生产构建会生成文档路由；新增或修改文档后重新运行 build。开发模式按请求读取内容。
main 推送通过 CI 验证后自动部署；Pull Request 只验证，不部署。工作流也支持手动触发。
## Endor 概念图
`content/docs/00-endor-concepts-draft.md` 解释全球入口、区域网关与 Runtime、分片、CDN、身份及跨区恢复的概念设计，页面为 `/docs/00-endor-concepts-draft`。
图形源码位于 `tools/figures/src/endor_figures/architecture.py`，由 `pnpm figures` 生成 `apps/docs/public/figures/endor-architecture.svg`。Python 负责可复现的节点、全连接和复制路径，React 查看器提供放大、滚动与 SVG 下载。无需外部图标、字体或绘图服务。图中的数量是示意，身份服务/CDN 接入属于建议，所有未实现的关系均以草案说明。
拓扑检查：`uv run --locked --project tools/figures python -m unittest discover -s tools/figures/tests -v`。容器检查流程会运行同一检查。
## CI/CD 与缓存
`.gitea/workflows/ci-deploy.yml` 使用已有 ces-control Runner，不修改共享 Runner 配置。

# 理解 Endor：从全球入口到对象数据
Endor 的概念模型把全球访问、区域运行时和对象数据连接起来：请求从统一入口进入，在合适的区域找到 Nexus Runtime，再由它承载的 Aster VM 执行对象操作。数据以分片组织，在区域内保持高可用，并为每个分片安排跨区域恢复目标。
> **概念设计草案**：本文按当前讨论绘制目标架构，不表示这些组件和协议已经全部实现。图中的区域、节点、分片数量仅为示例；CDN 和身份服务的接入方式是建议方案。
## 架构总览
![Endor 概念拓扑：全球入口连接北美与亚洲，各区 Traefik 与 Nexus Runtime 全连接，每个 Nexus 配一个 Aster VM；数据分片包含 PostgreSQL、Aerarium 和 S3，并具有区域内副本和跨区备份](/figures/endor-architecture.svg)
图中绿色/蓝色实线表示请求路径或区域内数据依赖，紫色虚线表示身份控制与公钥分发，蓝色点线表示 CDN 回源，金色虚线表示跨区复制和备份。连线表示可达或依赖关系，**不表示请求向所有节点广播**。
图的编排由 Python 生成 SVG：节点图标、二分全连接和复制线路都能复现和编辑。Python 更适合这张静态架构图；页面查看、缩放与下载由 TypeScript/React 负责。
## 全球入口与区域入口
客户端包括浏览器、Tessera、SDK 和 CLI。`endorphin API` 是逻辑上的全球流量入口，尚未在本文规定一个真实的域名。全球调度根据健康、延迟、项目归属和数据放置策略选择区域；不能只选择网络最近的区域而忽略对象在哪个分片。
示例使用北美和亚洲两个区域。每个区域有自己的负载均衡入口，下面是 Traefik 网关，负责按配置进行 TLS、主机名或路径路由。图中的第二个 Traefik 标记为 **HA 副本**：多副本是生产冗余选项，单实例概念部署不要求两个网关。
### 为什么画成二分全连接
每个区域示例中有两个 Traefik 和三个 Nexus Runtime，画出全部六条边，即二分图 **K₂,₃**。每个网关都能把请求路由到任意一个符合条件的健康 Runtime，避免把一个网关固定绑定到一个运行时。
这是逻辑可达关系。实际转发仍需考虑服务发现、健康检查、项目和对象归属，以及有状态连接的路由策略；Runtime 之间并没有因此形成全连接网状网络。
## Nexus Runtime 与 Aster VM
此处采用 **一个 Nexus Runtime 节点配一个 Aster VM** 的概念约定。Nexus 表示对外接入与运行时承载边界，Aster VM 执行对象相关逻辑。图中每台服务器下面都单独画出一个 VM 芯片，避免把多个 VM 误读成另一个共享池。
请求经过区域入口和 Traefik 到达 Nexus，再定位目标分片。图中运行时下方的连接汇入分片路由层，表示节点可以按归属访问区域分片，**不是**「Runtime 1 只能访问分片 1」。对象身份、远程引用、生命周期与调用语义仍需结合[节点与对象挂载草案](/docs/02-mounting-draft)继续定义。
## 三类存储如何组成一个分片
示例中每个区域都有两个逻辑数据分片。每个分片展示三个协作部分，它们是逻辑数据边界，不要求一分片对应三台独占物理机器。
| 部分 | 概念职责 | 依赖关系 |
| ------------------------- | ------------------------------------------------------------ | ------------------------- |
| PostgreSQL | 结构化元数据、对象索引及需要事务约束的状态；具体数据模型待定 | 提供关系数据与事务能力 |
| Aerarium Object data pool | 对象数据的逻辑组织与访问层；不是把 S3 换一个名字 | 同时依赖 PostgreSQL 与 S3 |
| S3 兼容存储 | Blob、文件、快照和适合对象存储的数据；具体格式待定 | 提供对象持久化能力 |
图中 Aerarium 向左右各画一条依赖箭头，分别连接 PostgreSQL 和 S3。它们**不是**三个互不相关的平行数据池。
### 区域内高可用
每个存储图标下面有一个小型副本图标，用点线连接，表示本区域的高可用副本。生产部署应跨独立故障域放置，具体可以是不同可用区或独立节点。
这是逻辑 HA 要求，各层的实现不同：PostgreSQL 可以使用主备复制，Aerarium 需要自己的状态协调和故障恢复设计，S3 的耐久性与副本由选定的存储系统提供。图不强制三者采用同一种同步复制机制，也不把单纯增加副本等同于已经实现故障自动切换。
## 每个分片都要有跨区恢复目标
区域内副本解决本地节点或故障域失效；跨区备份解决整个区域不可用。四个源分片均有独立的异地目标：
| 源分片 | 异地备份位置 | 覆盖内容 |
| ------------ | ------------ | -------------------------------------------- |
| NA-01、NA-02 | 亚洲区域 | 各分片的 PostgreSQL、Aerarium 状态和 S3 数据 |
| AS-01、AS-02 | 北美区域 | 各分片的 PostgreSQL、Aerarium 状态和 S3 数据 |
每个目标应保留可校验的恢复清单，将关系数据恢复点、对象池元数据版本与 S3 对象版本关联起来；不能只复制其中一种存储就宣称整个分片可恢复。图中的金色线路明确跨越区域，备份集按源分片编号标识。
### “最终一定拿到数据”需要怎样的保证
设计目标是：正常访问优先本区域；本地不可用时，仍能找到异地保存的数据。需要区分两类能力：
- **异地在线副本**：已有服务能读取它；追平状态、授权和路由满足要求后，才可承担故障读取。
- **异地备份**：保留了恢复材料，需要恢复 PostgreSQL、重建 Aerarium 并校验对象版本后才能提供服务，通常更慢。
> **保证边界**：异步复制与定期备份不能无条件保证最后一笔已确认写入不会丢失。若源区在复制完成前永久丢失，未到达异地的数据仍可能丢失。当前图承诺的是“已校验恢复点可恢复”的目标，而非已实现的零数据丢失保证。
要实现更强的承诺，需要明确写入确认条件。例如必须等跨区持久化成功才返回写入成功，或者以独立耐久日志作为重放来源，并设计重试、校验、告警与恢复演练。这会增加延迟或实现成本，不能只靠一条“最终一致”虚线获得。
后续设计需要分别确定 **RPO**（可接受的数据丢失窗口）和 **RTO**（恢复服务所需时间），以及备份保留、删除传播、加密密钥和数据跨区合规策略。
## CDN 应该放在哪里
建议把 CDN 作为面向静态和可缓存内容的边缘路径，与动态 API 调度区分：
1. 客户端请求静态前端、文档或允许缓存的对象，优先命中 CDN；命中后直接返回，无需访问 Nexus。
2. 缓存未命中时，CDN 回源到指定的 S3 兼容存储，或专门的资源服务。图中仅示例回源到亚洲区域的 S3，并不把亚洲设为唯一源站。
3. 私有对象可使用短时签名 URL、受控回源或独立授权服务。缓存键、过期、权限隔离和失效策略需要单独设计。
4. 登录、写入、实时连接和个性化动态 API 默认不进入共享缓存。CDN 能代理这些流量，不代表应该缓存这些响应。
CDN 是可替换、可选的加速层，不是数据库副本，也不承担跨区灾难恢复的唯一责任。
## 身份服务是否依赖 Nexus
**建议在逻辑上独立，不把它画成依赖某个业务 Nexus 的服务。** 客户端向身份服务登录或刷新凭证；Nexus 验证访问凭证、项目归属和操作权限后才接受业务请求。
图中紫色线路表示公钥或认证配置的分发关系：使用适当的签名访问令牌方案时，Nexus 可以缓存 JWKS，在本地完成签名及必要声明校验。具体访问令牌格式尚未确定，不能把 OpenID Connect 的 ID Token 直接当作所有 API 的授权凭证。
如果采用不透明令牌、即时撤销或实时策略评估，可能需要在线内省或授权查询；这会引入身份服务的在线依赖，需要单独设计可用性和失败策略。已有令牌可离线验证也不意味着公钥轮换、过期、撤销和权限变化可以不处理。
身份服务本身仍可以使用 PostgreSQL、缓存和密钥管理等基础设施；**逻辑独立不等于没有存储依赖**。将来即使选择在通用 Nexus 基础设施上托管它，也应保留独立的故障和信任边界，避免启动、登录与业务运行时形成循环依赖。
## 继续确定的设计边界
- 全球入口如何发现项目与分片的归属，跨区域请求采用转发还是让客户端重连。
- Nexus 接入职责与 Aster VM 边界、连接亲和性和 Runtime 故障迁移。
- Aerarium 的数据格式、事务边界、对象版本和跨存储一致恢复点。
- 区域内 HA 的实际协议与跨区域 RPO/RTO、故障读取与恢复流程。
- 身份签发者、访问令牌验证与撤销机制，以及私有内容的 CDN 授权。

# Endor 概念页验收 · 2026-10-27
新增页面 `/docs/00-endor-concepts-draft`。按用户给出的五张参考图组织为清晰的矢量图标、节点、实线/点线和二分全连接；未使用 Mermaid 自动矩形流程图，也未引入外部图标、字体或 CDN。
## 内容与图形核对
- 全球 `endorphin API` 入口分流到北美、亚洲各自的区域负载均衡入口。
- 每区两个 Traefik（冗余可选，第二个标 HA）与三个 Nexus Runtime 构成 K₂,₃；总共12条网关到 Runtime 边，六个 Nexus 各配一个 Aster VM。
- 四个区域分片分别有 PostgreSQL、Aerarium、S3 图标；Aerarium 指向另外两种存储。各层均有点线连接的区域内小型副本图标。
- 四个源分片各有独立的金色跨区线路和同编号异地备份集，备份位置明确为对侧区域。
- CDN 作为可选缓存路径，命中直接返回，点线回源到示例 S3；动态 API 和登录不默认进入共享缓存。
- 身份服务以独立控制服务建议呈现，客户端登录与签发、公钥分发和 Nexus 校验分别说明；没有宣称已实现的部署关系。
- 正文区分异步备份、在线副本、恢复点、RPO/RTO，说明“最后一笔写入绝不丢失”需要额外写入确认与耐久协议。
## 验证
- `pnpm lint`、`pnpm typecheck`：通过。
- `pnpm --filter @endor/docs run build --webpack`：通过，新增文档静态路由成功生成。本机采用前次验收已确定的 webpack 构建方式，仓库原有构建配置不变。
- `pnpm figures`：通过；独立 SVG，无外部图像资源。
- `uv run --locked --project tools/figures python -m unittest discover -s tools/figures/tests -v`：通过，覆盖重复生成字节一致、6个 VM、每区三个 Runtime/两个网关、12条全连接边、四个分片各有备份目标。该检查也接入容器校验脚本。
- 现有四个 CI/部署脚本单元测试通过。
- 实际生产预览 `127.0.0.1:3016`：检查桌面与390px手机。手机正文页面宽度390px，没有页面横向溢出；查看器放大至45%时内容宽808px，仅在宽372px的图面区域滚动，正文仍宽390px。
- 浏览器实际验证放大、适应宽度、关闭与 Escape；关闭后焦点恢复至“放大查看”按钮。桌面从适应状态放大到94%，按实际容器宽度计算比例。
- SVG 下载链接指向本地生成文件，并设置下载文件名。全部路由及 SVG/JS/CSS 的 HTTP 冒烟由现有 `scripts/smoke.py` 检查。
- 页面与查看器捕获的浏览器 error/warn 日志为空。
## 截图
`architecture.png` 为完整 SVG 的实际浏览器渲染；`page-desktop.png` / `page-mobile.png` 为正文页面；`viewer-desktop.png` / `viewer-zoom.png` 为桌面图形查看与缩放；`viewer-mobile.png` / `viewer-mobile-zoom.png` 为手机适应与缩放。
本次未改变共享 Runner、Docker 缓存、部署端口与回退策略。CDN/身份服务讨论为架构建议，不代表把当前文档站接到新的外部服务。
