"""交付件能力 — pipeline_deliverables 的评审状态机语义化迁移（通用、产线无关）。

定位：交付件 CRUD 走 xls2ui 生成的端点；本模块只做「评审状态流转」——
每个迁移 CAS 原子（防并发/越权）+ 租户隔离 + 审计。

交付件的评审状态机/流转规则在 deliverable 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：pipeline_deliverables 用 project_id 做范围校验（CAS 的 WHERE 里带 project_id）。

注意：评审状态列名是 review_status（非 status）。
