 - 验证：工作流契约测试锁定 staging-ref dispatch、源 gate run 证明、无 main 引用、当前 HEAD 防陈旧发布、同一 gate artifact 的 controller/digest 校验和回滚祖先限制；远端 gate/deploy 与运行时 SHA 待本次 staging 发布记录。
 - 防复发：测试环境的部署控制器必须来自被同一 quality gate 证明的 staging SHA；staging gate 名称不得恢复为默认 main 遗留监听器匹配的 `Staging Backend Quality Gate`，也不得重新引入 `workflow_run` 默认分支控制器或 staging/main 相等门禁。production 继续保持独立的 main/staging 收敛要求。

+## BUG-179 | 生时校正候选未显示卡片且回复被推荐问题与内部执行叙述干扰
+
+- 状态：resolved（代码已验证，staging 部署与真实环境验收待发布流程）
+- 首次发现：2026-08-13
+- 最近更新：2026-08-13
+- 影响面：V9 生时校正候选结果展示、对话输入区、Agent 回复自然度与候选采用后的会话延续。
+- 用户现象：服务器已有候选快照时，候选时间仍被写进 Agent 正文而没有出现既有候选卡；输入框下方固定出现三条推荐问题；Agent 还会叙述读取 Skill、加载 Case、调用工具和读取诊断等内部步骤。用户采用候选或表示没有更多事件后，回复容易被迫继续追问或引导结束、暂停、保存进度。
+- 触发条件：Case API 返回已解析为公开 camelCase 字段的 `latest_result`，同时生时校正复用通用 Agent 回复解析器及其三条建议兜底，并且 Prompt/Skill 未明确零问题回复、静默工具执行和无更多事件的停止边界。
+- 根因：候选组件仍按数据库 snake_case 字段读取 Case API 的公开 camelCase 快照，因缺少 `result_id` 判定而丢弃结果；通用 `parseAgentReply()` 在模型未提供恰好三条建议时自动生成三条兜底建议，生时校正又持有并渲染 `composer-suggestions`；Prompt/Skill 只限制“最多一个问题”，未明确完整回复可以零问题、内部执行不得进入正文、用户没有更多事件时不得继续轮换领域，也未划清候选卡与 Agent 正文的内容所有权。
+- 修复：新增客户端候选快照解析模块，按 Case API camelCase 外层字段读取结果并规范化候选内部字段；候选卡独占时间、排名、相对支持度、采用动作和选中状态，近乎并列且未开放确认门时不标记“当前推荐”；生时校正改用只提取正文与标题的解析入口，移除建议状态、持久化和 `composer-suggestions`；Prompt、Skill 与会话策略明确工具静默、零或一个问题、没有更多事件时停止领域轮换、采用后不强制追问或关闭，Session 依现有机制自然保留。
+- 验证：候选解析、回复解析、V9 入口静态合同与 V9 合同聚焦测试共 48 项通过；V9 Agent 聚焦测试 14 项通过；目标 ESLint 与变更源文件定向 TypeScript 检查通过，`git diff --check` 通过。仓库全量 TypeScript 仍命中既有的无关测试类型错误，未在本修复中扩展处理。
+- 防复发：Case API 的公开 DTO 必须有单一解析边界并由合同测试锁定；特殊业务流不得继承通用推荐问题兜底；Agent 正文、Activity 和结构化业务卡片必须各自拥有唯一内容职责，不得重复呈现或把内部执行过程写进自然回复。
+- 相关记录：BUG-173、BUG-174、BUG-175、BUG-176
+- 修复版本：本次提交（staging 精确 SHA 以推送结果为准；尚未部署）
