"""test_graphctl.py —— 「图模式」自动化测试（2026-10-18）。

## 覆盖二十三类
1 建图（--kpi / --nodes-json）            7 边界（单节点 / 空节点 / gid 含中文 / 图不存在）
2 校验硬错（环 / 悬空依赖 / 状态非法）      8 独立性（只写临时目录，不碰现有机制文件）
3 校验警告（无域 / 无判据 / 域重叠）        9 并发写（两进程同时写不丢状态）
4 就绪集（依赖 / 域冲突 / 并发上限）        10 租约（超时回收三种策略 / 名额释放 / 节点级覆盖）
5 状态流转（pending→running→done）          11 重试与触发规则（三种退避 / 三档 deps_rule）
6 非法操作（重复开工 / 非法 state）          12 动态展开（over / from / N=0 / N 大 / child_domain）
13 条件分支（when / on_dep_fail 三档）       17 按域分池（meta.pools / --pool）
14 子图（内联展开 / 子节点收敛 / 互斥）      18 自动派活（tick / plan 四条硬规则）
15 人审（awaiting / approve / reject）       19 进度与关键路径（progress）
16 取消（连坐子节点 / --all / 下游跳过）
20 验收判据机判（artifact / evidence 两种条目、缺什么报什么、纯文本不拦、人审同样受限）
21 回退边（rework_to 上游校验 / 复位链 / attempts 与事件 / 人审驳回自动回退 / 收回已展开子节点）
22 运行期改图（add-node / remove-edge / 并发加节点不丢更新 / 运行中加节点可被派）
23 跨图子图（subgraph.gid 引用另一张图 / 内部依赖加前缀 / 父等收敛 / 缺图·自引用·跨图环·嵌套全报错）

## 跑法
    python graph/test_graphctl.py -v

## 落点
临时工作区 = `$GRAPH_TEST_TMP`（默认 `AIProject/ai1net-dsh-server/tmp`）/`graph-test-<pid>`/<用例名>，
整体删除；每个用例一个干净工作区，互不影响。
