 - Web 技术栈为 TypeScript、React、Tailwind CSS、Next.js Pages Router；不要切换到 App Router。
 - 使用 pnpm 管理 JavaScript workspace，使用 uv 管理 `tools/figures` 的 Python 项目，保留两套锁文件。
 - 文档正文、目录元数据与修订记录以站点现有 SQLite 数据库为唯一权威源，使用文档 API 或 docs 管理工具直接更新；不得把新正文、目录 JSON、数据库文件或日常内容快照提交到仓库。历史 Git 文档只用于显式的一次性迁移，不作为运行时种子。Python 图形源码放在 `tools/figures/src/endor_figures`，可复现的 SVG 输出放在 `apps/docs/public/figures`。
+- 编辑已有文章时优先使用章节 API：先读取章节目录与内部摘要，据此选择需要读取正文的章节，再提交单章或多章操作。摘要缺失时先读对应正文并补充；修改观点前必须核对该章原文，检查读取版本与提交 revision 一致。摘要只写入内部章节数据，不放入网页正文、目录摘要或 Git；改写正文时同步更新摘要。完整操作与 Python 客户端用法见 README 的「先读摘要，再按章节编辑」。
 - 未确认的架构提议明确标注为草案，不能表述为现有实现。
 - 本地开发与预览只监听 `127.0.0.1`。部署容器监听 `0.0.0.0:3000`，服务器入口默认 18135，可通过独立 production.env 配置。
 - 对 gitea.entroia.com 仅使用 codex-bot，提交身份为 Codex Bot <codex-bot@gitea.entroia.local>。SSH 使用隔离配置：`ssh -F /dev/null -o IdentitiesOnly=yes -i /Users/zzyang/.codex/credentials/gitea-entroia/codex_entroia_ed25519 -p 22222`。

 建议写入时提供 `Idempotency-Key`，由 1—128 个字母、数字或 `._:-` 组成。同一个 Key、相同请求 ID 和相同输入重试时，返回原回执并标记 `replayed: true`，不追加修订；相同 ID 改换输入会冲突。回执描述原请求，不代表之后没有其他修改；需要当前内容时重新读取文档。改过正文或 revision 后，应使用新的请求 ID。
 
+### 先读摘要，再按章节编辑
+
+章节接口使用相同的文档 Key 和读写权限。编辑流程为：先读章节目录及摘要，选择需要深入的章节，再读取这些章节的正文，最后提交一组操作。不要只凭摘要修改未读正文；目录与正文响应的 `revision` 应一致，否则重新读取。接口不调用模型生成摘要：由编辑 Agent 阅读正文、撰写摘要，并在编辑请求中保存。
+
+章节按行首 Markdown ATX 二级标题（`##`）划分，三级至六级标题随所属章节一起编辑；代码围栏内的标题不会切章。二级标题之前的文档标题及导言属于固定 ID `preamble`，可以修改但不能删除或移动。Setext 标题、带缩进或引用、列表标记的标题不作为章节边界。正文无行首二级标题时，全文作为导言处理。拆分及组合保持换行和未编辑内容原样，不自动格式化 Markdown。
+
+目录中的每章包含 `id`、`title`、`position`、`summary`、`summaryStatus` 和 `contentHash`。摘要为编辑内部数据，单独保存在 SQLite 的 `document_sections` 和 `document_section_revisions` 中，不加入普通文档响应、网页 props、搜索索引或页面正文。完整数据库备份包含这些表；`docs export` 仍只导出当前文档，不包含内部摘要和修订。
+
+旧文章无需重写，首次读取即可按原文返回目录，初始摘要为空，`summaryStatus` 为 `missing`。Agent 应按需读取这些章节，生成摘要并通过 `update` 保存；保存后状态为 `current`。这里的 `current` 仅表示摘要与该版正文一起保存，不保证模型的总结正确。全文接口仍兼容；未变化章节保留摘要与 ID，正文变化的章节清空摘要，等待更新。全文改名且改写章节时可能产生新 ID，因此全文保存后应重新读取目录。
+
+章节编辑请求示例（示例 ID 需要替换为目录实际返回的值）：
+
+```json
+{
+  "revision": 3,
+  "operations": [
+    {
+      "op": "update",
+      "id": "s_existing",
+      "content": "## 原有章节\n\n修改后的正文。\n\n",
+      "summary": "本章说明修改后的核心观点与边界。"
+    },
+    {
+      "op": "insert",
+      "after": "s_existing",
+      "content": "## 新章节\n\n新增论证。\n\n",
+      "summary": "补充上一章尚未覆盖的论证。"
+    }
+  ]
+}
+```
+
+`update` 可只改 `summary`，也可改正文；正文改变时若不提供新摘要，旧摘要会清空。`insert` 必须提供正文和非空摘要；摘要最多 8000 个 JavaScript 字符单位。`delete` 使用 `{ "op": "delete", "id": "s_existing" }`；`move` 使用 `{ "op": "move", "id": "s_existing", "after": "preamble" }`。按数组顺序执行，最多 100 个操作；新章 ID 由服务器生成，在回执目录中返回。章正文应从自己的 `##` 标题开始，只包含一个二级标题，并保留与下一章之间的换行；跨章代码围栏或章节边界改变会被拒绝，拆章请使用多个操作。
+
+章节变更、内部摘要、组合后的全文和历史快照在同一事务内提交。每批操作只增加一次文章 `revision`；摘要单独更新也增加版本号。后续操作失败或全文版本过期时全部回滚。写入沿用幂等规则，回执包含新版本、章节目录和 `replayed`；章节接口与全文接口的幂等记录分开。修改章节不会改变其 ID，移动亦保留 ID；删除后的正文和摘要仍可从对应的旧修订读取。启用前的历史修订只有原文，摘要显示缺失。
+
+Python 客户端对应命令：
+
+```sh
+python3 scripts/documents-client.py outline endor/endor-purpose-draft
+python3 scripts/documents-client.py sections endor/endor-purpose-draft preamble s_existing
+python3 scripts/documents-client.py edit-sections endor/endor-purpose-draft /private/path/edit.json --request-id chapter-edit-1
+```
+
+`outline` 和 `sections` 支持 `--revision`；请求文件只包含 `revision` 和 `operations`，不要把内部摘要文件提交到 Git。
