"""inline 直调路径 与 zenoh 路径 的一致性测试。
|
||
|
||
守护"进程插件 ↔ 内置插件无缝迁移"契约：同一个 worker 副本，分别经
|
||
A) 进程内直调（chongming_worker.dispatch：网关 inline 快路径用的入口）
|
||
B) zenoh 查询（session.get → router → queryable 回调 → 原有路径）
|
||
发起同一批请求，逐字段比对两路结果（仅屏蔽时间戳这类天然不同的字段）。
|
||
|
||
覆盖：正常 GET / POST、模型校验失败（reply_err 通道）、未知 subject、
|
||
非信封旧式载荷、流式多块、流式生成器异常收尾块。
|
||
|
||
运行: uv run python test/test_inline_local_dispatch.py
|
||
（需要 zenoh router 在 config/zenoh_config.json5 指向的端点可达）
