# pytest-asyncio 1.x 要求显式 loop scope；B-74 修复（2026-11-09）：
# session 级 autouse async fixture（conftest._init_checkpointer_global）需
# session/auto 默认 loop scope 方能初始化 checkpointer 并无缝复用于全部测试。

# B-117 修复：仅设 fixture loop scope 不够；测试函数本身默认 function scope，
# 与 session-scoped checkpointer 跨 loop，触发 "Lock bound to different event loop"。
# 将测试 loop 也提升到 session，让所有 async 测试共享同一事件循环，避免 AsyncSqliteSaver
# 内部 Condition/Lock 绑定失效。
