- 主要修改：[.env](file:///e:/Desktop/CICD/.env)、[create-db.ts](file:///e:/Desktop/CICD/scripts/create-db.ts)

### 3. 种子脚本完全重写（小学场景）
- 完全重写 `scripts/seed.ts`，实现小学完整场景初始化
- 数据规模：
  - 1 所学校（实验小学）、2 个年级（一/二年级）、每年级 2 个班级
  - 8 名教师（每班 2 名：1 班主任 + 1 科任，跨班覆盖语数外 3 科）
  - 24 名学生（每班 6 名）+ 24 名家长
  - 3 科教材（语数外各 1 本）+ 章节 + 知识点

- 17 个顺序步骤，耗时约 127s
- 主要修改：[seed.ts](file:///e:/Desktop/CICD/scripts/seed.ts)

### 4. 迁移脚本系统重构
- **问题**：旧迁移系统存在多个缺陷
  - `0011_ai_providers.sql` 未在 `_journal.json` 中注册，导致 `drizzle-kit migrate` 失败
  - 缺少多数 snapshot 文件（仅存 0008、0009）
  - 迁移 SQL 使用复杂 PREPARE/EXECUTE 条件模式，维护困难
- **修复**：清理全部旧迁移文件与 meta 目录，使用 `drizzle-kit generate` 从 schema 重新生成
  - 生成单一迁移文件 `0000_perfect_pestilence.sql`，包含全部 49 张表
  - journal 重置为单条记录，snapshot 完整
- **新增 npm 脚本**（package.json）：
  - `db:create`：创建数据库
  - `db:push`：直接同步 schema（开发用）
  - `db:setup`：一键 create → migrate → seed
- 主要修改：[package.json](file:///e:/Desktop/CICD/package.json)、drizzle/ 目录

### 5. 验证
- 干净数据库全流程测试：`db:create` → `db:migrate` → `db:seed` 全部通过

## 2026-02-24

### 1. Credentials 登录与密码安全修复
*   **密码哈希规范化**：
    *   注册时统一生成标准 bcrypt 前缀（`$2a/$2b/$2y`），确保数据库内哈希格式一致。
    *   登录时对非标准前缀（如 `$10$...`）自动补全为 `$2b$...` 再校验，避免格式不一致导致登录失败。
*   **登录一致性修复**：
    *   登录校验不再对密码做 `trim()`，避免前后空格导致的 bcrypt 比对失败。
*   **调试排障（已回收）**：
    *   临时加入安全日志定位失败原因（不输出明文），定位后已移除。

### 2. 验证
*   `npm run typecheck`：通过
*   `npm run lint`：存在既有告警（未新增）

## 2026-01-15

### 1. Schedule Module Optimization
*   **Visual Overhaul (`schedule-view.tsx`)**:
    *   Refactored the schedule grid to match the exact design of the `ClassScheduleGrid` widget.
    *   Implemented a clean, borderless layout with no grid lines for a modern look.
    *   **Time-Based Positioning**: Replaced grid-row logic with absolute positioning based on time (8:00 - 18:00 range) using percentage calculations (`getPositionStyle`).
    *   **Color Coding**: Added `getSubjectColor` to auto-assign thematic colors (blue for Math, purple for Physics, etc.) based on course names.
    *   **Card Design**: Refined course cards with vertical centering, better spacing, and removed unnecessary UI elements (like the "+" button in headers).

*   **Filter Bar Refinement (`schedule-filters.tsx`)**:
    *   **Minimalist Design**: Removed borders and shadows from the class selector and buttons to integrate seamlessly with the background.
    *   **Center Label**: Added a dynamic, absolute-centered text label that updates based on selection:
        *   Shows "All Classes" when no filter is active.
        *   Shows "{Class Name}" when a specific class is selected.
    *   **Simplified Controls**: Removed the "Reset" button (X icon) entirely for a cleaner interface.
    *   **Ghost Buttons**: Styled the "Add Event" button as a ghost variant with muted colors.

### 2. Architecture & Cleanup
*   **Insights Module Removal**:
    *   Deleted the entire `src/app/(dashboard)/teacher/classes/insights` directory as the feature was deemed redundant.
    *   Removed `insights-filters.tsx` component.
    *   Updated `navigation.ts` to remove the "Insights" link from the sidebar.
    *   *Note*: Preserved `getClassHomeworkInsights` in `data-access.ts` as it's still used by the Class Detail dashboard widgets.

### 3. Verification
*   **Type Safety**: Ran `npm run typecheck` multiple times during refactoring to ensure no regressions (Passed).
*   **Build**: Attempted to clear build cache to resolve a chunk loading error (Windows permission issue encountered but workaround applied).

## 2026-01-14

### 1. Class Management Refactoring (Role Separation)
*   **Separation of Duties**:
    *   Moved class creation and management responsibilities from the generic Teacher view to a dedicated Management view.
    *   Created **Grade Management Page** at `src/app/(dashboard)/management/grade/classes/page.tsx` for Grade Directors and Admins.
    *   Teachers can now only **Join Classes** (via code) or view their assigned classes in "My Classes".

*   **New Components & Pages**:
    *   `GradeClassesView` (`src/modules/classes/components/grade-classes-view.tsx`): A comprehensive table view for managing classes within specific grades, supporting creation, editing, and deletion.
    *   `GradeClassesPage`: Server Component that fetches managed grades and classes using strict RBAC (Role-Based Access Control).

*   **Teacher "My Classes" Update (`my-classes-grid.tsx`)**:
    *   Removed the "Create Class" button/dialog.
    *   Added a **"Join Class"** dialog that accepts a 6-digit invitation code.
    *   Updated styling to use standard design system colors (`bg-card`, `border-border`) instead of hardcoded gradients.

### 2. Backend & Logic Updates
*   **Data Access (`data-access.ts`)**:
    *   Implemented `getGradeManagedClasses`: Fetches classes for grades where the user is either a Grade Head or Teaching Head.
    *   Implemented `getManagedGrades`: Fetches the list of grades managed by the user for the creation dropdown.
    *   Updated `getTeacherClasses`: Now returns both **owned classes** (assigned by admin) and **enrolled classes** (joined via code).
    *   Fixed a SQL syntax error in `getGradeManagedClasses` (unescaped backticks in template literal).

*   **Server Actions (`actions.ts`)**:
    *   Added `createGradeClassAction`, `updateGradeClassAction`, `deleteGradeClassAction`: These actions enforce that the user manages the target grade before performing operations.
    *   Updated `joinClassByInvitationCodeAction`: Expanded to allow Teachers (role `teacher`) to join classes, not just Students.

### 3. Verification
*   **RBAC**: Verified that users can only manage classes for grades they are assigned to.
*   **Flow**: Verified Teacher "Join Class" flow correctly redirects and updates the list.
*   **Syntax**: Fixed TypeScript/SQL syntax errors in the new data access functions.

### 4. Class UI/UX Optimization
*   **Students Management Interface (`students-table.tsx`, `students-filters.tsx`)**:
    *   **Enhanced Table**: Added student avatars, gender display, and join date.
    *   **Pagination**: Implemented client-side pagination (10 items per page) to handle larger classes gracefully.
    *   **Status Filtering**: Added "Active/Inactive" filter with visual status badges (Emerald for active, muted for inactive).
    *   **Data Access**: Updated `getClassStudents` to fetch extended user profile data and support server-side status filtering.

*   **Class Detail Dashboard (`/teacher/classes/my/[id]/page.tsx`)**:
    *   **Dashboard Layout**: Refactored into a responsive two-column layout (Main Content + Sidebar).
    *   **Key Metrics**: Added a 4-card stats grid at the top displaying critical insights:
        *   Total Students (Active/Inactive breakdown)
        *   Schedule Items (Weekly sessions)
        *   Active Assignments (Overdue count)
        *   Class Average (Based on graded submissions)
    *   **Sidebar Widgets**: Added "Class Schedule" and "Homework History" widgets for quick access to temporal data.
    *   **Visual Polish**: Integrated `lucide-react` icons throughout for better information scanning.

## 2026-01-13

### 1. Navigation & Layout Improvements
*   **Dynamic Breadcrumbs (`site-header.tsx`)**:
    *   Replaced hardcoded "Dashboard > Overview" breadcrumbs with a dynamic system.
    *   Implemented a path-to-title lookup using `NAV_CONFIG` from `src/modules/layout/config/navigation.ts`.
    *   Added logic to filter out root role segments (admin/teacher/student/parent) for cleaner paths.
    *   Added fallback capitalization for segments not found in the config.
    *   Refactored `SiteHeader` to use `usePathname` for real-time route updates.

### 2. Code Quality & Bug Fixes
*   **Type Safety (`homework-grading-view.tsx`)**:
    *   Fixed a TypeScript error where a boolean expression was returning `boolean | undefined` which is not a valid React node (implicit `true` check added).
    *   Resolved "Calling setState synchronously within an effect" React warning by initializing state lazily instead of using `useEffect`.
    *   Fixed implicit `any` type errors in map functions.
*   **Linting**:
    *   Cleaned up unused imports across multiple files (`exam-actions.tsx`, `exam-assembly.tsx`, `textbook-reader.tsx`, etc.).
    *   Fixed unescaped HTML entities in `student-dashboard-header.tsx` and others.
    *   Removed unused variables to clear ESLint warnings.
*   **Refactoring**:
    *   Updated `TextbookCard` to support `hideActions` prop for better reuse in student views.
    *   Added missing `Progress` component to `src/shared/components/ui/progress.tsx`.

### 3. Verification
*   Ran `npm run typecheck`: **Passed** (0 errors).
*   Ran `npm run lint`: **Passed** (0 errors, 28 warnings remaining for unused vars/components that may be needed later).
