 UX 请求默认允许调整布局、交互和文案，不代表允许改变文件存储位置、接口协议、工作流语义、模型识别依据或用户数据。
 
+### 小型 UX 修改快速流程
+
+仅调整文案、图标、颜色、间距或局部交互时：查看相关差异 → 定位负责规则 → 最小修改 → 验证受影响界面 → 本地提交。
+同一任务已读过且未变化的规范不反复通读；只读相关专题，不做全仓审查，不顺手重构。
+按第 7 节选择相关检查，不默认运行全部 JS/Python 测试。检查通过后，除非又改了代码或出现新问题，不重复运行。
+没有改变职责、接口或持久化契约时，不更新架构文档或新增经验记录。提交说明由 AI 根据实际差异编写，无需用户代写。
+
+### 任务中断后的接续与快照
+
+- 开工先检查状态和差异。工作区干净时直接继续，不制造空提交。
+- 上次因额度或其他原因中断，存在属于该任务的改动时，先确认文件范围，再选择性暂存这些文件；不得使用无差别的 `git add .` 收入用户数据、凭据、临时文件或无关工作。
+- 已完成且有验证记录的改动可补正式提交；尚未验证或未完成的改动可先保存 `chore(checkpoint): <实际改动摘要>` 恢复快照，提交正文明确“未完成/验证待完成”、已做检查和下一步。快照是恢复点，不代表验收通过。
+- 后续修改和验证另作正式提交，不自动 amend、reset 或改写快照历史。若无法区分遗留文件归属，保留原状并说明，不猜测打包。
+- 长任务按可独立验证的完整阶段提交，避免把所有 Git 收尾留到最后。测试范围内检查完成后及时提交，不为额外润色拖延快照。
+- 上述快照和正式提交均只保存在本地，未经明确授权不推送。
+
 ## 2. 模块职责与规模
 
 - `web/main.js` 负责注册和接线；`ui_sidebar.js` 的 `createDOM` 负责外壳装配。新工具的完整实现放在自己的模块，不继续塞进这两个入口。

 ### Navigation and update guide
 - Sidebar icons reveal compact text labels on hover or keyboard focus while keeping their existing button size and actions. Detailed hints explain each tool; scan-state and language changes retain labels. Unclipped tooltips ensure explanations are fully readable.
-- Added a non-intrusive update guide system: instead of an automatic popup on startup, an amber breathing badge (`!` + '新指引' / 'Guide') appears in the top-right header when a new guide version is unacknowledged. Clicking opens the polished obsidian-glass guide modal with step indicator, and dismissing smoothly hides the badge and stores persistent acknowledgment. The guide can also be replayed from the Help panel footer; see `docs/architecture/update-guide.md`.
+- Update guide opens only from the persistent top-right exclamation button or Help. Dismissing never removes the entry. Sidebar labels slide upward on hover/focus; duplicate source-panel and obsolete notice styles were removed. See `docs/architecture/update-guide.md`.
 
 ### Model Source Hub (模型来源中控中心)
 - Added a unified Model Source Hub under Toolbox for dual-scope (current workflow and full library) model source URL inspection, one-click browser navigation to Civitai/HuggingFace/Liblib/ModelScope, custom source editing, workflow metadata synchronization (`extra.anomalous_model_sources`), and instant canvas `Note` node generation for non-intrusive workflow documentation.

 ## 后续 AI 更新步骤
 
 1. 先确认功能已实现及真实入口。不要在引导里承诺未上线、暂停或验证失败的功能。
 2. 在 `CURRENT_UPDATE_GUIDE.steps` 编写 1–5 个步骤，每项包含唯一 `id`、短 `icon`、`titleKey`、`bodyKey`。
 3. 在 `locales.js` 补齐这些键的中文和英文。标题说明变化，正文说明入口和用户该怎么用。禁止 HTML、可执行回调、请求及文件写入。
-4. **只有需要所有用户重新看到时才换引导 `id`**，例如 `2026-10-library-navigation`。修改错字、翻译、样式时保持 ID。不使用时间戳、随机数、Git 提交号或普通版本号自动生成 ID。
+4. **只有引导内容属于新一轮功能变化时才换 `id`**，例如 `2026-10-library-navigation`。修改错字、翻译、样式时保持 ID。不使用时间戳、随机数、Git 提交号或普通版本号自动生成 ID；换 ID 也不能自动弹窗。
 5. 配置校验会拒绝重复步骤、空步骤及缺失双语文案。配置错误只跳过引导，不应阻止插件打开；必须修正错误后再交付。
-6. 运行下方测试，再在浏览器验证首次打开、跳过后重开、帮助页重看、Esc 和中英文长文案。
+6. 运行下方相关测试，再在浏览器验证打开插件不弹窗、上方入口、跳过后手动重开、帮助页重看、Esc 和长文案。
 7. 修改现有样式规则，不在文件末尾追加覆盖包。没有明确产品决策，不增加强制阅读、自动跳转、网络请求或额外追踪。
 
 ## 生命周期与记录
 
-- 未确认的更新引导不再强制自动弹窗打扰用户，而是在面板右上角显示克制的暗色感叹号徽标（`#anomalous-update-notice-btn`）；用户主动点击时才唤起引导。
+- 面板右上角常驻感叹号按钮（`#anomalous-update-notice-btn`），提供完整的用途提示和 accessible name。只有用户点击该按钮或帮助页入口才打开引导；初始化、打开插件、版本变化都不能触发弹窗。
 - 使用原生 `dialog` 的顶层显示和焦点约束，关闭时尽可能恢复原焦点。
-- 完成、跳过、×、Esc、点击空白关闭会记录已读，并触发感叹号徽标平滑淡出消除；关闭父浏览器仅清理，不将未读引导标记为已读。
+- 完成、跳过、×、Esc、点击空白关闭会记录已读，上方入口仍然保留；关闭父浏览器仅清理，不将未读引导标记为已读。入口不需要全局事件或延时隐藏。
 - 持久化键为 `anomalous_update_guide_seen:<id>`，值为 `1`。只保存本地已读状态，不发送到服务端。
-- 存储不可用时，当前页面会话仍记住关闭状态；刷新页面后可能再次显示。
+- 存储不可用时，当前页面会话仍记住关闭状态；刷新后仍必须手动点击才能显示。
 - 同一时刻只有一个引导。重复调用不叠加弹窗；所有关闭路径通过 `closeUpdateGuide` 释放资源。
-- 帮助页的“查看更新引导”使用 `force: true`，允许重看已确认版本。
+- 上方按钮和帮助页的“查看更新引导”均使用 `force: true`，允许重看已确认版本。
 - 引导不自动点击对应功能，也不修改画布、模型、素材、导入导出限制。
