Bug Timeline:
═════════════
BEFORE (Broken):
notification_options=None
↓
get_capabilities(None, None)
↓
AttributeError: 'NoneType' object has no attribute '...'
↓
❌ Server fails to start
AFTER (Fixed):
notification_options=NotificationOptions()
↓
get_capabilities(NotificationOptions(), {})
↓
✅ Server starts successfully
Test Protection:
test_no_attribute_error_during_initialization
↓
Verifies no AttributeError is raised
↓
✅ Regression prevented
