## 模型与契约

模型输入为 float32 `obs[batch,N]`,输出为 float32 `actions[batch,M]`,batch 为 1 或动态。
模型结构由 `policy_server.model_type` 或 ONNX metadata `rmcs_model_type` 切换,支持:

- `mlp`:输入可以是 float32 `obs[1,N]`,也可以是带历史帧的 `obs[1,history,feature]`;
- `transformer`:输入为 float32 `obs[1,history,feature]`;
- `generic`:保留 rank-1/2/3 的形状适配,供后续单输入结构接入。

输出支持 rank-1/2/3,只要除 batch 外的元素总数等于动作数 `M`。batch 为 1 或动态。
`auto` 优先读取 `rmcs_model_type`,没有 metadata 时才按 rank-2 推断 MLP、rank-3 推断
Transformer。

多输入模型(例如独立 attention mask 或 position id)除 `obs` 外的输入必须是常量张量,在
`policy_server` 段用 `extra_inputs.<输入名>: [元素列表]` 声明;启动时根据 ONNX 输入类型
创建 `float32`、`int64` 或 `bool` 张量,并校验名字、元素数量和形状;缺声明、类型不匹配
或声明了模型没有的输入都会拒绝;
输出仍必须是唯一的 `actions`。

```yaml
policy_server:
ros__parameters:
extra_inputs:
attn_mask: [true, true, true, true] # bool mask;也支持 int64 position id
```

部署模型须含 `rmcs_obs_layout`、`rmcs_actions_layout`;建议带 `policy_layout_hash` 和版本。
`history_length × 单帧维数 = rl_obs_size`。归一化均值和标准差必须成对提供,标准差为正数。

新模型先核对训练的观测顺序、坐标、基准角、缩放和频率,再盖章:
rank-3 模型的序列切分受强制约束:模型的 `T == v3-history`、`F == rl_obs_size / history_length`,
其中 `v3-history` 来自必需的 `rmcs_obs_layout`,并且最终还会由动作消息的 layout hash 与
`rl_bridge` 再次核对。`rmcs_history_length`、`rmcs_obs_frame_size` 和 `sequence_length` 是
启动时的辅助维度声明,缺失或不一致都会拒绝;它们不能替代布局签名。

修正 README 中辅助维度"缺失即拒绝"的描述。

第 83-84 行写明 rmcs_history_length、rmcs_obs_frame_size 和 sequence_length "缺失或不一致都会拒绝"。代码只拒绝"不一致"的情况,不拒绝"缺失"的情况:

  • src/policy/onnx_runtime.cpp 的 parse_positive 在 metadata 缺失时返回 0。
  • 只要存在 rmcs_obs_layout,序列维度就回退到 layout->history。
  • test/runtime_test.cpp 的 LoadsSequenceUsingRequiredLayoutOnly 也断言缺少这些键时模型可以正常加载。

按当前文档,操作者会以为漏写这些键时启动会失败。实际上启动会成功。

更新 README 中关于 rmcs_history_length、rmcs_obs_frame_size 和 sequence_length

带历史帧的模型示例(桥和策略进程都要使用同一历史长度):

```yaml
rl_bridge:
ros__parameters:
history_length: 8
rl_obs_size: 208 # 8 × 26
policy_server:
ros__parameters:
model_type: "transformer" # 带历史帧 MLP 这里写 "mlp"
sequence_length: 8 # 动态 rank-3 输入时需要
feature_size: 26
rl_obs_size: 208
```

### 模型盖章

部署模型必须含 `rmcs_obs_layout`、`rmcs_actions_layout`,建议同时带 `policy_layout_hash`
和版本。盖章按**当前 YAML** 生成签名,所以顺序是先核对训练布局、再盖章、再同步 YAML、
最后复验。

**1. 装依赖(一次性)**:需要一个带 `onnx` 与 `PyYAML` 的 Python。没有就运行:

```sh
bash src/rmcs_rl/tool/install_model_tools.sh
```

它创建 `/opt/rmcs-tools/venv`;已有环境则 `export RMCS_ONNX_PYTHON=<venv>/bin/python` 直接跳过安装。
`stamp_model.sh` 自己会依次找 `RMCS_ONNX_PYTHON`、该 venv、`python3`;下面直接调用
`python3` 的脚本若系统解释器没装 `onnx`,改用 `<venv>/bin/python`。

**2. 核对训练布局**:逐条确认观测顺序、坐标、基准角、缩放和频率与当前 YAML 一致。
YAML 写错会盖出「自洽但错误」的签名,后续校验照样通过,所以这一步不能省。

**3. 盖章**:推荐用一键脚本。它先提示模型布局与 YAML 是否一致(不一致只警告不阻断),
盖完立即复验,最后打印要手工改的 YAML 两行:

```sh
bash src/rmcs_rl/tool/stamp_model.sh <模型.onnx> --config <车辆配置.yaml> --version <版本>
```

按工具输出同步 `policy_server.rl_model_path`、`rl_bridge.expected_model_id`,然后验证:
模型放在 `src/rmcs_rl/models/` 下时只写文件名;`--config` 缺省为
`src/rmcs_bringup/config/wheel-leg-infantry-rl.yaml`,`--node` 缺省 `rl_bridge`。
带历史帧或特殊结构时补 `--model-type mlp|transformer|generic`、`--sequence-length N`、
`--feature-size N`。脚本只盖 metadata,不改计算图/权重,也不改 YAML——YAML 由你手工改最安全。

只需写 metadata、不自动复验时用底层脚本。盖章默认写入序列键(`rmcs_history_length`/
`rmcs_obs_frame_size`,取自 YAML);部署端还会从必需的 `rmcs_obs_layout` 中读取
`v3-history`,防止只依赖可选 metadata。`rmcs_model_type` 可选,缺省由部署端按输入 rank 推断:

```sh
python3 src/rmcs_rl/tool/stamp_layout_metadata.py \
--model policy.onnx --from-config <车辆配置.yaml> --node rl_bridge \
--model-type transformer
```

**4. 同步 YAML 两处**:按工具输出手工改 `policy_server.rl_model_path` 与
`rl_bridge.expected_model_id`,不要让脚本改配置文件。

**5. 复验**:

```sh
python3 src/rmcs_rl/tool/check_policy_contract.py <模型.onnx> --config <车辆配置.yaml> --node rl_bridge --expect-model-id <ID>
```

**6. 重启 RMCS**:更新模型或配置后必须重启。模型或布局不匹配会锁存拒绝动作,需要重启恢复。

盖章只写元数据;布局匹配不能证明训练侧的坐标或动作含义正确。
更新模型或配置后重启 RMCS。模型或布局不匹配会锁存拒绝动作,需要重启恢复。

当前 `models/deformable_sps_V2.onnx` 缺少 `rmcs_obs_layout` 和 `rmcs_actions_layout`,
完整契约检查与策略服务会拒绝它。这是已有模型的部署缺口,需核对训练契约后补元数据;
不能只按张量维数推断其含义。
当前部署使用 `models/deformable_v2_transformer.onnx`(8 帧历史 × 32 维单帧,输入 rank-3
`obs[1,8,32]`,`rmcs_model_type=transformer`);其 `rmcs_obs_layout`、
`rmcs_actions_layout`、`policy_layout_hash` 和 `policy_version` 已按
`deformable-infantry-omni-rl.yaml` 盖章。盖章只确认运行时布局契约,不能只按张量维数
推断训练侧的坐标或动作含义;更新模型或 YAML 后必须重新盖章并同步 `expected_model_id`。
