# Phase 6 Plan 2: Action Scheduler Integration Summary
**Action Scheduler 3.9.3 integrated with 50-user batch scheduling for async email processing**
## Accomplishments
- Downloaded and integrated Action Scheduler 3.9.3 library from WooCommerce GitHub
- Library loaded early in main plugin file before other code for proper initialization
- Created DDHH_JM_Scheduler helper class for managing async email batch actions
- Implemented schedule_mentor_notification_batch() method that chunks users into batches of 50
- Async actions enqueued with unique flag to prevent duplicates and email-notifications group for organization
- Scheduler class initialized in main plugin lifecycle
- Infrastructure ready for Phase 06-03 to implement actual email sending callbacks
## Files Created/Modified
- `vendor/action-scheduler/` - Action Scheduler 3.9.3 library (102 files, 17,820+ lines)
- `includes/class-scheduler.php` - Scheduler helper class with batch scheduling API
- `ddhh-job-manager.php` - Added Action Scheduler include before other code, added scheduler class include
- `includes/class-ddhh-job-manager.php` - Initialized scheduler hooks in plugin lifecycle
## Decisions Made
None - straightforward implementation following Context7 best practices for Action Scheduler integration.
## Issues Encountered
None - library downloaded successfully, integration completed without errors.
