fix(chat): image send 500 + table/newline formatting (v2026.07.20.1708)

- _build_system_prompt 末尾增加【最高优先级覆盖规则】：用户明确选择技能/MCP 并询问其介绍/功能/用法时，
  必须只基于该工具资料作答，禁止引用平台知识库中技能市场/MCP/平台能力的通用描述。
- _generate_media_task 增加启动/结束日志，对图像生成加 90s 超时、视频 300s 超时，避免异步任务挂死导致前端一直显示“生成中”。

+# NOTE: This workflow is DORMANT until a Gitea act_runner is registered with
+# this repo. The active gate today is the host-side pre-push hook
+# (scripts/git-hooks/pre-push) + scripts/ci_gate.py, because our deployment
+# model keeps the app running in a long-lived `qihu-aiflow` container on the

+#
+# To activate later:

+#   2. Register it against this repo with label `ubuntu-latest`.
+#   3. The runner can then `docker exec qihu-aiflow ...` to reach the app.

+# .impeccable.md — 七虎AI 设计上下文
+
+本文件为 `impeccable` 技能提供项目级设计上下文。完整规范见 **`DESIGN.md`**（单一事实源）与 `design-system/MASTER.md`。
+
+## Audience & Use Case
+七虎 AI 是面向企业与开发者的 **AI PaaS 平台**：智能体编排、技能/市场、模型库、工作流、IM Bot（个人微信）。使用者是开发者与运营人员，需要高密度、可信、精密的控制台界面。
+
+## Brand & Tone
+- **风格**：温暖科技感 + 极简主义（Warm Tech Minimalism）。
+- **唯一品牌色**：靛蓝 `#5B5FED`（hover `#4A4ECC`，浅底 `#EEEDFF`）。语义色仅表状态（成功 `#219B5E` / 警告 `#E8922C` / 错误 `#D9383A` / 信息 `#3B82F6`）。
+- **基调**：专业、可信、有温度；留白与柔和阴影营造呼吸感；动效克制（150–300ms）。
+
+## Tech & Constraints
+- 前端：React 18 + TypeScript + Vite 5，HashRouter，浅色主题。
+- 设计 token 全在 `frontend/src/styles/global.css` 的 `:root`（颜色/间距/圆角/字体/阴影）。**新增视觉必须先加 token，禁止散落 hex。**
+- 字体：Inter（文本）+ JetBrains Mono（代码/ID/参数）。
+- 图标：**Lucide**，禁止 emoji 当图标。
+- 布局：左侧 sidebar（240/折叠64）+ 顶 header（56）+ 主内容区；详情用右侧 drawer。
+
+## Build & Verify（交付铁律）
+1. 改完 `frontend/src` 后必须在容器内 `npm run build`。
+2. 校验新 `dist` 确实含改动（grep 标记或构建日志），再请用户**硬刷新验收**。
+3. 每轮收工：`git commit + push` 到 `git.qihuyun.com`，并 `docker commit` 同名镜像（`qihuaiflow:with-deps`）+ 备份上一版，确保容器重建不丢。
+
+## Quality Bar（impeccable 验收）
+- 所有可点击元素有 `cursor:pointer` + hover + 可见 focus 环。
+- 对比度 ≥4.5:1；尊重 `prefers-reduced-motion`。
+- 响应式：375 / 768 / 1024 / 1440；无横向滚动。
+- 不引入第二品牌色、不用 emoji 图标、不用布局位移的 scale hover。

+# 七虎AI · DESIGN.md
+
+> **用途**：这是七虎 AI PaaS 平台的**唯一设计事实源（single source of truth）**。任何 AI 编码代理在新增/修改前端页面或组件时，必须读取本文件并严格遵守其中的设计 token、组件规范与 Do/Don't。
+> **风格方向**：温暖科技感 + 极简主义（Warm Tech Minimalism）。浅色为主（护眼雾白底），靛蓝 `#5B5FED` 为唯一品牌色；允许克制的「淡蓝紫→淡青蓝」渐变与轻量玻璃拟态（Glassmorphism）；前台必须符合 SEO/GEO 语义规范。
+> **生成方式**：基于平台现有 `frontend/src/styles/global.css` 的真实 token 固化升华，并经由 `ui-ux-pro-max` 技能的数据驱动生成器校验风格一致性。
+> 关联文件：`design-system/MASTER.md`（Master+Overrides 模式，含组件 CSS 样板）、`.impeccable.md`（impeccable 技能入口）。
+
+---
+
+## 1. Visual Theme & Atmosphere
+
+七虎 AI 是一个面向企业与开发者的 AI PaaS 平台（智能体编排、技能市场、模型库、工作流、IM Bot）。界面需要传达**专业、可信、精密**，同时带有**温度**（不冰冷）。
+
+- **Mood**：沉着、秩序、精密、可信任；用留白与柔和表面营造呼吸感。
+- **Density**：中高密度（开发者控制台），信息密集但不拥挤；关键操作常驻（header + sidebar）。
+- **Design philosophy**：
+  - 单一品牌色（靛蓝）贯穿全站，语义色只用于状态（成功/警告/错误/信息）。
+  - 表面层级用极浅灰阶 + 柔和阴影区分，而非重边框。
+  - 动效克制：150–300ms 缓动，仅做"提示"不抢戏。
+  - 全站浅色主题；深色模式暂不在范围内。
+
+## 2. Color Palette & Roles
+
+所有色值以 CSS 变量定义在 `global.css` 的 `:root`。**新增颜色必须先定义为 token，禁止散落硬编码 hex。**
+
+### 中性 / 表面
+| 语义名 | Hex | 角色 |
+|---|---|---|
+| `--color-bg-primary` | `#F8F9FB` | 页面主背景（最浅） |
+| `--color-bg-secondary` | `#FFFFFF` | 卡片 / 浮层表面 |
+| `--color-bg-tertiary` | `#F1F3F7` | 输入框底 / 次级表面 |
+| `--color-bg-hover` | `#EBEEF3` | hover 表面 |
+| `--color-bg-active` | `#E3E7F0` | 选中 / 激活表面 |
+
+### 文本
+| 语义名 | Hex | 角色 |
+|---|---|---|
+| `--color-text-primary` | `#101214` | 主文本 / 标题 |
+| `--color-text-secondary` | `#545A65` | 次要文本 |
+| `--color-text-tertiary` | `#8B919E` | 提示 / 占位 |
+| `--color-text-disabled` | `#BFC4CE` | 禁用 |
+| `--color-text-inverse` | `#FFFFFF` | 深色表面上的文本 |
+
+### 品牌 / 语义
+| 语义名 | Hex | 角色 |
+|---|---|---|
+| `--color-accent` | `#5B5FED` | **唯一品牌色**（主按钮、激活态、链接、焦点环） |
+| `--color-accent-hover` | `#4A4ECC` | 品牌色 hover |
+| `--color-accent-light` | `#EEEDFF` | 品牌色浅底（tag / 选中背景） |
+| `--color-accent-subtle` | `#F6F5FF` | 品牌色极浅底 |
+| `--color-success` | `#219B5E` | 成功 / 在线 |
+| `--color-warning` | `#E8922C` | 警告 |
+| `--color-error` | `#D9383A` | 错误 / 危险 |
+| `--color-info` | `#3B82F6` | 信息 |
+| （各语义的 `-light` 变体） | `#E6F7EE` / `#FEF4E8` / `#FDEBEB` / `#EBF2FE` | 浅底色块 |
+
+### 边框 / 侧栏
+| 语义名 | Hex | 角色 |
+|---|---|---|
+| `--color-border` | `#E3E6EB` | 默认边框 |
+| `--color-border-light` | `#EEF0F4` | 极浅分隔线 |
+| `--color-border-hover` | `#CDD2DA` | 边框 hover |
+| `--color-sidebar-bg` | `#F5F6F9` | 侧栏背景 |
+| `--color-sidebar-hover` | `#EAECF2` | 侧栏项 hover |
+| `--color-sidebar-active` | `#E1E3F0` | 侧栏项激活 |
+
+### 渐变 / Gradients（新增，源自"护眼科技感 + 渐变"需求）
+平台允许**克制**的渐变，用于背景 / 装饰 / 主行动点，绝非赛博朋克式高饱和。所有渐变必须先定义为 token：
+| 语义名 | 值 | 角色 |
+|---|---|---|
+| `--gradient-brand` | `linear-gradient(135deg, #EEEDFF 0%, #E3F0FF 100%)` | Hero / 区块浅底（淡蓝紫 → 淡青蓝） |
+| `--gradient-brand-strong` | `linear-gradient(135deg, #5B5FED 0%, #4F8DF9 100%)` | 主 CTA / Banner 强调（品牌色渐变，不刺眼） |
+| `--gradient-aurora` | `radial-gradient(60% 60% at 30% 20%, rgba(91,95,237,.10), transparent 70%)` | 仅 Hero 装饰光斑，绝不直接衬文字 |
+
+**渐变铁律**：
+- 渐变只作背景 / 装饰 / CTA；**承载正文文字的表面必须纯色**（`#FFFFFF` / `#F8F9FB`），确保 ≥4.5:1。
+- 拒绝全屏流动 / 循环渐变动画（aurora 8–12s loop）作用于文字区；装饰光斑在 `prefers-reduced-motion` 下静止。
+- 不引入品牌色之外的第三色相做渐变（仅「靛蓝 → 青蓝」的同系过渡）。
+
+**对比度约束**：文本在浅色表面上至少 4.5:1（WCAG AA）。`--color-text-tertiary` 仅用于非关键提示，不用于正文。
+
+## 3. Typography Rules
+
+- **字体**：`Inter`（正文/标题）+ `JetBrains Mono`（代码、模型 ID、token、技术参数）。中文回退系统字体。
+  - CSS import：`@import url('https://fonts.googleapis.com/css2?family=Inter:wght@300;400;500;600;700;800;900&family=JetBrains+Mono:wght@400;500;600&display=swap');`
+- **字阶（scale）**：
+  | Token | 尺寸 | 用途 |
+  |---|---|---|
+  | `--text-xs` | 11px | 角标 / 极次要 |
+  | `--text-sm` | 13px | 辅助文本 / 列表项 |
+  | `--text-base` | 14px | 正文默认 |
+  | `--text-md` | 15px | 稍强调正文 |
+  | `--text-lg` | 18px | 小标题 |
+  | `--text-xl` | 22px | 区块标题 |
+  | `--text-2xl` | 28px | 页面标题 |
+  | `--text-3xl` | 36px | Hero / 大标题 |
+- **字重**：正文 400，标题/强调 500–600，数字/统计可 700–800。避免过度加粗（≤600 为主）。
+- **行高**：正文 `line-height: 1.6`；标题 1.3–1.4。
+- **中文**：优先 Inter 的拉丁字形 + 系统中文回退；避免中文用 mono。
+
+## 4. Component Stylings
+
+（完整 CSS 样板见 `design-system/MASTER.md`；此处为快速参考。所有组件需 `cursor: pointer`、hover 过渡 150–300ms、可见 focus 环。）
+
+### Buttons
+- **Primary**：`background: var(--color-accent); color:#fff; border-radius: var(--radius-md); padding: 10px 18px; font-weight:500;` hover → `--color-accent-hover` + `translateY(-1px)`。
+- **Secondary**：透明底 + `1px solid var(--color-accent)` + 品牌色文字；hover 浅底 `--color-accent-subtle`。
+- **Ghost**：无边框无底，hover 仅 `--color-bg-hover`；用于工具栏图标按钮。
+- **Danger**：`var(--color-error)` 文本/边框，确认类操作用。
+
+### Cards / Panels
+- `background: var(--color-bg-secondary); border:1px solid var(--color-border); border-radius: var(--radius-lg); padding: var(--space-2xl);`
+- hover（可点击卡片）：`box-shadow: var(--shadow-lg); translateY(-2px)`。
+- 数据卡（KPI）：上方 label（tertiary）+ 大数字（text-2xl, weight 700）+ 趋势小标。
+
+### Inputs / Textarea / Select
+- `padding:10px 14px; border:1px solid var(--color-border); border-radius: var(--radius-md); font-size: var(--text-base); background: var(--color-bg-secondary);`
+- focus：`border-color: var(--color-accent); box-shadow: 0 0 0 3px var(--color-accent-light); outline:none;`
+- placeholder：`var(--color-text-tertiary)`。
+
+### Navigation / Sidebar
+- 宽 `--sidebar-width: 240px`（折叠 64px）；项高 ~40px，圆角 `--radius-md`，hover/active 用 `--color-sidebar-hover` / `--color-sidebar-active`；激活项左或文字用品牌色。
+- 顶部 header 高 `--header-height: 56px`，承载主操作与全局搜索。
+
+### Tags / Badges / Chips
+- 用 `--color-accent-light` 浅底 + 品牌色文字表示"能力/标签"；语义状态用对应 `-light` 底（success/warning/error/info）。
+- 图标统一用 **Lucide**（见 §7），禁止 emoji 当图标。
+
+### Modals / Drawers
+- overlay：`rgba(0,0,0,0.5)` + `backdrop-filter: blur(4px)`。
+- 弹窗：`background:#fff; border-radius: var(--radius-xl); padding: var(--space-3xl); box-shadow: var(--shadow-xl);` 右侧抽屉（detail drawer）用于 Agent/技能详情。
+
+### Glassmorphism（轻量玻璃拟态变体）
+用于浮层 / 导航 / Hero 叠加 / 横幅，营造通透科技感（技能库 Glassmorphism 条目：backdrop blur 10–20px、半透明白 15–30%、细边框）。
+```css
+.glass {
+  background: rgba(255,255,255,0.65);
+  backdrop-filter: blur(16px) saturate(140%);
+  -webkit-backdrop-filter: blur(16px) saturate(140%);
+  border: 1px solid rgba(255,255,255,0.7);
+  box-shadow: var(--shadow-md);
+}
+```
+- 浮层导航 / 横幅 / Hero 卡片用 `.glass`；**正文内容卡保持纯白 `#FFFFFF`**（对比与清晰度优先）。
+- 文字在玻璃面上必须 ≥4.5:1（玻璃面下若为渐变底，需加深文字或加底纹）。
+
+### Neumorphism（默认禁用）
+用户原话提到"轻拟态（Neumorphism）或玻璃拟态的轻量化变体"。技能库明确标注 Neumorphism **对比度低（⚠ Low contrast）**，不利护眼。
+**决策：默认禁用完整新拟态**；若需"轻量"立体感，仅允许在**无文字的装饰表面**用极淡 inset 阴影，且不得影响可读性。优先采用 Glassmorphism 轻量变体。
+
+## 5. Layout Principles
+
+- **间距阶梯**（必须用语义 token，禁止随意像素）：`xs4 / sm8 / md12 / lg16 / xl20 / 2xl24 / 3xl32 / 4xl40 / 5xl48`。
+- **栅格**：内容最大宽度 1440px 居中；主工作区用 12 列弹性栅格；卡片间距 `--space-lg`。
+- **留白哲学**：区块间 `--space-3xl`~`--space-5xl`；卡片内 `--space-2xl`；避免贴边，页面左右留 `--space-2xl`+。
+- **圆角**：小组件 `sm6/md8`，卡片/面板 `lg12`，弹窗 `xl16`，全圆 `--radius-full`（头像/徽标/药丸按钮）。
+- **App Shell**：左侧 sidebar（工作区导航）+ 顶 header（全局操作）+ 主内容区；IM Bot / 技能详情用右侧 drawer 不离开上下文。
+
+## 6. Depth & Elevation
+
+阴影层级（柔和、低透明，营造"浮起"而非"描边"）：
+| Token | 值 | 用途 |
+|---|---|---|
+| `--shadow-xs` | `0 1px 2px rgba(0,0,0,.04)` | 内部分隔 |
+| `--shadow-sm` | `0 1px 3px rgba(0,0,0,.06)` | 静态卡 |
+| `--shadow-md` | `0 4px 12px rgba(0,0,0,.06)` | 卡片 / 按钮 |
+| `--shadow-lg` | `0 12px 32px rgba(0,0,0,.08)` | hover 卡 / 下拉 |
+| `--shadow-xl` | `0 20px 48px rgba(0,0,0,.10)` | 弹窗 / 浮层 |
+
+规则：表面层级靠"背景明度 + 阴影"双信号区分；禁用重投影与硬黑边。
+
+## 7. Do's and Don'ts
+
+**Do**
+- 所有可点击元素加 `cursor: pointer` 与可见 hover/focus 态。
+- 用 Lucide SVG 图标；技术参数用 JetBrains Mono。
+- 状态用语义色；品牌表达只用 `--color-accent`。
+- 动效克制（150–300ms ease），尊重 `prefers-reduced-motion`。
+- 加载态用 skeleton shimmer，避免生硬 spinner。
+
+**Don't**
+- ❌ 用 emoji 当图标。
+- ❌ 引入除靛蓝外的第二个"品牌色"（除非语义状态）。
+- ❌ 低对比文本（<4.5:1）。
+- ❌ hover 用 `scale` 导致布局位移。
+- ❌ 瞬时状态切换（无过渡）。
+- ❌ 焦点态不可见（键盘可达性）。
+- ❌ 在 `global.css` 之外散落硬编码 hex。
+
+## 8. Responsive Behavior
+
+断点：`375px`（手机）/ `768px`（折叠 sidebar 为 64px 或抽屉）/ `1024px`（平板）/ `1440px`（桌面最大宽）。
+- 移动端：sidebar 转**底部 tab 栏**（前台门户）或**左侧抽屉**（后台，因菜单项多）；主内容单列；触摸目标 ≥44px。
+- 平板：sidebar 折叠 64px，悬停展开。
+- 栅格在窄屏降列数（12→6→1）。
+- 禁止横向滚动；表格在窄屏转卡片或横向滚动容器（包 `overflow-x-auto`）。
+- 必须 `<meta name="viewport" content="width=device-width, initial-scale=1">`；固定导航需 `padding-top` 补偿高度，避免遮挡首屏内容。
+
+## 10. SEO & GEO 规范（前台必须）
+
+平台需"不推广也能被搜索引擎与各大模型联网搜索（GEO）发现"。
+
+### 结构（语义化 HTML5）
+- 每页一个 `<h1>`；区块用 `<section>` / `<article>`；技能卡用 `<article>` 包裹（标题 `<h2>`/`<h3>`）。
+- 必须 `<meta name="viewport">`、`<title>`、`<meta name="description">`、Open Graph 标签。
+- 前台用 `<header><nav><main><footer>` 语义骨架；后台为应用壳，SEO 权重低。
+
+### 富媒体摘要（Rich Snippets / JSON-LD）
+- 技能页 / 技能卡：`SoftwareApplication` schema，含 `aggregateRating`、`offers`（`price:0` / 订阅）、`downloadCount`。
+- 技能市场：`BreadcrumbList`；痛点 / FAQ 区：`FAQPage`。
+- 预留展示槽：评分星、价格、下载量在卡片右上角（Lucide 图标 + 数字，非 emoji）。
+
+### 关键词突出（GEO 友好）
+- 核心词「无限Token」「AI变现」「办公提效」「低成本养龙虾（= 低成本微调 / 托管模型）」用 `.kw` 样式（品牌色 + 600 字重）在首页价值区高亮。
+- `.kw { color: var(--color-accent); font-weight:600; }`
+
+### 技术
+- `sitemap.xml` + `robots.txt`；技能详情独立可索引 URL；所有图片 `alt`。
+
+## 11. 页面级布局总览（前台 + 后台）
+
+> 详细页级 override 将在实际开发时落入 `design-system/pages/*.md`（Master + Overrides）。此处为总览与验收基准。
+
+### 前台首页（Home）
+1. 浮层玻璃顶栏（logo + 主导航 + 登录 / 注册）
+2. Hero：轮播 Banner（技能广告位）+ 平台定位一句话 + 主 CTA
+3. 平台定位区：图标 + 短文网格（痛点：API 贵 / Prompt 难调试 / 数据孤岛 / 无变现渠道）
+4. 平台价值区：可视化数据点（低价订阅 / 无限 Token / 垂直办公模板 / 交易市场 / 低成本养龙虾）
+5. 热门技能榜 Top5（排行榜 / 徽章）
+6. Footer（SEO 链接 + 富媒体摘要）
+
+### 技能市场（Skill Market）
+- 顶部广告位 → 左侧筛选（分类 / 场景标签）→ 右侧卡片流（每排 5，图标 / 名称 / 简介 / 下载量）
+- 分页：每页 100，上下翻页；每个技能 = `<article>` + JSON-LD
+
+### 应用服务（Apps）
+- 网格布局；每应用独立卡片（名称 / 介绍 / 「进入应用」按钮）
+
+### 用户工作台（Workspace，登录后）
+- 左侧固定导航：AI 聊天 / IM Bot（子：微信 / 企微 / 飞书 / QQ / 悟空 IM）/ 知识库 / 技能市场 / 应用服务 / Token 驾驶舱 / 会员订阅 / 进化看板 / 个人设置
+- 右侧内容区留白；移动端导航转抽屉
+
+### 后台数据驾驶舱（Admin Dashboard）
+- 6 张 KPI 卡：总用户 / 7日活跃、模型统计（启用 / 全部）、对话统计（有效 / 活跃窗口）、知识库文档数、今日订阅（成功）、Token 消耗（今日 / 本周）
+- 大模型消耗趋势（近 30 天 面积图）
+- 操作日志 + 审计日志 双栏（每 20 条 / 页，可下载）
+- 其余后台：AI 技能中心 / 平台运营 / 商业变现 / 系统管理（标准 B 端布局，侧栏分类清晰）
+
+## 12. Agent Prompt Guide
+
+> 当被要求"做/改一个七虎AI 的页面或组件"时，代理必须：
+> 1. 先读本文件（DESIGN.md）与 `design-system/MASTER.md`；
+> 2. 颜色/间距/圆角/字体一律引用 `:root` token，禁止新硬编码；
+> 3. 品牌色固定 `#5B5FED`，语义色仅表状态；
+> 4. 图标用 Lucide；代码/ID 用 JetBrains Mono；
+> 5. 组件带 hover + focus + 150–300ms 过渡；
+> 6. 完成后 `npm run build` 并确认 `dist` 含改动，再请用户硬刷新验收。

+Qihu-AIFlow 统一可观测基座 (Phase 2.1)
+=====================================
+提供贯穿一次请求的全局链路 ID（trace_id）与结构化日志能力，
+为后续重构（上下文引擎、媒体/LLM 成本归因）建立回归基线。
+
+设计原则（Strangler Fig 增量）：
+- 纯增量埋点，不改任何既有接口的返回结构。
+- 向后兼容现有 `logging.getLogger(__name__)` 用法：trace_id 由 root logger 的
+  TraceIdFilter 自动注入，调用方无需改动。
+- 不引入第三方依赖（structlog 未安装），自带可选的 JSON formatter。
+
+使用方式：
+    from app.core.observability import set_trace_id, get_trace_id, span
+
+    # 在中间件里为每个请求注入：
+    set_trace_id(request_id)
+
+    # 在关键调用处打计时 span（自动带 trace_id）：

+}
+```
+
+---
+
+## Style Guidelines
+
+**Style:** Warm Tech Minimalism
+
+**Keywords:** clean, precise, data-dense, soft surfaces, indigo accent, generous whitespace
+
+**Best For:** AI PaaS consoles, developer platforms, agent/workflow editors
+
+**Key Effects:** Subtle hover lift (translateY -1 to -2px), 150-300ms ease transitions, soft shadow escalation, skeleton shimmer for loading, fade/slide micro-entrances.
+
+### Page Pattern
+
+**Pattern Name:** App Shell + Dashboard Grid
+
+- **Conversion Strategy:** Core value shown immediately via workspace/chat; primary action (新建对话/部署) persistent in header and sidebar.
+- **CTA Placement:** Sticky header + sidebar primary action; contextual CTAs inside cards.
+- **Section Order:** Sidebar > Workspace(Chat/Agents/Skills/MCP) > Main content grid > Detail drawer
+
+---
+
+## Anti-Patterns (Do NOT Use)
+
+- ❌ Ornate decoration
+- ❌ Low contrast text
+- ❌ Missing focus states
+- ❌ Emojis as icons
+- ❌ Layout-shifting scale hovers
+- ❌ Instant state changes
+
+### Additional Forbidden Patterns
+
+- ❌ **Emojis as icons** — Use SVG icons (Heroicons, Lucide, Simple Icons)
+- ❌ **Missing cursor:pointer** — All clickable elements must have cursor:pointer
+- ❌ **Layout-shifting hovers** — Avoid scale transforms that shift layout
+- ❌ **Low contrast text** — Maintain 4.5:1 minimum contrast ratio
+- ❌ **Instant state changes** — Always use transitions (150-300ms)
+- ❌ **Invisible focus states** — Focus states must be visible for a11y
+
+---
+
+## Pre-Delivery Checklist
+
+Before delivering any UI code, verify:
+
+- [ ] No emojis as icons (use SVG: Heroicons/Lucide)
+- [ ] cursor-pointer on all clickable elements
+- [ ] Hover states with smooth transitions (150-300ms)
+- [ ] Light mode: text contrast 4.5:1 minimum
+- [ ] Focus states visible for keyboard nav
+- [ ] prefers-reduced-motion respected
+- [ ] Responsive: 375px, 768px, 1024px, 1440px
+- [ ] No content hidden behind fixed navbars
+- [ ] No horizontal scroll on mobile

+# 版本号规范 (Versioning)
+
+> 适用：七虎AI PaaS 平台 (qihuaiflow) 全部发布物（源码、Docker 镜像、线上环境）。
+> 生效版本：`v2026.07.18.1`（取代旧 `-recover` 标签体系）。
+
+---
+
+## 1. 版本号格式
+
+```
+vYYYY.MM.DD.N
+```
+
+| 段 | 含义 | 示例 |
+|----|------|------|
+| `YYYY` | 年（4 位） | 2026 |
+| `MM` | 月（2 位，补零） | 07 |
+| `DD` | 日（2 位，补零） | 18 |
+| `N` | **当日**递增序号，从 `1` 开始，同日多次发布顺延 | 1, 2, 3 … |
+
+- 同一天第 1 次发布 = `v2026.07.18.1`，第 2 次 = `v2026.07.18.2`。
+- 跨天序号**重置**：次日第 1 次发布 = `v2026.07.19.1`。
+- 序号不与全局总发布数绑定，只跟"当天第几次"有关，便于人类快速判断发布日期与顺序。
+
+## 2. 环境标签 (prod / test)
+
+每个版本必须标注环境，用于正式版与测试版的环境切割：
+
+- **`prod`** — 正式版，面向最终用户，质量门禁（测试全绿 + 备份完成）必须达标。
+- **`test`** — 测试版 / 灰度 / 预发布，允许未完全冻结，但同样需要镜像备份。
+
+环境信息记录在 `VERSION` 文件的 `ENV=` 字段，并写入 git tag 注解与镜像 metadata。
+
+## 3. 三类发布物的对应关系
+
+一次发布同时产生三个相互关联的制品：
+
+| 制品 | 命名 | 工具 |
+|------|------|------|
+| Git 标签 | `v2026.07.18.1`（注解含 `env=prod`） | `git tag -a` |
+| Docker 镜像 | `qihu-aiflow:v2026.07.18.1` | `docker tag` / `docker commit` |
+| 运行态快照（回滚点） | `qihu-aiflow:backup-YYYYMMDD-NNN` | `scripts/backup_before_deploy.py` |
+
+> **关键纪律**：`backup-*` 是部署**前**对当前健康运行态的快照（防线）；`v*` 镜像/标签是部署**后**的发布物（成果）。两者不是一个东西。
+
+## 4. 发布流程（SOP）
+
+每次部署严格遵守以下步骤：
+
+```bash
+# 0. 在改任何代码之前，先打部署前镜像备份（强制）
+python scripts/backup_before_deploy.py --env prod --note "发布 v2026.07.18.1 前快照"
+
+# 1. 在容器中完成代码修改
+#    （编辑 /app/... → 必要时 npm run build → docker restart）
+
+# 2. 把容器内最新源码 docker cp 回宿主仓库
+docker cp qihu-aiflow:/app /www/wwwroot/qihuaiflow   # 仅后端；前端 dist 同理
+
+# 3. 更新 VERSION 文件（VERSION / ENV / DATE / BACKUP_IMAGE）
+
+# 4. 提交并打标签
+cd /www/wwwroot/qihuaiflow
+git add -A
+git commit -m "release: v2026.07.18.1 (prod) — <一句话变更摘要>"
+git tag -a v2026.07.18.1 -m "prod | Phase0 工程纪律止血：备份SOP + 版本规范 + 测试基建"
+git push origin main
+git push origin v2026.07.18.1
+
+# 5. 固化发布镜像（可选但推荐，便于回滚到有版本号的镜像）
+docker commit qihu-aiflow qihu-aiflow:v2026.07.18.1
+```
+
+## 5. 回滚流程
+
+若发布后发现问题：
+
+```bash
+# 方案 A：回滚到部署前快照（最快，不依赖源码）
+docker tag qihu-aiflow:backup-20260718-001 qihu-aiflow:with-deps
+docker restart qihu-aiflow
+
+# 方案 B：回滚到某个历史发布镜像
+docker tag qihu-aiflow:v2026.07.18.1 qihu-aiflow:with-deps
+docker restart qihu-aiflow
+
+# 方案 C：源码回滚
+git checkout v2026.07.18.1
+docker cp /www/wwwroot/qihuaiflow/app qihu-aiflow:/app
+docker restart qihu-aiflow
+```
+
+## 6. VERSION 文件维护
+
+- 仓库根目录 `VERSION` 为机器 + 人共读的清单，必须包含 `VERSION=` / `ENV=` / `DATE=` / `BASE_IMAGE=` / `BACKUP_IMAGE=` 五个字段。
+- 每次发布更新 `VERSION` 与 `DATE`，并在"本版本变更"小节追加一行摘要。
+- `BACKUP_IMAGE` 必须填写本次发布前实际生成的 `backup-*` 标签，作为可审计的回滚点。
+
+## 7. 旧标签处理
+
+- 旧 `-recover` 系列标签（`v2026.07.12-recover` 等）**保留不删**，仅停止使用，避免丢失历史快照索引。
+- 旧镜像标签 `AIFlow v2.0.1` / `v2026.07.14` / `v2026.07.14-nav` 视为历史资产，新发布不再沿用该命名。
