"""ask_clarification 工具参数的共享解析（Harness + Gateway）。
|
||
|
||
圆桌 Step 1（``intent.py``）与 Step 2 总控（``multi_agent.py``）在 SSE 终态帧里
|
||
都会带上 ``allow_multiple``，供前端 ``resolveAllowMultiple`` 决定选项卡片是
|
||
「点击即发送（单选）」还是「多选 + 发送按钮」。
|
||
|
||
约定（与前端 ``roundtable-planning/lib/clarification.ts`` 一致）：
|
||
- 模型**未传** ``allow_multiple`` 或传 ``null`` → **False**（单选）；
|
||
- 仅当模型显式传 ``true`` 时才多选；
|
||
- 不再根据 ``clarification_type`` 推断多选（旧逻辑已移除）。
