**Problem:**
Deployment failure notifications were not being sent due to two bugs:
1. **Timing Issue in next() function:**
- When failed() called next(FAILED), the database still had status "in_progress"
- The notification check looked for ALREADY failed status (not found yet)
- Status was updated AFTER the check, losing the notification
2. **Direct Status Update:**
- Healthcheck failures directly updated status to FAILED
- Bypassed next() entirely, no notification sent
**Solution:**
Refactored status transition logic with clear separation of concerns:
- Moved notification logic AFTER status update (not before)
- Created transitionToStatus() as single source of truth
- Added completeDeployment() and failDeployment() for clarity
- Extracted status-specific side effects into dedicated methods
- Updated healthcheck failure to use failDeployment()
**Benefits:**
- ✅ Notifications sent for ALL failure scenarios
- ✅ Clear, self-documenting method names
- ✅ Single responsibility per method
- ✅ Type-safe using enum instead of strings
- ✅ Harder to bypass notification logic accidentally
- ✅ Backward compatible (old next() preserved)
**Changed:**
- app/Jobs/ApplicationDeploymentJob.php (+101/-21 lines)
