package scheduling

// Package scheduling contains tests for time blockers CRUD handlers.
//
// Test Coverage:
//   - ListTimeBlockers: GET /api/admin/time-blockers - List all blockers
//   - CreateTimeBlocker: POST /api/admin/time-blockers - Create blocker (admin)
//   - DeleteTimeBlocker: DELETE /api/admin/time-blockers/{id} - Delete blocker (admin)
//   - CheckTimeBlockerOverlap: Helper to check for overlapping blockers
//   - GetTimeBlockersInRange: Helper to get blockers in date range
//
// Authentication: Create/Delete endpoints require admin role.
