# Test Evidence: Attendance policy defaults and boundaries

- **Test type:** Unit
- **Requirement IDs:** `ATT-001`, `ATT-002`, `ATT-003`, `ATT-004`
- **Scenario IDs:** `AC-ATT-001`
- **Test class/method:** `com.lab.labtimesheet.feature.attendance.model.AttendancePolicyTest`
- **Implementation commit:** `71901d1670f633a1b594bdce3348efebe73fc175`

## Protected behavior

The seeded policy applies from 1970-01-01 with the required timezone, schedule,
workdays, grace values, leave quota, and penalty. Grace outside 0..720 or a
checkout cutoff at midnight is rejected.

## Test method

Plain JUnit constructs the immutable policy and timeline directly, resolves two
dates, and exercises the validation boundary without Spring or persistence.

## Hand-derived expected result

08:30 plus 30 minutes makes the inclusive on-time boundary 09:00. 15:30 plus
30 minutes makes the inclusive checkout boundary 16:00. A 23:30 end plus 30
minutes reaches midnight and is invalid.
