 ## [Unreleased]
 
+## 🐛 修复
+
+- **dream / sleep 侧那 5 处 prompt 一直没有围栏：巩固把 46K 清单读成「没人给我下指令」，约 43 万 token/天白烧（#501，社区报告 #493 追加）**：#493 修的是「模型把喂进去的会话转录当成自己的发言」，但围栏只装在 `autoSummarize` 那一处——`src/summarize.js` 之外，`dream.js` 的叙述条/巩固/摘要与 `sleep.js` 的冲突裁决/模式提炼这 5 处一直是把清单**裸放**在 user 消息里，system 之后没有任何分隔与角色约束。现场：`dream_consolidate` 9 次失败、输入 47K→55K tokens 而输出只有 212–907 tokens，日志里模型说「收到——这是一包记忆检索结果，但没有带具体指令，我先过一遍给你一份导览」，于是开始寒暄；报告者的对照实验同时说明方向是对的——只加 system 约束那一臂从 2/2 掉到 0/1，围栏 + 角色重申那一臂仍 1/1。修法：① `lang.js` 新增**记忆清单专用**的成对围栏与角色声明，不复用「会话转录」那对名字（喂的是清单，标错名字会让读审计与读日志的人以为这次喂进去的是一段对话）；角色声明落在 **user 段开头**——#493 实测判断「这段文本是什么」的依据是它所在的那条 user 消息，只写 system 救不回来。② `fenceListBody()` 是纯函数（同一批记忆在下次阈值到来时会被原样再喂一次，重试收到的 prompt 必须与首次逐字节相同，否则「同输入同错」这条诊断依据就没了），并把正文里的 `<<<`/`>>>` 用零宽空格断链——**只中和标记、不删内容**：不然一条写着「<<<记忆清单结束>>>」的记忆就能提前闭合围栏，把后面的文字升格成指令，而记忆正文本来就是模型的可影响输入。③ 失败行的审计 `metadata` 不再为 null：`runAuditedLlm` / `auditedSleepLlm` 加 `spec.metadataFrom(result)`，dream 侧写 `parse_failure` / `raw_len` / `raw_head` / `raw_has_bracket`（`raw_has_bracket` 是区分「压根没按格式写」与「格式对但内容救不回来」的最低成本判据；报告者另指的 `raw_tail` 缺口属 #502）。审计完全复用 dream 既有那条缝，只往导出列表加名字，不重写第三份 chunk 适配。④ 顺带修掉一处**测试侧的脆弱**：多个 mock 靠「user 段以 `id=` / `候选冲突` 开头」认阶段，围栏让首行变成角色声明；改用清单形状（`| type=`）与 `options.purpose`。这不是迁就测试——`dream-candidate-hybrid.test.js` 早就注释说过前缀判据在语义预分组下会把巩固误判成摘要、只能绕开共用 mock，现在那个绕法不再需要。回归锁 5 条（围栏结构、确定性、提前闭合、consolidate 实测带围栏且失败行有读数、5 处不许再裸放的形状锁），变异自证三条（摘掉中和 → 只有提前闭合那条红；摘掉 `metadataFrom` → 只有审计那条红；拆开 consolidate 的围栏 → 审计与形状锁两条红）。评审补的两处：① `fenceListBody` 带输出契约参数——总览摘要要的是散文，对它说「只输出 JSON 数组」会让模型回 `[]`，而 `summaryText.trim()` 判非空通过，方括号就这么被存成库内总览（Major；散文契约用独立的角色声明，叙述条保留 JSON 那份，它的 system 确实要严格数组）；② 流以错误结束、根本没有正文时不再写 `parse_failure` 与 `raw_len: 0`，否则一次限流会被读成「模型没按格式写」。两处各自做过变异自证。
