"""测试计划能力 — sd_test_plans 的状态机语义化迁移（通用、产线无关）。

定位：测试计划 CRUD 走 xls2ui 生成的端点；本模块只做「生命周期状态流转」——
每个迁移 CAS 原子（防并发/越权）+ 租户隔离 + 审计。

测试计划的生命周期/流转规则在 test-plan skill 里（LLM 读 skill 判断合法性）；本模块只固化操作原语。

角色规范：role 参数用 agent.{role}（无前缀自动补 agent.）；人角色用 {orgtype}.{role}。

scope 约定：sd_test_plans 无 project_id 列，用 iteration_id 做范围校验（CAS 的 WHERE 里带 iteration_id）。
