-## 快速上手
-
-### 1. 评测当前模型
-
-```bash
-cml workflow run \
-  --workflow_id f-20260408161444-wu3pz --version v28 \
-  --global_inputs runDic=<N> \
-  --global_inputs model_path_new=<新模型路径> \
-  --global_inputs model_path_old=<基线模型路径>
-```
-
-### 2. SFT 训练（CML 云端）
-
-```bash
-AUTORESEARCH_ROOT=/mnt/wangsenhao/autoresearch-zk \
-  ./scripts/submit_sft_via_cml.sh <RUNDIC> [PREV_RUNDIC]
-```
-
-训练完成后自动起评测 workflow。
-
-### 3. SFT 训练（本地）
-
-```bash
-AUTORESEARCH_ROOT=/mnt/wangsenhao/autoresearch-zk \
-  python scripts/prepare_and_train_sft.py prepare --output_dir ./sft_data
-
-AUTORESEARCH_ROOT=/mnt/wangsenhao/autoresearch-zk \
-  python scripts/prepare_and_train_sft.py train \
-  --data_dir ./sft_data \
-  --model_path /mnt/wangsenhao/verl_zk/Qwen3-4B-Instruct-2507 \
-  --model_type qwen3 \
-  --train_output ./sft_output \
-  --epochs 3 --lr 1e-5
-```
-
-## 关键规则
-
-- **达标标准**：需求集合 ≥ 95%，大盘车载降幅 ≤ 0.3%，specific test 降幅 ≤ 1%
-- **数据清洗**：case 驱动、禁止批量、必须备份、只改 output 不动 instruction
-- **训练环境**：FSDP2 + torch 2.6 需要 accelerate==1.7.0，不要改训练代码去适配

+# 多轮对话连贯性 —— ComplexTask 继承规则
+
+## 核心判定
+
+| 场景 | 输出 | 示例 |
+|------|------|------|
+| 上轮是 ComplexTask + 当前 query 和上轮**相关**（延续/细化/替换/挑选/追加） | 当前仍 `ComplexTask(tag="...")` | 上轮 CT 导航多目的地，当前"第二家导航过去" → CT |
+| 上轮是 Agent + 当前 query 是独立新任务 | 按当前 query 独立分类 | 上轮 Agent 导航，当前"播放周杰伦" → Agent(音乐播放) |
+| 上轮是 ComplexTask + 当前 query 是**无关**新任务 | 按当前独立分类 | 上轮 CT 旅游，当前"今天天气怎么样" → QA/WeatherQA |
+
+## 判定要点
+
+- **"相关"的定义**：当前 query 是对上轮任务的**延续、细化、替换、挑选、追加**中的任一类：
+  - 延续：用户在上轮的同一任务线上继续操作（"继续导航"/"换一条不堵的"）
+  - 细化：对上轮结果加筛选条件（"人少一点的"/"评分最高的"/"最近的那个"）
+  - 替换：换掉上轮的某个要素，同领域保持（"不要 A 换成 B"）
+  - 挑选：从上轮推荐的候选中选择（"第一个"/"第二家"/"刚给的那个"）
+  - 追加：在上轮任务基础上加步骤（"路上再加个加油站"/"顺便找个 ATM"）
+
+- **prev 侧"隐式 CT 信号"（R17777 补充）**：prev 即使只是一轮用户独白，只要含以下任一信号也视作 CT 场景：
+  - **单轮内自我修正/替换**："导航到 A 哦不对 B"、"去 X 啊不 Y"、"到 A 嗯就是 B" —— 用户在说的过程中换目的地，系统需处理替换逻辑
+  - **候选选择犹豫**："是 A 还是 B"、"哪个近就哪个"、"算了不去 A 了"
+  - **多 POI 枚举/对比**："A 和 B 哪个近"、"先说 A 再说 B"
+
+> 注：单 POI + 多重形容词筛选（"最便宜的有车位的充电站"）**不算** CT 信号，按 R1 归 Agent。
+
+- **继承的是 `complex` 维度，不是 tag 内容**：tag 仍可能是 Agent 标签，但 complex=true，因为复合任务语境未结束
+
+## 反例（不适用继承）
+
+- 当前 query 明显切换意图：上轮 CT 导航 → 当前"打开空调"（tag=车载控制，无关）→ 独立分类
+- 当前 query 是独立的闲聊 / 时间 / 天气问答：上轮 CT → 当前"现在几点" → 独立分类
+- 上轮是 CT 但失败/取消（"算了不要了"）：后续 query 不再继承
+
+## 为什么需要这条规则（经验来源）
+
+R17775 迭代中，我们修改了训练集 47 条"纯路线偏好"样本 complex=true → false，对齐 0511 专项 gold（60% → 76.67%）。但这产生副作用：
+
+- `复杂导航线上真实_rag` -3.30pp（11 条 gold=true 被过度修正为 false）
+  - 如 "我要重新选一个路线"、"嗯经过凤雏路去江北虹悦城"
+- `0511 专项` 新引入 6 条错全是**多轮延续 POI/挑选**类
+  - 如 "评分最高的那个导航过去"、"第二家导航过去"、"人少一点的"
+
+根因：单看 query 这些表达像"纯偏好"，但在多轮上下文中是**对上轮 ComplexTask 的挑选/细化**，应继承 CT。SFT 模型在只看当前 query 时判错。
+
+## 应用场景
+
+- **数据增强**：生成带 prev_session 的训练样本时，如果 prev 是 `ComplexTask(...)`，当前 query 与之相关 → ground_truth 必须是 ComplexTask（不能矛盾）
+- **训练集清洗**：不要把"多轮延续同任务"类样本的 complex=true 改为 false（R17774 的 47 条改动里，L10752 / L10943 / L10954 等 multi_turn_deixis 已保留未改，正确）
+- **Badcase 分析**：错例 query 如果语境是对上轮 CT 的延续，SFT 模型判错不能靠修改训练集同 pattern 样本的 label 来解，需要补"带 prev_session 的延续 CT"仿写增强模型学到上下文信号
+- **Reward 函数**：对违反此规则的预测（prev=CT + 相关继续 但 pred complex=false）应被惩罚
+
+## 反模式
+
+- ❌ 只看当前 query 文本判 complex，忽略 prev_session
+- ❌ 训练集批改 complex=true→false 时未检查 prev_session，导致多轮延续样本被误改
+- ❌ 生成仿写时当前 query 与 prev_session 矛盾（prev CT 但 current 标 complex=false）
