+# Quick Note Modal Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 在顶部“写文章”按钮左侧新增“速记”入口，提供可拖拽/可全屏的轻量速记弹框，支持上传、手动保存、每用户唯一内容和未保存离开保护。
+
+**Architecture:** 前端在 `AppShell` 挂载速记入口与弹框，弹框拆分为容器层（拖拽、全屏、未保存拦截）和编辑器层（轻量 Vditor + 上传复用）。后端新增用户唯一 `quick_notes` 存储与 `GET/PUT /api/me/quick-note` 接口，服务层统一处理 upsert、长度校验和换行标准化。全链路以 TDD 驱动，按“先失败测试 -> 最小实现 -> 通过测试 -> 提交”小步推进。
+
+**Tech Stack:** Nuxt 4、Vue 3、TypeScript、Bun test、Drizzle ORM（SQLite）
+

+- [ ] **Step 1: 写失败检查（确认 quick_notes 尚未存在）**
+
+```bash
+rg "quick_notes|quickNotes" packages/drizzle-pkg/database/sqlite/schema/content.ts packages/drizzle-pkg/lib/schema/content.ts
+```
+
+Expected: 无匹配结果。
+
+- [ ] **Step 2: 运行检查确认失败基线**
+
+Run: `rg "quick_notes|quickNotes" packages/drizzle-pkg/database/sqlite/schema/content.ts packages/drizzle-pkg/lib/schema/content.ts`  
+Expected: Exit code 1（无命中）
+
+- [ ] **Step 3: 增加表定义与导出**

+```
+
+- [ ] **Step 5: 输出验证证据**
+
+Run: `git show --stat --oneline -1`  
+Expected: 展示 quick-note 相关文件变更清单，便于 PR 描述直接引用。
+
+---
+
+## Self-Review
+
+1. **Spec coverage:** 已覆盖入口位置、近全屏+全屏切换、拖拽、轻量编辑器+上传、用户唯一存储、手动保存、双重未保存提醒、测试与验收。  
+2. **Placeholder scan:** 无 TBD/TODO/“后续补充”；每个任务均给出具体路径、命令、预期输出和最小代码片段。  
+3. **Type consistency:** 前后统一使用 `quick-note` 路由命名、`savedContent/draftContent/isDirty` 状态命名、`GET/PUT /api/me/quick-note` 接口约定。

+# Quick Note Modal Design
+
+## Background
+
+Current writing flow is centered on article creation. The user needs a faster way to jot down temporary or reusable notes without opening the full post creation flow. The quick note should be accessible near the top "Write Article" button and support a lightweight editing experience with media upload.
+
+## Goals
+
+- Add a `Quick Note` entry to the left side of the top `Write Article` button.
+- Open a draggable modal that defaults to near-fullscreen and can switch to true fullscreen.
+- Provide a lightweight editor with upload support.
+- Store one unique quick note per authenticated user.
+- Use manual save only.
+- Protect unsaved changes when closing the modal or leaving the page.
+
+## Non-goals
+
+- No auto-save in this iteration.
+- No multi-note list, categorization, or version history.
+- No public sharing capability.
+- No cross-user collaboration.
+
+## User Experience
+
+### Entry and Open
+
+- A `Quick Note` button appears to the left of `Write Article`.
+- Clicking `Quick Note` opens the modal and loads the current user's note from backend.
+- If no note exists, editor opens with empty content.
+
+### Modal Behavior
+
+- Default state is near-fullscreen (small viewport margins).
+- Modal is draggable by title bar when not in fullscreen.
+- Top-right button toggles `Fullscreen` and `Exit Fullscreen`.
+- Fullscreen mode disables dragging.
+- Exiting fullscreen restores draggable mode and previous near-fullscreen frame behavior.
+
+### Editor Behavior
+
+- Use a lightweight markdown editor configuration to reduce startup and UI complexity.
+- Keep upload capability aligned with existing article editor upload flow.
+- Editing updates local draft only until user clicks `Save`.
+
+### Save and Unsaved Protection
+
+- Save button triggers manual persistence.
+- Unsaved state (`isDirty`) is determined by comparing `draftContent` against `savedContent`.
+- On modal close attempt with unsaved content, show confirmation dialog:
+  - Confirm: close and discard unsaved changes in current session.
+  - Cancel: keep modal open.
+- On page leave/refresh/navigation with unsaved content while modal is open, trigger browser `beforeunload` confirmation.
+- After successful save, dirty state is cleared.
+
+## Architecture and Components
+
+### Frontend
+
+- Add `Quick Note` trigger in the top action area where `Write Article` is rendered.
+- Add `QuickNoteModal.vue`:
+  - Modal shell, header controls, drag behavior, fullscreen toggle, close interception.
+  - Unsaved-close confirmation handling.
+  - Register/unregister `beforeunload` guard while open.
+- Add `QuickNoteEditor.vue`:
+  - Lightweight editor wrapper.
+  - Minimal toolbar and markdown input area.
+  - Upload hook integration by reusing existing editor upload bridge/uploader path.
+- State model inside modal:
+  - `savedContent: string`
+  - `draftContent: string`
+  - `isDirty: boolean` (derived)
+  - `isSaving: boolean`
+  - `isLoading: boolean`
+
+### Backend
+
+- Introduce persistent user-unique quick note record.
+- Data model (`quick_notes` or project-consistent naming):
+  - `id`
+  - `user_id` (unique index)
+  - `content` (text)
+  - `created_at`
+  - `updated_at`
+- Add API endpoints:
+  - `GET /api/me/quick-note`
+    - Returns current user's note content.
+    - Returns empty content if no record exists.
+  - `PUT /api/me/quick-note`
+    - Accepts `content`.
+    - Performs upsert by `user_id`.
+    - Returns saved content and timestamps.
+
+## Data and Validation Rules
+
+- Endpoint access requires authenticated `me` context.
+- Content must be string.
+- Enforce max content length (proposed: 200,000 chars) to prevent abuse and oversized payloads.
+- Normalize line endings server-side to keep storage consistent.
+
+## Error Handling
+
+- Load failure: show inline load error with retry option.
+- Save failure: keep `draftContent` untouched, preserve dirty state, and show save error toast/message.
+- Concurrent upsert conflicts (rare): service layer retries update path once after conflict.
+
+## Testing Strategy
+
+### Frontend Unit Tests
+
+- `QuickNoteModal` open/close, fullscreen toggle, drag enable/disable switching.
+- Dirty-state derived behavior for save success/failure.
+- Close interception when dirty.
+- `beforeunload` guard registration lifecycle and dirty-condition trigger.
+- `QuickNoteEditor` upload insertion path and save event behavior.
+
+### Backend Unit Tests
+
+- `GET /api/me/quick-note` with existing note.
+- `GET /api/me/quick-note` with no existing note.
+- `PUT /api/me/quick-note` create path and update path.
+- Validation rejection for non-string or oversized payload.
+- Auth rejection for unauthenticated access.
+
+### Manual Acceptance
+
+- Quick Note button opens modal in near-fullscreen.
+- Fullscreen/exit button works as expected.
+- Draggable behavior works only outside fullscreen.
+- Unsaved close prompt appears on close attempts.
+- Browser leave prompt appears on refresh/navigate with unsaved changes.
+- Save persists content; reopening shows latest saved state.
+- Upload works in quick note editor and follows existing media behavior.
+
+## Rollout and Compatibility
+
+- Feature can ship without affecting existing article editor behavior.
+- No migration impact on posts data.
+- New quick note storage is isolated to authenticated user scope.
+
+## Open Decisions (Resolved)
+
+- Uniqueness scope: per authenticated user.
+- Save strategy: manual only.
+- Unsaved reminders: modal close + page leave.
+- Default view: near-fullscreen.
+- Fullscreen trigger: top-right toggle button.
+- Editor approach: lightweight editor with upload retained.
