# 📋 Activity Log

## System Auditing (Deep Dive)

The Activity Log is an immutable, chronologically ordered ledger of every significant action performed by an Administrator or Examiner. It is critical for compliance and accountability.

### Log Architecture:

- Action Taxonomy: Differentiates between 'Created', 'Updated', 'Deleted', and 'Auth' (Login/Logout) events.
- Contextual Data: Records the exact User ID who performed the action, their IP Address, and the User-Agent payload.
- Target Tracking: Specifies exactly which database model was altered (e.g., "Updated Exam ID 5").
- Security Investigations: If an exam's passing percentage is mysteriously altered, or a student profile is deleted, the Activity Log provides the precise forensics to identify "Who did it, and when?"
