- 防复发:任何对启用 RLS 的表新增 runtime grant 时,必须同时测试对应运行时角色的真实可见行,而不能只断言 `has_table_privilege=true`feature flag 种子测试必须以 Web 实际使用的 `admin_runtime` 读取。

## BUG-169 | V9 新建生时校正 Session 未绑定模型导致 Agent 立即返回模型不可用
- 状态:resolved(本地候选)
- 首次发现:2026-08-11
- 最近更新:2026-08-11
- 影响面:V9 `open_agentic_rectification_case` 新建会话、既有 `model_id is null` 的生时校正会话,以及 `POST /api/rectification/agent` 的模型解析。
- 用户现象:运行时开关恢复后,原请求继续返回 `409 模型暂不可用`;请求体包含有效 `modelId`,管理端模型及供应商也均为 published/enabled。
- 触发条件:V9 Open Case RPC 原子创建 `birth_time_rectification` Session 后立即发送 opening。
- 根因:RPC 插入 `chat_sessions` 时没有写入 `model_id`;前端仅在内存中把目录默认模型显示为当前选择,而 Agent 路由按安全合同只解析服务端持久化的 `chatSession.model_id/model_config_version`,不会信任请求体覆盖会话模型。
- 修复:新增向前迁移 `20260811040000_rectification_session_default_model.sql`;数据库触发器为缺少模型的生时校正 Session 绑定当前 published/enabled 默认模型,由既有 pin trigger 固定配置版本,并一次性回填同类历史 Session。普通咨询 Session 与已有明确模型选择均不改变。
- 验证:V9 PostgreSQL fixture 在创建 Case 前播种默认模型,要求 RPC 新建 Session 后持久化为 `v9-default-model:1`;staging 还需核对迁移账本、原 Session 回填结果和真实 opening 请求。
- 防复发:任何服务器端创建 `birth_time_rectification` Session 的路径都必须在同一事务内得到可解析的持久化模型与版本;前端显示的默认模型不能替代数据库绑定。
