- Change algorithm to start from last existing cycle instead of start_date
- Deleted cycles (gaps) are no longer automatically filled
- Add test to verify gaps remain unfilled
- Update documentation to clarify gap handling behavior
- Replace weak assertions (>= 0, if length > 0) with concrete expectations
- Remove unnecessary Process.sleep calls (tests run synchronously)
- Add get_member_cycles helper for direct cycle verification
- Tests now validate actual generated cycles instead of relying on async behavior
