；`FleetMemberAgent` 负责本车舵轮准备、激活、命令校验和底盘执行；`FleetRuntime` 将二者接入同一固定布局滚动任务生命周期。
+- 控制算法的可替换性继续由 `ILateralController`、`ILongitudinalController` 组合注入；状态源、通信、底盘发送和成员协调不进入纯核心。
+- `MultiWheelC.Tests` 已覆盖8个Stanley前进/倒车符号场景、8个车队控制周期场景、6个布局采集场景和4个刚体分解场景；统一构建与打包通过。
+
+### 16. 车队通信保持最小值契约，失联停车采用主车与本车双层保护
+
+- `Shared/Fleet/FleetProtocol.cs` 只保存 `FleetCommand`、`FleetMemberReport`、枚举和协议常量，不绑定停车机器人控制器、串口实现或复杂消息类层次；无线字节帧和校验留在具体传输实现。
+- `IFleetTransport` 是运行层唯一传输边界；当前 `InMemoryFleetTransport` 只在测试项目中模拟定向命令、广播和成员报告，后续无线实现替换该接口而不改车队算法。
+- 主车 `FleetSafetySupervisor` 依据主车本地接收时间、成员状态和故障锁存整队停车决定；每辆车的 `FleetMemberAgent` 依据本机单调时间和命令有效期独立看门狗停车。`FleetRuntime` 已执行本车停止并向可达成员下发停止，两层保护仍不能互相替代。
+- 同一 `FleetRuntime` 部署到所有车辆，角色由显式 `selfVehicleId` 与 `leaderVehicleId` 决定，不把固定车号硬编码为主车；主车也是成员，本车命令直接执行，不要求传输层回环。
+
+### 17. 纵向辨识区分目标命令、实际发送命令和停车语义
+
+- C层 `LongitudinalIdentificationTests.cs` 提供“速度阶跃与立即停车”和“速度阶跃与正常减速”两个入口，共用舵轮回正、定时命令、CSV记录、停止响应和异常停车流程，不经过Stanley或纵向PID。
+- 初次辨识保持生产配置中的 `AccPerSecond/DeAccPerSecond` 固定；上层目标速度只作为参考，车辆对象辨识以M层最终 `SentSpeed*` 为输入、轮组反馈合成速度为输出，避免把已知速度斜坡误认为车辆本体迟滞。
+- `SendBodyTwist(Twist2D.Zero)` 表示立即停车并绕过 `DeAccPerSecond`；正常减速实验必须持续发送零目标 `SendMotion`，让底盘内部发送速度按 `DeAccPerSecond` 逐周期下降。两类数据不能混为同一种制动响应。
+- 第一轮先完成当前配置的正向重复实验，再依据数据决定是否补充倒车和加减速度参数A/B；辨识过程中不同时改变多个限幅或控制参数。
+
+## 已经确认但尚未实施
+
+- 路线顺序：先完成单车闭环和停车功能验证，再正式实施多车通信、编队和协同控制。来源：`README.md`。
+- 转舵系统辨识应对四个轮组分别使用相同激励，输入采用实际差速转舵命令（`TotalDiff`或左右轮实际发送命令之差），输出采用实际舵角；若只用目标角到实际角，会把当前PID包含在闭环模型中，更换PID后该模型不能继续代表转舵机构。当前主辨识流程固定用第一次实验作估计集、第三次实验作验证集，两者角度死区均为0.1°；第二次0.5°死区实验不进入主辨识，只保留作死区敏感性参考。控制阶段优先保留四个独立PID实例和内部状态、共用一套参数，并依据四个健康轮组中最不利的动态设计稳定裕量；只有硬件健康且公共参数仍无法兼顾时，才评估配置化的逐轮小幅校准，不在代码中硬编码某个轮位特例。当前15°/s参数由 `ParkingMaximumGcpAngleRateDegreesPerSecond` 配置并在 `GcpCommandExecutor` 中限制前后虚拟GCP目标，位于上述辨识对象上游，不进入“实际差速命令→实际舵角”模型；实施顺序确定为四轮对象辨识、公共反馈/前馈设计、舵角阶跃与斜坡验证、按最慢健康轮组留裕量设置GCP变化率，最后再用轨迹实验整定曲率预瞄和横向控制参数，不删除GCP变化率保护。
+- 当前多车的固定布局滚动任务已形成内存通信可运行链路。仍缺少C层正式动作入口、布局原子激活、成员状态实际采集、跨机时间换算、公共世界坐标验证和无线传输实现。
+- 单车 `MultiWheelC/StateEstimation` 继续负责Detour重复帧、跳变候选、轮速短时预测和任务坐标连续化；车队层不复制这套原始定位处理，只消费经过本车校验的成员状态，并负责跨车时间对齐、固定布局反算、成员一致性检查和中心融合。成员状态进入融合前仍必须确认处于同一公共坐标系；各车独立的 `_controlFromDetour` 连续化变换是否会造成跨车基准差异，属于通信/状态接收契约必须验证的事项。
+- 第一版保留当前保守的等权车队中心融合；任务生命周期和内存零速运行链已经贯通。公共坐标系与主车时间轴语义确认并取得静止/低速双车日志后，再按数据增加车队历史预测、逐成员创新门控、健康降级和Huber等鲁棒加权；不在缺少Detour协方差时提前实现协方差加权或Covariance Intersection。
+- 布局生命周期区分夹紧前后的语义：夹紧前的预设布局只用于引导车辆就位；车辆夹紧且静止后，应同步取得同一世界坐标系下的成员位姿，调用 `FleetLayoutCapture` 创建新的不可变布局，再由上层协调器原子激活。共同搬运期间的相对位姿变化属于状态误差，不能通过修改 `FleetLayout` 吸收；松开车辆后清除激活布局。实际数据采集和激活接口尚未实施。
+- 多车共同搬运不能只闭环车队中心：整体位姿误差与成员相对布局误差必须分开估计和约束，否则成员误差可能相互抵消而使平均中心看似正确。
+- 计划采用分层职责：车队控制器产生参考点 `FleetTwist`，分配层依据成员 `VehicleLayout` 计算每车真实车体系 `BodyTwist`，单车层继续负责β变换、GCP和本车四轮解算。
+- 第一版采用确定性的虚拟刚体速度分配，不先引入QP/HQP：若成员在车队系中的固定布局为位置 `(x_i,y_i)`、朝向 `theta_i`，则成员中心在车队系中的速度为 `(Vx-omega*y_i, Vy+omega*x_i, omega)`，再通过 `R(-theta_i)` 转到本车体系后交给 `SendBodyTwist()`。QP/HQP只在需要同时调整车队参考速度、处理成员能力差异、松弛约束或严格任务优先级时再引入。
+- “按状态最差车辆协调速度”第一步已经对成员相对布局误差实现警告阈值至停止阈值之间的统一速度缩放。通信超时、状态不可用、成员故障和命令有效期已经进入运行链；成员报警/夹紧信号来源、可恢复降级策略和实车阈值仍待接入，延迟预测补偿可以后续增加。
+- 虚拟车队使用固定在车队坐标系中的对称前后GCP，把横向控制结果转换成车队原点 `FleetTwist`；这些点不是物理轮轴，也不直接参与单车四轮解算。横向控制器与GCP到Twist转换必须使用同一控制点半径；具体车辆级配置值和实车验证仍待完成。
+- 每辆成员车都应作为反馈来源，但反馈职责必须分层：成员Detour位姿用于融合车队整体位姿和检查相对布局，单车轮速/舵角用于确认命令执行偏差，电机电流、扭矩或力传感信息用于负载与内力监控。相对位姿接近目标并不能证明没有内力，因此不能只依靠刚性连接或位姿误差判断负载均衡。
+- 第一版不把每车β作为复杂优化变量：`FleetController` 支持固定车队主要滚动方向 `beta_fleet`，`FleetPreparationCoordinator` 按布局换算成员 `beta_i` 并采用180°等效轴，`FleetRuntime` 已将停车预对齐、全员Ready和统一激活接入运行链。β是单车执行坐标系，不改变刚体分配得到的真实车体系 `BodyTwist`；只有出现复杂布局、整段方向变化、限位余量或频繁反号问题时，才增加轨迹级β候选搜索。
+- 旧版参考项目采用固定双车布局：各车由 `carWorld ∘ layout⁻¹` 反推车队中心，再对位置和圆周航向求平均；路径控制器以该虚拟中心跟踪轨迹。同时它可按 `fleetTarget ∘ layout_i` 生成每车理想位姿，并叠加Detour布局纠偏和邻车两腿检测纠偏，因此并非只控制平均中心。来源：`原版停车机器人/parkingrobot/ClumsyPilot/PilotDefinition.cs`、`ChassisController.cs`。
+- 旧版 `SetOriginBias(layoutX, layoutY, layoutTh)` 是把各车真实轮子统一表达在车队虚拟坐标系中，属于固定编队布局变换。旧版联动显式区分常规、蟹行和绕车队中心旋转三类模式；蟹行角可由动作或遥控给出任意值（`FleetCrabWalk` 默认45°），并在运动前以零速度对齐舵轮、运行时使用180°等效和轮速反号，但没有根据整段轨迹和每车约束自主求解β的统一规划过程。给定简单蟹行动作时，它与新版固定β可能产生相同的实际轮子姿态和车辆运动。
+- 旧版自动 `FleetCurveWalk`、`FleetCrabWalk` 会先以零速度下发初始GCP角，等待成员新鲜、布局正确、命令可行、舵轮到位和从车应用新序列后才开始运动；原地旋转通过 `RotateWheelsAligned` 和 `FleetMotionReleased` 做整队释放。普通手动入口仍有 `SendMotion` 本车舵轮未对齐时速度置零的门控，但不保证与自动动作相同的车队级同步屏障。
+- 旧版的全局与局部定位用途不同：自动模式的车队中心估计仍依赖Detour，与局部POS纠偏开关无关；邻车两腿检测只能提供相对间距和姿态信息，不能单独确定世界坐标中的车队中心。
+- 旧版单车几何控制器和原地自转直接读取 `DetourInterface.getCartLocation()`，未见当前新版的源时间对齐、跳变候选或任务坐标连续化；旧版宿主参考代码另有基于 `l_step` 和数据新鲜度减速/暂停并触发重定位的 `RelocalizationManager`。这只能说明旧版通过宿主安全状态机管理明显失效，不能据此认定Detour位姿天然连续；实车部署是否使用相同宿主版本和配置仍待确认。来源：`mdcstoolbox/Clumsy/MotionControllers/AbstractGeometricController.cs`、`原版停车机器人/parkingrobot/ClumsyPilot/Movements.cs`、`mdcstoolbox/Clumsy/HighLevelSecurity/RelocalizationManager.cs`。
+- 旧版的 `MultiVehicleUseDetect` 与 `MultiVehicleSyncUseDetour` 是彼此独立且默认关闭的开关，并非强制二选一。两者同时开启时，常规/蟹行的 `SendMotion()` 会直接将检测补偿与POS补偿逐分量相加，没有互斥或状态级融合；这不等于每次运行必然冲突，但存在重复修正、相互对抗和放大噪声的结构风险。来源：`原版停车机器人/parkingrobot/ClumsyPilot/PilotConfig.cs`、`PilotDefinition.cs`。
+- 旧版方案只作为设计参考，不直接移植：`GetLayoutPoseForCar()` 将成员写死为两侧镜像布局，车队几何通过 `SetOriginBias(layout)` 和 `ControlPointRadius=distance/2` 进入各车底盘解算；当两类局部纠偏均关闭时，成员一致性仍可能依赖共同开环命令和被搬运物的机械约束。
+
+## 待评估
+
+- 多车共同搬运时的车队参考点与固定GCP距离、逐成员能力/命令可行性限幅，以及带时间预测和异常成员隔离的鲁棒车队位姿融合；当前任意成员布局、确定性刚体分解和小范围队形误差闭环已有第一版实现。
+- 确定性刚体分配验证完成后，再评估集中式单步QP/HQP：安全和刚体可行性应作为硬约束或更高层级，相对布局、中心跟踪、平滑与能耗依次降低优先级；严格HQP不能仅靠单个加权QP的大权重近似。短时域MPC及舵轮动态延迟预测属于更后续阶段。
+- 负载共享和内力监控可用信号、阈值、降级与停车策略；当前项目尚未建立可确认的力/扭矩闭环。
+- 正式轨迹规划层与 `Trajectory2D` 的接入格式；当前 `TestTrajectoryFactory` 仅用于实验。
+- 是否长期保留旧版GCP/`SendMotion`后端，或增加经过充分验证的“车体Twist直接到各轮”的新后端。
+- 蟹行遥控中按半轮距/半轴距缩放舵角的映射是否符合统一曲率语义；这是遥控手感策略，不应与坐标变换混为一谈。

+# 关键接口与数据约定
+
+## 坐标系和单位
+
+`Shared/` 的统一约定：
+
+- 位置：m；线速度：m/s；角度：rad；角速度：rad/s。
+- 真实车体坐标系：X向前、Y向左、逆时针为正。
+- 原始世界坐标来自Detour；位姿在 `DetourVehicleStateProvider.ReadDetourObservation()` 边界由mm/deg转换为m/rad，再通过任务坐标变换生成连续控制位姿。
+- `AngleMath` 的弧度归一化范围是 `[-π, π)`，角度范围是 `[-180°, 180°)`。
+- `Pose2D` 表示局部坐标系在父坐标系中的位姿；变量名使用 `XxxInYyy` 说明关系。
+- `Twist2D` 不携带坐标系标签，必须由变量名、外层类型或接口契约说明。
+
+旧版 `CommonUsage` 底盘接口使用混合单位：轮子位置和 `ControlPointRadius` 为mm，`SendMotion` 舵角与 `CarSpeed.Vw` 为deg/deg/s，线速度为m/s。单位转换应只出现在Shared适配边界。
+
+## Shared 数据模型
+
+文件：`Shared/Models/MotionModels.cs`。
+
+| 类型 | 语义 |
+| --- | --- |
+| `Point2D` | 二维位置或向量，单位m |
+| `Pose2D` | 二维位置和朝向，单位m/rad |
+| `Twist2D` | 同一点处的 `Vx`、`Vy`、`Omega`，单位m/s、rad/s |
+| `VehicleLayout` | 单车车体系在车队系中的固定目标位姿 |
+| `FleetLayout` | 不可变的成员布局快照，构造时校验成员数量、车号唯一性和位姿有限值 |
+| `FleetMotionCommand` | 车队参考点及该点在车队系中表达的刚体速度 |
+| `FleetMemberCommand` | 指定车辆及其真实车体系中表达的成员中心速度 |
+| `FleetState` | 同一采样时刻的车队虚拟中心位姿和速度快照 |
+
+坐标变换集中在 `FrameTransform2D`；有限值检查集中在 `NumericGuard`；角度处理集中在 `AngleMath`。
+
+`FleetKinematics.Decompose()` 依据 `v_i = v_ref + omega × (r_i-r_ref)` 生成每车命令，再按 `VehicleLayout.PoseInFleet` 的朝向把线速度从车队系转换到成员车体系；所有刚性连接成员的 `Omega` 保持相同。
+
+`MultiWheelC/Fleet/FleetState.cs` 中，`FleetPoseInWorld` 表示车队虚拟中心位姿，其 `Yaw` 同时定义车队坐标系 `+X` 在世界系中的方向；车队系采用 `+X` 前、`+Y` 左、逆时针为正。`TwistAtFleetOriginInWorld` 与 `TwistAtFleetOriginInFleet` 是同一参考点、同一物理速度在两个坐标系中的表达，后者由前者和 `FleetPoseInWorld` 推导，不是第二份独立测量。`HasValidVelocityEstimate=false` 时速度按零保存，用于区分尚未形成可靠速度估计与真实零速。
+
+`FleetState.SampleTimestampSeconds` 表示主车/协调器生成该车队状态快照时的本机单调时间，不是Detour全局时间。各成员电脑的本机时钟和Detour `tick` 当前不能直接互相比较；未来接收层应另行保存来源时间并完成新鲜度和时间对齐。
+
+### `FleetLayoutCapture`
+
+文件：`MultiWheelC/Fleet/FleetLayoutCapture.cs`。
+
+- `FleetMemberPose`：用于布局采集的车号和成员世界位姿输入。
+- `FleetLayoutCaptureResult`：同时返回采集时刻的 `FleetPoseInWorld` 和固定的 `FleetLayout`；车队当前世界位姿不存入布局。
+- `Capture(members, leaderVehicleId)`：车队原点X/Y取成员车体中心的算术平均，Yaw取主车Yaw，并通过 `inverse(FleetPoseInWorld) ∘ VehiclePoseInWorld` 得到每车 `PoseInFleet`。
+- 空成员、非法或重复车号、非有限位姿、主车不存在均拒绝采集；主车缺失时不使用其他车辆降级代替。
+
+该接口是纯几何计算，调用者必须在外部保证成员位姿处于同一世界坐标系，并完成夹紧、静止、数据新鲜度和时间对齐检查；布局的存储与原子激活也不属于该类。
+
+## 车队通信与安全接口
+
+`Shared/Fleet/FleetProtocol.cs` 只定义与具体无线模块无关的值类型：
+
+- `FleetCommand`：任务号、主车命令序号、目标车号、命令类型、成员β、成员车体系速度、有效期和原因码。目标车号0表示广播。
+- `FleetMemberReport`：车号、任务号、本车报告序号、来源采样时间、公共世界系位姿/速度、状态有效性、本地任务阶段、最近执行命令序号和故障码；它同时承担心跳和命令确认。
+- `FleetCommandKind` 当前覆盖滚动准备、自转准备、激活、运动和停止；`FleetMemberState` 覆盖空闲、准备、就绪、活动和故障。
+
+`MultiWheelC/Fleet/IFleetTransport.cs` 仅提供 `SendCommand`、`SendReport`、`TryReceiveCommand` 和 `TryReceiveReport`。它不负责串口初始化、字节序列化、任务/序列校验、安全判定或时钟同步；测试项目的 `InMemoryFleetTransport` 按车号路由FIFO消息，广播只送从车，主车本地命令由 `FleetRuntime` 直接执行。
+
+时间语义分层：报告的 `SampleTimestampSeconds` 是来源车的采样时刻，真实跨机接收层必须换算到主车时间轴后才能用于 `FleetMemberStateSample` 对齐；`FleetMemberSafetyStatus.LastAcceptedReportTimeSeconds` 必须使用主车本地单调接收时间；`FleetMemberAgent` 的命令接收时间和截止时间必须使用本车本地单调时钟。Detour `tick` 不能直接替代这三类时间。
+
+`FleetSafetySupervisor` 只在主车侧检查成员缺失、任务不一致、通信超时、状态不可用和故障，并锁存首个 `ShouldStop` 原因；它不直接操作底盘。`FleetMemberAgent.UpdateCommandWatchdog()` 是每车本地最后一道失联保护，活动状态下命令过期或本地时钟倒退会立即 `StopImmediately()` 并进入 `Faulted`。运行循环即使没有收到新命令也必须周期调用该方法。
+
+### `FleetRuntime`
+
+- 构造时传入本车ID、主车ID、`IFleetTransport`、本车 `FleetMemberAgent` 和 `IVehicleStateProvider`；本车ID等于主车ID时，还必须传入 `FleetPreparationCoordinator`、`FleetCoordinator` 和 `FleetSafetySupervisor`。
+- `StartRollingPlan(planId, layout, trajectory)` 只允许主车调用；成员准备β直接取自 `FleetCoordinator.MotionDirectionInFleetRadians`，避免准备方向与控制方向出现两份配置。
+- `Update(currentTimeSeconds, deltaTimeSeconds)` 使用本机单调时间驱动准备超时、主车报告新鲜度和本地命令看门狗。主车缓存的远端报告采样时间必须已经换算到主车时间轴，当前运行层不会自行估计跨机时钟偏移。
+- `Stop(reason)` 正常取消本车任务；主车同时广播当前任务停止。运行状态覆盖 `Idle`、`Preparing`、`Ready`、`Active`、`Completed` 和锁存的 `Faulted`。
+- 第一版公开启动入口只支持固定布局滚动轨迹；协议和从车执行器虽已保留 `PrepareSpin`，但整队自转尚无对应主车任务入口。
+
+## 轨迹契约
+
+文件：`MultiWheelC/Trajectory/`。
+
+### `TrajectoryPoint`
+
+- `ArcLengthMeters`：按预定执行点序从起点累计的弧长，首点必须为0。
+- `PoseInWorld`：车体中心参考位姿；Yaw始终表示车头方向，不因倒车改为车尾方向。
+- `CurvaturePerMeter`：沿弧长增加/执行点序定义，左弯为正。
+- `ReferenceSpeedMetersPerSecond`：轨迹切线方向的有符号车体中心参考平移速度，绝对值是速度模长，正值前进、负值倒车、0停车。
+
+### `Trajectory2D`
+
+- 至少两个点，弧长严格递增，相邻位置不能重合。
+- 弧长增量必须与离散线段长度在容差内一致。
+- 当前是空间轨迹，以弧长插值位置、Yaw、曲率和参考速度；没有时间戳，也不是时间参数化轨迹。
+- `SampleAtArcLength()` 和 `TrajectoryProjector` 共用 `InterpolateSegment()`，避免两套插值语义。
+
+### `TrajectoryProjector`
+
+- 首周期可全轨迹搜索；后续控制器使用上次弧长附近窗口，当前常量为后退0.10m、前进1.00m。
+- 距离并列时优先接近上次进度，降低交叉或平行轨迹跳段风险。
+- `LateralErrorMeters` 相对轨迹点序判断左右，轨迹位于车辆左侧时为正。
+- `HeadingErrorRadians` 是参考车头航向减实际车头航向的最短角差。
+
+测试轨迹由 `Experiments/TestTrajectoryFactory.cs` 生成，不是正式规划层。直线和曲线速度同号；负速度表示倒车，测试工厂不支持在同一条曲线中直接切换前进/倒车方向。
+
+## 状态接口
+
+### `DetourInterface.getCartLocation()`
+
+当前引用接口返回的定位对象包含：
+
+- `x`、`y`：Detour世界坐标，单位mm。
+- `th`：车体航向，单位deg。
+- `tick`：定位源时间；实车静态记录确认可按`.NET DateTime.Ticks`转换，同时必须保留原始整数用于诊断。
+- `l_step`：Detour定位过程的质量/步骤相关指标，精确定义和正式阈值待Detour文档确认；实车正常静态基线包含2和周期性单帧3，不能将3直接判为异常。
+
+`DetourVehicleStateProvider` 使用 `x/y/th` 生成控制位姿，使用 `tick` 区分重复、新到和倒退帧，并保留 `l_step` 供诊断。`l_step` 当前不作为单一硬门限：实车数据中既出现过高 `l_step` 后恢复，也出现过低 `l_step` 但位姿创新异常的情况。状态时间仍使用本机单调 `Stopwatch`；`Experiments/DetourStaticDiagnosticTest.cs` 可只读记录原始字段、接口耗时、帧间差和轮组反馈。
+
+当前继续设计状态层所需的Detour侧最小信息是：`getCartLocation()` 返回的是可能重定位跳变的全局/map位姿还是连续里程计位姿；`tick` 对应采集、解算还是发布时刻及缓存语义；`l_step` 的状态含义；现有接口是否另有连续里程计位姿/速度或定位有效、重定位状态。无需以取得Detour源码为前提，部署版本、里程计和单线激光SLAM配置截图可用于核对实际运行配置。以上信息尚待Detour侧确认。
+
+### `IVehicleStateProvider`
+
+```text
+bool TryGetState(out VehicleState state)
+```
+
+返回 `false` 表示当前状态不可用；`ParkingGeometricController` 会主动停车、重置反馈控制器并等待下一周期恢复。
+
+### `VehicleState`
+
+- `SampleTimestampSeconds`：状态源单调时钟时间。
+- `PoseInWorld`：当前任务控制世界系中的车体中心位姿；初始化时与Detour世界系对齐，确认有限坐标阶跃后可通过内部变换保持任务连续，不保证始终等于原始Detour坐标。
+- `TwistInWorld`、`TwistInBody`：同一刚体速度的两种表达。
+- `HasValidVelocityEstimate`：速度反馈是否已建立有效时间基准；无效时构造器将速度置零。
+
+### 默认组合状态源
+
+`ParkingVehicleStateProviderFactory.Create()` 创建：
+
+- `DetourVehicleStateProvider`：读取Detour位姿，处理源时间、重复帧、运动合理性、预测创新、静止确认和跳变候选；候选确认期间使用轮组速度短时预测控制位姿。确认后的有限小坐标偏移可更新 `controlFromDetour` 以保持当前任务坐标连续，超限或未恢复时将状态置为不可用。
+- `WheelFeedbackVehicleStateProvider`：调用 `MultiWheelChassis.GetCarSpeed(true)`，低通滤波车体 `Vx`、`Vy` 和由deg/s转换为rad/s的 `Vw`。轮组估计有效后，最终 `VehicleState` 的 `Vx/Vy/Omega` 均使用滤波后的轮组反馈；首帧速度标记为无效，并由 `VehicleState` 对外置零。轮组 `Vw` 同时提供给Detour短时运动预测和动态航向合理性判断。
+
+默认滤波参数来自 `PilotConfig.ParkingControl.cs`：Detour线速度0.15s、Detour角速度0.20s、轮组反馈 `Vx/Vy/Vw` 统一为0.10s。
+
+跳变处理的重要边界：航向创新允许量随 `|Vw| × Detour源帧间隔` 增加；候选若在近似原地自转期间开始，则整个候选确认过程禁止自动改写任务坐标系。默认候选确认窗口为0.60s，窗口内输出轮组预测状态，超时后完整位姿安全返回不可用。
+
+完整轨迹控制仍通过 `TryGetState()` 要求位置和航向均有效。原地自转提供两种反馈模式：
+
+- `DetourAbsoluteHeading` 使用 `TryGetHeadingRadians()` 做世界航向闭环；仅位置异常时可继续，航向异常仍会停止。到达目标并停车后调用 `BeginPostRotationPositionRecovery()` 恢复完整位姿，恢复失败时不释放下一运动段。
+- `RelativeWheelOdometry` 使用 `TryGetWheelTwist(out Twist2D, out timestamp)` 直接读取并滤波轮组 `Vx/Vy/Vw`，按轮组采样时间梯形积分相对转角；活动自转期间不调用Detour，也不执行Detour停车后恢复。该模式用于允许约±5°误差的相对角动作，不能提供绝对世界航向校正，轮胎打滑和轮径误差会累积到角度结果中。
+
+`TryGetWheelTwist()` 是不依赖Detour的窄接口；首次尚未形成滤波样本时返回 `false`，其时间戳来自该状态源使用的本机单调时钟。
+
+`TrackingExperimentRecorder` 已记录原始/滤波轮组 `Vx/Vy/Vw`、轮组采样时刻、Detour `tick/l_step`、数据年龄和源帧间隔、轮速预测时刻、实际/允许的位置与航向创新、候选触发原因、估计器状态及不可用原因。创新和源帧间隔只在收到Detour新帧时更新；若CSV记录频率高于Detour帧率，后续记录行会重复最近一个新帧的诊断值，分析时应按 `DetourTickRaw` 去重或分组。
+
+## 控制接口
+
+### `PathTrackingContext`
+
+一次控制周期的只读快照，包含：受控刚体的车体系 `Twist2D`、速度有效标志、`TrajectoryProjection`、处理后的控制参考速度、预瞄曲率、真实 `deltaTime` 和运动方向β。该类型不依赖单车 `VehicleState` 或车队 `FleetState`。
+
+`ActualLongitudinalSpeedMetersPerSecond` 是完整车体平面速度沿β方向的投影：
+
+```text
+Vβ = cos(β)·Vx_body + sin(β)·Vy_body
+```
+
+因此45°/90°蟹行不能只使用车体 `Vx` 判断纵向速度。
+
+### `PathTrackingCore`
+
+`PathTrackingCore.Compute(Pose2D, Twist2D, bool, double)` 是单车与车队共用的纯轨迹跟踪周期：负责连续投影、距离保护、起步释放、终点制动/完成判断、曲率预瞄、横纵向控制和GCP分配，返回 `PathTrackingCycleOutput`。输出只包含周期结果、可选 `GcpMotionCommand`、投影和计算耗时；核心不读取状态源、不发送底盘命令，也不处理通信。
+
+状态暂时不可用时，外层调用 `PauseForUnavailableState()` 保留当前轨迹与投影连续性；明确失败或取消分别使用 `Fail()`、`Cancel()`。
+
+`ParkingGeometricController` 是单车适配层，负责读取 `IVehicleStateProvider` 并通过 `GcpCommandExecutor` 发送实体底盘命令。`FleetController` 是车队虚拟中心适配层，使用 `FleetState.FleetPoseInWorld` 和 `TwistAtFleetOriginInFleet` 调用同一核心。构造参数 `motionDirectionInFleetRadians` 定义固定的 `β_fleet`：核心按该方向投影实际纵向速度，GCP结果先解释为运动坐标系Twist，再通过 `R(β_fleet)` 转换成车队坐标系下、车队原点处的 `FleetMotionCommand`。`β_fleet=0` 保持常规前向语义；当前控制器不负责运行中切换β。
+
+当前速度闭环和执行边界的语义并不完全相同：纵向PID与Stanley实际速度分母使用 `Vβ`（Stanley也可按配置改用参考速度），而 `GcpMotionCommand.SpeedMetersPerSecond` 和旧版 `SendMotion.speed` 表示带行驶方向符号的车体中心平移速度模长。正常圆弧理想跟踪时 `Vy=0`，两者相等；只有横向误差共同转角产生非零 `Vy` 时，模长与 `Vβ` 才相差余弦因子。当前最大命令速度仍限制最终发送的模长。
+
+### `ILateralController`
+
+- `Compute(PathTrackingContext)` 返回 `LateralControlCommand`。
+- `Reset()` 清除跨周期状态。
+- 默认实现 `StanleyLateralController` 输出前后GCP角度：横向误差形成共同转角，航向误差和曲率前馈形成差动转角；倒车时按行驶方向修正符号。
+- `TrajectoryTrackingMovement.LateralControllerFactory` 是替换Stanley的动作级扩展点。
+
+### `ILongitudinalController`
+
+- `ComputeSpeedMetersPerSecond(PathTrackingContext)` 返回有符号中心命令速度。
+- 默认 `PidLongitudinalController` 使用轨迹参考速度前馈叠加实际速度PID反馈，带死区、积分限制和最大命令速度；参考明确为0时禁止反向速度纠偏。
+
+### GCP命令
+
+- `LateralControlCommand`：前后GCP目标角度，以及共同/差动分量。
+- `GcpCommandAllocator`：分别限制前后GCP角度并与纵向速度组合。
+- `GcpMotionCommand`：进入底盘执行前的有符号速度和前后GCP角度，SI单位。
+- `GcpCommandExecutor`：限制GCP角速度，保存 `LastRequestedCommand`/`LastSentCommand`，转换为 `Twist2D` 后执行。
+
+对称前后GCP位于当前运动系的 `(±R, 0)`。依据刚体速度关系 `v(point)=v(center)+ω×r`：
+
+```text
+Vfront = (Vx, Vy + ωR)
+Vrear  = (Vx, Vy - ωR)
+```
+
+因此 `Vy` 形成前后同向的共同转角，`ωR` 形成前后反向的差动转角。正常圆弧的理想车体速度为 `(v, 0, v·κ)`，曲率通过差动转角实现，并不要求车体系存在 `Vy`。
+
+## 底盘命令接口
+
+### `MultiWheelChassisAdapter.SendBodyTwist`
+
+输入始终是真实车体系 `Twist2D`：
+
+- 平移和角速度均近零：立即停车。
+- 平移近零、角速度非零：要求真实车体系已激活，调用 `SendXYThSpeed` 做纯自转。
+- 平移非零：使用动作开始前已经准备并激活的固定β运动系，转换为前后GCP方向并调用旧版 `SendMotion`。
+
+运动中不通过 `Vx/Vy` 猜测模式；模式由“停车→舵轮预对齐→`ActivateMotionFrame(β)`”显式确定。命令若几乎垂直于当前运动系X轴会停车并拒绝执行。
+
+`MultiWheelChassisAdapter` 构造时读取旧底盘 `GetOriginBias().Z`，按 `β=-biasZ` 同步内部缓存；这不是SLAM Yaw，也不会切换坐标系或转动舵轮。真正切换由 `ActivateMotionFrame(β)` 调用 `SetOriginBias(0, 0, -β)` 完成，旧底盘随后把真实轮位重新表达在β运动系中。
+
+滚动命令在 `SendRollingTwistInActiveMotionFrame()` 中按 `R(-β)` 将真实车体系平面速度转换到已激活运动系；角速度在二维旋转变换下不变。传给 `SendMotion` 的前后GCP角度均相对该运动系X轴，速度绝对值为 `sqrt(Vx²+Vy²)`，正负号取运动系 `Vx` 的方向。倒车方向由速度符号表达，GCP角度保持为相对行驶方向的等效机械方向，避免无意义旋转180°。
+
+### `MultiWheelChassis.SendMotion`
+
+输入是车体中心有符号平移速度模长、当前运动系中的虚拟前后GCP方向。前后GCP法线交点确定ICR；每个真实轮子使用其运动系位置计算切线舵角和半径速度比例。机械限位通过等效舵角/反向轮速解析，无法满足时返回失败原因。
+
+`SendMotion` 对每个轮子的目标速度应用 `AccPerSecond/DeAccPerSecond` 斜坡；加速或减速的判据是目标速度绝对值相对当前发送速度绝对值增大或减小。`PredefinedDriveStop()` 直接清零发送速度，不经过该减速斜坡。
+
+## 配置接口
+
+- `PilotConfig` 是Clumsy运行配置模型；`[FieldMember]` 字段提供默认值和宿主显示/持久化元数据。
+- `PilotDefinition.Conf` 是C层动作实际读取的运行配置对象。
+- `MultiWheelC/Configuration/PilotConfig.ParkingControl.cs` 集中停车状态估计、Stanley、纵向PID、原地自转、舵轮准备、GCP与完成条件参数。
+- 动作中的 nullable 覆盖字段用于特定动作段或测试；为空时使用车辆配置。车辆级限速和通用控制参数不应在普通实验中随意覆盖。
+- 多舵轮底盘几何和 `MaxSpeed/AccPerSecond/DeAccPerSecond` 由 `MultiWheelChassisInitializer` 从宿主工作目录相对路径 `../chassis.json` 加载，并覆盖 `AbstractChassis` 的字段默认值；启动输出会打印最终加载值。当前实车参考副本 `参考文档/chassis参考.json` 为 `AccPerSecond=0.3m/s²`、`DeAccPerSecond=1.0m/s²`，但只有部署端实际命名和路径正确的 `chassis.json` 会影响运行。
+- `参考文档/*.json` 是样例/实车复制资料；当前源码未发现这些JSON被 `PilotDefinition.Conf` 自动读取的入口。
+
+运行时配置文件格式、位置和覆盖优先级由外部Clumsy宿主决定，当前仓库内待确认。
+
+## M/C IO与MCU边界
+
+- C层 `PilotDefinition` 和M层 `DiverCartDefinition` 使用 `[AsUpperIO]`/`[AsLowerIO]` 对齐夹臂命令、驱动使能、位置反馈和车号等字段。
+- M层 `WheelSpeedDiagnosticLogger` 每次记录生成 `_can.csv` 和 `_snapshot.csv`：前者按CAN回调时刻保存八电机速度/位置与四舵角事件，后者按最多50Hz保存目标/实际舵角、目标角速度、PID/前馈/合成差速、限幅前后电机命令、速度/位置/电流反馈及各事件的本机单调时间、序号和数据年龄。MATLAB辨识时可使用 `TargetTh` 作为参考、`TotalDiff` 或 `Sent*` 作为执行输入、`ActualTh` 作为输出；左右轮公共/差速通道由方向统一后的左右命令和反馈在分析侧组合。
+- C层纵向辨识复用 `TrackingExperimentRecorder` 保存目标 `CommandVx`、Detour位姿和轮组原始/滤波速度；M层诊断中的 `SentSpeed*` 才是经过底盘速度斜坡与最终限幅后的执行输入。正式辨识应一组C层CSV对应一组M层CSV，并以首个非零发送命令边沿对齐两套本机时间。
+- `DiffSteerThresh` 通过 `PIDController.ChangeParameters()` 设置差速转舵PID的对称输出上限：例如配置0.3时，PID反馈项限制在[-0.3,+0.3]m/s。`MotorRoutine.UpdateDiffSteerWheelSpeeds()` 先将该反馈项与独立限幅的角速度前馈相加，再按左轮减、右轮加叠加到基础轮速；合成差速不会再次受 `DiffSteerThresh` 限制。最终八个单轮命令还会在 `MCURoutine` 中分别受 `SendThresSpeed` 限制。因此当前前馈增益为0、基础轮速为0且 `SendThresSpeed` 不低于0.3m/s的静止模式切换实验中，配置 `DiffSteerThresh=0.3` 可视为实际转舵差速的±0.3m/s上限；车辆行驶或重新启用前馈时，不能把它误当作每个电机最终总速度的唯一上限。
+- `DiverCartDefinition.CommunicationInit()` 默认通过Windows `COM4`、`1,000,000 baud` 打开MCU桥；`MCUPort` 是可配置初始化参数。
+- MCU内部配置为逻辑端口0：CAN `500,000 bit/s`；逻辑端口1～3：串口 `9,600 bit/s`。`MCURoutine.BatteryPortIndex = 3` 指MCU桥逻辑端口，不等同于Windows `COM3`。
+- CAN命令/反馈范围集中在 `MCURoutine.cs`：驱动命令 `0x201～0x20A`，速度/位置反馈 `0x281～0x28A`，状态 `0x181～0x18A`，舵角 `0x18B～0x18E`，远程帧 `0x701～0x70A`。

+# 项目概览
+
+## 项目定位
+
+`MyParking` 是停车机器人控制软件的当前正式开发版本，主体为 C# 插件工程。项目目标是让多舵轮停车机器人完成底盘运动、车辆状态获取、轨迹跟踪、原地自转和后续停车作业；当前研发重点仍是单车闭环和实车联调，多车协同已有纯计算骨架但尚未形成可运行实现。来源：`README.md`、`MultiWheelC/PilotConfig.cs`、`MultiWheelC/Fleet/`、`Shared/Fleet/`。
+
+项目不是可直接 `dotnet run` 的独立应用：
+
+- `MultiWheelC.dll` 由 Clumsy 宿主加载，提供 C 层动作、控制和 `MovementTest` 入口。
+- `MedullaAdapter.dll` 由 Medulla 宿主加载，负责 M 层硬件通信和周期逻辑。
+- `CommonUsage.dll` 提供通用底盘模型和四轮几何解算。
+
+对应入口类型为 `MultiWheelC/PilotDefinition.cs::PilotDefinition` 和 `MedullaAdapter/DiverCartDefinition.cs::DiverCartDefinition`；仓库中没有 `Program.Main`。
+
+## 车辆与业务场景
+
+- 代码接口面向四个可转向轮组，并暴露8个驱动电机的位置/速度反馈和4个舵角反馈。M/C IO定义见 `PilotDefinition`、`DiverCartDefinition`。
+- 车体支持正常前后行驶、倒车轨迹、任意固定运动方向β下的滚动运动、蟹行和停车后原地自转。主要入口见 `MultiWheelC/Movements/` 和 `MultiWheelC/Experiments/`。
+- 夹臂速度、位置、限位和报警IO已经接入，但轮胎识别、自动钻车、释放车辆和完整停车作业状态机尚未在当前新版流程中完成。来源：`PilotConfig.cs`、`PilotDefinition.cs`、`README.md`。
+- 多车已具备 `FleetLayout`、`FleetState`、`FleetController` 和 `FleetKinematics` 组成的纯计算链；多车配置仍位于 `PilotConfig.cs` 的 `#if false`，且状态聚合、通信、成员纠偏、安全协调和实体发送尚未接入，因此不能把当前代码视为已支持可运行的多车编队。
+
+## 整体运行流程
+
+典型新版轨迹跟踪流程：
+
+1. Clumsy 宿主通过 `MovementTest` 或动作计划启动 `TrajectoryTrackingMovement`。
+2. 动作停车并通过 `PrepareWheelsForward` 将舵轮预对齐到本段运动方向β。
+3. `ParkingVehicleStateProviderFactory` 组合 Detour 位姿和轮组反馈速度。
+4. `ParkingGeometricController` 完成轨迹投影、横纵向控制、GCP分配和完成条件判断。
+5. `GcpCommandExecutor`、`MultiWheelChassisAdapter` 将SI单位命令转换到当前运动坐标系，再调用 `CommonUsage.Chassis.MultiWheelChassis`。
+6. M层周期逻辑将底盘和夹臂命令发送到MCU/CAN，并把反馈通过宿主IO返回C层。
+
+详细调用链见 `architecture.md`，接口和坐标语义见 `interfaces.md`。
+
+## 当前阶段
+
+- 单车基本运动、新版轨迹跟踪、倒车直线、45°蟹行直线、原地自转和组合动作均有宿主测试入口。
+- 新版控制默认采用 Stanley 横向控制和 PID 纵向控制；轨迹实验和控制周期诊断可输出CSV。
+- 当前代码能力不等于完整实车验收，特别是高速、曲线倒车、蟹行曲线、长期稳定性和异常工况仍需单独验证。
+
+## 待确认
+
+- Clumsy/Medulla 宿主的正式版本、插件部署目录和启动顺序。
+- `PilotDefinition.Conf` 在实车上的持久化文件位置、加载时机和发布流程。
+- 真实车辆最终几何参数、舵轮零位/限位和不同车辆配置的权威来源。
+- 完整停车业务的产品流程、安全状态机和验收指标。

+# 问题与验证状态
+
+## 已解决（代码层）
+
+### 轨迹数值检查和插值入口重复
+
+- 现象：多个轨迹文件分别实现有限值检查和插值，语义容易漂移。
+- 处理：Shared增加 `NumericGuard`；轨迹采样和投影共用 `Trajectory2D.InterpolateSegment()`。
+- 位置：`Shared/Validation/NumericGuard.cs`、`Trajectory2D.cs`、`TrajectoryProjector.cs`。
+- 验证范围：代码结构已统一；无自动化单元测试记录。
+
+### 交叉/邻近轨迹可能发生投影进度跳变
+
+- 原因：每周期在全轨迹搜索最近线段可能跳到空间上接近但进度不连续的线段。
+- 处理：首周期全局搜索，后续按上次弧长使用后退0.10m、前进1.00m窗口，并在距离并列时优先原进度。
+- 位置：`TrajectoryProjector`、`ParkingGeometricController`。
+
+### 倒车曲率和反馈符号不完整
+
+- 处理：轨迹使用有符号参考速度，Yaw保持车头方向；横向误差继续相对轨迹执行点序定义，共同转角不再乘行驶方向，航向修正和曲率前馈保留倒车反号。
+- 现有入口：`NewControllerReverseStraight4mTest`。
+- 验证：`MultiWheelC.Tests` 的8个无实车符号场景通过；2026-08-19第六轮实车记录中，倒车零偏置终点误差约15.9mm和12.8mm，+150mm偏置横向误差由约-150.4mm收敛到-5.0mm、终点误差约18.1mm，已与正向直线精度接近。
+- 限制：直线倒车有测试入口，曲线倒车仍归入待验证。
+
+### 终点零速参考可能提前停车且无法收敛
+
+- 处理：增加终点制动预瞄和单向低速逼近；越过终点不反向修正。
+- 完成条件：剩余弧长、终点距离、终点航向和β方向轮组实际速度全部满足。
+- 位置：`ParkingGeometricController`、`PilotConfig.ParkingControl.cs`。
+
+### 状态配置和终点速度来源不一致
+
+- 处理：统一通过 `ParkingVehicleStateProviderFactory` 创建状态链；终点速度使用Vx/Vy沿β投影，不再让Detour横向速度单独影响普通前进判停。
+- 后续补充：`WheelFeedbackVehicleStateProvider` 已保留并滤波轮组反馈Vy，支持蟹行纵向速度投影。
+
+### 动作开始/结束时舵轮模式不明确
+
+- 处理：轨迹跟踪开始前自动准备β方向；原地自转先准备自转姿态，完成后回正；组合计划在运动前预检全部段。
+- 位置：`PrepareWheelsForward`、`TrajectoryTrackingMovement`、`MultiWheelRotateInPlace`、`MotionPlanExecutor`。
+
+### Detour持续小阶跃会直接扰动控制轨迹
+
+- 处理：状态层已分离Detour原始坐标与任务控制坐标；疑似阶跃期间使用滤波后的轮组 `Vx/Vy/Vw` 短时预测，有限小偏移经连续帧确认后更新坐标变换，大幅或超时未恢复的变化返回状态不可用。
+- 自转保护：动态航向阈值考虑实际轮组Vw和Detour源帧间隔；近似原地自转期间禁止自动吸收坐标偏移；位置单独异常时航向闭环可继续，到位停车后再恢复完整位姿，未恢复时阻止下一运动段。
+- 位置：`DetourVehicleStateProvider`、`WheelFeedbackVehicleStateProvider`、`MultiWheelRotateInPlace`、`PilotConfig.ParkingControl.cs`。
+- 验证：第三轮实车组合动作中发生一次约47mm/3.44°的原始坐标变化，自动连续化计数增加后控制轨迹保持连续，动作最终以约24.7mm剩余距离、2.8mm横向误差完成。
+
+### Detour自转退化会中断允许小角度误差的相对自转
+
+- 处理：`MultiWheelRotateInPlace` 增加 `RelativeWheelOdometry` 反馈模式，直接读取并积分滤波轮组 `Vw`；活动自转期间不调用Detour。原有 `DetourAbsoluteHeading` 模式继续用于需要世界绝对航向的任务。
+- 验证：2026-08-21第七轮包含19份轮组里程计自转记录，其中17份表现为正常停车并完成舵轮回正；这17份中轮组积分转角与Detour原始航向变化的绝对差中位数约0.89°、最大约3.07°。同批Detour原始位置端点变化中位数约56mm、最大约298mm，说明轮组模式确实绕开了自转期间的Detour退化依赖。
+- 限制：CSV尚未记录请求角度、内部积分角和明确完成原因，因此上述数据不能作为目标角精度的正式验收；另有2份记录未完成回正，属于手动停止、小角度超时或其他原因仍待确认。轮组积分也不能替代绝对世界航向。
+
+## 待解决
+
+### 完整停车作业流程尚未实现
+
+- 缺少或未接入新版流程：轮胎识别、自动钻车、夹抱/释放动作编排、完整安全状态机。
+- 现有 `PilotConfig` 和IO字段不能视为业务流程已经完成。
+
+### 多车执行链仍未完成
+
+- 纯计算链 `FleetState → FleetController → FleetMotionCommand → FleetKinematics.Decompose()` 已实现，并有6个车队控制周期场景和4个刚体分解场景通过。
+- `PilotConfig.cs` 的多车区域在 `#if false` 中，不参与当前编译。
+- 当前仍没有布局采集/激活、车队状态估计、通信接收与时间对齐、相对布局闭环、能力限幅、安全降级、成员底盘发送和多车实车测试闭环，因此不能把纯计算层视为可运行的多车功能。
+
+### 轮组速度初始化回退语义不一致
+
+- `WheelFeedbackVehicleStateProvider` 在轮组首帧无效时局部选择Detour `Omega`，但随后以 `hasValidVelocityEstimate=false` 构造 `VehicleState`；`VehicleState` 会把整份速度对外置零，因此该Detour角速度回退实际不可见。
+- 影响仅限轮组滤波尚未形成有效采样的初始化阶段；应确认期望是保持整份速度无效并置零，还是允许单独提供有效的Detour角速度，再决定是否修改代码和注释。
+
+### Detour跳变判据和动作段衔接仍需收敛
+
+- 2026-08-19第四轮记录包含16次独立原地自转：4次未出现候选、3次候选后恢复、9次因候选超时变为不可用，共25个候选片段。全部由 `PositionInnovationExceeded` 触发，没有 `HeadingInnovationExceeded`；航向创新峰值约7.1°，动态允许量约7.5～9.3°，说明当轮航向动态判据不是主要失败点。
+- 候选开始时Detour单帧平移中位数约53mm、最大约162.3mm，轮组 `Vx/Vy` 接近零；Detour新帧间隔约98.2～134.4ms，中位数约114.4ms。候选开始时 `l_step` 为2～83，其中9/25发生在 `l_step<=3`，另有 `l_step=61` 的自转未触发候选，继续证明 `l_step` 不能单独作为有效性门限。
+- 同轮7次直线中6次完成，其中2次完成有限坐标连续化；1次在约190mm原始阶跃后安全失败。组合动作完成，仅出现约47.7mm的短候选并自行清除。小范围连续化已有正面证据，大幅阶跃仍应保持安全边界。
+- 已实施“自转期间位置/航向分离、停车后再恢复位置”的动作衔接，编译和统一打包通过，但尚待实车验证。预期它解决位置单独异常导致的自转中断，不代表已经消除Detour原始位置阶跃。
+- 当前实现先读取Detour观测，再把轮速预测推进到本机当前 `Stopwatch` 时刻并比较两者；Detour观测对应的源时刻通常更早，因此比较时刻尚未严格对齐。0.4m/s且Detour约0.11s一帧时，这种时序差可产生约44mm表观位置创新，是固定40mm阈值可能过严的重要原因。短期可评估有界的“基础余量 + 平面轮速 × 源帧间隔”，但成熟修正应保存短时轮速/里程计历史，将观测与同一源时刻的预测比较，再把校正状态预测到当前时刻；该方案尚未实施。
+- 健康 `l_step` 下仅凭预测创新不应轻易自动改写坐标系；在完成同一时刻比较前，不继续通过反复放宽阈值堆叠补丁。
+- 不建议通过全局放宽0.60s确认窗口、40mm残差或允许自转期间完整坐标修正来掩盖问题。
+- 2026-08-19第六轮记录确认普通正向/倒车直线、曲线和小范围运动中坐标连续化总体可用，主要剩余失败集中在原地自转：有样本在 `l_step=94` 时连续3个Detour新帧航向创新超限，状态层先短时使用轮组Vw预测，第三帧才安全终止，说明单帧航向容错已按设计生效；另有约163mm、207mm的位置不连续或候选不稳定导致停车后恢复失败。
+- 当前决定：保持普通运动150mm自动连续化上限、自转最大角速度30°/s和角加速度40°/s²，不以全局放宽阈值或提高自转速度掩盖Detour退化。允许相对角误差的动作可选已实现的轮组里程计模式；必须闭环到绝对世界航向时，持续航向异常仍需要Detour质量/重定位语义或额外可信绝对航向来源才能进一步收敛。
+
+### 自动化测试和CI覆盖有限
+
+- 现有 `[MovementTest]` 是Clumsy宿主人工/实车入口，不是 `dotnet test`。
+- `MultiWheelC.Tests` 是不进入正式打包的独立可执行回归项目，现已覆盖Stanley前进/倒车横向符号的8个场景；应长期保留其源码，`bin/obj`仅为可删除编译产物。
+- 轨迹数学、坐标变换、状态跳变过滤和终点策略仍缺少标准测试框架下的可重复单元测试，当前也没有CI。
+
+### 运行和发布信息不完整
+
+- 宿主版本、正式插件目录、启动顺序、运行时配置文件位置和发布审批流程待补充。
+- `mcu_serial_bridge.dll` 不在当前源码目录，实车运行依赖外部部署。
+
+## 待验证
+
+### Detour静态基线与运动跳变条件
+
+- `Experiments/DetourStaticDiagnosticTest.cs` 已提供只读宿主测试，记录 `x/y/th/tick/l_step`、数据年龄、接口耗时、帧间差、四轮反算 `Vx/Vy/Vw` 及单轮反馈。
+- 2026-08-18约881s静态记录中没有复现5～7cm阶跃：Detour新帧最大位移9.21mm、2s前后中值最大持续偏移6.11mm，前后30s位置中值变化约15.5mm；该结果是当前环境的正常静态基线，不证明运动中阶跃已经消失。
+- 同次记录确认接口无失败或乱序，Detour实际新帧间隔中位数约109.94ms（约9Hz），数据年龄中位数57.19ms、最大134.49ms；`getCartLocation()`调用本身中位耗时仅0.0139ms，说明接口主要返回缓存的最新定位。
+- 静止时直接差分Detour位姿仍产生表观速度：线速度中位数约0.0132m/s、P95约0.0320m/s，角速度绝对值P95约0.680°/s；继续使用轮组反馈作为速度闭环来源是合理的。轮组反算在本次静态记录中基本为零，但仍需运动实验验证。
+- `l_step` 正常基线主要为2，并约每30s出现一个新帧值3，且未与明显位姿变化相关；精确定义、异常阈值以及Detour是否提供显式重定位/坐标重置状态仍待确认。
+- 运动记录进一步表明 `l_step` 与位姿创新并非一一对应。建议仅将其作为分级健康信号：低值稳定可支持恢复判断，高值持续且同时存在异常创新时才支持停车；实际分级阈值仍需结合部署端Detour/MDCS版本确认。
+- C层轨迹CSV现已同时记录原始/滤波轮组 `Vx/Vy/Vw`、轮组采样时刻、Detour源帧间隔和预测时刻、实际/允许的位置与航向创新、候选触发原因、估计器状态及不可用原因。该记录解决了字段缺口，但Detour源 `tick` 与本机单调时钟/轮组采样时钟之间尚未建立统一时间轴，仍需通过新实验和Detour `tick` 语义确认后才能定量评价预测误差。
+
+### 控制周期和舵轮响应
+
+- 代码已经记录控制周期分段耗时、请求/限速后GCP命令和四舵角；M层已有轮速/舵角诊断CSV。
+- 差速转舵角速度前馈实现仍保留0.03m/s独立限幅，但当前源码默认增益为0，作为对象辨识基线；曲率预瞄默认0.15s/0.12m。
+- 历史轨迹实验所称“约0.46s延迟”是 `TargetTh` 与 `ActualTh` 连续曲线的最佳时间平移量，反映当时工况下的等效跟随滞后，并非命令下发后等待0.46s才开始转动的纯死区时间，也不是任意目标角的固定到位时间。它与旧纯P近似模型约0.49s的90%响应时间数值接近，但两者指标不能等同；后续应分别报告目标变化至首次运动的启动时间、10%～90%上升时间、进入规定角差的稳定时间和连续曲线相位滞后，并在控制器或工况改变后重新测量。
+- 2026-08-19第六轮共9131个轨迹控制周期：周期中位数约31.24ms、P95约32.68ms、最大约59.44ms；控制计算总耗时中位数约0.12ms、P95约0.22ms。当前C层计算不是主要周期瓶颈，历史约110ms现象不应继续归因于控制算法计算量。
+- 2026-08-25静止诊断确认：目标角和角速度前馈均为零时，右后轮仍可形成约1s量级的持续差速转舵往复；死区由0.1°增至0.5°后，另外三轮均停止输出，但一次自转模式切回正常模式后的右后轮仍在约-1.9°至+2.9°间振荡。约2°的瞬态偏差本身不能证明硬件故障，待定位对象是仅该轮不收敛的闭环动态差异；应先用降低公共比例增益的重复切换实验区分控制稳定裕量，再对四轮分别辨识延迟、增益、摩擦和方向不对称，明显离群轮组先排查编码器、机械间隙和低速驱动响应。
+- 舵轮辨识数据共有三次物理实验：第一次为Kp=0.0035、死区0.1°、前馈0、约49.6V；第二次为Kp=0.003、死区0.5°、前馈0、约49.5～49.6V，因Kp和死区同时变化而排除在主辨识之外；第三次为重新采集的Kp=0.003、死区0.1°、前馈0，电压中位数约52.0V、范围约51.3～54.7V。`data_process/系统辨识实验-舵轮延迟/prepare_steering_iddata.m` 当前明确以第一次为Est、第三次为Val，因此“第二个处理批次”是第三次物理实验，不能与第二次0.5°实验混称。第一次与第三次统一了死区但电压不同，不是严格的仅Kp变化A/B实验，验证结果需要同时考虑供电、负载和机械状态差异。
+- 第三次验证数据中RR、尤其RRL通道被初步观察到低速跟随偏弱、电流升高及随后突发运动；该现象尚需用原始snapshot与CAN事件时间线复核。在复核前不应用该轮的异常验证结果调整全车公共PID，也不应据此否定LF/LR/RF的正常辨识结果。
+- 2026-08-27静止模式切换A/B表明，在公共 `Kp=0.0042` 不变时，同时启用0.5°/0.8°/3周期到位迟滞和0.15s模型逆前馈后，约69°、90°和20.85°动作的 `t90` 分别约缩短17%、18%和44%，进入±2°时间约缩短22%、19%和45%，最大超调也有所下降；当前数据缺少“只启用迟滞、关闭前馈”组，因此不能把总改善严格拆分到单项功能。
+- 同批日志显示M层差速转舵周期中位数约49.6ms，3个稳定周期在实车上约150ms而不是按75ms估算的225ms；到位停止区使末端误差中位数上升到约0.4°，并仍存在少量轮组0.8～1.6°未完全收敛样本，后续参数调整应以重复实车数据为依据。
+- 不同速度、载荷下的舵轮物理响应和前馈参数仍需按具体工况验证。
+- CAN/MCU正常运行逻辑风险较高；除诊断外不应在没有明确方案和实车回退措施时修改。
+
+### 尚未覆盖的运动工况
+
+- 曲线倒车。
+- 45°/90°蟹行曲线及不同β下的机械限位。
+- 非零β曲线中 `MultiWheelChassis.GetCarSpeed(true)` 的坐标一致性：`SetOriginBias` 会旋转 `sw.Position`，需要确认 `ReadAngle()` 返回值在该解算中的参考系与之匹配；当前不能仅由蟹行直线推断曲线速度反馈正确。
+- 0～1.2m/s范围内曲率预瞄、速度滤波和GCP角速度限制的参数适用性。
+- 高速、低附着、载车后质量/惯量变化、定位丢失和急停恢复。
+
+### 参数与实车配置一致性
+
+- `参考文档/*.json` 是否与当前实车配置一致待确认。
+- `PilotDefinition.CarLength/CarWidth`、宿主底盘轮子布局、`ControlPointRadius`、舵轮零偏和机械限位需要按车辆编号核验。
+
+## 排障入口
+
+- C层轨迹CSV：`TrackingExperimentRecorder`，默认宿主目录 `TrackingExperiments/`。
+- C层Detour静态诊断：`DetourStaticDiagnosticTest`，默认宿主目录 `DetourStaticDiagnostics/`。
+- C层周期耗时：`ParkingGeometricController.LastCycleTiming` 和 `*_timing.csv`。
+- M层轮速/舵角：`StartWheelSpeedDiagnostic()` / `StopWheelSpeedDiagnostic()`，默认 `logs/wheel-speed/`。
+- 底盘分解失败：`MultiWheelChassisAdapter.LastFailureReason`、`GcpCommandExecutor.LastFailureReason`。
+- 状态失败：`DetourVehicleStateProvider.LastFailureReason`、`WheelFeedbackVehicleStateProvider.LastFailureReason`。

+- 前进4m、倒车4m、45°蟹行4m、直线-左半圆-直线和组合运动宿主测试入口。
+- Detour位姿与轮组反馈组合状态源：位姿来自Detour；轮组估计有效后，控制状态的Vx/Vy/Omega均来自滤波后的轮组反馈，Vw同时用于短时位姿预测和动态航向合理性判断。
+- Detour源 `tick/l_step` 诊断、跳变候选确认、有限小偏移任务坐标连续化、自转期间禁止自动吸收偏移，以及超时状态不可用保护。
+- 起步释放、曲率前馈预瞄、GCP角速度限制、终点制动预瞄和单向低速收敛。
+- 原地自转舵轮准备、航向PID、超时保护和完成后回正；自转期间位置/航向有效性已分离，到位停车后才恢复完整位姿并决定是否释放下一段。
+- Detour单帧航向异常已增加连续帧/短时预测确认；第六轮实车数据确认前两帧异常由轮组Vw预测承接，持续到第三个异常新帧时才安全终止。
+- 原地自转已增加 `RelativeWheelOdometry` 模式和不依赖Detour的 `TryGetWheelTwist()` 接口；第七轮19份记录中17份表现为正常停车回正，轮组积分与Detour原始航向变化绝对差中位数约0.89°、最大约3.07°，但目标角精度尚缺专用字段正式验收。
+- C层轨迹/周期CSV与M层轮速/舵角诊断记录。
+- M层差速转舵已加入默认关闭、可独立回退的四轮到位迟滞和模型逆前馈；当前实车参考配置采用公共纯P `Kp=0.0042`、0.5°/0.8°/3周期到位判断及 `687.06/0.15s/0.03m/s` 逆前馈参数，首轮模式切换A/B已确认响应时间和超调整体改善。

+- 本次建立工作区/项目AGENTS导航和 `docs/` 按需知识库。
+
+以上表示代码入口存在，不表示全部实车工况已经验收。
+
+## 当前进行方向
+
+- 普通正向/倒车直线、曲线和小范围运动中坐标连续化已基本可用；允许小角度误差的相对自转已有轮组里程计模式，必须对准绝对世界航向时仍受Detour偶发持续退化限制。
+- 暂时冻结普通运动跳变阈值和30°/s、40°/s²自转参数，等待Detour接口语义后再决定是否实施自转结束后的条件化仅位置连续化或调整航向恢复策略。
+- Detour对接最小问题已整理到 `docs/detour-information-checklist.md`，不要求取得源码。
+- 验证非零β运动系，当前已有45°蟹行直线入口；曲线蟹行仍需设计实验。
+- 多车共同搬运的固定布局滚动任务已在内存传输下完成端到端贯通。当前重点转为真实无线链路和工程接入：确认无线参数与帧格式，实现串口 `IFleetTransport`，接入公共坐标系成员状态和主车时间轴，再通过静止状态机与低速双车逐级验证。QP/HQP不作为第一版前置条件。
+- 车队状态估计第一版保留“成员状态先经单车状态估计处理、车队层做时间对齐与刚体一致性检查、候选中心等权/圆周平均”的保守方案；暂不重复实现单车Detour跳变逻辑，也不在运行链和实车数据建立前加入复杂鲁棒优化。后续内部融合升级应尽量保持 `FleetStateEstimateResult`、`FleetState` 和 `MemberErrors` 外部接口不变。
+- β在多车中定位为单车执行坐标系而非车队核心优化量：常规、斜行和横移动作先确定车队主要滚动方向，各车按布局朝向换算本地β，停车预对齐并经车队同步屏障统一释放。轨迹级β搜索只作为机械余量或复杂方向变化下的后续增强。
+- 当前单车实验工作转入纵向系统辨识：先固定实车 `AccPerSecond=0.3m/s²`、`DeAccPerSecond=1.0m/s²`，以M层最终发送速度为输入、轮组反馈速度为输出，取得可重复模型后再调整纵向控制、启动/停车策略和加减速度参数；横向辨识随后进行。
+
+## 阻塞/待确认
+
+- Clumsy/Medulla正式宿主、插件部署和配置持久化说明未纳入仓库。
+- 完整停车业务流程和验收指标未确认。
+- 最小内存消息契约已经确定，但真实无线串口的端口参数、帧格式、序列化/校验和跨机时钟换算尚未实现；成员状态实际采集方式、布局原子激活接口、刚体误差实车阈值、夹紧/报警状态来源和故障降级策略仍待确认。
+- 各车经过独立 `_controlFromDetour` 任务坐标连续化后的位姿如何统一到同一公共车队坐标系仍待验证。车队参考点和纯几何采集方法已经确定，运行布局应在夹紧后生成不可变快照并由上层整体激活。
+- 最新实车实验数据对控制周期与舵轮滞后的结论尚未沉淀为可复核结果。
+- Detour `l_step` 精确定义、显式重定位/坐标重置状态和部署端MDCS恢复策略待确认；当前不能把 `l_step<4` 当作唯一有效性条件。
+- Detour `getCartLocation()` 的位姿坐标系、`tick` 采样/解算/发布语义、是否已有独立连续里程计或定位状态接口，以及部署版本和实际里程计/SLAM配置待确认。
+- Detour原地自转时 `l_step` 大幅上升、100～200mm级位置不连续和连续航向创新异常的内部原因待Detour负责人说明；仅凭当前位姿接口无法保证持续航向异常时仍可靠完成绝对角度闭环。
+- Detour源 `tick` 与本机单调时钟、轮组采样时刻尚无统一时间轴；当前创新比较可能包含数据年龄造成的表观误差。
+
+## 建议下一步
+
+1. 按 `docs/detour-information-checklist.md` 确认 `getCartLocation()` 字段、`tick`、`l_step`、定位延迟、重定位行为和质量状态接口。
+2. 在Detour信息返回前不继续全局放宽状态估计边界，也不提高自转角速度/角加速度；现有偶发定位不可用保持安全停车。
+3. 为轮组里程计自转CSV补充请求角度、内部积分角、完成/超时/手动停止原因，按固定目标角重复验证误差和重复性；绝对航向任务继续保留Detour模式，不用轮组积分冒充世界航向。
+4. 为轨迹插值/投影、坐标变换、状态跳变候选和终点策略继续补充不依赖宿主的数学回归测试。
+5. 确认无线模块的Windows COM端口、波特率、数据位、停止位、校验方式、收发模式和模块配置；定义带版本、长度、类型、任务/序列号及CRC的最小字节帧。
+6. 实现串口版 `IFleetTransport`，先只做主车心跳/命令和从车状态报告的静态通信测试，测量丢包、乱序、延迟和断线；不得绕过现有命令有效期与本车看门狗。
+7. 接入C层正式车队动作入口、成员状态实际来源和主车接收时间轴，保证 `FleetMemberReport` 位姿处于同一公共世界坐标系，远端采样时间已换算为主车时间后再形成 `FleetMemberStateSample[]`。
+8. 先验证静止布局建立、β准备、全员Ready、统一激活和停止，再进行空载低速双车直线与圆弧；共同搬运前补齐夹紧/报警输入和可立即停车措施。
+9. 记录各成员候选中心、数据年龄、状态来源、布局误差和减速/停车原因。只有数据证明当前等权融合频繁被单成员异常拖累时，再增加车队预测、逐成员门控和鲁棒加权。
+10. 先对纵向辨识两个入口各做一次0.05m/s低速流程验证，再在0.1/0.2/0.3/0.4m/s下采集当前固定配置的重复实验；每次单独保存C/M两份CSV，确认正向模型后再决定倒车补测和参数A/B。

+结论：`MultiWheelC\Fleet` 当前的数学链路作为“第一版组件”是成立的，现有 Fleet 数学测试共47个场景全部通过，没有发现明显的坐标系或符号错误。但它还不是可以直接上双车实车的完整工程方案，`FleetStateEstimator` 的等权平均尤其需要增加鲁棒性。
+
+## 正负平均为0是不是问题
+
+不一定，很多时候这正是期望结果。
+
+假设两辆车反算出的车队中心分别为：
+
+```text
+车辆1候选中心：+20mm
+车辆2候选中心：-20mm
+```
+
+平均得到：
+
+```text
+车队中心：0mm
+```
+
+但代码随后还会计算每辆车相对于这个中心的布局误差：
+
+```text
+车辆1相对误差：+20mm
+车辆2相对误差：-20mm
+```
+
+所以并不是误差消失了，而是被分成了：
+
+```text
+公共分量：车队整体中心运动
+相对分量：成员之间的队形变形
+```
+
+这正好符合当前架构：
+
+- 公共分量交给 `FleetController` 控制车队中心；
+- 相对分量交给 `FleetCoordinator` 减速，以及 `FleetMemberCommandCorrector` 小幅纠偏。
+
+如果两辆车反算结果都是 `+20mm`：
+
+```text
+平均中心：+20mm
+成员相对误差：接近0
+```
+
+这表示整个车队共同移动了20mm，而队形没有变，也符合物理意义。
+
+## 当前不是“无条件直接平均”
+
+当前 [FleetStateEstimator.cs](/D:/Users/Desktop/入职培训/停车机器人/MyParking/MultiWheelC/Fleet/FleetStateEstimator.cs:277) 实际执行的是：
+
+1. 将成员状态对齐到统一时刻。
+2. 每辆车根据固定布局反算候选车队中心。
+3. 检查任意两辆车反算的中心位置差和航向差。
+4. 差异超过阈值，直接返回状态不可用。
+5. 只有所有候选结果基本一致，才平均：
+   - X/Y算术平均；
+   - Yaw圆周平均。
+6. 根据融合后的中心重新计算每辆车的布局误差。
+
+所以如果：
+
+```text
+车辆1：+200mm
+车辆2：-200mm
+```
+
+两者相差400mm，只要超过 `_maximumPositionDisagreementMeters`，代码会在平均前拒绝本周期状态，不会把它们平均成0后继续运行。
+
+Yaw也不是普通平均。例如：
+
+```text
++179°和-179°
+```
+
+圆周平均会得到接近 `±180°`，而不是错误地得到 `0°`。
+
+## 当前平均真正的问题
+
+它隐含了一个假设：
+
+> 所有成员定位精度相同、可信度相同，而且没有异常值。
+
+对你目前的 Detour 情况，这个假设不够可靠。
+
+假如真实车队中心是0，而：
+
+```text
+车辆1定位正常：0mm
+车辆2发生小范围跳变：+60mm
+```
+
+当前等权平均会得到：
+
+```text
+估计中心：+30mm
+```
+
+如果60mm还没有超过候选差异阈值，这个错误会进入车队中心控制。
+
+当前估计器存在三个主要限制：
+
+- 所有成员等权，没有利用定位质量、数据年龄和历史稳定性；
+- 单个异常成员超过阈值时，会使整个车队状态不可用，不能隔离坏成员；
+- 它是单帧估计，没有利用上一周期车队中心和轮速预测判断哪辆车更可信。
+
+而且你目前主要是双车。两辆车互相矛盾时不存在“多数票”：
+
+```text
+车1说中心在A
+车2说中心在B
+```
+
+只看这两个当前观测，无法判断谁正确。必须引入：
+
+- 上一周期车队状态；
+- 轮速运动预测；
+- 每辆车定位健康状态；
+- 数据新鲜度；
+- 连续多帧确认。
+
+## 更成熟、适合你的方案
+
+我建议采用：
+
+> 带时间预测和异常门控的鲁棒加权 SE(2) 融合。
+
+不需要现在就上复杂的因子图或完整EKF。
+
+### 第一步：保留当前反算方法
+
+继续让每辆车计算：
+
+```text
+候选车队位姿
+= 成员实际世界位姿
+× 成员固定布局位姿的逆
+```
+
+这部分当前是正确的，不需要推翻。
+
+### 第二步：增加上一状态预测
+
+根据上一周期车队中心和轮组速度预测：
+
+```text
+PredictedFleetPose
+```
+
+然后每辆车的候选中心分别与预测值比较：
+
+```text
+位置创新
+航向创新
+```
+
+这样双车出现分歧时，可以判断：
+
+```text
+车1与预测连续
+车2突然跳变
+→ 暂时拒绝车2，而不是两车平均或全队立即失败
+```
+
+### 第三步：成员单独门控
+
+每个成员分别检查：
+
+- 状态是否可用；
+- 数据是否过期；
+- 相对预测的位置创新是否合理；
+- 相对预测的航向创新是否合理；
+- 是否连续多帧异常；
+- 后续是否连续多帧恢复。
+
+不要只做当前这种“成员之间两两比较”。
+
+### 第四步：对通过门控的候选加权融合
+
+权重可以先用简单工程等级：
+
+```text
+健康且新鲜        → 权重1.0
+轻度退化或较旧    → 较低权重
+正在异常确认      → 权重0
+```
+
+以后 Detour 如果能提供协方差，再改成按协方差加权。
+
+对残差使用 Huber 一类鲁棒损失会让正常小误差仍按最小二乘处理，而异常大残差的影响被压低；这是成熟估计库采用的标准做法，[GTSAM官方文档](https://gtsam.org/doxygen/a04439.html)也明确给出了 Huber 在迭代重加权最小二乘中的权重形式。
+
+### 第五步：输出融合健康等级
+
+建议以后区分：
+
+```text
+Healthy
+所有有效成员一致，正常融合
+
+Degraded
+有一个成员被拒绝，暂时依赖剩余成员和预测，整队限速
+
+Unavailable
+所有成员都不可信，或双车分歧且无法判断谁正确
+短时保持轮速预测，随后停车
+```
+
+## 更严格的数学形式
+
+成熟版本可以直接求一个最符合全部刚体观测的车队位姿：
+
+\[
+T_f^*=
+\arg\min_{T_f}
+\left[
+w_p\|\log(T_{pred}^{-1}T_f)\|^2+
+\sum_i w_i\,\rho\left(
+\|\log((T_fT_{layout,i})^{-1}T_{actual,i})\|^2
+\right)
+\right]
+\]
+
+它表示：
+
+- `T_f`：要求解的车队实际中心；
+- `T_layout,i`：第i辆车的固定布局；
+- `T_actual,i`：第i辆车当前测量位姿；
+- `T_pred`：根据历史和轮速得到的预测中心；
+- `w_i`：成员可靠性；
+- `ρ`：Huber等鲁棒损失。
+
+这是“鲁棒刚体拟合”，比单纯平均更完整，同时利用位置和航向。普通最小二乘刚体配准本身就是成熟方法；鲁棒损失是在异常观测下限制单个数据影响的标准扩展。[刚体点集最小二乘原始问题说明](https://ntrl.ntis.gov/NTRL/dashboard/searchResults/titleDetail/PB91135772.xhtml)
+
+如果将来各车能提供可信协方差，但不同SLAM估计之间的相关性未知，可以考虑 Covariance Intersection；它专门处理未知交叉相关性的估计融合。[Julier与Uhlmann的SLAM融合论文](https://www.sciencedirect.com/science/article/abs/pii/S0921889006001436) 但你目前拿不到Detour协方差，所以现在直接上CI没有足够输入。
+
+## 对当前项目的建议
+
+当前先不要推翻 `FleetStateEstimator`。合理的推进顺序是：
+
+1. 保留现有布局反算、时间对齐、圆周Yaw平均和成员误差计算。
+2. 增加“上一车队状态＋轮速”的中心预测。
+3. 把两两一致性检查改成“每成员相对预测的独立门控”。
+4. 对通过门控的成员做加权圆周平均或小规模Huber融合。
+5. 允许单个成员短时降级，不要一帧异常就让整个估计不可用。
+6. 双车无法判断谁正确时，短时间用预测，仍无法恢复再停车。
+7. 最后再考虑完整的SE(2)鲁棒最小二乘，不需要一开始引入GTSAM或QP。
+
+对整个 `MultiWheelC\Fleet` 的当前评价是：
+
+- 布局定义、刚体速度分解、中心控制、相对误差纠偏、最差成员统一减速和全员Ready屏障，结构上没有明显问题；
+- 当前最大算法缺口就是车队中心融合还不够鲁棒；
+- 最大工程缺口仍是运行入口、通信、成员超时看门狗、报警汇总和零速命令的实际下发；
+- `FleetMemberAgent` 目前还缺少独立自动化测试；
+- 各种阈值目前只在测试构造中出现，尚未通过双车实车数据标定。
+
+所以，平均本身不是错误；“只做等权平均，并在冲突时整队不可用”才是需要下一阶段改进的部分。
+
+
+
+
+
+
+将 FleetMemberReport 转成 FleetMemberStateSample 和 FleetMemberSafetyStatus；
+将准备命令映射到 FleetMemberAgent；
+将成员速度命令映射成 FleetCommand；
+ShouldStop 时广播 Stop 并让主车本地停车；
+命令序号、报告序号和任务编号检查；
+M层报警和底盘执行失败映射到 FailureCode；
+无线端口初始化；
+报文序列化、分包、校验和接收循环；
+主车本地单调时钟和报文接收时间记录。
