华东交大教务小工具：成绩、课表、培养方案、实际选课与 GPA 规划
An unofficial privacy-first Chrome extension for East China Jiaotong University (ECJTU / 华东交通大学). It syncs the pages a student already opens in the academic system and presents GPA, timetable, curriculum, course-registration status, semester estimates, and academic-planning reminders in one local interface.

- Log in to the official ECJTU academic system and open the grade, timetable, curriculum, and course-registration pages you want to sync.
Do not move or delete the unpacked folder while the extension is installed.
The extension treats each page as a different source of truth:
- Actual registration decides which courses are being taken.
- Curriculum provides official credits and recommended semesters.
- Issued grades are locked facts.
- Pending courses may be estimated locally.
- Timetables are stored as semester snapshots to avoid showing stale courses as current.
See PRIVACY.md. The extension requests only storage plus exact ECJTU academic-system page matches. It does not save passwords, cookies, browsing history, full URLs, student IDs, class identifiers, or raw exam/retake records.
The release package contains no real grade, timetable, student record, account, email address, or absolute local path.
This project is unofficial and is not endorsed by East China Jiaotong University. GPA planning and academic-risk reminders are personal estimates, not official academic-status decisions. The extension depends on the current structure of jwxt.ecjtu.edu.cn and may require updates after a site redesign.
node --test tests/static.test.mjsThe workflow, academic-domain rules, failure boundaries, and real-device testing were led by aibuqin-code. Most implementation was developed with AI assistance. The project is published with that boundary stated explicitly rather than presenting AI-assisted code as fully hand-written.
