+4. 专家登录系统查看评审任务
+5. 专家在线评审：
+   - 查看项目详情
+   - 查看附件材料
+   - 填写评审意见
+   - 给出评分
+   - 选择通过/不通过/修改后通过
+6. 系统汇总评审意见
+7. 若通过，项目状态变更为"初审通过"
+8. 若不通过，项目状态变更为"初审不通过"，学生可修改后重新提交
+
+中期检查阶段：
+1. 管理员发起中期检查
+2. 学生填写中期检查报告
+3. 上传阶段性成果材料
+4. 指导教师评审中期报告
+5. 系统记录中期检查结果

+2. 上传最终成果材料
+3. 管理员分配验收专家
+4. 专家评审验收材料
+5. 系统记录验收结果
+6. 项目状态变更为"已结题"
+```
+
+
+```
+2. 系统读取项目信息：
+   - 项目级别
+   - 项目成员排名
+   - 结题评价等级
+7. 若有异议，可提交申诉
+8. 管理员审核申诉
+```
+
+### 3.4 成果管理流程

+# Innovation Platform
+
+Innovation Platform is a Spring Boot based demo for university innovation and entrepreneurship project management.
+
+## What is included
+
+- Authentication endpoints powered by Sa-Token
+- Project CRUD APIs with pagination
+- Project dashboard statistics endpoint
+- Static admin dashboard prototype at `backend/src/main/resources/static/index.html`
+- Example SQL schema and seed data
+
+## Demo accounts
+
+- `admin / admin123`
+- `teacher001 / admin123`
+- `student001 / admin123`
+
+## Notable API routes
+
+- `POST /api/auth/login`
+- `POST /api/auth/register`
+- `POST /api/auth/logout`
+- `GET /api/projects`
+- `GET /api/projects/stats`
+- `GET /api/projects/{id}`
+- `POST /api/projects`
+- `PUT /api/projects/{id}`
+- `DELETE /api/projects/{id}`
+
+## Dashboard prototype
+
+When the backend is running, open `/index.html` to use the lightweight dashboard prototype. It can:
+
+- request a login token
+- load project statistics
+- query recent projects with keyword, type, level, and status filters
+- visualize status and level breakdowns
+- view leader and advisor names directly in project rows
+
+## Notes
+
+- This repository snapshot was recovered from an archive, so local build and runtime validation depend on the target machine having Java and Maven available.
+- The current environment used for editing did not include a working Maven installation, so changes were verified statically only.
+- The SQL bootstrap files were refreshed into a clean UTF-8 seed set and made idempotent with `ON DUPLICATE KEY UPDATE`.
