 - 触发条件：有出生分钟的个人盘咨询，模型按旧合同把 `| 技法 | 状态 | 说明 |` 写进 `answer.delta`。
 - 根因：可见语音要求口语末尾贴完整 Markdown 技法审计表；`.markdown-table` 没有样式；列表项里的段落仍吃正文边距。BUG-011 只禁止内部 `EvidenceAuditPanel`，没有另做用户可读的折叠表。
 - 修复：口语不再粘贴审计表。服务端把已交付行放进回执，界面用默认收起的 `本轮技法` 折叠块展示。历史回答若仍带该 Markdown 表，则从正文拆出再折叠。比较表与列表改用对话字号、边距和横向滚动。不恢复内部证据面板、英文状态码或 raw receipt。
