Attendance Module

Attendance Module Context

Context

Attendance merges two input sources — biometric devices and manual teacher entry. The merge rule drives payroll (teacher presence) and student absence letters.

Steps

1. Inject the merge rule
2. Warn about the duplicate class column
3. Remind Claude not to "fix" the duplicate without a ticket

Output

Key files

• app/DailyAttendance.php
• AttendanceController.php
• daily_attendance migration

Business logic

• Merge rule: device entry wins on conflict with manual entry
• Late threshold: configured per-institution (not hardcoded)
