+## BUG-504 | 开场采集题用「再说一件」措辞，用户不知从何说起
+
+- 状态：resolved
+- 首次发现：2026-09-03
+- 最近更新：2026-09-03
+- 影响面：`spokenFollowupForUser`、`GENERIC_COLLECT_QUESTION`
+- 用户现象：新用户开场招呼后看到「也可以再说一件你记得大概时间的事。」不知道该写什么；招呼段按设计不提问、不举例。
+- 触发条件：零证据开场，`OPENING_COLLECT_DOMAIN = other`，followup `source=method_coverage`。
+- 根因：`e8c98c37` 把开场 domain 改成 `other` 后，`spokenFollowupForUser` 按 domain 查 `USER_COLLECT_QUESTION`。`other` 是给已有证据后的补问兜底（「也可以再说一件」），真正开场文案 `GENERIC_COLLECT_QUESTION` 只在 domain 查不到时才用。domain→文案查表把兜底文案当开场。
+- 修复：`source === method_coverage && domain === other && collect_retry !== true` 时用 `GENERIC_COLLECT_QUESTION`。文案补上「一件事」和「哪年搬的家」。`oos_blind` 兜底与 `collect_retry` 的 `other` 仍用原补问。不改 `OPENING_COLLECT_DOMAIN` / questionId / 记账。
+- 验证：`rectification-server-focus` 零证据开场 spoken prompt 等于 `GENERIC_COLLECT_QUESTION`，不含「也可以再」，含「比如」；exhaustion `oos_blind` 与 `collect_retry` 仍走 `USER_COLLECT_QUESTION.other` / retry。源码锁至少两个具体例子。
+- 防复发：开场题文案必须带具体例子；`USER_COLLECT_QUESTION.other` 只用于已有证据后的补问。
+- 相关记录：BUG-501
