-// Agent documentation mirrors the canonical Studio guide.
-export const designDocs="# Studio 排版 API · 标准图文与 27 套固定构图\n\n把本篇与图片生成文档一起交给 coding agent。agent 自行选择图片、配色、字体、构图与参数，通过 HTTP 保存渲染描述，得到可持续更新的原生 HTML/CSS 页面。数据库只保存模板关联、文字、素材引用和渲染参数，不保存截图或任意 HTML。\n\n[可选：查看模板示例](/studio) · [读取实时 API 契约](/api/studio/designs?agent_mode=True) · [照片入皮影](/explore/3c98946754c33309d73d5284) · [街头小人](/explore/4ce3283fd98bb03a8fb39a19)\n\n## agent 的交付流程\n\n1. 按下文读取模板 API，选择 layoutId，并获取该模板实际的 T/I/D 元素 ID。\n2. 上传图片取得 assetId，把图片、文字和参数提交给创建 API。\n3. 从创建响应读取 `design.id` 与 `design.url`，把完整结果链接交给用户，例如 `http://8.211.154.134:18131/studio/template-layout?id=实际返回的UUID`。\n4. 用户直接打开该链接看结果；修改内容继续调用 PATCH，同一 ID 与结果链接保持不变。\n\n不要编造 ID，也不要把模板预览链接当作最终结果。API 保存成功并返回真实 UUID 才算完成。以下文档足以通过 HTTP 完成流程，无需使用编辑器。\n\n## 两类排版，同一内容模型\n\n- **标准排版**：`standard-01`，120×160 单位。沿用原 Studio 图文页的标题、正文、栏目结构，增加主题图片与分隔线。T01 主标题、T02 正文、T03 栏目、I01 图片、D01 分隔线。所有内容和位置可设置，也能增加原生元素。\n- **固定排版**：`ref-01` 至 `ref-27`，保留各自画板、出血、圆形、斜切、竖题和字体构图。先读取模板，按实际 T/I/D ID 填入内容。不能假定各模板拥有相同元素。\n\n两类都使用 `/api/studio/designs` 的真实 CRUD。创建额外指定 layoutId；更新从 URL 确定 ID，模板关联不能修改。更换模板应创建新记录，避免把旧元素 ID 错套到新模板。调用方无需打开 `/studio` 或操作编辑器。模板由 agent 经 API 选择，图片和文字由 API 保存，用户只打开结果链接。现有独立工具箱功能保持可用。\n\n## 1. 由 agent 通过 API 发现模板\n\n以下 curl 使用指定服务器。`PROMPT_TOKEN` 由用户通过现有登录方式提供，只保存在进程环境，不放 URL 或日志。也可使用已登录浏览器的同源 Cookie；浏览器写请求需要同源 Origin。未登录 API 返回 401。\n\n```sh\nBASE=http://8.211.154.134:18131\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/studio/api/layouts\"\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/studio/api/layouts/standard-01\"\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/studio/api/layouts/ref-17\"\n```\n\n目录返回 `version, layouts, saveApi, catalogUrl, documentationUrl`。每项包含 `id,name,family,url,api`，family 为 standard/fixed。模板返回尺寸、元素 ID/类型/role/box/direction/text、默认 parameters、workspaceSchema 与页面 URL。`?agent_mode=True` 返回纯文本文档，业务请求移除此参数。\n\n## 2. 生成图片，上传一次，显示压缩衍生图\n\n先让 coding agent 按生成图片文档产出文件；Studio 不暗中调用生成模型。图片可以来自用户素材或生成结果。上传走现有素材 API：\n\n```sh\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \\\n  -F kind=image -F assetOnly=true -F files=@hero.png \"$BASE/api/upload\"\n```\n\n返回 `assets` UUID 数组及对应 `files` 元数据。取 `assets[0]` 作为 assetId。上传不单独发帖；设计创建时才自动关联 Wiki post。不要把 Base64、任意远程 URL、HTML 或 SVG 塞入参数。\n\n原素材保留在素材库，**页面展示只请求压缩 WebP**。以 assetId 引用素材，不必自行再上传缩略图：\n\n```sh\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \\\n  \"$BASE/api/preview?source=%2Fapi%2Fmedia%2FASSET_UUID&width=960\" -o hero-preview.webp\n```\n\nwidth 只允许 240/480/960/1280；小图预算 100KB，大图预算 220KB，复杂图片会降低尺寸/质量。原生页面按槽位显示宽度和像素密度选择 srcset 衍生图，保留 fit/cropX/cropY/zoom。目录使用原生文字与 CSS 色块，不加载参考原图；旧工具箱参考图也使用压缩预览。`/api/media/{id}` 是素材原件读取接口，不应用作展示图片的 src。\n\n## 3. 创建：POST /api/studio/designs\n\n创建和更新共用内容字段 `name,parameters`；`schemaVersion` 可省略，当前仅支持 1。创建额外传 `layoutId`，不传 revision 或 id。\n\n```sh\ncurl -fsS -X POST \"$BASE/api/studio/designs\" \\\n  -H \"Authorization: Bearer $PROMPT_TOKEN\" -H 'Content-Type: application/json' \\\n  -d '{\"schemaVersion\":1,\"layoutId\":\"standard-01\",\"name\":\"观察日常\",\"parameters\":{\"paper\":\"#edf0ef\",\"texts\":{\"T01\":{\"value\":\"观察日常\\n记录灵感\",\"fontFamily\":\"serif\",\"color\":\"#23424b\"},\"T02\":{\"value\":\"让每一页只讲一件事。\",\"lineHeight\":1.4}},\"images\":{\"I01\":{\"color\":\"#73929a\",\"fit\":\"cover\",\"cropX\":50,\"cropY\":45,\"zoom\":1}},\"decorations\":{\"D01\":{\"color\":\"#73929a\"}}}}'\n```\n\n有图片时在 I01 加 `assetId:\"上传返回的UUID\"`。固定排版只需改为所选 `layoutId`，并按 schema 选择元素 ID。例如 ref-01 支持 `texts.T01`、`texts.T02` 与 `images.I01`。\n\n201 返回 `{design}`。design 包含：\n\n| 字段 | 含义 |\n| --- | --- |\n| id / layoutId / family | 持久化 UUID、不可变模板 ID、standard 或 fixed |\n| schemaVersion / revision | 参数契约版本（1）、记录修订号（从1递增） |\n| name / parameters | 名称与规范化内容；省略的分组返回空对象 |\n| url / renderUrl | 同一个原生 HTML/CSS 页面 URL |\n| schemaUrl | 当前模板参数地址 |\n| postId / postUrl | 自动创建并在后续更新中复用的 Wiki post |\n| archived / archivedAt | 可恢复归档状态与时间 |\n| createdAt / updatedAt | 创建与最后修改时间 |\n| legacySvgUrl | 固定排版的旧 SVG 导出地址，标准排版为 null |\n\n创建设计与 Wiki post 在同一数据库事务内完成，失败整体回滚。更新同一设计复用同一 post；手工编辑过的 Wiki 正文、标题、标签、封面不会被参数更新覆盖。\n\n## 4. 读取与打开\n\n```sh\nID=创建返回的UUID\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/api/studio/designs/$ID\"\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/api/studio/designs?layoutId=standard-01&limit=20\"\n```\n\n读取返回 `{design}`，没有副作用。列表默认只列未归档记录；`archived=true` 只列归档记录；limit 为1–50，默认20；`nextCursor` 作为下一页 before。layoutId 可省略。\n\n直接打开创建响应中的 `design.url`：`/studio/template-layout?id={UUID}`。这个 UUID 对应数据库里 API 保存的模板、图片与文字，服务端按记录渲染最终 HTML/CSS。链接中无需携带 layoutId，无需打开 `/studio` 选择模板，也没有编辑按钮、双击编辑或右键编辑。`standard-01` 与 `ref-17` 是模板 ID，不是保存记录的 UUID。\n\n`/studio/designs/{UUID}` 与旧 `/studio/layouts/{layoutId}?id={UUID}` 兼容跳转到同一个结果页。缺失、非法、不存在或已归档的 ID 返回404，不会显示空模板或编辑器；旧链接模板与记录不匹配也返回404。归档设计仍能经 API 读取以恢复。\n\n## 5. 更新：PATCH /api/studio/designs/{id}\n\n先 GET，保留所有未改字段，再整体替换

并合并后再提交；不要盲目重试。不接受 layoutId、id、url、postId 等返回字段；不能直接把整个 design 作为 body。另存副本使用 POST 创建新 UUID。\n\n## 6. 删除与恢复\n\nDELETE 采用可恢复归档，不物理删除参数、素材或 Wiki post。和更新一样必须提供最新 revision；自动同步关联 post 的归档状态。\n\n```sh\ncurl -fsS -X DELETE \"$BASE/api/studio/designs/$ID\" \\\n  -H \"Authorization: Bearer $PROMPT_TOKEN\" -H 'Content-Type: application/json' -d '{\"revision\":2}'\n# 删除后读取新

format=svg、POST 仍提供旧分层 SVG；POST format=json 只验证和返回规范化参数。**旧 SVG 不反映 added、layers、扩展字体和裁切参数**，不能用来证明原生效果。standard-01 不支持 SVG。原生页面应直接打开返回 URL，或用浏览器打印。代码可扩展渲染能力，但每次是否使用、选择哪些参数均由 coding agent 决定。\n\n## 固定排版索引\n\n读取 /studio/api/layouts 获取全部27套构图。\n";
+// Generated from content/studio-tools/layouts-api.md; keep the canonical Wiki guide identical.
+export const designDocs="# Studio 排版 API · 标准图文与 27 套固定构图\n\n把本篇与图片生成文档一起交给 coding agent。agent 自行选择图片、配色、字体、构图与参数，通过 HTTP 保存渲染描述，得到可持续更新的原生 HTML/CSS 页面。数据库只保存模板关联、文字、素材引用和渲染参数，不保存截图或任意 HTML。\n\n[可选：查看模板示例](/studio) · [读取实时 API 契约](/api/studio/designs?agent_mode=True) · [照片入皮影](/explore/3c98946754c33309d73d5284) · [街头小人](/explore/4ce3283fd98bb03a8fb39a19)\n\n## agent 的交付流程\n\n1. 按下文读取模板 API，选择 layoutId，并获取该模板实际的 T/I/D 元素 ID。\n2. 上传图片取得 assetId，把图片、文字和参数提交给创建 API。\n3. 从创建响应读取 `design.id` 与 `design.url`，把完整结果链接交给用户，例如 `http://8.211.154.134:18131/studio/template-layout?id=实际返回的UUID`。\n4. 用户直接打开该链接看结果；修改内容继续调用 PATCH，同一 ID 与结果链接保持不变。\n\n不要编造 ID，也不要把模板预览链接当作最终结果。API 保存成功并返回真实 UUID 才算完成。以下文档足以通过 HTTP 完成流程，无需使用编辑器。\n\n## 多页作品：从创作 brief 到可发布文件（schemaVersion 2）\n\n多页作品由 coding agent 完成创作决策与图像生成，网站负责封闭参数验证、事务保存与原生渲染。无需模型服务、模型密钥或编辑器。先形成主题、读者、意图、逐页分镜，再生成需要的图片，最后通过 HTTP 保存整组作品。封面、正文、结尾共用一个真实 UUID、修订号和 Wiki post。\n\n### 完整内容与视觉模型\n\n创建 `POST /api/studio/series`，body 为 `{schemaVersion:2,name,document}`。读取/整体修订使用 `GET/PATCH /api/studio/series/{id}`；PATCH 额外提供最新 revision。最大512KB，未知字段会拒绝。document：\n\n- `version:1`：多页文档结构版本。\n- `brief`：topic、audience、intent、designIntent、imageStrategy，均为必填非空文字，最多2000字符。分别说明主题、读者、内容目标、完整设计描述和配图策略。\n- `style.version`：agent 指定的样式版本标识（最多80字符），如 `autumn-journal/1`。它用于记录创作版本；不锁定未来网站渲染器，精确交付请同时保留导出文件和 manifest。\n- `style.palette`：paper、ink、muted、accent，均为 #RRGGBB。\n- `style.typography`：title、body、caption 三种层级，每项包含 fontFamily（sans/serif/mono）、fontSize（0.1–40）、fontWeight（100–900）、lineHeight（0.5–4）、letterSpacing（-5–10）。字号和字距以120宽参考画板为单位，固定模板按画板宽度同比换算。\n- `style.spacing`：margin（4–16）、gap（1–10），并要求 `2*margin+4*gap<=48`。标准排版据此计算标题、图片、正文和分隔线的位置；固定模板保留原构图，用 layers 显式调整位置。\n- `sources`：最多100项，每项 assetId、author、license、url、prompt、tool 全部必填，文字最多4000字符。url 是 http(s) 来源地址或 `generated`。用户照片记录来源与授权；生成图记录完整提示词和工具，不把 AI 图写成摄影原作。所有被页面引用的图片必须有来源记录。\n- `pages`：本工作流支持3–18页（这是本服务的约束，不宣称是平台实时上限）。每页 key 唯一（小写字母/数字/连字符，最多60位）、role（首项 cover，中间 body，末项 ending）、layoutId、intent（最多1000字符）、bindings、parameters。parameters 继续使用下文封闭的单页参数契约。\n- `pages[].bindings`：把实际文字元素 ID 映射到 title/body/caption，例如 `{T01:\"title\",T02:\"body\",T03:\"caption\"}`。被绑定元素必须提供文案。共享字体、墨色和纸色会参与真实渲染；单元素显式值优先覆盖。所有可见文字必须提供或明确隐藏，避免默认占位文案泄漏。图片默认色与装饰默认色取 accent。\n\n标准排版可直接沿用 T01/T02/T03/I01/D01；固定排版先读对应模板 API，元素不能混用。agent 必须控制标题长度和正文密度，不能把“已保存”当成“已验收”。同组图片建议统一比例；导出器遇到混合比例会拒绝，agent 应改用同一画板并调整内容布局。\n\n### 一次保存，一条直接结果链接\n\n```sh\n# series.json 包含完整 document，示例文件见仓库 content/studio-examples/autumn-journal.json\ncurl -fsS -X POST \"$BASE/api/studio/series\" \\\n -H \"Authorization: Bearer $PROMPT_TOKEN\" -H 'Content-Type: application/json' \\\n --data-binary @series.json\n# 返回 {design}：schemaVersion=2、document、id、revision、url、postId 等\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/api/studio/series/$ID\"\n```\n\n创建响应的 `design.url` 仍是 `/studio/template-layout?id={UUID}`；直接展示全部页，无需选模板。`&page=2` 只显示第2页，非法页码返回404。页面是服务端原生文字与 CSS，图片走 /api/preview。创建与全部页验证、Wiki post 处于同一事务，任一页无效整组不保存。PATCH 整体替换 document，revision 冲突返回409；先重新读取并合并。单页 PATCH 接口会拒绝修改多页作品，避免只改封面导致组内不一致。可从 designs 列表发现作品，schemaVersion 区分1与2。\n\n归档 `DELETE /api/studio/series/{id}` body `{revision}`；恢复 `POST` 同一路径 body `{revision,archived:false}`。归档后结果页和导出计划返回404，API 仍能读取并恢复；参数、素材和 Wiki post 保留。更新复用原 Wiki post，手工编辑过的正文不被覆盖。\n\n### 高质量导出与验收\n\n`GET /api/studio/series/{id}/export` 返回固定顺序的导出计划：id、revision、每页 key/role/number、filename、width/height、原生渲染 url。计划本身不生成位图。示例统一为3:4、1080×1440 PNG；其他固定模板保留自己的画板比例，不拉伸。该尺寸是本流程的交付规格；发布前还须在小红书当前发布界面复核裁切及文件限制，本站不自动发布。\n\n导出 URL 带 `&page=N&export=1`，画布在1080 CSS像素下重新布局原生文字，不把860宽或手机截图放大。图片使用 `/api/preview?source=...&width=2160&profile=export`：WebP质量95，不为常规缩略图预算降低尺寸，不放大小原件。普通展示仍使用240/480/960/1280及100KB/220KB预算。\n\n在用户已确认的 **ces-control / aliyun-ces-control** 上运行仓库 `scripts/export-studio-series.cjs`，使用既有测试镜像的 playwright-core、sharp、Chromium 和中文字体。只访问 `http://8.211.154.134:18131`，认证保留进程内。设置 STUDIO_DESIGN_ID、STUDIO_EXPORT_DIR、AUTH_CONFIG_FILE（或由现有登录方式提供的 PROMPT_TOKEN），不在命令行或文件中存令牌。不得在用户本机启动编译、容器构建或预览服务器。\n\n脚本逐页检查字体和图片加载、文字溢出、图片原生分辨率与裁切缩放、相同画板比例、页序、最终PNG像素、导出前后revision一致；记录实际字体、SHA256及manifest。额外生成桌面1200宽和手机390宽整组截图供视觉检查。自动检查通过后，agent 仍须逐页看PNG，核对中文缺字、主体裁切、阅读顺序、留白和系列一致性。检查失败修订 document，重新导出；不能把失败文件当成可发布结果。\n\n最终交付：真实设计结果链接、按01/02/03排序的PNG、完整design.json、manifest.json、素材来源与提示词、简短发布文案。生成图、保存成功、导出成功、人工视觉通过、PR待合并、线上部署验收应分别如实报告。未合并代码的能力不可写成线上已可用。\n\n### 可复现三页示例\n\n仓库 `content/studio-examples/autumn-journal.json` 是完整的三页内容与样式文档：封面“把秋天装进一页”、正文“先看见再记录”、结尾“留一点白给下一次”。它不含虚构素材 UUID，空图片位仅用于契约测试。真实制作时先生成银杏母图，再上传取得assetId，在每页 I01 加入该 UUID，并在 sources 记录完整来源。不要把无图夹具当作已完成作品。\n\n推荐在 ces-control 的仓库目录直接执行 `bash scripts/deliver-studio-series.sh /absolute/path/series.json /absolute/path/ginkgo-master.png /absolute/path/provenance.json /absolute/path/output-directory`：该脚本复用已部署认证卷和匹配的CI镜像，依次保存、导出并留下证据，不启动构建或部署。成品位于 output-directory/revision-N/；已成功导出的修订会核对哈希后复用，后续修订使用新目录，避免覆盖或混入旧页。\n\n底层保存命令 `node /app/auth-cli.cjs run /delivery/scripts/save-studio-series.mjs /absolute/path/series.json /absolute/path/ginkgo-master.png /absolute/path/provenance.json /absolute/path/output-directory` 经既有 auth-cli run 在远程执行，上传素材并填写所有页面引用后，保存真实作品，写出请求、响应和状态文件。重复运行会读取已保存状态，防止在成功后重复创建；出现网络结果不明时先核对素材/设计列表，不盲目重试。脚本仅在传入文件后写入作品，不自动发布到小红书。\n\n\n## 两类排版，同一内容模型\n\n- **标准排版**：`standard-01`，120×160 单位。沿用原 Studio 图文页的标题、正文、栏目结构，增加主题图片与分隔线。T01 主标题、T02 正文、T03 栏目、I01 图片、D01 分隔线。所有内容和位置可设置，也能增加原生元素。\n- **固定排版**：`ref-01` 至 `ref-27`，保留各自画板、出血、圆形、斜切、竖题和字体构图。先读取模板，按实际 T/I/D ID 填入内容。不能假定各模板拥有相同元素。\n\n两类单页都使用 `/api/studio/designs` 的真实 CRUD。创建额外指定 layoutId；更新从 URL 确定 ID，模板关联不能修改。更换模板应创建新记录，避免把旧元素 ID 错套到新模板。调用方无需打开 `/studio` 或操作编辑器。模板由 agent 经 API 选择，图片和文字由 API 保存，用户只打开结果链接。现有独立工具箱功能保持可用。\n\n## 1. 由 agent 通过 API 发现模板\n\n以下 curl 使用指定服务器。`PROMPT_TOKEN` 由用户通过现有登录方式提供，只保存在进程环境，不放 URL 或日志。也可使用已登录浏览器的同源 Cookie；浏览器写请求需要同源 Origin。未登录 API 返回 401。\n\n```sh\nBASE=http://8.211.154.134:18131\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/studio/api/layouts\"\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/studio/api/layouts/standard-01\"\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/studio/api/layouts/ref-17\"\n```\n\n目录返回 `version, layouts, saveApi, catalogUrl, documentationUrl`。每项包含 `id,name,family,url,api`，family 为 standard/fixed。模板返回尺寸、元素 ID/类型/role/box/direction/text、默认 parameters、workspaceSchema 与页面 URL。`?agent_mode=True` 返回纯文本文档，业务请求移除此参数。\n\n## 2. 生成图片，上传一次，显示压缩衍生图\n\n先让 coding agent 按生成图片文档产出文件；Studio 不暗中调用生成模型。图片可以来自用户素材或生成结果。上传走现有素材 API：\n\n```sh\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \\\n  -F kind=image -F assetOnly=true -F files=@hero.png \"$BASE/api/upload\"\n```\n\n返回 `assets` UUID 数组及对应 `files` 元数据。取 `assets[0]` 作为 assetId。上传不单独发帖；设计创建时才自动关联 Wiki post。不要把 Base64、任意远程 URL、HTML 或 SVG 塞入参数。\n\n原素材保留在素材库，**页面展示只请求压缩 WebP**。以 assetId 引用素材，不必自行再上传缩略图：\n\n```sh\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \\\n  \"$BASE/api/preview?source=%2Fapi%2Fmedia%2FASSET_UUID&width=960\" -o hero-preview.webp\n```\n\nwidth 只允许 240/480/960/1280；小图预算 100KB，大图预算 220KB，复杂图片会降低尺寸/质量。原生页面按槽位显示宽度和像素密度选择 srcset 衍生图，保留 fit/cropX/cropY/zoom。目录使用原生文字与 CSS 色块，不加载参考原图；旧工具箱参考图也使用压缩预览。`/api/media/{id}` 是素材原件读取接口，不应用作展示图片的 src。\n\n## 3. 创建：POST /api/studio/designs\n\n创建和更新共用内容字段 `name,parameters`；`schemaVersion` 可省略，单页当前支持 1（多页使用上述独立 series API 的2）。创建额外传 `layoutId`，不传 revision 或 id。\n\n```sh\ncurl -fsS -X POST \"$BASE/api/studio/designs\" \\\n  -H \"Authorization: Bearer $PROMPT_TOKEN\" -H 'Content-Type: application/json' \\\n  -d '{\"schemaVersion\":1,\"layoutId\":\"standard-01\",\"name\":\"观察日常\",\"parameters\":{\"paper\":\"#edf0ef\",\"texts\":{\"T01\":{\"value\":\"观察日常\\n记录灵感\",\"fontFamily\":\"serif\",\"color\":\"#23424b\"},\"T02\":{\"value\":\"让每一页只讲一件事。\",\"lineHeight\":1.4}},\"images\":{\"I01\":{\"color\":\"#73929a\",\"fit\":\"cover\",\"cropX\":50,\"cropY\":45,\"zoom\":1}},\"decorations\":{\"D01\":{\"color\":\"#73929a\"}}}}'\n```\n\n有图片时在 I01 加 `assetId:\"上传返回的UUID\"`。固定排版只需改为所选 `layoutId`，并按 schema 选择元素 ID。例如 ref-01 支持 `texts.T01`、`texts.T02` 与 `images.I01`。\n\n201 返回 `{design}`。design 包含：\n\n| 字段 | 含义 |\n| --- | --- |\n| id / layoutId / family | 持久化 UUID、不可变模板 ID、standard 或 fixed |\n| schemaVersion / revision | 参数契约版本（1）、记录修订号（从1递增） |\n| name / parameters | 名称与规范化内容；省略的分组返回空对象 |\n| url / renderUrl | 同一个原生 HTML/CSS 页面 URL |\n| schemaUrl | 当前模板参数地址 |\n| postId / postUrl | 自动创建并在后续更新中复用的 Wiki post |\n| archived / archivedAt | 可恢复归档状态与时间 |\n| createdAt / updatedAt | 创建与最后修改时间 |\n| legacySvgUrl | 固定排版的旧 SVG 导出地址，标准排版为 null |\n\n创建设计与 Wiki post 在同一数据库事务内完成，失败整体回滚。更新同一设计复用同一 post；手工编辑过的 Wiki 正文、标题、标签、封面不会被参数更新覆盖。\n\n## 4. 读取与打开\n\n```sh\nID=创建返回的UUID\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/api/studio/designs/$ID\"\ncurl -fsS -H \"Authorization: Bearer $PROMPT_TOKEN\" \"$BASE/api/studio/designs?layoutId=standard-01&limit=20\"\n```\n\n读取返回 `{design}`，没有副作用。列表默认只列未归档记录；`archived=true` 只列归档记录；limit 为1–50，默认20；`nextCursor` 作为下一页 before。layoutId 可省略。\n\n直接打开创建响应中的 `design.url`：`/studio/template-layout?id={UUID}`。这个 UUID 对应数据库里 API 保存的模板、图片与文字，服务端按记录渲染最终 HTML/CSS。链接中无需携带 layoutId，无需打开 `/studio` 选择模板，也没有编辑按钮、双击编辑或右键编辑。`standard-01` 与 `ref-17` 是模板 ID，不是保存记录的 UUID。\n\n`/studio/designs/{UUID}` 与旧 `/studio/layouts/{layoutId}?id={UUID}` 兼容跳转到同一个结果页。缺失、非法、不存在或已归档的 ID 返回404，不会显示空模板或编辑器；旧链接模板与记录不匹配也返回404。归档设计仍能经 API 读取以恢复。\n\n## 5. 更新：PATCH /api/studio/designs/{id}\n\n先 GET，保留所有未改字段，再整体替换 parameters；不是深度合并。以下假设刚读到 revision=1：\n\n```sh\ncurl -fsS -X PATCH \"$BASE/api/studio/designs/$ID\" \\\n  -H \"Authorization: Bearer $PROMPT_TOKEN\" -H 'Content-Type: application/json' \\\n  -d '{\"name\":\"观察日常 · 修订\",\"revision\":1,\"parameters\":{\"texts\":{\"T01\":{\"value\":\"新的标题\"}},\"images\":{},\"decorations\":{}}}'\n```\n\n200 返回新 design，revision 增加。过期 revision 返回409，重新 GET 并合并后再提交；不要盲目重试。不接受 layoutId、id、url、postId 等返回字段；不能直接把整个 design 作为 body。另存副本使用 POST 创建新 UUID。\n\n## 6. 删除与恢复\n\nDELETE 采用可恢复归档，不物理删除参数、素材或 Wiki post。和更新一样必须提供最新 revision；自动同步关联 post 的归档状态。\n\n```sh\ncurl -fsS -X DELETE \"$BASE/api/studio/designs/$ID\" \\\n  -H \"Authorization: Bearer $PROMPT_TOKEN\" -H 'Content-Type: application/json' -d '{\"revision\":2}'\n# 删除后读取新

 不要编造 ID，也不要把模板预览链接当作最终结果。API 保存成功并返回真实 UUID 才算完成。以下文档足以通过 HTTP 完成流程，无需使用编辑器。
 
+## 多页作品：从创作 brief 到可发布文件（schemaVersion 2）
+
+多页作品由 coding agent 完成创作决策与图像生成，网站负责封闭参数验证、事务保存与原生渲染。无需模型服务、模型密钥或编辑器。先形成主题、读者、意图、逐页分镜，再生成需要的图片，最后通过 HTTP 保存整组作品。封面、正文、结尾共用一个真实 UUID、修订号和 Wiki post。
+
+### 完整内容与视觉模型
+
+创建 `POST /api/studio/series`，body 为 `{schemaVersion:2,name,document}`。读取/整体修订使用 `GET/PATCH /api/studio/series/{id}`；PATCH 额外提供最新 revision。最大512KB，未知字段会拒绝。document：
+
+- `version:1`：多页文档结构版本。
+- `brief`：topic、audience、intent、designIntent、imageStrategy，均为必填非空文字，最多2000字符。分别说明主题、读者、内容目标、完整设计描述和配图策略。
+- `style.version`：agent 指定的样式版本标识（最多80字符），如 `autumn-journal/1`。它用于记录创作版本；不锁定未来网站渲染器，精确交付请同时保留导出文件和 manifest。
+- `style.palette`：paper、ink、muted、accent，均为 #RRGGBB。
+- `style.typography`：title、body、caption 三种层级，每项包含 fontFamily（sans/serif/mono）、fontSize（0.1–40）、fontWeight（100–900）、lineHeight（0.5–4）、letterSpacing（-5–10）。字号和字距以120宽参考画板为单位，固定模板按画板宽度同比换算。
+- `style.spacing`：margin（4–16）、gap（1–10），并要求 `2*margin+4*gap<=48`。标准排版据此计算标题、图片、正文和分隔线的位置；固定模板保留原构图，用 layers 显式调整位置。
+- `sources`：最多100项，每项 assetId、author、license、url、prompt、tool 全部必填，文字最多4000字符。url 是 http(s) 来源地址或 `generated`。用户照片记录来源与授权；生成图记录完整提示词和工具，不把 AI 图写成摄影原作。所有被页面引用的图片必须有来源记录。
+- `pages`：本工作流支持3–18页（这是本服务的约束，不宣称是平台实时上限）。每页 key 唯一（小写字母/数字/连字符，最多60位）、role（首项 cover，中间 body，末项 ending）、layoutId、intent（最多1000字符）、bindings、parameters。parameters 继续使用下文封闭的单页参数契约。
+- `pages[].bindings`：把实际文字元素 ID 映射到 title/body/caption，例如 `{T01:"title",T02:"body",T03:"caption"}`。被绑定元素必须提供文案。共享字体、墨色和纸色会参与真实渲染；单元素显式值优先覆盖。所有可见文字必须提供或明确隐藏，避免默认占位文案泄漏。图片默认色与装饰默认色取 accent。
+
+标准排版可直接沿用 T01/T02/T03/I01/D01；固定排版先读对应模板 API，元素不能混用。agent 必须控制标题长度和正文密度，不能把“已保存”当成“已验收”。同组图片建议统一比例；导出器遇到混合比例会拒绝，agent 应改用同一画板并调整内容布局。
+
+### 一次保存，一条直接结果链接
+
+```sh
+# series.json 包含完整 document，示例文件见仓库 content/studio-examples/autumn-journal.json
+curl -fsS -X POST "$BASE/api/studio/series" \
+ -H "Authorization: Bearer $PROMPT_TOKEN" -H 'Content-Type: application/json' \
+ --data-binary @series.json
+# 返回 {design}：schemaVersion=2、document、id、revision、url、postId 等
+curl -fsS -H "Authorization: Bearer $PROMPT_TOKEN" "$BASE/api/studio/series/$ID"
+```
+
+创建响应的 `design.url` 仍是 `/studio/template-layout?id={UUID}`；直接展示全部页，无需选模板。`&page=2` 只显示第2页，非法页码返回404。页面是服务端原生文字与 CSS，图片走 /api/preview。创建与全部页验证、Wiki post 处于同一事务，任一页无效整组不保存。PATCH 整体替换 document，revision 冲突返回409；先重新读取并合并。单页 PATCH 接口会拒绝修改多页作品，避免只改封面导致组内不一致。可从 designs 列表发现作品，schemaVersion 区分1与2。
+
+归档 `DELETE /api/studio/series/{id}` body `{revision}`；恢复 `POST` 同一路径 body `{revision,archived:false}`。归档后结果页和导出计划返回404，API 仍能读取并恢复；参数、素材和 Wiki post 保留。更新复用原 Wiki post，手工编辑过的正文不被覆盖。
+
+### 高质量导出与验收
+
+`GET /api/studio/series/{id}/export` 返回固定顺序的导出计划：id、revision、每页 key/role/number、filename、width/height、原生渲染 url。计划本身不生成位图。示例统一为3:4、1080×1440 PNG；其他固定模板保留自己的画板比例，不拉伸。该尺寸是本流程的交付规格；发布前还须在小红书当前发布界面复核裁切及文件限制，本站不自动发布。
+
+导出 URL 带 `&page=N&export=1`，画布在1080 CSS像素下重新布局原生文字，不把860宽或手机截图放大。图片使用 `/api/preview?source=...&width=2160&profile=export`：WebP质量95，不为常规缩略图预算降低尺寸，不放大小原件。普通展示仍使用240/480/960/1280及100KB/220KB预算。
+
+在用户已确认的 **ces-control / aliyun-ces-control** 上运行仓库 `scripts/export-studio-series.cjs`，使用既有测试镜像的 playwright-core、sharp、Chromium 和中文字体。只访问 `http://8.211.154.134:18131`，认证保留进程内。设置 STUDIO_DESIGN_ID、STUDIO_EXPORT_DIR、AUTH_CONFIG_FILE（或由现有登录方式提供的 PROMPT_TOKEN），不在命令行或文件中存令牌。不得在用户本机启动编译、容器构建或预览服务器。
+
+脚本逐页检查字体和图片加载、文字溢出、图片原生分辨率与裁切缩放、相同画板比例、页序、最终PNG像素、导出前后revision一致；记录实际字体、SHA256及manifest。额外生成桌面1200宽和手机390宽整组截图供视觉检查。自动检查通过后，agent 仍须逐页看PNG，核对中文缺字、主体裁切、阅读顺序、留白和系列一致性。检查失败修订 document，重新导出；不能把失败文件当成可发布结果。
+
+最终交付：真实设计结果链接、按01/02/03排序的PNG、完整design.json、manifest.json、素材来源与提示词、简短发布文案。生成图、保存成功、导出成功、人工视觉通过、PR待合并、线上部署验收应分别如实报告。未合并代码的能力不可写成线上已可用。
+
+### 可复现三页示例
+
+仓库 `content/studio-examples/autumn-journal.json` 是完整的三页内容与样式文档：封面“把秋天装进一页”、正文“先看见再记录”、结尾“留一点白给下一次”。它不含虚构素材 UUID，空图片位仅用于契约测试。真实制作时先生成银杏母图，再上传取得assetId，在每页 I01 加入该 UUID，并在 sources 记录完整来源。不要把无图夹具当作已完成作品。
+
+推荐在 ces-control 的仓库目录直接执行 `bash scripts/deliver-studio-series.sh /absolute/path/series.json /absolute/path/ginkgo-master.png /absolute/path/provenance.json /absolute/path/output-directory`：该脚本复用已部署认证卷和匹配的CI镜像，依次保存、导出并留下证据，不启动构建或部署。成品位于 output-directory/revision-N/；已成功导出的修订会核对哈希后复用，后续修订使用新目录，避免覆盖或混入旧页。
+
+底层保存命令 `node /app/auth-cli.cjs run /delivery/scripts/save-studio-series.mjs /absolute/path/series.json /absolute/path/ginkgo-master.png /absolute/path/provenance.json /absolute/path/output-directory` 经既有 auth-cli run 在远程执行，上传素材并填写所有页面引用后，保存真实作品，写出请求、响应和状态文件。重复运行会读取已保存状态，防止在成功后重复创建；出现网络结果不明时先核对素材/设计列表，不盲目重试。脚本仅在传入文件后写入作品，不自动发布到小红书。

 ## 两类排版，同一内容模型
 
 - **标准排版**：`standard-01`，120×160 单位。沿用原 Studio 图文页的标题、正文、栏目结构，增加主题图片与分隔线。T01 主标题、T02 正文、T03 栏目、I01 图片、D01 分隔线。所有内容和位置可设置，也能增加原生元素。
 - **固定排版**：`ref-01` 至 `ref-27`，保留各自画板、出血、圆形、斜切、竖题和字体构图。先读取模板，按实际 T/I/D ID 填入内容。不能假定各模板拥有相同元素。
 
-两类都使用 `/api/studio/designs` 的真实 CRUD。创建额外指定 layoutId；更新从 URL 确定 ID，模板关联不能修改。更换模板应创建新记录，避免把旧元素 ID 错套到新模板。调用方无需打开 `/studio` 或操作编辑器。模板由 agent 经 API 选择，图片和文字由 API 保存，用户只打开结果链接。现有独立工具箱功能保持可用。
