+# 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`.
