seq_layout_mismatch.onnx没有覆盖它要验证的路径。
layout_mismatch_meta基于ok_meta构造，所以保留了rmcs_history_length="2"。OnnxRuntime加载时，第 204-205 行先比较rmcs_history_length与rmcs_obs_layout，并在这里抛出异常。执行流程到不了"布局 history 与张量 T 比较"这一步。文档声明该夹具"校验不依赖可选 metadata 的布局签名拒绝"。如果有人删除布局与张量的 T 校验，
RejectsSequenceLayoutHistoryMismatch仍会通过。建议去掉该夹具中的
rmcs_history_length。修改后，test/test_layout_contract.sh第 304 行期望的消息需要改为model sequence dim == expected history。♻️ 建议修改

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。

恢复 expected_model_id 校验。当前没有任何环节核对模型身份。
本次变更删除了 RlBridge::check_contract_ 中对 expected_model_id 的比较。load_bridge_config 也不再读取该参数。相关链路如下：
src/policy/policy_model.cpp第 69 行忽略model_id_of_file的错误。- 对未盖章的模型，
info_.layout_hash为 0。 src/policy_server.cpp第 136 行因此跳过 hash 比较。src/policy_server.cpp第 159 行把message->layout_hash原样写回动作消息。- 回到 bridge 后，
snapshot.layout_hash == layout_hash_恒成立。
结果是：rmcs_rl/rl_bridge 中 rl_model_path 指错，或部署了未盖章的错误模型时，契约门控不会拒绝。该模型的动作会直接驱动电机。
README 第 142-151 行仍要求同步 rl_bridge.expected_model_id，并声明"模型或布局不匹配会锁存拒绝动作"。实际行为与文档不符。
如果"允许未盖章部署"是有意为之，expected_model_id 仍应作为独立的身份门控保留。
