+## 位图默认发布压缩版本
+
+SVG 保留可编辑矢量格式；漫画、照片等位图的原始 PNG、JPEG 放在 `tools/figures/assets`，不放进 `public`。浏览器只使用生成的 WebP，正文、点击放大和图片适应屏幕都使用同一个压缩地址。
+
+共享策略位于 `content/image-policy.json`：默认最大宽度 1600 像素、WebP 质量 82、每张图最多 192 KiB，不放大小图。修改策略后重新生成并检查公式、细线和小字是否清晰。

+
+```sh

+原图相对 `tools/figures/assets` 的路径会映射到 `apps/docs/public/figures` 下同名的 `.webp`。例如 `endor-review-gate.png` 对应 `/figures/endor-review-gate.webp`。文档只嵌入后一个地址，制作原稿不随网页发布。
+
+远程生产构建会运行压缩脚本；CI 先生成 WebP，再重新编码核对产物与原稿、策略是否一致。WebP 是构建派生文件，不必在本机生成或提交；Git 保存原稿、制作记录与共享策略。检查同时拒绝公开目录里的原始位图及 Markdown 图片或 HTML img 直接引用的原始 PNG、JPEG。SVG 无需转成位图，仍按前述流程提交可编辑输出。

 这一定位希望形成的体验是：**对象池构成持续可用的工作世界，Agent 成为其中执行工作的主体，Endor 语言让对象和行为能够被表达、检查与组合。** 用户与 AI 因而可以在同一套对象基础上发起、接续和检查工作。这是本文的设计方向，不表示所有系统能力已经实现。
 
+## 让产出成为检查下一次产出的帮手
+
+![Coding Agent 不断产出相同的原始文件：上方待检查文件积累为积分 dW，单人的检查门保持固定能力 C₀；下方 Endor 只把本次新增文件 dW 送到人与检查门前，处理完成的文件变成结构化蓝色帮手，箭头回到检查门，表示历史成果积累为新的检查能力](/figures/endor-review-gate.webp)
+![检查台版：上方单人检查台面对积累的待处理文件；下方只检查本次新增文件，已处理文件变成蓝色帮手，向检查台贡献更多检查工具](/figures/endor-review-desk.webp)
+
+两张漫画用检查门与检查台表达同一个目标，可用左右按钮或下方圆点切换。
+
+上方把 Coding Agent 比作一台不断吐出工作结果的机器。机器可以持续产出，但人的时间和精力没有同步增长；等待检查的材料越积越多。虚线圈出的 **∫dW** 表示累积的待处理工作，门上的 **C₀** 表示在这个对比中保持不变的检查能力。通过门、带上勾的文件才表示已处理的结果。
+
+下方的机器吐出同样的原始文件，改变的是 Endor 如何组织和接续这些产出。人和检查门直接面对的是这次新增的 **dW**；已经处理的文件被组织成有类型、来源、关系与可调用能力的对象，成为图里的蓝色帮手。帮手的箭头指向检查门，表达它们为后续检查提供支持，而不是让新生成的结果自己证明自己正确。
+
+例如，已确认的需求可以成为验收条件；稳定的接口约定可以帮助发现不兼容修改；图片发布规则可以检查下一份文档有没有直接嵌入原图。**过去的产出从待处理的负担，逐步变成帮助人处理新工作的能力。** 新结果是否符合要求，仍需要适用的检查逻辑与人的判断。
+
+门上的 **C₀ + k∫dW** 表示我们希望实现的积累效应：在原有能力上，增加由历史成果转化而来的可复用检查能力。这里的积分、微分和系数 k 是设计隐喻，不是性能公式或实测结论；只有经过确认、适合复用并保持有效的成果才能贡献能力，产出数量不等于正确性，实际检查也可能需要重新覆盖受影响的历史对象。
+
+> **设计目标**：这张漫画表达希望建立的工作组织方式，不表示当前 Endor 已能自动把任意文件变成检查工具。要兑现它，需要保存来源和依赖、表达检查规则、执行检查，并把失败与待确认事项呈现给人。
+
+## 从压缩图片想到的继承：让要求成为共同能力
+
+这张漫画也带来一个具体要求：**文档在浏览器中默认使用压缩图，原图留作制作与归档，不因打开正文或放大图片就下载原图。** 如果很多文档都需要这条规则，用户不应该每次写文档时重新提醒一次。
+
+单次 Coding Agent 对话中的“记得压缩图片”，通常首先是一项需要读取、理解和落实的指令。指令可以放进项目约定、技能或模板，也可以让 Agent 写出共享压缩脚本；这些都能减少重复劳动。但一句自然语言要求本身，并没有自动建立“这类文档如何派生、谁沿用默认行为、哪个文档允许覆盖”的类型与行为关系。这里讨论的是这种**可持续、可检查的继承**，不是说 Agent 不能编写使用继承的程序。
+
+### 为什么 Endor 的设计能承载继承
+
+在现有设计中，文档、图片、类型定义、函数和 Agent 都进入同一对象体系。对象具有可引用的身份，类型可以表达对象的结构与能力，函数可以表达处理行为；继承、实例化与代码依赖可以保存为有不同含义的关联。因此，“默认如何发布文档图片”可以被表达为一个可引用的共同定义，以及读取和执行它的行为，而不只是一段随对话流逝的提醒。
+
+沿着这个设计方向，可以把图片发布要求放到共享文档类型或其呈现策略上：普通文档沿用“优先压缩图”的默认行为，需要精确查看像素的专业文档再显式采用另一种策略。具体通过类型继承、策略对象委托还是能力组合实现，需要结合语言规则确定；不是因为对象之间有一个链接，就天然获得了继承。
+
+| 层次 | 压缩图例子中承担的职责 |
+| --- | --- |
+| 共同定义 | 保存默认图片尺寸、编码质量、字节预算及浏览器应使用的派生版本 |
+| 继承或委托关系 | 让采用共同定义的文档持续引用它，明确哪些行为来自共同来源 |
+| 实际处理能力 | 根据策略生成压缩版本，保留它与原图的来源关系，并让呈现入口选择压缩版本 |
+| 检查与覆盖 | 检查新产出是否符合默认要求；特例显式选择覆盖，并能说明生效的规则来自哪里 |
+
+关键不只是“记住用户偏好”，而是**规则有归属，使用者有关系，行为可以执行，结果能够检查**。当 Agent 新建同类文档时，它使用已有文档能力与策略，就能让之前确认的要求继续参与这次工作；人主要判断本次差异和真正的例外。这也是漫画里历史成果增强检查门的一个具体例子。
+
+定义和依赖是对象，使系统有基础追踪受影响的文档，并通过名称、类型与调用检查发现部分不一致；图片编码与发布仍需实际运行相应能力。“一切皆对象”本身不保证每份文档都调用正确的渲染器，也不自动决定规则修改后是否追溯更新历史文档。
+
+> **语义边界**：继承与委托、覆盖与冲突规则仍在[语言设计问题集的对象模型部分](/docs/language-design/05-questions)讨论中。父定义更新如何生效、文档是否绑定特定版本、多来源冲突如何处理，需要明确后才能成为稳定承诺。这里解释 Endor 为什么有承载这类继承的共同基础，以及希望形成的体验，不宣称这些规则已全部实现。
+
+### 本站现在怎样落实这条规则
+
+Tabularium 目前用共享构建策略落实这项要求：原图保存在非公开的制作目录，脚本统一生成有尺寸、质量与字节预算的 WebP，文档正文和放大查看都使用这个压缩版本。新增文档直接引用生成的图片，不需要逐篇重新实现压缩；构建检查会拒绝公开原始位图或直接嵌入原始 PNG、JPEG。
+
+这是今天在文档仓库里可以执行和验证的共享规则，具体工作流见[图形与脚本](/docs/03-figures)。它示范了“把一次提醒变成后续工作可复用的能力”，并不表示 Tabularium 这个 Next.js 网站已经运行了 Endor 的继承机制。

 ![从程序入口到对象操作的对比：上图中 OS 分出九个进程，按二、四、三个分为三组，对应三个程序；对象以进程内的随机小圆圈表示，用户通过程序入口访问。下图中 OS 只分出少量进程，承载 Endorphin 的对象关系网络，用户与 AI 用多条贝塞尔曲线直接指向选定对象；OS、进程区与 Endorphin 都位于 Endor OS 边界内](/figures/endor-purpose.svg)

+Endor inspection desk comic — approved second slide
+
+Source: built-in image_gen; physics inspection-bench variant with corrected top-row flow.
+Original: exec-432e0f3d-d01d-4658-b5d5-0c63db95e472.png
+The user selected this alongside the gate variant for one carousel.
+
+The two identical machines emit raw papers. Above, a dashed integral dW boundary
+encloses the backlog BEFORE one person's fixed-capacity C0 inspection desk.
+Below, a dashed dW boundary encloses the one new paper being inspected. Earlier
+checked outputs become structured document helpers that contribute additional
+magnifiers to the Endor desk, whose capacity is C0 + k integral dW.
+
+Store this PNG as the production master outside public. The confirmed remote
+runner generates /figures/endor-review-desk.webp using content/image-policy.json.

+Endor review gate comic — approved source
+
+Source: built-in image_gen, physics gate variant, approved by the user on 2026-10-28.
+Original: exec-380f8db3-6450-4981-97df-473c13a62223.png
+The PNG is the production master, not a public browser asset.
+The confirmed remote runner generates the browser WebP with:
+pnpm --filter @endor/docs images
+
+Visual specification:
+Two rows, white background, charcoal outlines, blue accents, identical coding
+machines emitting identical raw sheets. Top: accumulated unchecked sheets inside
+a dashed integral dW boundary, one person and a fixed C0 inspection gate, checked
+output after the gate. Bottom: one new sheet inside a dashed dW boundary directly
+inspected by a stick figure at an Endor gate. Gate capacity is C0 + k integral dW.
+Checked output becomes a structured document helper, joins historical helpers,
+and blue arrows from helpers feed the gate to increase inspection capability.
+No dialogue or explanatory prose. Math is a conceptual metaphor, not measured data.
+
+The bitmap master retains the approved artwork, including its mathematical
+symbols. Browser optimization changes encoding and dimensions only.
