+"""⑤.7 配置台 ↔ 内核配置推送契约 —— issue #67 / PRD ⑤.7。
+
+发布（#66）之后的下一步是**把配置真正送进内核**让 edge-gateway / rag-kb /
+model-framework 生效。配置台与内核是两个独立部署单元，二者通过**配置推送契约**
+解耦：配置台把一份已发布版本打包为内核可消费的 **JSON manifest**（带校验和），
+内核侧拉取/接收后先验完整性再加载。本模块实现这个契约的"配置台侧"：
+
+- ``PushManifest``：推送给内核的清单（版本 / 快照 / 校验和 / 生成时间 / 来源）；
+- ``PushChannel``：推送通道。
+  - ``build_manifest(release)``：把 Release 打包成 manifest，计算 SHA256 校验和
+    （对快照做规范 JSON 序列化后哈希，确保内核侧可复算验证）；
+  - ``push(release)``：模拟推送——把 manifest 写到内核预期的接收目录
+    （``<inbox>/manifest-<version>.json``），并记录推送日志（幂等：同版本不重复推送）；
+  - ``pushed_versions()``：已成功推送的版本清单；
+  - ``verify(manifest)``：校验 manifest 的校验和是否一致（内核侧或配置台侧复用）。
+
+幂等性：同一版本重复 push 返回已推送的旧记录（不覆盖、不重复写文件），避免内核
+重复加载；要重推需先 ``retract``（撤回）该版本。
+
+零运行时依赖：仅用 json / hashlib / dataclass / 标准库。
