- Replace Enum.map |> Enum.join with Enum.map_join for efficiency
- Extract helper functions to reduce nesting depth from 4 to 2
- Rename is_current_cycle? to current_cycle? following Elixir conventions
- Implemented regenerate_cycles_on_type_change helper in Member resource
- Cycles that haven't ended yet (cycle_end >= today) are deleted and regenerated
- Paid and suspended cycles remain unchanged (not deleted)
- CycleGenerator reloads member with new membership_fee_type_id
- Adjusted tests to work with current cycles only (no future cycles)
- All integration tests passing
Phase 4 completed: Cycle regeneration on type change
Add tests to verify that copy and open-email buttons are disabled
when no members are selected and enabled after selection.
Also verify that the counter shows the correct count.
- Remove Process.sleep calls from integration tests (tests run synchronously in SQL sandbox)
- Improve error handling: membership_fee_type_not_found now returns changeset error instead of just logging
- Clarify partial_failure documentation: successful_cycles are not persisted on rollback
- Update documentation: joined_at → join_date, left_at → exit_date
- Document PostgreSQL advisory locks per member (not whole table lock)
- Document gap handling: explicitly deleted cycles are not recreated
- Add create_member_with_cycles helper that uses fixed 'today' date
- Update tests to use explicit 'today:' option instead of Date.utc_today()
- Prevents test failures when current date changes (e.g., in 2026+)
- Tests now explicitly delete and regenerate cycles with fixed dates
- Ensures consistent test behavior regardless of execution date
- 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
- Remove exit_date filter from generate_cycles_for_all_members query
- Inactive members now get cycles generated up to their exit_date
- Add tests for inactive member processing and exit_date boundary
- Document exit_date == cycle_start behavior (cycle still generated)
