+| ID | 标签 | 部署用途 |
+|---:|---|---|
+| 0 | `label` | 上游 checkpoint 中含义不清的通用类别；当前 Pipeline 不选择 |
+| 1 | `talking on phone` | 电话使用行为告警 |
+
+`label` 不是背景类，不能从注册信息中删除，否则类别编号会错位并导致模型加载失败。
+生产配置通过 `detect_labels: [talking on phone]` 只请求 class 1。
+
+## 输入与运行参数
+
+- 输入必须是已经解码的 `BGR8` 或 `RGB8` 三通道图像；
+- checkpoint 训练参数记录的 `imgsz` 为 `640`；
+- 当前 CPU 部署从 `max_fps: 5`、`confidence: 0.50` 开始；
+- 该权重由带 `dill` 的环境序列化，项目的 `yolo`/`yolo-cpu` extra 已显式包含
+  `dill`，不能依赖 Ultralytics 运行时临时联网安装；
+- `.pt` 由 PyTorch pickle loader 读取，只应部署经过校验的可信制品。
+
+配置示例：
+
+```yaml
+phone_detector:
+  uses: detection.model@1
+  with:
+    model: people-talking-yolov8x@1
+    detect_labels:
+      - talking on phone
+    confidence: 0.50
+    max_fps: 5
+    attach_frame: true
+    model_options:
+      weights: models/detection/people-talking-yolov8x/v1/best.pt
+      device: cpu
+      imgsz: 640
+      iou: 0.70
+      half: false
+      max_det: 100
+```
+
+## 来源与许可
+
+- 上游项目：[`Anidipta/People-Talking`](https://github.com/Anidipta/People-Talking)；
+- 上游仓库根 `LICENSE` 标记为 Apache-2.0，但 README 的许可段落写为 MIT；
+- 上游没有在模型卡中单独说明训练数据和权重的再分发许可。
+
+因此在外部发布或商业部署前，需要进一步确认代码、权重和训练数据各自的授权范围，
+不能把仓库 README 的一句许可描述直接当成全部资产的授权结论。仓库中的 `.pt` 作为
+普通 Git blob 保存，克隆后会直接获得完整权重。
+
+## 限制
+
+- 这是视觉行为检测，不读取手机屏幕、通话音频或运营商状态；它不能判断来电/去电、
+  是否真正接通，也不能区分普通手持手机与真实通话的全部边界情况；
+- 上游只提供曲线图片，未给出可复核的逐类 AP/precision/recall 数值；当前没有把
+  未知测试集上的指标写成部署承诺；
+- 手部和手机被遮挡、远距离小目标、侧后视角、弱光以及相似手势都可能导致漏检或误检；
+- 当前 adapter 是逐帧检测，不跟踪具体人员。`repeat_gate` 的 `scope: source` 只能表示
+  同一相机连续命中，不能证明连续命中来自同一个人；
+- YOLOv8x 在 CPU 上较重，必须在目标设备测量推理延迟、内存和实际 FPS 后再调高
+  `max_fps`。
+
+## 验证
+
+从仓库根目录执行：
+
+```bash
+sha256sum models/detection/people-talking-yolov8x/v1/best.pt
+uv run --no-sync cmvr-edge-ai models
+uv run --no-sync cmvr-edge-ai validate \
+  --config configs/edge_ai.yaml \
+  --pipeline detection
+```
+
+`validate` 只检查配置和 DAG，不加载权重。发布前还必须执行真实模型加载和单帧推理
+smoke test，确认日志或测试结果中模型 ID、标签顺序和推理输出均正确。
