Badges provide visual recognition for user achievements, such as completing a certain number of lessons or courses.

This issue should be implemented inside the rewards module.

What the contributor should solve:

• Define badge milestones

• Automatically award badges when milestones are reached

• Prevent duplicate badge awards

• Allow users to retrieve earned badges

Expected outcome:

• Users receive badges for milestones

• Badge data is accurate and retrievable

Complexity: Medium

GM GM!

I'm very excited about this issue! I have experience building reward systems and achievement logic where performance tracking meets automated feedback. I’m comfortable working within modular architectures like the rewards module.

My Plan:

Milestone Definitions: Define a clear structure for milestones (e.g., "Course Finisher," "First Lesson," "Consistency King").

Automated Logic: Implement a "Check & Award" trigger that runs when a lesson/course is completed to verify if a new badge is unlocked.

Integrity: Add robust checks to ensure a badge is only awarded once per milestone per user.

Retrieval: Create an efficient query/endpoint so users can view their "Trophy Case" of badges in the UI.

ETA: 2 day
